Time in Glucose Hospital Target

Краткое описание

Inpatient management of glycemia in people with diabetes has been inadequately studied. Previous randomized trials of intensive insulin therapy in the hospital setting resulted in excessive hypoglycemia. Current ADA guidelines (glucose 140-180 mg/dL) are by consensus with the upper bound defined by observational data and the lower bound by safety concerns. None of the previous studies of intensive glucose management used CGM technology. Whether near normal glucose levels can be achieved without increasing hypoglycemia among hospitalized patients with diabetes with the advent of CGM technology is not known. There are clear associations between hyperglycemia and poor outcomes in patients with diabetes hospitalized with infection, including COVID-19. The COVID-19 pandemic has increased the urgency to definitively answer the question of whether glucose lowering below 140-180 mg/dL can be achieved without increasing hypoglycemia. If this proposed study demonstrates intensive management of glucose to a target of 90 to 130 mg/dL without hypoglycemia is achievable in the inpatient setting with CGM technology, a larger study could then be performed to evaluate whether there is clinical benefit including a reduction in morbidity and mortality. The primary study hypothesis is that glucose management with CGM can achieve a mean glucose of 90-130 mg/dL without increasing hypoglycemia compared with standard care with a glucose target of 140-180 mg/dL. Individuals with diabetes who are hospitalized (non-ICU) for an eligible condition will be randomly assigned to receive standard therapy (glucose target 140-180 mg/dL per ADA guidelines) or intensive therapy (glucose target 90-130 mg/dL and CGM used for monitoring). Real-time CGM will be used in the Intensive Target Group and masked CGM will be used in the Standard Target Group. The co-primary outcomes, assessed via a hierarchical approach, include a treatment group comparison of mean glucose (superiority) followed by a non-inferiority comparison of time \<54 mg/dL measured with CGM.
