Abstract
The rising population of older Americans with advanced illness challenges current care delivery models. We use the metaphor of advanced illness as a difficult journey and propose a specific role, that of the "OACIS NP [nurse practitioner]," who helps provide a place of refuge during this journey. "OACIS" is an acronym for Optimizing Advanced Complex Illness Support, a program to provide home-based palliative medical care. The 4 pillars of this collaborative model for advanced nursing care include care coordination, medical management, psychosocial support, and education. We make the case for this expanded role for nurse practitioners who specialize in palliative care.
