Neoplastic versus traumatic spinal cord injury: an outcome comparison after inpatient rehabilitation.

OBJECTIVE: To compare outcomes of patients with neoplastic spinal cord compression (SCC) to outcomes of patients with traumatic spinal cord injury (SCI) after inpatient rehabilitation. DESIGN: A comparison between patients with a diagnosis of neoplastic SCC admitted to an SCI rehabilitation unit and patients with a diagnosis of traumatic SCI admitted to the regional Model Spinal Cord Injury Centers over a 5-year period, controlling for age, neurologic level of injury, and American Spinal Injury Association impairment classification. SETTING: Tertiary university medical centers. PATIENTS: Twenty-nine patients with neoplastic SCC and 29 patients with SCI of traumatic etiology who met standard rehabilitation admission criteria. MAIN OUTCOME MEASURES: Acute and rehabilitation hospital length of stay (LOS), Functional Independence Measure (FIM) scores, FIM change, FIM efficiency, and discharge rates to home. RESULTS: Patients with neoplastic SCC had a significantly (p < .01) shorter rehabilitation LOS than those with traumatic SCI (25.17 vs 57.46 days). No statistical significance was found in acute care LOS. Motor FIM scores on admission were higher in the neoplastic group, but discharge FIM scores and FIM change were significantly lower. Both groups had similar FIM efficiencies and community discharges. CONCLUSIONS: Patients with neoplastic SCC can achieve rates of functional gain comparable to those of their counterparts with traumatic SCI. While patients with traumatic SCI achieve greater functional improvement, patients with neoplastic SCC have a shorter rehabilitation LOS and can achieve comparable success with discharge to the community.     

Nontraumatic spinal cord injury: incidence, epidemiology, and functional outcome.

OBJECTIVES: To identify and compare the incidence, demographics, neurologic presentation, and functional outcome of individuals with nontraumatic spinal cord injury (SCI) to individuals with traumatic SCI. DESIGN: A 5-year prospective study. SETTING: Level I trauma center of a Regional SCI Model System. PATIENTS: Two hundred twenty adult SCI admissions. MAIN OUTCOME MEASURES: Demographics, etiology, level and completeness of injury, Functional Independent Measure (FIM) scores. RESULTS: Of SCI admissions, 39% were nontraumatic in etiology (spinal stenosis, 54%; tumor, 26%). Compared to subjects with traumatic SCI, those individuals with nontraumatic SCI were significantly (p < .01) older and were more likely married, female, and retired. Injury characteristics revealed significantly more paraplegia and incomplete SCI within the nontraumatic SCI group (p < .01). Both nontraumatic and traumatic SCI individuals had significant FIM changes from rehabilitation admission to discharge (p < .01). Those with tetraplegia-incomplete nontraumatic SCI had significantly higher admission motor FIM scores and shorter rehabilitation length of stay than in the traumatic group (p < .05). Paraplegic-complete and paraplegic-incomplete nontraumatic SCI subjects had lower discharge motor FIM scores, FIM change, and FIM efficiency than those with traumatic SCI. Similar discharge-to-home rates were noted in both nontraumatic and traumatic SCI groups. CONCLUSIONS: These data suggest that individuals with nontraumatic SCI represent a significant proportion of SCI rehabilitation admissions and, although differing from those with traumatic SCI in demographic and injury patterns, can achieve similar functional outcomes.     

For-Profit and Not-for-Profit Inpatient Rehabilitation in Traumatic Brain Injury: Analysis of Demographics and Outcomes

ObjectiveTo describe differences in characteristics and outcomes of patients with traumatic brain injury by inpatient rehabilitation facility (IRF) profit status.DesignRetrospective database review using the Uniform Data System for Medical Rehabilitation.SettingIRFs.ParticipantsIndividual discharges (N=53,630) from 877 distinct rehabilitation facilities for calendar years 2016 through 2018.InterventionNot applicable.Main Outcome MeasuresPatient demographic data (age, race, primary payer source), admission and discharge FIM, FIM gain, length of stay efficiency, acute hospital readmission from for-profit and not-for-profit IRFs within 30 days, and community discharges by facility profit status.ResultsPatients at for-profit facilities were significantly older (69.69 vs 64.12 years), with lower admission FIM scores (52 vs 57), shorter lengths of stay (13 vs 15 days), and higher discharge FIM scores (88 vs 86); for-profit facilities had higher rates of community discharges (76.8% vs 74.6%) but also had higher rates of readmission (10.3% vs 9.9%).ConclusionsThe finding that for-profit facilities admit older patients who are reportedly less functional on admission and more functional on discharge, with higher rates of community discharge but higher readmission rates than not-for-profit facilities is an unexpected and potentially anomalous finding. In general, older, less functional patients who stay for shorter periods of time would not necessarily be expected to make greater functional gains. These differences should be further studied to determine if differences in patient selection, coding and/or billing, or other unreported factors underlie these differences.     

Impact of early vs delayed admission to rehabilitation on functional outcomes in persons with stroke.

OBJECTIVE: Delayed admission to rehabilitation may result in poorer outcomes by reducing exposure to therapeutic interventions at a time when the brain is primed for neurological recovery. The present study examined the effects of early vs delayed admission on functional outcome and length of stay in patients admitted to a rehabilitation unit for first-ever unilateral stroke. DESIGN: Retrospective chart review. METHODS: Differences in length of rehabilitation stay and functional outcome variables among 435 patients, grouped by interval from stroke event to rehabilitation admission (=30 days vs 31-150 days and 5 additional subgroups) were examined using a multivariate technique. RESULTS: Admission and discharge FIM scores, FIM change and FIM efficiency were significantly higher among early admission patients (p<0.01), while length of stay was significantly longer among delayed admission patients (p<0.01). A significant association was identified between age and admission (p<0.01) and discharge FIM (p<0.01) scores as well as FIM change scores (p=0.017). Subgroup analyses revealed significant differences in FIM scores, FIM change and length of stay between groups of patients admitted 0-15 and 16-30 days (p<0.01) and between patients admitted 16-30 days and 31-60 days post-stroke (p<0.01). No significant differences were noted between patients admitted from 31-60 and 61-90 or 61-90 and 91-150 days. CONCLUSION: Patients admitted to stroke rehabilitation within 30 days of first-ever, unilateral stroke experienced greater functional gains and shorter lengths of stay than those whose admission to rehabilitation was delayed beyond 30 days.     

Gender-related differences in acute rehabilitation lengths of stay, charges, and functional outcomes for a matched sample with spinal cord injury: a multicenter investigation

OBJECTIVE: To examine the effects of gender on length of stay (LOS), treatment costs, and outcomes by using a matched sample of patients with spinal cord injury (SCI). DESIGN: A 2 x (15 x 3) mixed, block design was used retrospectively to analyze the impact of gender on subjects matched for age, American Spinal Injury Association (ASIA) motor impairment classification, and level of neurologic injury. SETTING: Twenty medical centers in the federally sponsored Spinal Cord Injury Model Systems project. PARTICIPANTS: One thousand seventy-four adult patients with SCI admitted between 1988 and 1998 were assessed at acute-care admission, inpatient rehabilitation admission, and inpatient rehabilitation discharge. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: ASIA motor index and FIM instrument admission, discharge, and efficiency scores; rehabilitation LOS and medical care charges; and discharge disposition. RESULTS: Analysis revealed no gender-related differences in FIM motor scores on admission and discharge. No differences in FIM motor efficiencies or daily change were observed. No significant differences were found for ASIA motor scores on acute-care admission and rehabilitation discharge. No differences in acute rehabilitation LOS and charges were observed. No gender-related differences were seen in the likelihood of discharge to an institutional setting. CONCLUSION: Gender was not a significant factor in functional outcome of SCI patients after acute rehabilitation.     

A follow-up study of older adults with traumatic brain injury: taking into account decreasing length of stay

OBJECTIVE: To examine age-related differences in rehabilitation outcomes following traumatic brain injury (TBI). DESIGN: Retrospective collaborative study. SETTING: Patients received acute neurotrauma and inpatient rehabilitation services at 1 of the 17 National Institute on Disability and Rehabilitation Research-designated Traumatic Brain Injury Model Systems (TBIMS) centers. PARTICIPANTS: A sample of 273 older patients (> or =55y) admitted for TBI were taken from the TBIMS National Database. Older patients were matched with subjects 44 years of age or younger, based on severity of injury (Glasgow Coma Scale score, length of coma, intracranial pressure elevations). Due to decreasing length of stay (LOS), only patients admitted from 1996 through 2002 were included. INTERVENTION: Inpatient interdisciplinary brain injury rehabilitation. MAIN OUTCOME MEASURES: Acute care LOS, inpatient rehabilitation LOS, admission and discharge FIM instrument and Disability Rating Scale (DRS) scores, FIM and DRS efficiency, acute and rehabilitative charges, and discharge disposition. RESULTS: One-way analyses of variance demonstrated a statistically significant difference between older and younger patients with respect to LOS in rehabilitation but not for acute care. Total rehabilitative charges, and admission and discharge DRS and FIM scores also showed statistically significant differences between groups. Older patients progressed with significantly less efficiency on both the DRS and FIM scales. Significantly more charges were generated per unit for older patients to improve on the DRS scale, but not the FIM scale. Using chi-square analysis, a statistically significant difference in rate of discharge to home was identified between older (80.5%) and younger (94.4%) patients. CONCLUSIONS: Results in this study are similar to those in earlier studies with smaller sample sizes. Major differences observed include significantly slower and more costly progress in inpatient rehabilitation for older patients with TBI, as well as a significantly lower rate of discharge to community for older patients. However, even with decreasing LOS in both settings, community discharge rate is still encouraging for older patients with TBI.     

Analysis of FIM instrument scores for patients admitted to an inpatient cardiac rehabilitation program

OBJECTIVE: To evaluate in an inpatient cardiac rehabilitation program (a phase IB) whether length of stay (LOS), discharge to home, and improvement in physical function differed between patients with lower and higher degrees of functional independence on admission. DESIGN: A retrospective study. SETTING: A public acute long-term care hospital. PATIENTS: All cardiac rehabilitation patients (N = 143) admitted to the hospital from January 1998 through June 1999. Patients were divided into a higher- and a lower-functioning group by using the admission FIM instrument scores above and below the midpoint of 72. Comparisons in LOS, discharge disposition, and functional gains between these 2 groups were then performed. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: FIM scores, FIM change, FIM gains per week, LOS, and discharge disposition. RESULTS: Total FIM scores at discharge were significantly higher than those on admission (25%, P <.0001). The median value of total FIM gains per week was 7.78 with a stay of 17 days and a home discharge rate of 76%. The higher-functioning group (n = 106) differed from the lower group (n = 37) with shorter stay (15 vs 23d, P <.0001), greater FIM gains per week (8.6 vs 4.8, P =.002), and greater likelihood of discharge to home or community (84% vs 54%, P <.001). The average incremental FIM change in each group was the same. In multivariate analysis, both admission (P =.001) and discharge (P <.001) FIM scores were the best predictors of patients' discharge disposition to home. CONCLUSIONS: Admission FIM scores are important predictors for the clinical course and discharge outcomes of cardiac rehabilitation patients, with those with higher admission FIM scores having a shorter LOS and greater likelihood of discharge to home. The admission FIM scores can help to establish realistic goals.     

Functional outcomes in patients with brain tumor after inpatient rehabilitation: comparison with traumatic brain injury

OBJECTIVE: To compare the functional outcome, length of stay, and discharge disposition of individuals with brain tumor versus those with acute traumatic brain injury. DESIGN: In this study, 78 brain tumor patients were one-to-one matched by location of lesion and age with 78 acute traumatic brain injury patients. Outcome was measured by using the Functional Independence Measure (FIM 228) on admission and discharge. The FIM change and FIM efficiency were also calculated. FIM data were analyzed in three subsets, i.e., activities of daily living, mobility, and cognition. Discharge disposition and rehabilitation length of stay were also compared. RESULTS: Demographic variables of race, marital status, and payer source were comparable for the two groups. No significant difference was found between the brain tumor and the traumatic brain injury populations with respect to total admission FIM, total discharge FIM, and FIM efficiency. The brain injury population had a significantly greater change in FIM. The tumor group had a significantly shorter rehabilitation length of stay and a greater discharge to community rate. CONCLUSIONS: Thus, individuals with brain tumor can achieve comparable functional outcome and have a shorter rehabilitation length of stay and greater discharge to community rate than individuals with brain injury.     

Neoplastic vs. traumatic spinal cord injury: an inpatient rehabilitation comparison

OBJECTIVE: To compare demographics, injury characteristics, and functional outcomes of patients with neoplastic spinal cord compression with those with traumatic spinal cord injuries. DESIGN: A prospective 5-yr comparison was undertaken comparing 34 patients with neoplastic spinal cord compression with 159 patients with traumatic spinal cord injury. RESULTS: Patients with neoplastic spinal cord compression were significantly older, more often female, and unemployed than patients with traumatic spinal cord injury. Neoplastic spinal cord compression presented more often with paraplegia involving the thoracic spine, and injuries were more often incomplete compared with traumatic spinal cord injury. Patients with neoplastic spinal cord compression had a significantly shorter rehabilitation length of stay compared with those with traumatic spinal cord injury. The neoplastic group had significantly lower FIM change scores. Both groups had similar FIM efficiencies and discharge to home rates. CONCLUSIONS: Patients with neoplastic spinal cord compression have different demographic and injury characteristics but can achieve comparable rates of functional gains as their traumatic spinal cord injury counterparts. Although patients with traumatic injuries achieve greater functional improvement, patients with neoplasms have a shorter rehabilitation length of stay and comparable FIM efficiencies and home discharge rates.     

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.     

Association of hemoglobin levels, acute hemoglobin decrease, age, and co-morbidities with rehabilitation outcomes after total knee replacement

OBJECTIVE: A study was undertaken to assess the association of preoperative and postoperative hemoglobin levels with rehabilitation outcomes, age, and selected co-morbidities DESIGN: Charts of 49 patients admitted to rehabilitation after total knee arthroplasty due to degenerative joint disease were reviewed. Outcome measures included rehabilitation admission and discharge motor FIMtrade mark scores, motor FIM gain, and rehabilitation length of stay. RESULTS: Patients with higher preoperative hemoglobin levels had higher rehabilitation admission motor FIM scores (r=0.38, P<0.01) and lower motor FIM gains (r=-0.45, P<0.001). Patients who had higher hemoglobin levels at rehabilitation admission had higher admission motor FIM scores and shorter length of stay. Patients with diabetes had lower preoperative hemoglobin levels. Patients with hypertension had longer length of stay. Older patients had lower admission and discharge motor FIM scores and longer length of stay. CONCLUSIONS: Patients admitted to rehabilitation after total knee replacement have the potential to improve motor function, regardless of their preoperative and rehabilitation admission hemoglobin levels and the decrease in hemoglobin levels. However, those admitted to rehabilitation with lower hemoglobin levels, those with lower admission motor FIM scores, those who are older, and those who have hypertension may expect longer hospital stays to reach their functional goals.     

Rehabilitation outcomes after infection-related spinal cord disease: a retrospective analysis

OBJECTIVES: To compare injury characteristics, demographics, and functional outcomes of patients with infection-related spinal cord disease (IR-SCD) vs. those with traumatic spinal cord injury (SCI). DESIGN: A 10-yr retrospective review of 34 consecutive patients with IR-SCD admitted to an SCI rehabilitation unit at a Level 1 tertiary university medical center. Outcome measures included length of stay (LOS), FIM motor scores, and home discharge rates. RESULTS: The cause of IR-SCD was most often spinal epidural abscess secondary to Staphylococcus aureus (74%). Weakness (90%) and neck/back pain (84%) were the most frequent initial admitting symptoms. Identifiable risk factors included history of recent infection (42%), diabetes mellitus (32%), and intravenous drug abuse (26%). SCD-related complications most commonly included pain (81%), urinary tract infection (52%), and spasticity (45%). When compared with traumatic SCI (n = 560), patients with IR-SCD comprised significantly less of the SCI/D rehabilitation admissions (3% vs. 61%), were older (53 vs. 40 yrs), and more often female (35% vs. 16%). Injuries were more commonly located in the thoracic region (48% vs. 38%). Patients with IR-SCD more often had incomplete injuries (94% vs. 57%). Thirty-two percent of IR-SCD patients had improvements in AIS impairment scale classification. LOS was longer on acute care (25 vs. 16 days), but similar on rehabilitation (36 vs. 34 days), and with lower FIM motor changes (16.2 vs. 22.8) during rehabilitation. Patients with IR-SCD were less often discharged to home (56% vs. 75%). CONCLUSIONS: Patients with infection-related SCD comprise a significant subset of SCI/D rehabilitation admissions and have differing demographic and injury characteristics compared with traumatic SCI. Despite less-severe injury characteristics and similar rehabilitation LOS, they achieve lower functional improvements and are less often discharged home, underscoring the importance of patient/family education and discharge planning.     

Outcomes in total knee arthroplasty patients after inpatient rehabilitation: influence of age and gender

OBJECTIVES: To examine age and gender effects on outcomes after inpatient rehabilitation in primary total knee arthroplasty (TKA) and revision TKA patients. DESIGN: This retrospective, comparative study was conducted in a 50-bed, university-affiliated rehabilitation hospital. Patients included primary TKA patients (n = 286) and revision TKA patients (n = 138) placed into one of three age brackets: <60 yrs, 60-70 yrs, or >70 yrs. Measurements included length of stay (LOS), FIM scores, hospital charges, and discharge disposition location. RESULTS: FIM scores improved from admission to discharge in both primary and revision patients (P = 0.015). LOS was shorter in primary than revision patients (8.3 vs. 10.4 days, P = 0.001), and the LOS was longest in patients >70 yrs compared with those <60 or 60-70 yrs (10.6 vs. 8.7 and 8.8 days, respectively; P = 0.004). FIM efficiency was greater in primary than in revision TKA patients (3.68 vs. 2.77 points/day, P = 0.001), and greater for men than women in each age bracket regardless of TKA type (3.68 vs. 2.78 points/day, P = 0.001). Total hospital charges were lower for men than women for both TKA types ($9,656 +/- 823 vs. $11,544 +/- 1,359; P = 0.015), and were highest in patients >70 yrs of age (P = 0.015). CONCLUSIONS: Primary and revision TKA patients make improvements in functional independence during inpatient rehabilitation. Although FIM gains were similar among age and gender groupings, FIM efficiency is lowest in women. Despite similar daily hospital costs among the groups, slower progress with functional gains (decreased FIM efficiency) increases the LOS and total hospital charges, especially in older women.     

Effect of co-morbid traumatic brain injury on functional outcome of persons with spinal cord injuries

OBJECTIVE: This study was undertaken to determine if persons who sustain a spinal cord injury (SCI) and co-morbid brain injury (dual diagnosis [DDS]) evidence smaller functional gains and experience significantly longer rehabilitation lengths of stay than persons with only an SCI. DESIGN: This retrospective comparison study was performed at a 100-bed rehabilitation hospital specializing in acute SCI and traumatic brain injury rehabilitation. Summary scale outcome data of persons who sustained an SCI were compared with outcome data of a group of persons with a DDS. Comparisons were established by matching groups principally on level of SCI and admission Motor FIM trade mark score and secondarily on education, sex, and age. Outcome measures included admission Motor and Cognitive FIM score, discharge Motor and Cognitive FIM score, Motor and Cognitive FIM change, length of stay, and rehabilitation charges. RESULTS: Persons with a DDS evidenced a significantly more impaired Cognitive FIM score at admission and discharge from rehabilitation. Persons with a DDS also achieved a significantly lower Motor FIM change than persons with SCI. There were no significant differences between DDS and SCI groups regarding Cognitive FIM change, length of stay, or rehabilitation charges. Injury severity as defined by the Glasgow Coma Scale or intracranial lesions did not predict response to treatment in the DDS group. CONCLUSION: Persons with a DDS achieved smaller functional gains during rehabilitation than peers with SCI. Brain injuries seem to limit functional gains, although the relationship between brain injury severity and functional change is not linear. Prospective studies are needed to identify factors limiting functional gains in rehabilitation and assist in developing specific treatment programs for persons with SCI and brain injury.     

Paraplegia after aortic aneurysm repair versus traumatic spinal cord injury: functional outcome, complications, and therapy intensity of inpatient rehabilitation

Yokoyama O, Sakuma F, Itoh R, Sashika H. Paraplegia after aortic aneurysm repair versus traumatic spinal cord injury: functional outcome, complications, and therapy intensity of inpatient rehabilitation.

Objective

To compare outcomes, complications, and therapy intensity of inpatient rehabilitation in patients with paraplegia caused by spinal cord injury associated with aortic aneurysm repair (SCI-AA) versus patients with traumatic spinal cord injury (SCI).

Design

Case-controlled study.

Setting

SCI unit in a rehabilitation center.

Participants

Seventeen patients with SCI-AA and 17 patients with traumatic SCI.

Intervention

Standard rehabilitation therapy for SCI.

Main Outcome Measures

Length of stay (LOS) in acute and rehabilitation hospitals; FIM instrument scores; FIM change; FIM efficiency; complications; therapy intensity; and ambulatory state and return to community at discharge.

Results

No significant differences were noted in acute and rehabilitation LOS and admission FIM scores. Discharge FIM scores, FIM change, and FIM efficiencies were significantly lower in the SCI-AA group, which had many complications related to AA and SCI. Intensity of rehabilitation sports therapy in the SCI-AA group was significantly lower than that of the traumatic SCI group, but total therapy intensity did not differ significantly. Both had similar rates of return to ambulatory state and discharge to the community.

Conclusions

SCI-AA patients had many complications that interfered with rehabilitation therapy, and could not achieve functional gains comparable to those with traumatic SCI. However, both groups achieved comparable success with return to ambulatory state and discharge to the community.     

A multicenter investigation of age-related differences in lengths of stay, hospitalization charges, and outcomes for a matched tetraplegia sample.

OBJECTIVE: To examine the effects of age at injury on lengths of stay, treatment costs, and outcomes using a matched sample of tetraplegic spinal cord injury (SCI) patients. DESIGN: Differences were examined by separating the sample into three age categories (18 to 34, 35 to 64, and 65+ years old) matched for American Spinal Injury Association (ASIA) Motor Impairment Classification and level of neurologic preservation bilaterally. Analysis of variance was used to examine age group differences for lengths of stay, medical expenses, and functional outcome. SETTING: Sixteen medical centers in the federally sponsored Spinal Cord Injury Model Systems Project. PARTICIPANTS: Three hundred seventy-five adult patients with tetraplegic SCI admitted between 1988 and 1996 were assessed at acute care admission, inpatient rehabilitation admission, and inpatient rehabilitation discharge. MAIN OUTCOME MEASURES: ASIA Motor Index and Functional Independence Measure (FIM) admission, discharge, and efficiency scores; acute care and rehabilitation lengths of stay and medical care charges; and discharge disposition. RESULTS: Analyses revealed equivalent lengths of stay and charges for all age groups. There were no age-related differences in ASIA and FIM Motor scores at acute care and inpatient rehabilitation admission. Younger patients' scores on the FIM Motor subscale improved significantly more than did middle and older patients'. The two younger groups of patients had a more significant improvement than did older patients, as indicated by ASIA Motor Index scores. When taking lengths of stay into account, the FIM motor scores of the youngest group of patients improved more quickly than those of the two older groups. Furthermore, the younger and middle age groups demonstrated greater treatment efficiency than the older patient group based on ASIA Motor Index score ratios. Younger patients were least likely to be discharged to institutional settings. CONCLUSIONS: Along with neurologic and functional status, age should be considered when formulating treatment plans and prognostic statements. For older patients, alternative rehabilitation settings with lower-intensity treatment and lower charges may prove to be a more efficacious use of resources.     

Poster 7: Impact of balance deficits after traumatic brain injury on inpatient rehabilitation functional outcome: a multicenter study

Objective: To evaluate how sitting and standing balance ratings of patients with traumatic brain injury (TBI) on admission to rehabilitation impacts functional outcome, rehabilitation charges, and rehabilitation length of stay (LOS). Design: Multicenter analysis of consecutive admissions to designated Traumatic Brain Injury Model Systems (TBIMS). Setting: TBIMS centers. Participants: 908 adults with TBI were included in the study. Interventions: Not applicable. Main Outcome Measure: FIM™ instrument admission and discharge scores, FIM change and efficiency; rehabilitation LOS and charges; and discharge disposition. Results: Persons with grossly impaired sitting balance on admission to rehabilitation had lower discharge FIM scores and greater rehabilitation charges than those with normal or mildly impaired sitting balance. Persons with mildly impaired sitting balance had lower discharge FIM scores and greater rehabilitation charges than those with normal sitting balance. Subjects with grossly impaired standing balance compared with normal or mildly impaired standing balance had greater rehabilitation charges and LOS and lower discharge FIM scores and FIM efficiency. Subjects with grossly impaired balance on admission to rehabilitation had significantly lower motor FIM items compared with those who had normal or mildly impaired balance. Subjects with grossly impaired sitting balance were discharged from rehabilitation to someplace other than their home more than twice as often as those with normal sitting balance (11.7% vs 23.3%). Subjects with grossly impaired standing balance were discharged from rehabilitation to someplace other than their home more than 3 times as often as subjects with normal standing balance (6.7% vs 21.5%). Conclusion: In patients with TBI, sitting and standing balance ratings on admission to rehabilitation are useful indicators of functional impairment and not returning home at discharge from rehabilitation.     

Influence of medical comorbidities and complications on FIM change and length of stay during inpatient rehabilitation

OBJECTIVE: This study was performed to evaluate the influence of medical problems on functional outcome measures of patients admitted for comprehensive inpatient rehabilitation. DESIGN: In this retrospective database review of patients, demographic information, length of stay, FIM scores at admission and discharge, and FIM efficiency were collected and analyzed. Preexisting comorbidities and acute medical complications of all patients were identified, tabulated, and analyzed. RESULTS: A total of 175 patients were categorized into three major groups. In the postorthopedic surgery group, the presence of preexisting medical comorbidities did not significantly affect admission or discharge FIM scores. In contrast, traumatic brain injury patients with preexisting medical comorbidities had a tendency to be admitted and discharged with lower FIM scores. However, traumatic brain injury patients with acute medical complications still made reasonable functional improvement during their extended stay, so that their FIM efficiency was adequately maintained. In the cerebrovascular accident group, almost all patients had preexisting medical issues. CONCLUSIONS: The rehabilitation population is diverse, and functional outcome measures for distinct disease entities may be differentially affected by factors such as preexisting medical comorbidities and acute medical complications. Except for life-threatening medical emergencies, rehabilitation patients may benefit by staying on the acute rehabilitation unit, where both medical management and a comprehensive rehabilitation program are provided with continuity.     

Rehabilitation of postcardiac surgery stroke patients. Progress,outcomes, and comparisons with other stroke patients

OBJECTIVE: To examine the demographics, progress, and functional outcomes of all postcardiac surgery stroke patients admitted to the rehabilitation unit of an acute, tertiary general hospital over a 5-yr period and to compare this cohort with an age-matched control group of other stroke patients admitted during the same period. DESIGN: A retrospective chart review of 47 postcardiac surgery stroke and a matched control group of other stroke patients admitted to the rehabilitation unit. RESULTS: The mean age of the postcardiac surgery stroke patients was 70.80 +/- 8.37 yr, with 60% of patients being male. Their average length of stay on the rehabilitation unit was 15.64 +/- 11.96 days. Mean admit FIM total score was 65.64 +/- 16.33, with a discharge FIM total score of 86.77 +/- 18.93. Mean admit FIM motor score was 41.47 +/- 9.45, with a discharge FIM motor of 60.74 +/- 13.20. The other stroke group had significantly greater admit FIM total (P = 0.03), admit motor (P = 0.001), and discharge motor (P = 0.025) scores. FIM efficiency and motor and cognitive gains were comparable between the two groups. Length of stay on the rehabilitation unit was approximately 2 days less (P = 0.224) for the other stroke cohort. Ultimately, 39 (83%) of the postcardiac surgery stroke patients were discharged to the community compared with 45 (96%) of the other stroke patients (P = 0.19). CONCLUSIONS: The majority of postcardiac surgery stroke patients successfully completed a comprehensive inpatient rehabilitation program. They had lower admit FIM total scores and admit and discharge FIM motor scores than the other stroke group and were almost as likely to ultimately return to the community.
