Evidence-based practice & education (Part 3)
"I feared that my brain was actually heating up and might explode. I visualized brain matter flying all over the room, splattering the walls. Whenever I sat at a desk and tried to read, I caught myself putting my hands up to either side of my head, trying to hold it all in."
Elyn Saks had had bizarre thoughts and hallucinations since childhood. At 27 years old and in her first semester at Yale Law School, when she experienced these terrifying sensations, she was diagnosed with "chronic paranoid schizophrenia with acute exacerbation".
I do not think I have the courage to read Elyn Saks' evidently remarkable autobiography, "The Center Cannot Hold: My Journey Through Madness". I did, however, read the review in the New York Review of Books (Vol 15 No 6. 17 April 2008, Infiltrating the Mind of the Enemy. Jay Neugeboren) with mounting fascination. The reviewer writes: "There is a long tradition, published and unpublished, of first person accounts of madness .... but [this] is the most remarkable of all. I know of no other account that, by its recall of each moment of short- and long-term crises, allows us to begin to experience what being in this condition must be like and feel like to the person suffering it."
If this seems rather technical and some distance from conductive education and evidence-based practice, bear with me for moment longer and I will shortly come to the point that gripped me as I read the review.
Now 52 and having "suffered several major psychotic episodes" since, Elyn was never again hospitalised for psychiatric reasons. She has successfully managed her condition - she has married, become a Professor and a published author - by medication and psychoanalysis. I cannot do justice, in a few words, to the account that the reviewer summarises. Then he writes:
The prevailing view, beginning with Freud, is that when it comes to schizophrenia, psychoanalysis and most forms of talk therapy invariably cause relapse and regression.
Then came the sentence that grabbed my attention:
"More recently, especially given the ascendancy of evidence-based medicine and its emphasis on 'recovery' - on measurable reduction of symptoms that provides evidence of improvement - analysis and talk therapy have plummeted from favor". [My italics]
There is a lengthy footnote to this, the first half of which reads:
"Evidence-based medicine attempts to assess the quality of evidence relevant to risks and benefits of treatment (including lack of treatment). The term first appeared in medical literature in 1992: the most common definition is David Sackett's: Evidence-based medicine is the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients" ....
One might conclude that the reason "analysis and talk therapy plummeted from favor" was because it lacked an evidence base. It "did not work" and was apparently, to use David Colquhoun's word, regarded as "baloney". (Please note I am here only borrowing David Colquhoun's distinction about 'what works and what does not' and not attributing to him, in any sense, that he regards analysis and talk therapy as 'baloney'.] Our conclusion might be correct. The reviewer asserts that in the American Psychiatric Association's Practice Guideline for the Treatment of Patients with Schizophrenia (2004) the only 'talk therapy' recommended is the "evidence-based practice" cognitive behavioural therapy (CBT), a short-term therapy.
In the second half of that same footnote, the reviewer continues:
One problem, when evidence based medicine is applied to chronic mental illness, is that it is easier to measure - to quantify - symptoms and symptom reduction, and, thus, the efficacy of medications, than it is to measure intangibles that, in often grim, unenviable lives, pertain to quality of life, however diminished the quality of those lives might be." [My italics again]
Quality of life. The reviewer writes:
"While medications may reduce symptoms, what, for a person who has lived for any extended period with madness, of the fear and the shame, of the isolation and feelings of worthlessness that invariably accompany madness?"
Is there an evidence-based way to measure the benefits, the reviewer asks, to someone suffering the pain of psychosis of 'letting go' in talk therapy; or the difference that "tolerance, patience and understanding" can make in a person's life and to the quality of that life?
Quality of life. A generation later and a continent away from Elyn Saks, a young woman, wife and a mother of two small children, has had a course of chemotherapy that has apparently been successful. The cancer, however, returns and is again treated with chemotherapy but this time is less successful. She is offered the treatment for a third time, told that it will most probably only extend her life by some months. She thinks of her husband and her children and she thinks of the quality of her life while she undergoes treatment - and decides, quite rationally, to reject the treatment.
The alternative to evidence-based practice, as I noted in Part 2, following David Colquhoun, is not "magic" or "baloney", but more evidence-based practice: discovering what works and what does not. However, as the reviewer notes, and as the young wife and mother weighed in the balance for herself, there may be factors beyond or outside or maybe even in conflict with the proper application of evidence-based practice.
For Elyn Saks, evidence-based medication may well have alleviated her terrifying symptoms - she came to terms with the need for life-long medication alongside talk therapy - but what can alleviate the fear that the symptoms will re-occur? The answer is surprising: rather than medication or talk therapy "friendship can be as powerful as either"; she is, she says of her friends, "both comforted and moved that they'd come at all".
My apologies to those who may have seen an early draft of Part 3 which I posted by error and then cancelled.
