Benefit-cost analysis and autism services: a response to Jacobson and Mulick

The Economic Costs of Autism Spectrum Disorder: A Literature Review

Autism is associated with a range of costs. This paper reviews the literature on estimating the economic costs of autism spectrum disorder (ASD). More or less 50 papers covering multiple countries (US, UK, Australia, Canada, Sweden, the Netherlands, etc.) were analysed. Six types of costs are discussed in depth: (i) medical and healthcare service costs, (ii) therapeutic costs, (iii) (special) education costs, (iv) costs of production loss for adults with ASD, (v) costs of informal care and lost productivity for family/caregivers, and (vi) costs of accommodation, respite care, and out-of-pocket expenses. A general finding is that individuals with ASD and families with children with ASD have higher costs. Education costs appear to be a major cost component for parents with children with ASD.

Cost Offset Associated With Early Start Denver Model for Children With Autism

OBJECTIVE

To determine the effect of the Early Start Denver Model (ESDM) for treatment of young children with autism on health care service use and costs.

METHOD

We used data from a randomized trial that tested the efficacy of the ESDM, which is based on developmental and applied behavioral analytic principles and delivered by trained therapists and parents, for 2 years. Parents were interviewed about their children's service use every 6 months from the onset of the intervention to follow-up (age 6 years). The sample for this study consisted of 39 children with autism who participated in the original randomized trial at age 18 to 30 months, and were also assessed at age 6 years. Of this sample, 21 children were in the ESDM group, and 18 children were in the community care (COM) group. Reported services were categorized and costed by applying unit hourly costs. Annualized service use and costs during the intervention and post intervention for the two study arms were compared.

RESULTS

During the intervention, children who received the ESDM had average annualized total health-related costs that were higher by about $14,000 than those of children who received community-based treatment. The higher cost of ESDM was partially offset during the intervention period because children in the ESDM group used less applied behavior analysis (ABA)/early intensive behavioral intervention (EIBI) and speech therapy services than children in the comparison group. In the postintervention period, compared with children who had earlier received treatment as usual in community settings, children in the ESDM group used less ABA/EIBI, occupational/physical therapy, and speech therapy services, resulting in significant cost savings in the amount of about $19,000 per year per child.

CONCLUSION

Costs associated with ESDM treatment were fully offset within a few years after the intervention because of reductions in other service use and associated costs.

Services for Children With Autism Spectrum Disorders

Recommendations for improving school and community-based services for children with autism spectrum disorders (ASD) in the state of Virginia were investigated. Participants consisted of 783 parents of children birth to age 22 with a medical diagnosis of ASD. Data obtained through an open-ended survey question were analyzed both quantitatively and qualitatively. Parents recommended improving the quality, quantity, accessibility, and availability of services; educating and training individuals to work effectively with children with ASD; increasing funding for services; and creating appropriate school placements and educational programs. The findings from this study suggest the need for increased individualization of and accessibility to services. Future state-level research must examine the variables that affect parent recommendations and evaluate the quality of existing services for children with ASD.

Medicaid expenditures for children with autistic spectrum disorders: 1994 to 1999

This study used data from 1994 to 1999 from one large county in Pennsylvania to estimate the Medicaid expenditures of children diagnosed with autism spectrum disorders (ASD) and to compare these expenditures with those of other Medicaid-eligible children. On average, children diagnosed with ASD had expenditures 10 times those of other children. Differences in expenditures were driven in large part by inpatient psychiatric care. Further research is required to determine whether hospitalized children could be served in less restrictive and less expensive settings. Lack of differences in ambulatory care expenditures suggests that children with ASD are not receiving additional primary care services that would be indicative of appropriately coordinated services as suggested by the medical home model.

Annotation: Economic evaluations of child and adolescent mental health interventions: a systematic review

BACKGROUND

Recognition has grown over recent years of the need for economic information on the impacts of child and adolescent mental health problems and the cost-effectiveness of interventions.

METHODS

A range of electronic databases were examined using a predefined search strategy to identify economic studies which focused on services, pharmacological interventions and other treatments for children and adolescents with a diagnosed mental health problem or identified as at risk of mental illness. Published studies were included in the review if they assessed both costs and outcomes, with cost-effectiveness being the primary interest. Studies meeting the criteria for inclusion were assessed for quality.

RESULTS

There are still relatively few economic evaluations in this field. Behavioural disorders have been given relatively greater attention in economic evaluations of child and adolescent mental health. These studies tentatively suggest child behavioural gains and parent satisfaction from parent and child training programmes, although the cost-effectiveness of the location of delivery for behavioural therapies is less clear. In general, the quality of economic evaluations was limited by small sample sizes, constrained measurement of costs, narrow perspectives and over-simple statistical and econometric methods.

CONCLUSION

Economic evaluations in the field of child and adolescent mental health interventions are few in number and generally poor in quality, although the number of studies being undertaken now appears to be rising.

Measuring the parental, service and cost impacts of children with autistic spectrum disorder: a pilot study

The aim of this study was to carry out a preliminary examination of a research instrument developed specifically to collect cost information for individuals with autistic spectrum disorder. There is very little cost information on children or adults with autism or autism-related disorder, and no study appears to have carried out a specific cost collection in this area. Although some global cost estimates can be made, little is known about the cost implications of parental burden. By using different techniques to collect indirect costs, the study outlines a functional methodology. Results from this small pilot study point to considerable economic burden for parents and give some indication of the associated costs of autistic spectrum disorder.
