This chapter discusses different aspects of case management and coordination of care beginning with general guidelines and a review of legal and ethical issues. It examines specific issues that arise in integrated care settings, in coordinating with health care and other helping professionals, in obtaining records from others, and in working with family members. Integrated care has been shown to be especially effective in treating individuals with co-occurring mental health and substance use disorders. Integrated care is provided by a multidisciplinary team that may include a psychotherapist, case manager, psychiatrist or nurse practitioner, addiction specialist, family advocate, and social worker. When care is provided by a multidisciplinary team, clients are asked to authorize exchange of information among members of the team as part of their consent for treatment. This allows members of the team to share information as a group or individually to coordinate the client's care.
