摘　　要：目的了解医院直饮水系统成品水和用户端细菌污染情况。方法按随机抽样的方法,对某院2011年1月—2012年2月医院直饮水的成品水、用户端直饮水和直饮机出水口内表面进行采样和细菌学培养。结果该院直饮水系统成品水的合格率为93.33%(28/30),用户端直饮水合格率为89.80%(88/98),直饮机出水口内表面细菌培养合格率为91.11%(41/45)。通过制定相应管理制度,规范机房及管路系统操作、保养、清洗、消毒流程等,上述指标分别提高至100.00%(90/90)、98.91%(182/184)、100.00%(150/150)(均P<0.05)。结论医院直饮水系统成品水和用户端存在细菌污染,加强直饮水输送管路及用户端规范化消毒管理,能提高直饮水的合格率。ObjectiveTo explore bacterial contamination of direct drinking water system in a hospital.MethodsFrom January 2011 to February 2012, random sampling of finished water, drinking water on clientserver and inner surface of outlet of drinking water machine in a hospital were taken and performed bacterial culture.ResultsThrough the formulation of management system and standardization of operation, maintenance, cleaning and disinfection process of drinking water system, the qualified rate of finished water, drinking water on clientserver,and bacterial culture of inner surface of outlet increased from 93.33% （28/30）to 100.00%（90/90）, 89.80%（88/98） to 98.91%（182/184）, and 91.11%（41/45） to 100.00% （150/150）respectively （all P〈0.05）.ConclusionBacterial contamination existed in finished water and drinking water on clientserver, strengthening the standardized disinfection management of drinking water pipes and the clientservers can effectively improve the qualified rate of direct drinking water.
