The art of medicine: subjective measures as predictors of outcome in stroke and traumatic brain injury.
This study was designed to explore new ways of predicting the functional outcomes of stroke and brain injury patients. Upon admission and initial assessment of functional performance, we used an on-line computer program to indicate the most important and subjective judgment items to set rehabilitation goals for patients. The functional performance and discharge outcomes of patients from an inpatient program were measured by using five nonmedical functional items from the patient evaluation conference system (PECS). For stroke patients we most frequently selected motor loss, perceptual/cognitive deficit, spasticity, sensory deficit (PECS medical items), and comprehension (subjective cue). For traumatic brain injury patients, however, we selected motor loss, perceptual/cognitive deficit, spasticity (PECS medical items), communication, and comprehension (subjective cues). Data were statistically analyzed using the Fisher Exact Test. Of the medical function items, a level of independence in the sensory deficit function in stroke patients at admission was associated with a patient achieving independence in ambulation at discharge. Demonstrating a moderate or maximum level of attention, concentration, and realism was positively related to a patient achieving a level of independence in ambulation at discharge. Independence in the function items of behavior and interaction was associated with moderate or maximum levels of comprehension at admission. In traumatic brain injury patients, none of the subjective cues were associated with achieving independence at discharge in any of the functional levels. This paper demonstrates the value of developing a way to assess subjective measures that are based on their ability to predict outcomes. Using such a method, new predictive measures can be developed.
