This slide compares the guideline recommendations for patients with inadequate response to antidepressant monotherapy from four internationally-recognised bodies:

1.American Psychiatric Association (APA)1

2.National Institute for Health and Care Excellence (NICE)2

3.British Association for Psychopharmacology (BAP)3

4.World Federation of Societies of Biological Psychiatry (WFSBP)4

5.Canadian Network for Mood and Anxiety Treatments (CANMAT)5,6

Each body rates their guideline recommendations according to the level of clinical evidence available.

There are four categories, ranked from the strongest to the least evidence:

  • Substantial clinical confidence (strongest supporting evidence)
  • Moderate clinical confidence
  • Low clinical confidence
  • No clinical confidence (no or little supporting evidence)
