Abstract：Objective To explore the value and application effect of continuous quality improvement management mode in microbiological testing at Center for Disease Control and Prevention.Methods The period for sample selection was from January to December 2024,with a sample size of 200 test samples collected in Linqu County Center for Disease Control and Prevention.The samples were grouped according to time interval,among which 100 samples during the period of implementing conventional management mode from January to June 2024 were included in control group,and 100 samples during the period of implementing continuous quality improvement management mode from July to December 2024 were included in observation group.The scores of management quality(including management methods,management content and system compliance effectiveness),staff response to public health emergencies ability(including personal protective equipment use,emergency project item preparation,correct use of inspection standards and skill improvement),and inspection operation qualification rates(including sample collection qualification rate,hospital supplies surface microbiological compliance rate and staff hand hygiene inspection compliance rate)of two groups were compared.Results The scores of management methods,management content and system compliance effectiveness in observation group were significantly higher than those in control group(management methods score:9.23±0.30 vs.8.96±0.24;management content score:9.20±0.38 vs.8.87±0.21;system compliance effectiveness score:9.25±0.37 vs.8.91±0.22;all P<0.05).The scores of personal protective equipment use,preparation of emergency items,correct use of inspection standards and skill improvement in observation group were significantly higher than those in control group(personal protective equipment use score:9.22±0.32 vs.8.91±0.26;emergency item preparation score:9.23±0.30 vs.8.85±0.28;correct use of inspection standards score:9.25±0.31 vs.8.87±0.27;skill improvement score:9.24±0.33 vs.8.90±0.25;all P<0.05).The qualified rate of sample collection,compliance rate of surface microorganisms on hospital supplies and compliance rate of staff hand hygiene inspection in observation group were significantly higher than those in control group(qualified rate of sample collection:100.00%vs.96.00%;compliance rate of surface microorganisms on hospital supplies:99.00%vs.93.00%;compliance rate of staff hand hygiene inspection:99.00%vs.92.00%;all P<0.05].Conclusion Actively introducing the continuous quality improvement management mode into the microbiological testing of Center for Disease Control and Prevention could significantly improve management quality,staff's ability to respond to public health emergencies and qualified rate of testing operations.
