The Efficacy and Acceptability of Flash Glucose Monitoring in Pregnant Women with Gestational Diabetes Mellitus: A Systematic Review.

Gestational diabetes mellitus (GDM) occurs in approximately 9% of pregnancies, and proper glycemic control is of utmost importance in the prevention of GDM-associated obstetric complications. Flash glucose monitoring (FGM), a subtype of continuous glucose monitoring (CGM), offers intermittent blood glucose scanning and is considered a propitious alternative to the standard method of self-monitoring of blood glucose (SMBG). The aim of this review was to systematically assess the efficacy and acceptability of FGM in in pregnancies complicated by GDM. A systematic literature search was performed in the PubMed, MEDLINE, Scopus, and Cochrane databases. The review was conducted following the PRISMA guidelines, and the study protocol has been registered in the PROSPERO database with the registration number CRD42024545874. A total of 872 articles were initially identified, 141 publications underwent an in-depth full-text analysis, resulting in 133 studies being excluded from further assessment. Eventually, eight studies were included in the analysis. The analysis revealed that FGM is a safe and efficient method of glycemic control in GDM. The majority of the studies consider its accuracy comparable to SMBG. Furthermore, FGM is well accepted by patients with numerous advantages in user-friendliness over SMBG.
