Background:

  • Standing orders guide prehospital care.
  • On-line medical direction (OLMD) provides real-time physician oversight.

Purpose of the Study:

  • Determine the frequency of physician orders during OLMD.
  • Describe the nature of OLMD orders.
  • Measure OLMD time intervals.

Main Methods:

  • Blinded, prospective study conducted at a university hospital base-station.
  • Involved 10 emergency physicians and 50 advanced life support providers.
  • Independent observers recorded OLMD events and times.

Main Results:

  • Physician orders were issued in 19% (47/245) of cases, often for interventions covered by standing orders.
