醫學中心介入並成功阻斷某長照機構嚴重特殊傳染性肺炎群聚感染處理

Effective Control of the COVID-19 Outbreak in a Long-Term Care Facility: A Medical Centers Experience

從2019年底新冠肺炎疫情開始至今，造成全球人類大量感染甚至導致死亡。2021年5月首波疫情嚴重肆虐台灣本土，政府實施滾動式防疫政策，醫學中心調整設施及醫療人力，紓解大量的確診個案，除照護醫院的就醫個案外，也具有維護社區醫療的責任。某長照機構內部發生嚴重群聚感染，此疫情發生在快篩試劑尚未普及時，醫院於長照機構首位指標個案確診後第9日派員協助擴大篩檢，使用病毒核酸檢驗方式，協助將接觸者篩檢，並協助機構分艙分流。首波接觸者篩檢結果呈現33.8%(25/74)陽性率，透過轉院模式盡速將確診住民轉入醫院隔離治療;無症狀和輕症確診看護及工作人員安置到防疫旅館及檢疫所。此群聚事件醫院團隊介入之後感染率從42.2%(35/83)降至26.0%(20/77)，終止於第15日，總感染率為49.1%(55/112)。機構清空後進行消毒及靜置，於清空靜置14天後工作人員歸建及住民入住。

Since 2019, COVID-19 has led to numerous cases and deaths globally. The Taiwan Centers for Disease Control (CDC) have continuously updated their epidemic prevention strategies in response to the unpredictable situation. Breakthrough infections have been observed in various COVID-19 clusters, particularly in long-term care (LTC) facilities. The infection control team at a medical center took charge of managing and preventing the disease. They conducted mass COVID-19 testing at the LTC facility using polymerase chain reaction (PCR) in a certified lab. The analysis showed that around 33.8% (25 over 74) of individuals at the LTC facility tested positive for COVID-19. All cases within the LTC were classified as either infected or non-infected. Infected cases with severe symptoms were promptly isolated and sent to hospitals for treatment, while those with mild symptoms were quarantined. The infection rate decreased from 42.2% (35 out of 83) to 26.0% (20 out of 77) during this cluster outbreak. The strategy employed focused on stopping transmission and implementing prevention measures after conducting screenings. To prevent the spread of the SARS-CoV-2 virus, all staff and residents at the facility were required to evacuate and could only return after a thorough cleaning and disinfection process.
