Abstract

Background: People with type 1 diabetes are at increased risk of eating disorders. ‘Diabulimia’, ‘Syndrome of Insulin Omission’ and ‘Type 1 diabetes and Disordered Eating’ (T1DE) are all terms used to describe the omission or restriction of insulin in type 1 diabetes for fear of weight gain. For consistency, Type 1 diabetes and Disordered Eating (T1DE) is used throughout this article. The condition is associated with a significant increase in morbidity and mortality but is not yet recognised as a unique entity.

Aim: To determine healthcare professional awareness and knowledge of eating disorders in type 1 diabetes.

Methods: A short, cross-sectional, online healthcare professional survey across primary, secondary and community settings.

Results: Healthcare professional confidence is low when it comes to recognising and supporting people with T1DE, but there is an interest in learning more.

Conclusion: The findings from this study support strategies to improve healthcare professional awareness of T1DE.

Introduction

The careful attention to diet and lifestyle required to manage type 1 diabetes puts individuals at increased risk of developing eating disorders.1 ‘Diabulimia’, ‘Syndrome of Insulin Omission’ (SIO) and ‘Type 1 Diabetes and Eating Disorder’ (T1DE) are used to describe the practice of insulin restriction or omission for fear of weight gain in people with type 1 diabetes. For continuity we will refer to T1DE throughout the rest of this article.

The prevalence of T1DE is difficult to quantify. Studies have demonstrated an increasing prevalence with age rising from 1% in pre-adolescence2 to 27–39% in late adolescence and early adulthood.3–5 Most screening tools suited to the general population do not accurately detect the presence of disordered eating in people with type 1 diabetes as they focus on behaviours that are inherent to diabetes management.6

T1DE is associated with significant morbidity and mortality.7 Prolonged periods of high blood glucose resulting from insufficient insulin puts these individuals at profound risk of irreversible microvascular complications including retinopathy, peripheral neuropathy, renal disease and autonomic dysfunction.4,5 There are also short-term consequences including electrolyte imbalance, volume depletion, increased risk of yeast and bacterial infections, muscle atrophy and diabetic ketoacidosis. Over an 11-year study period, women with type 1 diabetes who restricted their insulin for fear of weight gain were 3.2 times more likely to die over the study period.7 They also died on average 13 years younger than those who didn’t restrict insulin.

In light of the severity and impact of T1DE on those affected, designing care pathways and services to support these individuals is of great importance. One of the challenges is the identification of those affected by the condition. Healthcare professionals likely to encounter people with T1DE need to have confidence to engage in early detection, understand the increased risk prevalence and feel comfortable supporting, sign-posting and/or referring on to appropriate services.

Combined Pathway for Assessment and Support for the Syndrome of Insulin OmissioN – Type 1 Diabetes (ComPASSION) is one of two NHS England-funded pilot projects focusing on the development of services to help people with T1DE. It is currently running in Wessex, led by Dr Helen Partridge, consultant diabetologist at The Royal Bournemouth Hospital, and Dr Carla Figueiredo, consultant psychiatrist at Dorset HealthCare University NHS Foundation Trust. The aims of the ComPASSION project are to trial, test and evidence the impact of an integrated diabetes and mental health pathway for the assessment, referral and treatment of T1DE. The other NHS England-funded T1DE pilot project, led by Professor Khalida Ismail at King’s College Hospital, has a focus on those with severe symptoms of T1DE.

To understand the requirement for training amongst healthcare professionals in identifying, sign-posting and referring individuals with or at risk of T1DE, we designed a local cross-sectional staff survey to help inform the ComPASSION project. Data from this will highlight the learning needs across settings (eg, primary care, secondary care and community services), and different healthcare professional groups. It will also establishhow healthcare professionals would like training to be delivered.

Aims

  • To establish the awareness of T1DE amongst healthcare professionals locally across primary, community and acute healthcare settings who may come into contact with individuals affected by the condition.
  • To determine the awareness, confidence and competencies of healthcare professionals in:
  •  being able to identify individuals with T1DE
  •  supporting people with T1DE
  •  knowing where to refer to for further support in managing T1DE

Methods

Study design

A cross-sectional, self-report, online survey using Survey Monkey was designed to gain data from a large cohort of healthcare professionals. Informed consent was recorded at the beginning of the electronically completed questionnaire. Responses were anonymous but participants were able to provide their email address to be contacted again at a later date for further studies. The study was approved by the Health Research Authority and Health and Care Research Wales: REC reference 19-HRA/4284; IRAS number 269186.

Study participants

Study participants included healthcare professionals in patient facing roles who may encounter individuals with type 1 diabetes and/or eating disorders as part of their day-to-day clinical practice. The study was limited to the geographical area of Wessex (Hampshire and Dorset) and was advertised to those working in acute trusts, primary care, community pharmacies, specialist diabetes services or specialist mental health settings including, but not limited to, eating disorder services.

Inclusion criteria

  • Male or female, aged 18 years or above.
  • Working as a healthcare professional in the geographical area of Wessex.
  • Working in a patient-facing role where they may encounter people with type 1 diabetes and/or an eating disorder.

Exclusion criteria

  • Those unwilling to participate.

Recruitment

Hospital trusts in Wessex advertised the study to potential staff participants using their intranets, newsletters and emails. The study was also promoted to general practitioners and community pharmacists through existing clinical networks including the Clinical Research Network for Wessex and the Local Pharmaceutical Committees, respectively. The initial recruitment period was 12 weeks but was extended to six months to facilitate recruitment. This population was chosen as it represents the catchment area of the pilot ComPASSION project.

Results

Demographics of respondents

848 healthcare professionals completed the survey in primary and secondary care across Dorset and Hampshire. There was a proportionate spread of respondents across the two counties (Hamphire 52%, Dorset 48%). A majority of respondents (724, 85.4%) answered all questions on the survey. A breakdown of the respondent healthcare teams and their varying roles is shown in Table 1 and Table 2, respectively. A significant proportion of respondents were female (78.2% female vs 20.2% male). A small proportion (1.6%) preferred not to disclose.

Current confidence levels around identifying an eating disorder in the context of type 1 diabetes
756 of the 848 (89%) respondents answered this question. As depicted in Figure 1, the majority of respondents had low confidence in recognising T1DE. Confidence levels across a selection of healthcare professional groups are shown in Figure 2. Of the 39 (5.2%) individuals who described themselves as ‘very confident’, only five (12.8%) regularly manage people with T1DE.

587 Brewster Figure 1587 Brewster Figure 2

What would make you consider a diagnosis of an eating disorder in the context of type 1 diabetes?
This was answered by 739 (87%) respondents (Table 3 and Figure 3). Additional comments given by respondents that would prompt them to consider T1DE included those shown in Box 1.

587 Brewster Box 1

587 Brewster Table 3587 Brewster Figure 3

Have you ever managed or been involved in the care of someone with type 1 diabetes and an eating disorder before?
Of the 735 (87%) respondents who answered this question, a majority (68.4%) had never managed or been involved in the care of someone with type 1 diabetes and disordered eating. Only 7.3% of the 232 people who had, do so regularly as part of their job.

If you have managed or been involved in the care of someone with an eating disorder in the context of type 1 diabetes, what went well or not so well?
Respondents who had been involved in the care pathway of someone with T1DE commented on what they felt had previously gone well or not so well, including the challenges and/or successes they encountered.

Many of the comments from respondents we attributed to describing a patient-centred approach. Five interdependent themes emerged which we felt fed into this (Figure 4).

587 Brewster Figure 4

1. A Multidisciplinary Approach

A multidisciplinary approach to care was described as important by many of the respondents, particularly to facilitate joined working, the sharing of decisions and management of risk (Box 2a). When a cohesive multidisciplinary team approach was lacking, this precipitated distress amongst those involved, particularly the patient (Box 2b).

587 Brewster Box 2

2. Communication

The different skill sets of healthcare professionals can be complementary and constructive in identifying and supporting someone with T1DE, but good communication with the individual and between services and healthcare professionals is required and can encourage continuity of care (Box 3a).

The use of appropriate language – particularly with the patient – was deemed important, in addition to being direct and transparent, helping to create a safe environment where everyone involved can be encouraged to be open and honest (Box 3b). Some healthcare professionals felt ill-equipped at using appropriate language or had identified colleagues using approaches they felt uncomfortable with (Box 3c). Difficulties stemmed from knowing how to communicate effectively whilst maintaining rapport when features of the illness led to a mismatch between objective measures and subjective accounts given by the individual (Box 3d).

587 Brewster Box 3

3. Training of healthcare professionals

Training of healthcare professionals to facilitate recognition of T1DE, use of appropriate consulting skills and sign-posting to local services were all described by respondents as a fundamental part of care. Most respondents felt they didn’t have the relevant expertise and expressed a wish for this to be addressed (Box 4a).

Healthcare professionals attributed blame to their lack of knowledge as a contributing factor to missed or late diagnoses of the condition, inappropriate management or unease when supporting someone with the condition (Box 4b).

A lack of recognition of the condition as being a unique entity, distinct from either type 1 diabetes or an eating disorder in isolation was highlighted (Box 4c). Where possible, healthcare professionals want to be able to attempt to understand the underlying drivers to the behaviours they were seeing to be able to offer a more patient-centred approach (Box 4d).

587 Brewster Box 4

4. Appropriate service provision

The need for a clear patient pathway with adequate availability of appropriate services was described. Respondents articulated difficulties in accessing support, particularly mental health support (Box 5a). Respondents felt that existing services are not always appropriate, joined up or equipped to manage (Box 5b).

587 Brewster Box 5

5. Perceived engagement

A challenge raised by healthcare professionals included managing the different aspects of the two conditions which have a significant impact on one another (Box 6a). What was termed ‘disengagement’ and the behaviour of non-attendance at appointments were recognised as issues when trying to offer best care (Box 6b).

587 Brewster Box 6

How confident do you feel talking to someone you think may have an eating disorder and type 1 diabetes?
In support of the comments from the previous question, a majority of 735 respondents felt they had ‘no confidence at all’ (32%) or only ‘some confidence’ (39.5%); 20% were ‘fairly confident’, 5.7% ‘very confident’ and 2.9% were ‘not sure’.

How confident do you feel about offering advice and support around insulin/diabetes/weight management for someone with type 1 diabetes and an eating disorder?
Most of the 730 responding healthcare professionals are ‘not confident at all’ (54.5%) or class themselves as ‘somewhat confident’ (27.4%) or ‘not sure’ (3%) in offering advice and support around insulin/diabetes and weight management. Of those that felt more confident (12.5% ‘fairly confident’, 2.6% ‘very confident’), there was no clear association with their underlying job role.

Thirty out of 76 diabetes specialist doctors/nurses completing the survey (40%) classified themselves as ‘fairly confident’ or ‘very confident’ in offering advice and support around diabetes, insulin and weight management. In comparison, this was the case for one out of four psychiatrists (25%), eight out of 131 general practitioners (6%) and six out of 24 dietitians (25%).

Education on type 1 diabetes and eating disorders
66.6% of the 732 respondents had never received any education on T1DE. The varying modes of education delivery and their frequency reported by the 33.4% of respondents who had is shown in Figure 5.

587 Brewster Figure 5

Other forms of education described by respondents included personal reading/study, webinars, a television documentary and personal experiences when they themselves or a family or friend had been affected.

How confident do you feel knowing where to turn for additional help/support when you have identified someone with type 1 diabetes that you are concerned may have an eating disorder?
123 of the 731 people who completed this question (16.8%) were ‘unsure’ or ‘don’t feel confident’ knowing where to go to seek additional support when concerned about someone they feel may have T1DE. The services to which people would go are shown in Figure 6. 5.2% of people would consult all of the options listed.

587 Brewster Figure 6

When invited to offer additional comments, respondents suggested that they would additionally consider contacting their senior, a dietitian, team psychologist, diabetes counsellor, general practitioner with a specialist interest in diabetes or a diabetes pharmacist.

Further education on eating disorders in type 1 diabetes and the services available locally
A predominance of the 730 respondents (71%) expressed an interest in receiving further education on T1DE and the services available locally to them. 6.6% were not interested and the remainder selected ‘maybe’ as an option.

When asked about mode of delivery, a majority (64%) would like to have further education take place in a face-to-face format, with 28% having selected this as their only preference. Additional comments identified that respondents would want this to take place locally at the work place or for study time to be allocated to it (eg, a study day), ideally with a certificate for Continued Professional Development (CPD). Just over half of respondents (52%) would be happy with an online format including online webinars and tutorials, with 15.8% choosing this as their only preference. A significant number would also be comfortable with an information pack (41.5%), but only 9.5% would be happy for an information pack in isolation. 15.5% selected all three options.

Additional closing comments
The survey was well received and felt to be a subject worth better understanding by a majority, but for some the subject was felt to be very specialised (Box 7a). It highlighted a knowledge gap for many but an appetite for learning more (Box 7b). An interest in a patient pathway and information and clarity on local services was expressed (Box 7c). Some additional considerations and thoughts were also highlighted in the respondents’ comments (Box 7d).

Discussion

Main findings

The results from this survey have provided an insight into the underlying awareness and understanding of T1DE amongst healthcare professionals and concerns they have relating to this topic. Interestingly, a large majority of respondents were female. It could be speculated that males prefer not to complete surveys or are less interested in the subject area, or perhaps females make up the greater proportion of the healthcare professional pool amongst which the study was promoted. From the data collected, it is not possible to attribute an explanation to this finding.

A significant majority of respondents had no or only limited confidence in recognising T1DE. This was true across different speciality groups and healthcare settings represented in this study. A majority had never previously managed or knowingly been involved in the care of someone with T1DE.

Comments from a variety of participating healthcare professionals have highlighted how people with T1DE may only get picked up when at crisis point, presenting with complications including diabetic ketoacidosis and foot problems amongst others, or flagged as having missed their annual diabetes reviews. Increasing recognition and appreciation of the condition amongst healthcare professionals may facilitate earlier intervention to support affected individuals.

‘Weight loss’ and ‘disclosure from the individual’ were the two most selected identifying features for T1DE selected by the participants. Both features are unreliable – people with T1DE rarely disclose it and T1DE is less frequently associated with the same degree of weight loss as is typically seen in anorexia nervosa. ‘Elevated or rising glycaemic control’ was the least frequently selected option and ‘restriction of insulin’ was considered a feature by 69.7% of healthcare professionals. Both of these are suggestive of T1DE in association with an individual’s concerns about their body weight or body image.

As published work suggests, the differing terminology used to describe the behaviour of insulin omission in type 1 diabetes for fear of weight gain can lead to confusion. The condition is not currently recognised as a unique entity in psychiatric classifications. In this context, low confidence in recognising and managing T1DE may explain why difficulties arise when trying to find specialist care to support those affected.

There was an impression and concern that limited services are available to support people with T1DE and that healthcare professionals were not confident about who or where to refer for support with someone they are concerned about.

Germane to the work of the ComPASSION project, healthcare professionals expressed an interest in knowing more about services available locally and where to sign post to. An appreciation for the importance of appropriate language was expressed alongside an interest in having training on suitable consulting skills.

Strengths and limitations of this study

To our knowledge, this is the first study of its kind assessing healthcare professional awareness of T1DE, however caution must be taken when drawing conclusions from some of the findings. There was not an equal or proportionate representation of each healthcare group. Some questions were also not answered by every respondent, which will have had an impact on the quoted figures. The survey was open for approximately 6 months (1 October 2019 to 31 March 2020), but due to participating trusts and organisations advertising it internally using differing strategies, this may explain why some were better represented than others. With the survey only being available and accessible to respondents online, this may have introduced bias, although it can be inherently assumed that most healthcare professionals have access to this technology.

The study population and geographical area was chosen as it represents the catchment area of the Wessex led ComPASSION pilot project which it was designed to inform. Whilst it is not possible to generalise the findings to other populations, the counties of Dorset and Hampshire are diverse. They include major cities like Southampton and Portsmouth and a large rural geography. In contrast to some regions, however, according to the last Census in 2011, Wessex has a greater proportion of people aged 65 years and over (Dorset 28%, Hampshire 17.1%) compared with the national average (18%).8,9 They also have lower levels of black and minority ethnic residents (Dorset 4.4%, Hampshire 8.2%) compared with the country as a whole (19.5%). In terms of deprivation, 10 out of a total of 219 areas in Dorset are within the top 20% most deprived nationally for multiple deprivation. In Hampshire, 40 out of 832 areas are in this category.9,10

The ComPASSION project has been publicised in Wessex. As the survey was carried out in this area, there is the possibility that the number of people who are aware and confident of T1DE may be over-represented compared with healthcare professionals working in other areas.

Finally, as with all surveys, individuals invited to take part who choose not to respond are a unique group in their own right. We are unable to comment on the reasons individuals chose not to participate or draw conclusions on their appreciation of the subject matter. The same applies for those who completed the survey but skipped various questions.

Implications for future research, policy and practice

The findings from this study will contribute to the ComPASSION project and facilitate the development of initiatives to raise awareness of T1DE and improve the knowledge and skills set of those working in settings where they are likely to encounter individuals with the condition. The results suggest that generic initiatives are important to raise global awareness, but more tailored approaches are required to meet the specific needs of differing staff groups and/or settings. As with other forms of diabetes training, education on type 1 diabetes and disordered eating could be delivered in levels/tiers. Level 1 could focus on raising awareness of the condition in the vast majority of healthcare professionals. Progressing levels would aim to deliver increasing quantity and depth of training for those likely to encounter and be involved in the management of the condition.

In terms of education delivery, face-to-face teaching was popular but the flexibility of online methods was also appreciated. Approved study time to complete the training was voiced as being important. To encourage uptake, accreditation of any learning material should be considered.

Conclusions

T1DE is associated with significant increased morbidity and mortality. Healthcare professional confidence in recognising and supporting an individual whom they suspect may have an eating disorder in the context of type 1 diabetes is low across Dorset and Hampshire. This survey supports the work currently being done as part of the ComPASSION project, developing a patient pathway for those affected by T1DE. Healthcare professionals who are in roles where they may encounter someone affected want to know how to confidently recognise the condition, how to best support individuals and, importantly, how to access the services available to them locally. Where possible, this teaching should be relevant to the role and healthcare setting of the individual, accessible and supported by employers.
