Understanding and Reducing Diagnostic Error– Diagnostic error in medicine has been estimated at about 10% or more from claims data, autopsies, and retrospective studies. A growing body of literature on this topic is reviewed by the acknowledged expert Mark Graber who has studied, lectured and published extensively on the subject. Graber dissects the systems-related and cognitive sources of error and proposes a number of concrete things physicians can do to reduce diagnostic error in their practice.
Define systems-based and cognitive sources of diagnostic error and explain their relationship.
Give an example of premature closure and of availability bias as sources of cognitive error in diagnosis.
Identify several actions a physician can take to reduce diagnostic error due to systems problems.
Describe how to undertake a root cause analysis of a diagnostic error.
