Introduction: Experimental studies have shown that palliative care team (PCT) involvement can improve quality of life (QoL) and symptom burden of patients with advanced cancer. It is unclear to what extent this effect is sustained in daily practice of hospital care. Objective: This observational study aims to investigate the effect of PCT consultation on QoL and symptom burden of hospitalized patients with advanced cancer in daily practice. Methods: After admission to 1 of 9 participating hospitals, patients with advanced cancer for whom the attending physician answered “no” to the Surprise Question were invited to complete a questionnaire, including the EORTC QLQ-C15-PAL, at 6 points in time, until 3 months after admission. Outcomes were compared between patients who received PCT consultation and patients who did not, taking into account differences in baseline characteristics. Results: A total of 164 patients consented to participate, of whom 32 received PCT consultation. Of these patients, 108 were able to complete a questionnaire at day 14, of whom 19 after receiving PCT consultation. After adjusting for baseline differences, EORTC QLQ-C15-PAL scores for pain, appetite, and emotional functioning at day 14 were more favorable for patients who received a PCT consultation. Conclusion: PCT consultation decreased patients’ symptom burden and tends to have a positive effect on QoL of hospitalized patients with advanced cancer, even if the PCT is consulted late in the patient’s disease trajectory.
