Don’t routinely recommend daily home glucose monitoring for patients who have type 2 diabetes mellitus and are not using insulin.
|Rationale and Comments:||Self-monitoring of blood glucose is an integral part of patient self-management in maintaining safe and target-driven glucose control in type 1 diabetes mellitus. However, daily finger glucose testing has no benefit in patients with type 2 diabetes mellitus who are not on insulin or medications associated with hypoglycemia, and small, but significant, patient harms are associated with daily glucose testing. Self-monitoring of blood glucose should be reserved for patients during the titration of their medication doses or during periods of changes in patients’ diet and exercise routines.|
