Should All Pregnant Women with Type 1 Diabetes Have Continuous Glucose Monitoring?

The CONCEPTT study, published in the Lancet in September, studied pregnant women with type 1 diabetes who underwent randomization to either continuous glucose monitoring (CGM) or to usual monitoring. Both groups' mean levels of glycated hemoglobin were roughly the same after months of monitoring. However, the big benefit was to the neonates, who were significantly less likely to be born large-for-gestational-age or to be admitted to a neonatal ICU for more than 24 hours. Back-of-the-envelope calculations reveal that it makes economic sense to have all such pregnancies use CGM. Does it make clinical sense? Will patients put up with the inconvenience? We'll discuss.
