Background: Surgical site infections (SSIs) can be attributed to increased patient morbidity and mortality, prolonged hospital stays, and overall increased healthcare costs. The Surgical Care Improvement Project (SCIP) was implemented in 2002 but has made limited impact on SSI rates across our facilities, which has led to the creation of a bundled approach of current evidence-based strategies. Methods: In January 2019, a comprehensive SSI prevention bundle of strategies was implemented across a multihospital health system. The bundle was comprised of 8 interventions focusing on the preoperative, intraoperative, and postoperative continuum of care, and refining documentation in the electronic medical record. From January to September 2019 (preointervention period), data were collected from 7,163 adult inpatient and observation elective patients undergoing colon surgery (COLO), abdominal hysterectomy (HYST), hip arthroplasty (HPRO), knee arthroplasty (KPRO), and cardiac bypass graft (CBGB/CBGC). The preintervention period for SSI standardized infection ratios (SIRs) and retrospective review of process measures was set as January–December 2018 (postintervetnion period). Each process measure had outlined targets along with primary outcome measures of overall SSI SIRs and SIRs for each of the 5 reported procedure categories. SSIs were validated to meet CDC and NHSN surveillance case definitions. Secondary outcomes evaluated included length of stay (LOS), readmission rates, and mortality. Results: Overall SIR for all 5 monitored surgical categories decreased by 5% to 1.131 from January to September 2019, compared to SIR of 1.190 in 2018. Hip and knee arthroplasties demonstrated 40% and 38% reductions after the intervention, respectively. Completion of 7 or 8 interventions of the SSI bundle were correlated with lower readmission rates (P = .0488). When any portion of the bundle was used, this was correlated with shorter LOS (P < .0001). Adherence to standardized antimicrobial prophylaxis was associated with decreased mortality (P = .017), for all 5 surgical categories. Conclusions: With the implementation of a focused SSI reduction bundle, our institution has realized reductions in surgical readmissions, length of stay, and mortality. Additionally, SSI rates in certain procedure categories have shown marked improvement. The initial success of this bundle has garnered development of additional procedure focused supplemental strategies for the future year.
