Medically Unnecessary Venipuncture in Autism Spectrum Disorder Behavior Assessments | JoVE Visualize

Area of Science:

Pediatric Emergency Medicine

Clinical Pathology

Background:

Children with autism spectrum disorder (ASD) presenting to the emergency department (ED) with behavioral disturbances often undergo routine laboratory testing.
The clinical utility of these tests in asymptomatic or behaviorally disturbed children with ASD is not well-established.
Autism spectrum disorder affects communication and behavior, and medical evaluations in the ED can be challenging.

Purpose of the Study:

To evaluate the clinical value and impact of routine laboratory testing during behavioral disturbance assessments in pediatric patients with autism spectrum disorder (ASD).
To determine if abnormal laboratory findings in this population lead to significant medical interventions or diagnoses.
To inform best practices for laboratory utilization in the ED for children with ASD.

Main Methods:

Retrospective chart review of 209 pediatric patients (ages 3-21) with ASD presenting with behavioral disturbance across three pediatric EDs.
Analysis of screening laboratory tests performed, with abnormal results defined by local standards.
Assessment of the medical significance of abnormal findings, defined by the need for intervention, observation, or a non-behavioral diagnosis.

Main Results:

84% of patients underwent venipuncture for screening labs, with 97% showing abnormal results.
Only 1% of abnormal laboratory findings (2 out of 209 encounters) were clinically significant, requiring medical intervention.
Disparities observed in venipuncture rates and psychiatric admissions based on race.

Conclusions:

Routine laboratory screening in children with ASD presenting with behavioral disturbances frequently reveals abnormal results lacking clinical relevance.
Current practices may lead to unnecessary and potentially distressing venipuncture for children with ASD.
Clinical decision-making regarding laboratory testing in this vulnerable pediatric population requires careful consideration to minimize iatrogenic harm.
