Acceptability of and satisfaction with continuous glucose monitoring in pregnant women with type 2 diabetes mellitus: A service improvement project

Abstract

Background There are limited data regarding intermittently scanned continuous glucose monitoring (isCGM) in pregnancy for women with Type 2 diabetes. We have tested the acceptability and feasibility of an isCGM method using Libre device. Method In a hospital-based service improvement project, 23 pregnant women (March 2022-April 2023), with Type 2 diabetes got isCGM for monitoring from 20 weeks until delivery. Women completed a structured and validated questionnaire assessing satisfaction, equipment issue, relationship with diabetes team. Results Two-thirds of the women were satisfied with the convenience and found it reliable. 86% wanted to use it for future pregnancies, and 90% would recommend it to others. Sensor falls off was seen in three obese women and about a tenth felt the reliability was poor in extreme ranges of sugar levels. The relationship with the diabetes team was rated high. Conclusion isCGM could be a useful and well-received tool for improving glycaemic control in pregnancies with Type 2 diabetes.
