Background: The novel coronavirus (COVID-19) strain has resulted in restrictions potentially impacting patients presenting with acute appendicitis and their disease burden. Methods: All acute appendicitis admissions (281 patients) between 1/1/2018-4/30/2020 were reviewed. Two groups were created: 6 weeks before (Group A) and 6 weeks after (Group B) the date elective surgeries were postponed in Massachusetts for COVID-19. Acute appendicitis incidence and disease characteristics were compared between the groups. Similar time periods from 2018 to 2019 were also compared. Results: Fifty-four appendicitis patients were categorized in Group A and thirty-seven in Group B. Those who underwent surgery were compared and revealed a 45.5% decrease (CI: 64.2,-26.7) in uncomplicated appendicitis, a 21.1% increase (CI:3.9,38.3) in perforated appendicitis and a 29% increase (CI:11.5,46.5) in gangrenous appendicitis. Significant differences in the incidence of uncomplicated and complicated appendicitis were also noted when comparing 2020 to previous years. Conclusions: The significant increase in complicated appendicitis and simultaneous significant decrease in uncomplicated appendicitis during the COVID-19 pandemic indicate that patients are not seeking appropriate, timely surgical care.
