Background: The aim of this study was to examine the course of poststroke fatigue in a cohort of first-time stroke patients compared to the general population, and to identify clinically relevant features of post-stroke fatigue. Methods: We performed a follow-up study of 165 patients with first-time stroke admitted to acute stroke units at the Aarhus University Hospital, Denmark. A reference group of 1,069 persons was sampled from the general population. Fatigue was assessed using the Multidimensional Fatigue Inventory (MFI-20) covering five scales of fatigue (General Fatigue, Physical Fatigue, Reduced Activity, Reduced Motivation, and Mental Fatigue). Results: Compared to the general population, stroke patients reported higher levels of Physical Fatigue. Minor or no differences were found for the other fatigue scales. Pathological fatigue, defined as a score ≧12 on the General Fatigue scale, was reported by 59% (95% CI: 51–66%), 44% (95% CI: 36–51%), 38% (95% CI: 31–46%), and 40% (95% CI: 32–48%) of stroke patients 10 days, 3 months, 1 year, and 2 years following hospitalization for stroke, respectively. Post-stroke fatigue levels decreased after three months and remained stable throughout the remainder of follow-up. Poor functional outcome was consistently associated with increased levels of fatigue. Conclusions: Post-stroke fatigue is a common condition primarily characterized by increased levels of Physical Fatigue. The pathological mechanisms underlying post-stroke fatigue and its clinical implications require further study.
Background Real-world data of disease prevalence represents an important but underutilised source of evidence for health economic modelling. Aims The aim of this study was to estimate nationwide prevalence rates and summarise the characteristics of 199 chronic conditions using Danish population-based health registers, to provide an off-the-shelf tool for decision makers and researchers. Methods The study population comprised all Danish residents aged 16 years or above on 1 January 2013 (n = 4,555,439). The study was based on the linkage of national registers covering hospital contacts, contacts with primary care (including general practitioners) and filled-in out-of-hospital prescriptions. Results A total of 65.6% had one or more chronic condition. The ten conditions with the highest degree of prevalence were hypertension (23.3%), respiratory allergy (18.5%), disorders of lipoprotein metabolism (14.3%), depression (10.0%), bronchitis (9.2%), asthma (7.9%), type 2 diabetes (5.3%), chronic obstructive lung disease (4.7%), osteoarthritis of the knee (3.9%) and finally osteoporosis (3.5%) and ulcers (3.5%) in joint tenth place. Characteristics by gender, age and national geographical differences were also presented. Conclusions A nationwide catalogue of the prevalence rates and characteristics of patients with chronic conditions based on a nationwide population is provided. The prevalence rates of the 199 conditions provide important information on the burden of disease for use in healthcare planning, as well as for economic, aetiological and other research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
