Aging with Spinal Cord Injury

"I am just trying to live a life!" -a qualitative study of the lived experience of pressure ulcers in people with spinal cord injuries

BACKGROUND

Pressure ulcers (PUs) are frequently reported in people with spinal cord injuries (SCI). Wound management in people with SCI involves relieving pressure on the affected area by means of immobilisation and bed rest. The healing time of a PU can vary, but often takes several months or even years, causing people to stay in bed for prolonged periods of time.

OBJECTIVE

This study aims to explore the perspectives and lived experiences of people with SCI who are affected by PUs.

DESIGN

and method: This study is a qualitative explorative study that employs individual semi-structured in-depth interviews to obtain the narratives of people with SCI and a pressure ulcer. We used a phenomenological-hermeneutic approach that was inspired by Ricoeur's theory of interpretation. The analysis was performed in three levels: Naïve reading, structural analysis and critical interpretation and discussion.

PARTICIPANTS

and setting: Ten people with SCI who were being treated in the Danish healthcare system for their PU participated in this study: six participants had experienced a complete traumatic SCI, three had an incomplete traumatic SCI, and one had a non-traumatic complete SCI. The study included nine men and one woman, aged 49-81 years (mean 64). Nine had a PU in the seating area, while one had the ulcer on the leg.

RESULTS

The analysis revealed three themes: 1. Struggling to balance prevention with an active, meaningful life, 2. Challenges and consequences of pressure relief protocols and bed rest, 3. Experiencing prolonged and incoherent treatment with varying levels of staff engagement and competencies.

CONCLUSIONS

People with SCI and a PU have difficulty balancing their active, redefined lives when subjected to a strict pressure relief protocol. The consequences of immobility caused by pressure relief include reduced social and community participation and decreased quality of life. PU treatment is experienced as incoherent and unnecessarily lengthy, leading to a deterioration in the wounds. Improving PU treatment for people with SCI is of utmost importance and has the potential to benefit not only the people with SCI but also the healthcare system and the economy.

Aging with spinal cord injury: A narrative review of consequences and challenges

Given the increase in life expectancy, aging with a pre-existing spinal cord injury (SCI) is becoming more common. This condition is challenging as compromised health status and functional independence can worsen. We aimed to provide an updated overview of the consequences of aging with SCI, highlighting the main challenges facing this population in a narrative review of the current literature we retrieved from the PubMed database from 2000 to 2022 on any aspect related to aging in persons with SCI. Here we address adverse circumstances that increase disability and hinder an active lifestyle, such as progressive physical deterioration, secondary health conditions, limitations in personal activity, changes in family and social support structures, aging of caregivers, and depletion of economic resources. Favorable changes are also observed, including psychosocial adjustments that improve quality of life. Additionally, various interventions are discussed to promote well-being, health, and social participation. Due to the relevance of this issue, people with SCI and all those who take care of them must have up-to-date information to carry out the necessary measures to promote healthy aging in a more inclusive social environment.

The Role of Environmental Factors on Health Conditions, General Health and Quality of Life in Persons with Spinal Cord Injuries in South Africa

OBJECTIVE

The objective was to describe the individual items of the environmental factors and to investigate the relationship between the environmental factors to health conditions, general health and quality of life in people with SCI in South Africa.

METHODS

Two hundred persons with SCI participated in a cross-sectional survey design. This study formed part of the International Spinal Cord Injury (InSCI) Community Survey. Four major domains, environmental factors, health conditions, general health and quality of life of the survey questionnaire responses, were used for the analysis. Regression models were used to determine the association between the independent variable, which consisted of the specific environmental factors items, and the dependent variables comprising health conditions, general health and quality of life.

RESULTS

The commonly reported environmental barriers were public access, lack of short- and long-distance transport and finances. Environmental factors such as public access (p < 0.001), short- (p < 0.001) and long-distance transport (p = 0.001), and friends' (p = 0.003) and colleagues' (p < 0.001) attitudes and communication (p = 0.042) were significantly associated with the presence of secondary health conditions. Finances (p = 0.026), family attitudes (p = 0.037) and communication (p = 0.039) had a significant association with worsened mental health. Services (p = 0.022) and communication (p = 0.042) were also significantly associated with decreased general health.

CONCLUSION

The results provide insight into modifiable environmental factors policymakers need to consider or adapt to improve the lives of people with SCI in South Africa with respect to health (secondary health conditions), as well as general and mental health.

Feasibility study of high-intensity interval training to reduce cardiometabolic disease risks in individuals with acute spinal cord injury

INTRODUCTION

Individuals ageing with spinal cord injury (SCI) experience an accelerated trajectory of diseases and disorders, such as cardiovascular disease and diabetes, that resemble those experienced with ageing alone. Currently, an evidence-based approach toward managing this problem does not exist and therefore the purpose of this study is to determine the feasibility of conducting a high-intensity exercise intervention in individuals with acute (<6 months postinjury) SCI to improve cardiometabolic health.

METHODS AND ANALYSIS

We will conduct a single-centre, two parallel-arm, randomised feasibility study of a high-intensity interval training (HIIT) intervention in individuals with acute SCI. We will enrol 40 individuals (20 intervention, 20 control) with acute SCI attending inpatient rehabilitation at Salisbury District Hospital. Participants will be randomly allocated to the intervention group (HIIT) or control group for 18 weeks. Both groups will participate in standard care throughout the duration of the study. The HIIT group only will also perform supervised HIIT exercise on an arm cycle ergometer three times per week. Over the course of the intervention, most participants will be discharged from the hospital, and at this time, an arm cycle ergometer will be installed in their home and the intervention will transition into outpatient care. We will assess cardiorespiratory fitness, glycaemic control, lipid profile and body habitus as well as qualitative assessments of acceptability at weeks 0, 9 and 18 with the primary outcome being the feasibility of a full Randomised Controlled Trial (RCT).

ETHICS AND DISSEMINATION

This study will inform a longer-term, definitive, multicentre RCT to establish the impact of this exercise intervention in maintaining the cardiometabolic health of patients during the acute phase following SCI. Results will be disseminated in different formats including peer-reviewed journal articles, conference presentations and internet media, to a wide audience including clinicians, researchers and individuals with SCI.

Systemic inflammation after spinal cord injury: A review of biological evidence, related health risks, and potential therapies

Individuals with chronic traumatic spinal cord injury (SCI) develop progressive multi-system health problems that result in clinical illness and disability. Systemic inflammation is associated with many of the common medical complications and acquired diseases that accompany chronic SCI, suggesting that it contributes to a number of comorbid pathological conditions. However, many of the mechanisms that promote persistent systemic inflammation and its consequences remain ill-defined. This review describes the significant biological factors that contribute to systemic inflammation, major organ systems affected, health risks, and the potential treatment strategies. We aim to highlight the need for a better understanding of inflammatory processes, and to establish appropriate strategies to address inflammation in SCI.

Endocrinological and inflammatory markers in individuals with spinal cord injury: A systematic review and meta-analysis

Spinal cord injury (SCI) can lead to dramatic physiological changes which can be a factor in developing secondary health conditions and might be reflected in biomarker changes in this elevated risk group. We focused specifically on the endocrine and inflammation profile differences between SCI and able-bodied individuals (ABI). Our aim was to determine the differences in inflammatory markers and endocrine profiles between SCI and ABI. We systematically searched 4 electronic databases for relevant studies. Human observational (cross-sectional, cohort, case-control) studies that compared biomarkers of interest between SCI and ABI population were included. Weighted mean difference between SCI and ABI was calculated using random-effects models. Heterogeneity was computed using I² statistic and chi-squared test. Study quality was evaluated through the Newcastle-Ottawa Scale. The search strategy yielded a total of 2,603 studies from which 256 articles were selected for full-text assessment. Sixty-two studies were included in the meta-analysis. SCI individuals had higher levels of pro-inflammatory C-reactive protein and IL-6 than ABI. Creatinine and 25-hydroxyvitamin D₃ levels were lower in SCI than ABI. Total testosterone levels and IGF-1 were also found to be lower, while cortisol and leptin levels were higher in SCI when compared to ABI. Accordingly, meta-regression, subgroup analysis, and leave-one-out analysis were performed, however, they were only able to partially explain the high levels of heterogeneity. Individuals with SCI show higher levels of inflammatory markers and present significant endocrinological changes when compared to ABI. Moreover, higher incidence of obesity, diabetes, osteoporosis, and hypogonadism in SCI individuals, together with decreased creatinine levels reflect some of the readily measurable aspects of the phenotype changes in the SCI group. These findings need to be considered in anticipating medically related complications and personalizing SCI medical care.

Staying active after rehab: Physical activity perspectives with a spinal cord injury beyond functional gains

Lifestyle physical activity following spinal cord injury (SCI) is critical for functional independence, mental wellness, and social participation, yet nearly 50% of individuals with SCI report no regular exercise. The objective of this study was to better understand factors leading to this participation gap by capturing the physical activity perspectives of individuals living with SCI. We completed small group interviews with nine individuals living with SCI across the United States. Iterative thematic analysis systematically revealed meaningful core concepts related to physical activity engagement with SCI. Emergent themes revealed challenges to lifestyle physical activity behavior including gaps in physical activity education, isolation during psychological adjustment, and knowledge limitations in community exercise settings. A secondary theme related to the COVID-19 pandemic emerged, highlighting additional environmental constraints affecting participation. Our findings suggest that most physical activity education is delivered during inpatient rehabilitation and is related to physical function. Lifetime physical activity strategies are achieved through self-education and peer networking. Personal motivators for physical activity include secondary condition prevention, while social and emotional barriers prevent regular adherence. These findings can inform the development and delivery of physical activity programs to maximize physical activity engagement in individuals living with chronic SCI.

Hybrid Functional Electrical Stimulation improves anaerobic threshold in first three years following spinal cord injury

The purpose of the present investigation was to assess the effects of whole-body exercise on anaerobic threshold in individuals with spinal cord injury (SCI). Maximal oxygen uptake (VO2max) and oxygen uptake at anaerobic threshold (AT) were measured before and after 6 months of hybrid functional electrical stimulation row training in 47 participants with SCI aged 19-63, neurological levels of injury C4-L1, American Spinal Injury Association Impairment Scale grades A-D, and time since injury at enrollment from 3 months to 40 years. Changes in VO2max differed with time since injury, with greater increases earlier post injury. The early chronic group (<3 years since injury; n=31) increased VO2max from 1.65 ± 0.54 L/min at baseline to 1.83 ± 0.66 L/min at 6 months (p<0.05), while the late chronic group (>3 years since injury; n=16) did not change (1.42 ± 0.44 at baseline to 1.47 ± 0.41 L/min at 6 months, p=0.36). Consistent with VO2max changes, AT increased in the early chronic group (1.03 ± 0.31 to 1.20 ± 0.40 L/min, p<0.05) and did not change in the late chronic group (0.99 ± 0.31 to 0.99 ± 0.26 L/min, p=0.92). Cumulative duration of exercise training was positively correlated to change in VO2max (r=0.475, p<0.05) but not to change in AT. Hybrid functional electrical stimulation row training is effective for increasing aerobic capacity and anaerobic threshold in individuals with spinal cord injury; however, these fitness benefits are only significant in individuals initiating the exercise intervention within three years of injury.

A mixed-methods study exploring and comparing the experiences of people who sustained a spinal cord injury earlier versus later in life

STUDY DESIGN

Mixed-methods.

OBJECTIVES

(1) To explore psychosocial and quality of life outcomes between those injured early versus later in life, and (2) to explore their post-injury experiences.

SETTING

GF Strong Rehabilitation Centre, Vancouver, Canada.

METHODS

For this community-based study, we recruited individuals with SCI (>55 years of age) who were either injured between the ages of 15-30 (n = 15) or after the age of 50 (n = 15). We collected quantitative data about participants' sociodemographics and participants completed standardised questionnaires assessing personal factors, environmental factors, life habits, and quality of life. An independent samples t test was performed for continuous variables and the Chi-square test was conducted for the categorical variables. Qualitative data were collected via semi-structured interviews. Thematic content analysis was performed on the interview transcripts.

RESULTS

We found no statistically significant differences between the two groups on any of the psychosocial outcomes. However, those injured later in life were significantly more likely to be female, have a higher income, and live in residential care. We identified three main qualitative themes that were consistent across the two groups: 'dealing with health and changes in occupation', 'enacting interdependence', and 'living in the community'. Some sub-themes varied between groups.

CONCLUSIONS

To facilitate better rehabilitation, clinicians need to be aware of disparities among people with SCI relating to age of injury. Across age cohorts, it is important to increase independence, provide greater support when entering or returning to the workforce, and reduce societal stigma.

Identification of Mood and Body Mass Index as Modifiable Factors for Health Improvement in Spinal Cord Injury

•

Higher body mass index (BMI) is associated with lower positive affect in individuals with spinal cord injury (SCI).

•

Women with SCI are at higher risk of developing increased negative affect than men.

•

Older individuals with SCI have a greater chance of developing higher BMI.

•

Premorbid personality traits with respect to mood and BMI are essential to interpret the association of BMI and positive affect.

Community dwelling life- and health issues among persons living with chronic spinal cord injury in North Macedonia

STUDY DESIGN

Cross-sectional study.

OBJECTIVES

The purpose was to reveal late health consequences and life issues after a traumatic spinal cord injury (tSCI) in North Macedonia (NM).

SETTING

Community dwelling adults with tSCI in NM.

METHODS

Persons that sustained tSCI in 1999-2005 were selected, physical examined and a questionnaire was administered. Descriptive statistics were conducted.

RESULTS

From 203 eligible persons, 40 agreed to participate. Mean (range) age at time of injury was 36 (27-75) years and time since injury ranged 9-20 years. Around seventy percent reported current health problems, of which pain and spasm (>60%) were most prevalent, followed by urinary tract infections and pressure injuries. About 30% had never been to a medical specialist and ≈70% had only once been to physiotherapy after discharge from the primary inpatient period. Only one participant had a fully adjusted home for a person with a disability. Those with most severe tSCI (American Spinal Injury Association Impairment Scale (AIS) A, B, and C) seldom left their homes. About 50% were retired and/or unemployed, 50% were working.

CONCLUSION

This is the first study describing community-dwelling persons with a tSCI in NM. Our study revealed that persons with tSCI reported health issues mostly related to pain, spasms, urinary tract infections and pressure injuries. They lacked follow-ups, experienced physical barriers and poor inclusion in the society, and lacked financial support. Therefore, they were often socially isolated and fully dependent on their families. NM is in need of structured rehabilitation programs and better adaption for persons with reduced mobility.

Cardiometabolic risks and atherosclerotic disease in ApoE knockout mice: Effect of spinal cord injury and Salsalate anti-inflammatory pharmacotherapy

OBJECTIVE

To test in mice with a double mutation of the ApoE gene (ApoE-/-) whether spinal cord injury (SCI) hastens the native trajectory of, and established component risks for, atherosclerotic disease (AD), and whether Salsalate anti-inflammatory pharmacotherapy attenuates the impact of SCI.

METHODS

ApoE-/- mice were anesthetized and underwent a T9 laminectomy. Exposed spinal cords were given a contusion injury (70 k-dynes). Sham animals underwent all surgical procedures, excluding injury. Injured animals were randomized to 2 groups: SCI or SCI+Salsalate [120 mg/Kg/day i.p.]. Mice were serially sacrificed at 20-, 24-, and 28-weeks post-SCI, and body mass was recorded. At sacrifice, heart and aorta were harvested intact, fixed in 10% buffered formalin, cleaned and cut longitudinally for en face preparation. The aortic tree was stained with oil-red-O (ORO). AD lesion histomorphometry was calculated from the proportional area of ORO. Plasma total cholesterol, triglycerides and proatherogenic inflammatory cytokines (PAIC's) were analyzed.

RESULTS

AD lesion in the aortic arch progressively increased in ApoE-/-, significant at 24- and 28-weeks. AD in SCI is significantly greater at 24- and 28-weeks compared to time-controlled ApoE-/-. Salsalate treatment attenuates the SCI-induced increase at these time points. Body mass in all SCI groups are significantly reduced compared to time-controlled ApoE-/-. Cholesterol and triglycerides are significantly higher with SCI by 24- and 28-weeks, compared to ApoE-/-, and Salsalate reduces the SCI-induced effect on cholesterol. PAIC's interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor α (TNFα), monocyte chemoattractant protein-1 (MCP-1), and chemokine (C-C motif) ligand 5 (CCL-5) are significantly greater with SCI compared to ApoE-/- at varying timepoints. Salsalate confers a marginal reducing effect on PAIC's by 28-weeks compared to SCI. Regression models determine that each PAIC is a significant and positive predictor of lesion. (p's <0.05).

CONCLUSIONS

SCI accelerates aortic AD and associated risk factors, and anti-inflammatory treatment may attenuate the impact of SCI on AD outcomes. PAIC's IL-1β, IL-6, TNFα, MCP-1, and CCL-5 may be effective predictors of AD.

"Earth angels" and parking spots: qualitative perspectives on healthy aging with spinal cord injury

PURPOSE

People aging with spinal cord injury (SCI) can experience the premature onset of comorbid conditions, as well as the development and progression of secondary health conditions. The aim of this study was to understand the subjective experiences of persons aging with SCI in relation to their surrounding social and physical environments, including the impact of barriers and facilitators.Material/Methods: Eleven individuals who had an SCI for more than ten years and were 45 years or older participated in a semi-structured phone interview about their experiences with healthy aging, social participation, social supports, and community barriers.

RESULTS

Four main themes emerged in the qualitative data that captured the subjective experience of aging with SCI. These were: (1) Maintaining Physical Independence; (2) Importance of Resources and Special Equipment; (3) Planning Ahead; and (4) Finding Ways to Adapt.

CONCLUSIONS

The findings from this study highlight the importance of looking beyond individual factors to consider the social and environmental factors that support continued independence and participation in society as people living with long term SCI experience their aging process. Qualitative research that delves further into the dynamics behind this process is needed to fully anticipate the needs of this growing population.IMPLICATIONS FOR REHABILITATIONPeople aging with spinal cord injury (SCI) who are engaged in their social and physical environments have become increasingly adaptive when faced with accelerating and secondary comorbidities.Programs and facilities should ensure universal access to prevention and self-management programs that target physical activity and health habits when considered in the context of a patient's socio-environmental constraints and resources.Clinical healthcare providers need to engage with their patients to develop an early intervention approach to preserve functional capacity while navigating potential future health problems.Clinicians should act as advocates for ongoing policy changes that help promote an environment more inclusive towards people aging with SCI.

Development and implementation of a community-based research network

Introduction:

People aging with long-term physical disabilities (PAwLTPD), meaning individuals with onset of disability from birth through midlife, often require long-term support services (LTSS) to remain independence. The LTSS system is fragmented into aging and disability organizations with little communication between them. In addition, there are currently no evidence-based LTSS-type programs listed on the Administration for Community Living website that have been demonstrated to be effective for PAwLTPD. Because of these gaps, we have developed a community-based research network (CBRN), drawing on the practice-based research network model (PBRN), to bring together aging and disability organizations to address the lack of evidence-based programs for PAwLTPD.

Materials and Methods:

Community-based organizations serving PAwLTPD across the state of Missouri were recruited to join the CBRN. A formative process evaluation of the network was conducted after a year to evaluate the effectiveness of the network.

Results:

Nine community-based organizations across the state of Missouri joined the CBRN. CBRN members include three centers for independent living (CILs), three area agencies on aging (AAAs), one CIL/AAA hybrid, one non-CIL disability organization, and one non-AAA aging organization. To date, we have held seven meetings, provided educational opportunities for CBRN members, and launched an inaugural research study within the CBRN. Formative evaluation data indicate that CBRN members feel that participation in the CBRN is beneficial.

Conclusion:

The PBRN model appears to be a feasible framework for use with community-based organizations to facilitate communication between agencies and to support research aimed at addressing the needs of PAwLTPD.

Clinical features of electric powered indoor/outdoor wheelchair users with spinal cord injuries: A cross-sectional study

This article aims to describe the characteristics of those with a primary diagnosis of spinal cord injury (SCI) attending a specialist wheelchair service providing electric powered indoor/outdoor chairs (EPIOCs). This cross-sectional study, with retrospective review of electronic and case note records, explores the complexities of additional clinical features associated with SCI and disability influencing prescription. Data were extracted under three themes; demographics, diagnostic/clinical information and wheelchair factors. There were 57 participants (35 men, 22 women) (mean age 53.51 ± 11.93, range 29-79 years) comprising 20 with paraplegia, 34 with tetraplegia and 3 with undocumented level. Paraplegics were significantly older than tetraplegics (p < 0.05). Thirty users had a complete SCI (mean age 49.87 ± 12.27 years) and 27 had another SCI lesion (mean age 57.56 ± 10.32 years). Those with a complete SCI were significantly younger than the rest (p < 0.02). Only 10 (9 tetraplegic) had SCI as the sole diagnosis. Twenty (15 tetraplegic) had one additional clinical feature, 14 had 2-3 (6 tetraplegic) and 13 (4 tetraplegic) had 4 or more. Ten users required specialised seating, 22 needed tilt-in-space EPIOCs while six required complex controls. The range and complexity of wheelchair and seating needs benefitted from a holistic assessment and prescription by a specialist multidisciplinary team.

Comprehensive Proteomic Profiling of Pressure Ulcers in Patients with Spinal Cord Injury Identifies a Specific Protein Pattern of Pathology

Objective: Severe pressure ulcers (PUs) do not respond to conservative wound therapy and need surgical repair. To better understand the pathogenesis and to advance on new therapeutic options, we focused on the proteomic analysis of PU, which offers substantial opportunities to identify significant changes in protein abundance during the course of PU formation in an unbiased manner. Approach: To better define the protein pattern of this pathology, we performed a proteomic approach in which we compare severe PU tissue from spinal cord injury (SCI) patients with control tissue from the same patients. Results: We found 76 proteins with difference in abundance. Of these, 10 proteins were verified as proteins that define the pathology: antithrombin-III, alpha-1-antitrypsin, kininogen-1, alpha-2-macroglobulin, fibronectin, apolipoprotein A-I, collagen alpha-1 (XII) chain, haptoglobin, apolipoprotein B-100, and complement factor B. Innovation: This is the first study to analyze differential abundance protein of PU tissue from SCI patients using high-throughput protein identification and quantification by tandem mass tags followed by liquid chromatography tandem mass spectrometry. Conclusion: Differential abundance proteins are mainly involved in tissue regeneration. These proteins might be considered as future therapeutic options to enhance the physiological response and permit cellular repair of damaged tissue.

Engaging in the prevention of pressure injuries in spinal cord injury: A qualitative study of community-dwelling individuals' different styles of prevention in Switzerland

Context: Spinal cord injury (SCI) is a complex chronic condition with multiple self-management requirements and a high prevalence of complications. Pressure injuries (PIs) are among the most common ones and represent a frequent reason for re-hospitalization. This study aimed to identify styles of prevention that individuals with SCI adopt to deal with the risk of developing PIs.Design: Qualitative explorative interview study. Data was collected through semi-structured interviews, which were transcribed verbatim and analyzed following the principles of thematic analysis.Setting: Switzerland.Participants: The participants were a purposive sample of community-dwelling Swiss residents with SCI for at least five years.Interventions: Not applicable.Outcome measures: Not applicable.Results: Although all participants (N = 20) showed at least a basic knowledge of prevention of PIs by describing some preventive measures, they had different prevention styles characterized by different behavioral patterns (i.e. complying with all recommended measures, performing only a selection of them or delegating them to others) and different beliefs and attitudes towards prevention.Conclusion: By identifying the style of prevention of an individual, it is possible to develop tailored interventions that have an impact on the factors which seem to play a role in determining the adoption of preventive behaviors (i.e. perceived susceptibility to PIs, attitudes towards prevention, and self-efficacy). Such interventions would constitute a concrete effort to support individuals with SCI during their self-management. Besides alleviating a frequent and disabling medical complication and contributing to an enhanced quality of life, these interventions might also help decrease healthcare costs.

Diagnosis and Management of Osteomyelitis Associated With Stage 4 Pressure Ulcers: Report of a Query to the Emerging Infections Network of the Infectious Diseases Society of America

Background

Few studies exist to guide the management of patients with stage 4 pressure ulcers with possible underlying osteomyelitis. We hypothesized that infectious disease (ID) physicians would vary widely in their approach to such patients.

Methods

The Emerging Infections Network distributed a 10-question electronic survey in 2018 to 1332 adult ID physicians in different practice settings to determine their approach to such patients.

Results

Of the 558 respondents (response rate: 42%), 17% had managed no such patient in the past year. Of the remaining 464 respondents, 60% usually felt confident in diagnosing osteomyelitis; the strongest clinical indicator of osteomyelitis reported was palpable or visible bone at the ulcer base. Approaches to diagnosing osteomyelitis in patients with visible and palpable bone varied: 41% of respondents would assume osteomyelitis, 27% would attempt pressure off-loading first, and 22% would perform diagnostic testing immediately. Preferred tests for osteomyelitis were bone biopsy (for culture and histopathology) and magnetic resonance imaging. Respondents differed widely on favored route(s) (intravenous, oral, or both) and duration of antimicrobial therapy but would treat longer in the absence, vs presence, of full surgical debridement (P < .001). Overall, 62% of respondents opined that osteomyelitis under stage 4 pressure ulcers is usually or almost always treated excessively, and most (59%) suggested multiple topics for future research.

Conclusions

Regarding osteomyelitis underlying stage 4 pressure ulcers, ID physicians reported widely divergent diagnostic and treatment approaches. Most of the reported practice is not supported by the available evidence, which is quite limited and of low quality.

Comprehensive Care for Persons with Spinal Cord Injury

Spinal cord injury results in multiple secondary comorbidities, which vary based on injury severity and other characteristics. Persons with spinal cord injury are at lifelong risk for many complications, most of which are at least partially preventable with proper medical care. The Veterans Health Administration Spinal Cord Injury and Disorders (SCI&D) System of Care offers these evaluations to all persons in their registries. Annual evaluations are performed at any of the 24 SCI&D Veterans Administration Centers nationwide. This allows veterans to receive the care from an interdisciplinary team that specializes in the care of veterans with spinal cord injury.

Health Service Utilization and State Costs Among Adults Aging With Early-Acquired Physical Disabilities in Medicaid Managed Care

Objective: We evaluated the impact of Medicaid managed care (MMC) on health service use and state costs among adults with early-acquired physical disabilities. Method: Using claims data, we tracked utilization of the emergency department (ED), inpatient admissions, outpatient physician visits, and state expenditures on enrollees who transitioned to MMC (n = 881). The inverse propensity score weight and a difference-in-differences regression model were used to estimate the impact of MMC using their counterparts who remained in fee-for-service (n = 1,552) as the comparison group. Results: MMC reduced ED use by 3.2% points/month (p < .001). Relative to younger enrollees (age ⩽45 years), MMC reduced inpatient admissions of older enrollees (age ⩾46 years) by 3.3% points/month (p < .001), and state expenditures by US$839/month (p < .01). Discussion: MMC could reduce the hospital service use of and state spending on enrollees with early-acquired physical disabilities. This impact may vary depending on the enrollees' age.

Participation restriction and assistance needs in people with spinal cord injuries of more than 40 year duration

Study design

Prospective observational.

Objectives

Examine changes in participation restriction and assistance needs in a sample of people with long-standing spinal cord injuries (SCIs).

Setting

Two British spinal centres.

Methods

The sample consisted of British ageing with SCI study participants who were seen at baseline (1990 or 1993) and in the final follow-up (2010). Outcome measures were the Craig Handicap Assessment and Reporting Technique-Short Form (CHART-SF) and interview questions about assistance needs.

Results

Eighty-five Ageing study participants took part in 2010; their mean age was 67.65 years and the mean time since injury was 46.26 years. The mean CHART-SF physical independence subscore decreased from 97.44 in 1990 to 91.26 in 2010, mobility from 95.58 to 82.10, occupation from 86.82 to 64.49 and social integration from 96.29 to 88.68 (all p < 0.05). Increasing assistance needs were reported by 10.1% of participants in 1990, by 36.6% in 2010 (p < 0.05) and by 62.4% over the entire 20-year study period. Persons requiring more assistance were older and injured longer, had a more severe SCI and lower self-reported quality of life and life satisfaction (p < 0.05). In the multivariate logistic regression, the strongest predictor of needing more assistance was injury severity (p < 0.05).

Conclusions

An increase in participation restriction and in assistance needs was reported over the 20 year follow-up in persons injured more than 40 years ago. SCI severity was the main risk factor for needing more assistance. Clinical awareness of how participation changes with age may help provide timely intervention and offset declines.

Decision-Making About Upper Limb Tendon Transfer Surgery by People With Tetraplegia for More Than 10 Years

OBJECTIVES

To quantify time from spinal cord injury to upper limb reconstructive surgery for individuals with tetraplegia; to explore influences on decision-making about surgery for persons with long-standing (>10y) tetraplegia; and to determine the applicability of our previously developed conceptual framework that described the decision-making processes for people with tetraplegia of <5 years.

DESIGN

Quantitative-qualitative mixed-methods study.

SETTING

Community based in New Zealand.

PARTICIPANTS

People (N=9) living with tetraplegia for >10 years.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

An audit of time frames between injury, assessment, and surgery for people with tetraplegia was undertaken. Interviews of people with tetraplegia were analyzed using constructivist grounded theory.

RESULTS

Sixty-two percent of people with tetraplegia assessed for surgery had upper limb reconstructive surgery. Most were assessed within the first 3 years of spinal cord injury. Over half had surgery within 4 years after injury; however, 20% waited >10 years. Changes in prioritized activities, and the identification of tasks possible with surgery, were influential in the decision-making process. Participants were aware of surgery, but required a reoffer from health professionals before proceeding. The influence of peers was prominent in reinforcing the improvement in prioritized activities possible after surgery.

CONCLUSIONS

Findings confirmed that the previously developed conceptual framework for decision-making about upper limb reconstructive surgery was applicable for people with tetraplegia of >10 years. Similarities were seen in the influence of goals and priorities (although the nature of these might change) and information from peers (although this influence was greater for those injured longer). Repeat offers for surgery were required to allow for changes in circumstances over time.

Difficulty in Identifying Factors Responsible for Pressure Ulcer Healing in Veterans With Spinal Cord Injury

OBJECTIVE

To identify characteristics associated with pressure ulcer (PrU) healing for individuals with spinal cord injury (SCI).

SETTING

Spinal cord injury centers.

PARTICIPANTS

There were 629 screening and 162 treatment participants (N=791); 185 SCI clinicians/national PrU/wound care experts participated in the Delphi process.

INTERVENTIONS

None.

MAIN OUTCOME MEASURE

PrU healing of 50% and 100% at weeks 4 and 12.

RESULTS

Poisson regression models using the top Delphi-recommended factors found that only ulcer stage consistently predicted 50% and 100% healing at weeks 4 and 12. Additionally, ischial/perineal location was associated with 33% higher likelihood of 50% healing at week 4. Patient noncompliance with treatment recommendations, the top-ranked Delphi factor, did not predict healing at week 4 or 12. Expanded models found that at week 4, baseline PrU size, PrU stage IV, PrU pain, and American Spinal Injury Association grade A significantly predicted 100% healing, while at week 12, only PrU stage (IV) significantly predicted 100% healing. Significant predictors of 50% healing at week 4 included baseline PrU size, stage, ischial/perianal location body mass index >30kg/m², foul odor, and signs of infection. At week 12, PrU duration, paraplegia predicted 50% healing. SCI center identifiers consistently showed 2- to 5-fold variation in predicting 50% PrU healing at weeks 4 and 12.

CONCLUSIONS

Delphi panel-recommended factors (eg, patient compliance) did not predict PrU healing. Reducing center-level variability in wound healing by learning from best practices should be a health system goal. PrU healing in SCI is still poorly understood, and future studies should focus on as yet unidentified or underappreciated factors.

Inpatient migration patterns in persons with spinal cord injury: A registry study with hospital discharge data

This study investigated and compared patient migration patterns of persons with spinal cord injury, the general population and persons with morbid obesity, rheumatic conditions and bowel disease, for secondary health conditions, across administrative boundaries in Switzerland. The effects of patient characteristics and health conditions on visiting hospitals outside the residential canton were examined using complete, nationwide, inpatient health records for the years 2010 and 2011. Patients with spinal cord injury were more likely to obtain treatment outside their residential canton as compared to all other conditions. Facilitators of patient migration in persons with spinal cord injury and the general hospital population were private or accidental health insurances covering costs. Barriers of patient migration in persons with spinal cord injury were old age, severe multimorbidity, financial coverage by basic health insurance, and minority language region.

•

Persons with spinal cord injury were traveling most for inpatient hospital care.

•

Complete or higher-level injuries were associated with more patient migration.

•

Old age and insurance type were strong predictors for receiving local care.

•

Large geographical variability in patient migration patterns was found.

Exercise and sports science Australia (ESSA) position statement on exercise and spinal cord injury

Traumatic spinal cord injury (SCI) may result in tetraplegia (motor and/or sensory nervous system impairment of the arms, trunk and legs) or paraplegia (motor and/or sensory impairment of the trunk and/or legs only). The adverse effects of SCI on health, fitness and functioning are frequently compounded by profoundly sedentary behaviour. People with paraplegia (PP) and tetraplegia (TP) have reduced exercise capacity due to paralysis/paresis and reduced exercising stroke volume. TP often further reduces exercise capacity due to lower maximum heart-rate and respiratory function. There is strong, consistent evidence that exercise can improve cardiorespiratory fitness and muscular strength in people with SCI. There is emerging evidence for a range of other exercise benefits, including reduced risk of cardio-metabolic disease, depression and shoulder pain, as well as improved respiratory function, quality-of-life and functional independence. Exercise recommendations for people with SCI are: ≥30min of moderate aerobic exercise on ≥5d/week or ≥20min of vigorous aerobic ≥3d/week; strength training on ≥2d/week, including scapula stabilisers and posterior shoulder girdle; and ≥2d/week flexibility training, including shoulder internal and external rotators. These recommendations may be aspirational for profoundly inactive clients and stratification into "beginning", "intermediate" and "advanced" will assist application of the recommendations in clinical practice. Flexibility exercise is recommended to preserve upper limb function but may not prevent contracture. For people with TP, Rating of Perceived Exertion may provide a more valid indication of exercise intensity than heart rate. The safety and effectiveness of exercise interventions can be enhanced by initial screening for autonomic dysreflexia, orthostatic hypotension, exercise-induced hypotension, thermoregulatory dysfunction, pressure sores, spasticity and pain.

Effects of prandial challenge on triglyceridemia, glycemia, and pro-inflammatory activity in persons with chronic paraplegia

CONTEXT/OBJECTIVE

Exaggerated postprandial lipemia has been reported after spinal cord injury (SCI). We examined metabolite and accompanying pro-inflammatory biomarker responses to repeat feeding of typical high-fat meals in individuals with chronic paraplegia.

DESIGN

Descriptive trial.

METHODS

Metabolites (triglycerides, glucose, and insulin) and inflammatory biomarkers (interleukin-6 and high-sensitivity C-reactive protein (hsCRP)) were measured under fasting conditions in 11 recreationally active individuals with chronic (>1 year) paraplegia. Subjects received high-fat meals at time point 0 and again at minute 240. Antecubital venous blood was obtained at time points -30 (fasting), 0 (first meal), 30, 60, 90, 120, 240 (second meal), 360, and 480 minutes. Correlations were examined among the study variables. Exploratory subgroup analysis was performed for subjects with levels of postprandial glucose greater than >200 mg/dl.

RESULTS

Triglycerides showed a significant rise 4 hours after eating. Basal inflammatory markers were elevated, and did not undergo additional change during the testing. Additionally, subjects with excessive postprandial glucose responses showed higher hsCRP levels than those having typical glucose responses both for fasting (11.8 ± 6.5 vs. 2.9 ± 2.7 mg/l, P = 0.064) and postprandial (11.1 ± 4.9 vs. 3.7 ± 3.8 mg/l, P = 0.018) values.

CONCLUSIONS

Despite elevations in metabolic response markers, inflammatory markers did not change significantly after consumption of population-representative (i.e. hypercaloric) mixed-nutrient meals. Levels of fasting CRP in the high-risk range are consistent with other reports in persons with SCI and continue to pose concern for their cardiovascular disease risk. The possible association between postprandial metabolic responses and inflammatory states warrants further investigation to identify individual component risks for this secondary health hazard.

Evidence-Based Strategies for Preserving Mobility for Elderly and Aging Manual Wheelchair Users

Elderly and aging manual wheelchair (MWC) users have increased risk for accelerated loss of function and mobility that greatly limits independence and affects quality of life. This review paper addresses important issues for preserving function and mobility for elderly and aging individuals who use a MWC by presenting the current available evidence and recommendations. These include recommendations for maximizing function, by decreasing pain, improving the ability to self-propel, and prolonging mobility and endurance through ergonomics, individualized wheelchair selection and configuration, and adaptations for increasing the capacity to handle the daily mobility demands through training, strengthening, and exercise. Each recommendation is supported by current research in each relevant area.

Factors in rehospitalisation for severe pressure ulcer care in spinal cord injury/disorders

OBJECTIVE

Repeated hospital admissions (RHA) for ongoing pressure ulcer (PU) care remains a significant challenge in the clinical management of the spinal cord injury/disorders (SCI/D) population. The current study investigated the significance of risk factors for PU treatment and RHA.

METHOD

A retrospective chart review of veterans admitted to the Louis Stokes Cleveland Department of Veterans Affairs Medical Center (LSCDVAMC) Spinal Cord Injury (SCI) unit for Category III or IV PUs was carried out. A random sample of 105 individuals with SCI/D, evaluated by the Wound Care Team (WCT) from 2006 to 2009 was assessed. Multiple PU development risk factors were extracted from the electronic health record system using standardised data collection forms and entered into the Spinal Cord Injury Pressure Ulcer Database (SCIPUD). Potential associations with RHA were analysed.

RESULTS

Twenty variables were initially identified as potentially related to PU development. Descriptive statistics and statistically significant associations between risk factors and RHA were determined. Demographic factors showed no significant association with RHA. Duration of injury, power wheelchair use and sub-optimally managed spasticity (SMS) were significantly associated with higher RHA. Sub-optimally managed neurogenic bowel (SMNB) at admission was significantly associated with reduced RHA.

CONCLUSION

Factors previously found to be predictive of initial PU development may not, in fact, be predictive of RHA. Some protective trends were observed, such as polypharmacy and marital status, but these did not reach statistical significance in this preliminary study of admission characteristics, warranting further research.

Psychological distress, quality of life, and burden in caregivers during community reintegration after spinal cord injury

OBJECTIVES

To examine relations between psychological distress, health-related quality of life (HR-QOL), and burden among caregivers of people with traumatic spinal cord injury (SCI) over time, and to determine whether the data are more consistent with a wear and tear or adaptation trajectory.

DESIGN

Prospective longitudinal cohort study with measurements at 4 time points (6wk prior to discharge from subacute inpatient rehabilitation and 6wk, 1y, and 2y postdischarge to community).

SETTING

Rehabilitation units.

PARTICIPANTS

Participants (N=44; spouses, parents, others) nominated as a primary caregiver by the person with SCI.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

General Health Questionnaire-28 (GHQ-28), Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), and Caregiver Strain Index (CSI) assessed the extent of psychological distress, HR-QOL, and burden, respectively, among caregivers. Functional status and community participation/care needs of the persons with SCI were assessed by the FIM and Craig Handicap Assessment and Reporting Technique, respectively.

RESULTS

Multilevel piecewise models showed that psychological distress (GHQ-28 score) decreased significantly after discharge (slope estimate =-.03, P<.008). At the predischarge time point, the caregivers' mental component summary score on the SF-36 was significantly lower than Australian national norms. The scores improved from predischarge to 6 weeks postdischarge (slope estimate =.39, P<.001), but they did not change significantly across the following 2 time points (slope estimate =.02, P=.250). At all 3 postdischarge time points, the mental component summary scores were not significantly different to national norms. In contrast, the physical component summary score of the SF-36 did not significantly change across the predischarge and 6-week postdischarge time points (slope estimate =-.14, P=.121) and the 3 postdischarge time points (slope estimate <.01, P=.947). Scores at all 4 time points were not significantly different to the national norms. Caregiver burden showed no significant change over the study period (predischarge to 6wk postdischarge slope estimate =.02, P=.426; 3 postdischarge time point slope estimates <-.01, P=.334). Reflecting this, 42% of caregivers met CSI caseness criterion at the first time point, and 46% met the criterion at the fourth (2y) time point. Higher burden was significantly correlated with increased hours of care being provided by the caregiver and lower FIM scores and lower community participation (for the person with SCI) at each time point. Psychological distress correlated with caregiver burden at 6 weeks and 1 year postdischarge but not at 2 years postdischarge.

CONCLUSIONS

The trajectory of scores for psychological distress and HR-QOL was consistent with caregiver adaptation to the challenge of providing support to a person with SCI in the early postdischarge period. Caregiver burden did not display similar reductions but did not worsen over the study period.

Additive effect of age on disability for individuals with spinal cord injuries

OBJECTIVE

To examine the additive effect of age on disability for adults with spinal cord injury (SCI).

DESIGN

Prospective cohort study.

SETTING

SCI Model Systems.

PARTICIPANTS

Individuals with SCI (median age at injury, 32 y; range, 6-88 y) with a discharge motor FIM score and at least 1 follow-up motor FIM score who also provided measures of other covariates (N=1660). Of the total sample, 79% were men, 72% were white, 16% had incomplete paraplegia, 33% had complete paraplegia, 30% had incomplete tetraplegia, and 21% had complete tetraplegia.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The primary study outcome was the motor subscale of the FIM. A mixed-models approach was used to examine the additive effect of age on disability for individuals with SCI.

RESULTS

When controlling for motor FIM at discharge from rehabilitation, level and severity of injury, age at injury, sex, race, and the age × time interaction were not significant (P=.07). Age at the time of SCI was significantly associated with motor FIM (F1,238=22.49, P<.001). Two sensitivity analyses found significant interactions for both age × time (P=.03, P=.02) and age × time-square (P=.01, P=.006) models. Trajectory of motor FIM scores is moderated slightly by age at the time of injury. The older participants were at the time of injury, the greater the curvature and the more rapid decline were found in later years.

CONCLUSIONS

These findings indicate that age moderately influences disability for some individuals with SCI: the older the age at the time of injury, the greater the influence age has on disability. The findings serve as an important empirical foundation for the evaluation and development of interventions designed to augment accelerated aging experienced by individuals with SCI.

The effects of aging on upper limb tendon transfers in patients with tetraplegia

PURPOSE

To evaluate the effects of aging on hand function among patients with tetraplegia who had forearm tendon transfer surgery between 1982 and 1990.

METHODS

The study used a longitudinal cohort design that compared hand function outcomes in 2012 with those obtained 11 years earlier. A digital analyzer was used to measure key pinch and grip strength, and results were compared with those obtained in 2001 to determine changes in strength over time. The study also evaluated changes in participant's employment status, wheelchair use, and subjective changes in function using the Lamb and Chan questionnaire.

RESULTS

Participants had a mean key pinch strength force between 11.5 N (tenodeses) and 32.9 N (active transfers) and grip strength forces between 23 N (tenodeses) and 59 N (active transfers). Since 2001, people with active transfers either maintained strength or experienced decreased strength of 5% to 14%. Thumb tenodesis power decreased 40% to 51%, whereas finger tenodeses power increased 32% to 70%. Three activities in the Lamb and Chan questionnaire were identified by the majority of participants as being worse or much worse over the past 11 years. These were performing a pressure relief and propelling a manual wheelchair on level ground and up a ramp. These findings correspond with the increased number of participants who used a power wheelchair in 2012 (64%) compared with 2001 (26%). Close to half of the participants (46%) were employed compared with the 90% in 2001.

CONCLUSIONS

Tendon transfers continued to provide pinch and grip function for individuals with tetraplegia for many years following spinal cord injury. The decrease in strength of those with active transfers over the 11-year period was within the reported aging loss for the normal population. The small number of participants with tenodesis, however, limited our ability to draw meaningful conclusions for this group.

TYPE OF STUDY/LEVEL OF EVIDENCE

Prognostic III.

Age at spinal cord injury determines muscle strength

As individuals with spinal cord injury (SCI) age they report noticeable deficits in muscle strength, endurance and functional capacity when performing everyday tasks. These changes begin at ~45 years. Here we present a cross-sectional analysis of paralyzed thenar muscle and motor unit contractile properties in two datasets obtained from different subjects who sustained a cervical SCI at different ages (≤46 years) in relation to data from uninjured age-matched individuals. First, completely paralyzed thenar muscles were weaker when C6 SCI occurred at an older age. Muscles were also significantly weaker if the injury was closer to the thenar motor pools (C6 vs. C4). More muscles were strong (>50% uninjured) in those injured at a younger (≤25 years) vs. young age (>25 years), irrespective of SCI level. There was a reduction in motor unit numbers in all muscles tested. In each C6 SCI, only ~30 units survived vs. 144 units in uninjured subjects. Since intact axons only sprout 4-6 fold, the limits for muscle reinnervation have largely been met in these young individuals. Thus, any further reduction in motor unit numbers with time after these injuries will likely result in chronic denervation, and may explain the late-onset muscle weakness routinely described by people with SCI. In a second dataset, paralyzed thenar motor units were more fatigable than uninjured units. This gap widened with age and will reduce functional reserve. Force declines were not due to electromyographic decrements in either group so the site of failure was beyond excitation of the muscle membrane. Together, these results suggest that age at SCI is an important determinant of long-term muscle strength, and fatigability, both of which influence functional capacity.

Prevalence, location, grade of pressure ulcers and association with specific patient characteristics in adult spinal cord injury patients during the hospital stay: a prospective cohort study

STUDY DESIGN

This was a prospective cohort study.

OBJECTIVES

The objective was to describe the incidence, prevalence, characteristics of pressure ulcers (PUs) and the association with specific patient characteristics in a consecutive sample of in-patients with a spinal cord injury (SCI).

SETTING

An acute care and rehabilitation clinic specialized in SCIs in Switzerland.

METHODS

The presence and characteristics of PUs for all adult patients with a SCI admitted to the clinic from 1 September 2009 to 28 February 2010 were recorded on a daily basis during their complete hospitalization. Risk factors were analyzed in univariate and multivariate logistic regression models.

RESULTS

A total of 185 patients were included in the study and observed for the entirety of their hospitalization. The prevalence of at least one PU was 49.2% in all patients, compared with 25.4% in the group of patients admitted without PUs. The incidence was 2.2 per person and year. In 91 patients, a total of 219 PUs were observed. PUs were most frequently located on the foot (36.1%), and the coccyx/sacrum (15.1%). The risk for occurrence of a PU increased with age (odds ratio (OR)=1.04) and post SCI (OR=1.03). In the multivariate analyses, the risk for PUs was lower for patients with the American Spinal Injury Association (ASIA) Impairment Scale (AIS) of C or D (ORC=0.25, ORD=0.28) compared with patients with an AIS of A.

CONCLUSION

Using a daily documentation system, PUs were detected as a frequent complication of SCIs. Completeness of injury, age and time since injury were significant risk factors for PUs. The foot was a region at high risk for PUs.

Alterations in mouse hypothalamic adipokine gene expression and leptin signaling following chronic spinal cord injury and with advanced age

Chronic spinal cord injury (SCI) results in an accelerated trajectory of several cardiovascular disease (CVD) risk factors and related aging characteristics, however the molecular mechanisms that are activated have not been explored. Adipokines and leptin signaling are known to play a critical role in neuro-endocrine regulation of energy metabolism, and are now implicated in central inflammatory processes associated with CVD. Here, we examine hypothalamic adipokine gene expression and leptin signaling in response to chronic spinal cord injury and with advanced age. We demonstrate significant changes in fasting-induced adipose factor (FIAF), resistin (Rstn), long-form leptin receptor (LepRb) and suppressor of cytokine-3 (SOCS3) gene expression following chronic SCI and with advanced age. LepRb and Jak2/stat3 signaling is significantly decreased and the leptin signaling inhibitor SOCS3 is significantly elevated with chronic SCI and advanced age. In addition, we investigate endoplasmic reticulum (ER) stress and activation of the uncoupled protein response (UPR) as a biological hallmark of leptin resistance. We observe the activation of the ER stress/UPR proteins IRE1, PERK, and eIF2alpha, demonstrating leptin resistance in chronic SCI and with advanced age. These findings provide evidence for adipokine-mediated inflammatory responses and leptin resistance as contributing to neuro-endocrine dysfunction and CVD risk following SCI and with advanced age. Understanding the underlying mechanisms contributing to SCI and age related CVD may provide insight that will help direct specific therapeutic interventions.

Predictors of changes in sentimental and sexual life after traumatic spinal cord injury

OBJECTIVE

To investigate changes and identify predictors in interpersonal functioning and sexual life after traumatic spinal cord injury (SCI).

DESIGN

Prospective, multicenter, follow-up observational study.

SETTING

Subjects at home, interviewed by phone during a 6-month period, 3.8 mean years after discharge from 24 centers participating in a previous epidemiologic prospective survey.

PARTICIPANTS

Subjects (N=403) with traumatic SCI.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

DEPENDENT VARIABLES

satisfaction with sentimental life and satisfaction with sexual life compared with before the injury.

INDEPENDENT VARIABLES

demographic (age, sex, marital status, vocational status), SCI related (severity, level, bowel/bladder continence), car-driving ability, perceived quality of life (QoL), and impact of sentimental life, social integration, and vocational status on QoL.

RESULTS

Satisfaction with sentimental life was reportedly increased or the same as before SCI in 69% of the sample, but satisfaction with sexual life in only 31%. Lesser satisfaction with sexual life was reported by men than women (P=.002) and by married people than singles (P<.001). Significant predictors of sentimental life were perceived QoL and preserved driving ability (R(2)=.195). Bladder continence was positively associated with a better satisfaction with sexual life (R(2)=.368). Bowel continence did not remain a significant predictor of satisfaction with sexual life in multivariate analysis.

CONCLUSIONS

The challenge of a comprehensive rehabilitation of SCI, addressing the recovery of well-being including a satisfying sentimental and sexual life, requires identifying new issues that should be considered in up-to-date rehabilitation programs. The results indicate associations between driving ability and a better satisfaction with sentimental life. Further investigations are needed to explore whether the relationship is causative.

An evidence-based review on the influence of aging with a spinal cord injury on subjective quality of life

STUDY DESIGN

Systematic review.

OBJECTIVES

To identify changes in subjective quality of life (QoL) as one ages with a spinal cord injury (SCI).

SETTING

Vancouver, Canada.

METHODS

Electronic databases were searched for studies reporting on age-related QoL changes over time. Data from relevant studies were transcribed into data extraction forms and analyzed by years post injury (YPI) and chronologic age. Each study was assigned a level of evidence based on a modified Sackett scale.

RESULTS

In all, 21 studies, each with a low level of evidence, were included for review. The results indicated that regardless of chronologic age, individuals with relatively new SCI have the potential to improve their QoL. Among individuals with advanced YPI, overall QoL is consistently reported as good or excellent over time, however, with variations in different QoL domains.

CONCLUSION

The QoL of individuals aging with a SCI has the potential to improve, and remain high and stable over time. As the identified studies provide low levels of evidence, more longitudinal research with greater methodological and measurement rigor is needed to corroborate the findings and conclusions of this review.

Pulsatile lavage for the enhancement of pressure ulcer healing: a randomized controlled trial

BACKGROUND

Pressure ulcer development is a common, serious complication after spinal cord injury (SCI). Although many biophysical agents are available for treatment, few randomized controlled trials of their efficacy have been done.

OBJECTIVE

The study objective was to examine the efficacy of low-pressure pulsatile lavage treatment for stage III and IV pressure ulcers in people with SCI.

DESIGN

This study was a randomized controlled trial. Participants and assessors were unaware of intervention assignments.

SETTING

This study was conducted in an SCI tertiary care center inpatient unit.

PARTICIPANTS

Participants were 28 people with SCI and stage III and IV pelvic pressure ulcers; 14 participants each were randomly assigned to treatment and control (sham treatment) groups.

INTERVENTION

Daily low-pressure pulsatile lavage treatment with 1 L of normal saline at 11 psi of pressure was applied to the treatment group along with standard dressing changes. The control group received only sham treatment and standard dressing changes.

MEASUREMENTS

Linear and volume measurements of pressure ulcer dimensions were obtained weekly for 3 weeks.

RESULTS

Statistical analysis with the t test revealed no statistically significant difference in demographics between groups. Random-coefficient models for analysis of linear and volume measurements revealed improvements over time for both groups. Time trend analysis revealed greater measurement decreases for the treatment group. Differences in rates of change (with 95% confidence intervals) for treatment and control groups, respectively, were: depth, -0.24 (0.09 to -0.58) cm/wk; width, -0.16 (0.06 to -0.39) cm/wk; length, -0.47 (0.18 to -1.12) cm/wk; and volume, -0.33 (0.13 to -0.80) cm(3)/wk.

LIMITATIONS

Study limitations were small sample size and inclusion of only one site. Additionally, participants were not queried about their group assignments.

CONCLUSIONS

Pulsatile lavage enhanced stage III and IV pelvic pressure ulcer healing rates in people with SCI relative to standard pressure ulcer treatment alone.

Impact of a multicomponent support services program on informal caregivers of adults aging with disabilities

A multicomponent support services program was implemented for veterans aging with disabilities and their informal caregivers (n = 42 dyads). Caregiver outcomes (satisfaction, physical and mental health status, burden, and benefits) were evaluated before and after program use. Caregivers reported significant improvements in mental health post-program. Caregivers who provided care to individuals with impaired physical health experienced meaningful improvements in burden after the support services were rendered. Supporting caregiver health status through such programs is vital to preserve noninstitutional long-term care for persons aging with disabilities, particularly when care is provided over many years to an individual with physical impairments.

Design of the Swiss Spinal Cord Injury Cohort Study

The overall goal of the Swiss Spinal Cord Injury Cohort Study (SwiSCI) is to gain a better understanding of how to support functioning, health maintenance, and quality-of-life of persons with spinal cord injury (SCI) along the continuum of care, in the community, and along their life span. The purpose of this study was to present the SwiSCI study design. SwiSCI is composed of three complementary pathways and will include Swiss persons 16 yrs or older who have diagnoses of traumatic or nontraumatic SCI. Pathway 1 is a retrospective study of medical files of patients admitted to one of the collaborating SCI centers between 2005 and 2009. Pathway 2 is a nationwide survey of persons with chronic SCI. Pathway 3 is an inception cohort study including persons with newly acquired SCI. SwiSCI is conducted in collaboration with the Swiss Paraplegic Association and the major specialized rehabilitation centers in Switzerland. Measurement instruments that are to be used in Pathway 2 and 3 cover body structures and functions, activities, participation, life satisfaction, and personal and environmental factors. SwiSCI is a prospective cohort study that will contribute to a comprehensive understanding of the lived experience of persons with SCI.
