‘Global diabetes tsunami ’ Adult population with
diabetes: About 5% in Europe 10-12% in Asia 30-40% in Pacific Island nation

DIABETES IN MALAYSIA
1.6 Million Malaysian Adults May Have Diabetes
PUTRAJAYA, Aug 11,2009 (Bernama) -- It is estimated that one out of eight Malaysians aged 30 years and above has diabetes, which amounts to over 1.6 million adults, based on the Third National Health and Morbidity Survey (NHMS) 2006.Director-General of Health Tan Sri Dr Mohd Ismail Merican said the prevalence of diabetes also showed a drastic increase of 80 per cent over a period of just 10 years, from 8.3 per cent in 1996 to 14.9 per cent in 2006 for the same age group.Even more worrying, he said, was that one third of those who had diabetes were undiagnosed, and were not aware of their condition.
PREVALENCE OF DM IN MALAYSIA NHMS I (1986) : 6.3%
NHMS II (1996) : 8.3%
NHMS III (2006) : 14.9% (1.6 m)
Now: > 20% (2 million)!!
(WHO- 2.48 million by 2030)

Skin and feet-----> ulcers and Skin and feet-----> ulcers and infectioninfection
Foot ulceration is one of the most common complications in patients with diabetes.
The most common cause of admission to hospital for people with diabetes.
Shorten life expectance and increased mortality
Facts about diabetic foot Facts about diabetic foot ulcerulcer Diabetic ulcer account for 85% of non-traumatic lower extremity amputation.
Diabetic patients is 15x more likely to undergo lower extremity amputation.
3%-4% of diabetes patients have foot ulcer or deep infection at any time.
12% - 24% of diabetes patients with foot ulcer require amputation.
3 -5 year risk of needing contra-lateral amputation is 50%
Estimated every 30 (20) seconds a lower limb is lost to diabetes.
3 -5 year risk of needing contra-lateral amputation is 50%
• 69% of diabetic amputees will not survive past five years (2004).
MALAYSIA- ESTIMATED:
48,000 to 64,000 of patients with diabetic foot ulcer (3% - 4%) at any time???
4,800 to 6,400 amputation (10% of foot ulcer patients require amputation)???
DIABETIC FOOT-MALAYSIAN SCENARIO
Observations- patients: Late presentation
Time for decision making
Bad general condition on admission (septicemia, severely dehydrated, anaemia, cardiac, electrolytes imbalance, DM not controlled, etc).
Alternative treatment
Refusal for treatment (AOR)
Healthcare providers:Primary health-careTertiary health-care
Observations- healthcare providers
Knowledge DM and foot care (NorAziana; Nur Azlina 2009)- 30-40% average to low; dressing materials
Attitude- not serious and aggressive enough (DM control)
Misleading- Diabetic treatment, direct selling etc
Health-care system No dedicated diabetic foot-care team
(not glamorous work)
Not many – interested (junior doctors)
Lack of expert in various fields (vascular, endocrine, podiatric, prosthetic and orthotic)
Lack of facilities (angio etc).
Low priority- OT Wound-care in primary health (dressing,
etc)

Centers for Disease Control and Prevention - USUnited States
1995: the cost to treat a DFU over a 2-year period was $27,987
2009: $46,841
Direct costs for a treating lower-extremity amputation: $22,700 to $51,300 (USD)
2001: the estimated total cost of Rx of diabetic foot ulceration and amputation: $10.9b
2007: total cost of diabetic care $174 billion: $116 billion in direct costs and $58.3 billion in indirect costs (transportation, time etc).
70% of cost due to hospitalization
Economic burdenEconomic burdenSweden (1998): Total direct costs for healing of
infected ulcers not requiring amputation are approximately $17,500 USD
Total costs for lower-extremity amputations are approximately $30,000-$33,500 USD depending on the level of amputation
Financial costs
10 per cent of the NHS budget; around £9 billion a year based on 2007/2008 budget.– £173 million a week– £25 million a day– £1 million an hour– £17,000 a minute– £286 a second.

PATHOGENESIS OF DFP
* Incidence based on Nather, Clarabelle et al 2005
NEUROPATHY (30 – 50% with DM > 10 yrs)
• Major factor in diabetics leading to diabetic foot problems Sensory Autonomic Motor
•Root CauseRoot Cause of all of all diabetic foot diabetic foot problemsproblems
IMMUNOPATHY• Diabetics have inherent susceptibility to infection
• Defects in leukocyte function
leukocyte phagocytosis neutrophil dysfunction deficient white cell chemotaxis and adherence
VASCULOPATHY (6% to 23%)
• Microangiopathy Involving terminal arterioles (thickening of basement membrane of endothelium)
• Atherosclerosis Involving large and medium sized vessels Usually Crural Involvement Pattern - Anterior and
Posterior Tibial vessels in the leg. Dorsalis Pedis and Posterior Tibial vessels in the foot are usually patent (Pomposelli, 1995)
In Singapore, incidence of vasculopathy is in 46.8% based clinically on absence of pulses.
ABI < 0.8 is 31% using Doppler ultra sound probe(Adriaan, Nather et. al., 2005)
FOOT AT RISK-
need periodic, thorough examination.
FOOT AT RISK1. History of ulceration
FOOT AT RISK 2. Presence of Peripheral vascular disease
FOOT AT RISK 3. Presence of Neuropathy
FOOT AT RISK 4. Presence of Deformity
FOOT AT RISK 5. Inappropriate or No Footwear A B
C D
E F
•Over 70% of patients wear slippers or no footwear most of the time (Kathryn, Nather, Zameer A et. al., 2005)
FOOT AT RISK:6. Skin Lesions
• Corn/Callus• Fungal Infection
FOOT AT RISK:7. Nail Pathology
• Deformed Nail• Lesions – Ingrowing Toenail• Infected Nail
General Risk Factors:
• Smoking
• Alcoholism
• Obesity
General Risk Factors: CO-MORBIDITIES• Hypertension
• Hyperlipidemia
• Ischaemic Heart Disease
• Cerebrovascular Accident
GENERAL RISK:
Occupation: Wet at work Prolonged walking or
standing.
Duration of diabetes
Education level
Management Surgical drainage/ debridement
(repeated) - surgical, chemicals, ultrasonic, pulse jets
Dressing (materials and solutions).
Correction of deformity Off-loading amputation Rational use of antibiotics
(appropriate sample for culture; follow up on the laboratory result)
Our roles?
Diabetes and diabetic foot care
Make the diabetic patient/family members aware through continual education, self responsibility and self care that---->
it is possible to lead a normal life through healthy lifestyle, diet, exercises and control of blood sugar and care of the feet
Health education Continuous and tirelessly About diabetes and its complications Important of good diabetic control (role
model) About foot-care How to recognised foot at risk/ trouble.
His/her responsibility for lifelong care of diabetes and feet Important: they must comply
FOOT CARE1. Daily foot
inspection
FOOT CARE
2. Use lukewarm (not hot!) water to wash feet
3. Be gentle feet washing/bathing.
FOOT CARE4. Moisturize feet – be careful with the web space .
5. Nail cutting
6. Wear clean, dry socks (NEVER use heating pad or hot water
bottle)- keep foot warm
FOOT CARE
7. Avoid walk barefoot.
8.Comfortable well fitting shoe
8.Shake out shoes and feel the inside before wearing
8.Never treat corns or calluses themselves.
FOOT CARE11. Diabetic control
12. Stop smoking
13. Periodic foot examination
14. Keep the blood flowing to feet (ELEVATE, WIGGERS TOES, MOVING ANKLE) , avoid cross-leg or hanging leg/feet too long
PREVENTION BETTER THAN
CURE
Surgical procedures:
Prevent recurrent foot ulcer
Reduced / avoid amputation
Improved function
THEME FOR DIABETES 2011:
“Leg for Life”
SHARED RESPONSIBILITY!!
