Who is responsible for answering OLMC calls at Region 11 EMS Resource or Associate Hospitals?

• A. Trained ECRNs or ECPs
• B. Paramedic field supervisors
• C. Police liaison officers
• D. Administrative staff

Answer: (B)

On-line medical control is the live physician direction used to guide patient care in the field. In Region 11 EMS Resource or Associate Hospitals, the person designated to answer OLMC calls is the paramedic field supervisor. These supervisors are the on-scene leaders who have the authority and training to handle direct contact with medical control, relay the physician’s orders, ensure they’re understood and applied on the patient, and communicate updates back to the hospital or Medical Direction as needed. Having a field supervisor as the OLMC contact streamlines decisions at the scene, reduces delays, and provides a clear line of accountability for what the crew does next.

Additional clinicians like ECRNs or ECPs are important members of the broader clinical team, but they are not the designated on-line medical control responders for OLMC calls in this system. Police liaison officers focus on safety and security rather than medical direction, and administrative staff handle non-clinical tasks rather than provide real-time medical orders in the field.
