[Community health worker: a core element of health actions].

This research sought to identify the actions developed by the Community Health Worker (CHW) in the context of family health in Montes Claros, State of Minas Gerais, Brazil. The research was conducted under the Program of Education through Work for Health-PET-SAÚDE, and is a quantitative study and census together with 241 CHWs. Most of them make family registrations and home visits, identify families with health risks and inform the health team. They also instruct families about available health services, arrange referrals and schedule consultations/exams, perform health education and teamwork reflections. Some also assist in the clinical environment. The majority who provide health education and those who are responsible for the referrals feel that they are professionally qualified for such tasks. CHWs are a core element of health actions, but the scope of performance requires investment in professional training to maintain the quality of the work executed by them in surveillance activities and teamwork reflection. In this way, the CHW can be jointly responsible for primary care and integrate the system of health care administration.
