Research Type: 
Concussion Literature

Summary: In a cross-sectional study of outpatient visits for minor head injuries from the National Ambulatory Medical Care Survey (NAMCS) and the National Hospital Ambulatory Medical Care Survey (NHAMCS), outpatient visits for minor head injury between 2005 and 2009 were compared to visits in the emergency department (ED) for the same diagnoses using simple survey weighted descriptive statistics. For the five-year study period, there were 4,146,777 outpatient visits (includes office-based and hospital-based practices), and 6,077,147 ED visits, for minor head injury. In the outpatient setting, 14% of office-based visits and 21% of hospital-based visits referred patients for advanced imaging, while 63% of minor head injury patients evaluated in an ED underwent imaging. A return visit was arranged for 54% of minor head injury patients in office-based practices and 29% of patients in hospital-based clinics, while 67% of minor head injury patients were given instructions to follow-up after an ED visit.
