Nurse practitioner-based models of specialist palliative care at home: sustainability and evaluation of feasibility.

CONTEXT: Patients with serious medical problems who live at home may not be able to access specialist-level palliative care when the need develops. Nurse practitioner (NP)-based models may be able to increase the availability of specialist care in the community. OBJECTIVES: The aim of this study was to evaluate the financial sustainability and feasibility of two NP-based models in an urban setting. METHODS: In one model, an NP was linked with a social worker (SW) to create a new palliative home care team (PHCT-NP-SW), which would provide consultation and direct care to referred homebound elderly patients with advanced illnesses. In a second model, an NP was assigned to a hospice program (Hospice-NP) for the purpose of enhancing the reach and impact of a home care team. The revenue generated by each model was compared with direct costs; the PHCT-NP-SW model also was evaluated for its feasibility and impact on patient-level outcomes. RESULTS: Over a two-year period, the NP in the PHCT-NP-SW model made 350 visits and followed 114 patients at home. Annualized revenue through reimbursement from patient billing offset less than 50% of the NP's salary costs. In contrast, the Hospice-NP model led to a 360% increment in hospice referrals, yielding sufficient new revenue to support this position indefinitely after only seven months. The PHCT-NP-SW model provided numerous interventions that yielded a significant decline in symptom distress during the initial two weeks after referral (P=0.003), 100% compliance with advance care planning, 21% admission rate to hospice, access to other community services, and crisis management. Nonetheless, lack of funding led to closure of this model after the two years. CONCLUSION: This experience suggests that a PHCT-NP-SW model is not sustainable in this urban environment through reimbursement-based revenue, whereas a Hospice-NP model for hospice can be sustainable based on the growth of hospice census. The PHCT-NP-SW model appears to offer benefits, and additional efforts are needed to establish the funding mechanisms to sustain such programs, create mixed models of hospice and nonhospice funding, or provide a basis for sustainability through cost reduction.
