Impact of Palliative Care Referral on End-of-Life Outcomes for Patients With Hematologic Malignancy

ContextCompared to patients with solid malignancies, less is known about the role of palliative care in patients with hematologic malignancies, leading to underutilization of palliative care.ObjectivesEvaluate the timing and impact of palliative care referrals on end-of-life outcomes over a 5-year period with intent to improve the utilization of palliative care in patients with advanced hematologic malignancies.MethodsA retrospective cohort of patients from an urban, NCI-designated comprehensive cancer center, aged 18 years and older with a diagnosis of an advanced hematologic malignancy were separated into groups of early, late, very late, or no specialty palliative care. Logistic regression models were constructed to examine variables associated with timing of palliative care referral. Groups were compared using the Kruskal Wallis test and Dunn's test with a Bonferroni correction method.Results222 patients with advanced hematologic malignancies who died between July 1, 20218 and June 30, 2023 were included. 50 (23%), 41 (18%), and 51 (23%) patients received an early, late, and very late palliative care referral, respectively and 80 (36%) patients did not receive a palliative care referral. There was a significantly high completion of ACP documentation among the palliative care cohorts. There was no significant difference among all cohorts in end-of-life outcomes in the last 14 or 30 days of life.ConclusionACP documentation improved with palliative care, however, end-of-life outcomes did not. These results are likely due to the majority of late, inpatient palliative care referrals. Future studies with targeted interventions are needed to improve these outcomes.
