BackgroundDiabetic foot amputation is a public health challenge due to the increasing prevalence of type 2 diabetes mellitus (T2D). Although there are many health indicators aimed at the management and control of T2D and its complications, amputations persist.AimTo evaluate the association between diabetic foot amputation index and indicators of care and management of T2D in primary care centers of the eastern section of Santiago, Chile.Material And MethodsWe conducted a mixed ecological study and included information from the Monthly Statistical report of different public health centers from 2014 to 2018. We also analyzed the hospital discharge records from an individual tertiary public health center. The annual index for diabetic foot amputation per 100,000 diabetic patients was used as a response variable. The diabetic compensation percentage was calculated as the proportion of adults with a glycosylated hemoglobin below 7% or the proportion of older people with a value below 8%. The diabetic decompensation percentage was calculated as the proportion of people with a glycosylated hemoglobin over 9%.ResultsA high variability in demographic and management indicators was observed between communes and centers in the study period. Bivariate analysis showed a significant correlation between the amputation index, decompensation, and insulin use. In a regression analysis, the amputation index was significantly associated with the diabetic compensation percentage (β = -3.5; p < 0.05) and a high decompensation percentage (β = 12.3; p < 0.005).ConclusionsThe diabetic foot amputation index was associated with diabetic compensation and decompensation indicators.
