Involvement of Palliative Care in Malignant Pleural Mesothelioma Patients and Associations with Survival and End-of-Life Outcomes.

Malignant pleural mesothelioma is a rare, aggressive, and incurable cancer with a poor prognosis and high symptom burden. For these patients, little is known about the impact of palliative care consultation on outcomes such as mortality, hospital admissions, or emergency department visits. The aim of this study is to determine if referral to supportive and palliative care in patients with malignant pleural mesothelioma is associated with survival and decreased hospital admissions and emergency department visits. This is a retrospective chart review. Study participants include all malignant pleural mesothelioma patients seen at The Ottawa Hospital-an acute care tertiary center-between January 2002 and March 2019. In total, 223 patients were included in the study. The mean age at diagnosis was 72.4 years and 82.5% were male. Of the patients diagnosed between 2002 and 2010, only 11 (9.6%) were referred to palliative care. By comparison, of those diagnosed between 2011 and 2019, 49 (45.4%) were referred to palliative care. Median time from diagnosis to referral was 4.1 months. There was no significant difference in the median survival of patients referred for palliative care compared to those who did not receive palliative care (p = 0.46). We found no association between receiving palliative care and the mean number of hospital admissions (1.04 vs. 0.91) from diagnosis to death, and an increase in mean number of emergency department visits in the palliative care group (2.30 vs. 1.18). Although there was increased utilization of palliative care services, more than half of the MPM patients did not receive palliative care despite their limited survival. There was an increase in emergency department visits in the palliative care group; this may represent an increase in the symptom burden (i.e., indication bias) in those referred to palliative care.

Involvement of palliative care in patients requesting medical assistance in dying.

OBJECTIVE: To determine the level of palliative care involvement before and after medical assistance in dying (MAID) requests, and to compare the differences between those who completed MAID and those who requested but did not complete MAID. DESIGN: Retrospective chart review. SETTING: The Ottawa Hospital (TOH) in Ontario. PARTICIPANTS: Ninety-seven patients who requested MAID at TOH between February 6, 2016, and June 30, 2017. MAIN OUTCOME MEASURES: Completion of MAID. RESULTS: Eighty-four patients were included in the study. Fifty patients (59.5%) completed MAID. The most common reasons for not completing MAID were death before completion of the required assessments (47.0%), ineligibility (26.5%), and loss of capacity (14.7%). The most common diagnoses were cancer (72.6%) and neurologic disease (11.9%). The most frequent reasons for requesting MAID were physical suffering (77.4%), loss of autonomy (36.9%), and poor quality of life (27.4%). Patients who completed MAID in this study were more likely to report physical suffering as the reason for their request than those who did not complete MAID (84.0% vs 67.6%; P = .08), yet only 23.8% of all patients requesting MAID had an Edmonton Symptom Assessment Scale completed. Before MAID request, 27.4% of patients had a community palliative care physician and 59.5% had palliative care involvement in any setting. The TOH palliative care team was involved in 46.4% of patients who requested MAID. CONCLUSION: There is still inadequate provision of palliative care for those requesting MAID. Guidelines, legislation, and guidance are needed to help physicians ensure patients are aware of and understand the benefits of palliative care in end-of-life decisions. However, the involvement of palliative care with patients who completed MAID was similar to those who did not complete MAID. Multicentre studies are needed to further explore the MAID process and clarify the role of palliative care in that process.
