Randomized controlled feasibility trial of supported self-management in adults with Type 2 diabetes mellitus and an intellectual disability: OK Diabetes.

ABSTRACT: AIMS:To undertake a feasibility randomized controlled trial of supported self-management vs treatment as usual in a population of adults with obesity, Type 2 diabetes and an intellectual disability. METHODS:We conducted an individually randomized feasibility trial. Participants were adults aged >18 years with a mild or moderate intellectual disability, living in the community with Type 2 diabetes, on any therapy other than insulin. Participants had mental capacity to consent to research and the intervention. Inclusion criteria included HbA1c > 48 mmol/mol (6.5%), BMI >25 kg/m2 , or self-reported physical activity below national guideline levels. The experimental intervention was standardized supported self-management delivered by diabetes specialist nurses plus treatment as usual, compared with treatment as usual alone. Feasibility outcomes included: recruitment and retention; intervention acceptability and feasibility; data collection and completeness for physiological state and values for candidate primary outcomes (HbA1c and BMI). RESULTS:A total of 82 participants (89% of those contacted and eligible) were randomized. All supported self-management sessions were completed by 35/41 participants (85%); only four completed no sessions. Data on the follow-up candidate primary outcomes HbA1c and BMI were obtained for 75/82 (91%) and 77/82 participants (94%), respectively. The mean baseline HbA1c was 56±16.5 mmol/mol (7.3±1.5%) and the mean BMI was 34±7.6 kg/m2 . CONCLUSIONS:Adherence to supported self-management and willingness to have blood taken for outcome measurement was good. A definitive randomized controlled trial is feasible in this population.
