Summary
An audit of 10,592 surgeries revealed an overall mortality rate of 7.55 per 1000 operations. Of these, 3.3 per 1000 operations were avoidable deaths, highlighting areas for surgical and anesthetic improvement.
Area of Science:
- Medical Auditing
- Surgical Outcomes
- Public Health in Central Africa
Background:
- Surgical safety and patient outcomes are critical in resource-limited settings.
- A comprehensive audit is essential for identifying systemic issues in healthcare delivery.
- Central African teaching hospitals face unique challenges in surgical care.
Purpose of the Study:
- To audit surgical operations and associated mortality in a Central African teaching hospital.
- To determine the overall and avoidable mortality rates.
- To identify factors contributing to avoidable deaths in surgical patients.
Main Methods:
- Retrospective audit of 10,592 consecutive surgical operations over 7 months.
- Classification of deaths as avoidable or unavoidable based on evidence of mismanagement.
- Categorization of avoidable factors into surgical, anesthetic, and administrative causes.
Main Results:
- Overall mortality rate (OMR) was 7.55 per 1000 operations (80 deaths).
- Avoidable mortality rate (AMR) was 3.3 per 1000 operations (35 deaths).
- Identified surgical, anesthetic, and administrative factors contributed to avoidable deaths.
Conclusions:
- A significant proportion of surgical deaths in this setting were potentially avoidable.
- Combined surgical and anesthetic audits are valuable for improving patient safety.
- Implementing targeted interventions can reduce avoidable mortality in similar healthcare environments.
