Surgical Site Infections (SSIs)

Presented below are data for surgical site infections associated with coronary artery bypass graft surgery (CABG) and total knee replacement surgery (KPROs) using the Standardized Infection Ratio (SIR). Superficial and secondary surgical site infections are not included in the summary data below. Statewide summaries of surgical site infection data arranged by surgical procedure (CABG, KPRO) and hospital are also included.

Statistical Significance
