Objectives
Numerous studies have explored the causes and spread of outbreaks, yet there is a lack of research on post-coronavirus disease 2019 condition (PCC) in Korea. The goal of this study was to identify the various types of PCC and associated factors in discharged patients and to provide directions for the ongoing health management of confirmed patients.
Methods
A telephone survey was conducted among 680 coronavirus disease 2019 (COVID-19) patients diagnosed between July 7, 2021 and August 26, 2021, in Dangjin, Chungnam, Korea. A descriptive analysis of characteristics, univariate analysis, and regression were performed using data from basic epidemiological surveys conducted at the time of diagnosis and post-discharge questionnaires.
Results
Of the 585 patients who responded, 159 (27.2%) developed PCC. Of the 211 patients with no initial symptoms, 27 (12.8%) developed PCC, versus 132 (35.3%) of the 374 patients with initial symptoms. Among the initial symptoms, fever or chills, cough or sputum, loss of smell, and sore throat were associated with PCC. Compared to patients with less than 10 days of hospitalization, those with a hospitalization period of 21 days to 30 days (odds ratio [OR], 2.3; 95% confidence interval [CI], 1.0 to 5.2) and 31 days or more (OR, 5.8; 95% CI, 1.9 to 18.1) had a higher risk of PCC.
Conclusions
More than a quarter of COVID-19 patients, including those who had no initial symptoms, experienced PCC in Korea. People with the initial symptoms of fever, chills, and respiratory symptoms and those who had prolonged hospital stays had a high risk of PCC.
Summary
Korean summary
코로나19 후유증은 진단 시 초기증상과 연관되며, 입원기간이 길어질수록 후유증 발병 위험이 높았다. 코로나19 후유증의 위험인자에 대한 추가적인 연구가 필요하며, 이러한 특징을 갖는 확진환자를 대상으로 퇴원 후 지속직인 환자관리가 필요하다.
Key Message
Post-coronavirus disease 2019 condition (PCC) are associated with initial symptoms at diagnosis, and the risk of this increases with longer hospital stays. Further research on the risk factors for PCC is needed, and continued patient care is necessary for confirmed patients with these characteristics after discharge.
