Usage of Continuous Glucose Monitoring System in Paediatric Patients with Type 1 Diabetes in Hong Kong

Abstract

Purpose: The aim of this study is to analyse the usage of Continuous Glucose Monitoring System (CGMS) among paediatric population with type 1 diabetes in Hong Kong. Methods: Data was retrieved from the Hong Kong Childhood Diabetes Registry. Paediatric patients with type 1 diabetes with active follow-up in Hospital Authority in 2018 were included. Results: Three hundred and sixty patients were included in the analysis. Only 38 patients (10.6%) were regular CGMS users. The mean HbA1c of regular users was significantly lower than that of the non-regular CGMS users (7.4±1.2% vs. 8.5±1.9%; P=0.0003). The difference was still significant after adjusting for age, use of insulin pump and parents' occupations (P=0.038). The regular usage of CGMS was associated with younger age, use of insulin pump and higher socioeconomic position. Conclusions: The overall usage of CGMS among paediatric patients with type 1 diabetes in Hong Kong was relatively low.
