背景严重精神疾病（SMI）的定义在实践中缺乏一致性，也没有可操作的定义，目的是检验两个可操作的定义，基于国家精神卫生研究所（1987）的定义：第一个使用三个标准（诊断为精神病;服务接触时间大于或等于2年; GAF评分小于或等于50），方法计算两个欧洲集水区SMI的年患病率，分别为每种标准和组合标准，结果第一种定义的患病率为2.55和1.34/1000在伦敦和维罗纳，分别;第二个允许额外的0.98/1000非精神病性障碍被列入Verona.Conclusions的三维定义选择一个小组的SMI患者有精神障碍。二维方法允许估计包括所有形式的精神障碍的SMI患病率。
Background There is little consistency in how severe mental illness (SMI) is defined in practice, and no operational definitions.Aims To test two operationalised definitions, based on the National Institute of Mental Health (1987) definition: the first uses three criteria (diagnosis of psychosis; duration of service contact greater than or equal to 2 years; GAF score less than or equal to 50), the second only the last two.Method Annual prevalence rates of SMI in two European catchment areas for each criterion and the criteria combined were calculated.Results The first definition produced rates of 2.55 and 1.34/1000 in London and Verona, respectively; the second permitted an additional 0.98/1000 nonpsychotic disorders to be included in Verona.Conclusions The three-dimensional definition selects a small group of patients with SMI who have psychotic disorders. The two - dimension al approach al lows estimates of SMI prevalence rates which include all forms of mental disorder.Declaration of interest Funding provided by the University of Verona and the Bethlem and Maudsley NHS Trust.
