Wisconsin sponsored a general oversample to enable CYSHCN subgroup analyses and more than doubled their 2020 and 2021 sample size with over 800 CYSHCN respondents. Oversampling provided more precise estimates of Title V National Performance Measures (NPMs), particularly for CYSHCN, and helped to reveal a statistically significant improvement in the percent of CYSHCN who have received services to prepare for the transition to adult health care (NPM-12) compared to the 2016 baseline (34.6% in 2020-2021 versus 21.1% in 2016). Without oversampling, this estimate would have been considered unreliable with wide confidence intervals and would not have been significantly different. Wisconsin is developing a CYSHCN surveillance report, the first of its kind to describe their CYSHCN population in terms of health status, access to care, and disparities.
Oregon sponsored a targeted oversample to enable reporting for all racial/ethnic groups. Prior to oversampling, child health estimates were only reportable (sample size of 30+) for non-Hispanic White, Hispanic, and non-Hispanic Asian populations. After oversampling, estimates are now reportable for all racial/ethnic groups (a first for non-Hispanic Black, American Indian/Alaska Native, and Native Hawaiian/Other Pacific Islander populations) and sufficient to support subgroup analyses for Hispanic and non-Hispanic Asian populations. Their large oversample also quintupled the size of their CYSHCN sample (~1,400 in 2020-2021) and their CYSHCN program is now working on an analysis of CYSHCN national priorities and social determinants of health by race/ethnicity.
Children’s Healthcare of Atlanta began sponsoring an annual oversample to produce reliable estimates of anxiety and depression by child age for the Atlanta metro area in 2021. As designed, over 1,000 interviews in the Atlanta metro were completed in 2021. These data will be used to support surveillance, healthcare planning, and treatment efforts.
