Insights

A new Child Abuse Clinical Decision Support (CA-CDS) system helps emergency departments identify infant physical abuse. This electronic tool provides evidence-based alerts to improve recognition and evaluation of suspected child abuse cases.

Area of Science:

  • Pediatric Emergency Medicine
  • Clinical Informatics
  • Child Abuse Recognition

Background:

  • Child physical abuse is frequently underdiagnosed, particularly in emergency settings.
  • Electronic clinical decision support (CDS) systems show promise in enhancing the detection of child abuse.

Purpose of the Study:

  • To develop and assess the usability of a natural language processing-based CDS system (CA-CDS) for identifying high-risk injuries suggestive of abuse in infant medical records.
  • To refine the CA-CDS system based on clinician feedback.

Main Methods:

  • A multidisciplinary team developed the CA-CDS prototype, incorporating user design principles and evidence-based recommendations.
  • Usability was evaluated through interviews with 24 clinicians across 4 emergency departments.
  • Interview data were analyzed using conventional content analysis to identify themes related to usability, barriers, and facilitators.

Main Results:

  • Clinicians identified benefits such as an "extra layer of protection" and evidence-based guidance.
  • User-centered design features included soft-stop alerts and integrated documentation.
  • Key recommendations for improvement involved content consolidation and clearer design; barriers included alert fatigue and documentation concerns.

Conclusions:

  • The CA-CDS system, with its user-centered design and evidence-based content, can assist healthcare providers in real-time recognition and evaluation of infant physical abuse.
  • The system has the potential to decrease the incidence of missed child abuse cases.
