Determinants of health-related quality of life in Nigerian stroke survivors

Summary 

Stroke is a leading cause of disability in developing countries. It is crucial to identify factors influencing health-related quality of life (HRQOL) in stroke survivors in this setting so that such factors can be efficiently manipulated in order to maximize HRQOL improvement. This is the first study of these determinants in Nigerian stroke patients. One hundred consecutive consenting stroke survivors were studied in Ibadan. The stroke levity scale (SLS) was used to assess stroke severity. HRQOL was assessed using the psychometrically robust HRQOL in stroke patients (HRQOLISP) questionnaire. HRQOL determinants were sought among variables such as age, gender, socio-economic class (SEC), post-stroke duration, side, type and number of strokes, SLS, modified Rankin scale (mRS), social support, and Likert-graded responses to laughter and negative feelings frequencies. Gender, aphasia, handedness, stroke side, type and frequency as well as SEC had no significant impact on HRQOL. The determinants of HRQOL were SLS, mRS, social support, laughter and negative feelings frequencies. Aside from stroke levity and disability, psychosocial factors such as emotional responses and social support determine HRQOL in stroke survivors. Both neuroscience and clinical management of stroke might benefit from a corresponding broader integrative conceptual framework for life after stroke.
