A study conducted at the Akanda Military Teaching Hospital in Cameroon has shed light on the epidemiological, etiological, and outcome profile of severe coma cases in the intensive care unit. The research, which took place from January 2023 to December 2025, involved 44 patients hospitalized for severe coma. The findings indicate that severe coma is a common emergency in intensive care, with a high mortality rate, particularly in African settings.
According to the study, coma in adults accounted for 24.8% of intensive care admissions, with severe cases representing 8.57% of the total. The median age of onset was 51 years, with a male-to-female ratio of 1.58. Hypertension was the most common underlying condition, affecting 31.8% of patients, followed by diabetes at 18.2%, and HIV at 9.2%. These statistics highlight the need for targeted interventions to address these underlying conditions.
The study identified the etiologies for severe coma, which were vascular (45.5%), infectious (29.5%), traumatic (11.4%), metabolic (4.5%), and undetermined (9%). The high proportion of vascular and infectious causes suggests that preventing cardiovascular disease and combating the rise of transmissible infectious diseases are crucial to reducing the incidence and mortality of severe coma cases.
The prognosis for patients with severe coma was unfavorable in 90.9% of cases, indicating a high mortality rate. This finding underscores the need for improving intensive care services, including upgrading hospital facilities and enhancing the skills of healthcare professionals. The study's results have significant implications for healthcare policy and practice in Cameroon and other African countries.
The research used a descriptive retrospective study design, collecting data from medical records and analyzing it using Microsoft Office Excel 2021 and Epi Info version 7.2.5.0. The study's authors suggest that preventing cardiovascular disease, combating the rise of transmissible infectious diseases, and upgrading hospital facilities are essential to reducing the incidence and mortality of severe coma cases.
The study's findings are consistent with previous research on severe coma cases in Africa. For example, a study in Benin found that non-traumatic comas were a significant cause of intensive care admissions, while another study in the Democratic Republic of Congo identified similar etiologies for severe coma. These findings highlight the need for a regional approach to addressing the challenges of severe coma cases.
The study's authors emphasize that the emergence of cardiovascular and infectious diseases in Africa has established stroke and meningitis as leading causes of severe coma in adults requiring intensive care. They conclude that a multi-faceted approach is needed to address these challenges, including prevention, early detection, and effective management of severe coma cases.
Key points
- The study highlights the need for targeted interventions to address underlying conditions such as hypertension, diabetes, and HIV.
- The high mortality rate associated with severe coma cases underscores the need for improving intensive care services in African hospitals.
- Preventing cardiovascular disease and combating the rise of transmissible infectious diseases are crucial to reducing the incidence and mortality of severe coma cases.
