IntroductionPatients with hematologic malignancies (HMs) often face challenges in accessing palliative care (PC) and receiving quality end‐of‐life (EOL) care. We examined factors associated with referrals to tertiary PC and the effects of tertiary PC on EOL care in patients with HMs.MethodWe included patients with HMs who were admitted to a university‐affiliated hospital and died during hospitalization between January 2018 and December 2021. We investigated the receipt of PC consultations, patient characteristics, and EOL care indicators.ResultsOverall, 487 patients were included in the analysis, with 156 (32%) undergoing PC consultation. Sex, residence, disease status, and admission purpose were factors associated with the likelihood of PC consultation, and there has been an increasing trend in the frequency of consultations in recent cases. A higher proportion of patients who received PC completed advance statements and life‐sustaining treatment documents. Patients who received PC had lower rates of aggressive EOL care, including chemotherapy and intensive care unit admission, than those who did not receive PC. Notably, PC reduced the number of blood transfusions.ConclusionTertiary PC aims to reduce aggressive EOL care through patient‐centered goal‐of‐care discussions. Therefore, there is an imperative need for concerted efforts toward seamless integration of PC.
