A co-design study to develop supportive interventions to improve psychological and social adaptation among adults with new-onset type 1 diabetes in Denmark and the UK.

OBJECTIVE: To develop supportive interventions for adults with new-onset type 1 diabetes (T1D) to facilitate positive adaptive strategies during their transition into a life with diabetes.
DESIGN: The study used a co-design approach informed by Design Thinking to stimulate participants' reflections on their experiences of current care and generate ideas for new supportive interventions. Visual illustrations were used to depict support needs and challenges. Initial discussions of these needs and challenges were facilitated by researchers and people with diabetes in workshops. Data comprising transcribed audio recordings of the workshop discussions and materials generated during the workshops were analysed thematically. SETTINGS: Specialised diabetes centres in Denmark and the United Kingdom. PARTICIPANTS: Adults with new-onset T1D (n=24) and healthcare professionals (HCPs) (n=56) participated in six parallel workshops followed by four joint workshops with adults (n=29) and HCPs (n=24) together.
RESULTS: The common solution prioritised by both adults with new-onset T1D and HCP participants was the development of an integrated model of care addressing the psychological and social elements of the diagnosis, alongside information on diabetes self-management. Participants also indicated a need to develop the organisation, provision and content of care, along with the skills HCPs need to optimally deliver that care. The co-designed interventions included three visual conversation tools that could be used flexibly in the care of adults with new-onset T1D to support physical, psychological and social adaptation to T1D.
CONCLUSION: This co-design study has identified the care priorities for adults who develop T1D, along with some practical conversational tools that may help guide HCPs in attending to the disruptive experience of the diagnosis and support adults in adjusting into a life with diabetes. © Author(s) (or their employer(s)) 2021.

The study included a diverse sample of adults with new-onset type 1 diabetes from two countries.

A large number of healthcare professionals across multiple disciplines from two countries took part in the study.

The broad approach including many different perspectives increases the transferability of the results to other contexts.

Although we did not find any differences between perspectives across gender, a limitation of the study is the relatively small number of male participants.

People with diabetes have been involved in the design and conduct of the study from inception.

Introduction

A diagnosis of type 1 diabetes (T1D) can occur at any age, with around 50% of cases presenting in adulthood.1 2 Developing T1D as an adult can be very disruptive, as adults have already formed many aspects of their lives: employment, relationships and lifestyle habits.3 4 The diagnosis introduces new responsibilities for acquiring and maintaining time-consuming self-management skills, and fears about hypoglycaemia and future diabetes complications, all of which may affect self-identity and life-plans.5 6 Previous research has identified that accommodating the demands of T1D into established life routines can lead to significant psychological and social challenges for adults with new-onset T1D.7 8 These challenges include difficulties in coming to terms with the diagnosis of T1D; experiencing added complexity and disruption of daily life due to managing diabetes alongside other demands; and feeling stigmatised and anxious about how the diagnosis will affect social relationships and employment.3 4

During the disruptive period following diagnosis many adults feel that their psychological and emotional needs are not adequately addressed by healthcare professionals (HCPs).9 10 Adults with new-onset T1D perceive that the focus of their interactions with HCPs is on providing them with the technical skills needed for blood glucose management to achieve ‘good’ blood glucose levels.4 This focus, when pursued without attending to the psychological and social challenges following the diagnosis of T1D, can create a sense of frustration and failure in the person with diabetes when recommended blood glucose levels are not achieved.3 4 Furthermore, the person may consequently be less likely to engage with their self-management behaviours, thereby increasing the risk of future burdensome and costly diabetes complications.4 11 Hence, early intervention to support adults in developing positive adaptive strategies and self-management routines in everyday life following diagnosis may reduce these problems and may improve long-term physical and mental health outcomes.

National and international guidelines12 13 highlight the importance of addressing the psychological and social needs of adults with diabetes, however, there are no specific recommendations for how to address these needs in the adult onset T1D population. While HCPs generally recognise the importance of providing psychological and social support for adults with diabetes,14 15 studies have reported minimal inclusion of such issues in routine diabetes care due to lack of training, tools and skills to engage in conversations about psychological and social aspects.16–18 Furthermore, access to specialist psychology services is limited in most areas. Structural barriers such as consultation time constraints due to a focus on fulfilling the requirements set by clinical guidelines and an emphasis on glucose targets also limit the capacity for psychological and social support.9 17 Previous studies have reported that HCPs tend to overload people with information on diabetes self-management, focusing on technical issues rather than providing psychological and social support due to a fear for the person’s physical safety.4 9 Such studies have also found that this emphasis on diabetes treatment together with the risks of hypoglycaemia and long-term complications can induce a sense of anxiety in adults with new-onset T1D.4 9

Overall, existing evidence shows a disconnect between the needs of adults with new-onset T1D and current early-stage care, with potentially negative consequences in relation to the person’s acceptance of and engagement with their diabetes; thereby, increasing the risks of future physical and psychological morbidity. To address this problem, we have undertaken a co-design study with adults with new-onset T1D and HCPs in Denmark (DK) and the United Kingdom (UK). The aims were to explore care priorities for adults with new-onset T1D and to develop supportive interventions to facilitate a more positive transition into life with diabetes—physically, emotionally and socially—that could be tested in future feasibility trials.

Design and methods

The study used a co-design approach informed by Design Thinking to explore and develop interventions to support adults in adapting to T1D.19 The co-design approach in the study was aligned with the early stages of the Medical Research Council framework on developing and evaluating complex interventions to explicate mechanisms for intervention and to identify potential intervention components for future testing.20 DesignThinking typically has three integrated phases centred on stakeholder engagement and participation.21 The first phase (Inspiration) relates to exploring the target groups’ physical, social and emotional needs. The second phase (Ideation) includes a process for stimulating the target population to generate, develop and test ideas that might be a solution to the needs defined in the ideation phase. In the third phase (Implementation) prototypes developed in the ideation phase are tested.

This paper presents our findings from the ideation phase, the inspiration element of the process has been reported elsewhere.4 9 22 Prototypes that resulted from the ideation phase reported here will be tested in future feasibility trials.

Study settings and participants

The study participants were recruited from four specialist diabetes clinics in DK and two in the UK, with approximately 250 and 80 new cases of adult-onset T1D annually, respectively. The rationale for this was to consider the experiences of adults in different settings to enhance the transferability of the study outputs. T1D care in DK and the UK is similar in that it is provided by multidisciplinary specialist diabetes teams, with the only major difference being the offer of group-based evidence-based structured self-management education programmes in the UK from 6 to 12 months following diagnosis, however, the uptake is low.23 24

Eligibility criteria for study participants included: adults (≥18 years) diagnosed with T1D within the past 5 years to ensure recollection of diagnosis and HCPs with >1 year experience of providing care for adults with new-onset T1D. Of 82 adults with new-onset T1D invited to participate in the study, 36 accepted the invitation and 31 attended one or more workshops. Participants were recruited according to ethical approval in each country. In the UK, potential participants were purposively sampled to achieve maximum variation in terms of age and gender and invited by letter. In DK, eligible participants were approached by clinicians following out-patient appointments. All members of the multidisciplinary diabetes team in each clinic (ranging from 4 to 35 HCPs) were invited to participate via email.

Patient and public involvement

People with T1D have been involved in the design and conduct of the study. One person with T1D was a co-applicant on one of the grants. They were also part of the advisory group with four other people with T1D, a representative from a patient organisation and two HCPs in addition to the research team. The advisory group have played a central role in making sure that the study and its outputs are patient centred.

Data collection

We first conducted nine parallel workshops (adults with new-onset T1D in groups (n=24) and HCP in groups (n=56)) and then four integrated workshops (adults with new-onset T1D (n=29) and HCP (n=24) in a joint workshop) to stimulate the target populations to generate, develop and test ideas for new supportive interventions. Workshops were conducted from June 2018 to October 2019. Data included audiotaped discussions from all workshops which were transcribed and sticky notes and flip charts with participants’ feedback (for an overview of the process, see table 1). In the UK, three adults with T1D from the study advisory board undertook training in group facilitation together with the UK research team to co-facilitate the parallel and integrated workshops. In DK, workshops were facilitated by members of the research team. The research teams consisted of experienced clinicians and researchers.

Workshops for adults with new-onset T1D were conducted either in university or diabetes clinic rooms. Workshops for HCPs took place in the participating diabetes clinics. The parallel workshops lasted 2 hours each. The integrated workshops were also conducted either in university (n=2) or diabetes clinic rooms (n=2), they were 3 hours long with breaks for food and refreshment.

Workshop methods

The parallel workshops were structured to enable smaller group discussions to stimulate participants to reflect on their experiences. Illustrations depicting the common support needs and challenges expressed by adults with new-onset T1D and HCPs in the inspiration phase4 9 22 were used to stimulate group discussions (see figure 1 for examples). Following these facilitated discussions, participants were asked to vote on the three challenges they considered the most important to address. Brain-storming exercises in smaller groups were then used to generate as many ideas and solutions as possible related to the prioritised challenges.

Figure 1

Examples of illustrations depicting support needs and challenges. HCP, healthcare professionals; T1D, type 1 diabetes.

In the integrated workshops, adults with new-onset T1D and HCPs voted on their top two priorities and then worked together to develop interventions to address these. Ideas and solutions from previous workshops were summarised onto cards and combined with new ideas which were gradually refined to provide prototypes of tools to support adults with new-onset T1D. Preliminary prototypes were collated and integrated by the advisory board. The prototypes were circulated via email to workshop participants for verification, comments and further suggestions for refinements. Over several iterations through emails and conversations, the prototypes were further refined into a deliverable format for testing in future feasibility trials.

Data analysis

Anonymised data from the workshops were analysed thematically for common themes among the suggested ideas and solutions for each prioritised challenge across sites and countries. The analysis followed Braun and Clarke’s25 method, which is based on a five-step process:

Becoming familiar with the data by reading and re-reading the outputs from workshops (transcriptions, post it notes, summary notes), and making notes of early impressions.

Generating initial codes, through looking across the dataset to compare challenges, ideas and solutions for similarities and differences within and across sites and countries.

Searching for common themes, by comparing the relationships between the ideas and solutions related to the prioritised challenges and organising them into broader themes.

Reviewing themes, by identifying patterns across the themes and labelling overarching themes for the challenges, ideas and solutions.

Defining and naming themes through refining the relationships between the challenges and the suggested solutions and ideas.

The initial coding of workshop data was conducted by local members of the research team and discussed with the first author (MD-C). The coding was compared for similarities and differences between sites and countries in preparation for theme development. MD-C developed preliminary themes in collaboration with SS and AF (UK) and ER and JLW (DK). These were then discussed with and refined by members of the research teams across the sites during the initial steps of the analysis process. Subsequently the whole team met to agree on the final themes and prototypes of tools.

Results

Of the 31 adults with new-onset T1D participating in the study, 16 (52%) were from DK, 20 (64%) were women, median diabetes duration was 2.5 years (ranging from 1 to 4.5 years) and median age was 42 years (ranging from 22 to 72 years). Of the 61 HCPs participating in the study, 44 were from DK (71%). Thirty-six were nurses (59%), 14 doctors (23%), 8 dieticians (13%) and 3 (5%) others (ie, psychologists). They had a median of 15 years (ranging from 1 to 35 years) of experience of caring for adults with new-onset T1D (see table 2). Ten HCPs (five from each country) were men, three of whom were nurses from the UK, the remaining were doctors. Most participants were Caucasian.

Twenty-eight participants (16 adults with new-onset T1D and 12 HCPs) took part in more than one workshop.

Prioritisations

Top priorities differed slightly among the parallel workshops. The three challenges most commonly given the highest priority across the workshops for adults with new-onset T1D were: (a) coming to terms with diabetes; (b) the complexity of managing diabetes in different contexts and alongside other demands and (c) fear of hypoglycaemia, high blood glucose values and complications. The HCPs workshops prioritised the following challenges as most important: (a) balancing the clinical perspective (blood glucose regulation and prevention of long-term complications) with the perspective of the adult with new-onset T1D; (b) overloading adults with new-onset T1D with information due to fear for their physical safety and (c) difficulties with how to address psychological and social issues. The highest rated priorities from the integrated workshops were: (1) helping adults to come to terms with diabetes by addressing psychological, social and emotional issues and (2) avoiding information overload and balancing the clinical perspective with the needs of the adult with new-onset T1D to facilitate a more positive adaptation to diabetes.

Solution themes

The participants consistently suggested that diabetes care and support for adults with new-onset T1D needed to be phasic, first addressing the emotional, social and physical impact of the diagnosis, and then how to adapt to life with diabetes. Adults with new-onset T1D and HCPs both recognised the benefits of addressing psychological and social needs to enhance engagement in self-management activities and consequently reduce the risk of diabetes complications (both physical and psychological). There was a high level of agreement in the suggested solutions and ideas stated by participants (both adults with new-onset T1D and HCPs) across the two countries although the terminology used varied. Solutions to the prioritised challenges in relation to care priorities centred around four overarching themes: (1) provision of care which related to the interactions between the person with diabetes and the HCP; (2) ideal care content involved topics identified by participants as relevant and important to discuss in consultations following the diagnosis; (3) HCP care skillset, which concerned ways to support and improve HCPs skills sets and (4) organisation of care including availability and consistency of staff, timing of and mode of consultations and structure of electronic records. The themes are described in table 3 with illustrative quotes/excerpts from workshop discussions and information on how they fed into the co-designed interventions.

Table 3

Description of themes including illustrative quotes and ways the theme informed the co-design process

Overarching theme	Brief description of theme	Illustrative quotes/excerpts from workshop discussions	Impact on co-design process
Content of care	Signposting and normalising the difficult emotions related to the diagnosis were considered highly important in supporting adults in coming to terms with diabetes. Likewise, participants suggested signposting and discussing the common physical, emotional and social issues that occur following diagnosis to help adults address these aspects of living with diabetes. People need to process information on diabetes, treatment and the implications of these for daily life; but this processing can be challenging, so the information needs to be reinforced and repeated. Providing information about what adults with new-onset T1D can expect from their diabetes care, including a timeline of relevant appointments and contacts with HCPs, would help the person to see the bigger picture of their diabetes trajectory.	‘It’s going to be an emotional journey going forward. So, in the same consultation you’re getting ‘and here’s your pen and this is how you inject it. You’ve got diabetes da-da-da’—part of that initial consultation should be ‘and you are going to go on an emotional journey. You’re going to feel this, you’re going to feel that, to a greater or lesser degree.’ (PWD UK)‘It’s the whole process (of being diagnosed) they need to ask more about. In my case I saw myself as a strong and healthy guy and then suddenly the doctor admitted me to A&E. The feeling of having the rug pulled out from under you is still very real and present.’ (PWD DK)‘So why I’m here is because as a diabetes specialist nurse, getting the balance right between giving the information and being mindful of where people are at emotionally, we want to be able to think how we can do that in a way that’s safe and consistent throughout that journey. So, I do like this idea of the roadmap that we can use to try to ensure that can happen in a very busy clinic.’ (HCP UK)	Specific and detailed ideas and solutions related to content of care were used to ensure that the conversation tools address challenges participants found important
Provision of care	Participants highlighted the importance of HCPs acknowledging that adjustment to the diagnosis is an ongoing and lengthy process. Personalising information in relation to the person’s attitudes, needs and life context in line with their journey of adaptation would increase relevance and transformation of knowledge into self-management skills. Using non-judgmental and empathetic language to explain glucose targets and levels in a realistic and relative sense was recommended. Highlighting the difficulty of maintaining blood glucose values in the recommended range all the time would help improve self-efficacy and prevent adults with new-onset T1D developing a sense of failure.	‘If the HCP gave you a little bit of a kick and a little bit of a nudge so we could get closer to the emotional issues, because that takes up a lot of space. So does the practical stuff but also the emotional impact. So, you shouldn’t be allowed not to talk about it, I think.’ (PWD DK)‘Treating and managing diabetes isn’t just about keeping your blood sugars in check. It’s about understanding what it does to you as a person, understanding what it does to your life, and taking that whole system approach, which brings in the emotional side. So, considering all those aspects and making that part of the medical care.’ (PWD UK)‘I think we’re very much driven by target blood glucose, you know, 4 to 7. I haven’t said it before, but somebody said to me, ‘It would have been really good to hear if somebody had told me actually it’s not bad or don’t worry about it if the blood sugar goes to 12 or 13. We don’t give them that level of assurance in terms of what’s going to happen.’ (HCP UK)	The discussions in the workshops suggested that more than one tool would be useful to support both people with diabetes and the HCPs in building their relationship
HCP skill set	Participants recommended providing HCPs with simple strategies and tools to enhance their skills and confidence in engaging with psychological and social issues to help support adults with new-onset T1D deal with these issues. Improving HCPs’ communication skills and maintaining these skills through regular supervision with a psychologist was also highlighted.	‘I want to have a cupboard where I can just pull-out phrases and also reassurance so that I’m not patronising the patient. And some workshops where I have to attend mandatory training’ (HCP UK)‘Even though I think I’m very open and asking about things, but do I actually ask in a good way—am I sure they (the person with T1D) will open up to the questions even if they would like to?’ (HCP DK)	The need to support both adults with new-onset T1D and HCPs to discuss psychological and social issues were considered in the co-design process
Organisation of care	Participants identified a need to allocate enough time in consultations to provide more support around the time of diagnosis. Continuity of care during the initial phase was considered essential. Small teams of HCPs providing care specifically for adults with new-onset T1D would enhance consistency in the information provided. The electronic patient record should prompt HCPs to ask questions about psychological and social issues. Provision of support groups were identified as additional opportunities for support. Participants also suggested that there should be opportunities to involve family members in their care.	‘I really needed to talk to someone who not only had 10 min to tell me about how to use that (insulin) pen.’ (PWD DK)‘It’s having a relationship with someone else where you can say ‘how do you do (such and such)?’. Imagine getting the support of each other that we are in the same boat and we might be able to get new ideas, because we do things differently.’ (PWD UK)‘It is bad (not having enough time) and it must be something that we can do better. And it involves organisation, and it is about resources and prioritising to a great extent’ (HCP DK)	The conversation tools do not specifically address organisation of care. However, the value of making the tool useful in both individual and group consultations was recognised

Prototypes of tools to support adaptation

Through several cycles of feedback from adults with new-onset T1D (via email) and HCPs (via email and feedback at multidisciplinary team meetings), the co-design process resulted in the development of three prototypes of conversation tools that could be used flexibly in the care of adults with new-onset T1D.

Tool 1: the diabetes roadmap

The aim of this tool is to express how adapting to diabetes is an on-going biomedical, psychological and social process. It lays out what the person with diabetes can expect from their diabetes care during the first year. It signposts and normalises emotional and social responses that the person with diabetes might encounter when adapting to life with T1D. The tool is visual depicting a winding road starting from the point of diagnosis. Images of different types of HCPs who adults with new-onset T1D will meet during the first year are placed on one side of the road map, and on the other side examples of thoughts and questions people might have to support them in expressing their experience of living with T1D (online supplemental file 1).

Tool 2: living with diabetes

This tool focuses on the way diabetes might affect the person’s body, their thoughts and emotions and their everyday life with the aim of facilitating a dialogue on the person with T1D’s own issues and emotions. It uses visual prompts with images developed from previous research, and speech bubbles signposting various ways of adapting to diabetes. The tool also involves some specific open questions to give adults with new-onset T1D the opportunity to express and process the biomedical, psychological and social impacts of diabetes relevant to them (online supplemental file 2).

Tool 3: adapting to diabetes

Through a combination of illustrations depicting common experiences at the time of diagnosis and quotes relating to such experiences developed in an earlier study,22 this tool aims to serve as a conversation starter. Adults with new-onset T1D are encouraged to reflect on their experiences of living with diabetes, explore their own values and support them in making decisions related to self-management based on these (online supplemental file 3).

Participants suggested these tools could be used independently or in combination in both one-to-one consultations and group sessions. The advantage of one-to-one sessions was the ability to personalise the tools to reflect the life situation and specific issues of the individual. In group sessions, the tools would provide space for reflection on common challenges, sharing of experiences and normalising the adaptive process. A training manual to guide HCPs in facilitating the conversation tools will be developed to increase their skills prior to future feasibility trials.

Discussion

This co-design study included a diverse sample of adults with new-onset T1D and a broad range of HCPs from DK and the UK. Participants identified support related to coming to terms with diabetes and integrating clinical demands of treatment with the individual’s life situation as their top priorities for developing interventions to support early adaptation. The study showed that organisation, provision of and content of care along with HCP care skills were important features of optimal care. The study’s output were three visual prototype tools to support physical, psychological and social adaptation to T1D in adults. The aims of the tools are to enable reflections on the impact of the diabetes diagnosis and establishing self-management routines that will improve health outcomes long term and enhance mental, physical and social well-being for adults with new-onset T1D.

While optimal care is a global challenge and essential for all people with diabetes, the early phase of living with T1D provides a window of opportunity for adults to help them understand and come to terms with diabetes. This may assist them in adapting more positively to their condition from the outset in a way that will help them live well with diabetes in the future. In line with previous research,7 26 27 this study has highlighted the necessity of providing psychological and social support related to the disruption caused by the diagnosis and the impact this may have on identity, relationships and everyday activities for adults who develop T1D. The lack of such support in the period after diagnosis can impact and increase the risk of long-term complications,28 and might cause diabetes-related distress in the longer term.27 29 A key concept here is that early psychological and social intervention may help ameliorate or prevent the development of longer-term maladaptive coping mechanisms (avoidance or disengagement), diabetes distress and psychological morbidities (fear and anxiety) which will increase the risks for physical complications.

The ideas and solutions suggested for improving care processes at diagnosis across the participating countries were almost identical among the adults with new-onset T1D and HCPs participants. Previous research has identified commonalities between the UK and DK in relation to the experiences and needs of adults with new-onset T1D4 and the barriers of attending to these needs experienced by HCPs.9 The resemblance in healthcare service provision for people with T1D (free access paid through taxation, corresponding clinical roles for HCPs) might explain the similar perception and experiences of HCPs and adults with new-onset T1D across DK and the UK. Another explanation for the convergence between the two countries might be the universality of the challenges people experience following being diagnosed with a chronic condition as an adult.30 Older and recent studies involving adults with longer diabetes duration have demonstrated a common and persistent perception of challenges in life with T1D across a variety of settings.10 Such challenges include for example illness perception,31 32 change in identity33 34 and acceptance of and adjustment to T1D.35 36

This study showed that need for continuity, consistency and personalisation in care delivery following diagnosis was of high importance to both the adults with T1D and HCP participants. Communication, emotional support and the quality of the relationship between the person with diabetes and their HCP have been associated with long-term impacts on diabetes self-management and quality-of-life.10 37 38 Studies have also shown that adults with diabetes value interactions with HCPs that consider their mental well-being39 and acknowledge the complex multifaceted challenges of living with diabetes.40 In addition, the value of getting emotional support through peer support has also been highlighted in existent literature.41 42

Other studies have identified the difficulties and challenges faced by HCPs in providing emotionally therapeutic care, identifying the need to increase the awareness, skills and opportunities of HCPs for delivering such care.43 44 A key challenge to overcome is the need to balance clinical priorities (introducing diabetes technologies safely and setting glucose levels) with the wider needs of the person with diabetes following the disruption of the diagnosis. Integrating these different agendas in consultations might improve the consultation experiences for both adults with T1D and HCPs.45 Recently, the use of diabetes-related patient-reported outcome measures (PROMs) has been suggested as a way to incorporate psychological and social issues into consultations.46 To our knowledge, a diabetes-related PROM focusing on the psychological and social impact of a diagnosis of T1D has not yet been developed. Due to their limited experience with living with T1D, a reliance solely on PROMs would be limited in terms of meaningfully informing future practice and care. Alongside the refinement of better measures, developing tools specifically aimed at improving people’s experiences following diagnosis by raising openness and awareness about potential challenges may help integrate adults’ experiential knowledge with that of HCPs to the benefit of both parties.10 47 48

The conversation tools developed in this study will not in isolation change practice. Tools need to be underpinned by common values and understanding in terms of what is necessary for their use and who can provide the support including change of practice and collaboration and what training is needed.49 50 Multidisciplinary teamwork with input from adults with new-onset T1D and time for discussions on approaches to care for adults with new-onset T1D are likely to increase common values and engagement with and use of the tools in clinical practise. A common approach to the tools may enhance the therapeutic interactions between HCPs and adults following diagnosis allowing for a more open dialogue in relation to how people navigate the physical, psychological and social impact of developing T1D in adulthood.

While the challenges identified and prioritised in our study are in line with previous research in adults with diabetes, this study is the first to explore and compare specific solutions to these challenges among a transnational group of both adults with new-onset T1D and HCPs. Our study highlights that challenges occur from the time of diagnosis and support is needed to address these challenges as early as possible to potentially prevent long-term psychological consequences such as high levels of diabetes distress.29 51

Study limitations

While participants identified several support needs and optimal care features in relation to adult onset T1D, the outcome of the co-design process did not attend to all challenges identified in the study. In part, this was a result of the prioritisation exercises in which the focus for the development work was agreed by consensus. The result of this process was that some areas such as care organisation were not considered to the same extent as care content areas. The conversation tools, for example, mainly address the content and provision of care during consultations. However, while care organisation was not directly addressed by the conversation tools, the study did emphasise a wider focus on psychological and social challenges as part of care delivery and this was expressed in the roadmap which set a framework for care organisation. In addition, the identification of training for HCPs and enhanced continuity are systemic interventions.

There were some differences in study design between sites. Due to different ethical approval requirements, participants were recruited differently in DK and the UK. The content of some HCP workshops was adapted due to time restrictions in terms of their availability. Involvement of people with diabetes as co-facilitators in the workshops was only possible in the UK part of the study. Another area of national divergence was in relation to some aspects of care delivery. While the healthcare systems in the UK and DK are similar, the UK offers structured evidence-based group education which is not provided in DK. However, despite these small differences, our study captured the views of a large sample of both adults with new-onset T1D and HCPs from the multidisciplinary teams across several sites in both the UK and DK.

It is important to acknowledge that we did not have any inclusion criteria or collect data relating to the ethnicity of participants. Previous research has highlighted the lack of representation from people with non-White ethnicity in T1D research.52 This omission may have meant our sample lacked representation of people with Black or Asian ethnicity. In part this reflects the fact that T1D is more prevalent in Caucasians53 and the relative homogeneity of the Danish population. Therefore, we acknowledge that while the study did include perspectives of a wide range of participants across multiple settings in two countries, the perspectives of other ethnic populations or cultural settings were not addressed in the study. Future studies should address this deficit as the experiences and perspectives of people from other ethnicities may be socially and culturally nuanced.

There was a potential gender bias in the study, with more female participants in both the people with T1D and HCPs. In terms of adults with T1D more women than men participated in the study. Previous studies of people with established T1D indicate that women and men may have different experiences of diabetes and perceptions of how diabetes impacts on their lives.54 55 However, it is not established how divergent gender based experiences are at the point of diagnosis, indeed in our previous research which included both men and women in relation to their experiences of a T1D diagnosis found that areas of impact were common.4 While we did not systematically map perspectives according to gender in adults with T1D, our sample included both gender perspectives and the proposed solutions were consensus based, following the co-design methods outlined. Among the HCPs, nurses were the most common professional group, this partly reflects the fact that nurses formed the largest proportion of HCPs in the multidisciplinary teams of the participating centres. In the Danish centre, a further factor was that the nurses had greater availability at the time of conducting the workshops. It may also be that the psychologically and socially based subject matter of the research has seemed more relevant to nurses, however, studies have shown that psychological and social issues are considered to be important challenges by both diabetes nurses and doctors.56–58 However, while there were more nurses who participated in the study, there was a broad consensus across disciplines in relation to the identified themes and solutions. It is also important to note that a tenant of this research model is that all perspectives are considered relevant, as it is the ideas that they contribute rather than the volume of contribution that informs the co-design process.

Despite these limitations, we believe that due to the high level of convergence and connectivity between the views of the people with diabetes and the HCPs, the emerging ideas from the co-design process will be recognisable in the wider population and will increase the transferability of findings. Thus, the implementation of the tools is likely to be more successful if they are found effective in enhancing a more positive transition into life with T1D in future trials.

Conclusions

This co-design study has identified the care priorities for adults who develop T1D, along with some practical conversational tools that may help guide HCPs in attending to the disruptive experience of the diagnosis and support adults in adjusting into a life with diabetes. Providing more emotionally expansive support that recognises and attends to the psychological and social impact of the diagnosis, may help adults adapt more positively to their diabetes. It will be important to undertake future studies to ascertain whether such interventions will improve psychological and social outcomes, increase self-management activation and care engagement, alongside metabolic outcomes, in this understudied population.
