1 At least 1 documented physician's office visit for injury within 1 year prior to interview, based on the administrative data. Adolescents with emergency department or inpatient visits but no physicians' office visits for injury are excluded from the denominator.

2 Any documented emergency department or inpatient visits for injury within 1 year prior to interview, based on the administrative data. Adolescents with physicians' office visits but no emergency department or inpatient visits for injury are excluded from the denominator.

3 Analysis includes only those adolescents (N = 550) with administratively-defined injury
