ABSTRACT To examine the relationship of availability and quality of a usual source of care (USC) to medical expenditures overall and for various types of health care services for children with special health care needs (CSHCN), as a group and by four diagnostic subgroups (asthma, non-asthmatic physical conditions, mental retardation, other mental illnesses).
Generalized linear models were used to estimate the annual average per capita medical expenditures (APCME) based on data from 820 CSHCN in the 1995 National Health Interview Survey on Disability and 1996 Medical Expenditure Panel Survey.
In 1996, 92% of non-institutionalized CSHCN in the United States had a USC. Of these, 52% were classified as receiving accessible care, 95% received comprehensive care, and 69% received satisfactory care. Approximately 89% of CSHCN had expenditures on health care in 1996 and the APCME was $1,344 for CSHCN as a group. Having a USC was associated with higher expenditures overall and for almost all types of health care services for CSHCN across conditions. Receiving comprehensive care was associated with lower total medical expenditures for CSHCN with asthma, whereas receiving satisfactory care was associated with higher total medical expenditures for CSHCN with non-asthma physical conditions.
Having a regular care provider is associated with higher expenditures for CSHCN across diagnosis. Among CSHCN with a USC, quality of care is associated with medical expenditures, although specific associations vary by the quality characteristic and the condition of the child. These results may mask heterogeneity in severity of condition and quality of care over time.

A study of average per capita medical expenses for ''usual care'' in children with special healthcare needs noted that expenses for children with MR when compared to special needs children without MR were substantially higher with respect to physician care, prescribed medication, emergency care, and hospitalization (Liu et al., 2008a). According to a recent report, the total public spending on intellectual disability in the United States was estimated to be $82.57 "

    ABSTRACT: The diagnosis, evaluation, and management of infantile spasms (IS) continue to pose significant challenges to the treating physician. Although an evidence-based practice guideline with full literature review was published in 2004, diversity in IS evaluation and treatment remains and highlights the need for further consensus to optimize outcomes in IS. For this purpose, a working group committed to the diagnosis, treatment, and establishment of a continuum of care for patients with IS and their families—the Infantile Spasms Working Group (ISWG)—was convened. The ISWG participated in a workshop for which the key objectives were to review the state of our understanding of IS, assess the scientific evidence regarding efficacy of currently available therapeutic options, and arrive at a consensus on protocols for diagnostic workup and management of IS that can serve as a guide to help specialists and general pediatricians optimally manage infants with IS. The overall goal of the workshop was to improve IS outcomes by assisting treating physicians with early recognition and diagnosis of IS, initiation of short duration therapy with a first-line treatment, timely electroencephalography (EEG) evaluation of treatment to evaluate effectiveness, and, if indicated, prompt treatment modification. Differences of opinion among ISWG members occurred in areas where data were lacking; however, this article represents a consensus of the U.S. approach to the diagnostic evaluation and treatment of IS.

    ABSTRACT: To test associations between having a medical home and health services use and expenditures among US children with special health care needs (CSHCN). Cross-sectional analysis. The 2003-2008 Medical Expenditure Panel Surveys. A total of 9816 CSHCN up to 17 years, including 1056 with a functional or sensory limitation and 8760 without a limitation. Parent or caregiver report of CSHCN having a medical home. We examined CSHCN's annual use of outpatient, inpatient, emergency department, and dental visits, and annual outpatient, inpatient, emergency department, prescription medication, dental, and other health care expenditures. CSHCN with a medical home had 14% more dental visits compared with CSHCN without a medical home (incidence rate ratio [IRR], 1.14; 95% CI, 1.03-1.25); this finding is significant for CSHCN without limitations but not for those with limitations. The medical home was associated with greater odds of incurring total, outpatient, prescription medication, and dental expenditures (odds ratio range, 1.25-1.92). Among CSHCN with a limitation, children with a medical home had lower annual inpatient expenditures compared with those without a medical home (mean, -$968; 95% CI, -$121 to -$1928), and among CSHCN without a limitation, children with a medical home had higher annual prescription medication expenditures compared with those without a medical home (mean, $87; 95% CI, $22-$153). There were few differences in annual health services use and expenditures between CSHCN with and without a medical home. However, the medical home may be associated with lower inpatient expenditures and higher prescription medication expenditures within subgroups of CSHCN.

    ABSTRACT: Background and objectives: Children with special health care needs (CSHCN) face unique challenges in accessing affordable health care. Massachusetts implemented major health reform in 2006; little is known about the impact of this state's health reform on uninsurance, access to care, and financial protection for privately and publicly insured CSHCN. Methods: We used a difference-in-differences (DD) approach to compare uninsurance, access to primary and specialty care, and financial protection in Massachusetts versus other states and Washington, DC before and after Massachusetts health reform. Parent-reported data were used from the 2005-2006 and 2009-2010 National Survey of Children with Special Health Care Needs and adjusted for age, gender, race/ethnicity, non-English language at home, and functional difficulties. Results: Postreform, living in Massachusetts was not associated with significant decreases in uninsurance or increases in access to primary care for CSHCN. For privately insured CSHCN, Massachusetts was associated with increased access to specialists (DD = 6.0%; P ≤ .001) postreform. For publicly insured CSHCN, however, there was a significant decrease in access to prescription medications (DD = -7.2%; P = .003) postreform. Living in Massachusetts postreform was not associated with significant changes in financial protection compared with privately or publicly insured CSHCN in other states. Conclusions: Massachusetts health reform likely improved access to specialists for privately insured CSHCN but did not decrease instances of uninsurance, increase access to primary care, or improve financial protection for CSHCN in general. Comparable provisions within the Affordable Care Act may produce similarly modest outcomes for CSHCN.
