Albert Einstein

Evidence-informed best practices are based on quality evidence and should be implemented into practice to optimize outcomes.7 Listed below you will find best practices graded according to the type of evidence. To view a description of the types of evidence, click here.

To help you move from best evidence to best practice, click on the + button next to each best practice to find details on how to implement, as well as change ideas to test using a PDSA approach. 

Change ideas are specific and practical changes by experience and research that focus on improving specific aspects of a system, process or behaviour. To learn more about change ideas see the QI: Getting Started tab.

Measurement

How will we know if a change is an improvement? Measurement is one of the critical steps in a quality improvement (QI) initiative that assesses the impact of your tests of change. Quality indicators are used to measure how well something is performing. There are three types of quality indicators used to measure your QI efforts: outcome (indicators that capture clinical outcomes and or system performance), process (indicators that track the processes that measure whether the system is working as planned), and balancing indicators (indicators that ensure that changing one part of the system does not cause new problems in other parts of the system).

Type of Indicator Indicator of Quality Improvement How to Calculate:

numerator
__________

denominator
Targets/ Benchmarks How is This Indicator Used?
Outcome Percentage of patients with diabetes, aged 40 or over, with two or more glycated hemoglobin (HbA1c) tests within the past 12 months Number of patients with diabetes, aged 40 or over, with two or more glycated hemoglobin tests (HbA1c) within the past 12 months
Number of patients with diabetes aged 40 or over.

Equivalent measures are available for CHCs, nurse practitioner-led clinics and AHACs, extracted from electronic medical records (EMRs)
Targets: As high as possible (set by individual practices)

Background

Updated on November 17, 2015

Issue

Diabetes is a complex disease that can be a challenge to manage. In 2012, 6.5% (1.9 million) of Canadians aged 12 or older reported that they had diabetes.1 The prevalence of diabetes is typically lower in wealthier countries when compared to low- or middle-income countries.2 However, among OECD ( Organisation for Economic Co-operation and Development) member countries, Canada has one of the highest rates of diabetes at 9.2% (Figure 1).3

Many Canadians with diabetes will develop serious, potentially fatal diabetes-related complications including heart disease and stroke, visual impairment, kidney disease, foot ulcers, and amputations).2 Diabetes is managed by keeping blood sugar under control and this is the key to avoiding complications and discomfort.

Call to Action

Optimal glycemic control is fundamental to managing diabetes. Measuring HbA1c (haemoglobin A1c) determines average blood sugar levels and higher levels can indicate a greater risk for developing diabetes-related complications.

It is a valuable indicator of treatment effectiveness and testing at 6-month intervals is recommended when glycemic targets are consistently achieved.4 A recent study on a large multicentre data set (400,497 tests in 79,409 patients, 2008-2011) showed that the optimal testing frequency was 4 times per year.5
