We aimed to study the effect of visual observation of bacterial growth from handprints on healthcare workers' (HCWs) compliance with hand hygiene (HH).
Medical and postoperative cardiac surgery units.
Prospective cohort study.
The study included 40 HCWs.
Each HCW was interviewed on 3 separate occasions. The 1st interview was held to obtain a handprint culture before and after a session demonstrating the 7 steps of HH using alcohol-based hand rub, allowing comparison of results before and after HH. A 2nd interview was held 6 weeks later to obtain handprint culture after HH. A 3rd interview was held to obtain a handprint culture before HH. One month before implementation of handprint cultures and during the 12-week study period, monitoring of HCWs for compliance with HH was observed by 2 independent observers.
There was a significant improvement in HH compliance following handprint culture interview ( < 0.001). The frequency of positive cultures, obtained from patients with suspected healthcare-associated infections, significantly declined (blood cultures: = 0.001; wound cultures: = 0,003; sputum cultures: = 0.005).
The visual message of handprint bacterial growth before and after HH seems an effective method to improve HH compliance.
我们旨在研究通过观察手印上细菌生长情况对医护人员手部卫生（HH）依从性的影响。
内科及心脏外科术后病房。
前瞻性队列研究。
该研究纳入了40名医护人员。
每位医护人员在3个不同时间接受访谈。第一次访谈是在使用酒精擦手液演示手部卫生7步法前后获取手印培养物，以便比较手部卫生前后的结果。6周后进行第二次访谈以获取手部卫生后的手印培养物。第三次访谈是在手部卫生前获取手印培养物。在实施手印培养前1个月以及为期12周的研究期间，由2名独立观察员对手医护人员手部卫生依从性进行监测。
手印培养访谈后手部卫生依从性有显著改善（<0.001）。从疑似医疗相关感染患者中获得的阳性培养物频率显著下降（血培养：=0.001；伤口培养：=0.003；痰培养：=0.005）。
手部卫生前后手印细菌生长的直观信息似乎是提高手部卫生依从性的有效方法。
