Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
From the 2008 National Health Interview Survey Heart Disease Supplement:
If you thought someone was having a heart attack, what is the BEST thing to do right away?
Persons are considered to be aware of the importance of calling 9-1-1 if they indicate that the best thing to do is call 9-1-1 (or another
emergency number). Persons are considered to be unaware of the importance of calling 9-1-1 if they indicate that the best
thing to do is advise them to drive to the hospital, advise them to call their physician, call spouse or family member, other, or don’t know.
This Indicator uses Age-Adjustment Groups:
Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.
In 2012, the original baseline was revised from 92.9 to 91.8 percent due to changes in how the response “don’t know” is handled. Previously responses of “don’t know” were excluded, but they are now included as lack of awareness. The target was adjusted from 94.9 percent to 93.8 percent to reflect the revised baseline using the original target-setting method.
