Building successful collaborations between Public Health and Primary Health Care

Public Health (PH) and Primary Health Care (PHC) need to be better integrated, at different levels of the healthcare system, in order to improve health and social outcomes. The aim of this study was to review international models and approaches supporting the integration of PH and PHC and to classify these according to their main focus. A literature search was performed using the main scientific databases, to identify national and international journal publications regarding models to support integration between PH and PHC. The final set of the documents provided a broad coverage of the topic. Four models of integration were identified: general integration, chronic disease prevention, targeted prevention or care delivery and infection control. Models differed in their levels of implementation, stages of development and focus. This review, by classifying the main characteristics and results of the experiences retrieved, indicates a relatively scarce use of integration models in the global health care landscape, with the exception of Canada. In fact, Canada has been a leader in developing models of integrated health systems that combine tailored approaches to influence personal health behaviour and community-oriented approaches to influence the health of the population. The review also revealed a general lack of experience in evaluating the sustainability of integration between PH and PHC, not only in terms of cost-effectiveness, but also in terms of better health and work conditions and self-perceived quality of care in the population. Collaboration between PH and PHC seems to be an important strategy for achieving principles of equity and access in health care and for ensuring a more equal distribution of health care services.
