The Evolution, Expansion, and Effectiveness of Community Health Workers

In the past decade, the community health worker (CHW) profession in the United States has increased its visibility, but its potential contributions remain underappreciated and more permanent financing is elusive. This paper describes the current state of knowledge about how and where CHWs can contribute effectively, where barriers inhibit efficient deployment of CHWs, and what business models could support change.

Cell phones and CHWs: a transformational marriage?

Community health workers (CHWs) have a key role to play if we are to achieve our ambitious goals to reduce child and maternal mortality globally. A wide diversity of CHW cadres have been established in many countries, both in the public sector and with nongovernmental organizations, yet several major challenges have emerged. Mobile phones can be transformative for community health workers (CHWs) in enhancing their influence and status and helping to solve practical problems.

Working with Community Health Workers as 'volunteers' in a vaccine trial: Practical and ethical experiences and implications

Community engagement is increasingly emphasized in biomedical research, as a right in itself, and to strengthen ethical practice. We draw on interviews and observations to consider the practical and ethical implications of involving Community Health Workers (CHWs) as part of a community engagement strategy for a vaccine trial on the Kenyan Coast. CHWs were initially engaged as an important network to be informed about the trial.

The impact of community health workers (CHWs) on Buruli ulcer in sub-Saharan Africa: a systematic review.

Buruli ulcer (BU) is a cutaneous neglected tropical disease caused by Mycobacterium ulcerans. Participation of Community Health Workers (CHWs) is an integral part of the management of BU, yet their impact has not been systematically evaluated in sub-Saharan Africa. Our objectives were to summarize the evidence on the impact of CHWs on the control of BU in sub-Saharan Africa by looking at their recruitment, training, non-governmental support and performance. For the management of Buruli Ulcer, CHWs are often recruited from the communities they will serve.

Cost-effectiveness of community health worker versus home-based guardians for directly observed treatment of tuberculosis in Vitória, Espírito Santo State, Brazil

The objective of this study was to compare the costs and outcomes associated with guardian-supervised directly observed treatment relative to the standard of care Directly Observed Therapy, Short Course (DOTS) provided by community health workers (CHW). New cases of culture-positive pulmonary tuberculosis (TB) treated in Vitória, Espírito Santo State, Brazil were interviewed and chose their preferred treatment strategy. Costs incurred by providers and patients (and patients' families) were estimated, and cost-effectiveness was assessed by comparing costs per successfully treated patient.

The Mexican-American Trial of Community Health workers (MATCH): design and baseline characteristics of a randomized controlled trial testing a culturally tailored community diabetes self-management intervention.

Community Health Workers (CHWs) have been recommended to reduce diabetes disparities, but few robust trials of this approach have been conducted. Limitations of prior studies include: unspecified a priori outcomes; lack of blinded outcome assessments; high participant attrition rates; and lack of attention to intervention fidelity. These limitations reflect challenges in balancing methodologic rigor with the needs of vulnerable populations.

The Tingathe programme: a pilot intervention using community health workers to create a continuum of care in the prevention of mother to child transmission of HIV (PMTCT) cascade of services in Malawi.

Loss to follow-up is a major challenge in the prevention of mother to child transmission of HIV (PMTCT) programme in Malawi with reported loss to follow-up of greater than 70%. Tingathe-PMTCT is a pilot intervention that utilizes dedicated community health workers (CHWs) to create a complete continuum of care within the PMTCT cascade, improving service utilization and retention of mothers and infants.

Designing a community-based lay health advisor training curriculum to address cancer health disparities.

Racial and ethnic minorities have disproportionately higher cancer incidence and mortality than their White counterparts. In response to this inequity in cancer prevention and care, community-based lay health advisors (LHAs) may be suited to deliver effective, culturally relevant, quality cancer education, prevention/screening, and early detection services for underserved populations.
