Profile of Head Injuries: Prehospital Care, Diagnosis, and Severity in an Ethiopian Tertiary Hospital.

Background: Consistent data on head injury is lacking especially in the low- and middle-income countries. Our study tries to characterize patients with head injury at the emergency department of one of the few tertiary public hospitals giving neurosurgical care in the country.

Methods: A retrospective cross-sectional study was performed from May 2015 to October 2015 in one of the neurosurgical teaching hospitals, Black Lion Specialized Hospital. All adult patients with head injury who visited the emergency department during the study period were included. Data on patients' sociodemographic, mechanism of trauma, clinical presentation, imaging findings, and presence of polytrauma were collected by a pretested questionnaire. The source of data was emergency department logbooks and patient charts.

Results: A total of 390 patients with head injury who visited the emergency department were included during the study period. There were 335 males (85.9%) and 55 females (14.1%) with the mean age (standard deviation) of 35.4 (15.6) years. Majority of patients came by taxi constituting 149 (38.2%) of all patients, whereas 147 patients (37.7%) used ambulance. Of 147 patients brought by ambulances, 133 (90.4%) were referred from other hospitals. The majority, 26 (45.6%), of patients who came directly to the emergency department used taxis. It is shown that the mode of arrival and origin of arrival are significantly related, P = 0.000. Mortality of severe head injury at the emergency department was 50.8%.

Conclusions: Prehospital care coverage was low and ambulances were used mainly for interhospital transfers. Mortality of severe head injury at the emergency department is high and significantly associated with preventable causes like vital sign derangement.
