National P.A.D. Public Awareness Survey Background

• Lower extremity peripheral arterial disease
  (P.A.D.) is common, affecting up to 12 to 29 of
  the elderly and approximately 800,000 Canadians.
• Intermittent claudication is the most frequent
  symptom of P.A.D. and impairs quality of life and
  functional status.
• Individuals with P.A.D. suffer a 5-fold increased
  relative risk of a heart attack and stroke and
  total mortality that is 2-3 fold greater than
  those without P.A.D.
• Individuals with P.A.D. suffer combined annual
  rates of heart attack, stroke, and
  hospitalization that are comparable to, or
  greater than, rates observed in individuals with
  established coronary artery disease or stroke.
• but if the public is not aware of this risk,
  how can the risk be lowered?

National P.A.D. Public Awareness Survey Objectives

• Obtain baseline data to quantify public knowledge
  of the causes (risk factors), symptoms, and
  ischemic risks ? to life and limb ? of P.A.D.
• Results intended to serve as a benchmark so that
  improvements in awareness can be documented over
  time.

National P.A.D. Public Awareness Survey Methods

• 10-minute telephone survey used a Random Digit
  Dialing (RDD) sampling procedure to draw a
  national probability sample
• Survey administered to
• National cross-section of 501 Canadians ages 50
  years
• Conducted from 6/5/2006 to 7/5/2006
• Interviews were conducted in English and French
• Results were weighted by age and gender to
  reflect 2006 Canadian census estimates

Conclusions

• Few (about two in three) Canadians are aware of
  P.A.D.
• Those Canadians at risk for P.A.D. do not know
  its causes and thus cannot take steps to prevent
  it.
• Few Canadians know that having P.A.D. markedly
  increases ones short-term risk for heart attack,
  stroke, amputation and death.
• Those who are aware of P.A.D. rarely first learn
  about it from health care providers.

19
Conclusions

• P.A.D.-related knowledge is far below that of
  other comparable or lower risk cardiovascular
  diseases.
• These findings reinforce the need for national
  educational efforts on P.A.D.
• Health professionals, the media, the healthcare
  industry, and government agencies share a
  responsibility to work together to inform the
  public about this common cardiovascular disease.

The P.A.D. Coalition

• The P.A.D. Coalition aims to deliver consistent,
  evidence-based P.A.D. messages to the public and
  the health care community.
• New tools are available to help medical
  practices, hospitals, health plans and health
  systems educate their patients and clinicians
  about P.A.D.
