Key result
Preoperative anemia was weakly associated with 30-day postoperative mortality (OR 1.24; 95% CI 1.10-1.40) after adjusting for suspected mediator variables.

Preoperative anemia should not yet alter management in noncardiac surgery; leaves open whether correction reduces mortality beyond comorbidities.
Cohort (n=574,860)
Yes
Does preoperative anemia increase 30-day postoperative mortality and morbidity in noncardiac surgical patients?
Odds Ratio: 1.24 (95% CI 1.1–1.4)
Preoperative anemia is only a weak independent predictor of 30-day postoperative mortality in noncardiac surgery, as much of the associated risk is driven by underlying baseline diseases.
Saager et al. (2013) conducted a cohort in Noncardiac surgery (n=574,860). Preoperative anemia vs. No preoperative anemia was evaluated on 30-day mortality (OR 1.24, 95% CI 1.10-1.40). Preoperative anemia was weakly associated with 30-day postoperative mortality (OR 1.24; 95% CI 1.10-1.40) after adjusting for suspected mediator variables.
