The assessment of patient injury severity during a mass casualty incident (MCI) is best described as encompassing all relevant factors that contribute to understanding a patient's condition. This includes abnormal physiological signs, which may indicate the extent of shock or organ dysfunction; obvious anatomical injuries, which highlight visible traumatic wounds that can guide immediate treatment; and concurrent disease factors that can complicate the injury and influence treatment decisions.

In an MCI scenario, quick and accurate triage is crucial, as it helps prioritize patients based on the severity of their injuries and needs for care. By considering all these aspects—physiological status, visible trauma, and existing medical conditions—emergency responders can make more informed decisions about resource allocation, treatment priorities, and patient outcomes. The complexity and variability of injuries during such incidents necessitate a comprehensive approach to assessment, which is why integrating all these factors is essential in effective triaging and management of casualties.
