ABSTRACT
Objectives: COVID-19 began spreading widely in China in January 2020. Outpatient Fever Clinics (FCs), instituted during the SARS epidemic in 2003 were upgraded to provide COVID-19 screening and prevention attached to large tertiary hospitals. We sought to analyze the effect of upgraded FCs to detecting COVID-19 at our institution. Design: A population-based cross-sectional study. Participants: A total of 6,365 patients were screened in the FC. Methods: The FC of Peking Union Medical College Hospital (PUMCH) was upgraded on January 20, 2020. We performed a retrospective study of patients presenting to the FC between December 12, 2019 to February 29, 2020, covering a period of 40 days before and after upgrading the FC. All necessary data, including baseline patient information, diagnoses, follow-up conditions for critical patients, transfer information between the FC and emergency department (ED) were collected and analyzed. Results: 6,365 patients were screened in the FC, among whom 2,192 patients were screened before January 21, 2020, while 3,453 were screened afterwards. Screening results showed that upper respiratory infection was the major disease associated with fever. Compared to before the outbreak, patients transferred from the FC to ED decreased significantly [39.21% vs 15.75%, p<0.001] and tended to spend more time in the FC [55 vs 203mins, p<0.001]. For critically-ill patients waiting for a screening result, the total length of stay in the FC was 22mins before the outbreak, compared to 442mins after the outbreak (p< 0.001). The number of in-hospital deaths of critical-care patients seen first in the FC was 9 of 29 patients before the outbreak and 21 of 38 after (p<0.050). Nineteen COVID-19 cases were confirmed in the FC, but no other patients or medical care providers were cross-infected. Conclusion: The work-load of the FC increased after the COVID-19 outbreak and effectively prevented COVID-19 from spreading in the hospital as well as offload ED resources.

Objective@#To study the clinical characteristics of 2019 coronavirus (2019-nCoV) pneumonia patients and make a feasible screening process in fever clinic.@*Methods@#Epidemiologic features, clinical presentation, laboratory findings and image features of the screened patients were retrospectively collected and analyzed.@*Results@#Totally, 46 patients were screened, 9 of them were laboratory-confirmed 2019-nCoV infection, and others were defined as laboratory-excluded patients. Laboratory-confirmed patients had higher frequency of travelling or residence in Wuhan within two weeks of onset (P<0.05), but there were no differences on age, sex, other epidemiologic features and comorbidities between the two groups (P>0.05). The most common feature of the laboratory-confirmed patients was fever (100%), but the symptoms showed no differences between the two groups (P>0.05). Laboratory-confirmed patients had lower white blood cell count than the laboratory-excluded patients (P<0.05), and all of them had pneumonia in chest CT scan. None of the patients with normal chest CT had positive 2019-nCoV nucleic acid test.@*Conclusions@#No specific symptom was helpful in the diagnosis of 2019-nCoV infection. However, patients without chest CT scan changes had a very low risk of 2019-nCoV infection despite of the epidemiologic history and fever. We recommended a screening procedure that might be helpful to reduce the rate of miss diagnosis and improve screening efficiency.
