Area of Science:

  • Medical Education
  • Cognitive Science in Medicine
  • Surgical Diagnostics

Background:

  • Expert diagnosticians utilize pattern recognition for clinical problem-solving.
  • Developing diagnostic recognition of common surgical issues is vital for undergraduate surgical training.
  • A surgical pattern recognition examination (PAT) was created to evaluate diagnostic recognition in clerkship students.

Purpose of the Study:

  • To develop and validate a novel examination assessing surgical diagnostic ability.
  • To evaluate the reliability and validity of the surgical PAT for third-year medical students.

Main Methods:

  • Surgical faculty identified 18 diagnoses for 20 presenting complaints.
  • Distinctive patient descriptions were created for each diagnosis.

  • A 200-item examination was developed covering 20 presenting complaints.

    • Main Results:

    • The PAT was administered to 77 clerkship students, with scores ranging from 33% to 90% (mean 65%).
    • PAT scores demonstrated a high correlation with National Board of Medical Examiners (NBME) Surgery Subject Examination (SSE) scores.
    • Senior residents outperformed junior residents on the PAT, and performance improved with clinical experience.

    Conclusions:

    • The surgical PAT is a reliable and valid assessment tool for diagnostic ability.
    • The examination effectively measures diagnostic recognition skills in third-year medical students.
    • The PAT contributes to improving undergraduate surgical education by assessing key diagnostic competencies.
