My colleague, Michael Cannon, makes several good points about comparative effectiveness research (CER), both in his letter to USA Today and in his excellent paper on the subject. I strongly agree with him that we should not reflexively oppose CER—much of health care spending is wasteful or unnecessary, and it makes sense, therefore, to test and develop information on the effectiveness of various treatments and technology, giving consumers tools to evaluate the value of the care they receive. There is also a case for the use of CER in taxpayer‐funded programs like Medicare and Medicaid. Taxpayers should not have to subsidize health care that has not proven effective, nor can Medicare and Medicaid pay for every possible treatment regardless of cost‐effectiveness.
However, I am more skeptical in general about CER than he is for several reasons.
- First, “quality” and “value” are not unidimensional terms. In fact, such concepts are highly idiosyncratic with every individual having different ideas of what “quality” and “value” means to them, based on such things as a person’s pain tolerance, lifestyle, feeling about hospitalization, desire to return to work, and so forth. For example, a surgeon may tell you that the only way to ensure a cure for prostate cancer is a radical prostectomy. But that procedure’s side‐effects can severely impact quality of life — so some people prefer a procedure with a lower survival rate, but fewer side effects. Who is better suited to determine which of those procedures represents “quality” and “value,” a government board or the person directly affected?
- Second, comparative effectiveness research too often has a tendency to gear its results toward the “average” patient. But many patients are outliers, whose response to any particular treatment, for either good or ill, can vary significantly from the average. This matters little when the research is simply informative. However, if the research becomes the basis for more prescriptive requirements, for example prohibiting reimbursements for some types of treatment, the impact on patient outliers could be severe.
- Third, comparative effectiveness research can create a time lag for the introduction of new technologies, drugs, and procedures. The FDA, for example, has already caused delays in introducing drugs that have resulted in unnecessary deaths. Depending on how the final program is structured, comparative effectiveness research could create another layer of bureaucracy and testing between the development of a new drug, for example, and its introduction into the health care system. One only has to look at the difficulty in expanding Medicaid drug formularies to see how this could become a problem.
The advocates of government‐sponsored CER clearly intend for it to be used as a basis for rationing care, not just in government programs, but for private insurance as well.
Cannon points out that government‐sponsored CER is likely to be corrupted under pressure from special interest lobbies and politicians. I couldn’t agree more. Government‐sponsored CER, therefore, is liable to yield the worst of all possible worlds, not only rationing, but rationing that is based on special interest lobbying rather than science.
Health care, is of course, a finite good. Therefore, it will always be rationed in some fashion. But, it is far better if the rationing agent is the consumer himself, rather than the government or any other arbitrary agent. The private sector is already undertaking CER. To the degree that consumers, insurers, and providers make use of this information, that is a good thing. If consumers don’t like how an insurance company, for example, uses CER in determining its reimbursement policy, he or she can choose a different insurer.
Government‐imposed fiat rationing allows for no such choice. Therefore, we should oppose any government involvement in CER, and any efforts by the government to use CER to restrict reimbursement, especially in private insurance plans.
