A research team from the University of Bologna in Italy have published a new meta-anlaysis that explores the sequential integration of psychotherapy and pharmacotherapy in reducing the risk of relapse and recurrence in major depressive disorder.
They searched a range of databases for randomised controlled trials that tested the efficacy of the administration of psychotherapy after successful response to acute-phase pharmacotherapy in the treatment of adults with depression. They found 8 good quality trials, which when combined, involved 442 patients in a sequential treatment arm and 433 in a control treatment arm.
Their analysis turned up some promising results:
- The pooled risk ratio (RR) for relapse/recurrence was 0.797 [95% confidence interval (CI) 0.659-0.964] according to the random-effects model, suggesting a relative advantage in preventing relapse/recurrence for the sequential administration of treatments compared with control conditions
- Psychotherapy during continuation of antidepressant drugs compared favourably to antidepressants or treatment as usual (RR 0.842, 95% CI 0.674-1.051)
- Patients randomised to psychotherapy while antidepressants were discontinued were significantly less likely to experience relapse/recurrence compared to controls (RR 0.650, 95% CI 0.463-0.912).
We found evidence that the sequential integration of psychotherapy and pharmacotherapy is a viable strategy for preventing relapse and recurrence in major depressive disorder. In addition, our findings suggest that discontinuation of antidepressant drugs may be feasible when psychotherapy is provided.
