Background: Surgical outcomes research is limited in areas of the world with the greatest unmet surgical need and likely greatest variation in outcomes. Measurement alone may improve outcomes-the so-called Hawthorne effect. The purpose of this multicenter cohort study was to identify factors that are both feasible to collect and are associated with a major adverse event following a targeted procedure in Cape Town, South Africa.
Methods: A collaborative of four acute care surgical units was formed to develop a data set with minimal data burden describing outcomes after an emergency exploratory laparotomy during a 3-mo period (February-April 2015). Controlling for patient, problem, provider, procedure and process predictors, multivariate models were built to identify risk factors for a major adverse event and higher resource use after surgery in our collaborative.
Results: The outcomes of 450 exploratory laparotomies from the four participating hospitals were audited, 319 (70.9%) were for non-trauma and 131 (29.1%) were for trauma. The major adverse event rate was 15.7% (95% CI 12.6-19.4). In the multivariate analysis, factors associated with the primary outcome included age, American Society of Anesthesia score of greater than 2, bowel resection, preoperative CT scan, and a nontherapeutic laparotomy. A major adverse event was associated with all three outcomes assessing increased resource utilization.
Conclusions: This study supports the comparative outcome assessment of a high-volume or high-risk procedure as a proxy for measuring the quality of care provided in a surgical collaborative. Such an exercise can identify opportunities for quality improvement.
