Faced with the fragmentation of the French primary care system, public policies aim to promote multiprofessional teamwork to improve both delivery efficiency and health professionals' working conditions. Thus, a practice-level add-on payment backed by cooperation commitments is implemented to foster and sustain the development of multiprofessional primary care groups (MPCGs). We study the impact of practising in MPCGs for general practitioners (GPs) in terms of the supply of care, practice patterns and income. Based on this quasiexperimental framework with a panel dataset covering the period 2005-2017, we account for the selection into MPCGs by combining a difference-in-differences design with propensity score matching to prebalance samples. We show that GPs in MPCGs increased their patient list more rapidly than control GPs (+10% increase of encountered patients) without increasing their provision of services (number of visits and drug prescriptions) more rapidly. Instead, compared to control GPs, MPCG GPs had a significantly faster reduction in the average number of visits (+5.5% reduction) and the euro-amounts of drug prescriptions per patient (+7.2% reduction) and other prescriptions. The growth of these effects between the short and medium term moreover suggests that the properties of multi-professional coordination and cooperation need time to develop.
