What structured outpatient diabetes education program with telehealth follow‑up should be implemented to improve hemoglobin A1c levels in patients with diabetes?

Structured Outpatient Diabetes Education with Telehealth Follow-Up for HbA1c Improvement

Implement a structured diabetes self-management education and support (DSMES) program consisting of >10 hours of education delivered over 6-12 months, utilizing a hybrid model of initial in-person education followed by telehealth-based follow-up with interactive communication (text messaging, phone calls, or video conferencing) to achieve clinically significant HbA1c reductions. 1, 2

Core Program Structure

The most effective approach combines:

• Initial in-person diabetes education session to establish baseline knowledge and rapport
• Structured curriculum delivered by certified diabetes care and education specialists (CDCES) or qualified team members including registered dietitian nutritionists, nurses, or pharmacists 1
• Total education time exceeding 10 hours spread across 6-12 months for optimal outcomes 1
• Regular telehealth follow-up using text messages, phone calls, or video conferencing to reinforce education and provide ongoing support 2, 3

Evidence-Based Outcomes

The 2025 ADA Standards of Care establish that telehealth-based DSMES interventions produce A1C reductions of 0.30 percentage points (95% CI 0.42 to 0.19) compared with control, with outcomes comparable to or better than traditional in-person care 1. This is supported by real-world implementation data showing a 1.7% mean HbA1c decrease when structured education is combined with telehealth follow-up messaging 3, and a 2.59% reduction with hybrid in-person/telemedicine models 4.

Implementation Algorithm

Step 1: Patient Identification and Enrollment

• Target patients with HbA1c ≥8% for intensive intervention 3
• Assess for social determinants of health, technology access, and individual preferences 1
• Evaluate annually or when treatment goals are not met, whichever is more frequent 1

Step 2: Initial In-Person Education

• Conduct comprehensive diabetes education covering disease pathophysiology, medication management, nutrition, physical activity, and self-monitoring
• Utilize both individual and group formats (slight benefit when combining both approaches) 1
• Tailor content to cultural background, literacy level, and age appropriateness 1
• Address psychosocial factors and incorporate behavioral change strategies 1

Step 3: Telehealth Follow-Up Protocol

• Schedule regular telehealth contacts (text, phone, or video) throughout the 6-12 month period
• Use interactive communication that facilitates bidirectional dialogue between providers and patients 2
• Incorporate medication adjustment capabilities when appropriate 2
• Provide ongoing support for goal-setting, problem-solving, and accountability 5

Step 4: Team Composition

Engage an interprofessional team including:

• Primary care clinician
• CDCES (certified diabetes care and education specialist) or BC-ADM (board certified in advanced diabetes management) 1
• Registered dietitian nutritionist
• Consider community health workers or peer educators for ongoing support 1

Critical Implementation Considerations

Telehealth should complement, not replace, in-person visits for optimal glycemic management 2. The hybrid model is superior to telehealth-only approaches, as demonstrated by the significant HbA1c reductions (2.16-3.17%) achieved when initial in-person education is followed by telemedicine support 4.

Greater engagement produces greater A1C reductions 1, so design your follow-up protocol to maximize patient interaction. Text messaging and phone-based follow-up are particularly effective for maintaining engagement between formal visits 3.

Address barriers proactively: While technology access is rarely limiting 5, competing responsibilities and perceived lack of need for education are common reasons for non-participation 5. Frame the program as ongoing support rather than remedial education.

Program Duration and Intensity

The evidence strongly supports programs exceeding 10 hours over 6-12 months with ongoing support 1. Shorter programs or those without follow-up support show diminished effectiveness. The sustained benefit is demonstrated by maintained HbA1c improvements at 4-6 month follow-up 3, 6, with some studies showing durability up to 24 months when support continues 7.

Quality Metrics

Monitor these outcomes to assess program effectiveness:

• Primary outcome: HbA1c reduction (expect 1.2-2.6% decrease) 3, 4, 6
• Medication adherence
• Appointment attendance rates
• Emergency department utilization
• Patient satisfaction scores (typically >95% with well-designed programs) 6, 5

For rural or underserved populations, telehealth is particularly effective at removing geographic and transportation barriers while maintaining clinical effectiveness 2. The evidence for glycemic management via telehealth in these populations is especially robust 2.
