RESUMO
OBJECTIVE: To investigate how functional, social and personal factors are associated with self-perceived level of disability in the chronic phase of stroke in a Latvian stroke population. The consequences of stroke can vary greatly and often leads to long-term disability that, according to the WHO definitions, depends on the interaction between the person and his/her context. DESIGN: Cross-sectional study with retrospective data gathering. SETTING: Community-dwelling persons who received specialised in-patient rehabilitation after stroke in Latvia. PARTICIPANTS: Of 600 persons after stroke who were identified through hospital register and selected for the study, 255 were included in the analysis. PRIMARY AND SECONDARY OUTCOME MEASURES: The medical information and discharge data of the Functional Independence Measure (FIM) was extracted from medical records. Participants filled out a questionnaire on sociodemographic information and the WHO Disability Assessment Schedule 2.0 (WHODAS 2.0), either in Latvian or Russian, depending on their wish when contacted for their oral agreement to participate. Stepwise multiple regression analysis was conducted to find a model that best explains the variance in WHODAS 2.0 scores. RESULTS: The models explained 23-43.5% of variance in outcomes. The best explained WHODAS 2.0 domains were 'mobility' and 'self-care'. The significant factors were level of independence in 'self-care', 'locomotion' and 'communication' according to FIM, as well as working status, time since rehabilitation, age, gender, living alone or in family and preferred language. CONCLUSIONS: Functional, social and personal factors are of similar importance when explaining self-perceived disability in the chronic phase of stroke. Some, but not all, of the factors are modifiable by the healthcare system. Therefore, a complex approach and involvement of medical, social and political systems is needed.
