Infection and mortality rates caused by the coronavirus infectious disease 2019 (COVID-19) pandemic were high. However, the influence of the COVID-19 pandemic on the clinical burden in medical facilities remains to be clarified in Japan.

This study used a questionnaire-based web survey to clarify how the COVID-19 pandemic affected infectious disease practice and infection control. The questionnaire was sent to healthcare professionals at nationwide medical facilities between January 13, 2023, and February 15, 2023.

Responses were obtained from 1784 healthcare professionals throughout Japan. Hospital management of COVID-19 patients was the responsibility of 96.5% of respondents. Furthermore, 75.1% had experienced nosocomial spread of COVID-19. Manuals and infection control measures for COVID-19 have been arranged in most facilities. In many facilities, the timing of an infected employee's return to work was determined in accordance with the isolation period for coronavirus-positive patients with symptoms established by the Ministry of Health, Labor and Welfare in Japan. Approximately 30% of respondents reported that caring for COVID-19 patients, including the use of personal protective equipment, was their most stressful job. Approximately 50% of the respondents reported an increase in overtime hours. Approximately 90% of facilities are now capable of performing COVID-19 testing onsite.

Infection control for COVID-19 has been improved, and testing equipment for SARS-CoV-2 has been prepared. Patient care-related burdens and burdens caused by having to compensate for vacancies due to infected staff members have increased. In the future, a reduction in workload and role sharing should be considered.
