title: Association of perpetrator relationship to abusive head trauma clinical outcomes.
abstract: The diagnosis of abusive head trauma (AHT) remains a significant public health problem with limited prevention success. Providing protection from further harm is often challenged by the difficulty in identifying the alleged perpetrator (AP) responsible for this pediatric trauma. The objective of this study was to evaluate demographic and clinical characteristics of children with AHT and the relationship between APs and their victims in a large, multi-site sample. Understanding the AHT risks from various caregivers may help to inform current prevention strategies. A retrospective review of all cases of AHT diagnosed by child protection teams (CPT) from 1/1/04 to 6/30/09 at four children's hospitals was conducted. Clinical characteristics of children with AHT injured by non-parental perpetrators (NPP) were compared to parental perpetrators (PP). There were 459 children with AHT; 313 (68%) had an identified AP. The majority of the 313 children were <1 year of age (76%), Caucasian (63%), male (58%), receiving public assistance (80%), and presented without a history of trauma (62%); mortality was 19%. Overall, APs were: father (53%), parent partner (22%), mother (8%), babysitter (8%), other adult caregiver (5%); NPP accounted for 39% of APs. NPPs were more likely to cause AHT in children ≥ 1 year (77% vs. 23%, p<0.001) compared to PP. Independent associations to NPP included: older child, absence of a history of trauma, retinal hemorrhages, and male perpetrator gender. While fathers were the most common AP in AHT victims, there is a significant association for increased risk of AHT by NPPs in the older child, who presents with retinal hemorrhages, in the hands of a male AP. Further enhancement of current prevention strategies to address AHT risks of non-parental adults who provide care to children, especially in the post-infancy age seems warranted.
