Development and Validation of Prognostic Indices for Recovery of Physical Functioning Following Stroke: Part 2

This study aimed to develop a prognostic index for achievement of modified independence (Functional Independence Measure grade VI) after completion of either comprehensive or consultative rehabilitation after stroke. Data included 5316 patients with stroke discharged from VAMCs who received rehabilitation services while hospitalized and who were physically dependent at first assessment. The index was derived with use of 60% of the sample and validated in the remaining 40% of the sample. Points derived from the β coefficients of a multivariable logistic model added to scores that were associated with the likelihood of recovery. Seven independent predictors were identified through logistic regression in the derivation sample: initial physical grade (Ior II = 0 points; III = 2 points; IV = 4 points; V = 5 points), initial cognitive stage (I or II = 0 points; III = 2 points; IV = 3 points, V or VI = 4 points; VII =5 points), type of rehabilitation (consultative = 0 points; comprehensive = 4 points), age (<60 years = 3 points; 60-79 years = 2 points; ≥80 years = 0 points), time from initial to final physical grade assessment (1-2 days = 0 points; ≥3 days = 2 points), absence of urinary procedures (3 points), and absence of diabetes with complications (1 point). The following proportions of patients recovered to physical grade VI for the first, second, third, and fourth quartile scores, respectively: 0.59% (score ≤9), 3.87% (score = 9-11), 14.19% (score = 12-15), and 37.38% (score ≥16).

Functional recovery to physical grade VI can be predicted on the basis of patients' initial status following a stroke occurs and the type of rehabilitation services to be provided by using a simple scoring system.
