A Hospital-Based Survey of Risk Factors for Diabetic Foot Ulceration in Northern Thailand

Ulceration of the foot is found more commonly in patients with diabetes mellitus than those without it. Foot ulcers affect the lives of patients in many ways, and though good care can be defined, loss of limb is a common occurrence in this patient group. Therefore, early detection of the foot at risk for foot ulceration is of paramount importance. Many risk factors for this type of ulcer have been previously reported such as neuropathy, deformity of the foot, arterial occlusion, and poor glycemic control. The authors conducted a hospital-based survey in patients attending a hospital diabetic clinic to establish a baseline database and found that the percentages of sensory neuropathy, history of claudication and poor glycemic control were 19.2%, 5.7%, and 79.7%, respectively. This suggests the need to establish good diabetic control and health education for our patient population.
