About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Data Source: 
National Hospital Discharge Survey
Population Estimates
Changed Since the Healthy People 2020 Launch: 
per 10,000 (age adjusted—see Comments)
Baseline (Year): 
25.3 (2007)
Target-Setting Method: 
Minimal statistical significance
Target-Setting Method Justification: 
The target is the smallest improvement that results in a statistically significant difference when tested against the baseline value, assuming the same standard error for the target as the baseline.

Number of discharges with a principal diagnosis of asthma (ICD-9-CM code 493) among persons aged 65 years and over


Number of persons aged 65 years and over

Comparable Healthy People 2010 Objective: 
Retained from HP2010 objective
Data Collection Frequency: 
Methodology Notes: 

    Principal diagnosis is the diagnosis chiefly responsible for admission of the person to the hospital.

    FOR SINGLE DATA YEARS: Hospital discharge rates are calculated using the July 1 estimates of the civilian population from the Vintage matching the data year for the postcensal period based on the 2000 census. For example, July 1, 2007 civilian population for rates of data year 2007, the 2007 estimates from Vintage 2007 are used as the denominator for 2007 rates. Rates for 2010 are also calculated using the July 1 estimates based on the 2000 census.
