这段话是这么理解吗？

The impact of intermittent deployment of an electronic monitoring system (EMS) on the behavior of healthcare workers was investigated in a Canadian study. A smart badge collected signals on hand hygiene activity received from electronic units installed on all soap and ABHR-dispensers and on the ceilings inside and outside of all patient rooms. The badges produce real-time prompts (inaudible vibrations) to perform hand hygiene if opportunities were missed. As the results of a precursor study showed that if the same EMS is constantly deployed, participation rates (badge-use) drop considerably alongside hand hygiene compliance [23], this study investigated intermittent deployments over 1 year, hypothesizing, that the effect of being surveilled would sustain and participation would remain stable. To control compliance rate without EMS, simple counters were fitted to all soap and ABHR-dispensers unbeknown to the staff. Overall, compliance was 67% during EMS deployment but declined over the length of each deployment. Compliance assessment via the dispenser counts exposed a significant increase during EMS deployments but also a substantial reduction after the deployment phase. Dispensers located outside patients’ rooms exhibited the most count variability, being less frequently activated between deployment periods

加拿大的一项研究调查了间断使用的电子监测系统（electronic monitoring system，EMS）对医护人员行为的影响。智能标签收集手卫生活动的信号，这些信号来自安装在所有的肥皂、ABHR分配器上以及病房内外天花板上的电子装置。如果未收集到信号，标签会产生实时提示（听不见的振动）提醒你进行手卫生。EMS前期研究（假设监测的效果持续，参与率将保持稳定）调查了超过1年的间断性使用的结果显示：如果经常使用相同的EMS，参与率（标签使用）以及手卫生的依从性均会大幅下降。为了在没有EMS的情况下控制依从性，所有不为工作人员所知的肥皂和ABHR分配器都安装了简单的计数器。总体而言，EMS部署期间的依从性为67%，但随着每次部署期间延长依从性均有所下降。通过分配器计数进行的依从性评估显示，在EMS部署期间手卫生依从性显着增加，但在部署阶段之后也大幅减少。位于患者房间外的分配器表现出最大的计数变异性，在部署期间较少被激活。
