The current report describes individuals with bipolar disorder who attempted or completed suicide while participating in the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) study.
Baseline and course features of individuals with suicide events are described.
Among the 4360 people with bipolar disorder enrolled, 182 individuals made 270 prospectively observed suicidal acts, including 8 completed suicides. This represents a suicide rate of .014 per 100 person years in STEP-BD, which included frequent clinical visits, evidence based care, and standardized assessment at each patient contact. Approximately 1/3 of those who attempted suicide had more than one attempt during study participation. Those who completed suicide tended to do so early in study participation, and half of them did so on their first attempt.
While this study is limited to description of individuals and precipitants of completed suicides and attempts in STEP-BD, further analyses are planned to explore risk factors and potential interventions for prevention of suicidal acts in persons with bipolar disorder.
Persons with bipolar disorder are at high risk for suicide. Overall rates of suicide events in STEP-BD were lower than expected, suggesting that the combination of frequent clinical visits (i.e., access to care), standardized assessment, and evidence-based treatment were helpful in this population.
本报告描述了在参加心境障碍系统化治疗增强项目(STEP-BD)研究的过程中试图或完成自杀的双相情感障碍患者。
描述了有自杀事件个体的基线和病程特征。
在纳入的 4360 例双相情感障碍患者中,182 例个体有 270 次前瞻性观察到的自杀行为,包括 8 例自杀死亡。这代表在 STEP-BD 中每 100 人年发生 0.014 例自杀,其中包括频繁的临床就诊、基于证据的治疗和在每次患者接触时进行标准化评估。大约 1/3 的自杀未遂者在研究期间有不止一次尝试。完成自杀的个体往往在研究早期就这么做了,其中一半人第一次尝试就自杀了。
虽然这项研究仅限于描述 STEP-BD 中完成自杀和未遂自杀的个体及其促发因素,但计划进一步分析以探讨预防双相情感障碍患者自杀行为的风险因素和潜在干预措施。
双相情感障碍患者自杀风险很高。在 STEP-BD 中自杀事件的总发生率低于预期,这表明频繁的临床就诊(即获得治疗的机会)、标准化评估和基于证据的治疗相结合对该人群是有帮助的。
