    Abstract:
    BACKGROUND: Cardiac implantable electronic device (CIED) infection is a major complication that is associated with increased morbidity and mortality. Recent data suggested a relationship between the antiseptic agent used for skin preparation at time of CIED procedure and risk for infection. METHODS: On April 30, 2011, we changed the antiseptic agent used for skin preparation at our tertiary care facility from chlorhexidine-alcohol to povidone-iodine for all CIED procedures. We retrospectively reviewed records of all patients who underwent CIED procedure 1 year before and after the change. CIED infection was defined as pocket or endovascular systemic infection that required removal within 1 year of the index procedure. We examined if the change affected the risk of CIED infection. RESULTS: A total of 2,792 patients underwent 2,840 CIED procedures; 1,748 (61.5%) had implantable cardioverter defibrillator procedures and 1,092 (38.4%) had permanent pacemaker procedures. Chlorhexidine-alcohol agent was used in 1,450 (51.1%) procedures, and povidone-iodine agent was used in 1,390 (48.9%). After 1 year of follow-up, 31 patients (1.09%) developed CIED infection that required system removal. The 1-year infection rate was 1.1% among both antiseptic agent groups and there were no significant differences in the infection presentations among both groups (P = 0.950). Multivariate Cox proportional hazards regression model showed that risk factors for infection within 1 year included age, diabetes, and African American race. CONCLUSION: In one large cohort of patients undergoing CIED procedures, the antiseptic agent used for skin preparation (chlorhexidine-alcohol vs povidone-iodine) was not associated with increased risk of developing CIED infection.
