The Burden of Neurosurgical Diseases in a Rural Southwestern Nigeria Setting

Abstract

Background: Most of the few neurosurgeons in Nigeria are clustered in the urban centers. Consequently, a large proportion of the population who live in the rural areas have no direct access to neurosurgical care. This study aims to describe the burden of neurosurgical diseases in a rural neurosurgical service in Nigeria.

Methods: This was a prospective observational study of all neurosurgical patients managed at our center between August 2018 and July 2019. Data were analyzed with SPSS version 20 (IBM, Armonk, New York, USA).

Results: The study cohort comprised 379 patients, including 267 males and 112 females (male:female ratio 2.4:1). The mean age was 35.71 ± 20.08 years (range, 35 hours to 100 years). More than one-half of the patients (55.6%) were age 20-49 years. Head injury was the most common presentation, occurring alone in 256 patients (67.55%) and in combination with spinal cord injury in 30 patients (7.92%). Brain tumors were present in 19 patients (5.01%), spinal cord injury in 15 patients (3.96%), degenerative spine disease in 9 patients (2.38%), and hydrocephalus in 5 patients (1.32%). Surgical intervention was performed in 21 patients (5.54%). The outcome of treatment was good in 251 patients (66.22%); 34 patients (8.97%) were referred to other facilities, 43 patients (11.35%) were discharged against medical advice, mostly because of economic reasons and poor medical insight, and 31 patients (8.18%) died.

Conclusions: Trauma is the most common indication for neurosurgical care in our service. Poverty and poor medical insight remain formidable obstacles to maximizing the benefits of available neurosurgical care in developing countries.
