Palliative care delivery: descriptions of community-based services in Vellore, India, and Seattle, Washington

Exploring the rise and diversity of health and societal issues that use a public health approach: A scoping review and narrative synthesis

There is an increase in calls across diverse issues for a "public health approach" however, it is not clear whether there is any shared understanding in approach in its conceptualisation or implementation. Our aims were to (1) identify and categorise the issues which discuss a public health approach within published literature since 2010, (2) chart the descriptions and applications of public health approaches across and within four purposively sampled categories of issues, and (3) capture any evaluations conducted. A scoping review of published literature was undertaken; Seven leading databases were searched: AMED, APA PsycInfo, ASSIA, CINAHL complete, Cochrane Library (Review), Embase, and MEDLINE for articles published between 2010 and 2022 which have applied, described or called for a "public health approach" to address any issue. 3,573 studies were identified through our initial searches, of these 1,635 articles were recognised for possible inclusion from analysis of titles and abstract. The final number of included studies was 1,314. We identified 28 categories, 26 of which were societal issues, where a public health approach is being advocated. We purposively selected four of these categories; adverse childhood experiences; end of life care; gambling addiction and violence reduction/ knife crime for further analysis of the approach including how it was conceptualised and operationalised; less than 13% of the studies described the implementation of a public health approach and there was considerable heterogeneity across and within categories as to how this was done. Since 2010 there have been increasing calls for a public health approach to be taken to address health and societal challenges. However, the operationalisation of a public health approach varied extensively and there were few evaluations of the approach. This has implications for policy makers and those involved in commissioning related approaches in the future as the evidence-base is limited.

Community health workers in palliative care provision in low-income and middle-income countries: a systematic scoping review of the literature

BACKGROUND

Community health workers (CHWs) are currently deployed in improving access to palliative care in a limited number of low-income or middle-income countries (LMICs). This review therefore aimed to document evidence from LMICs regarding (1) where and how CHWs are currently deployed in palliative care delivery, (2) the methods used to train and support CHWs in this domain, (3) the evidence surrounding the costs attached with deploying CHWs in palliative care provision and (4) challenges and barriers to this approach.

METHODS

We conducted a systematic scoping review of the literature, adhering to established guidelines. 11 major databases were searched for literature published between 1978 and 2019, as well as the grey literature.

FINDINGS

13 original studies were included, all of which were conducted in sub-Saharan African countries (n=10) or in India (n=3). Ten described a role for CHWs in adult palliative care services, while three described paediatric services. Roles for CHWs include raising awareness and identifying individuals requiring palliative care in the community, therapeutic management for pain, holistic home-based care and visitation, and provision of psychological support and spiritual guidance. Reports on training context, duration and outcomes were variable. No studies conducted a formal cost analysis. Challenges to this approach include training design and sustainability; CHW recruitment, retention and support; and stigma surrounding palliative care.

CONCLUSION

Despite relatively limited existing evidence, CHWs have important roles in the delivery of palliative care services in LMIC settings. There is a need for a greater number of studies from different geographical contexts to further explore the effectiveness of this approach.
