Closing the Gap: Results of the Multicenter Canadian Randomized Controlled Trial of Structured Transition in Young Adults With Type 1 Diabetes.

OBJECTIVE

To determine if a structured transition program for young adults with type 1 diabetes improves clinic attendance, glycemic control, diabetes-related distress, quality of life, and satisfaction with care.

RESEARCH DESIGN AND METHODS

In this multicenter randomized controlled trial, young adults (17-20 years) with type 1 diabetes were randomly assigned to a transition program with a transition coordinator or to standard care. The intervention lasted 18 months (6 in pediatric and 12 in adult care). The primary outcome was the proportion of participants who failed to attend at least one adult diabetes clinic visit during the 12-month follow-up after completion of the intervention.

RESULTS

We randomized 205 participants, 104 to the transition program and 101 to standard care. Clinic attendance was improved in the transition program (mean [SD] number of visits 4.1 [1.1] vs. 3.6 [1.2], = 0.002), and there was greater satisfaction with care (mean [SD] score 29.0 [2.7] vs. 27.9 [3.4], = 0.032) and less diabetes-related distress (mean [SD] score 1.9 [0.8] vs. 2.1 [0.8], = 0.049) reported than in standard care. There was a trend toward improvement in mean HbA (8.33% [68 mmol/mol] vs. 8.80% [73 mmol/mol], = 0.057). During the 12-month follow-up, there was no difference in those failing to attend at least one clinic visit ( = 0.846), and the mean change in HbA did not differ between the groups ( = 0.073). At completion of follow-up, the groups did not differ with respect to satisfaction with care or diabetes-related distress and quality of life.

CONCLUSIONS

Transition support during this 18-month intervention was associated with increased clinic attendance, improved satisfaction with care, and decreased diabetes-related distress, but these benefits were not sustained 12 months after completion of the intervention.
