Effect of Delayed Endoscopy Protocol on Timing and Safety of Endoscopy for Foreign Body Ingestion and Esophageal Food Impaction.

Abstract

Endoscopic procedures for foreign body ingestion (FBI) and esophageal food impactions (EFI) performed during on-call hours are associated with increased stress, risk, and cost. We implemented a Foreign Body Algorithm (FBA) designed to delay all but the most urgent endoscopy for EFI and FBI until regular working hours. Using endoscopy records from multiple academic and community hospitals within a large integrated health system in the United states, we identified esophagogastroduodenoscopy (EGD) performed for food impactions and foreign body ingestions occurring between May 2011 and February 2021. We identified 479 EGDs performed for FBI and EFI. The introduction of the FBA was associated with a shorter length of stay (LOS) for overall cases (0.35 vs. 0.8d P<0.001), day cases (0.16 vs. 1.0d P<0.001), and night cases (0.40 vs. 0.6d P=0.03). The introduction of the FBA did not change the rate of overall adverse events (AE) or night AE. AE from the entire cohort was rare (3%; 16 total). Of the AE, most were sedation related. The introduction of the FBA did not affect the overall rate of night cases or AE, but the rate of after-hours endoscopy for intentional ingestions decreased from 17.2% to 3.1% (P=0.01). This is one of the largest studies of esophageal impactions and foreign bodies in adults in the United States, and the first to examine the effects of a protocol designed to avoid after-hours endoscopy. These results suggest that postponing after-hours EGD until the daytime is not associated with adverse safety outcomes or increased LOS.
