The Impact of Advance Care Planning on End-of-Life Care: Do the Type and Timing Make a Difference for Patients With Advanced Cancer Referred to Hospice?

Purpose: This study aimed to determine the impact of advanced care planning (ACP) on potentially avoidable hospital admissions at the end of life (EOL) among a sample of hospice-referred patients with cancer, in order to present actionable considerations for the practicing clinician. Methods: This study was designed as a retrospective cohort using electronic health record data that assessed likelihood of hospital admissions in the last 30 days of life for 1185 patients with a primary diagnosis of cancer, referred to hospice between January 1, 2014, and December 31, 2015, at a large academic medical center. Inverse probability treatment weighting based on calculated propensity scores balanced measured covariates between those with and without ACP at baseline. Odds ratios (ORs) were calculated from estimated potential outcome means for the impact of ACP on admissions in the last 30 days of life. Results: A verified do-not-resuscitate (DNR) order prior to the last 30 days of life was associated with reduced odds of admission compared to those without a DNR (OR = 0.30; P < .001). An ACP note in the problem list prior to the last 30 days of life was associated with reduced odds of admission compared to those without an ACP note (OR = 0.71, P = .042), and further reduced odds if done 6 months prior to death (OR = 0.35, P < .001). Conclusions: This study shows that dedicated ACP documentation is associated with fewer admissions in the last 30 days of life for patients with advanced cancer referred to hospice. Improving ACP processes prior to hospice referral holds promise for reducing EOL admissions.
