Percentage of adult colectomy cases that had a surgical site infection within 30 days after surgery as defined and reported by the Michigan Surgical Quality Collaborative (MSQC).

Surgical site infections (SSIs) occur at the site of surgical incision and can lead to serious complications resulting in prolonged hospital stays, increased healthcare costs and mortality. Hyperglycemia, hypothermia, and inadequate antibiotic prophylaxis can all lead to increased SSIs and are modifiable factors in intraoperative care.  Anesthesia providers play an integral role in reducing the risk of patients developing an SSI.^1-6 

Out of room time on day of surgery through 30 days after surgery

• Cases that match with an MSQC registry case as determined by MSQC Case Matching 
• Case was a colectomy procedure as determined by MSQC Procedure Group (value code: 3)

Cases that do not match with an MSQC case as determined by MSQC Case Matching

Case did not have a surgical site infection within 30 days after surgery as defined by MSQC Postoperative Outcomes (value codes: 1, 2, 3)

 MPOG has partnered with the Michigan Surgical Quality Collaborative (MSQC) to merge MPOG and MSQC data in order to report SSI outcomes to Michigan hospitals participating with both collaboratives. MSQC is a Collaborative Quality Initiative funded by Blue Cross Blue Shield of Michigan (BCBSM) and committed to enhancing surgical quality and clinical outcomes for patients undergoing general surgery. MSQC maintains a data repository of perioperative data, abstracted and validated by nurses throughout Michigan. A stratified sampling methodology is used to capture a representative portion of surgical cases. This involves a repeating and rotating 8-day cycle over a 12-month period and is limited to a subset of surgical CPT codes. MSQC classifies SSIs in three categories: Superficial Incisional, Deep Incisional, and Organ/Space. MSQC cases were matched to the corresponding MPOG case using the matching algorithm specified in the MSQC Case Matching phenotype. Only MPOG cases that were successfully matched to an MSQC case were included in the denominator for this measure. Both the rate of SSI infection as well as the raw count are reported in the MPOG QI Reporting Tool. 

• Surgical Site Infections (SSIs) are assigned to the anatomic site of the Principal Operative Procedure.
• Principal Operative Procedure is defined by MSQC as the ‘index’ procedure that meets the inclusion criteria for colectomy based on CPT codes. Cases must be performed in an operating room or ‘hybrid’ room to be considered as the Principal Operative Procedure. 
• If multiple procedures are performed during a case, and more than one CPT code meets the MSQC inclusion criteria for a case, the following priority algorithm is applied to determine the Principal Operative Procedure (highest priority listed first):
  • The CPT associated with the primary disease/diagnosis that led to surgery (colectomy if primary diagnosis was colon cancer)
  • By the organ that provided the more ‘acute’ indication for surgery as described in the operative report
  • May be the most complex procedure performed by the operating team during the visit to the operating room
  • The procedure is listed on the Appendix A-B: MSQC-included CPT codes and CPT enabled variables list
  • The surgeon who scheduled the procedure or the surgeon treating the patient for the main preoperative diagnosis
• For procedures with multiple incision sites and/or multiple SSIs found, only the deepest tissue level involved is reported once in the 30 days after surgery. For example, if one laparoscopic incision meets criteria for a superficial incisional SSI and another meets criteria for a deep incisional SSI, only the deep incisional SSI will be reported to MSQC.
• Other details resulted in the case list include:
  • MSQC Procedure Type 
  • Type of Surgical Site Infection as determined by MSQC Postoperative Outcomes 
  • SSI Occurrence Timeframe:
    • 0-7 Days Postop = 1 (early complication)
    • 8-30 Day Postop = 2 (late complication)
• More details regarding MSQC SSI definitions are described in the Appendix (copied directly from the 2025 MSQC Program Manual)
