Dexcom G6 Observational Study

Several studies have shown that the use of a device that can measure blood glucose levels
every 5 minutes is more effective in identifying low blood glucose (hypoglycemia) and high
blood glucose (hyperglycemia) when compared to regular measurements with fingersticks [point
of care (POC)].

This is an exploratory prospective study primary aiming to evaluate differences between
Point-of-care (POC) testing (standard of care) and Dexcom G6 CGM (Continues Glucose
Monitoring sensor system) in 1) glycemic control measured by mean daily blood glucose and 2)
identifying hypoglycemic and hyperglycemic events - in patients with type 1 and type 2
diabetes treated with basal bolus insulin regimen.

Inclusion Criteria:

1. > 18 years admitted to a general medicine or surgical service.

2. Known history of T1D or T2D receiving insulin therapy

3. Subjects must have a randomization BG between 140 mg and 400 mg/dL without laboratory
evidence of diabetic ketoacidosis (bicarbonate < 18 mEq/L, pH < 7.30, or positive
serum or urinary ketones).

4. Patients with expected hospital length-of-stay of 3 or more days

Exclusion Criteria:

1. Patients with acute illness admitted to the ICU or expected to require admission to
the ICU.

2. Patients expected to require MRI procedures during hospitalization.

3. Mental condition rendering the subject unable to understand the nature, scope, and
possible consequences of the study.

4. Female subjects who are pregnant or breast‑feeding at time of enrollment into the
study.
