Continuous glucose monitoring
1.6.17 Offer intermittently scanned continuous glucose monitoring (isCGM, commonly
referred to as 'flash') to adults with type 2 diabetes on multiple daily insulin
injections if any of the following apply:
• they have recurrent hypoglycaemia or severe hypoglycaemia
• they have impaired hypoglycaemia awareness
• they have 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 but could use an isCGM device (or have it
scanned for them)
• they would otherwise be advised to self-measure at least 8 times a day.
