Medical error and patient safety in the emergency department
Also known as Open disclosure · Adverse event and near miss · Root cause analysis · Just culture · Incident reporting · Sentinel event · Never event
Medical error and patient safety in the emergency department — the systems approach via Reason's Swiss cheese model with the distinction between active failures (sharp end) and latent failures (blunt end), the differential of event categories (near miss, no-harm incident, adverse event, sentinel event, never event, negligence), the open disclosure protocol and the statutory duty of candour, incident reporting (what, when and how), the steps of root cause analysis, the common ED errors (diagnostic — missed MI, SAH and AAA; medication — dosing and allergy; procedural), just culture and the Marx algorithm distinguishing human error from reckless conduct, and the second victim. ACEM-primary, globally tagged.

Meet the patient
A 72-year-old man with chest pain is prescribed morphine 1 mg intravenously. The resident draws up and gives morphine 10 mg — a ten-fold error — and within minutes the respiratory rate falls to 6 and the saturation to 88 per cent on room air. Naloxone 0.4 mg intravenously at the bedside reverses it, and the patient is stable on the monitor.[1]
The reversal is the easy part. The next forty-eight hours hold the real examination: treat the patient, preserve the ampoule, document factually, report within the shift, disclose openly, analyse the system, apply just culture, and support the clinician who made the error. Hold those eight duties and the whole topic arranges itself around them.[1]
