Completion Rates and Timeliness of Diagnostic Colonoscopies for Rectal Bleeding in Primary Care.

Significant numbers of patients presenting to primary care with rectal bleeding fail to undergo recommended workup. The majority either have no procedure ordered, or procedure ordered but never scheduled or cancelled and not kept, suggesting these are important failure modes to target in future interventions. Ensuring reliable ordering and processes for timely scheduling and completion of procedures represent critical areas for improving the diagnostic process for patients with rectal bleeding in primary care.
