BackgroundFailure to achieve treatment targets is common among people with type 2 diabetes. Cost-effective treatments are required to delay the onset and slow the progression of diabetes-related complications.AimsThis study aimed to measure the effect of a 6-month telephone coaching intervention on glycaemic control, risk factor status and adherence to diabetes management practices at the intervention's conclusion (6 months) and at 12 months.MethodThis randomised controlled trial recruited 94 adults with type 2 diabetes and an HbA1C > 7% from the Diabetes Clinic of St Vincent's Hospital Melbourne. People who were non-English speaking, cognitively impaired, severely hearing impaired or without telephone access were excluded. Participants were randomised to receive usual care plus 6 months of telephone coaching focusing on achieving treatment targets and complication screening, or usual care only. The primary outcome was HbA1C at 6 months; secondary outcomes included other physiological and monitoring measures.ResultsSignificant interaction effects were observed between group and time at 6 months, demonstrating improvement in HbA1C, fasting glucose, diastolic blood pressure and physical activity. The intervention's effect on these parameters was not sustained at 12 months. Intervention group participants also improved compliance with foot examinations and pneumococcal vaccination by 6 months and retinal screening by 12 months.ConclusionsTelephone coaching improved glycaemic control and adherence to complication screening in people with type 2 diabetes, for the duration of its delivery, but these effects were not maintained on withdrawal of the intervention. Strategies that assist patients to sustain these benefits are required.© 2014 The Authors; Internal Medicine Journal © 2014 Royal Australasian College of Physicians.
