不同清洗频率对减少医院病床隔帘病原菌的成本效益分析

Cost-effectiveness analysis of different cleaning frequency on reducing pathogens on hospital bed-side curtains

目的探讨不同清洗频率下医院病床隔帘携带病原菌情况及成本效应。方法选取某院2023年1-6月感染相对高发且发病率波动较小的14个科室,每个科室抽取9个病室,每个病室2片隔帘,按照清洗频率将病室划分为低频、中频、高频组。比较6个月后床旁隔帘表面环境卫生学检测合格率、菌株污染等情况,并进行成本效应分析。结果高频组床旁隔帘环境卫生学检测合格率最高,为88.10%。高频组床旁隔帘上、中、下位置表面菌落数均最低(P<0.05)。6个月内,高频组、中频组对应的住院患者医院感染发病率(分别为0.16%、0.25%)均低于低频组的0.85%(χ^(2)值分别为5.653、3.915,均P<0.05)。成本效益分析显示高频组、中频组每增加1个单位的合格率,费用分别增加124.51、44.10元。结论清洗频率的增加可有效减轻普通病房床旁隔帘的细菌污染,降低医院感染风险,提高病床隔帘环境卫生学合格率,间隔2个月清洗一次可获得较佳的成本效益。

Objective To explore the pathogen contamination and cost-effectiveness of hospital bed-side curtains under different cleaning frequencies.Methods Fourteen departments in a hospital with relatively higher incidence but smaller fluctuation of incidence of infection from January to June 2023 were selected.Nine wards in each department were selected,and two curtains were selected from each ward.According to the cleaning frequency,wards were divided into low,medium and high frequency groups.The qualified rate of environmental hygienic detection on pathogens on the bed-side curtains and bacterial contamination on the surface of curtains after 6 months were comparted,cost-effectiveness analysis was conducted.Results The qualified rate of environmental hygienic detection of bed-side curtains was the highest in high frequency group,at 88.10%.Bacterial counts on the upper,middle,and lower segments of the bed-side curtains in the high frequency group were all lowest(P<0.05).Within 6 months,the incidence of healthcare-associated infection(HAI)in patients in the high and the medium frequency groups(0.16%and 0.25%,respectively)were both lower than 0.85%in the low frequency group(χ^(2)=5.653,3.915,respectively,both P<0.05).Cost-effectiveness analysis showed that for every additional unit of qualified rate for the high and medium frequency groups,the costs increase by 124.51 and 44.10 Yuan,respectively.Conclusion The increase of cleaning frequency can effectively reduce bacterial contamination of bed-side curtains,decrease the risk of HAI,and improve the qualified rate of environmental hygiene of bed-side curtains in the wards.Cleaning once every 2 months can achieve better cost-effectiveness.
