A NCDB analysis of >110K patients undergoing definitive resection of rectal adenocarcinoma at >1300 Commission on Cancer-accredited facilities demonstrates a reduction in the rate of not reporting circumferential resection margin status—a crucial determinant of subsequent therapy recommendations—from 16% in 2010 to 12% in 2019. Higher rates of failure to report were seen among academic facilities and among facilities failing to meet other quality metrics with no association with facility patient volume, suggesting this largely stems from a system not person problem. | Manisundaram, JAMA Surg 2023
