目的 评价结合两种不同决策支持方法(贝叶斯网络和自然语言理解系统)的计算机化决策支持系统诊断肺炎患者的性能。 设计 使用前瞻性临床研究数据进行的评价研究。 患者 所有18岁及以上的患者,他们在三级护理机构的急诊科就诊,并且在就诊期间可以获得胸部X线检查报告。 方法 计算机化的决策支持系统使用两个系统提供的信息计算肺炎的概率。结果指标为受试者工作特征曲线下面积、敏感性、特异性、预测值、似然比和试验有效性。 结果 在3个月的研究期间,共有742例患者(45例肺炎)。单独贝叶斯网络的受试者工作特征曲线下面积为0.881(95% CI:0.822,0.925),贝叶斯网络与自然语言理解系统组合的受试者工作特征曲线下面积为0.916(95% CI:0.869,0.949)(p=0.01)。 结论 组合处理以不同数据格式存储的信息的决策支持方法可以提高计算机化决策支持系统的性能。
OBJECTIVE To evaluate the performance of a computerized decision support system that combines two different decision support methodologies (a Bayesian network and a natural language understanding system) for the diagnosis of patients with pneumonia. DESIGN Evaluation study using data from a prospective, clinical study. PATIENTS All patients 18 years and older who presented to the emergency department of a tertiary care setting and whose chest x-ray report was available during the encounter. METHODS The computerized decision support system calculated a probability of pneumonia using information provided by the two systems. Outcome measures were the area under the receiver operating characteristic curve, sensitivity, specificity, predictive values, likelihood ratios, and test effectiveness. RESULTS During the 3-month study period there were 742 patients (45 with pneumonia). The area under the receiver operating characteristic curve was 0.881 (95% CI: 0.822, 0.925) for the Bayesian network alone and 0.916 (95% CI: 0.869, 0.949) for the Bayesian network combined with the natural language understanding system (p=0.01). CONCLUSION Combining decision support methodologies that process information stored in different data formats can increase the performance of a computerized decision support system.
