Predictive value of historical and physical characteristics for the diagnosis of child abuse.

Child abuse by burning may be difficult to recognize, especially since the injuries are often small. Historical and physical findings that can be elicited in the initial examination can be helpful in initiating a more in-depth investigation. An injury inconsistent with the history given or a delay in seeking medical treatment were the two most frequent reports that elicited suspicion. As isolated findings, however, they had a low predictive value. The presence of two or more of 13 factors increased the yield in child abuse identification to more than 60%.
