Impact of osteoarthritis on rehabilitation for persons with hip fracture.

OBJECTIVE: To determine the impact of osteoarthritis (OA) on length of rehabilitation stay, Functional Independence Measure (FIM Instrument) ratings at discharge and followup, functional gain, and percentage of patients discharged home. METHODS: We conducted a retrospective cohort analysis using a national registry of US medical rehabilitation inpatients. We obtained standardized data for all patients admitted after a hip fracture between 1994 and 2001. Our primary analytical method was multiple regression analysis. Outcome variables were length of stay, FIM Instrument ratings at discharge and followup, functional gain, and percentage of patients discharged home. The predictor variable was the presence of OA. Covariates were age, sex, race/ethnicity, other comorbidity, admission FIM ratings, total hip replacement, and time to followup. RESULTS: We studied 1,953 patients with OA and 11,441 patients without OA admitted to inpatient rehabilitation facilities after hip fracture. Mean +/- SD length of stay for patients with OA was 18.1 +/- 10.0 days versus 16.5 +/- 8.9 days for those without OA (P < 0.01). After adjusting for age, sex, race/ethnicity, comorbidity, admission FIM ratings, and total hip replacement, OA was associated with a longer rehabilitation stay (1.4 days; P < 0.01) and slightly higher discharge FIM ratings; however, OA was not associated with lower weekly rehabilitation gain, followup FIM ratings, and percentage discharged home. CONCLUSION: Persons with hip fracture and OA had longer inpatient rehabilitation length of stay than persons without OA, but there were similarities in weekly rehabilitation gain and percentage discharged home.

Poststroke rehabilitation: outcomes and reimbursement of inpatient rehabilitation facilities and subacute rehabilitation programs.

BACKGROUND AND PURPOSE: To assess whether poststroke rehabilitation outcomes and reimbursement for Medicare beneficiaries differ across inpatient rehabilitation facilities (IRFs) and skilled nursing facility (SNF) subacute rehabilitation programs. METHODS: Clinical data were linked with Medicare claims for 58,724 Medicare beneficiaries with a recent stroke who completed treatment in 1996 or 1997 in IRFs and subacute rehabilitation SNFs that subscribed to the Uniform Data System for Medical Rehabilitation. Outcome measures were discharge destination, discharge FIM ratings and Medicare Part A reimbursement during the institutional stay. RESULTS: IRF patients that were more likely to have a community-based discharge, compared with rehabilitation SNF patients, were patients with mild motor disabilities and FIM cognitive ratings of 23 or greater (adjusted odds ratio [AOR]=2.19; 95% CI: 1.52 to 3.14), patients with moderate motor disabilities (AOR=1.98; 95% CI: 1.49 to 2.61), patients with significant motor disabilities (AOR=1.26; 95% CI: 1.01 to 1.57) and patients younger than 82 with severe motor disabilities (AOR=1.43; 95% CI: 1.25 to 1.64). IRF patients with significant and severe motor disabilities achieved greater motor function of 2 or more FIM units compared with rehabilitation SNF patients. Medicare Part A payments for IRFs were higher than rehabilitation SNF payments across all subgroups. CONCLUSIONS: For most patients, poststroke rehabilitation in the more costly and intensive IRFs resulted in higher functional outcomes compared with care in a SNF-based rehabilitation program. IRF and SNF outcomes were similar for patients with minimal motor disabilities and patients with mild motor disabilities and significant cognitive disabilities. Cost-effectiveness analyses require considering the costs of the full episode of care.

Preliminary results for the PAR-PRO: a measure of home and community participation.

OBJECTIVE: To develop a measure of home and community participation related to the World Health Organization's International Classification of Functioning, Disability and Health. DESIGN: Cross-sectional analysis of survey data. SETTING: Nine medical inpatient rehabilitation facilities from 6 states. PARTICIPANTS: A total of 594 patients of mixed impairment type admitted for inpatient rehabilitation in 2002. Mean age was 74.0 years and 61.4% were women. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Reliability and validity of the participation instrument. RESULTS: A 20-item instrument of home and community participation was developed (PAR-PRO). The instrument showed good internal consistency and good Rasch person and item fit statistics. Four subfactors were identified beyond the unidimensional construct of participation including domestic management, socialization, physical vigor, and generative activities. The PAR-PRO total participation score correlated inversely with age (r=-.31, P<.001) but did not differ by sex. CONCLUSIONS: The 20-item PAR-PRO instrument of home and community participation displayed good psychometric characteristics. The instrument shows promise as a broad measure of home and community involvement for persons with disabilities. Further work is needed to support its application for people without disability.

Examination of follow-up therapy in patients with stroke.

OBJECTIVE: Examine the patterns and effect of follow-up therapy for persons with stroke. DESIGN: Retrospective analysis of national inpatient medical rehabilitation facilities and follow-up survey data from 1994 to 2001. A total of 45,164 patients received inpatient medical rehabilitation after a stroke. The mean age (+/- standard deviation) was 69.5 (+/-12.8) yrs, 48% were women, and 77% were non-Hispanic white. Average length of stay was 21.9 (+/-14.2) days. RESULTS: The highest gain in FIM instrument ratings for follow-up therapy was associated with a discharge FIM rating of > or =65. Patients with FIM ratings > or =65 at discharge who received follow-up therapy gained an average of 19.4 points between discharge and follow-up assessment compared with a mean gain of 15.1 points for persons who did not receive follow-up therapy. Validity was examined using 100 bootstrap replications. The percentage of persons with FIM instrument scores of > or =65 receiving follow-up therapy increased from 38% in 1994 to 58% in 2001. CONCLUSIONS: The differences in postdischarge FIM gains between patients with and without follow-up therapy were greatest among patients with discharge FIM instrument ratings of > or =65. Compared with patients whose discharge FIM ratings were >65, patients with discharge FIM scores of > or =65 who underwent follow-up therapy demonstrated substantially greater average postdischarge FIM gains than those with FIM ratings of >65.

Impact of osteoarthritis on the rehabilitation of patients following a stroke.

OBJECTIVE: To determine if functional gain for patients following stroke rehabilitation is adversely affected by osteoarthritis (OA). METHODS: A retrospective cohort analysis was conducted using data collected between 1994 and 2001 from a large national registry of US rehabilitation inpatients. Outcome variables were functional status (the Functional Independence Measure [FIM Instrument]) at discharge and followup, FIM gain during and after rehabilitation, length of stay, and discharge setting. The primary predictor variable was the presence of OA. Covariates were age, sex, race, other comorbidities, type of stroke, length of stay, and time to followup. Analysis was by multivariable regression. RESULTS: Data from 3,094 patients with OA and 44,943 patients without OA admitted following a stroke to inpatient rehabilitation facilities were analyzed. In unadjusted analyses, OA was associated with significantly higher FIM ratings than patients without OA at admission (mean +/- SD 65.7 +/- 19.2 versus 63.1 +/- 20.5; P < 0.001) and discharge (mean +/- SD 89.2 +/- 21.8 versus 87.7 +/- 23.0; P < 0.001), but with lower FIM ratings at followup (mean +/- SD 97.7 +/- 24.7 versus 99.7 +/- 24.9; P < 0.001). In multivariate analyses, adjusting for potential confounders, OA was associated with a 1.62-day increase in length of stay (95% confidence interval [95% CI] 1.15, 2.08) and a 1.37 smaller improvement in FIM scores between admission and followup (95% CI 0.62, 2.12). This smaller increase in FIM instrument score was caused by less improvement in FIM after discharge. CONCLUSION: OA impairs recovery from stroke. This is compensated for by longer length of stay for inpatient medical rehabilitation. Reimbursement systems may need to consider the impact of OA as a comorbid condition in patients receiving stroke rehabilitation.

Rehabilitation of children with traumatic brain injury: descriptive analysis of a nationwide sample using the WeeFIM.

OBJECTIVE: To describe functional capability at admission and discharge of children with traumatic brain injury (TBI) in rehabilitation settings. DESIGN: Descriptive analysis. SETTING: Inpatient pediatric rehabilitation hospitals in the United States. PARTICIPANTS: Children (N=3815) in 56 pediatric inpatient rehabilitation facilities who were discharged during 1999 to 2001. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Admission and discharge WeeFIM scores. RESULTS: Admission and discharge WeeFIM scores correlated positively with age at admission, time from injury to rehabilitation admission, and length of stay (LOS). Higher admission WeeFIM scores correlated with shorter LOS, shorter time from injury to admission to rehabilitation, and higher discharge WeeFIM scores. CONCLUSIONS: Children with TBI demonstrated significant improvement in functional measures during rehabilitation. Discharge function and LOS correlated with admission severity, with children who had higher functional status and shorter time between injury and rehabilitation care having higher discharge function and shorter LOS.

Outcomes and reimbursement of inpatient rehabilitation facilities and subacute rehabilitation programs for Medicare beneficiaries with hip fracture.

OBJECTIVE: We sought to assess whether outcomes and reimbursement differ for Medicare beneficiaries with hip fracture when treated in an inpatient rehabilitation facility (IRF) compared with a skilled nursing facility (SNF) subacute rehabilitation program. PARTICIPANTS: Clinical data were linked with Medicare claims for 29,793 Medicare fee-for-service beneficiaries with a recent hip fracture who completed treatment in 1996 or 1997 in rehabilitation facilities that subscribed to the Uniform Data System for Medical Rehabilitation. OUTCOME MEASURES: We measured discharge destination, change in motor FIM rating, and Medicare Part A reimbursement. RESULTS: For patients with moderate-to-severe and severe disabilities, case mix groups (CMGs) 704 and 705, the percentage of patients discharged to the community from IRFs was lower than for patients treated in subacute rehabilitation SNFs, after controlling for covariates. Adjusted odds ratios were 0.71 (95% confidence interval 0.55-0.92) for CMG 704 and 0.72 (95% confidence interval 0.63-0.83) for CMG 705. For patients in the 3 other CMGs, no significant differences were detected. Improvement in motor functional status was roughly equivalent for patients treated in IRFs and those treated in the subacute rehabilitation programs across all 5 CMGs, after controlling for covariates. Medicare Part A payments for IRFs were significantly higher than SNF payments across all CMGs. CONCLUSION: SNF-based subacute rehabilitation was less costly and outcomes were in most, but not all, instances similar or better than IRF-based rehabilitation for Medicare fee-for-service beneficiaries who had a recent hip fracture.

Psychometric properties and developmental differences in children's ADL item hierarchy: a study of the WeeFIM instrument.

OBJECTIVE: To investigate the measurement properties of the WeeFIM instrument and examine the developmental differences in motor item difficulty in a pediatric inpatient rehabilitation sample. DESIGN: Database approach, retrospective study, using 814 WeeFIM records from 12 facilities. Rasch rating scale analysis was used for all analyses. Data for the complete sample were used to evaluate the dimensionality and item fit of the WeeFIM instrument. Patients were then divided into three age groups, <3 yrs of age (toddlers), 3-7 yrs of age (preschoolers and kindergartners), and >7 yrs of age (school-age children), and their data were used to compare the order of motor items by level of difficulty within and across different age groups. RESULTS: Principal component analysis of the WeeFIM suggests distinct motor and cognitive scales. Within the motor scale, bowel and bladder items misfit, suggesting they measure a distinct aspect of function. The order of motor item difficulty, an indicator of construct validity, varies across age groups, suggesting that motor tasks present different challenges to children at different developmental stages: toileting is the most difficult, whereas locomotion is the easiest motor item for toddlers. For children >3 yrs of age, eating is easiest and stair climbing is most difficult, followed by tub transfer and bathing. CONCLUSIONS: Similar to the adult FIMtrade mark instrument, the WeeFIM instrument has two distinct dimensions. The motor items form a unidimensional construct with acceptable measurement properties. Developmental differences in motor task mastery among children with disabilities are assumed but rarely tested. As evidenced by the age-specific item hierarchies found in this study, developmental differences among children with disabilities mimic that of children without disabilities.

Trends in length of stay, living setting, functional outcome, and mortality following medical rehabilitation.

CONTEXT: Changes in reimbursement have reduced length of stay (LOS) for patients receiving inpatient medical rehabilitation. The impact of decreased LOS on functional status, living setting, and mortality is not known. OBJECTIVE: To examine changes in LOS, functional status, living setting, and mortality in patients completing inpatient rehabilitation. DESIGN: Retrospective cohort study from 1994 through 2001 using information submitted to the Uniform Data System for Medical Rehabilitation. SETTING AND PARTICIPANTS: Data were analyzed from 744 inpatient medical rehabilitation hospitals and centers located in 48 US states. A total of 148,807 patient records from 5 impairment groups (stroke, brain dysfunction, spinal cord dysfunction, other neurologic conditions, and orthopedic conditions) were examined. Patients' mean age was 67.8 (SD, 15.8) years; the sample was 59% female and 81% non-Hispanic white. MAIN OUTCOME MEASURES: Discharge setting, follow-up living setting, change in functional status, and mortality. RESULTS: Median LOS decreased from 20 to 12 days (P<.001) from 1994 to 2001. The proportional decrease in median LOS was greatest (42%) for patients with orthopedic conditions. Mean days to follow-up remained constant from 89 in 1994 to 90 in 2001. Functional status was clinically stable, while efficiency (functional status change divided by LOS) increased significantly (P<.001). Rates of discharge to home and living at home at follow-up remained stable, ranging from 81% to 93%. However, mortality at 80- to 180-day follow-up increased from less than 1% in 1994 to 4.7% in 2001. CONCLUSIONS: Length of stay for inpatient rehabilitation decreased substantially from 1994 to 2001. Effectiveness as measured by change in functional status did not change clinically, and living setting did not change. Efficiency for functional outcomes improved but mortality at follow-up increased.

Satisfaction with medical rehabilitation after spinal cord injury.

STUDY DESIGN: Retrospective. OBJECTIVE: To predict satisfaction with medical rehabilitation. SUMMARY OF BACKGROUND DATA: While spinal cord injury (SCI) patient satisfaction with life and community services has been investigated, satisfaction with medical rehabilitation has not. METHODS: Information submitted to the Uniform Data System for Medical Rehabilitation (1998-2001) by 134 hospitals/rehabilitation facilities in the United States (n = 6,205 patients with SCI) was examined. Predictors were sociodemographic variables, Case Mix Groupings (CMG) (401-505, 5001), length of stay, rehospitalization, follow-up therapy, and health maintenance. Satisfaction was assessed at a mean of 92.2 days (SD 11.9 days) postdischarge. Data were analyzed according to who reported the outcome (patient, n = 3,858 or family/other, n = 1,869). Statistical modeling was conducted using logistic regression. RESULTS: High overall satisfaction was reported (94%). Significant predictors for the patient report data were CMG and rehospitalization. Compared with CMG 5001 (short stay, <3 days), patients in CMGs 401/2/3 and 501/2/3/4/5 had a 54% to 74% lower likelihood of being dissatisfied. Rehospitalized patients had a higher likelihood of dissatisfaction (odds ratio 2.3, 95% confidence interval 1.7 to 3.2). Significant predictors for the family/other report data were CMG (compared to CMG 5001, CMGs 401/2, 403, and 501/2 had a 70% lower likelihood of dissatisfaction), rehospitalization (odds ratio 1.7, 95% confidence interval 1.1-2.5), and marital status (married = 50% lower likelihood of dissatisfaction, 95% confidence interval 0.26-0.96). CONCLUSIONS: Satisfaction with medical rehabilitation services following SCI is related to functional abilities, rehospitalization, and marital status. Slightly different results were found for whether satisfaction was rated by the patient or family/other. The complex relationships among satisfaction, patient demographics, and functional status require continued examination.

Comparison of logistic regression and neural network analysis applied to predicting living setting after hip fracture.

PURPOSE: Describe and compare the characteristics of artificial neural networks and logistic regression to develop prediction models in epidemiological research. METHODS: The sample included 3708 persons with hip fracture from 46 different states included in the Uniform Data System for Medical Rehabilitation. Mean age was 75.5 years (sd=14.2), 73.7% of patients were female, and 82% were non-Hispanic white. Average length of stay was 17.0 days (sd=10.6). The primary outcome measure was living setting (at home vs. not at home) at 80 to 180 days after discharge. RESULTS: Statistically significant variables (p <.05) in the logistic model included follow-up therapy, sphincter control, self-care ability, marital status, age, and length of stay. Areas under the receiver operating characteristic curves were 0.67 for logistic regression and 0.73 for neural network analysis. Calibration curves indicated a slightly better fit for the neural network model. CONCLUSIONS: Follow-up therapy and independent bowel and/or bladder function were strong predictors of living at home up to 6 months after hospitalization for hip fracture. No practical differences were found between the predictive ability of logistic regression and neural network analysis in this sample.

Risks of acute hospital transfer and mortality during stroke rehabilitation.

OBJECTIVE: To identify demographic, medical, and functional factors associated with transfer of stroke patients to acute hospital services and/or mortality during stroke rehabilitation. DESIGN: Two case-control studies in which logistic regression was used to control for clinical traits associated with differences in likelihood. SETTING: A total of 542 US inpatient and rehabilitation units. PARTICIPANTS: A total of 64,471 patients discharged during 1995. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Transfer to an acute hospital service and death. RESULTS: There were 5847 (9.1%) acute hospital transfers and 320 (0.5%) deaths. Greater disability at admission was associated with higher odds of both acute hospitalization and mortality. Cardiopulmonary arrest, chest pain, gastrointestinal problems, bleeding disorders, hypercoagulable states, and acute renal difficulties increased the relative odds of acute hospitalization from 3.1 (95% confidence interval [CI], 2.3-4.2) to 12.7 (95% CI, 9.2-17.6). The likelihood of mortality for patients 85 years of age or older was more than 2-fold (2.5; 95% CI, 1.7-3.6) that of patients 65 years of age or younger for blacks, it was nearly 2-fold (1.7; 95% CI, 1.3-2.3) compared with whites, after adjusting for clinical differences. CONCLUSION: Higher likelihoods of mortality among older patients versus younger, black patients versus white, and patients with more rather than less disability at admission suggest the need for greater vigilance in monitoring medical status.

Satisfaction with medical rehabilitation in patients with orthopedic impairment.

OBJECTIVE: To examine patient satisfaction after orthopedic impairment at 80 to 180 days after inpatient rehabilitation. DESIGN: Retrospective design examining records from facilities subscribing to the Uniform Data System for Medical Rehabilitation (UDSmr). SETTING: Information submitted to UDSmr from 1997 to 1998 by 177 hospital and rehabilitation facilities from 40 states. PARTICIPANTS: The sample (N=7781) was 72.63% female and 88.60% non-Hispanic white, with a mean age +/- standard deviation of 73.07+/-11.81 years, and average length of stay (LOS) of 13.84+/-10.48 days. INTERVENTION: Usual rehabilitation care. Main outcome measures Level of satisfaction 80 to 180 days after discharge as well as motor, cognitive, and subscale ratings for the FIM trade mark instrument. Predictor variables included gender, age, English language, marital status, discharge setting, LOS, rehospitalization, FIM gain, and primary payer. RESULTS: A logistic regression model was used to predict patient satisfaction at follow-up. Five statistically significant (P<.05) variables were found and correctly classified 94.9% of the patients. Discharge motor FIM rating, rehospitalization, age, patient's primary language, and discharge setting were associated with increased satisfaction. Discharge motor FIM ratings were significantly associated with increased satisfaction in patients with joint replacements and lower-extremity fractures. CONCLUSION: unctional and demographic variables were identified as predictors of satisfaction in patients with orthopedic impairments.

Staging functional independence validity and applications.

OBJECTIVES: To establish construct and predictive validity of the activities of daily living, sphincter-management, mobility, and executive-function (ASME) staging system of functional independence and to describe potential applications. DESIGN: National data were used to validate the stages. Sensitivity to functional change was addressed by comparing patients' stages at discharge to their stages at admission. Construct validity was assessed by examining stage distribution differences among groups of patients classified by impairment category. Predictive validity was determined by the degree to which high stages at admission predict discharge to the community and low stages at admission predict serious morbidity or mortality. SETTING: Inpatient rehabilitation facilities. PARTICIPANTS: Data from 231,686 individuals discharged from 560 US inpatient rehabilitation facilities in 1995. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Stage at rehabilitation discharge, community discharge, acute hospital discharge, or death while in rehabilitation. RESULTS: More than 90% of patients were discharged at a higher stage in at least 1 domain while not declining in any other domain. The odds (95% confidence interval) of community discharge for patients admitted at the highest compared with the lowest stage varied from 2.1 (1.9-2.2) to 3.1 (2.9-3.2), depending on the domain. The odds of acute hospitalization or death were reduced at the highest stages, compared with the lowest, by a factor ranging from .33 (.22-.49) to .65 (.61-.69). CONCLUSIONS: The ASME stages appear valid and sensitive to change. Functional Independence Staging (FIS) has relevance in establishing prognoses and in selecting among therapeutic modalities. FIS will facilitate the identification of meaningful functional goals and interpretable clinical trial endpoints. One of its most important applications could be in the establishment of outcome indicators for quality monitoring under the prospective payment system.

Functional independence staging: conceptual foundation, face validity, and empirical derivation.

OBJECTIVE: To develop a staging system for functional independence across the activities of daily living (ADLs), sphincter-management, mobility, and executive-function domains (ASME) for the FIM instrument that is consistent with the International Classification of Functioning, Disability and Health. DESIGN: National data were used to define the stages. We searched for the most likely configurations of item scores that increased ability to perform component activities in each domain by approximately 1 level per item per stage. SETTING: Inpatient rehabilitation facilities. PARTICIPANTS: Data from 218,290 people discharged from 560 US inpatient rehabilitation facilities in 1995. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Activity profiles formed from FIM scores. RESULTS: Seven stages were defined separately for each ASME domain. Stages approximate the average amount of effort expended by the patient when performing the component activities included in a domain, beginning with less than 25% of effort at the lowest total assistance (stage 1) and ending with 100% effort at the highest complete independence (stage 7). Consistent with developmental principles, independence is achieved at lower stages in the most fundamental activities of eating, transfers, and communication. Recovery of independence in the more difficult activities of bathing, stair climbing, and problem solving does not occur until the higher stages are reached. The degree of independence is described with a shorthand abbreviation of the domains followed by the stage the patient has reached in each domain. For example, ASME 5,1,6,7 indicates need for supervision in the ADLs (A-5), total assistance in sphincter management (S-1), modified independence in mobility (M-6), and complete independence in executive functions (E-7). CONCLUSIONS: ASME stages serve as a common language and shorthand for expressing the functional consequences of illness and injury, while complementing information about impairment and diagnosis, thereby facilitating communication, assessment, and goal setting in terms that are meaningful to patients and their care givers.

Predicting the achievement of 6 grades of physical independence from data routinely collected at admission to rehabilitation.

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. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: 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.
