Introduction and Objectives: The incidence of device infection has increased over time and is associated with increased mortality in patients with cardiac implantable electronic devices (CIEDs). Gentamicin-impregnated collagen sponges (GICSs) are useful in preventing surgical site infection (SSI) in cardiac surgery. Nevertheless, to date, there is no evidence concerning their use in CIED procedures. Our study aims to determine the effectiveness of treatment with GICSs in preventing CIED infection., Methods: A total of 2986 adult patients who received CIEDs between 2010 and 2020 were included. Before device implantation, all patients received routine periprocedural systemic antibiotic prophylaxis. The study endpoints were the CIED infection rate at one year and the effectiveness of the use of GICSs in reducing CIED infection., Results: Among 1524 pacemaker, 942 ICD and 520 CRT implantations, CIED infection occurred in 36 patients (1.2%). Early reintervention (OR 9 [95% CI 3.180-25.837], p<0.001), pocket hematoma (OR 11 [95% CI 4.195-28.961], p<0.001), diabetes (OR 2.9 [95% CI 1.465-5.799], p=0.002) and prolonged procedural time (OR 1.02 [95% CI 1.008-1.034], p=0.001) were independent risk factors for CIED infection. Treatment with GICSs reduced CIED infections significantly ([95% CI -0.031 to -0.001], p<0.001)., Conclusions: The use of GICSs may help in reducing infections associated with CIED implantation., (Copyright © 2023.

Clinical decision-making requires synthesis of evidence from literature reviews focused on a specific theme. Evidence synthesis is performed with qualitative assessments and systematic reviews of randomized clinical trials, typically covering statistical pooling with pairwise meta-analyses. These methods include adjusted indirect comparison meta-analysis, network meta-analysis, and mixed-treatment comparison. These tools allow synthesis of evidence and comparison of effectiveness in cardiovascular research.
