Beta blocker therapy

What It Means
Percentage of selected surgical patients on beta-blocker therapy prior to admission who received a beta-blocker during the perioperative period. The perioperative period for this measure is defined as 24 hours prior to the surgical incision through discharge from the post-anesthesia care/recovery area.

Why It Is Important
For those patients on beta-blocker therapy, continuous beta-blocker therapy during the perioperative period has been shown to help reduce the occurrence of cardiac complications after surgery.
