Prevalence, causes, and risk profile of rehospitalizations in persons with spinal cord injury within the first 10 years after primary rehabilitation.

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: This study aims to identify the prevalence, causes, time pattern and risk profile of rehospitalizations in persons with spinal cord injury (SCI) within a 10-year period following primary rehabilitation and identify most common secondary health conditions (SHCs) and risk profile leading to rehospitalizations. SETTING: Specialized hospital and rehabilitation center for SCI in Switzerland. METHODS: A retrospective analysis was conducted on clinical data from persons with SCI, discharged from initial rehabilitation between January 1, 2010, and December 31, 2012, and followed up over a period of ten years post-discharge. Descriptive statistical methods were utilized to compute the rehospitalization prevalence and to identify the primary reasons. RESULTS: 225 participants were included, 70% were male (n = 179), and the mean age was 50 years (SD 19, Range 17-88). 54% were classified as having paraplegia (n = 122), and 77% incomplete injuries (n = 180). Over the 10-year observation period post-discharge, 120 were readmitted at least once, (prevalence 53%). In total, 66 persons (29%) were rehospitalized once or twice, while 54 persons (24%) were rehospitalized three or more times, with a maximum of 14 times. In the 10-year period, the most common SHCs leading to rehospitalization were infections (19%), pressure injuries (18%), and gastrointestinal problems (16%). During the study period, 57 persons (25%) passed away. CONCLUSIONS: Rehospitalization after primary rehabilitation is frequent and in the majority of the cases due to SHCs. The study findings are valuable for resource planning in healthcare and can guide the implementation of preventive measures to avoid SHCs.

Exploring lifestyle components and associated factors in newly injured individuals with spinal cord injury.

STUDY DESIGN: Cross-sectional analysis from the Inception Cohort of the Swiss Spinal Cord Injury Study (SwiSCI). OBJECTIVES: To describe five lifestyle components in newly injured individuals with spinal cord injury (SCI), explore co-occurrence of these components, and identify associated personal and clinical factors. SETTINGS: Initial rehabilitation stay following traumatic and non-traumatic SCI. METHODS: Lifestyle components including overweight/obesity, low diet score, physical inactivity, smoking, and alcohol consumption were used independently and to calculate a composite lifestyle score. Analyses were conducted using descriptive statistics, co-occurrence analysis, and multivariate logistic regression. RESULTS: We included 251 individuals, of whom 77.7% were male, 73.7% suffered from traumatic SCI, and 59.8% had paraplegia. The median age was 51 years (IQR 36-64). Approximately twelve weeks after the injury, more than two-thirds of the study population met the criteria for overweight/obesity, and consumed insufficient amounts of fruits and vegetables, and excessive amounts of meat. Alcohol was consumed by 85.3% of individuals, and 26.8% were current smokers. Almost all study participants met the physical activity guidelines (90 min of moderate to strenuous activity physical activity per week). One-quarter of study participants experienced the co-occurrence of overweight/obesity, low diet score and alcohol consumption. Female sex, younger age and higher education were associated with healthier lifestyle components. CONCLUSION: Despite methodological limitations, this study underscores the complexities of healthy lifestyle adherence among individuals newly injured with SCI. It highlights the necessity of improving and implementing screening strategies throughout the continuum of SCI care as early as possible following the trauma.

Does cardiometabolic risk profile differ among individuals with traumatic and non-traumatic spinal cord injury (SCI): the evidence from the multicenter SCI cohort in Switzerland (SwiSCI).

STUDY DESIGN: Longitudinal study. OBJECTIVE: To explore whether individuals with traumatic spinal cord injury (TSCI) and non-traumatic SCI (NTSCI) experience different trajectories in changes of cardiometabolic disease (CMD) factors during initial rehabilitation stay. SETTING: Multicenter Swiss Spinal Cord Injury Cohort (SwiSCI) study. METHODS: Individuals without history of cardiovascular diseases were included. CMD factors and Framingham risk score (FRS) were compared between TSCI and NTSCI. Linear mixed models' analysis was employed to explore the trajectory in CMD factors changes over rehabilitation period and a multivariate linear regression analysis was used at discharge from inpatient rehabilitation to explore factors associated with CMD risk profile in TSCI and NTSCI. We performed age and sex-stratified analyses. RESULTS: We analyzed 530 individuals with SCI (64% with TSCI and 36% NTSCI). The median age was 53 years (IQR:39-64) with 67.9% (n = 363) of the study cohort being male. The median rehabilitation duration was 4.4 months (IQR 2.4-6.4). At admission to rehabilitation, FRS (9.61 vs. 5.89) and prevalence of hypertension (33.16% vs. 13.62%), diabetes (13.68% vs. 4.06%), and obesity (79.05% vs. 66.67%) were higher in NTSCI as compared to TSCI, No difference was observed in cardiometabolic syndrome between the groups (around 40% in both groups). Overall, we observed longitudinal increases in total cholesterol, HDL-C and HDL/total cholesterol ratio, and a decrease in fasting glucose over the rehabilitation period. No differences in longitudinal changes in cardiovascular risk factors were observed between TSCI and NTSCI. CONCLUSIONS: There was no deterioration in cardiometabolic risk factors over rehabilitation period, at discharge from initial rehabilitation stay. Both TSCI and NTSCI experienced high burden of cardiometabolic syndrome components with NTSCI experiencing more disadvantageous risk profile. The effectiveness of therapeutic and lifestyle/behavioral strategies to decrease burden of cardiometabolic disease and its components in early phase should be explored in future studies.

The Swiss Spinal Cord Injury Cohort Study (SwiSCI) biobank: from concept to reality.

OBJECTIVES: To describe the concept, establishment and the operationalization of the biobank of the Swiss Spinal Cord Injury Cohort Study (SwiSCI), the available biosamples, and demographic and clinical characteristics of study participants. SETTING: The SwiSCI biobank is a platform for research within SwiSCI. It collects and processes serum, plasma, PBMCs, RNA, DNA, and urine from three rehabilitation centers. Samples are collected at admission to first rehabilitation and at discharge. Additionly, the biobank provides services to projects nested in SwiSCI or otherclinical trials among Spinal Cord Injury population. METHODS: Descriptive statistics were used for an overview of available biosamples, study participant characteristics, and comparison of the participating centers. RESULTS: Between the SwiSCI biobank establishment on June 27th, 2016, and October 19th, 2023, the SwiSCI Study has obtained informed consent from 524 individuals. Of these, 315 (60.1%) have agreed to donate biospecimens to the biobank. The average age of the contributors was 54 years (range: 38-65), with the majority being male (80%). Most participants suffered from traumatic injuries (66%) and were classified as paraplegic (64%). Approximately 80% presented with motor and sensory-incomplete SCI. The median Spinal Cord Independence Measure (SCIM) score was 31 (Interquartile Range: 19-58). The proportion of individuals providing paired biosamples at two distinct time points ranged from 63% (for RNA) to 65% (for urine and urine sediment). CONCLUSIONS: The SwiSCI biobank is a unique platform designed to serve as a basis for collaborative SCI research, including multi-omics approaches. The longitudinal collection of biospecimens and cryopreservation of multiple aliquots for each participant are fundamental for scrutinizing the temporal associations, ensuring research reproducibility, and achieving an adequate sample size for future investigations.

Unplanned hospital admissions due to secondary health conditions after spinal cord injury: a population-based description of determinants of length of stay.

STUDY DESIGN: Population-based prospective study. OBJECTIVES: To provide a population-based description of length of stay (LOS) and person-related risk factors following unplanned hospital admission due to a secondary health condition (SHC) in persons with spinal cord injury (SCI). SETTING: Specialized SCI hospital and rehabilitation center in Switzerland. METHODS: Descriptive analysis of LOS using routine clinical data of persons with SCI, who were acutely hospitalized between 01.01.2017-30.06.2018. Multivariable regression analysis was used to derive marginal predictions of LOS by acute SHCs and person characteristics. RESULTS: The study included 183 persons, 83% were male, and the median age was 57 years (interquartile range, IQR, 49-67 years). SCI cause was traumatic in 160 (88.4%) cases, 92 (50.3%) were persons with tetraplegia, 147 (80.3%) were classified as motor complete lesions (American Spinal Injury Association Impairment Scale (AIS) A or B) and median time since injury (TSI) was 24 (IQR 13-34) years. Median LOS was 19 (IQR 9-39) days, varying from 74 (IQR 39-92) days for pressure ulcers, 13 (IQR 8-24) days for urinary tract infections (UTI), to 27 (IQR 18-47) days for fractures. LOS was prolonged in persons with multiple co-morbidities or those developing complications during hospitalization. Sex, SCI etiology and lesion level were not associated with LOS. CONCLUSIONS: This population-based description identified substantial variation in LOS between acute SHCs and clinical complications as the main, potentially modifiable, person-related risk factors for extended hospital stay.

Who is at Risk of Loneliness? A Cross-sectional Recursive Partitioning Approach in a Population-based Cohort of Persons With Spinal Cord Injury.

OBJECTIVE: To develop a more thorough understanding of the risk factors for loneliness in persons with a physical impairment, using a population-based sample of persons with spinal cord injury (SCI), based on regression modeling and a recursive partitioning approach. DESIGN: Cross-sectional, observational cohort. SETTING: Community, Switzerland. PARTICIPANTS: Community-dwelling persons with spinal cord injury (N=1283) 16 years or older. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Loneliness was assessed using a modified version of the UCLA Three-Item Loneliness Scale. RESULTS: Those with the most disadvantaged socioeconomic characteristics in terms of education, income, subjective social position, employment status, and financial hardship demonstrated the highest risk for loneliness. Of the sociodemographic characteristics, only age had an association with loneliness, whereby persons aged 31-45 had the highest propensity for experiencing loneliness. We also saw that those with higher lesion levels and less functional independence were associated with higher levels of loneliness. In conditional inference tree analysis subjective social position, financial hardship, and functional independence had the highest discriminative power, with nationality and living arrangement having a less important role. CONCLUSIONS: Our findings highlight the vulnerability of persons with SCI with unfavorable socioeconomic status to loneliness. Furthermore, our findings show that persons who are more constrained because of functional limitations may face restrictions to social participation and therefore be at a higher risk of loneliness. This population-based evidence contributes to the better targeting of services aimed at alleviating loneliness for persons with a lower socioeconomic position and those with more functional limitations in everyday life.

Pathways to loneliness: a mediation analysis investigating the social gradient of loneliness in persons with disabilities in Switzerland.

BACKGROUND: The experience of loneliness can have drastic consequences for health and quality of life. Given that loneliness is highly prevalent in persons with physical disabilities and that loneliness more profoundly affects persons of low socioeconomic status, more evidence is required in order to understand the mechanisms determining loneliness in this population. The objective of this study is therefore to investigate the potential pathways through which socioeconomic status influences loneliness in persons with spinal cord injury. METHODS: Mediation analysis utilising structural equation models and bias corrected and accelerated confidence intervals were used in order to test the mediation effects of health status, functioning, participation, social support and self-efficacy on the association between socioeconomic status and loneliness in persons with spinal cord injury. A latent construct was created for socioeconomic status with the indicators education, household income, financial hardship, subjective social status and engagement in paid work. RESULTS: This study found evidence to support the mediating role of psychosocial resources and of secondary health conditions in the association between socioeconomic status and loneliness. The study demonstrated robust associations between socioeconomic status and all potential mediators, whereby higher socioeconomic status was associated with better health, participation and psychosocial resources, however, not all potential mediators were associated with loneliness. The serial mediation model explained the interplay between socioeconomic status, mediators on different levels, and loneliness. For example, emotional support and self-efficacy were both positively associated with fewer restrictions to participation (0.08 (CI: 0.05, 0.12); 0.29 (CI: 0.24, 0.36) respectively), and fewer restrictions to participation were found to be a result of improved functional independence and fewer secondary health conditions (0.23 (CI: 0.15, 0.39); - 0.29 (CI: - 0.36, - 0.20) respectively). CONCLUSIONS: Our findings highlight the vulnerability of persons with low socioeconomic status to loneliness in persons with spinal cord injury and identified potential mediating factors, such as health, functioning, participation and psychosocial resources, in the association between socioeconomic status and loneliness. This population-based evidence suggests potential targets of interventions on the pathway to loneliness, through which socioeconomic status influences loneliness. The complexity of the model shows the need for comprehensive interprofessional rehabilitation to identify and support people with lower socioeconomic status and concomitant risk factors for loneliness.

Utilization of health care providers by individuals with chronic spinal cord injury.

STUDY DESIGN: Questionnaire survey conducted in 2017 as part of the Swiss Spinal Cord Injury Cohort Study (SwiSCI). OBJECTIVES: To elucidate the use of outpatient health care providers by individuals with chronic spinal cord injury in a situation of free choice and ample supply. SETTING: Community, nationwide. METHODS: The frequency of visits was compared to that of a survey conducted five years earlier. Using regression tree analysis, the characteristics of individuals with extensive use of health care providers' services were investigated. Substitution effects, where health care users replace one provider type by another, were quantified using likelihood ratios for positive outcomes. RESULTS: The questionnaire was returned by 1,294 persons (response rate 33%). Participants reported visits to 14 different health care providers within the previous 12 months. Most often visited was the general practitioner (GP) by 82%. Older individuals used fewer health care providers than younger participants. Individuals with spasticity and females visited a broader variety of health care providers than the average user. The participants used fewer providers than they did five years ago. Health care users were not found to be substituting one provider type with another. CONCLUSIONS: Individuals with spinal cord injury in Switzerland use a wide array of medical service providers. All providers were used complementary to each other without redundancies between providers. The use of providers is driven by health-related factors and gender. Old age was not as much a driver for high utilization as described in other settings.

Factors influencing specialized health care utilization by individuals with spinal cord injury: a cross-sectional survey.

STUDY DESIGN: Cross-sectional observational study using data from the second community survey of the Swiss Spinal Cord Injury Cohort Study (Survey 2017) conducted between 03/2017 and 03/2018. OBJECTIVES: To identify facilitators of and barriers to utilizing SCI-specialized outpatient clinic and inpatient care by individuals with spinal cord injury (SCI). SETTING: Community. METHODS: Multivariable logistic regression was used to identify factors influencing (1) the attendance at annual check-ups at SCI-specialized treatment facilities, (2) the utilization of SCI-specialized outpatient clinic care by those who utilized any outpatient clinic care, and (3) the utilization of SCI-specialized inpatient care by those who were hospitalized. Multiple imputation was used to account for missing data. RESULTS: Out of 3959 eligible individuals, 1294 completed the questionnaire (response rate 33%). In the last 12 months, 51% of study participants attended the annual check-up, 33% of outpatient clinic care users utilized SCI-specialized outpatient clinic care, and 44% of those who were hospitalized were hospitalized at a SCI center. Annual check-ups were attended less by women, the elderly, and those with nontraumatic SCI. SCI-specialized outpatient clinic care was less likely to be utilized when individuals with SCI were living with cancer, lived farther away from SCI-specialized treatment facilities or in a minority language region. Specialized inpatient care was less likely to be utilized by women and those with incomplete lesions. CONCLUSIONS: SCI-specialized outpatient clinic care must be provided near the residence of individuals with SCI, otherwise non-specialized care is utilized. The reasons why women utilize SCI-specialized care less frequently than men merits further investigation.

Etiology-specific variation in survival following non-traumatic spinal cord injury: a causal inference approach using data from a population-based cohort.

STUDY DESIGN: Observational, population-based cohort study. OBJECTIVES: To evaluate the origin and contribution to excess of survival differences following non-traumatic spinal cord injury (NTSCI) using etiology as proxy for variation in underlying health condition. SETTING: Specialized rehabilitation centers in Switzerland. METHODS: Medical record data collected by the Swiss Spinal Cord Injury cohort (SwiSCI) study were linked with mortality information from the Swiss National Cohort. Considering contemporary theory and empirical evidence, a directed acyclic graph (DAG) was developed to formally evaluate causal differences among NTSCI etiologies, relative to traumatic SCI (TSCI). Statistical inference was contingent on hazard ratios (HRs) and marginal survival differences, derived using flexible parametric modeling. RESULTS: 3643 individuals (NTSCI = 1357; TSCI = 2286) diagnosed with SCI between 1990 and 2011 were included, contributing a cumulative 41,344 person-years and 1323 deaths. Test statistics confirmed DAG-dataset consistency. As compared to TSCI, mortality was elevated in all NTSCI etiological groups; malignant etiologies had the highest HRs (10; 95% CI, 8.0 to 14) followed by infection (2.6; 1.8 to 3.6) and vascular (2.5; 2.0 to 3.2) etiology groups. At the attained age of 55, the estimated reduction in survival among non-malignant etiologies was 9.4% (5.8 to 13) at 5 years and 17% (11 to 23) at 20 years. CONCLUSIONS: Causal differences in survival among NTSCI etiological groups are likely a result of chronic variation in health conditions. This study supports the development of long-term interdisciplinary management and policy for individuals with NTSCI, specific to etiology.

Self-reports of treatment for secondary health conditions: results from a longitudinal community survey in spinal cord injury.

STUDY DESIGN: Longitudinal community survey. OBJECTIVES: To describe the treatment for secondary health conditions as reported by individuals living with spinal cord injury (SCI) and to identify potential predictors of treatment. SETTING: Community (people with SCI living in Switzerland). METHODS: Data on the frequency, severity, and treatment of 14 common health conditions (HCs) in the past three months were collected in two surveys by the Swiss Spinal Cord Injury (SwiSCI) cohort study, in 2012 and 2017. Variation in treatment was analyzed using descriptive statistics, by survey period and severity of HC. Conditional multilevel random-effects logistic regression was used to describe differences in self-reported treatment with respect to sociodemographic and socioeconomic factors in addition to SCI characteristics and severity and number of HCs. RESULTS: Severe or chronic autonomic dysreflexia and sleep problems showed in the self-report as the HCs with the lowest occurrence/frequency of treatment. Across all HCs, higher age, shorter time since injury, the total number of HCs, and level of severity were associated with a higher propensity for reporting treatment. Individuals with severe financial difficulties additionally had 1.40 greater odds of receiving treatment (95% CI 1.09-1.80). CONCLUSIONS: This study identified systematic differences in the report of HCs and their treatment within the Swiss SCI community. This study thus provides a basis to guide future research on identifying targets of intervention for long-term clinical management of SCI.

First contact of care for persons with spinal cord injury: a general practitioner or a spinal cord injury specialist?

BACKGROUND: Although general practitioners (GPs) are generally considered as the first point of contact for care, this may be different for persons with complex conditions, such as those with spinal cord injury (SCI). The objective of this study is to understand the differences in long-term care provision by GPs and SCI-specialists, by examining (1) the first contact of care for SCI health problems, (2) the morbidity profile and use of health-care services in relation to first contact, and (3) the factors associated with the choice of first contact. METHODS: In this cross-sectional study based on data derived from the Swiss Spinal Cord Injury Cohort Study Community Survey 2017, the main outcome measure was the reported first contact for SCI-specific care. This information was analysed using the chi-square test and logistic regression analysis of groups based on patient characteristics, use of health-care services and secondary health conditions assessed using the Spinal Cord Injury Secondary Conditions Scale (SCI-SCS). RESULTS: Out of 1294 respondents, 1095 reported their first contact for SCI-specific care; 56% indicated SCI-specialists and 44% specified GPs. On average, participants who first contacted a GP reported higher number of GP consultations (5.1 ± 5.2 vs. 3.9 ± 7.2), planned visits to ambulatory clinics (3.7 ± 7.3 vs. 3.6 ± 6.7) and hospital admissions (GP, 1.9 ± 1.7 vs. 1.5 ± 1.3), but lower number of visits to SCI-specialists (1.7 ± 1.8 vs. 2.6 ± 1.7) and of hospital days (22.8 ± 43.2 vs. 31.0 ± 42.8). The likelihood to contact a GP first was significantly higher in persons ≥75 years old (OR = 4.44, 95% CI = 1.85-10.69), Italian speakers (OR = 5.06, 95% CI = 2.44-10.47), had incomplete lesions (OR = 2.39, 95% CI = 1.71-3.35), experiencing pain (OR = 1.47, 95% CI = 1.04-2.09) or diabetes mellitus (OR = 1.85, 95% CI = 1.05-3.27), but lower for those situated closer to SCI centres (OR = 0.69, 95% CI = 0.51-0.93) or had higher SCI-SCS scores (OR = 0.92, 95% CI = 0.86-0.99). CONCLUSION: Age, language region, travel distance to SCI centres, lesion completeness, and occurrence of secondary conditions play a significant role in determining the choice of first contact of care, however there is still some unwarranted variation that remains unclear and requires further research.

Changes in supraspinatus and biceps tendon thickness: influence of fatiguing propulsion in wheelchair users with spinal cord injury.

STUDY DESIGN: A quasi-experimental, pretest-posttest design. OBJECTIVES: To identify acute changes in the supraspinatus and biceps tendon following fatiguing wheelchair propulsion and to associate tendon changes with risk factors associated with shoulder pain in persons with spinal cord injury (SCI). SETTING: Biomechanical laboratory Swiss Paraplegic Research. METHODS: A population-based sample of 50 wheelchair users with SCI at lesion level T2 or below participated. Fatigue was measured by using the rate of perceived exertion and heart rate. Linear regression techniques were used to assess the association between the dependent and independent variables. Dependent variables included absolute differences in supraspinatus and biceps tendon thickness, contrast, and echogenicity ratio assessed with ultrasound before and after a fatiguing wheelchair propulsion intervention. Independent variables included susceptibility to fatigue (Yes/No), the acromio-humeral distance, sex, time since injury, activity levels, and body weight. RESULTS: A reduction in supraspinatus tendon thickness after fatiguing wheelchair propulsion (-1.39 mm; 95% CI: -2.28; -0.51) was identified after controlling for all potential confounders. Females who fatigued (n = 4) displayed a greater reduction in supraspinatus tendon thickness as compared with those who did not fatigue (n = 7). In contrast, higher body weight was associated with an increase in supraspinatus tendon thickness and a greater acromio-humeral distance before the intervention was associated with an increase in biceps tendon thickness. CONCLUSIONS: Acute changes in the supraspinatus and biceps tendon after fatiguing wheelchair propulsion may explain the high prevalence of tendon injuries in this population. Future research should determine the consequences of tendon changes and its relationship to tendinopathy.

Association of Shoulder Problems in Persons With Spinal Cord Injury at Discharge From Inpatient Rehabilitation With Activities and Participation 5 Years Later.

OBJECTIVE: To examine whether musculoskeletal shoulder pain and limitations in shoulder range of motion (ROM) at discharge from first rehabilitation are associated with activities and participation restrictions 5 years later in persons with spinal cord injury (SCI). DESIGN: Prospective cohort study. SETTING: Eight specialized SCI rehabilitation centers. PARTICIPANTS: Subjects (N=138) with an SCI admitted for first rehabilitation. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Peak power output (POpeak), Wheelchair Skills Test (WST), FIM motor score, ability to transfer, Physical Activity Scale for Individuals with Physical Disabilities (PASIPD), mobility range and social behavior subscales of the Sickness Impact Profile 68 (SIPSOC), and employment status. RESULTS: Mean age of the subjects at discharge was 39 years, 72% were men, 32% had tetraplegia, and in 65% the SCI was motor complete. At discharge, 39% reported shoulder pain and 32% had a limited shoulder ROM. In the analyses of variance, shoulder ROM limitation, but not shoulder pain, was associated with all but 1 outcome at 5 years. In the regression analyses, ROM limitations of the shoulder were negatively associated with the ability to transfer (P=.004), FIM motor scores (P<.001), and return to work (P= .027) 5 years after discharge. No significant associations were found with POpeak, WST performance time, SIPSOC, and PASIPD. CONCLUSIONS: The presence of limitations in shoulder ROM, but not shoulder pain, at discharge is associated with limitations in activities and employment status 5 years later.

International Retrospective Comparison of Inpatient Rehabilitation for Patients With Spinal Cord Dysfunction: Differences According to Etiology.

OBJECTIVES: To describe and compare epidemiologic characteristics and clinical outcomes of patients with nontraumatic spinal cord dysfunction according to etiology. DESIGN: Retrospective, multicenter open-cohort case series. SETTING: Spinal rehabilitation units (SRUs) in 9 countries. PARTICIPANTS: Patients (N=956; men, 60.8%; median age, 59.0y [interquartile range, 46-70.0y]; paraplegia, n=691 [72.3%]) with initial onset of spinal cord dysfunction consecutively admitted between January 1, 2008, and December 31, 2010. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Etiology of spinal cord dysfunction, demographic characteristics, length of stay (LOS) in rehabilitation, pattern of spinal cord dysfunction onset, discharge destination, level of spinal cord damage, and the American Spinal Injury Association Impairment Scale (AIS) grade on admission and discharge. RESULTS: The most common etiologies were degenerative (30.8%), malignant tumors (16.2%), infections (12.8%), ischemia (10.9%), benign tumors (8.7%), other vascular (8.5%), and other conditions (12.1%). There were major differences in epidemiologic characteristics and clinical outcomes of patients with different etiologies of spinal cord dysfunction. Paraplegia was more common in patients with a malignant tumor and vascular etiologies, while tetraplegia was more common in those with a degenerative etiology, a benign tumor, and infections. Patients with a malignant tumor tended to have the shortest LOS in the SRU, while those with a vascular etiology tended to have the longest. Except for patients with a malignant tumor, all patient groups had a significant change in their AIS grade between admission and discharge. CONCLUSIONS: This international study of spinal cord dysfunction showed substantial variation between the different etiologies regarding demographic and clinical characteristics, including changes in AIS between admission and discharge.

International retrospective comparison of inpatient rehabilitation for patients with spinal cord dysfunction epidemiology and clinical outcomes.

OBJECTIVE: To describe and compare epidemiologic characteristics of patients with spinal cord dysfunction admitted to spinal rehabilitation units (SRUs) in 9 countries (Australia, Canada, Italy, India, Ireland, The Netherlands, Switzerland, United Kingdom, and United States). DESIGN: Retrospective multicenter open-cohort case series. SETTING: SRUs. PARTICIPANTS: Patients (N=956) with initial onset of spinal cord dysfunction consecutively admitted between January 1, 2008, and December 31, 2010. Median age on admission was 59 years (interquartile range [IQR], 46-70), and 60.8% of patients were men. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Demographic characteristics (eg, age, sex), time frame over which clinical symptoms of spinal cord dysfunction developed, etiology, length of stay in hospital, level of lesion and American Spinal Injury Association Impairment Scale (AIS) grade, discharge destination, and inpatient mortality. RESULTS: The time frame of onset of spinal cord dysfunction symptoms was as follows: ≤1 day (28.5%); ≤1 week (13.8%); >1 week but ≤1 month (10.5%), and >1 month (47.2%). Most common etiologies were degenerative conditions (30.8%), malignant tumors (16.2%), ischemia (10.9%), benign tumors (8.7%), and bacterial infections (7.1%). Most patients (72.3%) had paraplegia. The AIS grade on SRU admission was grade A in 14%, grade B in 6.5%, grade C in 24%, grade D in 52.4%, grade E in 0.2%, and missing in 2.9%. AIS grade significantly improved by discharge (z=-10.1, P<.0001). Median length of stay in the SRU was 46.5 days (IQR, 17-89.5). Most (80.5%) patients were discharged home. Differences between countries were found for most variables. CONCLUSIONS: This international study of spinal cord dysfunction showed substantial variation of etiology, demographic, and clinical characteristics across countries. Further research, including multiple centers per country, are needed to separate country effects from center effects.

Non-pharmacological interventions for chronic pain in people with spinal cord injury.

BACKGROUND: Chronic pain is frequent in persons living with spinal cord injury (SCI). Conventionally, the pain is treated pharmacologically, yet long-term pain medication is often refractory and associated with side effects. Non-pharmacological interventions are frequently advocated, although the benefit and harm profiles of these treatments are not well established, in part because of methodological weaknesses of available studies. OBJECTIVES: To critically appraise and synthesise available research evidence on the effects of non-pharmacological interventions for the treatment of chronic neuropathic and nociceptive pain in people living with SCI. SEARCH METHODS: The search was run on the 1st March 2011. We searched the Cochrane Injuries Group's Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (OvidSP), Embase (OvidSP), PsycINFO (OvidSP), four other databases and clinical trials registers. In addition, we manually searched the proceedings of three major scientific conferences on SCI. We updated this search in November 2014 but these results have not yet been incorporated. SELECTION CRITERIA: Randomised controlled trials of any intervention not involving intake of medication or other active substances to treat chronic pain in people with SCI. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed risk of bias in the included studies. The primary outcome was any measure of pain intensity or pain relief. Secondary outcomes included adverse events, anxiety, depression and quality of life. When possible, meta-analyses were performed to calculate standardised mean differences for each type of intervention. MAIN RESULTS: We identified 16 trials involving a total of 616 participants. Eight different types of interventions were studied. Eight trials investigated the effects of electrical brain stimulation (transcranial direct current stimulation (tDCS) and cranial electrotherapy stimulation (CES); five trials) or repetitive transcranial magnetic stimulation (rTMS; three trials). Interventions in the remaining studies included exercise programmes (three trials); acupuncture (two trials); self-hypnosis (one trial); transcutaneous electrical nerve stimulation (TENS) (one trial); and a cognitive behavioural programme (one trial). None of the included trials were considered to have low overall risk of bias. Twelve studies had high overall risk of bias, and in four studies risk of bias was unclear. The overall quality of the included studies was weak. Their validity was impaired by methodological weaknesses such as inappropriate choice of control groups. An additional search in November 2014 identified more recent studies that will be included in an update of this review.For tDCS the pooled mean difference between intervention and control groups in pain scores on an 11-point visual analogue scale (VAS) (0-10) was a reduction of -1.90 units (95% confidence interval (CI) -3.48 to -0.33; P value 0.02) in the short term and of -1.87 (95% CI -3.30 to -0.45; P value 0.01) in the mid term. Exercise programmes led to mean reductions in chronic shoulder pain of -1.9 score points for the Short Form (SF)-36 item for pain experience (95% CI -3.4 to -0.4; P value 0.01) and -2.8 pain VAS units (95% CI -3.77 to -1.83; P value < 0.00001); this represented the largest observed treatment effects in the included studies. Trials using rTMS, CES, acupuncture, self-hypnosis, TENS or a cognitive behavioural programme provided no evidence that these interventions reduce chronic pain. Ten trials examined study endpoints other than pain, including anxiety, depression and quality of life, but available data were too scarce for firm conclusions to be drawn. In four trials no side effects were reported with study interventions. Five trials reported transient mild side effects. Overall, a paucity of evidence was found on any serious or long-lasting side effects of the interventions. AUTHORS' CONCLUSIONS: Evidence is insufficient to suggest that non-pharmacological treatments are effective in reducing chronic pain in people living with SCI. The benefits and harms of commonly used non-pharmacological pain treatments should be investigated in randomised controlled trials with adequate sample size and study methodology.

Utilization and features of rehabilitation and health services for persons with spinal cord injury.

BACKGROUND: The increasing prevalence of individuals experiencing disabilities underscores the importance of rehabilitation. Nevertheless, healthcare systems are already facing financial constraints, which makes it imperative to strive for a more efficient delivery of services. The first step, however, is to understand how the provision of services behaves for patients with different characteristics. AIM: To determine the most frequently used healthcare services in the (sub)acute phase of rehabilitation of patients with spinal cord injury/disease (SCI/D) and the link with patient characteristics. DESIGN: Observational cohort study. POPULATION: This study analyzes the clinical data of patients discharged from a specialized SCI hospital and rehabilitation center in Switzerland. METHODS: We implemented a compound risk model to estimate the total amount of healthcare services used, defined by length of stay (LOS) and the units per day of health services (sub)acute phase of rehabilitation. RESULTS: The study included 403 individuals with SCI/D. The analysis of the intensity and severity of healthcare services across different patient and injury characteristics revealed differences in the intensity of healthcare use and variations in the length of stay (LOS). Male patients with a low SCIM upon admission tended to use healthcare services more extensively than female patients. In terms of etiology, therapies were employed more intensively for patients with traumatic SCI (TSCI). In addition, the analysis revealed that variations in the intensity of healthcare services used were more significant than those adjusted for LOS. Ultimately, similar patient groups received comparable quantities of healthcare services at the end of treatment. CONCLUSIONS: This population-based study provides information for a better understanding of the determinants of health service use during the (sub)acute rehabilitation phase of individuals with SCI/D. When analyzing LOS, intensity, and severity of services, it shows that the use of healthcare services significantly differs for the level of SCIM at admission, age groups, sex, and etiology. However, the variation among individual patients also suggests the presence of other influential modifiers that were not considered in this analysis. CLINICAL REHABILITATION IMPACT: The approach outlined enables a systematic follow-up of this data analysis by enriching the computed data with additional details about the patient, the patient's treatment, and outcomes.

Non-adherence to follow-up care in persons with spinal cord injury within 10 years after initial rehabilitation.

OBJECTIVE: This study aimed to describe the temporal dynamics of and risk factors for non-adherence to outpatient follow-up care in the first 10 years after spinal cord injury. DESIGN: Retrospective single-centre cohort study using data from medical records and municipal resident registers. SUBJECTS/PATIENTS: Patients admitted to a specialized spinal cord injury centre in Switzerland discharged between 1 January 2010 and 31 December 2012 (n = 225). Time-to-event analysis was used to investigate the timing of the first non-adherence event, its association with spinal cord injury, and sociodemographic characteristics. RESULTS: 36% of patients were adherent to annual follow-up appointments; 2% formally transferred to another SCI centre; 44% were non-adherent for general reasons (patient's will to discontinue care [12%] or unknown reasons [32%]); and 18% were non-adherent due to death. Risk factors for non-adherence included older age, lack of long-term partner, and more than 2 h of travel time to the clinic. In the youngest age group (18-30 years), 55% were non-adherent after 10 years. CONCLUSION: A relevant proportion of individuals with spinal cord injury were lost to annual follow-up care. A holistic approach to patient engagement integrating solutions such as telemedicine and involvement of support networks could reduce the risk of non-adherence.

Health status, functioning and risk profiles for secondary health conditions in adolescents and young adults with spina bifida: a cross-sectional study at time of transition.

INTRODUCTION: The transition from paediatric to adult medical care is a critical period for adolescents with spina bifida, often marked by deteriorating health and functional status. OBJECTIVES: To describe the health status and functioning of individuals with spina bifida at the time of transition from paediatric to adult care and to identify risk profiles for potentially modifiable secondary health conditions (urinary tract infections, pressure injuries, respiratory problems and obesity). METHODS: Descriptive study of data (derived from medical records) from all adolescents and young adults with spina bifida aged 15-25 years who were referred to a single specialised spinal cord injury centre as part of the transition programme during the period from 1 September 2015 to 31 May 2022. Descriptive statistics were used to describe the study population and to analyse the frequency and co-occurrence of congenital and acquired secondary health conditions. The equality of proportions test was used to test the prevalence of secondary health conditions based on important personal and clinical characteristics. RESULTS: We included 43 adolescents with spina bifida with a mean age of 18.4 years (SD 2.5); in 63% of them the neurological level was lumbar, and around 50% of them were wheelchair-dependent. The median Spinal Cord Injury Measure (SCIM) III score was 72 (IQR 61-89). The mean number of secondary health conditions at time of transition was 8.8. The most prevalent secondary health conditions were lower urinary tract dysfunction, bowel dysfunction, sexual dysfunction and contractures. Respiratory problems were more prevalent in females and in individuals with lower SCIM III scores, whereas no differences were observed in the prevalence of other modifiable secondary health conditions. Clustering of secondary health conditions was mainly seen for urinary tract infection + pressure injury and for urinary tract infection + pressure injury + obesity. CONCLUSION: The prevalence of secondary health conditions among individuals with spina bifida at time of transition is alarmingly high and functional profiles underscore the need for supporting adolescents and young adults with daily medical issues. The study highlights the critical role of transition programmes and interdisciplinary follow-up care in preventing health problems and improving functioning and independence in everyday life.
