Alternative approaches to glucose measurements during oral glucose tolerance testing in youth with cystic fibrosis: a mixed methods pilot study.

ABSTRACT:

Background

Adherence to annual OGTT screening for cystic fibrosis-related diabetes (CFRD) is poor. In this mixed methods study we assessed the accuracy, feasibility, and acceptability of alternative approaches to glucose measurements during an OGTT.

Methods

Standard OGTT with plasma glucose sampling at 0, 60, and 120-min was conducted in 14 youth ≥ 10 years of age with CF. A self-administered OGTT kit (Digostics, GTT@home) measuring capillary glucose and Dexcom G7 continuous glucose monitoring (CGM) were performed concomitantly with OGTT. CGM glucose values were recorded at 5-minute intervals for 20-minutes after each time point to account for lag. Plasma OGTT glucose and glucose tolerance categories [normal (NGT), impaired (IGT), indeterminate (INDET), and CFRD] were compar
