Results From a Randomized Trial of Intensive Glucose Management Using CGM Versus Usual Care in Hospitalized Adults With Type 2 Diabetes: The TIGHT Study.

Objective: To evaluate whether continuous glucose monitoring (CGM) could assist providers in intensifying glycemic management in hospitalized patients with type 2 diabetes.

Research Design And Methods: At six academic hospitals, adults with type 2 diabetes hospitalized in a non-intensive care setting were randomly assigned to either standard therapy with glucose target 140-180 mg/dL (standard group) or intensive therapy with glucose target 90-130 mg/dL guided by CGM (intensive group). The primary outcome was mean glucose measured with CGM (blinded in standard group), and the key secondary outcome was CGM glucose <54 mg/dL.
