Support-t Online Training in Youth Living With Type 1 Diabetes Transitioning to Adult Care

Study Overview
=================
Brief Summary
-----------------
The investigators will conduct a randomized controlled trial (RCT) to examine how an online training and peer support platform could help the preparation to transition to adult care. Among 14-16 year old youth with Type 1 Diabetes (T1D), the investigators aim to assess the effect of an online training and peer support platform (Support-t) integrated in usual care, compared with usual care on Hemoglobin A1c (HbA1c), adverse outcomes and psychosocial measures during the preparation for transition to adult care. The investigators will conduct a multi-site, parallel group, blinded (outcome assessors, data analysts), superiority RCT of adolescents with T1D (14-16 years of age) followed at one of 4 university teaching hospital-based pediatric diabetes clinics in the province of Quebec.

Detailed Description
-----------------
The transition from pediatric to adult diabetes care is a challenging period for adolescents and young adults living with chronic conditions, such as Type 1 Diabetes (T1D). For youth with T1D, transition from pediatric to adult care is characterized by deterioration in glycemic control (Hemoglobin A1c [HbA1c]), reduced adherence to diabetes management tasks and increased risk of diabetes complications. The investigators propose to examine an online training and peer support platform as a potential alternative for delivering transition care. In adolescents with T1D, the investigators hypothesize that an online training and peer support platform (Support-t), when integrated into usual pediatric care, as compared with usual care alone, will result in better HbA1c, less adverse outcomes and better psychosocial outcomes during the preparation for transfer to adult care. Primary Aim: To determine the impact of adding access to Support-t to usual care compared with usual care alone, on HbA1c during the preparation for transfer to adult care. Secondary Aims: To determine the impact of adding access to Support-t to usual care compared with usual care alone, on self-efficacy, diabetes distress, quality of life (QOL; diabetes specific), readiness to transfer to adult care, glucose management, severe hypoglycemic episodes, diabetic ketoacidosis (DKA), T1D-related ED-visits and hospitalizations during the preparation for transfer to adult care. 2. To determine the cost-effectiveness of Support-t. 3. To understand the context for implementation in regards to level of engagement on Support-t, satisfaction and experience (barriers, facilitators) with Support-t. Methods: The investigators will conduct a multi-site, parallel group, blinded (outcome assessors, data analysts), superiority RCT of adolescents with T1D (14-16 years of age) followed at one of 4 university teaching hospital-based pediatric diabetes clinics in Quebec. Patients will be recruited over 20 months. Interventions will occur over 18 months. Follow-up will be to 18 months from enrollment. Allocation will be concealed with a 1:1 intervention to control ratio. Participants in the active arm will have access to a mobile-based online training and peer support platform (Support-t) added to usual care. Participants in the control group will have in parallel with the intervention group, their usual diabetes care. The primary outcome is the change in HbA1c measured at 18 months (HbA1c measured at 18 months - HbA1c measured at baseline). Secondary outcomes are self-efficacy, diabetes distress, QOL, readiness to transfer, glucose management, severe hypoglycemic episodes, DKA, T1D-related ED-visits and hospitalizations. Assessments are at baseline, 6, 12 and 18 months. Analysis will be by intention-to-treat. Outcomes will be calculated and compared between the 2 trial arms using differences with 95% Confidence Intervals, along with a cost-effectiveness analysis. Interviews will be conducted to analyze the context for implementation.

Design Details

Primary Purpose: Supportive Care
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Active arm: Participants randomized to the active arm will have access to the Support-t online training and peer support platform in addition to their usual diabetes care, over the 18 month intervention period. Support-t contains 3 components: 1) Educational material, 2) News blog and 3) Patients' discussion forum. Control arm: Participants randomized to usual care only will attend their usual diabetes clinic visits, over the 18-month intervention period, which consists of visits with their health care provider and ad-hoc diabetes education with nurses and dietitians.
Masking: Single

Support-t contains 3 components: 1) Educational material, 2) News blog and 3) Patients' discussion forum. Health care providers from the pediatric diabetes clinics will receive Support-t training and will be encouraged to recommend the Support-t platform during routine care with their patients from the active arm. | Other: Support-t<br>* Support-t plus usual diabetes care for 18 months<br>|
| No Intervention: Usual diabetes care only<br>Usual diabetes care for 18 months, which consists of visits with their health care provider and ad-hoc diabetes education with nurses and dietitians. Health care providers from the pediatric diabetes clinics will be instructed not to discuss or refer to the Support-t platform with patients from the control arm. Control arm participants will have the option to use the Support-t platform after the 18-month study. | |

| Self-efficacy | Self-efficacy for Diabetes Self-Management Measure (SEDM) assesses self-efficacy. The score ranges from 1 to 10. All item scores are averaged to compute the score. A higher score represents a better outcome. | 0, 6, 12, 18 months | 
| Diabetes distress | Problem Areas in Diabetes Scale-Teen (PAID-T) assesses adolescent diabetes distress. The scores range from 14 to 84. A total distress score is computed by summing responses.
