Three-month outcome of patients operated for chronic subdural hematoma at four hospitals, Addis Ababa, Ethiopia, 2021GC

Background: Chronic subdural hematomas are a relatively common condition defined as an abnormal collection of blood and its break down products in the subdural space, usually accompanied by a history of preceding mild head trauma. Surgical management remains the mainstay of treatment. There are very few studies in Africa and Ethiopia on the area with most being retrospective. Objectives: To assess the three-month outcome of patients operated for CSDH at four hospitals in Addis Ababa, Ethiopia. Method: Institution-based prospective observational study was conducted among patients operated for symptomatic chronic subdural hematoma on 4 hospitals in Addis Ababa from November 1, 2020, to June 30th, 2021 G.C. Result: Out of 144 patients 56.9% were male, the predominant symptom was headache, 75% of them had trauma history and 46.5 % were within the age group of 55–74 years. On the 3-month follow-up, we had 6 deaths (4.2%); of these, only one died out of hospital. Four patients (2.8%) had GOS-E score of 5&6 and the rest (93.1%) had good recovery with GOS-E of 7 &8. Conclusion: Having low admission markwalder grading, being an alcohol abuser, and having post-operative complications will have an impact on the outcome of patients operated on for CSDH.
