SSI Rate and Cost by Type of SSI

	Baseline Rate n=232 (%)	Post-Intervention Rate n=555 (%)	OR [90%CI]	p-value	Average Cost/SSI-related Readmission	Average Cost/SSI	Amount Saved
Incisional^*	22 (9.5)	33 (5.9)	0.60 [0.38–0.97]	0.04	$14,676	$1,631	$30,989
Superficial	18 (7.8)	29 (5.2)	0.66 [0.39–1.09]	0.09	$14,527	$1,038	$14,527

OSI	9 (3.9)	13 (2.3)	0.59 [0.29–1.23]	0.12	$58,937	$58,937	$471,499

As incisional SSI represents a combination of superficial and deep SSI, rates and costs associated with incisional SSI were not included in overall calculations. Only data related to superficial, deep and OSI SSI were included in overall calculations.

^**

Superficial or deep SSI could be present with OSI and were not considered mutually exclusive when calculating the overall SSI rate
