Assessment of barriers to improve diabetes management in older adults: a randomized controlled study.

OBJECTIVE: To evaluate whether assessment of barriers to self-care and strategies to cope with these barriers in older adults with diabetes is superior to usual care with attention control. The American Diabetes Association guidelines recommend the assessment of age-specific barriers. However, the effect of such strategy on outcomes is unknown. RESEARCH DESIGN AND METHODS: We randomized 100 subjects aged ≥69 years with poorly controlled diabetes (A1C >8%) in two groups. A geriatric diabetes team assessed barriers and developed strategies to help patients cope with barriers for an intervention group. The control group received equal amounts of attention time. The active intervention was performed for the first 6 months, followed by a "no-contact" period. Outcome measures included A1C, Tinetti test, 6-min walk test (6MWT), self-care frequency, and diabetes-related distress. RESULTS: We assessed 100 patients (age 75 ± 5 years, duration 21 ± 13 years, 68% type 2 diabetes, 89% on insulin) over 12 months. After the active period, A1C decreased by -0.45% in the intervention group vs. -0.31% in the control group. At 12 months, A1C decreased further in the intervention group by -0.21% vs. 0% in control group (linear mixed-model, P < 0.03). The intervention group showed additional benefits in scores on measures of self-care (Self-Care Inventory-R), gait and balance (Tinetti), and endurance (6MWT) compared with the control group. Diabetes-related distress improved in both groups. CONCLUSIONS: Only attention between clinic visits lowers diabetes-related distress in older adults. However, communication with an educator cognizant of patients' barriers improves glycemic control and self-care frequency, maintains functionality, and lowers distress in this population.

Frequent hypoglycemia among elderly patients with poor glycemic control.

BACKGROUND: Episodes of hypoglycemia are particularly dangerous in the older population. To reduce the risk of hypoglycemia, relaxation of the standard hemoglobin A(1c) (HbA(1c)) goals has been proposed for frail elderly patients. However, the risk of hypoglycemia in this population with higher HbA(1c) levels is unknown. METHODS: Patients 69 years or older with HbA(1C) values of 8% or greater were evaluated with blinded continuous glucose monitoring for 3 days. RESULTS: Forty adults (mean [SD] age, 75 [5] years; HbA(1C) value, 9.3% [1.3%]; diabetes duration, 22 [14] years; 28 patients [70%] with type 2 diabetes mellitus; and 37 [93%] using insulin) were evaluated. Twenty-six patients (65%) experienced 1 or more episodes of hypoglycemia (glucose level <70 mg/dL). Among these, 12 (46%) experienced a glucose level below 50 mg/dL and 19 (73%), a level below 60 mg/dL. The average number of episodes was 4; average duration, 46 minutes. Eighteen patients (69%) had at least 1 nocturnal episode (10 pm to 6 am). Of the total of 102 hypoglycemic episodes, 95 (93%) were unrecognized by finger-stick glucose measurements performed 4 times a day or by symptoms. CONCLUSIONS: Hypoglycemic episodes are common in older adults with poor glycemic control. Raising HbA(1C) goals may not be adequate to prevent hypoglycemia in this population.

Interpreting the Joslin Diabetes Center and Joslin Clinic Clinical Nutrition Guideline for Overweight and Obese Adults With Type 2 Diabetes.

Interpreting the Joslin Diabetes Center and Joslin Clinic Clinical Nutrition Guideline for Overweight and Obese Adults with Type 2 Diabetes, Prediabetes, or at High Risk for Developing Type 2 Diabetes is a weight loss approach to assist health care providers in a clinical setting when counseling overweight individuals. It recommends an individualized weight reduction plan consisting of a lower carbohydrate, moderate protein, and fat diet, with specific activity and behavior modification guidelines.
