Older People’s Diabetes Network (OPDN)
• 3rd National Conference of OPDN took place on November 13
• Hosted by Aston University
• Led by the network’s Clinical Lead Professor Alan Sinclair
• Sharing good practice and latest developments
Type 2 diabetes – A High Impact Disease in Older People
• 7th highest cause of years lost and 8th highest cause of disability adjusted life years in Western countries: in those aged 60–79 years, HR of death is 1.91 (men) and 2.53 (women)
• Older adults with diabetes have the highest rates of major lower-extremity amputation, myocardial infarction (MI), visual loss, and end-stage renal disease of any age group
• Those aged ≥75 years also have double the rate of emergency department visits for hypoglycaemia than the general population with diabetes
• An ADL restriction increases costs of care 3-fold and admission to a care home increases costs 9-fold!
Kirkman MS et al, Diabetes Care 2012; Weiss Co, 2011; Lubitz J et al,2003
• Retrospective cohort study of 71,092 type 2 diabetes patients aged >60 (mean 71 years) in California
• Showed U-shaped relationship between HbA1c and mortality, consistent across all age groups
• Lowest hazard ratio for mortality was at HbA1c of 7.5%

• Prospective cohort study to explore hypothesis that dependent older people with diabetes (mean age 80y) able to achieve AGS target HbA1c <8% would have less functional decline than those whose HbA1c >8%
• But results showed the opposite!
2013/4 IDF Recommendations based on Functional Category
Considerations
• Need to provide clear guidance on metabolic targets
• Recognition of the complex spectrum of comorbidity and functional impairment in ageing populations
• Recognition of the ‘Vulnerability’ profile of older people with diabetes
• Acceptance that Frailty is a common pre-disability characteristic
Categories CATEGORY 1: FUNCTIONALLY INDEPENDENT
The usual HbA1c target is 7.0-7.5% / 53-59 mmol/mol.
CATEGORY 2: FUNCTIONALLY DEPENDENT
Subcategory A: Frail
The usual HbA1c target is 7.0-8.0% / 53-64 mmol/mol
Subcategory B: Dementia
An HbA1c target up to 8.5% / 70 mmol/mol may be appropriate
CATEGORY 3: END OF LIFE CARE
The glycaemic target is to avoid symptomatic hyperglycaemia

Residents at Great Risk of Harm from Glucose-Lowering Agents – a Freedom of Information Study Milligan F, Krentz AJ, Sinclair AJ Dec 2011 – Diabetic Med
• Aim: To analyse adverse drug events in older people with diabetes in the care home setting via incident reports – Jan 2005 – Dec 2009
• A Freedom of Information request was made to the National Reporting and Learning Service via the National Patient Safety Agency.
• RESULTS: There were 684 reports related to insulin and 84 incidents related to oral glucose-lowering agents. The most common error category with both types of drug therapy was wrong or unclear dose: 173 reports for insulin, including one death, and 20 reports for oral therapy.
• CONCLUSIONS: Residents with diabetes in care homes are potentially at risk of harm from adverse drug events pertaining to insulin and oral glucose-lowering agents.
• Because of likely under-reporting, our data most likely represent only a fraction of events.
Setting the Scene
• How common is diabetes in older populations?
• Any diagnostic issues?
• What is this thing we call ‘Frailty’?
• What are we doing in care home diabetes?
• IDF Global Guidance – why are these recommendations different?

Accelerated Loss of Skeletal Muscle Strength in Older Adults with Type 2 Diabetes Health, Aging, and Body Composition Study
• Arm and leg muscle mass/strength were examined at baseline and at 3 years in 1,840 older adults aged 70–79 years (n=305 with type 2 diabetes)
• Dual energy X-ray absorptiometry and isokinetic and isometric dynamometers used
• Results
No significant differences in arm strength/quality between diabetic and non-diabetic groups
Significant declines in leg muscle mass (p<0.05), muscle strength (p<0.001), and muscle quality (p<0.05) noted in those with diabetes

Co-morbidities, frailty and mortality
Frailty – a definition
• Frailty is a multidimensional geriatric syndrome characterized by increased vulnerability to stressors as a result of reduced capacity of different physiological systems.
• Implications
Associated with an increased risk of adverse health-related outcomes in older persons, including falls, disability, hospitalizations and mortality; also associated with biological abnormalities (e.g. biomarkers of inflammation) regardless of the definition used to assess frailty.

Key objectives: • Effectiveness of multimodal intervention in
subjects aged ≥70 years with T2D
• Effectiveness of an intervention on healthcare expenditure, hypoglycaemic events, incidence of hospital admission or carer burden
• Mechanisms underlying the effect of the intervention (e.g., changes in body composition)
• Efficacy of new therapeutic devices and new ways to measure changes in QoL (substudies)
A randomized clinical trial to evaluate the effectiveness of a multi-modal intervention in older people with Type 2 diabetes on Frailty and Qualify of Life: Phase IIb
Results will be reported in Month 48
The MID-Frail Study
Explaining why Diabetes Care for Residents is Challenging
• Albert Einstein said that if you can't explain something in a simple way then you don't know the subject well enough
• Well let's see:
• Residents of nursing homes are often frail, have multiple medical problems, poly-pharmacy, complex illness, often immobile, cognitively impaired and incontinent, lowered quality of life - so how do I explain this simply? The answer is that when a resident enters a nursing home they are entering a high risk environment where: - there is little medical supervision, no access to specialists, cared for by unqualified and uneducated staff, in essence an end of life care scenario and are likely to die within 24 months usually - is that simple enough?
The 99% rule!
• 99% of all the species ever lived are extinct
• 99% of PowerPoint presentations you never remember (including this one probably! )
• 99% of nursing home residents are dead within 3 years
• (sady) 99% of UK diabetologists never take an active interest in care home diabetes……..
Not certain why this is? • Diabetes is a
highly prevalent in care homes
• Diabetes is often a complicated management problem
• Diabetes increases the risk of hospital admission 6-fold
England-wide Care Home Diabetes Audit
Developing The Audit
• This work stemmed from the recommendations of “Good Clinical Practice Guidelines For Care Home Residents With Diabetes” 2010
• The Audit piloted in Beds & Herts
• Collaboration between 9 key partner organisations
• Over 2000 responses were received from around 9000 homes
Available at: www.diabetesfrail.org
Raising Standards of Diabetes Care -CQC diabetes guidance
• Guidelines to improve the quality of care for people with diabetes living in care homes.
• Series of indicators to help inspectors assess whether a service is meeting needs.
• An assessment and support framework to protect dignity and rights.
CQC Elements of Good Practice – Diabetes 2015
7. What are the elements of good diabetes care?
Good diabetes care begins with a diabetes policy. A good diabetes policy describes and requires the four elements set out below.
1. Diabetes screening on admission that
is recorded and audited.
This can reduce the number of GP call-outs and hospital admissions linked to undiagnosed diabetes and associated complications.
1. Availability of a fully-stocked and
maintained hypoglycaemia kit.
This can reduce ambulance call-outs and hospital admissions due to hypoglycaemia.
1. A risk-calculation and assessment tool
for diabetes foot disease.
Use of such a tool by suitably trained staff can reduce unnecessary amputations.
1. Access to good quality diabetes
education and training for care home
staff.
Good training can lead to fewer GP call-outs and hospital admissions for hypoglycaemia, infections, and other common medical problems associated with diabetes.
Good leadership and management in relation to the care of diabetes includes regular audit and assessment of these elements in practice.
Appendix 1 below sets out a flow chart for assessing diabetes care in care homes.
Summary and Optimism for the Future
• Growing recognition of the unique characteristics of the diabetes state in ageing populations
• The emergence of frailty as a complication of diabetes
• Making progress with diabetes care in care homes – at last!
• New IDF Guidelines that support categorisation based on co-morbidity and functional/dependency level
• Re-emphasis of the need for comprehensive assessment and the delivery of ‘compassionate’ approach by health and social care professionals
