OBJECTIVES Hand hygiene is essential for infection prevention. In Piedmont (Northwest Italy), hand hygiene is routinely monitored through 2 surveillance systems, the World Health Organization Hand Hygiene Self-Assessment Framework (HHSAF) and alcohol-based hand rub (ABHR) consumption. This study was aimed at (1) comparing the results of these surveillances, investigating the consistence of the 2 systems and (2) inquiring whether organizational differences among healthcare facilities significantly affected hand hygiene performances. METHODS A retrospective analysis was performed on data collected annually from 2015 to 2018 for both surveillances from 40 hospitals of the region: HHSAF score (500 points maximum) and ABHR consumption in milliliters per patient-day (mL/PD) were considered. Logistic regression models were built to evaluate possible correlations between these variables, and observations were clustered considering both variables to identify whether groups with significant differences could be discerned. A tree-structured partitioning model was used to confirm the obtained results. RESULTS A positive correlation was observed between HHSAF score and odds of belonging to the high ABHR consumption group, particularly for cutoffs set to 19 to 23 mL/PD (P = 0.033 for 23 mL/PD). Two ABHR consumption peaks were identified at approximately 10 and 22 mL/PD, corresponding to median HHSAF scores of 353.75 and 375 points, respectively. The group with better performances was mainly composed of hub hospitals (with single-hospital management). CONCLUSIONS The 2 surveillance systems are consistent, and the HHSAF score could work as a reasonable predictor of hand hygiene compliance in healthcare settings. Different management characteristics are crucial in creating a more/less favorable environment for hand hygiene compliance and infection prevention.
