The ongoing global SARS-CoV-2 pandemic has caused over 4.7 million infections greatly challenging healthcare workers (HCW) and medical institutions worldwide. The SARS-CoV-2 pandemic has shown to significantly impact mental and physical health of HCW. Thus, implementation of testing facilities supporting HCW are urgently needed.
A low-threshold SARS-CoV-2 testing facility was introduced at the University Hospital Bonn, Germany, in March 2020. Irrespective of clinical symptoms employees were offered a voluntary and free SARS-CoV-2 test. Furthermore, employees returning from SARS-CoV-2 risk regions and employees after risk contact with SARS-CoV-2 infected patients or employees were tested for SARS-CoV-2 infection. Pharyngeal swabs were taken and reverse transcription polymerase chain reaction for detection of SARS-CoV-2 was performed, test results being available within 24 h. Profession, symptoms and reason for SARS-CoV-2 testing of employees were recorded.
Between 9th March and April 30, 2020, a total of 1510 employees were tested for SARS-CoV-2 infection. 1185 employees took advantage of the low-threshold testing facility. One percent (n = 11) were tested positive for SARS-CoV-2 infection, 18% being asymptomatic, 36% showing mild and 36% moderate/severe symptoms (missing 10%). Furthermore, of 56 employees returning from SARS-CoV-2 risk regions, 18% (10/56) were tested SARS-CoV-2 positive. After risk contact tracking by the hospital hygiene 6 patient-to-employee transmissions were identified in 163 employees with contact to 55 SARS-CoV-2 positive patients.
In the absence of easily accessible public SARS-CoV-2 testing facilities low-threshold SARS-CoV-2 testing facilities in hospitals with rapid testing resources help to identify SARS-CoV-2 infected employees with absent or mild symptoms, thus stopping the spread of infection in vulnerable hospital environments. High levels of professional infection prevention training and implementation of specialized wards as well as a perfectly working hospital hygiene network identifying and tracking risk contacts are of great importance in a pandemic setting.
持续的全球 SARS-CoV-2 大流行导致超过 470 万人感染，这给全球医护人员（HCW）和医疗机构带来了巨大挑战。SARS-CoV-2 大流行已明显影响 HCW 的身心健康。因此，迫切需要建立支持 HCW 的检测设施。
2020 年 3 月，德国波恩大学医院引入了一个低门槛 SARS-CoV-2 检测设施。无论临床症状如何，员工都可自愿且免费接受 SARS-CoV-2 检测。此外，从 SARS-CoV-2 风险地区返回的员工和与 SARS-CoV-2 感染患者有风险接触或接触 SARS-CoV-2 感染患者的员工也要接受 SARS-CoV-2 感染检测。采集咽拭子并进行逆转录聚合酶链反应检测 SARS-CoV-2，检测结果在 24 小时内获得。记录员工的职业、症状和 SARS-CoV-2 检测原因。
2020 年 3 月 9 日至 4 月 30 日，共有 1510 名员工接受了 SARS-CoV-2 感染检测。1185 名员工利用低门槛检测设施进行检测。检测呈阳性的有 1%（n=11），无症状的占 18%，轻症的占 36%，中重度/严重症状的占 36%（缺失 10%）。此外，56 名从 SARS-CoV-2 风险地区返回的员工中，18%（10/56）检测呈 SARS-CoV-2 阳性。医院卫生部门对风险接触者进行追踪后，在与 55 名 SARS-CoV-2 阳性患者有接触的 163 名员工中发现了 6 例患者向员工的传播。
在缺乏便捷的公共 SARS-CoV-2 检测设施的情况下，医院内设有低门槛 SARS-CoV-2 检测设施且具备快速检测资源，有助于发现无症状或轻症的 SARS-CoV-2 感染员工，从而阻止感染在脆弱的医院环境中传播。在大流行期间，高度重视专业感染预防培训以及专门病房的实施，以及一个完善运作的医院卫生网络，识别和跟踪风险接触者，这一点非常重要。
