About
Randal Zhou is a surgical outcomes researcher whose work focuses on the comparative effectiveness of operative approaches in hernia repair and bariatric surgery. His major contributions center on leveraging large national databases—including the Abdominal Core Health Quality Collaborative (ACHQC) and the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP)—to evaluate post-operative outcomes across open, laparoscopic, and robotic techniques. In his most cited study (8 citations), Zhou compared outcomes for large direct inguinal hernia repairs by operative approach, providing critical evidence for surgical decision-making. His 2022 analysis of robot-assisted sleeve gastrectomy (6 citations) examined staple line treatment modalities over a five-year period, advancing understanding of safety and efficacy in bariatric procedures. More recently, Zhou has investigated health equity in ventral hernia repair, exploring access and outcomes disparities for non-Hispanic Black versus white patients in the robotic surgery era. His work consistently addresses real-world surgical practice, using propensity score-adjusted methods to minimize bias. With a growing citation record and a focus on both clinical outcomes and health disparities, Zhou is establishing himself as a thoughtful contributor to evidence-based surgery and health services research.
