Key result
Attending anesthesiologist, procedure type, and case duration were the largest sources of anesthetic drug cost variation, with attending anesthesiologists altering costs by -$41.25 to +$95.67.
Observational (n=4,856)
Yes
The overall cost of anesthetic drugs per case is small, suggesting that cost-saving interventions focused on attending anesthesiologists' clinical practice may yield negligible savings.

Modest anesthesiologist-attributable drug cost variation implies negligible intervention savings; leaves open whether system-level factors drive meaningful perioperative savings.
Wanderer et al. (2017) conducted an observational in Inpatient surgical procedures (n=4,856). Attending anesthesiologist, case type, and procedure duration was evaluated on Logarithmically transformed case cost. Attending anesthesiologist, procedure type, and case duration were the largest sources of anesthetic drug cost variation, with attending anesthesiologists altering costs by -$41.25 to +$95.67.
