Psychiatry Loses Another One

    Do not think about, write about or deal with  human behavior without determining the effects of incentives. It’s not their money, of course they’ll waste it.

    Wherein we see another shibboleth of psychiatry undermined. Psychiatry held for decades that, while psychotherapy was fine for minor and moderate depression, only pharmaceuticals could deal with severe depression. The following shows this may not be true. This is not disconfirmation because drugs as the only useful treatment for severe depression was never confirmed. Since not much in psychiatry is better than placebo, one wonders what is next.

Antidepressants Not Superior to Psychotherapy for Severe Depression

On Wednesday, JAMA Psychiatry released a meta-analysis comparing the results of cognitive-behavioral therapy and antidepressant medication in severely depressed populations.  Currently, many practice guidelines suggest that antidepressants be used over psychotherapy for major depressive disorder. The analysis, however, found that “patients with more severe depression were no more likely to require medications to improve than patients with less severe depression.”

In their guidelines for the treatment of depression, both the American Psychiatric Association (APA) and the British Association for Psychopharmacology suggest that while “psychotherapy is sufficient for treating mild depression, antidepressant medications (ADMs) should be used to treat severe depression in the context of major depressive disorder.”  These guidelines are based largely on the results of a randomized control trial conducted by the NIMH.  However, this latest meta-analysis reveals that the difference in treatment outcomes observed in the NIMH trials “were not observed in several other randomized clinical trials (RCTs) of acute-phase treatment.”

While previous meta-analyses have attempted to compare ADMs and CBT for depression, the latest study is unique in that the researchers were able to obtain patient-level data, giving the study “more power to examine accurately moderators of treatment outcomes.”  The researchers reviewed 16 studies that provided individual patient-level data and eight that did not.  All told, the sample included data on 1,700 participants.

The results of the analysis show no significant differences between antidepressants and CBT in response to treatment or remission in patients with severe depression.  “In total, 63% of patients in the ADM condition and 58% of patients in the CBT condition responded to treatment, and 51% of patients in the ADM condition and 47% of patients in the CBT condition met criteria for remission.”

The researchers conclude that “the data are insufficient to recommend ADM over CBT in outpatients based on baseline severity alone.” They also suggest that CBT may be used an effective first-line treatment for severely depressed patients.
