Alberta Diabetes Atlas 2007 provides trends over time, across age and regional variation for DM & related conditions.
The prevalence & incidence of DM are increasing in Alberta, and especially among older adults.
People with DM have significantly higher rates of CV disease, eye disease, kidney disease, mental health disorders and overall health care use than people without diabetes.
Better primary care can reduce the burden on acute care
Local information will help local planning.
Key Messages…
Diabetes- Background Info.Diabetes- Background Info.
Body has difficulty making insulin and/or using the insulin that it produces.
Problematic because insulin is required to move glucose into cells so that it can be used by body tissues and organs.
Without insulin action, glucose remains in blood.
Diabetes- Background Info.Diabetes- Background Info.
When glucose remains in the blood, blood glucose levels can rise to dangerously high levels and result in acute complications.
Higher than normal blood glucose levels also can result in long-term organ damage and affect the eyes, kidneys and cardiovascular system.
Diabetic Retinopathy
End-Stage Renal Disease
Cardiovascular Disease
Usually occurs early in life during childhood or adolescence and is managed with insulin.
Accounts for approximately 5% of all diabetes cases.
Type 1 DiabetesType 1 Diabetes
Usually associated with onset after 30-40 years of age; however during the past decade, it has become much more prevalent in younger individuals.
Associated with many complications such as heart problems, kidney problems, eye disease etc.
Thought to be associated with lifestyle factors including physical inactivity and obesity.
Accounts for 95% of all diabetes cases.
Type 2 DiabetesType 2 Diabetes
Diabetes - Big Picture, Big BurdenDiabetes - Big Picture, Big Burden
Is a chronic disease affecting more than 7% of Canadians over 20 years of age.
Healthcare costs of patients with diabetes were projected to be in excess of $6 billion in 2006.
As people are getting diabetes earlier in life, they are also getting complications earlier.

“Public health surveillance is the ongoing, systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice, closely integrated with the timely dissemination of these data to those who need to know. . . . A surveillance system includes a functional capacity for data collection, analysis and dissemination…”

Alberta Diabetes Atlas 2007Key Findings & Policy Options
Key Findings & Options:
1. Primary prevention to reduce rising prevalence.
2. Secondary prevention to reduce complications.
3. Enhance Quality of Primary Care.
4. Enhance Access to Primary Care.
5. Recognize mental health burden.

How YOU can use the ADSS…How YOU can use the ADSS…
ADSS can be used by the Regions to more accurately assess what the burden of DM and it’s comorbidities are.
ADSS provides important information and specific numbers that can be included in Regional Health Authority business plans/performance reports.
Diabetes is one of the conditions expected in performance reports for all health regions in Alberta.
ADSS can help regions plan and evaluate new programs.
