- for every 1000 primary care visits, there are approximately 20 diagnostic errors, from which 1 patient will seek unplanned medical help within 2 weeks
About 75% of diagnostic errors have a cognitive component.(5) The two overarching cognitive components are:
(i) the tendency to seek only as much information as necessary to form an initial clinical impression, and (ii) the tendency to stick with the initial impression even as new information becomes available.
he failure to consider alternative diagnoses after the initial impression is formed
Premature closure
the tendency for clinicians to stick with the initial impression even as new information becomes available
anchoring,
anchoring bias = inadequate adjustment of probabilities as new disconfirming information becomes available.
the tendency to selectively seek information that supports initial impressions
confirmation bias,
status quo bias
clinicians tend to stick with initial impressions as the number of new possible alternative diagnoses increases
the tendency to be affected by how information is framed or presented
framing effect
Interventions to reduce diagnostic errors
Cognitive awareness
System-based improvements
Take-Home Points
- Anchoring is the tendency to stick with initial impressions even as new information becomes available.
- Anchoring could be reduced if clinicians:
- Explicitly consider base rates (prior probabilities), sensitivity, and specificity of diagnostic tests and maneuvers when diagnosing common clinical conditions.
- Actively seek information that could refute the current provisional diagnosis.
- Frame their diagnostic thinking to avoid premature diagnostic labeling and share uncertainty.
- Use system-based interventions including structured diagnostic assessments, diagnostic decision support, or computerized expert diagnostic systems.
