Li et al reported a clinical model for prediction of an initial violent injury due to interpersonal violence. This Initial Violent Injury Risk Prediction Tool (IVI-RPT) can help to identify an adolescent at risk for violence. The authors are from Denver Health Medical Center, University of Colorado and Rocky Mountain Regional Veterans Affairs Medical Center.
Patient selection: adolescent from 12 to 18 years old
Parameters:
(1) age of the patient
(2) history of physical fight in past year
