SURVEY METHODOLOGY

What methodology was used?

A national consumer survey was conducted to learn more about the public’s attitudes and perceptions toward heart failure. The survey included a sample of 3,000 U.S. residents ages 18+.1

Results were weighted a priori (through survey sampling) and ad hoc (applied weights) to be representative of nationwide census on age and gender, with additional monitoring to ensure representation across ethnicity, income, etc.

These results represent a statistical accuracy of ±1.8%. All analysis was performed at a 95% confidence level.

Abbott was not revealed as the study’s sponsor.


When was the survey conducted?

The survey was conducted between March 11 to March 22, 2019.


What is the logic behind the “4 degrees of separation” statistic?

By using an equation that determines the average path length (i.e., degrees of separation) between two nodes (i.e., individuals) in a random network (i.e., population), the information gleaned from the survey results that 1 in 10 people are personally affected by heart failure, and the documented study that the average American knows 600 people, it can be determined that the average person is 4 degrees of separation from heart failure.

KEY FINDINGS

People are generally aware of heart failure, but don’t have enough information to take action.

  • 1 in 10 respondents said they are personally affected by heart failure, meaning that they either have heart failure themselves or know someone with heart failure. The average person is just 4 degrees of separation from heart failure.
  • Most people perceive heart failure as a very serious disease, but there is a disassociation between “heart failure” and softer diagnoses like “weak heart.”

Respondents said they desire information about heart failure but are unlikely to talk about it with the number one source for health information – their doctor.

  • Most respondents (65%) wish they knew more about heart failure, but only 1 in 5 are likely to speak to their health care provider about it.
  • People rely on their health care providers to bring up heart failure as a concern, however nearly half of respondents (45%) believe that only a cardiologist can diagnose heart failure.

People understand heart failure can be controlled, but they aren’t confident in identifying symptoms.

  • 56% of respondents believe that heart failure can be controlled if identified early, but only 1 in 5 said they would quickly recognize whether they were experiencing heart failure. That mirrors the findings that only 20% of respondents could correctly identify the majority of heart failure symptoms.
  • Only 1 in 3 people would know what to do if they suspected they were experiencing heart failure.

Among minority groups, awareness efforts have been effective, but have fallen short of empowering people to take action.

  • The incidence of heart failure is 4.6 per 1,000 persons in African Americans, and 3.5 per 1,000 persons in Hispanics, compared to 2.4 in Caucasian communities. And according to the survey results, Hispanic and African American respondents were more likely to correctly identify their racial demographic as being at risk for heart failure.
  • However, Hispanic and African American respondents are not any more likely to correctly recognize symptoms or know what to do if they thought they were experiencing heart failure.
  • Those who report being very concerned about their personal risk for heart failure represent potentially vulnerable populations. They are significantly more likely to be less educated, lower income and/or supporting a family.
  • And even if they are very concerned, a full third of people are unlikely to speak to their doctor about it.

Awareness and relevancy is key to spurring action.

  • In the next 12 months, 29% of respondents are very likely to try to learn more about heart health, and 35% of respondents are very likely to take actions to improve heart health. Those people are generally already more concerned about their potential risk and almost half are personally affected by heart failure or know someone who is.
  • In the same time period of 12 months, 48% of respondents are generally unlikely to try to learn about heart health and 40% of respondents are generally unlikely to take actions to improve heart health. Those people tend to be younger and primarily white. They perceive heart failure as mostly being a risk for older individuals. They are aware of heart failure but don’t know anything about it.
