Structured education is recommended for all people with diabetes; however, few interventions for children and adolescents with type 1 diabetes in the UK have been described. The present study was conducted as part of an ongoing project to develop a new programme for 11–16 year olds, suitable for implementation within the National Health Service. Ninety-five diabetes specialist nurses, working in paediatric clinics, completed a survey examining current provision and design of both ongoing and more formal, structured diabetes education in their centre, as well as their views on the perceived difficulty of implementing the new education programme in their centre. Approximately half of the nurses responding had some kind of formal, structured education in place at their clinic. Overall, respondents perceived the proposed education course as difficult but achievable. In those centres already providing additional, formal sessions, it is necessary to ensure that good practices are shared and that education is evaluated. The proposed education course was thought to be of potential value; however, the potential problems – including parental anxiety, staffing and resource issues, and the suitability of the course for less motivated or mature people – must be overcome.

It is widely accepted that people with diabetes may benefit from formal, structured education. People need skills, knowledge and confidence to implement self-care, to adhere to treatment and to make decisions about the impact of treatment on their daily lives. The National Service Framework for diabetes (Department of Health, 2001) states that:

‘the provision of information, education and psychological support that facilitates self-management is the cornerstone of diabetes care.’

Further, the National Institute for Health and Clinical Excellence (NICE; formerly the National Institute for Clinical Excellence) recommended that formal, structured education be made available to everyone with diabetes (NICE, 2003). Specific recommendations were also made for children and adolescents both at diagnosis and on an ongoing basis (NICE, 2004).

This education is of special importance for children and adolescents, since glycaemic control typically declines during this stage of life (Amiel et al, 1986; Mortensen et al, 1998; Dabadghao et al, 2001; Du Pasquier-Fediaevsky et al, 2005). This is thought to occur because of a combination of hormonal changes during puberty and psychosocial factors (Hamilton and Daneman, 2002), such as decreased parental support and non-adherence to the treatment regimen. Daily tasks involved in self-care can conflict with the goals of adolescence, impinging on young people’s need for independence and making them feel different from peers, which can result in non-adherence to the treatment regimen.

Education to empower people may be one way of aiming to improve control. However, few interventions have been published  in the UK (Hampson et al, 2001). This does not mean that children and adolescents are not receiving any education. For example, Llahana et al (2001) surveyed 66 paediatric diabetes specialist nurses (PDSNs) and found that all provided ongoing education, using a variety of methods including group and individual sessions, activity weekends and fun days. In the authors’ experience, a great deal of ad hoc education takes place within the clinic setting. What is unclear is the amount and type of formal education that goes on in the UK. (‘Formal education’ can be defined as optional education sessions that have a written curriculum, have clear aims and last for a predefined period of time, and they are often taught in a group setting).

The Dose Adjustment For Normal Eating (DAFNE) programme
Given the lack of fully evaluated formal paediatric diabetes education in the UK, the authors decided to explore the value of adapting an existing adult programme – the DAFNE programme. This week-long course teaches individuals to adjust their insulin dose to match the carbohydrate content of their chosen meal, allowing individuals to adopt more ‘normal’ eating patterns. A randomised controlled trial of the adult course found that people had significantly improved glycaemic control and quality of life – which was sustained at 12 months – despite the need for blood tests and injections at least four times per day (DAFNE Study Group, 2002).

The programme is currently designed for people over the age of 18, but it has considerable potential to be used for people between 11 and 16 years old. They can eat more of what they want, can do activities after school and generally have greater freedom. Against this, they would need to cope with having at least four injections and blood tests per day, which may be especially challenging as it would involve self-management during school time. Further, carbohydrate counting and calculation of insulin dosage may present difficulties.

As a first stage in developing the paediatric curriculum, the authors conducted a survey of UK nurses working in paediatric diabetes centres concerning current educational practices, with two primary goals:

  • to establish the current provision and format of paediatric diabetes education in the UK
  • to assess nurses’ views on the difficulties involved in implementing a DAFNE-type approach in paediatric settings.

Methods
Participants
Surveys were posted to 130 diabetes specialist nurses (DSNs) working in paediatric clinics in the UK. Contact details were obtained from the Diabetes UK register for specialist nurses. Where no details were provided, letters were sent out to the clinic or hospital, addressed to the PDSN. A covering letter explaining the purpose of the questionnaire was included.

Questionnaire
A structured questionnaire was developed based on discussions with the multidisciplinary team, including consultants, PDSNs, dietitians and psychologists. The final questionnaire included a combination of closed and open-ended questions and consisted of two sections:

1. Current provision of education
Twenty-three closed questions covered the current provision of both ongoing and formal education sessions. Nurses were asked to indicate how many of these sessions were held per year, how long they lasted on average and who taught the sessions. Questions also covered the provision of specific types of ongoing education, including that taught in individuals’ schools, insulin dose adjustment and nutritional guidance.

2. Perceived difficulty of implementing a paediatric DAFNE-type course
Nurses were asked to indicate the perceived difficulty experienced in implementing seven DAFNE management tasks in a paediatric setting (see Appendix 1 for the questions asked on the questionnaire):

  • having at least four injections per day (including during school time)
  • blood testing before each meal
  • working out the carbohydrate content of food
  • adjusting insulin dosage
  • parents allowing children greater responsibility for self-management
  • support from schools
  • overall difficulty.

Choices were on a 5-point Likert-type scale (1 = ‘no problem’, 2 = ‘fairly easy’, 3 = ‘difficult but achievable’, 4 = ‘fairly difficult; would need a lot of support’, and 5 = ‘impossible; refuse to do it’). There was also a single open-ended question asking respondents for any other comments concerning the implementation of a DAFNE-type course for 11–16 year olds with diabetes.

Analysis
Data from all returned questionnaires were entered into a computer statistics program (SPSS version 10, Chicago, IL). Frequencies and descriptive statistics were generated. Further, in order to explore the relationship between current educational practices and perceptions of the difficulties involved in implementing a paediatric DAFNE-type course, a series of t-tests was conducted. Data from the one open-ended question were analysed using the qualitative method of thematic analysis (Polit et al, 2001).

Results
Response rate
Ninety-six responses were received (giving a response rate of 73.8%). Responses were distributed across all National Health Service regions in the UK. Seventy-six respondents were PDSNs (79.2%), six were paediatric community sisters (6.3%), four were DSNs (4.2%), two were clinical nurse specialists (2.1%) and eight did not include their name or job title on the returned survey (8.3%).

Paediatric Diabetes Education in the UK
Diabetes education is provided in all centres through a variety of methods. All centres offer ongoing education during routine clinic appointments and home visits. Written material is provided for reference: 76% of centres use their own literature; 80% use material developed by Diabetes UK; and 84% use material developed by drug companies.

Important components of this education are the provision of information to individuals’ schools, dietary education and insulin dose adjustment skills:

  • School education: 90.6% of nurses stated that they always do a school visit at diagnosis.
  • Dietary education: all centres provide comprehensive nutritional advice on all food groups. Education also includes counting of carbohydrates (36.8% of centres), counting of portions (32.6%) and counting of carbohydrate exchanges (16.8%) in a number of centres.
  • Insulin dose adjustment: insulin dose adjustment is taught in all centres. Written reference material is provided by just over half of the centres (51.0%). Most centres also teach insulin dose adjustment skills for use during times of illness (90.5%).

Formal education sessions
Respondents indicated that a programme of formal education is available in 49.5% of centres. The most common structures of these education sessions are displayed in Table 1. Sessions are often age-banded (61.7%), and several responses indicated that groups are banded using a primary school–secondary school distinction. Over 75% of these centres provide people with reference material to take away from the sessions.

Perceived difficulty of a paediatric DAFNE-type course
Mean scores from the individual questions fell between 2.73 and 3.35 (Table 2), indicating that most responses fell around the ‘difficult but achievable’ category. Parents allowing their children greater responsibility for self-management was perceived as the most difficult to achieve.

Based on these responses, a mean difficulty score over the seven items was calculated for each respondent, again with scores ranging from 1 (‘no problem’) to 5 (‘impossible). The authors were able to use data from 88 surveys; the remaining eight were deemed unsuitable because they contained missing data for more than one item. Cronbach’s alpha (Cronbach, 1951) was calculated to be 0.76, which indicated acceptable internal consistency of this scale. The mean overall difficulty was 2.97 (standard deviation [SD], 3.48), again indicating that most responses fell into the ‘difficult but achievable’ category.

The authors were interested in the relationship between the current educational practices of centres and nurses’ perceptions of the difficulty of undertaking a DAFNE-type approach in children and adolescents. A series of t-tests was conducted between the difficulty scores and a number of items concerning current educational practice. Nurses working in clinics who currently run formal education sessions gave significantly higher difficulty ratings (mean, 3.10; SD, 0.50) than those working in clinics not currently running such sessions (mean, 2.86; SD, 0.49; t, 2.28; degrees of freedom, 86; P=0.025; based on all 88 valid responses). However, nurses working in clinics already teaching carbohydrate counting gave significantly lower difficulty ratings (mean, 2.78; SD,  0.44) than those in centres not teaching carbohydrate counting (mean, 3.10; SD, 0.49; t, 0.30; degrees of freedom, 80; P=0.004; based on the 82 valid responses with this question answered).

When asked for any other comments, 61.5% of nurses provided information (the results of a qualitative analysis of these results are shown in Table 3). Although a number of comments were very positive (such as ‘This does appear the way forward – parents are asking now about the courses’ and ‘[This] sounds like a very exciting and needed project’), the majority of respondents expressed worries and issues to be considered.

The main area of concern was that only very motivated and mature children would be able to cope with the new regimen (such as ‘It would only work really well with very motivated children’ and ‘We need to select motivated families and provide the education and support’). This may link with the worries surrounding school-time injections, eating disorders and parental anxiety, for example. A second theme to emerge related to the practicalities of running a paediatric DAFNE-type course. Several respondents were worried about the amount of staff needed to run such a course, since staffing was already an issue (such as ‘I am the only PDSN for 165 children’ and ‘[there is a need for] more re-education clinics [and] extra appointments or home visits while getting established, [which means] more nurse time initially’).

Discussion
The study has provided some useful results, in terms of both current paediatric education and the potential for a paediatric DAFNE-type course.

In agreement with Llahana et al (2001), the authors found that all centres provided ongoing education to their young patients by means of regular clinic contact and home visits. However, fewer centres had regular, formal education sessions held in addition to this clinic contact. Just under half of the respondents indicated that they had some form of formal, group education in place at their centre. This finding was in accordance with the Audit Commission’s report entitled Testing Times (Audit Commission, 2000). Most centres only held between one and three sessions per year. Given that the average health district has over 100 young people with type 1 diabetes (British Diabetic Association, 1996), it is unlikely that the current provision will include all patients. Clearly, there is still a long way to go before reaching NICE’s goal of structured education being made available to everyone (NICE, 2003).

However, it is encouraging that some centres have formal methods in place for educating children and adolescents with diabetes. Evidently, a great deal of time and effort is currently spent on this education and in producing material. For example, over three-quarters of nurses indicated that reference material given to people was specially produced at their centre. It is of great importance that these ‘good’ practices are shared and that educational methods are fully evaluated, in order to carry out further research in this area and to develop knowledge about methods of best practice for educating this age group.

Implementation of a paediatric DAFNE-type course
When asked for their opinions on the difficulty of adopting a paediatric DAFNE-type approach, most nurses felt that it would be difficult but achievable. It is promising that nurses working in centres that already teach carbohydrate counting (a key component of the DAFNE-type approach) perceived fewer difficulties in delivering the programme to young people compared with those not teaching carbohydrate counting, implying that this concept may not prove as difficult to teach as was originally anticipated.

There are two main concerns about implementation. First, the approach will only be suited to the very motivated, and therefore alternative (or additional) methods will still need to be available. Second, nurses in centres already holding formal education sessions perceived more difficulties in delivering a paediatric DAFNE-type programme compared with those in centres not providing such sessions. This finding suggests that these nurses have already experienced problems when running education courses. For example, a number of nurses commented on difficulties in encouraging people to take part in sessions, and the qualitative analysis of additional comments highlighted concerns relating to the extra time and resources needed.

It is important to address these concerns in the development of any education programme and ensure that teaching does not impinge on educators’ personal time and resources, since the results of the qualitative analysis suggest that this is one factor preventing centres from running courses at present.

Conclusion
Only half of the nurses who responded to the survey indicated that their centre had a programme of formal education available. It appears that time and staffing issues are common barriers to beginning a programme of formal education. In those centres already holding sessions, much time and effort is put into educating children and adolescents with diabetes. However, in order to carry out further research in this area it is important that ideas are both shared and evaluated. 

The DAFNE programme holds considerable promise for improving glycaemic control and quality of life in children and adolescents with diabetes. However, in developing the paediatric curriculum it is important that particular attention is paid to ensuring that the additional demands are carefully considered and do not impinge adversely on staff time. Staff who are already involved in delivering programmes based on carbohydrate counting have considerable expertise and much to offer on further development of the curriculum. The programme does involve concepts that are difficult for younger people to understand. Consultation between specialist nurses, other health professionals and teachers is therefore essential in order to facilitate communication of these difficult concepts and to promote school and family atmospheres conducive to good management.
