Trends of Nontraumatic Lower Extremity Amputation in End-Stage Renal Disease and Diabetes, U.S. 2000-2014

Abstract

Non-traumatic lower extremity amputation (NLEA) is a complication of end-stage renal disease (ESRD) and diabetes mellitus (DM). Global data suggest hospitalization rates for NLEA among people with DM are declining. Contemporary data from the U.S. and among those with ESRD is lacking. We estimated NLEA hospitalizations during 2000-2014 in adults aged ≥18 years with ESRD and DM (ESRD-DM) and in the broader DM population. We determined NLEA hospitalisations rates (ICD-9 CM procedure codes: 8411-8419, excluding diagnosis codes 895-897) for ESRD-DM using the U.S. Renal Data System and for DM using the U.S. National Health Interview Survey and the National Inpatient Sample. We assessed trends over time using Joinpoint regression. In the ESRD-DM population, age-standardised NLEA rates per 1,000 persons decreased from 61.5 (95% CI: 59.8-63.2) in 2000 to 39.7 (38.4-41.0) in 2014 (Figure). In the DM population, NLEA rates decreased from 10.8 (9.2-12.4) in 2000 to 6.1 (5.1-7.0) in 2009, and then increased to 8.7 (7.7-9.6) by 2014. NLEA rates remained 4.6 times (95% CI: 4.5-4.7) higher in ESRD-DM compared with DM only. Rates of NLEA hospitalisations declined during 2000-2014 in ESRD-DM, while they declined then increased in the population with DM. Increased attention to preventive care among ESRD-DM and DM populations is needed. Disclosure J.L. Harding: None. M.E. Pavkov: None. N. Burrows: None. E.W. Gregg: None. I.A. Hora: None.
