Differences in strategies for prevention of COVID-19 transmission in hospitals: nationwide survey results from the Republic of Korea

Abstract

Background: Hospital infection control measures against coronavirus disease 2019 (COVID-19) are often based on expert discretion due to the lack of detailed guidelines.Aim: To survey the current strategies for preventing the transmission of COVID-19 in medical institutions.Methods: Thirteen key issues related to the prevention of COVID-19 transmission within medical institutions were selected via discussion among infectious diseases specialists, and related critical questions were obtained following a review of national-level guide-lines in government databases. Six hospitals had an open survey between 11th and 25th August 2020 to provide responses to these topics. An online questionnaire developed from these data was sent to infection control teams at 46 hospitals in South Korea between 31st January 2021 and 20th February 2021.Findings: All 46 hospitals responded to the survey. All operated screening clinics, but 89.1% (41/46) allowed symptomatic patients without COVID-19-associated symptoms to visit general outpatient clinics. Most hospitals (87.2%, 34/39) conducted polymer-ase chain reaction (PCR) tests for all hospitalized patients. Of 35/46 (76.1%) hospitals with pre-emptive isolation policies for hospitalized patients, 31 (88.6%) released patients from isolation after a single negative PCR test, while most (76.9%, 20/26) allowed shared-room accommodation for patients meeting the national criteria for release from isolation despite positive PCR results with above cycle threshold values (34.6%, 9/26), or after a certain period that satisfied the national criteria (26.9%, 7/26).Conclusion: Individual hospitals in South Korea are currently relying on experience to frame relevant guidelines, and responded differently to some infection control issues on hospital settings during the COVID-19 pandemic. 2022 The Healthcare Infection Society.
