Cost and Utilization with Enrollment in a Medical Home for Individuals with an Autism Spectrum Disorder and/or Intellectual Disability.

Individuals with intellectual and/or developmental disabilities (IDD) tend to incur high health care costs. The Neurobehavior HOME Program (HOME) is an interdisciplinary program that cares for this population. This study will evaluate the health care costs and utilization of individuals during their first year of enrollment in HOME and identify factors associated with higher cost and utilization. Secondary analysis of claims data were used to identify cost and utilization. Generalized linear regression and negative binomial regression were used to calculate utilization and cost. The mean total cost of care during the initial year of enrollment (n=239) per individual was $11,095.87, with $4,640.83 attributed to inpatient care. Those with diabetes (p=0.01), epilepsy (p=0.02), or mood disorders (p=0.03) were more likely to be admitted to the hospital and utilize the emergency department. These findings will enable systems and payers to better construct health care delivery reforms for this high-need population.
