目的全面了解辖区医疗机构消毒工作现状及工作质量,改进医疗单位消毒隔离工作中的薄弱环节,提高医护人员消毒与灭菌技术水平,防止医院感染的发生。方法采用现场调查与采样检测方法对辖区693家不同性质医疗机构消毒效果进行监测。结果 2011年宝安区各级医疗机构消毒效果监测合格率为96.45%,公立医疗机构合格率为98.02%,民营医院合格率为97.57%,社区健康服务中心的合格率为97.49%,个体诊所和门诊部的合格率为95.81%,对不同性质医疗机构的消毒效果监测合格率进行统计学检验,差异有统计学意义(χ2=24.291,P<0.01)。使用中消毒剂等6种样品的监测合格率大于95%,处理后污水、紫外线灯强度和室内空气的合格率低于95%。结论民营医院处理后污水和紫外线灯强度合格率低,可能成为医疗机构院内感染流行或暴发的潜在危险因素。个体诊所和私人门诊部消毒效果监测合格率低于大型医疗机构和社区健康服务中心,消毒隔离工作水平有待提高。 Objective To comprehensively understand the status quo and quality of disinfection work in medical institutions in the area, improve the weak links in disinfection and isolation of medical units, improve the technical level of disinfection and sterilization of medical staff, and prevent the occurrence of nosocomial infections. Methods The field investigation and sampling methods were used to monitor the disinfection effects of 693 medical institutions of different nature.

In the use of disinfectant and other six kinds of samples of the monitoring pass rate of more than 95%, after treatment of sewage, UV lamp intensity and indoor air pass rate of less than 95%. Conclusion The passing rate of wastewater and UV lamp after treatment in private hospitals is low, which may become a potential risk factor for the epidemic or outbreak of nosocomial infection in medical institutions. Disinfection monitoring of individual clinics and private clinics pass rate lower than large-scale medical institutions and community health service centers, disinfection and isolation work needs to be improved.
