The physical function intensive care test: Implementation in survivors of critical illness

Abstract

Background. Recent studies have demonstrated safety, feasibility, and decreased hospital length of stay for patients with weakness acquired in the intensive care unit (ICU) who receive early physical rehabilitation. The scored Physical Function in Intensive Care Test (PFIT-s) was specifically designed for this population and demonstrated excellent psychometrics in an Australian ICU population.Objective.
