    Abstract: Background: Patients with peripheral artery disease (PAD) and diabetes are at increased risk for nontraumatic amputations. The associations of race with amputation risk among patients with both PAD and diabetes is not well understood in recent national patient cohorts. Methods: Using data from the Centers for Medicare and Medicaid Services from 2007-2016, we identified a cohort of patients concurrently diagnosed with both PAD and diabetes (N= 10,506,254). Patients were followed from time of diagnosis to identify major and minor amputation events, and stratified by race (Black, White, Hispanic) in order to determine differences in outcomes. We examined associations between the regional prevalence of PAD and diabetes and amputation rates, at the level of the state and the hospital referral region (HRR). Results: The average rate of amputation between 2007 and 2016 was 0.3 amputations per 1000 Medicare patients. When analyzed by race, Black patients had an almost 3-fold higher rate of amputation as compared to White patients (0.89 v 0.36 per 1000 patients, P 〈 0.001) and a 2-fold higher rate as compared to Hispanic patients (0.89 v 0.39 per 1000 patients, P 〈 0.001). States with larger populations of Black patients with diabetes and PAD had higher rates of amputation. We also observed a direct and significant association between regional prevalence of PAD and diabetes and amputation risk for both White and Black patients (R 2 =0.36 and 0.25 respectively); some states such as Mississippi had disproportionately higher amputations rates among Black patients for a given prevalence of PAD and diabetes (Figure 1). Conclusion: Black patients with PAD and diabetes are at disproportionally higher risk for amputation. Moreover, regional prevalence of concomitant PAD and diabetes is closely related to amputation risk across races.

    Abstract P363: Regional And Racial Variation In The Prevalence Of Concomitant Diabetes And Peripheral Artery Disease

    Abstract: Introduction and Objectives: Prior research has demonstrated regional and racial variation in the prevalence of concomitant diabetes and peripheral artery disease (PAD). However, trends in prevalence of diabetes and PAD across races has not been well explored in recent patient cohorts. Methods: Using data from the Centers for Medicare and Medicaid Services from 2003-2016, we identified patients concurrently diagnosed with both diabetes and PAD (n=10,506,254). Overall prevalence of concomitant diabetes and PAD was determined. Regional variation at the state and hospital referral region (HRR) level was then identified using zip code data. Racial demographics within Medicare data were used to stratify prevalence by race. Results: The overall prevalence of diabetes and PAD across the entire cohort was 15.3 per 1,000 Medicare patients. When stratified by HRR, prevalence of patients with concomitant diabetes and PAD varied by nearly 7-fold with a low of 5.0 and a high of 33.2 per 1,000 Medicare patients. When stratified by race, the number of new patients concomitantly diagnosed with diabetes and PAD decreased across all races, with the greatest decline seen in the Hispanic population (absolute decrease 1.84%, relative reduction 63%). The number of new black patients decreased as well (absolute decrease 1.40%, relative reduction 52%), but blacks continue to comprise the highest proportion of newly diagnosed patients at 1.29% (Figure 1). Conclusion: Significant regional and racial variation exists in the prevalence of concomitant diabetes and PAD diagnoses among Medicare patients with black patients remaining disproportionately affected. Efforts to improve prevention and care management should target these endemic regions and populations.
