Papers Presented to the Vascular and Endovascular Surgery Society - 26th Annual Winter Meeting, January 2016The Impact of Surgical Care Improvement Project Measures on In-Hospital Outcomes following Elective Vascular Procedures

BackgroundAs part of the Surgical Care Improvement Project (SCIP), a national quality partnership of organizations including the Centers for Medicare and Medicaid Services and the Centers for Disease Control and Prevention implemented several perioperative guidelines regarding antibiotic, venous thromboembolism (VTE), and beta-blocker prophylaxis for surgical patients. We evaluated the effect of SCIP on in-hospital surgical site infections (SSI), graft infections, VTE, myocardial infarctions (MIs), cardiac complications, mortality, and length of stay following elective major vascular surgery.MethodsUsing International Classification of Diseases, Ninth Revision (ICD-9) diagnostic and procedure codes, we identified elective open abdominal aneurysm repair (OAR), endovascular aneurysm repair (EVAR), carotid endarterectomy (CEA), major lower extremity amputation, and lower extremity bypass (LEB) procedures in the National Inpatient Sample from 2000 to 2012. Logistic regression and generalized linear models controlling for covariates were used to compare postoperative in-hospital outcomes before and after SCIP implementation (pre-SCIP era 2000-2005 versus post-SCIP era 2009-2012).ResultsIn the post-SCIP era, the rate of in-hospital SSI following OAR increased from 1.0% to 1.6% (P < 0.05). Nonetheless, there were improvements in in-hospital SSI (in EVAR and CEA), graft infections (in OAR, EVAR, and LEB for tissue loss), VTE (in CEA), MI (in EVAR and LEB for tissue loss), cardiac complication (in all procedures except OAR), mortality (in EVAR, CEA, major lower extremity amputation, and LEB for tissue loss), and length of stay (in all procedures except OAR) (all P < 0.05). However after adjusting for covariates, SCIP was only associated with reducing SSI in CEA and major lower extremity amputation, graft infections in OAR and LEB for tissue loss, VTE in LEB for claudication or rest pain, mortality in OAR, and length of stay in all procedures except EVAR and CEA.ConclusionsImplementation of SCIP measures was associated with slight improvements in a few in-hospital outcomes following vascular procedures. Additional measures that are more specific to the clinical and technical challenges of treating vascular disease may be more effective for improving the management of vascular patents.
