BACKGROUND: Although research on palliative care in hematological malignancies has increased, research examining quality of death (QOD) and quality of care (QOC) in this population remains limited. This study compared QOD and QOC between patients with hematological malignancies and those with solid tumors. METHODS: The authors conducted a secondary analysis of a nationwide mortality follow-up survey of bereaved family members in Japan (2017-2018). The study included 3575 decedents with hematological malignancies and 50,592 with solid tumors. Propensity score matching was performed to adjust for demographic and clinical characteristics. QOD and QOC were assessed using the Good Death Inventory (GDI) and the Care Evaluation Scale 2.0 (CES). Bivariate analyses compared the matched groups. RESULTS: Overall, QOD and QOC were comparable between groups. However, among the GDI subdomains, patients with hematological malignancies had slightly lower scores for "good relationships with family" (mean difference, 0.2; 95% confidence interval CI, 0.03-0.3) and "preparation for death" (mean difference, 0.2; 95% CI, 0.04-0.3). In addition, patients with hematological malignancies were less likely to die in palliative care units than those with solid tumors (mean difference, 3.9%; 95% CI, 0.4%-7.4%). CONCLUSIONS: Although overall quality measures were similar, specific QOD domains related to family relationships and preparation for death were slightly lower among patients with hematological malignancies. These findings may reflect limited opportunities for end-of-life discussions due to the unpredictable and rapidly progressive course of hematological malignancies. Enhancing communication about prognosis and goals of care and early integration of palliative care may improve end-of-life experiences.
