BACKGROUND
It is suggested that the incidence of schizophrenia is decreasing. However, changes in the number of psychiatric beds available and diagnostic practice have not always been taken into account. We studied the annual first-admission rate (per 100,000) for schizophrenia (FARsch) during a rapid deinstitutionalisation period in Finland.
METHOD
From the National Finnish Hospital discharge register, we identified all 30,041, 15- to 64-year-old patients admitted for the first time with schizophrenia to hospitals in Finland between 1980 and 2003.
RESULTS
FARsch decreased from 56.39 in 1980 to 29.51 in 1991 and slightly increased thereafter. Changes in FARsch corresponded with changes in all admissions. FARsch was higher when using ICD-8, but lower when DSM-IIIR and ICD-10 were used.
CONCLUSION
Changes in the number of psychiatric beds available, admission policy and diagnostic practice may explain the majority of variations in FARsch. Possibly, increased use of illegal drugs and improved treatment of depression are reflected in the increase in FARsch.
背景
有研究表明精神分裂症的发病率正在下降。然而，精神科床位数量的变化和诊断实践并未始终得到考虑。我们研究了芬兰快速去机构化期间精神分裂症的年首次入院率（每 10 万人）。
方法
我们从国家芬兰住院记录中确定了所有 1980 年至 2003 年间芬兰医院收治的年龄在 15 至 64 岁之间首次因精神分裂症入院的 30041 名患者。
结果
FARsch 从 1980 年的 56.39 降至 1991 年的 29.51，此后略有上升。FARsch 的变化与所有入院人数的变化相对应。使用 ICD-8 时 FARsch 更高，但使用 DSM-IIIR 和 ICD-10 时 FARsch 更低。
结论
精神科床位数量、入院政策和诊断实践的变化可能解释了 FARsch 变化的大部分原因。可能，非法药物使用的增加和抑郁症治疗的改善反映在 FARsch 的增加上。
