The impact of the coronavirus disease 2019 pandemic on changes in antimicrobial prophylaxis and development of genito‐urinary tract infections after urodynamic study: A retrospective comparative study of a single rehabilitation hospital in Japan

Aims To investigate the changes in the proportion of antimicrobial prophylaxis (AP) during the urodynamic study (UDS) and the frequency of posttest genito‐urinary tract infections (GUTI) before and after coronavirus disease 2019 (COVID‐19) pandemic, and evaluate this associations. Patients and Methods Patients who underwent UDS between 2015 and 2021 were targeted, and they were allocated to pre‐2020 as before the appearance of COVID‐19 and post‐2020 as after that, and propensity score matching was performed. The impact on AP was assessed by the administration rate, and that on the development of febrile GUTI after UDS was assessed for an equivalence by the GUTI‐free rate at 7 days after testing. Results After matching, 384 cases of 192 cases each were included. The frequency of AP was 58.3% in pre‐2020 and 77.1% in post‐2020, an increase of about 19%, and the rate increased significantly in post‐2020 (p
