MATERIALS AND METHODS This retrospective study was compliant with HIPAA, and(More)
OBJECTIVES In the emergency department (ED), a significant amount of radiation exposure is due to computed tomography (CT) scans performed for the diagnosis of appendicitis.

STUDY OBJECTIVE We determine the minimum mortality reduction that helicopter emergency medical services (EMS) should provide relative to ground EMS for the scene transport of trauma victims to offset higher costs, inherent transport risks, and inevitable overtriage of patients with minor injury. METHODS We developed a decision-analytic model to compare(More)
