Background and study aims
Studies of diabetes care in Ireland suggest that good blood sugar control is being achieved only by a minority of patients. Medical care for a person with type 1 diabetes is usually delivered in hospital outpatient clinics and frequently involves healthcare professionals telling patients how much to adjust their insulin doses. Patients frequently lack good self-management skills. The Dose Adjustment for Normal Eating (DAFNE) programme was developed in the UK and is delivered to groups of patients with type 1 diabetes. In an evaluation in the UK the programme led to a marked improvement in blood sugar control at 6 months but this improvement diminished considerably by 12 months, probably because patients were unable to maintain the skills that they acquired. This study aims to introduce a new model of group education after patients have completed the DAFNE programme, emphasising self-management. The study will compare this new model of group education support with traditional one-to-one clinic visits. The group support model will be based on peer support and expert patient input. This study has the potential to change the way that diabetes care is delivered and to introduce a new model of chronic disease management in Ireland.
Who can participate?
Patients who are already on waiting lists to complete a DAFNE course in Diabetes Centres in Ireland and Northern Ireland are able to take part. Patients must be over 18 years old, with type 1 diabetes and with a HbA1c of less than 13%.
What does the study involve?
Patients will be randomly allocated to receive either DAFNE and group support follow-up or DAFNE and one-to-one clinic visits. We will measure blood sugar control, frequency of hypoglycaemia (low blood sugar reactions), patient well-being and satisfaction with care (assessed using questionnaires). We will undertake in-depth interviews with some of the patients to explore how the programme influences a persons life with diabetes. We will do a health economic analysis to ensure that the extra cost of delivering DAFNE pays for itself in terms of improvement in health outcomes.
What are the possible benefits and risks of participating?
Studies have reported that patients usually enjoy being involved in research. People who take part will help to answer the important question of how best to support patients after they complete a structured education programme like DAFNE.
Where is the study run from?
The study will be run from the Diabetes Centre in University Hospital Galway (Ireland).
When is the study starting and how long is it expected to run for?
The study started in January 2007 and finished in September 2011.
Who is funding the study?
The Health Research Board (Ireland).

| Scientific title | Implementing and evaluating a structured education programme and a new model of ongoing care for type 1 diabetes: the Irish Dose Adjustment For Normal Eating (DAFNE) study - a randomised controlled trial |
| Study acronym | DAFNE Ireland |
| Study objectives | The long-term objectives of this work are to embed structured education for patients with type 1 diabetes in the Irish Health Service and to develop a more patient-centred approach to ongoing diabetes care. This will be accomplished through collaborative work within Ireland (North and South) and with centres in the UK experienced in delivering the DAFNE self-management education programme. These objectives will be accomplished through the following specific aims: 1. To develop a new model of ongoing care for DAFNE graduates based on group follow-up and peer support 2. To undertake an exploratory trial comparing this new model of care (group follow-up of DAFNE graduates) with usual care, i.e. a return to one-to-one clinic visits following DAFNE training 3. To incorporate a health economic analysis to inform future policy making 4. To undertake in-depth interviews on a subset of DAFNE graduates to explore their understanding and experiences of participating in DAFNE and to explore the factors that facilitate or hinder self-management following DAFNE training and how these might change over time and in light of receiving 'usual' versus group follow-up On 13/02/2009 the scientific title was added. Recruitment finished in December 2008. 450 participants have been enrolled to date and are through baseline. On 20/07/2010 the end date of this trial was extended from 31/12/2009 to 30/09/2011. |

| Intervention | After obtaining informed consent participants will be assigned to the next available DAFNE course in their participating centre. Prior to commencement of the course, baseline data will be collected. If a change to a basal/bolus insulin regimen is required this will be undertaken over the weekend prior to DAFNE training. Participants assigned to usual care will be offered appointments at a diabetes clinic at 6 and 12 months after DAFNE training. These visits will not be structured but efforts will be made to have patients seen by the educator(s) and doctor who participated in their DAFNE training. Those individuals assigned to the group follow-up arm of the study will receive their follow-up in the original group in which they underwent DAFNE training. Visits will be arranged as close as possible to 6 and 12 months after the course and will be facilitated by one of the group's original 2 DAFNE educators. The curriculum developed in the first phase of the project will be used during these sessions. An experienced DAFNE educator will combine delivery of a curriculum with a patient-centred approach to priority setting and problem solving. Each group follow-up session will last approximately 2 hours. Three self-administered questionnaires will be used to measure wellbeing and quality of life. These will be administered at baseline and again at 6, 12 and 18 months after recruitment. Forms will be completed in the diabetes centre as part of a visit to measure study outcomes. In a subset of participants an in-depth interview will be undertaken to explore the impact that DAFNE training has on the participants' ability to live with and self-manage their diabetes. In a subset of participants follow-up telephone interviews will be used to establish how the different models of follow-up care being delivered in the study impact on participants' ability to self-manage their diabetes.
