跨理论模型提升保洁人员对高频接触物体表面清洁度

Application of transtheoretical model to improve surface cleanness of frequently touched objects

目的提升保洁人员对临近患者区域高频接触物体表面清洁消毒工作的重视程度和物品表面清洁度。方法应用跨理论模型对张家港市某三级中医医院88名保洁人员进行工作行为干预,干预小组团队成员采用行为阶段性改变评估问卷对保洁人员进行测评,针对保洁人员所处的不同阶段分为5个小组,给予各期相对应的培训指导。比较干预前和干预后6个月保洁人员的行为阶段分布情况、临近患者区域高频接触物体表面荧光标记清除率和物体表面三磷酸腺苷(ATP)生物荧光检测合格率。结果干预后6个月,保洁人员行为阶段分布情况、临近患者区域高频接触物体表面荧光标记清除率和物体表面ATP生物荧光检测合格率均较干预前有明显改善,差异有统计学意义(均P<0.01)。结论基于跨理论模型的培训和干预可提高保洁人员对临近患者区域高频接触物体表面清洁工作的重视程度,从而改变工作态度和行为,更规范地做好清洁消毒工作,提高清洁有效度,减少物体表面菌落数。

Objective To improve cleaning staffers′awareness of keeping frequently touched objects clean,and enhance the cleanliness of frequently touched objects in the vicinity of patients.Methods A transtheoretical model was used to intervene the work behaviors of 88 cleaning staffers in a tertiary hospital of traditional Chinese medicine in Zhangjiagang City.The behavioral stages of cleaning staffers were assessed by the researchers;then the staffers were divided into 5 groups according to the behavioral stages they were at,and received stage-specific training and guidance.Before and 6 months after intervention,behavioral stage distribution of cleaning staffers,the clearance rate of fluorescent markers and the qualified rate of adenosine triphosphate(ATP)biofluorescence detection on the surface of frequently touched objects in the vicinity of patients were compared.Results Six months after intervention,behavioral stage distribution of cleaning staffers,the clearance rate of fluorescent markers and the qualified rate of ATP biofluorescence detection on the surface of frequently touched objects in the vicinity of patients were significantly improved,as compared to before(P<0.01 for all).Conclusion Training and intervention based on transtheoretical model can improve cleaning staffers′awareness of keeping frequently touched objects clean,make them change their attitudes towards and behaviors of cleaning work,and help standardized cleaning and disinfection work process,thus improving the efficiency of cleaning and reduce the number of bacterial colonies on the surface of objects.
