Key result
Cardiologists were significantly more likely than dentists to correctly prescribe amoxicillin prophylaxis for infective endocarditis before oral procedures (88.7% vs 74.8%, PR 1.21).
Why the study?
Antibiotic prophylaxis for bacterial endocarditis before invasive procedures has long been recommended in predisposing cardiac conditions, but contemporary guidelines worldwide have proposed changes.
Cross-Sectional (n=613)
Relative Risk: 1.21 (95% CI 1.09–1.34)
Absolute Event Rate: 88.7% vs 74.8%
p-value: p=<0.001
Cardiologists and dentists in Brazil frequently prescribe antibiotic prophylaxis for both high- and moderate-risk patients before oral procedures, highlighting partial knowledge of current international guidelines and a need for continuous education.
May warrant targeted dentist education on IE prophylaxis; leaves open whether knowledge gaps affect actual prescribing or outcomes.

Brandão et al. (2023) conducted a cross-sectional in Infective endocarditis prophylaxis (n=613). Cardiology specialty vs. Dentistry specialty was evaluated on Correct prescription of amoxicillin (2 g, orally, 30-60 minutes before procedure) (PR 1.21, 95% CI 1.09-1.34, p=<0.001). Cardiologists were significantly more likely than dentists to correctly prescribe amoxicillin prophylaxis for infective endocarditis before oral procedures (88.7% vs 74.8%, PR 1.21).
