Guidelines: Guides to Profit?By John Fauber, Milwaukee Journal Sentinel/Medpage Today and Ellen Gabler, Milwaukee Journal SentinelPublished: December 19, 2012The stated intent of treatment guidelines is to "guide" clinicians' treatment of patients with a series of recommendations based on evidence.But that intent may not be universally reflected in published guidelines and the disconnect is all about money.Money TalksDoctors with financial ties to drug companies have heavily influenced treatment guidelines, an analysis by the Milwaukee Journal Sentinel and MedPage Today has found.Critics say those financial relationships have corrupted the guideline process so that the end products, make dangerous or ineffective recommendations.Industry and some doctors counter that those with conflicts are often top experts in their field.The Journal Sentinel/MedPage Today examined 20 clinical practice guidelines for conditions treated by the 25 top-selling drugs in the U.S.Search top-selling drugs, guidelines and doctor conflicts on JSOnline.comThese drugs sit in the medicine cabinets of millions of Americans -- Nexium (esomeprazole magnesium) for acid reflux, Lipitor (atorvastatin) for high cholesterol, Cymbalta (duloxetine) for depression, and OxyContin (oxycodone) for pain. Their collective sales topped $94 billion in 2011, accounting for 30% of drug revenue in the U.S.An analysis of the guideline panels, which involved 293 doctors, found: Nine guidelines were written by panels where more than 80% of doctors had financial ties to drug companies. Four panels did not require members to disclose any conflicts of interest. Of the 16 guideline committees that required disclosure, two-thirds of the panel members had ties to drug companies.Some guidelines written by conflicted panels recommend drugs that have not been scientifically proven to safely treat conditions, leading to inappropriate or over prescribing, specifically guidelines for anemia, chronic pain, and asthma.In this analysis, research funded by drug companies was not counted as a conflict in the Journal Sentinel/MedPage Today analysis because there is disagreement about whether research funding poses as much of a conflict as speaking, consulting and advising.The findings offer the latest glimpse into how pharmaceutical companies, with billions in sales at stake, exert a powerful but often unrecognized influence over the practice of American medicine.Past Journal Sentinel/MedPage Today reports have revealed articles in medical journals that were ghostwritten by drug company marketers; instructional videos for doctors that made misleading claims about drugs; payments to medical organizations that advocated for more use of drugs; and drug companies paying for continuing medical education courses that, in essence, market their products."At the end of the day, the drug companies own medicine," said Eric Campbell, PhD an associate professor at Harvard Medical School who has researched conflicts of interest in treatment guidelines. "We've created a system that allows this."In March 2011, the Institute of Medicine issued a report that said fewer than 50% of members of a guideline-writing committee should have financial relationships with drug companies. No committee chairman should have a financial conflict of interest, the IOM said.In this Journal Sentinel/MedPage Today analysis just two guideline committees met the IOM criteria. Of the 16 panels that disclosed conflicts of interest, at least 10 had chairmen with financial ties to drugLa Doudoune Courte Mme companies. Payment amounts were not disclosed in the guidelines, which were issued between 2001 and 2012.Some medical societies have agreed to adopt the IOM recommendation, but many others complain the IOM set the bar too high, making it is too difficult, costly and contentious for societies, said Sheldon Greenfield, MD, chairman of the group that issued the report titled, "Clinical Practice Guidelines We Can Trust.""By and large, most of the societies have ignored it," said Greenfield, a professor of medicine and executive co-director of the Health Policy Research Institute at University of California, Irvine.Extensive time, research and expertise are poured into developing most guidelines, a process that can take years. The documents are complicated, dense and extremely technical.At their best, rigorously-developed, unbiased guidelines can help synthesize new research and improve the quality of treatment that patients receive.Even critics who want to minimize or eliminate conflicts acknowledge that guidelines written by doctors with financial ties to drug companies can offer solid, scientifically-backed recommendations.But protecting the integrity of clinical guidelines is essential to the practice of medicine, said Steven Nissen, MD, chairman of cardiovascular medicine at the Cleveland Clinic."If those guidelines are produced in a way that is not completely free of bias, then we are guiding physicians and patients toward therapies based on opinions that may have been influenced by peoples' financial relationships," Nissen said. "That is a huge problem."Some doctors and pharmaceutical industry representatives say physicians who consult for drug companies are among the most well-informed experts in their field and should help write guidelines.Experienced doctors are trained to evaluate and base their decisions on complicated medical and scientific information, without being influenced by their ties with drug companies, said Marjorie Powell, senior assistant general counsel for PhRMA, a trade group that represents drug and biotechnology companies doing research to develop new medicine.Other doctors and researchers say there are countless experts to call upon who do not have relationships with drug companies.In fact, doctors are often willing to cut ties with drug companies in order to sit on guideline writing panels, said Daniel Ouellette, MD, vice chairman of the guidelines oversight committee for the American College of Chest Physicians and a senior staff physician at Henry Ford Hospital in Detroit.Ouellette said he looks at excluding potential bias as part of the scientific process."We would rather have our panel be completely nonconflicted," he said.People with industry ties may be allowed to give insight if their expertise is so unique no one else can provide it, Ouellette said. But they can only add comments and participate in discussions, not vote on or draft guidelines.First, Do No Harm?In some cases, guideline panels have recommended treatments that have not been proven to make a meaningful difference -- or that could even harm patients.Guidelines written by conflicted panels have encouraged prescribing highly addictive narcotic painkillers to treat long-term chronic pain -- an area where the safety and effectiveness of the drugs remain unproven.OxyContin, a popular and addictive opioid, was the 19th best-selling drug in the United States last year, with $2.9 billion in sales. In 2009, the American Pain Society and the American Academy of Pain Medicine issued a guideline endorsing opioids to treat chronic pain. The guideline was written by a panel where 14 of 21 members had ties to drug companies.Also in 2009 the American Geriatrics Society advocated for greater opioid use to treat chronic pain in seniors. That guideline recommended that over-the-counter pain relievers, such as ibuprofen and naproxen, be used rarely and that doctors instead consider opioids for all patients with moderate to severe pain.Panel members said they relied on research and their own experience in revising the guidelines, acknowledging "existing weak scientific evidence." Half the experts on the panel had financial ties to opioid companies.Health and regulatory officials have declared misuse of opioids a national epidemic, citing skyrocketing addiction to painkillers and a tripling of fatal overdoses in the past decade. Emergency room departments across the country are adopting policies to discourage doctors from prescribing narcotics to patients with chronic pain and advocates are asking the Food and Drug Administration to restrict companies' marketing of the drugs.Asthma drug Advair was the nation's fifth-best selling drug in 2011, with $4.6 billion in sales. It is part of a class of drugs recommended in a 2007 guideline from the National Heart, Lung and Blood Institute.Twelve of the 18 members of the guideline's panel had financial ties to GlaxoSmithKline, which makes Advair. Three other panel members had ties to other companies that market thatDoudoune Moncler Femme Fox Collar same of class of drugs, known as beta-agonists. In all, 83% of the panel had conflicts. Beta-agonists have been linked to higher rates of death and severe asthma attacks.In recent years, medical studies, independent doctors and court records have declared that Advair has been massively overused and inappropriately prescribed.EPO= ExpensiveAn anemia drug, once the most expensive drug in the Medicare formulary, was recommended in guidelines issued in 2006 by the National Kidney Foundation.The guidelines provided recommendations for treating anemia in chronic kidney disease patients and endorsed a class of drugs including Epogen. The drug helps raise levels of hemoglobin, a protein in red blood cells that carries oxygen. Epogen is marketed by Amgen and had 2011 sales of $2.8 billion.On almost every level, the drug company was financially linked to the guideline process.Fifteen of 18 panel members who wrote the guideline for the Kidney Foundation had financial ties to drug companies. Those relationships included advising, consulting, speaking and research or unspecified contracts. Ten of those members, including both co-chairs, had financial relationships directly with Amgen.Amgen paid $1.7 million in 2004 and 2005 to fund the guidelines for the Kidney Foundation. All told, foundation records show the group received $8.7 million from Amgen in those years.Ashleigh Koss, a spokeswoman for Amgen, declined to comment for this article.Concerns about the safety of Epogen and drugs in its class have grown steadily over the past 10 years. Such drugs can increase blood clots and the risk of heart attack, stroke, heart failure and death.The Kidney Foundation's guideline recommended higher hemoglobin targets than those approved by the FDA, said Daniel Coyne, MD, nephrologist and professor of medicine at Washington University in St. Louis.To reach higher targets could require higher doses of Epogen and similar drugs, which could be harmful to patients, he said.In 2007, Coyne wrote a paper in a kidney disease journal that was highly critical of the guideline and conflicts of interest.At the time, he was an adviser, speaker and consultant for Amgen and Roche. He said he no longer does that kind of consulting work. In 2011, the FDA warned doctors to be more conservative in dosing of drugs such as Epogen because data showed higher risk of cardiovascular problems and death in kidney disease patients.The Kidney Foundation said Coyne's claim that the guideline raised the hemoglobin target is "a fundamental misinterpretation of the guideline." Foundation spokesman Sean Roach said there were subtleties to interpreting the guideline and FDA recommendations.The foundation said drug companies that provide funding for the guidelines do not influence them and that a separate team of physicians without conflicts gathers evidence for the group writing guidelines.Surrogate vs. Outcome In 2006, the American Diabetes Association and the European Association for the Study of Diabetes issued recommendations for managing high blood sugar in people with type 2 diabetes.The recommendation included use of drugs known as glitazones. At the time, the two most popular glitazones were Avandia (rosiglitazone) and Actos (pioglitazone).Both drugs were approved by the FDA in 1999 on the basis that they improved short-term blood sugar control -- not because they reduced heart attacks and strokes.Six of seven panel members had worked as speakers or advisors to drug companies, including three who worked for GlaxoSmithKline, maker of Avandia, and one who worked for Takeda, maker of Actos.Less than a year after the guideline came out, Avandia was linked to substantially increased risk of heart attacks. In 2010 the drug was banned in Europe and severely restricted in the U.S.Actos has not been shown to increase heart attacks, though the drug has been linked to increased risk of heart failure. U.S. sales for Actos have remained over $3 billion a year in recent years.David Nathan, MD, chairman of the 2006 diabetes guideline panel, said members did not have data showing Avandia was dangerous and as soon as that information came to light, the panel changed its recommendation.Nathan, a professor of medicine at Harvard Medical School, was the only panel member who did not work as a speaker or adviser to drug companies. (He has received research grants from drug companies, according his disclosure in the guideline.)Nathan said if people with conflicts of interest were eliminated from guideline panels, "we wouldn't be able to put together committees with enough expertise to make them worthwhile."In an email, Nathan acknowledged that, at the time, there was no rigorous evidence showing that either Avandia or Actos reduced the risk of cardiovascular disease, blindness or kidney damage. He said there is no compelling data that any diabetes drug reduces cardiovascular risk.Research has shown that improving blood sugar generally lowers the risk of microvascular events such as blindness and kidney damage. It was on that basis that the panel recommended the drugs, he said.A statement provided by the ADA said its policies on guidelines have been evolving and "were radically revised" after the 2011 report by the Institute of Medicine."We currently are striving to meet all of the IOM requirements, but recognize that older efforts may not have lived up to that new more rigorous standard," the statement said.In 2011, the ADA received $15 million in funding from drug and medical device companies, including $145,325 from GlaxoSmithKline and $638,250 from Takeda, according to its revenue statement. The association would not provide drug company funding amounts from the years prior to the 2006 guideline.The guideline panel's recommendation is an example of an ongoing problem in medicine, especially in diabetes care, said John Yudkin, MD, an emeritus professor of medicine at University College London.Panelists may make recommendations to use certain drugs based on a "surrogate measure," such as improving blood glucose levels, and then assuming this also reduces the risk of heart disease, kidney damage or blindness.But an improvement in a blood measure doesn't always mean a patient is facing less risk of serious health problems. Avandia and Actos never have been proven to reduce kidney damage, amputations, blindness, heart attacks or strokes, Yudkin noted.Psychiatrists Limit Conflicts After ControversyIncreased political scrutiny of drug companies over the past few years has led to more transparency, including the Physician Payment Sunshine Act (PPSA), which will require drug, device and medical supply companies to disclose any payments made to doctors or teaching hospitals. The first reports are due next spring.But reformers say that merely disclosing a conflict does not eliminate it.Four guidelines examined by the Journal Sentinel/MedPage Today did not disclose members' conflicts with drug companies. Those guidelines were issued between 2001 and 2005.The American Psychiatric Association issued one of the guidelines in 2004 for treating schizophrenia.A few years later, the group was embroiled in controversy when it decided to disclose conflicts of interest for a different guideline on depression. That panel included six of seven panel members who had worked as consultants, advisors or speakers for drug companies.Before the guideline was released in 2010 the association had an independent panel with no drug company ties review the recommendations. No bias was found, said Joel Yager, MD, chairman of the group's steering committee on practice guidelines and a professor of psychiatry at the University of Colorado.Even so, the APA no longer allows any doctors with conflicts of interest to sit on its guideline writing panels. It aims to achieve "no possibility of industry bias," Yager said."You have to play by the rules," he said.How the story was done:Reporters obtained a list of the 25-top-selling prescription drugs in the United States in 2011 from IMS Health, a market research firm.The Journal Sentinel identified the year each drug was approved by the U.S. Food and Drug Administration and the condition for which the drug was first approved.Reporters searched for relevant clinical practice guidelines using the National Guideline Clearinghouse, PubMed and other medical databases. PDoudoune Moncler Enfantreference was given to guidelines and updates issued by major health organizations and associations that were issued after 2000. When multiple panels issued guidelines, preference was given to those that disclosed conflicts of interest.Guidelines also were checked to see if specific drugs were mentioned or recommended as treatment options.Reporters identified the number of guideline panel members who disclosed conflicts of interest in the guideline. A conflict included consulting, speaking, advisory work by panel members that was paid for by a drug company, any contract with a drug company, or owning stock in a drug company. Institutional research grants and funding from drug companies were not counted because experts disagree whether research poses as much of a conflict as speaking, consulting and advising.
