The Family Health Program
A core component of the FHP was the strengthening of Brazil’s primary health care workforce through the creation of multidisciplinary Family Health Teams (FHT)."
The FHT provides comprehensive and continuous primary health care to a defined panel of patients and families, bypassing the constraints of facility-based care through integration of active community-based services.
Family Health Teams
The Brazilian model utilizes “empanelment,” a process of assigning patients to a primary health care team, as a core strategy for delivering quality care. Every individual within the FHP is assigned to a Family Health Team, and each FHT is responsible for providing services for up to 1,000 families (~4,000 individuals) located in a specific geographical area. This geographic empanelment has helped to prevent gaps in population coverage and overlap between FHTs . Continuity of care is also achieved as each FHT serves each patient over time .
The Family Health Teams include a physician, nurse, and four to six community health agents to address needs that span from community to facility and from prevention and surveillance to medical treatment. In coordination with the basic clinical staff in the FHT, separate primary health care support teams provide additional care to empaneled populations. These support teams can include nutritionists, social workers, psychologists, obstetricians and gynecologists, and public health workers . Since 2000, Brazil has recruited 250,000 CHAs and 30,000 family physicians who form the core of the 29,000 FHTs now in service . Many of these physicians had to be hired from abroad to address the country’s massive shortage of doctors and health care professionals.
Community Health Agents
Community health agents (CHAs) play critical roles as key members of the FHTs. CHAs are recruited from the facilities in which they reside and complete up to three months of training by the municipality . CHAs focus on primary and secondary prevention including promotion of a healthy lifestyle and health education, and early detection screening programs for hypertension, diabetes, and other prevalent conditions . CHAs also serve as a first point of access for services, connecting patients to needed preventative and curative treatment.
Within an FHT, each CHA is assigned to a small “micro-area” that includes approximately 150 families . Agents visit the homes of each family in their micro-area monthly, even if the family has not reported any health concerns . During these visits, CHAs provide basic preventative care including screening for common conditions like diabetes and hypertension, promotion of treatment adherence, and health education tailored to the needs of the family [3, 4]. Additionally, CHAs collect vital data, such as marriages, births, deaths, and disease incidence .
CHAs identify and then refer high-risk patients to the clinical team for treatment and then coordinate with clinicians to ensure that patients adhere to the treatment, attend follow-up appointments, and complete rehabilitation [7, 8]. Clinicians generally include a doctor, nurse, and medical assistant. The agents and clinicians collaborate to ensure care coordination and disease management for patients . For example, if a patient is recommended exercise to treat a chronic condition, the CHA develops strategies for the patient to incorporate exercise into their lifestyle and stay motivated. Because CHAs live in the same communities where they work, they often form strong relationships with the families they serve.
This connection enables the agent to look beyond medical diagnosis and promote holistic health and wellbeing. CHAs connect families to social welfare programs to address barriers to health and healthcare access and overall well-being."
For example, agents can refer families to conditional cash transfer programs, welfare organizations, and other social services for issues such as housing or domestic violence .
The CHAs also perform disease surveillance, which enables them to better treat individuals in their micro-area as well as understand the needs of their micro-area as a whole. In a systematic manner, CHAs seek to identify and record new incidences of illness and disease so that public health and primary care services can be tailored to the needs of the population. This system is a vast improvement from the passive reporting system in place before the FHP. 
Greater accessibility, fewer disparities
However, the FHP has been slow to operationalize in the large urban centers of Brazil where most of the uncovered population lives [3, 9]. In order to expand coverage of FHP, Brazil will need to overcome a persistent shortage of well-trained health care workers. Additionally, the FHP still struggles with the communication and referral processes needed to vertically integrate primary, secondary, and tertiary health services [3, 4].
Despite its challenges in reaching scale in urban areas, the model has been effective in addressing health disparities, with the most dramatic improvements seen in the poorest municipalities [3, 8, 13, 14, 16]. Overall, FHP has led to substantial improvements in service coverage and health outcomes in the last 20 years:
- The percent of women who complete antenatal care has increased to 75 percent
- Vaccine coverage has increased to 95 percent 
- Hospital admissions due to diabetes have decreased by 25 percent
- Pediatric and adult hospital admissions due to ambulatory care sensitive conditions decreased by nearly 20 percent
- Hospital admissions due to cardiovascular disease have also fallen [4, 6, 7, 12-15]
- The percent of children under-five who are underweight decreased by 67 percent
- Child mortality has decreased and infant mortality has decreased by 64 percent
- Mortality from cardiovascular disease has also decreased [3, 4, 6, 8, 16-19]
