: There is little information about characteristics and long-term outcomes of individuals who self-harm during a suicide cluster. : To compare characteristics of individuals who self-harmed during a suicide cluster in South Wales (∼10 deaths between December 2007 and March 2008) with others who self-harmed prior to the cluster and to evaluate 10-year self-harm and mortality outcomes. : Using records from the hospital serving the catchment area of the suicide cluster, enhanced by national routinely collected linked data, we created the following two groups: individuals who self-harmed (a) during the suicide cluster and (b) 1 year before. We compared individuals' characteristics and performed logistic regression to compute odds ratios of 10-year self-harm and mortality outcomes. : Individuals who self-harmed during the cluster were less likely to be hospitalized or have a mental health history than those who self-harmed prior to the cluster. No significant group differences were found for 10-year self-harm outcomes, but all-cause mortality was higher for males. : Sample size was small, and data were lacking on psychological and social proximity to individuals who died during the suicide cluster. : Our findings highlight the importance of long-term healthcare follow-up of those who self-harm during a suicide cluster, particularly males.
关于在自杀集群期间自残的个体的特征和长期结局的信息很少。为了比较在南威尔士自杀集群期间自残的个体（2007 年 12 月至 2008 年 3 月期间约有 10 人死亡）的特征与集群前自残的个体，并评估 10 年自残和死亡率结局。使用为自杀集群服务的医院记录，并通过国家常规收集的链接数据进行增强，我们创建了以下两个组：（a）在自杀集群期间自残的个体和（b）在集群前一年自残的个体。我们比较了个体的特征，并进行逻辑回归计算 10 年自残和死亡率结局的优势比。在集群期间自残的个体与集群前自残的个体相比，住院或有精神病史的可能性较小。对于 10 年自残结局，没有发现显著的组间差异，但男性的全因死亡率较高。样本量较小，并且缺乏关于与自杀集群期间死亡的个体在心理和社会上的接近程度的数据。我们的研究结果强调了对自杀集群期间自残的个体进行长期医疗保健随访的重要性，尤其是男性。
