Romano et al developed a comorbidity index for patients undergoing surgery. Points are based on the assigned weight performed on studies using an analysis modeled after the studies by Charlson. The authors are from the University of California Davis School of Medicine, University of Mannitoba, and Duke University.
Outcomes:
(1) 1 year mortality following CABG surgery
(2) in-hospital complications following lumbar discectomy
