Implications for practice and research

  • Continuous glucose monitoring (CGM) devices are not inferior to point-of-care capillary glucose testing for inpatient glycaemic monitoring.

  • CGM devices could potentially reduce hypoglycaemic events in hospital, but require more research and training for acceptability in use.


Diabetes is a common metabolic disorder, present in more than 451 million people worldwide.1 The established practice for inpatient glycaemic monitoring when an individual whose diabetes is treated with basal-bolus insulin therapy is admitted to hospital is to use daily multiple bedside point-of-care (POC) capillary glucose testing. Guidelines recommend that POC testing …
