Knowledge of Stroke and its Risk Factors among Stroke Survivors: A Hospital Based Study

Significant variations observed in stroke incidence, risk factors and sufferings between high & resource poor countries. Considering lack of study in our country perspective, the study was designed to assess the knowledge of stroke and its risk factors among stroke survivors in Bangladeshi population. This hospital based cross-sectional study was conducted at the Department of Medicine and Department of Neurology in Uttara Adhunik Medical College & Hospital (UAMCH), Dhaka, Bangladesh. Patients aged >18 years who were admitted with stroke (Ischemic and hemorrhagic) were included in the study. Before enrollment informed consent was ensured. Total 50 patients were interviewed and assessed. Separate case record form was used during data collection. Final analysis was done by SPSS 22.00 version software. A 'good' knowledge of stroke was defined by correct answer to ≥4 out of 7 questions about location, cause, risk factor, warning sign, treatment, complication and prevention of stroke. Among 50 stroke survivors, mean age was 58.34±12.90 (SD) years. Male-female ratio was 1.08:1. Overall 78% patients had good knowledge of stroke. Brain was correctly identified as center of stroke by 52% stroke survivors and disturbance of blood supply to brain as a cause of stroke was recognized by 12%. Stress was the most common risk factor identified (50%). At least one warning sign was identified by 76% stroke survivors. Seventy-four percent stroke survivors knew that they have to be taken to nearest health facility and if possible, in hospital where neurological care is available. Only 4% knew about the golden hour of taking the stroke patient. On average knowledge about treatment, complication and prevention of stroke was good. Stroke knowledge was not significantly associated with demographic and socio-economic profile of stroke survivors. More than two thirds of the patients had knowledge regarding stroke and its risk factors but no uniform pattern of knowledge is noticed.
