Predictors for readmission risk were investigated in this study, which forms part of the Nordic Comparative Study on Sectorized Psychiatry.
Included were a total of 837 consecutive 'new' patients (not in contact with the psychiatric services for at least 18 months) admitted to in-patient stay during a period of 1 year to seven psychiatric hospitals in four Nordic countries.
Multivariate survival analyses showed that younger age predicted increased readmission risk. Stratifying on gender, diagnostic group and sector revealed a general pattern concerning age which was the only consistent main effect. Living alone and unemployed increased readmission risk in the non-psychosis group, while receipt of aftercare decreased readmission risk in the psychosis group. A curvilinear relationship was found between availability of psychiatric resources and readmission risk: an intermediate amount of resources was associated with increased risk.
Our findings support a hypothesis that readmission risk is multifactorially determined and that interactions have to be considered.
本研究调查了再入院风险的预测因素，该研究是北欧精神科分区比较研究的一部分。
纳入了北欧四个国家七家精神病医院在1年期间连续收治的837名“新”患者（至少18个月未接触过精神科服务）。
多变量生存分析显示，年龄较小预示着再入院风险增加。按性别、诊断组和分区进行分层后发现，年龄呈现出一种总体模式，这是唯一一致的主要影响因素。在非精神病组中，独居和失业会增加再入院风险，而在精神病组中，接受后续护理则会降低再入院风险。研究发现精神科资源的可获得性与再入院风险之间存在曲线关系：中等数量的资源与风险增加相关。
我们的研究结果支持这样一种假设，即再入院风险是由多种因素决定的，必须考虑各种相互作用。
