The Stability and Workload Index for Transfer (SWIFT) score is a numerical index for predicting unplanned intensive care unit (ICU) readmission. Patient readmitted to the ICU after ICU discharge experience a higher mortality rate than predicted and a longer stay. The SWIFT score allows less subjective criteria on who is ready to leave the unit.
To determine if a patient should be transferred from the ICU to the general hospital environment.
Use in medical or surgical ICUs. SWIFT score variables and assigned points: the original source of initial ICU admission (ER department = 0 points, transferred from a ward or outside the hospital = 8 points); ICU length of stay in days (<2 = 0 points, 2-10 = 1 point, >10 = 14 points); last measured Pa02/FlO2 ratio during initial ICU admission (>400 = 0 points, (<400 and >= 150) = 5 points, (<150 and >= 100) = 10 points, <100 = 13 points); Glasgow Coma Scale at time of ICU discharge (>14 = 0 points, 11-14 = 6 points, 8-10 = 14 points, <8 = 24 points); Last arterial blood gas PaCO2 value (<45 mmHg = 0 points, >45 mmHg = 5 points). SWIFT scores greater than 15 (cut score) are considered negative, so the risk of unplanned ICU readmission is high on those cases.
Do not use in other critical care units than medical and/or surgical intensive care units.
