The clinical data contained in narrative patient documents is made available via grammatical and semantic processing. Retrievals from the resulting relational database tables are matched against a set of clinical descriptors to obtain clinical profiles of the patients in terms of the descriptors present in the documents. Discharge summaries of 57 Dept. of Digestive Surgery patients were processed in this manner. Factor analysis and discriminant analysis procedures were then applied, showing the profiles to be useful for diagnosis definitions (by establishing relations between diagnoses and clinical findings), for diagnosis assessment (by viewing the match between a definition and observed events recorded in a patient text), and potentially for outcome evaluation based on the classification abilities of clinical signs.
通过语法和语义处理可获取病历文档中包含的临床数据。从生成的关系数据库表中检索出的数据与一组临床描述符进行匹配，以根据文档中出现的描述符获得患者的临床概况。对57名消化外科患者的出院小结进行了这样的处理。然后应用因子分析和判别分析程序，结果表明这些概况有助于诊断定义（通过建立诊断与临床发现之间的关系）、诊断评估（通过查看定义与患者文本中记录的观察事件之间的匹配情况），并且基于临床体征的分类能力可能有助于结果评估。
