Hand hygiene and HAI transmission in Piedmont, Italy: an observational study, 2017-2019

Sumario: | BACKGROUND: Hand hygiene (HH) is one of the most important measures to prevent healthcare-associated infections (HAIs). Several indicators have been proposed to measure HH practices, including alcohol-based handrub consumption (AHC). The objective of this study was to evaluate whether AHC is associated with HAI transmission. METHODS: All 25 public hospitals/trusts of Piedmont, in Northern Italy, are required to provide data each year concerning HAIs and infection prevention and control (IPC) activities, as part of a mandatory regional indicator system. Data on AHC and HAIs were extracted from reports provided concerning the years 2017-2019. The mean annual AHC for each facility was expressed as liters per patient-day. The rate of hospital-wide Methicillin-resistant Staphylococcus aureus (MRSA) and carbapenem-resistant Enterobacteriaceae (CRE) infections was calculated per 1000 patient-days (pd). Mean ventilation-associated infections (VAP) for 1000 days of ventilation (vd) and mean catheter-related bloodstream infections (CR-BSI) for 1000 days of catheterization (cd) were calculated for intensive care units (ICUs). Spearman's correlational analysis was conducted between AHC and HAIs: hospital-level, ICU-level. RESULTS: Hospital-level: mean AHC was 15.4 liters/pd; mean HAI rate was 39.6/1000 pd (MRSA) and 18.5/1000 pd (CRE). No significant correlation was found. ICU-level: mean AHC was 39.6 liters/pd; mean HAI rate was 1.7/1000 cd (CR-BSI) and 8.2/1000 vd (VAP). A moderate correlation was found between AHC and CR-BSI rate (Spearman's ρ -0.55, p 0.022). Concerning AHC and VAP, higher AHC was reported from facilities with lower VAP rates, however no significant correlation was found (Spearman's ρ -0.203, p 0.451). CONCLUSIONS: Results of this study support the validity of AHC as an indicator of IPC practices in ICUs. The hospital-level analysis could have been affected by important differences in AHC among ward types. KEY MESSAGES: Results of this study support the association between higher AHC and reduced HAI transmission in intensive care units. Stratifying data by ward type could provide further insight in the association between AHC and HAI rates. |
