Survey Items:
Denominator: CSHCN age 0-17 years
Numerator: Functional limitation (alone or with any other qualifying need); Prescription medication ONLY; Services needs ONLY; Prescription medication AND service needs
Revisions and Changes: No changes, same as 2003.
Additional Notes: This variable stratifies CSHCN according to four mutually exclusive categories, each representing specific combinations of CSHCN Screener health consequences. This measure is based on the CSHCN Screener, developed by the Child and Adolescent Health Measurement Initiative (CAHMI). The four CSHCN types are defined as follows: Rx meds only - CSHCN identified by current need for or use of prescription medication to manage an ongoing medical, behavioral, or other chronic health condition, and who qualified on no other CSHCN Screener criterion; Service use only - CSHCN who did not qualify on Rx medications or functional limitation but did qualify on one or more of three service-related screener criteria: elevated need or use of medical, mental health or educational services; need or use of specialized therapies; need for treatment or counseling for chronic emotional, behavioral, or developmental condition Rx meds AND service use - CSHCN who did not qualify on functional limitation, but did qualify based on both prescription medication use AND elevated service use (described above) Functional limitation - CSHCN qualifying on functional limitation criteria (limited ability to do things most other children the same age can do, due to the presence of an on-going medical, behavioral or other health condition) alone or in combination with any other screening criteria A detailed analysis of CSCHN subtypes has been published: Bramlett, M.D., Read, D., Bethell, C. and Blumberg, S.J. Differentiating subgroups of children with special health care needs by health status and complexity of health care needs. Maternal and Child Health Journal. 2009; 13:151-163.
Treatment of Unknown Values: Unknown values (responses coded as 'refused', 'don't know', or system missing) are not included in the denominator when calculating prevalence estimates and weighted population counts displayed in the data query results table. In nearly every case, the proportion of unknown values is less than 1% and the exclusion of these values does not change the prevalence estimates (%) and only marginally affects the weighted population counts (Weighted Est.). Exceptions are noted in the form of a “Data Alert” at the bottom of a results table.
History and Development: The Maternal and Child Health Bureau leads the development of the NSCH survey and indicators, in collaboration with the National Center for Health Statistics (NCHS) and a national technical expert panel. The expert panel includes representatives from other federal agencies, state Title V leaders, family organizations, and child health researchers. Previously validated questions and scales are used when available. Respondents’ cognitive understanding of the survey questions is assessed during the pretest phase and revisions made as required. All final data components are verified by NCHS and DRC/CAHMI staff prior to public release.
C.I. = 95% Confidence Interval. Percentages and population estimates (Pop.Est.) are weighted to represent child population in US.
