Transition of Youth With Type 2 Diabetes: Predictors of Health-Care Utilization After Transition to Adult Care From Population-Based Administrative Data.

Objectives: In this study, we aimed to compare health-care visits pre- and posttransition from pediatric to adult care between youth with type 2 and type 1 diabetes.

Methods: We linked a clinical database with the Manitoba Population Research Data Repository to compare health-care visits 2 years before and after transition, and investigated baseline factors influencing health-care engagement.

Results: Youth with type 2 diabetes (n=196) vs type 1 diabetes (n=456) were more likely to be female (61% vs 44%), older at diagnosis (13.6 vs 10.6 years), live in northern regions and to be in the lowest socioeconomic status quartile (53% vs 5.4%). Seventy-six percent of youth with type 2 diabetes attended a follow-up visit within 2 years of transition compared to 97% of youth with type 1 diabetes. Youth with type 2 diabetes had higher rates of hospitalization pretransition (19.6 vs 11.6 admissions/100 patient years) and posttransition (24.7 vs 11.7 admissions/100 patient years) and fewer medical visits (pretransition: 2.4 vs 3.0 visits/person year [p<0.01]; posttransition: 1.6 vs 2.1 visits/person year [p<0.01]). Accounting for sex, geography, age, education, socioeconomic status and diabetes type, achieving 4 visits in 2 years posttransition was predicted by the number of visits pretransition (odds ratio, 1.35; 95% confidence interval, 1.23 to 1.49) and diabetes type (type 2 diabetes: odds ratio, 0.57; 95% confidence interval, 0.34 to 0.98).

Conclusions: Youth with type 2 diabetes attend fewer medical follow-up visits pre- and posttransition to adult care compared to youth with type 1 diabetes. Focused, informed, specific transition planning is needed that addresses the unique characteristics of this population.
