Mammograms are less useful than you think

An essay in this month’s Health Affairs is compelling reading, at least for folks like me. In brief, the author describes the reasons why she, despite a positive family history, does not get an annual mammogram.

The following paragraphs encapsulate the argument nicely, I think:

“If 2,000 women are screened regularly for ten years, one will benefit from the screening, as she will avoid dying from breast cancer. At the same time, ten healthy women will…become cancer patients and will be treated unnecessarily. These women will have either a part of their breast or the whole breast removed, and they will often receive radiotherapy, and sometimes chemotherapy. Furthermore, about 200 healthy women will experience a false alarm. The psychological strain until one knows whether or not it was cancer, and even afterward, can be severe.”

And:

“Another important fact from my friends at the Nordic Cochrane Centre: It has not been shown that women who undergo regular screening live longer than those who don’t. This information is available elsewhere in different forms, but I like the clarity and concision of the Nordic Cochrane Centre pamphlet—as well as its list of solid scientific references.”

Both of these are from the Nordic Cochrane Center, an offshoot of the Cochrane Collaborative, probably the most respected outcomes and effectiveness research group there is. Cochrane Reviews are widely thought to be authoritative answers to the question “What is the best way to diagnose and treat/manage $DISEASE?” Note that because they’re the best evidence there is doesn’t mean it’s what’s *done*, but the evidence is available if you want to look for it. They have a recently done an analysis of breast cancer screening with mammography which I have yet to read, but which is essentially a redo of the work the USPSTF did a while back on mammography, when they scaled back their recommendations to great political uproar. They came to the same conclusion: mammography doesn’t work as well as we think it does. We aren’t good enough yet to know who should be screened and who should not, and screening may not do all the good we’ve ascribed to it.

And now the political problem. A *lot* of people have invested a *lot* of themselves, their scientific and professional careers, their volunteering lives, and their incomes, in the goal of increased and aggressive screening, early detection and treatment. Which, it turns out, may not work. But these folks have sunk a *lot* of themselves into those goals, including making those goals the focus of their work- from oncologists and surgeons who treat breast cancer patients (who basically treat people with breasts as if they all have cancer, either now or Real Soon Now), to cancer survivors who are going to be hard to convince that either they would have survived anyway, or they basically got lucky by having screening at *just* the right time, to the thousands of people who have devoted their volunteer efforts to increasing awareness and funding for breast cancer research and treatment. None of those people wants to hear they may have been wrong. That they may have spent their time fruitlessly, needlessly. Or that the work they have devoted themselves to (and make their living from) may be, not just a waste of time, but an active harm to many women who worry needlessly about having cancer, or worse, who are treated as if they have cancer when they do not.

So no one is hearing the Cochrane review, just as no one hears the one which says that surgery for back pain is wrong, or that reducing dust mites doesn’t control asthma, or that any of a number of other things we do to control or treat disease don’t work. And some politicians, quick to sense an opportunity to get in good with a large voting block (people with breasts, or who know someone with breasts), are happy to decry the review, or the USPSTF guidelines, as a ploy to reduce health benefits for vulnerable people (with breasts).

There is, really, a science of figuring out what works and what doesn’t. It’s called epidemiology, and its sister science, biostatistics. They both require really large data sets to chew on to give results anywhere near accurate, but when large data sets are available, they’re really good at pulling some wheat out of that there chaff. And it turns out that mammography may be chaff, and maybe we shouldn’t be shilling for it the way we have been.

Read the essay. It’s thoughtful, well written, and enlightening.

Uninsurance rate up as poor economy rolls back insurance levels

Writing for the Commonwealth Fund, a well respected health policy foundation, Karen Davis (one of the two important Karen’s in health policy, the other being Karen Ignani, the leader of America’s Health Insurance Plans or AHIP) noted that the number of uninsured people in the US continues to rise. This is a fairly clear result of the ongoing recession, as more people lose employer sponsored insurance, and more employers don’t offer employer sponsored insurance. Last year 7 million people lost the insurance they had through their employer. Seven million people added to the rolls of taxpayer funded health care, or left without any health care at all. Oh, sure, they can go to the Emergency Department, as former President George W. Bush famously remarked. But if they do, they’ll get a bill, and probably a bigger bill than their insurance company would have received for the same service. and definitely a bigger bill than they would have gotten for going to their own doctor-emergency departments charge a premium for being open 24/7/365, because it makes their overhead much higher.

“But wait”, you ask. “Wasn’t this part of the problem health care reform was supposed to solve?” Well, yes, it was. But the important provisions of that law, with a few exceptions, don’t take effect until 2014. Some of the provisions do take effect sooner-importantly, the provision which requires insurers to cover “minor children” up to age 26 takes effect today (September 23, 2010), as well as the elimination of lifetime coverage limits. But the major parts-the health insurance exchanges, the premium subsidies for middle-income families with children, the expanded Medicaid eligibility, and COBRA assistance for the unemployed-are still three years away. That may be too long for some folks who don’t have insurance now, but still need health care.

Here in Massachusetts we have an advantage-we’ve set those things up already, and when time comes to implement them, all we’ll really need to do is make sure they meet the Federal standards. Since Congress used the Massachusetts law as something of a template for the Affordable Care Act, most likely our exchanges will exceed the requirements quite a bit. We ought to be proud of that.

Doctors who care for poorer patients get poorer performance ratings

Doctors and health policy analysts at the Massachusetts General Hospital in Boston recently examined performance measures for physicians – this is the data from the surveys you fill out occasionally when your insurance company asks you to rate your doctor. They found that doctors who take care of poorer patients (as measured by annual income) generally receive poorer performance ratings. This is a somewhat counterintuitive finding; most physicians perceive that patients with higher incomes (and generally higher corresponding educations) are more difficult to please.

This has serious implications for the future of performance measurement. Because insurers and Medicare want to link these performance measures to physician payment, anything that affect them is going to be closely analyzed by doctors, who naturally want to maximize their pay. If taking care of poorer (but insured) patients decreases doctors pay, doctors will be less likely to take care of this class of patient. On the other hand, adjusting the formula by which performance is measured to correct this specific imbalance will be politically difficult; physicians who have few of these types of patients will feel they are being penalized for their patient mix or choice of practice location.

Unanswered in all of this is the question of why these physicians get poorer ratings. All of the physicians in the study are in the same practice group; there is no mechanism by which patients can tell which doctors take care of poorer patients (so wealthier patients are not able to tell by looking at the patients around them whether their doctor is taking care of “rich” or “poor” patients, for instance). Do patients of higher socioeconomic status simply have an easier time communicating with doctors, and hence are more satisfied with their care than less-well-off people? Inquiring minds want to know (and are probably working on it even now).

This kind of data helps to craft better performance ratings, and may also help explain some aspects of health disparities. While some aspects of your health are solely under your control, knowing why people act a certain way towards health care providers can help you control those aspects better.

The “humble” neighborhood health center.

The Great Brook Valley Neighborhood Health Center in Worcester changed names this Thursday, becoming the Edward M. Kennedy Community Health Center, a tribute to Ted Kennedy’s role in bringing Community Health Centers into being. Seems like a good time to review the history and role of a neighborhood health center.

Technically, a Federally Qualified Health Center is a community based organization which provides comprehensive primary and preventive care to a community, regardless of their ability to pay. They are generally governed by a locally based board of directors, and one of the unique features of the governance structure is that 51% (or more) of the board members must represent the population of the community (and generally receive their care there). Health care reform funding is expected to modernize existing centers, and significantly expand the network of centers nationwide.

Since health centers are a much cheaper way of providing health care, this can help save money for the health system overall, especially the parts of the system paid for by tax money. At the same time, people served at these health centers will generally be healthier, because the same research shows that the reason people who receive care at health centers have lower costs is because “providing quality primary care services can reduce the need for other ambulatory and hospital-based medical care, thereby lowering overall medical costs”.

Unfortunately, neighborhood or community health centers still carry the stigma of being places where poor people get their care-not a place you’d like to go if you had the chance to get out. People have a love/hate relationship with them-sort of like coming from a bad neighborhood that you still love, because it’s home. The stigma is in some sense justified-most of the people (70%) who get their care at neighborhood health centers are living in poverty by the federal definition. This is another way of saying, though, that they do one of the toughest jobs in health better than any other model of care delivery, for less money.

The facts suggest that we’d be served a lot better, most of us, if we got our primary care through a place which used the community health center model. Health care is almost never just about medicine, because so many other things impact your health. If your house is being foreclosed, it affects your health. If you’re having trouble handling your teenager, that affects your health. If your neighborhood is in the middle of an epidemic of flu, or norovirus, that affects your health. If your drinking is out of control, that affects your health. None of these problems are directly the responsibility of your doctor, but wouldn’t it be nice if, when you went to see her about them, she had the resources to work on the whole problem or set of problems, rather than just bandaiding over your symptoms?

That is what neighborhood health centers are designed to do; treat the whole person, in their family unit, in their community. And whatever you think of Ted Kennedy, I think that’s evidence of solid service to the nation.

Study shows more young adults have health insurance after Massachusetts health reform

The Massachusetts health reform law (often called “chapter 58”) made several special provisions for young people (defined as those between 19 and 26), because they represented a disproportionate share of the uninsured population, and were less likely to have access to insurance through work (as most of the jobs available to people in that age group don’t come with insurance). The Urban Institute recently reported a study of the impact of chapter 58 on insurance rates among young people which showed that these special provisions have worked as intended. The uninsurance rate in this group fell 60% (from 21% to 8%, in round numbers).

Achieving this goal, though, required some compromises. Young adults were largely brought into the insurance fold via “Young Adult Plans”, insurance plans with important exclusions and relatively high deductibles. In addition, many have annual maximum coverage amounts (usually around $50,000). Most young people will be fine with these restrictions, as most people in this population are healthy. These plans are similar to the “college plans” which were available before reform; unfortunately, these plans were cited in a 2009 article in the Boston Globe for having higher administrative costs, and that slightly less than 1% of covered students exceeded the $50,000 cap on benefits (951 people)(Link to complete study result). A more recent investigation by the New York attorney general reported in the Chronicle of Higher Education showed that these issues are neither limited to Massachusetts nor have they stopped due to the investigations in Massachusetts.

Regardless of the potential downsides to Young Adult Plans, they do bring important benefits. Access to primary care, in particular, is an enormous benefit (all Massachusetts plans require at least three routine primary care visits be covered). And in the spirit of beginning as we mean to go on, getting people insured in their youth may form a habit of receiving regular preventive care which can translate into benefits in later life, as well as benefits now through the screening and teaching which are big components of the primary care visit. There hasn’t yet been an analysis of the downsides, and while the statistics suggest there are few people who outrun the limitations of a young adult plan, for those who do the impact, financially and personally, can be devastating.

Palliative care helps you live longer and better at the end of life

Many of you will remember the “death panel” controversy during the health care reform debates last year. For those who don’t, a proposal to create a better payment mechanism for discussions between physicians and patients about end-of-life choices was derided by opponents of reform as funding for “death panels” which would make sure that elderly people chose the option of “dying early” to save on health care costs. Now it appears that early palliative care not only helps you be more comfortable and more in control of your health during serious illness, it can help you live longer as well.

A recently completed study from the Massachusetts General Hospital, researchers studying end of life care in a group of lung cancer patients found that the group assigned to early palliative care had higher quality of life and less depression than patients who received “standard care” (without early palliative care). Alone, this wouldn’t be a surprise; the surprise came when they found that the patients who received early palliative care lived longer, as well.

The policy implications of this finding are profound and seem to run counter to common sense. People have the idea that they can either fight disease as aggressively as possible, to live as long as possible or opt for care whose very name – palliative – seems to say that you’ve given up, and you’re just going to paper over the disease. The research from MGH is telling us that this is a false choice. Early palliative care-care which pays attention to relieving the symptoms of the disease-as well as fighting the disease through the usual means, you can live longer and feel better.

Far from demanding that we “die early”, advocates for palliative care want us to live as long as possible, but to help us keep our dignity and our humanity while we fight, and to make us ready for whatever our next step may be. Death is still inevitable; it doesn’t have to be miserable as well. We have it in our power to ease the transition, as well as delay it, and there doesn’t have to be a choice between the two. Promoting better and earlier use of palliative care is good healthcare policy choice, as well as a good use of our healthcare dollar.

On psychiatry

Some of you have heard my psychiatry rant. In short, it goes like this: Psychiatrists are not doctors, in the “physician” sense. They don’t do any of the things I recognize as “being a doctor”; they don’t examine patients or their pathologic equivalents (xrays, tissue slides, lab values-doctors do that stuff in some specialities and are still “physicians” in my book). Yes, they went to medical school, they learned all the stuff I learned, and then proceeded to enter a field where most of that knowledge is largely unnecessary.

It’s not that mental illness isn’t disease-it is, in the truest sense of the word; patients with mental illness are some of the most tormented people I’ve seen. But the discipline which cares for them is “mental health” (an umbrella term which most people use to include psychologists, social workers, various subsets of counseling and “life coaching”, etc.), not “psychiatry”. And it’s an entirely different mindset.

Recently I picked up a copy of “Unhinged”, a critique of psychiatry by Daniel Carlat, a psychiatrist in Newburyport. It’s an excellent read, I recommend it highly. But here, in a nutshell, is the issue with “psychiatry”, as per Dr. Carlat:

“It is called “medical school” for a reason. Its purpose is to teach students how to combine patient interviews, physical exams, and laboratory tools to diagnose biomedical diseases, and then to combine advice, medications and technical procedures to cure them [ed note: I would add “or control them”, but that’s a quibble] The basis for it all is an understanding of pathophysiology. But in psychiatry, we do not know the pathophysiology of mental illnesses, and therefore we do not use physical exams or laboratory data to diagnose” [emphasis mine]

He goes on to say trenchant things about why psychiatrists should not go to medical school, arguing persuasively that it’s bad for psychiatry and mental health in general (psychiatrists often try very hard to be kings of the mental health hill, because they’re doctors, you see), bad for medical school, and bad for patients. He argues for a new model of mental health professional, with a wholly revamped training program, combining the best of the various disciplines which now constitute mental health (psychology, social work, etc.)

I think it’s an intriguing idea. And like I said, an excellent book.

(And to hopefully forestall some ranting: yes, there is a neuroscience of mental illness. It isn’t ready for prime time. When I can measure your serotonin or norepinephrine, and use that to diagnose your illness or gauge your treatment response, then we’ll have another conversation. When I can do a depression scan, or a schizophrenia scan, or a bipolar scan, with some idea of exactly what I’m measuring and use that knowledge to guide treatment, reconsideration may be in order. But psychiatry *isn’t there yet*. Mental health has made *immense strides* since Freud invented the idea, and kudos to all the people working in that field both treating patients and working to advance the understanding of their disease. That work needs to keep happening. And medicine and mental health need to work together to care for *our* patients. But psychiatry has become an empty shell of a once proud profession IMO, as understanding of non-mental illness (or perhaps “less mental” illness) has advanced faster than the understanding of mental illness. What that says to me is that mental illness is a hard, complex problem, not that it’s less prestigious or not a problem)

What, exactly, counts as “health”?

The health reform law (now mostly called the Patient Protection and Affordable Care Act, or just the Affordable Care Act (ACA) requires many insurers to maintain a “medical loss ratio” of at least 85%. The medical loss ratio is the percentage of premiums which the insurer must pay out as health care. So if the premium for health insurance is $100 per month, the insurer must, on average, spend $85/month on payments for health care used by everyone insured by the company.

Naturally, health insurers are interested in maximizing the kinds of things they get to call “spending on health care”. For instance, is utilization review “spending on health care”? Generally, I would argue it is not; it is generally of little benefit to the individual person insured, but of significant benefit to the insurance company. (Utilization review is the process an insurance company uses to assess whether you still need to be in the hospital, or if you really need that MRI, or if you could manage with a less costly medication). Is there a benefit to these programs? Well, yes and no; the individual doesn’t benefit that much. The group of beneficiaries as a whole benefits some, since every dollar saved by UR is a dollar which can potentially be spent on other health care. But UR is much hated by patients and doctors, not because it is done (it’s done some useful things for length of stays, which were arguably way too long when UR started in the 80’s), but because it’s so haphazard. Everyone has their own rules, the rules are often arbitrary, or arbitrarily enforced, and the appeals process is arduous and uncertain.

The National Association of Insurance Commissioners (the group of state insurance commissioners; this is a government organization, like the association of governors, etc,) has recently come out with a guidance document which has a relatively narrow definition of “health care spending”. And unsurprisingly, the insurance companies, led by Karen Ignani (the remarkably effective president of America’s Health Insurance Plans, or AHIP), are incensed that their favorite spending categories, (investments and fraud prevention) are not counted as “health expenditures”. Naturally, they couch this in language calculated to frighten patients into calling their congresscritters: “the current proposal could have the unintended consequence of turning-back-the-clock on efforts to improve patient safety, enhance the quality of care, and fight fraud” according to Ms. Ignani.

Uh-huh. Investments did so much to improve patient safety. And fighting fraud is a cost of doing business, not a direct cost of health care. Now Ms. Ignani is a smart woman; she knows the buttons to push. But I wish they insurance companies would, just once, recognize that the exemption from anti-trust law they enjoy is at least in part a statement of the public’s faith that they will act in the public’s interest. You know, from time to time. So far their record is spotty to a kind reading. (To a fair reading it’s exploitative, in my opinion, but I’ll stick with spotty for now).

Confidence is low

A story in today’s Modern Healthcare (a magazine I just discovered through the good offices of Emily Friedman, who was one of my favorite teachers at BUSPH) (Also, registration required) reports that a significant minority of nurses have little confidence in the institutions where they work, and a remarkable 72% majority feel that the institution where they work understaffs for the work done.

As someone who is not a nurse, but works with a lot of them very regularly, I agree with this assessment on both counts. While it is not unusual for employees to feel they are overworked, nurses are asked to provide direct care to increasing numbers of increasingly ill patients, which requires not only making people comfortable and handing out their meds, but making accurate snap judgements on how they’re doing, whether they’re getting better or worse, how to intervene if things aren’t going well, and generally expected to be the patient’s first line of defense against the system (which we all know patient’s need defending against, ref. IOM report on medical error). Institutions don’t want there to be many nurses (because a good nurse is expensive), and so try to remove a lot of the “direct care” from nursing hands, leaving them with the more technical aspects of care. This ignores a huge part of what a nurse does, though; nurses spend a lot of time with patients in the course of changing the sheets, bathing and toileting, assisting with ambulation, and all of the “direct care” which can be done by others but ought to be done by nurses. Because it’s that time with the patient where the nurse learns the patient’s baseline, and can then judge departures from that baseline, and either intervene themselves, or call other providers to intervene if the problem is outside their scope of practice.

It’s like this: when I was learning physical diagnosis (how to examine people), one of my instructors pointed out the value of seeing as many “normal” things as possible. That way, when I saw something subtly abnormal, I would recognize it as abnormal and investigate, even if I didn’t know what exactly the abnormality was. Realizing that something “doesn’t look right” is a highly valued skill in medicine. Nurses are in a position to look at a patient and recognize, because they’ve spent a lot of time with the patient, that they “don’t look right”. They may not know exactly what is wrong (although usually they do, especially at the higher experience levels), but they know it’s something. The earlier that recognition takes place, the earlier something can be done, and a problem, error or complication avoided.

This is the problem which led the California Nurses Association to demand, and get, mandatory staffing levels in California hospitals. Hospitals moaned loudly, because nurse staffing has traditionally been a management prerogative, but since nursing management (like physician management) has been co-opted by general management (whose priority is profit, even in non-profit institutions), that prerogative has been abused in the service of improving the bottom line. Rather than pay for proper nursing, management would rather buy a new magnet (MRI machine), or outfit a catheterization lab for which they don’t have enough volume, in the hopes of increasing that volume, or do some other thing which increases their “business competitiveness” while decreasing their ability to perform the core function of a hospital, which is to care for the patient. CNA had little confidence that management would protect the core mission when confronted with the desire of physicians and managers (and, let us be honest, patients) for the latest and greatest technology. And my confidence is just as low.

Told you so…

So there’s a story in today’s Boston Globe, which reports that slightly more than half of overweight adults are healthy, as measured by their cholesterol levels and blood pressure (and a few other things, basically measuring ‘metabolic health’). And not a few (about one quarter) of people of ‘normal’ weight were unhealthy by those measures.

Well, that’ll set the fox in the henhouse, won’t it?

Let’s have a look at the original, shall we? It does say about what is reported (have a look), but is interesting for what else it says:

“The independent correlates of 0 or 1 cardiometabolic abnormalities among overweight and obese individuals were younger age, non-Hispanic black race/ethnicity, higher physical activity levels, and smaller waist circumference.”

So, young white people who exercise and have smaller waists than hips are healthier than you might expect based on their body mass index. What does this tell us? Mostly, it tells us that BMI is a blunt instrument with respect to measuring cardiovascular health. If you’re paying attention at all, this is not news, although it is nice to have it confirmed by a data set as large as NHANES (National Health and Nutrition Examination Survey-it’s a Really Big, Really Good data set). Basically, obesity is not as big a problem as fat distribution. To quote the paper: “There is not yet a standardized definition of body size phenotype”. Perhaps we should work on that, because where the fat is, and whether you are ‘physically active’, may mean more in terms of health than BMI alone. So, now wither obesity prevention? Because it’s going to be hard to base any kind of health intervention on BMI, which is what we’ve been doing for a while now.

This matters for a couple of reasons. If you’re going to design an intervention with respect to obesity (and believe, me, a lot of money is going to be spent on this in the upcoming few years), you need to point the money at the right problem. And BMI is looking like the wrong problem. So what is the right problem? We’re getting a grip on it, but we need a ‘standardized definition of body size phenotype’. We also need to get a grip on activity. How do activity and ‘body size phenotype’, whatever we decide that is, interact? Which is more important, or are they interacting terms?

And this matters right now. I interviewed today for a position at a local health care think tank, which has a sizable initiative on obesity intervention. What is the future of that initiative, in light of these findings? It’s not dead, but it might need significant reworking in light of this paper. The nice part is, if I get the job (it’s an internship, but hey, still a job as far as I’m concerned), I might get to do some of the rework.

Ain’t science grand?
