Impact of the number of changes of therapeutic strategy on improvement in depressed patients. dria study

Abstract

Introduction

The STAR*D is a pragmatic clinical trial that showed lower remission rate and higher relapse rate when more strategies were used.[1]

Objectives and aims

Assess clinical improvement in symptoms related to depression, anxiety and sleep, based on the number of strategies used.

Methods

Descriptive, non-interventional, prospective study including outpatients diagnosed with Major Depressive Disorder (MDD) with sub-optimal response to standard antidepressants. In those patients a change on the therapeutic strategy (switch of antidepressant, combination of antidepressants, augmentation or a combination of previous strategies) had to be considered necessary. Follow-up period was 22–26 weeks.

Results

364 patients were included by 58 psychiatrists, 336 were analyzed (92.3%) and 315 (86.5%) completed the follow-up.
