NHS England Criteria for access to continuous glucose monitoring

Criteria for access to continuous glucose monitoring:

NICE Guidelines (Updated March 2022)

Type 1 diabetes

• All adults with Type 1 diabetes should be offered real-time continuous glucose monitoring (rtCGM) or intermittently scanned continuous glucose monitoring (isCGM, commonly referred to as 'flash')

• All children with Type 1 diabetes should be offered real-time continuous glucose monitoring (rtCGM). If unable to use rtCGM or a clear preference is expressed for isCGM, they should be offered intermittently scanned continuous glucose monitoring ( commonly referred to as 'flash').

Type 2 diabetes

• Intermittently scanned continuous glucose monitoring (isCGM, commonly referred to as 'flash') can be offered to adults with type 2 diabetes on multiple daily insulin injections if any of the following apply:

  • recurrent hypoglycaemia or severe hypoglycaemia
  • impaired hypoglycaemia awareness
  • a condition or disability (including a learning disability or cognitive impairment) that means they cannot self-monitor their blood glucose by capillary blood glucose monitoring (finger prick testing) but could use an isCGM device (or have it scanned for them)
  • would otherwise need help from a care worker or healthcare professional to monitor their blood glucose
  • self-monitoring blood glucose at least 8 times a day.

During pregnancy

• Type 1 Diabetes and pregnant – real-time continuous glucose monitoring (rtCGM) should be offered. Intermittently scanned continuous glucose monitoring (isCGM, commonly referred to as 'flash') should be offered if unable to use rtCGM or a clear preference is expressed for isCGM.

• Type 2 Diabetes on insulin and pregnant - real-time continuous glucose monitoring (rtCGM) will be considered if any of the following apply:

  • problematic severe hypoglycaemia (with or without impaired awareness of hypoglycaemia)
  • unstable blood glucose levels despite efforts to control glucose levels
