The advanced practice nurse as case manager.

The dynamic interactions of the client, service provided, and payer are complex relationships in today's health care environment. An advanced practice nurse's abilities to care physically and psychosocially for clients and their families are essential within the case management framework. With a holistic view of clients' health status, the nurse case manager develops and carries out advanced practice functions that help achieve the best outcome for the client through effective interactions with clients, payers, and providers. Those functions, illustrated by the Star Case Management Model, include interpretation, advocacy, and surveillance.
