Guest Post: Medical schools are no place to train physicians (Part 2 of 2)

This is the second of two guest posts by Dr. Josh Freeman. Part 1 is available here.

**

The fact is that most doctors who graduate from medical school will not practice in a tertiary academic health center (AHC), but rather in the community, although the other fact is that a disproportionate number of them will choose specialties that are of little or no use in many communities that need doctors. They will, if they can (i.e., if their grades are high enough) often choose subspecialties that can only be practiced in the high-tech setting of the AHC or the other relatively small number of very large metropolitan hospitals, often with large residency training programs. As they look around at the institution in which they are being educated, they see an enormously skewed mix of specialties. For example, 10% of doctors may be anesthesiologists and there well may be more cardiologists than primary care physicians. While this is not the mix in world of practice, and still less the mix that we need to have for an effectively functioning health system, it is the world in which they are being trained.


The extremely atypical mix of medical specialties in the AHC is not “wrong”; it reflects the atypical mix of patients who are hospitalized there. It is time for another look at the studies that have been done on the “ecology of medical care”, first by Kerr White in 1961 and replicated by the Robert Graham Center of the American Academy of Family Physicians in 2003, and represented by the graphic reproduced here. The biggest box (1000) is a community of adults at risk, the second biggest (800) is those who have symptoms in a given month, and the tiny one, representing less than 0.1%, is those hospitalized at an academic teaching hospital. Thus, the population that students mostly learn on is atypical, heaving skewed to the uncommon; it is not representative of even all hospitalized people, not to mention the non-hospitalized ill (and still less the healthy-but-needing-preventive care) in the community.

Another aspect of educating students in the AHC is that much of the medical curriculum is determined by those non-physician scientists who are primarily researchers. They not only teach medical students, they (or their colleagues at other institutions) write the questions for USMLE Step 1. They are often working at the cutting edge of scientific discovery, but the knowledge that medical students need in their education is much more basic, much more about understanding the scientific method, and what constitutes valid evidence. There is relatively little need, at this stage, for students to learn about the current research that these scientists are doing. Even the traditional memorization of lots of details about basic cell structure and function is probably unnecessary; after 5 years of non-use students likely retain only 10% of what they learn; even if they need 10% -- or more – in their future careers, there is no likelihood that it will be the same 10%.

We have to do a better job has of determining what portion of the information currently taught in the “basic sciences” is crucial for all future doctors to know and memorize, and we also need to broaden the definition of “basic science” to include the key social sciences of anthropology, sociology, psychology, communication, and even many areas of the humanities such as ethics. This is not likely to happen in a curriculum controlled by molecular biologists.

Medical students need a clinical education in which the most common clinical conditions are the most common ones they see, the most common presentations of those conditions are the most common ones they see, and the most common treatments are the ones they see implemented. They need to work with doctors who are representative, in skills and focus, of the doctors they will be (and need to be) in practice. Clinical medical education seems to work on the implicit belief that ability to take care of patients in an intensive care unit necessarily means one is competent to take care of those in the hospital, or that the ability to care for people in the hospital means one can care for ambulatory patients, when in fact these are dramatically different skills sets.

This is not to say that we do not need hospitals and health centers that can care for people with rare, complicated, end stage, tertiary and quarternary disease. We do, and they should have the mix of specialists appropriate to them, more or less the mix we currently have in AHCs. And it is certainly not to say that we do not need basic research that may someday come up with better treatments for disease. We do, and those research centers should be generously supported. But their existence need not be tied to the teaching of medical students. The basic science, and social science, and humanities that every future doctor needs to learn can be taught by a small number of faculty members focused on teaching, and does not need to be tied to a major biomedical research enterprise.

Our current system is not working; we produce too many doctors who do narrow rescue care, and not enough who provide general care. We spend too much money on high-tech care and not enough on addressing the core causes of disease. If we trained doctors in the right way in the right place we might have a better shot at getting the health system, and even the health, our country needs.

Guest Post: Medical schools are no place to train physicians (Part 1 of 2)

Dr. Josh Freeman is Professor and Chair of the Department of Family Medicine at the University of Kansas. His research interests include medical education, faculty development and curricular innovation, and health care for underserved populations. This is the first of two guest posts that were originally published on his blog, Medicine and Social Justice. Part 2 is available here.

Doctors have to go to medical school. That makes sense. They have to learn their craft, master skills, and gain an enormous amount of knowledge. They also, and this is at least as important, need to learn how to think and how to solve problems. And they need to learn how to be life-long learners because new knowledge is constantly being discovered, and old truths are being debunked. Therefore, they must learn to un-learn, and not to stay attached to what they once knew to be true but no longer is. They also need, in the face of drinking from this fire-hose of new information and new skills, to retain their core humanity and their caring, the reasons that (hopefully) most of them went into medicine.

Medical students struggle to acculturate to the profession, to learn the new language replete with eponyms, abbreviations, and long abstruse names for diseases (many are from Latin, and while they are impressive and complicated, they are also sometimes trite in translation, e.g., “itchy red rash”). They have to learn to speak “medical” as a way to be accepted into the guild by their seniors, but must be careful that it does not block their ability to communicate with their patients; they also need to continue to speak English (or whatever the language is that their patients speak). “Medical” may also offer a convenient way of obscuring and temporizing and avoiding difficult conversations (“the biopsy indicates a malignant neoplasm” instead of “you have cancer”). But there needs to be a place for them to learn.

So what is wrong with the places that we are teaching them now? Most often, allopathic (i.e., “MD”) medical schools are part of an “academic health center” (AHC), combined with a teaching hospital. They have large biomedical research enterprises, with many PhD faculty who are, if they are good and lucky, are externally funded by the National Institutes of Health (NIH). Some or many of them spend some of their time teaching the “basic science” material (biochemistry, anatomy, physiology, microbiology, pharmacology, pathology) that medical students need to learn.

By “need to learn” we usually mean “what we have always taught them” or “what they need to pass the national examination (USMLE Step 1) that covers that material.” This history goes back 100 years, to the Flexner Report of 1910. Contracted by the AMA, educator Abraham Flexner evaluated the multitude of medical schools, recommended closing many which were little more than apprenticeship programs without a scientific basis, and recommended that medical schools be based upon the model of Johns Hopkins: part of a university (from the German tradition), grounded in science, and based in a core curriculum of the sciences. This has been the model ever since.

However, 100 years later, these medical schools and the AHCs of which they are a part have grown to enormous size, concentrating huge basic research facilities (Johns Hopkins alone receives over $300 million a year in NIH grants) and tertiary and quarternary medical services – high tech, high complexity treatment for rare diseases or complex manifestations of more common ones. They have often lost their focus on the health of the actual community of which they are a part.

This was a reason for two rounds of creating “community-based” medical schools, which use non-university, or “community”, hospitals: the first in the 1970s and the second in the 2000s. Some of these schools have maintained a focus on community health, to a greater or lesser degree, but many have largely abandoned those missions as they have sought to replicate the Hopkins model and become major research centers. The move of many schools away from community was the impetus for the “Beyond Flexner” conference held in Tulsa in 2012 and for a number of research studies focused on the “social mission” of medical schools.

The top ten Common Sense posts of 2013

The past year has been a productive one for me professionally. I became an Associate Professor at Georgetown, completed my Master of Public Health degree, made national television and radio appearances to discuss lung cancer screening on NBC News and NPR, and was appointed to a four-year term as a member of the American Academy of Family Physicians' Commission on Health of the Public and Science. My most rewarding professional activity, however, continues to be writing for Common Sense Family Doctor. Below are links to and excerpts from the ten posts in 2013 that have received the most page views, with the top post viewed 6443 times to date.

1. PSA testing: excerpts from a roundtable discussion  (January 5)

Even if people don’t follow the U.S. Preventive Services Task Force recommendations and discontinue prostate screening, I hope that we will have improved the quality of discussions patients are supposed to be having with their physicians about what their risk is, what outcomes they value, and what they are willing to endure to make sure that they don’t develop late stage prostate cancer.

2. Why don't clinicians discuss cancer screening harms? (November 3)

More than 90 percent of primary care clinicians aren't telling patients that there are downsides to undergoing routine mammograms, colonoscopies, and Pap smears. Why not? Is it because they aren't familiar enough with the data to accurately describe these harms? Or is it because they fear that patients who receive information about cancer screening harms will choose to decline these tests?

3. Guest Post: Why the Direct Primary Care Model would benefit poor patients (September 6)

With direct pay models, actual health care costs can be kept much lower and made much more affordable. Also, since direct pay models typically care for smaller patient panels, patients have more time with their primary care team to address the myriad of life issues that affect their health.

4. Concerns about calcium supplements (February 8)

Is it time to abandon routine calcium supplementation in healthy adults? If not, what additional evidence do we need?

5. Breast cancer and the Angelina Jolie effect (May 15)

Will the Angelina Jolie effect turn out to be a spike in the rates of women being tested for the mutations in their BRCA genes? If so, it's likely that many more women will be harmed than helped. BRCA mutations are rare, affecting 2 to 3 per 1000 women. The vast majority of women who develop breast cancer do not carry these mutations and will not benefit from testing.

6. Should you be screened for lung cancer? Maybe not, and here's why (July 29)

For lower-risk patients, for whom the potential lifesaving benefits of CT scans are very small, the downsides of the screening test become considerably more important. Screening tests have harms just like any other medical procedure, and it's important for your doctor to thoroughly review those harms with you if you are considering screening.

7. Screening-illiterate physicians may do more harm than good (July 13)

The Institute of Medicine has identified low levels of health literacy as a major obstacle to ensuring optimal health and quality of care. But how can physicians expect our patients to make informed decisions regarding screening tests when large numbers of us are functionally illiterate regarding basic screening concepts?

8. The future of medicine is low-tech and high-touch (May 8)

Yes, robots and smartphones can and will play vital roles in the future of medicine. But if we really want sick patients to have the best chance to get better - and healthy patients to avoid getting sick in the first place - then we should do everything in our power to support low-tech and high-touch interventions too.

9. Unintended consequences of "pregnancy prevention" (February 5)

Defining pregnancy as a disease to be prevented is not just a matter of semantics. An overly interventionist approach to pregnancy is largely responsible for the current U.S. rate of one in 3 babies being born by Cesarean section, and predictions that it may soon approach 50 percent.

10. $10 billion per year to train the wrong physicians (June 18)

Where physician production is concerned, you get what you pay for. Medicare pays a disproportionate amount of its nearly $10 billion per year in subsidies to institutions that produce mostly subspecialists, at the expense of training sorely needed family physicians and other generalists whose presence has been shown time and again to deliver better health outcomes.

Very best wishes for a happy and healthy 2014!
