Vampires and Urban Legends: Teaching Residents about Healthcare Costs

24 05 2011

This past weekend, I gave a talk at the Committee of Interns and Residents, the largest housestaff union in the United States.  The most inspiring moment of the meeting that I witnessed were the 2 standing ovations earned by Dr. Koffler for advocating for residents to get paid in 1936 (her first paycheck was 15 dollars a month!).   How could I follow that…especially with a talk on how to train cost-conscious physicians?   Those who know my work well may even wonder how I got invited to talk about this.  Well, earlier this December, I wrote on the blog about my holiday wish list for medical education and #2 was a curriculum on cost conscious practice for medical trainees.   In addition to lack of a formal curriculum, there were several other barriers on teaching residents how to practice cost-conscious medicine that I discussed.

  • Faculty are not trained.  The largest barrier of course is that faculty don’t know how to do this.  A study in Journal of Hospital Medicine showed that faculty physicians could not identify what things cost.
  • No one knows what the cost of anything is.  Because each hospital negotiates its own prices with suppliers, it is very difficult for residents to know how much things cost.  In trying to find out how much your hospital charges for various tests, you may end up on a wild goose chase until you find the helpful person who may or may not even be in your state!
  • Bad systems promote costly workarounds.  Most of the time, residents are too concerned that they won’t be able to get a test or worse, it will delay a patient’s discharge.  The system is set up to order the test even if the attending thinks about it.  Some of our own data shows that interns learn during internship to misrepresent tests as urgent to get the job done.
  • Rumors and hospital legends spread quickly.  The highly connected residency program can actually spread rumors about how much things cost or give rise to urban legends when patients actually pay and don’t pay.
  • Underordering, not overordering, is penalized.  Due to the highly litiginous environment, most attendings encourage residents to err on the side of getting a test since the biggest fear we all have is of missing the ‘can’t miss’ diagnosis.  More reasons doctors over-order tests here.

So what can we do to teach residents about cost-conscious practice?  Well here are just a few of the things we can do..

  • Empower residents to find out how much their hospital charges for things.  As I said at the conference, we may need to start a support group for those that start down this daunting path – but it is the first step to understanding how to control costs.  Starting with senior leadership could be helpful – after all, how many C-suite leaders would not want to find out how to teach residents to control their costs? There is also a related movement to improve price transparency for patients.
  • Show residents how much they spend.  At least in the case of daily phlebotomy, a recent study dubbed “Surgical Vampires” (due to the daily blood draws ordered by the surgical interns) highlighted that letting residents know how much things cost actually reduced the cost of lab ordering per patient and resulted in 50,000 dollars saved over 11 weeks!  Studies with electronic health records at the point of care show even greater results!
  • Use unbiased resources that promote better cost-effective decisions.  Specialty societies like the American College of Physicians and the American College of Radiology are now starting to create guidelines that encourage cost-effective practice through more judicious use of imaging or other therapeutic modalities.   The popular 4 dollar list for medications is another example.
  • Incorporate discussions of costs into routine educational conferences.  At Harvard, one chief resident started a Hospital Bill Morning Report for the residents to review what a patient bill is like.  In our medical student lectures on radiology, the costs of the tests are also now discussed.
  • Educate patients that less is sometimes more.  Letting patients know about the risks of overordering tests- specifically workups of incidentalomas and pseudodisease may be helpful in explaining your new approach to cost-conscious medicine.   The pushback from patients may be the fear of rationing,  which is of course irrational since it already occurs.  A helpful summary for patients on high value cost conscious medicine appeared in Annals of Internal Medicine.
As with all things, there is the potential for unintended consequences in teaching cost-conscious medicine.  The most egregious of which would be to hide behind the veil of practicing cost-conscious medicine in order to shirk work and avoid getting an indicated test when needed.   This is especially important to watch out for as burnout sets in late in the academic year.  So, as we resist our inner vampire urge to order blood tests and uncover hospital urban legends and myths about healthcare costs, its equally important not to morph into the haphazard and dangerous cost-cutting monsters that we all fear most.

Healthcare Horrors: Needles, Medical Studentitis & Other Medical Phobias

3 11 2010

Every Halloween, I take note of some of the most infamous Doctor costumes, ranging from the mad scientist who created Frankenstein to Dr. Jekyll and Mr. Hyde.  Even if you don’t dress up as a doctor, there’s enough medical paraphernalia that contributes to costumes including all that medical gauze for the perfect mummy costume, the skeleton head for your porch, or the fake blood for the perfect vampire or zombie.  This does beg the question, what is it about doctors and healthcare that is scary?  As it turns out, fear of doctors and healthcare is very common.  Here is a short rundown of the more common healthcare-associated phobias.

  • Iatrophobia is a fear of doctors.  Interestingly, these phobias are actually types of social phobias in which the afflicted is afraid of interacting with the doctor, discussing their personal illness, or being examined.  Some suggest that ‘white coat syndrome’ or higher blood pressure in the doctor’s office is part of this syndrome.  
  • Dentophobia is the fear of dental care or dental procedures.  Unlike iatrophobia, this is quite common and some sources cite estimates as high as 75% of Americans suffer from some form of ‘dental fear’. Some suggest this is actually a variant of post-traumatic stress disorder due to the pain associated with a prior dental procedure.  Not surprisingly, the dentist’s professional demeanor is also important.  Anyone scared of Willy Wonka’s dentist dad in Tim Burton’s Charlie and the Chocolate factory?
  • Nosocomephobia is fear of going to the hospital, which is either related to fear of death or could also be related to fear of contracting illness or disease (germophobia initially described in JAMA in 1910) and may be a variation on obsessive-compulsive disorder. Of course, it is important to distinguish this pathological fear from normal concern since hospitals are reservoirs for germs and disease and hospital associated infections are on the rise
  • Pharmacophobia is the fear of taking medicine, which is often related to fear of rare side effects due to a medication.  This can sometimes manifest itself as medication ‘noncompliance’, which doctors often assume patients are intentionally not following directions.  It is also often associated with prior adverse drug events.  Perhaps the best known pharmacophobia is currently manifest as the fear of vaccines in which it is not the fear of the needle (see below) but the fear the risks of vaccination like autism or that the flu shot causes the flu.
  • Needle phobia is a very common phobia.  Some estimates say at least 10% of Americans are trypanophobic, and are likely to faint during a needle stick.  This may even be an underestimate since those with needle phobia are not likely to seek medical care.  This is a very serious phobia since needle phobia is characterized by very low blood pressure and shock when presented with needles, and there have been reports of patient deaths.  Unfortunately, people with needle phobia often avoid recommended vaccinations and blood tests, placing them at higher risk of illness.
  • Nosophobia is the fear of contracting disease.  Perhaps the most classic example of this occurs in medical students (typically in their second year) who believe they or others around them are suffering from the symptoms of the diseases they study.  Medicalstudentitis was reported as early as 1964, and it is still alive and well.  One study estimated 80% of students suffered from this and a Facebook support group even claims 1000 members.  Nosophobia can also manifest itself in patients who spend a lot of time online searching for causes of their symptoms.  Cyberchondria is a type of nosophobia the unfounded concern that common symptoms are harbingers of serious disease due to online searching.

While these phobias may sound harmless, exaggerated or silly, it is actually important to identify people with these phobias and help them seek professional treatment early.  Patients with healthcare phobias are likely to avoid seeking care for actual symptoms which places them at higher risk of morbidity and mortality.  Now, that’s a scary thought!

Reviving Case Reports: Chasing Zebras or Solving Mysteries?

31 08 2010

I am teaching a new course this week entitled “Turning your Clinical Cases into Scholarly Work.”  I hope to draw on my own experiences through the years mentoring students and residents in writing up several clinical cases, but also in making diagnoses.  In preparing for this course, I have also learned quite a bit about the controversy surrounding case reports and the challenges that they face in today’s healthcare system. 

Unfortunately, case reports have fallen out of vogue.  Many journals no longer accept case reports or they have relegated them to the 2nd class ‘online’ only publication since they are often not highly cited and lead to a lower journal impact factor.  Critics of case reports actually say they overemphasize the unusual at the expense of the ordinary and are not evidence-based.  Furthermore, in today’s era of cost consciousness medicine, chasing ‘zebras’ or unique diagnosis is often frowned upon due to the potential for inappropriate or overuse of tests, with the possible unintended consequences of working up incidentilomas

Despite these concerns, case reports have had a major impact on the discovery of new diseases, mechanisms of disease and even drug therapies.  The first cases of AIDS were reported as case reports.  Side effects of drugs are often discovered through case reports and can lead to changes clinical practice (MRI contrast and nephrogenic systemic fibrosis) to prevent harm.  Cases reporting potentially desired side effects can also prompt accidental discovery of new drugs that can change quality of life for many people, as is the case with Viagra

So, how can we promote the art of case reports without creating zebra chasers who drive up healthcare costs?  Well, the key may lie in Sherlock Holmes.  Medicine is often compared to detective work and it is well known that Sherlock Holmes used the power of observation to make informed deduction.  While Holmes was a fictional character, the invention of Sir Arthur Conan Doyle (a doctor turned writer), he was modeled after Dr. Joseph Bell, Doyle’s former physician-mentor.  To get his trainees interested in observation, Dr. Bell used the power of observation to deduce mundane things like occupation and recent activity in passersby.  In essence, the clues to making the diagnosis lie in careful understanding of the patient’s story and observation of the physical cues.    

Unfortunately, the powers of observation are declining these days due to the ease of ordering CT scans without thinking about a patient.  Fear of malpractice also drives the use of diagnostic testing over trusting one’s self.  To make matters worse, diagnostic tests are financially rewarded, while thinking about the right test to order to make the diagnosis is not.  If the art of diagnosis were more handsomely rewarded, more hospitals would actually have a “Department of Diagnostic Medicine” led by their own version of Dr. House (who is based on Holmes incidentally …and Chasing Zebras was considered as a title of the show).  As stated by Rapezzi and colleagues…

Current trend towards mass use of sophisticated diagnostic tools in routine practice—accompanied by a blind faith in technology and predefined diagnostic algorithms—is threatening to kill off the science and art of clinical reasoning. Besides burning a lot of public and private money to make diagnostic work rather superficial, doctors also risk losing the intellectual pleasure that comes from careful diagnostic reasoning.

So, in considering how to revive case reports and the art of diagnosis, its worth revisiting lessons dating back to the old adages that been used to teach generations of doctors before the proliferation of imaging.  While each of these rules has its faults, they represent a return to thinking about the diagnosis.   If only it was only as simple as, “It’s elementary, my dear Watson”…   

Occam’s Razor – “entities must not be multiplied beyond necessity” refers to the thought there is usually one unifying diagnosis.  The term razor is used to highlight shaving away unnecessary assumptions to get to simplest explanation. 

Hickam’s dictum – “Patients can have as many diseases as they well please” The counterfactual to Occam’s razor is credited to John Hickam, MD who highlights that it is statistically more likely for a patient to have several common diseases explaining a constellation of symptoms rather than a rare zebra.  The best example of this is Saint’s triad which consists of gallstones, hiatal hernia, and diverticulosis which don’t have anything to do with each other other than they are often common in patients.

Pasteur’s dictum  - ‘chance favors only the prepared mind’  This refers to the fact that to make the ‘leap’ of discovery, one must have the knowledge & skills to be able to make the connection.  In other words, you cannot find an interesting case if you are not reading and know what to look for.

Sutton’s law- First, consider the obvious.  In other words, conduct the test which will confirm (or rule out) the most likely diagnosis.  This phrase is named for bank robber Willie Sutton, who when asked why he robbed banks supposedly answered “because that’s where the money is.”
