The aim of this study was to examine the impact of enhanced in-hospital infection prevention during the COVID-19 pandemic on postoperative pneumonia in older surgical patients. A retrospective review of electronic medical records was conducted for patients aged ≥70 who underwent elective surgery between 2017 and 2021. The study found that although there was a decreasing trend in the monthly incidence rate of postoperative pneumonia during the COVID-19 pandemic, the difference was not statistically significant.
Purpose: We aimed to investigate the impact of enhanced in-hospital infection prevention during the coronavirus disease 2019 (COVID-19) pandemic on postoperative pneumonia in older surgical patients.Patients and Methods: We retrospectively reviewed the electronic medical records of consecutive patients >= 70 years who under-went elective surgery between 2017 and 2021 at our institution. All perioperative variables were retrieved from the electronic medical records. The primary outcome was new-onset postoperative pneumonia during the hospitalization period. Since February 2020, our institution implemented a series of policies to enhance infection prevention, hence patients were divided into groups according to whether they underwent surgery before or during the COVID-19 pandemic. An interrupted time series analysis was performed to evaluate the difference between pre-and post-intervention slopes of the primary outcome.Results: Among the 29,387 patients included in the study, 10,547 patients underwent surgery during the COVID-19 pandemic. Although there was a decreasing trend of the monthly incidence rate of postoperative pneumonia compared to before the COVID-19 pandemic, there was no statistical significance in the trend (slope before COVID-19 period: beta-coefficient, -0.007; 95% CI, -0.022 to 0.007).Conclusion: Our study revealed that enhanced in-hospital infection prevention implemented to manage the COVID-19 pandemic did not significantly affect the decreasing trend of postoperative pneumonia at our institution.
