IntroductionChronic limb threatening ischemia (CLTI) morbidity and mortality rates have historically been higher, however recent trends have not been reported. In patients admitted with CLTI, we aimed to examine trends in in-hospital mortality, major amputations, length of stay, and cost of admissions overall, and stratified by type of revascularization procedures. HypothesisWe hypothesized there would be an increase in CLTI-related admissions, with outcomes only marginally improving. MethodsUsing 2011-2017 National Inpatient Sample data, we identified CLTI-related admissions based on ICD-9 and 10-CM codes. We stratified outcomes based on endovascular or open surgical interventions. We also performed multivariable regression analyses based on age, sex, race, hospital size, type and location. ResultsWe identified 2,643,087 CLI-related admissions between 2011 and 2017. CLI admissions increased from 0.9% to 1.4% Ptrend
