Barthel Index and Outcome of Open Bypass for Critical Limb Ischemia.

BACKGROUND
Daily activity should be an important factor to consider when deciding on a treatment strategy for critical limb ischemia (CLI), and we hypothesized that there was a close relationship between activities of daily living (ADL) and prognosis. The aim of this study was to investigate the association between ADL and outcomes of open bypass for CLI.Methods and Results:A total of 226 patients undergoing infrainguinal bypass for CLI between January 2005 and December 2015 were reviewed. They were divided into 2 groups based on Barthel index (BI) at admission (pre-BI; ≥60 and <60) and compared with respect to the incidence of early adverse events and 3-year overall survival and amputation-free survival. Adverse events were more frequently observed in patients with pre-BI <60. Patients with pre-BI <60 had worse long-term outcomes. On multivariable analysis, hypoalbuminemia, end-stage renal disease, and BI at discharge <60 were significant predictors of 3-year outcomes, whereas pre-BI <60 was not a significant predictor of either outcome.


CONCLUSIONS
It is not BI at admission, but BI at discharge that determines long-term outcome.
