1 Every 30 seconds, a lower limb is lost to diabetes somewhere in the world นำเสนอโดยนพ.เพชร รอดอารีย์ ประชุมเรื่องเบาหวานกับการดูแลเท้า ณ โรงแรมมารวยกาเด็นท์ กรุงเทพมหานคร วันที่ 21 พ.ย. 2548
2 Diabetes Complication in the Thailand Diabetes Registry From 9414 subjects register in the project, we find that they have more common microvascular complication that the macrovascular diseases. This is probably due to method of diagnosis. The CVD is an symptomatic and have overt clinical diseases, whereas the microvascular disease in mostly in the early stage because we use screening test such as urine microalubumin as a diagnostic tool.But this information telling us that we will facing huge number of retinopathy and renal disease in very near future if we do nothing in term of preventive measurement.

But we found that 3.9% had absence of pulse and 1.5% had been amputated. But luckily most of them is only toe amputation, and only 4% undergone above knee amputation.

In and PAD epidemiologic study using ABI as a screening test test for PAD in diabetic patient age over 50 with another one risk factor for atherosclerotic disesae. We found that Thailand have anormal ABI less that 0.9 about 15 % which is again in an average of other asian countries.CountriesPAD Epidemiologic study (PAD-SEARCH)

14 Questions Question 1: Any change in the foot since the last evaluation Question 2: Does the patient have a foot ulcer now or a history of foot ulcer?Question 3: Is there pain in the calf muscles when walking--i.e., pain occurring in the calf or thigh when walking less than one block that is relieved by rest?

16 Sensory Foot ExamThe sensory exam should be done in a quiet and relaxed settingApply sufficient force to cause the filament to bendThe total duration of the approach approximately 1-2 seconds
17 Risk Categorization Risk Category Definition Management Guidelines High RiskOne or more of the following:Loss of protective sensationAbsent pedal pulsesSevere foot deformityHistory of foot ulcerPrior amputationConduct foot assessment every 3 months.Demonstrate preventive self-care of the feet.Refer to specialists and a diabetes educator as indicated. (Always refer to a specialist if Charcot joints are suspected.)Assess/prescribe appropriate footwear.Certify Medicare patients for therapeutic shoe benefits.Place "High Risk Feet" sticker on medical record.
18 Risk Categorization Risk Category Definition Management Guidelines Low RiskNone of the five high risk characteristics below.Conduct an annual foot screening exam.Assess/recommend appropriate footwear.Provide patient education for preventive self-care.
19 Management Plan patient education, any diagnostic studies, footwear recommendations,referrals,follow-up care.
