A new approach to type 1 diabetes - Irish Study Update
Dr Seán Dinneen
SEP
“The aim of education for people with diabetes is to improve their knowledge and skills enabling them to take control of their own conditions and to integrate self-management into their daily lives”
NICE
The goals of education
Competence:
• what individuals know or are able to do in terms of knowledge, skills and attitudes
Capability:
• the extent to which individuals can adapt to change, generate new knowledge, and continue to improve their performance
Fraser, Greenhalgh. BMJ 2001;323:799
• Jean Phillipe Assal, Geneva; introduced the concept of TPE based (partly) on personal negative experiences
• Michael Berger (1944-2002), Dusseldorf; implemented the first structured education programme for patients with Type 1 diabetes
The “Founding Fathers” of TPE
Background
• 1970s: Self-management have been prominent elements of diabetes care in Germany
• Success prompted British Endocrinologists to trial a translated & modified version of the programme in the UK.
• Initial trial: ↓ in HbA1c levels without ↑ in hypoglycaemic episodes, ↑ patient satisfaction & QoL
• The number of DAFNE centres is ↑ every year. • The joint Diabetes UK / Department Health report on
Structured Patient Education in Diabetes (2005), stated that quality assurance (QA) is essential to ensuring the quality and validity of any diabetes education programme.
Irish DAFNE StudyHRB 2006• Aims: implementation &
evaluation of a SEP for people with T1D & to develop a new model of ongoing care based on peer-support and group follow-up
Sub-Studies• RCT of follow-up• Health Economics• Qualitative• Psychometric evaluation of
DSQOLS• Collaborations with DAFNE UK

UK DAFNE Study
Irish DAFNE Study
• Establishment of a DAFNE Steering Group that involves a multi-disciplinary team across Ireland of Physicians, Psychologists, Health Economists, DNS, Dietitians, Biostatisticians & DAFNE experts from the UK
• Into year 3 of 5 years of research – with our HRB Mid-term review due in May 09
• Galway is the lead coordinating centre for this 6 site RCT study
• Recent NIHR funding has been awarded to DAFNE Research Group in the UK – this will allow further comparability and collaboration between the 2 groups
Study to date
• Over 400 participants through baseline
• 72 courses have been delivered among the study’s 6 sites
• Qualitative Study will be completed in May 09
• Starting to disseminate our results via papers, abstracts and oral presentations
• HRB Mid-term review to be held in 21st May –focusing on our strategic plans for years 4 and 5
Feedback from Galway Graduate
“…something that really makes a huge difference to me and I can imagine that it would do the same for a lot of people -it also leads to less appointments in the centre, meaning better care for those who need it and, I am sure, economic savings, which is good at any time, but particularly in a time of recession (this also means less time taken off work for the DAFNE graduates).
Living in County Clare, I know that most people in the county with Type 1 Diabetes attend the Limerick Diabetes centre where the DAFNE program does not occur. I know now why I was recommended to Galway rather than Limerick when I moved to Clare 2 years ago, even though Limerick is half the distance away.
I urge you to use whatever power you have to make the DAFNE course available to all people with Type 1 Diabetes so that not only they benefit from it, but the Irish Health System and Economy as a whole benefit too.”

Validating a diabetes specific quality of life measure in an
English speaking population: the Irish Dose Adjustment for Normal Eating (DAFNE) Study
Diabetes-Specific Quality of Life
Mary Clare O’ Hara
Background• Diagnosis with a chronic condition can be seen as a life-
changing event – Significant change in health status – adherence to a demanding regimen
• Diabetes diagnosis has significant implications– physiological (traditional focus was on reducing levels of
HbA1c & frequency of hypos)
– psychosocial adaptation (disease self-management, how self-management regimens affect virtually all aspects of daily life)
– Negative psychological outcomes, such as depression, anxiety, and distress can present (burden/ distress, emotional health, social, physical functioning)
• Diabetes has been associated with reduced quality of life, (Goldney et al., 2004).
• Self-rated health status was significantly related with HbA1c levels amongst Type 2 diabetes patients, (Sakamaki et al., 2006).
• Physical, psychological and social quality of life are therefore viewed as critical outcomes of diabetes treatment and management, (Burroughs et al., 2004).
Quality of Life and Diabetes
Disease-specific QoL tools
• Aspects of health considered by patients and/ or clinicians to be of greatest importance
• More responsive/ sensitive to changes in health
• Assess patients concerns
• Making them important primary endpoints in clinical trials

DSQoL (77 item scale)• Specific to type 1 diabetes• Developed with patients and health professionals• Developed in Germany• Translated from German to English but remains to be
validated within an English speaking population• Scale was altered slightly from the original to reflect to
linguistic differences and more culturally appropriate scale-items.
• 57 items form 8 dimension: social relations, leisure time flexibility, physical compliants, worries about the future, diet restrictions, daily hassels, fear of hypoglycemia and daily burdens & restrictions
• 10 goal/ preference items are weighted to 10 satisfaction item = PWTSS (preference-weighted treatment satisfaction score)
ADDQoL (20 item scale)• Patient and health professional input & translated into more
than 20 languages & validated• 2 overview items - “present QoL”
- “impact of diabetes on QoL”• 18 items addressing social, physical & emotional
functioning. • Each item is scored on a 7-point scale & respondents
indicate the importance of the item in their daily lives

Statistical analysis
• Internal consistency reliability coefficient (Cronbach’s α)
• Convergent validity assessed by correlation analysis (Pearson’s correlation coefficient)
QoL subscales used & their homogeneity
0.83If I did not have diabetes, my family life would be… very much better -very much worse
This aspect of my life is… very important – not at all important
Impact of diabetes on QoL (18 items)
0.97It bothers me that I have to inject insulin before I know how much I would really like to eat or I really can eat
Daily burdens & restrictions (57 items)
0.95I am worried about having a severe episode of low blood sugar at night Fear of hypoglycaemia (11 items)
0.8It bothers me that I have to spend so much time on my diabetes treatment
Daily hassles (6 items)
0.9It bothers me that I cannot eat like other peopleDiet restrictions (9 items)
0.87I am often worried about the long-term complications of diabetesWorries about future (5 items)
0.86I suffer from thirst or having a dry mouthPhysical Complaints (9 items)
0.89Diabetes prevents me from spontaneous physical activitiesLeisure time flexibility (6 items)
0.9Because of diabetes it is much harder to make friends Social relations (11 items)
0.77For diabetes treatment it is especially important to me, or it would be my goal that … I can arrange my free time with flexibility.
How satisfied have you been over the last 4 weeks with… the flexibility in arranging your free time
PWTSS
Cronbach’s αExampleSubscale
CorrelationADDQoL
• QoL, future QoL and AWI Score were significantly correlated (r = .387, .341 and .324 respectively)
DSQoL
• All subscales were significantly correlated to each other (r between .637 and .861)
Conclusion
• High degree of internal consistency are achieved by both ADDQoL & DSQoL
• High inter-correlations confirm that the subscales involved represent a homogeneous construct of diabetes specific quality of life
• Future research within the Irish DAFNE Study will enable the responsiveness and sensitivity to change of these 2 quality of life instruments to be assessed and compared.
