Introduction: Coma is a medical emergency, and optimal management, especially in a resource-poor setting, depends on knowledge of its aetiology and predictors of outcome. This study aimed to provide hospital-based data on the prevalence, etiology, and outcome of non traumatic coma (NTC) in adults at a tertiary level in Cameroon. Methods: A three year retrospective cohort study of medical records of patients aged 18 years and above, who presented in coma of non-traumatic origin at a Cameroon emergency department (ED) was conducted. Data related to sociodemographic, clinical findings, investigations, etiology of the coma, and outcomes were collected. Results: A total of 408 patients were recruited, 214 (52.5 %) were males. The mean age was 55.9 ± 16.6 years. NTC accounted for 2.2 % of all consultations at the ED during the period of study. Stroke (29.6 %), infections (19.8 %), and metabolic disorders (12.6 %) were the most frequent cause of NTC. Etiology was unknown in 23.3 % of our participants. The in-hospital mortality was 66.4 %. Duration of hospitalization ≤ 3 days, GCS 〈 6, serum creatinine level 〉 13 mg/L, and administration of adrenergic drugs were predictors of mortality. Overall survival rate was 44.3 % after 5 days of admission. Conclusion: Non-traumatic coma had various aetiologies. Stroke accounted for almost one third of cases. About three out of five patients died in hospital. Deep coma, high serum creatinine level, short hospital stay and administration of adrenergic medications were independent predictors of mortality. |
