DH = Denver Health; IH = Intermountain Health; VA SLC = Veterans Affairs Salt Lake City Health Care System; VVMC = Vail Valley Medical Center; CABG = coronary artery bypass grafting, HERNIA = herniorrhaphy, THA = total hip arthroplasty, TKA = total hip arthoplasty,
* More than one organism can be counted for a single SSI. Only identified organisms are counted.
Organisms categorized by surgical bed, so that other surgeries with SSI at the same site could not be easily differentiated.
