Prevention of bacterial endocarditis in Germany.

Abstract

The goal of this study was to assess the current practice of endocarditis prophylaxis in Germany. We conducted a survey using a standardized questionnaire, which was sent to 100 hospital cardiologists, to 430 cardiologists in office practice and to 389 dentists and oral surgeons. In addition, 364 patients with valvular or congenital heart disease were interviewed in our outpatient clinic. Seventy five percent of cardiologists informed their patients by both written and oral instructions. Half recommended the use of penicillin, according to the German Society of Cardiology, while the rest followed recommendations of other societies. Sixty-three percent of patients who had undergone a procedure requiring prophylaxis against bacterial endocarditis within the year prior to the questionnaire, had actually received it. This is higher than previously reported, but is far from acceptable. The indications for prevention of endocarditis, as seen by the dentists, deviated markedly from official recommendations. Although 77% administered antibiotics themselves, in only 57% did the type of prophylaxis applied correspond to one of the available recommendations. Recommendations on the prevention of bacterial endocarditis are not well known dentists and oral surgeons who perform procedures for which it is indicated. Further patient- and physician-oriented strategies are urgently needed to improve compliance with prevention of endocarditis in Germany.
