About
Marianne Kit Har Au is a health economist and surgical outcomes researcher whose work focuses on the cost-effectiveness of minimally invasive and robotic surgical techniques. Her major contributions lie in systematically comparing the economic efficiency of open, laparoscopic, and robotic approaches across colorectal, liver, and pancreatic surgeries. Her most-cited paper, a 2023 systematic review and Bayesian network meta-analysis on colorectal surgery, has garnered 36 citations, establishing a benchmark for evaluating surgical value. She has extended this methodology to liver resection and distal pancreatectomy, producing similarly impactful analyses in 2024. Au’s research is notable for its rigorous application of network meta-analysis to synthesize evidence on both clinical outcomes and economic costs, providing crucial data for healthcare decision-makers. Her work directly addresses the pressing question of whether the higher upfront costs of robotic surgery are justified by improved patient outcomes or reduced long-term expenses. By quantifying trade-offs between surgical approaches, Au helps shape evidence-based policy and surgical practice, making her a key voice in the ongoing debate over technology adoption in surgery.
