- Purpose: To identify overuse of methylphenidate and to investigate patterns of overuse in relation to sociodemographic and clinical characteristics. Patients and methods: Swedish national, pharmacy dispensing data were analyzed for all 56,922 individuals aged 6-79 years, who filled a methylphenidate prescription between 2010 and 2011. Overuse was defined as having above 150% days covered by the dispensed amount during 365 days from the first prescription fill, assuming use at the maximum recommended daily dose. Results: In total, 4,304 individuals (7.6% of the methylphenidate users) were categorized as overusers. The risk of overuse increased with age (OR for 46-65 years vs 6-12 years 17.5, 95% CI 14.3-21.3), and was higher in men (OR 1.4, 95% CI 1.3-1.5) and individuals with low income (OR 1.1, 95% CI 1.0-1.2), as well as in individuals with an attention deficit hyperactivity disorder (ADHD) diagnosis (OR 1.4, 95% CI 1.3-1.6), health care visits (OR 1.3, 95% CI 1.2-1.4), previous ADHD medication use (OR 2.6, 95% CI 2.4-2.8), and previous diagnosis of mental and behavioral disorders due to psychoactive substance use (OR 2.1 95% CI 2.0-2.3). Conclusion: Among individuals using methylphenidate in Sweden, 7.6% receive amounts that are larger than what they should have a medical need for, assuming that they were using the maximum recommended daily dose 365 days per year. Notably, the prevalence of overuse was associated with previous diagnosis of alcohol and drug misuse. The prevalence was also positively associated with higher age and previous use of ADHD medication. These findings may point toward a link between exposure time and overuse. However, future studies with long-term data are needed to investigate this.

- Background: Cardiovascular diseases are leading causes of death and patients with dementia are often affected by them. Objective: Investigate associations of cardiovascular diseases with different dementia disorders and determine their impact on mortality. Methods: This study included 29,630 patients from the Swedish Dementia Registry (mean age 79 years, 59% women) diagnosed with Alzheimer's disease (AD), mixed dementia, vascular dementia, dementia with Lewy bodies (DLB), Parkinson's disease dementia (PDD), frontotemporal dementia (FTD), or unspecified dementia. Records of cardiovascular diseases come from the Swedish National Patient Register. Multinomial logistic regression and cox proportional hazard models were applied. Results: Compared to AD, we found a higher burden of all cardiovascular diseases in mixed and vascular dementia. Cerebrovascular diseases were more associated with DLB than with AD. Diabetes mellitus was less associated with PDD and DLB than with AD. Ischemic heart disease was less associated with PDD and FTD than AD. All cardiovascular diseases predicted death in patients with AD, mixed, and vascular dementia. Only ischemic heart disease significantly predicted death in DLB patients (HR = 1.72; 95% CI = 1.16-2.55). In PDD patients, heart failure and diabetes mellitus were associated with a higher risk of death (HR = 3.06; 95% CI = 1.74-5.41 and HR = 3.44; 95% CI = 1.31-9.03). In FTD patients, ischemic heart disease and atrial fibrillation or flutter significantly predicted death (HR = 2.11; 95% CI = 1.08-4.14 and HR= 3.15; 95% CI = 1.60-6.22, respectively). Conclusion: Our study highlights differences in the occurrence and prognostic significance of cardiovascular diseases in several dementia disorders. This has implications for the care and treatment of the different dementia disorders.

- AimsHeart failure (HF) and dementia frequently coexist, but little is known about their types, relationships to each other and prognosis. The aims were to (i) describe patients with HF and dementia, assess (ii) the proportion of specific dementia disorders in types of HF based on ejection fraction and (iii) the prognostic role of types of HF and dementia disorders. Methods and resultsThe Swedish Heart Failure Registry (RiksSvikt) and The Swedish Dementia Registry (SveDem) were record-linked. Associations between dementia disorders and HF types were assessed with multinomial logistic regression and survival was investigated with Kaplan-Meier analysis and multivariable Cox regression. We studied 775 patients found in both registries (55% men, mean age 82years). Ejection fraction was preserved in 38% of patients, reduced in 34%, and missing in 28%. The proportions of dementia disorders were similar across HF types. Vascular dementia was the most common dementia disorder (36%), followed by other dementias (28%), mixed dementia (20%), and Alzheimer disease (16%). Over a mean follow-up of 1.5years, 76% of patients survived 1year. We observed no significant differences in survival with regard to HF type (P=0.2) or dementia disorder (P=0.5). After adjustment for baseline covariates, neither HF types nor dementia disorders were independently associated with survival. ConclusionsHeart failure with preserved ejection fraction was the most common HF type and vascular dementia was the most common dementia disorder. The proportions of dementia disorders were similar across HF types. Neither HF types nor specific dementia disorders were associated with survival.

- Objectives: We aimed to (1) study factors that determine the use of invasive procedures in the management of acute myocardial infarction (AMI) in patients with dementia and (2) determine whether the use of invasive procedures was associated with their better survival. Design: Cohort study based on patients registered in the Swedish Dementia Registry (SveDem), 20072012. Median follow-up time was 228 days. Setting: Patients diagnosed with dementia in specialist memory clinics and primary care units in Sweden. Participants: A total of 525 patients with dementia who suffered AMI (mean age 89 years, 54% women). Measurements: Information on AMI and use of invasive procedures (coronary angiography and percutaneous coronary intervention) was obtained from Swedish national health registers. Binary logistic regression was applied to study associations of patients characteristics with the use of invasive procedures; odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Survival was analyzed with Kaplan-Meier curves; log-rank test was used to compare survival of patients who received an invasive procedure versus those who did not receive it. Cox regression was applied to study association of the invasive procedures with all-cause mortality; hazard ratios (HRs) with 95% CIs were calculated. Results: One hundred ten patients (21%) with dementia received an invasive procedure in the management of AMI. After multivariate adjustment, lower age and higher global cognitive status were associated with the use of invasive procedures. The invasively managed patients survived longer (P = .001). The use of invasive procedures was associated with a lower risk of all-cause mortality, adjusting for type of AMI and dementia disorder, age, gender, registration unit, history of AMI and comorbidity score (HR 0.35, 95% CI 0.21-0.59), or total number of drugs (HR 0.34, 95% CI 0.20-0.58). Conclusion: Age and cognitive status determine the use of invasive procedures in patients with dementia. This study suggests that the invasive management of AMI has a benefit for survival of patients with dementia. (C) 2016 AMDA - The Society for Post-Acute and Long-Term Care Medicine.

Tidskriftsartikel (refereegranskat)abstract
- Background: Trends in the use of antithrombotic drugs in elderly patients with atrial fibrillation (AF) are largely unknown. We estimated the prevalence of AF in an older population, and examined whether use of anticoagulant and antiplatelet drugs in older AF patients has changed over time. Methods: Data from the population-based Swedish National study on Aging and Care in Kungsholmen (n = 3363, age = 60 years, 64.9% women) were used (2001-2004 and 2007-2010). AF cases were identified through 12-lead electrocardiogram, physician examinations, and patient register records (ICD-10 code I48). We used the CHADS(2) and CHA(2)DS(2)-VASc scores to estimate stroke risk, and an incomplete HAS-BLED score to estimate bleeding risk. Results: At baseline (2001-2004), 328 persons (9.8%) were ascertained to have AF. The prevalence of AF increased significantly with age from 2.8% in people aged 60-66 years to 21.2% in those = 90 years, and was more common in men than in women (11.2% vs. 9.0%). Among AF patients with CHADS2 score = 2 at baseline, 25% were taking anticoagulant drugs and 54% were taking antiplatelet drugs. High bleeding risk was significantly associated with not using anticoagulant drugs in AF patients (multi-adjusted OR = 2.50, p = 0.015). Between 2001-2004 and 2007-2010, use of anticoagulant drugs increased significantly, especially in AF patients with CHA2DS2-VASc score >= 2 (23% vs. 33%, p = 0.008) and in those with HAS-BLED score <3 (32% vs. 53%, p = 0.004). Conclusion: AF is common among old people. The use of anticoagulant drugs increased over time in AF patients, yet still two-thirds of those with high stroke risk remained untreated.

- ObjectiveTo examine the association of atrial fibrillation (AF) with cognitive decline and dementia in old age, and to explore the cognitive benefit of antithrombotic treatment in patients with AF.MethodsThis population-based cohort study included 2,685 dementia-free participants from the Swedish National Study on Aging and Care in Kungsholmen, who were regularly examined from 2001-2004 to 2010-2013. AF was ascertained from clinical examination, ECG, and patient registry. Global cognitive function was assessed using the Mini-Mental State Examination. We followed the DSM-IV criteria for the diagnosis of dementia, the NINDS-AIREN (National Institute of Neurological Disorders and Stroke and Association Internationale pour la Recherche et l'Enseignement en Neurosciences) criteria for vascular dementia, and the NINCDS-ADRDA (National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association) criteria for Alzheimer disease. Data were analyzed using multiple linear mixed-effects and Cox regression models.ResultsWe identified 243 participants (9.1%) with AF at baseline. During the 9-year follow-up period, 279 participants (11.4%) developed AF and 399 (14.9%) developed dementia. As a time-varying variable, AF was significantly associated with a faster annual Mini-Mental State Examination decline (beta coefficient = -0.24, 95% confidence interval [ CI]: -0.31 to -0.16) and an increased hazard ratio (HR) of all-cause dementia (HR = 1.40, 95% CI: 1.11-1.77) and vascular and mixed dementia (HR = 1.88, 95% CI: 1.09-3.23), but not Alzheimer disease (HR = 1.33, 95% CI: 0.92-1.94). Among people with either prevalent or incident AF, use of anticoagulant drugs, but not antiplatelet treatment, was associated with a 60% decreased risk of dementia (HR = 0.40, 95% CI: 0.18-0.92).Conclusion AF is associated with a faster global cognitive decline and an increased risk of dementia in older people. Use of anticoagulant drugs may reduce dementia risk in patients with AF.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: To identify sex-specific associations between risk factors and injurious falls over the short (<4 years) and long (4-10 years) term.DESIGN: Longitudinal cohort study between 2001 and 2011.SETTING: Swedish National Study on Aging and Care, Kungsholmen, Sweden.PARTICIPANTS: Community-dwelling adults aged 60 and older (N = 3,112).MEASUREMENTS: An injurious fall was defined as a fall that required inpatient or outpatient care. Information was collected on participant and exposure characteristics using structured interviews, clinical examinations, and physical function tests at baseline.RESULTS: The multivariate model showed that, in the short term, living alone (hazard ratio (HR)=1.83, 95% confidence interval (CI)=1.13-2.96), dependency in instrumental activities of daily living (IADLs) (HR=2.59, 95% CI=1.73-3.87), and previous falls (HR=1.71, 95% CI=1.08-2.72) were independently associated with injurious falls in women. Low systolic blood pressure (HR=1.96, 95% CI=1.04-3.71), impaired chair stands (HR=3.00, 95% CI=1.52-5.93), and previous falls (HR=2.81, 95% CI=1.32-5.97) were associated with injurious falls in men. Long-term risk factors were underweight (HR=2.03, 95% CI=1.40-2.95), cognitive impairment (HR=1.49, 95% CI=1.08-2.06), fall-risk increasing drugs (HR=1.67, 95% CI=1.27-2.20 for >= 2 drugs), and IADL dependency (HR=1.58, 95% CI=1.32-5.97) for women and smoking (HR=1.71, 95% CI=1.03-2.84), heart disease (HR=2.20, 95% CI=1.5-3.24), impaired balance (HR=1.68, 95% CI=1.08-2.62), and a previous fall (HR=3.61, 95% CI=1.98-6.61) for men.CONCLUSION: Men and women have different fall risk profiles, and these differences should be considered when developing preventive strategies. Some risk factors were more strongly predictive of injurious falls over shorter than longer periods and vice versa, suggesting that it may be possible to identify older men and women at short-and long-term risk of injurious falls.

- Background: Although falls in older adults are related to multiple risk factors, these factors have commonly been studied individually. We aimed to identify risk profiles for injurious falls in older adults by detecting clusters of established risk factors and quantifying their impact on fall risk. Methods: Participants were 2,566 people, aged 60 years and older, from the population-based Swedish National Study on Aging and Care in Kungsholmen. Injurious falls was defined as hospitalization for or receipt of outpatient care because a fall. Cluster analysis was used to identify aggregation of possible risk factors including chronic diseases, fall-risk increasing drugs (FRIDs), physical and cognitive impairments, and lifestyle-related factors. Associations between the clusters and injurious falls over 3, 5, and 10 years were estimated using flexible parametric survival models. Results: Five clusters were identified including: a healthy, a well-functioning with multimorbidity, a well-functioning, with multimorbidity and high FRID consumption, a physically and cognitively impaired, and a disabled cluster. The risk of injurious falls for all groups was significantly higher than for the first cluster of healthy individuals in the reference category. Hazard ratios (95% confidence intervals) ranged from 1.71 (1.02-2.66) for the second cluster to 12.67 (7.38-21.75) for the last cluster over 3 years of follow-up. The highest risk was observed in the last two clusters with high burden of physical and cognitive impairments. Conclusion: Risk factors for injurious fall tend to aggregate, representing different levels of risk for falls. Our findings can be useful to tailor and prioritize clinical and public health interventions.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: In a patient with clinically significant hyponatremia without other clear causes, thiazide treatment should be replaced with another drug. Data describing to which extent this is being done are scarce. The aim of this study was to investigate sociodemographic and socioeconomic factors that may be of importance for the withdrawal of thiazide diuretics in patients hospitalized due to hyponatremia.METHODS: The study population was sampled from a case-control study investigating individuals hospitalized with a main diagnosis of hyponatremia. For every case, four matched controls were included. In the present study, cases (n = 5204) and controls (n = 7425) that had been dispensed a thiazide diuretic prior to index date were identified and followed onward regarding further dispensations. To investigate the influence of socioeconomic and sociodemographic factors, multiple logistic regression was used.RESULTS: The crude prevalence of thiazide withdrawal for cases and controls was 71.9% and 10.8%, respectively. Thiazide diuretics were more often withdrawn in medium-sized towns (adjusted OR, 1.52; 95% CI, 1.21-1.90) and rural areas (aOR, 1.81; 95% CI, 1.40-2.34) compared with metropolitan areas and less so among divorced (aOR, 0.72; 95% CI, 0.53-0.97). However, education, employment status, income, age, country of birth, and gender did not influence withdrawal of thiazides among patients with hyponatremia.CONCLUSIONS: Thiazide diuretics were discontinued in almost three out of four patients hospitalized due to hyponatremia. Educational, income, gender, and most other sociodemographic and socioeconomic factors were not associated with withdrawal of thiazides.

Forskningsöversikt (refereegranskat)abstract
- Inappropriate drug use is an important health problem in elderly persons. Beginning with the Beers' criteria in the early 1990s, explicit criteria have been extensively used to measure and improve quality of drug use in older people. This article describes the Swedish indicators for quality of drug therapy in the elderly, introduced in 2004 and updated in 2010. These indicators were designed to be applied to people aged 75 years and over, regardless of residence and other characteristics. The indicators are divided into drug specific, covering choice, indication and dosage of drugs, polypharmacy, drug-drug interactions (DDIs), drug use in decreased renal function and in some symptoms; and diagnosis specific, covering the rational, irrational and hazardous drug use in common disorders in elderly people. During the 10 years since introduction, the Swedish indicators have several applications. They form the basis for recommendations for drug therapy in older people, are implemented in prescribing supports and drug utilisation reviews, are used in national benchmarking of the quality of Swedish healthcare and have contributed to initiatives from pensioner organisations. The indicators have also been used in several pharmacoepidemiological studies. Since 2005, there have been signs of improvement of the quality of drug prescribing to elderly persons in Sweden. For example, the prescribing of drugs that should be avoided in older persons decreased by 36 % between 2006 and 2012 in persons aged 80 years and older. Similarly, drug combinations that may cause DDIs decreased by 26 % and antipsychotics by 41 %. The indicators have likely contributed to this.
