21 Million Opportunities: A 19 Facility Investigation of Factors Affecting Hand Hygiene Compliance via Linear Predictive Models
This research addresses hand hygiene compliance in healthcare settings, which is crucial for infection control, though it represents an incremental application of existing linear models to new data.
This study analyzed 21.3 million hand hygiene opportunities across 19 healthcare facilities to identify factors affecting compliance, finding that colder temperatures and federal holidays negatively impact compliance rates, with facility-specific cultures also playing a role.
This large-scale study, consisting of 21.3 million hand hygiene opportunities from 19 distinct facilities in 10 different states, uses linear predictive models to expose factors that may affect hand hygiene compliance. We examine the use of features such as temperature, relative humidity, influenza severity, day/night shift, federal holidays and the presence of new medical residents in predicting daily hand hygiene compliance; the investigation is undertaken using both a "global" model to glean general trends, and facility-specific models to elicit facility-specific insights. The results suggest that colder temperatures and federal holidays have an adverse effect on hand hygiene compliance rates, and that individual cultures and attitudes regarding hand hygiene exist among facilities.
