Since CMS’s Center for Medicare and Medicaid Innovation launched three years ago, its staff have been frequently hailed for undertaking an ambitious research agenda.
But a New York Times story this week was eye-catching for a different reason: author Gina Kolata mostly assailed Medicare’s researchers for how they’re choosing to do that research.
“Experts say the center is now squandering a crucial opportunity,” Kolata wrote in a front-page article. “Many researchers and economists are disturbed that [CMMI] is not using randomized clinical trials, the rigorous method that is widely considered the gold standard in medical and social science research.”
But many researchers and economists that I talked to at this week’s Academy Health conference say that’s not the case at all. (And some were disturbed to learn that they were supposed to be disturbed.)
“RCTs are helpful in answering narrowly tailored questions,” Harvard’s Ashish Jha told me. “Something like—does aspirin reduce 30-day mortality rates for heart attack patients.”
“However, for many interventions, RCTs may be either not feasible or practical.”
“While RCTs may be the gold standard for testing some hypotheses, it is not necessarily the most effective or desirable model for testing all hypotheses,” agrees Piper Su, the Advisory Board’s vice president of health policy.
CMMI’s ambitious goals
On its surface, Kolata’s article is built around a reasonable conclusion: RCTs offer plenty of value in health care, and we’d benefit from more of them.
- As Jha alludes to, think of a double-blinded pharmaceutical study where half the participants randomly get a new drug and the other half get a placebo; that’s an RCT.
- The famous RAND study that found having health insurance changes patients’ behavior: An RCT.
- The ongoing Oregon Health Insurance Experiment: Also, an RCT.
And it’s fair to examine how CMMI is pursuing its research, too.
