Application of PDCA circle management model in hospital environmental hygiene monitoring

OBJECTIVE To investigate the effect of application of Plan-Do-Check-Act（PDCA） circle management model on hospital environmental hygiene monitoring. METHODS Chi-square test or Fisher exact test was used to analyze and compare the dynamic changes of environmental health monitoring data from 2018 to 2020 after the introduction of PDCA cycle management model, and the environmental health monitoring data in 2017 was as the reference. RESULTS The qualified rates of overall environmental hygiene monitoring, object surface, dialysate and dialysis water increased year by year, from 95.7%, 91.0%, 94.5% and 82.0% in 2017 to 97.5%, 97.0%, 100.0% and 98.6% in 2020, respectively. The accuracy rate of hand hygiene increased year by year, rising from 88.48% in 2017 to 93.06% in 2020. The differences in the qualified rates of overall environmental hygiene monitoring, object surface and dialysate between 2020 and 2017 were significantly different（P＜0.05）. The qualified rates of dialysis water from 2018 to 2020 was significantly different from that in 2017（P＜0.05）. The correct rates of hand hygiene in 2019 and 2020 was significantly different from that in 2017（P＜0.05）, while the qualified rate of hand disinfection was not significant, although reaching the planned target（＞85%）. The qualified rate of dialysis water had reached the planned target since 2018（＞90%）. CONCLUSION The introduction of PDCA circle management model can effectively enhance the management quality of hospital environmental hygiene monitoring, thereby improving medical safety.
