The present paper explores the rationale for the development of severity indices and the role such indices can play in various research and evaluation situations. Concrete examples from Emergency Medical Services research and evaluation settings are used to illustrate the potential shortcomings of designs that fail to incorporate measures of severity. A short critical review of existing indices is presented, and the ways that the indices can be refined and improved, and better used to evaluate emergency care, are summarized.
本文探讨了严重程度指数发展的基本原理以及这些指数在各种研究和评估情境中所能发挥的作用。通过紧急医疗服务研究和评估环境中的具体例子，来说明未纳入严重程度测量的设计可能存在的潜在缺陷。对现有指数进行了简短的批判性回顾，并总结了改进和完善指数以及更好地用于评估急诊护理的方法。
