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.

伊朗德黑兰的善后和自杀预防再次发生。

背景：先前的自杀未遂是随后自杀的最大危险因素之一。自杀未遂后进行有效护理可能会降低自杀重试的风险。目的：我们旨在调查简短的教育干预和联系计划对自杀重试的影响。方法：本研究是作为一项随机临床试验（RCT）进行的，招募了305名曾尝试自杀的人（简短干预和接触= 153人，BIC；照常治疗= 152人，TAU），这些人被转诊到德黑兰的Baharlu医院。SUPRE-MISS调查表和出院随访调查表用于数据收集。使用Cox比例风险模型和对数秩检验来评估变量与事件的关联（重新尝试）。Kaplan-Meier曲线用于描述重新尝试事件的时间。结果：在BIC组中，有11％的人曾尝试过一次自杀，而在TAU组中，有25％的人曾尝试过一次自杀（12.4％），两次（9.3％）和三次（3.8％）。Kaplan-Meier分析的结果表明，分别在随访的第四个月和第二个月，BIC组（0.76）和TAU组（0.25）的平均重新尝试时间（log rank，χ2= 12.48，p <.001） 。TAU组的危险比为2.57（95％CI [1.4，5.9]）。局限性：由于耻辱而导致的后续工作损失是后续服务的严重问题之一。结论：实施简短的自杀再举教育干预和联系计划是切实可行的，有效的降低了自杀再举率。然而，
