Patient Safety - Surgical Site Infections (SSIs)

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

Statistically significantly better than the national average or performing at the best possible rate

Not statistically significantly better or worse than the national average

Statistically significantly worse than the national average

Key	Description
117	Complete Reporting: Zero infections. Number of reported events is not significantly different than predicted
118	Complete Reporting: Zero infections. Number of predicted events too low to calculate a precise SIR
154	Complete Reporting: Number of predicted events too low to calculate a precise SIR
