Late decisions about treatment limitation in patients with cancer: empirical analysis of end-of-life practices in a haematology and oncology unit at a German university hospital.

Background: Decisions to limit treatment (DLTs) are important to protect patients from overtreatment but constitute one of the most ethically challenging situations in oncology practice. In the Ethics Policy for Advance Care Planning and Limiting Treatment study (EPAL), we examined how often DLT preceded a patient's death and how early they were determined before (T1) and after (T2) the implementation of an intrainstitutional ethics policy on DLT.

Methods: This prospective quantitative study recruited 1.134 patients with haematological/oncological neoplasia in a period of 2×6 months at the University Hospital of Munich, Germany. Information on admissions, discharges, diagnosis, age, DLT, date and place of death, and time span between the initial determination of a DLT and the death of a patient was recorded using a standardised form.

Results: Overall, for 21% (n=236) of the 1.134 patients, a DLT was made. After implementation of the policy, the proportion decreased (26% T1/16% T2). However, the decisions were more comprehensive, including more often the combination of 'Do not resuscitate' and 'no intense care unit' (44% T1/64% T2). The median time between the determination of a DLT and the patient's death was similarly short with 6 days at a regular ward (each T1/T2) and 10.5/9 (T1/T2) days at a palliative care unit. For patients with solid tumours, the DLTs were made earlier at both regular and palliative care units than for the deceased with haematological neoplasia.

Conclusion: Our results show that an ethics policy on DLT could sensitise for treatment limitations in terms of frequency and extension but had no significant impact on timing of DLT. Since patients with haematological malignancies tend to undergo intensive therapy more often during their last days than patients with solid tumours, special attention needs to be paid to this group. To support timely discussions, we recommend the concept of advance care planning.
