The Interplay of Outpatient Services and Psychiatric Hospitalization Among Medicaid-enrolled Children with Autism Spectrum Disorders
Overview
Affiliations
Objective: To examine whether increased provision of community-based services is associated with decreased psychiatric hospitalizations among children with autism spectrum disorders (ASDs).
Design: Retrospective cohort study using discrete-time logistic regression to examine the association of service use in the preceding 60 days with the risk of hospitalization.
Setting: The Medicaid-reimbursed health care system in the continental United States.
Participants: Medicaid-enrolled children with an ASD diagnosis in 2004 (N = 28 428).
Main Exposures: Use of respite care and therapeutic services, based on procedure codes.
Main Outcome Measures: Hospitalizations associated with a diagnosis of ASD (International Classification of Diseases, 10th Revision, codes 299.0, 299.8, and 299.9).
Results: Each $1000 increase in spending on respite care during the preceding 60 days resulted in an 8% decrease in the odds of hospitalization in adjusted analysis. Use of therapeutic services was not associated with reduced risk of hospitalization.
Conclusions: Respite care is not universally available through Medicaid. It may represent a critical type of service for supporting families in addressing challenging child behaviors. States should increase the availability of respite care for Medicaid-enrolled children with ASDs. The lack of association between therapeutic services and hospitalization raises concerns regarding the effectiveness of these services.
