Accreditation by the Commission on Cancer (CoC) is linked to improved survival outcomes in colorectal cancer patients, highlighting the significance of quality care indicators.

• CoC-accredited hospitals showed reduced 5-year mortality hazards: high-tier hospitals (HR 0.63) had significantly lower mortality than medium-tier, while low-tier hospitals had higher mortality (HR 1.51).
• Overall, treatment at CoC-accredited hospitals was associated with reduced 1-year mortality: high-tier hospitals (HR 0.81) and high-performing hospitals (HR 0.83) showed better outcomes.

Surgeons should consider referring patients to CoC-accredited facilities to optimize colorectal cancer care and enhance survival rates.
