1233. Leveraging Informatics to Evaluate and Sustain Improvements in Peri-Operative Antimicrobial Prophylaxis Achieved Under the Surgical Care Improvement Project (SCIP)

Abstract

Abstract Background The Surgical Care Improvement Project (SCIP) was a national quality improvement program designed to improve peri-operative outcomes. The SCIP Program included several guideline-based antimicrobial stewardship measures, including discontinuation of antibiotics within 48 hours of skin closure for cardiac surgeries (INF-3). INF-3 was retired at the end of 2015; since this time, no systematic tools have been developed to support ongoing quality assessments. Methods We developed a retrospective, national cohort of cardiac surgeries in the national VA healthcare system during the period from 2010-2015 and merged these data with data from the VA External Peer Review Program, which included manually-assessed SCIP metrics, including INF-3. We electronically re-created the SCIP program by mapping exclusion criteria and developing code to assess the duration of post-operative antimicrobial use (Table 1). Among the manually-adjudicated cohort, we then iteratively refined the electronic tool until pre-specified criterion validity were achieved. After development, INF-3 compliance as assessed manually and by the objective informatics tool were compared. Results During the study period, 11,361 cardiac surgeries representing 26 VA facilities met inclusion criteria. The overall estimated compliance rate was 97.7% in the EPRP-reviewed cases (N=11,361) and 95.9% as-assessed by the informatics tool (N=9,561 cases); facility quality rankings using both methods were similar but not exactly the same (Figure 1). Facility-level compliance trends were similar using both measurement methodologies and the correlation between the two measures was high (r=0.69); however, the informatics tool consistently estimated compliance to be approximately 1.9% lower than manually reviewed cases (Figure 2). As estimated by the manual review program, 16 facilities (61.5%) achieved >97% compliance rates versus 9 facilities (34.6%) as estimated by the informatics tool. Figure 2. Facility-Level Compliance with INF-3 as Measured by Manual Review versus via Objective Electronic Tool Conclusion We developed a comprehensive, objective informatics tool for assessing ongoing compliance with SCIP INF-3. The tool can be applied in future investigations to assess the sustainability of practice changes achieved under the SCIP program and to identify areas for future improvement.
