About the National Data
Baseline: 118.4 emergency department visits for asthma per 10,000 children under 5 years occurred in 2016-18
Target: 64.3 per 10,000
Minimal statistical significance
FOR MULTIPLE DATA YEARS: Emergency department visit rates are calculated based on sum of July 1 estimates of the civilian noninstitutionalized populations for each of the data years involved (e.g., the denominator of a rate for 2016-2018 combined is the sum of the population estimates for 2016, 2017, and 2018). The population estimates are from the Vintage matching the data year for the postcensal period based on the 2010 census (e.g., July 1, 2016 civilian noninstitutionalized population estimates from Vintage 2016). July 1, 2020 population estimates based on the 2010 census are used for 2020.
In 2022, the baseline was revised from 129.6 per 10,000 in 2013-15 to 118.4 per 10,000 in 2016-18 because NHAMCS completed the transition from ICD-9-CM to ICD-10-CM in 2016. The target was revised from 65.7 per 10,000 to 64.3 per 100,000 using the original target setting method.
