TOPIC: Artificial Intelligence-Assisted Identification of Child Abuse and Neglect in Hospital Settings with Implications for Bias Reduction and Future Interventions

Child abuse and neglect are defined as any action (physical, emotional, and/or sexual) by a caregiver that results in harm to a child. Around 700,000 children are abused yearly in the US. There is a lack of knowledge about factors that can be used to phenotype child abuse and neglect using electronic health records (EHR). In clinical practice, even experienced professionals miss clinical presentations of abuse and neglect. Clinician bias begets the over-suspicion of neglect and abuse directed at Black and Latinx communities. In 2018, approximately 50% of the children with confirmed abuse and neglect cases were Black and Latinx in the US.

This presentation will discuss considerations for generating a phenotype of child abuse and neglect in emergency departments using secondary data from EHR. Implications will be provided for racial bias reduction and development of further decision support tools to assist in identification of abuse and neglect.   


Dr. Aviv Y. Landau is the Associate Director of SAFElab and a postdoctoral research scientist at Columbia University's Data Science Institute under the guidance of Prof. Desmond Patton. In his research, he uses qualitative, network, and computational data methodologies to explore how youth engage on social media when experiencing and coping with social rejection, cyberbullying, and child abuse and neglect. 

Dr. Landau worked for several years as a social worker in Israel with youth from diverse and marginalized backgrounds such as; immigrants, LGBQs, and school dropouts. Dr. Landau received his B.S.W, M.S.W, and Ph.D. from the University of Haifa, Israel.
