Insights

The Massachusetts All-Payer Claims Database can identify children with chronic tic disorders. This study found it feasible for tracking pediatric tic disorder incidence.

Area of Science:

  • Pediatric Neurology
  • Public Health Surveillance
  • Health Informatics

Background:

  • Chronic tic disorders affect nearly 1.5 million US children, often with co-occurring neuropsychiatric conditions.
  • These complex childhood-onset conditions involve involuntary movements or sounds and are under-recognized.
  • Comorbidity with neuropsychiatric illness is common in pediatric chronic tic disorders.

Purpose of the Study:

  • To assess the feasibility of using the Massachusetts All-Payer Claims Database (MA-APCD) for identifying new cases of chronic tic disorders.
  • To determine if claims data can effectively capture the incidence of pediatric tic disorders.
  • To establish a foundation for future research on care access and quality for chronic tic disorders.

Main Methods:

  • Retrospective analysis of the 2012-2016 MA-APCD.
  • Inclusion criteria: pediatric participants (4-18 years) with continuous insurance (2013-2016).
  • Incident tic disorder diagnosis defined as the first ICD-9/ICD-10 code for tic disorders within the study period, with no prior diagnosis.

Main Results:

  • Over 1.6 million claims were analyzed; 1,258 claims indicated an incident tic disorder diagnosis.
  • The average age at diagnosis was 9.7 years (±3.5).
  • The pediatric population diagnosed with tic disorders was predominantly male (74.5%) and covered by Medicaid (64.8%).

Conclusions:

  • The MA-APCD is a feasible resource for studying the incidence of chronic tic disorders in children.
  • This methodology supports future investigations into healthcare access and quality for pediatric tic disorder patients.
  • The findings highlight the utility of large-scale claims databases for epidemiological research in child neurology.
