Insights
Bruising patterns and history significantly differ between confirmed physical abuse (PA) and excluded cases in young children. Understanding these differences aids in identifying child abuse more effectively.
Area of Science:
- Pediatrics
- Child Protection
- Forensic Medicine
Background:
- Suspected physical abuse (PA) in children presents diagnostic challenges.
- Bruising characteristics are key indicators in evaluating potential child abuse.
- Distinguishing between accidental and abusive injuries is crucial for child welfare.
Purpose of the Study:
- To characterize bruising and presentation in children referred for suspected PA.
- To compare bruising patterns between confirmed PA and excluded cases.
- To enhance the understanding of bruising associated with physical abuse.
Main Methods:
- Cross-sectional study of 519 children under 6 years old.
- Referred to two pediatric child protection teams.
- Analysis of bruise characteristics (number, location, appearance) and presenting history.
Main Results:
- Physical abuse (PA) was confirmed in 69% of referred children.
- Confirmed PA cases showed significantly more bruises and affected sites (p<0.001).
- Specific bruise locations (buttocks, genitalia, ears, cheeks, neck, trunk, thighs, upper arms) and patterns (petechiae, clusters, distinct patterns) were strongly associated with confirmed PA.
Conclusions:
- Presenting history and bruising patterns significantly differentiate confirmed PA from excluded cases.
- Findings offer deeper insights into bruising characteristics indicative of physical abuse.
- Improved understanding can aid in more accurate diagnosis and intervention for child abuse.
Objective:
To describe the characteristics of bruising and mode of presentation of children referred to the paediatric child protection team with suspected physical abuse (PA), and the extent to which these differ between the children where abuse was confirmed and those where it was excluded.
Design:
Cross-sectional study.
Setting And Patients:
519 children, <6 years, referred to two paediatric child protection teams.
Main Outcome Measures:
The mode of presentation, number, anatomical distribution, size and appearance of bruises according to whether PA was confirmed or excluded. ORs with 95% CI were calculated where relevant.
Results:
PA was confirmed in 69% of children; the rate varied from 84% when abuse was witnessed, admitted, alleged or where explanation for injury was absent or implausible, to 50% where there was a concerning history. Significantly more children with PA had bruises (89.4%) than PA-excluded (69.9%) and had significantly more sites affected (p<0.001). The odds of a PA child having bruising to: buttocks/genitalia (OR 10.9 (CI 2.6 to 46), left ear (OR 7.10 (CI 2.2 to 23.4), cheeks (Left (OR 5.20 (CI 2.5 to 10.7), Right OR 2.83 (CI 1.5 to 5.4)), neck (OR 3.77 (CI 1.3 to 10.9), trunk (back (OR 2.85 (CI 1.6 to 5.0) front (OR 4.74 (CI 2.2 to 10.2), front of thighs (OR2.48 (CI 1.4 to 4.5) or upper arms (OR 1.90 (CI 1.1 to 3.2) were significantly greater than in children with PA-excluded. Petechiae, linear or bruises with distinct pattern, bruises in clusters, additional injuries or a child known to social services for previous child abuse concerns were significantly more likely in PA.
Conclusions:
Features in the presenting history, the extent and pattern of bruising differed between children with confirmed PA and those where abuse was excluded. These findings can provide a deeper understanding of bruising sustained from PA.
