Collaborative Mental Health Care Model: an Evaluation of the Implementation of a Pilot in Four Health Homes

Frequent mental disorders (anxiety or mood disorders), an important part of primary care patient care, remain insufficiently detected and treated. Improving their care requires better coordination between general practice and specialized care. The collaborative care model developed in Washington State with the introduction of a care manager is recognized. About 100 randomized controlled trials have established its effectiveness and efficiency, in terms of improving the progression of disorders (remission rate), adherence, quality of life, professional and patient satisfaction, and cost savings. However, the possibility of implementation of these validated care remains to be explored. A dozen collaborative care implementation studies exist, all conducted in the USA and not having considered all the dimensions of the indicators of penetration, acceptability/adoption, feasibility, fidelity and cost. A first implementation in France is implemented since September 2021 in the Yvelines department on four sites of different size, organization and environments: the multi-professional health centers (MSP) of Mureaux and Celle St Cloud, the Chevreuse medical house and MG in isolated practice in Versailles.

The main objective of the research project is to evaluate the first implementation in France of collaborative care for frequent psychic disorders according to the indicators of penetration, acceptability/adoption, fidelity, relevance, feasibility and cost.
