Moving away from solo practices, a new model of primary care centre was created in 2006 - a Family Health Unit (FHU). These teams have functional and technical autonomy and a payment system sensitive to performance that is designed to reward productivity, accessibility and quality, with core indicators used to measure performance and tied to the payment system. The FHUs cover primary care services, including services such as nursing services, home visits, etc. Provider participation is voluntary with set criteria on the composition and number of health professionals in each unit.
