Evidence-based medicine being corrupted

Dr. Weeks’ Comment: Science is nothing but a methodology. Scientific process can be honestly worked or biased and corrupted.  Here is a scathing report on how seemingly scientific evidence-based medicine can be bought and sold.  What a shame that this happens. Alas for mankind, so easily bought off.  As Oscar Wilde wrote: “I can resist anything but temptation.”

Today’s “evidence-based medicine” may be tomorrow’s malpractice

Evidence-based guidelines won’t prevent malpractice claims

Germs and the Pseudoscience of Quality Improvement


We hold these truths to be self-evident:

A hospital administrator with a clipboard is in search of a physician who isn’t following “evidence-based guidelines”.

There are fads in medicine just as there are in fashion””today’s “evidence-based medicine” may be tomorrow’s malpractice.

Did your hospital, like so many, abruptly switch from povidone-iodine antiseptic solution to ChloraPrep® for cleaning a patient’s skin before surgery?  If so, I’m sure the staff was told that ChloraPrep would be more effective and cheaper.  No doubt, they were also warned of the extra precautions that must be taken with ChloraPrep to prevent operating room fires, since ChloraPrep contains highly flammable 70% isopropyl alcohol in addition to chlorhexidine.  Even the fire risk apparently wasn’t enough to make hospitals think twice before switching antiseptics.

You (and your hospital’s staff) may not have heard this news. The US Department of Justice (DOJ) announced last month that CareFusion Corp. would pay the government a $40.1 million settlement to resolve allegations that the company violated the False Claims Act by paying kickbacks to boost sales of ChloraPrep and promoting it for uses that aren’t FDA-approved.

Who received kickbacks?  According to the DOJ’s press release, the complaint alleged that “CareFusion paid $11.6 million in kickbacks to Dr. Charles Denham while Denham served as the co-chair of the Safe Practices Committee at the National Quality Forum, a non-profit organization that reviews, endorses, and recommends standardized health care performance measures and practices.”  Another physician with close ties to CareFusion, Dr. Rabih Darouiche, was the lead investigator on a 2010 NEJM article which concluded (not surprisingly) that Chloraprep was “significantly more protective” than povidone-iodine against surgical site infections.

The Leapfrog Group, launched by the Business Roundtable in 2000, claims that its hospital survey is “the gold standard for comparing hospitals’ performance on the national standards of safety, quality, and efficiency.”  On January 30, Leapfrog announced that it accepted the resignation of Dr. Denham, who had served as chair of Leapfrog’s Safe Practices Committee since 2006, amid concerns that Dr. Denham had failed to reveal his “potentially compromising relationship with CareFusion.” At the same time, Leapfrog said it would undertake “a thorough scientific review of its full slate of endorsed safe practices.”

Are you still feeling good about evidenced-based medicine?

Then you haven’t looked closely enough at another quality measure your hospital may track:  the use of beta-blockers, a type of blood pressure medicine, around the time that patients undergo surgery.  The Surgical Care Improvement Project (SCIP) has defined beta-blocker use as a “core measure” of hospital quality, stating that a patient who has been taking a beta-blocker prior to arrival for surgery must receive a beta-blocker while in the hospital.  The medication must be taken, SCIP says, either the day before or the day of surgery, and on either postoperative day 1 or 2.

Is there a controlled study that demonstrates conclusively that the SCIP beta-blocker measure makes surgical patients healthier?  Or that they recover better from surgery?  No, there isn’t.  Does the SCIP measure track whether the patient’s blood pressure or heart rate are maintained within a normal range?  No, it doesn’t.  All it says is that the patient should receive an unspecified dose of one of a number of drugs in the beta-blocker class.  A physician can be “compliant” with the SCIP measure by prescribing only a tiny dose of esmolol, a beta-blocker whose duration of effect can be measured in seconds.  You don’t have to be a cardiologist to figure out that this is ridiculous.

What’s worse is that aggressive beta-blocker use around the time of surgery may be hazardous.  A 2013 review and meta-analysis of the medical literature concluded that starting beta-blockers before surgery caused a 27% risk increase in 30-day all-cause mortality.   Beta-blockade reduced the incidence of heart attacks, but increased the incidence of strokes and dangerously low blood pressure.

The authors of the SCIP core measure cite scientific evidence to support their recommendations.  Unfortunately, much of the science has been discredited.  Dr. Don Poldermans, a prolific Dutch researcher, led the DECREASE-IV study referenced by SCIP, which is no longer considered credible. The meta-analysisconcluded that in DECREASE-IV, “the key data required to judge outcomes were missing and the adjudication committee was fabricated.”

Larry Husten of Forbes.com has been reporting the damage caused by the Poldermans research misconduct with the overwrought headline:  “Medicine or Mass Murder?  Guideline Based on Discredited Research May Have Caused 800,000 Deaths in Europe Over the Last 5 Years.”  Even if Husten exaggerates, it would be reasonable to suspend the use of the SCIP beta-blocker measure pending further review.  Good control of a patient’s blood pressure and heart rate is a doctor’s version of common sense, and another medication might be better than a beta-blocker for a specific patient’s needs.  First-class chefs don’t base their success on slavish adherence to a cookbook recipe.

Sadly, the federal government has seized on adherence to “evidence-based guidelines” as a way of demonstrating “quality” in health care.  On February 6, key lawmakers unveiled plans to replace the Medicare Sustainable Growth Rate (SGR) formula with a new “Merit-Based Incentive Payment System” for physicians.  This system will include payment bonuses or penalties based on a composite performance score.  Patients as well as physicians should be frightened at the prospect that the government’s version of guidelines for care will forcibly replace physician judgment and experience in caring for patients as individuals.

The good news about the CareFusion settlement is that we may be seeing less of Dr. Denham on the patient safety lecture circuit, playing clips of “Chasing Zero”, the video he produced with his new best friend, actor Dennis Quaid.  The bad news:  hospitals and government agencies hate to admit they’re wrong, whether it’s about ChloraPrep, beta-blockers, or any other bureaucrat’s idea of “quality” in health care.

I have personal experience with standard protocols and core measures as a result of the abdominal surgery I underwent a couple of months ago.  From the hospital’s point of view, I’m sure I met every one of the “targets” they set for me on my “care pathway”.  The only glitch is that I developed a superficial wound infection that took more than two weeks to clear up.  The hospital’s statistics won’t reflect that, because it only became apparent after I left for home. Which skin prep solution was used for my case?  You guessed it-ChloraPrep.  Next time I’ll ask for Betadine.
