OBJECTIVES: It is well-known that stroke is one of the primary causes of death with low survival rates in Turkey. This study investigates how many months a patient with stroke lives and which factors most influence survival in stroke in Turkey. METHODS: Based on Elixhauser Comorbidity Index, data for patients diagnosed at least with stroke or 17 chronic diseases such as hypertension, diabetes, heart diseases were collected from Turkish SocSecurity Institution database between 2008 and 2013. Then with simple random sampling method, a sample of 2,113 ischemic stroke and 155 hemorrhagic stroke patients were selected. Two Cox regression models were run to identify which factors impact the survival years and how much they reduce survival for each stroke type. Finally survival months were calculated. RESULTS: Among dead patients, a patient with stroke lived less than a year on average. 14%, 11%, 11% and 14% percent of stroke patients died 1-2 years, 2-3 years, 3-4 years and more than 4 years respectively. In the first model the average survival month for an ischemic stroke patient was 35. Age and gender didn’t change survival months statistically. Hypertension, diabetes, heart disease and nervous system diseases reduced survival months by 4, 12, 7 and 9 months respectively with 95% confidence level. In the second model a hemorrhagic patient lived 39 months on average. A patient younger than 55 experienced 10 months longer lives than a patient over 55. Gender again didn’t incorporate any chance to survival. In addition, a patient with no hypertension and heart disease enjoyed 24 and 19 months longer lives respectively. CONCLUSIONS: In Turkey, the chance of living longer for ischemic stroke patients drops if the patients were diagnosed with hypertension, diabetes, heart disease or nervous system disease. Older patients with hemorrhagic stroke lived less, hypertension and heart disease adversely affected survival months.
