Evaluating bias of child maltreatment referrals in encounters for unintentional ingestions

Unintentional ingestions commonly result in presentation to the pediatric emergency department (PED). No standardized recommendations exist regarding when to call Child Protective Services (CPS) for unintentional ingestions, which allows for the possibility of biased decision-making. Identify patient and visit level characteristics associated with CPS referral status in unintentional ingestion encounters. Retrospective cross-sectional study of children ≤6 years old presenting with unintentional ingestion to a metropolitan PED from 2015 to 2021. ICD-10-CM codes were used to identify unintentional ingestion visits in the electronic health record. CPS referral was determined by manual chart review. Bivariable and multivariable logistic regression models identified patient and visit level characteristics associated with CPS referral. Socioeconomic status (SES) was classified based on zip code, the Child Opportunity Index data, and insurance. Of 3,836 charts reviewed, 808 met inclusion criteria. CPS referrals were made in 109 (13.5%) visits. Compared to non-Hispanic white patients, non-Hispanic Black patients had 7.37 (95% CI:1.38, 39.26) higher adjusted odds of being referred to CPS after adjusting for triage level, age, and ingestion type. Patients in the Lowest SES group had a 3.01 (95% CI:1.42, 6.40) higher adjusted odds when compared to the Middle/Highest SES group. This study found that CPS referrals in unintentional ingestions occur more often in those identifying as non-Hispanic Black and in those in the Lowest SES group, suggesting clinician bias may impact the decision regarding referrals. To mitigate subjective decision-making, we propose creating standardized, objective CPS referral criteria for unintentional ingestions. • Socioeconomic and racial CPS referral bias in pediatric unintentional ingestions. • Need for standardized CPS referral criteria in pediatric unintentional ingestions. • Demographic and patient characteristics of pediatric unintentional ingestions.
