Data Collection
Study staff at each site used a standardized hand hygiene data collection tool to capture hand hygiene and glove use on room entry and exit. Study staff used this form when observing HCP adherence to expected hand hygiene and glove use practice in each of the potentially eligible units (baseline period) and participating units (intervention period). A minimum number of observations was required for each study unit per month, and a randomization tool was used to balance the order of units and the time of day observed at each site. Study staff performing data collection moved to a new location or unit after 15 minutes to avoid the Hawthorne observation effect.
