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 they produce.

Problematic because insulin is required to move glucose into cells so that it can be used by body tissues and organs.

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 5-10% 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 90-95% 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 5% of Canadians over 20 years of age.

Healthcare costs of patients with diabetes are projected to be in excess of $6 billion in 2006.

As people are getting diabetes earlier in life, they are also getting complications earlier in life.

“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…”

KEY FINDING POLICY OPTIONS

6. Screening for diabetic eye disease is an important strategy in preventing blindness; despite

strong evidence, the frequency of eye examinations by experienced

professionals is lower than suggested by practice guidelines.

• Increase awareness of the need for regular eye examinations by actively disseminating the

guidelines to both patients and providers.

• Enhance surveillance to include care provided by all eye care professionals.

• Consider increased use of teleophthalmology to enhance access for required eye

examinations in northern and non-metro health regions.

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.

6. Enhanced eye care for diabetes.

7. Diabetes in First Nations People.

8. Enhance scope and depth of DM surveillance.

What is missing? What is next?

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.

How can YOU use the ADSS?

1. Active dissemination to Regions: Local presentations

2. Ongoing Newsletters
