Impact of malnutrition and frailty on mortality and major amputation in patients with CLTI
Objectives To understand the prevalence of malnutrition and its association with chronic limb‐threatening ischemia (CLTI) outcomes; to clarify the differential impact of revascularization methods on outcomes; to assess the ability of the CLTI Frailty Risk Score (CLTI‐FRS) to predict adverse events i...

Zusammenfassung: | Objectives
To understand the prevalence of malnutrition and its association with chronic limb‐threatening ischemia (CLTI) outcomes; to clarify the differential impact of revascularization methods on outcomes; to assess the ability of the CLTI Frailty Risk Score (CLTI‐FRS) to predict adverse events in patients hospitalized with CLTI.
Background
Despite advances in the management of CLTI, a majority still undergo major amputation, and a minority heal within 6 months. There is a lack of validated assessment tools for the identification and management of frailty and malnutrition in these patients.
Methods
Using the National Inpatient Sample from January 2012 to September 2015, we identified all patients with CLTI using International Classification of Diseases Ninth Edition Clinical Modification codes. The cohort was divided into three groups according to nutritional status. Multivariable regression analysis was used to analyze the interaction between malnutrition and outcomes of interest.
Results
Of 1,414,080 CLTI‐related hospitalizations, 163,835 (11.6%) were malnourished, 332,855 (23.5%) patients were frail, 917,390 (64.9%) were well‐nourished. In‐hospital mortality, major amputation, the average length of stay, and hospital costs were highest among malnourished or frail patients and lowest in well‐nourished patients (p |
