Outcomes After the Implementation of Practice Management Guidelines for the Treatment of Cardiovascular Implantable Device Pocket Infections

Abstract

BackgroundTreatment of cardiovascular implantable device pocket infections (CIDPIs) requires a multimodal approach that includes antimicrobials, device explantation, and local wound care. Our institution implemented a practice management guideline (PMG) to standardize the care of CIDPIs and engage our acute care surgeons in 2013. Our PMG includes wound culture, complete capsulectomy, pulse lavage, and the placement of a negative pressure wound therapy appliance at the time of device extraction. Forty-eight hours later, wounds are irrigated and closed in a delayed primary fashion over drains. Our objective was to compare the outcomes of patients who underwent device extraction before and after the implementation of the PMG for the treatment of CIDPIs. MethodsAn IRB-approved retrospective review of 155 patients at our institution from 2012 to 2015 who underwent device explantation. Evaluated outcomes measured included days from device explant to wound closure, and postoperative complications. Outcomes data were analyzed before (pre-PMG) and after (post-PMG) enactment of the PMG. ResultsFifty-eight patients (42 males; mean age 68 years) were managed prior to PMG implementation; 97 (72 males; mean age 67) were managed after. Mean days from device explantation to wound closure were compared (pre-PMG 6 ± 3.5 and post-PMG 2.8 ± 1.8), and time to closure was reduced by 3-d post-PMG implementation (P < 0.05). No increase in surgical site infection, hematoma, or unplanned return to operating room was demonstrated between groups (P < 0.05). ConclusionsThe implementation of a PMG for the management of CIDPIs is effective in reducing the number of days to pocket wound closure; acute care surgeons are well equipped to participate in this practice and improve patient outcomes.
