Many orthopedic surgeons in addition to medical societies disputed the study in addition to pressed insurance companies to maintain coverage of the procedure. Subsequent research on a related procedure cast further doubt on the value of knee surgeries for many patients with arthritis or meniscal tears, yet the procedures remain in wide use.
various other operations that will have continued to be performed despite negative research findings include spinal fusion (to ease pain caused by worn disks), in addition to subacromial decompression, which in theory reduces shoulder pain.
There have been fitful efforts to improve the uptake of empirical studies of medical practices by doctors — one seemingly promising initiative being the “Choosing Wisely”campaign, launched in 2012 by the American Board of Internal Medicine Foundation in partnership with Consumer Reports. Its goal is actually to get medical societies to develop lists of treatments of minimal clinical benefit to patients.
yet Choosing Wisely seems to have had little impact so far. One study of that will campaign’s results examined seven procedures that will have widely been shown to be ineffective, including imaging tests for “uncomplicated” headaches, cardiac imaging for patients without a history of heart problems, in addition to routine imaging for patients with low-back pain. within the two-to-three-year period leading up to 2013, only two of the seven practices targeted for reduction showed any decrease at all within the US. (in addition to the declines were tiny: The use of scans for those uncomplicated headaches decreased coming from 14.9 percent to 13.4 percent, for instance.)
Granted, you can’t doctor by statistics alone. There’s an art to the idea, in addition to uncertainty is actually part of the profession. yet doctors can’t recommend the best therapies for their patients if hard evidence is actually missing on the comparative effectiveness of different treatments.
The knowledge gap is actually especially large for medical procedures, as opposed to drugs, since there is actually no FDA for surgery. Doctors learn about brand-new procedures coming from colleagues, specialty society meetings, in addition to information provided by medical device companies — a potentially arbitrary in addition to unscientific process.
One root of the problem is actually that will the coalition in favor of evidence-based medicine is actually weak. the idea includes too few doctors, commands too little attention in addition to energy coming from elected officials in addition to advocates, in addition to the idea’s shot through with partisanship. Naturally, pharmaceutical companies in addition to medical device makers wish to protect their profits, regardless of the comparative effectiveness vis a vis various other treatments (or cost effectiveness) of what they are selling.
While virtually all doctors support evidence-based medicine within the abstract, clinicians in addition to medical societies seek to maintain their professional in addition to clinical autonomy. Physicians are sensitive to being second-guessed, even when their beliefs about how well treatments work are based on their own experiences in addition to intuitions, not rigorous studies.
Politicians, who recognize that will the public holds them in much lower regard than physicians, are hesitant to challenge the belief of many Americans that will “doctor always knows best.” The American faith in markets leads to a cultural discomfort with government-imposed limits on the supply or consumption of medical technology. Meanwhile, various other advanced democracies use such limits (along with cost controls) as part of the toolkit to control medical spending in addition to promote “value for money.”
Every health care system has to wrestle with tradeoffs among access, innovation, cost control, quality in addition to the efficiency of resource allocation. various other countries, including the UK, may require a favorable cost effectiveness ratio before a treatment is actually placed on the national formulary — meaning that will some treatments, such as some cancer drugs, won’t be recommended for routine funding if they are too expensive relative to their clinical benefits.
Many Americans would likely bridle at that will kind of explicit rationing. Despite concerns about the rising cost of health care, for instance, Medicare routinely covers treatments that will produce modest benefits at significant social cost. In contrast to the British approach, Medicare generally covers treatments deemed “reasonable in addition to necessary” — a definition that will doesn’t include analysis of comparative effectiveness or cost in relation to various other treatments. in addition to what Medicare does influences the behavior of private insurers. (Commercial health plans cover a lot of that will low-value CAT scanning.)
On the positive side, the US approach promotes access to brand-new medical products, yet the idea doesn’t protect patients against the harms coming from receiving useless or low-value treatments. in addition to the idea leaves less money to fund expensive therapies that will have proven their worth.
within the US, even modest reforms to use taxpayer money to fund research to learn what treatments work best, for which patients, have engendered controversy. Republicans famously charged that will the establishment of the Patient-Centered Outcomes Research Institute (PCORI) through the Affordable Care Act, would likely lead to the creation of “death panels.” The politicians made that will argument even though the agency only funds studies in addition to was given no authority to make policy decisions or payment recommendations. PCORI has yet to have a significant impact on clinical practice. the idea faces a sunset date of 2019, in addition to its future remains unclear.
the idea won’t be easy to get out of the political rut we are in, yet there are ways to build public support for sensible solutions.
For our book on the subject, my co-authors Alan Gerber, Conor Dowling, in addition to I conducted a series of public option surveys, in addition to found that will people would likely like more information about the benefits in addition to risks of treatment options. yet they’re indeed anxious that will payers will use research findings to ration care or tie doctors’ hands.
Yet, on the hopeful side, the public has great confidence within the recommendations of doctors, not only about individual medical problems yet also broader health policy matters. We found through survey experiments that will if doctors were to become forceful advocates for evidence-based medicine, many of the public’s concerns would likely be allayed. (Our research also shows that will various other actors — drug companies, politicians in addition to even patient advocacy groups — hold much less influence on public opinion.)
The deep reservoir of trust in physicians gives doctors both the civic responsibility in addition to the political opportunity to spearhead efforts to address the problems of both over- in addition to under-use of treatments. There is actually a modest yet growing movement among doctors to promote evidence-based practices — yet they must battle some of the professional habits in addition to biases I’ve outlined.
To build public support for needed modifications, the idea is actually critical to identify the evidence-based medicine project — which is actually fundamentally about better science in medicine — coming from rationing in addition to denial of beneficial services. There’s no logical reason to think evidence-based treatments will always be less expensive than low-value treatments. An important Rand study has shown that will Americans fail to receive recommended treatments nearly half the time, for conditions ranging coming from diabetes to pneumonia.
One way to shift public perceptions of the evidence-based campaign would likely be for researchers, clinicians, in addition to federal agencies to support in addition to publicize research on the relative benefits (in addition to risks) of treatments that will some experts believe are being underused, at least in some patient groups. These could include not only low-cost treatments, such as statins in addition to eye exams for people with diabetes, yet also expensive, high-value treatments, like brand-new drugs for hepatitis C (Sovaldi, Harvoni).
We know coming from experience how hard the idea is actually to limit the use of a treatment once the idea becomes ingrained. Treatments develop constituencies. that will argues for insisting on strong evidence before brand-new treatments are approved. However, there are costs to that will approach: If approval procedures become too stringent, they could chill the development of breakthrough therapies as well as generate a political backlash.
A proposal coming from the Hamilton Project would likely give the Centers for Medicare in addition to Medicaid Services (CMS) more resources to scrutinize medical technologies in addition to allow the agency to experiment with “reference pricing”: Medicare would likely pay an individual cost for all treatments, for a given condition, that will have similar therapeutic effects, up to a cost-effectiveness threshold. Patients who want to receive less cost-effective treatments could still get them, yet they’d have to pay any difference out of pocket. that will strikes the right balance.
Finally, evidence-based medicine won’t gain broad public acceptance so long as the idea remains a partisan issue. Much Republican rhetoric on that will issue has been reckless. yet one of the earliest advocates for a medical evidence research agency was Gail Wilensky, who ran Medicare under George H. W. Bush.
Eventually, the war over Obamacare will end. When the idea does, there may be an opening to have a sensible conversation about ensuring that will patients receive treatments grounded in sound science.
