Overcoming Barriers to CGM Adoption: A Guide for Medical Professionals

Continuous Glucose Monitoring (CGM) has revolutionized diabetes care, offering patients and healthcare providers real-time insights into glucose levels, patterns, and trends that can greatly improve glycemic control. The benefits of CGM are well-documented, including improved time-in-range (TIR), reduced HbA1c levels, and decreased incidences of hypoglycemia and hyperglycemia. Despite these clear advantages, CGM adoption rates remain lower than expected, with many patients hesitant or unable to make the transition from traditional glucose monitoring methods.

As medical professionals, understanding and addressing the barriers to CGM adoption is key to promoting its wider use. Whether it’s patient hesitation, cost concerns, or logistical hurdles, overcoming these challenges is crucial in helping more people benefit from this life-changing technology. In this blog, we will explore the most common barriers to CGM adoption and provide strategies to help medical professionals guide patients through the process of adopting CGM.

1. Lack of Awareness and Understanding of CGM

One of the most significant barriers to CGM adoption is a general lack of awareness and understanding of how CGM works and its potential benefits. Many patients are simply unaware of CGM as an option, and those who are may not fully grasp how it differs from traditional finger-stick blood glucose monitoring.

Patient Perception of CGM

Many patients assume that CGM is simply a more expensive or complex version of their existing glucose monitoring method. They may not realize that CGM provides continuous, real-time data and helps prevent dangerous glucose fluctuations with timely alerts. Moreover, patients may not understand how CGM improves time-in-range (TIR), reduces HbA1c, and gives them the ability to adjust their lifestyle or medications based on actionable insights.

How to Overcome This Barrier

• Educate Patients Early and Often: Take time to explain CGM during patient visits, emphasizing its benefits over traditional monitoring methods. Highlight how CGM provides real-time data, tracks trends, and offers proactive alerts for hypoglycemia and hyperglycemia. Reinforce that CGM offers a more comprehensive view of glucose patterns than finger-stick monitoring.
• Use Visuals and Demonstrations: When discussing CGM with patients, use visual aids or live demonstrations to show how CGM works. Walk patients through how the sensor is inserted, how the data is displayed, and what the device’s alerts look like.
• Share Success Stories: Share real-life examples of other patients who have successfully adopted CGM and experienced significant improvements in their diabetes management. This can help overcome skepticism and build confidence in the technology.

2. Fear of Technology and Device Complexity

For many patients, the idea of using a new medical device, particularly one that involves technology and data interpretation, can be intimidating. This is particularly true for older patients or those who are less familiar with technology. Concerns about the complexity of CGM devices—such as inserting the sensor, using the associated app, or interpreting the data—can create reluctance to switch from traditional glucose monitoring.

How to Overcome This Barrier

• Provide Hands-On Training: Offer one-on-one, hands-on training sessions for patients who are unfamiliar with CGM technology. Show them how to insert the sensor, set up the app or receiver, and interpret the data. Providing live support during the first few weeks of CGM use can build patient confidence and reduce anxiety about technology.
• Simplify the Process: Start by focusing on the basics. Rather than overwhelming patients with all the features of CGM devices, focus on the most essential functions, such as real-time glucose tracking and alerts. Gradually introduce more advanced features, like trend analysis and data sharing, as the patient becomes more comfortable.
• Involve Caregivers or Family Members: For patients who are not tech-savvy, involve a family member or caregiver in the training process. Having a trusted person help with device setup and monitoring can make patients feel more comfortable and less intimidated by the technology.

3. Concerns About Comfort and Sensor Wear

Many patients are concerned about the physical aspects of wearing a CGM device, such as discomfort with sensor insertion or irritation from adhesives. Additionally, some patients worry about the visibility of the device and how it may affect their daily activities, such as exercising, bathing, or sleeping.

How to Overcome This Barrier

• Reassure Patients About Sensor Insertion: While some patients may be hesitant about inserting a sensor under their skin, reassure them that modern CGM sensors are designed to be minimally invasive and virtually painless. Consider performing an insertion demonstration in the clinic to show how quick and easy the process is.
• Address Adhesive Concerns: For patients who experience skin irritation from CGM adhesives, offer suggestions such as using barrier wipes, hypoallergenic adhesives, or changing the sensor location to reduce skin irritation. Some patients may benefit from skin-prep products or sensor patches that enhance comfort and adhesion.
• Encourage Activity and Flexibility: Let patients know that CGM devices are designed to be worn during most activities, including exercise, bathing, and sleeping. Highlight that some CGM devices are waterproof and secure enough to stay in place during vigorous activity.

4. Cost and Insurance Coverage Challenges

Cost is one of the most frequently cited barriers to CGM adoption, particularly for patients who do not have comprehensive insurance coverage. While many private insurance companies, Medicare, and Medicaid cover CGM devices for patients with diabetes, there are still out-of-pocket expenses for sensors, transmitters, and receivers that may deter patients from adopting CGM.

How to Overcome This Barrier

• Verify Insurance Coverage: Help patients navigate the complexities of insurance coverage by verifying what their plan covers and explaining the steps required to get CGM devices covered. Many insurance providers require prior authorization or documentation of medical necessity, so assisting patients with these administrative tasks can make the process easier.
• Explore Financial Assistance Programs: Some CGM manufacturers offer patient assistance programs or discounts for uninsured or underinsured individuals. Encourage patients to explore these options and offer to help them apply for financial assistance if needed.
• Focus on Long-Term Benefits: While the initial cost of CGM may seem high, emphasize the long-term benefits of using the device, including better glycemic control, fewer diabetes-related complications, and improved quality of life. Better diabetes management can reduce the costs associated with hospital visits, medication adjustments, and complications like diabetic ketoacidosis (DKA) or hypoglycemia.

5. Resistance to Change and Disruption of Routine

Some patients are resistant to change, especially if they have been managing their diabetes using finger-stick monitoring for many years. They may worry that switching to CGM will disrupt their established routines or add complexity to their daily lives.

How to Overcome This Barrier

• Gradual Introduction: For patients resistant to change, consider introducing CGM gradually. Start by encouraging them to use the device for specific periods, such as overnight or during physical activity, and gradually increase usage over time. This allows patients to experience the benefits without feeling overwhelmed.
• Highlight Convenience: Emphasize how CGM simplifies diabetes management by reducing the need for frequent finger sticks and providing real-time data without manual intervention. Explain how CGM can offer peace of mind, especially by alerting patients to dangerous glucose levels while they sleep or engage in other activities.
• Offer Ongoing Support: Resistance to change often stems from uncertainty. Providing continuous support through follow-up appointments, phone check-ins, and access to educational resources can help patients feel more confident about integrating CGM into their diabetes management routine.

6. Misunderstanding the Value of Data

While CGM provides a wealth of data, some patients may not understand how to interpret that data or how it can be used to improve their health. Without understanding how to use CGM data effectively, patients may view CGM as a burden rather than a tool for better diabetes control.

How to Overcome This Barrier

• Simplify Data Interpretation: Teach patients to focus on the most relevant data points, such as glucose trends, time-in-range (TIR), and personalized high and low alerts. Encourage patients to look at patterns rather than individual readings, and provide guidance on how to make simple adjustments to diet, activity, or medications based on the data.
• Use Data for Shared Decision-Making: Involve patients in shared decision-making by using CGM data during appointments to adjust their treatment plans. Show them how the data can inform decisions about insulin dosing, diet modifications, and lifestyle changes, making the data feel more relevant and actionable.
• Provide Educational Resources: Offer patients access to educational materials, such as online tutorials, printed guides, or mobile apps, that explain how to interpret CGM data and apply it to their diabetes management.

7. Provider Hesitation

In some cases, barriers to CGM adoption come from healthcare providers themselves. Providers may be hesitant to prescribe CGM due to concerns about accuracy, cost, or the additional time required to interpret CGM data during patient visits.
