The role of community health workers in primary healthcare in the WHO-EU region: a scoping review

BACKGROUND

Existing evidence on the role of community health workers (CHWs) in primary healthcare originates primarily from the United States, Canada and Australia, and from low- and middle-income countries. Little is known about the role of CHWs in primary healthcare in European countries. This scoping review aimed to contribute to filling this gap by providing an overview of literature reporting on the involvement of CHWs in primary healthcare in WHO-EU countries since 2001 with a focus on the role, training, recruitment and remuneration.

METHODS

This systematic scoping review followed the guidelines of the Preferred Reporting Items for Systematic reviews and Meta-Analyses, extension for Scoping Reviews. All published peer-reviewed literature indexed in PubMed, Web of Science, and Embase databases from Jan 2001 to Feb 2023 were reviewed for inclusion. Included studies were screened on title, abstract and full text according to predetermined eligibility criteria. Studies were included if they were conducted in the WHO-EU region and provided information regarding the role, training, recruitment or remuneration of CHWs.

RESULTS

Forty studies were included in this review, originating from eight countries. The involvement of CHWs in the WHO-EU regions was usually project-based, except in the United Kingdom. A substantial amount of literature with variability in the terminology used to describe CHWs, the areas of involvement, recruitment, training, and remuneration strategies was found. The included studies reported a trend towards recruitment from within the communities with some form of training and payment of CHWs. A salient finding was the social embeddedness of CHWs in the communities they served. Their roles can be classified into one or a combination of the following: educational; navigational and supportive.

CONCLUSION

Future research projects involving CHWs should detail their involvement and elaborate on CHWs' role, training and recruitment procedures. In addition, further research on CHW programmes in the WHO-EU region is necessary to prepare for their integration into the broader national health systems.

A meta-ethnography of participatory health research and co-production in Nepal

As global health research seeks to decolonialise, democratise, and become more culturally engaging, researchers are increasingly employing participatory and co-productive methods. Working from post-structural perspectives, this meta-ethnographic review explores how such health research in Nepal engages with the epistemological, methodological, and ethical questions it encounters. Five databases including Nepali NepJOL were searched for studies from inception to March 2021. The review included seven studies covering women's group co-production, interviews guided by photo-elicitation, observational methods to explore maternal and child health, mental health, and environmental determinants of health. This meta-ethnography identified that, against the background of a pluralist heritage of health practices, global collaborations involving Nepali researchers and practitioners used participatory research methodology to work with the local populations to improve health and co-production seek primarily to promote Western biomedical and psychosocial interventions. Both advantages and disadvantages were acknowledged. Empirical verification and global acceptance of Western biomedical and psychosocial knowledge were seen as beneficial. Moreover, Western biomedicine was perceived by some as more effective than some local practices in improving health; nevertheless, Nepal faces many challenges that neither can address alone. For participatory and co-productive approaches to become epistemologically enculturated within Nepali health research, researchers need to co-develop more local models and methods which are culturally sensitive and appropriate. Meaningful and effective participatory research can promote active involvement of people who deliver as well as people who use the community-based health care support. These are crucial to optimise sustainable change that global health research partnerships set out to achieve. This meta-ethnography recommends that researchers engage at a deeper level with the epistemological differences between themselves and the communities with whom they seek partnership. Cross-cultural research teams should discuss and address the power differentials which might affect them.
