Well-woman exams: the road to poorer health is paved with good intentions

For each full day that I see patients, I generally perform 3 to 4 physical examinations in well children and adults. I am well aware of the evidence that general health checks may not improve health outcomes in adults, as well as the limitations of such studies (which are decades old and included many screening tests that are now known to be ineffective). My sense is that most of the health benefits my patients derive from checkups are not from the examination itself, but from listening and counseling. In a recent Medscape commentary, I observed that guidelines for well-woman care have appropriately moved away from largely pro forma gynecologic exams since the turn of the century:

At that time, it was not unusual for me to screen for cervical cancer in a sexually active teenager, and to advise most women to return for a Pap smear and clinical breast exam every year. I remember our clinic's medical director admonishing the residents not to skip routine breast and pelvic exams in women without symptoms.

However, I am concerned that this positive movement - de-intensifying or eliminating components of the well-woman exam that don't benefit women - appears to have stalled:

Recent federal regulations and recommendations now threaten to replace discontinued components of the well-woman exam with other well-intentioned services that unfortunately have little basis in evidence.

I discussed three examples in my commentary:

FDA-mandated language about breast density in mammography reports, leading to further testing in women with dense breasts: "While we do know that additional testing in women with dense breasts increases false-positive rates, we don't know if it improves breast cancer outcomes or only leads to more anxiety, more biopsies, and more overdiagnosis."

Annual screening for urinary incontinence, "even though the [Women's Preventive Services Initiative] group's own review found insufficient evidence that systematic annual screening improves health outcomes."

Screening for anxiety in all adolescent and adult women, "which has a similar dearth of supporting evidence on benefits and harms."

Each of these recommendations is intended to address a known problem: mammograms are less likely to identify breast tumors in women with higher breast density; urinary incontinence is common, frequently bothersome, and underreported; and anxiety reduces quality of life in many women (and men, for that matter). But a high prevalence of unidentified disease and the availability of effective treatments aren't enough to warrant screening on their own. Women deserve better than preventive care based on good intentions, which in the past led to mistakes such as prescribing menopausal hormone therapy for millions of women who either did not benefit or experienced harm. Instead, they deserve evidence-based, data-driven care.

Reimagining advance care planning

It is difficult to overstate the damage done by the fictional political term "death panel," which claimed that a 2009 legislative proposal to pay physicians for providing counseling to Medicare patients about advance directives and end-of-life care options amounted to a group of federal bureaucrats deciding whether an older or disabled person would be permitted to live or die. Not until 2016 did the Centers for Medicare & Medicaid Services (CMS) create Current Procedural Terminology (CPT) codes that allowed billing for advance care planning services, and clinicians have been slow to use them. According to a recent study in JAMA Internal Medicine, only about 2% of Medicare fee-for-service beneficiaries age 65 years or older had advance care planning visits. As expected, geriatricians and palliative medicine specialists were more likely to use the codes than other physicians. Even so, two-thirds of hospice and palliative medicine specialists did not use the codes at all in 2017, which suggested that billing did not reflect actual counseling practices.

Other articles have documented the challenges of incorporating patients' values and preferences into care plans when they are already experiencing serious illness. An analysis of recorded clinician-family conferences about critically ill patients found that in more than half, "there was no deliberation about how to apply patients' values and preferences in the current clinical situation," and in 1 out of every 4 discussions, the patient's values and preferences were not even mentioned. Similarly, a medical oncologist reflected in Health Affairs about the care team's failure to manage expectations of a patient with advanced (and ultimately fatal) lung cancer who, "because she was looking for rescue," declined to discuss goals of care as an outpatient even as treatments proved ineffective and her health deteriorated:

I'm not sure how well we managed Wendy's care at the end of her life. On the one hand, she achieved her short-term goal of attending the family gathering. On the other hand, she spent nearly the entire last month of her life hospitalized. She died in an intensive care unit, intubated, on a ventilator, and unable to say goodbye to love ones. She was not enrolled in hospice. We don't know whether we met Wendy's goals of care because we never managed to define them.

Two editorials in the March 1 issue of American Family Physician addressed how physicians can prepare patients better for end-of-life decisions by "thinking about [advance care planning] as an iterative and integrative process," rather than as a document to be filled out and then filed away. Primary care teams can use the Serious Illness Conversation Guide to assess patients' understanding of their illness, explore what matters most to them, and communicate goals of care to family members and subspecialists. Lack of training and time constraints remain barriers, however. Innovative residency curricula on advance care planning, such as this medical-legal partnership described in Family Medicine, may improve physicians' comfort level with these conversations. Having Medicare and private insurers pay for advance care planning discussions is a helpful first step, but as Drs. Joanna Paladino and Erik Fromme observed, "clinicians cannot improve the care of people with serious illness alone—to be successful, they need health system changes that support better conversations over the continuum of care."

Unequal treatment: physician payment disparities and their health consequences

As a family physician and medical school faculty member, I'm naturally a big booster of primary care. America needs more generalist physicians, and much of my professional activity involves encouraging medical students to choose family medicine, or, failing that, general pediatrics or general internal medicine. But it's an uphill battle, and I fear that it's one that can't be won without major structural changes in the way that generalist physicians are paid and rewarded for their work.

In a Medicine and Society piece in the New England Journal of Medicine, Dr. Louise Aronson (a geriatrician) described visits with two of her doctors, a general internist and an orthopedist. The primary care physician worked in a no-frills clinic, often ran behind schedule, and devoted much of the visit and additional post-visit time to electronic documentation. The orthopedist worked in a newer, nicer office with an army of medical and physician assistants; generally ran on time; and was accompanied by a scribe who had competed most of the computer work by the end of the visit. Although there are undoubtedly a few family doctors with income parity to lower-earning orthopedists, according to Medscape's 2017 Physician Compensation Report, the average orthopedist makes $489,000 per year, while an average general internist or family physician makes around $215,000 per year. Here's what Dr. Aronson had to say about that:

It would be hard, even morally suspect, to argue that the salary disparities among medical specialties in U.S. medicine are the most pressing inequities of our health care system. Yet in many ways, they are representative of the biases underpinning health care’s often inefficient, always expensive, and sometimes nonsensical care — biases that harm patients and undermine medicine’s ability to achieve its primary mission. ...

Those structural inequalities might lead a Martian who landed in the United States today and saw our health care system to conclude that we prefer treatment to prevention, that our bones and skin matter more to us than our children or sanity, that patient benefit is not a prerequisite for approved use of treatments or procedures, that drugs always work better than exercise, that doctors treat computers not people, that death is avoidable with the right care, that hospitals are the best place to be sick, and that we value avoiding wrinkles or warts more than we do hearing, chewing, or walking.


Medical students are highly intelligent, motivated young men and women who have gotten to where they are by making rational decisions. For the past few decades, as the burden of health care documentation has grown heavier and the income gap between primary care physicians and subspecialists has widened, they have been making a rational choice to flee generalist careers in ever-larger numbers.

The cause of these salary disparities - and the reason that more and more primary care physicians are choosing to cast off the health insurance model entirely - is a task-based payment system that inherently values cutting and suturing more than thinking. I receive twice as much money from an insurer when I spend a few minutes to freeze a wart than when I spend half an hour counseling a patient with several chronic medical conditions. That's thanks to the Resource-Based Relative Value Scale, a system mandated by Congress and implemented by Medicare in 1992 in an attempt to slow the growth of spending on physician services. Every conceivable service that a physician can provide is assigned a number of relative value units (RVUs), which directly determines how much Medicare (and indirectly, private insurance companies) will pay for that service.

As new types of services are developed and older ones modified, the RVUs need to be updated periodically. Since the Centers for Medicare and Medicaid Services (CMS) chose not to develop the in-house expertise to do this itself, it farms out the updating task to the Relative Value Scale Update Committee (RUC), a 31-member advisory body convened by the American Medical Association (AMA) and nominated by various medical specialty societies. Here is where the fix is in. Only 5 of the 31 members represent primary care specialties, and over time, that lack of clout has resulted in an undervaluing of Evaluation and Management (E/M) and preventive services (the bulk of services provided by generalist physicians) compared to procedural services. Although an official AMA fact sheet pointed out that some RUC actions have increased payments for primary care, a 2013 Washington Monthly article countered that these small changes did little to alter the "special deal" that specialists receive:

In 2007, the RUC did finally vote to increase the RVUs for office visits, redistributing roughly $4 billion from different procedures to do so. But that was only a modest counter to the broader directionality of the RUC, which spends the vast majority of its time reviewing, updating—and often increasing—the RVUs for specific, technical procedures that make specialists the most money. Because of the direct relationship between what Medicare pays and what private insurers pay, that has the result of driving up health care spending in America—a dynamic that will continue as long as specialists dominate the committee.


We teach our medical students to recognize that inequities in where patients live, work and play are far more powerful in determining health outcomes than the health care we provide. A child living in a middle-class suburb has built-in structural advantages over a child living in a poor urban neighborhood or rural community, due to disparities in economic and social resources. The same goes for how physicians are paid in the U.S. Until the RUC is dramatically reformed or replaced with an impartial panel, the $3.5 trillion that we spend on health care annually (20 percent of which pays for physician services) will continue to produce shorter lives and poorer health compared to other similarly developed nations.

Apps that detect atrial fibrillation may not improve health

The March 15 issue of American Family Physician included a recommendation statement from the U.S. Preventive Services Task Force (USPSTF) and Putting Prevention Into Practice case study on screening for atrial fibrillation with electrocardiography (ECG). The USPSTF concluded that current evidence is insufficient to assess the balance of benefits and harms of testing for atrial fibrillation in primary care patients without suggestive symptoms. In an accompanying editorial that I solicited, cardiologists John Mandrola and Andrew Foy discussed several potential downsides of ECG screening for atrial fibrillation: low prevalence, a high number needed to screen to prevent one stroke, high costs, false positive results, and uncertainty about the effects of anticoagulants in persons with subclinical atrial fibrillation.

At the American College of Cardiology (ACC) meeting last month, Dr. Mandrola interviewed Dr. Mintu Turakhia, a co-principal investigator of the Apple Heart Study, regarding initial findings reported at the conference. More than 400,000 U.S. adults with Apple Watches installed a paired smartphone app that used an algorithm to analyze heart rate variability and notified users if five out of six samples over a 48-hour period suggested an irregular heart rate. Of the 2100 individuals (~0.5%) who received these notifications, the positive predictive value for ECG-confirmed atrial fibrillation was 84%. The app's sensitivity and false negative rate are unknown because users who did not receive notifications did not have ECG monitoring. Also, the study was not designed to evaluate health outcomes. In a Medscape commentary, Dr. Mandrola chided the ACC for calling so much attention to these preliminary, disease-oriented data:

Given the stark inequities of care in the United States and globally, I question the morality of dedicating this much attention to a study on a low-risk population, a group that already enjoys relatively excellent health. ... Smart watches and digital health will deliver oodles more information. This, along with hype, will surely enrich the makers of devices, and in turn the medical industry. I remain skeptical that it will improve the human condition. It could even make us sicker.

A planned pragmatic randomized trial will enroll adults age 65 years and older to determine if screening for atrial fibrillation and other heart rhythm abnormalities using the Apple Watch app leads to reduced stroke rates and/or improved cardiovascular health. In the meantime, family physicians will likely start seeing more patients for evaluation of possible cardiac rhythm abnormalities detected by wearable devices. A recent JAMA article reviewed the limitations of such devices at detecting atrial fibrillation, tachycardia, and bradycardia and offered a suggested approach to evaluation and management.

Patients, Populations and Policy: Season 1, Episode 2

This is the second of two podcast episodes that I created specifically for my first-year medical student class. It discusses the evolution of physician payment, the major components of the Affordable Care Act, and proposals for future health care reforms. If you haven't yet listened to episode 1, which provides some basic background information on the U.S. health system, you can find it here. And I don't intend to stop at two episodes, so if you like what you hear, please subscribe to the podcast feed to receive notifications when I release more later this year. My P3 podcast will also soon be available on ITunes, Google Play, Spotify, and Stitcher. Thanks for listening!

Nonselective full-tuition scholarships don't produce more primary care physicians

Last August, I wrote about NYU School of Medicine's decision to award full tuition scholarships to all current and future medical students, and my skepticism that this generous policy would achieve my alma mater's stated goals of recruiting a more socioeconomically diverse student body and sending more graduates into primary care fields. I was not the only person to gently criticize NYU's approach to these important issues; a few days later, Kaiser Health News editor and former emergency medicine physician Elisabeth Rosenthal wrote in a New York Times opinion piece that "instead of making medical school free for everyone, NYU - and all medical schools - should waive tuition only for those students who commit to work where they are needed most." As an example, she pointed to selective scholarships awarded by NYU's law school each year to 20 students who commit to careers in low-wage public service. Dr. Rosenthal also argued that since academic medical centers receive billions of dollars in public funds to train new doctors and don't pay taxes due to their nonprofit status, "Every academic medical center should see training the medical work force America needs not as charity but as an obligation, a 'community benefit' of the highest order."

As for increasing diversity, another laudable goal, Dr. Billy Thomas wrote in a JAMA Viewpoint:

If medical school admissions processes continue to be weighted toward metrics [e.g., GPAs, MCAT scores] and the number of minority, disadvantaged, and marginalized applicants remains stagnant, attempts to diversify the health care workforce will fall far short, despite reduced or free tuition. ... The NYU program may increase diversity at NYU, but taken in context with the stagnant national applicant pool, the increased enrollment at NYU may result in a “zero sum effect” on the national health care workforce as it relates to diversity and, by extrapolation, have no significant effect on our efforts to reduce health disparities and improve population health.

When I interviewed prospective Georgetown medical students this year, NYU usually came up in conversation, from the medical diploma hanging on my wall, if nothing else. Of course they had all applied to NYU, and if accepted, they'd most likely attend, no matter how much they loved Georgetown or Hopkins or Harvard or anywhere else without free tuition. Indeed, total applications increased by almost 50 percent, and applications from underrepresented groups more than doubled.

Another problem: according to an analysis of public data on medical school endowments, enrollment, and tuition expenses by two students at Mount Sinai (which had a brief but unsuccessful merger with NYU in the late 1990s), only 20 of 141 U.S. medical schools are financially positioned to afford going tuition-free for all students. Notably, even NYU shrunk its class size by at least a third from its size at the time of my graduation, presumably to lower the cost of providing every student with a scholarship. Like NYU, Harvard, which unsurprisingly tops the list of wealthy schools, doesn't even have a family medicine department, where establishing one would be an investment more likely to pay off for primary care than simply making school free with no service requirement.

Meanwhile, Dr. Bich-May Nguyen, a family physician with whom I've previously collaborated, just published a report in Family Medicine of a survey of 74 physicians who graduated from two BS/MD programs in Texas from 2003 through 2013 that provided full scholarships for college and medical school. 18 of these physicians went into primary care, which is about average for medical students nationally. Dr. Nguyen and her coauthor noted that the motivations for these physicians' specialty choice were similar to those from surveys of physicians who only received partial or no tuition assistance:

People interested in primary care were also interested in serving underserved or minority populations, health promotion, patient continuity, and patient advocacy. ... The second theme was found in statements supporting high income potential, prestige among colleagues, inpatient hospital care, and quick results from interventions. ... Additionally, the respondents most interested in high incomes did not enter primary care.

Ultimately, there are far less expensive solutions to the problems that NYU was supposedly trying to address by waiving medical school tuition. Want a more diverse student body? Admit more minority and low-income students. Want more students to go into family medicine and primary care? Establish and support departments in those fields, and admit more of the types of students who tend to pursue primary care. They won't necessarily have the highest GPAs or MCAT scores or the social advantages bestowed by wealthy parents (and potential future donors), but as the recent college admissions scandal showed, those things are overrated anyway.

Do subspecialist-led guidelines serve patients better - or worse?

In December 2017, the Health News Review blog posted a story questioning why there had been such extensive news coverage of the American College of Cardiology / American Heart Association hypertension guideline but so little of the American Academy of Family Physicians' announcement that it was not endorsing the guideline (the only other news outlets to have reported this decision are the AAFP's own news publication and Medscape). In this case, the AAFP decided to continue to adhere to blood pressure targets established by the JNC-8 hypertension guideline and its joint guideline with the American College of Physicians for adults aged 60 years or older.

Earlier that year, an editorial in the cardiology journal Hypertension criticized the ACP-AAFP guideline for the lack of "experts" on its panel. The 30 named authors of this 3-page piece, most of whom I suspect did not meet the International Committee of Medical Journal Editors' authorship criteria, collectively have a list of disclosures of commercial conflicts of interest that takes up nearly a column of text. Those concerns aside, Dr. Franz Messerli and colleagues stated correctly that "guidelines are traditionally scripted by a panel of experts who are intimately familiar with the topic in question." They went on to compare the glittering resumes of the JNC-8 panel ("most of them were indeed true experts") with the more pedestrian ones of the ACP/AAFP panel and asserted that the latter's dearth of expertise did not qualify them for guideline development:

As per PubMed, 3 of the 7 guideline authors have never authored an article on hypertension and 1 has coauthored a single study only. Moreover, not one of the authors of the ACP/AAFP guideline is known to be a hypertension specialist certified by the American Society of Hypertension or of the American Heart Association Council for High Blood Pressure. ... No ACP/AAFP guideline author is currently serving on the editorial board of a journal dealing with hypertension. ... The mere fact that you know how and when to prescribe hydrochlorothiazide does not make you an expert in hypertensive cardiovascular disease.

This argument echoed past complaints by subspecialty groups that the U.S. Preventive Services Task Force (USPSTF), made up entirely of primary care clinicians, could not possibly know what it was doing when it recommended fewer screening mammograms (without any radiologists!) or less prostate-specific antigen testing for prostate cancer (without any urologists!)

The question is not whether subspecialists should be involved in developing guidelines for diagnosis and management of common conditions such as hypertension: of course they should be. The question is, on what level? At the guideline review and revision phase (ACP/AAFP) or in developing the key recommendations? The ACC/AHA selected as one of its guideline co-chairs Dr. Paul Whelton, a renowned expert in hypertension who was the principal investigator for the SPRINT study, the only major trial to show that a blood pressure target of 120/80 yielded more benefits than harms compared to a blood pressure target of 140/90 in a selected group of very high-risk patients. In recognition of this intellectual bias, Dr. Whelton was relieved from chairing duties when SPRINT came up, but apparently was able to fully participate in the discussion and vote.

I had the pleasure of meeting Dr. Whelton at a conference a few years ago and came away enormously impressed by his intelligence and equanimity. But it's very hard for anyone to see something - in this case, harms of lower blood pressure thresholds - if your scientific reputation depends on your overlooking it. Also, in my experience as a staffer for the USPSTF, panel members who did not treat the condition being screened for were able to follow the evidence without being biased by clinical experience. Pediatricians who weren't conditioned to order yearly mammograms or obstetrician-gynecologists who never ordered PSA tests were more often assets than liabilities on these topics.

Primary care clinicians, particularly family physicians, have unrivaled expertise in treating the whole person, not only one body part or organ system. As I noted in a Medscape commentary on the ACC/AHA hypertension guidelines, "Cardiologists have the luxury of only needing to be concerned with cardiovascular disease, but the vast majority of my patients with hypertension have comorbid chronic conditions and take several medications. Adding one more anti-hypertensive drug means more potential side effects, medication interactions, and costs to the patient and the health system." Kudos to the AAFP for having the courage to stick with the evidence and buck the one-low-blood-pressure-target-fits-all trend.

Improving outcomes that matter for patients with type 2 diabetes

When comparing therapies for type 2 diabetes, physicians, patients, and quality measures often get caught up in the disease-oriented outcome of glycemic control. However, a 2014 editorial in American Family Physician pointed out that of the medications then available to lower blood sugar levels, only metformin reduced mortality and clinically relevant complications. Since that time, studies of some newer diabetes medications have demonstrated mortality benefits in patients with cardiovascular disease. However, the best second-line medication after metformin remains unclear. Although the World Health Organization guideline recommended inexpensive sulfonylureas as second-line therapy in low-resource settings, the American College of Physicians and the American Academy of Family Physicians suggested "the choice of drug [after metformin] should be based on a conversation with the patient about benefits, possible harms, and cost."

In the February 15 issue of AFP, Drs. Joshua Steinberg and Lyndsay Carlson applied the STEPS criteria (safety, tolerability, effectiveness, prince, and simplicity) to each of the 10 categories of diabetes medications (including insulin). Their analysis confirmed that metformin should be first-line pharmacotherapy for most persons with type 2 diabetes. Other key points from this article include:

Safety - Sulfonylureas, insulins, meglitinides, and pramlintide increase risk of hypoglycemia. Metformin and acarbose require monitoring, dose adjustments, or discontinuation in patients with chronic kidney disease.

Tolerability - Side effects across different drug classes range from gastrointestinal effects (metformin, acarbose, meglintinides, pramlintide, GLP-1 receptor agonists, SGLT-2 inhibitors) to weight gain (sulfonylureas), edema (TZDs), severe arthralgias (DPP-4 inhibitors), and genital and urinary tract infections (SGLT-2 inhibitors).

Effectiveness - Recent trials showed improved patient-oriented outcomes from some GLP-1 receptor agonists and SGLT-2 inhibitors in patients at high cardiovascular risk or with known cardiovascular disease. Acarbose also reduces cardiovascular events.

Price - Metformin, acarbose, sulfonylureas, and generic pioglitazone are the most affordable options.

Simplicity - Acarbose and meglitinides are taken three times daily before meals, while insulins, GLP-1 receptor agonists, and pramlintide require subcutaneous injections.

Living, teaching, and valuing the pursuit of health equity

My younger son, who turned seven last week, had a minor health scare in December. After a few days of a cough and runny nose, one morning he complained that he didn't want to walk because his legs hurt. We gave him some liquid ibuprofen, wondering if these were just growing pains, but the pain kept coming back. Adding to our concern, this is a child with a high threshold for pain; for example, he barely blinked when having a cavity filled at age three. Over the next week or so, he developed red and purple blotches on his lower legs and feet that looked like this and this.

After consultations with our family doctor and other physician friends and family, he was diagnosed with Henoch-Schonlein purpura, a relatively rare condition that, fortunately, resolves spontaneously in most but can cause kidney disease in up to half of affected patients. Through the first week of January, his legs continued to hurt off and on as the rash slowly faded, but his kidney function remained normal, and the only medical bills we received were from a single clinic visit and some outpatient blood tests covered by our health insurance. We were lucky, not only because my son avoided complications, but because we had the advantage of being well positioned to obtain further care for him had they occurred.

Adjusted U.S. ESRD incidence rates, 2000-2015

Last week, I led a team-based learning exercise for the first-year class at Georgetown University School of Medicine on disparities in kidney (renal) disease. Not only are some racial and ethnic groups more likely to suffer from end-stage renal disease (when kidney function has deteriorated to the point that dialysis or a kidney transplant is often needed), but this unequal burden is unevenly distributed geographically, reflecting disparities in socioeconomic status. The graphic below, showing much higher rates of end-stage renal disease in the majority-African American northeast and southeast quadrants of Washington, DC, coincides with my years of practicing in these areas and noticing clusters of fast-food chains and dialysis centers around primary care clinics.

End-stage Renal Disease in Washington, DC

Similar large disparities in mortality and life expectancy are present nationally. In a 2006 paper, Dr. Christopher Murray (profiled in Jeremy Smith's "Epic Measures") described "Eight Americas," collections of U.S. counties defined by a mixture of race, geography, socioeconomics, and population density that demonstrated striking differences in mortality patterns. In a more recent analysis, Dr. Murray and colleagues concluded that geographic disparities in life expectancy have worsened over the past three decades: "Compared with the national average, counties in Colorado, Alaska, and along both coasts experienced larger increases in life expectancy between 1980 and 2014, while some southern counties in states stretching from Oklahoma to West Virginia saw little, if any, improvement over this same period."

Observing that overall U.S. life expectancy has been falling since 2015 after decades of steady improvement, a recent editorial in the Annals of Internal Medicine called on health research funders to "honestly recognize the interactive roles of biology and the socioeconomic and political environment ... [and] align health research resources toward an integrative model of science that seriously investigates the socioeconomic and political determinants of health alongside the biological ones." Reducing disparities in HIV/AIDS, for example, will require not only more clinical resources and affordable drugs, but more studies of policy interventions to improve social and living conditions that increase the risk of acquiring HIV infections in the first place. This means going beyond meeting individual-level social needs to changing the conditions that make people sick in communities and populations (including the Eight Americas).

As "value-based" health care payment models rapidly expand, based on the argument that we ought to be paying for good health outcomes rather than the volume of health services, we are recognizing that social determinants put some populations at a health disadvantage that effective interventions, such as increasing primary care physician supply, cannot fully overcome. As a result, physicians and health systems who serve underserved populations may be judged as providing "poor quality" care (and paid less) simply because their patients' outcomes were so much worse to begin with.

What can be done about this? Dr. Krisda Chaiyachati and colleagues have argued for a "disparities-sensitive frame shift" in value-based payment:

The health care industry cannot ignore true instances of poor quality, but it also should not worsen health care for at-risk populations. To address this tension, value-based payment models should ... integrate measures of equity into hospitals' financial calculus, incentivizing hospitals to tackle the disparities challenge without losing sight of quality. ... Concurrently, we should start paying hospitals to reduce disparities directly.

Similarly, Dr. Christopher Frank observed that "value-based payments will only work when we decide that health equity is an important value to reward."

Make no mistake: I'm happy that my son got well and has stayed well. I'm not happy that it is inherently more difficult for other children to have the positive outcome that he experienced. Reducing these disadvantages and pursuing health equity informs my clinical practice, teaching in population health, and writing projects.

Does subspecialist-oriented medical care add sufficient value to be worth the added cost?

The latest Graham Center One-Pager in the February 1 issue of American Family Physician contained good news and bad news for primary care. Examining the entry of medical students into residency programs between 2008 and 2018, Dr. Robert Baillieu and colleagues reported that the total number of graduates who entered Family Medicine through the National Residency Matching Program increased by 64% over the past decade. However, the annual proportion of U.S. allopathic (MD) graduates remained static at around 50%, reflecting the continued migration of most students into higher-paying medical subspecialties.

Two of my previous posts reviewed research demonstrating that students entering family medicine are more likely to make patient-centered, cost-conscious clinical decisions and that primary care physicians who trained in low-cost hospital service areas are more likely to provide high-value care in practice. The late health services researcher Barbara Starfield, MD, MPH once argued that a lack of investment in primary care is a major reason that the U.S. health system spends so much but produces poor outcomes:

The thing that is wrong with our current health care system is that it is not designed to produce the best effectiveness, efficiency and equity in health services because it is too focused on things that are unnecessary and of high cost rather than arranging services so that the most needed services are provided when needed and with high quality. [This] is the case because the country has not put sufficient emphasis during the past 50 years on a good infrastructure of primary care. ... We have done a reasonably good job at making subspecialty care available, but a lot of subspecialty care is not necessary if you have good primary care. So we end up with a very expensive system that does things unnecessarily.

In a recent nationally representative study in JAMA Internal Medicine, Dr. David Levine and colleagues examined associations between receipt of outpatient primary care and care value and patient experience. Using Dr. Starfield's definition of primary care as "first-contact care that is comprehensive, continuous, and coordinated," the authors compared the quality and experience of care in more than 70,000 U.S. adults with and without primary care who participated in the Medical Expenditure Panel Survey from 2012 to 2014. 70% of the primary care clinicians identified by patients were family physicians (19% were general internists). After adjustment for potential sources of confounding, respondents with primary care were more likely to receive high-value preventive care and counseling and to report better patient experiences than those without primary care. However, respondents with primary care were also slightly more likely to receive low-value prostate cancer screening and antibiotics for respiratory infections.

In an accompanying editorial that noted the disparity in primary care investment between the U.S. (7% of total health care spending) and the health systems of other industrialized nations (20%), Dr. Allan Goroll asked: "Does primary care add sufficient value to deserve better funding?" Although this formulation recognizes that the American status quo is a subspecialist-oriented health system, it seems to me that the question ought to be, "Does subspecialist-oriented medical care add sufficient value to primary care be worth the added cost?" From this study and previously published evidence, the answer appears to be no.

What do recent publications mean for men with localized prostate cancer?

From 2012 to 2018, the U.S. Preventive Services Task Force and the American Academy of Family Physicians recommended not screening for prostate cancer, based on evidence that the then-widespread practice produced no net benefit. As a result, fewer family physicians subsequently screened their patients with the PSA test, and fewer men were diagnosed (or overdiagnosed) with localized prostate cancer. However, the USPSTF's recent change to a more permissive approach to PSA-based screening has increased the likelihood that more men will need to make difficult decisions regarding what to do about a prostate cancer diagnosis.

As I discussed in a previous AFP Community Blog post, surveyed men with newly diagnosed localized prostate cancer expected to gain a whopping 12 years of life expectancy by undergoing surgery or radiation. In fact, two randomized, controlled trials found no gains in prostate cancer-specific or all-cause mortality. After nearly 20 years of follow-up, the U.S. Prostate Cancer Intervention versus Observation Trial (PIVOT) reported in 2017 that radical prostatectomy reduced the likelihood of treatment for asymptomatic, local, or biochemical (PSA) disease progression compared to observation, but caused more urinary incontinence, erectile dysfunction, and limitations in activities of daily living. Similarly, the U.K. Prostate Cancer for Testing and Treatment (ProtecT) trial found that active surveillance was comparable to radiotherapy or prostatectomy, with a slightly greater likelihood of clinical progression and metastatic disease in the active surveillance group.

A 2018 article reviewed the evolving National Comprehensive Cancer Network guidelines for treatment of localized prostate cancer, which recommend incorporating comorbidity-adjusted life expectancy into screening and treatment decisions:

The comorbidity-adjusted life expectancy is particularly important because the number of comorbid diseases is among the most significant predictors of survival after prostate cancer treatment. Prostate cancer is usually slow growing, and the survival benefit of treatment may present only after 10 years. Therefore, patients with low-risk or very low-risk prostate cancer should be treated only if the patient has a comorbidity-adjusted life expectancy of at least 10 years.

An older Swedish randomized trial comparing radical prostatectomy to watchful waiting in men with predominantly clinically-detected (rather than PSA-detected) localized prostate cancer found that radical prostatectomy was associated with less than 3 years of life gained after 23 years of follow-up. Altogether, the evidence suggests that curative treatments may be worthwhile for selected men with symptoms, but that there is little or no benefit to looking for prostate cancer in men who feel well.

When deprescribing is the best medicine

Physicians who care for older adults or others with multiple chronic conditions understand that deprescribing unnecessary or inappropriate therapies is central to providing high-quality care and improving patient safety. An editorial by Drs. Barbara Farrell and Dee Mangin in the January 1 issue of American Family Physician reviewed the health risks associated with polypharmacy (taking five or more chronic medications) and provided a table of resources for each step of the deprescribing process, including several evidence-based guidelines co-written by the authors. AFP's Practice Guidelines department summarized their guideline on deprescribing antipsychotics for dementia and insomnia last year and reviewed how to taper benzodiazepine receptor agonists for insomnia in adults in the January 1 issue.

A 2018 systematic review in the British Journal of General Practice reviewed data from 27 randomized, controlled trials of deprescribing a range of drug classes in adults aged 50 years or older in primary care settings. In 19 studies, at least half of patients in the intervention groups were able to stop their medications completely, and adverse effects were uncommon. However, the risk of "relapse" (needing to resume the drug after completely discontinuing it) ranged from 2 to 80 percent.

Patient expectations, medical culture, and organizational constraints can present barriers to deprescribing. A qualitative study of New Zealand primary care physicians in the Annals of Family Medicine described deprescribing as "swimming against the tide." Study participants recommended several practice and system-level interventions to support deprescribing that could also be applied to practices in the U.S.:

- Targeted funding for annual medicines review
- Computer alerts to prompt physicians’ memories
- Computer systems to improve information sharing between prescribers
- Improved access to non-pharmaceutical therapies
- Research to build the evidence base in multimorbidity, education and training
- Ready access to expert advice and user-friendly decision support
- Updating guidelines to include advice on when to consider stopping medicines
- Tools and resources to assist in the communication of risk to patients
- Activating patients to become more involved in medicines management and alert to the possibility that less might be better

Along those lines, the AFP editorial also provided a Table of examples of language that family physicians can use to discuss deprescribing with patients and facilitate shared decision-making.

Birthday reflections: envisioning my third act

I'm celebrating my 43rd birthday today, and nearly a decade of blogging at Common Sense Family Doctor. Although 2018 was the first year in which I wrote fewer than one post per week (46 total), I haven't slowed my writing output overall, authoring or co-authoring ten journal articles or textbook chapters last year and kicking off 2019 with a new study in the Journal of the American Board of Family Medicine on conversations on Twitter about women and Black men in medicine. I am grateful to my longtime colleague Dr. Ranit Mishori (@ranitmd) for coming up with this novel research idea and inviting me to join the team.

The changing of the calendar prompts me to reflect more on my career arc as a family physician, researcher, educator, and author. I have been thinking of my career thus far as an ongoing series of "acts," each lasting for several years. The first act began in 2004 with a year-long editing and faculty development fellowship at Georgetown, continued through my time as a medical officer at AHRQ, followed by a year working in urgent care, and concluded with my re-joining the family medicine department as a full-time faculty member and associate deputy editor of American Family Physician and earning my Master of Public Health degree from Johns Hopkins.

In the second act, beginning around 2012-2013, I gradually built my outpatient primary care practice in northwest DC (a handful of patients found me first through my blog); developed and enhanced medical school courses and a fellowship program involving population health, health policy and advocacy; and was promoted to professor of family medicine and deputy editor of AFP. To be sure, there have been setbacks along the way, including, recently, the disappointment of not advancing to the interview stage in my application for the open editor position at the Annals of Family Medicine.

2019 feels to me like the start of Act 3, although I can't fully articulate why. Maybe it's because in my 15th year of practice I have clearly entered mid-career. My patients are getting older, and more of them now struggle with chronic diseases and chronic pain and are spending time in various local hospitals. With my paths to editorial leadership of prominent family medicine journals closed off for at least the next decade (barring the unexpected), I have turned my energies toward developing new features such as AFP's Lown Right Care department and, together with collaborators at Lown, Georgetown, and in Louisiana, am working on a systematic review for the first time in years. My public speaking continues to focus on overuse, particularly of screening tests whose benefits are overvalued and harms are underappreciated. My four kids (ages 4 through 12) keep growing, my wife's house calls practice and nonprofit are thriving, and our family has no plans to leave the DC area anytime soon - again, barring the completely unexpected.

Act 3. The curtain rises. What does this next act have in store for me?

Guest Post: How the medical profession can help heal divisions as well as diseases

Richard Gunderman, MD, PhD, Indiana University

Medicine need not be confined to the role of cultural bellwether, a sheep with a bell on its neck that reveals where the whole flock is headed. Along with other professions such as law, clergy and education, medicine can and should play the leadership role of a shepherd, helping our society to develop more thoughtful, balanced and generous approaches to the challenges that face us. After all, the word doctor means teacher, and our culture needs the best instruction we can offer. The dawn of a new year makes the time ripe for such a shift in medicine’s role.

Doctors as teachers

In serving as educators, doctors have many resources to draw on. They are among the best educated groups in our society, having pursued one of our the longest and most intense courses of study. In practice, they regularly participate in moments that help to clarify what life is all about – birth and death, growth and aging, suffering and relief. And they serve as trusted confidantes and counselors to patients and families at some of life’s most meaningful moments.

Popular culture has reflected an erosion of the doctor as teacher and role model. In the 1960s and 70s, television doctors such as Dr. Kildare and Marcus Welby epitomized virtues such as dedication and compassion. Then along came “M.A.S.H.” and “St. Elsewhere,” which adopted a more irreverent attitude toward medicine and the people who practice it. By 2004’s “House,” which ran for eight seasons, the doctor had degenerated into a clever but deeply misanthropic opioid addict.

First, do no harm

As a physician and educator, I think that, for medicine to help heal our culture, doctors must embrace their role as advocates for principles that have long represented the core of the healing professions. Although “Primum non nocere, or ”First, do no harm,“ does not appear in the writings of the "father of medicine” Hippocrates, it is often cited as medicine’s first principle. And the idea that doctors should avoid harm is part of the modified Hippocratic Oath that most doctors take when they graduate from medical school.

This principle does not imply that doctors should never harm. After all, no surgeon could ever operate and no oncologist could ever administer chemotherapy if they rigorously adhered to it. It means instead that risks and harms must always be balanced against benefits, and that where the balance is too uncertain or unfavorable, it is better to do nothing. More broadly speaking, we should avoid saying things or acting in ways that cause needless injury.

What would “Do no harm” look like in our popular culture? First, it would mean eschewing personal attacks, which seek to label people as unworthy, disgusting, or evil. In public discourse, our goal should be to understand different points of view, to educate one another, and to take the interests of others into account in arriving at decisions. Physicians are expected to take good care of even patients they find disagreeable, and this an outlook sorely deficient in the U.S. today.

Get the whole story

A second habit deeply ingrained over the course of medical training is to recognize that there are usually more than two sides to any question. Suppose a patient complains of pain in the right lower quadrant of the abdomen, a classic symptom of appendicitis. Only poor physicians would confine their attention to the question, “Is it appendicitis or not?” The real issue at hand is to determine what is causing the pain and what needs to be done about it.

In popular culture, complex matters are often reduced to highly simplified dichotomies, in which the two sides are portrayed as sporting white and black hats. It seems as though all Americans need to know is whether a person is a Democrat or Republican, a conservative or a liberal, or a reader of The Washington Post or The Wall Street Journal. In fact, however, making good choices requires an understanding far deeper than which side of a political divide a person is on.

Good doctors learn quickly that a cursory inspection can be deeply misleading, as a story once told by a colleague reveals. An elderly, disheveled, incoherent woman was brought to the emergency room with a broken arm. The staff took her for a homeless person. Later, however, she started to make sense, and provided her phone number. When her family came to pick her up, they arrived in a chauffeured limousine. In this as in so many cases, what first met the eye turned out to be quite deceptive.

Put service before self

To become really good doctors, medical students need to learn something: Patients do not exist to provide careers to physicians; instead, physicians exist to care for patients. Like other professionals, doctors need to put the interests of their patients first. The overarching goal is not to advance the physician’s career, to generate more income, or to secure the business interests of a medical practice or hospital. The goal is to care well for the patient.

The founders of the U.S. knew that human beings are not angels, but they also believed that people can look beyond narrow self-interest and do what is best for others and the larger whole. They knew that serving a purpose beyond self is one of the surest ways to find meaning and purpose in life, and that those who contribute the most often lead the fullest lives. They bet their own lives on the proposition that Americans could answer the call of their better selves.

By serving as exemplars of what a life of service looks like in communities across the country, doctors and other professionals can remind Americans of all ages what human beings at their best are really capable of. To look out only for number one is to lose hope in neighbors, communities and society. To get to know others, to take an interest in their stories, and to reach out and serve when they need help and support is one of the signs of a hopeful, thriving culture.

The idea of medicine as a cultural beacon of goodness may seem profoundly counter-cultural. Our appetite seems much greater for stories of doctors whose financial or sexual misconduct has disgraced themselves and the profession. Yet for the professions to play a role in reshaping our habits of mind and heart, their members must act courageously, not waiting until the cultural winds have shifted but letting their better voices speak even when no one else seems to be listening.The Conversation
