Self-poisoning is a common reason for admission to hospital; and, although most patients admitted do not have a psychiatric disorder, as a group they are at greatly increased risk of completed suicide. Admissions to a hospital in Central London over a four-year period were examined with special attention to patients admitted more than once. From 1991 to 1994 admissions for self-poisoning rose by 108%, with larger increases in the younger age groups of both sexes. 9% of patients were admitted more than once, the mean interval to repetition being three months. A third of the repeaters were readmitted within one month. The increase in admissions for self-poisoning, which has been noted elsewhere in the UK, is unlikely to be due wholly to changes in clinical practice. In view of the relation between parasuicide and suicide, further research and analysis is urgently needed.
自我中毒是住院的常见原因；而且，尽管大多数入院患者没有精神疾病，但作为一个群体，他们完成自杀的风险大大增加。对伦敦市中心一家医院四年期间的入院情况进行了检查，特别关注多次入院的患者。1991年至1994年，自我中毒入院人数增加了108%，在两个性别的较年轻年龄组中增加幅度更大。9%的患者多次入院，再次入院的平均间隔时间为三个月。三分之一的再次入院患者在一个月内再次入院。自我中毒入院人数的增加在英国其他地方也有记录，不太可能完全归因于临床实践的变化。鉴于准自杀与自杀之间的关系，迫切需要进一步的研究和分析。
