Primary Palliative Care Improves Uptake of Advance Care Planning Among Patients With Advanced Cancers.

Abstract

Palliative care specialists are experts in conducting advance care planning (ACP) but are a limited resource. Oncology nurses often have special relationships with their patients and thus may be poised to provide primary palliative care. We sought to determine the impact of a nurse-led primary palliative care intervention on ACP uptake among patients with advanced cancer. We performed a secondary analysis of a cluster randomized controlled trial examining the impact of nurse-based primary palliative care. In the parent trial, patients with advanced cancer received either monthly primary palliative care visits with trained nurses within their cancer center or standard care. Nurses in the intervention arm received special training in ACP. ACP uptake was assessed at enrollment and 3 months later evaluating (1) whether an end-of-life conversation (EOLC) occurred with one's oncologist, and (2) completion of an advance directive (AD). Multivariable logistic regression tested differences in ACP uptake by treatment arm adjusted for age, religious importance, education, time with current oncologist, and performance status. Of 672 patients enrolled, 182/336 (54%) patients in the intervention arm and 196/336 (58%) in the standard care arm lacked an EOLC at baseline and completed the 3-month assessment. Of those, 82/182 (45.1%) patients in the intervention arm and 29/196 (14.8%) in the standard care arm reported having an EOLC at 3 months (adjusted odds ratio, 5.28; 95% CI, 3.10-8.97; P<.001). Similarly, 111/336 (33%) patients in the intervention arm and 105/336 (31%) in the standard care arm lacked an AD at baseline and completed the 3-month assessment. Of those, 48/111 (43.2%) patients in the intervention arm and 19/105 (18.1%) in the standard care arm completed an AD over the study period (adjusted odds ratio, 3.68; 95% CI, 1.89-7.16; P<.001). Nurse-led primary palliative care increased ACP uptake among patients with advanced cancer. Training oncology nurses embedded within community cancer centers to provide primary palliative care may help improve ACP access.
