Insights

Sociomedical evaluations for suspected abusive head trauma in Yokohama are inadequate. Many infant intracranial hemorrhage cases lacked thorough examinations and reporting to child protection services.

Area of Science:

  • Pediatrics
  • Forensic Medicine
  • Public Health

Background:

  • No prior studies assessed combined evaluations for abusive head trauma in Japan.
  • Focus on Yokohama's local districts for child protection adequacy.

Purpose of the Study:

  • Evaluate the adequacy of combined assessments for abusive head trauma.
  • Examine reporting practices to child protection services.

Main Methods:

  • Questionnaire survey of hospitalized patients under 24 months with intracranial hemorrhage (ICH).
  • Data collected from 11 large hospitals in Yokohama, Japan (2011-2013).

Main Results:

  • 51 ICH patients identified; 84% under 12 months.
  • Subdural hematoma was the most common diagnosis (51%).
  • Significant gaps in examinations (skin lesions, skeletal surveys, funduscopy) and reporting to child protection teams and services.

Conclusions:

  • Sociomedical evaluation of suspected child abuse is systematically inadequate in Yokohama.
  • Urgent need for improved inter-agency collaboration and standardized protocols.
