NICE and antibiotic prophylaxis to prevent endocarditis

Abstract

Infective endocarditis is a devastating disease with high morbidity and mortality. The link to oral bacteria has been known for many decades and has caused on going concern for dentists, patients and cardiologists. Good oral hygiene has long been advocated to prevent endocarditis. Before 2008, antibiotic prophylaxis before invasive dental procedures was also an important strategy for preventing infective endocarditis for patients at risk of the disease in the UK, and still is in most other countries of the world. In 2008, however, NICE published new guidance recommending that antibiotic prophylaxis in the UK should cease. At the time this was a highly controversial decision. New data suggests that there has been a significant increase in the incidence of infective endocarditis since the 2008 guidelines. The 2008 guidance is being reviewed and draft new guidance is being put out for public consultation. This article discusses the issues raised by the new data and the questions that should be addressed in the review and public consultation.
