Allied and clinical mental health case management is a systems-of-care and strength-based model of care that transcends professional affiliations. Systems-of-care and strength-based approaches are framed by addressing the full scope of the health needs of the patient or client across areas of activity and participation and capitalizing on the patient or client's resources for health recovery while maintaining the efficient use of treatment care resources. The successful implementation of a systems-of-care and strength-based model of care by allied and clinical mental health case managers depends on the use of appropriate training, and skills as well as a case referral system that minimizes service discontinuities. This chapter presents a systems-of-care and a strength-based approach to allied health case management likely to result in superior mental health function and well-being for patients or clients, their families or significant others, and care providers.
