Association between surgeon age and surgical complications: A systematic review and meta-analysis

This meta-analysis synthesizes evidence on the relationship between surgeon age and surgical complications, incorporating 2.3 million procedures by 72,000 surgeons. Using PRISMA guidelines, we analyzed studies from 1990 to 2024 across multiple surgical specialties. Results demonstrate a U-shaped relationship between surgeon age and complications, moderated by surgical volume and specialty. High-volume surgeons maintained consistent outcomes until age 70, while low-volume surgeons showed significant age effects after 55. Complex procedures demonstrated stronger age effects than minimally invasive ones. Findings support individualized assessment over age-based policies, emphasizing the importance of volume maintenance and continuous education.
