Background-Along with the rising use of cardiac implantable electronic devices (CIEDs), there has been a disproportional increase in the number of infections of such devices. Little is known about nonstaphylococcal CIED-related infections, which make up Ϸ10% to 30% of all CIED infections. Methods and Results-A retrospective review of hospital records of patients admitted with a CIED-related infection was conducted in 4 academic hospitals in Houston, Tex, between 2002 and 2009. Of the 504 identified patients with CIED-related infection, 80 (16%) had a nonstaphylococcal infection and were the focus of this study. The mean duration of CIED placement before infection was 109Ϯ27 weeks, whereas 44% had their device previously manipulated within a mean of 29.5Ϯ6 weeks. The mean duration of clinical symptoms before admission was 48Ϯ12.8 days. Furthermore, 13 patients (16%) presented with CIED-related endocarditis. Although not described in prior reports, we identified 3 definite and 2 suspected cases of secondary Gram-negative bacteria seeding of the CIED. Inappropriate antimicrobial coverage was provided in Ϸ50% of the cases with a mean period of 2.1 days. The overall mortality rate was 4%.
Conclusions-Nonstaphylococcal
