Siddiqui et al1 reported underutilization of perioperative β-blockers. We wish to confirm and extend their observation by demonstrating resistance to change.
We prospectively monitored the perioperative use of β-blockers, before and after an intervention among the medical staff, as a project of safety and quality at Hadassah University Hospital (a leading academic center in Jerusalem, Israel), following a recent recommendation2 by the Agency of Healthcare Research and Quality.
