It Ain’t What You Don’t Know That Gets You into Trouble. It’s What You Know for Sure That Just Ain’t So”[i]

Dogma is interesting. It often arises in the absence of unassailable data. Almost all data start as derivatives from imperfect information. This would suggest that these data should then be reconsidered. Sometimes follow up studies, which are hopefully “better”, support dogma. Frequently, they don’t.

Consider the case of an elderly man with carcinoma of the bladder. After two trans urethral tumor resections, he was put on induction intravesicular BCG bladder therapy and then maintenance for a planned total of 3 years of periodic BCG installations.

Recently (about February 2019) a national/worldwide shortage of BCG became apparent, and distribution from Merck changed. There just wasn’t enough BCG to treat everyone with bladder cancer for the full 3 years as the “standard of practice” dictated. The American Urological Association (AUA) then re-evaluated the evidence on duration of maintenance therapy. The review suggested that more than a year of every 3-month maintenance therapy might have very little incremental benefit over one or two years. The incremental benefit of a third year of maintenance therapy was small. In addition, many of the prior AUA recommendations for therapy have a “Level C” certainty[ii]. It appears that the “standard of care” was based on the way that the initial study of BCG as immunotherapy for Non-Muscle Invasive Bladder cancer was performed[iii], without careful analysis of follow up information.

This experience suggests that when a therapy works, practitioners tend to follow the recommendations as they were written. These recommendations were based on an understanding of the biology of an illness at the time they were written. However, as our understanding of the biology of disease becomes clearer, these shifts in understanding might justify another look at treatment. Ideally this would be done with a Randomized Controlled Clinical Trial, but a registry of therapies for disease should be an acceptable second approach to get data that may overturn existing dogma.

There are examples of dogma, sometimes based on early, imperfect data and sometimes based on opinion, that isn’t/wasn’t effectively challenged, in the field of cardiovascular medicine. These include believing that thrombosis was not the cause of myocardial infarction; and believing that revascularization is superior to non-interventional therapy in coronary artery disease.

Intuition would suggest that Coronary Artery Bypass Grafting (CABG), described by Favalaro in 1967, should be lifesaving in patients with CAD. “Common sense” and the VA cooperative trial said that better blood flow to the heart had to prevent MI and death (the VA trial really only said L-main disease was the lesion in which surgery prevented death). Later trials, notably the Coronary Artery Surgery Study (CASS) showed that there was no major mortality benefit[iv].

Later, still working on the theory that an opened artery should be associated with reduced complications of CAD, interventional cardiologists began to preach that the only way to diagnose CAD was with an invasive angiogram[v]. Once an angiogram showed a narrowed coronary artery then a Percutaneous Coronary Intervention (PCI) or Angioplasty should be done to allow normal coronary flow[vi]. This should prevent MI or death. In 2007 a multicenter, randomized, controlled clinical trial to test this theory was performed[vii]. This study, and a long-term follow-up report also failed to show a benefit to interventional restoration of blood flow in the absence of an AMI. There are data that PCI is potentially beneficial when used to treat a patient with AMI, based on a change in understanding of the pathogenesis of AMI.

The clinical diagnosis of heart attack or Myocardial Infarction (MI) was initially synonymous with coronary thrombosis[viii] In the mid 20th concept was challenged by many authors[ix]. It was not until a very brave cardiology group showed that clot was in fact the cause of MI, that a completely new paradigm of treatment of MI – treating a clot in the artery responsible for the problem[x].

There are many other examples of a new look at an old problem which may result in a better understanding of a clinical condition and lead to markedly improved therapies.

In other situations, a new look may prove a therapy, that initially seemed to be beneficial, to in fact be harmful and actually not helpful to patients (often at high financial cost)[xi].

Observations such as these[xii] may lead patients and physicians to a sense of futility and angst. If there is so much medical reversal, how are we ever to know what to do? Here, I think, we need to realize that there is no certainty in almost anything and that we should go with our best assessment of the best available data. If something “new” comes up and overturns a dogma, then we should embrace the new knowledge and adjust our behavior accordingly. We should understand that in general those reporting in the literature are trying to do the best they can for their patients and the public in general. Sometimes what we thought was true isn’t. That’s when we might get into trouble.

Why Don’t Many People Like “The Patient Protection and Affordable Care Act” (PL 111-148) also known as “ObamaCare”?

In 2010, the Affordable Care Act was passed by the Congress and was signed into law by President Obama. The House, Senate and President were all Democrats.[i] Since then, a significant portion of the United State population has voiced disapproval of the act. Some of the opposition has been simply a partisan political party disagreement in basic approaches to government. The underlying premises of the law, improving the delivery of healthcare and making it available to the whole country are hard to argue against. Much of this bill had origins in the Republican law in Massachusetts, known as RomneyCare after the Republican Governor who proposed and shepherded health care reform[ii]. The passage of PL111-148 involved what was perceived as stampeding the bill through congress. With Senators Daschle and Kennedy no longer in the senate, the Democrats bypassed the possibility of a Republican filibuster, by using a maneuver called reconciliation or by changing the Senate Rules[iii]. One highly visible portion of the bill mandated that everyone have some form of insurance or pay a penalty[iv]. This was intended to ensure that insurance did, in fact, spread health care cost risks over the whole country. To allow people to have a marketplace for buying insurance, the bill encouraged states to establish purchasing cooperatives for individual insurance. This was to be accomplished through the establishment of government run “exchanges”. There were also many other aspects of the provision of healthcare that involved federal and state governments supervising or mandating (hopefully improving) various components of care.

Administrative problems surfaced as the roll out of the insurance exchanges began in 2013. Many of the buyers participating in the exchanges were those who did not have employer based or government sponsored insurance[v]. Despite a section[vi] of the bill that was supposed to simplify the language of insurance[vii], many of the various insurance options were difficult to read and understand. People didn’t appreciate the differences in coverage provided by the various levels of plans[viii]. Insurers were hesitant to support the exchanges, and often did not offer products on many of the state based exchanges. Many of those that did offered policies that covered care only through what are called “narrow networks” of physicians. This meant that at least a significant number of people who liked their doctors were not able to keep them[ix]. In 2016 it appeared that some of the problems associated with the functioning of the exchanges and insurance company participation were on their way towards resolution. A second major complaint against the bill was that it seemed to impose a number of governmental regulations/restrictions on some providers, especially health insurance companies. These entities had done some “bad things” in the past, in the name of business practices (maximization of profits). These included charging premiums for “pre-existing conditions” and putting arbitrary limits on how long the insurer was liable to provide payment for a patient condition. In addition, the practice of rescission was rampant, causing people who thought they were insured to be responsible for medical bills that they had believed were covered. In order to ensure that insurance would cover certain basic services, the Bill proposed a series of “Essential Health Benefits”. These included:

Essential Health Benefits in PL 111-1148

1. Ambulatory Services 6. Prescription Drugs
2. Emergency Services 7. Rehabilitative Services
3. Hospitalization 8. Laboratory Services
4. Care for Pregnancy, Maternity and NewBorn 9. Preventive and Wellness Care
5. Mental Health Care including Substance 10. Pediatric Care

There were things that were NOT included in the initial bill. Abortion was not included, nor was birth control specifically covered[x].

In addition, the bill limited the profits that insurers could realize. This was in the form of what was called a “Medical Loss Ratio”. For most insurers the MLR was pegged at 85%[xi].

The concept of spreading risk amongst the whole population by mandating that everyone in the country buy insurance (Individual Mandate) was immediately attacked as Congressional overreach. The Supreme Court got involved and eventually ruled that a special tax could be imposed by Congress, on those who elected/chose not to “play” in the health care insurance concept.

As the bill was being crafted, there was a significant amount of disinformation being promulgated. One of the worst pieces of misinformation that sought to discredit the bill was the concept of “Death Panels”. This term was used as a descriptor of the concept that insurers pay doctors or other health care professionals a fee for discussing with a patient what his/her wishes for end of life care. This would allow the discussion to be had while the person was in full command of his or her senses. Two women, Betsy McCaughey and Sarah Palin, fueled this misrepresentation of the spirit of the mandate to allow physicians to discuss end of life care, as “the government” supporting euthanasia. There was nothing in the bill to support that contention. In 1993 similar mischaracterizations of the Clinton “Health Security Act of 1993” was being proposed. The “Harry and Louise” advertisements misrepresented the tenor of the proposed health care plan and helped solidify opposition to the legislation[xii].

People also objected to allowing the Centers for Medicare and Medicaid Services to study ways of paying for and delivering care, which was proposed by the formation of the Centers for Medicare and Medicaid Innovation.

Almost all of the objections to the bill might be characterized as objections to government participation in the delivery of healthcare (payment, business practices, and provision of care). This was branded by many as “Socialism” and political posturing. It is even possible that some objected to Mr. Obama himself and did not want to support anything that he proposed[xiii]. Some objections were simply mischaracterization or misunderstanding of parts of the law.

A Follow-up on the Autopsy

This follow up on the Autopsy has data and suggestions for returning the autopsy to a significant role in medical education (both initial and continuing education of physicians and all other health professionals).

Pathologists have reported autopsy findings since before the 18th century. Autopsy findings contributed to major improvements in diagnosis in the North American Continent. In 1912, Richard Cabot, MD, from the Massachusetts General Hospital, reviewed the results of 3,000 autopsies and demonstrated that clinical diagnosis was frequently incorrect[i]. William Osler, MD, the author of one of the first comprehensive textbooks of internal medicine[ii] performed over 1,000 autopsies himself. It is said that a large portion of the knowledge he shared in his book was because of his experience at the autopsy table. Even after he stopped doing his own autopsies, Osler continued to attend autopsy organ review at Johns Hopkins because he still thought that the autopsy was important.

In the latter portion of the 20th century, the autopsy seemed to have taken a lesser place in the education of the practitioner of medicine. There may be at least three reasons for this downplaying of the autopsy:

  1. The autopsy takes time and specific skills to perform properly. Many physicians/pathologists believe that they have other, potentially more important (or remunerative) priorities
  2. There is the expectation that the clinical diagnosis, with the aid of “advanced imaging”, is sufficiently accurate to explain a patient’s illness
  3. In the era of “fee for service”, there is no third party payment for the performance of an autopsy. Thus, the patient’s family might be asked to pay for a post mortem examination

A corollary to these observations is that the autopsy is not always well done and the findings from an autopsy examination are not promptly relayed to the concerned physicians and family

There are data, which suggest that the rate of autopsies in hospital deaths was reasonably stable from the 1950’s through the early 1970’s[iii].

Reports since the beginning of the 21st century continue to show that the clinical diagnosis before death is incorrect in a significant number of cases[iv]. In 2015, an abstract from Denver, CO suggested that the cause of death determined on clinical grounds wasn’t completely correct in 70% of autopsied cases and it was markedly different from autopsy findings in as many as 35% of instances[v]

The precursor organization to The Joint Commission (TJC) stopped requiring a specific autopsy rate as a quality indicator in approximately 1972[vi]. The reason for this change in policy is not entirely clear, but there may be several explanations why this change occurred. One might have been the introduction of advanced imaging, beginning with the CT scan (described by Hounsfield in 1972). These techniques provided pictures that initially seemed to obviate the need for anatomic confirmation[vii]. However, there are multiple examples where the CT and MRI results are “wrong” in that they are not confirmed at surgery or autopsy. Some of these errors may be biases in the interpretation of a scan. A recent report showed an alarming level of missed diagnoses and “over diagnosis” in MRI evaluations[viii]. Results of studies like these should suggest to us that “advanced imaging” does not have all the answers and that some correlation/confirmation of diagnostic findings might be warranted.

Thus, as an NPR item in 2012 suggests, the autopsy would seem to provide information that should be of interest to both clinicians and public health officials[ix].

However, in the era of “Fee for Service”, insurers have taken a stance that they would/should not pay for the performance of an autopsy. One example of this policy was the implementation by Priority Health, a Michigan based Health Insurance provider. At its inception the company declared, “An autopsy is not medically necessary for the welfare of the patient; therefore, autopsies are not a covered benefit”. Interestingly there were NO references cited to support the policy[x].

The Joint Commission may not be likely to “require” a specific rate of autopsies, as they did in the 1970’s. One might postulate that there are too many “business considerations” relating to the requirement of a number/proportion of autopsies. Perhaps the most compelling reason is that there are now competing accrediting organizations that also do not require an autopsy, and if hospitals don’t want to have to pay for autopsies, they might simply switch to another less demanding accreditation organization[xi]. This would lead to a loss of revenue stream to TJC. Unfortunately this posture could potentially allow US hospitals to be subject to less strict oversight (and potentially reduced quality of care) than is currently the case. If the Centers for Medicare and Medicaid Services to require a certain percentage of autopsies be done on hospital deaths this argument may be overcome.

The cost of an autopsy is not inconsequential. If the cost were to be born by the family, without any other payment, cost might be prohibitive. However, the costs of having an autopsy done are, like most costs in medicine, not transparent. There are data that an autopsy would cost less than $5,000[xii]. A 2011 article published in the website Pro-publica suggests that in one survey of 8 states, “an autopsy costs about $1,275” [xiii]. An investment by hospital boards of only one half a million dollars to support quality through the autopsy would pay for between 200-400 autopsies a year. Certainly a hospital (or hospital board) that was deeply invested in care improvement could divert this amount to support the post mortem exam and demonstrate a commitment to quality in their institution.

The medical community could take a lead in quality improvement by asking our politicians to again ask certifying agencies to include some autopsy numbers as part of the “deeming”[xiv] process. If an autopsy standard were incorporated into the health care facility/provider inspection process, then it would again be part of the “checks and balances” along with other means of ensuring diagnostic accuracy. Several medical groups currently active including but not limited to: The American Medical Association, The American College of Physicians; The American College of Pathology and The Society to Improve Diagnosis in Medicine the could work on this initiative. Many other physicians, including George Lundberg, MD, Stephen Geller, MD, and Lee Goldman, MD have all lamented the fall of the autopsy. Now might be an opportune time to re-visit this issue and take political action.

A Tale of Three Autopsies

The Autopsy used to be the basis of almost all knowledge in Medicine. Sir William Osler was said to have personally done well over 1,000 autopsies before he became Chief of Medicine at Johns Hopkins in 1889. His experience in the morgue and the knowledge of anatomy and pathology that he gained there were among the bases of his historic textbook[1]. In the 1960s Autopsy Rounds on Thursday afternoons at Cook County Hospital were mandatory. Today, the autopsy is almost a relic. Several groups, including the Society to Improve Diagnosis in Medicine believes that the autopsy should be revived to help with learning. Recently, I have become aware of several instances in which the autopsy changed the diagnosis of cause of death for patients and their survivors.

This will be a post in 2 Parts: The first will tell stories of three patients who died and how the autopsy helped improve knowledge, diagnostic accuracy, and improved reporting of data. The second part will be on how the Autopsy has declined in frequency and how we might restore its use. My opinion is that the Autopsy is a central component of the end of life event. Its use should help our professionals grow, keep our data more accurate, and help families understand their loved one’s illness. It could perhaps help them improve their own health behaviors.

Part: the first – Stories and their implications:

Episode One:

An elderly woman with spinal stenosis and known aortic & mitral valve disease had been seeing her internist for shortness of breath (SOB) of about a year’s duration. In addition to obesity, she had a mildly complicated past history[2].

Her SOB was largely on exertion, but there were occasional otherwise unexplained exacerbations even at rest.

Over her last 2 months, she had reduced most of her normal activity because of the SOB and back pain. She became even more sedentary.

Her physical exam was essentially unrevealing[3].

An echocardiogram was reported to show mild AS and MR with a normal LVEF[4] and no wall motion abnormalities. There was mild LVH (LV wall thickness was 12mm)

Neither her internist nor cardiologist thought that her heart disease warranted intervention.

One morning her husband found her dead in bed.

The medical examiner was ready to rule the cause of death – Cardiac arrest due to complications of Aortic valve disease.

At the urging of a family friend, an autopsy WAS performed. It showed recurrent recent and remote pulmonary emboli and one large clot in the right main pulmonary artery. There were thrombi in the left femoral vein.

Without the autopsy the main cause of death would have gone undiagnosed, the death certificate would have been incorrect, and the vital statistics of her county and state would have missed something that may have warranted a public education intervention.

Episode 2:

A middle-aged man, of the “baby boomer” generation, who had been diagnosed with Bipolar Disorder, became increasingly confused one day. His wife took him to the local hospital where he was found to be obtunded with no localizing physical findings. His past history was remarkable for multiple episodes of mania and severe depression. He was not consistent with his medications. Lab testing showed severe hyponatremia, which was treated aggressively at the local hospital. A lithium level 2 days after admission was twice the lab reference for upper limit of therapeutic. His exam was otherwise unremarkable. He never regained consciousness and was transferred to a referral center. In the ICU, his blood chemistries normalized, but he never recovered consciousness. Spinal fluid analysis initially showed no abnormalities. After two months, a second spinal fluid analysis showed potentially malignant cells. No primary was ever found. After two months, life saving measures were tapered and he died.

An autopsy showed diffuse hepatocellular carcinoma and cerebral edema.

The diagnosis of liver cancer would never have been made without an autopsy and the “official cause of death” would have been incomplete

Unfortunately, no HCV testing was done.

Episode 3:

A middle-aged man with known bicuspid aortic valve disease with mild stenosis was brought to the Emergency Room late one Friday afternoon because of chest pain. Other than the early systolic ejection click and systolic murmur, the exam was unremarkable. There was no evidence of myocardial infarction or myocardial ischemia on ECG, blood testing or a myocardial scan. A CT of the chest was reported as normal. The ER was especially busy that day and the short-staffed ER doctors didn’t look at the CT themselves. The patient was sent home to see a cardiologist for workup in 2 days.

His wife says he died that night next to her in bed.

An autopsy was performed and the pathologist told the family that they should sue because he had a descending aortic dissection.

The autopsy was helpful in teaching the staff who cared for this man, because it emphasized the need to look at diagnostic tests or at least review them with the radiologist or pathologist.

In each of these episodes, the autopsy clearly changed the diagnosis as to the cause of death, making statistics more likely to be representative of “truth”. In each instance the autopsy was of comfort to the family. In each instance, the medical staff could have used the information from the autopsy as a learning opportunity, even encouraging them to re-read the literature (online textbooks such as Merck Manual, Up To Date, or others as well as some “original literature”).

Some families may be hesitant to request an autopsy, because it “might” be disrespectful to the loved one. The autopsy doesn’t hurt the deceased[5]. There are no real strictures against the autopsy in the major religions practiced in the US[6]. In spite of this, many families still plead religious constraints

Part two of this post, describing the demise of the autopsy will follow soon.

Why has respect for Medicine and Physicians largely evaporated?

Most, physicians choose to enter Medicine for more than “just” income opportunities. They are also motivated by altruism, and a desire to do good for the communities in which they served[i]. Physicians anticipated respect, which came from appropriately applying their knowledge and skills, as well as from knowing that both their peers and patients had confidence in them. In the late 1960’s and early 1970’s, physicians were respected and trusted. Surveys in this era suggested that 70% – 80% or more of Americans trusted or had confidence in medical leaders[ii]. In 1977 medicine was the most respected of American institutions. Today just over 35% feel similarly and medicine ranks sixth of seventeen institutions that were the subject of the surveys. This loss of respect for the profession of medicine likely is related to two facets.

Trust in American institutions has declined since the mid 1960’s, as many in the country became disenchanted with the progress of the war in Vietnam. In the first half of 1968, Martin Luther King, Jr. and Robert F. Kennedy were both assassinated. After these two deaths a general feeling of discontent seemed to overtake the country. This may have reached a boiling point when the 1968 Democratic National Convention, held in Chicago, was tarnished by large, loosely organized, protests occurring in Grant Park. Rioting after MLK’s assassination had already damaged large portions of Chicago and other cities[iii]. The DNC convention-related demonstrations were widely reported on TV and portrayed the city and its police in a negative light. Richard Nixon won the 1968 presidential election. In 1972, as he was running for a second term, the break-in at the Democratic National Headquarters in the Watergate complex in DC occurred. There followed a series of events, which eventually led to Nixon resigning, while facing the threat of impeachment for misuse of executive powers[iv]. The Vietnam War ended in 1975.Several commentators subsequently opined that the war was both poorly conceived and prosecuted. Many of these scandals were magnified by attempts by the perpetrators to cover up their activities

Public scrutiny of institutions such as occurred in the late 1960’s and early ‘70s had never been as intense. It continues. Whether the country has ever recovered from the loss of trust engendered by the Vietnam War and by President Nixon’s activities is not clear. Nonetheless, from the mid 1960’s to mid 1970’s there began a growing public disenchantment with the institutions that should be serving and protecting them.

In the period from the 1970’s to mid 80’s Medicine had a similar series of widely reported mis steps including unethical or unsafe behaviors. Consider the report in 1972, of the conduct of the Tuskegee syphilis study, which simply observed and withheld effective therapy for men with syphilis. This happened in spite of the discovery that penicillin was curative.[v]. In addition, as insurance became the dominant method of paying for health care, a part of the relationship between physician and patient began to unravel. When the Health Maintenance Organization concept became formalized in the early 1970s, patients became further separated from the payment for health care. Large numbers of the general public began to suspect physicians of “rationing” or “denying” care in order to save money for themselves and their HMO employers. While these events were occurring, patient advocate and attorney activities encouraged an environment where patients and physicians could potentially becoming adversaries. In addition, in 1984 a highly publicized death of a young student, Libby Zion, in New York, made the public more aware of the potential for fatal medical errors[vi]. Several years later, the National Academy published its seminal book, “To Err is Human”[vii], which was said to “break the silence that had surrounded medical errors, their frequency and consequences”. This led to greater public awareness of the limitations of medical practice.

The combination of publicity of medical misadventures, the interference of outside stakeholders with the physician-patient relationship and the evolution of a distrust of institutions in general, have contributed to the loss of stature and respect for a once proud and respected institution – the practice of medicine.

Does Insurance oversight of clinical practice improve either quality of care, or patient outcomes?

There appear to be no data to confirm this proposition[i],[ii].

I admit that I have a bias when it comes to the evaluation of quality of care and use of guidelines. I believe that measuring quality of care is close to impossible. Quality, as Justice Potter Stewart might have suggested, is almost always in the eye of the beholder. Nonetheless, we should try to come up with some agreed upon markers of quality. Otherwise, we will be without data and then, as Demming says, “just another person with an opinion”. I also believe that heterogeneity in the delivery of care for a single condition is often inappropriate. In general, use of guidelines will allow average practitioner help more patients more effectively.

Evidence Based Guidelines are, however, analogous to a magnetic compass which points to magnetic north, not true north. As long as the journey is going well and you don’t need help near the end of a journey, following the guidelines will most often help with decision-making. As you get nearer the pole and the journey isn’t going as easily as you had predicted, the compass, or the guidelines, may no longer be helpful. At the point when the patient hasn’t responded as had been predicted by the guidelines, specialist care is often invoked. At this point, a specialist/consultant may recommend variations from guidelines, driven now by clinical experience/judgment: the best assessment of evidence, other than that which drove the guidelines; consideration of the patient’s individual values and goals; as well as ethical and family considerations are appropriate.

Sometimes variations from guidelines suggest that utilizing a more expensive therapy may be appropriate. Sometimes using an “older” therapy that has generally been supplanted by “newer” therapies may be better for an individual patient. Not all patients will respond to “Guideline Driven Therapies” the way that had been predicted or hoped for. In these cases an expert is often asked to help with the therapy.

In patients covered by some Pharmacy Benefit Management (PBM) programs, there is often a “peer review” process that looks at a diagnosis and a therapy to see if they “match”. If they don’t, then the prescribing physician is often asked to justify the course. When the prescribing physician is an experienced, well-trained practitioner, who generally hasn’t misused the system, some of this oversight is onerous. Two examples come to mind:

One friend of mine, an experienced rheumatologist had been treating a middle-aged man employed as a general contractor with severe DJD of the knees with intraarticular hyaluronic acid injections on a six to nine month basis for over 5 years. With this therapy, the patient didn’t require more than occasional NSAIDs for comfort, thus avoiding opiates and knee replacement surgery, and was able to work without missing a day. While the therapy was included in the original Guidelines issued by the patient’s insurance company, the most recent edition rescinded approval for the use of hyaluronic acid due to equivocal evidence of efficacy based on a single, new meta-analysis. Because the therapy was not recognized in the revised guidelines, the rheumatologist was challenged by a physician reviewer (who happened to be a pediatric intensivist) working for the PBM. When the rheumatologist asked to discuss the issue with a rheumatologist or at least an adult internist, the pediatrician balked. Eventually, the therapy WAS approved, after about 90 minutes of discussions over multiple phone calls.

Another friend also discussed potential difficulties in getting an effective therapy approved in a complex patient. In this situation, a young woman with long QT syndrome who had been treated with diphenylhydantoin, a well recognized antiarrhythmic drug from the 1970’s to1980’s. The drug had controlled the patient’s symptoms in the past, and when it was stopped, the symptoms returned and were found to be related to the Long QT associated ventricular fibrillation. Other drugs may not have been effective, and when Dilantin was restarted the symptoms disappeared.

In both these instances, an experienced physician deviated from current Guidelines, because they suggested therapies that were thought to be outdated or were otherwise not applicable, even though in the individual patient they did work,. If PBMs could keep a database of physicians and their level of training, in addition to how often they deviated from usual therapies without good reason, they could avoid potentially unnecessary conflicts with physicians. This would save time and could save overall health care costs. In addition, time spent pleading with non-peer physicians could be better spent caring for more patients. This would likely improve physician satisfaction with practice. In addition, patients would likely be happier, being able to be seen more rapidly and not have to discuss insurance “interference” with therapy recommendations. Primary Care physicians would be happier because the specialist could see his/her patients sooner and likely be given better service as well.

Cook County’s Sweetened Beverage Tax of November 2016 – It’s A Matter of Choice!

In early November of 2016 the Cook County Board passed a one cent per ounce tax on sweetened beverages. Almost from the day the ordinance was passed, organizations from the beverage industry and small business have publicly opposed the tax. There were organized protests in front of the County Building on June 27, 2017. At the last minute, the Illinois Retail Merchants Association, which is affiliated with the Illinois Beverage Association, filed an appeal asking for a Temporary Restraining Order against collecting the tax.

As the battle lines between purveyors of Sweetened Beverages (SB) and the County government became drawn, one might question the wisdom of such a tax. The County position in favor of the tax was supported by every health related public interest organization. Sugar has been a part of dietary intake since the eighteenth century, but was used mostly as a “spice” until its production was more recently made easier and some cane sugar substitutes became readily available (including beet sugar). Like most spices, sugar has no documented intrinsic nutritional value. The nutritional labels on foods have no “recommended daily intake”, because the Food and Drug Administration hasn’t found one. However, several organizations worldwide have suggested that there is a level that should not be exceeded. They have suggested that a child of 7-10 years consume no more than 25 (20-30) gm daily[1]. The American Heart Association suggests that a woman take in approximately that amount, and that the average man take in no more than 36 gm.[2]

There have been multiple scientific reports that suggest increasing sugar intake is associated with obesity and its complications:

  • Diabetes
  • Hypertension
  • Heart Disease
  • Some Cancers
  • Arthritis

Thus, any initiative that will help dissuade people from consuming SB should help improve the public’s health. One estimate is that approximately a third of of the nation’s health care spending is related to complications of consumption of excess sugar.[3]

These observations would suggest that in addition to generating revenue by a tax, there would likely be a reduction of demand for sugar sweetened beverages. The reduction of demand should lead to enormous Public Health Benefits, potentially associated with a reduction in health care costs to the county upwards of $400,000,000.00 annually[4]. The cost reduction would likely take several years to realize, but should help decrease County costs over time that would result in a potential reduction in other taxes. One should understand that this type of tax is one of choice. Those who buy beverages that have added sugar or artificial sweeteners pay the tax. Those who substitute water, milk, or pure juices don’t pay it. Because it is a choice tax it is not inherently discriminatory. In fact, in one community the lower income residents had a greater decrease in SSB consumption than those with higher incomes, although in both income groups consumption decreased.

Overall, the Cook County SBT makes sense. Those selling these drinks claim that their business will be adversely affected. They will still make profits, perhaps a little less. This seems like a small price to pay for the potential public health benefits that disincentivizing SSB consumption should provide

Some thoughts on Health Care Legislation 2010 to 2017.

The PP – ACA (PL 111-148), or “Obamacare” had the term “Patient Protection” in it, because of what were perceived by many to be inequities forced on people by insurance companies. These included, but were not limited to:

  • Pre-existing condition exclusions
  • Rescission (the revocation, cancellation, or repeal of a law, order, or agreement.)
  • So Called “Usual, Customary and Reasonable” (UCR) Charges which had no basis in empiric data, which drove payments to physicians and others down.
  • Limited benefits (supposed to be corrected by defining “essential health benefits” (sect 1302 (b))[1]
Ambulatory patient services Prescription drugs
Emergency services Rehabilitative and habilitative services
Hospitalization Laboratory services
Maternity and newborn care Preventive and wellness services and chronic disease management
Mental Health and substance use disorder services, … Pediatric services, including oral and vision care
  • Driving up profits that were not then used to improve health, which was hopefully addressed by creating and defining a minimal Medical Loss Ratio[2]
  • Providing policies that included so much legal language that no one could understand them, and didn’t read them. A component (Section 2715) of the bill, that mandated insurers make policies readable and no more than 4 pages of font that was ≥ 12 points, was aimed at this practice.

In addition, insurance was being unevenly provided. If provision of “Insurance” is to even out exposure to risk, then everyone who may be at risk should be carrying insurance, and they should have it “all the time” not just when an emergency comes about. There were provisions in the bill that were designed to have insurance for health care be just that. These included a clause under the rubric of “shared responsibility” which was also called the “individual mandate” that said that every person in the country must have health insurance. In addition, the bill stated that employers should participate in insurance pools and provide insurance to employees (this could be in place of higher wages, as happened during WWII when wage and price freezes were circumvented by giving health insurance to employees). This was especially irksome, for several reasons, to many people.

If insurance was to pay for care for people who have a health related issue, the debate about whether access to health care is a “right” or a “privilege” has to be entertained and resolved. In addition, the discussion of remuneration of those who provide care has to be agreed upon.

The PP – ACA also had a number of provisions to help improve delivery of health care by encouraging investigations into quality improvement. There were also a series of taxes in the bill, predominantly on industries that made profits in the delivery of care, to help defray the costs.

There are currently two proposals for changing the way that health care is being provided under the current law: The House of Representatives has considered and on May 4, 2017 passed a bill to submit to the Senate called “The American Health Care Act of 2017” (HR 1628)[3] (AHCA). The Senate has received this bill and has then developed a bill, of its own, called “Better Care Reconciliation Act of 2017 (BCRA). The senate bill was released to the public on Thursday June 22; two weeks after the house bill had been given a second reading on June 8. The two proposals are not dissimilar.

The three health care proposals are very different in structure

Bill

Number of Pages in PDF

PP-ACA (PL 111-148) 906 in bill form
AHCA of 2017 (HR 1628) 132 in markup form
AHCA of 2015 (HR 2653) 195 in markup form
BCRA of 2017 (Reconciliation of HR 1628) 142 in markup form

The two 2017 Bills are remarkably similar. They repeal all of the taxes that were included in the PP-ACA to help defray the costs of implementing components of the bill. They change the ways that people can get help in buying insurance (neither bill explicitly mentions exchanges – the ways that states were supposed to be able to get a viable insurance marketplace) by changing subsidies to tax credits[4]. Both bills penalize any insurance vehicle that contains provisions for abortion (with few meaningful exceptions – “other than any abortion necessary to save the life of the mother or any abortion with respect to a pregnancy that is the result of an act of rape or incest”)

Both bills make major changes in the way that Title XIX of the Social Security Act (Medicaid) is funded and administered. In addition, both bills allow states to apply for waivers from almost all of the mandates (both in Medicaid, and other insurance initiatives) that are included in the Social Security Act[5]. There are several components of both bills that will make Medicaid expansion for patients other than pregnant women, CHIP, over 65 years, or otherwise eligible for Medicare, would be ended. These provisions would cut the number of people eligible for Medicaid and essentially make them uninsured – again.

The house bill has a version of the individual mandate[6], allowing insurers to charge 30% more for people who have let their insurance lapse for more than 63 days. It does, however, give people the option of getting insurance before 2018 or 2019, without being subject to the penalty. The senate on Monday, June 26, included their own version of the individual mandate by would requiring a waiting-period of six months for insurance to become effective, if a person hadn’t had insurance before.

Rolf McMillan Gunnar, MD, MACP, MACC 1/22/1926 – 3/18/2017 – An Appreciation.

Dr. Rolf M. Gunnar died after a battle with Cancer. The Chicago medical community and the world lost a compassionate, and brilliant man.

I met Dr. Gunnar when I was an intern at Cook County Hospital in 1966. My resident, Julio Ortiz, MD, learned of my passion for cardiology and so invited me to go with him on Friday afternoons to Cardiology/ECG/VCG conferences, at the Heart Center in the Durand Building. At the time, Julio and I were on the Northwestern service at “County”. Dr. Gunnar was on the U of I service, but more importantly was with John Tobin, of the Loyola service, the co-head of the Cardiology section. There were other luminaries in medicine surgery and other specialties at “County” and in the West Side Medical Center.

As I was finishing my medicine rotation, Dr. Gunnar stopped me one day in the cafeteria at Karl Meyer Hall and asked if I might want to be his fellow in shock research after my residency in medicine. I had a friend in Vancouver who had done shock work himself and because of him, shock became my over riding passion.

I outlined the reasons why I would have to leave Chicago for a couple of years: First, I would need to do a medical residency before becoming a Cardiology Fellow – Dr. Gunnar said, “Don’t worry, we’ll look after that. I can get you into the U of I program”; Secondly, my “green card” was only for one year, my internship, and so I would have to go back to Canada to renew it – Dr. Gunnar said, “Don’t worry, we’ll look after that”. There may have been a couple of other “Don’t worry, …’s”. So I stayed in Chicago to continue my training as an internist and a cardiologist. While I was doing my medicine residency, I contracted Tb from doing CPR on a patient at the West Side VA Hospital. That was before I had any health insurance, and certainly no unemployment insurance. When I told Dr. Gunnar that I wasn’t going to be able to leave my apartment to work and so would not have any income, again he said, “Don’t worry, we’ll look after that”, and he did.

By that time he had developed a great division of Cardiology at the U of I and Cook County Hospital. He brought Willard Harris, MD, a basic researcher who also did research into Systolic Time Intervals to help non invasively evaluate Left Ventricular Function. He hired John Naughton, MD who did research into exercise testing and training as well as Cardiac Rehabilitation. Dr. Gunnar had also brought Shahbudin Rahimtoola, MD as a general cardiologist and researcher and Kenneth Rosen, MD one of the first cardiologists to do intracardiac diagnostic studies (The “His Bundle Study”) to the Cook County section of Cardiology.

Dr. Gunnar left “County” and the U of I and went to Loyola in 1970. I wanted to follow him, but he asked me to stay at U of I and work with Ray Pietras, MD who became head of cardiology in the division that Dr. Gunnar had built. I stayed for 4 years. Then I went to Illinois Masonic Hospital to apply my skills as a shock researcher and intensivist. My career diverged from Dr. Gunnar’s then, but not his influence. I always kept a picture of him in my office, watching over everything I did. I never wanted to disappoint him! I like to think that he did watch over almost everything I did in medicine.

When I asked him for a recommendation for fellowship in the American College of Cardiology, he was supportive – after I made a contribution to the ACC Heart House development fund. He was always a little impish like that. Like many of the rest of us who were at his 90th birthday party in January, 2016, I have myriad stories about his sense of humor and his drive to make us all better.

Dr. Gunnar influenced many young people in cardiology and academic medicine. He was gender blind – many of his trainees were women in a time when women often couldn’t get academic training. He continued to fine tune his skills as an amazing teacher. He heard things on cardiac auscultation that almost no one else could hear. He claimed his hearing was more accurate than a phonocardiogram, because he knew that a phonocardiogram could be manipulated.

From his early days at County, he believed that Chicago could and should be a renowned center of medical research and training, as it had been in the early 20th century. He organized the Chicago Cardiology Group. Many of the first meetings were held at the Swedish Club of Chicago on North LaSalle St where, as a member, he was well known and respected. Subsequently the meetings moved to the Rush Professional Building, Suite 500. He had hoped that by getting the cardiologists and their fellows together there would be cross-fertilization of thought, and perhaps there would be development of multicenter studies done in Chicago institutions. Later, when he was Governor of the American College of Physicians for Illinois, he tried to get the Chiefs of Medicine together for breakfast meetings to discuss common problems both administrative and academic. Again, he tried to engender cooperation. When the Chicago Heart Association tried to establish the Inter Institutional Cardiovascular Center, Dr. Gunnar was an ardent supporter. I think that he was disappointed that members of the Chicago medical community couldn’t be as collegial and cooperative as they may have been when he was in practice with his father, Dr. Herman P. Gunnar. RMG told me a story about how he tried to set up a CCU at McNeil Hospital in the early 1960s, but the practicing physicians there didn’t want RMG “stealing” or treating their patients. I wonder whether this was not in fact a presage of what was to come, with physicians not trusting each other and not wanting to work together?

Dr. Rolf Gunnar loved medicine. After his internship at Cook County from 1949-1950, and after his military service in Korea, he practiced with his father, Herman P. Gunnar, until he went to Boston to train in Cardiology. After that he returned and again practiced with his father, doing Medicine and Cardiology at McNeil Hospital in Berwin, before he became full time at Cook County. He published at least 3 papers with his father in 1962 & 1963 and subsequently began researching with Cook County associates again. The first papers from Cook County were done in collaboration on with Rimgaudas Nemickas and John Sutton in 1964.

Dr. Gunnar was always open to trying to improve Cardiology in Chicago. Dr. Joseph V. Messer recounted a time when Dr. Gunnar was trying to recruit him to improve the practice of cardiology at the Hines VA hospital and brought Dr. Messer to Chicago for an interview. At the time he knew that Theodore Schwartz, MD was looking for a Chief of Cardiology at Rush. Dr. Messer came to Chicago to look at Dr. Gunnar’s VA position. Dr. Gunnar invited Drs. Messer and Schwartz join him for dinner. Even though Dr. Messer eventually went with Rush. Dr. Gunnar, I am sure, felt that he had done the right thing by getting Dr. Messer to come and help lead the Chicago cardiology community.

I was once taken aback to learn that such a compassionate, sensitive man was a Republican (it was just after the Goldwater era). I believe that he may have been the first to tell me something to the sense of, “If you aren’t a liberal when you’re young, you have no heart, but if you aren’t a middle-aged conservative, you have no head.”. Dr. Gunnar certainly had both a heart and a head.

What is Quality in Medicine? – It Isn’t Easy!

I remember quality once being referred to as a paraphrase of Justice Stewart Potter’s statement referring to pornography as , “something I can’t define, but, I’ll know it when I see it”. When applied to medicine, this type of definition is, unfortunately, completely unsatisfactory. Quality should be something that can be defined and measured. However, even today, quality is largely in the eye of the beholder. Some of the stakeholders who may have a unique perspective on what comprises medical quality include:

  • Physicians
  • Patients
  • Other caregivers (extenders)
  • Nurses
  • Families
  • Employers
  • System/Hospital Administrators.
  • Researchers and other Academics
  • Payers (Governmental or Private Insurers)

A patient may view quality in terms of the way he or she gets to see a provider including such factors as: ease of getting appointment, attitude of para professional staff, whether the physician or staff are on time (how much leeway is acceptable is defined by the individual), the provider’s manner and personality, among others. A physician, on the other hand, is likely to view quality in terms of his/her training (specialist or generalist), his use of scientific evidence as it is published, his knowledge and familiarity with the most recent innovations, and perhaps in some instances his outcomes. Most physicians have probably not been rigorous in keeping track of their individual outcomes, in spite of Feinstein’s admonition to keep such records[1] A third group, outside bodies such as the federal government’s Centers for Medicare and Medicaid Services (CMS), or the Joint Commission (JC – previously the Joint Commission on Accreditation of Healthcare Organizations – JCAHO) often look at individual processes (drugs, counseling, and some procedures) that are done for specific conditions (often called by hospital personnel as “core measures”). Nurses often view quality as how promptly patients are seen and how their complaints are addressed. They always have an opinion on the quality of care provided by physicians, hospitals and other providers. It has been my experience that in the short run, nurses are more often “spot on” than not.

These, often subjective, measures can be quantified and made comparable between organizations and providers. One of the early attempts at defining quality was proposed by Avedis Donabedian in his construct that Quality was related to 1.) Structure (physical plant, institutional culture, and others); 2.) Process (what was delivered/performed) and 3.) Outcomes (mortality, morbidity, quality of life)[2],[3].

Q = S*P*O

The Institute of Medicine, in 2001defined six domains of an effective health care system, which is a surrogate for quality: Safety, Effectiveness, Patient Centricity, Timeliness, Efficiency and Equity[4].

As a physician, I have often been asked about the quality of another physician’s or surgeon’s practice. I often give an answer, but have become increasingly uneasy about the empiric basis of my recommendation. I almost never know a surgeon’s mortality rates (early or late), infection rates, or even his/her long-term efficacy rates. What I do know is how I think her/his judgment seems to be like (how often it improves my own judgment/recommendation), her/his personality (how we get along), what others of my compatriots seem to think, and whether he has had more than rare run ins with the hospital staff quality/practice review committees. My own patients’ encounters with the other physician/surgeon make up a small portion of his/her patient experience and as such may be biased either in favor or against that practitioner. I would like to think that my assessment of competence and quality of another doctor is valid, but I really have no easily available robust, concrete basis upon which to base my opinions

Who else is looking at quality and quality measures?

There are many groups looking at some measure of hospital or practitioner quality. For hospitals, the Joint Commission has its ORYX process measure tool; the CMS has its “Hospital Compare” data base[5], which provides information on utilization of process measures and outcomes such as mortality, 30 day readmission rate as well as some cost measures – but these are only for some clinical conditions (Acute Myocardial Infarction (heart attack), Congestive Heart Failure (CHF), pneumonia and Surgical Infection). There several coalitions of purchasers of healthcare (often employer groups) that look at their measures of quality: The Leapfrog group[6], a business purchasing group, just released results of a survey of quality metrics for approximately 1,200 hospitals,[7]. Some of the data on these measures were from publicly available sources and some from questionnaires filled out by some branch of the many of the hospitals. When a group of hospitals “failed” the leapfrog card they immediately questioned the methodology [8] . Many lay publications (Consumer Reports adn US News and World Reports among others) also have their own construct of what they call quality.

it would be ideal if many of the at least 9 stakeholder groups that look at quality could agree on a standard set of measures that may be revised periodically (but not too often). Thus, physicians, hospitals/systems, and other providers could keep a single series of quality measures that would satisfy the myriad people who want to report and depend on reports for making judgments on whom to use as a referral. Some groups such as the American Heart Association (through their Get with the Guidelines program [9] for some heart conditions, The American Board of Internal Medicine (with its Maintenance of  Certification) among others are trying to standardize process measures. If these are adequate, then other groups (like CMS and state licensing boards) should be able to incorporate satisfaction of these measures into their own requirements without “tweaking” them, which often leads to redundancy and increasing difficulty in keeping up with reporting.
