^aCapitalization indicates presence of SSI reduction bundle element, lower case abbreviation indicates component absence. + indicates “OR,” * indicates “AND,” and <-> indicates a configuration causally linked to the outcome

^bConsistency is the proportion of cases with a configuration as specified by the listed solution that manifests the desired outcome

^cCoverage is the proportion of all cases with the desired outcome who fit the specified solution configuration

^dFit is the product of consistency and coverage

Listed abbreviations are as follows:

SSI = Surgical site infection

OA = Oral antibiotics

WP = Wound protector utilization

RA = Redosing intravenous antibiotic prophylaxis

CIO = Chlorhexidine intra-operative skin preparation

RD = Removal of occlusive dressing on POD2

CDOS = Chlorhexidine skin preparation the day of surgery

IA = Initial intravenous prophylactic antibiotics

OD = Occlusive dressing placement

N = PACU normothermia

BP= Mechanical bowel preparation

GGC = Gown and glove change
