Which component is not included in the MARCH primary assessment?

The MARCH primary assessment is designed to prioritize life-threatening conditions in a systematic manner, particularly in trauma situations. The components of MARCH stand for Massive Hemorrhage, Airway, Respirations, and Circulation, which reflects the critical steps that need to be taken in assessing and addressing immediate needs of a patient.

The component referred to as the medical history assessment is not included in the MARCH framework because it is secondary to immediate life-saving interventions. The primary assessment focuses on quickly identifying and addressing threats to life, rather than gathering a patient's medical history, which is more relevant during secondary assessments or less urgent situations. The goal of MARCH is to stabilize the patient and ensure that the most dangerous issues are managed promptly, thus making a medical history assessment more of a supporting action rather than a primary need in emergency care scenarios.
