ABSTRACT
Handwashing with water and soap (HWWS) is an effective method of cleaning and disinfecting the surface of the hands. HWWS is effective in infection control and prevention transmission, such as in Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). However, rates of handwashing compliance vary globally. This systematic review aimed to identify the barriers and facilitators to community HWWS globally. We conducted a comprehensive search strategy in OVID Medline, OVID Embase, Web of Science Core Collection, and Scopus using keywords and subject headings related to handwashing. Studies were excluded if they reported hand hygiene among healthcare or food service workers, considered the use of alcohol rubs, or involved an intervention in a healthcare or food preparation setting. The quality of eligible studies was assessed using the Mixed Methods Appraisal Tool, and data were extracted from the articles and analyzed using the Theoretical Domains Framework and inductive thematic analysis. The search strategy yielded a total of 11,696 studies, and 46 studies met the eligibility criteria. Study dates ranged from 2003 to 2020 and included 26 countries; the most frequently represented were Bangladesh, India, and Kenya. A total of 21 barriers and 23 facilitators to HWWS were identified and organized into the Theoretical Domains Framework. The most frequently cited domains were environmental context and resources, goals, and knowledge. Nine themes emerged from these barriers and facilitators: resource availability, cost and affordability, handwash station design and infrastructure, accessibility, gender roles, champions, health promotion, time management, and knowledge, beliefs, and behaviors. This review uncovered multiple barriers and facilitators around a determinant framework to observe and create an in-depth, multidimensional image of a community-based hand hygiene situation. New comprehensive interventions and implementation strategies can be developed using the findings to target the contextual barriers and facilitators to improve and increase HWWS rates. Stakeholders (i.e., practitioners, researchers, policymakers) can use the findings to revise, design, or evaluate new or existing projects, interventions, and policies to improve HWWS. Registration: A protocol for this systematic review was developed and uploaded onto the PROSPERO-International prospective register of systematic reviews database (Registration number: CRD42020221210).
ABSTRACT
OBJECTIVE: The objective of this systematic review was to identify the health impact of COVID-19 on mortality, morbidity, hospital admission, and hospital readmission rates in the Black population across Canada. METHODS: A comprehensive search strategy consisting of relevant subject headings and keywords was executed in five databases: OVID Medline, OVID Embase, EBSCO CINAHL Plus, Web of Science, and Scopus. Additional searches were conducted for gray literature in ProQuest Dissertations and Theses Global, Google Scholar, and an advanced customized Google search for Canadian government documents. All eligible studies included in this review underwent quality assessment. RESULTS: Clinical health outcomes identified included mortality, morbidity, and hospital admission rates; none of the studies reported hospital readmission rates. The search identified 616 citations, and following the removal of duplicates and screening according to our inclusion/exclusion criteria, four articles were eligible for inclusion in the review. All of these studies were conducted in Canada. Study dates ranged from 2020 to 2021. CONCLUSION: A systematic review of studies on the impact of COVID-19 on the Black population in Canada highlights two key points. First, the collection and availability of race-based data are necessary to clarify the impact of COVID-19 and other diseases on Black populations in Canada. Second, with the limited available data, studies suggest that COVID-19 disproportionately impacts Black populations in Canada, making up high shares of cases, deaths, and hospitalizations compared to most of the population.
RéSUMé: OBJECTIF: L'objectif de cette revue systématique était d'identifier l'impact de la COVID-19 sur les taux de mortalité, de morbidité, d'admission à l'hôpital et de réadmission à l'hôpital dans la population noire au Canada. MéTHODES: Une stratégie de recherche complète composée des vedettes-matières et des mots-clés pertinents a été exécutée dans cinq bases de données : OVID Medline, OVID Embase, EBSCO CINAHL Plus, Web of Science et Scopus. Des recherches supplémentaires ont été effectuées pour la littérature grise dans ProQuest Dissertations and Theses Global, Google Scholar et une recherche Google personnalisée pour les documents du gouvernement canadien. Toutes les études éligibles incluses dans cette revue ont fait l'objet d'une évaluation de la qualité. RéSULTATS: Les résultats de santé cliniques identifiés comprenaient les taux de mortalité, de morbidité et d'admission à l'hôpital; aucune des études n'a rapporté de taux de réadmission à l'hôpital. La recherche a identifié 616 citations et à la suite de la suppression des doublons et de la sélection selon nos critères d'inclusion/exclusion, quatre articles étaient éligibles pour l'inclusion dans la revue. Toutes ces études ont été menées au Canada. Les dates des études allaient de 2020 à 2021. CONCLUSION: Une revue systématique des études sur l'impact de la COVID-19 sur la population noire au Canada met en évidence deux points clés. Premièrement, la collection et la disponibilité de données fondées sur la race sont nécessaires pour mieux comprendre l'impact de la COVID-19 et d'autres maladies sur les populations noires au Canada. Deuxièmement, avec les données disponibles, les études suggèrent que la COVID-19 a un impact disproportionné sur les populations noires au Canada, représentant des proportions élevées de cas, de décès et d'hospitalisations par rapport à la plupart de la population.
