Primary Health Care (PHC) teams are an important component of the health system – particularly in terms of integrating care for vulnerable patients living with complex health and social needs. Over the last two decades, PHC teams have been implemented in different forms across Canadian provinces and territories. This article explores the health care policies that shaped the form and functions of PHC team-based care in Québec over the past 20 years (2002-2022). In Québec, the main model of multidisciplinary PHC teams – Family Medicine Groups or Groupe de médecine de famille (GMFs) – were created in 2002. In 2004, structural reforms led to the creation of local health networks (LHNs). LHNs promoted coordinated and collaborative activities between health and social services providers such as GMFs located in the same geographic regions. This was followed by another structural reform of the health system in 2015, leading to the creation of broader territorial health networks with the aim to heighten coordination and collaboration among provider organizations. Various policies have strengthened the PHC team-based model. For instance, the introduction of nurse practitioners, pharmacists, and social workers with extended scopes of practice shaped the configuration of GMFs while enhancing inter-professional collaborative practices. This article highlights important insights that could advance the understanding and creation of future PHC policy initiatives.
