What does the acronym MIST stand for in the trauma history framework?

• A. Mechanisms, Injury, Symptoms, Treatment.
• B. Mechanisms, Injury, Symptoms, Time.
• C. Mechanisms, Injury, Signs, Treatment.
• D. Mechanisms, Incident, Symptoms, Treatment.

Answer: (A)

MIST is a brief trauma history mnemonic used to quickly organize critical information about a patient’s injury. Mechanisms refers to how the injury happened—the mechanism of injury (MOI)—which helps anticipate likely injuries. Injury covers the injuries that are present or suspected, guiding the focus of your exam. Symptoms are the patient’s subjective complaints—what they feel and report, such as pain or dizziness. Treatment includes any care already provided, like bleeding control or immobilization, so you know what has been done and what remains to be done. The phrasing Mechanisms, Injury, Symptoms, Treatment aligns with the way this framework is taught and used in practice, emphasizing the patient’s experience and the care already given. Other options change one element (for example, using Signs instead of Symptoms, or Time/Incident instead of Treatment), which alters the meaning and does not fit the standard MIST mnemonic.
