OBJECTIVE: To evaluate temporal trends in rates of initial lower extremity amputation (ILEA) among @entity1 with @entity6 in the @entity283 ( @entity283 ). RESEARCH DESIGN AND METHODS: Retrospective administrative data analysis of @entity283 clinic users with @entity6 in fiscal years (FY) 2000 to 2004 (1 October 1999-30 September 2004). We calculated annual age- and sex-standardized rates of initial major, minor, and total amputations for the overall population and for various racial/ethnic groups (African Americans, Hispanics, and whites). Trends in ILEA risk were evaluated with and without adjustment for demographic characteristics and other potential risk factors, including presence of microvascular and @entity66 , and antiglycemic treatment. RESULTS: Study populations of @entity283 @entity1 with @entity6 and without prior amputations ranged from 405,580 in FY 2000 to 739,377 in FY 2004. Age- and sex-standardized ILEA rates decreased by 34% (7.08/1,000 @entity1 in FY 2000 to 4.65/1,000 @entity1 in FY 2005) during the 5-year period. Minor and major amputation rates decreased by 33% (4.59 to 3.06/1,000) and 36% (2.49 to 1.59/1,000), respectively. Of major amputations, below-knee rates decreased from 1.08 to 0.87/1,000 (-19%), and above-knee decreased from 1.41 to 0.72/1,000 (-49%). Similar trends were seen for all racial groups. ILEA risk decreased by 28% (odds ratio 0.72 [95% CI 0.68-0.75]) when FY 2004 was compared with FY 2000 in the model, adjusting for demographic characteristics. This risk decrease was 22% in the model adjusting for all independent variables (odds ratio 0.78 [95% CI 0.74-0.82]). CONCLUSIONS: Downward 5-year trends in ILEA rates were observed for all amputation levels and among all racial groups, even after adjustment for risk differences over time.

Trends in initial lower extremity amputation rates among XXXX health care System users from 2000 to 2004.
