Emergency Medicine is a high-stakes field where decisions need to be taken under time-pressure in the setting of constant interruptions. Checklists are used in other high-stakes fields such as the flight industry, and are increasingly used in health care. This compendium provides: · Checklists for the initial management of critical patients suffering from syndromes such as anaphylaxis, hemorrhagic shock, sodium channel blocker poisoning · Checklists for the initial assessment of patients presenting with symptoms such as chest pain and weakness, provided alongside key clinical decision tools that help estimate the likelihoods of time-critical diagnoses or negative outcomes. The compendium's compact format makes it a useful bedside tool.
