Purpose: Delayed complications (e.g., bleeding) of gastrointestinal endoscopy are often difficult to track. Mayo Clinic Rochester (MCR) tracks post-endoscopy complications via an automated reporting system, in which any patient hospitalized within seven days of an endoscopy is reviewed by the infection control service, as well as voluntary reporting by Mayo medical staff and patient self-report cards. We report here on our experience in attempting to augment physician reporting via weekly email reminders. Methods: Starting August 17, 2009, all attending physicians on hospital, consult and bleed-team services began receiving weekly email reminders asking them to report any post-endoscopy complications encountered during the week. Fourteen weeks later on November 23, 2009, gastroenterology fellows on the same services were added to the weekly email distribution list. All post-endoscopy complications were recorded along with the source of the information. The 42-week study period reported here was comprised evenly of 14 weeks prior to any email intervention, 14 weeks after the onset of the attending physician reminders, and 14 weeks of joint attending/fellow reminders. Results: In the first 14-week period, post-endoscopy complications were reported by 2 attending physicians and no fellows. After the onset of attending physician reminders, 11 attendings and 1 fellow reported post-endoscopy complications in the next 14 weeks. In the final 14-week period, during which both attendings and fellows received the email reminders, post-endoscopy complications were reported by 10 attending physicians and 6 fellows. Non-physician reporting rose during the three 14-week periods as well, with 11, 21, and 28 reports, respectively. Conclusion: Despite the difficulties in capturing post-endoscopy complications, an email reminder system worked well in increasing the contributions of attending physicians and GI fellows. The system is inexpensive and easy to implement. It is unclear whether the email reminders impacted post-endoscopy reporting by non-physicians.Figure
