Nonurgent CABG prioritization was associated with higher preoperative mortality; leaves open whether urgency-based queuing affects survival in broader settings.
Does nonurgent priority categorization (longer delays) increase preoperative mortality in patients awaiting CABG compared to semiurgent categorization?
Queuing according to urgency of treatment contributes to a higher proportion of CABG candidates dying before surgery from all causes in the nonurgent group due to longer wait times.
Sobolev et al. (2006) studied this question.
