This article reports on adopting Gustafson's multiattribute utility method to develop a specific momentary severity index (vis-à-vis severity over time) for nontraumatic chest pain patients. A panel of physicians identified an appropriate set of indicators for the index. Three mathematic models were generated on the basis of these indicators with each model predicting no less than 81% of the variance in overall scores of 96 simulated patients with chest pain. High interrater reliability (0.94) was demonstrated. Congruent validity coefficients between the three model scores and the overall scores vary between 0.71 and 0.92 depending on how the panel physicians are grouped. Results indicate the feasibility of simulating physician judgments regarding patient severity in chest-pain-related cases.
本文报道了采用古斯塔夫森的多属性效用方法，为非创伤性胸痛患者开发一个特定的瞬时严重程度指数（相对于随时间的严重程度）。一组医生确定了该指数的一组合适指标。基于这些指标生成了三个数学模型，每个模型对96例模拟胸痛患者的总体得分方差的预测率均不低于81%。结果显示了较高的评分者间信度（0.94）。根据对专家小组医生的分组方式不同，三个模型得分与总体得分之间的一致性效度系数在0.71至0.92之间变化。结果表明，在与胸痛相关的病例中模拟医生对患者严重程度的判断是可行的。
