    • BACKGROUND: The Global Burden of Disease, Injuries, and Risk Factor study 2013 (GBD 2013) is the first of a series of annual updates of the GBD. Risk factor quantification, particularly of modifiable risk factors, can help to identify emerging threats to population health and opportunities for prevention. The GBD 2013 provides a timely opportunity to update the comparative risk assessment with new data for exposure, relative risks, and evidence on the appropriate counterfactual risk distribution.METHODS: Attributable deaths, years of life lost, years lived with disability, and disability-adjusted life-years (DALYs) have been estimated for 79 risks or clusters of risks using the GBD 2010 methods. Risk-outcome pairs meeting explicit evidence criteria were assessed for 188 countries for the period 1990-2013 by age and sex using three inputs: risk exposure, relative risks, and the theoretical minimum risk exposure level (TMREL). Risks are organised into a hierarchy with blocks of behavioural, environmental and occupational, and metabolic risks at the first level of the hierarchy. The next level in the hierarchy includes nine clusters of related risks and two individual risks, with more detail provided at levels 3 and 4 of the hierarchy. Compared with GBD 2010, six new risk factors have been added: handwashing practices, occupational exposure to trichloroethylene, childhood wasting, childhood stunting, unsafe sex, and low glomerular filtration rate. For most risks, data for exposure were synthesised with a Bayesian meta-regression method, DisMod-MR 2.0, or spatial-temporal Gaussian process regression. Relative risks were based on meta-regressions of published cohort and intervention studies. Attributable burden for clusters of risks and all risks combined took into account evidence on the mediation of some risks such as high body-mass index (BMI) through other risks such as high systolic blood pressure and high cholesterol.FINDINGS: All risks combined account for 57·2% (95% uncertainty interval [UI] 55·8-58·5) of deaths and 41·6% (40·1-43·0) of DALYs. Risks quantified account for 87·9% (86·5-89·3) of cardiovascular disease DALYs, ranging to a low of 0% for neonatal disorders and neglected tropical diseases and malaria. In terms of global DALYs in 2013, six risks or clusters of risks each caused more than 5% of DALYs: dietary risks accounting for 11·3 million deaths and 241·4 million DALYs, high systolic blood pressure for 10·4 million deaths and 208·1 million DALYs, child and maternal malnutrition for 1·7 million deaths and 176·9 million DALYs, tobacco smoke for 6·1 million deaths and 143·5 million DALYs, air pollution for 5·5 million deaths and 141·5 million DALYs, and high BMI for 4·4 million deaths and 134·0 million DALYs. Risk factor patterns vary across regions and countries and with time. In sub-Saharan Africa, the leading risk factors are child and maternal malnutrition, unsafe sex, and unsafe water, sanitation, and handwashing. In women, in nearly all countries in the Americas, north Africa, and the Middle East, and in many other high-income countries, high BMI is the leading risk factor, with high systolic blood pressure as the leading risk in most of Central and Eastern Europe and south and east Asia. For men, high systolic blood pressure or tobacco use are the leading risks in nearly all high-income countries, in north Africa and the Middle East, Europe, and Asia. For men and women, unsafe sex is the leading risk in a corridor from Kenya to South Africa.INTERPRETATION: Behavioural, environmental and occupational, and metabolic risks can explain half of global mortality and more than one-third of global DALYs providing many opportunities for prevention. Of the larger risks, the attributable burden of high BMI has increased in the past 23 years. In view of the prominence of behavioural risk factors, behavioural and social science research on interventions for these risks should be strengthened. Many prevention and primary care policy options are available now to act on key risks.FUNDING: Bill & Melinda Gates Foundation.

  • CSF and blood biomarkers for the diagnosis of Alzheimer's disease: a systematic review and meta-analysis.
  • 2016
  • Ingår i: The Lancet. Neurology. - 1474-4465. ; 15:7, s. 673-684
  • Tidskriftsartikel (refereegranskat)abstract
    • Alzheimer's disease biomarkers are important for early diagnosis in routine clinical practice and research. Three core CSF biomarkers for the diagnosis of Alzheimer's disease (Aβ42, T-tau, and P-tau) have been assessed in numerous studies, and several other Alzheimer's disease markers are emerging in the literature. However, there have been no comprehensive meta-analyses of their diagnostic performance. We systematically reviewed the literature for 15 biomarkers in both CSF and blood to assess which of these were most altered in Alzheimer's disease.

  • Correlates of smoking susceptibility among adolescents in a peri-urban area of Nepal: a population-based cross-sectional study in the Jhaukhel-Duwakot Health Demographic Surveillance Site
  • 2014
  • Ingår i: Global Health Action. - : Informa UK Limited. - 1654-9880 .- 1654-9716. ; 7, s. 1-14
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Susceptibility to smoking is defined as an absence of firm commitment not to smoke in the future or when offered a cigarette by best friends. Susceptibility begins in adolescence and is the first step in the transition to becoming an established smoker. Many scholars have hypothesized and studied whether psychosocial risk factors play a crucial role in preventing adolescent susceptibility to smoking or discourage susceptible adolescents from becoming established smokers. Our study examined sociodemographic and family and childhood environmental factors associated with smoking susceptibility among adolescents in a peri-urban area of Nepal. Design: We conducted a population-based cross-sectional study during October-November 2011 in the Jhaukhel-Duwakot Health Demographic Surveillance Site (JD-HDSS) located in a peri-urban area near Kathmandu, the capital city of Nepal, where tobacco products are easily available. Trained local enumerators conducted face-to-face interviews with 352 respondents aged 14-16. We used stepwise logistic regression to assess sociodemographic and family and childhood environmental factors associated with smoking susceptibility. Results: The percentage of smoking susceptibility among respondents was 49.70% (95% CI: 44.49; 54.93). Multivariable analysis demonstrated that smoking susceptibility was associated with smoking by exposure of adolescents to pro-tobacco advertisements (AOR [adjusted odds ratio] = 2.49; 95% CI: 1.46-4.24), the teacher (2.45; 1.28-4.68), adolescents attending concerts/picnics (2.14; 1.13-4.04), and smoking by other family members/relatives (1.76; 1.05-2.95). Conclusions: Smoking susceptible adolescents are prevalent in the JD-HDSS, a peri-urban community of Nepal. Several family and childhood environmental factors increased susceptibility to smoking among Nepalese nonsmoking adolescents. Therefore, intervention efforts need to be focused on family and childhood environmental factors with emphasis on impact of role models smoking, refusal skills in social gatherings, and discussing harmful effects of smoking with family members and during gatherings with friends.

  • Establishing a health demographic surveillance site in Bhaktapur district, Nepal : initial experiences and findings
  • 2012
  • Ingår i: BMC Research Notes. - : BioMed Central. - 1756-0500. ; 5
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: A health demographic surveillance system (HDSS) provides longitudinal data regarding health and demography in countries with coverage error and poor quality data on vital registration systems due to lack of public awareness, inadequate legal basis and limited use of data in health planning. The health system in Nepal, a low-income country, does not focus primarily on health registration, and does not conduct regular health data collection. This study aimed to initiate and establish the first HDSS in Nepal.RESULTS: We conducted a baseline survey in Jhaukhel and Duwakot, two villages in Bhaktapur district. The study surveyed 2,712 households comprising a total population of 13,669. The sex ratio in the study area was 101 males per 100 females and the average household size was 5. The crude birth and death rates were 9.7 and 3.9/1,000 population/year, respectively. About 11% of births occurred at home, and we found no mortality in infants and children less than 5 years of age. Various health problems were found commonly and some of them include respiratory problems (41.9%); headache, vertigo and dizziness (16.7%); bone and joint pain (14.4%); gastrointestinal problems (13.9%); heart disease, including hypertension (8.8%); accidents and injuries (2.9%); and diabetes mellitus (2.6%). The prevalence of non-communicable disease (NCD) was 4.3% (95% CI: 3.83; 4.86) among individuals older than 30 years. Age-adjusted odds ratios showed that risk factors, such as sex, ethnic group, occupation and education, associated with NCD.CONCLUSION: Our baseline survey demonstrated that it is possible to collect accurate and reliable data in a village setting in Nepal, and this study successfully established an HDSS site. We determined that both maternal and child health are better in the surveillance site compared to the entire country. Risk factors associated with NCDs dominated morbidity and mortality patterns.

  • Perceived risks and benefits of cigarette smoking among Nepalese adolescents: a population-based cross-sectional study.
  • 2013
  • Ingår i: BMC public health. - : Springer Science and Business Media LLC. - 1471-2458. ; 13
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The perceived risks and benefits of smoking may play an important role in determining adolescents' susceptibility to initiating smoking. Our study examined the perceived risks and benefits of smoking among adolescents who demonstrated susceptibility or non susceptibility to smoking initiation. METHODS: In October--November 2011, we conducted a population-based cross-sectional study in Jhaukhel and Duwakot Villages in Nepal. Located in the mid-hills of Bhaktapur District, 13 kilometers east of Kathmandu, Jhaukhel and Duwakot represent the prototypical urbanizing villages that surround Nepal's major urban centers, where young people have easy access to tobacco products and are influenced by advertising. Jhaukhel and Duwakot had a total population of 13,669, of which 15% were smokers. Trained enumerators used a semi-structured questionnaire to interview 352 randomly selected 14- to 16-year-old adolescents. The enumerators asked the adolescents to estimate their likelihood (0%--100%) of experiencing various smoking-related risks and benefits in a hypothetical scenario. RESULTS: Principal component analysis extracted four perceived risk and benefit components, excluding addiction risk: (i) physical risk I (lung cancer, heart disease, wrinkles, bad colds) ;(ii) physical risk II (bad cough, bad breath, trouble breathing);(iii) social risk (getting into trouble, smelling like an ashtray); and (iv) social benefit(looking cool, feeling relaxed, becoming popular, and feeling grown-up). The adjusted odds ratio of susceptibility increased 1.20-fold with each increased quartile in perception of physical Risk I. Susceptibility to smoking was 0.27- and 0.90-fold less among adolescents who provided the highest estimates of physical Risk II and social risk, respectively. Similarly, susceptibility was 2.16-fold greater among adolescents who provided the highest estimates of addiction risk. Physical risk I, addiction risk, and social benefits of cigarette smoking related positively, and physical risk II and social risk related negatively, with susceptibility to smoking. CONCLUSION: To discourage or prevent adolescents from initiating smoking, future intervention programs should focus on communicating not only the health risks but also the social and addiction risks as well as counteract the social benefits of smoking.

  • Jhaukhel-Duwakot Health Demographic Surveillance Site, Nepal: 2012 follow-up survey and use of skilled birth attendants
  • 2015
  • Ingår i: Global Health Action. - : Informa UK Limited. - 1654-9880 .- 1654-9716. ; 8
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Estimates of disease burden in Nepal are based on cross-sectional studies that provide inadequate epidemiological information to support public health decisions. This study compares the health and demographic indicators at the end of 2012 in the Jhaukhel-Duwakot Health Demographic Surveillance Site (JD-HDSS) with the baseline conducted at the end of 2010. We also report on the use of skilled birth attendants (SBAs) and associated factors in the JD-HDSS at the follow-up point. Design: We used a structured questionnaire to survey 3,505 households in the JD-HDSS, Bhaktapur, Nepal. To investigate the use of SBAs, we interviewed 434 women who had delivered a baby within the prior 2 years. We compared demographic and health indicators at baseline and follow-up and assessed the association of SBA services with background variables. Results: Due to rising in-migration, the total population and number of households in the JD-HDSS increased (13,669 and 2,712 in 2010 vs. 16,918 and 3,505 in 2012). Self-reported morbidity decreased (11.1% vs. 7.1%, respectively), whereas accidents and injuries increased (2.9% vs. 6.5% of overall morbidity, respectively). At follow-up, the proportion of institutional delivery (93.1%) exceeded the national average (36%). Women who accessed antenatal care and used transport (e.g. bus, taxi, motorcycle) to reach a health facility were more likely to access institutional delivery. Conclusions: High in-migration increased the total population and number of households in the JD-HDSS, a peri-urban area where most health indicators exceed the national average. Major morbidity conditions (respiratory diseases, fever, gastrointestinal problems, and bone and joint problems) remain unchanged. Further investigation of reasons for increased proportion of accidents and injuries are recommended for their timely prevention. More than 90% of our respondents received adequate antenatal care and used institutional delivery, but only 13.2% accessed adequate postnatal care. Availability of transport and use of antenatal care was associated positively with institutional delivery.

  • Associations between parents' subjective time pressure and mental health problems among children in the Nordic countries : a population based study
  • 2015
  • Ingår i: BMC Public Health. - : Springer Science and Business Media LLC. - 1471-2458. ; 15:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The home, the family and the parents represent a context of everyday life that is important for child health and development, with parent-child relationships highlighted as crucial for children's mental health. Time pressure is an emerging feature of modern societies and previous studies indicates that parents with children living at home experience time pressure to a greater extent than people with no children living at home. Previous studies of children's mental health in relation to parents' time pressure are lacking. Hence, the purpose of this study was to examine the association between parents' subjective time pressure and mental health problems among children in the Nordic countries as well as potential disparities between boys and girls in different age groups.METHODS: 4592 children, aged 4-16 from Denmark, Finland, Norway and Sweden, participating in the 2011 version of the NordChild study, were included. The Strength and Difficulties Questionnaire was used to measure children's mental health and associations to parents' time pressure were assessed by multiple logistic regression analysis.RESULTS: Among children of parents experiencing time pressure, 18.6% had mental health problems compared to 10.1% among children of parents experiencing time pressure not or sometimes. The odds of mental health problems were higher among both boys (OR 1.80 95% CI 1.32-2.46) and girls (OR 1.95 95% CI 1.42-2.66) if their parents experienced time pressure when adjusted for financial stress. The highest prevalence of mental health problems in the case of parental time pressure was found among girls 13-16 years old (23.6%) and the lowest prevalence was found among boys 13-16 years old (10.7%).CONCLUSIONS: In this study an association between parents' subjective time pressure and increased mental health problems among children was found. Given that time pressure is a growing feature of modern societies, the results might contribute to an explanation as to mental health problems are common among children in the Nordic countries in spite of otherwise favourable conditions. Additional research on the linkage between parents' experienced time pressure and children's and adolescents' mental health problems is needed to confirm the novel findings of this study.

  • Adolescents' knowledge and opinions about smoking : a qualitative study from the Jhaukhel-Duwakot Health Demographic Surveillance Site, Bhaktapur District, Nepal
  • 2018
  • Ingår i: International Journal of Adolescent Medicine and Health. - : Walter de Gruyter. - 0334-0139 .- 2191-0278. ; 30:1

    • BACKGROUND: The use of tobacco products among adolescents in Southeast Asia represents a major public health burden. Two out of ten adolescents attending school are tobacco users and several factors influence them to initiate tobacco use. Most studies related to tobacco use are quantitative, whereas qualitative studies exploring adolescents' smoking behavior and their views, knowledge and experiences are scarce.OBJECTIVE: To gain a deep understanding of Nepalese adolescents' knowledge and opinions about smoking and reasons for smoking initiation.SUBJECTS: Adolescents from four secondary schools in the Bhaktapur district, Nepal.METHODS: Eight focus-group discussions were conducted with 71 adolescents aged 13-16 years and from grades 8-10. Data were analyzed using manifest qualitative content analysis.RESULTS: The participants knew that smoking represents health risks as well as socio-economic risks, but few described the addictive nature of tobacco and health risks related to passive smoking. Most participants related smoking initiation to the smoking behavior of peers and family members, but easy accessibility to cigarettes, ineffective rules and regulations, and exposure to passive smoking also created environments for smoking. Some expressed confidence to resist peer pressure and refuse to start smoking, but also expressed the need for prevention strategies in schools and for governmental initiatives, such as more strict implementation of tobacco control and regulations to prevent and reduce smoking.CONCLUSION: Curbing the tobacco epidemic in Nepal requires healthy public policies and multifaceted interventions to address the knowledge gap on health consequences associated with smoking among adolescents, teachers and parents/adults.

  • Worldwide prevalence of non-partner sexual violence: a systematic review
  • 2014
  • Ingår i: The Lancet. - 0140-6736. ; 383:9929, s. 1648-1654
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Several highly publicised rapes and murders of young women in India and South Africa have focused international attention on sexual violence. These cases are extremes of the wider phenomenon of sexual violence against women, but the true extent is poorly quantified. We did a systematic review to estimate prevalence. Methods: We searched for articles published from Jan 1, 1998, to Dec 31, 2011, and manually search reference lists and contacted experts to identify population-based data on the prevalence of women's reported experiences of sexual violence from age 15 years onwards, by anyone except intimate partners. We used random effects meta-regression to calculate adjusted and unadjusted prevalence for regions, which we weighted by population size to calculate the worldwide estimate. Findings: We identified 7231 studies from which we obtained 412 estimates covering 56 countries. In 2010 7·2% (95% CI 5·2-9·1) of women worldwide had ever experienced non-partner sexual violence. The highest estimates were in sub-Saharan Africa, central (21%, 95%CI 4·5-37·5) and sub-Saharan Africa, southern (17·4%, 11·4-23·3). The lowest prevalence was for Asia, south (3·3%, 0-8·3). Limited data were available from sub-Saharan Africa, central, North Africa/Middle East, Europe, eastern, and Asia Pacific, high income. Interpretation: Sexual violence against women is common worldwide, with endemic levels seen in some areas, although large variations between settings need to be interpreted with caution because of differences in data availability and levels of disclosure. Nevertheless, our findings indicate a pressing health and human rights concern. Funding: South African Medical Research Council, Sigrid Rausing Trust, WHO. © 2014 World Health Organization.

  • Targeted intervention for the ultra poor in rural Bangladesh: Does it make any difference in their health-seeking behaviour?
  • 2006
  • Ingår i: Social Science & Medicine. - : Elsevier BV. - 0277-9536. ; 63:11, s. 2899-2911
  • Tidskriftsartikel (refereegranskat)abstract
    • It is now well recognised that regular microcredit intervention is not enough to effectively reach the ultra poor in rural Bangladesh, in fact it actively excludes them for structural reasons. A grants-based integrated intervention was developed (with health inputs to mitigate the income-erosion effect of illness) to examine whether such a targeted intervention could change the health-seeking behaviour of the ultra-poor towards greater use of health services and "formal allopathic" providers during illness, besides improving their poverty status and capacity for health expenditure. The study was carried out in three northern districts of Bangladesh with high density of ultra poor households, using a pre-test/post-test control group design. A pre-intervention baseline (2189 interventions and 2134 controls) survey was undertaken in 2002 followed by an intervention (of 18 months duration) and a post-intervention follow-up survey of the same households in 2004. Structured interviews were conducted to elicit information on health-seeking behaviour of household members. Findings reveal an overall change in health-seeking behaviour in the study population, but the intervention reduced self-care by 7 percentage units and increased formal allopathic care by 9 percentage units. The intervention increased the proportion of non-deficit households by 43 percentage units, as well as the capacity to spend more than Tk. 25 for treatment of illness during the reference period by 11 percentage units. Higher health expenditure and time (pre- to -post-intervention period) was associated with increased use of health care from formal allopathic providers. However, gender differences in health-seeking and health-expenditure disfavouring women were also noted. The programmatic implications of these findings are discussed in the context of improving the ability of health systems to reach the ultra poor.

  • A hybrid, effectiveness-implementation research study protocol targeting antenatal care providers to provide female genital mutilation prevention and care services in Guinea, Kenya and Somalia
  • 2021
  • Ingår i: BMC Health Services Research. - : Springer Science and Business Media LLC. - 1472-6963. ; 21:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BackgroundIn settings with high prevalence of female genital mutilation (FGM), the health sector could play a bigger role in its prevention and care of women and girls who have undergone this harmful practice. However, ministries of health lack clear policies, strategic plans or dedicated funding to implement anti-FGM interventions. Along with limited relevant knowledge and skills to prevent the practice of FGM and care for girls and women living with FGM, health providers have limited interpersonal communication skills and self-efficacy, while some may have supportive attitudes towards FGM and its medicalization. We propose to test the effectiveness of a health system strengthening intervention that includes training antenatal care (ANC) providers on person-centred communication (PCC) for FGM prevention.MethodsThis will be a two-level, hybrid, effectiveness-implementation research study using a cluster randomized trial design in Guinea, Kenya and Somalia conducted over a 6months period. In each country, within pre-selected regions/counties, 60 ANC clinics will be randomized to intervention and control arms. At baseline, all clinics will receive the level one intervention involving provision of FGM-related clinical guidelines and handbook as well as anti-FGM policies and posters. At month 3, intervention clinics will receive the level two intervention comprising of a training for ANC providers on PCC to challenge their FGM-related attitudes and build their communication skills to effectively provide FGM prevention counselling. A process evaluation will be conducted to understand 'how' and 'why' the intervention package achieves intended results. Multi-level regression modelling will be used for quantitative data analysis while qualitative data will be assessed using thematic content analysis to determine the effectiveness, feasibility and acceptability of the different intervention levels.DiscussionThe proposed study will strengthen the knowledge base regarding how to effectively involve health providers in FGM prevention and care.Trial registrationTrial registration and date: PACTR201906696419769 (June 3rd, 2019).

    • Malaria-endemic countries are encouraged to increase, expedite, and standardize care based on parasite diagnosis and treat confirmed malaria using oral artemisinin-based combination therapy (ACT) or rectal artesunate plus referral when patients are unable to take oral medication.In 172 villages in 3 African countries, trained community health workers (CHWs) assessed and diagnosed children aged between 6 months and 6 years using rapid histidine-rich protein 2 (HRP2)-based diagnostic tests (RDTs). Patients coming for care who could take oral medication were treated with ACTs, and those who could not were treated with rectal artesunate and referred to hospital. The full combined intervention package lasted 12 months. Changes in access and speed of care and clinical course were determined through 1746 random household interviews before and 3199 during the intervention.A total of 15 932 children were assessed: 6394 in Burkina Faso, 2148 in Nigeria, and 7390 in Uganda. Most children assessed (97.3% [15 495/15 932]) were febrile and most febrile cases (82.1% [12 725/15 495]) tested were RDT positive. Almost half of afebrile episodes (47.6% [204/429]) were RDT positive. Children eligible for rectal artesunate contributed 1.1% of episodes. The odds of using CHWs as the first point of care doubled (odds ratio [OR], 2.15; 95% confidence interval [CI], 1.9-2.4; P < .0001). RDT use changed from 3.2% to 72.9% (OR, 80.8; 95% CI, 51.2-127.3; P < .0001). The mean duration of uncomplicated episodes reduced from 3.69 ± 2.06 days to 3.47 ± 1.61 days, Degrees of freedom (df) = 2960, Student's t (t) = 3.2 (P = .0014), and mean duration of severe episodes reduced from 4.24 ± 2.26 days to 3.7 ± 1.57 days, df = 749, t = 3.8, P = .0001. There was a reduction in children with danger signs from 24.7% before to 18.1% during the intervention (OR, 0.68; 95% CI, .59-.78; P < .0001).Provision of diagnosis and treatment via trained CHWs increases access to diagnosis and treatment, shortens clinical episode duration, and reduces the number of severe cases. This approach, recommended by the World Health Organization, improves malaria case management.ISRCTN13858170.

  • Community pharmacists' perspectives towards automated pharmacy systems and extended community pharmacy services: An online cross-sectional study
  • 2023
  • Ingår i: Exploratory Research in Clinical and Social Pharmacy. - 2667-2766. ; 12
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Private sector partnerships through community pharmacies are essential for effective healthcare integration to achieve the United Nations 2030 Agenda for Sustainable Development Goals. This partnership can provide significant clinical outcomes and reduce health system expenditures by delivering services focused on patient-centred care, such as public health screening and medication therapy management. Objectives To assess the understanding of the proposed strategic and health system reform in Saudi Arabia by exploring community pharmacists' perspectives towards the capacity and readiness of community pharmacies to use automated pharmacy systems, provide extended community pharmacy services, and identify perceived barriers. Materials and methods This multicentre, cross-sectional, web-based survey was conducted in Saudi Arabia (October–December 2021). Graphical and numerical statistics were used to describe key dimensions by the background and characteristics of the respondents, and multiple ordinal logistic regression analyses were sought to assess their associations. Results Of the 403 consenting and participating community pharmacists, most were male (94%), belonged to chain pharmacies (77%), and worked >48 h per week (72%). Automated pharmacy systems, such as electronic prescriptions, were never utilised (50%), and health screening services, such as blood glucose (76%) and blood pressure measurement (74%), were never provided. Services for medication therapy management were somewhat limited. Age groups ≤40 years, chain pharmacies, >10 years of experience and ≥ 3 pharmacists in place with <100 daily medication prescriptions and Jazan province were significantly more likely to provide all medication therapy management services than others. Operational factors were the barriers most significantly associated with the independent variables. Conclusion The results showed that most services and automated pharmacy systems remained limited and well-needed. When attempting to implement these services to drive change, community pharmacies face numerous challenges, and urgent efforts by private and government sectors are essential to improve pharmaceutical care in community pharmacy settings.

    • Background In many developed countries, the scope of community pharmacy services has extended to include advanced applications. Unlike traditional practices that focus on pharmaceutical sales, extended community pharmacy services (ECPSs) are patient-centred and typically offered by specialised healthcare centres, which improve public health, reduce pressure imposed on healthcare professionals, and rationalise health system expenditures. However, based on the findings of several studies, community pharmacies (CPs) only provide marginalised services. Public reviews are thus crucial to effectively utilise such services. This study explored CPs use among the Saudi public in terms of knowledge, attitudes, and barriers to ECPSs. Materials and methods We conducted a cross-sectional web-based survey of a non-probability sample between October and December 2021. Numerical and graphical descriptive statistics were employed with an additional analytical assessment using binary logistic regression to determine the association between participant characteristics and the barriers to ECPSs use. Results A total of 563 individuals participated in this study, approximately 33% of which revealed CPs as the first place they visit for medication concerns. Most individuals were not aware of medication therapy management and health screening services (77% and 68%, respectively). Pharmacy clinics offering private counselling and receiving patient electronic medical records were unknown to the participants (78% and 63%, respectively). A substantial proportion of the cohort considered lack of privacy (58%) and inadequate communication with community pharmacists (56%) as key barriers to the use of ECPSs. Logistic regression analysis revealed that the underdeveloped infrastructure of CPs was significantly associated with almost all factors. Conclusion Most services and facilities were found to be underutilised. Positive public attitudes were associated with concerns regarding privacy and cost of services. Consistent with Saudi Vision 2030, supporting CPs and increasing the public awareness of ECPSs have significant implications on public health.

    • Aims The purpose of this study was to evaluate the accuracy of bone-level assessments using either cone-beam computed tomography (CBCT), intra-oral peri-apical (PA) radiographs or histology following reconstructive treatment of experimental peri-implantitis. Materials and Methods Six Labrador dogs were used. Experimental peri-implantitis was induced 3 months after implant placement. Surgical treatment of peri-implantitis was performed and peri-implant defects were allocated to one of four treatment categories; no augmentation, bone graft materials with or without a barrier membrane. Six months later, intra-oral PA radiographs and block biopsies from all implants sites were obtained. Marginal bone levels (MBLs) were measured using PA radiographs, CBCT and histology. Results Significant correlations of MBL assessments were observed between the three methods. The measurements in PA radiographs consistently resulted in an overestimation of the bone level of about 0.3-0.4 mm. The agreement between the methods was not influenced by the use of bone substitute materials in the management of the osseous defects. Conclusions Although MBL assessments obtained from PA radiographs showed an overestimation compared to MBL assessments on corresponding CBCT images and histological sections, PA radiographs can be considered a reliable technique for peri-implant bone-level evaluations following reconstructive surgical therapy of experimental peri-implantitis.

  • Surgical Predictors of Early Revision Surgery After Anterior Cruciate Ligament Reconstruction: Results From the Swedish National Knee Ligament Register on 13,102 Patients.
  • 2014
  • Ingår i: The American journal of sports medicine. - : SAGE Publications. - 1552-3365 .- 0363-5465. ; 42:7, s. 1574-1582

    • BACKGROUND:An important objective of anterior cruciate ligament (ACL) registries is to detect and report early graft failure and revision surgery after ACL reconstruction. PURPOSE:To investigate surgical variables and identify predictors of revision surgery after ACL reconstruction. STUDY DESIGN:Prospective cohort study; Level of evidence, 2. METHODS:This prospective cohort study was based on data from the Swedish National Knee Ligament Register during the years 2005 through 2011. Eight surgical variables were investigated: graft selection, graft width, single-bundle or double-bundle techniques, femoral graft fixation, tibial graft fixation, injury-to-surgery interval, injuries to menisci, and injuries to cartilage. The primary endpoint was the 2-year incidence of revision surgery. Relative risks (RRs) and 95% confidence intervals (CIs) were calculated and adjusted for confounders by use of multivariate statistics. RESULTS:A total of 13,102 patients were included (5541 women [42%] and 7561 men [58%]; P < .001). Hamstring tendon autografts accounted for 90% (11,764 patients) of all reconstructions, of which 96% were performed with a single-bundle technique (11,339 patients). Patellar tendon autografts accounted for the remaining 10% (1338 patients). At index reconstruction, observed injuries to menisci and cartilage were common (40% and 28%, respectively). The overall 2-year incidence of revision surgery was 1.60% (women, 1.57%; men, 1.63%; P = .854). Patients with metal interference screw fixation of a semitendinosus tendon autograft on the tibia had a significantly reduced risk of early revision surgery (RR = 0.32; 95% CI, 0.12-0.90; P = .031). CONCLUSION:Metal interference screw fixation of a semitendinosus tendon autograft on the tibia was an independent predictor of significantly lower 2-year incidence of revision surgery. Graft selection, graft width, a single-bundle or a double-bundle technique, femoral graft fixation, the injury-to-surgery interval, and meniscus injury were not predictors of early revision surgery.

    • The last decades increasing pharmaceutical expenditures in Sweden and other western countries have created a need for reforms to reduce the trend. The aim was to analyse if reforms concerning the pharmaceutical reimbursement scheme in Sweden during the years 1986-2002 were associated with changes in cost, volume and cost per volume of pharmaceuticals. Effects of changes in the reimbursement schedule during the study period were evaluated for all registered pharmaceuticals in Sweden and for five indicator drug groups. Five policy changes during the study period were assessed. Three concerned increased patient co-payment (January 1, 1991; January 1, 1995 and June 1, 1999), one the introduction of reference based pricing and increased co-payment (January 1, 1993) and one a new structure of the reimbursement schedule (January 1, 1997). The National Corporation of Swedish Pharmacies provided pharmaceutical delivery data for all Swedish pharmacies. Possible breaks in the trend associated with the investigated reforms were analysed with linear segmented regression analysis. This showed that increased co-payments were not associated with changed level or slope of cost and volume. The new reimbursement schedule was associated with a decreased level of cost and volume, both for all drugs combined and for several of the indicator drug groups. It was also associated with an increased slope for both volume and cost in some indicator drug groups and for all drugs. Introduction of reference based pricing was associated with a reduced slope of cost/defined daily doses (DDD) in all of the indicator drug groups and for all drugs. The analysis showed that major changes in the reimbursement system such as the introduction of a new reimbursement schedule and reference based pricing were associated with reductions in cost and volume for the new reimbursement schedule and cost per volume for reference based pricing.

  • Impact of a generic substitution reform on patients' and society's expenditure for pharmaceuticals.
  • 2007
  • Ingår i: Health policy (Amsterdam, Netherlands). - : Elsevier BV. - 0168-8510. ; 81:2-3, s. 376-84
  • Tidskriftsartikel (refereegranskat)abstract
    • Sweden's pharmaceutical expenditure has increased during the last decades. On 1 October 2002 mandatory generic substitution was introduced in Sweden with the purpose to reduce the growth in pharmaceutical expenditure. The aim of the present study was to investigate if the implementation of generic substitution was associated with changes in patients' expenses and reimbursed cost for prescribed pharmaceuticals included in the Swedish Pharmaceutical Benefits Scheme (PBS). Monthly pharmacy sales data was obtained from the National Corporation of Swedish Pharmacies (Apoteket AB). The study period ranged between 1 January 2000 and 31 December 2004. Changes in pharmaceutical expenditure associated with the introduction of generic substitution were analysed with a linear segmented regression. The study comprised outpatient prescription pharmaceuticals encompassed by PBS for Sweden in total and each county council. Two different data sets were analysed. The first comprised all prescribed pharmaceuticals. The second contained only pharmaceuticals on regular prescriptions (i.e. exclusion of multidose dispensed drugs). Changes in patient co-payment per 1000 inhabitants and working day and subsidised cost per 1000 inhabitants and working day associated with the introduction of generic substitution were analysed. Expenditure was expressed in Swedish krona, SEK (SEK 1=US$ 0.14/euro 0.11, 7 July 2006). The Swedish Consumer Price Index was used to inflation-adjust expenditures with 2004 as base. The introduction of generic substitution was associated with a significant change in slope for patient co-payment in both all prescribed pharmaceuticals and pharmaceuticals on regular prescriptions (p<0.005) for Sweden in total. The slope shifted direction from a slight increase before the reform into a decline after the reform was implemented. This was also found for the average slope of patient co-payment for all county councils (p<0.0001). The introduction of generic substitution was associated with a statistically significant shift in slope for subsidised cost for Sweden in total (p<0.001). The slope shifted from a monthly increase before October 2002 to a monthly decline for all prescribed pharmaceuticals afterwards. Similar results were found for the average slope of subsidised cost for all county councils both for all prescribed pharmaceuticals and pharmaceuticals on regular prescriptions (p<0.0001). The introduction of generic substitution was associated with a shift in trend from an increase into a decrease both for patients' and society's expenditures. This suggests that generic substitution has contributed to a reduction in the growth of pharmaceutical expenditure.

  • Influence of mandatory generic substitution on pharmaceutical sales patterns: a national study over five years
  • 2008
  • Ingår i: BMC Health Services Research. - : Springer Science and Business Media LLC. - 1472-6963. ; 8:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND:Mandatory generic substitution was introduced in Sweden in October 2002 in order to try to curb escalating pharmaceutical expenditure. The aim of this study was to investigate how sales patterns for substitutable and non-substitutable pharmaceuticals have developed since the introduction of mandatory generic substitution; furthermore, to compare sales patterns in different groups of the population, based on patients' age and gender. METHODS:Five therapeutic groups comprising both substitutable and non-substitutable pharmaceuticals were included. The study period was from January 2000 to June 2005. National sales data were used, covering volumes of dispensed prescription medicines (expressed in defined daily doses per 1000 inhabitants and day) of each pharmacological substance in the therapeutic groups for each age and gender group. Sales patterns for substitutable and non-substitutable pharmaceuticals were compared using a descriptive approach. RESULTS:In most therapeutic groups there has been an increase in the volumes of substitutable pharmaceuticals sold since the introduction of the reform, ranging from one third to three times the initial volume; whereas the volumes of non-substitutable pharmaceuticals have levelled out or declined. There were few gender differences in sales patterns of substitutable and non-substitutable drugs. In three therapeutic groups, sales patterns differed across different age groups, and there was a tendency for volumes of recently introduced non-substitutable pharmaceuticals to be proportionally higher in the youngest age groups. CONCLUSION:Since the introduction of the reform, there has been a proportionally larger increase in sales of substitutable pharmaceuticals compared with sales of non-substitutable pharmaceuticals. This indicates that the reform might have contributed to larger sales of less expensive pharmaceuticals.

    • BACKGROUND: Early discontinuation of anti-depressant treatment is common. This study analysed whether socio-economic factors influence early discontinuation among new anti-depressant users aged 20-34 years. METHODS: Our study population included all Swedes aged 20-34 years who purchased anti-depressants in 2006 and had not purchased such drugs in the preceding 6 months (n=25003). We obtained prescription data from the Swedish Prescribed Drug Register. Information about demographic and socio-economic factors (country of birth, marital status, household size, education level, occupation, income and social assistance) was collected from Statistics Sweden by record linkage. We defined early discontinuation as filling only one anti-depressant prescription within a 6-month period. We used multiple logistic regression analysis to analyse the socio-economic factors associated with early discontinuation. RESULTS: We identified 6536 individuals (26.1%) as early discontinuers. Early discontinuation was less common among women [odds ratio (OR)=0.82; 95% confidence intervals (CI) 0.75-0.87] and in those with at least two years of higher education (OR=0.71; 95% CI 0.61-0.83), whereas it was more common among those born outside Sweden (OR=1.76; 95% CI 1.48-2.10) and those who received social assistance (OR=1.26; 95% CI 1.11-1.44). Compared with selective serotonin re-uptake inhibitors, SSRI, early discontinuation was more common among individuals who started treatment with a tri-cyclic anti-depressant, TCA, (OR=2.58; 95% CI 2.24-2.98) or an anti-depressant other than SSRIs, TCAs or selective serotonin-norepinephrine re-uptake inhibitors/norepinephrine (noradrenaline) re-uptake inhibitors (OR=2.90; 95% CI 2.05-4.10). CONCLUSION: Early discontinuation occurred more commonly among social assistance recipients and those with immigrant background, suggesting that those groups might require greater support when initiating anti-depressant therapy.

    • OBJECTIVE: To investigate the dental health of Swedish children and adolescents with reference to age, gender and residence.MATERIAL AND METHODS: Electronic dental records from 300,988 3-19-year-olds in one Swedish region were derived in a cross-sectional study in years 2007-2009. The DMFT system was used. Age was categorized into 3-6/7-9/10-12/13-15/16-17/18-19-year-olds and residence into 'metropolitan', 'urban' and 'rural' areas. ANOVA, generalized linear regression models and Fisher's exact test were used.RESULTS: Among 7-9-year-old children, nine out of 10 were free from fillings and manifest caries, while for 18-19-year-olds; this proportion was one third. Girls (18-19-year-olds) had a significantly lower risk of caries compared to boys of the same age, RR for the DT index = 0.83 (95% CI = 0.81-0.85). This pattern was reversed in 7-12-year-old children. Children and adolescents in metropolitan and urban areas had significantly more caries than subjects in rural areas, for instance the RR for the DT index in metropolitan 7-9-year-olds was 2.26 (95% CI = 2.11-2.42) compared to their rural counterparts.CONCLUSIONS: In the permanent dentition, the overall pattern revealed that girls ≤ 12 years had a higher risk of caries, while adolescent girls had a lower risk of caries, both compared with boys of corresponding ages. Living in an urban or metropolitan area entailed a higher risk of caries than living in a rural area. A greater occurrence of dental caries in adolescents than in children was confirmed. The findings should have implications for planning and evaluation of oral health promotion and disease prevention activities.

    • The study aimed to explore associations between multiple socioeconomic factors and dental caries experience in Swedish children and adolescents (3-19 years old). Electronic dental records from 300,988, in a Swedish region (97.3% coverage) were collected using the DMFT indices (decayed, missing, filled teeth: dependent variables). Socioeconomic status (SES) data (ethnicity, wealth, parental education, and employment) for individuals, parents, and families were obtained from official registers. Principal component analysis was used to explore SES data. Scores based on the first factor were used as an independent aggregated socioeconomic variable in logistic regression analyses. Dental caries experience was low in the participants: 16% in 3- to 6-year-olds (deft index: decayed, extracted, filled teeth) and 47% in 7- to 19-year-olds (DFT index). Both separate and aggregated socioeconomic variables were consistently associated with the dental caries experience irrespective of the caries index used: the crude odds ratio (OR) for having at least 1 caries lesion in 3- to 6-year-olds (deft index) in the lowest SES quintile was 3.26 (95% confidence interval [CI] 3.09-3.43) and in ≥7-year-olds (DFT index) OR 1.80 (95% CI 1.75-1.84) compared with children in the 4 higher SES quintiles. Overall, associations were stronger in the primary dentition than in the permanent dentition. Large SES models contributed more to explaining the caries experience than slim models including fewer SES indicators. In conclusion, socioeconomic factors were consistently associated with dental caries experience in the children and adolescents both as single factors and as multiple factors combined in an index. Socioeconomic inequalities had stronger associations to caries experience in young children than in older children and adolescents.

  • 2023
  • Ingår i: Journal of Periodontology. - 0022-3492 .- 1943-3670. ; 94:11, s. 1324-37

    • Background: The aim of this study was to investigate the association between periodontitis and four single nucleotide polymorphisms (SNPs) in genes involved in epigenetic regulation of DNA, and between these same SNPs and tooth loss, high-sensitivity C-reactive protein (hs-CRP), and glycated hemoglobin (HbA1c) levels. Methods: We included participants with periodontal examination (n = 3633, aged: 40-93 years) from the Tromsø Study seventh survey (2015-2016), Norway. Periodontitis was defined according to the 2017 AAP/EFP classification system as no periodontitis, grades A, B, or C. Salivary DNA was extracted and genotyping was performed to investigate four SNPs (rs2288349, rs35474715, rs34023346, and rs10010325) in the sequence of the genes DNMT1, IDH2, TET1, and TET2. Association between SNPs and periodontitis was analyzed by logistic regression adjusted for age, sex, and smoking. Subgroup analyses on participants aged 40-49 years were performed. Results: In participants aged 40-49 years, homozygous carriage of minor A-allele of rs2288349 (DNMT1) was associated with decreased susceptibility to periodontitis (grade A: odds ratio [OR] 0.55; p = 0.014: grade B/C OR 0.48; p = 0.004). The minor A-allele of rs10010325 (TET2) was associated with increased susceptibility to periodontitis (grade A OR 1.69; p = 0.035: grade B/C OR 1.90; p = 0.014). In the entire sample, homozygous carriage of the G-allele of rs35474715 (IDH2) was associated with having ≤24 teeth (OR 1.31; p = 0.018). Homozygous carriage of the A-allele of TET2 was associated with hs-CRP≥3 mg/L (OR 1.37; p = 0.025) and HbA1c≥6.5% (OR 1.62; p = 0.028). Conclusions: In this Norwegian population, there were associations between polymorphism in genes related to DNA methylation and periodontitis, tooth loss, low-grade inflammation, and hyperglycemia.

    • The aim of this study was to investigate which principal human cytochrome P450 (CYP450) enzymes are affected by artemisinin and to what degree the artemisinin derivatives differ with respect to their respective induction and inhibition capacity. Seventy-five healthy adults were randomized to receive therapeutic oral doses of artemisinin, dihydroartemisinin, arteether, artemether or artesunate for 5 days (days 1–5). A six-drug cocktail consisting of caffeine, coumarin, mephenytoin, metoprolol, chlorzoxazone and midazolam was administered orally on days −6, 1, 5 and 10 to assess the activities of CYP1A2, CYP2A6, CYP2C19, CYP2D6, CYP2E1 and CYP3A, respectively. Four-hour plasma concentrations of parent drugs and corresponding metabolites and 7-hydroxycoumarin urine concentrations were quantified by liquid chromatography-tandem mass spectrometry. The 1-hydroxymidazolam/midazolam 4-h plasma concentration ratio (CYP3A) was increased on day 5 by artemisinin [2.66-fold (98.75% CI: 2.10–3.36)], artemether [1.54 (1.14–2.09)] and dihydroartemisinin [1.25 (1.06–1.47)] compared with day −6. The S-4'-hydroxymephenytoin/S-mephenytoin ratio (CYP2C19) was increased on day 5 by artemisinin [1.69 (1.47–1.94)] and arteether [1.33 (1.15–1.55)] compared with day −6. The paraxanthine/caffeine ratio (CYP1A2) was decreased on day 1 after administration of artemisinin [0.27 (0.18–0.39)], arteether [0.70 (0.55–0.89)] and dihydroartemisinin [0.73 (0.59–0.90)] compared with day −6. The α-hydroxymetoprolol/metoprolol ratio (CYP2D6) was lower on day 1 compared with day −6 in the artemisinin [0.82 (0.70–0.96)] and dihydroartemisinin [0.83 (0.71–0.96)] groups, respectively. In the artemisinin-treated subjects this decrease was followed by a 1.34-fold (1.14–1.58) increase from day 1 to day 5. These results show that intake of artemisinin antimalarials affect the activities of several principal human drug metabolizing CYP450 enzymes. Even though not significant in all treatment groups, changes in the individual metrics were of the same direction for all the artemisinin drugs, suggesting a class effect that needs to be considered in the development of new artemisinin derivatives and combination treatments of malaria.

    • Rapid diagnostic test (RDT) is an important tool for parasite-based malaria diagnosis. High specificity of RDTs to distinguish an active Plasmodium falciparum infection from residual antigens from a previous infection is crucial in endemic areas where residents are repeatedly exposed to malaria. The efficiency of two RDTs based on histidine-rich protein 2 (HRP2) and lactate dehydrogenase (LDH) antigens were studied and compared with two microscopy techniques (Giemsa and acridine orange-stained blood smears) and real-time polymerase chain reaction (PCR) for assessment of initial clearance and detection of recurrent P. falciparum infections after artemisinin-based combination therapy (ACT) in a moderately high endemic area of rural Tanzania.

  • Automated respiratory rate counter to assess children for symptoms of pneumonia: Protocol for cross-sectional usability and acceptability studies in Ethiopia and Nepal
  • 2020
  • Ingår i: JMIR Research Protocols. - : JMIR Publications Inc.. - 1929-0748. ; 9:3
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Manually counting a child's respiratory rate (RR) for 60 seconds using an acute respiratory infection timer is the World Health Organization (WHO) recommended method for detecting fast breathing as a sign of pneumonia. However, counting the RR is challenging and misclassification of an observed rate is common, often leading to inappropriate treatment. To address this gap, the acute respiratory infection diagnostic aid (ARIDA) project was initiated in response to a call for better pneumonia diagnostic aids and aimed to identify and assess automated RR counters for classifying fast breathing pneumonia when used by front-line health workers in resource-limited community settings and health facilities. The Children's Automated Respiration Monitor (ChARM), an automated RR diagnostic aid using accelerometer technology developed by Koninklijke Philips NV, and the Rad-G, a multimodal RR diagnostic and pulse oximeter developed by Masimo, were the two devices tested in these studies conducted in the Southern Nations, Nationalities, and Peoples' Region in Ethiopia and in the Karnali region in Nepal. Objective: In these studies, we aimed to understand the usability of two new automated RR diagnostic aids for community health workers (CHWs; health extension workers [Ethiopia] and female community health volunteers [Nepal]) and their acceptability to CHWs in Ethiopia and Nepal, first-level health facility workers (FLHFWs) in Ethiopia only, and caregivers in both Ethiopia and Nepal. Methods: This was a prospective, cross-sectional study with a mixed methods design. CHWs and FLHFWs were trained to use both devices and provided with refresher training on all WHO requirements to assess fast breathing. Immediately after training, CHWs were observed using ARIDA on two children. Routine pneumonia case management consultations for children aged 5 years and younger and the device used for these consultations between the first and second consultations were recorded by CHWs in their patient log books. CHWs were observed a second time after 2 months. Semistructured interviews were also conducted with CHWs, FLHFWs, and caregivers. The proportion of consultations with children aged 5 years and younger where CHWs using an ARIDA and adhered to all WHO requirements to assess fast breathing and device manufacturer instructions for use after 2 months will be calculated. Qualitative data from semistructured interviews will be analyzed using a thematic framework approach. Results: The ARIDA project was funded in November 2015, and data collection was conducted between April and December 2018. Data analysis is currently under way and the first results are expected to be submitted for publication in 2020. Conclusions: This is the first time the usability and acceptability of automated RR counters in low-resource settings have been evaluated. Outcomes will be relevant for policy makers and are important for future research of this new class of diagnostic aids for the management of children with suspected pneumonia. © Kevin Nicholas Baker, Alice Maurel, Charlotte Ward, Dawit Getachew, Tedila Habte, Cindy McWhorter, Paul LaBarre, Jonas Karlström, Max Petzold, Karin Källander.

    • BACKGROUND: Pneumonia is one of the leading causes of death in children aged under 5 years in both sub-Saharan Africa and Southeast Asia. The current diagnostic criterion for pneumonia is based on the increased respiratory rate (RR) in children with cough or difficulty breathing. Low oxygen saturation, measured using pulse oximeters, is indicative of severe pneumonia. Health workers often find it difficult to accurately count the number of breaths, and the current RR counting devices are often difficult to use or unavailable. Nonetheless, improved counting devices and low-cost pulse oximeters are now available on the market. OBJECTIVE: The objective of our study was to identify the most accurate, usable, and acceptable devices for the diagnosis of pneumonia symptoms by community health workers and first-level health facility workers or frontline health workers in resource-poor settings. METHODS: This was a multicenter, prospective, two-stage, observational study to assess the performance and usability or acceptability of 9 potential diagnostic devices when used to detect symptoms of pneumonia in the hands of frontline health workers. Notably, 188 possible devices were ranked and scored, tested for suitability in a laboratory, and 5 pulse oximeters and 4 RR timers were evaluated for usability and performance by frontline health workers in hospital, health facility, and community settings. The performance was evaluated against 2 references over 3 months in Cambodia, Ethiopia, South Sudan, and Uganda. Furthermore, acceptability and usability was subsequently evaluated using both qualitative and quantitative methodologies in routine practice, over 3 months, in the 4 countries. RESULTS: This project was funded in 2014, and data collection has been completed. Data analysis is currently under way, and the first results are expected to be submitted for publication in 2018. CONCLUSIONS: This is the first large-scale evaluation of tools to detect symptoms of pneumonia at the community level. In addition, selecting an appropriate reference standard against which the devices were measured was challenging given the lack of existing standards and differences of opinions among experts. The findings from this study will help create a standardized and validated protocol for future studies and support further comparative testing of diagnostic devices in these settings.

  • Performance of five pulse oximeters to detect hypoxaemia as an indicator of severe illness in children under five by frontline health workers in low resource settings- A prospective, multicentre, single-blinded, trial in Cambodia, Ethiopia, South Sudan, and Uganda
  • 2021

  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Low blood oxygen saturation (SpO2), or hypoxaemia, is an indicator of severe illness in children. Pulse oximetry is a globally accepted, non-invasive method to identify hypoxaemia, but rarely available outside higher-level facilities in resource-constrained countries. This study aims to evaluate the performance of different types of pulse oximeters amongst frontline health workers in Cambodia, Ethiopia, South Sudan, and Uganda. Methods: Five pulse oximeters (POx) which passed laboratory testing, out of an initial 32 potential pulse oximeters, were evaluated by frontline health workers for performance, defined as agreement between the SpO2 measurements of the test device and the reference standard. The study protocol is registered with the Australia New Zealand Clinical Trials Registry (Ref: ACTRrn12615000348550). Findings: Two finger-tip pulse oximeters (Contec and Devon), two handheld pulse oximeters (Lifebox and Utech), and one phone pulse oximeter (Masimo) passed the laboratory testing. They were evaluated for performance on 1,313 children under five years old by 207 frontline health workers between February and May 2015. Phone and handheld pulse oximeters had greater overall agreement with the reference standard (56%; 95% CI 0.52 - 0.60 to 68%; 95% CI 0.65 - 0.71) than the finger-tip POx (31%; 95% CI 0.26 to 0.36 and 47%; 95% CI 0.42 to 0.52). Fingertip POx performance was substantially lower in the 0-2 month olds; having just 17% and 25% agreement. The finger-tip devices more often underreported SpO2 readings (mean difference -7.9%; 95%CI -8.6,-7.2 and -3.9%; 95%CI -4.4,-3.4), and therefore over diagnosed hypoxaemia in the children assessed. Interpretation: While the Masimo phone pulse oximeter performed best, all handheld POx with age-specific probes performed well in the hands of frontline health workers, further highlighting their suitability as a screening tool of severe illness. The poor performance of the fingertip POx suggests they should not be used in children under five by frontline health workers. It is essential that POx are performance tested on children in routine settings (in vivo), not only in laboratories or controlled settings (in vitro), before being introduced at scale.

  • Performance of Four Respiratory Rate Counters to Support Community Health Workers to Detect the Symptoms of Pneumonia in Children in Low Resource Settings: A Prospective, Multicentre, Hospital-Based, Single-Blinded, Comparative Trial
  • 2019
  • Ingår i: EClinicalMedicine. - : Elsevier BV. - 2589-5370.
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Pneumonia is one of the leading causes of death in children under-five globally. The current diagnostic criteria for pneumonia are based on increased respiratory rate (RR) or chest in-drawing in children with cough and/or difficulty breathing. Accurately counting RR is difficult for community health workers (CHWs). Current RR counting devices are frequently inadequate or unavailable. This study analysed the performance of improved RR timers for detection of pneumonia symptoms in low-resource settings. Methods: Four RR timers were evaluated on 454 children, aged from 0 to 59 months with cough and/or difficulty breathing, over three months, by CHWs in hospital settings in Cambodia, Ethiopia, South Sudan and Uganda. The devices were the Mark Two ARI timer (MK2 ARI), counting beads with ARI timer, Rrate Android phone and the Respirometer feature phone applications. Performance was evaluated for agreement with an automated RR reference standard (Masimo Root patient monitoring and connectivity platform with ISA CO2 capnography). This study is registered with ANZCTR [ACTRN12615000348550]. Findings: While most CHWs managed to achieve a RR count with the four devices, the agreement was low for all; the mean difference of RR measurements from the reference standard for the four devices ranged from 0.5 (95% C.I. − 2.2 to 1.2) for the respirometer to 5.5 (95% C.I. 3.2 to 7.8) for Rrate. Performance was consistently lower for young infants (0 to < 2 months) than for older children (2 to ≤ 59 months). Agreement of RR classification into fast and normal breathing was moderate across all four devices, with Cohen's Kappa statistics ranging from 0.41 (SE 0.04) to 0.49 (SE 0.05). Interpretation: None of the four devices evaluated performed well based on agreement with the reference standard. The ARI timer currently recommended for use by CHWs should only be replaced by more expensive, equally performing, automated RR devices when aspects such as usability and duration of the device significantly improve the patient-provider experience.

  • Healthcare Access and Quality Index based on mortality from causes amenable to personal health care in 195 countries and territories, 1990-2015: a novel analysis from the Global Burden of Disease Study 2015
  • 2017
  • Ingår i: Lancet. - : Elsevier BV. - 0140-6736. ; 390:10091, s. 231-266
  • Tidskriftsartikel (refereegranskat)abstract
    • Background National levels of personal health-care access and quality can be approximated by measuring mortality rates from causes that should not be fatal in the presence of effective medical care (ie, amenable mortality). Previous analyses of mortality amenable to health care only focused on high-income countries and faced several methodological challenges. In the present analysis, we use the highly standardised cause of death and risk factor estimates generated through the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) to improve and expand the quantification of personal health-care access and quality for 195 countries and territories from 1990 to 2015. Methods We mapped the most widely used list of causes amenable to personal health care developed by Nolte and McKee to 32 GBD causes. We accounted for variations in cause of death certification and misclassifications through the extensive data standardisation processes and redistribution algorithms developed for GBD. To isolate the effects of personal health-care access and quality, we risk-standardised cause-specific mortality rates for each geography-year by removing the joint effects of local environmental and behavioural risks, and adding back the global levels of risk exposure as estimated for GBD 2015. We employed principal component analysis to create a single, interpretable summary measure-the Healthcare Quality and Access (HAQ) Index-on a scale of 0 to 100. The HAQ Index showed strong convergence validity as compared with other health-system indicators, including health expenditure per capita (r= 0.88), an index of 11 universal health coverage interventions (r= 0.83), and human resources for health per 1000 (r= 0.77). We used free disposal hull analysis with bootstrapping to produce a frontier based on the relationship between the HAQ Index and the Socio-demographic Index (SDI), a measure of overall development consisting of income per capita, average years of education, and total fertility rates. This frontier allowed us to better quantify the maximum levels of personal health-care access and quality achieved across the development spectrum, and pinpoint geographies where gaps between observed and potential levels have narrowed or widened over time. Findings Between 1990 and 2015, nearly all countries and territories saw their HAQ Index values improve; nonetheless, the difference between the highest and lowest observed HAQ Index was larger in 2015 than in 1990, ranging from 28.6 to 94.6. Of 195 geographies, 167 had statistically significant increases in HAQ Index levels since 1990, with South Korea, Turkey, Peru, China, and the Maldives recording among the largest gains by 2015. Performance on the HAQ Index and individual causes showed distinct patterns by region and level of development, yet substantial heterogeneities emerged for several causes, including cancers in highest-SDI countries; chronic kidney disease, diabetes, diarrhoeal diseases, and lower respiratory infections among middle-SDI countries; and measles and tetanus among lowest-SDI countries. While the global HAQ Index average rose from 40.7 (95% uncertainty interval, 39.0-42.8) in 1990 to 53.7 (52.2-55.4) in 2015, far less progress occurred in narrowing the gap between observed HAQ Index values and maximum levels achieved; at the global level, the difference between the observed and frontier HAQ Index only decreased from 21.2 in 1990 to 20.1 in 2015. If every country and territory had achieved the highest observed HAQ Index by their corresponding level of SDI, the global average would have been 73.8 in 2015. Several countries, particularly in eastern and western sub-Saharan Africa, reached HAQ Index values similar to or beyond their development levels, whereas others, namely in southern sub-Saharan Africa, the Middle East, and south Asia, lagged behind what geographies of similar development attained between 1990 and 2015. Interpretation This novel extension of the GBD Study shows the untapped potential for personal health-care access and quality improvement across the development spectrum. Amid substantive advances in personal health care at the national level, heterogeneous patterns for individual causes in given countries or territories suggest that few places have consistently achieved optimal health-care access and quality across health-system functions and therapeutic areas. This is especially evident in middle-SDI countries, many of which have recently undergone or are currently experiencing epidemiological transitions. The HAQ Index, if paired with other measures of health-systemcharacteristics such as intervention coverage, could provide a robust avenue for tracking progress on universal health coverage and identifying local priorities for strengthening personal health-care quality and access throughout the world.

  • Acute coronary syndrome in octogenarians: association between percutaneous coronary intervention and long-term mortality
  • 2015
  • Ingår i: Clinical Interventions in Aging. - : Informa UK Limited. - 1178-1998. ; 10, s. 1547-1553
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim: Evidence of improved survival after use of percutaneous coronary intervention (PCI) in elderly patients with acute coronary syndrome (ACS) is limited. We assessed the association between PCI and long-term mortality in octogenarians with ACS. Methods and results: We followed 353 consecutive patients aged >= 80 years hospitalized with ACS during 2006-2007. Among them, 182 were treated with PCI, whereas 171 were not. PCI-treated patients were younger and more often male, and had less stroke and dependency in activities of daily living, but there were no significant differences in occurrence of diabetes mellitus, chronic obstructive pulmonary disease, hypertension, and uncured malignancies between the two groups. The association between PCI and all-cause mortality was assessed in the overall cohort and a 1: 1 matched cohort based on propensity score (PS). In overall cohort, 5-year all-cause mortality was 46.2% and 89.5% in the PCI and non-PCI groups, respectively. Cox regression analysis in overall cohort by adjustment for ten baseline variables showed statistically significant association between PCI and reduced long-term mortality (P < 0.001, hazard ratio 0.4, 95% confidence interval [CI] 0.2-0.5). In propensity-matched cohort, 5-year all-cause mortality was 54.9% and 83.1% in the PCI and non-PCI groups, respectively. Kaplan-Meier survival curves and log rank test showed significantly improved mean survival rates (P=0.001): 48 months (95% CI 41-54) for PCI-treated patients versus 35 months (95% CI 29-42) for non-PCI-treated patients. Furthermore, by performing Cox regression analysis, PCI was still associated with reduced long-term mortality (P=0.029, hazard ratio 0.5, 95% CI 0.3-0.9) after adjustment for PS and confounders: age, male sex, cognitive deterioration, uncured malignancies, left ventricular ejection fraction <45%, estimated glomerular filtration rate < 35 mL/min, ST-segment elevation myocardial infarction, mitral regurgitation, and medication at discharge with clopidogrel and statins. Conclusion: In octogenarians with ACS, PCI was associated with improved survival from all-cause death over 5 years of follow-up.

  • Does the target dose of neurohormonal blockade matter for outcome in Systolic heart failure in octogenarians?
  • 2015
  • Ingår i: International Journal of Cardiology. - : Elsevier BV. - 0167-5273. ; 187, s. 666-672
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: In elderly patients with chronic heart failure (CHF), a gap exists between widespread use of lower doses of angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin-receptor blockers (ARBs) and beta-blockers (BBs) and guideline recommendations. Therefore, the aim of the present study was to investigate whether patients receiving >= 50% target dose outperform those receiving <50% target dose, despite maximum up-titration, and whether the target dose outperforms all other doses. Methods and Results: Patients (n=185) aged >= 80 years with CHF and left ventricular ejection fraction >= 40% referred (between January 2000 and January 2008) to two CHF outpatient clinics at two university hospitals, were included and retrospectively studied. Of the study population, 53% received the target dose of ACEIs/ARBs, whereas 26% received <50% of the target dose. Half received <50% of the target dose of BBs and 21% received the target dose. After >= 5 years of follow-up, all-cause mortality was 76.8%. Patients who received the target dose of ACEIs/ARBs had higher survival rates from all-cause mortality than those receiving <50% of target dose (HR = 0.6, 95% CI 0.4-0.9, P = 0.033), but those receiving >= 50% of target dose did not statistically differ from those who achieved target dose. This dose-survival relationship was not the case for BBs. Conclusions: Target dose of ACEIs/ARBs is associated with reduced all-cause five-year mortality in very old patients with systolic heart failure, despite that this was achievable in only about half of the patients. However, the clinical outcome of BB therapy is independent of BB dose when the target heart rate is achieved. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

    • A substantial part of deaths and readmissions in octogenarians with acute coronary syndrome (ACS) is assumed to be of non-cardiovascular causes. However, limited data on cause-specific long-term mortality and hospital readmissions are available. This study was aimed to investigate 5-year cause-specific deaths and re-hospitalizations as well as their prognostic predictors among octogenarians with ACS managed with percutaneous coronary intervention (PCI).A total of 181 octogenarians managed with PCI on ACS indication during 2006-2007 at Sahlgrenska University Hospital were included. The time-period was chosen to allow a follow-up period of five years.All-cause 5-year mortality was 46%. Approximately 70% of deaths were cardiovascular. All-cause hospital readmissions were 71%. The majority of readmissions were due to non-cardiovascular diseases, 61% of all readmissions. Cox proportional-hazard regression analyses for cardiovascular mortality identified female sex and culprit lesion in left coronary arteries as independent predictors. Negative binomial regression models showed female sex and complications during index hospitalization as independent predictors of increased cardiovascular re-hospitalizations and prior smoking as independent predictor of increased non-cardiovascular re-hospitalizations.In an octogenarian cohort presented with ACS treated with PCI, cardiovascular diseases were the main causes of deaths, whereas non-cardiovascular diseases were the main causes of re-hospitalizations.

    • The majority of patients with acute coronary syndrome (ACS) are elderly. Limited evidence makes decision-making on the use of percutaneous coronary intervention (PCI) mainly empirical. Old age is one risk factor, but other factors than age may have an impact on mortality as well. Therefore, we investigated predictors of long-term all-cause mortality among octogenarians who have undergone PCI due to ACS. A total of 182 patients ≥. 80 years who underwent PCI during 2006-2007 at Sahlgrenska University Hospital were studied consecutively from recorded clinical data. All-cause five-year mortality of follow-up was 46.2%. Mean age was 83.7. ±. 2.8, 62% were male, 76% were in sinus rhythm, and 42% had left ventricular ejection fraction. < 45%. Indications for PCI were STEMI (52%), NSTEMI (36%) and unstable angina (11%). Multivariate analysis in two steps identified atrial fibrillation, moderate tricuspid valve regurgitation, moderate mitral valve regurgitation, dependency in ADL and eGFR. ≤. 30. ml/min at the first step and moderate mitral valve regurgitation, atrial fibrillation and eGFR. ≤. 30 ml/min at the last step, as independent predictors of all-cause mortality. Kaplan Meier analysis of positive parameters from both steps of multivariate analysis showed high significant difference in survival between patients having these parameters and those who were free from these parameters, with worst prognosis in patients with accumulation of these parameters. Accordingly, we have, in an octogenarian patient cohort who suffered from ACS, undergone PCI in daily clinical practice, identified five prognostic predictors for all-cause death after five years' follow-up.

  • Prognostic impact of heart rate in elderly with systolic heart failure and concomitant atrial fibrillation
  • 2017
  • Ingår i: Scandinavian Cardiovascular Journal. - : Informa UK Limited. - 1401-7431 .- 1651-2006. ; 51:4, s. 190-196
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: The present study aimed to investigate the impact of resting heart rate (HR) on 5-year all-cause mortality in patients 80 years with heart failure (HF) with reduced ejection fraction (HFrEF) and concomitant atrial fibrillation (AF) after optimal up-titration of beta-blockers (BBs).Methods: Patients (n=185) aged 80 years with HF and left ventricular ejection fraction 40% were included between January 2000 and January 2008 from two university hospitals, Sahlgrenska and ostra and retrospectively studied from January 2 to May 30, 2013. Up-titrations of guideline recommended medications were performed at HF outpatient clinics.Results: Of whole study population, 54% (n=100) had AF. After optimal up-titration of BBs and angiotensin converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs), mean HR in patients with AF was 7315 beats/minute (bpm), 36% had resting HR65 bpm. Five-year all-cause mortality among patients with AF was significantly lower in patients with HR65 bpm (63%) compared to HR>65 (80%). Cox proportional-hazard regression analysis adjusted for clinically important baseline variables and doses of ACEIs/ARBs and BBs demonstrated resting HR65 bpm as an independent predictor of improved survival compared to resting HR>65 bpm (HR 0.3, 95%CI 0.1-0.7, P 0.005).Discussion: In octogenarians with HFrEF and concomitant AF, lowering resting HR to levels as low as HR65 bpm was still associated with improved survival from all-cause mortality. Our data indicate that mortality in AF became comparable to SR when patients were on maximally up-titrated beta-blocker doses with HR as low as 75 bpm.

  • Improved dengue fever prevention through innovative intervention methods in the city of Salto, Uruguay
  • 2015
  • Ingår i: Transactions of the Royal Society of Tropical Medicine and Hygiene. - : Oxford University Press (OUP). - 0035-9203 .- 1878-3503. ; 109:2, s. 134-142
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Uruguay is located at the southern border of Aedes aegypti distribution on the South American sub-continent. The reported dengue cases in the country are all imported from surrounding countries. One of the cities at higher risk of local dengue transmission is Salto, a border city with heavy traffic from dengue endemic areas. Methods: We completed an intervention study using a cluster randomized trial design in 20 randomly selected 'clusters' in Salto. The clusters were located in neighborhoods of differing geography and economic, cultural and social aspects. Results: Entomological surveys were carried out to measure the impact of the intervention on vector densities. Through participatory processes of all stakeholders, an appropriate ecosystem management intervention was defined. Residents collected the abundant small water holding containers and the Ministry of Public Health and the Municipality of Salto were responsible for collecting and eliminating them. Additional vector breeding places were large water tanks; they were either altered so that they could not hold water any more or covered so that oviposition by mosquitoes could not take place. Conclusions: The response from the community and national programme managers was encouraging. The intervention evidenced opportunities for cost savings and reducing dengue vector densities (although not to statistically significant levels). The observed low vector density limits the potential reduction due to the intervention. A larger sample size is needed to obtain a statistically significant difference.
