BACKGROUND: Additional evidence is needed regarding the impact of inpatient palliative care (IPC) on the quality of end-of-life care and downstream utilization.
AIM: Examine the effects of IPC on quality of end-of-life care and acute and postacute care use in a large integrated system.
DESIGN: Retrospective cohort design.
SETTING/PARTICIPANTS: Adult decedents from January 1, 2012, to December 31, 2014, who had at least one hospitalization at 11 Kaiser Permanente Southern California medical centers in the 12 months before death and not hospitalized for a trauma-related condition or receiving home-based PC or hospice were included in the cohort.
MATERIALS AND METHODS: Inverse probability of treatment weighting of propensity scores was used to compare outcomes between patients exposed to IPC (n = 3742) and controls (n = 12,755) who never received IPC before death.
RESULTS: Patients who received IPC were more likely to enroll in home-based PC or hospice (69% vs. 43%) and were less likely to die in a hospital (15% vs. 29%) or intensive care (2% vs. 9%) compared with controls (all, p < 0.001). IPC exposure was associated with higher risk for rehospitalization (HR: 1.18, 95% CI 1.11-1.25) and more frequent emergency department visits (RR: 1.16, 95% CI 1.07-1.26) with no increase in postacute care use compared with controls. Stratified analyses showed that IPC effects on acute care utilization were dependent on code status.
CONCLUSION: IPC exposure was associated with higher enrollment in home-based PC/hospice and more deaths at home. The increased acute care utilization by the IPC group may reflect persistent confounding by indication.
