Review Comparative Study
Calculating kappas from adjusted data improved the comparability of the reliability of triage systems: a comparative study.
It is difficult to compare the reliability of triage systems with the kappa statistic. In this article, a method for comparing triage systems was developed and applied to previously conducted triage reliability studies. ⋯ When comparing triage systems with different numbers of categories, one should report both the normal and quadratically weighted kappa. Calculating normal kappas from previously conducted triage reliability studies revealed substantial theoretical differences in interrater reliability of triage systems than previously reported.
