杭州市67家医疗机构口腔印模消毒质量调查

Investigation on the disinfection quality of dental impression in 67 medical institutions in Hangzhou

目的了解杭州市各级各类口腔科印模消毒质量现状,为提高本地区口腔印模消毒质量提供科学的基础数据。方法于2017年3-9月,对杭州地区36家综合医院口腔科、16家口腔专科医院和15家门诊部(含口腔诊所)的口腔印模的细菌污染情况进行调查。结果 58家开展口腔印模消毒的医疗机构,共采集微生物样本458份,合格224份,合格率48.91%;其中综合医院、专科医院和门诊部(含口腔诊所)的口腔印模消毒质量合格率分别为52.51%(136/259)、62.40%(78/125)、40.54%(30/74),差异有统计学意义(P=0.011);口腔专科医院的合格率最高,门诊部最低(P=0.003)。另有9家医疗机构未对口腔印模进行消毒处理,采集样本56份,合格率0。采用浸泡消毒方式处理的口腔印模的合格率为73.97%(108/146)高于喷雾消毒方式43.59%(136/312)(P<0.001)。结论杭州市医疗机构口腔印模细菌污染情况较严重,不同等级医疗机构的口腔印模消毒质量存在差异,需加强口腔印模的消毒知识培训与监测工作。
