This is a pilot study enrolling adult hemodialysis patients with diabetes recruited from the University of California Irvine Medical Center (UCIMC) who will undergo simultaneous measurement of glucose levels using 1) continuous glucose monitor (CGM) measured by a Dexcom G6 device vs. 2) "gold-standard" blood glucose levels using capillary fingerstick or venous blood glucose measurements obtained on a point of care (POC) blood glucose meter. The study will assess Dexcom G6 accuracy by comparing glucose levels on the CGM device vs. blood glucose measurements in the study population.

Inclusion Criteria:

• Adult hemodialysis patients age 18 years or older
• Have a comorbidity of diabetes
• Receipt of care from the inpatient University of California Irvine Medical Center nephrology consult service
• Expected hospital stay ≥48 hours
• Have the ability to directly provide informed consent for participation in the study

Exclusion Criteria:

• Critically-ill patients receiving care in the intensive care unit (ICU) or cardiac care unit (CCU)
• Moribund patients expected to die within 48 hours
• Presence of any condition deemed by PI's judgment that would seriously limit life expectancy (i.e., poor survival)
• Pregnant
• Unwilling or unable to provide informed consent
