Study summary

The primary objective of the CORDIA study is to use an effective evidence-based self-management intervention (SMI) for type 2 diabetes, with and without a novel test to give a personalised genetic and lifestyle risk of coronary heart disease, to examine their capacity to reduce the risk of coronary heart disease (CHD) and improve diabetes management in primary care patients with type 2 diabetes. The effect of these interventions on clinical, behavioural and psychological outcomes will be investigated.

Study arms

  • No intervention
    Usual Care

    The participant's General practitioner (GP) practice and/or practice nurse will provide care as normal for their patient.

  • Active comparator
    Group Self-Management Intervention (SMI)

    Participants will be asked to attend a total of 4 SMI sessions delivered on a weekly basis.

    Behavioral: Self-Management Intervention

  • Active comparator
    SMI + Risk Results

    The participant will provide a saliva sample for analysis. They will attend an appointment with their nurse to receive personalised results on their combined genetic and lifestyle risk for developing CHD in the next 10 years. They will then be asked to attend the 4 week SMI programme.

    Behavioral: Self-Management Intervention · Behavioral: Risk Result

Interventions

  • BehavioralSelf-Management Intervention

    The SMI will incorporate a discussion to introduce self-management and why it is important, and about problems associated with reducing CHD risk and managing type 2 diabetes. Specific topics addressed will include health behaviours to reduce CHD risk and manage diabetes including diet and exercise, as well as behaviours specific to managing diabetes, including medication adherence and self-care behaviours (e.g. footcare). Sessions are patient-directed and employ a shared decision-making approach, such that participants work with one another and the practice nurse facilitator to identify specific problems that they wish to address, and to identify solutions and approaches to managing their diabetes and CHD risk

  • BehavioralRisk Result

    Participants will receive in-person personalised feedback about their combined genetic and lifestyle 10 year risk for developing CHD.

What researchers measure

Primary outcomes

  1. Coronary heart disease 10 year risk

    Coronary heart disease 10 year risk as assessed using the United Kingdon Prospective Diabetes Study (UKPDS) Risk Calculator

    Time frame: 12 months

Secondary outcomes

  1. Psycho-social impact of the intervention

    Psycho-social impact of the intervention conditions will be assessed using questionnaires designed to measure risk perception, self-efficacy, and motivation. Feelings of anxiety and depression will also be assessed.

    Time frame: 12 months

  2. Health behaviour impact of the intervention

    The impact of the intervention conditions on health behaviours including diet, exercise and smoking behaviour will be assessed in addition to a range of diabetes self-care behaviours such as foot care and blood glucose self-monitoring.

    Time frame: 12 months

  3. Impact of receiving genetic results

    The impact of receiving genetic test results using a modified version of the Multidimensional Impact of Cancer Risk Assessment (MICRA) questionnaire.

    Time frame: 6 months
