EBM in practice: psychiatry.

Psychiatry was one of the first medical specialties to use the tools of evidence-based medicine (EBM)--randomised controlled trials (RCTs), systematic reviews with meta-analyses--and as many treatment decisions in psychiatry are evidence-based as in general medicine. Psychiatrists have some reservations about the EBM approach because of perceived limitations in methodology of RCTs and systematic reviews; gaps in the evidence base; problems interpreting the available evidence; and neglect of individual patient uniqueness in quantitative research based on groups or populations. Research supports the value of psychotherapy and there are now a number of empirically validated efficacious psychotherapies for a range of disorders.
