Impact of impairment and secondary health conditions on health preference among Canadians with chronic spinal cord injury

COVID-19 and Mortality in the Spinal Cord Injury Population: Examining the Impact of Sex, Mental Health, and Injury Etiology

BACKGROUND/OBJECTIVE

The purpose of this study was to investigate the impact of the COVID-19 pandemic on mortality rates in a community-dwelling spinal cord injury (SCI) population in Ontario.

METHODS

Using health administrative databases, monthly mortality rates were evaluated pre-pandemic, during the pandemic, and post-pandemic from March 2014 to May 2024. Data were stratified by sex, injury etiology, and mental health status. Group differences were evaluated using t-tests. Autoregressive integrated moving average (ARIMA) models evaluated the pandemic's impact on mortality rates.

RESULTS

A significant increase of 21.4% in mortality rates during the pandemic was found for the SCI cohort. With the exception of the traumatic group, all subgroups also experienced a significant increase in mortality rates (males: 13.9%, females: 31.9%, non-traumatic: 32.3%, mental health diagnoses: 19.6%, and mental health diagnoses: 29.4%). During the pandemic, females had a significantly higher mortality rate than males. The non-traumatic group had higher mortality rates than the traumatic group at all time periods. Individuals with mental health diagnoses had higher mortality rates than those without at the pre-pandemic and pandemic periods.

CONCLUSIONS

The variation in mortality rates across groups highlights inequitable access to medical care in the SCI population, with further research and interventions needed.

Reducing endocrine metabolic disease risk in adults with chronic spinal cord injury: strategic activities conducted by the Ontario-Quebec RIISC team

PURPOSE

The Rehabilitation Interventions for Individuals with a Spinal Cord Injury in the Community (RIISC) team aimed to develop and evaluate innovative rehabilitation interventions to identify endocrine metabolic disease (EMD) risk, intending to reduce the frequency and severity of EMD related morbidity and mortality among adults living with chronic spinal cord injury or disease (SCI/D).

MATERIALS AND METHODS

An interprovincial team from Ontario and Quebec reviewed available EMD literature and evidence syntheses and completed an inventory of health services, policies and practices in SCI/D care. The review outcomes were combined with expert opinion to create an EMD risk model to inform health service transformation.

RESULTS

EMD risk and mortality are highly prevalent among adults with chronic SCI/D. In stark contrast, few rehabilitation interventions target EMD outcomes. The modelled solution proposes: 1) abandoning single-disease paradigms and examining a holistic perspective of the individual's EMD risk, and 2) developing and disseminating practice-based research approaches in outpatient community settings.

CONCLUSIONS

RIISC model adoption could accelerate EMD care optimization, and ultimately inform the design of large-scale longitudinal pragmatic trials likely to improve health outcomes. Linking the RIISC team activities to economic evaluations and policy deliverables will strengthen the relevance and impact among policymakers, health care providers and patients.

Impact of secondary health conditions on the quality of life and wellbeing of Canadians living with spinal cord injury: A comparison of preference-weighted index scores derived from generic standardized instruments

CONTEXT/OBJECTIVES

To compare the assessment of the impact of secondary health conditions (SHCs) on the quality of life and wellbeing of Canadians living with spinal cord injury (SCI) using four preference-based outcome measures.

DESIGN

Secondary analysis of data from a cross-sectional, online survey.

SETTING

Community.

PARTICIPANTS

Community-dwelling adults (n = 364) living with traumatic or non-traumatic spinal cord injury at least one year post-injury (70% at least 10 years post-injury).

OUTCOME MEASURES

A modified version of the Spinal Cord Injury Secondary Conditions Scale (SCI-SCS); three health-related instruments (EQ-5D-5L, Health Utilities Index Mark 3 (HUI3), and the Assessment of Quality of Life 8-dimension questionnaire (AQoL-8D)) and a capability wellbeing instrument (ICEpop CAPability measure for Adults (ICECAP-A)).

RESULTS

Across unadjusted and controlled analyses (i.e. controlling for associations between index scores and sociodemographic and impairment characteristics), trends were observed that identified lower levels of quality of life/wellbeing with higher problem ratings for each of the SHCs. Despite the trends, there was considerable variation in mean index scores across instruments, with HUI3 scores the lowest of the health-related instruments and ICECAP-A scores the highest overall. Respiratory problems, depression/mood problems, pressure sores, and autonomic dysreflexia were associated with the lowest levels of quality of life and wellbeing.

CONCLUSIONS

Higher problem ratings for SHCs are negatively associated with scores derived from preference-based quality of life and wellbeing instruments. Variation in index scores across instruments - including across the health-related instruments alone - highlights the critical importance of assessing the relative merits of preference-based instruments when using (or considering using) these instruments/estimates in comparative effectiveness research and economic evaluation.

Bowel burdens: a systematic review and meta-analysis examining the relationships between bowel dysfunction and quality of life after spinal cord injury

STUDY DESIGN

Systematic review and meta-analysis.

OBJECTIVES

Many individuals with spinal cord injury (SCI) experience autonomic dysfunction, including profound impairments to bowel and cardiovascular function. Neurogenic bowel dysfunction (NBD) is emerging as a potential determinant of quality of life (QoL) after SCI. For individuals with high-level lesions ( > T6), bowel care-related autonomic dysreflexia (B-AD; profound episodic hypertension) further complicates bowel care. We aimed to evaluate the extent of bowel dysfunction after SCI, and the impact of bowel dysfunction on QoL after SCI.

METHODS

We searched five databases to identify research assessing the influence of NBD or B-AD on QoL after SCI. Metrics of bowel dysfunction (fecal incontinence [FI], constipation, time to complete, and B-AD) and QoL data were extracted and synthesised. Where possible, meta-analyses were performed.

RESULTS

Our search identified 2042 titles, of which 39 met our inclusion criteria. Individuals with SCI identified problems with NBD (74.7%), FI (56.9%), and constipation (54.6%), and 49.3% of individuals with SCI > T6 experienced B-AD. Additionally, 40.3% of individuals experienced prolonged defecation ( > 30 min). Moderate/severe deterioration in QoL due to NBD was reported by 55.5% of individuals with SCI, with negative impacts on physical, emotional, and social health-related QoL associated with inflexibility of bowel routines, fear of accidents, and loss of independence.

CONCLUSION

Bowel dysfunction and bowel care challenges are prevalent and disabling for individuals with SCI, with a profoundly negative impact on QoL. Improving bowel management is a key target to improve QoL for those living with SCI.

Factors enabling comorbidities and secondary conditions in older adults with spinal cord injury

OBJECTIVE

To examine the role of personal, social, and environmental factors predicting comorbidities and secondary conditions among older adults with spinal cord injury (SCI).

DESIGN

Cross-sectional study utilizing survey methods were used to collect the data analyzed with two distinct general linear models.

SETTING

Community-dwelling participants who resided in rural and urban areas.

PARTICIPANTS

One hundred and eighty-three (183) participants with SCI ages 45 and over at least five years post injury.

INTERVENTIONS

Not applicable.

MEASURES

Spinal Cord Injury Secondary Conditions Scale (SCI-SCS); Comorbidities Questionnaire; Spinal Cord Injury Functional Index Assistive Technology (SCI-FI/AT) Basic - Mobility; Spinal Cord Injury Quality of Life (SCI-QOL) Satisfaction with Social Roles and Activities Scale (SSRA); Cohen's Social Network-Social Integration Index, the Medical Outcomes Study (MOS) Social Support Emotional/Informational Support Scale, and the Facilitators and Barriers Survey for Mobility (FABS-Mv2). Questions were also asked from the Behavioral Risk Factor Surveillance System (BRFSS).

RESULTS

Common predictors of comorbidities and secondary conditions included age, basic mobility, primary health care payer and parking limitations. An interaction between parking and neurological classification was observed for comorbidities. Neurological classification and employment were significantly associated with comorbidities while for secondary conditions, sex, years since injury, education, satisfaction with social roles and the home environment were critical factors.

CONCLUSIONS

Our study shows the effects of demographic and injury factors, physical functioning, satisfaction with social roles, access to home environment adaptations and health resources in predicting comorbidities and secondary conditions among older adults with SCI.

Cannabis health survey on usage in women with spinal cord injury and knowledge among physicians: A cross-sectional study

OBJECTIVE

Individuals with spinal cord injury (SCI) report using cannabis to self-manage chronic pain and spasticity. However, its safety and efficacy are not well understood. As more women with SCI are pursuing motherhood, clinicians must consider the possibility of maternal cannabis use and its impact on fetal development. Moreover, due to the lack of current evidence for cannabis, it is important to characterize the perceptions and knowledge of physicians towards both recreational and synthetic cannabinoids.

DESIGN

Two anonymous surveys (10-items each) were conducted.

SETTING AND PARTICIPANTS

Women with SCI (n = 20) completed an anonymous, online survey regarding cannabis use. Physicians at a Canadian SCI rehabilitation center (n = 15) completed a survey on their knowledge of recreational and synthetic cannabinoids among individuals with SCI.

OUTCOME MEASURES

Survey 1 evaluated cannabis use patterns and perceptions before/after SCI in women, including during pregnancy and breastfeeding. The aim of Survey 2 was to understand the perception and current knowledge of physicians regarding recreational cannabis and synthetic cannabinoid use by patients with SCI.

RESULTS

At the time of survey, 7 women with SCI reported use of cannabis, only 4 of them used prior to injury. Managing tone/spasticity (n = 5) was the major reported benefit of cannabis use. Women used cannabis during pregnancy and/or breastfeeding as a sleep aid or relief for morning sickness (n = 1 pregnancy, n = 1 breastfeeding, n = 1 both). The most-reported challenge with cannabis use was difficulty obtaining consistent, desirable effects (n = 5). Almost all physicians (n = 13) described their knowledge on recreational cannabis products as "none, very little or poor", with greater overall comfort and knowledge of synthetic cannabinoids.

CONCLUSION

Due to the reported use of cannabis during pregnancy/breastfeeding and current impoverishment of physicians' knowledge (particularly regarding recreational cannabis products), it is imperative to further investigate the safety and efficacy of cannabis use in women with SCI.

Health utility in community-dwelling adults with dysvascular lower limb loss

PURPOSE

Adults with dysvascular lower extremity amputation (LEA) experience a large number of secondary health conditions yet there is a gap in the literature on health utility scores for this population. A health utility score relates to a person's state of well-being, and is a single metric anchored at 0 (death) and 1 (perfect health). This study aimed to provide a descriptive account of health utility scores in community-dwelling adults with dysvascular LEA.

METHODS

Participants were adults with dysvascular LEA who were 3 months post-amputation. Data collected included socio-demographic characteristics, the Special Interest Group in Amputee Medicine (SIGAM) grades, the dysvascular conditions scale (DCS), which is a scale developed for this study, and the Short Form-36 (SF-36). SF-6D health utility scores were derived from the SF-36 using a software algorithm. Participants were grouped into low-impact and high-impact groups based on self-reported severity of symptoms using the DCS. Health utility scores were compared between the low-impact and high-impact groups using independent t-tests.

RESULTS

A total of 231 participants were enrolled in the study. The mean SF-6D health utility score was 0.689 (0.127). A significant association was found between health utility score and SIGAM grade (p < 0.001, η2 = .09). Health utility was positively associated with age (r = 0.137, p = 0.037) and months post-amputation (r = 0.141, p = 0.032), and negatively associated with DCS severity (r = -0.526, p < 0.001). Health utility scores were lower for participants in the DCS high-impact groups for conditions such as diabetes mellitus, phantom limb pain, musculoskeletal pain, back pain, psychological distress, depression, vision problems, and other pain.

CONCLUSION

Cost-utility analyses rely on health utility estimates and our findings provide data for future economic evaluations that may assist policy makers in evidence informed allocation of healthcare resources for this population.

The Effects of APP-Based Intervention for Depression Among Community-Dwelling Individuals With Spinal Cord Injury: A Randomized Controlled Trial

OBJECTIVE

To assess the effect of a self-management intervention delivered by mobile application (APP) for depression among community-dwelling individuals with spinal cord injury (SCI).

DESIGN

Randomized controlled trial.

SETTINGS

General communities in China.

PARTICIPANTS

Community-dwelling individuals with SCI who were diagnosed within 2 years were recruited in this study (N=98). It was a convenience sample with an average age of 41.71, 82.7% participants were men.

INTERVENTIONS

Participants in the intervention group (n=49) received 5 sessions on self-management training provided by nurse-led multidisciplinary team via APP at the second, fourth, sixth, eighth, and 12th weeks, respectively, after they discharge from hospitals. Participants in the control group (n=49) received routine telephone counselling provided by follow-up nurses at the 12th week after they discharge.

OUTCOME MEASURE

The outcome of this study is depression, which is not the primary outcomes in the registration of this program. Depression was measured by version 2 of Beck Depression Inventory at discharge (T₀), the 12th week after discharge from hospitals (T₁), and the 24th week after discharge from hospitals (T₂).

RESULTS

There were 98 participants (49 in the intervention group and 49 in the control group) completing the intervention and data collection. Compared with the control group, the intervention group had lower level of depression at T2 (B=-5.76; 95% CI=-9.97, -1.54; P=.007). Small to moderate effect sizes on depression favoring the intervention were demonstrated at T₁ (Cohen's d=-.178) and T₂ (Cohen's d=-.535).

CONCLUSIONS

APP-based self-management support can be a potential intervention to reduce depression among community-dwelling individuals with SCI.

Effect of the COVID-19 pandemic on individuals with spinal cord injury: Mental health and use of telehealth

INTRODUCTION

Limited access to health care services and the self-isolation measures due to the coronavirus disease 2019 (COVID-19) pandemic may have had additional unintended negative effects, affecting the health of individuals with spinal cord injury (SCI).

OBJECTIVES

To examine the perceived influence of the COVID-19 pandemic on individuals with SCI. First, this study looked to understand how the pandemic affected the use and perception of telehealth services for these individuals. Second, it investigated the effect of COVID-19 on mental health.

DESIGN

Cross-sectional online survey.

SETTING

Individuals with SCI living in the community in British Columbia, Canada.

PATIENTS

This survey was offered to individuals with SCI and had 71 respondents, with 34% living in a rural setting and 66% in an urban setting.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Telehealth utility, Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder 7 (GAD-7), Fear of COVID-19 scale (FCV-19S), and Perceived Vulnerability to Disease (PVD).

RESULTS

Telehealth use in the SCI population has increased from 9.9% to 25.4% over the pandemic, with rates of telehealth use in urban centers nearing those of rural participants. Thirty-one percent of respondents had probable depression and 7.0% had probable generalized anxiety disorder as measured by a score of ≥10 on the PHQ-9 and GAD-7, respectively. The mean scores on FCV-19S and PVD were 17.0 (6.6 SD) and 4.29 (1.02 SD), respectively.

CONCLUSION

Telehealth use during COVID-19 has more than doubled. It is generally well regarded by respondents, although only a fourth of the SCI population has reported its use. With this in mind, it is important to understand the barriers to further adoption. In addition, higher rates of probable depression were seen than those estimated by pre-pandemic studies in other countries.

Physical activity and life satisfaction among individuals with spinal cord injury: Exploring loneliness as a possible mediator

Context: There has been no known research investigating the association between leisure time physical activity (LTPA), loneliness, and life satisfaction among people with spinal cord injury or dysfunction (SCI/D). The relationship between these constructs is worthy of consideration given the positive health impacts of LTPA, the negative health impacts of loneliness, and heightened negative effects of loneliness on life satisfaction for individuals with SCI/D.Objectives: To examine the relationship between LTPA and loneliness, and examine loneliness as a possible mediator of the relationship between LTPA and life satisfaction among individuals with SCI/D.Design and Participants: Community dwelling individuals with SCI/D (N = 170) participated in a telephone-based survey as part of a larger project.Measures: LTPA (i.e. The Leisure Time Physical Activity Questionnaire-SCI, UCLA Loneliness Scale-3, and the Life Satisfaction Questionnaire-11 were administered to the participants.Results: Significant bivariate relationships were observed between LTPA and life satisfaction (r = .18, P = .02), LTPA and loneliness (r = -.15, P = .045), and loneliness and life satisfaction (r = -.69, P < .001). Mediation analyses suggest that loneliness significantly mediated the relationship between LTPA and life satisfaction (indirect effect = .003, 95% bootstrap CI = .0004 to .0062, CSI = .113).Conclusion: This was the first study to show evidence of a negative association between LTPA and loneliness among people with SCI/D, and to establish a conceptual model for understanding the potential mediating role of loneliness in the relationship between LTPA and life satisfaction among people with SCI/D.

Impact of Heterotopic Ossification on Functional Recovery in Acute Spinal Cord Injury

Objective: In spinal cord injury (SCI), heterotopic ossification is a frequent secondary complication, commonly associated with limited range of motion of affected joints, which could lead to secondary disability in activities of daily living. Additionally, heterotopic ossifications might challenge the effect of regeneration-promoting therapies on neurological and functional recovery. This study evaluated the impact of heterotopic ossification on clinical recovery within the first year after SCI.

Methods: The study was conducted as a monocentric longitudinal paired cohort study. Recruitment was based on consecutive sampling in the framework of the European Multicenter about Spinal Cord Injury (EMSCI). Recovery profiles were determined using standardized neurological and functional clinical assessments within the 1st year following SCI. All study participants underwent at least two comprehensive standardized neurological and functional clinical examinations according to the International Standards for Neurological Classification of SCI and the Spinal Cord Independence Measure, respectively. Data regarding the diagnosis and treatment of heterotopic ossification were obtained by reviewing the patient medical records. The most similar “digital twin” from the entire EMSCI database were matched in terms of age, acute neurological and functional status to each individual with SCI, and heterotopic ossification.

Results: Out of 25 participants diagnosed with heterotopic ossification, 13 individuals were enrolled and matched to control individuals. Most individuals presented with motor complete injury (75%). Ossifications were most frequently located at the hip joints (92%) and mainly occurred within the first 3 months after SCI. Individuals with heterotopic ossification achieved around 40% less functional improvement over time compared to their matched counterparts, whereas neurological recovery was not altered in individuals with SCI and heterotopic ossification.

Conclusion: Heterotopic ossification—a common complication of SCI—unfavorably affects functional recovery, which in the end is most relevant for the best possible degree of independence in activities of daily living. Upon presentation with heterotopic ossification, neurological improvement achieved through potential restorative therapies might not translate into clinically meaningful functional improvement. Diagnostic algorithms and effective early prevention/treatment options for heterotopic ossification need to be established to ensure the best possible functional outcome.

Clinical Trial Registration: NCT01571531 (https://clinicaltrials.gov).

Corticospinal modulation of vibration-induced H-reflex depression

The purpose of this study was to examine corticospinal modulation of spinal reflex excitability, by determining the effect of transcranial magnetic stimulation (TMS) on soleus H-reflexes while they were almost completely suppressed by lower extremity vibration. In 15 healthy adults, a novel method of single-limb vibration (0.6 g, 30 Hz, 0.33 mm displacement) was applied to the non-dominant leg. Soleus muscle responses were examined in six stimulation conditions: (1) H-reflex elicited by tibial nerve stimulation, (2) tibial nerve stimulation during vibration, (3) subthreshold TMS, (4) subthreshold TMS during vibration, (5) tibial nerve stimulation 10 ms after a subthreshold TMS pulse, and (6) tibial nerve stimulation 10 ms after a subthreshold TMS pulse, during vibration. With or without vibration, subthreshold TMS produced no motor evoked potentials and had no effect on soleus electromyography (p > 0.05). In the absence of vibration, H-reflex amplitudes were not affected by subthreshold TMS conditioning (median (md) 35, interquartile range (IQ) 18-56 vs. md 46, IQ 22-59% of the maximal M wave (Mmax), p > 0.05). During vibration, however, unconditioned H-reflexes were nearly abolished, and a TMS conditioning pulse increased the H-reflex more than fourfold (md 0.3, IQ 0.1-0.7 vs. md 2, IQ 0.9-5.0% of Mmax, p < 0.008). Limb vibration alone had no significant effect on corticospinal excitability. In the absence of vibration, a subthreshold TMS pulse did not influence the soleus H-reflex. During limb vibration, however, while the H-reflex was almost completely suppressed, a subthreshold TMS pulse partially restored the H-reflex. This disinhibition of the H-reflex by a corticospinal signal may represent a mechanism involved in the control of voluntary movement. Corticospinal signals that carry the descending motor command may also reduce presynaptic inhibition, temporarily increasing the impact of sensory inputs on motoneuron activation.

Cognitive function, quality of life, and aging: relationships in individuals with and without spinal cord injury

Background: Correlations between aging, cognitive impairment and poor quality of life (QOL) have been observed for many patient populations.Objective: The purpose of this study was to examine these correlations in individuals with and without spinal cord injury (SCI).Methods: 23 individuals with complete SCI and 20 individuals without SCI ("NON") underwent assessment of cognitive function via the NIH Toolbox for Neurological and Behavioral Function. Participants self-rated QOL via global and symptom/domain-specific measures.Results: SCI rated global QOL to be lower than NON for the EQ-5D QALY (p < .001), but not the EQ-5D VAS, which imposes no penalty for wheeled mobility. Low QOL clustered mainly in domains pertaining to physical function/symptoms. Participants with SCI reported high QOL for positive affect/well-being and resilience. Cognitive function in SCI did not differ from NON. However, strong correlations between age and cognition observed in NON (all R² > 0.532) were absent in SCI. Significant correlations between cognition and QOL were prevalent for NON but not for SCI.Conclusions: Dissociation of age, cognition and QOL occurred with SCI. Divergence between EQ-5D QALY and VAS suggests that individuals with SCI may recalibrate personal assessments of QOL in ways that minimize the importance of mobility impairment.

Central Recruitment: A process for engaging and recruiting individuals with spinal cord injury/disease in research at Toronto Rehabilitation Institute

CONTEXT

Insufficient recruitment is a barrier to research and limits statistical power. We describe an initiative aimed to streamline recruitment and consent processes for inpatients with spinal cord injury or disease (SCI/D) via implementation of a Central Recruitment (CR) process. The CR process adhered to ethical standards, reduced participant burden, and maximized research participation.

METHODS

In this CR process, the inpatient's nurse affirmed suitability for research approach based on fluency, cognition and health stability. A patient research liaison (PRL) was the sole contact for information regarding the research process, and introduced ongoing studies, screened for eligibility, and completed the consent process(es).

RESULTS

Over five and a half years, 1,561 inpatients with SCI/D were screened for eligibility upon admission, of whom 80% (1256/1561) were deemed suitable for the PRL approach. Of those suitable for the CR process, 80% (1001/1256) agreed to discuss current research opportunities, 46% (235/516) consented to participate in one or more studies, and 86% (856/1001) agreed to future research contact.

CONCLUSION

This process adhered to ethical procedures and reduced the burden of having multiple researchers approach each individual inpatient regarding research participation, with high consent rates for low-risk studies. Future evaluation of the process scalability is underway.

Prevalence of comorbidities and secondary health conditions among the Finnish population with spinal cord injury

Study design

A cross-sectional study.

Objectives

To explore the prevalence of comorbidities, secondary health conditions (SHCs), and multimorbidity in the Finnish population with spinal cord injury (SCI).

Setting

The data were collected from the Finnish Spinal Cord Injury Study (FinSCI). Participants were identified from three SCI outpatient clinics responsible for the lifelong follow-up of persons with SCI in Finland, (n = 884 participants, response rate; 50%).

Methods

The FinSCI-questionnaire included a question from the National Study of Health, Well-being, and Service (FinSote) for screening 12 comorbidities. The reference data of the general population for that question were received from the Finnish Institute for Health and Welfare. The Spinal Cord Injury Secondary Condition Scale (SCI-SCS) was used to screen 16 SHCs. The data were analysed with univariate testing and multivariable negative binomial regression modelling.

Results

The most common comorbidities were high blood pressure/hypertension (38%), back problems (28%), and high cholesterol (22%). The most common SHCs were joint and muscle pain (81%), muscle spasms (74%), chronic pain (71%), and bowel problems (71%). The prevalence of comorbidities was highest among persons aged ≥76 years (mean; 2.0; scale range; 0–12). The prevalence of SHCs was highest in the severity of SCI group C1–4 AIS A, B, and C (mean; 8.9; scale range; 0–16).

Conclusions

Further research on geriatrics in SCI, non-traumatic SCI, and knowledge of the needs of persons with cervical lesion AIS A, B, or C is required, due to the fact that the prevalence of multimorbidity is high in these groups.

Does access to acute intensive trauma rehabilitation (AITR) programs affect the disposition of brain injury patients?

Early incorporation of rehabilitation services for severe traumatic brain injury (TBI) patients is expected to improve outcomes and quality of life. This study aimed to compare the outcomes regarding the discharge destination and length of hospital stay of selected TBI patients before and after launching an acute intensive trauma rehabilitation (AITR) program at King Saud Medical City. It was a retrospective observational before-and-after study of TBI patients who were selected and received AITR between December 2018 and December 2019. Participants’ demographics, mechanisms of injury, baseline characteristics, and outcomes were compared with TBI patients who were selected for rehabilitation care in the pre-AITR period between August 2017 and November 2018. A total of 108 and 111 patients were managed before and after the introduction of the AITR program, respectively. In the pre-AITR period, 63 (58.3%) patients were discharged home, compared to 87 (78.4%) patients after AITR (p = 0.001, chi-squared 10.2). The pre-AITR group’s time to discharge from hospital was 52.4 (SD 30.4) days, which improved to 38.7 (SD 23.2) days in the AITR (p < 0.001; 95% CI 6.6–20.9) group. The early integration of AITR significantly reduced the percentage of patients referred to another rehabilitation or long-term facility. We also emphasize the importance of physical medicine and rehabilitation (PM&R) specialists as the coordinators of structured, comprehensive, and holistic rehabilitation programs delivered by the multi-professional team working in an interdisciplinary way. The leadership and coordination of the PM&R physicians are likely to be effective, especially for those with severe disabilities after brain injury.

Considerations on the psychometric properties and validity of the Spinal Cord Injury Secondary Conditons Scale

STUDY DESIGN

Cross-sectional validation study.

OBJECTIVES

Explore psychometric properties of Spinal Cord Injury Secondary Conditions Scale (SCI-SCS).

SETTING

Two Scandinavian rehabilitation centres.

METHODS

Included were 224 consecutive patients attending regular follow-up at least 1 year after a traumatic SCI. Mean age was 49.6 (SD 14.9) years. SCI-SCS floor and ceiling effect examined. Construct validity was investigated by confirmatory factor analysis and correlation analysis, and reliability by Cronbach's alpha.

RESULTS

SCI-SCS showed no floor or ceiling effect. Two out of four earlier reported latent factors ("Genitourinary and bowel", "Muscle structures and pain") were confirmed. The global Cronbach's alpha of SCI-SCS was 0.65 and 0.22-0.61 for the four latent factors. The SCI-SCS sum score showed low correlation to quality of life (QoL) measured by EQ5 VAS (r_s = -0.47, p < 0.001). Likewise, the sum score correlations to QoL-general and QoL-physical health (International SCI QoL Basic Dataset) were low (r_s = -0.36, p < 0.001 and r_s = -0.37, p < 0.001, respectively). The scale item Muscle Spasms correlated moderately to ratings on Spasm Frequency (r_s = 0.59, p < 0.001) and Spasm Intensity (r_s = 0.56, p < 0.001) scales. Chronic Pain and Joint and Muscle Pain correlated to patient reported number of pain sites and level of pain (International SCI Pain Basic Dataset 1.0) (r_s = 0.31 p < 0.001 and r_s = 0.47, p < 0.001, respectively).

CONCLUSION

SCI-SCS is a relevant instrument for giving clinicians and researchers an overview of the individual recent experiences with secondary conditions. However, the instrument could benefit from a clearer definition of the construct secondary conditions, a scale revision and a consideration of whether to add other experienced secondary conditions.

Examination of the Relationships Among Social Networks and Loneliness on Health and Life Satisfaction in People with Spinal Cord Injury/Dysfunction

OBJECTIVE

To examine the associations among social networks and loneliness on health and life satisfaction in adults with chronic spinal cord injury/dysfunction (SCI/D).

DESIGN

Cross-sectional telephone survey study.

SETTING

Tertiary spinal cord injury rehabilitation center in Ontario, Canada.

PARTICIPANTS

Community-dwelling adults with chronic SCI/D (N=170).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The main outcome measures were the Short-Form 36 to assess health and the Life Satisfaction-11 to assess life satisfaction.

RESULTS

A hierarchical regression model predicting physical health accounted for 24% (P<.001) of the variance. The only social network variable to significantly contribute to the model was having a higher proportion of network members living in one's household (P<.05). A model predicting mental health accounted for 44% (P<.001) of the variance, with having a higher proportion of network members living in one's household (P<.05) and lower feelings of loneliness (P<.001) associated with better mental health. Finally, the model predicting life satisfaction accounted for 62% (P<.001) of the variance, with lower greater levels of social network intimacy (P<.01) and lower feelings of loneliness (P<.001) being significant predictors.

CONCLUSIONS

These findings highlight the importance of having access to network members in one's home for better physical and mental health after SCI/D as well as the negative association between loneliness and mental health and life satisfaction. There is a need for approaches to ensure that people with SCI/D in the community feel supported to mitigate feelings of loneliness to optimize their health and wellbeing.

Secondary health conditions and disability among people with spinal cord injury: A prospective cohort study

Objective: To examine how secondary health conditions (SHCs) that develop early after a spinal cord injury (SCI) are related to disability over time.Design: Prospective cohort study.Setting: Two spinal units in New Zealand (Burwood Spinal Unit and Auckland Spinal Rehabilitation Unit).Participants: Between 2007 and 2009, 91 people participated in three telephone interviews approximately 6, 18, and 30 months after the occurrence of a SCI.Outcome measures: SHCs were measured using 14 items derived from the Secondary Complications Survey. Disability was measured using the 12-item World Health Organization Disability Assessment Schedule 2.0. Linear regression analyses were performed to investigate associations between SHCs at 6 months and disability at each assessment point.Results: The most prevalent SHCs were leg spasms, constipation, back pain, pain below the level of SCI, and shoulder pain. Constipation, urinary tract infection, and headaches at 6 months post-SCI were associated with significantly higher levels of disability at each subsequent follow-up, independent of age, sex and SCI impairment. Back pain, and pain below the SCI, at 6 months were associated with significantly greater disability at 18 months, and difficulty coughing at 6 months was associated with significantly greater disability at 30 months.Conclusion: The experience of specific SHCs in the first 6 months after an SCI is related to greater long-term disability. In order to reduce the disability burden of people with SCI, efforts should be directed toward early prevention of these SHCs.

Musculoskeletal morbidity following spinal cord injury: A longitudinal cohort study of privately-insured beneficiaries

BACKGROUND

People living with spinal cord injuries (SCIs) experience motor, sensory and autonomic impairments that cause musculoskeletal disorders following the injury and that progress throughout lifetime. The range and severity of issues are largely dependent on level and completeness of the injury and preserved function.

OBJECTIVE

High risk of developing musculoskeletal morbidities among individuals after sustaining a traumatic SCI is well known in the clinical setting, however, there is a severe lack of evidence in literature. The objective of this study was to compare the incidence of and adjusted hazards for musculoskeletal morbidities among adults with and without SCIs.

METHODS

Privately-insured beneficiaries were included if they had an ICD-9-CM diagnostic code for SCI (n = 9081). Adults without SCI were also included (n = 1,474,232). Incidence estimates of common musculoskeletal morbidities (e.g., osteoporosis, sarcopenia, osteoarthritis, fractures, etc.) were compared at 5-years of enrollment. Survival models were used to quantify unadjusted and adjusted hazard ratios for incident musculoskeletal morbidities.

RESULTS

Adults living with traumatic SCIs had a higher incidence of any musculoskeletal morbidities (82.4% vs. 47.5%) as compared to adults without SCI, and differences were to a clinically meaningful extent. Survival models demonstrated that adults with SCI had a greater fully-adjusted hazard for any musculoskeletal morbidity (Hazard Ratio [HR]: 2.41; 95%CI: 2.30, 2.52), and all musculoskeletal disorders, and ranged from HR: 1.26 (1.14, 1.39) for rheumatoid arthritis to HR: 7.02 (6.58, 7.49) for pathologic fracture.

CONCLUSIONS

Adults with SCIs have a significantly higher incidence of and risk for common musculoskeletal morbidities, as compared to adults without SCIs. Efforts are needed to facilitate the development of improved clinical screening algorithms and early interventions to reduce risk of musculoskeletal disease onset/progression in this higher risk population.

An exploration of perceived social isolation among persons with spinal cord injury in Ontario, Canada: a qualitative study

PURPOSE

To advance the understanding of perceived social isolation among persons with spinal cord injury (SCI), the objectives of the present study were to explore: (1) experiences of perceived social isolation and (2) factors that contribute to perceived social isolation.

METHODS

Interpretive description qualitative methodology was used to conduct semi-structured interviews with 30 individuals with SCI from across Ontario (Canada) from November 2016 to August 2017. Data were analyzed using thematic analysis.

RESULTS

Participants identified disruption to social networks that seemed to impact perceived social isolation. Five major themes were identified: (1) impact on structure and frequency of social network; (2) importance of feeling heard; (3) importance of employment, hobbies, and sports; (4) need to improve physical accessibility and built environment; and (5) individual characteristics. Changes in quality of social networks, rather than size, contributed to greater feelings of perceived social isolation. The built environment, maintenance of employment, hobbies, and sports, social media, and technology use, as well as individual traits, were also found to impact perceived social isolation.

CONCLUSION

Future research should focus on the development of programs to help maintain or improve social network quality for persons with SCI to minimize the impact of perceived social isolation.IMPLICATIONS FOR REHABILITATIONPerceived social isolation, resulting from physical and environmental barriers, is a challenge that is faced by many individuals who are living in the community with a spinal cord injury (SCI).Rehabilitation and community programs should utilize an individualized approach to find solutions to challenges faced by this population to prevent the effects of perceived social isolation.Education on how to adapt to changes in social network, together with the provision of access to peer-to-peer support groups, and SCI specific return to work or leisure programs, is recommended as an essential component of rehabilitation.

Empirical Validity of a Generic, Preference-Based Capability Wellbeing Instrument (ICECAP-A) in the Context of Spinal Cord Injury

BACKGROUND

Assessing the validity of generic instruments across different clinical contexts is an important area of methodological research in economic evaluation and outcomes measurement.

OBJECTIVE

Our objective was to examine the empirical validity of a generic, preference-based capability wellbeing instrument (ICECAP-A) in the context of spinal cord injury.

METHODS

This study consisted of a secondary analysis of data collected using an online cross-sectional survey. The survey included questions regarding demographics, injury classifications and characteristics, secondary health conditions, quality of life and wellbeing, and functioning in activities of daily living. Analysis comprised the descriptive assessment of Spearman's rank correlations between item-/dimension-level data for the ICECAP-A and four preference-based health-related quality of life (HRQoL) instruments, and discriminant and convergent validity approaches to examine 21 evidence-informed or theoretically derived constructs. Constructs were defined using participant and injury characteristics and responses to a range of health, wellbeing and functioning outcomes.

RESULTS

Three hundred sixty-four individuals completed the survey. Mean index score for the ICECAP-A was 0.761; 12 (3%) individuals reported full capability (upper anchor; score = 1), and there were no reports of zero capabilities (lower anchor; score = 0). The strongest correlations were dominated by items and dimensions on the comparator (HRQoL) instruments that are non-health aspects of quality of life, such as happiness and control over one's life (including self-care). Of 21 hypothesised constructs, 19 were confirmed in statistical tests, the exceptions being the exploratory hypotheses regarding education and age at injury.

CONCLUSION

The ICECAP-A is an empirically valid outcome measure for assessing capability wellbeing in people with spinal cord injury living in a community setting. The extent to which the ICECAP-A provides complementary information to preference-based HRQoL instruments is dependent on the comparator.

Frequency of patient-reported UTIs is associated with poor quality of life after spinal cord injury: a prospective observational study

STUDY DESIGN

Cross-sectional survey of the Neurogenic Bladder Research Group (NBRG) registry; a multicenter prospective observation study.

OBJECTIVES

To assess how patient-reported urinary tract infections (PRUTIs) in spinal cord injury (SCI) affect quality of life (QOL).

SETTING

Multiple United States hospitals.

METHODS

1479 participants with SCI were asked about neurogenic bladder-related QOL. Eligibility: age ≥ 18 years with acquired SCI. PRUTI frequency over the last year was classified as 0, 1-3, 4-6, or >6. Four UTI QOL domains were assessed: (1) UTIs limited daily activities, (2) UTIs caused increased muscle spasms, (3) UTIs would not go away, and (4) UTIs made me avoid going out. Multivariable regression identified variables associated with poor QOL.

RESULTS

PRUTI frequency was 0 in 388 patients (26%), 1-3 in 677 (46%), 4-6 in 223 (15%), and more than 6 in 190 (13%). Increasing PRUTI rate was independently associated with worse QOL for all four questions. Compared with those with 0 PRUTIs, participants reporting >6 were more likely to limit daily activities (OR 9.0 [95% CI 8.1-21.2] p < 0.0001), experience increased muscle spasms (OR 12.4 [95% CI 7.5-20.6] p < 0.0001), perceive a UTI would not go away (OR 30.1 [95% CI 15.0-60.4] p < 0.0001), and avoid going out because of UTIs (OR 7.2 [95% CI 4.2-12.4] p < 0.0001).

CONCLUSIONS

An increasing rate of PRUTIs is independently associated with worse QOL. Thorough evaluation and treatment may improve QOL in this population.

A Scoping Review of Self-Management Interventions Following Spinal Cord Injury

Objective: To conduct a scoping review to identify what components of self-management are embedded in self-management interventions for spinal cord injury (SCI). Methods: In accordance with the approach and stages outlined by Arksey and O'Malley (2005), a comprehensive literature search was conducted using five databases. Study characteristics were extracted from included articles, and intervention descriptions were coded using Practical Reviews in Self-Management Support (PRISMS) (Pearce et al, 2016), Barlow et al (2002), and Lorig and Holman's (2003) taxonomy. Results: A total of 112 studies were included representing 102 unique self-management programs. The majority of the programs took an individual approach (52.0%) as opposed to a group (27.4%) or mixed approach (17.6%). While most of the programs covered general information, some provided specific symptom management. Peers were the most common tutor delivering the program material. The most common Barlow components included symptom management (n = 44; 43.1%), information about condition/treatment (n = 34; 33.3%), and coping (n = 33; 32.4%). The most common PRISMS components were information about condition and management (n = 85; 83.3%), training/rehearsal for psychological strategies (n = 52; 51.0%), and lifestyle advice and support (n = 52; 51.0%). The most common Lorig components were taking action (n = 62; 60.8%), resource utilization (n = 57; 55.9%), and self-tailoring (n = 55; 53.9%). Conclusion: Applying self-management concepts to complex conditions such as SCI is only in the earliest stages of development. Despite having studied the topic from a broad perspective, this review reflects an ongoing program of research that links to an initiative to continue refining and testing self-management interventions in SCI.

Describing the current state of post-rehabilitation health system surveillance in Ontario - an invited review

Context: Spinal cord injury (SCI) presents numerous physiological, psychosocial, and environmental complexities resulting in significant healthcare system resource demands. Objective: To describe the current health system surveillance mechanisms in Ontario, Canada and highlight gaps in health surveillance among adults with SCI across their lifespan. Methods: A review of administrative data sources capturing SCI-specific information took place via internet searching and networking among SCI rehabilitation and health services experts with emphasis on functionality, health service utilization, and quality of life data. Results: The review identified a distinct paucity of data elements specific to the health surveillance needs of individuals with SCI living in the community. The gaps identified are: (1) a lack of data usability; (2) inadequate linkage between available datasets; (3) inadequate/infrequent reporting of outcomes; (4) a lack of relevant content/patient-reported outcomes; and, (5) failure to incorporate additional data sources (e.g. Insurance datasets). Conclusion: Currently, SCI-specific health data is disproportionately weighted towards the first 3-6 months post injury with detailed data regarding pre-hospital care, acute management and rehabilitation, but little existing infrastructure supporting community-based health surveillance. Given this reality, the bolstering of meaningful community health surveillance of this population across the lifespan is needed. Addressing the identified gaps in health surveillance must inform the creation of a comprehensive community health dataset incorporating patient-reported outcome measures and enabling linkage with existing administrative and/or clinical databases. A future harmonized data surveillance strategy would, in turn, positively impact function, health services, resource utilization and health-related quality of life surveillance.

Development of Emotional Well-Being indicators to advance the quality of spinal cord injury rehabilitation: SCI-High Project

Context: Emotional Well-Being (EWB) post-spinal cord injury or disease (SCI/D) is a critical aspect of adjustment to disability. Advancing care and assuring equity in care delivery within this rehabilitation care domain is essential. Herein, we describe the selection of EWB structure, process and outcome indicators for adults with SCI/D in the first 18 months after rehabilitation admission. Methods: A pan-Canadian Working Group completed the following tasks: (1) defined the EWB construct; (2) conducted a systematic review of available outcomes and their psychometric properties; (3) constructed a Driver diagram summarizing available evidence associated with EWB; and, (4) prepared a process map. Facilitated meetings allowed selection and review of feedback following rapid-cycle evaluations of proposed structure, process and outcome indicators. Results: The structure indicator is the proportion of staff with appropriate education and training in EWB and access to experts and resources. The process indicator is the proportion of SCI/D patients who were screened for depression and anxiety symptoms at rehabilitation admission and rehabilitation discharge. The intermediary outcome is the proportion of SCI/D patients at risk for depression or anxiety at rehabilitation discharge based on screening symptom scores. The final outcomes are: (a) proportion of individuals at risk for depression or anxiety based on screening symptom scores; and (b) proportion of individuals who received referral for EWB services or intervention. Conclusion: The proposed indicators have a low administrative burden and will ensure feasibility of screening for depression and anxiety at important transition points for individuals with SCI/D. We anticipate that the current structures have inadequate resources for at-risk individuals identified during the screening process.

An examination of objective social disconnectedness and perceived social isolation among persons with spinal cord injury/dysfunction: a descriptive cross-sectional study

PURPOSE

To describe objective social disconnectedness and perceived social isolation post-spinal cord injury/dysfunction (SCI/D), and to examine associations among social disconnectedness and social isolation by sociodemographic and clinical characteristics.

MATERIALS AND METHODS

A telephone-based questionnaire was administered to 170 community dwelling individuals with a SCI/D. Social disconnectedness was measured by social network size, composition, and frequency of contact. Social isolation was measured using the revised three item UCLA Loneliness Scale.

RESULTS

Of the 170 participants, the majority were men (n = 136, 80%), had a traumatic injury (n = 149, 87.6%), and had incomplete tetraplegia (n = 58, 34%). The mean network size was 3.86 (SD = 2.0) of a maximum seven. The mean loneliness score for the sample was 4.93 (SD = 1.87). Factors associated with lower feelings of loneliness included being married, living with a higher proportion of network members, and being employed. Size of networks was not significantly associated with feelings of loneliness.

CONCLUSIONS

This study highlights the vulnerability for perceived social isolation among persons with SCI/D. The size of network does not seem to matter as much as the frequency and quality of social interactions. Findings reinforce the complexity of social disconnectedness and the importance in understanding the various indicators of social disconnectedness as they relate to social isolation. IMPLICATIONS FOR REHABILITATION Social relationships have been shown to be a vital component of optimal health and well-being. Individuals with a spinal cord injury/dysfunction are faced with a number of challenges in developing and maintaining social relationships and community participation. Rehabilitation professionals should encourage opportunities for social inclusion, employment and community participation to optimize health and well-being for this population.

Patient subjective assessment of urinary tract infection frequency and severity is associated with bladder management method in spinal cord injury

STUDY DESIGN

The Neurogenic Bladder Research Group (NBRG) registry is a multicenter prospective observational study. This manuscript is retrospective based on a cross-sectional survey.

OBJECTIVES

To assess patient subjective assessment of urinary tract infection (UTI) frequency and severity are associated with the degree of use of catheters or incontinence products.

SETTING

Multiple hospitals across the United States.

METHODS

Eligibility included: age > 18 years and acquired SCI. Over 1.5 years, 1479 eligible participants were enrolled. We excluded those with surgical reconstruction or diversion of the bladder. In total, 1282 participants were grouped by bladder management: (1) indwelling catheter (IDC), (2) clean intermittent catheterization (CIC), (3) external devices (pads/condom), and (4) volitional voiding (Void). UTI frequency was classified as 0, 1-3, 4-6, or > 6 over the prior year. UTI severity was determined by hospitalization for UTI in the prior year. Multivariate regression compared these factors across groups.

RESULTS

UTIs were least frequent in Void followed by pads/condom, CIC, and IDC (all p ≤ 0.001). UTI severity followed a similar pattern. Controlling for covariates, the adjusted odds of UTI frequency (Void = reference) were 2.28 (1.38-3.76) for pads/condom, 3.42 (2.25-5.18) for CIC, and 4.3 (2.59-6.70) for IDC (all p ≤ 0.001).

CONCLUSIONS

Patient subjective assessment of UTI frequency is highest with IDC, followed by CIC, pads/condom, and lowest with spontaneous voiding. The odds of hospitalization for UTI were three times higher for IDC than spontaneous voiding. UTI risk should be considered when counseling patients about bladder management options. These associations do not imply causation but warrant further investigation in a prospective manner.

Identifying and Classifying Quality of Life Tools for Assessing Neurogenic Bowel Dysfunction After Spinal Cord Injury

Objectives: To identify and classify tools for assessing the influence of neurogenic bowel dysfunction (NBD) on quality of life (QoL) after spinal cord injury (SCI). Methods: In this systematic review, MEDLINE/PubMed, CINAHL, and PsycInfo were searched to identify studies assessing the influence of NBD on QoL (or related construct) after SCI. Two independent reviewers screened titles and abstracts, and both reviewers classified tools as subjective or objective according to Dijkers' theoretical QoL framework. Results: Seventy-two studies were identified, and 35 studies met the inclusion criteria. Five objective measures assessed the influence of NBD on QoL, which were validated for use in SCI, but no measure was condition-specific to NBD. Eight measures were classified as subjective tools; two had an established reliability and validity for SCI while six had some psychometric evidence for use in the SCI population. Five subjective measures (NBD score, Burwood QoL Questionnaire, Impediments to Community Integration [ICI] Scale, SCI-QoL Bowel Management Difficulties, and Survey of Neurogenic Bowel Characteristics) were developed specifically for SCI. The NBD score showed sensitivity to the influence of NBD on QoL in experimental trials. Conclusion: Thirteen tools assessed the influence of NBD on QoL in SCI. Although not developed specifically for SCI, the Health Utility Index (HUI-III) was the only tool identified that provided data on "QoL as utility" on the impact of NBD. The validated NBD score was the only condition-specific tool to assess QoL as "subjective well-being." Further validation of existing tools could help to inform practice and policy related to resource allocation for bowel care post SCI.

Using path analysis to investigate the relationships between standardized instruments that measure health-related quality of life, capability wellbeing and subjective wellbeing: An application in the context of spinal cord injury

While economic evaluations typically embrace health maximization as the maximization objective using quality-adjusted life years, there is increasing interest in the measurement of capability wellbeing and subjective wellbeing (SWB) for informing policy decisions. The objective of this study was to investigate the relationships between health-related quality of life (HRQoL), capability wellbeing and SWB. Data were used from 364 individuals living with spinal cord injury (SCI) who previously completed a web-based, cross-sectional survey (March-June 2013). Regression analyses were used to study the impacts of secondary health conditions on HRQoL, capability wellbeing and SWB; subsequently, a path analysis was used to assess direct and mediated pathways. HRQoL was measured using the EQ-5D-5L and the Assessment of Quality of Life 8-dimension (AQoL-8D) questionnaire; capability wellbeing was assessed using the ICEpop CAPability measure for Adults (ICECAP-A), and SWB was based on a single life satisfaction item (0-10 rating scale). Mean scores were 0.492, 0.573, 0.761 and 6.319 for EQ-5D-5L, AQoL-8D, ICECAP-A and SWB, respectively. Beta coefficients from the regression analyses indicated that secondary health conditions had the greatest negative impact on individuals' HRQoL (β_AQoL-8D = -0.668, β_EQ-5D-5L = -0.542), followed by SWB (β_SWB = -0.481) and capability wellbeing (β_ICECAP-A = -0.477). Capability wellbeing mediated the effect of secondary health conditions on HRQoL and SWB. The indirect effect of secondary health conditions on SWB through HRQoL was not statistically significant when using EQ-5D-5L; indirect effects were found when using AQoL-8D, one through HRQoL only and one through both capability wellbeing and HRQoL. This study highlights the different impacts of secondary health conditions on HRQoL, capability and SWB in the context of SCI. While the greatest impact was observed on individuals' HRQoL, our results provide further evidence that capability wellbeing (here, the ICECAP-A) adds complementary information about outcomes that could be used in economic evaluation.

Quality of Life and Health Utility Scores Among Canadians Living With Traumatic Spinal Cord Injury - A National Cross-Sectional Study

STUDY DESIGN

National, multicenter, cross-sectional study.

OBJECTIVE

The goal of this study was to provide overall quality of life (QOL) and health utility (HU) values for patients with traumatic spinal cord injury (SCI) stratified by injury level and neurological status.

SUMMARY OF BACKGROUND DATA

Traumatic SCI is a leading cause of disability. Varying injury level and severity generate a spectrum of neurological dysfunction and reduction in long-term QOL.

METHODS

The Canadian SCI Community Survey was sent to Canadians living in the community after SCI. The impact of demographics, complications, and SCI classification on QOL was assessed using Analysis of variance, multiple linear regressions and ordinal logistic regression analyses.

RESULTS

There were 1109 respondents with traumatic SCI. american spinal injury association impairment scale (AIS) grade was reported to be cervical motor complete in 20%, cervical motor incomplete in 28%, thoracolumbar motor complete in 32%, thoracolumbar motor incomplete in 16%, and normal (any level) in 1%. Injury level or AIS grade had no impact on either HU or QOL. The physical component of health-related quality of life (HRQOL) was significantly affected by the neurological level, but not the social or mental components. With a mean health utility score of 0.64 ± 0.12, SCI patients living in the community reported having HRQOL similar to patients after total knee arthroplasty or lumbar spinal stenosis decompression.

CONCLUSION

QOL or HU measured by generic HRQOL outcome tools should not be used as outcomes to assess the effectiveness of interventions targeting neurological function in traumatic SCI. A disease-specific instrument that captures the nuances specific to spinal cord injury patients is required.

Stigma and self-management: an Interpretative Phenomenological Analysis of the impact of chronic recurrent urinary tract infections after spinal cord injury

Study design

Qualitative, phenomenological design.

Objectives

Neurogenic bladder dysfunction and urinary tract infection (UTI) are common secondary consequences to neurological damage to the spinal cord. This study sought to establish the impact of chronic, recurrent UTIs on people with spinal cord injury (SCI).

Setting

Community sample, United Kingdom.

Methods

Twelve participants with SCI, aged between 28 and 68 years, who had experienced at least three recurrent UTI events within the previous 12 months were recruited. Detailed qualitative information was obtained from semi-structured interviews, which lasted between 30 and 60 min. Interpretative Phenomenological Analysis was performed to explore the lived experience of UTIs.

Results

Interview findings identified a range of factors related to the experience of recurrent UTIs in people with SCI. These were classified into the following themes: (1) Symptom Management Precedence, (2) Stigma-Motivated Risk Management and (3) Exhaustive Exploration of Treatment Options. Participants discussed management of acute exacerbations. Distress arose from perceptions of UTIs as potentially stigmatizing and fear of relying on antibiotics. Arising from this fear, many participants sought alternative prevention and management strategies.

Conclusions

These results suggest that chronic recurrent UTIs act as major barriers to social participation, with adverse effects on quality of life of people with a neurogenic bladder after SCI. People with SCI would benefit from additional assessment of the impact of recurrent UTIs, so that healthcare professionals can address specific concerns, such as the psychosocial impact of urinary incontinence and stigmatizing views. Additional support to enhance self-management and facilitate social participation should be provided.

Novas perspectivas de fisioterapia respiratória em lesão medular - uma revisão sistemática

Resumo Objetivo: Descrever e analisar parâmetros e efeitos da estimulação elétrica de superfície na função muscular respiratória de pessoas com lesão medular, sobretudo durante a tosse. Métodos: Foi realizada uma revisão sistemática da literatura, com base no Preferred Reporting items for Systematic Reviews and Meta-Analyses. A busca foi realizada nas bases de dados PubMed, PEDro e LILACS, por meio dos seguintes descritores: “estimulação elétrica funcional”, “eletroestimulação, estimulação elétrica”, “tosse”, “higiene brônquica”, “quadriplegia”, “lesão medular espinhal”, “tetraplegia” e “sujeito com tetraplegia” - em espanhol, inglês e português, sem restrição quanto ao ano de publicação. Foram incluídos artigos com amostra de indivíduos com lesão medular assistidos por estimulação elétrica com desfecho relacionado ao sistema respiratório, e foram excluídos artigos com ensaios invasivos de estímulo a tosse. Resultados: Os 12 artigos incluídos revelam heterogeneidade nos protocolos de eletroestimulação da função expiratória, que podem incluir frequências de 30 a 50 Hz, com pulsos de 25 a 400 μs, aplicada por até oito eletrodos distribuídos pelos músculos expiratórios e acessórios. O tempo de aplicação também foi variável e a amplitude de corrente frequentemente estimada pela percepção do paciente, podendo chegar a valores superiores a 100mA. Conclusão: Apesar de não ser possível estabelecer parâmetros rigorosos de fisioterapia por meio da estimulação elétrica, pela escassez e qualidade de estudos que comparem sistematicamente parâmetros de estimulação em subgrupos, foram observadas alterações positivas nas variáveis de função muscular respiratória avaliadas, como o pico de fluxo expiratório e de tosse, em pessoas com lesão medular cervical e torácica.

Identifying and classifying quality of life tools for neurogenic bladder function after spinal cord injury: A systematic review

OBJECTIVE

To identify and classify quality of life (QoL) tools for assessing the influence of neurogenic bladder after spinal cord injury/disease (SCI).

DESIGN

Systematic Review Methods: Medline/Pubmed, CINAHL, and PsycInfo were searched using terms related to SCI, neurogenic bladder and QoL. Studies that assessed the influence neurogenic bladder on QoL (or related construct) in samples consisting of ≥50% individuals with SCI were included. Two independent reviewers screened titles and abstracts of 368 identified references; 118 full-text articles were assessed for eligibility, and 42 studies were included. Two reviewers independently classified outcomes as objective (societal viewpoint) or subjective (patient perspective) using a QoL framework.

RESULTS

Ten objective QoL measures were identified, with the Medical Outcomes Short Form (SF-36/SF-12) used most frequently. Fourteen subjective QoL measures were identified; 8 were specific to neurogenic bladder. Psychometric evidence for SCI-specific neurogenic bladder QoL tools was reported for the Quality of Life Index (QLI), Qualiveen, Bladder Complications Scale, Spinal Cord Injury-Quality of Life (SCI-QOL) Bladder Management Difficulties, and the SCI-QOL Bladder Management Difficulties-Short Form. The QLI and Qualiveen showed sensitivity to neurogenic bladder in experimental designs.

CONCLUSION

Several objective and subjective tools exist to assess the influence of neurogenic bladder on QoL in SCI. The QLI and Qualiveen, both subjective tools, were the only validated SCI-specific tools that showed sensitivity to neurogenic bladder. Further validation of existing subjective SCI-specific outcomes is needed. Research to validate objective measures of QoL would be useful for informing practice and policy related to resource allocation for bladder care post-SCI.

Evaluation of a specialized yoga program for persons with a spinal cord injury: a pilot randomized controlled trial

Objectives

The purpose of this randomized controlled trial was to evaluate the effects of a specialized yoga program for individuals with a spinal cord injury (SCI) on pain, psychological, and mindfulness variables.

Materials and methods

Participants with SCI (n=23) were outpatients or community members affiliated with a rehabilitation hospital. Participants were randomized to an Iyengar yoga (IY; n=11) group or to a 6-week wait-list control (WLC; n=12) group. The IY group participated in a twice-weekly 6-week seated IY program; the WLC group participated in the same yoga program, after the IY group’s yoga program had ended. Pain, psychological, and mindfulness measures were collected at two time points for both groups (within 1–2 weeks before and after program 1 and at a third time point for the WLC group (within 1 week after program 2).

Results

Linear mixed-effect growth models were conducted to evaluate the main effects of group at T2 (postintervention), controlling for T1 (preintervention) scores. T2 depression scores were lower (F_1,18=6.1, P<0.05) and T2 self-compassion scores higher (F_1,18=6.57, P< 0.05) in the IY group compared to the WLC group. To increase sample size and power, the two groups were combined and analyzed across time by comparing pre- and postintervention scores. Main effects of time were found for depression scores, (F_1,14.83=6.62, P<0.05), self-compassion, (F_1,16.6=4.49, P<0.05), mindfulness (F_1,16.79=5.42, P<0.05), mindful observing (F_1,19.82=5.06, P<0.05), and mindful nonreactivity, (F_1,16.53=4.92, P<0.05), all showing improvement after the intervention.

Discussion

The results indicated that a specialized 6-week yoga intervention reduced depressive symptoms and increased self-compassion in individuals with SCI, and may also have fostered greater mindfulness.

Outcomes and reflections on a consensus-building workshop for developing a spinal cord injury-related chronic pain research agenda

Context/ Objective: Chronic pain following spinal cord injury (SCI) is a prevalent secondary health condition that significantly impacts quality of life (QoL). Although growing, the number of available effective pain management approaches for SCI is limited. Recognizing the need to "kick-start" activity on this topic, a consensus-building workshop on developing a research agenda for SCI-related chronic pain was held in 2006 with an expert panel. The present paper describes the processes of the consensus-workshop and its associated outcomes towards advancing the research agenda for SCI-related pain in Canada. A commentary on the current state of knowledge regarding SCI-related pain is also provided.

METHODS

Thirty-nine stakeholders (researchers, clinicians, policy-makers, SCI advocates, and people with SCI) attended the consensus-workshop. A modified Delphi approach was employed to gain consensus on identifying the top five SCI pain research priorities for improving QoL post-SCI. As well, project planning along with infrastructure support opportunities were discussed.

RESULTS

The top five pain research priorities were: 1) pain management and treatment; 2) measurement tools; 3) health services policy and advocacy; 4) knowledge transfer; and 5) mechanisms of pain. Recommendations related to the priorities and related resources were generated, and pilot work was initiated.

CONCLUSIONS

The consensus workshop provided an initial roadmap for research on SCI-related chronic pain, and supported five pilot projects on the identified priorities. Reflections on the current research landscape in Canada and abroad suggest increased activity towards addressing pain post-SCI but evidence-based approaches are still lacking.

Vibration training after chronic spinal cord injury: Evidence for persistent segmental plasticity

H-reflex paired-pulse depression is gradually lost within the first year post-SCI, a process believed to reflect reorganization of segmental interneurons after the loss of normal descending (cortical) inhibition. This reorganization co-varies in time with the development of involuntary spasms and spasticity. The purpose of this study is to determine whether long-term vibration training may initiate the return of H-reflex paired-pulse depression in individuals with chronic, complete SCI. Five men with SCI received twice-weekly vibration training (30Hz, 0.6g) to one lower limb while seated in a wheelchair. The contra-lateral limb served as a within-subject control. Paired-pulse H-reflexes were obtained before, during, and after a session of vibration. Untrained limb H-reflex depression values were comparable to chronic SCI values from previous reports. In contrast, the trained limbs of all 5 participants showed depression values that were within the range of previously-reported Acute SCI and Non-SCI H-reflex depression. The average difference between limbs was 34.98% (p=0.016). This evidence for the return of H-reflex depression suggests that even for people with long-standing SCI, plasticity persists in segmental reflex pathways. The spinal networks involved with the clinical manifestation of spasticity may thus retain adaptive plasticity after long-term SCI. The results of this study indicate that vibration training may hold promise as an anti-spasticity rehabilitation intervention.

The development of an outcome measures toolkit for spinal cord injury rehabilitation

BACKGROUND

Spinal cord injury (SCI) is a complex medical condition that can be difficult to monitor.

PURPOSE

This study aimed to establish a common set of validated outcome measures specifically for SCI clinical practice.

METHOD

In a three-round online Delphi process, experts in SCI care across Canada suggested and ranked outcome measures for clinical practice. The facilitators provided feedback between rounds and determined if consensus (at least 75% agreement) was reached on a single outcome measure per clinical area.

FINDINGS

One hundred and forty-eight outcome measures were initially considered for inclusion. After three rounds, consensus was reached for 23 out of 30 clinical areas. In the remaining seven, more than one outcome measure was recommended. The final toolkit comprises 33 outcome measures with sufficient measurement properties for use with a SCI population.

IMPLICATIONS

An outcome measures toolkit validated specifically for SCI should lead to improved identification of best practice and enable clinicians to monitor client progress effectively.

Healthcare resource consumption for intermittent urinary catheterisation: cost-effectiveness of hydrophilic catheters and budget impact analyses

OBJECTIVES

This study presents a cost-effectiveness analysis comparing hydrophilic coated to uncoated catheters for patients performing urinary intermittent catheterisation. A national budget impact analysis is also included to evaluate the impact of intermittent catheterisation for management of bladder dysfunctions over a period of 5 years.

DESIGN

A Markov model (lifetime horizon, 1 year cycle length) was developed to project health outcomes (life years and quality-adjusted life years) and economic consequences related to patients using hydrophilic coated or uncoated catheters. The model was populated with catheter-related clinical efficacy data retrieved from randomised controlled trials and quality-of-life data (utility weights) from the literature. Cost data (EUR, 2015) were estimated on the basis of healthcare resource consumption derived from an e-survey addressed to key opinion leaders in the field.

SETTING

Italian Healthcare Service perspective.

POPULATION

Patients with spinal cord injury performing intermittent urinary catheterisation in the home setting.

MAIN OUTCOME MEASURES

Incremental cost-effectiveness and cost-utility ratios (ICER and ICUR) of hydrophilic coated versus uncoated catheters and associated healthcare budget impact.

RESULTS

The base-case ICER and ICUR associated with hydrophilic coated catheters were €20 761 and €24 405, respectively. This implies that hydrophilic coated catheters are likely to be cost-effective in comparison to uncoated ones, as proposed Italian threshold values range between €25 000 and €66 400. Considering a market share at year 5 of 89% hydrophilic catheters and 11% uncoated catheters, the additional cost for Italy is approximately €12 million in the next 5 years (current market share scenario for year 0: 80% hydrophilic catheters and 20% uncoated catheters).

CONCLUSIONS

Considered over a lifetime, hydrophilic coated catheters are potentially a cost-effective choice in comparison to uncoated ones. These findings can assist policymakers in evaluating intermittent catheterisation in patients with spinal cord injury.

Health state descriptions, valuations and individuals' capacity to walk: a comparative evaluation of preference-based instruments in the context of spinal cord injury

PURPOSE

This study explores variation in health state descriptions and valuations derived from preference-based health-related quality of life instruments in the context of spinal cord injury (SCI).

METHODS

Individuals living with SCI were invited to complete a web-based, cross-sectional survey. The survey comprised questions regarding demographics, SCI classifications and characteristics, secondary health complications and conditions, quality of life and SCI-specific functioning in activities of daily living. Four preference-based health status classification systems were included; Assessment of Quality of Life 8-dimension questionnaire (AQoL-8D), EQ-5D-5L, Health Utilities Index (HUI) and SF-6D (derived from the SF-36v2). In addition to descriptive comparisons of index scores and item/dimension responses, analyses explored dimension-level correlation and absolute agreement (intraclass correlation coefficient (ICC)). Subgroup analyses examined the influence of individuals' self-reported ability to walk.

RESULTS

Of 609 invitations, 364 (60 %) individuals completed the survey. Across instruments, convergent validity was seen between pain and mental health dimensions, while sizeable variation pertaining to issues of mobility was observed. Mean index scores were 0.248 (HUI-3), 0.492 (EQ-5D-5L), 0.573 (AQoL-8D) and 0.605 (SF-6D). Agreement ranged from 'slight' (HUI-3 and SF-6D; ICC = 0.124) to 'moderate' (AQoL-8D and SF-6D; ICC = 0.634). Walking status had a markedly different impact on health state valuations across instruments.

CONCLUSIONS

Variation in the way that individuals are able to describe their health state across instruments is not unique to SCI. Further research is necessary to understand the significant differences in index scores and, in particular, the implications of framing mobility-related questions in the context of respondents' ability to walk.

Identifying and classifying quality of life tools for assessing spasticity after spinal cord injury

OBJECTIVE

To identify and classify tools for assessing the influence of spasticity on quality of life (QOL) after spinal cord injury (SCI).

METHODS

Electronic databases (MEDLINE/PubMed CINAHL and PsycInfo) were searched for studies published between 1975 and 2012. Dijkers's theoretical framework on QOL was used to classify tools as either objective or subjective measures of QOL.

RESULTS

Sixteen studies met the inclusion criteria. Identified objective measures that were used to assess the influence of spasticity on QOL included the Short Form-36 (SF-36) the Sickness Impact Profile (SIP) and the Health Utilities Index-III (HUI-III). Subjective measures included the Quality of Life Index-SCI Version III (QLI-SCI) Life Situation Questionnaire-Revised (LSQ-R) Reciprocal Support Scale (RSS) Profile of Mood States (POMS) Spinal Cord Injury Spasticity Evaluation Tool (SCI-SET) and the Patient Reported Impact of Spasticity Measure (PRISM). A number of tools proved either to be insensitive to the presence of spasticity (QLI-SCI) or yielded mixed (SF-36) or weak (RSS LSQ-R) results. Tools that were sensitive to spasticity had limited psychometric data for use in the SCI population (HUI-III SIP POMS) although 2 were developed specifically for assessing spasticity on daily life post SCI (SCI-SET PRISM).

CONCLUSIONS

Two condition-specific subjective measures the SCI-SET and PRISM emerged as the most promising tools for the assessment of spasticity impact on QOL after SCI. Further research should focus on establishing the psychometric properties of these measures for use in the SCI population.Key words: outcome measurement quality of life spasticity spinal cord injury.

Predicting health preference in chronic spinal cord injury

CONTEXT/OBJECTIVE

Health preference values relate to a person's state of well-being, and is a single metric anchored at 0 (death) and 1 (perfect health). Health preference plays a key role in health economics and health policy, particularly in interpreting the results of cost-effectiveness studies, and supports the allocation of healthcare resources. The current study used elements of the International Classification of Functioning, Disability and Health (ICF) framework to predict health preference in persons with spinal cord injury (SCI).

METHODS

Data were collected by telephone survey on (1) demographics, (2) impairment (etiology, neurological level of injury, and ASIA impairment scale), (3) secondary health conditions (SHCs) using the SCI-Secondary Conditions Scale-Modified, (4) functional abilities using the Spinal Cord Independence Measure (SCIM), and (5) health preference using the Health Utilities Index-Mark III (HUI-Mark III) among adults with chronic SCI. Variables were categorized according to ICF headings and hierarchical regression analyses were used to predict HUI-Mark III scores.

RESULTS

Adults with chronic traumatic or non-traumatic SCI (N = 357) reported a mean health preference score of 0.27 (±0.27). In predicting health preference, our model accounted for 55.1% of the variance with "body functions and structure", and "activity and participation", significantly contributing to the model (P < 0.0001). In particular, older age, being employed, and having higher SCIM scores were positively associated with health preference. Conversely, a higher SHC impact score was associated with poorer health preference.

CONCLUSIONS

Variables representative of "activity and participation" largely influence health preference among persons with chronic SCI, which may be amenable to intervention. These findings could be applied to advocate for health promotion and employment support programs to maximize well-being in persons aging with chronic SCI in the community.
