微生物检验在医院感染管理中的效果研究

Study on the Effectiveness of Microbiological Testing in Hospital Infection Management

摘要: 目的：研究微生物检验在医院感染管理中的效果。方法：选取本院2022年四个季度至2023年四个季度环境卫生学监测样本作为研究对象。以2022年四个季度实施常规环境卫生学监测为对照组(n = 550)，2023年四个季度实施基于微生物检验的精细化环境卫生学监测为研究组(n = 580)，分析干预效果。结果：研究组相关项目监测合格率显著高于对照组(P < 0.05)；研究组医务人员的手卫生依从性和正确率均显著高于对照组(P < 0.05)；研究组医院感染发病率、漏报率及感染患者平均住院日均显著低于对照组(P < 0.05)。结论：在医院感染管理中应用微生物检验可显著提高环境卫生学监测合格率，提升医务人员手卫生依从性与操作规范性，有效降低医院感染发病率、漏报率及感染患者平均住院日，对优化医院感染管理质量、保障医疗安全具有重要的实践意义。

Abstract: Objective: To investigate the effectiveness of microbiological testing in hospital infection management. Methods: Environmental hygiene monitoring samples from the first four quarters of 2022 to the first four quarters of 2023 were selected as the study subjects. The routine environmental hygiene monitoring conducted in the first four quarters of 2022 served as the control group (n = 550), while the refined environmental hygiene monitoring based on microbiological testing conducted in the first four quarters of 2023 served as the study group (n = 580). The intervention effects were analyzed. Results: The compliance rate of relevant items in the study group was significantly higher than that in the control group (P < 0.05). The compliance and accuracy of hand hygiene practices among medical staff in the study group were significantly higher than those in the control group (P < 0.05). The incidence of hospital-acquired infections, underreporting rate, and average length of stay for infected patients in the study group were significantly lower than those in the control group (P < 0.05). Conclusion: The application of microbiological testing in hospital infection management can significantly improve the compliance rate of environmental hygiene monitoring, enhance the compliance and standardization of hand hygiene practices among medical staff, and effectively reduce the incidence of hospital-acquired infections, underreporting rates, and the average length of stay for infected patients. This has important practical significance for optimizing the quality of hospital infection management and ensuring medical safety.
