Abstract
Objective: Survey the bedtime glycemia in type 2 diabetic patients using insulin therapy. Patients and Methods: This prospective study included 57 consecutive diabetics who were admitted in the period January 2019 to January 2020 the Endocrine-General Internal Medicine Department, Hue University of Medicine and Pharmacy Hospital had 190 blood glucose monitoring times. Results: In group of patients over 65 years of age, mean prandial fast-acting insulin dose for dinner was 8.84 ± 2.56 IU; mean long-acting insulin dose was 11.90 ± 4.28 IU; mean afternoon mixed insulin dose was 8.20 ± 2.05 IU. Mean bedtime glycemia in group of patients over 65 years of age and all patients was 15.24 ± 6.43 and 16.74 ± 7.25, respectively. The group of patients with mild combination disease and dementia did not achieve the treatment goals. 31.3% of group with many combination diseases, severe cardiovascular disease, and severe dementia (group 3) achieved goals of treatment while 43.7% of patients did not. Regarding control bedtime glycemia in patients over 65 years of age, 16.1% of patients in group 3 achieved treatment goals; 35.5% did not; especially 12.9% of cases having nocturnal hypoglycemia. Conclusions: The demand of insulin for type 2 diabetics is huge for achieving treatment goals. The nocturnal hypoglycemia are always a risk for diabetics over 65 years old. This poses the strong recommendation for bedtime blood glucose monitoring for elderly diabetics.
