Know Diabetes mentoring programme

As the number of people with diabetes increases across the UK and globally, primary care teams are taking the brunt of the increased workload. There are a few initiatives that are currently being considered throughout the UK to help tackle this, such as the increasing role of trained primary care nurses to individualise care (Health Education England, 2015) and the up-skilling of the primary care workforce by hospital specialist staff (Kar, 2012). A third option is to use peer support to assist in providing the foundation of diabetes education (Boothroyd and Fisher, 2010).

Peer support involves people sharing knowledge, experience or practical help with each other, and is usually conducted on a voluntary basis with community engagement. Following a literature review produced by Know Diabetes (Stothard, 2015), current research suggests that peer support can provide psycho-social support and education for people with a long-term condition. It helps patients put into practice what they have been taught by healthcare professionals, and helps “navigate” complex healthcare systems like the NHS (Baksi, 2010). In a systematic review of 25 studies, Dale et al (2012) demonstrated that peer support encouraged positive metabolic and mental health outcomes for people with diabetes. There were improvements to HbA_1c, cholesterol, BMI (and weight) and an increase in physical activity (Dale et al, 2012). There were also noticeable improvements in self efficacy and depression. However, positive evidence for the role of peer support in improving HbA_1c is not consistent (Foster et al, 2007), which suggests further research is required or multiple factors are involved in providing a successful peer support programme.

Know Diabetes mentoring programme
In west London, Westminster City Council, Hammersmith and Fulham London Borough Council and the Kensington and Chelsea London Borough Council have combined services, including healthcare, to form the Triborough. The Triborough area has a lower estimated diagnosed diabetes prevalence rate (4.1–4.6% for the three boroughs) than the national average of England (6%; Public Health England, 2013), which is believed to be attributed to the relatively young age profile of the area and good general health. However, within the locality, there are areas with a prevalence rate similar to the national rate (approximately 5.3%), and the lower than average diabetes rate for the Triborough area could be as a result of “under diagnosis”. The areas where the diabetes prevalence is higher have a large ethnic mix and are areas of deprivation.

In January 2012, the Know Diabetes mentoring programme was established as a pilot programme by the Public Health Department of the local authorities in the area and in conjunction with participating general practices (seven GP surgeries and five community settings). The mentoring programme was borne out of feedback from the local Diabetes Service User Group and is part of a three-pronged volunteer programme of mentors, diabetes awareness champions and diabetes educators. The initial 18 months of the tripartite pilot were half funded by a £100 000 grant from the Collaboration for Leadership in Applied Health Research and Care.

The aim of the mentoring programme is to complement the diabetes care pathway by offering patients additional one-to-one support from specially trained lay people to discuss non-clinical aspects of their condition, such as diet and activity, and to develop effective techniques and strategies to improve their quality of life. The programme builds on the work by Baksi et al (2008) and Baksi (2010) in the Isle of Wight, which showed that trained patients are as effective in imparting knowledge to their peers as specialist health professionals. However, lay tutors require appropriate training, specific to the education programme they would be expected to deliver.

Mentor profile, training and role
The mentors in the Know Diabetes programme are volunteers or have been paid by community groups. Some have diabetes, some are community health workers and some have diabetes in their families. During the pilot period from January 2012 to March 2015, three cohorts of mentors were trained. Potential mentors had to pass a standard mentoring course, which included role play and motivational interviewing skills. They also attended the X-Pert type 2 diabetes course, a one-off session on type 1, and a session on “red flag” issues run by a local diabetes nurse specialist to standardise their diabetes knowledge. Once trained, the mentors attended bi-monthly supervision sessions with the programme co-ordinator, who has a nursing background. The mentors did not give clinical advice but were able to assist with goal setting and to give the following general health information:

• Good practice in diet and exercise.
• The importance of adhering to medication.
• Availability of services locally and nationally for diabetes support.
• Explanation in lay terms of diabetes and its complications.
• Signposts to appropriate resources or healthcare professionals.

It was acceptable for a mentor to answer “Is burning pain a sign of neuropathy?”, but it was not appropriate to answer “I have burning pain. Do you think it is neuropathy?”. The topics of the sessions were led by the mentee, and the mentors completed monitoring forms after each appointment to record topics discussed and any goals set. Following the pilot, mentors developed local styles tailored to their own skill set and the relationship established with the GP surgery (see Box 1 for example).

Evaluation of the Know Diabetes mentoring programme
Retrospective clinical data were used to investigate the impact of the diabetes mentoring programme. Where possible a paired t-test analysis was carried out to elicit any significant change in clinical outcomes. Due to the small number of participants with type 1 diabetes, data from people with type 1 and type 2 diabetes were combined.

From October 2014 to March 2015, the Behaviour Change team of the Three Borough Public Health Service conducted telephone surveys of mentors, mentees and surgery staff for feedback on the mentoring programme. A qualitative analysis of the main themes discussed was completed by Collaborate using the monitoring forms completed by the mentors. A full description of the mixed methods evaluation is available at Shah and Jayatilleke (2015).

Mentee profile
Between January 2012 and March 2015, 260 people interacted with the mentoring programme. Using retrospective data from four GP surgeries, the mean age of the 193 mentees was 58 years (range 26–91 years), and approximately half were male. A total of 69% had type 2 diabetes, 18% had type 1 diabetes and for the remaining 22%, the type of diabetes was unknown. Two-thirds were insulin dependent, and participants mostly had at least one comorbidity, most commonly hypertension or mental health issues. Data on ethnicity were recorded for 160 mentees, with half being of black or minority ethnic origin.

The mean duration of mentee and mentor contact was 18 months (range 3.5–37 months) and was measured from the first and last clinical outcome measurement. For mentees who had more than one taster session, the average number of sessions attended was 4.3.

The smoking status of 138 mentees was known, and one person stopped smoking during the programme. At the end of the programme, 14% remained smokers, which is lower than the national rate of 19% (Health and Social Care Information Centre, 2016).

Mean baseline BMI was 31.34 kg/m² (n=129), mean baseline HbA_1c was 59.7 mmol/mol (7.6%; n=124) and mean baseline systolic blood pressure was 134.6 mmHg. Participants (n=58) had a mean cholesterol level of 4.5 mmol/L (range 2.9–7.1 mmol/L), and 10 had cholesterol above 5 mmol/L, which is better than would be expected given the Triborough profile data.

Following the programme, there were no significant changes in BMI, glycaemic control (post-programme 57.1 mmol/mol [7.4%]) or diastolic blood pressure. The post-programme systolic blood pressure was 131.4 mmHg (n=143), which was a significant change of –3.2 mmHg (P=0.02). Insufficient data were collected to determine a change in cholesterol.

Mentee feedback
According to the monitoring forms, the topics most often discussed were healthy eating and weight management (62%) and coping with diabetes/general education (38%). Of the mentees who participated in the telephone survey, all (n= 27) reported that the sessions had a positive impact on their diet, and 19 said they helped with managing blood glucose levels to target.

Mentor feedback
On a scale of 1–10, the 10 responding mentors experienced enjoyment (average 9.3) and overall helpfulness (average 9.1) as a result of mentoring. Four mentors found employment as a result of the work experience the role offered. They also felt being a mentor supported their own wellbeing and self-management, and, as a result, they were more active, confident, positive and happy.

GP feedback
From a prompted list of potential advantages, GPs (n=6) said that diabetes mentors were beneficial to mentees by encouraging increased activity, weight loss and heathier eating habits. They felt that the mentors reduced anxiety around diabetes and improved the mentees’ understanding about diabetes. GPs valued the mentors who had good communication skills, knowledge of local community services and were culturally aware. The surveyed GPs were confident in the mentors’ ability to discuss physical activity and healthy eating habits, and to support behaviour change and diabetes self-care. They would recommend the mentoring programme to suitable patients.

Challenges faced
Throughout the programme, a challenge faced has been the high drop-out of mentors. Only 50% of mentors recruited for training have practiced as a mentor. Some participants did not develop appropriate mentoring skills and, therefore, did not pass the mentoring course, while others left the programme because of full-time employment, life events or a need to have paid work. Additionally, there was often a time lag in matching new GP practices to mentors, which caused disengagement and further contributed to the high drop-out rate.

Initially, it was difficult to engage GP practices in the pilot scheme; however, word-of-mouth recommendations about the potential benefits of the project seemed to increase GP practices engaging with the mentors and providing referrals. We found that for the scheme to be successful, at least one or two practice members needed to engage with the mentor and make referrals. When this did not happen, the mentor was left disappointed and mentoring at that practice was discontinued. Also, we only worked with practices with a diabetes clinic, so the mentoring programme did not reach those who may have benefitted the most from extra peer support.

While mentors enjoyed the face-to-face interaction with mentees, they were less keen to complete the monitoring forms, making data collection and accurate analysis difficult. Incentivisation in the form of shop vouchers was introduced to increase recording of sessions, but this did not work. However, when mentors were able to record progress on GP systems, compliance was better.

Only four practices out of seven provided clinical data, which in some cases was incomplete. Permission to use mentee clinical data had to be sought retrospectively, so only 27 were surveyed, providing an approximate 10% response rate. Caution must be given as confounding variables were not controlled (e.g. dietitian interactions, change in practitioner or external events affecting self-motivation) and a lack of control group also limits our ability to make conclusions. Furthermore, there is a selection bias in all those who agreed to be surveyed, mentees, mentors and clinicians. Those who participated were the most engaged with the programme.

Take-home messages
The mentoring programme appears to have some positive effect on self-reported psychosocial measures, such as self-management and behaviour changes (e.g. increased activity and maintaining healthier diets). However, the impact of mentoring on clinical measures is more difficult to determine (Smith et al, 2011).

Most mentor activity was done in primary care rather than in the community, and we suggest that mentoring works best when there is a blend of enthusiastic primary care staff and a resourceful mentor. We conclude that the skill set required by mentors includes the following:

• Personal experience of diabetes.
• High level of communication skills.
• Ability to engage with diverse groups of hesitant mentees.
• Time and persistence.
• Behaviour-change skills.
• Cultural awareness and community knowledge. 

We have created a local diabetes website www.knowdiabetes.org.uk that is hosted by our Diabetes UK Education and Support Groups. It contains additional resources for our volunteers and also details of local NHS diabetes services, structured group education and where exercise classes are available.

Conclusion
There is growing enthusiasm for the mentoring scheme in the local area and there is recognition of the added value mentors provide in supporting self-care and wellbeing for people with diabetes. However, the programme will need a number of adjustments if it is to continue effectively, and it is envisaged that the programme will become part of the Out of Hospital Care Package funded by the local Clinical Commissioning Groups.
