Developing an initial physical function item bank from existing sources.

The objective of this article is to illustrate incremental item banking using health-related quality of life data collected from two samples of patients receiving cancer treatment. The kinds of decisions one faces in establishing an item bank for computerized adaptive testing are also illustrated. Pre-calibration procedures include: identifying common items across databases; creating a new database with data from each pool; reverse-scoring "negative" items; identifying rating scales used in items; identifying pivot points in each rating scale; pivot anchoring items at comparable rating scale categories; and identifying items in each instrument that measure the construct of interest. A series of calibrations were conducted in which a small proportion of new items were added to the common core and misfitting items were identified and deleted until an initial item bank has been developed.

Course of functional improvement after stroke, spinal cord injury, and traumatic brain injury.

OBJECTIVE: To examine functional improvement patterns of persons with stroke, traumatic brain injury (TBI), and spinal cord injury (SCI). DESIGN: Statistical analysis of data from a multisite study evaluating rehabilitation outcomes. SETTING: Eight inpatient rehabilitation facilities. PARTICIPANTS: A total of 314 consecutive admissions of persons with stroke, SCI, and TBI who received acute medical rehabilitation between 1994 and 1998. INTERVENTION: Calibration of motor and cognitive items from the FIM instrument, grouping of cases by number of weeks of rehabilitation (length of stay [LOS] groups), and plotting of weekly averages across time. MAIN OUTCOME MEASURES: Weekly motor and cognitive functional status. RESULTS: With the exception of cognitive functioning for persons with SCI, LOS was related to initial functional status, with patients with greater disability having longer LOS (eg, initial motor status for persons with stroke was 48.3 for those with a 2-week stay, 36.8 for a 6-week stay, with the averages between decreasing monotonically). With the exception of cognitive gains for person with TBIs, the amount of functional gain during rehabilitation was essentially the same for all LOS groups (eg, the overall average total motor gain for persons with SCI is 22.3, with no patterns of increase or decrease across LOS groups); however, the rate of improvement in motor (but not cognitive) functioning differed across LOS groups, with patients with shorter stays having the greater rates of improvement (eg, the overall average weekly motor gain for persons with SCI was 3.6, with the averages by LOS group monotonically decreasing from 6.4 for those with 4-week stays to 2.7 for those with 9-week stays). CONCLUSIONS: When examined separately for persons grouped by LOS, functional status improved linearly during the rehabilitation stay, with differences in rate of improvement depending on initial functional status.

Measuring unmet needs and services among persons with traumatic brain injury.

OBJECTIVES: (1) To develop a comprehensive list of needs and services appropriate for persons with traumatic brain injury (TBI); (2) to determine whether these needs and services formed unidimensional hierarchies from least common to most common; (3) to describe the relationship between unmet needs and services received; and (4) to estimate the extent to which a variety of demographic, injury, and service characteristics predict unmet needs. DESIGN: Statewide mailed survey. SETTING: Illinois communities. PARTICIPANTS: A total of 895 persons who had had a TBI recruited from Brain Injury Association members and rehabilitation service recipients. The median time post-TBI was 7 years; the median age was 37 years. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: A 27-item instrument assessing service needs and utilization of services, and equal-interval measures of needs and services derived with Rasch analysis. RESULTS: The most prevalent unmet needs were improving memory or problem-solving skills (51.9%), increasing income (50.5%), and improving job skills (46.3%). The instrument defined unidimensional and reliable constructs of needs and services. Persons with greater unmet needs tended to receive fewer services; to report lower life satisfaction and worse medical health and psychologic well-being since injury; to be younger, single, black, dependent in 1 or more daily activities; and to have more recent injuries. CONCLUSIONS: The results show the common pattern of unmet needs and services and emphasize the importance of comprehensive, statewide assessment of services and needs in developing policies.

Stroke rehabilitation: indwelling urinary catheters, enteral feeding tubes, and tracheostomies are associated with resource use and functional outcomes.

BACKGROUND AND PURPOSE: The aim of this study was to investigate the associations between tracheostomies, enteral feeding tubes, and indwelling urinary catheters and functional outcome measures, incidence of medical complications, and resource use in an inpatient stroke rehabilitation program. METHODS: A cohort of 1553 patients consecutively admitted for inpatient stroke rehabilitation was studied. Demographic and stroke characteristics, impairment (National Institutes of Health Stroke Scale) and disability level (Functional Independence Measure [FIM]), preexisting medical conditions, and the presence of tracheostomies, enteral feeding tubes, and indwelling urinary catheters were recorded at admission. The occurrence of medical complications during rehabilitation, discharge disability level, length of rehabilitation stay, and rehabilitation hospital charges were recorded at discharge. RESULTS: Compared with patients with no medical tubes, patients with 3 medical tubes had significantly higher National Institutes of Health Stroke Scale scores, lower admission and discharge FIM scores, reduced FIM efficiency scores (average FIM score change per day), and twice the number of medical complications. Patients with 3 medical tubes stayed 28 days longer in acute hospitalization and 20 days longer in rehabilitation compared with patients with no medical tubes. The presence of even a single medical tube was associated with longer length of stay, more medical complications during rehabilitation, and greater disability level at discharge. CONCLUSIONS: The presence of > or =1 medical tubes is associated with more severe and disabling strokes, an increased number of medical complications, longer acute and rehabilitation hospitalizations, and greater resource use.

Impact of respiratory complications on length of stay and hospital costs in acute cervical spine injury.

CONTEXT: Respiratory complications are frequent in patients with acute cervical spinal injury (CSI); however, the importance of respiratory complications experienced during the initial hospitalization following injury is unknown. OBJECTIVE: To determine if respiratory complications experienced during the initial acute-care hospitalization in patients with acute traumatic cervical spinal injury (CSI) are more important determinants of the length of stay (LOS) and total hospital costs than level of injury. DESIGN: A retrospective analysis of an inception cohort for the 5-year period from 1993 to 1997. SETTING: The Midwest Regional Spinal Cord Injury Care System, a model system for CSI, at Northwestern Memorial Hospital, a tertiary referral academic medical center. PATIENTS: Four hundred thirteen patients admitted with acute CSI and discharged alive. Patients with concurrent thoracic injuries were excluded. MAIN OUTCOME MEASURES: Initial acute-care LOS and hospital costs. RESULTS: Both mean LOS and hospital costs increased monotonically with the number of respiratory complications experienced (p < 0.001, between none and one complication, and between one and two complications; p = 0.24 between two and three or more complications). A hierarchical regression analysis showed that four variables-use of mechanical ventilation, occurrence of pneumonia, need for surgery, and use of tracheostomy-explain nearly 60% of the variance in both LOS and hospital costs. Each of these variables, when considered independently, is a better predictor of hospital costs than level of injury. CONCLUSIONS: The number of respiratory complications experienced during the initial acute-care hospitalization for CSI is a more important determinant of LOS and hospital costs than level of injury.

Impact of pediatric rehabilitation services on children's functional outcomes.

OBJECTIVES: Relatively little is known about the treatment effectiveness and functional outcomes of pediatric rehabilitation therapies. This study was conducted to gain knowledge of the type and quantity of inpatient rehabilitation services provided to children who received acute inpatient rehabilitation and compare functional gains by age and diagnosis. METHOD: A retrospective cohort design was used. Records of rehabilitation therapies and functional assessments of 814 pediatric patients who received inpatient rehabilitation during 1996, 1997, and 1998 were collected. The admission and discharge item ratings of the WeeFIM instrument were first transformed into interval-level measures of self-care, mobility, and cognition. Parametric analyses were used to compare functional gains across impairment groups and to examine the relationship between amount of treatment and functional gains. RESULTS: Occupational therapy and physical therapy were the primary rehabilitation services received by patients across impairment groups (98% and 99%, respectively). A large proportion of children with traumatic brain injuries also received speech therapy (97%) and psychology services (60%). Across domains (self-care, mobility, cognition), the largest gains were made by children who were older than 7 years and had traumatic injuries. Functional gains were significantly related to the amount of discipline-specific treatment received, after controlling for age, impairment, and functional status at admission. CONCLUSION: Rehabilitation therapy provision in pediatric inpatient rehabilitation varies greatly depending on children's age and the nature of the impairment. Systematic reporting of type and quantity of rehabilitation therapies along with functional assessments before and after hospitalization would allow researchers to track functional changes and study the determinants of functional improvement.
