[Degree of compliance with hand hygiene recommendations by health care personnel in an emergency department before and after the COVID-19 pandemic.]

Objective: Hand Hygiene (HH) is the most important measure to prevent healthcare-associated infections. The aim of this study was to determine the impact of the COVID-19 pandemic on the degree of compliance (DC) of HH in an Emergency Department (ED).

Methods: Cross-sectional study. DC of HH in the ED was calculated from 2005 to 2021. We studied the association between DC of HH and different variables (age, sex, status, ED area, time of WHO, etc.) by calculating the Odds Ratio (OR) and its 95% confidence interval (95%CI). To study the impact of the pandemic, we compared the C of HH before and after the onset of the COVID-19 pandemic, calculated the OR and its 95%CI.

Results: DC of HH increased to 75.9% (95%CI: 68.6%-83.2%) in the period after pandemic onset from the previous baseline period of 48.9% (95%CI: 43.4%-54.5%) (p<0.001). Factors significantly and independently associated with DC of HH were time period (before or after pandemic), attending training sessions, having alcohol solution in pocket format and WHO moments 3,4 and 5.

Conclusions: DC of HH in the ED has reached the highest value in 17 years of monitoring following the COVID-19 pandemic. This increase reflects a very positive change in the behavior of healthcare personnel with respect to HH.
