Higher WIfI stage linked to longer stay, higher cost, worse survival

A retrospective single-center analysis of 1,252 patients undergoing lower extremity peripheral vascular interventions in Singapore examined associations between WIfI stage and hospital length of stay, inpatient costs, major amputation, and survival. The study reported that higher WIfI stages correlated with longer length of stay and higher inpatient costs, with each stage increment associated with an additional $7,637 in adjusted costs; Stage 4 patients had significantly increased risk of major amputation (SHR 2.50) and reduced overall survival (HR 1.38) compared with lower stages. The authors state this supports the value of WIfI classification for clinical and economic decision making in this Asian healthcare setting.

Most relevant for: Patients with chronic limb threatening ischaemia undergoing peripheral vascular intervention, particularly in Asian healthcare settings.
