某醫學中心內科病房 COVID-19 之異常事件經驗

2023年4月，在北部某醫學中心內科病房發生COVID-19異常事件，如何透過疫情調查、擴大篩檢及確診者安置等感染管制措施，使得疫情有效控制。COVID-19疫情前，院內明定有「健康監測通報規範機制」、「感染管制群突發及異常事件處理規範」、「疫災應變計畫啟動前因應措施分工」等相關院內政策，並依據疾病管制署公告之指引「醫院因應院內發生COVID-19確定病例之應變處置建議」，機動調整及因應。最終發現15位確診者，分析此次事件發現無症狀之陽性個案占66.7%，無症狀感染者在被診斷出來前，就具有傳染力，是在COVID-19疫情社區常態化後感染管制的重要課題，在異常事件中，透過篩檢監測，以及時鑑別出無症狀確診者，採取積極隔離措施，遏止蔓延及擴散，是以防堵病毒散播的重要策略。

In April 2023, a COVID-19 cluster event occurred in the internal medicine ward of a medical center in the northern region. The effective control of the outbreak involved implementing infection control measures such as epidemiological investigation, expanding screening, and arranging for the isolation of confirmed cases. Prior to the COVID-19 pandemic, the hospital had established relevant infection control policies, including“the Health Monitoring Notification Mechanism,”“Infection Control Abnormal Event Handling Regulations,”and“Prepared Measures Division in Response to Activation of the Epidemic Contingency Plan.”The hospital dynamically adjusted and responded based on the guidelines provided by the Centers for Disease Control and Prevention (CDC) , Taiwan in their announcement titled“Guidelines for Hospitals Responding to Confirmed COVID-19 Cases Within the Hospital.”Ultimately, 15 confirmed cases were identified, with the analysis revealing that asymptomatic individuals accounted for 66.7% of the positive cases. In the context of the cluster event, timely screening and monitoring were crucial for identifying asymptomatic confirmed cases. Implementing proactive isolation measures served as an important strategy to curb the spread and prevent further dissemination.
