Results of a regional study of modes of death associated with coronary artery bypass grafting
Why the study?
Does the rate of fatal heart failure explain the variation in surgeon-specific in-hospital mortality rates for patients undergoing CABG?
Population

Implication
Surgeon CABG mortality variation associates with fatal postoperative HF; hypothesis-generating for targeted perioperative strategies but leaves causal mechanisms and practice change open.
Structured PICO

P
Population
n=8,641 consecutive patients undergoing isolated coronary artery bypass grafting (CABG) in northern New England
I
Intervention
CABG performed by cardiothoracic surgeons in the highest risk-adjusted mortality tercile
C
Comparator
CABG performed by cardiothoracic surgeons in the lowest risk-adjusted mortality tercile
O
Outcome
In-hospital mortality and cause-specific mode of death (assigned by an end points committee using predetermined definitions)hard clinical
Variations in surgeon-specific CABG mortality rates are primarily driven by differences in rates of fatal post-operative heart failure, which cannot be explained by baseline patient characteristics.
