Comparative Effectiveness: Research Ethics in the News

A recent article in JAMA shows a lack of current comparative effectiveness (CE) research: Michael Hochman; Danny McCormick. Hochman M, McCormick D. Characteristics of published comparative effectiveness studies of medications. JAMA. 2010 Mar 10;303(10):951-8. PubMed PMID: 20215609. In six, leading medical journals, Hochman and McCormick indentified 104 studies (32% of research articles published over 16 months) that compared the effectiveness of two or more clinical interventions. With the recent public interest in encouraging CE research and CE data-driven policy, the authors believe 32% is inadequate. They write:

The fact that only 32% of the studies in these journals evaluating medications met our criteria for CE research supports previous concerns that only limited clinical research is currently devoted to helping physicians use existing therapies more effectively.

Hoping for an increase in CE research, the authors conclude that increased public funding and new regulatory action will be needed to overcome barriers to future comparative studies:

[O]ur findings suggest government and noncommercial support should be increased for studies involving nonpharmacologic therapies, for studies comparing different therapeutic strategies, and for studies focusing on the comparative safety and cost of different therapies. In addition, our findings highlight the need for regulatory agencies like the FDA to require active-comparator trials for medication approval whenever feasible.

In an accompanying editorial, Conway and Clancy, indentify a number of next steps, including:

– a vetted inventory of CE research “so clinicians and patients can locate summaries of evidence and studies of interest;”
– attention to the best methods and appropriate resources for disseminating CE research information
– longitudinal assessments of CE research driven medicine in patient-centered care.

Readers looking for a quick overview of CE research and its implications in for the future of health policy and medical care can find a brief, new assessment from The Urban Institute. Elizabeth Docteur and Robert A. Berenson recently wrote: How Will Comparative Effectiveness Research Affect the Quality of Health Care? [PDF – 337 KB] The report provides a brief overview of the history of CE, describes the current debate and calls for:

– continued attention to the barriers, fears and concerns to CE research
– a plan for the dissemination of CE research that will “ensure practical implementation of findings”
– the complete integration of CE and evidence-based medicine in health care financing and delivery.

For a nuts-and-bolts account of the challenging task of translating CE research into better medical practice, see February’s “A Simple Health-Care Fix Fizzles Out” by Keith J. Winstein, in The Wall Street Journal (WSJ, Feb 11, 2010). Winstein uses the “Courage” trial as a case study; see: Boden WE, et al. Optimal medical therapy with or without PCI for stable coronary disease. N Engl J Med. 2007 Apr 12;356(15):1503-16. PubMed PMID: 17387127. This study found that a common procedure, implanting stents in clogged arteries, “yields no additional benefit when used with a cocktail of generic drugs.” Following the publication of the study, the use of stent implants declined by 13% in the U.S., but only briefly. Stent use in cardiology is now back to “peak levels.” William Boden, an author of the Courage trial, explains: “Most [cardiologists] haven’t voluntarily incorporated the Courage criteria into their practice …. What’s going to continue to drive practice is reimbursement.”
