2023 Duke ISCVID Diagnostic Criteria for Infective Endocarditis Calculator

  • 2023 Duke ISCVID Diagnostic Criteria for Infective Endocarditis
    This calculator helps clinicians classify the probability of infective endocarditis based on the updated 2023 Duke ISCVID diagnostic criteria.
  • Major Criteria
  • Typical microorganisms consistent with infective endocarditis from two separate blood cultures
  • Imaging evidence of endocardial involvement including echocardiography or cardiac CT
  • Minor Criteria
  • Predisposing heart condition or injection drug use
  • Fever equal or more than 38 Celsius
  • Vascular phenomena including emboli or intracranial hemorrhage
  • Immunologic phenomena including glomerulonephritis or Osler nodes
  • Microbiological evidence not meeting major criteria
  • 2023 Duke ISCVID Diagnostic Criteria for Infective Endocarditis Explanation and Clinical Context
    The 2023 Duke ISCVID criteria represent an updated and refined diagnostic framework for infective endocarditis incorporating advances in microbiology imaging and clinical epidemiology.

    The criteria classify cases into definite possible or rejected infective endocarditis based on combinations of major and minor clinical findings.
    Major criteria emphasize microbiological confirmation and objective imaging evidence of endocardial involvement.
    Minor criteria reflect host predisposition systemic manifestations and supportive microbiological data.
    This structured approach improves diagnostic accuracy supports early treatment decisions and facilitates standardized research reporting.
