Healthcare associated infections affect both patients and employees, in terms of morbidity, mortality, and financial costs. Routine hand hygiene is the most important factor against this pestilence. Hand hygiene knowledge and compliance of healthcare workers are considered poor worldwide. Herein, we aimed to measure knowledge and compliance with hand hygiene of the healthcare workers at a university hospital.
The "WHO hand hygiene knowledge questionnaire for healthcare workers" was translated in the Greek language, and was validated linguistically, culturally, and psychometrically. Reliability, content, construct, and convergent validity were measured. A survey on hand hygiene knowledge, and compliance, based on this questionnaire, was conducted on 439 employees.
The translated questionnaire presented good reliability, with Guttman's Lambda-6 evaluation (0.7). Content Validity Ratio was 84.6%. Confirmatory and exploratory factor analysis showed moderate construct validity. Convergent validity showed low correlation between the questionnaire items. Regarding the answers received, it was found that only 55.3% of the respondents received formal training on hand hygiene during the last three years prior to the study. Furthermore, 74.0% of them used alcohol-based solutions routinely. Only 54.3% of the participants presented an acceptable level of hand hygiene knowledge.
The translation and validation of the WHO questionnaire resulted in an acceptable, reliable, and valid instrument. The survey showed that hand hygiene is rather a matter of habit, than of knowledge, and that there is great need of more organized training.
医疗保健相关感染会影响患者和员工的发病率、死亡率和经济成本。常规手部卫生是对抗这种瘟疫的最重要因素。全球范围内，医护人员的手部卫生知识和依从性都被认为较差。在此，我们旨在测量一所大学医院医护人员的手部卫生知识和依从性。
将“世界卫生组织医护人员手部卫生知识问卷”翻译成希腊语，并进行语言、文化和心理计量学验证。测量了可靠性、内容、结构和收敛有效性。基于该问卷，对 439 名员工进行了手部卫生知识和依从性调查。
翻译后的问卷具有良好的可靠性，Guttman 的 Lambda-6 评估值为 0.7。内容效度比为 84.6%。验证性和探索性因素分析显示结构效度中等。收敛有效性显示问卷项目之间相关性较低。根据收到的答案，发现只有 55.3%的受访者在研究前三年接受过手部卫生的正式培训。此外，他们中有 74.0%常规使用酒精基溶液。只有 54.3%的参与者具有可接受的手部卫生知识水平。
世界卫生组织问卷的翻译和验证产生了一个可接受、可靠且有效的工具。调查显示，手部卫生更像是一种习惯问题，而不是知识问题，因此需要更有组织的培训。
