ABSTRACT
BACKGROUND: Infective endocarditis (IE) is a rare but particularly serious disease. It frequently requires surgical treatment with cardiac valve replacement. In-hospital mortality is very high. The guidelines of the Society of Infectious Pathology of French Language (SPILF) for the prevention of infective endocarditis of at-risk patients were updated in 2002. They recommended a bi-annual oral health follow-up and antibiotic prophylaxis for invasive sequences of care for high-risk patients. The objective of the study was to assess the application of the guidelines. METHODS: Using databases and medical files of self-employed persons insured by compulsory national health insurance in the Alps, we studied from January 2001 to December 2002 the oral ambulatory follow-up of patients with permanent health insurance for valvular heart disease or congenital heart disease. RESULTS: Among the 260 patients with valvular heart disease or congenital heart disease, 125 (48.1%) presented medical claims for at least one dental treatment. Antibiotic prophylaxis was found in 15.8% of the invasive sequences of care for high-risk patients. The prescribed antibiotic was amoxicillin in 90% of the cases. CONCLUSION: Guidelines are seldom applied. Public and practitioner awareness should be improved to promote oral health: patients should regularly consult their dentist, and practitioners should follow the guidelines for the prevention of infective endocarditis.
