COVID-19 Patients with Mild Symptoms or without Symptom Using Residential Treatment Center Model

Abstract

Background: The rapid rise in coronavirus disease worldwide has drastically limited the availability of hospital fa-cilities for patients. Residential treatment centers were opened in South Korea for the admission of asymptomatic or patients with mild symptoms. This study discusses the appropriateness of the admission criteria set by the cen-ters in a pandemic situation, the prioritization of patients for admission, and ways to minimize the risk of self -isola-tion. Methods: A total of 217 low-risk patients (n=217) were admitted to the Nowon Residential Treatment Center be-tween August 22 and October 14, 2020. The following criteria were met at the time of admission: patients (1) were asymptomatic or had mild symptoms, (2) had either a controlled or no underlying chronic disease, and (3) did not need oxygen treatment. Among them, 202 patients who were eligible for inclusion in the study were retrospectively investigated through periodic interviews. Results: Of the 202 patients, 153 satisfied the criteria for symptomatic isolation standards, and 25 for asymptomatic isolation standards. The clinical conditions of 24 patients were aggravated, and these patients were transferred to other hospitals, among which 12 had persistent fever and 13 were suffering dyspnea with oxygen saturation (SpO(2)) <95%. Conclusion: In the event of another large-scale epidemic, it would be appropriate to prioritize accommodating pa-tients who are elderly or have underlying diseases and self-isolate young patients with no underlying diseases and provide them with SpO(2) meters and thermometers to self-measure SpO(2) and body temperature.
