Abstract
Background and purpose In the city of Trondheim, Norway, diabetic lower-limb amputations accounted for one-third of all lower-limb amputations (LLAs). In an attempt to reduce this rate, a diabetic foot team was established in 1996. We present the incidence of LLA in Trondheim as measured 10 years later.
Patients and methods In 2004–07, we registered all LLAs performed in Trondheim and then compared the data with previously published data from 1994–1997. From 1996 through 2006, we registered the activity of the diabetic foot team and we also registered the number of vascular procedures performed on citizens of Trondheim from 1998 through 2006.
Results Comparing the two 3-year periods 1994–97 and 2004–07, we observed a decrease in all non-traumatic LLAs. The incidence of diabetic major LLAs per 103 diabetics per year decreased from 4.0 to 2.4, and in patients with peripheral vascular disease we observed a decrease in LLAs from 18 to 12 per 105 inhabitants per year. 5,915 consultations on diabetic subjects were conducted by the diabetic foot team during the period 1996–2006. From 1998 to 2006, the rate of vascular procedures decreased in the non-diabetic population, and was unchanged in diabetic subjects.
Interpretation In the population of Trondheim city there appears to have been a reduction in the rate of vascular obstructive lower-limb disease between the two 3-year periods 1994–97 and 2004–07. In our judgment, the decline in diabetic LLA also reflects better care of the diabetic foot.
