Background: Cerebrovascular accident (CVA) is a problem that refers to a group of conditions that affect the circulation of blood to the brain. The objective of this study was to identify factors related to cerebrovascular accident patients in the Ayder Comprehensive Specialized Hospital. Method: A retrospective cohort study design was conducted in the Ayder Comprehensive Hospital from January 2015 to August 2016 and followed for a total of 20 days during the admission period. Data was collected from a database of electronic medical records and medical charts using a structured data extraction tool. Kaplan-Meier, log rank test and Cox-proportional hazard regression were used. STATA V.13 program was used for data entry, cleaning and analysis. Result: From 292 CVA case patients, 42(14.4%) died and (80.95%) were died with in the 7 days of hospital stay and their median survival time was also 7 days. Factors associated with CVA mortality were: positive history of hypertension (HR=4.8, 95%, CI= 1.486 – 16.018), positive history of diabetes mellitus (HR=2.0, 95%, CI= 1.086 – 3.789), Stroke sub type as haemorrhagic (HR= 2.1, 95%, CI= 1.070 – 4.160), admitted in intensive care unit (HR= 2.48, 95%, CI= 1.166 -5.306) and increased age (HR= 5.1, 95%, CI= 1.725 – 15.487) Conclusion: The risk rate of patients at an earlier time was high, and there was more death in the intensive care unit than any other medical wards. Hypertension was the most common risk factor for both types of cardiovascular accidents. Ischemic stroke subtype, diabetes mellitus and rising age were also associated survival factors.
