171 PROSPECTIVE EVALUATION OF THE TIMING OF POST-PROCEDURE PHONE CALLS TO PATIENTS IN DETERMINING THE TRUE RATE OF ADVERSE EVENTS FOLLOWING ERCP

Abstract

ERCP is a high risk endoscopic procedure, yet reports of ERCP related complications are largely limited to early adverse events, based on immediate post-procedure assessment. Many institutions attempt to follow-up with patients by telephone 1 day post-procedure; however this practice may successfully reach as few as 20% of patients, due to patient unavailability and staffing limitations. Based on population-level studies reporting that ERCPs result in a >10% rate of unplanned healthcare encounters (UHE) in the month following the procedure, we hypothesize that one-day follow-up calls underestimate the true adverse event rate, and later follow-up calls may enable a more accurate assessment of adverse events, leading to enhanced post-procedural patient care.
