Ophthalmology versus Psychiatry Part 2.




Spoiler Alert: Ophthalmology always wins!

I was driving home last Friday night and for several minutes it seemed like there was a bug in my right eye.  I did the upper lid over lower lid trick a couple of times and that didn't work so I pulled over and tried to rinse it out with artificial tears.  No change at all with that maneuver and then I started to see familiar floaters and small black dots in my visual field but only on the right.  I had the exact same symptoms a year ago that led to a diagnosis of a vitreous detachment with no retinal problems.  Later that night I started to see flashing halos in the upper right visual field.  I got in to see an optometrist through my health plan and was referred immediately to a vitreous and retinal specialist today.  At a about 2PM today, I had a laser surgery procedure to fix a small retinal tear in the periphery of my right retina.

The specialist explained pathophysiology, the rationale and the expected success rate.  There is age-dependent liquefaction of the vitreous humor and in that process it can pull away from the retina.  That process can be benign like it was for me a year ago or it can lead to a "traction-event" on the retina and cause a tear.  The main reason for the laser surgery is to spot weld the tear by forming a photcoagulation scar where the laser hits and prevent a more extensive tear that could require open surgery of the eye and the risk of infection and further vision loss.  The decision for the laser surgery was an easy one, especially because I have known many people who required variations of the open surgery.  I sat in an ophthalmology exam chair with my head in a fixed position.  This video illustrates the exact procedure that I underwent today.  The laser light was green and at the end of the procedure I was completely blind in the eye for about 10 minutes and then transitioned to a violet vision and then back to normal.  This phenomenon is cause by saturation of the photoreceptors by laser light.  The procedure I underwent was much faster with repeated pulses of the laser.  If I had to estimate, I would say about 150-200 pulses of light were used.  The specialist kept me posted: "30% done.... 50% done, etc)" and also coached me on how I was doing focused on the extreme limits of my visual field.    

I had some observations about ophthalmology and orthopedic surgery last year and this year is no different.  First, I am amazed at how many of these vitreous retina specialists exist across the country.  Given my previous estimate of the total number of ophthalmologists and the numbers of people that they treat,  the distribution must be very good across the country.  Their services are certainly in demand.  Retinal and vitreous disease is clearly an age related problem.  There were 15 people in the waiting area and there was one person younger than me.  Most were considerably older and many were there to get injections to slow the progression of macular degeneration.

I am no stranger to ophthalmologists.  When I was in the 8th grade I shot myself in the eye with a BB gun and have had appointments every year to follow up on that injury.  That has also allowed me to follow the way that ophthalmologists practice.  Back in the 1960 to 1980s they did everything.  They started out with visual acuity tests, then visual fields, the intracranial pressure by tonometry and eventually the slit lamp approach.  They did the entire refraction and tried to get the visual acuity as good as possible. They proceeded to the slit lamp exam and at some point started doing retinal exams using hand held lenses and lens in conjunction with the slit lamp.  If an ophthalmologist was really flying and had a patient who was able to  cooperate - it might be possible to get all of this done in 20-25 minutes.

Things have changed drastically since that time.  I was roomed by a medical assistant who recorded the history and  took my vital signs.  In Room 2, I saw another medical assistant who took additional history, cursory social and family history (only eye diseases and diabetes in parents and siblings) and a cursory review of systems (have you had a heart attack or stroke? do you have chest pain today?).  She did visual acuity, visual fields by confrontation, and ocular motility and recorded it in the chart.  She did a slit lamp exam.  She measured intraocular pressure by some kind of digital hand held tonometer that I had never seen before.  She got my eyeglass prescription off the new lenses and did not need to do a refraction.  In Room 3, I was introduced to a scribe who told me that she would be taking notes for the specialist.  She set up twin displays with the EHR spread across.  The specialist walked in and performed indirect ophthalmoscopy by both slit lamp and standing hand held lenses.  He told me that I had a retinal tear and we discussed the surgery.  The scribe reminded him how it needed to be worded in the chart and how she was going to record it.  I electronically signed the consent form.  In Room 4, I saw a person who only did retinal scans with a blue light.  Finally in Room 5, the laser procedure was done.

This was a significant display of efficiency in terms of division of labor with a sole focus on problems related to the eye.  The social history is not that important in this case - they were only interested in marital status, offspring, and occupation.  They were not really interested in a review of systems other than a more detailed review of ocular symptoms - including my history of the BB gun injury.  They efficiently proceeded to laser my torn retina (at about the 45 minutes mark) and if the quoted statistics were correct - greatly reduce the likelihood or a major retinal tear and the need to open surgery or in the very worst case partial or complete blindness.      

Unfortunately in psychiatry we have nothing like this.  I am still doing what I have done for the past 30 years - an obsessive 240 plus point interview that included a detailed history.  My medical history, review of systems, social and family histories are all comprehensive and customized for the situation.  If I want vital signs or some examination - I have to do it myself.  In some clinics I can get checklists - but despite all of the hype about collaborative care or measurement based psychiatry those rating scales are a poor excuse for detailed questions about the problem.  The people who believe they are actually using quantitative metrics to measure care with these scales are fooling themselves.  In order to make up for the stunning lack of efficiency in psychiatric practice we have the workarounds of more and more prescribers - all asking their own questions and making their own diagnoses or we have the collaborative care psychiatrist advising primary care physicians on how to treat their patients based on rating scale scores or the questions of those physicians.

The other limiting factor is the lack of value assigned to the psychiatric evaluation.  I have not seen the bill for laser eye surgery - but I can speculate that it will be many times what I am paid for a comprehensive evaluation in roughly the same period of time that it took to diagnose and repair my retinal tear.  With the division of labor, the ophthalmologist was seeing 7-8 times as many patients in an hour than I can see.

To me that is both the most positive aspect of clinical psychiatry, but also its downfall.  Psychiatry is too complicated to commoditize.  Don't get me wrong - it happens all of the time.  Very few psychiatrists who are not in private practice have the luxury of talking with people for an hour.  That makes patient experiences highly variable.  We have to find a model that takes us out of the 1970s but also provides more clear cut results.  Ophthalmology has clearly been able to do that.  Science and treatment in medicine is better with precise measurement.  There is nothing about rating scales that I would call precise.

With my retina and vitreous problems I have come to another conclusion.  Training in Geriatric Psychiatry is designed to increase sensitivity to ageism and and biases against the elderly.  I have had plenty of that training.  Now that I am technically a geriatric person myself, I can speak with authority -  aging is an inescapable disease.  I hope someday there is a better solution.

But that is a topic for another post.

Psychotherapy Has No Image Problem - Psychotherapy Has a Managed Care Problem

There was an opinion piece in the New York Times a few days ago entitled "Psychotherapy's Image Problem".  The author goes on to suggest that despite empirical evidence of effectiveness and a recent study showing a patient preference for psychotherapy - it appears to be in decline.  He jumps to the conclusion that this is due to an image problem, namely that primary care physicians, insurers, and therapists are unaware of the empirical data.  That leads to a lack of referrals and for some therapists use of therapies that are not evidence based - further degrading the field.  He implicates Big Pharma in promoting the image of medications and that the evidence base for medication has been marketed better.  He implicates the American Psychiatric Association in promoting medications and suggests that the guidelines are biased against psychotherapies.

I am surprised how much discussion this post has received as though the contention of the author is accurate.  Psychotherapy has no image problem as evidenced by one the references he cites about the fact that most patients prefer it.  It wasn't that long ago that the famous psychotherapy journal Consumer Reports surveyed people and concluded that not only were psychotherapy services preferred, they were found as tremendously helpful by the majority of people who used them.  That study was not scientifically rigorous but certainly was effective from a public relations standpoint.

The idea that psychiatry is promoting drugs over psychotherapy seems erroneous to me.  The APA Guidelines certainly suggest psychotherapy as first line treatments and treatments that are part of selecting a therapeutic approach to the patient's problems.   Psychopharmacology is also covered and in many cases there are significant qualifications with the psychopharmacology. Further there are a number of psychiatrists who lecture around the country who are strong advocates for what are primarily psychotherapeutic approaches to significant disorders like borderline personality disorder and obsessive compulsive disorder.  Psychiatrists have also been leaders in the field of psychotherapy of severe psychiatric disorders and have been actively involved in that field for decades.   Even psychopharmacology seminars include decision points for psychotherapy either as an alternate modality to pharmacological approaches or a complementary one.  What is omitted from the arguments against psychiatry is that many payers do not reimburse psychiatrists for doing psychotherapy.

The author's action plan to politically promote the idea that psychotherapy is evidence based and deserves more utilization is doomed to fail because the premises of his argument are inaccurate.  There is no image problem based on psychiatry - if anything the image is enhanced.  There is definitely a lack of knowledge about psychotherapy by primary care physicians and it is likely that is a permanent deficit.  Primary care physicians don't have the time, energy, or inclination to learn about psychotherapy.  In many cases they have therapists in their clinic and just refer any potential mental health problems to those therapists.  In other cases, the health plan that primary care physicians work for has an algorithm that tells them to give the patient a 2 minute depression rating scale and prescribe them an antidepressant or an anxiolytic.

And that is the real problem here.  Psychotherapists just like psychiatrists are completely marginalized by managed care and business tactics.  If you are a managed care company, why worry about insisting that therapists send you detailed treatment plans and notes every 5 visits for a maximum of 20 visits per year when you can just eliminate them and suggest that you are providing high quality services for depression and anxiety by following rating scale scores and having your primary care physicians prescribe antidepressants?.  The primary care physicians don't even have to worry if the diagnosis is accurate anymore.  The PHQ-9 score IS the diagnosis.  Managed care tactics have decimated psychiatric services and psychotherapy for the last 20 years.

It has nothing to do with the image of psychotherapy.  It has to do with big business and their friends in government rolling over professionals and claiming that they know more than those professionals.  If you really want evidence based - they can make up a lot of it.  Like the equation:

rating scale + antidepressants = quality

If I am right about the real cause of the decreased provision of psychotherapy, the best political strategy is to expose managed care and remember that current politicians and at least one federal agency are strong supporters of managed care.
