Association of palliative care and hospital outcomes among solid tumour oncology inpatients

ObjectivesWe aimed to explore the association between receiving an inpatient palliative care consultation and hospital outcomes, including in-hospital death, intensive care unit (ICU) use, discharge to hospice, 30-day readmissions and 30-day emergency department (ED) visits. MethodsWe conducted a retrospective chart review of Yale New Haven Hospital medical oncology admissions from January 2018 through December 2021, with and without inpatient palliative care consultations. Hospital outcome data were extracted from medical records and operationalised as binary. Multivariable logistic regression was used to estimate ORs for the association between number of inpatient palliative care consultations and hospital outcomes. ResultsOur sample included 19 422 patients. Age, Rothman Index, site of malignancy, length of stay, discharge to hospice, ICU admissions, hospital death and readmissions within 30 days differed significantly between patients who received versus did not receive a palliative care consultation. On multivariable analysis, receiving one additional palliative care consultation was significantly associated with higher odds of hospital death (adjusted OR=1.15, 95% CI 1.12 to 1.17) and discharge to hospice (adjusted OR = 1.23, 95% CI 1.20 to 1.26), and lower odds of ICU admission (adjusted OR=0.94, 95% CI 0.92 to 0.97). There was no significant association between palliative care consultations and readmission within 30 days or with ED visits within 30 days. ConclusionInpatients receiving palliative care had increased likelihood of hospital death. However, when controlling for significant differences in patient presentation, patients had nearly 25% greater odds of discharge to hospice and less odds to transition to ICU level of care.
