Is National Accreditation Program for Rectal Cancer (NAPRC) accreditation associated with changes in rectal cancer patient volume, procedural volume, and care fragmentation at accredited hospitals?In this difference-in-differences study, NAPRC accreditation was associated with a statistically significant increase of approximately 4 additional patients with rectal cancer per year at accredited centers compared with nonaccredited centers. Procedural volumes for early-stage (stage I) rectal cancer significantly increased, whereas procedural volumes for locally advanced (stage II/III) disease did not change, a pattern consistent with national treatment trends; accreditation was not associated with increased care fragmentation.In this study, NAPRC accreditation was associated with increased overall patient and early-stage procedural volumes without worsening care fragmentation, supporting its potential institutional and clinical value in rectal cancer care.
