Quality statement 4: Continuous glucose monitoring for adults who use insulin and need help monitoring their blood glucose

Quality statement

Adults with insulin-treated type 2 diabetes having their blood glucose monitored by a care worker or healthcare professional are offered continuous glucose monitoring (CGM). [new 2023]

Rationale

CGM can help to improve glycaemic control in adults with type 2 diabetes who use insulin. It helps to improve glycaemic control by providing sufficient, reliable recordings of glucose against which insulin dose and schedules can be adjusted. The use of CGM by adults with type 2 diabetes who need help to monitor their blood glucose and administer insulin injections will help care workers to record blood glucose levels quickly. For people who have multiple visits per day, blood glucose levels can be recorded at each visit. This can be used to adjust their insulin levels to reduce the risk of hypoglycaemic events between home visits and may also reduce the number of hospital admissions.

Quality measures

The following measures can be used to assess the quality of care or service provision specified in the statement. They are examples of how the statement can be measured, and can be adapted and used flexibly. The quality measures focus on use of CGM by adults who need help from a care worker or healthcare professional to monitor their blood glucose. The measures aim to reduce health inequalities in this group. Local services may want to identify other groups to focus measures on, for example, by reporting data for other groups that need help to monitor their blood glucose, by age or indices of deprivation.

Process

Proportion of adults with insulin-treated type 2 diabetes who need help from a care worker or healthcare professional to monitor their blood glucose who use CGM.

Numerator – the number in the denominator who use CGM.

Denominator – the number of adults with insulin-treated type 2 diabetes who need help from a care worker or healthcare professional to monitor their blood glucose.

Data source: No routinely collected national data for this measure has been identified. Data can be collected from information recorded locally by healthcare professionals and provider organisations, for example from patient records.

Outcome

HbA1c levels for adults with insulin-treated type 2 diabetes who need help from a care worker or healthcare professional to monitor their blood glucose.

Data source: No routinely collected national data for this measure has been identified. Data can be collected from information recorded locally by healthcare professionals, for example from patient records.

What the quality statement means for different audiences

Service providers (such as primary care networks, community providers and secondary care services) ensure that systems are in place to offer CGM to adults with insulin-treated type 2 diabetes who need help from a care worker or healthcare professional to monitor their blood glucose. They should ensure education is provided alongside CGM to support adults to use it. They should also address inequalities in CGM access and uptake by monitoring who is using CGM, identifying groups who are eligible but who have a lower uptake and making plans to engage with these groups to encourage them to consider CGM.

Healthcare professionals (such as GPS, diabetes specialist nurses and consultant diabetologists) are aware of CGM availability and offer it to adults with insulin-treated type 2 diabetes who need help from a care worker or healthcare professional to monitor their blood glucose. They also provide education to support them to use the CGM device and review their use as part of their diabetes care plan. In addition, they should help to address inequalities in CGM access and uptake by monitoring who is using CGM, identifying groups who are eligible but who have a lower uptake and making plans to engage with these groups to encourage them to consider CGM.

Integrated care systems ensure that services offer intermittently scanned CGM (isCGM), or real-time CGM (rtCGM) if it is available for the same or lower cost as isCGM, to adults with insulin-treated type 2 diabetes who would need help from a care worker or healthcare professional to monitor their blood glucose. They should also address inequalities in CGM access and uptake by commissioning services that monitor who is using CGM, identify groups who are eligible but who have a lower uptake and make plans to engage with these groups to encourage them to consider CGM.

Adults with insulin-treated type 2 diabetes who would need help to monitor their blood glucose are offered a CGM device to help them manage their diabetes. They and their care workers or healthcare professionals also receive education on how to use it. Their use of CGM is reviewed as part of their diabetes care plan.

Definitions of terms used in this quality statement

Continuous glucose monitoring

A CGM is a device that measures blood glucose levels and sends the readings to a display device or smartphone. rtCGM and isCGM, commonly referred to as 'flash', automatically measure glucose levels through a sensor applied under the skin. This allows patterns of glucose levels to be seen, which can be used to plan insulin treatment. rtCGM can be considered as an alternative to isCGM if it is available for the same or lower cost. [Adapted from NICE's guideline on type 2 diabetes in adults, recommendation 1.6.19, terms used in this guideline and expert opinion]

Equality and diversity considerations

Integrated care systems, providers and healthcare professionals should address inequalities in CGM access and uptake by monitoring who is using it, identifying groups who are eligible but have lower uptake and making plans to engage with these groups and encourage them to consider CGM, for example, older adults (aged 65 and over), adults with frailty and adults with physical, mental health related or learning disabilities. Data suggests that adults with diabetes from lower socioeconomic groups are less likely to access CGM.

Adults with type 2 diabetes who are offered CGM should be given information about using the technology that they can easily read and understand themselves, or with support, so they can communicate effectively with health and social care services. Information should be in a format that suits their needs and preferences. It should be accessible to adults who do not speak or read English, and it should be culturally appropriate and age appropriate. Adults should have access to an interpreter or advocate if needed.

For adults with additional needs related to a disability, impairment or sensory loss, information should be provided as set out in NHS England's Accessible Information Standard or the equivalent standards for the devolved nations.
