Emergency department trends for inguinal hernia and gallbladder disease before and after COVID-19 scheduled surgery interruptions: lessons for hospital capacity management.

Abstract

Objectives: Postponing scheduled surgeries may alleviate emergency department (ED) crowding by increasing inpatient beds for ED patients but the impact of such measures are unclear. We determined if scheduled surgery cancellations for inguinal hernia and gallbladder disease during the coronavirus pandemic affected ED presentations, hospitalizations, and complications.

Methods: This database review included Albertans ≥ 18 with ED presentations for inguinal hernia and gallbladder disease from March 1, 2018 to May 31, 2022. The primary outcome examined ED hospitalizations and complications in the pre- (March 1, 2018-March 18, 2020) and post-cancellation (May 4, 2020-May 31, 2022) periods utilizing interrupted time series analysis. The secondary outcome reported scheduled surgery trends.

Results: 78,315 (10.6% inguinal hernia n = 8268; 89.4% gallbladder disease n = 70,064; n = 17 both inguinal hernia and gallbladder disease) patients were included. The post-cancellation period experienced a decreased trend change for inguinal hernia patients who received hospital admission (- 146.0%; p < 0.001), urgent interventions (- 171.0%; p < 0.001), and hernia repairs (- 164.0%; p < 0.001). For gallbladder disease patients, the post-cancellation period demonstrated a decreased trend in hospital admission (- 106.0%; p = 0.038) and an increased trend in day surgery transfers (- 1285.0%; p = 0.015) and median ED length of stay (82.0%; p = 0.0042). During the cancellation period, inguinal hernia and gallbladder disease surgeries decreased by 66.7% and 55.6%, respectively.

Conclusions: Despite a two-month surgery cancellation period, inguinal hernia and gallbladder disease patients demonstrated minimal differences in outcomes. During periods of ED boarding and crowding, scheduled surgery cancellations may be considered with minimal risk of potential adverse patient effects.
