Compliance with hand hygiene recommendations in hospital is typically less than 50%. Such low compliance inevitably contributes to hospital-acquired infections that negatively affect patients' well-being and hospitals' finances. The design of the present study is predicated on the assumption that most people who fail to clean their hands are not doing so intentionally, they just forget. The present study will test whether psychological priming can be used to increase the number of people who clean their hands on entering a ward. Here, we present the protocol for this study.
The study will use a randomised cross-over design. During the study, each of four wards will be observed during four conditions: olfactory prime, visual prime, both primes and neither prime. Each condition will be experienced for 42 days followed by a 7-day washout period (total duration of trial=189 days). We will record the number of people who enter each ward and whether they clean their hands during observation sessions, the amount of cleaning material used from the dispensers each week and the number of hospital-acquired infections that occur in each period. The outcomes will be compared using a regression analysis. Following the initial trail, the most effective priming condition will be rolled out for 3 months in all the wards.

医院中对手卫生建议的依从性通常低于50%。如此低的依从性不可避免地会导致医院获得性感染，对患者的健康和医院的财务状况产生负面影响。本研究的设计基于这样一种假设，即大多数不洗手的人并非故意如此，他们只是忘记了。本研究将测试心理启动是否可用于增加进入病房时洗手的人数。在此，我们展示本研究的方案。
本研究将采用随机交叉设计。在研究期间，四个病房中的每一个都将在四种情况下进行观察：嗅觉启动、视觉启动、两种启动方式以及无启动方式。每种情况将持续42天，随后是7天的洗脱期（试验总时长 = 189天）。我们将记录进入每个病房的人数以及他们在观察期间是否洗手、每周从洗手液分配器中使用的清洁材料量以及每个时期发生的医院获得性感染数量。将使用回归分析对结果进行比较。在初始试验之后，最有效的启动条件将在所有病房中推广3个月。
