目的确定使用明信片(EDGE项目的明信片)进行干预是否能减少医院治疗故意自杀的重复次数。设计随机对照试验。在纽卡斯尔建立综合医院治疗故意自杀的区域转诊服务，研究对象为772名年龄在16岁以上的故意自杀患者。采用8张明信片进行非强制性干预，为期7个月，同时进行标准治疗，并与单纯标准治疗进行比较。主要结果衡量在12个月内有一次或多次故意自杀的患者所占比例和人均故意中毒的次数。结果干预组与对照组故意自杀的复发者比例无显著差异(57/378，15.1%，95%可信区间11.5%~18.7%v68/394，17.3%，P<0.05)。13.5%至21.0%：组间差异-2%，-7%至3%)。在未调整的分析中，重复次数显著减少(发生率风险比0.55，0.35至0.87)。结论明信片干预减少了故意自杀的重复次数，但并未显著降低个体重复中毒的比例。
Objective To determine whether an intervention using postcards (postcards from the EDge project) reduces repetitions of hospital treated deliberate self poisoning.Design Randomised controlled trial.Setting Regional referral service for general hospital treated deliberate self poisoning in Newcastle, Australia.Participants 772 patients aged over 16 years with deliberate self poisoning.Intervention Non-obligatory intervention using eight postcards over 7 2 months along with standard treatment compared with standard treatment alone.Main outcome measures Proportion of patients with one or more repeat episodes of deliberate self poisoning and the number of repeat episodes for deliberate self poisoning per person in 12 months.Results The proportion of repeaters with deliberate self poisoning in the intervention group did not differ significantly from that in the control group (57/378, 15.1%, 95% confidence interval 11.5'% to 18.7% v 68/394,17.3%,13.5% to 21.0%: difference between groups - 2%, - 7% to 3%). In unadjusted analysis the number of repetitions were significantly reduced (incidence risk ratio 0.55, 0.35 to 0.87).Conclusion A postcard intervention reduced repetitions of deliberate self poisoning, although it did not significantly reduce the proportion of individual repeaters.
