    Study Notes

    Contributors and Publication

    • Experts include Grubenhoff, Ilgen, Kotwal, Lane, Singhal, Trowbridge, and Sargsyan from top medical institutions.
    • AHRQ Publication No. 22-0047-2-EF released in September 2022 highlights diagnostic excellence.

    Importance of Diagnostic Excellence

    • Diagnostic excellence is vital for accurate, timely diagnoses while optimizing resources and patient experience.
    • More than 12 million U.S. adults experience diagnostic errors annually; about half may suffer serious harm.
    • Achieving diagnostic excellence necessitates collaboration between individual clinicians and healthcare systems.

    Concepts of Calibration

    • Calibration involves aligning diagnostic accuracy with corresponding confidence levels.
    • Miscalibration can lead to overconfidence or underconfidence, resulting in misdiagnoses or inefficient processes.

    Case Review Suggestions

    • Use electronic health records (EHRs) to create a follow-up list of patients for calibration activities.
    • To reduce hindsight bias, identify cases before knowing the outcomes.
    • Collaborate with informatics personnel to generate reports that meet specific calibration goals.

    Individual Case Learning

    • Review selected cases individually and reflect on diagnostic reasoning using a standardized tool.
    • Recommended time commitment for reviews is approximately 3-4 hours each quarter.

    Evaluating Diagnostic Process

    • The Revised Safer Dx Instrument consists of prompts (1-12) to assess various diagnoses stages.
    • Prompt 13 allows for an overall evaluation of missed diagnostic opportunities.

    Modified Fishbone Diagram

    • A tool to analyze diagnostic errors by identifying cognitive and system-level contributing factors.
    • Helps healthcare professionals dissect complex cases, paving the way for quality improvements.

    Examples of Diagnostic Errors

    • Delayed diagnosis examples include:
      • Colorectal Cancer: Initially misdiagnosed due to symptoms attributed to constipation; findings of weight loss and anemia were overlooked.
      • Pulmonary Emboli: Documented factors contributing to diagnosis delays.
      • Children's Vomiting: History-taking hampered by language barriers; required reevaluation of differential diagnosis after persistent symptoms.
