Predictive Factors of Mortality of Chronic Subdural Hematoma in Adults in Antananarivo Madagascar

Objective: To determine the poor prognostic factors of chronic subdural hematomas in the Neurosurgery Departments of the existing University Hospitals in Antananarivo, Madagascar. Methods: This was a multicenter, retrospective, cross-sectional, descriptive and analytical study of 125 cases of chronic subdural hematoma. Results: Poor prognostic factors for chronic subdural hematoma were age (OR: 4.4100; p = 0.005), male gender (OR: 4.354; p = 0.008), head injury (OR: 5.2250; p = 0.001), arterial hypertension (OR: 3.773; p = 0.028), ethylism (OR: 5.9639; p = 0.035), anticoagulant use (OR: 5.785; p = 0.001), altered general condition (OR: 3.4000; p = 0.001) and low Glasgow (OR: 14.444; p = 0.001). Conclusion: Identification of these mortality risk factors would be beneficial in improving and implementing appropriate management.
