Abstract:

Objective To formulate a three-level screening process for COVID-19 to cut off the virus transmission route as early as possible and reduce the exposure to virus sources. Methods The first-level screening consisted of two steps triage：fast triage station in each entrance of medical areas and fever clinic triage station with forward checklist screening to find out suspected patients as early as possible. The secondary screening was performed for patients in a completely closed management manner，to further confirm the epidemiological history and Symptom，and then combine with blood routine，chest radiograph or CT imaging results to confirm suspected cases. The tertiary screening focused on the management of suspected cases. The patients with COVID-19 were accurately screened through two nucleic acid tests. Results Until 8:00 AM of 9th February，1589 suspected patients were screened in the triage stations of fever clinic which was first-level screening. 282 cases were screened in fever clinic which was secondary screening，39 suspected patients were screened in isolated observation area which was tertiary screening. In the end，3 cases were confirmed and transported to the designed hospital for isolation treatment. No nurses and doctors were infected and no patients were missed. Conclusion The three-level screening process is clear and strictly prevents missed diagnosis，and effectively reduces the risk of transmission within medical  institutions.
