These changes present significant challenges to welfare, pension, and healthcare systems in
both developing and developed nations
 Diabetes-related complications are the major causes of morbidity,
disability and mortality in older patients with type 2 diabetes:
 There is now overwhelming evidence that the level and duration of
glycemia influences the development of diabetes-related
complications

Screening and diagnosis
in the elderly
Recommendations for screening and diagnosis in the
elderly
 Clinical presentation of diabetes in old age is often
asymptomatic and non-specific and clinical diagnosis may
be delayed
 In general, screening for and diagnosis of diabetes in older
subjects should be in accordance with published
international/national criteria and guidelines, and no age
modified criteria are currently recognised
 The prevalence and incidence rates of diabetes mellitus in
elderly subjects (>65 years) may be underestimated when
using only fasting plasma glucose.
Sinclair A, et al. Diabetes & Metabolism. 2011;37:S27-S38.
 The presence of isolated post-challenge
hyperglycaemia (IPH) is common in older
subjects and should alert the clinician to screen
for cardiovascular disease and institute risk
intervention strategies to minimise premature
death.
 In high-risk older subjects with a normal fasting
glucose, and where an OGTT is not feasible,
determination of HbA1c may be helpful in the
diagnosis of diabetes. A value of HbA1c >6.5%
may indicate the likely presence of diabetes
Managing type 2 diabetes in the elderly
Special considerations
 Clinicians who manage older people with diabetes
require special skills if they wish to provide high-
quality care
 Their approach is influenced by a multitude of
factors, such as the higher frequency of medical
comorbidities, frailty and socioeconomic issues
 Comprehensive geriatric assessment is a potentially
important tool in ensuring that patients with
diabetes receive a multi-professional assessment of
their functional status and unmet needs.Sinclair A. Diabetes Spectrum. 2006;19(4):229-33.
Management goals in the elderly
 The overall goals of diabetes management in older adults
are similar to those in younger adults and include
management of both hyperglycaemia and risk factors1
 However, in frail, elderly patients with diabetes, avoidance
of hypoglycaemia, hypotension, and drug interactions due
to poly-pharmacy are of even greater concern than in
younger patients with diabetes1,2.
 In addition, management of coexisting medical conditions
is important because it influences their ability to perform
self-management2

Medical1 Patient oriented1
 Freedom from hyperglycaemic symptoms
 Prevention of undesirable weight loss
 Avoidance of hypoglycaemia and other
adverse drug reactions
 Estimation of cardiovascular risk as part of
screening for and preventing vascular
complications
 Detection of cognitive impairment and
depression and functional disabilities at an
early stage
 Achievement of a normal life expectancy for
patients where possible
 Protect against heart failure, renal
dysfunctions , bone fractures and drug-drug
interactions2
Maintenance of general well-
being
and good quality of life
Acquisition of skills and
knowledge to adapt to lifestyle
changes
Encouragement of diabetes
self-care
Rationale for high-quality diabetes care in the
elderly
Recommendations:
Screening and early diagnosis may prevent progression of undetected
vascular complications
Overall improved metabolic control will reduce cardiovascular risk
Improved screening for maculopathy and cataracts will reduce visual
impairment and blind registrations
An integrated approach to management of peripheral vascular disease
and foot disorders will reduce amputation rate
Sinclair A, et al. Diabetes & Metabolism. 2011;37:S27-S38.
Associated problems affecting management in the
elderly…
 Poor Hepatic Glycogen Reserve:
Decreased stores related to poor nutrition and decreased
appetite.
 Cataract: Both age and DM contribute to its causation
 Neuropathy: Autonomic neuropathy (postural
hypotension, constipation, etc.)
 Neuropathy, atherosclerosis of peripheral vessels and
poor vision makes elderly more prone to foot problems
and contribute to sexual impotence in a large number
of elderly diabetics.

Complications of type 2 diabetes in the elderly
 Hypoglycaemia
 Cardiovascular
 Microvascular (retinopathy/nephropathy)
 Cognitive (dementia)
 Depression
 Falls and fractures
 Peripheral neuropathy
The frail, elderly patient with diabetes
 Older persons with diabetes are at higher risk
than those without diabetes of:
 Vascular death and cancer mortality1
 Functional disability2
 Geriatric syndromes:
 Depression2
 Cognitive impairment2
 Other geriatric syndromes2
 Severe hypoglycaemia2
(when treated with sulphonylureas or insulin)
 Elderly patients with diabetes are at higher risk for hypoglycaemia and also lack
of awareness about hypoglycaemia compared to younger patients2

Why is the elderly diabetic patient
at high risk of hypoglycaemia?
 Defective Counter-regulation or perception of symptoms

• 1-Attention to
hypoglycemic
symptoms may be
reduced by
depression, cognitive
dysfunction or other
chronic conditions.
 2-Many elderly
patients have limited
knowledge about the
symptoms of
hypoglycemia:
knowledge of
diabetes is essential
for symptom
recognition.
WHY?????
1. The effects of ageing on the responses to hypoglycaemia:
 There is defective perception of symptoms in the elderly 1
2. The effects of type 2 diabetes on the responses to hypoglycaemia:
 Glucose counter-regulatory mechanisms may be abnormal in patients
with Typ2 DM: impaired glucagon, growth hormone, cortisol, and perhaps
epinephrine responses during hypoglycaemia could all contribute to a
lack of compensatory increase in glucose production2
3. The effects of type 2 diabetes and ageing on the counter-regulatory
responses to hypoglycaemia:
 Impaired perception of hypoglycemia in older type 2 diabetes patients3
The elderly patient with diabetes is at high risk of
hypoglycemia

Depression among people with diabetes reduces
quality of life and is associated with morbidity and mortality
 It is imperative that clinicians review patients’ depressive
symptoms and that goal setting and future management may
need to involve psychogeriatric input1
Management and treatment
considerations in the elderly patient
with type 2 diabetes

2. Inzucchi SE, et al. Diabetes Care. 2012;55(56):1577-96.
Treatment priority of the elderly: prevention of hypoglycaemia
 The risks of tight glycaemic control may exceed the benefits in many
elderly patients1
 In elderly patients, who are frail and may have comorbidities limiting ability to self-
management, tight glycaemic control is unlikely to benefit...
 … and hypoglycaemia is associated with a wide variety of disabling consequences,
including amputation, peripheral neuropathy, immobility, falls, stroke, and cognitive
change.
 The frequency of hypoglycaemia is high and is exacerbated by older people having
little knowledge about the signs and symptoms of hypoglycaemia.
 The goal of minimising symptomatic hypoglycaemia, short-term geriatric syndromes
and maximising quality of life should be the primary factors in individualising
glycaemic targets
 Glycemic targets for elderly with long-standing or more complicated
disease should be less ambitious than for the younger, healthier
individuals2

Yudkin JS, et al. Diabetologia. 2010;53(10):2079-85.
 The benefits of intensified glucose control require
long-term adherence
 Older patients or those with reduced life expectancy
will therefore experience little benefit
 Recent studies, which have used modelling
techniques to estimate the impact of glycaemic
control on life expectancy are enlightening in this
respect. The UKPDS outcomes model estimated that
intensified glucose control would increase quality-
adjusted life years (QALY) by 0.27, or about 99
days.
Treatment priority of the elderly: prevention
of hypoglycaemia
 The elderly patient with diabetes is often a frail patient1
 Elderly people with diabetes are also at higher risk for
hypoglycaemia and hypoglycaemia unawareness1,2
 Hypoglycaemia is associated with many adverse
consequences1
 The available data suggest that the risks of tight glycaemic
control (and the greatest risk is hypoglycaemia) exceed the
benefits in many elderly patients1

2. ADA Diabetes Care;2012:35(1):S11-S63
EASD/ADA recommendations for managing
hyperglycaemia in the elderly (2012)
 Glycaemic targets for elderly with long-standing or more complicated
disease should be less ambitious than for younger, healthier
individuals
 If lower targets cannot be achieved with simple interventions, an
HbA1c of <7.5–8.0% may be acceptable, transitioning upward as age
increases and capacity for self-care, cognitive, psychological and
economic status, and support systems decline
 In the aged, the choice of anti-hyperglycaemic agent should focus on
drug safety, especially protecting against hypoglycaemia, heart
failure, renal dysfunction, bone fractures, and drug–drug interactions.
Strategies specifically minimising the risk of low blood glucose may
be preferred

Diabetes in the Elderly Checklist
ASSESS for level of functional dependency (frailty)
INDIVIDUALIZE glycemic targets based on the above (A1C
≤8.5% for frail elderly) but if otherwise healthy, use the same
targets as younger people
AVOID hypoglycemia in cognitive impairment
SELECT antihyperglycemic therapy carefully
Caution with sulfonylureas or thiazolidinediones
Basal analogues instead of NPH or human 30/70 insulin
Premixed insulins instead of mixing insulins separately
GIVE regular diets instead of “diabetic diets” or nutritional
formulas in nursing homes.
Canadian D A Guidelines 2015
2015
In the frail elderly, while avoiding symptomatic
hyperglycemia, glycemic targets should be an A1C of
≤8.5% and FPG or pre-prandial PG of
5.0-12.0 mmol/L, depending on the level of frailty.
In elderly people with cognitive impairment, strategies
should be employed to strictly avoid hypoglycemia,
which include the choice of antihyperglycemic
therapy and less stringent A1C target [Grade D, Consensus].
Elderly people with type 2 diabetes should perform
aerobic exercise and/or resistance training, if not

 Advancing age is a risk factor for the development of diabetes1
 Elderly onset diabetes should be diagnosed as early as possible in
accordance with national guidelines to avoid the progression of
vascular complications, retinopathy and renal impairment2
 Hypoglycaemia is a danger in elderly diabetes patients due to a
higher level of hypoglycaemic unawareness and medication
combinations in this population3
 The presence of comorbidities presents unique challenges for the
management of elderly type 2 diabetes patients3
 Cognitive dysfunction, depression, risk of falls, frailty and other
morbidities need to be addressed as part of comprehensive care3

    Age at diagnosis The peak age at diagnosis is between 40 and 55, with a sharp decline after age 65. Among elderly patients with diagnosed diabetes, the majority of diabetes is diagnosed in middle-age (aged 40-64 years) and a minority diagnosed at age ≥65 years. 1. Selvin E, et al.

    Recommendations for screeningand diagnosis in the elderly  Clinical presentation of diabetes in old age is often asymptomatic and non-specific and clinical diagnosis may be delayed  In general, screening for and diagnosis of diabetes in older subjects should be in accordance with published international/national criteria and guidelines, and no age modified criteria are currently recognised  The prevalence and incidence rates of diabetes mellitus in elderly subjects (>65 years) may be underestimated when using only fasting plasma glucose. Sinclair A, et al. Diabetes & Metabolism. 2011;37:S27-S38.
  • 13.
     The presenceof isolated post-challenge hyperglycaemia (IPH) is common in older subjects and should alert the clinician to screen for cardiovascular disease and institute risk intervention strategies to minimise premature death.  In high-risk older subjects with a normal fasting glucose, and where an OGTT is not feasible, determination of HbA1c may be helpful in the diagnosis of diabetes. A value of HbA1c >6.5% may indicate the likely presence of diabetes

    Managing type 2diabetes in the elderly Special considerations  Clinicians who manage older people with diabetes require special skills if they wish to provide high- quality care  Their approach is influenced by a multitude of factors, such as the higher frequency of medical comorbidities, frailty and socioeconomic issues  Comprehensive geriatric assessment is a potentially important tool in ensuring that patients with diabetes receive a multi-professional assessment of their functional status and unmet needs.Sinclair A. Diabetes Spectrum. 2006;19(4):229-33.
  • 15.
    Management goals inthe elderly  The overall goals of diabetes management in older adults are similar to those in younger adults and include management of both hyperglycaemia and risk factors1  However, in frail, elderly patients with diabetes, avoidance of hypoglycaemia, hypotension, and drug interactions due to poly-pharmacy are of even greater concern than in younger patients with diabetes1,2.  In addition, management of coexisting medical conditions is important because it influences their ability to perform self-management2 1.Brown AF, 2003; 51(5):S265-286. 2.Sinclair A. Diabetes Spectrum. 2006;19(4):229-33.

Medical1 Patient oriented1  Freedom from hyperglycaemic symptoms  Prevention of undesirable weight loss  Avoidance of hypoglycaemia and other adverse drug reactions  Estimation of cardiovascular risk as part of screening for and preventing vascular complications  Detection of cognitive impairment and depression and functional disabilities at an early stage  Achievement of a normal life expectancy for patients where possible  Protect against heart failure, renal dysfunctions , bone fractures and drug-drug interactions2 Maintenance of general well- being and good quality of life Acquisition of skills and knowledge to adapt to lifestyle changes Encouragement of diabetes self-care
  • 17.
    Rationale for high-qualitydiabetes care in the elderly Recommendations: Screening and early diagnosis may prevent progression of undetected vascular complications Overall improved metabolic control will reduce cardiovascular risk Improved screening for maculopathy and cataracts will reduce visual impairment and blind registrations An integrated approach to management of peripheral vascular disease and foot disorders will reduce amputation rate Sinclair A, et al. Diabetes & Metabolism. 2011;37:S27-S38.
  • 18.
    Associated problems affectingmanagement in the elderly…  Poor Hepatic Glycogen Reserve: Decreased stores related to poor nutrition and decreased appetite.  Cataract: Both age and DM contribute to its causation  Neuropathy: Autonomic neuropathy (postural hypotension, constipation, etc.)  Neuropathy, atherosclerosis of peripheral vessels and poor vision makes elderly more prone to foot problems and contribute to sexual impotence in a large number of elderly diabetics.

    1. The effectsof ageing on the responses to hypoglycaemia:  There is defective perception of symptoms in the elderly 1 2. The effects of type 2 diabetes on the responses to hypoglycaemia:  Glucose counter-regulatory mechanisms may be abnormal in patients with Typ2 DM: impaired glucagon, growth hormone, cortisol, and perhaps epinephrine responses during hypoglycaemia could all contribute to a lack of compensatory increase in glucose production2 3. The effects of type 2 diabetes and ageing on the counter-regulatory responses to hypoglycaemia:  Impaired perception of hypoglycemia in older type 2 diabetes patients3 The elderly patient with diabetes is at high risk of hypoglycemia 1.

     The benefitsof intensified glucose control require long-term adherence  Older patients or those with reduced life expectancy will therefore experience little benefit  Recent studies, which have used modelling techniques to estimate the impact of glycaemic control on life expectancy are enlightening in this respect. The UKPDS outcomes model estimated that intensified glucose control would increase quality- adjusted life years (QALY) by 0.27, or about 99 days.

    EASD/ADA recommendations formanaging hyperglycaemia in the elderly (2012)  Glycaemic targets for elderly with long-standing or more complicated disease should be less ambitious than for younger, healthier individuals  If lower targets cannot be achieved with simple interventions, an HbA1c of <7.5–8.0% may be acceptable, transitioning upward as age increases and capacity for self-care, cognitive, psychological and economic status, and support systems decline  In the aged, the choice of anti-hyperglycaemic agent should focus on drug safety, especially protecting against hypoglycaemia, heart failure, renal dysfunction, bone fractures, and drug–drug interactions. Strategies specifically minimising the risk of low blood glucose may be preferred Inzucchi SE, et al. Diabetes Care. 2012;55(56):1577-96.
