About
Dr. Chia-Na Chang is a leading surgical outcomes researcher whose work has fundamentally reshaped our understanding of colorectal cancer treatment. Her primary research areas center on comparative effectiveness and health economics in surgical oncology, with a particular focus on the three main modalities: open, laparoscopic, and robotic surgery. Dr. Chang’s landmark 2017 study, which analyzed over 1.2 million patient records from the US National Inpatient Sample, provided the first comprehensive, population-level snapshot of surgical trends and outcomes for colorectal cancer from 2004 to 2012. This widely cited work (62 citations) revealed critical shifts in practice patterns and established a benchmark for evaluating surgical care. Building on this, her 2019 propensity score-matched analysis (32 citations) offered a rigorous comparison of outcomes and costs across the three approaches for colon cancer, delivering actionable evidence for surgeons and policymakers. By leveraging massive national databases, Dr. Chang has illuminated the real-world trade-offs between innovation, cost, and patient outcomes, making her a pivotal voice in evidence-based surgical decision-making.
