Measuring outcomes in randomized prospective trials in palliative care.

Palliative care aims to improve the quality of life of patients and their families and reduce suffering from life-threatening illness. In assessing palliative care efficacy, researchers must consider a broad range of potential outcomes, including those experienced by the patient's family/caregivers, clinicians, and the health care system. The purpose of this article is to summarize the discussions and recommendations of an Outcomes Working Group convened to advance the palliative care research agenda, particularly in the context of randomized controlled trials.
