Associations between palliative-care consultations and end-of-life quality in cancer patients' last 6 months

Purpose Improving end-of-life (EOL) quality for terminally ill cancer patients is crucial. However, associations between hospice/palliative care and EOL quality, as perceived by patients, are underreported. We aimed to examine the impact of palliative care consultative services on the EOL quality during cancer patients' last six months. Methods In this prospective, longitudinal study, 174 cancer patients were divided into a palliative care consultative services group (n = 65) or a non palliative care consultative services group (n = 109). The impact of palliative care consultative services on EOL quality, assessed using the Quality of Dying and Death (QODD) scale at the first and last assessments within the patients' last six months, was analyzed by linear regression with generalized estimating equations, adjusting for covariates. Results Cancer patients received palliative care consultative services a median of 34.0 days before death. There were significant main effects of groups, indicating that patients receiving palliative care consultative services had better QODD total scores (beta [95% confidence interval] = 2.12 [0.32,3.93], p = .021), death preparation (3.80 [1.71,5.89], p < .001), and treatment preferences than the reference group (3.27 [0.90,5.64], p = .007). No group differences were found in other dimensions, including symptom and personal care, whole person concern, and time with family. Conclusion Palliative care consultative services significantly improved cancer patients' perceptions of death preparation, treatment preferences, and the QODD total score. Therefore, healthcare professionals should offer palliative care consultative services to cancer patients, initiate early referrals for such care, and implement effective and individualized interventions to enhance EOL quality.
