6.1.8 Continuous glucose monitors (CGMs)

The routine commissioning of continuous glucose monitors (CGMs) is accepted in Devon for the patients with type 1 diabetes mellitus in line with specific criteria; CGMs are not routinely commissioned for use outside these patient groups. CGM requires specialist initiation with a review at 6 months and annually thereafter (refer to Commissioning Policy for initiation and continuation criteria).

Specialists must inform GPs when a patient is initiated on a CGM device, CGM sensors cannot be prescribed on FP10 and must be supplied by secondary care.

GPs should consider reducing the number of testing strips and lancets the patient requires in combination with a continuous glucose monitor.

Please refer to DVLA guidance regarding the use of interstitial glucose monitors when driving.
