A study of the diagnostic composition of the inpatient population of Ontario and Canadian psychiatric facilities has shown an important change in hospital-treated illness over the period 1941-71. Patients with nonpsychotic disorders accounted for 54% of all admissions to Ontario public mental hospitals in 1971, compared with only 8% in 1941. The trend was similar for both first admissions and proportion of readmissions, and was similar for psychiatric units of general hospitals. In contrast, the overall rate of first admission for psychotic disorders to inpatient facilities remained remarkably constant over time, as did the proportion of readmissions among all admissions. The findings dispel the notion that the increasing proportion of readmissions is due largely to a rapid turnover of former long-stay psychotic patients (the "revolving-door phenomenon"). The findings could not be attributed to a changing prevalence of types of psychiatric illness, increased availability of psychiatric inpatient facilities or comprehensive medical insurance.
一项针对安大略省和加拿大精神病院住院患者诊断构成的研究表明，在1941年至1971年期间，医院治疗的疾病发生了重大变化。1971年，患有非精神病性障碍的患者占安大略省公立精神病院所有入院患者的54%，而1941年这一比例仅为8%。首次入院和再入院比例的趋势相似，综合医院的精神科病房情况也类似。相比之下，精神病性障碍患者首次入住住院机构的总体比例随时间推移保持显著稳定，所有入院患者中的再入院比例也是如此。这些发现消除了再入院比例增加主要是由于以前长期住院的精神病患者快速周转（“旋转门现象”）这一观念。这些发现不能归因于精神疾病类型患病率的变化、精神科住院设施可及性的提高或综合医疗保险。
