Lecture 5: Reviewing prior studies to reduce errors
Goal: Understand how reviewing prior imaging can influence interpretation and reduce diagnostic errors
Recommended reading
Lecture 5 Pretest

In the 2013 retrospective study by Kim and Mansfield about types of diagnostic error, the percentage of errors attributed to not reviewing prior imaging studies was:

  1. 5%
  2. 22%
  3. 0.9%
  4. 2%

Which of the following is NOT a contributing factor to radiologists failing to review relevant prior studies?

  1. Prior examination was performed at an outside institution
  2. Lack of evidence that reviewing prior studies reduces errors
  3. Failure of a PACS server to retrieve prior exams at the time of interpretation
  4. PACS automatically selects prior studies for comparison

Which of the following types of cognitive bias can occur when a radiologist reads the prior imaging report before reviewing an imaging study?

  1. Hindsight bias
  2. Availability bias
  3. Alliterative bias
  4. Anchoring bias

According to the ACR’s practice parameter for the performance of chest radiography, a radiologist should:

  1. Review the most recent prior chest x-ray
  2. Review all recent chest x-rays
  3. Review all prior chest x-rays
  4. Review all pertinent imaging studies

Among the following options, the most common type of error is when:

  1. The finding is identified and interpreted correctly, but the message fails to reach the ordering provider
  2. The finding is identified but attributed to the wrong cause
  3. The finding is missed because of failure to continue to search for additional abnormalities after the first abnormality was found
  4. The finding is missed because of failure to consult prior radiologic studies or reports
