Eligibility Criteria for NHS funding for those with Type 1 Diabetes (you need one of the following):
Monitoring > 8 times daily, as demonstrated on a meter download/review over the past 3 months
Those unable to routinely self-monitor blood glucose due to disability who require carers to support glucose monitoring and insulin management
Those with occupational (e.g. working in insufficiently hygienic conditions to safely facilitate finger-prick testing) or psychological circumstances that warrant a 6-month trial of Libre with appropriate adjunct support
Previous self-funders who would have satisfied one or more of these criteria prior to them commencing use of Flash Glucose Monitoring had these criteria been in place prior to April 2019 AND has shown improvement in HbA1c since self-funding
Can be considered as an alternative to CGM (severe hypoglycaemia or impaired awareness of hypoglycaemia, although NICE suggests that Continuous Glucose Monitoring with an alarm is the standard)
