目的探讨提高医疗机构消毒效果的方法,为医院感染管理体系的完善提供科学依据。方法制定对部分市级和县级医疗机构的干预措施,采样检测消毒效果关键指标,并对干预前后的采样监测结果进行统计评价。结果医院消毒管理干预前后消毒灭菌效果差异有统计学意义(χ2=16.447,P<0.01);干预后,市县两级医疗机构重点部门环境空气采样合格率均有明显提高,空气总体合格率由干预前的76.79%提高到干预后的95.87%,空气监测结果差异有统计学意义(χ2=20.741,P<0.01);物体表面(χ2=0.034,P=0.854)、医疗器械(χ2=0.132,P=0.716)、医务人员手监测结果差异无统计学意义。结论所采取的干预措施能够显著提高医疗机构消毒效果。
Objective To explore ways to improve the disinfection effect of medical institutions and provide a scientific basis for the improvement of hospital infection management system. Methods Develop interventions for some municipal and county-level medical institutions, sample and test the key indicators of disinfection effect, and make statistical evaluation on sampling and monitoring results before and after intervention. Results There were significant differences in disinfection and sterilization before and after hospital disinfection management (χ2 = 16.447, P <0.01). After the intervention, the qualified rate of ambient air sampling in key departments of city and county hospitals increased significantly, and the overall pass rate of air (Χ2 = 0.034, P = 0.854), medical device (χ2 = 0.132, P <0.01), and the difference between the two groups was statistically significant (χ2 = 20.741, , P = 0.716). There was no significant difference in the results of medical staff monitoring. Conclusion The interventions can significantly improve the disinfection effect of medical institutions.
