Implication

Valve surgery wait times were associated with higher mortality than CABG; leaves open whether revised prioritization is warranted pending prospective data.

Structured PICO

Does waiting for cardiac valve surgery compared to isolated CABG increase the risk of death while waiting?

P
Population
29,293 consecutive patients scheduled for cardiac surgery (isolated CABG, isolated valve surgery, or combined procedures) between October 1991 and June 1995 across 9 cardiac surgical units in Ontario, Canada.
I
Intervention
Waiting for cardiac valve surgery or combined valve and CABG procedures
C
Comparator
Waiting for isolated CABG
O
Outcome
Death while waiting for surgeryhard clinical

Patients waiting for cardiac valve surgery have a significantly higher risk of death than those waiting for isolated CABG, highlighting the need for revised queuing guidelines.
