Discuss a Case Meet Our Experts
Board-certified physicians | Emergency medicine and toxicology | Nationwide consultation
Expertise matched to the medical question
Emergency Medicine
Review of emergency evaluation, diagnosis, treatment, reassessment, monitoring, and disposition. Assignments are screened for fit with the selected physician’s clinical experience and the questions at issue.
Medical Toxicology
Consultation involving overdose, poisoning, medication toxicity, drug interactions, alcohol, drug testing, and the relationship between an exposure and an outcome.
When the specialties overlap
Some matters require analysis of both the effects of a drug or exposure and the emergency care provided. Our physicians’ training in both specialties supports a coordinated review of those questions.
