I read “Of Two Minds” by anthropologist Tanya Luhrmann on
the schism in American psychiatry between “biomedical” and psychodynamic
schools of practice in US psychiatry. It was recommended by Crystal McGuire (
@moonrise1014 ) on Twitter. “Biomedical”
in the book refers to the model of making a diagnosis and offering the
indicated treatment – usually medication but also can refer to a therapist (like
the rest of medicine) but not covered in the book is how it evolved into a
biopsychosocial model which also focussed on psychosocial aspects of the case
in a broader formulation or that the biomedical model was often combined with medical
humanism inspired by Osler and Hippocrates – “better to know the person with
the disease than the disease”. Psychodynamic psychiatry is a therapy-based
approach involving many regular sessions and trying to understand the reasons
for the patient’s problems using a psychodynamic model. An interesting book let
down by loaded arguments in the final chapter that ignores its strengths in
describing the practices of American psychiatry particularly in the 90s and earlier.
The author caught the period of dramatic change brought on by health insurance
companies adopting managed care practices that drastically reduced costs especially
in mental health. This accelerated the decline of psychodynamic psychiatry as
health insurance companies increasingly refused to pay for psychodynamic
therapy for outpatients and especially inpatients.
There appears to have been a “two-hit” knock to the once
dominant psychodynamic school in US psychiatry (I’m referring to the psychiatry
profession not the wider mental health provider system nor to other professions
such as non-medical psychotherapists). As a Brit it’s interesting to see the
large differences with practice in the UK compared to the US. Szasz in his
article criticising the “myth” of mental illness criticised the overreach of
psychiatry claiming to be able to fix every social problem. It seems he was
referring to psychodynamic psychiatry for this issue but most of his other criticisms
are aimed at “biomedical” psychiatry.
The first hit to psychodynamic psychiatry was a multiple
assault. Antipsychiatry criticisms of diagnosis – such as the now discredited
Rosenhan study- and the conventional psychiatry study demonstrating New York
psychiatrists had an idiosyncratic view of schizophrenia compared to European
psychiatrists led to demands for a better diagnostic system with higher degrees
of agreement between clinicians (inter-rater reliability). This ended up in the
DSM American diagnostic system moving from one based on psychodynamic theories
to one less based on theory and being more descriptive with a focus on
increased inter-rater reliability. Another issue was that some clinical
problems such as severe depression, schizophrenia or bipolar disorder just did
not respond well to psychodynamic therapy if not given medication first. (The
famous Osheroff case where the psychodynamic psychiatrists persisted with
therapy for agitated depression instead of trying medication set an important
clinical precedent). The development of effective medication for psychiatric
problems in the 50s eventually led to “biomedical” psychiatry getting an
increasing role in care provision and with the multiple factors described plus
the hubristic nature of psychodynamic psychiatry resulted in “biomedical”
psychiatry gaining dominance. There was still co-existence between the two
schools. Further developments in medications that were easier to take (such as
SSRI antidepressants) and increased ability to measure brain function favoured
the “biomedical” model.
The next major hit came from managed care and cost-cutting
in the 90s. They demanded evidence of effectiveness based on research using
diagnosis and other shared characteristics with large numbers of patients in
each study before agreeing to spend on treatments especially expensive treatments
like psychodynamic psychiatry (seeing a psychiatrist from once to four times
weekly for a 50-minute hour is much more expensive than seeing a psychiatrist
for 15-30 minutes every few months in the “biomedical” model). Psychodynamic
inpatient care lasting several months of intensive therapy was much more
expensive than treating with medication which is often effective within weeks
(though some conditions respond better to psychodynamic approaches and others
better to “biomedical” approaches). Unable to provide the evidence to justify
the increased expense led to massive cuts in health insurance pay-outs for
psychodynamic psychiatry.
So, what are the lessons for any type of mental health core
model? Note this isn’t discussion about the effectiveness of psychodynamic
therapy. This is about psychiatrists who used the psychodynamic model in the US
up until the 90s. I’m not saying that psychoanalytic treatments don’t’ help
people nor that psychoanalytic therapy has no strengths or good points.
The main lesion is hubris leads to downfall. This
hubris led to several problems
·
Blaming everything else but the treatment model
when it didn’t work for an individual patient – for example saying the doctor was
too scared to get emotionally close to the patient
·
A blindness to professional arrogance –
everything was explained away by an opinion reinforced by authority that was
unchallengeable. If the resident was later for morning meeting they would be
told by the psychoanalytic supervisor it wasn’t because they had only 3 hours
sleep during on call it was because they unconsciously did not want to attend
·
Antipathy towards other alternative models. The
use of medication was regarded as a crutch or an addiction. They ignored that
some patients needed medication to improve their mental state (and could then
benefit from psychotherapy if they chose)
·
Lack of interest in more modern research methods
and preferring older methods such as case studies meant that when managed care
came in demanding evidence using modern research methods they had nothing to
defend their methods from the cost-cutting axe. The lesson for all models of
care is that they must be aware of what type of information those who purchase
services want and provide it.
·
Unable to see what was helpful for seeing small
numbers of private practice patients – often from similar affluent backgrounds
to the psychiatrists – would not work for public hospital patients. These were
in great numbers, poor and suffered from additional multiple social adversities.
Arguably both types of psychiatry ignored the need for interventions acting on
the social realities of these patients – though biopsychosocial psychiatry
practised in multidisciplinary teams is better at doing so.
