Knowledge Regarding Basic Facts of Stroke Among Final Year MBBS Students and House Officers: A Cross-Sectional Survey of 708 Respondents from Pakistan

Abstract

INTRODUCTION: Stroke is the leading cause of neurological disability in the world. In Pakistan, house officers (HOs) are usually the first contact for a stroke patient in the emergency department. Sometimes they need to make quick decisions regarding diagnosis and management without specialist supervision. Thousands of current final year MBBS (Bachelor of Medicine, Bachelor of Surgery) students will be performing the duties of HOs soon. This study documents the knowledge and confidence levels of final year students and HOs in Pakistan regarding basic facts related to initial diagnosis and management of stroke. MATERIALS AND METHODS: A questionnaire was developed using two standard textbooks of medicine and current stroke guidelines of the American Heart Association. The pre-tested self-administered questionnaire was distributed among 800 final year MBBS students and HOs in 14 medical colleges and hospitals in four different cities. The response rate was 88.5%. Data analysis was done using SPSS V.21. The CMH Lahore Medical College Ethics Review Committee approved this project. RESULTS: Respondents included medical students (n=496) and HOs (N= 212); most were female (n = 452, 63.9%). Of these, 31.4% had managed or assisted in the management of a patient with a stroke and had a higher confidence level in its diagnosis (p< 0.001) and management (p <0.001). Having a family member with stroke was associated with higher confidence in the diagnosis of stroke (p < 0.05) but not with confidence in its management (p = 0.41). Most correctly defined stroke (60.6%), identified the CT scan as the initial diagnostic modality (88.1%), knew the dosage of aspirin (64.9%), knew the time limit for thrombolysis (67.4%), and were familiar with the risk of deep vein thrombosis in immobilized stroke patients (85.4%). Less than half (44.5%) chose tissue plasminogen activator (t-PA) as the preferred initial intervention for acute ischemic stroke. CONCLUSION: This multicenter survey shows that the knowledge and confidence of medical students and HOs in Pakistan regarding initial diagnosis and management of stroke are inadequate in most domains. There is a need to improve the medical training for stroke in emergency departments for optimal outcomes. Public education campaigns about stroke should be conducted to increase the general awareness of the population about the prevention, signs, symptoms, and emergency steps to be taken when encountering a case of stroke.
