Abstract

In this paper, we propose impact factors and validity of blood variables on death of COVID-19 patients. The clinical-epidemiological data of 5628 COVID-19 patients, provided from Korea Disease Control and Prevention Agency as day of 30th April 2020, were used. As results, impact factors of death were dementia, older age, high lymphocyte, cancer, dyspnea, COPD, change of consciousness, heart disease, high platelets, abnormal diastolic pressure and fever. The validities of blood variables for death were high in the order of lymphocyte, hemoglobin, hematocrit, platelet and WBC. Therefore, risk factors such as initial clinical characteristics, underlying disease and blood test results, could be regarded for efficient management of COVID-19 patients.

본 연구에서 우리는 COVID-19의 사망에 대한 영향요인과 혈액변수의 타당도를 제안하였다. 이 연구를 위하여 질병관리본부 중앙방역대책본부에서 제공하는 2020년 4월 30일까지 격리해제되었거나 사망한 COVID-19확진자 5628명의 임상역학정보를 활용하였으며, 자료는 R 3.4.1을 사용하여 분석하였다. 분석결과, 사망에 대한 위험요인으로 치매(HR 7.03), 많은 나이(HR 5.39), 높은 림프구(HR 4.66), 암(HR 4.27), 호흡곤란(HR 3.25), 만성폐쇄성 폐질환(HR 3.22), 의식변화(HR 3.13), 심장질환(HR 2.24), 높은 혈소판(HR 2.14), 비정상 이완기 혈압(HR 2.02), 열(HR 1.69)이 확인되었다. 사망에 대한 혈액검사의 타당도는 림프구, 헤모글로빈, 헤마토크리트, 혈소판, 백혈구 순으로 정확도가 높았다. 그러므로 COVID-19 환자를 치료할 때 사망의 위험요인으로 확인된 초기 임상적 특징 및 기저질환, 혈액검사의 소견을 고려하여 보다 효율적인 관리가 가능하도록 해야 할 것이다.
