It is lower among physicians (32%) as compared to nurses (48%), and before (21%) rather than after (47%) touching a patient.įrom a traditional point of view on human reasoning and behavior, poor hand hygiene compliance in the hospital is a conundrum. For instance, hand hygiene compliance is lower in the ICUs (30–40%) as compared to other departments. ![]() Also, a concerning degree of variation exists. For instance, a systematic analysis of 96 empirical studies has shown that median HH compliance rate in hospital settings is no more than 40%, with some studies reporting compliance under 20% or even under 10%. Still, data indicate that overall only a minority of hospital staff complies with good practice. Randomised studies on the topic are scarce, but the link between hand hygiene (HH) and nosocomial infections is well supported by the evidence and healthcare professionals are generally aware of it. According to the European Centre for disease prevention and control, 6% of patients contracts an infection during their hospital stay in the EU, with figures ranging from 2.3 to 10.8%, and 3.2 million patients are affected by nosocomial infections every year, which are fatal for 37 thousand patients. Hand hygiene among healthcare professionals plays a crucial role in preventing healthcare‐associated infections, a leading cause of mortality worldwide. If properly devised, nudging measures can provide a sustainable contribution to increase hand hygiene compliance in a hospital setting. Behavioral outcomes concerning hand hygiene in the hospital are indeed affected by contextual, nudging factors to a significant extent. An assessment of the collected data on alcohol-based hand-rub consumption indirectly confirms the main result in all experimental settings. A statistical comparison across three subsequent periods of the post-intervention phase revealed no significant decay of the effect. Improvement was observed in all experimental settings (the three hospital wards). ![]() We observed a statistically significant effect of the nudge intervention with an increase to 18.71% ( p < 0.001) in the post-intervention phase. Levels of hand hygiene compliance were low in the pre-intervention phase: 11.44% of hand hygiene opportunities prescribed were fulfilled overall. Hand hygiene compliance was measured using direct observations by trained personnel and measurement of alcohol-based hand-rub consumption. A quasi-experimental study including a pre-intervention phase and a post-intervention phase (9 + 9 consecutive months) with 117 professionals overall from three wards in a 350-bed general city hospital. Nudge theory is an innovative approach to behavioral change first developed in economics and cognitive psychology, and recently spread and discussed in clinical medicine. To assess a combined nudge intervention (localized dispensers, visual reminders, and gain-framed posters) to promote hand hygiene compliance among hospital personnel. Hand hygiene among professionals plays a crucial role in preventing healthcare‐associated infections, yet poor compliance in hospital settings remains a lasting reason for concern.
