Video Resource: ADA Standards of Medical Care: Recommendations for Continuous Glucose Monitoring
The American Diabetes Association (ADA) Standards of Medical Care represent the latest evidence-based recommendations for guiding clinical practice. According to the most recent edition of these guidelines, Level A evidence from the MOBILE study supports the use of real time continuous glucose monitoring (rtCGM) in patients with insulin-treated type 2 diabetes (T2D) regardless of regimen. The findings from the MOBILE study likewise demonstrate the value of rtCGM across typically underserved demographics of patients impacted by social determinants of health (SDOH). Taking the ADA recommendations into consideration, payers are formulating coverage policies that facilitate appropriate access to rtCGM, improved outcomes in T2D, and proven per-member-per-month (PMPM) cost savings.

Comparing Real-Time and Intermittently Scanned Continuous Glucose Monitoring in Adults with Type 1 Diabetes (ALERTT1): a 6-month, Prospective, Multicenter, Randomized Controlled Trial
Source: The Lancet – June 2021
Key Takeaways:
The ALERTT1 trial is the first 6-month, multicenter, prospective, randomized controlled trial comparing rtCGM with isCGM in 254 adults with type 1 diabetes, who previously used isCGM. Mean HbA1c was 7·4% (58 mmol/mol) and a minority of the study population was hypoglycemia unaware (44 [17%] people) or had a history of severe hypoglycemia (29 [11%]). Most (205 [81%]) were treated with multiple daily injections. Findings showed that in an unselected group of people with type 1 diabetes, 6-month use of rtCGM with alert functionality improved time in range (70–180 mg/dL [3.9–10.0 mmol/L]), while HbA1c, time in clinically significant hypoglycemia (< 54 mg/dL [3.0 mmol/L), and hyperglycemia (180 mg/dL [10.0 mmol/L]) were reduced. Additionally, more people on rtCGM achieved glycemic targets as defined by international consensus guidelines, and had less frequently severe hypoglycemia. Moreover, rtCGM users experienced less hypoglycemia worry and higher treatment satisfaction at the end of study.

American Association of Clinical Endocrinology Clinical Practice Guideline: The Use of Advanced Technology in the Management of Persons With Diabetes Mellitus
Source:
The American Association of Clinical Endocrinology (AACE) with a task force of medical experts developed evidence-based guideline recommendations regarding the use of advanced diabetes technology in clinical settings. The guidelines reveal that ensuring universal access to advanced diabetes technologies is anticipated to result in improved glycemia and allowing more persons with diabetes to achieve glycemic targets, improve quality of life, and potentially reduce burden of care. Furthermore, diabetes technology can improve the efficiency and effectiveness of clinical decision-making.

Benefits of Real-Time Continuous Glucose Monitoring in Pregnancy
Source: Diabetes Technology and Therapeutics
Key Takeaway: The CONCEPTT (CGM in pregnant women with type 1 diabetes) trial provided high-quality, randomized-controlled trial data demonstrating that the use of real-time CGM was associated with lower HbA1c at 34 weeks, suggesting improved maternal glucose levels during the late second and early third trimesters.7 Importantly, this was accompanied by 7% higher time in range (TIR) and 5% lower time above range (TAR) without increasing maternal hypoglycemia. Beyond impacting surrogate markers of maternal glycemia, using CGM led to clinically significant reductions in large for gestational-age infants, neonatal hypoglycemia, and neonatal intensive care unit (NICU) admissions.7 A systematic review combining data from CONCEPTT with that of the type 1 diabetes arm of the GlucoMOMS trial also showed evidence for a reduction in preeclampsia.7–9

Change in HbA1c and Quality of Life with Real-time CGM Use by People with Insulin-Treated Diabetes in the Landmark Study
Source: Diabetes Technology and Therapeutics
Key Takeaway: The Landmark study demonstrated significant glycemic and QoL benefits for first time CGM use among individuals using intensive insulin therapy to manage either T1D or T2D. After approximately 12 weeks of Dexcom G6 use, participants had a mean absolute reduction in HbA1c levels of 1.1%, and more than half of those with initial HbA1c values >7% experienced absolute HbA1c reductions of >1%. The reduction in HbA1c observed in Landmark was similar for patients with T1D and T2D and was more pronounced for participants with higher baseline HbA1c, consistent with observations from the DIAMOND randomized controlled trial. Significant reductions in diabetes distress and hypoglycemic concerns were also observed. In the Landmark study, there was no standardized training or intervention at CGM initiation, suggesting that the glycemic benefits can be realized without formal instruction.

Key Takeaway: The role of real-time continuous glucose monitoring (rtCGM) is an essential component of telemedicine visits for people with diabetes. This observational study demonstrated that people with type 2 diabetes (T2D) participating in a virtual diabetes clinic can successfully insert and use Dexcom rtCGM without in-office training. The use of rtCGM was associated with a significant improvement in HbA1c at 10 months in those not meeting the ADA treatment target, independent of insulin use. In addition, there was a large shift in the percentage of participants meeting the HEDIS HbA1c target of <8.0% at follow-up; this may have important clinical and economic implications.

Key Takeaway: In December 2020, NICE reviewed the evidence and changed the recommendations on intermittently scanned CGM (isCGM, also commonly referred to as flash) and continuous glucose monitoring during pregnancy for women with type 1 diabetes.
|
Recommendations for Managing Diabetes During Pregnancy- |
|
| 1.3.17 |
Offer continuous glucose monitoring (CGM) to all pregnant women with type 1 diabetes to help them meet their pregnancy blood glucose targets and improve neonatal outcomes. |
| 1.3.18 |
Offer intermittently scanned CGM (isCGM, commonly referred to as flash) to pregnant women with type 1 diabetes who are unable to use continuous glucose monitoring or express a clear preference for it. |
| 1.3.19 |
Consider continuous glucose monitoring for pregnant women who are on insulin therapy but do not have type 1 diabetes, if:
|
| 1.3.20 |
For pregnant women who are using isCGM or continuous glucose monitoring, a member of the joint diabetes and antenatal care team with expertise in these systems should provide education and support (including advising women about sources of out-of-hours support). |
For a short explanation of why the committee made the 2020 recommendations and how they might affect practice, see the rationale and impact section on flash and continuous glucose monitoring on pages 35-36 in the Guideline. Full details of the evidence and the committee’s discussion are in evidence review A: continuous glucose monitoring.

Continuous Glucose Monitoring (CGM): Removing Obstacles and Improving Access for Health Equity Webinar
Presented by:
Daniel DeSalvo, MD
Assistant Professor of Pediatrics in the Section of Diabetes and Endocrinology
Baylor College of Medicine/Texas Children’s Hospital
Houston TX
In diverse and underserved populations research shows there are racial and ethnic disparities in diabetes outcomes. Disparities in diabetes technology use has the greatest influence on glycemic disparities between Black, Hispanic and Non-Hispanic White individuals. A study recently published in Diabetes Care found that lower socio-economic status was associated with lower rates of diabetes technology use and higher levels of A1C. Importantly, this gap in technology has widened over time. Data published from the T1D exchange, shows that across all age groups, individuals that use continuous glucose monitoring (CGM) have lower A1C levels compared to those who don’t use CGM.
This webinar will highlight the improvements in glycemic and psychosocial outcomes, along with best practices from recent research findings that support the use of CGM in diverse populations.

Key Takeaway: Recent data from a prospective, randomized study conducted by Intermountain Health suggests that real-time CGM can reduce healthcare utilization and decrease the overall cost of care compared to SMBG. Participants reported that real-time CGM data were helpful in modifying their nutrition, physical activity, stress, and medication adherence.
A Randomized Trial of Closed-Loop Control in Children with Type 1 Diabetes
Source:
Key Takeaway: In a 16-week trial funded by the NIDDK and Tandem Diabetes Care, 101 children ages 6-13 with type 1 diabetes were randomized to a closed-loop system of insulin delivery (n=78) or the control group (n=23) where patients used a sensor-augmented insulin pump. Children using the closed-loop system, consisting of a t:slim X2 insulin pump with Control-IQ technology and a Dexcom G6 CGM, saw a significant time in range (TIR) improvement (target 70-180 mg/dL) from 53% at baseline to 67% (equivalent to 3.4 more hours per day; p<0.001) at the end of the study. The control group saw a smaller TIR increase from 51% at baseline to 55% at the end of the study. Notably, TIR increased most significantly overnight with children reaching 80% overnight TIR compared to 54% in the control group. The treatment effect was evident in the first month and appeared consistent over 4 months. Control-IQ technology demonstrated benefits across a broad range of baseline characteristics and proved easy to use for children and their parents.

Key Takeaway: Six-month, multicenter, randomized controlled trial using the Dexcom G5. The baseline population had diverse racial/ethnic backgrounds (38% Hispanic or non-white), high baseline HbA1c levels, and 41% had public health insurance. The trial showed a 0.4% A1c advantage in favor of CGM over BGM (p=0.01; baseline: 8.9%). Moreover, more than twice as many in the CGM group as compared to the BGM group achieved an A1c reduction ≥0.5% (44% vs. 21%, p=0.005) and over four-times as many participants in the CGM group vs. the BGM group saw an A1c reduction of ≥1% (25% vs. 6%, p=0.003). The CGM group also saw a 1.7 hour/day advantage vs. BGM on time-in-range (70-180 mg/dl) (p<0.001). Over two-thirds of the CGM group were using CGM at least five days/week by the end of the six-month study – the highest CGM use observed for adolescents in a study to date. Moreover, the CGM group reported significantly higher glucose monitoring satisfaction, measured via the Glucose Monitoring Satisfaction Survey score, at 26 weeks than the BGM group . Newer models of CGM devices that eliminate fingerstick calibration should lead to improved wearability and glycemic control even beyond the measured benefits observed in this trial. Improved glycemic control early in diabetes duration may prevent diabetes complications later in adulthood, making CGM an attractive option for this population.
Effect of Continuous Glucose Monitoring on Hypoglycemia in Older Adults With Type 1 Diabetes A Randomized Clinical Trial
Source: Journal of the American Medical Association
Key Takeaway:Older populations are more prone than younger populations to severe hypoglycemic episodes, which in turn contribute to dementia, risk of falls, glycemic variability, and mortality. To study whether CGM could reduce hypoglycemia incidence, Pratley and colleagues performed a randomized clinical trial that compared the effect of CGM (n = 103) with BGM (n = 100) in older adults (median age, 68 years) with type 1 diabetes in 22 diabetes centers across the US. The primary outcome was reduction in hypoglycemia (glucose <70mg/dL) over 6 months. Results showed that the median time in hypoglycemia was reduced from 73 minutes to 39 minutes per day in the CGM group compared with no change (from 68 minutes to 70 minutes per day) in the BGM group, an adjusted between group reduction of 27 minutes per day (95% CI, −40 to −16 min/d). Additionally, the median percentage of time with blood glucose levels below the range for severe hypoglycemia (glucose <54mg/dL) reached the goal per international guidelines (<14min/d in older adults). Moreover, only 1 severe hypoglycemic event (glucose <54mg/dL) occurred in the CGM group vs 10 in the BGM group, with 5 of those events involving seizure or loss of consciousness. 83% of participants in the CGM group used CGM at least 6 days per week during month 6 and the results did not differ by level of cognitive impairment, education level, or age. In summary, CGM reduced the time spent in the severe hypoglycemic range, which has health care use, mortality, morbidity, and economic benefits.
Improved well-being and decreased disease burden after 1-year use of flash glucose monitoring (FLARE-NL4)
Source: BMJ Open Diabetes Research and Care
Key takeaway: A real-life observational study demonstrated the effectiveness of flash glucose monitoring (FGM) in participants with diabetes over a 12 month period. Data from the Netherlands Nationwide Registry showed the use of FGM results in improved well-being, decreased disease burden, and is associated with a 0.4% reduction of HbA1c after 12 months (p < 0.001). Results from a patient-reported outcome measures questionnaire revealed significant reductions in work absenteeism and diabetes-related hospital admissions.
Leveraging Diabetes Health Technology in Managed Care and Coverage Considerations for Real-Time Continuous Glucose Monitoring
Announcing a new white paper based on key findings from the Therapeutic CGM Health Care Stakeholder Summit held on November 7, 2019, in Washington, DC. The stakeholder panel included payer and employer leadership along with clinical experts in the field of endocrinology. The purpose was to gather input pertinent to the coverage and application of therapeutic continuous glucose monitoring (CGM) in managed care settings. Clinical evidence supporting the clinical and economic value of rtCGM was presented and the insights of these health care stakeholders were captured en route to formulating coverage policy recommendations for the future. This input is intended to advance the uptake and appropriate coverage of evidence-based health technology interventions by managed care organizations (MCOs) and various payers.

Clinical Implications of Real-time and Intermittently Scanned Continuous Glucose Monitoring
Source: Diabetes Care
Key Takeaways: CGM has emerged as a new standard of care for individuals with insulin-treated diabetes. Two types of CGM systems are now available: real-time CGM (rtCGM) and intermittently scanned (isCGM). rtCGM systems automatically transmit a continuous stream of glucose data to the user, provide alerts and active alarms, and transmit glucose data in real time to a smart phone and/or other display device. The current isCGM system provides the same type of data but requires the user to purposely scan the sensor to obtain information, and it does not have alerts and alarms. Both CGM technologies have significant advantages over self-monitoring of blood glucose; however, differences in the features and capabilities of the two approaches must be considered when guiding patient selection of the system that meets their individual needs.
Continuous Glucose Monitoring: An Emerging Standard of Care
Source: American Journal of Managed Care
Key Takeaway: The use of CGM is proven to reduce A1C, reduce time spent in hypo- and hyperglycemia and improve time in range (TIR) for Type 1 and Type 2 patients using intensive insulin, defined as multiple daily injections of insulin or getting insulin through an insulin pump. This has resulted in guidelines and recommendations from professional societies such as the ADA recommending CGM as a standard of care for Type 1 and Type 2 patients using intensive insulin. CGM is an important monitoring tool that is best accessed by providers and patients in the pharmacy channel.
Continuous Glucose Monitoring with Dexcom G6
Source: First Report Managed Care
Key Takeaway: Diabetes is a complex chronic disease that for some Type 1 and Type 2 patients requires the use of intensive insulin defined as 3 or more injections/day or insulin through a pump. The adverse consequences of using insulin are severe and can result in a coma, seizure or even death which leads many patients and caregivers deciding to use less insulin as prescribed preventing achievement of glycemic goals. Real-time CGM with alerts/alarms, remote monitoring and reporting can help patients use their insulin safely and effectively to achieve lower A1Cs, spend less time in hypo- and hyperglycemia and spend more time in range (TIR). The benefits of CGM are seen when it is used to make diabetes treatment decisions such as insulin dosing, diet and lifestyle in a timely manner. Accessing CGM devices via a pharmacy benefit allows patients to start CGM faster, stay safe while using insulin and engage pharmacists, providing additional support and interventions that have been shown to improve diabetes outcomes.
Clinical Targets for Continuous Glucose Monitoring Data Interpretation: Recommendations From the International Consensus on Time in Range
Source: Diabetes Care
Key Takeaway: Successful utilization of CGM technology in routine clinical practice remains relatively low due to a lack of clear and agreed-upon glycemic targets that both diabetes teams and people with diabetes can work toward. In February 2019, the Advanced Technologies & Treatments for Diabetes (ATTD) Congress convened an international panel of physicians, researchers, and individuals with diabetes who are expert in CGM technologies to address this issue and established targets for time in range (TIR), time below range (TBR) and time above range (TAR). These are metrics that only CGM can measure and overcome the limitations of metrics such as A1C which are reflective of a 3 month average of glycosylated hemoglobin and does not account for day to day glycemic variability or factors such as anemia which can skew A1C low.

Real Time CGM Studies: Effect of Continuous Glucose Monitoring on Glycemic Control in Adults with Type 1 Diabetes Using Insulin Injections – The DIAMOND Randomized Clinical Trial
Source: Journal of the American Medical Association
Key Takeaway: In the DIAMOND RCT, patients using multiple daily injections of insulin with type 1 diabetes who were randomly assigned to real-time CGM (rtCGM) had improved glycemic control vs. the SMBG group. This benefit was seen across patient groups regardless of baseline A1C, age, education level, or math ability. In addition, the rtCGM group spent 79% less time in nocturnal hypoglycemia, and also demonstrated a greater increase in hypoglycemic confidence and a greater decrease in diabetes distress vs. the SMBG group.
Baseline Glycated Hemoglobin Values Predict the Magnitude of Glycemic Improvement in Patients with Type 1 and Type 2 Diabetes: Subgroup Analyses from the DIAMOND Study Program
Source: Diabetes Technology & Therapeutics
Key Takeaway: Among the real-time CGM (rtCGM) users, the change in HbA1c was greatest in the highest HbA1c subgroup with similar decreases seen in both the T1D and T2D groups. Notably, adherence remained high in those with baseline HbA1c > 9% and the improvements seen were achieved without the need for additional medications. Thus, the costs of rtCGM in patients with high HbA1c may be offset by avoiding treatment intensification and the longer-term savings achieved by lowering HbA1c levels in poorly controlled diabetes populations.
Continuous Glucose Monitoring vs Conventional Therapy for Glycemic Control in Adults with Type 1 Diabetes Treated with Multiple Daily Insulin Injections – The GOLD Randomized Clinical Trial
Source: Journal of the American Medical Association
Key Takeaway: In the GOLD trial, glycemic control was improved with use of rtCGM compared with conventional treatment; however, increases in A1C and hypoglycemic events occurred when patients reverted back to SMBG during the crossover/washout period, suggesting that the effectiveness of CGM depends on uninterrupted use during treatment with MDI. Additionally, the study showed reductions in severe and nocturnal hypoglycemia as well as in glycemic variability and improved hypoglycemic confidence for rtCGM users.

Key Takeaway: This 6 month randomized trial showed use of a closed-loop system using the t:slim X2 insulin pump with Control-IQ Technology, (Tandem Diabetes Care) and a continuous glucose monitor (Dexcom G6, Dexcom) was safe and effective compared to sensor-augmented pump therapy (SAP). Participants in the closed-loop group achieved 70% time in range overall which meets the International Consensus Guidelines for people with diabetes. The closed-loop group also achieved significant improvements in hyperglycemia, HbA1c, mean glucose, and hypoglycemia (< 70 mg/dL < 54 mg/dL) as compared with the SAP group. Glycemic benefits were seen in the first month of the trial and were sustained over the entire 6-month period. Over 90% of participants said they trusted the device and found Control-IQ technology easy to use.

Advancing Glycemic Management in People with Diabetes
Source: The IQIVA Institute
About the report: The incorporation of time in range (TIR) metrics alongside HbA1c is expected to enhance the way in which diabetes is managed in the future, and subsequently, reduce the overall societal and economic burden. To assess the value of improving TIR from its current state to the minimum consensus target of 70% and 80% TIR, the IQVIA Core Diabetes Model was used to estimate cost reductions in complications and costs associated with improving TIR. Using this model, improvements in TIR were estimated to reduce the risk of developing diabetes-related complications resulting in a conservative reduction of $2.1-7 billion in costs over a 10-year period, based on the relationship between TIR and HbA1c. The addition of incrementally reducing hypoglycemic events in people with Type 1 Diabetes by 40% and improving TIR to 80% generated a total 10-year cost reduction of $6.7-9.7 billion. This reduction in costs represents a conservative estimate.

A Cost Offset Analysis (COA) Comparing Real-Time Continuous Glucose Monitoring (RT-CGM) With Intermittent Scanning Continuous Glucose Monitoring (IS-CGM) in Type 1 Diabetes (T1D) Subjects With Impaired Hypoglycemia Awareness in Eight Countries
Source: Value in Health. 2019: Volume 22 S572. doi: 10.1016/j.jval.2019.09
Key Takeaway: A recent RCT comparing an rt-CGM and is-CGM device demonstrated differences in %TIR over several glucose ranges allowing for projection of potential clinical outcomes. A COA was performed comparing these clinical cost offsets for rt-CGM and is-CGM in people with T1D (n=2,000) and impaired awareness of hypoglycemia (IAH; ~30% of people with T1D), applied to eight countries each over a one-year period. The demonstrated differences in %TIR spent at low, optimal, and high glucose ranges are likely to translate into significant clinical and economic benefits for rt-CGM compared with is-CGM.

Centers for Medicare & Medicaid Services (CMS) Local Coverage Determination for Therapeutic CGMs
Source: Centers for Medicare & Medicaid Services
Key Takeaway: CMS expanded Medicare coverage for therapeutic CGMs. Most notably, eliminating a requirement that beneficiaries use four fingerstick tests per day prior to accessing CGM. According to the local coverage determination, “there is no evidence to support that frequent SMBG (≥4 times per day) as a prerequisite for initiating CGM use is predictive of improved health outcomes”.
New Coverage Criteria (Effective July 18, 2021)
The revised LCD indicates that Medicare coverage for CGMs will be available if the beneficiary meets the following criteria:
- The beneficiary has diabetes mellitus; and,
- The beneficiary is insulin-treated with multiple (three or more) daily administrations of insulin or a continuous subcutaneous insulin infusion (CSII) pump; and,
- The beneficiary’s insulin treatment regimen requires frequent adjustment by the beneficiary on the basis of BGM or CGM testing results; and,
- Within six (6) months prior to ordering the CGM, the treating practitioner has an in-person visit with the beneficiary to evaluate their diabetes control and determined that criteria (1-3) above are met; and,
- Every six (6) months following the initial prescription of the CGM, the treating practitioner has an in-person visit with the beneficiary to assess adherence to their CGM regimen and diabetes treatment plan.
Current Eligibility Requirements for CGM Coverage Are Harmful, Costly, and Unjustified
Source: Diabetes Technology and Therapeutics
Key Takeaway: There is growing and compelling evidence that CGM coverage should be offered to all patients who can benefit from this technology regardless of diabetes type and history of SMBG use. The current restrictions, which are based on outdated evidence and questionable assessments, are not supported in the literature. Moreover, they ignore the burden frequent SMBG places on individuals. Given the growing prevalence of diabetes, the persistent preponderance of individuals with suboptimal glycemic control, and the exorbitant and largely preventable cost of diabetes complications, opinion-based constraints should not continue to supplant evidence-based clinical management.
