COVID-19 outbreak and healthcare worker behavioural change toward hand hygiene practices.

BACKGROUND

The coronavirus disease (COVID-19) pandemic has affected healthcare workers (HCWs) in their clinical practice. HCWs were challenged with new guidelines and practices to protect themselves from occupational risks.

AIM

To determine whether hand hygiene behaviour by real-time measurement was related to the dynamic of the epidemic, and the type of patient being cared for in France.

METHODS

This study used an automated hand hygiene recording system to measure HCW hand hygiene on entry to and exit from patient rooms throughout the COVID-19 pandemic. The correlation between hand hygiene compliance and COVID-19 epidemiological data was analysed. Analysis of variance was performed to compare compliance rate during the different periods of the epidemic.

FINDINGS

HCW hand hygiene rate on room entry decreased over time; on room exit, it increased by 13.73% during the first wave of COVID-19, decreased by 9.87% during the post-lockdown period, then rebounded by 2.82% during the second wave of the epidemic. Hand hygiene during patient care and hand hygiene on room exit had a positive relationship with the local COVID-19 epidemic; conversely, hand hygiene on room entry did not depend on the trend of the epidemic, nor on nursing of COVID-19 patients, and it decreased over time.

CONCLUSION

HCWs modified their behaviours to face the risk propensity of the pandemic. However, to improve the poor compliance at room entry, reducing confusion between the hand hygiene recommendation and glove recommendation may be necessary; disinfection of gloving hands might solve this issue.
