Abstract:
Introduction: Stroke is a worldwide health problem and a major contributor to mortality
and disability in both developing and developed countries. It is the third commonest
cause of death worldwide and the single largest cause of adult disability. It has been
estimated that by 2020, stroke will be the leading cause of lost healthy life-years.
Awareness of stroke is the major part of preventing the prevalence and complications of
stroke. The recognition of stroke symptoms by the public and activation of the
Emergency Medical Services (EMS) are the most important factors in initiating prehospital
stroke care.
Objective: The purpose of this study was to assess the knowledge regarding stroke
among hypertensive patients who were attending the medical clinic at Teaching Hospital
Batticaloa.
Method: A cross sectional descriptive study was conducted for one year among 269
hypertensive patients who were attending medical clinic. After obtaining written consent,
data were collected according to systematic sampling through a pre designed and pre
tested interviewer administered questionnaire. Statistical Package of Social Science 19
(SPSS v.19) was used for entering, analyzing and interpreting the data. The descriptive
analysis was employed in calculation of frequency and percentage and the association of
knowledge with demographical factors was assessed through Chi square test.
Results: Only 5.6 % hypertensive patients (n=15) had good knowledge, while many of
them (n=151) 56.1% had adequate knowledge regarding stroke. The most common risk
factors identified were hypertension (79.2%) and hyperlipidemia (40.1%). Sudden
numbness (85.1%) and weakness or paralysis of face, arms and limbs (67.3%) were the
commonly identified sign and symptoms. There was a significant association (p<0.05)
between the knowledge of stroke and the following background characteristics; place of
living, education, occupation, income, duration of hypertensive clinic follow up and
family history of stroke.
Conclusion: Knowledge on stroke among the patients was satisfactory in many aspects.
