The hand hygiene practices of health care workers (HCWs) have long been the main vector for nosocomial infection in hospitals. The purpose of this study was to examine influences on risk judgment from the individual differences in knowledge levels and health beliefs among US HCWs.
Knowledge levels were assessed by questions taken from published questionnaires. The health locus of control scale was used to characterize internal health beliefs. HCWs assessed the risks of pathogen transfer in situations that varied according to the surface touched and the person doing the touching.
HCWs reported lower risk assessments for touching surfaces compared with touching skin. Risk assessment was influenced by individual differences, including in knowledge level and internal health locus of control.
Our data describe the individual differences of HCWs related to hand hygiene in ways that can be used to create targeted interventions and products to improve hand hygiene.
医护人员（HCWs）的手部卫生习惯一直是医院内发生医院感染的主要媒介。本研究旨在探讨美国 HCWs 个体知识水平和健康信念差异对风险判断的影响。
通过从已发表的问卷中提取问题来评估知识水平。使用健康控制源量表来描述内部健康信念。HCWs 根据触摸的表面和触摸的人来评估病原体转移的风险。
HCWs 报告说，与触摸皮肤相比，触摸表面的风险评估较低。风险评估受到个体差异的影响，包括知识水平和内部健康控制源。
我们的数据以可以用于创建有针对性的干预措施和产品以改善手部卫生的方式描述了与手部卫生相关的 HCWs 的个体差异。
