BACKGROUND For alcohol-based hand rubs, the currently recommended application time of 30 seconds is longer than the actual time spent in clinical practice. We investigated whether a shorter application time of 15 seconds is microbiologically safe in neonatal intensive care and may positively influence compliance with the frequency of hand antisepsis actions. METHODS We conducted in vitro experiments to determine the antimicrobial efficacy of hand rubs within 15 seconds, followed by clinical observations to assess the effect of a shortened hand antisepsis procedure under clinical conditions in a neonatal intensive care unit (NICU). An independent observer monitored the frequency of hand antisepsis actions during shifts. RESULTS All tested hand rubs fulfilled the requirement of equal or even significantly higher efficacy within 15 seconds when compared to a reference alcohol propan-2-ol 60% (v/v) within 30 seconds. Microbiologically, reducing the application time to 15 seconds had a similar effect when compared to 30-second hand rubbing, but it resulted in significantly increased frequency of hand antisepsis actions (7.9±4.3 per hour vs 5.8±2.9 per hour; P=.05). CONCLUSION Time pressure and workload are recognized barriers to compliance. Therefore, reducing the recommended time for hand antisepsis actions, using tested and well-evaluated hand rub formulations, may improve hand hygiene compliance in clinical practice.

对于酒精类洗手液,目前推荐的 30 秒的使用时间长于临床实际使用时间。我们研究了在新生儿重症监护病房(NICU)中,15 秒的较短使用时间是否在微生物学上是安全的,并且可能会积极影响遵守手部消毒频率的情况。
我们进行了体外实验,以确定 15 秒内手部消毒剂的杀菌效果,然后在临床条件下观察临床观察,以评估在 NICU 中缩短手部消毒程序的效果。一名独立观察者在轮班时监测手部消毒操作的频率。
与 30 秒内参考的异丙醇 60%(v/v)相比,所有测试的洗手液在 15 秒内都满足等于甚至更高的功效要求。从微生物学角度来看,与 30 秒的手部揉搓相比,将使用时间缩短至 15 秒具有相似的效果,但手部消毒操作的频率明显增加(每小时 7.9±4.3 次与每小时 5.8±2.9 次相比;P=0.05)。
时间压力和工作量是合规的公认障碍。因此,减少手部消毒操作的推荐时间,使用经过测试和评估的手部消毒剂配方,可能会提高临床实践中的手部卫生合规性。感染控制与医院流行病学 2017;38:1430-1434.
