Abstract
OBJECTIVE The potential benefits of continuous glucose monitoring (CGM) in the management of adults and children with well-controlled
type 1 diabetes have not been examined.
RESEARCH DESIGN AND METHODS A total of 129 adults and children with intensively treated type 1 diabetes (age range 8–69 years) and A1C <7.0% were randomly
assigned to either continuous or standard glucose monitoring for 26 weeks. The main study outcomes were time with glucose
level ≤70 mg/dl, A1C level, and severe hypoglycemic events.
RESULTS At 26 weeks, biochemical hypoglycemia (≤70 mg/dl) was less frequent in the CGM group than in the control group (median 54
vs. 91 min/day), but the difference was not statistically significant ( P = 0.16). Median time with a glucose level ≤60 mg/dl was 18 versus 35 min/day, respectively ( P = 0.05). Time out of range (≤70 or >180 mg/dl) was significantly lower in the CGM group than in the control group (377 vs.
491 min/day, P = 0.003). There was a significant treatment group difference favoring the CGM group in mean A1C at 26 weeks adjusted for
baseline ( P < 0.001). One or more severe hypoglycemic events occurred in 10 and 11% of the two groups, respectively ( P = 1.0). Four outcome measures combining A1C and hypoglycemia data favored the CGM group in comparison with the control group
( P < 0.001, 0.007, 0.005, and 0.003).
CONCLUSIONS Most outcomes, including those combining A1C and hypoglycemia, favored the CGM group. The weight of evidence suggests that
CGM is beneficial for individuals with type 1 diabetes who have already achieved excellent control with A1C <7.0%.
