- How various types of bias can lead to diagnostic errors
- To avoid these biases
- Re-assess DDx as new data becomes available
- Do not ignore or discount data that contradicts your DDx
- Do not blindly accept a diagnosis from another provider without assessing the patient yourself
- Re-assess DDx if therapeutic plan is not improving patient's clinical condition
- Re-assess patient and revist the H&P
- Sticking too heavily to first piece of data or initial impression
- Ignoring or discounting data that contradicts initial impression and focusing only on data that supports initial impression
- Finding a diagnosis that fits the clinical situation and then suspending further consideration of a broader DDx
- "This patient had a known history of GERD so their abdominal pain fits a diagnosis of a gastric ulcer"
- Diagnosis presented by one physician is accepted by the next without reassessing the DDx
- "Mr. Smith's family doctor sent him in to the ED to be treated for pneumonia"
- What if his cough and SOB are due to CHF, ACS, or Dsxn?
- "The paramedics said this guy is a drunk who was passed out at the train station"
- What if he wasn't passed out or drunk but seized or syncopized or had a CNS injury?
