5种不同类型水龙头洗手时平均耗水量比较

Average consumption of water running through five different types of faucets

摘要:

目的调查临床中使用的5种不同类型水龙头（脚碰式、脚踏式、肘碰式、感应式、手触式）洗手时的耗水量，为临床合理使用水龙头提供依据。方法随机抽取100名临床各科室医务人员，分成5组（20人/组），分别使用脚碰式、脚踏式、肘碰式、感应式、手触式水龙头按照正规的六步洗手法进行洗手，计算使用各种水龙头洗手的耗水量和总体造价，同时调查医务人员洗手依从率，并对各种类型水龙头的优劣进行综合比较。结果5种不同类型水龙头中，脚碰式耗水量最少，平均为(932.50±319.24)mL，与其他4组比较，差异均有统计学意义(P＜0.05)；手触式水龙头造价最低，但耗水量最多［(2 258.50±363.93)mL］，且容易造成二次污染；感应式和脚踏式水龙头造价较贵（分别为606.70元/个、289.30元/个）；肘碰式水龙头使用不方便。将手触式水龙头改造为脚碰式水龙头后，医务人员洗手依从率从33.33%提高至60.00%（P＜0.05）。结论使用脚碰式水龙头可以节约成本、节约用水，且使用方便，总体优于其他4种水龙头，值得临床推广应用。

Abstract:

ObjectiveTo investigate the consumption of water running through five different kinds of faucets(foottouching, foot pedal, elbowtouching, induction, and handtouching faucet) in clinical departments, and provide basis for rational use of faucets.MethodsOne hundred health care workers(HCWs) were selected randomly and divided into 5 groups (20 /group), different types of faucets were used for sixstep handwashing, water consumption and purchase price of each type of faucet were calculated, hand hygiene compliance rate among HCWs’ was investigated and the pros and cons of all types of faucets were compared.ResultsOf 5 types of faucets, average consumption of water through foottouching faucet was the least (［932.50±319.24］mL), compared with the other four types of faucets, the difference was statistically significant（P＜0.05）. Purchase price of handtouching faucet was the lowest, but water consumption was the most(［2 258.50±363.93］mL), and can easily cause secondary pollution; purchase price of induction and foot pedal faucet was more expensive(606.70, 289.30 CNY per faucet, respectively); elbowtouching faucet was not convenient to use. After handtouching faucets were replaced by foottouching faucets, hand hygiene compliance rate of HCWs increased from 33.33% to 60.00%(P<0.05).ConclusionFoottouching faucet saves costs and water, and is convenient to use, it is better than the other four types of faucets, and is worth to be popularized in clinical application.
