A psychoeducational program to restore hypoglycemia awareness: the DAFNE-HART pilot study.

OBJECTIVE

To develop and pilot a novel intervention addressing motivational and cognitive barriers to avoiding hypoglycemia in people with type 1 diabetes and persistent impaired awareness of hypoglycemia (IAH) despite training in flexible insulin therapy.

RESEARCH DESIGN AND METHODS

A 6-week intervention using motivational interviewing and cognitive behavioral techniques was designed. Diabetes educators were trained and supported in its delivery to 23 people with IAH (Gold score ≥4).

RESULTS

Twelve months postcourse, hypoglycemia awareness had improved (P < 0.001). Median (range) rates of severe hypoglycemia (SH) fell from 3 (0-104) to 0 (0-3) per person per year (P < 0.0001) and moderate from 14 (0-100) to 0 (0-18) per person per 6 weeks (P < 0.001). Worry and behavior around hyperglycemia improved. HbA1c was unchanged.

CONCLUSIONS

A pilot intervention targeting motivation and cognitions around hypoglycemia engaged patients with resistant IAH and recurrent SH and was associated with significant improvement, supporting the hypothesis that these factors underpin problematic hypoglycemia.
