High rates of suicide have been reported in psychotic disorders, particularly in the early phases. Studies examining suicide risk during the first episode of psychosis (FEP) are lacking, especially in the Asian context. The present study aims to investigate the prevalence of completed suicides and associated risk factors in a multi-ethnic Asian society.
Data from 1397 patients accepted into a local Early Psychosis Intervention Programme (EPIP) was collected. This included sociodemographic and clinical data. Cox proportional-hazards regression models were performed in order to explore factors associated with time to completed suicide.
The sample comprised of 1397 FEP patients, with 687 females and 710 males. The mean age was 28.2 years. The prevalence of suicide in this sample was 1.9%. Of the 26 FEP patients who committed suicide, data on time to suicide was available for 23 of them. 56.5% committed suicide during the first year of follow-up. A higher risk of suicide was associated with an older age (Hazard Ratio (HR)=1.31, 95% CI, 1.05-1.63), longer DUP (HR=1.05, 95% CI, 1.02-1.11), higher PANSS positive (HR=1.91, 95% CI, 1.37-2.67), higher GAF symptomatology (HR=1.16, 95% CI, 1.04-1.30) and GAF disability scores (HR=1.12, 95% CI, 1.02-1.22).
Older patients with longer DUPs, higher PANSS positive and negative scores and better functioning appear to be at higher risk of suicide in this sample. Early intervention services should focus on a thorough risk assessment in order to reduce the risk of suicide during FEP.
本研究旨在调查一个多民族亚洲社会中精神分裂症患者首次发病期间(FEP)的自杀发生率和相关危险因素。
收集了当地早期精神病干预计划(EPIP)中 1397 名患者的数据,包括人口统计学和临床数据。采用 Cox 比例风险回归模型探讨与自杀时间相关的因素。
样本包括 1397 例 FEP 患者,其中女性 687 例,男性 710 例,平均年龄 28.2 岁。该样本的自杀率为 1.9%。在 26 例自杀的 FEP 患者中,有 23 例的自杀时间数据可用。56.5%的患者在随访的第一年自杀。自杀风险较高与年龄较大(危险比(HR)=1.31,95%置信区间(CI),1.05-1.63)、较长的 DUP(HR=1.05,95%CI,1.02-1.11)、较高的 PANSS 阳性(HR=1.91,95%CI,1.37-2.67)、较高的 GAF 症状(HR=1.16,95%CI,1.04-1.30)和 GAF 残疾评分(HR=1.12,95%CI,1.02-1.22)相关。
在本样本中,年龄较大、DUP 较长、PANSS 阳性和阴性评分较高、功能较好的患者自杀风险较高。早期干预服务应重点进行全面风险评估,以降低 FEP 期间的自杀风险。
