Podcast # 481: Medical Errors and Cognitive Bias - The Emergency Medical Minute

Contributor: Peter Bakes, MD

Educational Pearls:

  • While there are many different types of medical error, one of the most common errors in emergency medicine is failure to diagnose
  • Systematic error in thinking that negatively affects judgement
  • Medical errors are often driven by cognitive biases, which include anchoring, attribution, and availability  
  • Anchoring bias occurs when early information leads to premature closure on a single diagnosis. There is subsequent failure to consider alternative diagnoses, even in the face of conflicting new data and test results.
  • Attribution bias occurs when assumptions about personal and medical characteristics are made about a specific group of people.
  • Availability bias occurs when recent experiences drive providers to over or under consider diagnoses.
