- BACKGROUND: A novel approach to determine the effect of a treatment is to calculate the delay of event, which estimates the gain of event-free time. The aim of this study was to estimate gains in event-free time for stroke or systemic embolism, death, bleeding events, and the composite of these events, in patients with atrial fibrillation randomized to either warfarin or apixaban in the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation trial (ARISTOTLE).DESIGN: The ARISTOTLE study was a randomized double-blind trial comparing apixaban with warfarin.METHODS: Laplace regression was used to estimate the delay in time to the outcomes between the apixaban and the warfarin group in 6, 12, 18 and 22 months of follow-up.RESULTS: The gain in event-free time for apixaban versus warfarin was 181 (95% confidence interval 76 to 287) days for stroke or systemic embolism and 55 (-4 to 114) days for death after 22 months of follow-up. The corresponding gains in event-free times for major and intracranial bleeding were 206 (130 to 281) and 392 (249 to 535) days, respectively. The overall gain for the composite of all these events was a gain of 116 (60 to 171) days.CONCLUSIONS: In patients with atrial fibrillation, 22 months of treatment with apixaban, as compared with warfarin, provided gains of approximately 6 months in event-free time for stroke or systemic embolism, 7 months for major bleeding and 13 months for intracranial bleeding.

Clean work, the pursuit of increased adherence to hand hygiene routines : a descriptive study
- 2022

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Healthcare-associated infections (HAI) are a problem in health care worldwide. In Sweden 7-8% of all patients treated in hospital suffer from an adverse event of varying severity, of which approximately 60,000 from a HAI. Proper hand hygiene is considered the single most important measure to reduce HAI. Despite the importance, adherence to correct hand hygiene routines are lacking among healthcare workers (HCWs). The World Health Organizations (WHO) multimodal promotion strategy promotes areas that need to be addressed in order to change the behaviour of individual HCWs to optimise adherence to hand hygiene and to improve patient safety. These areas include feedback, education, reminders at the workplace and institutional safety climate. The overall aim of this study was to examine the possibility of adherence to hand hygiene routines and to explore factors that might influence the HCWs adherence. The study used a descriptive research design made through qualitative method, with focus group interviews, and quantitative method, using a questionnaire survey. Eight focus group interviews were conducted with assistant nurses (n=18), nurses (n=15) and physicians (n=5) and analysed with abductive qualitative content analysis. The questionnaire survey was answered by nurses (n=84) and nursing students in their first semester (n=71) and last semester (n=46) and the data was statistically analysed.The main findings show that there are barriers to hand hygiene adherence and measures to improve these. HCWs highlighted discrepancies regarding how the organisation was supposed to give feedback and how it actually was at the workplace and expressed needs for more direct feedback to improve adherence. The study also found that hygienic knowledge gaps exists among nurses and nursing students regarding causes of HAI and how the risk of contamination of patients and HCWs can be minimized among others. Students at the beginning of the education had a lower level of knowledge than last semester students and registered nurses. The last semester students tended to have the highest level of hand hygiene knowledge. In conclusion, the key areas presented by WHO’s multimodal promotion strategy to improve adherence all lack the appropriate measures, in some extent. The use of an electronic reminder system could give the means to improve a behaviour as long as the individual integrity is protected and development of curriculums for nursing students and continuing education of nurses is needed to further develop and maintaining knowledge.

- Background:Healthcare-associated infections (HCAIs) have a large negative impact onmorbidity, mortality, and quality of life. Approximately 9% of all patients hospitalized inSweden suffer from HCAI. Hand hygiene plays a key role and is considered the single mostimportant measure to reduce HCAI. The hospital organization works actively to reduceHCAI. Implementing electronic systems to remind and/or notify healthcare workers raisesawareness of and adherence to hand hygiene. However, there is a paucity of studiesaddressing individuals’ perceptions of having such a system and how the organizationworks.Aim:To investigate healthcare workers’ perceptions of infection prevention in thehealthcare organization and perceptions and acceptance of an electronic reminder systemthat encourages good hand hygiene.Methods:Qualitative descriptive design with data collected in eight focus group inter-views including assistant nurses, nurses, and physicians (N¼38). Content analysis wasapplied and data were related to the Theory of Planned Behaviour.Findings:Healthcare workers perceive lack of feedback from the hospital organizationand are positive towards an electronic reminder system to increase adherence to handhygiene. The electronic reminder system should not register data at an individual levelsince it could be used as an instrument for control by the management that could bestressful for staff.Conclusion:In general, there is positive acceptance of the electronic reminder system,and the respondents perceived it as having the ability to change behaviour. However, theconcept has to be further developed to protect the individual’s integrity and needs to beused with feedback on a group level

- Background: Chronic pain and mental disorders are common reasons for long term sick leave. The study objective was to evaluate the efficacy of a multidisciplinary assessment and treatment program including acceptance and commitment therapy (TEAM) and stand-alone acceptance and commitment therapy (ACT), compared with treatment as usual (Control) on health outcomes in women on long-term sick leave.Method: Participants (n = 308), women of working age on long term sick leave due to musculoskeletal pain and/or common mental disorders, were randomized to TEAM (n = 102), ACT (n = 102) or Control (n = 104). Participants in the multidisciplinary assessment treatment program received ACT, but also medical assessment, occupational therapy and social counselling. The second intervention included ACT only. Health outcomes were assessed over 12 months using adjusted linear mixed models. The results showed significant interaction effects for both ACT and TEAM compared with Control in anxiety (ACT [p < 0.05]; TEAM [p < 0.001]), depression (ACT [p < 0.001]; TEAM [p < 0.001]) and general well-being (ACT [p < 0.05]; TEAM [p < 0.001]). For self-rated pain, there was a significant interaction effect in favour of ACT (p < 0.05), and for satisfaction with life in favour of TEAM (p < 0.001).Conclusion: Both ACT alone and multidisciplinary assessment and treatment including ACT were superior to treatment as usual in clinical outcomes.

- Background: The aim was to investigate inferences of statistically significant test results among persons with more or less statistical education and research experience.Methods: A total of 75 doctoral students and 64 statisticians/epidemiologist responded to a web questionnaire about inferences of statistically significant findings. Participants were asked about their education and research experience, and also whether a 'statistically significant' test result (P = 0.024, alpha-level 0.05) could be inferred as proof or probability statements about the truth or falsehood of the null hypothesis (H-0) and the alternative hypothesis (H-1).Results: Almost all participants reported having a university degree, and among statisticians/epidemiologist, most reported having a university degree in statistics and were working professionally with statistics. Overall, 9.4% of statisticians/epidemiologist and 24.0% of doctoral students responded that the statistically significant finding proved that H-0 is not true, and 73.4% of statisticians/epidemiologists and 53.3% of doctoral students responded that the statistically significant finding indicated that H(0 )is improbable. Corresponding numbers about inferences about the alternative hypothesis (H-1) were 12.0% and 6.2% about proving H-1 being true and 62.7 and 62.5% for the conclusion that H-1 is probable. Correct inferences to both questions, which is that a statistically significant finding cannot be inferred as either proof or a measure of a hypothesis' probability, were given by 10.7% of doctoral students and 12.5% of statisticians/epidemiologists.Conclusions: Misinterpretation of P-values and statistically significant test results persists also among persons who have substantial statistical education and who work professionally with statistics.

Tidskriftsartikel (refereegranskat)abstract
- Background: Owing to communication challenges and a lack of knowledge about the health care system, refugees may be at risk of having limited health literacy, meaning that they will have problems in achieving, understanding, appraising and using health information or navigating in the health care system. The aim of this study was to explore experiences and needs concerning health related information for newly arrived refugees in Sweden. Methods: A qualitative design with a focus group methodology was used. The qualitative content analysis was based on seven focus group discussions, including 28 Arabic and Somali speaking refugees. Results: Four categories emerged. ‘Concrete instructions and explanations’ includes appreciation of knowledge about how to act when facing health problems. ‘Contextual knowledge’ comprises experienced needs of information about the health care system, about specific health risks and about rights in health issues. ‘A variation of sources’ describes suggestions as to where and how information should be given. ‘Enabling communication’ includes the wish for more awareness among professionals from a language and cultural point of view. Conclusion: Concrete instructions and explanations are experienced as valuable and applicable. Additional information about health issues and the health care system is needed. Information concerning health should be spread by a variety of sources. Health literate health organizations are needed to meet the health challenges of refugees, including professionals that emphasize health literacy.

- Importance Hypertension is the leading risk factor for premature death worldwide. Multiple blood pressure–lowering therapies are available but the potential for maximizing benefit by personalized targeting of drug classes is unknown.Objective To investigate and quantify the potential for targeting specific drugs to specific individuals to maximize blood pressure effects.Design, Setting, and Participants A randomized, double-blind, repeated crossover trial in men and women with grade 1 hypertension at low risk for cardiovascular events at an outpatient research clinic in Sweden. Mixed-effects models were used to assess the extent to which individuals responded better to one treatment than another and to estimate the additional blood pressure lowering achievable by personalized treatment.Interventions Each participant was scheduled for treatment in random order with 4 different classes of blood pressure–lowering drugs (lisinopril [angiotensin-converting enzyme inhibitor], candesartan [angiotensin-receptor blocker], hydrochlorothiazide [thiazide], and amlodipine [calcium channel blocker]), with repeated treatments for 2 classes.Main Outcomes and Measures Ambulatory daytime systolic blood pressure, measured at the end of each treatment period.Results There were 1468 completed treatment periods (median length, 56 days) recorded in 270 of the 280 randomized participants (54% men; mean age, 64 years). The blood pressure response to different treatments varied considerably between individuals (P < .001), specifically for the choices of lisinopril vs hydrochlorothiazide, lisinopril vs amlodipine, candesartan vs hydrochlorothiazide, and candesartan vs amlodipine. Large differences were excluded for the choices of lisinopril vs candesartan and hydrochlorothiazide vs amlodipine. On average, personalized treatment had the potential to provide an additional 4.4 mm Hg–lower systolic blood pressure.Conclusions and Relevance These data reveal substantial heterogeneity in blood pressure response to drug therapy for hypertension, findings that may have implications for personalized therapy.
