T217. FACTORS RELATED TO SUICIDAL BEHAVIOR IN KOREAN PATIENTS WITH BIPOLAR DISORDER: THE EFFECT OF MIXED FEATURES ON SUICIDALITY

BACKGROUND: The aim of the present study was to investigate various risk factors of suicidal behaviors, including mixed feature specifier, in Korean patients with bipolar disorder. METHODS: We retrospectively reviewed medical charts from 2005 to 2014. A total of 334 patients diagnosed with bipolar disorder using DSM-IV TR were enrolled. The subjects were categorized into two groups according to history of suicidal behaviors and compared regarding demographic and clinical characteristics including mixed feature specifier. We re-evaluated the index episode using the DSM-5 criteria and classified into index episode with and without mixed feature. Logistic regression was performed to evaluate significant risk factors associated with suicidal behavior. RESULTS: Suicidal behavior had independent relationship with mixed feature at index episode using DSM-5 criteria and number of previous depressive episodes in Korean bipolar patients. The mixed feature specifier was the strongest risk factor in the present study. DISCUSSION: Suicidal behavior had independent relationship with mixed feature at index episode using DSM-5 criteria and number of previous depressive episodes in Korean bipolar patients. The mixed feature specifier was the strongest risk factor in the present study.
