Factors associated with patients' participation in rehabilitation services: a comparative injury analysis 12 months post-discharge

Purpose: To determine key characteristics or factors associated with rehabilitation participation during the first year following discharge for persons with either traumatic brain injury (TBI), spinal cord injury (SCI), intra-articular fracture (IAF), or burn injury (BURNS). Method: Medical records and longitudinal survey [telephone questionnaire] data were collected for persons in the four injury groups and analyzed using hierarchical logistic regression procedures for each domain of factors. Results: The only significant predictors with odds ratios greater than one were those for vocational rehabilitation participation. TBI patients lacking private insurance were 2.6 times more likely to participate in vocational rehabilitation; older SCI and TBI patients are about twice as likely to participate in vocational rehabilitation; and finally those with IAF or BURNS who are married at 12 months post discharge are 11.5 and 4.4 times respectively more likely to participate in vocational rehabilitation. Conclusion: Those lacking valuable socio-economic resources, such as private insurance (for TBI) and social support systems provided by marriage (for BURNS and IAF patients) are much more likely to be referred to vocational rehabilitation. This is true for older SCI and TBI patients as well. Lacking such resources, patients may be viewed by referral agents as less likely to benefit from in or outpatient rehabilitation.     

Spinal cord injury and co-occurring traumatic brain injury: assessment and incidence

Macciocchi S, Seel RT, Thompson N, Byams R, Bowman B. Spinal cord injury and co-occurring traumatic brain injury: assessment and incidence.

Objectives

To examine prospectively the incidence and severity of co-occurring traumatic brain injury (TBI) in persons with traumatic spinal cord injury (SCI) and to describe a TBI assessment process for SCI rehabilitation professionals.

Design

A prospective, cohort design to collect and analyze clinical variables relevant for diagnosing co-occurring TBI.

Setting

An urban, single-center National Institute of Disability and Rehabilitation Research Model Spinal Cord Injury System in the Southeastern United States.

Participants

People (N=198) who met inclusion criteria and provided consent within an 18-month recruitment window.

Interventions

Not applicable.

Main Outcome Measure

FIM cognitive scale.

Results

Based on participants' presence and duration of posttraumatic amnesia, initial Glasgow Coma Scale total score, and presence of cerebral lesion documented by neuroimaging, 60% of our traumatic SCI sample also sustained a TBI (n=118). Most co-occurring TBIs were mild (34%). Co-occurring mild complicated (10%), moderate (6%), and severe TBI (10%) were less common but still occurred in a significant percentage (26%) of persons with traumatic SCI. Persons with traumatic SCI who were injured in motor vehicle collisions and falls were more likely to sustain a co-occurring TBI. Cervical level traumatic SCI was associated with greater rates of TBI but not more severe injuries. Tree analyses established a practical algorithm for classifying TBI severity associated with traumatic SCI. Analysis of variance established criterion validity for the algorithm's TBI severity classifications.

Conclusions

Findings from our prospective study provide strong support that TBI is a common co-occurring injury with traumatic SCI. Incomplete acute care medical record documentation of TBI in the traumatic SCI population remains a considerable issue, and there is a significant need to educate emergency department and acute care personnel on the TBI clinical data needs of acute rehabilitation providers. A systematic algorithm for reviewing acute care medical records can yield valid estimates of TBI severity in the traumatic SCI population.

Delayed cervical spinal cord injury after high voltage electrical injury: a case report.

High voltage electrical injuries usually cause devastating consequences for patients, most of which result in permanent disability. Spinal cord injury (SCI) caused by high voltage electrical injury is uncommon in the literature. We present a 29-year-old male patient who was diagnosed as having delayed SCI after high voltage electrical injury. The patient developed muscle weakness in the lower extremities with the loss of pinprick sensation below the fifth cervical spinal segment, 2 days after the high voltage electrical injury. Magnetic resonance imaging of the brain, cervical and thoracic spine was normal. Nerve conduction and needle electromyography studies were normal, except for bilateral tibial and left median somatosensory-evoked potentials. The findings on initial examination and neurophysical investigation showed incomplete cervical SCI at the C5 level. He was able to walk with a pair of canes and bilateral ankle-foot orthosis at the end of the 2-month rehabilitation. Follow-up physical and electrophysiological examination of the patient 15 months after injury showed further improvement. The patient was able to walk with a pair of canes without orthoses. Electrophysiological studies are useful instruments in the diagnosis and follow-up of these patients. Early rehabilitation is essential to obtain a favorable outcome in patients with SCI caused by high voltage electrical injury.     

Spinal cord injury: a comprehensive review

Spinal cord injury (SCI) results in multiorgan system dysfunction. Previously, SCI portended reduced survival and diminished quality of life. However, with increasing awareness and advances in the management of complications from SCI, individuals are living longer and more satisfying lives. This article summarizes major interventions and advances in the management of patients who have SCI. Fundamental principles of SCI are reviewed by organ system and key points are highlighted.     

Life satisfaction following spinal cord and traumatic brain injury: a comparative study

The current study was designed to examine the predictive validity of several factors that are common to spinal cord injury (SCI) and traumatic brain injury (TBI) populations to overall life satisfaction. We examined several demographic and functional predictors (1) within each group separately and (2) using both groups while controlling for unique predictors within groups. Participants included 190 and 57 individuals with SCI and TBI, respectively. To minimize the influence of injury duration, we assessed life satisfaction at 1-year postinjury in both groups. Functional disability (Functional Impairment Measure [FIM]) was the only common predictor within groups. For the TBI group, marital status was also a significant predictor of life satisfaction. None of the other predictors examined was significant among the SCI group. After functional disability and marital status were controlled, overall life satisfaction did not differ between groups. Total explained variance in life satisfaction was low in both groups, 9% and 25% in the SCI and TBI groups, respectively. Future directions are discussed.     

Guidelines for routine respiratory care of patients with spinal cord injury. A clinical report

Pulmonary compromise is a leading cause of morbidity in patients with spinal cord injury (SCI). Because these patients have such complex and massive needs, routine respiratory care is not always given the priority it deserves in a rehabilitation program. Our institution established a committee to formulate guidelines for the routine respiratory care of patients in our interdisciplinary Acute Spinal Cord Injury Program. The guidelines consisted of evaluation, treatment, and teaching interventions. The purposes of the guidelines were to increase staff awareness of the need for routine, prophylactic respiratory care of patients with SCI; to be an effective teaching tool for staff, thus resulting in a reduction of respiratory complications; and also to be a teaching tool for patients and their families so that routine respiratory care could be continued in the home. After using the guidelines for over a year, we believe that the quality of the respiratory care we provide our patients with SCI has improved. The respiratory care is more comprehensive, consistent, and coordinated among disciplines.     

Spinal cord injury

Purpose : This article is an overview of the newer therapeutic interventions employed in the care of the spinal cord injured individual and the theoretical rationale supporting them. Issue : Spinal Cord Injury (SCI) care was, until recently, a maintenance type treatment, addressing systems mostly affected by complications of the original injury (e.g. bladder, skin, spasiticity). Conclusion : With the recent advances in the neuroscience field, more aggressive interventions geared at secondary injury prevention, neuronal regeneration and functional restoration are emerging.     

Spinal cord injury in partial Down syndrome

Spinal cord injury is well documented in Down syndrome, and is commonly associated with atlantoaxial instability and ligamentous laxity. A case of partial Down syndrome is presented in which a cervical spine injury resulted in an incomplete quadriplegia. Possible factors leading to increased risk of SCI in partial Down syndrome are ligamentous laxity, atlantoaxial subluxation or odontoid abnormalities, neck inflammatory changes, and age below eight years.     

Augmentative and alternative communication intervention in children with traumatic brain injury and spinal cord injury

Children and youth who sustain a traumatic brain injury (TBI) and/or spinal cord injury (SCI) may have temporary or permanent disabilities that affect their speech, language and communication abilities. Having a way to communicate can help reduce children's confusion and anxiety, as well as enable them to participate more actively in the rehabilitation process and thus, recover from their injuries. In addition, effective communication with family, care staff, peers, teachers and friends is essential to long-term recovery and positive outcomes for children with TBI and SCI as they are integrated back into their communities. This article describes how rehabilitation teams can use augmentative and alternative communication (AAC) and assistive technologies (AT) to support the communication of children recovering from TBI and SCI over time.

A comparison of independent living outcomes following traumatic brain injury and spinal cord injury

This study compares independent living outcomes in persons with traumatic brain injury (TBI) and spinal cord injury (SCI). Both injuries represent life-altering events that are known to have a negative impact on independent living and are predominantly experienced by members of the same demographic group. However, the types of resultant impairments and disabilities experienced by the two populations differ substantially. The TBI participants were recruited consecutively from Canada's largest tertiary care trauma centre and followed prospectively for four years. The SCI participants were recruited via a mailed survey to members of a provincial branch of the Canadian Paraplegic Association. Independent living outcomes were measured using DeJong and Hughes' (1982) classification system of productivity status, the Reintegration to Normal Living Index, and questions on assistance from environmental supports in the form of wheelchair use and paid/unpaid personal assistance. The TBI group was found to be significantly more productive, have higher levels of satisfaction with their current experience of community integration, and use fewer environmental supports than their SCI counterparts (P相似文献   

The effectiveness of different methods of defining traumatic brain injury in predicting postdischarge adjustment in a spinal cord injury population

Traumatic brain injury (TBI) can occur concomitantly with spinal cord injury (SCI). Much of the initial work in this area has focused on identifying coincidence rates and risk factors; less has focused on possible long-term implications of TBI when it occurs with SCI. In this study, SCI/TBI and neurologically matched SCI-only groups were formed on the basis of clinicians' ratings of neuropsychologic test scores. SCI/TBI and SCI-only groups were also formed using Halstead Category cutoff scores, presence/absence of loss of consciousness, and clinicians' ratings of severity of TBI. Dependent measures assessed an average of two years postinjury measured personal, social, and family adjustment of the individual with SCI and that of a significant other. Loss of consciousness and nonconsensus clinical ratings of presence/absence of TBI predicted postdischarge adjustment poorly. Severity ratings in the moderate to severe range, and Category cutoff scores did have some predictive value, with patients defined as impaired being more likely to report adjustment difficulties or being described as having adjustment difficulties by a significant other. The difficulty of making unequivocal diagnoses of TBI in this population is discussed and implications for future research delineated.     

Cardiovascular responses and postexercise hypotension after arm cycling exercise in subjects with spinal cord injury

OBJECTIVE: To examine postexercise hypotension and contributing factors in subjects with spinal cord injury (SCI). DESIGN: Prospective clinical research study. SETTING: Rehabilitation center. PARTICIPANTS: Subjects with chronic cervical-level (n=19) and thoracic-level (n=8) SCI. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Subjects underwent graded arm-cycling with electrocardiogram and oxygen uptake monitoring to exhaustion. Heart rates and blood pressures were measured before and after exercising. Injury to motor and sensory pathways was determined by American Spinal Injury Association grade, and to autonomic pathways by sympathetic skin responses (SSRs) (n=16). RESULTS: Resting blood pressures and heart rates were lower in cervical than thoracic SCI (mean arterial pressure [MAP]: cervical, 76.6+/-2 mmHg; thoracic, 93.5+/-3 mmHg; P<.001). Following exercise, heart rate responses were greater in thoracic than cervical SCI; MAP increased in thoracic SCI (8.4+/-5 mmHg) and markedly decreased in cervical SCI (-9.3+/-2 mmHg) (P<.001). No subject had significant electrocardiographic abnormalities at rest or during exercise. There were correlations between SSR and heart rate and blood pressure responses to exercise; the correlation between the SSR and blood pressure response was due to an interaction between the heart rate and blood pressure responses. CONCLUSIONS: Abnormal cardiovascular responses to exercise and transient postexercise hypotension were common in cervical, but not thoracic SCI. This may be partly related to loss of descending sympathetic nervous control of the heart and vasculature following high SCI.     

Neurologic recovery after traumatic spinal cord injury: data from the Model Spinal Cord Injury Systems

OBJECTIVE: To present data on neurologic recovery gathered by the Model Spinal Cord Injury (SCI) Systems over a 10-year period. DESIGN: Case series. SETTING: Twenty-one Model SCI Systems. PATIENTS: A total of 3,585 individuals with traumatic SCI admitted between January 1, 1988 and December 31, 1997. MAIN OUTCOME MEASURES: Neurologic impairment category; Frankel grade; American Spinal Injury Association (ASIA) Impairment Scale (AIS) grade; motor score. RESULTS: SCI caused by violence is more likely than SCI from nonviolent etiologies to result in a complete injury. Changes in severity of injury were similar using the older Frankel scale and the newer ASIA Impairment Scale. Individuals who were motor-complete with extended zones of sensory preservation but without sacral sparing were less likely to convert to motor-incomplete status than those with sacral sparing (13.3% vs 53.6%; p < .001). Motor score improvements at 1 year were related to severity of injury, with greater increases for better AIS grades except grade D, because of ceiling effects. Individuals with AIS grade B injuries have a mixed prognosis. CONCLUSION: Neurologic recovery after SCI is influenced by etiology and severity of injury. Multicenter studies on prognostic features such as preserved pin sensation in grade B injuries may identify subgroups with similar recovery patterns. Identification of such groups would facilitate clinical trials for neurologic recovery in acute SCI.     

Economics of managed care in spinal cord injury

OBJECTIVE: To determine and describe trends in economic variables related to the care of individuals with spinal cord injury (SCI) and significant changes in these trends coincident with major developments in medical care cost control. DATA SOURCES: Data from the National Spinal Cord Injury Statistical Center (NSCISC) database were used to review the economic trends in SCI management from 1973 to 1998 and their relation to managed care and other health care cost-containment measures. A panel of SCI health care specialists was interviewed to determine the appropriate data variables to be reviewed. The Shepherd Center Care Health Management Program, Atlanta, GA, is presented as an example of a fiscally successful managed care program for patients with SCI. DATA EXTRACTION: Data from the NSCISC database for the years studied were extracted and converted to a form suitable for analysis by means of the statistical software SAS. DATA SYNTHESIS: Statistical techniques included multiple regression analysis, logistic regression analysis, and model selection methods. CONCLUSIONS: Trends in economic variables, in the care of individuals with SCI show changes coincident with the introduction of Diagnostic Related Groups (DRGs) and managed care as models for provider reimbursement. Significant changes occurred in acute care charges, rehabilitation charges, length of stay, rehospitalization 1 year postinjury, time from injury to admission to a Model System, and discharges to a nursing home.     

Assessment of autonomic dysfunction following spinal cord injury: rationale for additions to International Standards for Neurological Assessment

We present a preliminary report of the discussion of the joint committee of the American Spinal Injury Association (ASIA) and the International Spinal Cord Society concerning the development of assessment criteria for general autonomic function testing following spinal cord injury (SCI). Elements of this report were presented at the 2005 annual meeting of the ASIA. To improve the evaluation of neurological function in individuals with SCI and therefore better assess the effects of therapeutic interventions in the future, we are proposing a comprehensive set of definitions of general autonomic nervous system dysfunction following SCI that should be assessed by clinicians. Presently the committee recommends the recognition and assessment of the following conditions: neurogenic shock, cardiac dysrhythmias, orthostatic hypotension, autonomic dysreflexia, temperature dysregulation, and hyperhidrosis.     

Spinal cord injury and aging: challenges and recommendations for future research

Population aging, caused by reductions in fertility and increasing longevity, varies by country and is anticipated to continue and to reach global proportions during the 21st century. Although the effects of population aging have been well documented for decades, the impact of aging on people with spinal cord injury (SCI) has not received similar attention. It is reasonable to expect that population aging features such as the increasing mean age of the population, share of the population in the oldest age groups, and life expectancy would be reflected in SCI population demographics. Although the mean age and share of the SCI population older than 65 yrs are increasing, data from the National Spinal Cord Injury Statistical Center suggest that life expectancy increases in the SCI population have not kept the same pace as those without SCI in the last 15 yrs. The reasons for this disparity are likely multifactorial and include the changing demographics of the SCI population with more older people being injured; susceptibility of people with SCI to numerous medical conditions that impart a health hazard; risky behaviors leading to a disproportionate percentage of deaths as a result of preventable causes, including septicemia; changes in the delivery of health services during the first year after injury when the greatest resources are available; and other unknown factors. The purposes of this paper are (1) to define and differentiate general population aging and aging in people with SCI, (2) to briefly present the state of the science on health conditions in those aging with SCI, and finally, (3) to present recommendations for future research in the area of aging with SCI.     

The incidence of neurogenic shock in patients with isolated spinal cord injury in the emergency department

BACKGROUND: Spinal cord injury (SCI) is recognised to cause hypotension and bradycardia (neurogenic shock). Previous studies have shown that the incidence of this in the emergency department (ED) may be low. However these studies are relatively small and have included a mix of blunt and penetrating injuries with measurements taken over different time frames. The aim was to use a large database to determine the incidence of neurogenic shock in patients with isolated spinal cord injuries. METHODS: The Trauma Audit and Research Network (TARN) collects data on patients attending participating hospitals in England and Wales. The database between 1989 and 2003 was searched for patients aged over 16 who had sustained an isolated spinal cord injury. The heart rate (HR) and systolic blood pressure (SBP) on arrival at the ED were determined as was the number and percentage of patients who had both a SBP<100mm Hg and a HR<80 beats per minute (BPM) (the classic appearance of neurogenic shock). RESULTS: Four hundred and ninety patients had sustained an isolated spinal cord injury (SCI) with no other injury with an abbreviated injury scale (AIS) of greater than 2. The incidence of neurogenic shock in cervical cord injuries was 19.3% (95% CI 14.8-23.7%). The incidence in thoracic and lumbar cord injuries was 7% (3-11.1%) and 3% (0-8.85%). CONCLUSIONS: Fewer than 20% of patients with a cervical cord injury have the classical appearance of neurogenic shock when they arrive in the emergency department. It is uncommon in patients with lower cord injuries. The heart rate and blood pressure changes in patients with a SCI may develop over time and we hypothesise that patients arrive in the ED before neurogenic shock has become manifest.     

A functional classification of respiratory compromise in spinal cord injury

Spinal cord injury (SCI) patients have unique care needs, particularly related to the respiratory system. Respiratory problems now comprise a major cause of death in the acute and chronic phases of SCI, especially among quadriplegics. Previous literature has analyzed respiratory muscle dysfunction in SCI according to neurologic levels of injury (Alvarez, Peterson & Lunsford, 1981; McMichan, Michel & Westbrook, 1980). In general, the higher the level of injury, the greater the respiratory compromise and need for ventilatory assistance. Although level of injury is significant, it cannot be used as the sole determinant of respiratory compromise. For example, a 25 year old C4 quadriplegic with an intact diaphragm might have less respiratory impairment than a 60 year old C6 quadriplegic with CHF and a history of COPD. A new classification of SCI patients according to amount of respiratory compromise was developed by our team at the Spinal Cord Injury Unit at the Palo Alto VA Medical Center. The patient is scored in three categories: 1) level of injury; 2) completeness of injury; and 3) associating factors, i.e. age, preinjury chronic lung disease. The purpose of this grouping is to better predict the amount of ventilatory impairment in SCI patients. Used during the initial assessment, patients at high risk for impairment could be determined and optimal respiratory care initiated. This classification can also be used as a clinical nursing tool. Using this scoring system, the nurse could anticipate the patient's respiratory needs, i.e. suctioning, chest physiotherapy, oxygen, hydration, nutritional support and teaching of patient and family in order to comprehensively plan and implement care.(ABSTRACT TRUNCATED AT 250 WORDS)
