Semiautomated electronic medical record based system for monitoring delayed adverse events in pediatric endoscopy and sedation

Objective: To develop a semiautomated electronic medical record (EMR) system to track pediatric endoscopic procedural adverse event (AE) at a tertiary referral children's hospital. Methods: We developed an automated EMR based query for postprocedure AEs. Main outcome measurements within 30 days of procedure: return to emergency department, return to surgery, unplanned admissions and admissions with longer than intended stays. Events were graded using a recently described classification system for postendoscopy events and tracked for a 36-month period, from January 2017 to December 2019. Results: Development of a semi-automated system was successful in comprehensive identification of endoscopy and sedation related AE. A total of 193 AEs (2%) were identified in all three categories. Seventy cases (0.7%) were noted to be a direct result of an endoscopic procedure. Of these cases, 31 (44%) were noted to be Grade 3, 5 cases (7%) Grade 4, and no Grade 5 AE occured. Higher rates of AE were observed after therapeutic procedures versus diagnostic (2.6% vs. 0.3%, p = <0.00001). AEs related to sedation occurred in 0.5% of procedures with the majority (84%) reported in patients with American Society of Anesthesia classification of 3 or greater. Conclusions: Diagnostic endoscopy remains a safe procedure and risk of both endoscopy and sedation related AE are low. Therapeutic procedures carry a higher risk but are still overwhelmingly safe. Institutional investment in this EMR based system allowed for sustainability and comprehensive tracking of endoscopy related AE.
