Direct communication for immediate medical direction is known as which form of medical control?

• A. On-line medical control
• B. Off-line medical control
• C. Pharmacognosy
• D. Prefilled syringes

Answer: (A)

Real-time, direct physician involvement during patient care is on-line medical control. This form relies on immediate communication—via radio, phone, or telemedicine—between the EMS provider at the scene and a physician or medical director to obtain authorization for treatments, dosing, and management as the patient’s condition evolves. Off-line medical control covers standing orders and protocols that allow care without real-time contact. Pharmacognosy is the study of drugs from natural sources, and prefilled syringes are a medication delivery format, not a control mechanism. So direct communication for immediate medical direction fits on-line medical control.
