The Australian National Non-Acute Inpatient Project has produced a casemix classification system for non-acute inpatients (NAIP). The daily classification has 19 final classes which bring together descriptions of a patient's clinical type (from admission diagnosis) and functional ability (from automated nursing care plans). Data on salary cost relating to care of 786 patients were collected at three large metropolitan teaching hospitals for six months during 1991, yielding a total sample of 15,013 non-acute bed-days. The NAIP classification was built from first principles, combining clinician input and statistical testing using an analysis of variance model (PC Grouper). Overall variance reduction on the full set of 15,013 records was 26.15 per cent.
澳大利亚国家非急性住院患者项目已经制定了一个针对非急性住院患者的病例组合分类系统（NAIP）。每日分类有19个最终类别，这些类别将患者的临床类型描述（来自入院诊断）和功能能力描述（来自自动护理计划）整合在一起。1991年期间，在三家大型都市教学医院收集了与786名患者护理相关的薪资成本数据，为期六个月，产生了总共15,013个非急性住院日的样本。NAIP分类是从第一原理构建的，结合了临床医生的输入和使用方差分析模型（PC Grouper）的统计测试。在全部15,013条记录上总体方差减少了26.15%。
