Abstract
BackgroundAcute appendicitis cases increased in severity following COVID-19–related restrictions in March, 2020. We investigated if similar changes occurred during Wave 2. MethodsAcute appendicitis patients during Wave 1 were grouped 8 weeks before (Group A) and after (Group B) stay-at-home restrictions were initiated on March 15, 2020. Cases in Wave 2 were grouped 8 weeks before (Group C) and after (Group D) November 6, 2020. Groups were compared to equivalent time frames in 2018/2019. ResultsGroup A versus B revealed 42.6% decrease (confidence interval: −59.4 to −25.7) in uncomplicated appendicitis and 21.1% increase (confidence interval: 4.8–37.3) in perforated appendicitis. Similar patterns were noted comparing Group C versus D without statistical significance. The changes seen in Wave 1 were significantly different than in 2018/2019. This trend continued in Wave 2. ConclusionSimilar to Wave 1, acute appendicitis cases increased in severity during wave 2 of COVID-19, but with less prominence.
