About
Ajay Aggarwal is a leading health services researcher whose work sits at the intersection of surgical oncology, health policy, and patient outcomes. His research primarily focuses on prostate and colorectal cancer, investigating how hospital organisation, competition, and technology adoption shape patient care and outcomes. Aggarwal’s landmark 2017 study on patient choice and hospital competition in cancer surgery (100 citations) demonstrated how market forces influence service configuration and technology uptake, providing critical evidence for healthcare policy. He has made seminal contributions to the debate on robotic surgery, with multiple highly-cited papers (61, 37 citations) comparing robot-assisted, laparoscopic, and open radical prostatectomy, revealing nuanced differences in functional outcomes and complications. His work on patient mobility for cancer surgery (43 citations) and hospital volume-outcome relationships (13 citations) has informed service centralisation policies. As a key figure in the National Prostate Cancer Audit, Aggarwal has helped develop robust performance indicators for surgical quality. His research combines rigorous population-based methodology with patient-reported outcomes, offering actionable insights for clinicians, policymakers, and patients navigating complex cancer care decisions.
