Survey Items: K4Q20R, K4Q21R
Denominator: CSHCN age 0 -17 years
Numerator: CSHCN who had at least 1 preventive medical visit and at least 1 preventive dental visit in the past 12 months; CSHCN who did not achieve this outcome
Revisions and Changes: The items used to construct this measure were substantially altered from the way the measure was constructed in the 2005/06 NS-CSHCN. Items K4Q20R and K4Q21R measuring the number of preventive medical and dental visits (respectively) were used. These items align with the measurement of similar services in the 2007 National Survey of Children's Health.
Additional Notes: This measure is created by taking those responses of 1 or more visits on each of the preventive items. If either preventive medical or dental care were used zero times in the past 12 months, then this indicator is not successfully met. Children under 1 year old were excluded from needing preventive dental care. Therefore, any child under 12 months of age only needed to respond with 1 or more preventive medical visit to meet this indicator. Respondents with answers of don't know or refused to either item were set to missing.
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 NS-CSHCN survey, indicators and performance measures, 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.
