Taking to the Sky: Launching an EM Resident Flight Physician Program
Resident involvement in air medical transport leads to significant mutual benefit for residents, residency programs, and flight programs. Residents gain unique clinical experiences and broaden their understanding of AMT and diversity of care settings. Residency programs benefit from the experiences of their residents. Flight programs gain enthusiastic and knowledgeable groups of new physicians who can augment the organization’s educational and clinical capabilities. Starting a resident flight program requires careful planning and significant coordination of stakeholders, but the result is an outstanding clinical experience for clinicians and patients alike.
