- To investigate the correspondence between diagnoses on sick leave certificates and diagnoses made in structured psychiatric interviews. Secondary aims were to investigate length of sick leave by diagnoses on sick leave certificates, diagnoses made in structured interviews and symptom severity.Observational study consisting of a secondary analysis of data from a randomised controlled trial and an observational study.The regions of Stockholm and Västra Götaland, Sweden.480 people on sick leave for common mental disorders.Participants were examined with structured psychiatric interviews and self-rated symptom severity scales.(1) Sick leave certificate diagnoses, (2) diagnoses from the Mini International Neuropsychiatric Interview and the Self-rated Stress-Induced Exhaustion Disorder (SED) Instrument (s-ED), (3) symptom severity (Montgomery-Asberg Depression Rating Scale-self-rating version and the Karolinska Exhaustion Disorder Scale) and (4) number of sick leave days.There was little correspondence between diagnoses on sick leave certificates and diagnoses made in structured psychiatric interviews. Many participants on sick leave for SED, anxiety disorder or depression fulfilled criteria for other mental disorders. Most on sick leave for SED (76%) and anxiety disorder (67%) had depression (p=0.041). Length of sick leave did not differ by certificate diagnoses. Participants with SED (s-ED) had longer sick leave than participants without SED (144 vs 84 days; 1.72 (1.37-2.16); p<0.001). More severe symptoms were associated with longer sick leave.Diagnoses on sick leave certificates did not reflect the complex and overlapping nature of the diagnoses found in the structured psychiatric interviews. This finding is relevant to the interpretation of information from health data registers, including studies and guidelines based on these data. A result of clinical interest was that more severe symptoms predicted long-term sick leave better than actual diagnoses.

- OBJECTIVE: The aim of this study was to evaluate cost-effectiveness of Acceptance and Commitment Therapy (ACT) and workplace dialogue intervention (WDI), both as stand-alone interventions and in combination, compared with treatment as usual (TAU), for employees on sickness absence with mental disorders.METHODS: Employees (n = 352, 78.4% females) on sickness absence were randomized to one of four groups. Cost-utility analyses were conducted from a health care perspective and a limited societal perspective.RESULTS: All groups reported significant improvements in health-related quality-of-life (HRQoL) and there were no significant differences in HRQoL or costs between groups. The probability of cost-effectiveness for ACT+WDI was 50% compared with ACT, indicating that both treatment alternatives could be considered equally favorable for decision-makers. TAU and WDI were rejected due to less economic efficiency.CONCLUSION: Adding WDI to ACT cannot be recommended on the basis of our study results.

- OBJECTIVE: The objective was to (i) assess the long-term cost-effectiveness of acceptance and commitment therapy (ACT), a workplace dialog intervention (WDI), and ACT+WDI compared to treatment as usual (TAU) for common mental disorders and (ii) investigate any differences in cost-effectiveness between diagnostic groups.METHODS: An economic evaluation from the healthcare and limited welfare perspectives was conducted alongside a randomized clinical trial with a two-year follow-up period. Persons with common mental disorders receiving sickness benefits were invited to the trial. We used registry data for cost analysis alongside participant data collected during the trial and the reduction in sickness absence days as treatment effect. A total of 264 participants with a diagnosis of depression, anxiety, or stress-induced exhaustion disorder participated in a two-year follow-up of a four-arm trial: ACT (N=74), WDI (N=60), ACT+WDI (N=70), and TAU (N=60).RESULTS: For all patients in general, there were no statistically significant differences between interventions in terms of costs or effect. The subgroup analyses suggested that from a healthcare perspective, ACT was a cost-effective option for depression or anxiety disorders and ACT+WDI for stress-induced exhaustion disorder. With a two-year time horizon, the probability of WDI to be cost-saving in terms of sickness benefits costs was 80% compared with TAU.CONCLUSIONS: ACT had a high probability of cost-effectiveness from a healthcare perspective for employees on sick leave due to depression or anxiety disorders. For participants with stress-induced exhaustion disorder, adding WDI to ACT seems to reduce healthcare costs, while WDI as a stand-alone intervention seems to reduce welfare costs.

Forskningsöversikt (refereegranskat)abstract
- Purpose: Common mental disorders (CMDs) and musculoskeletal disorders are highly prevalent in the population and cause significant distress and disability, and high costs to society. The main objective of this systematic review and meta-analysis was to examine the outcome and comparative effectiveness of psychological interventions in reducing sickness absence (SA) due to CMDs or musculoskeletal disorders, compared to a waitlist control group, usual care or another clinical intervention.Methods: We reviewed 3515 abstracts of randomized controlled trials published from 1998 to 2017. Of these, 30 studies were included in the analysis.Results: The psychological interventions were overall more effective than treatment as usual in reducing SA (small effect sizes), but not compared to other clinical interventions. Results were similar for studies on CMDs and musculoskeletal pain. A few significant moderating effects were found for treatment-specific variables. However, these were difficult to interpret as they pointed in different directions.Conclusion: There was a small but significant effect of psychological treatments in reducing SA. We identified areas of improvement such as methodological problems among the included studies and failure to specifically address RTW in the interventions that were evaluated. Clinical implications of the findings, and ways of improving methodological rigour of future studies are discussed.

- Mental disorders contribute to high rates of sickness absence (SA) and impaired work functioning. The aim of the present study was to evaluate the efficacy of 3 interventions targeting SA of workers. Participants (n = 352; 78.4% females) of working age with current employment, and SA due to depression, anxiety disorders, or exhaustion disorder, were recruited to the study and randomized to (a) acceptance and commitment therapy (ACT), (b) a workplace dialogue intervention (WDI), (c) a combination of ACT and WDI, or (d) treatment as usual (TAU). For SA days, there was a significant interaction effect for the follow-up period, in which ACT + WDI generated more SA compared with TAU. When diagnostic group was included as a moderator, participants with exhaustion disorder had less SA days in the WDI group compared with TAU. For symptoms of depression, anxiety, and stress-related ill health, there were significant interaction effects for ACT and ACT + WDI, when compared with TAU, from pre- to postmeasurement (small to moderate between-groups effect sizes). Within-group effect sizes pre- to postmeasurement (Cohen’s d) ranged from .55 to 1.17 (ACT), .40 to .94 (WDI), .26 to 1.13 (ACT + WI), and −.06 to .70 (TAU). There were no differences between groups during follow-up for symptoms.

- OBJECTIVE: Despite access to effective therapies many asthma patients still do not have well-controlled disease. This is possibly related to underuse of inhaled corticosteroids (ICS) and overuse of short-acting β2-agonists (SABA). Our aim was to investigate longitudinal trends and associated factors in asthma treatment.METHODS: Two separate cohorts of adults with physician-diagnosed asthma were randomly selected from 14 hospitals and 56 primary health centers in Sweden in 2005 (n = 1182) and 2015 (n = 1225). Information about symptoms, maintenance treatment, and use of rescue medication was collected by questionnaires. Associations between treatment and sex, age, smoking, education, body mass index (BMI), physical activity, allergic asthma, and symptom control were analyzed using Pearson's chi2-test. Odds ratios (ORs) were calculated using logistic regression.RESULTS: Maintenance treatment with ICS together with long-acting β2-agonists (LABA) and/or montelukast increased from 39.2% to 44.2% (p = 0.012). The use of ICS + LABA as-needed increased (11.1-18.9%, p < 0.001), while SABA use decreased (46.4- 41.8%, p = 0.023). Regular treatment with ICS did not change notably (54.2-57.2%, p = 0.14). Older age, former smoking, and poor symptom control were related to treatment with ICS + LABA/montelukast. In 2015, 22.7% reported daily use of SABA. A higher step of maintenance treatment, older age, obesity, shorter education, current smoking, allergic asthma, low or very high physical activity, and a history of exacerbations were associated with daily SABA use.CONCLUSIONS: The use of ICS + LABA both for maintenance treatment and symptom relief has increased over time. Despite this, the problem of low use of ICS and high use of SABA remains.

Tidskriftsartikel (refereegranskat)abstract
- Spirometry should be used to confirm a diagnosis of chronic obstructive pulmonary disease (COPD). This test is not always performed, leading to possible misdiagnosis. We investigated whether the proportion of patients with diagnostic spirometry has increased over time as well as factors associated with omitted or incorrectly interpreted spirometry. Data from medical reviews and a questionnaire from primary and secondary care patients with a doctors' diagnosis of COPD between 2004 and 2010 were collected. Data were compared with a COPD cohort diagnosed between 2000 and 2003. Among 703 patients with a first diagnosis of COPD between 2004 and 2010, 88% had a diagnostic spirometry, compared with 59% (p < 0.001) in the previous cohort. Factors associated with not having diagnostic spirometry were current smoking (OR 2.21; 95% CI 1.36-3.60), low educational level (OR 1.81; 1.09-3.02) and management in primary care (OR 2.28; 1.02-5.14). The correct interpretation of spirometry results increased (75% vs 82%; p = 0.010). Among patients with a repeated spirometry, 94% had a persistent FEV1/FVC or FEV1/VC ratio <0.70.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Asthma severity can be estimated as the level of medication needed to achieve asthma control or by the patient's subjective assessment. Factors associated with self-assessed asthma severity are still incompletely explored.AIM: The aim was to study factors associated with self-assessed moderate or severe asthma.METHOD: In total, 1828 randomly selected asthma patients from primary (69%) and secondary (31%) care, completed a questionnaire including items about patient characteristics, comorbidity, the Asthma Control Test (ACT), emergency care visits and a scale for self-assessed asthma severity. Logistic regression was used to analyze associations with the dependent variable, self-assessed moderate or severe asthma in the entire study population and stratified by sex.RESULTS: Of the patients, 883 (45%) reported having moderate or severe asthma. Factors independently associated with self-assessed moderate or severe asthma were age >60 years (OR [95% CI] 1.98 [1.37-2.85]), allergic rhino-conjunctivitis (1.43 [1.05-1.95]), sinusitis (1.45 [1.09-1.93]), poor asthma control as measured by ACT <20 (5.64 [4.45-7.16]) and emergency care visits the previous year (2.52 [1.90-3.34]). Lower level of education was associated with self-assessed moderate/severe asthma in women (1.16 [1.05-2.43]) but not in men (0.90 [0.65-1.25]), p for interaction = .012.CONCLUSION: Poor asthma control, allergic rhino-conjunctivitis, recent sinusitis and older age were independently associated with self-assessed moderate or severe asthma. Important implications are that comorbid conditions of the upper airways should always be considered as part of asthma management, and that elderly patients may need extra attention.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) and no exacerbations may need less maintenance treatment and follow-up. The aim was to identify factors associated with a non-exacerbator COPD phenotype.METHODS: Cross-sectional analysis of 1354 patients from primary and secondary care, with a doctor's diagnosis of COPD. In 2014, data on demographics, exacerbation frequency and symptoms using COPD Assessment Test (CAT) were collected using questionnaires and on spirometry and comorbid conditions by record review. The non-exacerbator phenotype was defined as having reported no exacerbations the previous six months. Multivariable logistic regression with the non-exacerbator phenotype as dependent variable was performed, including stratification and interaction analyses by sex.RESULTS: The non-exacerbator phenotype was found in 891 (66%) patients and was independently associated with COPD stage 1 (OR [95% CI] 5.72 [3.30-9.92]), stage 2 (3.42 [2.13-5.51]) and stage 3 (2.38 [1.46-3.88]) compared with stage 4, and with CAT score <10 (3.35 [2.34-4.80]). Chronic bronchitis and underweight were inversely associated with the non-exacerbator phenotype (0.47 [0.28-0.79]) and (0.68 [0.48-0.97]), respectively. The proportion of non-exacerbators was higher among patients with no maintenance treatment or a single bronchodilator. The association of COPD stage 1 compared with stage 4 with the non-exacerbator phenotype was stronger in men (p for interaction 0.048). In women, underweight and obesity were both inversely associated with the non-exacerbator phenotype (p for interaction 0.033 and 0.046 respectively), and in men heart failure was inversely associated with the non-exacerbator phenotype (p for interaction 0.030).CONCLUSION: The non-exacerbator phenotype is common, especially in patients with no maintenance treatment or a single bronchodilator, and is characterized by preserved lung function, low symptom burden, and by absence of chronic bronchitis, underweight and obesity and heart failure. We suggest these patients may need less treatment and follow-up, but that management of comorbid conditions is important to avoid exacerbations.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To study risk factors for uncontrolled asthma and insufficient quality of life (QoL) in patients with mild asthma, ie those without preventer treatment.Patients and Methods: Patients aged 18-75 years with a doctor's diagnosis of asthma randomly selected from primary and secondary care in Sweden. Mild asthma was defined as self-reported current asthma and no preventer treatment. Data were collected from self-completed questionnaires in 2012 and 2015. Well-controlled asthma was defined as Asthma Control Test (ACT) >20 points and no exacerbation and uncontrolled asthma as ACT<20 points and/or at least one exacerbation in the previous six months. QoL was measured by the Mini Asthma Quality of Life Questionnaire (Mini-AQLQ), where a total mean score of > 6 indicated sufficient and < 6 insufficient QoL. Multivariate logistic regression analyses were performed using asthma control and Mini-AQLQ as dependent variables. Asthma control was dichotomized as controlled and uncontrolled asthma and the Mini-AQLQ as sufficient QoL (mean score >6) and insufficient QoL (mean score <6).Results: Among 298 patients, 26% had uncontrolled asthma, 40% insufficient QoL and 20% both uncontrolled asthma and insufficient QoL. Age >60 years, obesity, daily smoking, rhinitis and inadequate knowledge of asthma self-management were independently associated with poor asthma control. Factors independently associated with insufficient QoL were age >60 years, overweight, obesity, rhinitis, sinusitis and inadequate knowledge of asthma self-management. Age >60 years, obesity, rhinitis and inadequate knowledge of asthma self-management were independently associated with both uncontrolled asthma and insufficient QoL.Conclusion: Among asthma patients without preventer medication, 26% had uncontrolled asthma and 40% had insufficient asthmarelated QoL. Older age, obesity, and rhinitis were risk factors for both poor asthma control and a reduced QoL, but having good knowledge of asthma self-management reduced this risk. Our findings suggest that this group of patients requires further attention and follow-up.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: The aim of this study was to examine the association of comorbid heart disease, defined as chronic heart failure or ischemic heart disease, on all-cause and cause-specific hospitalization and mortality in patients with COPD over a period of nearly 15 years.MATERIALS AND METHODS: The cohort study included patients with COPD from primary and secondary care in 2005 with data from questionnaires and medical record reviews. The Swedish Board of Health and Welfare provided hospitalization and mortality data from 2005 through 2019. Cox regression analyses, adjusted for sex, age, educational level, smoking status, BMI, exacerbations, dyspnea score and comorbid diabetes or hypertension, assessed the association of comorbid heart disease with all-cause and cause-specific time to first hospitalization and death. Linear regression analyses, adjusted for the same variables, assessed this association with hospitalization days per year for those patients that had been hospitalized.RESULTS: Of the 1071 patients, 262 (25%) had heart disease at baseline. Cox regression analysis showed a higher risk of hospitalization for patients with heart disease for all-cause (HR (95% CI) 1.55; 1.32-1.82), cardiovascular (2.14; 1.70-2.70) and other causes (1.27; 1.06-1.52). Patients with heart disease also had an increased risk of all-cause (1.77; 1.48-2.12), cardiovascular (3.40; 2.41-4.78) and other (1.50; 1.09-2.06) mortality. Heart disease was significantly associated with more hospitalization days per year of all-cause (regression coefficient 0.37; 95% CI 0.15-0.59), cardiovascular (0.57; 0.27-0.86) and other (0.37; 0.12-0.62) causes. No significant associations were found between heart disease and respiratory causes of hospitalization and death.CONCLUSION: Comorbid heart disease in patients with COPD is associated with an increased risk for all-cause hospitalization and mortality, mainly due to an increase of hospitalization and death of cardiovascular and other causes, but not because of respiratory disease. This finding advocates the need of a strong clinical focus on primary and secondary prevention of cardiovascular disease in patients with COPD.

- Objectives: The aim was to investigate if menstruation and use of exogenous sex hormones influence self-reported asthma related quality of life (QoL) and asthma control.Methods: The study is based on two asthma cohorts randomly selected in primary and secondary care. A total of 622 female patients 18-65 years were included and classified as premenopausal ≤46 years (n = 338) and peri/postmenopausal 47-65 years (n = 284). Questionnaire data from 2012 and 2014 with demographics, asthma related issues and sex hormone status. Outcome measures were Mini Asthma Quality of Life Questionnaire (Mini-AQLQ) and asthma control including Asthma Control Test (ACT) and exacerbations last six months.Results: Premenopausal women with menstruation related asthma worsening, perimenstrual asthma (PMA) (9%), had a clinically relevant lower Mini-AQLQ mean score 4.9 vs. 5.8 (p < 0.001), lower asthma control with ACT score <20, 72% vs. 28% (p < 0.001) and higher exacerbation frequency 44% vs. 20% (p = 0.004) compared with women without PMA. Women with irregular menstruation had higher exacerbation frequency than women with regular menstruation (p = 0.023). Hormonal contraceptives had no impact on QoL and asthma control. Peri/postmenopausal women with menopausal hormone therapy (MHT) had a clinically relevant lower Mini-AQLQ mean score compared to those without MHT, 4.9 vs 5.4 (p < 0.001), but no differences in asthma control.Conclusion: Women with PMA had lower QoL and more uncontrolled asthma than women without PMA. Peri/postmenopausal women with MHT had lower QoL than women without MHT. Individual clinical management of women with asthma may benefit from information about their sex hormone status.

Data-driven questionnaire-based cluster analysis of asthma in Swedish adults
- 2020
-
Ingår i: npj Primary Care Respiratory Medicine. - : Nature Research. - 2055-1010. ; 30:1
-
Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to identify asthma phenotypes through cluster analysis. Cluster analysis was performed using self-reported characteristics from a cohort of 1291 Swedish asthma patients. Disease burden was measured using the Asthma Control Test (ACT), the mini Asthma Quality of Life Questionnaire (mini-AQLQ), exacerbation frequency and asthma severity. Validation was performed in 748 individuals from the same geographical region. Three clusters; early onset predominantly female, adult onset predominantly female and adult onset predominantly male, were identified. Early onset predominantly female asthma had a higher burden of disease, the highest exacerbation frequency and use of inhaled corticosteroids. Adult onset predominantly male asthma had the highest mean score of ACT and mini-AQLQ, the lowest exacerbation frequency and higher proportion of subjects with mild asthma. These clusters, based on information from clinical questionnaire data, might be useful in primary care settings where the access to spirometry and biomarkers is limited.

Clutch-size variation in Western Palaearctic secondary hole-nesting passerine birds in relation to nest box design
- 2014

Ingår i: Methods in Ecology and Evolution. - 2041-210X. ; 5:4, s. 353-362

Tidskriftsartikel (refereegranskat)abstract
- Secondary hole-nesting birds that do not construct nest holes themselves and hence regularly breed in nest boxes constitute important model systems for field studies in many biological disciplines with hundreds of scientists and amateurs involved. Those research groups are spread over wide geographic areas that experience considerable variation in environmental conditions, and researchers provide nest boxes of varying designs that may inadvertently introduce spatial and temporal variation in reproductive parameters. We quantified the relationship between mean clutch size and nest box size and material after controlling for a range of environmental variables in four of the most widely used model species in the Western Palaearctic: great tit Parus major, blue tit Cyanistes caeruleus, pied flycatcher Ficedula hypoleuca and collared flycatcher F.albicollis from 365 populations and 79610 clutches. Nest floor area and nest box material varied non-randomly across latitudes and longitudes, showing that scientists did not adopt a random box design. Clutch size increased with nest floor area in great tits, but not in blue tits and flycatchers. Clutch size of blue tits was larger in wooden than in concrete nest boxes. These findings demonstrate that the size of nest boxes and material used to construct nest boxes can differentially affect clutch size in different species. The findings also suggest that the nest box design may affect not only focal species, but also indirectly other species through the effects of nest box design on productivity and therefore potentially population density and hence interspecific competition.

Effects of interspecific coexistence on laying date and clutch size in two closely related species of hole-nesting birds

Tidskriftsartikel (refereegranskat)abstract
- Coexistence between great tits Parus major and blue tits Cyanistes caeruleus, but also other hole-nesting taxa, constitutes a classic example of species co-occurrence resulting in potential interference and exploitation competition for food and for breeding and roosting sites. However, the spatial and temporal variations in coexistence and its consequences for competition remain poorly understood. We used an extensive database on reproduction in nest boxes by great and blue tits based on 87 study plots across Europe and Northern Africa during 1957-2012 for a total of 19,075 great tit and 16,729 blue tit clutches to assess correlative evidence for a relationship between laying date and clutch size, respectively, and density consistent with effects of intraspecific and interspecific competition. In an initial set of analyses, we statistically controlled for a suite of site-specific variables. We found evidence for an effect of intraspecific competition on blue tit laying date (later laying at higher density) and clutch size (smaller clutch size at higher density), but no evidence of significant effects of intraspecific competition in great tits, nor effects of interspecific competition for either species. To further control for site-specific variation caused by a range of potentially confounding variables, we compared means and variances in laying date and clutch size of great and blue tits among three categories of difference in density between the two species. We exploited the fact that means and variances are generally positively correlated. If interspecific competition occurs, we predicted a reduction in mean and an increase in variance in clutch size in great tit and blue tit when density of heterospecifics is higher than the density of conspecifics, and for intraspecific competition, this reduction would occur when density of conspecifics is higher than the density of heterospecifics. Such comparisons of temporal patterns of means and variances revealed evidence, for both species, consistent with intraspecific competition and to a smaller extent with interspecific competition. These findings suggest that competition associated with reproductive behaviour between blue and great tits is widespread, but also varies across large spatial and temporal scales.

- Nests are structures built to support and protect eggs and/or offspring from predators, parasites, and adverse weather conditions. Nests are mainly constructed prior to egg laying, meaning that parent birds must make decisions about nest site choice and nest building behavior before the start of egg-laying. Parent birds should be selected to choose nest sites and to build optimally sized nests, yet our current understanding of clutch size-nest size relationships is limited to small-scale studies performed over short time periods. Here, we quantified the relationship between clutch size and nest size, using an exhaustive database of 116 slope estimates based on 17,472 nests of 21 species of hole and non-hole-nesting birds. There was a significant, positive relationship between clutch size and the base area of the nest box or the nest, and this relationship did not differ significantly between open nesting and hole-nesting species. The slope of the relationship showed significant intraspecific and interspecific heterogeneity among four species of secondary hole-nesting species, but also among all 116 slope estimates. The estimated relationship between clutch size and nest box base area in study sites with more than a single size of nest box was not significantly different from the relationship using studies with only a single size of nest box. The slope of the relationship between clutch size and nest base area in different species of birds was significantly negatively related to minimum base area, and less so to maximum base area in a given study. These findings are consistent with the hypothesis that bird species have a general reaction norm reflecting the relationship between nest size and clutch size. Further, they suggest that scientists may influence the clutch size decisions of hole-nesting birds through the provisioning of nest boxes of varying sizes.

- Nager A, Szulkin R, Johansson S-E, Johansson L-M, Sundquist K. High lifelong relapse rate of psychiatric disorders among women with postpartum psychosis. Nord J Psychiatry 2013;67:53-58. Background: The relapse rate for psychiatric disorders after postpartum psychosis is high. Apart from subsequent puerperal periods, previous studies have not examined when relapses in psychiatric disorders occur. In addition, little is known about the impact of certain individual factors on the risk of non-puerperal readmission among women with previous postpartum psychosis. Aims: The first aim was to examine the association between non-puerperal readmission due to psychiatric disorders and years of follow-up (in total, 30 years) in women with postpartum psychosis. The second aim was to examine the impact of age, type of psychosis, previous hospitalization for psychiatric disorders and level of education on the risk of non-puerperal readmission due to psychiatric disorders. Methods: All Swedish women aged 20-44 with postpartum psychosis (n = 3140) were followed between 1975 and 2004 for non-puerperal readmission due to psychiatric disorders. A Cox frailty regression model was used to estimate hazard ratios for non-puerperal readmission. Results: The risk of non-puerperal readmission, although gradually decreasing with time, remained high many years after the postpartum psychosis. The risk of non-puerperal readmission was significantly higher among women with schizophrenia, lower levels of education and previous psychiatric hospitalization. Conclusions: Postpartum psychosis is often part of a lifelong recurrent psychiatric disorder. Women with schizophrenia, lower levels of education and hospitalization due to a psychiatric disorder prior to postpartum psychosis have a higher risk of non-puerperal readmission. Clinical implications: The findings constitute important knowledge for all healthcare workers encountering women with a previous postpartum psychosis.

Postpartum psychosis and the association with sociodemographic and obstetric factors
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Objective: To examine the association between postpartum psychosis and the sociodemographic factors age, education, marital status and year of delivery (study 1). To examine the association between neighbourhood socioeconomic characteristics and postpartum psychosis (study 2). To examine the association between postpartum psychosis and obstetric factors (study 3). To examine the association between non-puerperal readmission and years of follow-up among women with postpartum psychosis and to examine the impact of age, type of psychosis, previous psychiatric hospitalisation and education on the risk of non-puerperal readmission (study 4) among these women. Methods: Data sources were the Swedish population registers and medical registers. Postpartum psychosis was defined as hospital admission due to psychotic disorder within three months after delivery, which was the outcome variable in studies 1 3. Study 1 followed 502,767 first-time mothers between Jan. 1, 1986, and Dec. 31, 1997, for postpartum psychosis. Study 2 followed 485,199 first-time mothers between Jan. 1, 1986, and Sept. 30, 1998, for postpartum psychosis. Study 3 followed 1,133,368 first-time mothers between Jan. 1, 1975, and Dec. 31, 2003, for postpartum psychosis. Study 4 followed 1,340 women with postpartum psychosis between Jan. 1, 1975, and Dec. 31, 2004, for non-puerperal readmission due to psychiatric disorder. The explanatory variables included age (studies 1 4), education (studies 1, 2, 4) marital status (studies 1, 2), year of delivery (studies 1 3), neighbourhood income (study 2), previous psychiatric hospitalisation (studies 3, 4), years of follow-up (study 4), type of psychosis (study 4), calendar year (study 4), and 19 different obstetric factors (study 3). Cox regression models (studies 1 3) and Cox frailty regression models (study 4) were used in the statistical analysis. Results: Old age in the mother, not living with the father of the child, living in a socioeconomically deprived neighbourhood, preterm birth and acute caesarean section were associated with increased risk of postpartum psychosis among first-time mothers after adjustment for possible confounders. However, the HRs for these factors were only moderately increased, which implies that the absolute increase in risk is small. In contrast, previous hospitalisation for psychiatric disorders was associated with a more than 100-fold increased risk of postpartum psychosis. The risk of non-puerperal readmission due to a psychiatric disorder remained high for many years after the postpartum psychosis, for all women in the study group. In addition, the risk of non-puerperal readmission due to a psychiatric disorder was higher among women with low educational level, previous psychiatric hospitalisation and schizophrenia. Conclusion: Stress from adverse sociodemographic and obstetric conditions can possibly play a role in the development of postpartum psychosis, although these associations might be confounded by unknown previous psychiatric illness. Postpartum psychosis is often part of a severe and chronic psychiatric illness, with high non-puerperal readmission rates for many years after the postpartum psychosis. Finally, previous psychiatric disorder is a strong risk factor for postpartum psychosis. Therefore, it is very important to consider previous psychiatric disorder in antenatal and postnatal care.

- We studied the relationship between temperature and the coexistence of great tit Parus major and blue tit Cyanistes caeruleus, breeding in 75 study plots across Europe and North Africa. We expected an advance in laying date and a reduction in clutch size during warmer springs as a general response to climate warming and a delay in laying date and a reduction in clutch size during warmer winters due to density‐dependent effects. As expected, as spring temperature increases laying date advances and as winter temperature increases clutch size is reduced in both species. Density of great tit affected the relationship between winter temperature and laying date in great and blue tit. Specifically, as density of great tit increased and temperature in winter increased both species started to reproduce later. Density of blue tit affected the relationship between spring temperature and blue and great tit laying date. Thus, both species start to reproduce earlier with increasing spring temperature as density of blue tit increases, which was not an expected outcome, since we expected that increasing spring temperature should advance laying date, while increasing density should delay it cancelling each other out. Climate warming and its interaction with density affects clutch size of great tits but not of blue tits. As predicted, great tit clutch size is reduced more with density of blue tits as temperature in winter increases. The relationship between spring temperature and density on clutch size of great tits depends on whether the increase is in density of great tit or blue tit. Therefore, an increase in temperature negatively affected the coexistence of blue and great tits differently in both species. Thus, blue tit clutch size was unaffected by the interaction effect of density with temperature, while great tit clutch size was affected in multiple ways by these interactions terms.

Tidskriftsartikel (refereegranskat)abstract
- Background: Chronic obstructive pulmonary disease (COPD) is a common cause of morbidity and mortality worldwide. It is often undiagnosed and insufficiently managed. Effective forms of continuing medical education (CME) for primary care physicians (PCPs) are necessary to ensure the implementation of guidelines in clinical practice and, thus, improve patients' health.Methods: In this study, we will measure the effects of CME by Case Method and compare them against those of traditional lectures and no CME at all through an unblinded, cluster randomised controlled trial (CRCT). Thirty-three primary health care centres (PHCCs) in Stockholm, Sweden, with a total of 180 PCPs will be involved. Twenty-two primary PHCCs, will be cluster-randomised into: an intervention group who will receive CME by Case Method (n = 11) and a control group who will receive traditional lectures (n = 11). The remaining PHCCs (n = 11) will be a reference group and will receive no CME. From the intervention and control groups, 460 randomly selected patients with COPD in GOLD stages 2 and 3 will participate, while no patients will be recruited from the reference group.For the patients, smoking status, actual treatment and urgent visits to a health provider due to airway problems will be registered. For the PCPs, professional competence (i.e. knowledge and management skills) in COPD, will be measured using a questionnaire based on current guidelines and guideline implementation problems in clinical practice which has previously been described by the authors. Data will be collected at baseline and at follow-up, which will be after 1.5 years for the patients, and 1 year for the PCPs. Statistical methods for individual-level and cluster-level analyses will be used.Discussion: COPD is considered a particularly complex clinical challenge involving managing multimorbidity, symptom adaptation, and lifestyle problematisation. Case Method in CME for PCPs may contribute to a better understanding of the impact of COPD on patients' lives and, thus, improve their management of it. The present study is expected to contribute scientific knowledge about indicators for an effective CME in COPD that is tailor-made to primary care physicians.

Tidskriftsartikel (refereegranskat)abstract
- Background: Chronic obstructive pulmonary disease (COPD) is a common cause of suffering and death. Evidence-based management of COPD by general practitioners (GPs) is crucial for decreasing the impact of the disease. Efficient strategies include early diagnosis, smoking cessation and multimodal treatment.Aim: To describe knowledge about and skills for managing COPD in GPs in Sweden.Methods: Prior to COPD education (the PRIMAIR Study), GPs at primary health care centers (PHCCs) in Stockholm replied to 13 written, patient-case based, multiple choice and free-text questions about COPD. Their knowledge and practical management skills were assessed by assigned points that were analyzed with non-parametric tests.Results: Overall, 250 GPs at 34 PHCCs replied (89% response rate). Total mean score was 9.9 (maximum 26). Scores were highest on ‘management of smoking cessation’, ‘follow-up after exacerbation’ and ‘diagnostic procedures’. Spirometry was used frequently, although interpretation skills were suboptimal. ‘Management of maintenance therapy’, ‘management of multimorbidity’ and ‘interprofessional cooperation’ had mediocre scores. Scores were unrelated to whether there was a nurse-led asthma/COPD clinic at the PHCC.Conclusions: Swedish GPs’ knowledge of COPD and adherence to current guidelines seem insufficient. A nurse-led asthma/COPD clinic at the PHCC does not correlate with sufficient COPD skills in the GPs. The relevance of this study to participants’ actual clinical practice and usefulness of easy-to-access clinical guides are interesting topics for future investigation. To identify problem areas, we suggest using questionnaires prior to educational interventions.
