NICE Recommends CGM for Diabetes in Pregnancy

Source: National Institute for Health and Care Excellence (NICE) Guideline – Diabetes in Pregnancy: Management from Preconception to the Postnatal Period (2020)

Key Takeaway: In December 2020, NICE reviewed the evidence and changed the recommendations on intermittently scanned CGM (isCGM, also commonly referred to as flash) and continuous glucose monitoring during pregnancy for women with type 1 diabetes.

Recommendations for Managing Diabetes During Pregnancy-Intermittently scanned CGM and continuous glucose monitoring

1.3.17	Offer continuous glucose monitoring (CGM) to all pregnant women with type 1 diabetes to help them meet their pregnancy blood glucose targets and improve neonatal outcomes.
1.3.18	Offer intermittently scanned CGM (isCGM, commonly referred to as flash) to pregnant women with type 1 diabetes who are unable to use continuous glucose monitoring or express a clear preference for it.
1.3.19	Consider continuous glucose monitoring for pregnant women who are on insulin therapy but do not have type 1 diabetes, if they have problematic severe hypoglycaemia (with or without impaired awareness of hypoglycaemia) or they have unstable blood glucose levels that are causing concern despite efforts to optimise glycaemic control.
1.3.20	For pregnant women who are using isCGM or continuous glucose monitoring, a member of the joint diabetes and antenatal care team with expertise in these systems should provide education and support (including advising women about sources of out-of-hours support).

For a short explanation of why the committee made the 2020 recommendations and how they might affect practice, see the rationale and impact section on flash and continuous glucose monitoring on pages 35-36 in the Guideline. Full details of the evidence and the committee’s discussion are in evidence review A: continuous glucose monitoring.
