Confidential Screening for Sex Trafficking Among Minors in a Pediatric Emergency Department

Child sex trafficking is a global health problem, with a prevalence of 4% to 11% among high-risk adolescents. The objective of this study was to confidentially administer a validated screening tool in a pediatric emergency department by using an electronic tablet to identify minors at risk for sex trafficking. Our hypothesis was that this modality of administration would adequately identify high-risk patients.

English- and Spanish-speaking patients from the ages of 12 to 17 years presenting to a large urban pediatric emergency department with high-risk chief complaints were enrolled in a prospective cohort over 13 months. Subjects completed a previously validated 6-item screening tool on an electronic tablet. The screening tool's sensitivity, specificity, and positive and negative predictive values were calculated. Multivariable logistic regression was performed to identify additional risk factors.

A total of 212 subjects were enrolled (72.6% female; median age: 15 years; interquartile range 13-16), of which 26 patients were subjected to child sex trafficking (prevalence: 12.3%). The sensitivity and specificity of the electronic screening tool were 84.6% (95% confidence interval [CI] 70.8%-98.5%) and 53.2% (95% CI 46.1%-60.4%), respectively. The positive predictive value and negative predictive value were 20.2% (95% CI 12.7%-27.7%) and 96.1% (95% CI 92.4%-99.9%), respectively. A previous suicide attempt and history of child abuse increased the odds of trafficking independent of those who screened positive but did not improve sensitivity of the tool.

A confidentially administered, previously validated, electronic screening tool was used to accurately identify sex trafficking among minors, suggesting that this modality of screening may be useful in busy clinical environments.
