Surgical care improvement project and surgical site infections: can integration in the surgical safety checklist improve quality performance and clinical outcomes?

Introduction: The World Health Organization Surgical Safety Checklist (SSC) has been shown to decrease surgical site infections (SSI). The Surgical Care Improvement Project (SCIP) SSI reduction bundle (SCIP Inf) contains elements to improve SSI rates. We wanted to determine if integration of SCIP measures within our SSC would improve SCIP performance and patient outcomes for SSI.

Methods: An integrated SSC that included perioperative SCIP Inf measures (antibiotic selection, antibiotic timing, and temperature management) was implemented. We compared SCIP Inf compliance and patient outcomes for 1-y before and 1-y after SSC implementation. Outcomes included number of patients with initial post-anesthesia care unit temperature <98.6°F and SSI rates according to our National Surgical Quality Improvement Program data.

Results: Implementation of a SCIP integrated SSC resulted in a significant improvement in antibiotic infusion timing (92.7% [670/723] versus 95.4% [557/584]; P < 0.05), antibiotic selection (96.2% [707/735] versus 98.7% [584/592]; P < 0.01), and temperature management (93.8% [723/771] versus 97.7% [693/709]; P < 0.001). Furthermore, we found a significant reduction in number of patients with initial post-anesthesia care unit temperature <98.6°F from 9.7% (982/10,126) to 6.9% (671/9676) (P < 0.001). Institutional SSI rates decreased from 3.13% (104/3319) to 2.96% (107/3616), but was not significant (P = 0.72). SSI rates according to specialty service were similar for all groups except colorectal surgery (24.1% [19/79] versus 11.5% [12/104]; P < 0.05).

Conclusion: Implementation of an integrated SSC can improve compliance of SSI reduction strategies such as SCIP Inf performance and maintenance of normothermia. This did not, however, correlate with an improvement in overall SSI at our institution. Further investigation is required to determine other factors that may influence SSI at an institutional level.
