Preventing elopement in children with autism spectrum disorder.

Reports of missing children with autism spectrum disorder (ASD) are common in the media, and elopement can lead to dire consequences. This study quantified the use of preventive measures that target elopement, plus identified child/family characteristics associated with elopement and the use of preventive measures. This cross-sectional study included 394 caregivers of children ages 2-17 years with ASD followed in an academic medical center's Developmental-Behavioral Pediatrics clinic. Details about elopement, preventive measure use, and sociodemographic characteristics were assessed via an investigator-designed, parent advocate-approved questionnaire, while pertinent clinical factors were extracted from patients' electronic health records. Two hundred and sixty-seven caregivers (68%) reported elopement by their child. Elopement risk was not associated with sociodemographic characteristics, nor with any specific comorbidity or neurobehavioral medication. Children with limited communication skills were more likely to have a history of elopement (OR 2.24, 95% CI 1.30-3.84; P = 0.004). The most common preventive measure used was lock(s) at top of doors (51%), while less than a quarter of families were using handicap permits, signs/visual markers, or tracking devices. Implementation of certain modifications was statistically associated with socioeconomic status and comorbidities of interest. In addition to supporting previous literature about the increased elopement risk in children with limited communication skills, this study is the first to reveal that caregiver use of numerous preventive measures varies widely. The associations noted with use of specific preventive measures can help guide recommendations for this dangerous comorbid symptom, and provide information needed for future studies to assess the efficacy of various preventive measures.

LAY SUMMARY: Elopement, defined as leaving an area without permission and placing oneself in a potentially dangerous situation, is a behavior exhibited by many children with autism. There is little information about the use of various modifications that target elopement in the pediatric population. This study identifies child/family characteristics that were related to elopement and the use of modifications, and stresses the importance of counseling families of children with autism about elopement.
