Abstract

Introduction

Coronavirus disease 2019 (COVID-19) has greatly impacted medical care practices. Although the effects on infectious disease treatment and infection control, such as antimicrobial resistance, have been specified, very few reports exist on the specific effects of COVID-19.

Methods

We investigated the effects of COVID-19 on daily medical practices at a tertiary hospital in Japan by comparing the use of hand sanitizers, the detection of bacteria from blood cultures, and the amount dose of antibacterial drugs used for one year before (April 2019 to March 2020, fiscal year 2019.) and after COVID-19 admissions began (April 2020 to March 2021, fiscal year 2020).

Results

The use of hand sanitizers increased by 1.4–3 times during the year after COVID-19 admissions began; the incidence of methicillin-susceptible Staphylococcus aureus and all S. aureus detected in blood cultures reduced in all departments. No decrease was observed in the usage of all antibacterial drugs; rather, the usage of all antibacterial drugs tended to increase in all departments. Therefore, no significant change was observed in the detection of drug-resistant bacteria and the trends of antibacterial drug use based on the acceptance of COVID-19 patients.

Conclusions

The prevalence of drug-resistant bacteria and trends of antibacterial drug use remained unchanged despite the increased use of hand sanitizers due to the admission of patients with COVID-19.
