Accreditation for rectal cancer is linked to higher patient volumes and early-stage procedures.

• Naprc-accredited hospitals saw an annual increase of 4.3 rectal cancer patients per institution.
• Accreditation boosted stage I procedure volume, with a gain of 1.01 procedures (p=0.05).

Improving accreditation may support institutional growth without sacrificing care quality.

• Care fragmentation remained unchanged, indicating continuity in patient management.
