Defining discipline roles in consultation psychiatry: the multidisciplinary team approach to psychosocial oncology.

Multiple mental health professions are often involved in the management of cancer patients. Psychiatry, psychology, social work, and nursing have all developed entrees to the medical setting that lead to clinical involvement of one or more of these professions at any given time. Much confusion remains about the specific contribution of these different mental health professions, and lack of role definition makes it difficult for programs to logically plan for mental health services or for services already in place to organize themselves in a collaborative manner. While these disciplines have interacted formally and informally in a number of settings for many years, there have been few published attempts to delineate the unique contributions of each and to suggest a model for their collaborative interaction. This paper attempts to define the unique contributions of each of these disciplines in relation to an oncology consultation program in a general hospital setting. The definitions are proposed as a model that can be generalized to other consultation programs.
