1. Chapter Overview
This chapter marks a shift in terminology from simply “Diabetes Education” to Self-Management Education (SME) and Self-Management Support (SMS). The addition of “Support” recognizes that education alone is often insufficient for sustaining behavior change. For the CDE exam, you must distinguish between the process of learning (SME) and the ongoing support required to maintain it (SMS).
2. Key Messages (The "Gold Nuggets")
The Power of Education: Structured education doesn’t just lower A1C; in people with Type 2 diabetes, it has been associated with a 44% reduction in all-cause mortality and a 20% reduction in first cardiovascular events.
SME vs. SMS:
SME (Education): A systematic intervention involving active participation to gain knowledge and skills.
SMS (Support): Activities that support the implementation and maintenance of these behaviours (e.g., coaching, peer support).
The Winning Combination: Combining SME and SMS is most advantageous for improving glycemic control, self-efficacy, and reducing diabetes distress.
Cognitive Behavioural Interventions: Using cognitive restructuring, problem-solving, and goal setting is more effective than didactic (lecture-style) teaching alone.
3. Self-Management Education (SME)
A. Evidence of Benefit
Clinical: Reductions in A1C, CV risk factors, and foot complications.
Economic: Lower health-care expenditures observed after 12 months.
Psychosocial: Improvements in quality of life, self-efficacy, and reduced diabetes distress.
B. Delivery Formats
Group vs. Individual: Group settings are effective for short-term control, but combining group interventions with individual follow-up results in lower A1C than either setting alone.
The Team Effect: Interventions using a combination of health-care professionals are superior.
Nurse + Team: Most effective decrease in A1C (-1.84%).
Nurse only: -0.80% decrease.
Other personnel only: -0.77% decrease.
C. Technology in SME
Internet/Web-based: Effective for improving glycemic control and knowledge compared to usual care.
Mobile Apps/Texting:
General mobile apps show a small beneficial effect on A1C (-0.5%).
Text messaging interventions specifically reported an A1C difference of 0.53% compared to usual care.
4. Tailoring Education
One size does not fit all. Tailoring is paramount.
Cultural Tailoring: Culturally appropriate education (language, dietary advice, faith traditions) results in A1C reductions of -0.2% to -0.5%.
Minority Populations: Individual, face-to-face programs with peer educators often show larger A1C reductions than group-based programs in these populations.
Literacy: Content geared toward low literacy/numeracy can successfully improve A1C and self-efficacy.
5. Self-Management Support (SMS)
SMS is defined as strategies that augment an individual’s ability to self-manage.
A. Key SMS Interventions & Efficacy
Peer Support:
Overall reduction in A1C: -0.57%.
Individual peer support is superior to group peer support (Individual reduction: -0.91%).
Community Health Workers:
In minority populations, access results in A1C decrease of -0.37% to -0.75%.
Diabetes Coaching:
Involves goal setting and frequent follow-up.
Associated with A1C reduction of -0.32%.
Telephone Follow-up:
A study of 4 phone calls in one year by a nurse educator resulted in an A1C 0.9% lower than those who did not receive calls.
6. Diabetes Canada Clinical Practice Guidelines Recommendations
These are the “Must Memorize” graded recommendations for the exam.
Timely Education: People with diabetes should be offered timely SME that is tailored to enhance self-care.
Grade A, Level 1A.
Cognitive-Behavioural: SME should incorporate interventions like problem-solving, goal setting, and self-monitoring.
Grade B, Level 2.
Format: SME interventions may be offered in small group and/or one-on-one settings.
Grade A, Level 1A for Type 2 Diabetes.
Support Strategies: Support should be offered to assist in maintaining self-management (Grade B, Level 2), specifically via:
Peer-led support or community support workers (Grade B, Level 2).
Diabetes coaching (Grade B, Level 2).
Telephone follow-up (Grade B, Level 2).
Technology: Internet-based programs, text messages, and mobile apps may be used to improve glycemic control.
Grade A, Level 1A for Type 2 Diabetes.
Cultural Competence: Culturally appropriate SME/SMS should be used to improve glycemic control.
Grade A, Level 1A.
