Objective To establish and promote a COVID-19 screening process based on an information integrated system. Methods: 4578 patients with fever and patients with epidemic history who visited the fever clinic of our hospital from January 2020 to June 2021 were selected for SCREENING for COVID-19 to evaluate the practical value of this procedure in screening. Results: As time varied, all the participants successfully completed blood routine, influenza A, chest CT scan and throat swab nucleic acid test according to the requirements of COVID-19 diagnosis and treatment protocol (trial version 1 to 6). CT images meet the clinical diagnostic criteria. In terms of the time of visit, in the early period (January-February 2020), there were 1156 patients in the general procedure group; In the later period (March 2020 -- June 2021), a total of 3,422 people will use the COVID-19 screening process based on the information integration system (hereinafter referred to as the Information integration process Group).With the use of the information integration process, the average time for each patient from entering the fever clinic to leaving the clinic was reduced from 3.6-4.8 hours to 1.5-1.8 hours on average. The average investigation time was reduced from 2.5-2.9 hours to 0.6-0.8 hours. The average doctor-patient contact time decreased from 2.1-2.4 hours to 0.35-0.42 hours. No doctor-patient infection occurred. The diagnostic accuracy was 100%. Because patients stay in fever clinic for a long time, it is easy to cause emotional fluctuation, excitement, and even aggressive behavior of patients. 254 patients (21.97%) had emotional fluctuation and excitement in the early stage. In the later stage, there were 240 cases of mood fluctuation and agitation, accounting for 7.01%. 104 patients (8.99%) had aggressive behavior from the early stage; There were 119 patients with aggressive behavior in the later stage, accounting for 3.47%. It can significantly reduce the patients visit time, reduce the doctor-patient contact time, reduce the risk of doctor-patient infection, and reduce the emotional irritation to patients. Comparing the data of the two groups, P<0.05 shows a statistically significant difference, which fully indicates that the information integration process group is significantly better than the general process group. Conclusion The COVID-19 screening process based on the information integrated system can be used to quickly and accurately detect COVID-19. It is expected that this study will provide guidance and application value for other new infectious diseases that may appear in the future, as well as good use and promotion value.
