Intensive Case Management is part of the Social integration measures. Although there are similarities between Assertive Community Treatment (ACT) and Intensive Case Management (ICM) programs, the services are delivered differently: ACT services are provided by an interdisciplinary team versus intensive case management services which are provided by a single case manager.

Intensive Case Management is intended for people with a serious mental illness, but for whom the functional disabilities and difficulties are less serious. In this case, the services offered target the development of individual skills and support. The caregiver offering this service is the «case manager» that provides rehabilitation and support and establishes a relationship based on trust and respect with the person receiving the service. The intensive case manager coordinates services, establishes links with the person being treated and ensures his presence even if he does not offer himself all the services needed by the person (PASM 2015-2020).

Intensive case management responds to consumers’ multiple and changing needs, and plays a pivotal role in coordinating required services from across the mental health system as well as other service systems (criminal justice, developmental services, and addictions).
