L’objectif de l’étude était de déterminer la variation diurne du respect de l’hygiène des mains chez différentes catégories de travailleurs de la santé dans un hôpital de soins tertiaires du nord de l’Inde.

Background Hand hygiene compliance (HHC) monitoring is almost always done in daytime. Documentation of HHC in healthcare workers (HCWs) is limited during odd hours and nighttime. Aim The objective of the study was to determine diurnal variation in HHC in different categories of health care workers in tertiary care hospital in North India. Methods A prospective, observational study was conducted in three COVID-19 intensive care units (ICUs) with closed-circuit television (CCTV) cameras. Dedicated infection control nurses monitored HHC among various HCWs (doctors, nursing staff, technicians, hospital and sanitary attendants) during day and nighttime, in 20- minute durations. The difference in HHC by-professional category and for each WHO moment was assessed using chi-square test and p value. Findings A total of 705 opportunities were observed over a period of seven days, with overall compliance of 53%. Day and nighttime compliance was recorded to be 60.7% and 42.1%, respectively (p<0.001). HCC was highest amongst resident doctors with little diurnal variation. However, nurses and housekeeping staff exhibited significant diurnal variation. The compliance at “after” moments was much higher than “before” moments in all professional categories. Conclusion There was a significant decrease in compliance during nighttime, amongst all HCWs, with maximum variation exhibited by nursing staff. The present study underlines the importance of monitoring HHC at odd hours, to elicit a more accurate picture round the clock. Healthcare facilities monitoring compliance only during the daytime may substantially overestimate HHC. Lisez l’article
