Which healthcare personnel is responsible for calling the infectious disease physician during a mass casualty outbreak?

The medical command physician is the most appropriate choice for calling the infectious disease physician during a mass casualty outbreak. This role typically involves overseeing the medical response to emergencies and coordinating care among various healthcare personnel. In situations like a mass casualty incident, the medical command physician holds the responsibility of making critical decisions and managing resource allocation, which includes consulting with specialists such as infectious disease physicians. Their expertise is crucial in assessing situations involving potential outbreaks and implementing required protocols swiftly.

In contrast, the emergency room physician primarily focuses on immediate patient care and treatment within the emergency department, while the public health nurse may participate in community health response and education but would not typically engage in direct coordination with specialist physicians in the context of a mass casualty incident. The paramedic supervisor oversees the pre-hospital care provided by paramedics but does not have the authority to make such high-level calls regarding specialist consultations. Thus, the medical command physician plays a pivotal role in communication and management during a mass casualty scenario, making them the right choice for this responsibility.
