The COVID-19 pandemic has profoundly disrupted healthcare systems worldwide, creating unprecedented challenges for the management and education of chronic conditions such as diabetes. For professionals preparing for the Certified Diabetes Educator (CDE) exam, understanding the multifaceted impact of the pandemic is not merely an academic exercise—it is essential for delivering effective, patient-centered care in an evolving healthcare landscape. This article reviews how COVID-19 reshaped diabetes management and education, highlighting key implications for CDE candidates who must integrate resilience, technology, and adaptability into their practice.

Impact of COVID-19 on Diabetes Management

The pandemic forced healthcare systems to rapidly reorganize, often diverting resources away from routine chronic disease care. Patients with diabetes—already at higher risk for severe COVID-19 outcomes—faced significant barriers to maintaining optimal glycemic control. According to the CDC, disruptions in care led to increased hospitalizations and complications for many individuals with diabetes.

Disruptions in Routine Care Access

Lockdowns, clinic closures, and fear of infection drastically reduced in-person visits. Routine check-ups, lab tests (e.g., A1C), and scheduled medication adjustments were postponed or canceled. Many patients postponed elective procedures, including foot and eye exams, which increased the risk of long-term complications. For CDE exam candidates, this highlights the need to prioritize preventive care and develop contingency plans for crisis scenarios.

Medication and Supply Chain Shortages

Global supply chains were strained, leading to intermittent shortages of insulin, glucose monitoring strips, and other essential supplies. Patients rationed insulin or resorted to alternative medications without proper guidance. A WHO statement urged governments to maintain insulin supply, but gaps persisted. Educators must be prepared to counsel patients on emergency supply management and alternative brands.

Telehealth: Transformation in Monitoring

Telehealth emerged as a critical tool for continued care, enabling remote consultations, medication reviews, and real-time glucose data sharing through connected devices. However, adoption was uneven. Patients in rural areas, older adults, and those with low digital literacy struggled. CDE candidates should understand telehealth regulations (e.g., HIPAA-compliant platforms) and learn to coach patients on using glucometers, continuous glucose monitors (CGMs), and smartphones for virtual visits.

Behavioral and Lifestyle Changes

Pandemic stress, anxiety, and isolation contributed to hyperglycemia and weight gain. Physical activity dropped sharply as gyms closed and restrictions limited outdoor movement. Dietary patterns shifted—some patients ate more processed foods, while others experienced food insecurity. Sleep disturbances and mental health issues also compounded glucose variability. Educators need to incorporate psychosocial assessment and stress management into their toolkits.

Psychological and Social Factors

The pandemic exacerbated existing health disparities. Vulnerable populations—including racial and ethnic minorities, low-income individuals, and those with limited access to technology—faced higher COVID-19 morbidity and worse diabetes outcomes. Social determinants of health (SDOH) became more visible. The American Diabetes Association (ADA) provided resources for educators to address SDOH during the crisis. For the CDE exam, understanding how to tailor education to diverse, at-risk populations is critical.

Impact on Diabetes Education

Diabetes self-management education and support (DSMES) programs were severely disrupted as in-person group classes and individual sessions were suspended. Educators had to pivot quickly to virtual formats, often with minimal training. This section explores the transformation and its lasting effects on diabetes education.

Transition to Virtual Platforms

From webinars to one-on-one video calls, educators leveraged technology to continue delivering education. Many programs adopted a hybrid model—combining synchronous sessions with asynchronous content (e.g., videos, quizzes). Yet, not all patients had reliable internet or devices. The Association of Diabetes Care & Education Specialists (ADCES) issued guidance on implementing virtual DSMES. CDE candidates should be familiar with these best practices, including how to maintain engagement and assess learning remotely.

Digital Literacy and Health Equity

A major barrier was the digital divide. Patients with limited literacy or familiarity with technology struggled to access virtual education. Educators had to simplify instructions, provide phone-only options, and offer printed materials. Future CDEs must advocate for equitable access and design materials that are accessible across literacy and language levels.

Adapting Teaching Strategies

In-person education allows for hands-on demonstrations (e.g., insulin injection, glucose meter use). Virtual settings demanded new approaches—using videos, simulated scenarios, and teach-back methods. Educators learned to chunk information, use interactive polls, and engage participants through chat and Q&A. For the exam, candidates should understand how to apply adult learning principles to a virtual environment.

Opportunities for Broader Reach

Despite challenges, virtual education expanded access for patients who previously faced travel or time constraints. Recorded sessions allowed asynchronous learning. Educators could reach patients in remote locations. The pandemic accelerated the integration of digital health tools into DSMES, a trend that will likely continue.

Implications for CDE Exam Preparation

The pandemic reshaped the knowledge and skills required of diabetes educators. The CDE exam now reflects these changes, with increased emphasis on telehealth, emergency preparedness, psychosocial care, and technology. Candidates should review updated guidelines from ADCES, ADA, and the National Certification Board for Diabetes Educators (NCBDE).

Updated Guidelines and Protocols

Familiarize yourself with the ADCES Practice Paper on Telehealth in Diabetes Care and the ADA Standards of Care which were updated to address pandemic considerations. These documents outline best practices for remote monitoring, insulin dose adjustments, and patient engagement.

Case Studies and Scenarios

Expect exam questions that present real-world scenarios from the pandemic: e.g., managing a patient with erratic glucose due to stress and supply shortages, or designing a virtual education plan for a newly diagnosed patient with low digital literacy. Practice applying the ADCES7 Self-Care Behaviors® in these contexts.

Technology and Self-Management Tools

Be proficient in explaining CGMs, smart insulin pens, telehealth platforms, and mobile apps. Understand how to interpret data from devices and coach patients on troubleshooting. The exam may assess knowledge of data privacy in virtual care.

Conclusion: Building Resilience in Diabetes Care

The COVID-19 pandemic was a stress test for global diabetes care. It revealed vulnerabilities in access, equity, and continuity, but also sparked innovation in telehealth, remote education, and patient empowerment. For CDE candidates, these lessons are not transient—they define the future of diabetes education. By integrating pandemic-era adaptations into their practice, new educators can build more resilient, patient-centered care systems prepared for any crisis.
