Plain English Summary
Background and study aims
Developing type 2 diabetes is associated with obesity and inactivity, particularly in people who are diagnosed with impaired glucose regulation (IGR), a condition where blood glucose levels are raised above normal but not high enough to warrant a diagnosis of type 2 diabetes. Changes to lifestyle can delay diabetes onset, but achieving effective lifestyle change is difficult. Health coaching might be a flexible and effective way to do this. Health coaching involves a regular series of phone calls between patient and health professional to provide support and encouragement to the patient, and promote healthy behaviours such as healthy diet, physical activity and mobility, rehabilitation, and good mental health. Salford's multidisciplinary diabetes team delivers health coaching (known as Care Call) for people with type 2 diabetes, using health advisors. The service has been adapted to meet the needs of patients with IGR and show promising results. Salford offers an existing telephone only heath coaching service. There is also an enhanced version that makes greater use of web based materials which offers telephone plus web health coaching. This involves a series of short (20 minute) phone calls to patients, once a month over 6 months, with a step down call at 9 months. Patients are able to track progress using a web ‘dashboard’, and communicate with their health coach via the web interface. The aim of the study is to compare the existing telephone only service with the telephone plus web service.
Who can participate?
Adults diagnosed with IGR, referred to the Salford Care Call service (UK), who have access to a phone and home internet.
What does the study involve?
Participants will be randomly allocated to either the telephone only or telephone plus web health coaching service. Participants will be asked to fill in questionnaires about their condition and the service they receive.
What are the possible benefits and risks of participating?
We are not aware of any side effects, disadvantages or risks to you of taking part in this research. We do not know of any clinical benefits from taking part. However the information you provide during the course of this study will help us to better understand which health coaching service is preferred by patients and which health coaching service to commission in the future.
Where is the study run from?
The remote health coaching service will be delivered by health trainers from the Salford Diabetes Care Call service (UK).
When is the study starting and how long is it expected to run for?
November 2014 to August 2016
Who is funding the study?
Who is the main contact?

Comparison of active treatments for impaired glucose regulation: a Salford Royal Foundation Trust and Hitachi collaboration: a randomised controlled trial
Impaired Glucose Regulation (IGR) is the name given to two conditions which can occur called Impaired Glucose Tolerance (IGT) and Impaired Fasting Glycaemia (IFG) where glucose (sugar) is not being processed efficiently in the body. This results in blood glucose levels which are above the normal range. IGR is a form of prediabetes and if no action is taken around half of patients with IGR will go on to develop type 2 diabetes within 5 to 10 years, putting them at increased risk of further health problems. Relatively modest changes to lifestyle factors such as diet and activity can delay the onset of diabetes, and lifestyle change is recommended by the National Institute for Health and Care Excellence (NICE) as critical for effective prevention.
A model of care that has potential to achieve prevention through effective behaviour change is ‘health coaching’. The increasing adoption of telephone and mobile technologies among patients, and the potential to deliver care in ways that are efficient and flexible, has led to significant interest in the potential of health coaching. However evidence of effectiveness and acceptability is mixed.
This study aims to test acceptability and efficiency of two forms of remote health coaching for people with IGR. The principal questions this study asks are:
1. In adult patients with IGR, is a web based telephone coaching intervention more acceptable than an existing telephone only coaching intervention?
2. Is the delivery of the web based intervention more efficient in terms of direct health costs attributed to delivery than the existing teleohone only service?
3. Do patients randomised to the web based service have broadly equivalent clinical outcomes to patients randomised to the existing telephone only service?
