    Area of Science:

    • Cardiology
    • Medical Informatics
    • Pharmacology

    Background:

    • Digitalis administration requires expert knowledge of pharmacokinetics and patient-specific factors.
    • Clinical decision-making for digitalis therapy can be complex, especially in acutely ill patients.
    • Existing methods may not fully capture the nuances of digitalis therapy management.

    Observation:

    • A prototypical computer program was developed to emulate cardiologist expertise in digitalis administration.
    • The program constructs patient-specific models incorporating pharmacokinetic data and individual patient conditions.
    • It assesses therapeutic and toxic effects, modifying recommendations based on the evolving clinical status.

    Findings:

    • A clinical trial demonstrated the program's feasibility in managing acutely ill patients, including those sensitive to digitalis toxicity.

  • Patients who developed toxicity received higher digitalis doses than the program recommended.
  • The program's recommendations were associated with safer digitalis management.

    • Implications:

    • This automated clinical consultation approach shows potential for distributing expert knowledge in digitalis therapy.
    • It may enhance the consistency and safety of digitalis administration in clinical practice.
    • Further development could lead to wider adoption in patient care settings.
