Background — Endoscopists are advised to measure and report their rates of colonoscopy-associated perforation and bleeding. However, evidence from population-based studies is lacking on the time period over which monitoring is needed to detect these adverse events.
Objective — To determine the time course of perforation or bleeding requiring hospital admission within 30 days after outpatient colonoscopy.
Design — Population-based cohort study.
Setting — Ontario, Canada.
Patients and Intervention — Men and women, 50 to 75 years old who underwent an outpatient colonoscopy during the period from April 1, 2002 to March 31, 2003.
Main Outcome Measurements — Hospitalization for colonoscopy-related perforation or bleeding within 30 days after the procedure.Results —The researchers identified 67,632 patients who had an outpatient colonoscopy, of whom 37 were admitted for hospitalization with perforation and 83 with bleeding within 30 days after the procedure. For those with a perforation, 34 of 37 (92%) were admitted within 2 days and all within 5 days. For those with bleeding, 30 of 83 (36%) were admitted within 2 days and 80 of 83 (96%) within 14 days.
Limitations — Lack of information on medication use.
Conclusions — After outpatient colonoscopy, use of a 14-day time period for reporting would capture all perforations and the majority (96%) of bleeds requiring hospital admission.
