In this randomized clinical trial of hospitalized adults with diabetes, CGM threshold glucose alerts modestly improved glycemic control compared with CGM use without alerts. The addition of predictive alerts did not confer further glycemic benefit beyond threshold alerts alone. Future development of integrated clinical decision support systems or automated insulin delivery technologies may further enhance the effectiveness of CGM among hospitalized patients.
