James Scheulen is the chief administrative officer for emergency services and capacity management for Johns Hopkins Medicine and president of Johns Hopkins Emergency Medical Services. He is responsible for managing hospital capacity at The Johns Hopkins Hospital and the overall coordination and operations of the Baltimore and Washington, D.C., area Johns Hopkins Medicine Emergency Departments, which together manage nearly 300,000 patient visits each year. Scheulen is considered to be an expert in hospital and emergency department operations and is a leader in applying system engineering concepts to health care management.

Scheulen is the liaison between Johns Hopkins and the Maryland Institute for Emergency Medical Services, and has been appointed to the Maryland Statewide Emergency Medical Services Advisory Committee and the Governor’s Emergency Management Advisory Committee. He was also involved in the creation of the U.S. Government Accountability Office, American Hospital Association and Baltimore City Health Department reports on emergency department overcrowding; the Maryland Health Care Commission report on emergency department utilization; and the Maryland Institute for Emergency Medical Services Systems’ Yellow Alert Taskforce recommendations.

He is also the founding member of the Academy of Administrators in Academic Emergency Medicine and, since 2008, has been the founder and president of its Benchmark Survey Committee.

Scheulen is also the founder and director of the Hopkins Access Line and Johns Hopkins Lifeline Critical Care Transportation Program, managing the interhospital transportation of patients via ground and air. With the addition of the intrahospital transport teams, Lifeline is generally considered to be the largest hospital-based transportation program in the country. The Hopkins Access Line and the Central Physician Directory office manage communications with referring physicians and are models for the health care industry.

With the director of the Department of Emergency Medicine, Scheulen is responsible for the creation and ongoing operations of the Johns Hopkins Office of Critical Event Preparedness and Response (CEPAR), an office designed to assure a coordinated response to critical events across the entire Johns Hopkins enterprise. Besides providing for enterprise coordination, CEPAR is responsible for setting emergency response policy; integrating the Johns Hopkins system with local, state and federal plans; and providing operational coordination during events.

Scheulen is also a primary investigator for the Johns Hopkins National Center for the Study of Preparedness and Critical Event Response (PACER), a Homeland Security center of excellence dedicated to preparedness related research.

Scheulen has more than 25 peer reviewed publications on topics, including care of the burn patient, Emergency Department operations and crowding, disaster preparedness and response and, most recently, the use of simulation modeling in designing emergency departments and emergency department operations.
