Pak J Med Health Sci Jan ;13(2):327-9.

Background: Stroke is one of the leading cause of disability as well as mortality throughout world. Multiple risk factors have different association with ischemic stroke and also different impact on length of stay in hospital . Aim : To identify the major risk factors in patients of first ever ischemic stroke and impact of National institute of health stroke scale score and Modified Barthel Index score on length of stay in hospital. Study design: Retrospective analysis Setting: Medical Unit of Teaching Hospital, University College of Medicine Lahore. Duration: 6 months (January-June 2018) Methods: We enrolled 87 patients in our study who were admitted in medical unit with ischemic stroke. All information sorted out from medical record of the patients. Age and length of hospital stay documented as mean +/- SD, risk factors as frequency and percentages. NIHSS and MBI score were noted. Data were analyzed in SPSS version 21. Relationship of NIHSS and MBI with length of hospital stay was determined using regression analysis . Results: A total 87 patients, age of 58.5 +/- 15 years, mean length of stay 3.8+/-3.1 days. Hypertension was found in 56%, smoking 37%, diabetes 24%, Ischemic heart disease 18%, atrial fibrillation 11% and valvular heart diseases in 3% cases. NIHSS score more than 16 was related to greater than 7 days stay in hospital in 85% cases while MBI score of less than 50 was associated with greater than 7 days stay in hospital in 92% cases showing significant results. Conclusion: Hypertension, smoking, diabetes and ischemic heart disease are risk factors for Ischemic stroke while high NIHSS and low MBI score are predictors of longer hospital stay in patients of acute ischemic stroke .
