Abstract

Background: Patient attendance at emergency departments (EDs) during the COVID-19 pandemic outbreak has decreased dramatically under the “stay at home” and “lockdown” restrictions. By contrast, a notable rise in severity of various surgical conditions was observed, suggesting that the restrictions coupled with fear from medical facilities might negatively impact non-COVID-19 diseases. This study aims to assess the incidence and outcome of complicated appendicitis (CA) cases during that period. Methods: A retrospective study comparing the rate and severity of acute appendicitis (AA) cases during the COVID-19 initial outbreak in Israel during March and April of 2020 (P20) to the corresponding period in 2019 (P19) was conducted. Patient data included demographics, pre-ED status, surgical data, and postoperative outcomes. Results: Overall, 123 patients were diagnosed with acute appendicitis, 60 patients during P20 were compared to 63 patients in P19. The rate of complicated appendicitis cases was significantly higher during the COVID-19 Lockdown with 43.3% (26 patients) vs. 20.6% (13 patients), respectively (p < 0.01). The average delay in ED presentation between P20 and P19 was 3.4 vs. 2 days (p = 0.03). The length of stay was 2.6 days in P20 vs. 2.3 days in P19 (p = 0.4), and the readmission rate was 12% (7 patients) vs. 4.8% (3 patients), p = 0.17, respectively. Logistic regression demonstrated that a delay in ED presentation was a significant risk factor for complicated appendicitis (OR 1.139, CI 1.011–1.284). Conclusion: The effect of the COVID-19 initial outbreak and Lockdown coupled with hesitation to come to medical facilities appears to have discouraged patients with acute appendicitis from presenting to the ED as complaints began, causing a delay in diagnosis and treatment, which might have led to a higher rate of complicated appendicitis cases and a heavier burden on health care systems.
