Building an Optimal Hand Hygiene Bundle: A Mixed Methods Approach

Brief Summary

Detailed Description

The two specific aims and associated hypotheses of CREATE Project 2 include: 1. Identify combinations of hand-hygiene intervention strategies that optimize hand-hygiene compliance and that could form an evidence-based hand-hygiene bundle for Veterans Health Administration (VHA) implementation. Hypothesis 1: Combinations of interventions will increase compliance rates more than single interventions. Aim 1 will entail a 30-month cluster-randomized controlled trial that will sequentially test three individual hand-hygiene interventions - hand-hygiene point-of-use reminder signs to serve as an environmental cue to action, individual hand sanitizers, and health care worker hand cultures - to identify an optimal combination of interventions to increase hand-hygiene compliance. The trial will be conducted in 59 hospital units in 10 VA hospitals in order to test the efficacy of individual and then sequentially added interventions to determine their incremental impact on hand-hygiene compliance. The focus for this clinical trial will be on Aim 1--Single Hand Hygiene Sign changes. 2. Identify institutional, organizational, ward/ICU, and individual level facilitators and barriers to implementing hand-hygiene interventions. Hypothesis 2: Facilitators and barriers will pattern around contextual factors such as level of leadership support and organization of infection control programs. Aim 2 will entail a qualitative process evaluation that includes site visits to purposefully selected sites, semi-structured interviews, and observations to examine barriers and facilitators to the interventions and develop contextual insight for implementing and scaling-up the intervention at additional sites as a national initiative.
