Nontraumatic vs. traumatic spinal cord injury: a rehabilitation outcome comparison

OBJECTIVE: Nontraumatic spinal cord injury (SCI) represents a significant proportion of individuals admitted for SCI rehabilitation; however, there is limited literature regarding their outcomes. As our society continues to age and nontraumatic injuries present with greater frequency, further studies in this area will become increasingly relevant. The objective of this study was to compare outcomes of patients with nontraumatic SCI with those with traumatic SCI after inpatient rehabilitation. DESIGN: A longitudinal study with matched block design was used comparing 86 patients with nontraumatic SCI admitted to a SCI rehabilitation unit and 86 patients with traumatic SCI admitted to regional model SCI centers, controlling for age, neurologic level of injury, and American Spinal Injury Association impairment classification. Main outcome measures included acute and rehabilitation hospital length of stay, FIM scores, FIM change, FIM efficiency, rehabilitation charges, and discharge-to-home rates. RESULTS: Results indicate that when compared with traumatic SCI, patients with nontraumatic SCI had a significantly (P < 0.01) shorter rehabilitation length of stay (22.38 vs. 41.35 days) and lower discharge FIM scores (57.3 vs. 65.6), FIM change (18.6 vs. 31.0), and rehabilitation charges ($25,050 vs. $64,570). No statistical differences were found in acute care length of stay, admission FIM scores, FIM efficiency, and community discharge rates. CONCLUSIONS: The findings indicate that patients with nontraumatic SCI can achieve rates of functional gains and community discharge comparable with traumatic SCI. Whereas patients with traumatic SCI achieved greater overall functional improvement, patients with nontraumatic SCI had shorter rehabilitation length of stay and lower rehabilitation charges. These findings have important implications for the interdisciplinary rehabilitation process in the overall management and outcome of individuals with nontraumatic SCI.     

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.     

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.     

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.     

Poster 17: Is length of stay associated with spinal cord injury functional outcome at discharge from acute rehabilitation?

Objective: To determine whether rehabilitation length of stay (LOS) is associated with discharge motor function for persons with spinal cord injury (SCI). Design: Longitudinal. Setting: Spinal Cord Injury Model Systems center. Participants: 920 persons with traumatic, complete SCI enrolled in the Spinal Cord Injury National Database, with levels of injury (LOI) at C5, C6, C7, and T1-5; and inpatient rehabilitation discharge dates between 1989 and 1992 (“early”) and 1999 and 2002 (“late”). Interventions: Not applicable. Main Outcome Measures: FIM™ instrument at rehabilitation discharge. Results: For all LOI groups, the late group had a LOS shorter than the early group, with the largest difference in the C7 group: 107 days (early) versus 59 days (late). FIM motor scores at rehabilitation discharge also differed significantly for the C5, C7, and T1-5 LOI groups. For each of these LOIs, the late group was discharged with lower FIM motor scores; the largest difference was again noted for the C7 group, which had FIM motor scores of 51.9 (early) versus 40.7 (late). Conclusions: Decreased inpatient rehabilitation LOS was associated with decreased function at rehabilitation discharge. Persons with C7-level SCI were the most affected group; this group had the largest decrease in LOS and motor FIM score.     

Outcomes of early surgical management versus late or no surgical intervention after acute spinal cord injury

OBJECTIVE: To compare neurologic, medical, and functional outcomes of patients with acute spinal cord injury (SCI) undergoing early (<24 h and 24-72 h) and late (>72 h) surgical spine intervention versus those treated nonsurgically. DESIGN: Retrospective case series comparing outcomes by surgical and nonsurgical groups during acute care, rehabilitation, and at 1-year follow-up. SETTING: Multicenter National Spinal Cord Injury Database. PARTICIPANTS: Consecutive patients with acute, nonpenetrating, traumatic SCI from 1995 to 2000, admitted in the first 24 hours after injury. Surgical spinal intervention was likely secondary to nature of injury and the need for spinal stabilization. Interventions Not applicable. MAIN OUTCOME MEASURES: Changes in neurologic outcomes (motor and sensory levels, motor index score, American Spinal Injury Association [ASIA] Impairment Scale [AIS]), medical complications (pneumonia and atelectasis, deep vein thrombosis and pulmonary embolism, pressure ulcers, autonomic dysreflexia, rehospitalization), and functional outcomes (acute and rehabilitation length of stay [LOS], hospital charges, FIM instrument score, FIM motor efficiency scores). RESULTS: Subjects in the early surgery group were more likely ( P <.05) to be women, have paraplegia, and have SCI caused by motor vehicle collisions. The nonsurgical group was more likely ( P <.05) to have an older mean age and more incomplete injuries. ASIA motor index improvements (from admission to 1-y follow-up) were more likely ( P <.05) in the nonsurgical groups, as compared with the surgical groups. Those with late surgery had significantly ( P <.05) increased acute care and total LOS and hospital charges along with higher incidence of pneumonia and atelectasis. No differences between groups were found for changes in neurologic levels, AIS grade, or FIM motor efficiency. CONCLUSIONS: ASIA motor index improvements were noted in the nonsurgery group, though likely related to increased incompleteness of injuries within this group. Early versus late spinal surgery was associated with shorter LOS and reduced pulmonary complications, however, no differences in neurologic or functional improvements were noted between early or late surgical groups.     

Medical rehabilitation length of stay and outcomes for persons with traumatic spinal cord injury--1990-1997

OBJECTIVES: To describe changes in acute and rehabilitation length of stay (LOS) for persons with traumatic spinal cord injury (SCI), describe predictors of LOS, and explore year-1 anniversary medical and social outcomes. DESIGN: Longitudinal, exploratory study of patients with SCI. SETTING: Eighteen Model Spinal Cord Injury Centers across the United States. SAMPLE: A total of 3,904 persons discharged from the Model Systems between 1990 and 1997 who had follow-up interviews at 1 year postinjury. MAIN OUTCOME MEASURES: Rehabilitation LOS; injury anniversary year-1 presence of pressure ulcers; incidence of rehospitalization; community or institutional residence; and days per week out of residence. RESULTS: Acute rehabilitation LOS declined from 74 days to 60 days. Discharges to nursing homes and rehospitalizations increased between 1990 and 1997. Linear regression showed that lower admission motor Functional Independence Measure (FIM) scores, year of discharge from the Model System, method of bladder management, tetraplegia, race, education, marital status, discharge disposition, and age were related to longer LOS. At first anniversary, logistic regressions revealed that lower discharge motor FIM, injury level, and age were related to the presence of pressure ulcers, rehospitalization, residence, and time spent out of residence. Of those discharged to nursing homes, 44% returned to home by year 1, and these individuals had higher functional status and were younger. DISCUSSION: High functional status is associated with shorter LOS, discharge to the community, and time spent out of residence, indicating efficiency in the system. For 44.4% of individuals one or more of the following outcomes were observed by first year anniversary: rehospitalization; residing in a skilled nursing facility; having pressure ulcers; or infrequently leaving one's residence.     

Effects of gender on neurologic and functional recovery after spinal cord injury

OBJECTIVE: To assess gender differences in neurologic and functional outcome measures in persons with spinal cord injury (SCI). DESIGN: Case series. SETTINGS: Model Spinal Cord Injury Systems (MSCIS) throughout the United States. PARTICIPANTS: People (N=14,433) admitted to an MSCIS within 30 days of injury. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Improvement in American Spinal Injury Association (ASIA) motor index score, ASIA Impairment Scale, level of injury, and FIM instrument scores after SCI. RESULTS: When examining subjects grouped by severity of injury, changes in ASIA motor index total scores, from system admission to 1-year anniversary, were significantly greater for women than men with either complete ( P =.035) or incomplete ( P =.031) injuries. Functional comparison of men and women, using the FIM motor subscale, revealed that men had higher FIM motor scores at rehabilitation discharge among those with motor-complete injuries, except for those with C1-4 and C6 neurologic levels. Women with motor-incomplete high tetraplegia (C1-4 levels) had higher discharge FIM motor scores than did similarly afflicted men. There were no significant differences in FIM motor scores among men and women with other levels of motor incomplete SCI. CONCLUSIONS: Gender differences in SCI were seen in several areas. Women may have more natural neurologic recovery than men; however, for a given level and degree of neurologic injury, men tend to do better functionally than women at time of discharge from rehabilitation. Future prospective study of the effects of estrogen on neurologic recovery and the effects of gender on functional potential are recommended.     

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.     

Predicting walking at discharge from inpatient rehabilitation after a traumatic spinal cord injury

OBJECTIVE: To investigate how injury level and American Spinal Injury Association Impairment Scale (AIS) grade at rehabilitation admission are related to walking at discharge after traumatic spinal cord injury (SCI). DESIGN: Retrospective study. SETTING: Comprehensive rehabilitation hospital. PARTICIPANTS: A total of 343 adult inpatients with traumatic SCI. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: FIM instrument walking rating of 3 (moderate assistance) or higher at discharge. RESULTS: Significantly more subjects admitted with AIS grade C (28.3%) than AIS grade A or B injuries (0.9%) walked at discharge. Significantly more subjects admitted with AIS grade D (67.2%) than AIS grade C (28.3%) injuries walked at discharge. Level of injury did not significantly affect walking after AIS grade C or D injuries. Being 50 years or older had a significant negative affect on walking in subjects with AIS grade D but not AIS grade C injuries. CONCLUSIONS: Admission AIS grades give information about walking for treatment and discharge planning during acute inpatient rehabilitation, including the following: (1) patients admitted with AIS grade C injuries should not be considered functionally complete when predicting walking (FIM score > or = 3; no more than moderate assistance) at discharge, (2) level of injury does not affect walking for those with AIS grade C or D injuries, and (3) being 50 years or older has a significant negative affect on walking in subjects with AIS grade D but not AIS grade C injuries.     

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.     

Testosterone replacement therapy and motor function in men with spinal cord injury: a retrospective analysis

OBJECTIVE: To evaluate motor function in men with spinal cord injury (SCI) given testosterone replacement therapy (TRT). DESIGN: American Spinal Injury Association (ASIA) rehabilitation discharge motor index scores were compared between men with SCI given TRT (testosterone cypionate, 200 mg, monthly; n = 50) and a comparison group (n = 480) in a retrospective study. Covariates included admission motor and FIM scores, level of injury (paraplegia/tetraplegia), days since injury, and age. RESULTS: ASIA discharge motor scores for ASIA impairment scale grades C and D were significantly different (P < 0.05) in men with incomplete SCI given TRT, relative to the comparison group. The covariate-adjusted mean discharge score for the TRT group was higher than for the comparison group. There were no significant differences in discharge FIM scores (P = 0.34) for men with incomplete injuries and no differences in the adjusted discharge ASIA motor scores (P = 0.92) or adjusted discharge FIM scores (P = 0.16) for men with complete injuries. CONCLUSION: The data support a relationship between TRT and strength gains in men with residual motor function after SCI. Prospective studies are necessary to validate these findings.     

Metric properties of the ASIA motor score: subscales improve correlation with functional activities

OBJECTIVE: To apply item response theory (IRT) methods to neurologic and functional scales to determine the value of using American Spinal Injury Association (ASIA) motor subscores and ability estimates, rather than total ASIA motor scores, to predict motor FIM instrument scores. DESIGN: Secondary analysis of prospectively collected data. SETTING: Model Spinal Cord Injury Systems centers. PARTICIPANTS: People with traumatic spinal cord injury (SCI) (N=4338) discharged from inpatient rehabilitation between January 1, 1994, and March 31, 2003. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Total discharge motor FIM scores, FIM subscale scores, and IRT-derived ability estimates of motor FIM scores. RESULTS: Use of separate ASIA upper-extremity and lower-extremity motor scores improved prediction of motor FIM scores over that of total ASIA motor score (R(2) for motor FIM score, .71 vs .59). Use of IRT-based ability estimates derived by applying a 2-parameter graded response model to the raw scores, however, did not improve prediction of motor FIM scores above that of the ASIA motor subscale scores. CONCLUSIONS: Consistent with the metric properties of the ASIA motor score, and with recent models of disablement, impairment in SCI is more accurately characterized by using separate ASIA upper- and lower-extremity motor scores than by using a single motor score. Use of subscores for impairment should improve prediction of functional abilities and enhance more complex models of disability.

Early rehabilitation effect for traumatic spinal cord injury

OBJECTIVE: To determine the natural course of traumatic spinal cord injury (SCI) and the effect of early rehabilitation on it. DESIGN: A retrospective, multicenter study. SETTING: Sixteen Rosai hospitals and 1 medical school. PARTICIPANTS: One hundred twenty-three SCI patients (104 men, 19 women; mean age, 48.8 +/- 17.7yr) enrolled. INTERVENTIONS: Dividing the subjects into an early rehabilitation group and a delayed group; differences were ensured by international classification of SCI. MAIN OUTCOME MEASURES: Using the American Spinal Injury Association (ASIA) classifications, the motor recovery rate (MRR) was defined as (ASIA motor score at discharge - ASIA motor score at admission)/(100 - ASIA motor score at admission). The regression lines for FIM instrument score and ASIA motor score were determined for 6 subgroups (early or delayed tetraplegia, central cord injury, paraplegia) by the MRR staging. The regression lines for physical or cognitive FIM score and ASIA motor score were also determined for 6 subgroups. RESULTS: Three stages were obtained: acute stage: 2 weeks postinjury; recovery stage: 2 weeks to 6 months postinjury; and chronic stage: more than 6 months postinjury. Regression lines showed that rehabilitation improved physical functional independence for ASIA motor score, especially in the early rehabilitation subgroups. There was no correlation between cognitive FIM score and ASIA motor score in 6 subgroups. CONCLUSION: Early SCI rehabilitation contributes to good physical activities of daily living for motor function.

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.     

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.
