OBJECTIVE : To develop prognostic indexes with which to establish the likelihood of individuals achieving specific grades of physical independence by the conclusion of inpatient rehabilitation. DESIGN: Logistic regression with prospective validation. SETTING: Five hundred sixty inpatient rehabilitation facilities. PARTICIPANTS: Records of 218,290 adults discharged in 1995 were used to establish the grades and the indexes predicting those grades. There were 259,806 1997 discharges included in the validation. Six physical independence grades reflecting the most likely profiles of performance across the 13 motor FIM items. RESULTS: After severity adjustment, patients 65 years of age or younger, compared with those 84 years of age or older, had odds ratios of reaching higher grades ranging from 1.5 (95% confidence interval [CI], 1.4-1.7) to 7.5 (95% CI, 4.3-13.1). Admission to rehabilitation within 2 weeks of disability was associated with more favorable prognoses. Areas under the receiver operating characteristic curve ranged from.80 to.94 for the indexes, with minimal shrinkage on prospective validation. CONCLUSION: The models have sufficient reliability to establish from admission information the likelihood that a patient will achieve a specific grade of physical independence by the time of discharge from rehabilitation. The capacity to quantify prognosis has clinical, policy, and research applications.
