  • Misdiagnosis of neurologic emergencies can result in serious neurologic dysfunction or death.
  • A recent retrospective analysis using AHRQ databases looked at >3 million adults discharged from the ED with diagnoses of atraumatic headache or back pain.
  • A serious neurologic condition or death occurred within 30 days after ED discharge in:
    • 0.5% of patients with nonspecific diagnosis of headache
    • 0.2% of patients with nonspecific diagnosis of back pain
  • The frequency of adverse outcome was highest between days 1 and 3 after ED discharge.
  • The most frequent adverse outcome was ischemic stroke (18.1%) for headache and intraspinal abscess (44%) for back pain.
  • Age  85, male sex, non-Hispanic white, comorbidities such as neurologic disorders, HIV/AIDS, and malignancy were associated with higher incidence of adverse outcome.

Bottom Line: The rate of serious neurologic conditions missed at an initial ED visit is low.  However, the potential harm of misdiagnosis can be substantial.
