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.

Macciocchi S, Seel RT, Warshowsky A, Thompson N, Barlow K. Co-occurring traumatic brain injury and acute spinal cord injury rehabilitation outcomes.ObjectiveTo determine the impact of co-occurring traumatic brain injury (TBI) on functional motor outcome and cognition during acute spinal cord injury (SCI) rehabilitation.DesignProspective, longitudinal cohort.SettingSingle-center National Institute of Disability and Rehabilitation Research SCI Model System.ParticipantsPersons aged 16 to 59 years (N=189) admitted for acute SCI rehabilitation during the 18-month recruitment window who met inclusion criteria.InterventionsNot applicable.Main Outcome MeasuresFIM Motor Scale (Rasch transformed) and acute rehabilitation length of stay (LOS).ResultsIn the tetraplegia sample, co-occurring TBI was not related to FIM Motor Scale scores or acute rehabilitation LOS despite having negative impacts on memory and problem solving. Persons with paraplegia who sustained co-occurring severe TBI had lower admission and discharge FIM Motor Scale scores and longer acute rehabilitation LOS than did persons with paraplegia and either no TBI or mild TBI. Persons with paraplegia and severe TBI had lower functional comprehension, problem solving, and memory and impairments on tests of processing speed compared with persons with paraplegia and no TBI, mild TBI, and moderate TBI. Persons with paraplegia and co-occurring mild and moderate TBI had equivalent acute rehabilitation motor outcomes and cognitive functioning compared with persons with paraplegia and no TBI.ConclusionsThis study provides evidence that persons aged 16 to 59 years with paraplegia and co-occurring severe TBI had worse motor outcomes and longer acute rehabilitation LOS than did persons with paraplegia and no TBI. Impairments in processing speed, comprehension, memory, and problem solving may explain suboptimal motor skill acquisition. Research with larger samples is required to determine whether mild and moderate TBI impact acute rehabilitation motor outcomes and LOS.     

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.     

Poster 27: Acute rehabilitation: comparison of functional outcomes of liver transplant and stroke patients

Objectives: To determine the functional outcomes of liver transplant patients with acute rehabilitation and to compare outcomes with those of stroke patients. Design: Retrospective study. Setting: Acute rehabilitation unit in a university hospital. Participants: Inpatient charts of 13 liver transplant patients and 13 stroke patients were reviewed. Interventions: The charts of 13 patients who underwent inpatient rehabilitation after liver transplants were reviewed to assess their functional gains. Their functional progress was measured on the FIM™ instrument at admission, weekly, and at discharge. Progress was compared with 13 age-matched stroke patients. Main Outcome Measures: FIM efficiency ratio of liver transplant patients was obtained by dividing the total FIM gain by the length of stay (LOS). This ratio was compared with that of the stroke patients. Results: The average age of the liver transplant patients was 56 years and that of the stroke patients was 55 years. The average admission FIM scores for transplant patients was 50 and discharge FIM scores was 76, compared with 51 and 72, respectively, for the stroke patients. The average LOS of the transplant patients was 20 days; it was 21 days for the stroke patients. The efficiency ratio was 1.35 for transplant patients and 1.33 for the stroke patients. The Student t test, with 24 degrees of freedom, showed no statistically significant differences between the liver transplant and stroke patients for their average admission and discharge FIM scores and efficiency ratios. There was also no significant difference in the average LOS. Conclusion: Patients with liver transplants made functional gains similar to those of stroke patients of similar age.     

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.     

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.     

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.

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.     

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.     

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.     

Characteristics and functional outcomes of brain injury caused by physical assault in Canada: a population-based study from an inpatient rehabilitation setting

Abstract

Purpose: To investigate the characteristics and inpatient rehabilitation outcomes of persons who sustained a traumatic brain injury (TBI) resulting from physical assault – a form of intentional TBI – and compare these outcomes to those of persons with TBI resulting from other aetiologies. Method: A prospective population-based cohort study using inpatient rehabilitation data from Canadian population-based administrative databases for the fiscal years 2001–2006. Outcome measures were measures of functional independence (motor and cognitive), as measured by the FIM? Instrument, and discharge destinations. Results: Characteristics associated with intentional TBI were being male, younger in age and unemployed; living alone and having a greater likelihood of alcohol/drug abuse prior to admission. The intentional TBI group showed poorer total functional gains at discharge from inpatient rehabilitation. Multivariate regression analyses showed that persons with intentional injury were less likely to be discharged home. Conclusions: Persons with TBI from physical assault are a distinct clinical group in Canadian inpatient rehabilitation settings. These findings can support clinicians in determining proper assessment, management, discharge planning and post-rehabilitation care that target specific needs of persons with TBI resulting from physical assault.

• Implications for Rehabilitation

• Clinicians should have appropriate training to properly assess the mental health status of this patient group.

• Inpatient rehabilitation facilities should be prepared to provide services targeting psychosocial, substance abuse and interpersonal relationship issues to persons with a TBI from physical assault while patients are still within a hospital setting.

• Follow-up clinical care and community support services are warranted for those with intentional TBIs, including provision of occupational rehabilitation services, such as vocational rehabilitation.

• The discharge team should be responsible for ensuring appropriate discharge to community in the absence of family or other advocates on behalf of the patient.

     

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.     

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.     

A preliminary examination of the CMS eligibility criteria in total-joint arthroplasty

OBJECTIVE: To analyze inpatient rehabilitation outcomes in total-knee arthroplasty (TKA) and total-hip arthroplasty (THA) patients using the 2004 Medicare 75% rule criteria. DESIGN: This retrospective study compared outcomes in unilateral TKA (UTKA), bilateral TKA (BTKA), and THA after interdisciplinary inpatient rehabilitation (n = 867). Patients were separated into three comparison pairs: 1) UTKA or BTKA, 2) age <85 yrs or > or =85 yrs, and 3) body mass index (BMI) <50 or > or =50 kg/m. Length of stay (LOS), functional independence measure (FIM) scores (total, motor, and cognitive), hospital charges, FIM efficiency, and discharge disposition were analyzed. RESULTS: BTKA improved total FIM score more than UTKA (43 vs. 38%; P = 0.039). TKA with BMI > or =50 kg/m had similar admission and discharge FIM motor scores compared with BMI <50 kg/m (P > 0.05). TKA patients > or =85 yrs had lower admission FIM scores, longer LOS (11.3 vs. 9.4 days), and 22% higher total charges than TKA patients younger than 85 yrs (P = 0.042). THA patients > or =85 yrs had 6-10% lower total FIM, FIM motor, and FIM cognition scores and were discharged to home less frequently than younger patients (P < 0.05). Total and daily charges were 21-162% higher in THA patients with BMIs > or =50 kg/m than in THA patients with BMIs <50 kg/m (P < 0.045). CONCLUSION: All patients made functional gains during rehabilitation. However, the most costly and lengthy rehabilitation occurred in TKA patients > or =85 yrs and THA patients with BMI > or =50 kg/m.     

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.     

Severe penetrating head injury: a study of outcomes

OBJECTIVE: To determine and describe the demographics and functional outcomes of persons who require inpatient rehabilitation for severe penetrating head injury resulting from a gunshot wound to the head. DESIGN: Data were collected prospectively from the time of admission to acute care through discharge from inpatient rehabilitation. SETTING: Two sites: an urban, level I, acute care, trauma center and an inpatient rehabilitation hospital with a specialized brain injury unit. PARTICIPANTS: Twenty-seven persons with severe penetrating head injury. MAIN OUTCOME MEASURES: The FIM instrument, the Disability Rating Scale (DRS), and the length of stay (LOS). RESULTS: Demographic data showed our population to be similar to other groups of persons at high risk for violent injury. Eighty-five percent of the subjects were men with a mean age of 34 years. The majority were African American (93%), reflective of our general patient population. Average acute care LOS was 31 days and average rehabilitation LOS was 44 days. Average FIM gain was 40.2 and, on average, DRS scores improved 7.6 points from rehabilitation admission to discharge. All study participants made enough progress to be discharged to private residences. CONCLUSION: Although the mortality rate is high among patients with penetrating head injury, those who survive to receive inpatient rehabilitation can achieve functional improvement.     

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.
