No effect of periodic continuous glucose monitoring on hemoglobin A1c in poorly regulated type 1 patients.
In a non-randomized study, patients with HbA1c >74 mmol/mol in three consecutive measurements were offered CGM for 6 days, then seen by a diabetologist and a diabetes nurse at start and again after 6 months. After 3 months, the patients were seen by a diabetes nurse and further offered to mail results of self-monitored blood glucose values (SMBG) for advice at 1.5 and 4.5 months. Patients who refused or were not offered CGM served as controls.
