Measuring developmental and functional status in children with disabilities.
This study compared performance on the Functional Independence Measure for Children (WeeFIM), the Battelle Developmental Inventory Screening Test (BDIST), and the Vineland Adaptive Behavior Scales (VABS) in children with developmental disabilities. The three instruments were administered to 205 children with identified disabilities. All 205 children were tested using the WeeFIM instrument. The BDIST was administered to 101 children and the VABS to the remaining 104 children. Administration was counterbalanced and randomized across all three instruments. A proportional sampling plan was used to select the 205 children, who ranged in age from 11 to 87 months. A variety of medical diagnoses and levels of severity of motor, cognitive, and communication impairments were systematically included in the sample. Correlations (r) among subscales for all three instruments ranged from 0.42 to 0.92. Correlations for total scores ranged from 0.72 to 0.94. Analyses of potential moderator variables found no significant relation between age and severity of disability (r=0.05) or between socioeconomic status (SES) and severity of disability (r=0.21). Correlations with age were strongest for those subscale scores involving gross and fine motor skills. Correlations with SES and subscale scores ranged from 0.03 to 0.18. The three instruments provide important information regarding childhood performance in motor, self-care, communicative, cognitive, and social skills. The WeeFIM instrument requires less administration time and provides information directly relevant to evaluating functional outcomes for children with disabilities and their families.

A functional strategy for classifying patients after traumatic spinal cord injury.
OBJECTIVES: To present a function-based strategy for classifying patients by expected functional outcomes measured as patients' performances at discharge on each of the 18 component items of the FIMtrade mark instrument (previously known as the Functional Independence Measure). METHODS: Data included records from 3604 inpatients with traumatic spinal cord injury discharged from 358 rehabilitation units or hospitals in 1995. The function-based strategy assigned patients to four Discharge Motor-FIM-Function Related Groups defined by patients' admission performance on the motor-FIM items. RESULTS: The majority of patients whose motor-FIM scores at admission were above 30 were able to groom, dress the upper body, manage bladder function, use a wheelchair, and transfer from bed to chair, either independently or with supervision, by the time of discharge from inpatient rehabilitation. Most patients whose scores were above 52 attained independence in all but the most difficult FIM tasks, such as bathing, tub transfers, and stair climbing. CONCLUSIONS: This classification scheme can be used to determine the degree to which patients' actual FIM outcomes compare to other individuals who had similar levels of disabilities at the time of admission to rehabilitation. The clinician can apply these 'FIM item attainment benchmarks' retrospectively in quality improvement, in guideline development, and in anticipating the types of post-discharge care required by clinically similar groups.

A profile of multiple sclerosis: the New York State Multiple Sclerosis Consortium.
We have obtained a current profile of multiple sclerosis York State through a centralized patient registry and standardized data collection instrument associated with the New York State Multiple Sclerosis Consortium of 12 MS centers located throughout the state. Data from the first 3019 patients with clinically definite MS revealed a clear relationship between MS disease type, duration of disease, and severity of physical disability. Patients with relapsing disease had disease durations approximately half as long as those with progressive forms of the disease (means approximately 6 years versus 11 years). The majority of patients with relapsing disease had Expanded Disability Status Scale (EDSS) scores of 4.0 or less (self-sustained, fully ambulatory), whereas the majority of patients with progressive disease types had EDSS scores of 6.0 or greater (at least unilateral assist for walking). These findings emphasize the importance of early intervention in patients with relapsing disease to slow or prevent the accumulation of physical disability associated with progressive types of disease. Progressive disease was associated with lack of full-time employment and being disabled before the age of 60 years. Patients with relapsing disease were more likely to be employed and have private forms of insurance, whereas patients with progressive types of disease were more likely to have government-supported insurance to cover medical expenses.

Does the functional assessment measure (FAM) extend the functional independence measure (FIM) instrument? A rasch analysis of stroke inpatients.
Adding the items of the Functional Assessment Measure (FAM) to the Functional Independence Measure (FIM instrument) has been proposed as a method to extend the range of the FIM, particularly when assessing functional status in rehabilitation patients with brain injury, including stroke. It has been proposed that this approach is especially helpful in ameliorating ceiling effects when brain-injured patients have reached the end of their inpatient rehabilitation stay or are being seen in outpatient settings. In the present study, 376 consecutive stroke patients on a Canadian inpatient rehabilitation unit were concurrently administered the FIM and the FAM. Rasch analysis was used to evaluate how well the FAM items extended the difficulty range of the FIM for both the Motor and Cognitive domains. Within the Motor domain, only the FAM item assessing Community Access was found to be more difficult than extant FIM items, and this item showed some tendency to misfit with the other motor items. In the Cognitive domain, the only FAM item with a higher difficulty level than the FIM items was that assessing Employability. Notably, strict adherence to scoring guidelines for these two FAM items requires taking patients out into the community to evaluate their actual performances, a practice unlikely in the typical inpatient stroke rehabilitation unit. Results indicate that use of the entire FAM as an adjunct to the FIM reduces test efficiency while providing only minimal additional protection against ceiling effects.

Status of functional outcomes for stroke survivors.
In the past, it has taken several years to accumulate a sufficient number of subjects in the community-based studies to arrive at generalized conclusions. With an ongoing database, such as resides at CFAR-UDSMR, it is possible to collect a large number of cases within a relatively short period of time. Further, it is relatively easy to perform continuous monitoring in order to determine trends that may be occurring as a result of the changing scenes in health care delivery. It has been possible to uncover patterns of scoring the functional status of patients that reveal a consistent picture of an underlying biology of disability and predictable characteristics in patients' courses through the rehabilitation process. Newer analytic methods have allowed one to predict expected recovery patterns. This new information will allow one to better measure and manage outcomes, to improve the quality of care, to improve cost-effectiveness, and to better manage financial risk. These are the tools necessary for clinicians to incorporate into practice, as expectations with respect to outcomes and reimbursement for health care are changing. All of the marks associated with FIM and UDSMR belong to the Uniform Data System for Medical Rehabilitation, a division of UB Foundation Activities, Inc.

Magnetic resonance studies of intramuscular interferon beta-1a for relapsing multiple sclerosis. The Multiple Sclerosis Collaborative Research Group.
The Multiple Sclerosis Collaborative Research Group trial was a double-blind, randomized, multicenter, phase III, placebo-controlled study of interferon beta-1a (IFNbeta-1a; AVONEX) in relapsing forms of multiple sclerosis. Initial magnetic resonance imaging results have been published; this report provides additional results. Treatment with IFNbeta-1a, 30 microg once weekly by intramuscular injection, resulted in a significant decrease in the number of new, enlarging, and new plus enlarging T2 lesions over 2 years. The median increase in T2 lesion volume in placebo and IFNbeta-1a patients was 455 and 152 mm3, respectively, at 1 year and 1,410 and 628 mm3 at 2 years, although the treatment group differences did not reach statistical significance. For active patients, defined as those with gadolinium enhancement at baseline, the median change in T2 lesion volume in placebo and IFNbeta-1a patients was 1,578 and -12 mm3 and 2,980 and 1,285 mm3 at 1 and 2 years, respectively. Except for a minimal correlation of 0.30 between relapse rate and the number of gadolinium-enhanced lesions, correlations between MR and clinical measures at baseline and throughout the study were in general poor. Once weekly intramuscular IFNbeta-1a appears to impede the development of multiple sclerosis lesions at an early stage and has a favorable impact on the long-term sequelae of these inflammatory events as indicated by the slowed accumulation of T2 lesions.

Diagnostic coding and medical rehabilitation length of stay: their relationship.
OBJECTIVE: To determine if diagnostic information provided in the form of International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes improves rehabilitation length of stay (LOS) prediction when used in combination with the Functional Independence Measure-Function Related Groups (FIM-FRGs) classification system. DESIGN: Various models characterizing diagnostic information using ICD-9-CM codes were created that included individual ICD-9-CM codes and groupings of those codes by organ or etiology involved. Each method was evaluated using linear regression with the natural logarithm of LOS as the dependent variable. Separate validation data sets were held back to quantify the incremental effect of diagnosis when combined with the FIM-FRG classification system. SETTING: Records from 252 rehabilitation facilities and hospital units across the nation. PATIENTS: Analyses were undertaken using 82,646 records from patients discharged in 1992. RESULTS: The addition of ICD-9-CM diagnostic information to the FIM-FRG classification system increased the variance explained by a maximum of 1.9%, from 31.5% to 33.4%. CONCLUSIONS: Refinement of the FIM-FRGs to include ICD-9-CM diagnoses does not appear warranted on the basis of the small increase in the percentage of explained variance in LOS. We believe the lack of improved prediction with the addition of ICD-9-CM codes relates primarily to incomplete coding practices and to the effect of patients' diagnoses being absorbed in variables as already expressed by the FIM-FRG system. Although ICD-9-CM codes, overall, did not greatly improve LOS prediction, they appeared to have some impact in certain impairment categories.

Outcomes in the first 5 years after traumatic brain injury.
OBJECTIVE: To examine the extent to which outcomes from traumatic brain injury differ as a function of time and can be predicted at discharge from inpatient rehabilitation. DESIGN: Survey method employing cross-sectional analyses. SETTING: An inpatient brain injury rehabilitation unit in a large midwestern academic medical center. SUBJECTS: Ninety-five adults with traumatic brain injuries, 6 months to 5 years after inpatient rehabilitation, stratified by time postdischarge. MAIN OUTCOME MEASURES: Functional Independence Measure (FIM), Sickness Impact Profile (SIP), Medical Outcomes Survey SF-36, Community Integration Questionnaire (CIQ), Craig Handicap Assessment and Reporting Technique (CHART), Brief Symptom Inventory (BSI), Satisfaction With Life Scale (SWLS), and indices of current psychosocial functioning. RESULTS: Substance abuse, need for supervision, life satisfaction, and selected subscales of the CIQ and CHART differed over the period 6 months to 5 years after discharge. Approximately 75% of the variance in current FIM scores, and 40% to 50% of CHART, CIQ, and SIP total scores, could be predicted at time of discharge. CONCLUSIONS: Outcomes over the first 5 years after discharge were dynamic, with most change being improvement, at least after the first 2 years. Important aspects of outcome could not be predicted based on premorbid characteristics, injury severity, and initial functional abilities.

Functional task benchmarks for stroke rehabilitation.
OBJECTIVE: To determine typical outcome "benchmarks" for 18 functional tasks in patients undergoing stroke rehabilitation. The benchmarks are intended to serve as points of reference to which the outcomes of patients with similar impairments and degrees of disability can be compared. SUBJECTS: Records from 26,339 stroke patients discharged from 252 inpatient facilities across the United States that submitted 1992 data to the Uniform Data System for Medical Rehabilitation. METHODS: Stroke impairment was detailed as the presence or absence of hemiparesis resulting from stroke and the side(s) of involvement. Within each of five stroke impairment categories, patients were further classified by the Functional Independence Measure-Function-Related Groups (FIM-FRGs) into nine syndromes by degree of disability (admission motor and cognitive FIM scores) and by age. Outcomes were determined for each stroke syndrome at patients' discharge from medical rehabilitation. MAIN OUTCOME MEASURES: Patients' median performance levels on each of the 18 items making up the FIM, length of stay, and community discharge rates. RESULTS: The majority of patients whose admission motor FIM scores were above 37 were able to eat, groom, dress the upper body, and manage bladder and bowel functions independently by discharge. In addition to these tasks, most of those whose motor FIM scores were above 55 were able to dress the lower body, bathe, and transfer onto a chair/bed or toilet. The majority of patients whose initial motor FIM scores were above 62 points and whose cognitive FIM scores were above 30 gained independence in most tasks, including stair climbing and tub transfers. Community discharge rates ranged from 51.6% for the group of patients with the most severe disabilities to 99.2% for the group with the least severe disabilities. CONCLUSION: The clinician can apply these benchmarks to guideline development and quality improvement, and in establishing patient goals.

Rasch analysis of the Functional Independence Measure (FIM) Mastery Test.
OBJECTIVE: To evaluate the range, distribution, and unidimensionality of the items included in Version Five of the Functional Independence Measure (FIM) Mastery Test, a 54-item written examination used to determine FIM rating proficiency by professionals who administer the instrument. STUDY DESIGN: Rasch analysis of the test results of 6,645 clinicians who took the FIM Mastery Test in 1996. RESULTS: Overall, clinicians performed well on the test. When the mean item difficulty was centered at 50, and the test scores were calibrated to range from 0 to 100 logits, the mean person ability level was 77 logits. Fit statistics indicated that the test was unidimensional, measuring a common theme. While the item separation index value was 17, 22 items were not efficient in determining the clinicians' ability levels. Analysis of the logit values by the correct response showed that descriptions of Total Assistance (Level 1) and Complete Independence (Level 7) were easiest for clinicians to score correctly. CONCLUSION: The examination measures the common theme of FIM knowledge in a consistent manner. Further, the results suggest that the FIM Mastery Test may be shortened, perhaps by eliminating one of the three case studies, and improved by adding more challenging questions. In addition, FIM training should focus on distinguishing among levels 2 through 6, since clinicians had more difficulty identifying these levels.

Comparing consumer and clinician values for alternative functional states: application of a new feature trade-off consensus building tool.
OBJECTIVE: To present the Features-Resource Trade-Off Game (Features Game) as a new method for comparing preferences for alternative outcomes among different groups of people. DESIGN: The Features Game is illustrated by comparing preferences for recovery among the 18 functional status items making up the Functional Independence Measure. Methods involved trading levels of independence (resources) across the different items (features). SETTING: Ten community-dwelling consumers with physical disabilities and 10 rehabilitation clinicians participated in four separate expert panels-two in Houston and two in Philadelphia. MAIN OUTCOME MEASURES: Five sets of hierarchical stages defined by the four separate panels specifying the profiles of function believed to most foster independent living. RESULTS: Cognitive and communication skills were selected preferentially over the recovery of physical tasks by all panels, but, in comparison to clinicians, consumers were more willing to accept mild deficits in cognitive skills as trade for realizing earlier recovery of physical abilities. CONCLUSION: The overwhelming choice of cognitive and communication abilities over physical abilities suggests a need to enhance therapeutic efforts in those areas. More subtle differences in consumer and clinician preferences emphasize the importance of establishing consumer-oriented goals.

Comparing the ability of various compositive outcomes to discriminate treatment effects in MS clinical trials. The Multiple Sclerosis Collaborative Research Group (MSCRG).
We compared the ability of the Kurtzke Expanded Disability Status Scale (EDSS) and a composite outcome of non-physician-based measures of time to ambulate 25 feet (TA) and manual dexterity (the Box and Block Test [BBT], and 9-Hole Peg Test [9HPT]) to discriminate treatment effects in the Phase III study of interferon beta-1a. A log-rank comparison of Kaplan-Meier curves by treatment group showed the non-physician-based composite of BBT, 9HPT, and TA was of comparable sensitivity (P = 0.013) in discriminating sustained treatment failure as the EDSS alone (P = 0.029). The composite of BBT, 9HPT, TA, and EDSS was more sensitive (P = 0.009) in discriminating sustained treatment failure than the EDSS alone. Compositive outcomes of the EDSS and non-physician-based measures of manual dexterity and timed ambulation provide an appealing strategy to reduce the number of patients required to discriminate treatment effects in MS clinical trials.

Development of an academic productivity scale for departments of physical medicine and rehabilitation.
OBJECTIVE: To determine which factors related to departments of physical medicine and rehabilitation (PM&R) might contribute to the academic productivity of members of the teaching staff of those departments, and to develop an instrument that measures them. DESIGN: Prospective, inception cohort. SETTING: University medical center, academic PM&R departments. PARTICIPANTS: PM&R academic departments. INTERVENTION: Over a 6-year period, seven PM&R departments volunteered to use this instrument to measure academic productivity at 2-year intervals. Rasch analysis was applied to the generated data. MAIN OUTCOME MEASURE: Measurable items that were included in questions of the scale fell into six categories: research funding and/or experience; scholarly productivity; equipment and facilities; quality of the training program for resident physicians; continuing education efforts in research methodologies and professional organizational participation; and departmental leadership. Rasch analysis was applied to evaluate a new outcome instrument to measure academic productivity in PM&R departments. RESULTS: Twenty-eight of the original 42 questions survived the Rasch analysis and were retained. Questions were dropped either because they did not fit the Rasch analysis (4 of 42 questions) or because application of the Rasch analysis demonstrated that they were inappropriately or outstandingly easy (10 of 42 were inappropriately or outstandingly easy). CONCLUSION: This shortened instrument of 28 questions fits the Rasch analysis, has questions that evently range from easy to very difficult, and addresses six measurable categories that are correlates of PM&R departmental influences on the academic productivity of the PM&R teaching staff.

Discharge motor FIM-function related groups.
OBJECTIVE: To develop a patient classification system that groups patients achieving similar functional outcome scores by discharge from medical rehabilitation. DESIGN: Patient groups were developed using a recursive partitioning algorithm and clinical input. Results were validated in a separate set of patient records. SETTING: Two hundred fifty-two free-standing rehabilitation hospitals and distinct part units that participate in the Uniform Data System for Medical Rehabilitation. PATIENTS: The 84,492 rehabilitation inpatients discharged in 1992 were grouped into 20 impairment categories. MAIN OUTCOME MEASURE: Discharge score on the motor subscale of the Functional Independence Measure (FIM). RESULTS: In the Discharge Motor FIM-Function Related Groups (DMF-FRGs) system, patients are first classified into one of 20 impairment categories and then into FRGs by their admission motor FIM scores. Some FRGs are also subdivided on the basis of admission cognitive FIM scores and age. The entire system consists of 139 patient groups that explain 63% of the variation in motor FIM discharge scores in the validation data set. Nontraumatic brain injury and joint replacement DMF-FRGs are provided as examples. CONCLUSION: Clinicians can use the DMF-FRGs to identify groups of patients whose motor FIM scores at discharge are below, within, or above nationally established ranges of values for the purpose of outcomes management, guideline development, and quality improvement. The DMF-FRGs can also be considered in the design of an outcome-based payment system for medical rehabilitation.

Validity of the functional independence measure for persons with traumatic brain injury.
OBJECTIVE: Replicate and extend studies of the construct validity of the Functional Independence Measure (FIM) for persons with traumatic brain injury (TBI). DESIGN: A cross-sectional study of admissions to acute rehabilitation evaluated 6 months to 5 years after discharge. SETTING: An inpatient brain injury rehabilitation unit in a large, academic medical center. SUBJECTS: Ninety-five patients with primary diagnosis of TBI stratified by time postdischarge. MAIN OUTCOME MEASURES: Prediction of (1) average daily minutes of assistance and (2) supervision required in comparison to the Sickness Impact Profile (SIP) and SF-36. RESULTS: The FIM was highly predictive of minutes of assistance (83% accuracy), supervision (82% accuracy), and the need for either type of assistance (78% accuracy). Prediction was only minimally improved by measures of neurobehavioral impairment. The accuracy of the FIM was superior to the SIP and SF-36. CONCLUSIONS: Results provided substantial support for the validity of the FIM as a measure of functional independence for persons with TBI. The importance of supervision as a type of assistance required after TBI was evident, with the FIM highly predictive of this need, as well.

Interrater agreement and stability of the Functional Independence Measure for Children (WeeFIM): use in children with developmental disabilities.
OBJECTIVE: Examination of the interrater agreement and stability of ratings obtained using the Functional Independence Measure for Children (WeeFIM) in a sample of children with developmental disabilities. DESIGN: A relational design was used in which two sets of WeeFIM scores were collected under four conditions: same rater-short interval; same rater-long interval; different rater-short interval; and different rater-long interval. SETTING: WeeFIM scores were collected in outpatient developmental rehabilitation centers, school programs, and the children's homes. PARTICIPANTS: Data were collected for 205 children ranging in age from 11 to 87 months. All children had a medical diagnosis of disability and were receiving habilitative-educational intervention or follow-along services including neurodevelopmental surveillance. INSTRUMENT: The WeeFIM instrument examines basic daily living and functional skills in children from birth to 7 years of age. The WeeFIM is modeled after the Functional Independence Measure (FIM) for adults and includes 18 items in the following subscales: self-care, sphincter control, transfers, locomotion, communication, and social cognition. RESULTS: Kappa values for items ranged from .44 to .82. Intraclass correlation coefficients (ICC) for the six subscales ranged from .73 to .98. Total WeeFIM ICC values were greater than .95 for all analyses. CONCLUSIONS: The WeeFIM ratings for the 205 children with developmental disabilities participating in this investigation were consistent across raters and time.
