Stroke after Hospitalization: Assessment of Functional Prognosis through Disability and Dependency in CNHU-HKM, Cotonou, Benin

Abstract

Introduction: Stroke results in severe disability, with impacts that are sometimes socially, emotionally or professionally dramatic and also dramatic for the cost involved in care and treatment. Objective: Assessing the functional prognosis after hospitalization and identifying associated factors. Method: It consisted in a cross-sectional, prospective, descriptive and analytical study that was conducted from April 1 to August 31, 2013 in the Neurology Department of CNHU-HKM in Cotonou. It involved 100 patients who have known stroke for at least 6 months and were all admitted and discharged later on. The disease survivors were re-contacted and examined again at home or at hospital. Disability and dependency were then measured respectively with the Rankin score and Barthel index. The STATA/IC11.0 statistical software was used as the basis for data analysis. Unvaried and multi-varied analyzes helped to identify associated factors. Results: The overall disability and dependency rates were respectively 69% and 57.7%. And the highest rate of disability (38.8%) was observed between 50 and 60 years old. However, dependency prevalence was higher in subjects above 70 years old (37.3%). Regarding gender, the prevalence of disability was 59.2% in men and rather 41.5% in women. Predictors of disability and dependency were paralysis on admission (IC95% = 0.26 [0.77-0.92]; p = 0.036), obesity (IC95% = 0.26 [0.77-0.92]; p = 0.012) and monthly income lower than 70$US (IC95% = 0.05 [0.01-0.56]; p = 0.015). Conclusion: This study enabled
