About

Andrew J. Mullard is a leading surgical outcomes researcher whose work has fundamentally shaped our understanding of minimally invasive colorectal surgery. His key research areas include comparative effectiveness of laparoscopic versus robotic surgical techniques, surgical cost analysis, and risk stratification for operative conversion. Mullard’s major contributions center on large-scale, population-based analyses that provide evidence-based guidance for surgical decision-making. His landmark 2015 study, cited over 100 times, established critical benchmarks by directly comparing laparoscopic and robotic outcomes in colorectal surgery across a broad patient population. He further advanced the field by quantifying the clinical and economic implications of unplanned conversions, demonstrating that conversion from minimally invasive to open surgery carries significant cost and morbidity implications. Through his work with the Michigan Surgical Quality Collaborative database, Mullard identified specific patient and procedural risk factors that help surgeons predict and potentially avoid conversions. His research has been instrumental in helping hospitals and surgeons weigh the benefits and costs of adopting robotic platforms, making him a respected voice in the ongoing debate over surgical technology adoption.
