Prospective Observational Study of Intraoperative Anesthetic Events in District Hospitals in Namibia.

BACKGROUND: Access to safe surgery and anesthesia care is grossly inadequate in low- and middle-income countries, with a shortage of anesthesia providers contributing to this crisis. In Namibia, medical officers typically receive no >3 months of informal training in anesthesia. This study sought to determine the prevalence, currently unknown, of intraoperative adverse anesthetic events in this setting. Further, we assessed surgical volume, complications, and mortality outcomes at the district hospital level. METHODS: This was a prospective observational study over 7 months involving 4 district hospitals from geographically separate and diverse areas of Namibia. A standardized protocol was used to record adverse anesthetic events during surgery, surgical volume, and complications including mortality. RESULTS: A total of 737 surgical procedures were performed during the study period. There was a 10% prevalence of adverse anesthetic events intraoperatively. Of these, 70% were related to hypotension and 17% due to hypoxia and/or difficult/failed intubation. Ninety-eight percent of patients were classed as low risk (American Society of Anesthesiologists I or II). Seventy-two percent of the surgical workload was in obstetrics and gynecology, with over half being for urgent obstetrics. Perioperative mortality rate was 1.4/1000, with an overall surgical complication rate of 1.6% and a surgical infection rate of 0.8%. CONCLUSIONS: We found a 10% prevalence of adverse anesthetic events intraoperatively when anesthesia was administered by medical officers with no >3 months of informal training in this low-resource environment. The patients were considered low risk by the medical officers responsible for the anesthesia, yet these events had the potential to lead to patient harm.

The Bare Minimum: The Reality of Global Anaesthesia and Patient Safety.

INTRODUCTION: Current guidelines for the provision of safe anaesthesia from the World Health Organization and the World Federation of Societies of Anaesthesiologists (WFSA) are unachievable in a majority of low and middle-income countries (LMICs) worldwide. METHODS: Current guidelines for anaesthesia and patient safety provisions from the WHO and WFSA are compared with local ability to achieve these recommendations in LMICs. CONCLUSIONS: Influential international organizations have historically published anaesthesia guidelines, but for the most part, without impacting substantial documentable changes or outcomes in low-income environments. This analysis, and subsequent recommendations, reviews the effectiveness of existing strategies for international guidelines, and proposes practical, step-wise implementation of patient safety approaches for LMICs.
