Key result
Regional anaesthesia was associated with lower 28-day postoperative mortality (AHR 0.18; 95% CI 0.05-0.62), whereas age ≥65, ASA III/IV, emergency surgery, and SpO2 <95% were associated with higher risk.
Why the study?
The study aimed to assess the incidence and identify predictors of perioperative mortality among adults at Tibebe Ghion Specialised Hospital in Ethiopia.

High perioperative mortality with identified predictors in this Ethiopian cohort warrants targeted risk assessment; leaves open whether interventions improve outcomes.

What are the incidence and predictors of perioperative mortality among adults undergoing surgery in a low-resource setting?
Hazard Ratio: 0.18 (95% CI 0.05–0.62)
In a low-resource setting in Ethiopia, perioperative mortality is significantly predicted by older age, higher ASA physical status, emergency surgery, and low preoperative oxygen saturation.
Endeshaw et al. (2023) conducted a cohort in Surgery (n=2,530). Regional anaesthesia was evaluated on Time to death measured in days from immediate postoperative time up to the 28th day following surgery (AHR 0.18, 95% CI 0.05 to 0.62). Regional anaesthesia was associated with lower 28-day postoperative mortality (AHR 0.18; 95% CI 0.05-0.62), whereas age ≥65, ASA III/IV, emergency surgery, and SpO2 <95% were associated with higher risk.
