Preoperative interventions improve outcomes for patients after coronary artery bypass surgery (CABG).


To reduce mortality for patients undergoing urgent CABG.


Eight centers implemented preoperative aspirin and statin, preinduction heart rate less than 80/min, hematocrit greater than 30%, blood sugar less than 150 mg/dL (8.3 mmol/L), and delayed surgery at least 3 days after a myocardial infarction. Data were collected on the last 150 isolated, urgent CABGs at each center (n=1200). A "bundle" score of 0 to 100 was calculated for each patient to represent the percentage of interventions used.


Scores ranged from 33 to 100. About 56% of patients had a perfect score. Crude mortality and composite rates were lower in patients with higher scores, but once adjusted for patient and disease characteristics, the difference in scores was not significant. Higher scores were associated with shorter intubation: 6.0 hours (score 100), 8.0 hours (score 80-99), 8.4 hours (score<80) (log-rank P<.001). Median length of stay was shorter for patients with higher scores: 5 days (score 100), 6 days (scores 80-99), and 6 days (scores <80) (log-rank P<.001).


Implementation of interventions to optimize patients' "readiness for surgery" is associated with shorter intubation times and shorter hospital stays after CABG.
