About

Lia D. Delaney is a surgical outcomes researcher whose work centers on patient-centered decision-making, health equity, and the adoption of advanced surgical technologies in hernia repair. Her major contributions illuminate how patients and surgeons navigate complex choices in abdominal wall surgery. In her landmark study on decision regret following elective hernia repair (17 citations), Delaney quantified the psychological toll of surgical choices, revealing that nearly one in five patients later regretted their operation—a finding that challenges surgeons to better align expectations with outcomes. She has also been a leading voice on sex disparities in ventral hernia repair (16 citations), demonstrating that women receive less aggressive treatment and experience worse outcomes, thereby exposing a critical gap in surgical care. Delaney’s mixed-methods analysis of robotic technique adoption (6 citations) uncovered wide surgeon-level variation, highlighting how operator preference—rather than evidence—often drives technology use. Through her work with a statewide quality improvement collaborative, she has shown that even for small hernias, surgical approaches vary dramatically, underscoring the need for standardized, evidence-based guidelines. With a growing portfolio of high-impact studies, Delaney is shaping a more equitable, patient-aware, and data-driven future for hernia surgery.
