Improved Biomedical and Psychological Outcomes 1 Year After Structured Education in Flexible Insulin Therapy for People With Type 1 Diabetes The U.K. DAFNE experience

OBJECTIVE-DAFNE (Dose Adjustment For Normal Eating), a structured education program in flexible insulin therapy, has been widely adopted in the U.K. after validation in a randomized trial. To determine benefits in routine practice, we collected biomedical and psychological data from all participants attending during a 12-month period. RESEARCH DESIGN AND METHODS-HbA(1c), weight, self-reported hypoglycemia awareness, severe hypoglycemia frequency, PAID (Problem Areas In Diabetes), HADS (Hospital Anxiety and Depression Scale), and EuroQol Group 5-Dimension Self-Report Questionnaire scores were recorded prior to DAFNE and after 1 year. RESULTS-Complete baseline and follow-up HbA(1c) data were available for 639 (54.9%) of 1,1.63 attendees. HbA(1c) fell from 8.51 +/- 1.41 (mean +/- SD) to 8.24 +/- 1.29% (difference 0.27 [95% CI 0.16-0.38]; P < 0.001), with a greater mean fall of 0.44% from baseline HbA(1c) >8.5%. Severe hypoglycemia rate fell from 1.7 +/- 8.5 to 0.6 +/- 3.7 episodes per person per year (1.1 [0.7-1.4]) and hypoglycemia recognition improved in 43% of those reporting unawareness. Baseline psychological distress was evident, with a PAID score of 25.2 and HADS scores of 5.3 (anxiety) and 4.8 (depression), falling to 16.7 (8.5 [6.6-10.4]), 4.6 (0.7 [0.4-1.0]), and 4.2 (0.6 [0.3-0.8]), respectively (all P < 0.001 at 1 year). Clinically relevant anxiety and depression (HADS >= 8) fell from 24.4 to 18.0% and 20.9 to 15.5%, respectively. CONCLUTIONS-A structured education program delivered in routine clinical practice not only improves HbA(1c) while reducing severe hypoglycemia rate and restoring hypoglycemia awareness but also reduces psychological distress and improves perceived well-being.
