Healthcare Utilization and Mortality After Hospice Live Discharge Among Medicare Patients With and Without Alzheimer's Disease and Related Dementias

Abstract

Background: Little is known about post-discharge outcomes among patients who were discharged alive from hospice.

Objective: To compare healthcare utilization and mortality after hospice live discharge among Medicare patients with and without Alzheimer's disease and related dementias (ADRD).

Design: Retrospective cohort study using Medicare claims data of a 20% random sample of Medicare fee-for-service (FFS) patients.

Participants: A total of 153,696 Medicare FFS patients experienced live discharge from hospice between 2014 and 2019.

Measures: Two types of burdensome transition (type 1: live discharge from hospice followed by hospitalization and subsequent hospice readmission; type 2: live discharge from hospice followed by hospitalization with the patient deceased in the hospital), acute care utilization, hospice readmission, and mortality in the 30 and 180 days after live discharge and between live discharge and death.

Results: Compared with non-ADRD patients, ADRD patients were less likely to experience burdensome transitions (type 1: adjusted odds ratio [aOR], 0.94; 95% confidence interval [CI], 0.90-0.98; type 2: aOR, 0.70; 95% CI, 0.65-0.75), more likely to have ED visits (aOR, 1.05; 95% CI, 1.01-1.09), less likely to die (aOR, 0.71; 95% CI, 0.69-0.73), and less likely to be readmitted to hospice (aOR, 0.86; 95% CI, 0.84-0.89) 30 days after live discharge. Results of 180-day post-discharge outcomes were largely consistent with results of 30-day outcomes. Among patients who died as of December 31, 2019, ADRD patients were less likely to be hospitalized (aOR, 0.88; 95% CI, 0.85-0.92) and more likely to be readmitted to hospice (aOR, 1.12; 95% CI, 1.08-1.16) between live discharge and death. Significant racial/ethnicity disparities in acute care utilization and mortality after live discharge existed in both ADRD and non-ADRD groups.

Conclusion: ADRD patients had lower mortality, a longer survival time, a lower rate of hospitalization, and an initially lower but gradually increasing rate of hospice readmission than non-ADRD patients after hospice live discharge. These different trajectories warrant further investigation of the eligibility of their initial hospice enrollment. Black patients had significantly worse outcomes after hospice live discharge compared with White patients.
