Objective To explore the role of WeChat platform combined with flipped classroom in improving the working ability of resident doctors in the fever clinic. Methods　A total of 118 resident doctors who rotated in the fever clinic of department of emergency medicine were selected as the study subjects

and they were randomized into experimental group and control group

with 59 people in each group. The experimental group used WeChat platform and flipped classroom teaching

and the control group used traditional teaching. The results of theory assessment

operation performance and questionnaire survey were compared between the two groups. SPSS 26.0 statistical software was used for t test and chi-square test. Results　There was no significant difference in theoretical test scores between the experimental group and the control group (P>0.05). The experimental group scored (91.61±3.01) points and the control group scored (84.52±4.02) points in operational assessment

with significant differences (t=-10.85

P<0.05). The results of the satisfaction survey showed that there was no significant difference in teaching time distribution between the two groups

and the experimental group was better than the control group in any other aspects. Conclusion　The use of WeChat platform combined with flipped classroom during the COVID-19 epidemic can improve the level of operational skills of the resident doctors to wear or take off the protective clothing and collect nasopharyngeal swabs

help residents to avoid the infections

and improve the level of daily diagnosis and treatment of fever clinic.
