Abstract

To describe trends in the incidence and outcomes of lower-extremity amputations (LEAs) in patients with T1DM and T2DM in Spain, 2001-2012. We used national hospital discharge data. Incidence of discharges attributed to LEA procedures were calculated stratified by diabetes status and type of LEA. Joinpoint log-linear regression for incidence trends and logistic regression for factors associated with in-hospital mortality were used. From 2001 to 2012, 73,302 minor LEAs and 64,710 major LEAs were performed. We found that incidence of minor LEA procedures in T1DM patients decreased by 9.84% per year from 2001 to 2008 and then remained stable through 2012. In T2DM patients, LEA increased by 1.89% per year over the entire study period. Among patients with T1DM, major LEA incidence rate decreased by 10.5% from 2001 to 2012. In patients with T2DM, it increased by 4.29% from 2001 to 2004, and then decreased by 1.85% through 2012. In-hospital mortality after major or minor LEAs was associated with older age in all groups and with being female in T2DM and in people without diabetes. Our national data show a decrease in the incidence of minor LEAs in patients with diabetes and in major LEAS in patients with T1DM over the period of study. In patients with T2DM, we found a decrease between 2004 and 2012. An additional improvement in preventive care, such as the introduction of diabetes foot units in hospitals, is necessary.
