Caution against relying on code-based severity measures for CABG mortality prediction; leaves open confounding by postoperative complications.
Do code-based severity measures predict in-hospital deaths differently than clinical severity measures in CABG patients?
While code-based severity measures show better statistical prediction of in-hospital CABG mortality than clinical measures, this may be confounded by the inclusion of postoperative complications in the coding.
Iezzoni et al. (1998) studied this question.
