Evaluating AI Symptom Checkers Before Patient-Facing Deployment
Patient-facing symptom checkers are high-stakes deployments — too cautious and they create unnecessary ED visits, too permissive and they miss emergencies. Evaluation requires clinical scenarios, not just accuracy metrics.

The premise
Symptom checker safety lives at the extremes; evaluation must include emergency detection, not just average accuracy.
What AI does well here
Build evaluation scenarios spanning routine, urgent, and emergency presentations
Stress-test with edge cases (atypical presentations of common emergencies — silent MI, atypical PE, ectopic pregnancy)
Compare AI triage decisions to clinician triage on the same scenarios
Evaluate language and reading-level access for the actual patient population
What AI cannot do
Substitute for clinical judgment in real patient encounters
Catch every emergency presentation (false negatives are inevitable)
Replace clear in-app guidance to call 911 for life-threatening symptoms
