Management of patients with suspected but unidentified poisoning in the emergency department: a joint Royal College of Emergency Medicine and National Poisons Information Service best practice guideline
When faced with an undiagnosed toxic exposure, adopt a systematic toxidromic approach focusing on the patient's evolving clinical picture rather than getting stuck waiting for a definitive toxin ID. Remember to continuously reassess the patient based on how potential toxins are metabolized and excreted; this is more critical than any single initial test result. Always cross-reference this general guidance with specific local poison control advice.
This new joint guideline from the Royal College of Emergency Medicine and the National Poisons Information Service provides a much-needed generalized framework for managing patients in the ED when poisoning is suspected but not yet confirmed. Recognizing that toxicology can be complex, the authors advocate strongly for adopting a toxidromic approach, meaning management should focus on the overall clinical picture and potential toxicological pathways rather than waiting for definitive identification. A key element stressed throughout is the need to constantly consider the toxicokinetics of any potential agent because the patient's status is inherently dynamic. While this guideline offers excellent scaffolding for initial assessment and guiding differential diagnosis, it explicitly cautions that it does not supersede specific protocols found in TOXBASE or local poison centers.
