Why the study?
Does preoperative anemia increase adverse outcomes in patients undergoing elective cranial surgery?
Population
6576 patients undergoing elective cranial surgery between 2006 and 2011 identified from the National…
Comparison
Preoperative moderate to severe anemia or mild… vs No preoperative anemia (propensity score matched)
Design
Cohort
Follow-up
≤ 30 days
Key result
Preoperative moderate-severe (OR 1.8; 95% CI 1.1-2.8) and mild anemia (OR 1.5; 95% CI 1.3-1.7) were associated with prolonged length of stay in patients undergoing elective cranial surgery.

Does not support routine preoperative anemia correction in elective cranial surgery; leaves open whether optimization reduces length of stay.

Does preoperative anemia increase adverse outcomes in patients undergoing elective cranial surgery?
Effect estimate: OR 1.8 (95% CI 1.1-2.8)
Preoperative anemia in elective cranial surgery is associated with prolonged hospital length of stay but not an overall increased risk for adverse outcomes or death.
Alan et al. (2013) conducted an observational in Elective cranial surgery (n=6,576). Preoperative anemia (moderate-severe or mild) vs. No anemia was evaluated on Prolonged length of stay (LOS) (OR 1.8, 95% CI 1.1-2.8). Preoperative moderate-severe (OR 1.8; 95% CI 1.1-2.8) and mild anemia (OR 1.5; 95% CI 1.3-1.7) were associated with prolonged length of stay in patients undergoing elective cranial surgery.
