Cardiac implantable electronic device infection awareness - A European survey amongst implanting physicians

Abstract

Background and aims: Cardiac Implantable Electronic Device (CIED) infections pose significant mortality and morbidity despite optimal treatment. This survey aimed to understand whether and how the risk of CIED infection is assessed and mitigated in clinical practice in Europe, and to detect gaps with respect to EHRA recommendations.

Methods: An Expert Group of 8 European cardiologists with specific expertise across CIED therapy designed and distributed electronically a survey to a number of European Cardiologists.

Results: 302 physicians from 18 European countries responded to the survey. 288/302 (95%) physicians agreed that CIED-related infections represent a burden on healthcare resources and are associated with significant morbidity and mortality. 285/302 respondents (94%) primarily assess the risk of CIED infections by only evaluating the patient's clinical profile (137/302, 46%) or with the support of a risk score (148/302, 49%). Intravenous antibiotic prophylaxis is used by 282/302 (93%), followed by the implantation of the lowest number of leads possible (182/302, 60%), and by the use of an antibacterial envelope (173/302, 57%). 230/302 respondents (76%) declared that there is need for clear and concise guidelines and more sensitive risk-scores for CIED infection, to maximize the chances of preventative strategies.

Conclusions: This survey demonstrates a high level of awareness about the multifaceted issue of CIED infection, however, it also highlights an incomplete penetration of scoring systems for risk stratification owing to their perceived limitations, and detects a strong commitment to increase the effectiveness of preventative strategies.
