Measurement and monitoring of health care workers' hand hygiene compliance (i.e., actions/opportunities) is a key component of strategies to eliminate hospital-acquired infections. Little data exist on the expected number of hand hygiene opportunities (HHOs) in various hospital settings, however. The purpose of this study was to estimate HHOs in 2 types of hospitals--large teaching and small community--and 3 different clinical areas-medical-surgical intensive care units, general medical wards, and emergency departments.
HHO data were collected through direct observations using the World Health Organization's monitoring methodology. Estimates of HHOs were developed for 12-hour AM/PM shifts and 24-hour time frames.
During 436.7 hours of observation, 6,640 HHOs were identified. Estimates of HHOs ranged from 30 to 179 per patient-day on inpatient wards and from 1.84 to 5.03 per bed-hour in emergency departments. Significant differences in HHOs were found between the 2 hospital types and among the 3 clinical areas.
This study is the first to use the World Health Organization's data collection methodology to estimate HHOs in general medical wards and emergency departments. These data can be used as denominator estimates to calculate hand hygiene compliance rates when product utilization data are available.
医护人员手部卫生依从性（即行为/机会）的测量和监测是消除医院获得性感染策略的关键组成部分。然而，关于各种医院环境中预期的手部卫生机会（HHO）数量的数据很少。本研究的目的是估计 2 种类型医院（大型教学医院和小型社区医院）和 3 个不同临床科室（内科重症监护病房、普通内科病房和急诊科）中的 HHO。
使用世界卫生组织的监测方法通过直接观察收集 HHO 数据。为 12 小时 AM/PM 班和 24 小时时间框架制定了 HHO 估计数。
在 436.7 小时的观察中，共发现 6640 个 HHO。住院病房患者每天的 HHO 估计值为 30-179 次，急诊科每床每小时为 1.84-5.03 次。2 种医院类型和 3 个临床科室之间的 HHO 存在显著差异。
本研究首次使用世界卫生组织的数据收集方法来估计普通内科病房和急诊科的 HHO。当有产品使用数据时，这些数据可作为计算手部卫生依从率的分母估计值。
