BACKGROUND
The aims of this study are to compare the diabetes-related lower extremity amputation (LEA) rate trend in South Carolina (SC) to that of the United States (US) and to determine changes in LEA rates in SC according to age, race, gender, and amputation
METHODS
National Hospital Discharge Survey (NHDS) and SC hospital discharge data for 1996 to 2002 were analyzed. ICD-9-CM codes identified all diabetic patients and occurrences of LEA. Linear regression was used to compare the LEA rate trends between SC and the US.
RESULTS
LEA rates are decreasing throughout the study period. The slope is greater in SC compared with US (US slope = -0.00082; SC slope = -0.0015; P = 0.002), signifying a decrease in LEA rates of 1.5/1000 per year in SC and 0.8/1000 per year in the US. Furthermore, LEA rate decreases in SC are significant throughout all ages, races, genders, and amputation levels.
CONCLUSIONS
Diabetes-related LEA rates are decreasing in SC more rapidly than in the US. Ongoing community-level education may be assisting in the favorable trends.
背景
本研究旨在比较南卡罗来纳州（SC）与美国（US）糖尿病相关下肢截肢（LEA）率的趋势，并根据年龄、种族、性别和截肢情况确定SC州LEA率的变化。
方法
分析了1996年至2002年的国家医院出院调查（NHDS）和SC州医院出院数据。ICD-9-CM编码确定了所有糖尿病患者和LEA的发生情况。采用线性回归比较SC州和美国之间的LEA率趋势。
结果
在整个研究期间，LEA率呈下降趋势。SC州的斜率大于美国（美国斜率=-0.00082；SC州斜率=-0.0015；P=0.002），这表明SC州LEA率每年下降1.5/1000，美国每年下降0.8/1000。此外，SC州所有年龄、种族、性别和截肢水平的LEA率下降均显著。
结论
SC州糖尿病相关LEA率的下降速度比美国更快。持续的社区层面教育可能有助于形成这种有利趋势。
