Aims Heart failure (HF) is a leading cause of hospitalization and is associated with high morbidity and mortality. We examined the impact of recurrent HF hospitalizations (HFHs) on cardiovascular (CV) mortality among patients with HF in Sweden. Methods and results Adults with incident HF were identified from linked national health registers and electronic medical records from 01 January 2005 to 31 December 2013 for Uppsala and until 31 December 2014 for Västerbotten. CV mortality and all‐cause mortality were evaluated. A time‐dependent Cox regression model was used to estimate relative CV mortality rates for recurrent HFHs. Assessment was also done for ejection fraction‐based HF phenotypes and for comorbid atrial fibrillation, diabetes, or chronic renal impairment. Overall, 3878 patients with HF having an index hospitalization were included, providing 9691.9 patient‐years of follow‐up. Patients were relatively old (median age: 80 years) and were more frequently male (55.5%). Compared with patients without recurrent HFHs, the adjusted hazard ratio (HR [95% confidence interval; CI]) for CV mortality and all‐cause mortality were statistically significant for patients with one, two, three, and four or more recurrent HFHs. The risk of CV mortality and all‐cause mortality increased approximately six‐fold in patients with four or more recurrent HFHs vs. those without any HFHs (HR [95% CI]: 6.26 [5.24–7.48] and 5.59 [4.70–6.64], respectively). Similar patterns were observed across the HF phenotypes and patients with comorbidities. Conclusions There is a strong association between recurrent HFHs and CV and all‐cause mortality, with the risk increasing progressively with each recurrent HFH.

Background Comorbidity is of significant concern in multiple sclerosis (MS). Few population-based studies have reported conditions occurring in MS after diagnosis, especially in contemporary cohorts. Objective To explore incident comorbidity, mortality and hospitalizations in MS, stratified by age and sex. Methods In a Swedish population-based cohort study 6602 incident MS patients (aged ≥18 years) and 61,828 matched MS-free individuals were identified between 1 January 2008 and 31 December 2016, using national registers. Incidence rates (IRs) and incidence rate ratios (IRRs) with 95% CI were calculated for each outcome. Results IRs of cardiovascular disease (CVD) were higher among MS patients than MS-free individuals, (major adverse CVD: IRR 1.42; 95% CI 1.12–1.82; hemorrhagic/ischemic stroke: 1.46; 1.05–2.02; transient ischemic attack: 1.65; 1.09–2.50; heart failure: 1.55; 1.15–2.10); venous thromboembolism: 1.42; 1.14–1.77). MS patients also had higher risks of several non-CVDs such as autoimmune conditions (IRR 3.83; 3.01–4.87), bowel dysfunction (2.16; 1.86–2.50), depression (2.38; 2.11–2.68), and fractures (1.32; 1.19–1.47), as well as being hospitalized and to suffer from CVD-related deaths ((1.91; 1.00–3.65), particularly in females (3.57; 1.58–8.06)). Conclusion MS-patients experience a notable comorbidity burden which emphasizes the need for integrated disease management in order to improve patient care and long-term outcomes of MS.

Background Multiple sclerosis (MS) is associated with serious morbidity and labor force absenteeism, but little is known of the long-term impact of the disease on personal income. Objectives To assess long-term consequences of MS on personal salary and disposable income. Methods Patients with MS in Sweden were identified in a nationwide, disease-specific register and matched with general population controls. We assessed mean annual personal gross salary and disposable income each year before and after index (i.e., the MS diagnosis date) using data from national registers. Results The final sample consisted of 5,472 patients and 54,195 controls (mean age 39 years; 70% females). There was no significant difference in gross salary between patients and controls in any year within the pre-index period. In contrast, on average during follow-up post diagnosis, patients with MS had €5,130 less gross salary per year compared with controls, ranging from a loss of €2,430 the first year to €9,010 after 11 years. Within 10 years after index, 45% of patients had at least one record of zero gross salary, compared with 32% for controls. Mean annual disposable income was comparable between patients and controls across follow-up, with significant differences only at years 9 and 10 post-index. Conclusions We show that many patients with MS in Sweden lose their ability to support for themselves financially but still have a relatively high disposable income because of social transfers. Our findings underscore the detrimental impact of MS on affected patients and the considerable economic burden of disease to society.

Objective The objective of this retrospective, observational study was to estimate the long-term impact of early treatment of multiple sclerosis (MS) on the risk of disability pension. Methods Our cohort comprised patients with MS in Sweden, identified in a nationwide disease-specific register (the Swedish Multiple Sclerosis Registry), who started treatment with a disease-modifying drug (DMD) between January 1, 2002, and December 31, 2012. We analyzed the association between time from onset of MS to treatment initiation and full-time disability pension using survival analysis. Results Our sample comprised 2477 patients. Unadjusted Kaplan–Meier failure functions showed that patients who started treatment within six months after onset had a lower risk of disability pension across follow-up compared with patients initiating therapy after 12 months. Outcomes from the univariate Cox proportional hazards model showed that time from onset to treatment initiation (in years) was significantly associated with disability pension (HR 1.03, p

Purpose The purpose of this study was to examine the trends in heart failure (HF) epidemiology and diagnostic work-up in Sweden. Methods Adults with incident HF (≥2 ICD-10 diagnostic codes) were identified from linked national health registers (cohort 1, 2005–2013) and electronic medical records (cohort 2, 2010–2015; primary/secondary care patients from Uppsala and Västerbotten). Trends in annual HF incidence rate and prevalence, risk of all-cause and cardiovascular disease (CVD)-related 1-year mortality and use of diagnostic tests 6 months before and after first HF diagnosis (cohort 2) were assessed. Results Baseline demographic and clinical characteristics were similar for cohort 1 (N=174,537) and 2 (N=8,702), with mean ages of 77.4 and 76.6 years, respectively; almost 30% of patients were aged ≥85 years. From 2010 to 2014, age-adjusted annual incidence rate of HF/1,000 inhabitants decreased (from 3.20 to 2.91, cohort 1; from 4.34 to 3.33, cohort 2), while age-adjusted prevalence increased (from 1.61% to 1.72% and from 2.15% to 2.18%, respectively). Age-adjusted 1-year all-cause and CVD-related mortality was higher in men than in women among patients in cohort 1 (all-cause mortality hazard ratio [HR] men vs women 1.07 [95% CI 1.06–1.09] and CVD-related mortality subdistribution HR for men vs women 1.04 [95% CI 1.02–1.07], respectively). While 83.5% of patients underwent N-terminal pro-B-type natriuretic peptide testing, only 36.4% of patients had an echocardiogram at the time of diagnosis, although this increased overtime. In the national prevalent HF population (patients with a diagnosis in 1997–2004 who survived into the analysis period; N=273,999), death from ischemic heart disease and myocardial infarction declined between 2005 and 2013, while death from HF and atrial fibrillation/flutter increased (P

Background Multiple sclerosis (MS) patients have an increased risk of infections, but few population-based studies have reported infections occurring in MS in the years immediately after diagnosis. Objective To explore incident infections in MS, stratified by age and sex. Methods In a Swedish population-based cohort study 6602 incident MS patients (aged ≥18 years), matched at diagnosis with 61,828 matched MS-free individuals were identified between 1st January 2008 and 31st December 2016, using national registers. Incidence rates (IR) and incidence rate ratios (IRR) with 95% CI were calculated for each outcome. Results The IRRs were 2.54 (95% CI 2.28–2.83) for first serious infection and 1.61 (1.52–1.71) for first non-serious infection. Compared with MS-free individuals, MS patients had higher IRs for skin, respiratory/throat infections, pneumonia/influenza, bacterial, viral, and fungal infections, with the highest IRR observed for urinary tract/kidney infections (2.44; 2.24–2.66). The cumulative incidence for most of these infections was higher among MS patients than MS-free individuals, both 0 to Conclusion The burden of infections around the time of MS diagnosis and subsequent infection risk, underscore the need for careful considerations regarding the risk-benefit across different disease-modifying therapies.

BACKGROUND AND PURPOSE Multiple sclerosis (MS) is a chronic neurological disease associated with substantial disability and morbidity. The objective of our study was to assess the long-term consequences of MS clinical course on sick leave and disability pension. METHODS Patients with relapsing-remitting MS (RRMS), secondary progressive MS (SPMS) and primary progressive MS (PPMS) were identified through the Swedish Multiple Sclerosis Registry. We calculated the mean annual prevalence and number of sick leave and disability pension days by clinical course, age and year pre- and post-diagnosis, and compared outcomes using Welch's t-tests and ANOVA models, mixed-effects regression and survival analysis. RESULTS The sample included 5371 patients (4568 with RRMS, 390 with SPMS and 413 with PPMS). The mean annual number of days with sick leave and disability pension ranged from 101 at 1 year after diagnosis to 164 after 11 years for patients with RRMS. Corresponding estimates for PPMS were 188 and 311 days. Higher levels of absenteeism were observed in patients with PPMS versus RRMS 7 years before diagnosis for sick leave (P

Background Several studies have investigated the impact of multiple sclerosis (MS) on the risk of divorce. However, current evidence is inconclusive and limited by e.g. small sample populations, short follow-up, and/or lack of a control group. The objective of this retrospective, observational study was to estimate the long-term impact of MS on the risk of divorce. Methods Swedish patients diagnosed with MS between 1975 and 2012 were identified in a nationwide disease-specific register (the Swedish Multiple Sclerosis Registry) and matched with general population controls based on age, sex, region of residency, and marital status. We used survival analysis to estimate the cumulative incidence proportion of divorce after index (i.e. the MS diagnosis date). Results Our final sample comprised 3998 patients and 15,992 general population controls (mean age 44 years; 73% female). Mean follow-up was 10 years (range: 1–37 years). Unadjusted Kaplan-Meier failure functions revealed no significant differences in the cumulative incidence proportion of divorce between patients and controls (log-rank test, p = 0.902), or women with MS and female controls (p = 0.157). In contrast, men with MS were estimated to have a notably higher incidence of divorce compared with male controls (p = 0.040). Cox proportional-hazards model outcomes showed that men with MS had a 21% higher risk (HR: 1.21, p = 0.032) of divorce across follow-up compared with male controls when controlling for age, region of residency, and year of diagnosis. No significant adjusted risk increase was found for women with MS. Conclusions We show that MS is associated with an increased risk of divorce among men, but not women. Our result should be helpful to inform health policy and clinical interventions, such as relationship counselling programs, and highlight the socio-economic burden of the disease.

Background: Multiple sclerosis (MS) is associated with considerable morbidity and serious disability, but little is known of the long-term impact of the disease on work ability. Objectives: To assess sick leave (short-term absence) and disability pension (long-term absence) before and after diagnosis of MS. Methods: Patients with MS in Sweden were identified in a nationwide disease-specific register and matched with general population controls. Sick leave and disability pension were measured before and after index (i.e. the MS diagnosis date). Results: The final sample comprised 6092 patients and 60,345 controls (mean age 39 years; 70% female). The mean annual prevalence of sick leave ranged from 12% the first year after index to 23% after 11 years among patients and from 13% to 13% among controls. Corresponding estimates for disability pension were 12% and 55% for patients and 7% and 9% for controls. Significant differences in sick leave were observed up to 15 years before index and 3 years for disability pension. Conclusion: Patients with MS in Sweden have elevated levels of sick leave and disability pension up to 15 years before disease diagnosis. Our results highlight the burden of disease on affected patients and society and underscore the substantial unmet medical need.
