Unilateral spatial neglect: relation to rehabilitation outcomes in patients with right hemisphere stroke

OBJECTIVE: To examine the relation between left unilateral spatial neglect (USN) and rehabilitation outcomes in patients with right hemisphere stroke. DESIGN: A retrospective analysis of a database of right hemisphere stroke patients. SETTING: Acute inpatient rehabilitation hospital. PARTICIPANTS: Patients (N=175) with a diagnosis of right hemisphere stroke who had undergone a neuropsychologic screening including assessment of USN and depressive symptoms at time of admission to an inpatient rehabilitation program. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Functional status was evaluated with the FIM instrument at admission and discharge. The relationship between USN, depressive symptoms, cognitive functioning, length of stay (LOS), and rate of progress in rehabilitation was examined via univariate (correlational) and multivariate (Cox regression) analyses. RESULTS: Patients with USN had longer LOS and progressed more slowly compared with those without USN. When matched against patients with equally poor functional status at admission, USN patients still had longer admissions and progressed more slowly. CONCLUSIONS: USN is a unique predictor of rehabilitation outcomes in patients with right hemisphere stroke. Identification of those specific functional skill areas most affected by USN may make possible the development of targeted interventions aimed at these key areas.     

Association of antidepressant medication therapy with inpatient rehabilitation outcomes for stroke, traumatic brain injury, or traumatic spinal cord injury

Weeks DL, Greer CL, Bray BS, Schwartz CR, White JR Jr. Association of antidepressant medication therapy with inpatient rehabilitation outcomes for stroke, traumatic brain injury, or traumatic spinal cord injury.

Objective

To study whether outcomes in patients who have undergone inpatient rehabilitation for stroke, traumatic brain injury (TBI), or traumatic spinal cord injury (TSCI) differ based on antidepressant medication (ADM) use.

Design

Retrospective cohort study of 867 electronic medical records of patients receiving inpatient rehabilitation for stroke, TBI, or TSCI. Four cohorts were formed within each rehabilitation condition: patients with no history of ADM use and no indication of history of depression; patients with no history of ADM use but with a secondary diagnostic code for a depressive illness; patients with a history of ADM use prior to and during inpatient rehabilitation; and patients who began ADM therapy in inpatient rehabilitation.

Setting

Freestanding inpatient rehabilitation facility (IRF).

Participants

Patients diagnosed with stroke (n=625), TBI (n=175), and TSCI (n=67).

Interventions

Not applicable.

Main Outcome Measures

FIM, rehabilitation length of stay (LOS), deviation between actual LOS and expected LOS, and functional gain per day.

Results

In each impairment condition, patients initiating ADM therapy in inpatient rehabilitation had longer LOS than patients in the same impairment condition on ADM at IRF admission, and had significantly longer LOS than patients with no history of ADM use and no diagnosis of depression (P<.05). LOS for patients initiating ADM therapy as inpatients even exceeded LOS for patients without ADM history, but who had a diagnosis for a depressive disorder. Deviation in LOS was significantly larger in the stroke and TBI groups initiating ADM in IRF than their counterparts with no history of ADM use, illustrating that the group initiating ADM therapy in rehabilitation significantly exceeded expected LOS. Increased LOS did not translate into functional gains, and in fact, functional gain per day was lower in the group initiating ADM therapy in IRF.

Conclusions

Explanations for unexpectedly long LOS in patients initiating ADM in inpatient rehabilitation focus on the potential for ADM to inhibit therapy-driven remodeling of the nervous system when initiated close in time to nervous system injury, or the possibility that untreated sequelae (eg, depressive symptoms or fatigue) were limiting progress in therapy, which triggered ADM treatment.     

Prevalence of post-stroke depression in an Irish sample and its relationship with disability and outcome following inpatient rehabilitation

PURPOSE: (1). To examine the prevalence of depressive symptoms and operationally defined depressive disorder (major depression) in an Irish sample of subjects undergoing inpatient rehabilitation following their first stroke. (2). To investigate factors predictive of depression following stroke. (3). To examine the relationship between post-stroke depression and outcome following inpatient rehabilitation. METHODS: Fifty consecutive patients meeting inclusion criteria who were admitted for inpatient rehabilitation to a specialised unit following their first stroke were prospectively studied. Inclusion criteria: first stroke 3 - 12 months previously, lesion identified on CT or MRI, age 18 - 65 years, at least some sensory/motor impairment, no pre-existing disabling condition and Barthel Index score > 14 prior to stroke. Mood (Center for Epidemiologic Studies Depression scale, Hamilton Depression Rating Scale, DSM-IV diagnostic criteria for Major Depressive Disorder), Cognition (Mini-Mental State Examination) and Disability (Barthel Index, Rankin Disability Scale) were assessed one week after admission (baseline) and again after 2 months of rehabilitation. Outcome was measured as effectiveness of rehabilitation (Shah et al., 1990) and length of inpatient stay (LOS). RESULTS: 10/50 (20%) of the sample met criteria for major depressive disorder on admission. The best predictor of depression was gender, with females having a two-fold higher rate of both subjectively reported and objectively rated depressive symptoms. Depression was unrelated to baseline Barthel Disability, side of lesion or previous psychiatric history. The best predictor of effectiveness of rehabilitation was baseline Barthel Disability score. Depression did not predict either effectiveness or LOS. CONCLUSION: (1). Major depression is common in subjects undergoing rehabilitation following their first stroke. (2). Females appear to be especially at risk, possibly reflecting an increased general risk of depression. (3). Depression in our sample was not related to functional disability following stroke or early functional outcome following rehabilitation.

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.     

The impact of the inpatient rehabilitation facility prospective payment system on stroke program outcomes

OBJECTIVE: To examine the impact of the Medicare inpatient rehabilitation facility (IRF) prospective payment system (PPS) on outcomes in a stroke rehabilitation program. DESIGN: An analysis was performed on a database including 945 stroke patients admitted to an inpatient stroke rehabilitation program 5 yrs before implementation of the IRF PPS and 3.5 yrs after implementation. Patients were classified with regard to stroke location (left vs. right), level of cognitive impairment, presence/absence of unilateral neglect, and level of depressive symptomatology. Functional status was evaluated at time of admission and discharge by functional independence measure (FIM). Other outcome measures included length of stay (LOS) and discharge destination. The impact of IRF PPS on LOS, progress in rehabilitation, and discharge destination was examined via univariate analyses of covariance and logistic regression. RESULTS: Patients admitted after implementation of the IRF PPS had shorter LOS but made less progress, had lower functional levels at discharge, and had higher rates of institutional discharge. CONCLUSIONS: Although associated with decreased LOS, implementation of the IRF PPS was associated with decreased functional gains, lower discharge FIM levels, and higher rates of institutional discharge. Cost savings associated with the PPS must be considered in light of these untoward outcomes.     

Inpatient rehabilitation of patients requiring hemodialysis

OBJECTIVE: To evaluate the outcomes of patients who require hemodialysis and are admitted to an inpatient rehabilitation unit. DESIGN: Retrospective review of the data of all admissions to an inpatient rehabilitation unit in 2001. SETTING: University medical center. PARTICIPANTS: All inpatient rehabilitation admissions in 2001 (N=531), including 497 patients who did not require hemodialysis and 34 who required hemodialysis. INTERVENTION: A comprehensive rehabilitation program including physical therapy and occupational therapy. Speech and language therapy and rehabilitation psychology were provided when necessary. MAIN OUTCOME MEASURES: Length of stay (LOS), change in total score on the FIM instrument, FIM efficiency, and place of discharge. RESULTS: Admission and discharge FIM scores of the patients requiring hemodialysis were virtually identical to those of the other patients admitted to the unit. The average LOS of the hemodialysis patients was 5.4 days longer than that of the other patients, and, therefore, efficiency scores of the dialysis group were less than those of the other patients. The rate of discharge to the community did not differ significantly for the dialysis group. CONCLUSIONS: Patients who require hemodialysis can benefit from rehabilitation services. Their improvement on the FIM instrument is comparable to that of other patients, but their LOS may be longer than that of other patients.     

Impact of an inpatient rehabilitation facility on functional outcome and length of stay of burn survivors

This study reviewed the use of an inpatient rehabilitation unit for burn survivors. We hypothesized that adult burn patients admitted earlier to inpatient rehabilitation have an equal or better functional outcome than those remaining in acute burn center for rehabilitation care. Functional Independence Measure (FIM) data were prospectively collected on our burn center admissions dating January 2002 to August 2003. National rehabilitation data were acquired from eRehabData and burn literature. A total of 217 adult patients survived until hospital discharge, with 21 (9.7%) discharged to inpatient rehabilitation (REHAB). REHAB had larger burn injuries, more inhalation injuries, higher incidence hand/foot burns, and longer length of stay (LOS). REHAB had lower FIM upon rehabilitation facility admission than national averages but greater FIM improvement during comparable rehabilitation LOS. Although our earlier rehabilitation admission strategy results in more frequent rehabilitation unit referrals, patients had shorter burn center LOS and greater FIM improvement compared with limited national burn patient functional outcome data currently available.     

The relationship between therapy intensity and rehabilitative outcomes after traumatic brain injury: a multicenter analysis

OBJECTIVES: To identify factors relating to the intensity of rehabilitation services received and to ascertain the relation between injury outcomes, demographics, types of therapy, and the intensity of rehabilitation services provided. DESIGN: A multicenter, prospective, nonrandomized study with inpatient rehabilitation data collected between 1989 and 1996. SETTING: Three medical centers in the federally sponsored Traumatic Brain Injury Model Systems. In each setting, the continuum of care includes emergency medical services, intensive and acute medical care, and inpatient rehabilitation. PARTICIPANTS: A total of 491 consecutively enrolled patients with a mean age +/- standard deviation of 34.3+/-15.88 years recruited from 3 medical centers. To be included in the study, patients must have been at least 16 years of age, have presented to the emergency department within 24 hours of injury, and have received acute care and inpatient rehabilitation. INTERVENTIONS: Patients received comprehensive medical care along with a combination of rehabilitative therapies, including physical, occupational, psychologic, and speech therapy. MAIN OUTCOME MEASURES: Therapy intensity; levels of functional independence, cognitive function, functional gain, and treatment efficiency, as indicated by the FIM instrument; rehabilitation length of stay (LOS); and charges. RESULTS: Age predicted the intensity of both psychologic (P<.001) and total therapy (P<.01) services. Acute care LOS was also a significant predictor of psychologic services (P<.01). Only admission motor FIM was relevant in predicting speech services intensity (P<.01). Therapy intensity was predictive of motor functioning at discharge (P<.001). However, therapy intensity did not predict cognitive gain (P<.05). CONCLUSIONS: This study is among the first multicenter efforts to examine the potential benefits of individual therapy services. Findings support assertions that increased therapy intensity, particularly physical and psychologic therapies, enhances functional outcomes.     

Do preinjury alcohol problems predict poorer rehabilitation progress in persons with spinal cord injury?

OBJECTIVE: To determine whether a history of alcohol-related problems is associated with inpatient rehabilitation progress. DESIGN: Cross-sectional cohort survey. SETTING: Acute inpatient rehabilitation program in a level I trauma center. PARTICIPANTS: Seventy-six of 104 consecutive patients with spinal cord injury (SCI) who met inclusion criteria and had completed interviews and functional outcome data. Participants were on average 38 years old; 84% were white, and 86% were men. Forty-two percent had tetraplegia and 39% had a history of problem drinking. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: FIM instrument admission, discharge, and efficiency scores as well as rehabilitation length of stay (LOS). RESULTS: The group with a history of problem drinking had significantly lower FIM admission, discharge, and efficiency scores and longer rehabilitation LOS. After controlling for potential confounding factors, a history of problem drinking accounted for a significant proportion of the variance in FIM efficiency scores. CONCLUSIONS: A history of problem drinking may be a risk factor for poorer rehabilitation progress among patients with SCI. They may be more costly to rehabilitate and may be discharged before attaining an adequate level of independence. Despite this, the current rehabilitation prospective payment system does not recognize this common comorbid condition.     

The rapid resolution of depression and anxiety symptoms after lower limb amputation

OBJECTIVE: To ascertain the course of depressive and anxiety symptoms shortly after amputation and again after a period of inpatient rehabilitation. DESIGN AND SETTINGS: A cohort study in inpatients admitted to a rehabilitation ward after lower limb amputation. SUBJECTS: One hundred and five successive admissions over a one-year period. INTERVENTIONS: Nil. MAIN MEASURES: Hospital Anxiety and Depression Scale (HADS) on admission and discharge with correlation to demographic and patient features. RESULTS: At admission, 28 (26.7%) and 26 (24.8%) patients had symptoms of depression and anxiety respectively. This dropped to 4 (3.8%) and 5 (4.8%) by time of discharge, a mean of 54.3 days later. These reductions were statistically significant, as was the association between patients having symptoms of both depression and anxiety (P < 0.001). Patient stay was longer in those with symptoms (depression, P < 0.03; anxiety P < 0.001). There was no association with level of amputation, success of limb-fitting, age or gender. Depressive symptoms were associated with presence of other medical conditions (P < 0.01) and anxiety scores with living in isolation (P < 0.05). CONCLUSION: Depression and anxiety are commonly reported after lower limb amputation and previously thought to remain high for up to 10 years. We have found that levels of both depression and anxiety resolve rapidly. It is possible that a period of rehabilitation teaching new skills and improving patient independence and mobility may modify the previous bleak outlook of amputees. This positive finding may be useful in the rehabilitation of even the most distressed of amputees.     

Venous thromboembolism in a rehabilitation setting after major lower-extremity amputation

OBJECTIVE: To determine the prevalence of venous thromboembolic disease (VTED) and impact on functional outcome in patients with major lower-extremity (LE) amputation admitted to an inpatient rehabilitation unit. DESIGN: Retrospective medical records review. SETTING: Acute inpatient rehabilitation unit in a tertiary, urban academic medical center. PARTICIPANTS: Fifty consecutive patients admitted to an acute inpatient rehabilitation unit after a major LE amputation. Participants were screened at rehabilitation admission for LE deep vein thrombosis using duplex ultrasonography. INTERVENTIONS: Not applicable.Main outcome measures VTED incidence, FIM instrument, total rehabilitation charges, and length of stay (LOS). RESULTS: Six of 50 patients (12%) had evidence of VTED. The VTED cohort had significantly lower admission and discharge FIM scores than the no-VTED cohort (admission FIM score, 57.2 vs 76.0; discharge FIM score, 66.0 vs 90.1, respectively; P< or =.02). Subjects with VTED had a longer rehabilitation LOS (22.8d vs 13.9d, respectively; P=.02) and higher total rehabilitation charges (28,314 US dollars vs 17,724 US dollars, respectively; P<.05). CONCLUSIONS: In this study, VTED prevalence after LE amputation in a rehabilitation setting was 12%. Subjects with VTED had lower admission and discharge functional status, longer LOS, and higher hospital charges. The utility of screening duplex ultrasound examinations at rehabilitation admission remains unclear.     

Assessment and correlates of self-esteem following stroke using a pictorial measure

OBJECTIVE: To describe the characteristics of a non-verbal measure of self-esteem in a sample of individuals in the acute phase following stroke. DESIGN: Acute-phase stroke survivors (n=156) were administered measures of self-esteem, depression, anxiety, general emotional distress and cognitive functioning during admission to an inpatient stroke rehabilitation unit. MAIN MEASURES: Visual Analogue Self-Esteem Scale (VASES), Geriatric Depression Scale, Adult Manifest Anxiety Scale, Visual Analog Mood Scales, measures of neuropsychological functioning. RESULTS: VASES performance was not related to demographic variables, cognitive functioning, visual acuity, prior stroke or severe visuoperceptual impairment/left visual neglect. The VASES was most related to emotional functioning, with lower self-esteem ratings associated with higher levels of depressive symptoms and general emotional distress. Individuals with right hemisphere stroke tended to endorse lower self-esteem ratings, while aphasic individuals may have misunderstood the intent of the task. CONCLUSIONS: The non-verbal VASES appears to be minimally impacted by potentially invalidating patient factors (e.g. visual acuity, left visual neglect), although its use with patients with severe communication deficits is cautioned. The VASES may prove useful in identifying acute stroke survivors most at risk for emotional dysfunction, and may be useful as a research tool in this population.     

Geriatric depression, medical diagnosis, and functional recovery during acute rehabilitation

OBJECTIVE: To examine and compare the prevalence and functional impact of depressive symptoms for older adult stroke and nonstroke rehabilitation inpatients. DESIGN: Case-control study examining functional outcome using a 2 (stroke, nonstroke) by 2 (depression, no depression) design. SETTING: Urban hospital rehabilitation unit. PARTICIPANTS: A total of 509 rehabilitation inpatients (age, > or = 60 y) were included and grouped by diagnosis of stroke (n=207) and nonstroke (n=302). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Geriatric Depression Scale and FIM instrument. Analysis of covariance procedures examined the impact of depressive symptoms on discharge functional ability controlling for age, sex, admission functional ability, and hospital length of stay. RESULTS: Prevalence of depressive symptoms was similar for stroke (31.8%) and nonstroke (31.5%) and negatively associated with functional ability at discharge for both groups. Overall, the stroke and nonstroke groups did not differ significantly with respect to functional recovery. CONCLUSIONS: Depression, and its impact on acute rehabilitation, is significantly related to functional recovery but does not differ in its frequency or impact for stroke patients. Because depressive symptoms do not appear to discriminate across diagnostic groups, routine screening for depression is recommended for all rehabilitation inpatients.     

Mobility status during inpatient rehabilitation: a comparison of patients with stroke and traumatic brain injury

OBJECTIVES: To compare the mobility status (admission and discharge status, change in status) between patients with stroke and traumatic brain injury (TBI) during inpatient rehabilitation and to determine the relationship between mobility status and outcome variables including length of stay (LOS). DESIGN: Prospective study. SETTING: Free-standing tertiary rehabilitation center. PARTICIPANTS: A total of 210 patients with stroke (n = 136) and TBI (n = 74) consecutively admitted for inpatient rehabilitation. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Clinical Outcome Variable Scale (COVS), a 13-item scale of mobility status (measured on admission and discharge from inpatient rehabilitation), and rehabilitation LOS. RESULTS: With age and time since injury controlled in the model, the TBI group showed a significantly higher mobility status on admission and discharge over the stroke group, but the change (improvement) in mobility status did not differ. The admission mobility status accounted for 61% and 60% of variability of the discharge mobility status for the stroke and TBI groups, respectively. The admission mobility status accounted for 40% and 50% of the variability in rehabilitation LOS for the stroke and TBI groups, respectively. Either the admission mobility status or the physical therapist's prediction of the discharge status could be used to determine the actual discharge mobility status, although the physical therapist's predictions were more accurate than using a statistical model. CONCLUSIONS: The TBI group showed a higher mobility status at admission and discharge from inpatient rehabilitation than the stroke group; however, the rate of improvement (improvement in mobility status per day) did not differ between groups. Admission mobility status using the COVS was an excellent predictor of discharge mobility status and rehabilitation LOS in stroke and TBI patients.     

Nontraumatic spinal cord injury rehabilitation: pressure ulcer patterns, prediction, and impact

OBJECTIVE: To investigate the characteristics, predictors, and consequences of pressure ulcers in patients with nontraumatic spinal cord injury (SCI). DESIGN: Retrospective, 3-year, case series. SETTING: Tertiary medical unit specializing in SCI rehabilitation. PARTICIPANTS: Consecutive sample of 134 adult inpatient referrals with nontraumatic SCI. Patients requiring initial rehabilitation or readmission were included. INTERVENTION: Chart review. MAIN OUTCOME MEASURES: Primary outcome measures were presence of pressure ulcers on admission to rehabilitation, incidence of new pressure ulcers developing during hospitalization, and any complications attributable to pressure ulcers during inpatient rehabilitation. Secondary objectives were to examine the predictability of risk factors for pressure ulcers, to assess the usefulness of a model previously developed for predicting pressure ulcers in patients with chronic SCI, and to estimate the effect of pressure ulcers on rehabilitation of nontraumatic SCI. RESULTS: Prevalence of pressure ulcers among admissions was 31.3% (n=42). Only 2.2% (n=3) of patients developed a new pressure ulcer after admission. The length of stay (LOS) of patients admitted with a pressure ulcer was significantly longer than that of those without a pressure ulcer (geometric mean, 62.3 d for pressure ulcer vs 28.2 d for no pressure ulcer, P=.0001). Many previously identified risk factors for pressure ulcers in SCI patients did not apply to our nontraumatic SCI patients. It is estimated that the inpatient LOS for those patients with a significant pressure ulcer was increased by 42 days. CONCLUSIONS: Pressure ulcers are a common complication for people with nontraumatic SCI who are admitted for rehabilitation, and they have a significant impact on LOS.     

Potential impact of the new medicare prospective payment system on reimbursement for traumatic brain injury inpatient rehabilitation

OBJECTIVE: To evaluate the potential impact of the new Medicare prospective payment system (PPS) on traumatic brain injury (TBI) rehabilitation. DESIGN: Retrospective cohort study of patients with TBI. Patients were assigned to their appropriate case-mix group (CMG) based on Medicare criteria. SETTING: Fourteen urban rehabilitation facilities throughout the United States. PARTICIPANTS: Patients with TBI admitted to inpatient rehabilitation and enrolled in the Traumatic Brain Injury Model Systems from 1998 to 2001 (N=1807). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Cost of inpatient rehabilitation admission, length of stay (LOS), and functional outcomes. RESULTS: The median cost of inpatient rehabilitation for patients with TBI exceeded median PPS payments for all TBI CMGs by 16%. Only 3 of the 14 hospitals received reimbursement under PPS that exceeded costs for their TBI patients. CONCLUSIONS: Compared with current costs, the new Medicare payment system may reimburse facilities significantly less than their costs for the treatment of TBI. To maintain their current financial status, facilities may have to reduce LOS and/or reduce resource use. With a decreased LOS, inpatient rehabilitation services will have to improve FIM efficiency or discharge patients with lower discharge FIM scores.     

Racial/ethnic differences in FIM scores and length of stay for underinsured patients undergoing stroke inpatient rehabilitation

OBJECTIVE: To explore racial/ethnic differences in FIM data from admission to discharge in underinsured patients undergoing inpatient stroke rehabilitation. DESIGN: This is a retrospective analysis of the Uniform Data System for Medical Rehabilitation (UDSMR) database of an inpatient rehabilitation unit of a county hospital in a large urban city. Data included 171 adult patients admitted to the stroke rehabilitation unit between January 2000 and October 2003. Main outcome measures included admission and discharge total FIM score, FIM gain, FIM efficiency, and length of stay (LOS). Data were analyzed using chi analyses, t tests, univariate analysis of variance, binary logistic regression, and hierarchical multiple regression. RESULTS: Data from 68 Hispanic, 83 black, and 20 white patients were included in the study. Univariate tests revealed that race/ethnicity groups differed significantly on admission FIM score (F=5.38, P<0.005), FIM gain (F=4.35, P<0.014), and FIM efficiency (F=3.42, P<0.035). Post hoc pairwise comparisons revealed that Hispanics had lower admission FIM scores than blacks (58.9 vs. 68.9). However, Hispanics had higher FIM gain scores than blacks (26.8 vs. 21.5). Race/ethnicity was not significantly related to age, gender, side of stroke, type of stroke, time from onset of stroke to rehabilitation admission, discharge FIM score, or LOS. Multiple regression analyses revealed that after controlling for all other available factors, race/ethnicity accounted for a significant amount of additional variance in admission FIM score (5.8%) and FIM efficiency (4.6%), but not in discharge FIM score, FIM gain, or LOS. Race/ethnicity was not predictive of discharge disposition. CONCLUSIONS: Differences in functional independence at admission to poststroke rehabilitation and the average daily improvement in function are related, in part, to patients' race/ethnicity. Differences in change in functional independence from admission to discharge (FIM gain) are not related to race/ethnicity once other factors, particularly admission FIM score, are taken into account. Future studies should identify reasons why Hispanics have lower admission FIM scores because demographic and stroke-related variables were not related to ethnicity yet have outcomes similar to blacks and whites at discharge.     

Predicting length of stay in patients admitted to stroke rehabilitation with high levels of functional independence

Purpose.?In Ontario, stroke patients with relatively mild functional deficits are admitted to inpatient rehabilitation programmes. Despite apparently minor impairments, many of these patients remain in rehabilitation for prolonged periods of time. The objective of the present study is to identify variables that predict length of stay (LOS) within this population of high functioning stroke patients.

Methods.?Stroke patients with Functional Independence Measure (FIM?) scores?≥100 admitted to a specialised inpatient rehabilitation programme in Ontario, Canada, from April 2005 to March 2008 were included in this study. Data from the National Rehabilitation Reporting System and chart review were used. Associations with LOS were examined among 25 potential predictor variables using bivariate correlations. Significantly correlated (p <0.002) variables were entered into a multiple linear regression.

Results.?Twenty-four percent (n == 134) of patients admitted during the study period were identified as presenting with mild functional deficits. These patients had a mean admission age of 63.5 (SD 14.6) years, a mean admission FIM score of 109.9 (SD 6.6) and a mean LOS of 22.3 (SD 10.5) days. FIM motor and cognitive subscale scores, Mini Mental State Exam scores and five single items assessing orientation, financial independence, and verbal, written and auditory communication ability were significantly correlated with LOS. The regression model, which included all eight variables, explained 60%% of the variance associated with LOS (r == 0.80).

Conclusions.?For patients admitted to stroke rehabilitation programmes with mild functional impairment, 60%% of the variance in LOS can be explained by a small number of variables indicative of deficits in the areas of motor function, cognition and communication.     

Recovery of functional status after right hemisphere stroke: relationship with unilateral neglect

OBJECTIVE: To evaluate relationships between unilateral spatial neglect and both overall and cognitive-communicative functional outcomes in patients with right hemisphere stroke. DESIGN: Assessment of overall and cognitive-communicative function was conducted on admission to acute rehabilitation, at discharge, and at 3-month follow-up. SETTING: Urban, acute inpatient rehabilitation facility. PATIENTS: Fifty-two consecutive admissions of adult right-handed patients with a single, right hemispheric stroke, confirmed by computed tomography scan. MAIN OUTCOME MEASURES: The FIM instrument and reading comprehension and written expression items of the Rehabilitation Institute of Chicago Functional Assessment Scale(R). RESULTS: Patients made significant functional gains between admission and discharge, and between discharge and follow-up on the FIM. Severity of neglect was correlated with total, motor, and cognitive FIM scores at admission, discharge, and follow-up. Subjects with neglect had significantly more days from onset to admission and a longer length of rehabilitation stay than subjects without neglect. FIM outcomes were significantly different for subject groups with more severe neglect. Both the presence of neglect and its severity were significantly related to functional outcomes for reading and writing. CONCLUSIONS: Patients with neglect show reduced overall and cognitive-communicative functional performance and outcome than patients without neglect. Further studies are needed to explore causal relationships between these factors.
