  • Title: Acceptance among and impact on dental practitioners and patients of American Heart Association recommendations for antibiotic prophylaxis.
    Author: Lockhart PB, Hanson NB, Ristic H, Menezes AR, Baddour L.
    Journal: J Am Dent Assoc; 2013 Sep; 144(9):1030-5. PubMed ID: 23989842.
    Abstract:
    BACKGROUND: The 2007 American Heart Association (AHA) guidelines for the prevention of infective endocarditis (IE) called for a major reduction in the number of patients recommended for antibiotic prophylaxis (AP) and redefined the dental procedures considered to put these patients at risk of acquiring the infection. The purpose of the authors' study was to determine the acceptance of these changes among and the impact of the changes on dentists and their patients. METHODS: The authors sent a survey to a random sample of 5,500 dentists in the United States. RESULTS: Ninety-five percent of the 878 respondents indicated that they saw patients who receive AP. More than 75 percent were either satisfied or very satisfied with the AHA guidelines, and the respondents indicated that they believed almost three-quarters of their patients also were pleased. Seventy percent of dentists, however, had patients who took antibiotics before a dental procedure even though the guidelines no longer recommend it. CONCLUSIONS: Acceptance of the 2007 guidelines appears to be high, but controversy remains. Additional scientific data are needed to resolve these issues. PRACTICAL IMPLICATIONS: The 2007 AHA guidelines have greatly simplified the identification of patients who need AP for dental procedures, given that, in general, far fewer people with cardiac abnormalities are considered to be at risk as a result of invasive procedures. Some physicians, however, continue to prescribe antibiotics for some patients whom the AHA no longer considers to need them. Patients also may choose to continue this practice themselves. There is ongoing controversy surrounding this common clinical question in dental practice, and the next guidelines from the AHA may change on the basis of data from future clinical studies.
