To move towards universal access to health, the Pan American Health Organization recommends strengthening primary health care (PHC). One of the strategies is to increase the number qualified professionals, both medical and non-medical, working in PHC. In Chile there is a lack of professionals in this level of care, hampering the provision of health. Physicians still prefer secondary and tertiary levels of health. International experience has shown that advanced practice nurses (APN), specialists in PHC are cost-effective professionals able to deliver a complete and quality care to patients. Strong evidence demonstrates the benefits that APN could provide to the population, delivering nursing care that incorporates medical tasks, for example in patients with chronic diseases, allowing greater availability of medical hours for patients requiring more complex management. The success in the implementation of this new role requires the support of the health team, especially PHC physicians, endorsing and promoting the benefits of the APN for the population.
