Invalidated Results Watch

By MARYA ZILBERBERG, MD

My friend Ivan Oransky runs a highly successful blog called Retraction Watch; if you have not yet discovered it, you should! In it he and his colleague Adam Marcus document (with shocking regularity) retractions of scientific papers. While most of the studies are from the bench setting, some are in the clinical arena. One of the questions they have raised is what should happen with citations of these retracted studies by other researchers? How do we deal with this proliferation of oftentimes fraudulent and occasionally simply mistaken data?

A more subtle but no less difficult conundrum arises when papers cited are recognized to be of poor quality, yet they are used to develop defense for one’s theses. The latest case in point comes from the paper I discussed at length yesterday, describing the success of the Keystone VAP prevention initiative. And even though I am very critical of the data, I do not mean to single out these particular researchers. In fact, because I am intimately familiar with the literature in this area, I can judge what is being cited. I have seen similar transgressions from other authors, and I am sure that they are ubiquitous. But let me be specific.

In the Methods section on page 306, the investigators lay out the rationale for their approach (bundles) by stating that the “ventilator care bundle has been an effective strategy to reduce VAP…” As supporting evidence they cite references #16-19. Well, it just so happens that these are the references that yours truly had included in her systematic review of the VAP bundle studies, and the conclusions of that review are largely summarized here. I hope that you will forgive me for citing myself again:Continue reading…

Medical Loss Ratios – Again!

• 4

By ROGER COLLIER

A new study, reported in the American Journal of Managed Care, seems likely to add more heat to the continuing medical loss ratio controversy.

The Accountable Care Act effectively mandates that health insurers achieve MLRs of 85 percent for large group business and 80 percent for small group and individual business, with insurers not meeting these thresholds required to make rebates to affected policyholders. However, the ACA allows HHS to issue a waiver if the requirement would disrupt a state’s insurance market. So far, an individual coverage waiver has been granted to the State of Maine, with eight other states’ waiver requests being considered. The study reported by AJMC examined individual coverage data from health insurer filings to state regulators, as reported to the National Association of Insurance Commissioners. For each state (except California, where most health insurers report to a state agency other than the Insurance Commissioner), the study computed the number of individuals with coverage (in terms of enrollee-years), the number of insurers offering coverage, and the medical loss ratios (recomputed to reflect differences between ACA’s definition of MLR and that used by the NAIC).

Based on this data, the study went on to estimate the number of enrollees in plans failing the ACA’s 80 percent threshold, and the number of higher-risk individuals who might have difficulty in finding coverage if their insurer exited the market. At first sight, the findings seem dramatic and very different from the expectations of the MLR provision’s Senate authors. The AJMC article estimates that in nine states (Arkansas, Illinois, Louisiana, Nebraska, New Hampshire, Oklahoma, Rhode Island, Wyoming, and West Virginia) at least half of the individual health insurers missed the 80 percent threshold in 2009, while in twelve states (Arkansas, Arizona, Florida, Illinois, Indiana, New Hampshire, Nevada, South Carolina, Tennessee, Texas, Virginia, and West Virginia) more than half of the enrollees were covered by insurers failing the standard, with some two million individuals nationally covered by such insurers. The study then projected that overall more than a hundred thousand enrollees (with more than ten thousand in each of Florida, Illinois, Texas, and Virginia) would find it difficult or impossible to find coverage if their non-MLR-compliant insurers exited the market. If the study’s findings are accurate, somewhere between a dozen and twenty states could reasonably demand waivers of the individual market MLR standard.

However, as the authors note, there were significant study limitations as well as possible source data inaccuracies. Enrollment in health plans offered by life insurers was generally omitted, as was all data from California. Additionally, the findings are dependent on state reporting to the NAIC, something that some of the data shown in the article suggests may be unreliable. For example, Maine—the only state so far granted an MLR waiver—is shown as having an average MLR well above the 80 percent threshold, while insurers in Michigan are shown as having an average MLR in excess of 1.0 in both 2002 and 2009—an unlikely consistently money-losing trend in a large state.

Why Primary Care Parity Matters

• 16

By PAUL FISCHER, MD

After an exciting and challenging day of caring for patients and teaching students, a third-year medical student on his family medicine rotation says to me, “I really like what you do, but I just cannot afford to go into family practice.”  I realized that by “afford,” he was referring not only to finances but also to the expectations of his parents, friends, and medical school. After spending 35 wonderful years as a family doctor, I have been “dissed’ by a kid who wants to become a dermatologist.

So I am of two minds.  Part of me is fulfilled by being needed, loved, and respected by my patients.

Over time, they have increasingly looked to me to diagnosis, advise, reassure, and guide them through a complex healthcare environment in which few others offer them help.  Another part of me sees that what I do is increasingly devalued by forces outside the exam room ― those who pay for health care, those who question the “medical necessity” of each test I order or drug I prescribe, and those in medicine who are more likely to know a procedure’s CPT code than a patient’s name.

We are in this position because we have failed to define ourselves, instead allowing others to perpetuate myths about what we do.  The first such myth is that what we do is easy.  Nothing can be further from the truth.  In about 15 minutes, we are asked to treat a long list of chronic problems (e.g., diabetes, obesity, hypertension), resolve a few new problems (eg cough, headache), address preventative health recommendations (eg, smoking, flu shot), integrate the psychosocial issues that  impact the patient’s health, and figure out how to get it all paid for by an insurance company using  codes that don’t really match either my patient’s problems or the care I provide.  Oh, and by the way, can you look at this rash and fill this prescription for my husband? Recent research has shown that an average primary care visit is 50% more complex than a visit to a cardiologist and five times more complex than one to a psychiatrist. So no, it is not easy.

The second myth is that it requires less training than other medical specialties.  This has resulted in some assuming that primary care can be left to “midlevel” clinicians.  While physician assistants and nurse practitioners can work effectively in primary care settings, it is a mistake to believe that they  provide equivalent care to patients with complex problems, and we have suffered by the wide acceptance of this assumption.   OR techs can work effectively in an operating room, but no one suggests that they replace surgeons.

Another Swing at the Windmill of VAP

• 1

By MARYA ZILBERBERG, MD

Sorry, folks, but I have been so swamped with work that I have been unable to produce anything cogent here. I see today as a gift day, as my plans to travel to SHEA were foiled by mother nature’s sense of humor. So, here I am trying to catch up on some reading and writing before the next big thing. To be sure, I have not been wasting time, but have completed some rather interesting analyses and ruminations, which, if I am lucky, I will be able to share with you in a few weeks.

Anyhow, I am finally taking a very close look at the much touted Keystone VAP prevention study. I have written quite a bit about VAP prevention here, and my diatribes about the value proposition of “evidence” in this area are well known and tiresome to my reader by now. Yet, I must dissect the most recent installment in this fallacy-laden field, where random chance occurrences and willful reclassifications are deemed causal of dramatic performance improvements.

So, the paper. Here is the link to the abstract, and if you subscribe to the journal, you can read the whole study. But fear not, I will describe it to you in detail.

In its design it was quite similar to the central line-associated blood stream infection prevention study published in the New England Journal in 2006, and similarly the sample frame included Keystone ICUs in Michigan. Now, recall that the reason this demonstration project happened in Michigan is because of their astronomical healthcare-associated infection (HAI) rates. Just to digress briefly, I am sure you have all heard of MRSA; but have you heard of VRSA? VRSA stands for vancomycin-resistant Staphylococcus aureus, MRSA’s even more troubling cousin, vancomycin being a drug that MRSA is susceptible to. Now, thankfully, VRSA has not yet emerged as an endemic phenomenon, but of the handful of cases of this virtually untreatable scourge that has been reported, Michigan has had plurality of them. So, you get the picture: Michigan is an outlier (and not in the desirable direction) when it comes to HAIs.Continue reading…

Accountable Care Organizations and Antitrust

• 7

By TIM GREANEY

There’s a new PSA test in health care.  Hopefully it will prove more reliable than that other one.

In conjunction with the unveiling of the long-awaited ACO regulation by HHS, the FTC and Department of Justice issued a Joint Policy Statement setting forth their standards for conducting an expedited (90-day) antitrust review of applicants for ACO certification.  The agencies explained that they will evaluate applicants’ market power based on the ACO’s share of services in each participant’s Primary Service Area (PSA) defined as the “lowest number of contiguous postal zip codes” from which the hospital or physician draws at least 75 percent of its patients for its services.   The Statement summarized the antitrust implications of ACOs formed by hospitals or physician groups with large market shares in their markets:

ACOs with high PSA shares may pose a higher risk of being anticompetitive and also may reduce quality, innovation, and choice for both Medicare and commercial patients. High PSA shares may reduce the ability of competing ACOs to form, and could allow an ACO to raise prices charged to commercial health plans above competitive levels.

The antitrust enforcers were properly concerned with the risk that ACOs could become a vehicle for increasing or entrenching provider market power.  Studies by academics, health policy experts and state governments have documented the impact of provider concentration on insurance premiums. Moreover, a post-reform merger wave may have increased the number of hospital and specialty physician markets and many areas are already served by dominant local providers.  Inasmuch as the success of the ACO concept depends on its ability to spur delivery system change, the predictable intransigence of monopolistic providers presents an important issue. In this regard, it is heartening that the extended (and apparently controversial) regulation drafting process produced a result that promises to constrain the growth and exercise of market power.Continue reading…

The ACO Rules & Privacy

• 23

By MARGALIT GUR-ARIE

One day before the first of April, HHS published the much anticipated rules defining the creation and operations of Accountable Care Organizations (ACO) spanning 429 pages of business regulation, analysis of various options available, proposed solutions and ways to measure and reward (punish) success (failure) in achieving HHS seemingly incompatible goals of providing better care for less money. I am fairly certain that health policy experts, health care economists and the multitude of industry stakeholders will be dissecting and analyzing the hefty document in great detail in the coming weeks. I started reading the document with an eye towards the ACO implications for HIT, which as expected are many, but something on page 108 made me stop in my tracks. HHS is proposing to share personally identifiable health information (PHI) contained in Medicare claims with ACO providers unless patients “opt-out”.

Beginning on page 108 and through 22 pages of tortured arguments, HHS makes the case for the legality and benefits of providing ACOs with PHI contained in Medicare claims, unless the patient actively withdraws consent for this type of transaction. The argument for the legality of claim data sharing rests on the nebulous HIPAA clause which allows disclosure of PHI for “health care operations” within a web of covered entities and business associates connecting the ACO with Medicare and other providers of health care services for a particular patient. HHS is proposing to make available four types of medical information to participating ACOs:Continue reading…

First Impressions of the Medicare ACO Rule

• 7

By VINCE KURAITIS

On March 31, CMS released the long-awaited “Medicare Shared Savings Program: Accountable Care Organizations” document (ACO Rule). Read the details here (strong suggestion: unless you’re working on your PhD in ACOs, start with the fact sheets).

There are many surprises. Here are eight first impressions on this 429 page tome:

  1. The bar has been set high…very high.  Tire kickers need not apply.
  2. Don’t expect to see many or any small ACOs.
  3. Patients will be confused by ACOs.
  4. Concerns over maintaining competition and avoiding antitrust are being taken seriously.
  5. CMS scores points for coordinating the ACO Rule across Federal agencies.
  6. CMS loses points for micromanagement and a controlling mindset.
  7. Possible losers — hospitals, ACO vendors.
  8. Possible winners — physicians, health plans.Continue reading…

Full employment for health futurists?

I’m not quite as convinced as some that there’s too much difference in the amount of consulting being requested and required by health systems now compared to in years past. After all it wasn’t so many years ago that APM made every hospital in America buy physicians one year and sell them the next. And there’s been plenty of cash poured down the drain of Meaningful Use and EMR implementation. But this WaPo article manages to quote 2 of the 3 best known health futurists (FD I know them all well!) not to mention a bunch of others, on the topic of consulting being demanded in the ramp up to ACOs. So while journo Bara Vaida got quotes from Ian Morrison & Jeff Goldsmith, I’m concerned–couldn’t she find Joe Flower’s email?

Minor League Report Cards

• 5

By DAVID DRANOVE

I was pleased to see the Chicago Tribune carry an op-ed piece this week by my friend and colleague Michael Millenson. The gist of the piece was that information about hospital quality is readily available online and we should use that information when choosing a hospital. Michael is right — there is no shortage of places to turn to get information about hospital quality. But I think he waxes too enthusiastic.

For one thing, it is not clear whether the widespread availability of quality information is a boon or a problem. Consider Medicare’s Hospital Compare website. Look up quality information for pneumonia and you are overwhelmed with nearly 20 different measures on four different web pages. I couldn’t possibly make sense of all this information even if I used sophisticated computer software; how could the average person sort through it all? One quality measure seems to stand out – mortality. But I wonder if this should be a major concern for pneumonia patients. Are we talking about 5 percent mortality rates, or 0.05 percent? I don’t know and Medicare won’t tell me.

HealthGrades.com is much simpler – it just reports mortality. The widely respected Leapfrog Group reports mortality for pneumonia and also reports another 8 general hospital quality measures, some of which are derived from even more measures.

When reading these report cards I find that my local hospital in Highland Park scores very well on mortality in the HealthGrades and Leapfrog reports but I can’t find it anywhere at the Medicare website. And I wonder if the low mortality rate is due to the hospital or due to the demographics of the patients. Michael Millenson pointed out that these report cards are risk adjusted, but he failed to mention that the available risk are pretty lousy – mostly controls for age, sex, and a few comorbidities. (Much better risk adjustment is possible but requires data not available to Medicare, HealthGrades, or Leapfrog.) Hospitals that get poor quality scores often report that their patients are sicker than the risk adjusters give them credit for. They might be right. Hospitals that get good scores never claim that their patients are healthier. Maybe they are hiding something.Continue reading…

Save Money on Medical Costs – Get Your Old Medical Records

• 23

By DAVIS LIU, MD

There are many tips to saving money on medical costs like asking your doctor only for generic medications, choosing an insurance plan with a high deductible and lower monthly premiums, going to an urgent care or retail clinic rather than the emergency room, and getting prescriptions mailed rather than go to a pharmacy.

How about getting your old medical records and having them reviewed by a primary care doctor?  It might save you from having an unnecessary test or procedure performed.

Research shows that there is tremendous variability in what doctors do.  Shannon Brownlee’s excellent book, Overtreated – Why Too Much Medicine Is Making Us Sicker and Poorer, provides great background on this as well as work done by the Dr. Jack Wennberg and colleagues on the Dartmouth Atlas. Some have argued that because of the fee for service structure, the more doctors do the more they get paid.   This drives health care costs upwards significantly.  Dr. Atul Gawande noted this phenomenon when comparing two cities in Texas, El Paso and McAllen in the June 2009 New Yorker piece.

Between 2001 and 2005, critically ill Medicare patients received almost fifty per cent more specialist visits in McAllen than in El Paso, and were two-thirds more likely to see ten or more specialists in a six-month period. In 2005 and 2006, patients in McAllen received twenty per cent more abdominal ultrasounds, thirty per cent more bone-density studies, sixty per cent more stress tests with echocardiography, two hundred per cent more nerve-conduction studies to diagnose carpal-tunnel syndrome, and five hundred and fifty per cent more urine-flow studies to diagnose prostate troubles. They received one-fifth to two-thirds more gallbladder operations, knee replacements, breast biopsies, and bladder scopes. They also received two to three times as many pacemakers, implantable defibrillators, cardiac-bypass operations, carotid endarterectomies, and coronary-artery stents. And Medicare paid for five times as many home-nurse visits. The primary cause of McAllen’s extreme costs was, very simply, the across-the-board overuse of medicine.

Doctors apparently seemed to order more tests.  Patients, not surprisingly, agreed.  After all, without adequate medical knowledge or experience, how sure would you be if a doctor recommended a test and you declined?Continue reading…
