Over the past thirty years, numerous calls have been made to promote the integration of health care and services in order to control dysfunctions in health care systems. The implementation of care and service pathways has been identified as an appropriate strategy to remedy these dysfunctions. In 2015, the government of Quebec (Canada) undertook a vast reorganization of the health and social services network, leading to significant changes in the governance of health care organizations. In this context, several organizations became interested in the principle of management by care and service pathways. To support teams aiming to implement this approach, tools were developed based on the expertise of a research team, a review of scientific and grey literature, consultation with an advisory committee, and practical experimentation with a pathway management organization. This chapter presents the components and functioning of the performance analysis model that was developed and proposes an example of the performance analysis carried out. This tool has the potential to support the teams involved in achieving better demographic and clinical outcomes, a better user experience and judicious use of resources.
