Abstract

Background: Gaps remain in our understanding of the intensity and timing of specialty palliative care (SPC) exposure on end-of-life (EOL) outcomes. Objective: Examine the association between intensity and timing of SPC and hospice (HO) exposure on EOL care outcomes. Design, Settings, Participants: Data for this cohort study were drawn from 2021 adult decedents from Kaiser Permanente Southern California and Colorado (n = 26,251). Caregivers of a decedent subgroup completed a postdeath care experience survey from July to August 2022 (n = 424). Measurements: SPC intensity (inpatient, outpatient, and home-based) and HO exposure in the five years before death were categorized as: (1) No SPC or HO; (2) SPC-only; (3) HO-only; and (4) SPC-HO. Timing of SPC exposure (<90 or 90+ days) before death was stratified by HO enrollment. Death in the hospital and potentially burdensome treatments in the last 14 days of life were extracted from electronic medical records (EMRs) and claims. EOL care experience was obtained from the caregiver survey. Results: Among the EMR cohort, exposure to SPC and HO were: No SPC or HO (38%), SPC-only (14%; of whom, 55% received inpatient SPC only), HO-only (20%), and SPC-HO (28%). For decedents who did not enroll in HO, exposure to SPC 90+ days versus <90 days before death was associated with lower risk of receiving potentially burdensome treatments (adjusted relative risk, aRR: 0.69 [95% confidence interval, CI: 0.62-0.76], p < 0.001) and 23% lower risk of dying in the hospital (aRR: 0.77 [95% CI: 0.73-0.81], p < 0.001). Caregivers of patients in the HO-only (aRR: 1.27 [95% CI: 0.98-1.63], p = 0.07) and SPC-HO cohorts (aRR: 1.19 [95% CI: 0.93-1.52], p = 0.18) tended to report more positive care experience compared to the no SPC or HO cohort. Conclusion: Earlier exposure to SPC was important in reducing potentially burdensome treatments and death in the hospital for decedents who did not enroll in HO. Increasing availability and access to community-based SPC is needed.
