Inpatient surgical care: timely antibiotic before heart valve surgery (IHA)

Antibiotics are medicines that can kill bacteria that cause infections. Infections are a possible complication of any surgical procedure. When patients receive antibiotics within one hour before surgery, their risk for wound infection is reduced.

About This Measure

This measure tracks the percentage of patients having open heart surgery, other than coronary artery bypass (CABG) surgery, who receive antibiotics at the right time, within one hour before surgery.  This measure includes many different types of surgeries on the heart, most of which are heart valve surgeries.

Note: Comparison data is not available for this measure. You can view results of other individual hospitals at


In this case, a higher number is better.
