Persistence and resolution of suicidal ideation during treatment of depression in patients with significant suicidality at the beginning of treatment: The CRESCEND study

초록

Background: The appropriate length of time for patients who visit clinics with significant suicidal ideation to be closely monitored is a critical issue for clinicians. We evaluated the course of suicidal ideation and associated factors for persistent suicidality in patients who entered treatment for depression with significant suicidal ideation. Methods: A total of 565 patients who had both moderate to severe depression (Hamilton Depression Rating Scale (HAMD) score r-E-, 14) and significant suicidal ideation (Beck Scale for Suicide Ideation (SSI-B) score >= 6) were recruited from 18 hospitals in South Korea. Participants were assessed using the SSI-B, HAMD, Hamilton Anxiety Rating Scale, and Clinical Global Impression Scale-severity during a 12-week naturalistic treatment with antidepressant intervention. Participants were classified into resolved suicidality or persistent suiciclaliiy groups according to whether their suicidal ideation improved to SSI-B scores <6 and were sustained for 12 weeks. Results: During the 12-week treatment, 206 (36.4%) patients were classified in the resolved su c clality group. Persistent suicidality was associated with intervention with SSRls, higher SSI-B baseline score, and no HAMD or HALV1A remission. The proportions of participants who had persistent suicidal ideation even with HAMD remission or response were 0.25 and 0.34, respectively. Limitations: This study was observational, and ihe treatment modality was naturalistic. Conclusions: A considerable number of patients had persistent suicidal ideation despite 12 weeks of antidepressant treatment. Close monitoring for suicidal ideation may be needed beyond the initial weeks of treatment and even after a response to antidepressants is observed. (C) 2014 Elsevier E3.\/. All rights reserved
