Trust medical science at your peril (2): What is the evidence, especially in psychiatry?
Posted by Henry Bauer on 2016/07/15
All too often, the evidence turns out to be nothing more than statistical association: “Trust medical science at your peril: Correlations never prove causation”.
A particular example of confusing association with causation is the reliance on biomarkers:
“The Institute of Medicine Report, Evaluation of Biomarkers and Surrogate Endpoints in Chronic Disease (IOM 2010), finds that none of the commonly used biomarkers is a valid measure of the illness it supposedly tracks. As to subsequent treatment, Järvinen et al. have pointed out that ‘There are no valid data on the effectiveness . . . [of] statins, antihypertensives, and bisphosphanates’ (the last, e.g. Fosamax, are prescribed against osteoporosis) — British Medical Journal, 342 (2011) doi: 10.1136/bmj.d2175.
That last quote is surely an astonishing assertion, given that innumerable individuals are being fed statins and blood-pressure drugs and bisphosphanates not because they feel ill in any way but purely on the basis of levels of biomarkers (bone density in the case of bisphosphanates)” (Everyone is sick?)
Supporting evidence is sadly lacking for a wide range of accepted, standard medical practices. For at least a couple of decades, insiders and well-informed observers have described and documented the failings of modern medicine: “What’s wrong with present -day medicine”.
Bad as things are with the treatment of physical illnesses, they are much worse where psychiatry is involved. This blog post was stimulated by the informative article, “In Search of an Evidence-based Role for Psychiatry” by John Read, Olga Runciman, & Jacqui Dillon.
I had learned of it through the Newsletter of Mad in America, an excellent website dedicated to disseminating reliable information about psychiatric matters. One can sign up for the Newsletter at http://www.madinamerica.com/mia-newsletter-signup/.
