在医院感染管理中导入ＰＤＣＡ循环，建立健全医院感染管理网络，制订一系列制度和质控标准，更新设备并加强管理，随机抽样和定期监测制度化，总结评价与奖罚兑现相结合。导入ＰＤＣＡ，通过实践，确实体现其先进性，同时提高医护质量，减少了医院感染发病率。 The PDCA cycle was introduced into hospital infection management, a hospital infection management network was established, a series of systems and quality control standards were developed, equipment was updated, management was strengthened, random sampling and regular monitoring were institutionalized, and a summary evaluation was combined with reward and penalty redemption. The introduction of PDCA, through practice, truly reflects its advanced nature, while improving the quality of medical care, reducing the incidence of nosocomial infections.
