CROSS-VALIDATION OF A MODEL FOR PREDICTING FUNCTIONAL STATUS AND LENGTH OF STAY IN PATIENTS WITH STROKE
Objective: In a study published in 2002, it was observed that a variable composed by the Functional Independence Measure (FIMTM) and the trunk control test at admission predicted 66. 5% of the FIMTM at discharge in stroke patients. The objective was to confirm the reproducibility of this predictive model. Methods: Retrospective study of 245 hemiparetic stroke inpatients of the rehabilitation department. The main variables studied were: trunk control test FIMTM at admission and compound variable (FIMTM+trunk control test) as independent variables and FIMTM at discharge and inpatient rehabilitation length of stay as dependent variables. Results: Correlation between the compound variable and the length of stay was statistically significant (r =0. 59), as was its correlation with the total FIMTM at discharge (r =0. 82). The regression analysis predicted 34. 3% of the length of stay variability and 66. 4% of the total FIMTM at discharge variability. Conclusion: The compound variable is a reliable tool because of its reproducibility in predicting the functional level at hospital discharge in hemiparetic patients.
