Risk Ratio of Postoperative Infections by Adherence to SCIP Prevention Measures and Volume

Measure*	Hospital Data†‡	Patient Data†§
SCIP INF-1 adherence	0.98 (0.70-1.38)	0.83 (0.61-1.15)
SCIP INF-2 adherence	0.93 (0.66-1.32)	1.02 (0.74-1.42)
SCIP INF-3 adherence	0.74 (0.52-1.04)	1.21 (0.88-1.67)
SCIP INF-6 adherence	1.35 (0.94-1.92)	0.93 (0.67-1.28)
SCIP VTE-1 adherence	0.98 (0.68-1.42)	0.92 (0.66-1.29)
SCIP VTE-2 adherence	1.91 (1.31-2.79)	1.50 (1.07-2.12)
Hospital case volume	0.64 (0.44-0.93)	1.05 (0.75-1.47)

^*Adherence was based on whether hospital compliance was lower or higher than the median value of respective SCIP measure compliance or case volume. INF-1 indicates that the prophylactic antibiotic was received within one hour prior to surgical incision; INF-2, that prophylactic antibiotics were recommended for the specific surgical procedure; INF-3, that prophylactic antibiotics were discontinued within twenty-four hours after surgery end time; INF-6, that appropriate surgical site hair removal was done or surgical site hair removal was not required; VTE-1, that patients having surgery had recommended VTE prophylaxis ordered; and VTE-2, that patients having surgery received appropriate VTE prophylaxis within twenty-four hours before surgery to twenty-four hours after surgery.

^†The values are given as the adjusted OR with the 95% CI in parentheses.

^‡Another significant factor was teaching hospitals (p = 0.004).

^§Another significant factor was admission type (p < 0.0001), adjusted additionally for sex (p = 0.1) and comorbidity (p = 0.1).
