Freestyle Libre Flash Glucose Monitoring System

(Licence No.: 99351)

The FreeStyle Libre Flash Glucose Monitoring System Reader (“Reader”)/FreeStyle LibreLink app (“App”) when used with a FreeStyle Libre Flash Glucose Monitoring System Sensor (“Sensor”) is indicated for measuring interstitial fluid glucose levels in adults aged 18 years and older (with or without diabetes) in all hospital and all professional healthcare settings including patients receiving medical intervention/therapy for COVID-19. In home setting, FreeStyle Libre system is indicated for measuring interstitial fluid glucose levels in adults aged 18 years and older with diabetes. The Reader/App and Sensor are designed to replace blood glucose testing in the self-management of diabetes, including dosing of insulin. Treatment decisions should not be based on realtime Sensor glucose readings alone and instead should consider all the information on the results screen

Safety and Effectivenes: Supported by a review of the published literature regarding the use of the system in hospitalized patients (both critically ill and non-critically ill populations), and sensory accuracy performance testing with risk assessment which provided assurance that the benefit of reduced patient contact and reduced usage of personal protective equipment outweighs the risks associated with potential suboptimal sensor accuracy in hospitalized patients.

Additional Warnings and Precautions:

Hospitals should consider whether they have the resources and expertise necessary to adequately implement Continuous Glucose Monitoring (CGM) system use in their facility and provide appropriate training to healthcare providers.

The FreeStyle Libre system is to be used in patients to perform glucose scans by themselves or with the aid of caregivers or healthcare professionals.

CGM glucose results are less accurate than blood glucose results obtained using traditional testing methods (e.g., lab glucose, blood glucose meters) in hospital settings. Users should consider all CGM glucose information (e.g., trend) along with individual glucose values, and interpret CGM results in the context of the full clinical picture.

CGMs may be subject to interferences that may generate falsely high and falsely low glucose readings. Levels of interference depend on drug concentration; substances that may not significantly interfere in non-hospitalized patients may interfere when used in the hospital setting because of higher dose levels. Most drugs used in hospital or critical care settings have not been evaluated and their interference with CGMs is unknown. Known interferences for FreeStyle Libre system include a positive bias due to high doses of ascorbic acid (Vitamin C) and a slight negative bias when taking salicylic acid (used in some pain relievers such as aspirin). Other reducing drugs / compounds may also interfere.

Dexcom G6 Continuous Glucose Monitoring System (Licence No.: 102449) The Dexcom G6 Continuous Glucose Monitor may be used in hospital to monitor critically ill patients.

Safety and Effectiveness:

It is hoped that the use of real time continuous glucose monitoring devices, such as the Dexcom CGM system, will help reduce personal protective equipment (PPE) usage and hospital staff exposure during the current COVID-19 pandemic.

Expanded use was supported by literature on the use of continuous glucose monitoring in hospitalized or critical care settings as well as recent article related to glycemic characteristics and clinical outcomes of COVID-19 patients Hospitalized in the United States.

Additional Warnings and Precautions:

Continuous glucose readings do have interpersonal variability and have not been tested on COVID-19 related patients.

Hospitals should continue to use their existing protocols to manage and treat patient glucose levels. Real time CGM can be used to provide remote monitoring and glucose trends to aid in glucose management and medical decision making.

CGM glucose results can be less accurate than blood glucose results obtained using traditional testing methods (e.g., lab glucose, blood glucose meters). Users should consider all CGM glucose information (e.g., trend) along with individual glucose values and interpret CGM results in the context of the full clinical picture.

CGMs may be subject to interferences that may generate falsely high and falsely low glucose readings. Levels of interference depend on drug concentration; substances that may not significantly interfere in non-hospitalized patients may interfere when used in the hospital setting because of higher dose levels. Most drugs used in hospital or critical care settings have not been evaluated and their interference with CGMs is unknown. Based on its structure, it is unlikely hydroxychloroquine would interfere with Dexcom CGM. Known interferences vary by CGM brand and can include:

  • Acetaminophen2
  • Ascorbic acid,
  • Hydroxyurea,
  • Other reducing drugs/ compounds.

Poor peripheral blood perfusion may cause inaccurate sensor readings. CGM results should be interpreted considering accompanying patient conditions and medications. Other clinical conditions may also cause inaccurate readings.

Dexcom G6 CGM System has not been tested in MRI/CT/Diathermy situations.

Remove CGM prior to MRI/CT/Diathermy tests. See, Dexcom’s “Using Your G6” guide for warnings and precautions.

Dexcom G6 Continous Glucose Monitoring System (Licence No.: 102449)

The Dexcom G6 Continuous Glucose Monitoring System may be used by pregnant women with diabetes mellitus as an adjunctive device to complement, not replace, information obtained from standard home glucose monitoring devices. Treatment decisions should be based on measurements obtained using a blood glucose meter as per standard of care self-monitoring of blood glucose.

In the general adult population, the Canadian Medical Device Licence for the Dexcom G6 Sensor labels it to be worn on the abdomen (belly). For pregnant women under this Interim Order Expanded Use, the Dexcom G6 Sensor is being authorized to be worn on the abdomen (belly) or back of the upper arm.

Patients are encouraged to speak to their care providers about using the remote glucose data sharing capabilities of the Dexcom G6 System, Dexcom Share App, and Dexcom CLARITY, to share their glucose data with their care providers in an effort to limit the necessity for direct contact between patients and their care providers during the pandemic.

The anticipated potential benefits of this expanded use during the pandemic, based on results of a clinical study of the Dexcom G6 System in pregnant women with diabetes mellitus, recommendations of Diabetes Canada and American Diabetes Association guidelines, and related clinical literature for use of continuous glucose monitoring in pregnant women are: reduced contact between patients and their care providers, thus limiting the potential spread of COVID-19, and; to help identify periods of hypoglycemia and hyperglycemia and help achieve glycemic targets.

The potential risks, based on the available information, are:

  • The effect of common medications on the Dexcom G6 glucose readings was assessed in relation to the general population and not specific to the pregnant population. Medications commonly prescribed during pregnancy may not been evaluated and their interference with the Dexcom G6 is therefore unknown;
  • With the Dexcom G6, you can take a standard or maximum acetaminophen dose of 1 gram (1,000mg) every 6 hours. Taking higher than the maximum dose of acetaminophen (e.g. > 1 gram every 6 hours in adults) may affect the G6 readings and make them look higher than they really are.
  • CGM readings can vary depending on the patient’s glucose levels. The Dexcom G6 clinical study in pregnant women included limited reference glucose measurements in both level 1 and level 2 hypoglycemia or hyperglycemia ranges. CGM readings are typically less accurate during the first day of sensor wear. The Dexcom G6 was not tested against reference glucose measurements on the first day of sensor wear in pregnant women.

Treatment decisions should be based on measurements obtained using a blood glucose meter as per standard of care self-monitoring of blood glucose.

Patients are encouraged to speak to their care providers about using the Carelink software to share their glucose data with their care providers in an effort to limit the necessity for direct contact between patients and their care providers during the pandemic.

The anticipated potential benefits of this expanded use during the pandemic, based on results of the CONCEPTT randomised controlled trial, recommendations of Diabetes Canada and American Diabetes Association guidelines, and related clinical literature for use of continuous glucose monitoring in pregnant women are: reduced contact between patients and their care providers, thus limiting the potential spread of COVID-19, and; to help identify periods of hypoglycemia and hyperglycemia and help achieve glycemic targets.

The potential risks, based on the available information, are:

  • Taking medications with acetaminophen while wearing the Enlite Sensor may falsely raise your sensor glucose readings. The level of inaccuracy depends on the amount of acetaminophen active in your body and may be different for each person.
  • The effect of common medications on the Enlite Sensor glucose readings was assessed in relation to the general population and not specific to the pregnant population. Medications commonly prescribed during pregnancy may not have been evaluated and their interference with the Enlite Sensor is therefore unknown;
  • To the best of Health Canada’s knowledge, the accuracy of the Enlite Sensor versus a blood glucose reference method has not been studied in pregnant women.
