About
Yu-San Chien is a leading figure in surgical outcomes research, with a focus on comparing robotic-assisted procedures against traditional open and laparoscopic techniques. His work leverages large-scale, real-world data to provide definitive evidence on the safety and efficacy of minimally invasive surgery. Chien’s major contributions include two landmark, nationwide population-based cohort studies using Taiwan’s National Health Insurance Research Database (NHIRD). The first, on radical prostatectomy, rigorously compared perioperative outcomes, complications, and survival rates across open, laparoscopic, and robot-assisted approaches. The second, a propensity-weighted analysis of mitral valve replacement, evaluated mid-term survival, complications, and healthcare costs between robotic-assisted and conventional sternotomy. Though recently published in 2025, these studies have already garnered citations, signaling their immediate impact on clinical decision-making. By harnessing comprehensive national datasets, Chien provides high-level evidence that helps surgeons and hospitals weigh the benefits of robotic technology against traditional methods, ultimately guiding patient care and healthcare policy. His work is essential reading for anyone interested in the real-world outcomes of surgical innovation.
