A Tale of Two Patients
The good, the bad and the negligent
Jacq Allan, Director Diabetics with Eating Disorders (DWED)
Introductions Clara* 23 • Diagnosed as a child • Struggled in Paediatric care after being told by DSN she was ‘getting fat’ • Fear of attending clinic thereafter
* identities have been changed
Sofia* 34 • • • •
Ballet dancer Diagnosed as an adult History of previous anorexia Realised quickly that insulin omission led to weight loss
Flashpoint – the GP Clara • Sought help from the family GP and was told ‘it’s just a phase’ • Undiagnosed need for psychological support • Changed GP practise • 18 month waiting list after being referred for Cognitive Behavioural Therapy
Sofia • Referred to the Diabetes Clinic • Urgent referral sent immediately to the local Eating Disorder Unit • Communications to both Eating Disorders and Diabetes teams
Flashpoint –emergency department Clara Frequent ED attendance 5 admissions in 6 months No mental health assessments Blood sugar regulated via sliding scale • Reported that the nurses ridiculed her – a DWED trustee confirmed this via an audio recording from the ward. • Described her as ‘a non compliant’ diabetic • Discharged with no follow up • • • •
Sofia • ED attendance • Discharged with no admission • Follow up appointment with Consultant and DSN arranged for a week after discharge.
Flashpoint – diabetes clinic Clara
Sofia
• Low frequency of appointments • Built a good rapport with DSN • Lost contact with clinic after the DSN left • Behaviour of the clinical staff impacted patient’s confidence - Was told ‘there was only so much they could do if she was unwilling to be compliant’ - Her consultant made her feel ‘guilty, stupid & small’
• Flexible appointments with DSN - often this was once or twice a week • Followed up with phone calls when appointment frequency tailed off • Positive reinforcement to keep working towards goals rather than chastising her when she slipped up • Signposted to support networks
Flashpoint – the eating disorder clinic Clara – Inpatient • • •
• • •
Given anorexia feeding plan despite a normal BMI Only diabetic patient ever treated on the unit Vomiting due to Gastroparesis not bulimia - Given more food leading to dangerous hypos after each episode Advocates involved (MIND and DWED) but consultant refused to engage Nurses told her ‘she wasn’t special and that she had to get over herself’ (overheard by DWED trustee) Premature self discharge at 3 weeks
Sofia – Outpatient • •
•
•
Sought external support for diabetes care Personalised diet plan created by patient, DSN and ED team (included a plan for when she binged, didn’t want to inject insulin or restrict caloric intake) Regular Care Planning Appointments involving a DWED advocate, DSN and ED Dietician Cared for in the Eating Disorder service for 18 months
Flashpoint - Aftercare Clara • Completely lost faith in the system • Relapsed after discharge within 1 week • Attended ED • Died within 1 month
Sofia • Regular follow up by diabetes clinic particularly DSN • Maintained support network • Over 2 years of successful recovery • HBA1c > 9 on an insulin Pump • Runs own business • Single mum of 2 young girls

Talk Map • How are we doing for current treatments for diabetes and eating disorders? • What is the theoretical rationale for eating disorder treatment? • How can we adapt this model to explain the two fold increase in eating disorders in people with diabetes? • What targets should we treat?
ED Treatment Outcome (Custal et al 2014)
T1DM patients (50%) stopped treatment significantly earlier (χ2 = 4.50, df = 1, p = .034).

HOW DOES THE MODEL FIT FOR T1 DIABETES MELLITUS.
So why an increased risk of ED in T1DM? •
Daneman et al. (1998) - 3 diabetes-specific aspects that increase risk of ED in people with T1DM:
1.
Weight Gain – increases body dissatisfaction, triggering dieting, bingeing and compensatory purging behaviour. Dietary Restraint in nutritional management of IDDM – may increase salience of eating concerns and its control, triggering eating disturbed behaviour Insulin Misuse – highly effective yet dangerous weight loss strategy at disposal. Strong maintaining factor.

Eating Disturbances in young people with T1DM (Wilson et al., 2014) • N=50 Aged 14-16 (60% female) • Eating disordered attitudes associated with higher BMI-z, poorer glycaemic control, and lower self-esteem. • Eating disordered behaviour associated with lower self-esteem and higher diabetes-related family conflict.
– Glycaemic control and BMI differences did not reach significance (but low incidence of ED behaviours)
• Higher body mass indexes (BMIs) impact on girls more than they do on boys.

Reduced insulin
Dysfunctional Perfectionism Definition: “over-evaluation of the determined pursuit of personally demanding, self-imposed standards, despite adverse circumstances” (Shafran, Cooper & Fairburn, 2002)
• At the core of eating disorders • DP significantly associated with heightened preoccupation with weight (Smith et al., (in press), Pollock-Barziv & Davis, 2005) and dietary restraint (Smith et al., in press) in young people with T1DM
– But, DP NOT associated with eating disturbed behaviours or glycaemic control

Reduced insulin
Disinhibited eating and insulin/glucose management (Merwin et al 2014) • N=276 type 1 diabetes completed an online survey • Hypothesis that disinhibited eating when blood sugar is thought to be low predicts weightrelated insulin mismanagement, and this, in turn, predicts higher HbA1c. • Majority some degree of disinhibition when blood glucose is low (e.g., eating foods they do not typically allow) plus negative affect (e.g., guilt/shame). DM SPECIFIC TARGET FOR TREATMENT
Animals models of binge eating environmental factors • A period of under nutrition. • Divert food stomach • Intermittent availability of highly palatable food • Stress. • Breeding (Rada et al 2005, Lewis et al 2005, Avena et al 2005, Corwin 2006, Corwin & Hajnal 2005, Boggiano et al 2005; Avena & Hoebel 2003, Avena & Hoebel 2007, Boggiano et al 2007).
Animals models of binge eating
(these animals also become addicted to other substances e.g. amphetamine & change in opiate, dopamine receptors. Avena et al 2011, 12)
Animal models of addiction “binge form of administration is key”- rate of change of drug of abuse in brain a key variable. (Kreek 2013,2014). Glucose similar mechanism cocaine (Blum et al., 2014).

Conclusion Factors that increase eating disorder risk in T1DM • Weight gain with insulin treatment (body dissatisfaction) • Dietary restraint and salience of weight and food rules. • Insulin misuse as highly effective purging strategy • Chronic illness can reduce self esteem. • Compulsivity and Impulsivity general risk factors and interact with insulin treatment. • Intermittent sugar rushes (fast/feast) produce plastic changes in the reward and counter reward system develop which lead to food addiction. • Links between family functioning, glycaemic control and treatment adherence

Why do we need to focus on Eating Disorders in T1DM? • Eating disturbances more prevalent in young people with IDDM than those without T1DM – Girls (aged 12-19) with T1DM 2.4x more likely to have ED (EDNOS, BN) than age matched controls (Jones et al., 2000) – Sub-threshold ED - 1.9x – Significantly higher HbA1cs in ED
• High rates of insulin misuse as weight loss strategy • Eating disorder symptoms associated with poorer glycaemic control and greater probability of diabetic complications (Rydall et al., 1997)

Gold standard T1DM and ED service Ethos
Organisation
Clinician
Patient and family
Ethos
Duty of care Can’t pass the buck In for the long haul
• For people with T1DM and ED, the multi disciplinary diabetes team is best placed to manage and support
• No longer acceptable to say ‘its not my problem’ because its ‘up there’ and ‘let the psychiatrists fix it and then get back to me’
• collaboration with the patient • the patient is part of the team • expect relapse remitting course
Organisation Integrated service
• mental health should move into diabetes care as one unit • this is what it is like for the patient • specialist beds in tertiary centres
Segregated services
• parallel services are probably ineffective and more expensive
Clinical processes
Profession and specialty
• mental health professional with knowledge of medical nuances in T1DM and ED • dedicated diabetes professionals who are competent at ED
Skills
• core skills for all diabetes professionals • advanced skills for some diabetes professionals • case managers eg King’s 3DFD model and Cambridge case management model for DKA • family work • adolescence and mental health
Patient Raising awareness
• self help materials • information giving at diagnosis • instruction during structured education
Family support
• carers need information, guidance and sometimes additional skills • family interventions
Schools/workplace
• patient centred liaison with schools and occupational health
Core skills: motivational interviewing Active listening (OARS)
Managing resistance
Directing change
Supporting self efficacy
• Open questions • Affirmation • Reflections • Summaries • selective attention/positive reframing • normalising • collaboration • managing ambivalence • helping patients to recognise their desire, ability and reasons for changing • commitment to change • their belief that they have the ability to self manage
Eliciting the problem using motivational interviewing It seems like you want to have good diabetes control but it has been difficult (with weight changes). Have I understood you correctly? Following rules about eating can sometimes to lead to weight and shape issues that are hard to manage. Have you noticed difficulties like this? Your diabetes is important to you -I can see that -so thank you for coming today-it must be hard juggling diabetes with studies, wanting to be just like your friends Perhaps you are here because your parents want you to come
Advanced skills: CBT techniques Thoughts • Since insulin, I am getting fat • I think /fear I am having a really bad hypo • I hate having diabetes • I am going to get complications/Im going to die • I am a failure/Im not like everyone else • I don’t like this anxious feeling so I will comfort eat instead
Feelings
Behaviours
• I am anxious • I am sad • I am angry • I am irritable
• Reduce/omit insulin (usually fast acting) • Over treat hypo • Forget diabetes equipment

Summary ED in T1DM is a growing problem with little evidence based treatment Interplay of many psychological and medical processes in onset and perpetuation A gold standard model is where mental health is integrated into diabetes services by the range of psychological skills available

London Strategic Clinical Networks
• Eating disorders are more common in adolescent and young adult females with diabetes. • When present, they are associated with: • High frequency of insulin omission • Worse metabolic control • Earlier onset of complications • Higher mortality • Recurrent admissions
Management
• Key thing is probably awareness and recognition – early diagnosis? Screening tools / questionnaires • What is differential diagnosis for recurrent DKA do we consider this properly. • Severe cases need joint ED / diabetes approach • Milder cases need MDT approach within clinics
