Background: A previous suicide attempt is one of the strongest risk factors for subsequent suicide. Effective care following a suicide attempt may reduce the risk of suicide reattempts. Aims: We aimed to investigate the effect of a brief educational intervention and contact program on suicide reattempts. Method: This study was performed as a randomized clinical trial (RCT) recruiting 305 individuals who had attempted suicide (brief intervention and contact = 153 individuals, BIC; treatment as usual = 152 individuals, TAU) who were referred to Baharlu Hospital in Tehran. The SUPRE-MISS questionnaire and a discharge follow-up questionnaire were used for data collection. Cox proportional hazard models and log-rank tests were used to assess the association of the variable with the event (reattempt). Kaplan-Meier curves were used to depict the time to the event of reattempt. Results: In the BIC group, 11% of the individuals had attempted suicide once, and 25% of the TAU group had attempted suicide once (12.4%), twice (9.3%), and three times (3.8%), respectively. The results of Kaplan-Meier analysis indicated the mean time of reattempt in the BIC (0.76) and TAU groups (0.25) as the fourth and second months of follow-up, respectively (log rank, χ2 = 12.48, p < .001). The hazard ratio for the TAU group was 2.57 (95% CI [1.4, 5.9]). Limitations: Loss to follow-up due to stigma is one of the serious problems of follow-up services. Conclusion: Implementing a brief educational intervention and contact program on suicide reattempts is feasible and effective in reducing the rate of reattempt; however, it should be accommodated within the mental health services of the county.

伊朗德黑兰的善后护理和自杀重试预防。

背景：先前的自杀未遂是随后自杀的最强风险因素之一。自杀未遂后的有效护理可以降低再次尝试自杀的风险。目的：我们旨在调查简短的教育干预和联系计划对再次尝试自杀的影响。方法：本研究作为一项随机临床试验 (RCT) 进行，招募了 305 名曾试图自杀的人（短暂干预和接触 = 153 人，BIC；照常治疗 = 152 人，TAU），他们被转诊到德黑兰的巴哈鲁医院。SUPRE-MISS 问卷和出院随访问卷用于数据收集。Cox 比例风险模型和对数秩检验用于评估变量与事件（重试）的关联。Kaplan-Meier 曲线用于描述重试事件的时间。结果：在 BIC 组中，11% 的个体尝试过自杀一次，25% 的 TAU 组分别尝试过自杀一次（12.4%）、两次（9.3%）和 3 次（3.8%）。Kaplan-Meier 分析结果表明，BIC（0.76）和 TAU 组（0.25）的平均重试时间分别为随访的第 4 个月和第 2 个月（对数秩，χ2 = 12.48，p < .001） . TAU 组的风险比为 2.57（95% CI [1.4, 5.9]）。局限性：因污名而失访是随访服务的严重问题之一。结论：对重试自杀实施简短的教育干预和联系计划在降低重试率方面是可行且有效的；然而，
