Inadequate hand hygiene (HH) by staff leads to hospital-acquired infections, high morbidity, and mortality rates for patients and a growing economic impact. The Toronto Rehabilitation Institute developed a different approach to measure and increase HH frequency, that is, a monitoring system that automatically detects HH opportunities associated with approaching and leaving patient areas. The aim of this study was to collect and classify data on HH opportunities to (1) evaluate the percentage of opportunities that the system could detect and (2) identify the system configuration.
An observational study collected time-stamped data on HH opportunities and methods of nurses on a complex care unit. Data were processed according to the Ministry of Health of Ontario, Canada. The data were subsequently classified corresponding to the motion patterns of nurses to identify areas that need to be controlled by the system.
A total of 1093 HH opportunities were recorded over 94 hours from 15 nurses, with 919 opportunities associated with entering or leaving patient environments.
The monitoring system would be able to detect and process 85% of HH opportunities in a complex care setting. To process these opportunities, the system configuration should include monitoring of patient room entrances, individual patient environments in multibed rooms, and shared ensuite bathrooms.
医护人员手部卫生（HH）不足会导致医院获得性感染，增加患者的发病率和死亡率，并对经济产生重大影响。多伦多康复研究所采用了一种不同的方法来衡量和增加 HH 的频率，即一种自动检测与接近和离开患者区域相关的 HH 机会的监测系统。本研究的目的是收集和分类 HH 机会的数据，以评估系统可以检测到的机会的百分比，并确定系统的配置。
一项观察性研究收集了复杂护理单元上护士 HH 机会和方法的时间戳数据。数据根据加拿大安大略省卫生部进行处理。随后，根据护士的运动模式对数据进行分类，以确定需要系统控制的区域。
从 15 名护士中记录了 94 小时共 1093 次 HH 机会，其中 919 次与进入或离开患者环境有关。
监测系统能够检测和处理复杂护理环境中 85%的 HH 机会。为了处理这些机会，系统配置应包括监测患者房间入口、多床房间中的单独患者环境和共用套房浴室。
