Physical Function ICU Test (PFIT)

Exploratory: Unruptured Cerebral Aneurysms and Subarachnoid Hemorrhage (SAH)
|Short Description of Instrument||
The Physical Function ICU Test (PFIT) is a measure of function for those who need mechanical ventilation for four or more days. It is used to evaluate changes in patient strength and outcomes in the intensive care unit (ICU).
The test can be performed when the patient is alert enough by testing the following criteria:
Look at me
Poke out your tongue
Nod your head
Raise your eyebrows
-Assistance – sit to stand: 0, 1, or 2 assistants needed
-Cadence – steps/min: Calculated from maximal duration of marching on the spot and number of steps.
-Upper and Lower Limb Strength – Greatest of left and right using the Oxford grading system recorded from 0 (no contraction) to 5 (movement against gravity with full resistance)
Psychometrics: good reliability, validity, responsiveness, (MCID=1.5), predictive of length of stay (acute hospital) and discharge muscle strength.
Points are out of a maximum score of 12.
