The demographic and epidemiological changes orient health care services towards communities with a focus on prevention and health promotion. Moreover, in France, the rapid decline of General Practitioners affect access to care in certain areas. Thus, it has made a call for interaction of primary care (PC) services and public health which can be strengthened by the actions at the local level. In 2009, the local health contracts (Contract local de santé; CLS) were developed to foster collaborative actions on the social determinants of health and to improve access to care. Considering the critical contribution of PC in these issues, one may ask how CLS mobilized PC and facilitate linkages between actions oriented toward population and primary care. The objective of this ancillary study (part of the CloterreS project), is to explore how often and how CLS involve PC in access to care and public health related actions. A mixed-method study based on document analysis, with a random sample of 17 CLSs (N = 165) from all French regions, was developed. A quantitative analysis of the 440 forms identified in 17 CLS computed frequency of involvement of PC actors and/or PC organizations and a qualitative analysis defined typology of interactions. All CLS and 20.1% (n = 86) of the forms involved PC actors and 43.2% (n = 185) concerned access to care. Of the access to care forms, 35.7% (n = 66) concerned PC. The most common strategies related to actions on the health workforce and on planning of services. The role of primary care professionals was as the target of the action and rarely as leader and partner. PC, mostly GP’s involvement, had a big place and access to care was at the core of local health contracts. The impact of CLS as an instrument to invite interaction public health and healthcare at the local level should be further assessed.
