Attributable Cost of Hypertension
 Globally estimated to consume 10% of health care costs in
developed countries. Indirect costs estimated at $ 3.6
trillion (USD in 2001) –estimated to be 4.5 to 15% of GDP in
high income countries
 In Canada, direct cost is $3,072 per person per year, and
indirect cost is $854.
 Antihypertensive prescription consume estimated 13% of
total drug costs in Canada.

Pan Canadian Hypertension Framework
 Public Health Agency of Canada contract to
Hypertension Canada
 Co-funded by CIHR Canada Chair in
Hypertension Prevention and Control
 Intent is to guide decision-making, planning
and alignment of efforts for the prevention
and control of hypertension in Canada
 Outlines set of 10 objectives and 7
recommendations to be implemented and
operationalized by 2020

Target Audiences
 All potential stakeholders in
hypertension prevention and
control :
non governmental
organizations
- government organizations
- health care professional
organizations
- scientific organizations
-
Hypertension Framework: Vision
 The people of Canada have…
- the healthiest blood pressure distribution,
- lowest prevalence and the highest rates of awareness,
treatment and control of hypertension, and
- the lowest burden of disease associated with blood
pressure
…of any nation in the world.
 Uses the Expanded Chronic Disease Management
Model

Framework Development
Proposed Targets for 2020 (1)
Objective
Currently
in 2020
1. The prevalence of hypertension among adults in
Canada
19%
13%
2. Adults in Canada are aware of the risk of
developing hypertension and of the lifestyle
factors that influence blood pressure.
?
90%
3. Adults in Canada are aware that high blood
pressure increases the risk of major vascular
disease (stroke, heart attack, dementia, kidney
failure, heart failure).
?
85%
4. People in Canada who have hypertension are
aware of their condition.
83%
95%
5. Those with hypertension are attempting to
follow appropriate lifestyle recommendations
62-82%
90%
15
Objectives for 2020 (2)
Objective
Currently
in 2020
8-10%
40%
7. People unable to be successfully treated for
hypertension through lifestyle therapy have
appropriate drug therapy
80%
87%
8. People with hypertension have their blood
pressure “under control”
66%
78%
6. Canadians initially diagnosed with hypertension
will become normotensive through lifestyle
therapy
9. Aboriginal populations have similar rates for
blood pressure health indicators as the general
population
10. Populations at higher risk have similar rates for
blood pressure health indicators as the general
population
Current status unknown for
physically measured BP
indicators, a higher prevalence
of diagnosed hypertension is
reported.
16
Overarching Recommendations
1. Build healthy public policy
2.
3.
4.
5.
6.
7.
Re-orient/redesign the health services delivery
system
Build partnerships to create supportive
environments and evolve the healthcare system
Strengthen community action
Develop personal skills for better selfmanagement
Improve decision support
Optimize information systems
17
Research Recommendations
A foundational role for research is integrated into the 7 core
recommendations
1. The role for independent research is recognized
2. An increasingly and potentially dominant role for strategic
team-based research is recognized.
3. Multiple critical research gaps identified in an ad-hoc
assessment
4. Development of a Comprehensive Research Strategy is
recommended with CIHR research pillars (biomedical, clinical,
health services and population)
5. Develop/support networks of researchers and collaborations to
identify and address specific gaps and research opportunities
18
Progress and Actions to Support Framework
Operationalization
 HSFC/CIHR Chair in Hypertension Prevention
and Control (Dr. Norm Campbell)
 Priority to advance policies to improve
healthy eating environment
 Established intersectoral leadership
committee, the Hypertension Advisory
Committee, to support implementation of
the Framework recommendations.
 National government and non-governmental
organizational support and endorsement
 Identify where they fit in the Framework and
what actions can be taken to contribute to
the vision, goals and implementation of
prioritized recommendations
 Sign onto the statement of support
Priority Recommendations
Build Healthy Public Policy
 Develop one comprehensive multi-sector strategy
whose goal is for people in Canada to meet the
nationally recommended benchmarks for physical
activity, smoke free environments and diet (including
the recommended dietary reference intakes for
nutrients, especially sodium).
 Recognizes the need for an all of government
approach
20
Policy opportunities (1)
 Setting targets and timelines for reducing
sodium, saturated and trans fatty acids,
and free sugars in processed foods with
close government monitoring and
oversight.
 Restricting unhealthy food and beverage
marketing to children
 Implementing healthy food procurement
policies.
 Implementing clear transparent conflict of
interest guidelines to ensure public health
food policies are free of commercial bias.
Policy Opportunities (2)
 Mandated clear easy to understand food package




labeling with health implications.
Taxing foods that have added sodium, saturated and
trans fatty acids, and free sugars to recuperate
health and other societal costs.
Reducing the cost and increasing the availability of
healthy food.
Defining ‘unhealthy’ foods.
Monitoring and evaluation of the health of our food
environment.
Priority Recommendations
Build partnerships to create supportive environments and
evolve the healthcare system
 Expand and maintain the partnerships whose
contributions have been integral to the current Canadian
successes in lowering and controlling hypertension.
 Build new partnerships to better integrate disease
management with population health promotion
 Engage all levels of government, health organizations
and healthcare professionals, non-government
organizations, academics, relevant institutions and
corporations/businesses.
