title: Measuring severity of illness: a reliability study.
abstract: For a critical examination of the output of a hospital and to compare patients across hospitals, it is essential to measure severity of illness along with case mix. This article describes a new severity-of-illness index that is generic and may be applied to almost all hospital patients. The reliability of this index and the time required for different types of raters to apply it are examined.
