Hand hygiene (HH) is a cost-effective measure to reduce healthcare-associated infections. The overall characteristics and changes of hand hygiene compliance (HHC) among healthcare providers during the COVID-19 pandemic provided evidence for targeted HH intervention measures.To systematically review the literature and conduct a meta-analysis of studies investigating the rate of HHC and the characteristics of HH during the COVID-19 pandemic.The PubMed, Embase, Cochrane Library, Web of Science, CNKI, WanFang Data, VIP and CBM databases were searched. All the original articles with valid HHC data among healthcare providers during the COVID-19 pandemic (from January 1, 2020 to October 1, 2021) were included. Meta-analysis was performed using a DerSimonian and Laird model to yield a point estimate and a 95% CI for the HHC rate. The heterogeneity of the studies was evaluated using the Cochrane Q test and I2 statistics and a random-effects model was used to contrast between different occupations, the WHO five-moments of HH and different observation methods. Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines were followed.Seven studies with 2377 healthcare providers reporting HHC were identified. The estimated overall HHC was 74%, which was higher than that reported in previous studies (5%-89%). Fever clinic has become a new key place for HHC observation. Nurses had the highest HHC (80%; 95% CI:74%-87%) while auxiliary workers (70%; 95%CI:62%-77%) had the lowest. For the WHO five-moments, the healthcare providers had the highest HHC after contact with the body fluids of the patients (91%; 95% CI:88%-94%), while before contact with patients healthcare providers had the lowest HHC (68%; 95% CI:62%-74%) which was consistent with before the pandemic. There existed great HHC differences among different monitoring methods (automatic monitoring system:53%; 95% CI:44%-63% vs openly and secretly observation: 91%; 95% CI: 90%-91%).During the COVID-19 pandemic, the compliance of healthcare providers' HH showed a great improvement. The fever clinics have become the focused departments for HH monitoring. The HHC of auxiliary workers and the HH opportunity for "before contact with patients" should be strengthened. In the future, it will be necessary to develop standardized HH monitoring tools for practical work.Copyright © 2021 The Authors. Published by Elsevier Inc. All rights reserved.
