BACKGROUND Research is required to identify those psychiatric interventions with a protective effect against suicide. The overarching aim of the current study was to examine whether completed suicide in psychiatric patients in a Swedish population was associated with the quantity and nature of previous medical and psychosocial treatment interventions. METHODS This retrospective case-control study (n = 308) compared a group of deceased psychiatric patients with matched controls. For every case of suicide, a control was found within psychiatry that matched according to sex, age, and primary psychiatric diagnosis. A stepwise forward logistic regression model with suicide as the dependent outcome variable was used. RESULTS Receiving pharmacotherapy combined with psychotherapy [OR: 0.44 (95% CI: 0.226-0.876), p = 0.019] and a higher number of outpatient visits in psychiatry [OR: 0.99 (95% CI: 0.982-0.999), p = 0.028] were negatively associated with suicide. These associations were still significant after controlling for previous serious suicide attempts and somatic comorbidity. CONCLUSIONS Frequent visits and pharmacotherapy combined with psychotherapy seem to be important for preventing suicide in psychiatric patients. The reasons for not receiving such therapy are important issues for further study.

精神干预的数量和内容是否与自杀有关？瑞典样本的病例对照研究。

背景技术需要进行研究以鉴定对自杀具有保护作用的精神病干预措施。本研究的总体目标是检查瑞典人群中精神病患者完全自杀与以前的医学和社会心理干预措施的数量和性质是否相关。方法这项回顾性病例对照研究（n = 308）比较了一组已死亡的精神病患者和相匹配的对照。对于每例自杀病例，根据性别，年龄和主要精神病学诊断，在精神病学中发现了一个对照。使用自杀作为因变量的逐步前向逻辑回归模型。结果接受药物治疗与心理治疗相结合[OR：0.44（95％CI：0.226-0.876），p = 0。019]和更高的精神科门诊就诊率[OR：0.99（95％CI：0.982-0.999），p = 0.028]与自杀呈负相关。在控制以前的严重自杀未遂和躯体合并症之后，这些关联仍然很重要。结论经常拜访和药物治疗结合心理治疗似乎对预防精神病患者自杀很重要。不接受这种治疗的原因是有待进一步研究的重要问题。结论经常拜访和药物治疗结合心理治疗似乎对预防精神病患者自杀很重要。不接受这种治疗的原因是有待进一步研究的重要问题。结论经常拜访和药物治疗结合心理治疗似乎对预防精神病患者自杀很重要。不接受这种治疗的原因是有待进一步研究的重要问题。
