Should all patients on insulin be using continuous glucose monitoring?

Abstract

Continuous glucose monitoring (CGM) is being used increasingly both in patients on insulin pumps (CSII) and more recently in those on multiple injection regimens (MIR). This review lists the CGM devices available in South Africa and explores the literature supporting the use of CGM as a primary modality for monitoring blood glucose in those with diabetes on MIR. In particular, the role of CGM as a modality for improving glycaemic control and reducing hypoglycaemia is explored. The identification of appropriate patients, the possible barriers to the institution of CGM and the role of CGM in the future of diabetes care is discussed.
