Abstract

Background: Hand hygiene is a significant component involved in preventing transmission of health care associated infections including COVID-19. Compliance to hand hygiene among the health care workers (HCWs) requires evaluation and timely feedback. "You can't improve what you can't measure" is a famous saying and this multicentric study was designed to measure hand hygiene compliance and have birds eye view on hand hygiene compliance in COVID Intensive care units (ICUs) and wards across India.

Methods: A prospective multicentric observational study was conducted for a period of 6 months in 92 health care facility across India which included varied type of public and private hospitals. Hand hygiene audit was conducted in COVID ICU and COVID non-ICU wards in all these facilities by their HCWs using the IBHAR mobile application based on WHO's hand hygiene audit tool. Hand hygiene total adherence rate (HHTAR) and hand hygiene complete adherence rate (HHCAR) were analyzed and compared between 2 locations. Adherence rates were analyzed based on the zones, institute type, profession and for each WHO moments.

Results: A total of 1,61,056 hand hygiene opportunities were documented and adherence rates were recorded higher in COVID wards (HHTAR-61.4%; HHCAR-28.8%) than COVID ICUs (HHTAR-57.8%; HHCAR-25.6%). Overall, the adherence rates were observed higher in COVID wards (HHTAR- 68.1%; HHCAR-38.3%) of private hospitals, COVID wards of the west zone (HHTAR- 70.2%; HHCAR-36.8%), cleaning staffs of the COVID ward scores better compliance than all other professions in COVID ICUs and COVID wards. HHTAR was found to be the higher in moment 3 (After body fluid exposure-76.3%) followed by moment 4 (after touching patient-73.7%) done in COVID wards compared to moments done in ICUs.

Conclusions: This study highlights the practice of hand hygiene in COVID care locations across India. Effective strategies need to be implemented in COVID ICUs across the facilities to improve the compliance.
