A big team from Duke lead by Joseph Rogers has a new Paper (PAL HF) reporting the results of a RCT of palliative care in late stage Congestive Heart Failure, published today in the Journal of the American College of Cardiology. Patients who got palliative care had better quality of life, higher function and reduced anxiety and depression (with no survival difference, as hypothesized). Costs were not a primary endpoint, but will be analyzed in later work.
After the publication of a RCT of early palliative care in stage 4 lung cancer in the NEJM in August 2010 showed improved quality of life, lower costs and longer survival, there was a move to see if such findings could be replicated in other diseases. This NHLBI funded study is part of that effort.
Real world evidence is provided imperfectly, especially with respect to policy. One example from this paper. This studies’ exclusion criteria ruled out patients with anticipated heart transplant or LVAD implantation within 6 months. Arguably, these patients aren’t ready for palliative care because they are seeking such aggressive treatments, but from a policy perspective, it is arguable that they definitely need the goals of care type of discussions that are a key part of palliative care. The successful conclusion of a trial of CHF without patients on the way to heart transplant or LVAD implantation leaves an evidence hole, even as we add to the evidence base.
Should patients thinking about an LVAD or a heart transplant get palliative care? I think the answer is yes, but this trial provides no direct evidence to inform this question. So, there remains an evidence gap (as always–good studies suggest more questions than they answer). However, the health care system often doesn’t and can’t wait for such answers, and in the case of palliative care there has been a tremendous increase in its provision at Duke, and across the nation since this study was began. The process and timing of research is slow, and the answers are often muddled, while the pace of change in addressing the needs of seriously ill patients is much more rapid. When one’s interest is policy applications, even an RCT–the gold standard of research–cannot answer all of the most pressing questions.
