2005-2007年广东省医疗机构消毒质量监测分析

Surveillance of quality of disinfection in hospitals in Guangdong province,2005-2007

目的了解广东省各级医疗机构消毒监测质量,探讨消毒监测中存在的问题,加强医院感染监控力度。方法收集2005-2007年广东省疾病预防控制机构按照统一的技术方案对医疗机构进行消毒质量监测的数据,并用SPSS统计软件进行分析。通过对不同监测项目的监测结果进行分析,发现医疗机构消毒质量存在的问题。结果2005-2007年全省医疗机构消毒监测样品总数依次为142 969、140 014、161 991份,合格率依次为91.10%、90.71%、91.22%,总合格率为91.02%。3年的合格率比较差异无统计学意义(χ2=1.644,P>0.05)。3年间市、县、镇三级医疗机构的消毒质量监测合格率依次为93.59%、93.94%、89.34%,有统计学意义,呈市、县级别的合格率均比镇级高的趋势。监测项目中,以使用中消毒液的合格率97.62%为最高,其次为压力蒸汽灭菌效果95.98%和灭菌医疗用品95.63%。医务人员手合格率为90.67%,空气中细菌含量的合格率最低,仅为73.25%。经比较各类监测项目的合格率差异有统计学意义(χ2=36768.34,P<0.05)。结论在不同级别的医疗机构消毒监测侧重点应有所不同,镇以下医疗机构是今后消毒监测工作的重点。

Objective To evaluate the quality of disinfection in hospitals in Guangdong province, find out the problems in disinfection surveillance and strengthen the surveillance of nosocomial infections. Methods Since the surveillances on the quality of disinfection in hospitals were conducted by the centers for diseases control and prevention in Guangdong Province according to the same guidelines from 2005 to 2007, the surveillance data were collected and analyzed by SPSS software. Results From 2005-2007, 142 969, 140 014 and 161 991 samples for surveillance were detected with the qualified rate of 91.10%, 90.71% and 91.22% respectively, the overall qualified rate was 91.02%. The differences on qualified rates in 3 years had no statistical significance by χ2 test （χ2 = 1. 644, P 〉 0.05 ）. The qualified rates of hospitals at municipal, county and township level in 3 years were 93.59% , 93.94% and 89.34% respectively, which had statistical significance by χ2 test. The qualified rates in all municipal and county hospital were higher than in township health centers. Among the surveillance items, the qualified rate of disinfectant was the highest （97.62%）, followed by pressure steam sterilizing （95.98%） and sterilizing medical instruments （95.63%）. The qualified rate for the hand disinfection of medical staff was 90.67 %. The qualified rate of the bacterial contents in air was the lowest （73.25 % ） The difference on the qualified rate of different items had statistical significance. Conclusion The disinfection surveillance in hospitals at different level should be differed on the field to be monitored, and the disinfection surveillance for medical agencies at township level is the priority in furore.
