One hundred patients who were injured by London underground trains during 1981-6 were studied; 43 of them died. Deliberate self harm was probable in roughly three quarters. Alcohol intoxication was thought to play an important part in a further tenth of cases. Thirteen were psychiatric inpatients at the time of the incident, and a further two had recently been discharged. Early warning of a potential suicide attempt was given during the 24 hours preceding the incident in 15 of the cases. Some of the deaths in the psychiatric patients may have been preventable.
对1981年至1986年间在伦敦地铁列车事故中受伤的100名患者进行了研究；其中43人死亡。大约四分之三的死亡可能是蓄意自残。另有十分之一的病例中，酒精中毒被认为起了重要作用。13人在事故发生时是精神病住院患者，另外2人最近刚出院。15例事故发生前24小时内有潜在自杀企图的早期预警。精神病患者中的一些死亡可能是可以预防的。
