Ontario government statistics have indicated that during the 1960s the proportion of readmissions to psychiatric hospitals doubled to form two thirds of all admissions. Since this pertained to events rather than to individuals, a cohort of patients first admitted in 1969 was followed for 4 years to trace the pattern of readmission and the characteristics of patients at risk of readmission. Routinely returned data were linked and a sample from the greater metropolitan Toronto area was randomly selected. Of the cohort, 31% were readmitted, 8% three or more times. Age and diagnosis distinguished those readmitted. Most with multiple readmissions were under 25 years of age. Although diagnoses were equally distributed on first admission among psychotic, neurotic and other nonpsychotic disorders, with no significant change on readmission or multiple readmission, there was a predictably greater proportion of functional psychoses among the high-risk group and also an equal representation of personality, addictive and the remaining nonpsychotic conditions. The vulnerable few are identifiable early in their intermittent hospital career. It can be concluded that statistics suggesting that two thirds of admissions are readmissions are misleading.
安大略省政府的统计数据表明，在20世纪60年代，精神病院再次入院的比例翻了一番，占所有入院人数的三分之二。由于这涉及事件而非个人，因此对1969年首次入院的一组患者进行了4年的跟踪，以追踪再次入院的模式以及有再次入院风险的患者特征。将常规返回的数据进行关联，并从大多伦多地区随机抽取样本。在该队列中，31%的患者再次入院，8%的患者再次入院三次或更多次。年龄和诊断结果能够区分出再次入院的患者。大多数多次再次入院的患者年龄在25岁以下。尽管首次入院时，精神病、神经症和其他非精神病性障碍的诊断分布均匀，再次入院或多次再次入院时也没有显著变化，但高危组中功能性精神病的比例预计会更高，人格障碍、成瘾性疾病和其他非精神病性疾病的比例也相当。少数易受影响的患者在其间歇性住院治疗过程中可以早期识别。可以得出结论，表明三分之二的入院患者是再次入院患者的统计数据具有误导性。
