The training and fieldwork experiences of community health workers conducting population-based, noninvasive screening for CVD in LMIC.

Background: Cardiovascular disease (CVD) is on the rise in low- and middle-income countries and is proving difficult to combat due to the emphasis on improving outcomes in maternal and child health and infectious diseases against a backdrop of severe human resource and infrastructure constraints. Effective task-sharing from physicians or nurses to community health workers (CHW) to conduct population-based screening for persons at risk has the potential to mitigate the impact of CVD on vulnerable populations. CHW in Bangladesh, Guatemala, Mexico, and South Africa were trained to conduct noninvasive population-based screening for persons at high risk for CVD.

Training and supervision of community health workers conducting population-based, noninvasive screening for CVD in LMIC: implications for scaling up.

Background: Community health workers (CHW) can screen for cardiovascular disease risk as well as health professionals using a noninvasive screening tool. However, this demonstrated success does not guarantee effective scaling of the intervention to a population level.

Objectives: This study sought to report lessons learned from supervisors' experiences monitoring CHW and perceptions of other stakeholders regarding features for successful scaling of interventions that incorporate task-sharing with CHW.
