Reduce stroke deaths — HDS‑03 Data Methodology and Measurement

About the National Data

Data

Baseline: 37.1 stroke deaths per 100,000 population occurred in 2018

Target: 33.4 per 100,000

Numerator
Number of deaths with stroke as the underlying cause (ICD-10 codes: I60-I69).
Denominator
Number of persons.
Target-setting method
Percent improvement
Target-setting method details
10 percent improvement from the baseline.
Target-setting method justification
Trend data were evaluated for this objective, but it was not possible to project a target because the trend over the last decade was quadratic. The recent trend since 2013 was increasing, thus the analysis based on the last decade of data was not a reliable predictor given the recent shift in direction. A 10 percent improvement from the baseline was used to calculate a target. This method was used because recent trends suggested progress toward reducing stroke deaths is slowing in contrast to the progress observed in previous decades.

Methodology

Methodology notes

Death due to cerebrovascular diseases, ICD-10 codes: I60-I69.

FOR SINGLE DATA YEARS: Death rates are calculated based on the resident population of the United States for the data year involved. For census years (e.g. 2010), population counts enumerated as of April 1 are used. For all other years, populations estimates as of July 1 are used. Postcensal population estimates are used in rate calculations for years after a census year and match the data year vintage (e.g. July 1, 2011 resident population estimates from Vintage 2011 are used as the denominator for 2011 rates). Intercensal population estimates are used in rate calculations for the years between censuses (e.g. 1991-1999, 2001-2009). Race-specific population estimates for 1991 and later use bridged-race categories.

FOR MULTIPLE DATA YEARS: Death rates are calculated based on the sum of the resident populations for each of the data years involved (e.g. the denominator of a rate for 2008-2010 combined is the sum of the population estimates for 2008, 2009, and 2010). For census years (e.g. 2010), population counts enumerated as of April 1 are used. For all other years, populations estimates as of July 1 are used. Postcensal population estimates are used in rate calculations for years after a census year and match the data year vintage (e.g. July 1, 2011 resident population estimates from Vintage 2011 are used as the denominator for 2011 rates). Intercensal population estimates are used in rate calculations for the years between censuses (e.g. 1991-1999, 2001-2009). Race-specific population estimates for 1991 and later use bridged-race categories.
