  ABSTRACT: To investigate the differences on the diabetic foot problems and its risk factors in south and north of China. Patients with foot problems were surveyed from January 1 to December 31, 2004 in 14 teaching hospitals located in different cities in China, including demographic data, present and past history of the foot problems and peripheral artery disease (PAD), the classification of the foot ulcers based on the Wagner' system, control of the hyperglycemia and lipids disorder, medical cost in hospital and the diabetic complications. All the patients were divided into two groups due to their geographical data, south and north. There were 285 and 349 patients for the group south and group north. No significant differences were found for duration of diabetes or foot problems, fasting or post-meal glucose, total cholesterol, triglycerides, HDL-C, and the numbers of patients with smoke, hypertension, nephropathy or neuropathy between the two groups. There were significant differences for the age (70 yrs vs 66 yrs), percentage of the patients with average person income with over RMB 1000 per month (57.7% vs 45.6%), coronary heart disease (42.6% vs 61.0%) and retinopathy (35.7% vs 49.5%), HbA1c (7.90% vs 8.80 %), LDL-C (2.75 mmol/L vs 2.98 mmol/L), WBC (6.70 x 10(9) vs 7.40 x 10(9)/L), HCT (0.37 vs 0.38), creatinine (87 micromol/L vs 76 micromol/L) and uric acid (333 mmol/L vs 271 mmol/L), and amputation rate (2.6% vs 9.7%) between south and north groups. Logistic analysis showed that severity of the foot problems was associated with ABI and WBC in south group, and with ABI, PLT and HCT in north group. Diabetic foot problems were more severe, with more risk factors and with more medical cost in north patients.

  ABSTRACT: To investigate the medical cost of diabetic patients with foot problems and peripheral artery disease. Type 2 diabetic patients with foot problems admitted into the endocrinology departments of 14 teaching hospitals from Jan. 1 to Dec. 31, 2004 were surveyed for their type and phase of foot ulcers, diabetic complications, medical cost and general personal characteristics. The average medical cost of the hospitalization of these patients was RMB yen 14,906 +/- 7072 (about US $ 1640 +/- 873); medication and examination cost was separately 56% and 19% of the total cost. There was obviously higher medical cost for these patients with longer diabetes duration of over 20 years and with the occupation of laborer and retired worker. Patients with kidney disease had significantly higher medical cost than those without (RMB yen 11 690.7 vs yen 9493.0; P = 0.0013), even if the hospital stay was nearly the same (21 days vs 20 days). The medical cost increase with the severity of diabetic foot problems based on the classification of Wagner System or Texas System. Patients with infection, ischemic foot and gangrene foot stayed in the hospitals longer and had much higher medical cost. The medical cost is higher for diabetic patients with foot problems and is related with the presence of complicating kidney disease, infection and ischemia as well as the severity of foot ulcers.

  ABSTRACT: To investigate the characteristics of diabetic foot with neuropathy and its related factors. 530 out- and in-patients in 14 grade A class 3 comprehensive hospitals in China with foot problems were surveyed. 337 of the 500 patients (63.58%) suffered from neuropathy, 172 (32.45%) with diabetic foot with simple neuropathy and 165 (31.13%) with simple neuropathy combined with peripheral artery disease (PAD). 193 of the 500 patients (36.42%) suffered from peripheral artery disease (PAD). 77.7% of ulcer were caused by physical factors. Questionnaire survey was conducted to collect the demographic data, present and past history, history of the hyperglycemia and lipid disorders, classification and phases of the foot ulcers based on Wagner' system and Texas system, characteristics of neuropathy and other diabetic complications, and relative risk factors. Detailed physical examination was performed, including 10 g nylon filament sensation examination. The duration of diabetic foot of the patients with simple neuropathy was 3 (1, 60) months, significantly shorter than that of the diabetic foot patients with PAD [5 (1, 96) months, P < 0.001]. The Wagner degree of ulcer was related to the duration of diabetes, economic income, foot deformity, nerve reflection, diapason vibration sensation of foot, sensation point of 10 g nylon filament, ankle/brachial index (ABI), foot artery pulse, fasting blood sugar (FBS) and glycated hemoglobin (HbA1c). Stepwise regression analysis revealed that ABI of left posterior tibial artery, vibration detection threshold and economic income were the most significant influencing factors of the degree of ulcer. Neuropathy ulcer is common in diabetic foot patients. The prognosis of healing in diabetic foot with neuropathy is prior to that of diabetic foot with PAD. The neuropathy and PAD of foot influence each other and aggravate the condition of diabetic foot. The examinations of diapason vibration sensation of foot, sensation point of 10 g nylon filament, and Achilles tendon reflex are simple and practical, and are worth recommending.
