Bundled skin antiseptic preparation for complex cardiac implantable electronic device infection: a propensity-score...

Cardiac implantable electronic device (CIED) infection, a major complication of a CIED implant procedure, can prolong hospitalization and cause mortality.

To evaluate the efficacy of a bundled skin antiseptic preparation for preventing infection after implantation of a complex CIED.

This study analysed 1163 consecutive patients who had received a bundled skin antiseptic preparation before CIED implantation from July 2012 to December 2017. According to the complexity of the CIED implant procedure, the patients were divided into a complex CIED group (N = 370) and a non-complex CIED group (N = 793). A complex procedure was defined as a pacemaker replacement, implantation of implantable cardioverter defibrillator and cardiac resynchronization therapy, device upgrade, or lead revision.

During a mean follow-up of 2.9 ± 1.7 years, CIED infection developed in 15 patients (1.3%), and the incidence of minor and major infection was 1.1% and 0.2%, respectively. The incidence of CIED infection did not significantly differ between the complex CIED group and the non-complex CIED group (1.1% vs 1.4%, respectively; non-significant). Multivariate analysis indicated that procedural complexity was not an independent predictor of CIED infection. After 2:1 propensity score matching, the matched non-complex CIED group and the matched complex CIED group still showed no significant difference in the incidence of CIED infection.

Bundled skin antiseptic preparation is an effective and widely applicable strategy for decreasing infection risk after a complex CIED implantation.
