Introduction / objectives

The purpose of this study was to estimate hand hygiene opportunities (HHOs) in two types of hospitals -- large-teaching and small-community, and three different clinical areas -- medical-surgical intensive care, general medical wards, and emergency departments.


Hand hygiene opportunity data were collected through direct observations using the World Health Organization’s (WHO) monitoring methodology. Estimates of HHOs were developed for 12-hour AM/PM shifts and 24-hour time frames.


During 436.7 hours of observation, 6640 HHOs were identified. Estimates of HHOs ranged from 30 to 179 per patient day on inpatient wards and 1.84 to 5.03 per bed hour in emergency departments. Significant differences in HHOs were found between the two hospital types and between the three clinical areas.


This study is the first to use WHO data collection methodology to estimate HHO 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.
