Standardized infection ratio (SIR) and Adjusted Ranking Metric (ARM)of hospital-onset unique blood source MRSA Laboratory-identified events (LabID events) among all inpatients in the facility
Surgical patients who received prophylactic antibiotics consistent with current guidelines (specific to each type of surgical procedure).
Surgical patients whose prophylactic antibiotics were discontinued within 24 hours after Anesthesia End Time. The Society of Thoracic Surgeons (STS) Practice Guideline for Antibiotic Prophylaxis in Cardiac Surgery (2006) indicates that there is no reason to extend antibiotics beyond 48 hours for cardiac surgery and very explicitly states that antibiotics should not be extended beyond 48 hours even with tubes and drains in place for cardiac surgery.
