Fan AY. “Obamacare” covers fifty-four million Americans for acupuncture as Essential Healthcare Benefit. J Integr Med. 2014; 12(4): 390-393

“Obamacare” is the informal and most-used term for The Patient Protection and Affordable Care Act, also known as the Affordable Care Act (ACA), and is a United States federal statute signed into law by President Barack Obama on March 23, 2010. Together with the Health Care and Education Reconciliation Act, the ACA represents the most significant regulatory overhaul of the United States healthcare system since the passage of Medicare and Medicaid in 1965[1]. This healthcare reform has already begun, with the open enrollment for the first year of the ACA’s healthcare exchange marketplace ending on March 31, 2014. “Obamacare” was enacted with the goals of increasing the quality and affordability of health insurance, lowering the uninsured rate by expanding public and private insurance coverage, and reducing the costs of healthcare for individuals and the government[1]. The ACA introduced a number of mechanisms, such as mandates, subsidies, and insurance exchanges that are meant to increase the coverage and affordability of healthcare. The new healthcare law also requires that insurance companies guarantee coverage for all applicants that fit within new minimum standards and offer the same rates regardless of pre-existing conditions or gender to all applicants. Additional health care reforms are aimed at reducing the cost of healthcare through additional mechanisms such as increasing competition, regulations, and incentives to streamline the delivery of healthcare and move towards a quality-based rather than quantity-based system. The Congressional Budget Office predicts that improved efficiency within the healthcare system, from the new imposed regulations, will help to lower present and future deficits as well as Medicare spending[1,2].  read more at http://www.jcimjournal.com/articles/publishArticles/pdf/S2095-4964(14)60035-2.pdf

BMJ Editors Hit–and Hit Hard–Over Careless Interpretation of Acupuncture for Chronic Knee Pain Study (JAMA 10/1/2014)

Let’s start with the conclusion, lest I lose you between here and the end.

Acupuncture is more likely to provide relief for chronic knee pain due to osteoarthritisthan any other modality. Pooled studies (a meta analysis) that compared physical interventions for chronic knee pain showed the following “effect sizes:”

(Electro-) Acupuncture: ES of 0.89
Warm baths: ES 0.65
Exercise: ES 0.55

To put this in perspective, the “Minimum Clinically Important Difference” or minimally significant Effect Size, according to patients suffering from chronic knee pain, is 0.39. And the Effect Size threshold the UK’s National Institute for Health and Care Excellence (NICE) uses to determine reimbursement is 0.50.

Call them acupuncture activists. And really brainy ones.

When an Australian group published (in October 1st JAMA) an impressively large (N=282, but there were 4 groups) clinical trial of 12 weeks of acupuncture for chronic (moderate to severe) knee pain in persons 50 years and older, they concluded no difference between the sham control and actual acupuncture. Editors of the premier acupuncture journal in the world (the BMJ group’s Acupuncture In Medicine), however, cried foul. And lamented the lost opportunity to help millions of chronic knee pain suffers. There were determined to set the record straight.

Their protest and clarification letter to JAMA was summarily rejected.

But guess what? They just happen to have their own journal. (Take that, AMA.) And not one of the enumerable, embarrassing American titles. As noted above, we’re talking The British Medical Journal (Even if the quality of the studies AIM publishes sometimes causes a cringe here and there, the White and his staff are doing the best with what they have to work with.) And so AIM editor and British Medical Acupuncture Society chief Mike Cummings proceeded to publish their quibbles today for inclusion, I imagine, in the January 2015 print edition, and set about to educate folks about how to consider clinically relevant results.

For expediency’s sake, I will extract the key arguments from their brilliantly prepared letter today. Then over the next week or so I will work on paraphrasing and whittling it down.

1. BACKGROUND OF THE CLINICAL PROBLEM. Patients with OA knee pain are suffering the commonest cause of pain and disability in older people. More than half have inadequate pain relief.2 They face a choice between ineffective paracetamol, non-steroidal drugs that can harm the heart, (kidneys) and gastrointestinal tract, gels that scarcely work, physiotherapy, opioids that cause dependency and lose effectiveness, arthroscopic washouts that do nothing or surgery.3 They deserve a fuller, more considered answer to their question: “Is it worth trying acupuncture?”

2. NIFTY DESIGN OF TRIAL. The neat part of the Zelen design that Hinman et al used was that the control group, who were not given acupuncture, were not even aware that their pain scores were used in a trial of acupuncture so disappointment could not influence their scores, as was claimed for other studies. This ‘no acupuncture’ group was compared with acupuncture (manual) and with sham laser (and with real laser, which is not considered here, to keep things simple).

3. WHERE THE ANALYSIS BEGINS TO STUMBLE. The problems started with the trialists’ choice of the threshold minimum clinically important difference (MCID) to estimate sample size. They chose a value based on one chosen by six self-styled ‘expert’ physicians,4 namely a 35% fall in baseline pain score (1.8/sample mean baseline 5.1). This is equivalent to an effect size (ES) of 0.6, calculated using their assumed baseline SD of 30 (the actual SD was 21, giving a higher threshold ES of 0.86). A different figure for MCID was generated by 192 patients with OA, who registered improvement scores as well as changes in pain.5 This showed a more modest MCID, equivalent to an ES of 0.39 (shown in figure 1). The National Institute for Health and Care Excellence (NICE) did not regard any value for MCID as valid6 and chose a generic value of 0.5 (see figure 1). Hinman et al chose a high threshold and also failed to discuss the effect that alternative threshold MCID values would have on the interpretation of their findings. We also note that the MCID for any treatment should be chosen to take account of acceptability, safety and cost-effectiveness,7 which would argue for a lower threshold for acupuncture for knee pain.

4. THE OLD “BETA ERROR” BUGABOO: SHORT ON STATISTICAL POWER. Hinman et alapplied this ‘clinically important’ difference to a ‘clinically irrelevant’ comparison–acupuncture versus sham laser. Sham laser is not an available therapy. The only reason for comparing acupuncture with sham would be to estimate the effects of the needles themselves, but this is already well known from the Cochrane review8 and an individual patient data meta-analysis (figure 1).9 It is known that the effect of needles alone is small, and so is unlikely to be identifiable reliably with sample sizes of less than about 800.10 The sample size in the study by Hinman et al (n=70) clearly appears to be inadequate for the question, according to the existing evidence, and not best use of resources. The resulting ES of acupuncture against sham that was actually found by Hinman is similar to that shown by the best evidence8 (see figure 1), although the wide CI means the data can only be of any importance when they are included in a meta-analysis in the future.

5. WHO DECIDES WHAT TREATMENT EFFECT IS MEANINGFUL? Hinman et al found that, after 12 weeks, knee pain was significantly reduced by acupuncture compared with no acupuncture control, with an ES of 0.6 (data from their table 2; see figure 1). The difference did not quite meet the MCID they had postulated–although the estimated ES is the same size as the MCID–but it more than meets the MCID chosen by patients themselves (ES 0.39) and that selected by NICE (ES 0.5). In interpreting this result, the secondary outcomes should also have been brought into thoughtful consideration: there were significant differences in favour of acupuncture for six out of eight secondary outcomes (see eTable 5 in their paper) and the response rate, which is the most patient-orientated measure of success,7 was 76% in the acupuncture group compared with 32% in the no acupuncture control group.

6. TO MAKE MATTERS WORSE, THE AUSTRALIANS STUDIED THE LEAST EFFECTIVE ACUPUNCTURE TECHNIQUE. Hinman et al did not apply optimal acupuncture. Use of electroacupuncture has been shown superior to manual stimulation for knee pain in 2010.8

A couple of weeks ago, I also came across a study of “needle-less” acupuncture, also for chronic knee pain of the OA variety. Basically it involved warming the knee with these stick on cones of burning mugwort–sort of like (very carefully) burning incense around your knee cap. That too showed clinical effectiveness, although now I am prompted to dig up the original study and see if we can fit that “effect size” into our acupuncture, warm baths, exercise line-up above. Stay tuned.
