Impact of intervention aimed at improving the integration of oncology units and local palliative care services: results of the multicentre prospective sequential MIRTO study.

Background: Chemotherapy (CT) in patients with advanced cancer (ACP) near the end of life is an increasing practice of oncology units. A closer integration with palliative care (PC) services could reduce the use of potentially harmful CT. This prospective study is aimed at assessing whether a more integrated care model could reduce CT use near the end of life and increase local PC service utilisation.

Methods: The study enrolled sequentially two cohorts of ACP with an estimated life expectancy of ≤6 months. In the first cohort, the usual oncologist's practice to prescribe CT and to activate local PC services were recorded. In cohort 2, the oncologist's decision was taken after an in-hospital consultation with the local PC teams. After patient death, a follow-back survey was carried out.

Results: The two cohorts included 109 and 125 evaluable patients, respectively. The oncologist's decision to prescribe CT occurred in 51.4% and 60%, respectively: the percentages of patients receiving the final CT administration in the last 30 days of life did not differ in the two cohorts (33.9% and 29.3%, respectively,p=0.83). Conversely, an increase in home PC service utilisation (from 56.9% to 82.4%, p=0.00), at home deaths (from 40.4% to 56.8%, p=0.01) and in-hospice deaths (from 8.3% to 19.2%, p=0.00) occurred in cohort 2.

Conclusion: The implementation of an initial in-hospital consultation of oncologists and experienced home PC teams has not reduced the use of CT near the end of life but increased PC service utilisation and reduced in-hospital deaths.
