abstract

  • OBJECTIVE: It is unknown what next-step strategies are being used in clinical practice for patients with obsessive-compulsive disorder (OCD) who do not respond to first-line treatment. As part of a cross-sectional study of OCD, treatment and symptom information was collected. METHOD: Consecutive OCD out-patients in nine international centers were evaluated by self-report measures and clinical/structured interviews. OCD symptom severity was evaluated by the Yale Brown Obsessive Compulsive Scale (YBOCS) and Clinical Global Impression-Severity Scale (CGI-S). Clinical response to current treatment was evaluated by the CGI-Improvement Scale (CGI-I ≤ 2). RESULTS: In total, 361 participants reported taking medication; 77.6% were taking a selective serotonin reuptake inhibitor; 50% reported use of at least one augmentation strategy. Antipsychotics were most often prescribed as augmenters (30.3%), followed by benzodiazepines (24.9%) and antidepressants (21.9%). No differences in OCD symptom severity were found between patients taking different classes of augmentation agents. CONCLUSIONS: Results from this international cross-sectional study indicate that current OCD treatment is in line with evidence-based treatment guidelines. Although augmentation strategies are widely used, no significant differences in OCD symptom severity were found between monotherapy and augmentation or between different therapeutic agents.
