# A Large-Scale Exploration of Factors Affecting Hand Hygiene Compliance Using Linear Predictive Models

## TL;DR

This large-scale study uses linear predictive models on 24.5 million hand hygiene opportunities across multiple facilities to identify key environmental and cultural factors influencing compliance rates.

## Contribution

It is the first extensive analysis revealing how environmental conditions and facility-specific cultures impact hand hygiene compliance using predictive modeling.

## Key findings

- Colder temperatures reduce compliance rates.
- Federal holidays negatively affect hand hygiene adherence.
- Facility cultures and attitudes vary significantly.

## Abstract

This large-scale study, consisting of 24.5 million hand hygiene opportunities spanning 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 residents in predicting daily hand hygiene compliance. 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 seem to exist among facilities.
