International spinal cord injury socio-demographic basic data set (version 1.0)

STUDY DESIGN

Consensus based on the literature.

OBJECTIVE

Create an International Spinal Cord Injury (SCI) Socio-Demographic Basic Data Set (Version 1.0).

SETTING

International.

METHODS

The development included an iterative process where the authors reviewed existing variables containing socio-demographic variables and created a first dataset draft, which was followed by several revisions through email communications. In addition, the work was conducted in parallel with a similar endeavour within the National Institute of Neurological Disorders and Stroke SCI Common Data Elements project in the United States. Subsequently, harmonization between the two projects was sought. Following this, a review process was initiated, including The International SCI Data Sets Committee, the American Spinal Injury Association (ASIA) Board, and the International Spinal Cord Society (ISCoS) Scientific and Executive Committees, and then by publishing on the respective websites for membership feedback. The draft was sent to about 40 national and international organizations and several interested individuals for feedback. All review comments were discussed in the working group and responded to before the final draft was developed, and finally approved by ASIA Board and the ISCoS Scientific and Executive committees.

RESULTS

The final International SCI Socio-Demographic Basic Data Set includes the following variables: Date of data collection, Marital status, Household member count, Years of formal education, and Primary occupation.

CONCLUSION

The International SCI Socio-Demographic Basic Data Set will facilitate uniform data collection and reporting of socio-demographic information at the time of injury as well as at post-injury follow-ups to facilitate the evaluation and comparisons across studies.

Differences in Societal Participation Across Diagnostic Groups: Secondary Analyses of 8 Studies Using the Utrecht Scale for Evaluation of Rehabilitation-Participation

OBJECTIVE

To determine differences in participation problems between diagnostic groups and to examine diagnosis as a determinant of participation with and without statistically accounting for confounders.

DESIGN

Secondary analyses of data from 8 studies.

SETTING

Community, the Netherlands.

PARTICIPANTS

Participants (N=1735) in diagnostic groups: stroke (n=534), subarachnoid hemorrhage (n=104), other acquired brain injury (n=163), progressive neurologic diseases (n=112), acute coronary syndrome (n=536), and spinal cord injury (n=286).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Participation was measured with the Utrecht Scale for Evaluation of Rehabilitation-Participation. This measure has 3 scales: Restrictions, Satisfaction, and Frequency. In this study, scores were also computed for 3 domains across these scales: Productivity, Leisure, and Social. Scores ranged from 0 (worst) up to 100 (best). Possible confounders were age, sex, level of education, marital status, and time since onset of the condition.

RESULTS

Significant differences were found in levels of participation between diagnostic groups. Individuals with acute coronary syndrome showed better participation scores in all scales and domains compared with most or all other diagnostic groups, except for the Social domain. Individuals with progressive neurologic diseases showed the lowest (worst) Restriction and Satisfaction scores, whereas those with stroke showed the lowest Frequency scores. After correcting for confounders, diagnosis explained significant proportions of the variance of participation (Frequency, 6.4%; Restrictions, 15.1%; Satisfaction, 5.1%; Productivity, 13.2%; Leisure, 13.8%; Social, 6.9%).

CONCLUSIONS

Participation problems occurred in all 6 diagnostic groups within this study. Differences were found in participation between diagnostic groups, demonstrating diagnosis-specific participation profiles, including after correcting for confounders.

Comparison between EQ-5D-5L and PROMIS-10 to evaluate health-related quality of life 3 months after stroke: a cross-sectional multicenter study

BACKGROUND

Although the use of patient-reported outcome measures to assess Health-Related Quality of Life (HRQoL) has been advocated, it is still open to debate which patient-reported outcome measure should be preferred to evaluate HRQoL after stroke.

AIM

To compare the measurement properties (including concurrent validity and discriminant ability) between the 5-dimensional 5-level EuroQol (EQ-5D-5L) and the Patient-Reported Outcomes Measurement Information System 10-Question Global Health Short Form (PROMIS-10) to evaluate HRQoL 3 months after stroke.

DESIGN

Cross-sectional study.

SETTING

Neurology outpatient clinics in 6 Dutch hospitals.

POPULATION

The participants 360 consecutive individuals with stroke. Their median age was 71 years, 143 (39.7%) were female and 335 (93.0%) had suffered an ischemic stroke.

METHODS

The EQ-5D-5L, PROMIS-10, modified Rankin Scale and two items on experienced decrease in health and activities post-stroke were administered by a stroke nurse or nurse practitioner through a telephone interview 3 months after stroke. The internal consistency, distribution, floor/ceiling effects, inter-correlations and discriminant ability (using the modified Rankin Scale and experienced decrease in health and in activities post-stroke as external anchors) were calculated for both the EQ-5D-5L and PROMIS-10.

RESULTS

Ninety-six percent of the participants were living at home and 50.9% experienced minimal or no disabilities (modified Rankin Scale 0-1) 3 months after stroke. A ceiling effect and a non-normal left skewed distribution were observed in the EQ-5D-5L. The PROMIS-10 showed higher internal consistency (α=0.90) compared to the EQ-5D-5L (α=0.75). Both the EQ-5D-5L and the PROMIS-10 were strongly correlated with the modified Rankin Scale (r=0.62 and 0.60 respectively). The PROMIS-10 showed better discriminant ability in less affected individuals with stroke, whereas the EQ-5D-5L showed slightly better discriminant ability in more affected individuals with stroke.

CONCLUSIONS

Both EQ-5D-5L and PROMIS-10 prove to be useful instruments to evaluate HRQoL in patients who are living at home 3 months after stroke.

CLINICAL REHABILITATION IMPACT

The clinical rehabilitation impact depended on the setting and underlying goal which patient-reported outcome measure is preferred to evaluate HRQoL 3 months after stroke. The PROMIS-10 should be preferred to detect differences in less affected stroke patients, whereas the EQ-5D-5L provides slightly more information in more affected stroke patients.

Reliability and Validity of the English Version of the AOSpine PROST (Patient Reported Outcome Spine Trauma)

STUDY DESIGN

Multicenter validation study.

OBJECTIVE

The aim of this study was to translate and adapt the AOSpine PROST (Patient Reported Outcome Spine Trauma) into English, and test its psychometric properties among North-American spine trauma patients.

SUMMARY OF BACKGROUND DATA

In the absence of an outcome instrument specifically designed and validated for traumatic spinal column injury patients, it is difficult to measure the effect size of various treatment options. The AOSpine Knowledge Forum Trauma initiated a project and developed the AOSpine PROST consisting of 19 items.

METHODS

Patients were recruited from two level-1 North-American trauma centers. For concurrent validity, next to AOSpine PROST also 36-item Short-Form Health Survey (SF-36) was filled out by patients. Patient characteristics were analyzed using descriptive statistics. Floor and ceiling effects as well as the number of inapplicable and missing questions were analyzed for content validity. Cronbach α and item-total correlation coefficients (ITCCs) were calculated for internal consistency. Spearman correlation tests were performed within AOSpine PROST items and in correlation to SF-36. Test-retest reliability was assessed using intraclass correlation coefficients (ICCs). Factor analysis was performed to explore any dimensions within AOSpine PROST.

RESULTS

The AOSpine PROST was translated adapted into English using established guidelines. Of 196 enrolled patients, 162 (82.7%) met the inclusion criteria and provided sufficient data. Content validity showed good results, and no floor and ceiling effects were seen. The internal consistency was excellent (Cronbach α = 0.97; ITCC 0.50-0.90) as well as test-retest reliability (ICC = 0.97). Spearman correlations were good (0.29-0.85). The strongest correlations of AOSpine PROST with SF-36 were seen with the physical components (0.69-0.82; P < 0.001). Factor analysis revealed two possible dimensions (Eigen values >1), explaining 75.7% of variance.

CONCLUSION

The English version of AOSpine PROST showed very good validity and reliability. It is considered as a valuable tool, and has the potential to contribute to the reduction of ongoing controversies in spine trauma care.

LEVEL OF EVIDENCE

2.

Reliability, validity and responsiveness of the Dutch version of the AOSpine PROST (Patient Reported Outcome Spine Trauma)

PURPOSE

To validate the Dutch version of AOSpine PROST (Patient Reported Outcome Spine Trauma).

METHODS

Patients were recruited from two level-1 trauma centers from the Netherlands. Next to the AOSpine PROST, patients also filled out SF-36 for concurrent validity. Descriptive statistics were used to analyze the characteristics. Content validity was assessed by evaluating the number of inapplicable or missing questions. Also floor and ceiling effects were analyzed. Internal consistency was assessed by calculating Cronbach's α and item-total correlation coefficients (itcc). Spearman correlation tests were performed within AOSpine PROST items and in correlation with SF-36. Test-retest reliability was analyzed using Intraclass Correlation Coefficients (ICC). Responsiveness was assessed by calculating effect sizes (ES) and standardized response mean (SRM). Factor analysis was performed to explore any dimensions within AOSpine PROST.

RESULTS

Out of 179 enrolled patients, 163 (91.1%) were included. Good results were obtained for content validity. No floor or ceiling effects were seen. Internal consistency was excellent (Cronbach's α = 0.96, itcc 0.50-0.86), with also good Spearman correlations (0.25-0.79). Compared to SF-36, the strongest correlation was seen for physical functioning (0.79; p < .001). Also test-retest reliability was excellent (ICC = 0.92). Concerning responsiveness analysis, very good results were seen with ES = 1.81 and SRM = 2.03 (p < 0.001). Factor analysis revealed two possible dimensions (Eigenvalues > 1), explaining 65.4% of variance.

CONCLUSIONS

Very satisfactory results were obtained for reliability, validity and responsiveness of the Dutch version of AOSpine PROST. Treating surgeons are encouraged to use this novel and validated tool in clinical setting and research to contribute to evidence-based and patient-centered care.

The International Spinal Cord Injury Survey: The Way Forward

As a community survey of individuals living with spinal cord injury in 22 countries, representing all 6 of the World Health Organization regions, the International Spinal Cord Injury (InSCI) community survey is one of the few surveys that highlights not only basic medical issues, but also the impact of spinal cord injury (SCI) on the everyday lives of people. The InSCI survey is part of a much larger project known as the Learning Health System for SCI Initiative (LHS-SCI). The objective of this article is to highlight some of the ongoing and planned next steps at the national and international levels. The implementation phase of the LHS-SCI initiative, beginning with the publication of primary results and extending until 2023, will use the results of the InSCI survey as evidence for implementation of recommendations for improving the societal response to the needs of individuals with SCI at the national level. To illustrate the variety of implementation activities currently underway, we provide country examples from Australia, Morocco, Malaysia, and Germany to demonstrate the diversity of approaches to the implementation of InSCI data. The implementation phase of the LHS-SCI initiative promises to usher in a new era of SCI research that will be seamlessly linked to ongoing and effective implementation actions, at both international and national levels and across settings from clinical practice, health systems management, and national policy.

Development and reliability of the AOSpine CROST (Clinician Reported Outcome Spine Trauma): a tool to evaluate and predict outcomes from clinician's perspective

PURPOSE

To report on the development of AOSpine CROST (Clinician Reported Outcome Spine Trauma) and results of an initial reliability study.

METHODS

The AOSpine CROST was developed using an iterative approach of multiple cycles of development, review, and revision including an expert clinician panel. Subsequently, a reliability study was performed among an expert panel who were provided with 20 spine trauma cases, administered twice with 4-week interval. The results of the developmental process were analyzed using descriptive statistics, the reliability per parameter using Kappa statistics, inter-rater rater agreement using intraclass correlation coefficient (ICC), and internal consistency using Cronbach's α.

RESULTS

The AOSpine CROST was developed and consisted of 10 parameters, 2 of which are only applicable for surgically treated patents ('Wound healing' and 'Implants'). A dichotomous scoring system ('yes' or 'no' response) was incorporated to express expected problems for the short term and long term. In the reliability study, 16 (84.2%) participated in the first round and 14 (73.7%) in the second. Intra-rater reliability was fair to good for both time points (κ = 0.40-0.80 and κ = 0.31-0.67). Results of inter-rater reliability were lower (κ = 0.18-0.60 and κ = 0.16-0.46). Inter-rater agreement for total scores showed moderate results (ICC = 0.52-0.60), and the internal consistency was acceptable (α = 0.76-0.82).

CONCLUSIONS

The AOSpine CROST, an outcome tool for the surgeons, was developed using an iterative process. An initial reliability analysis showed fair to moderate results and acceptable internal consistency. Further clinical validation studies will be performed to further validate the tool.

Recommendations for evaluation of neurogenic bladder and bowel dysfunction after spinal cord injury and/or disease

Objective: To provide an overview of clinical assessments and diagnostic tools, self-report measures (SRMs) and data sets used in neurogenic bladder and bowel (NBB) dysfunction and recommendations for their use with persons with spinal cord injury /disease (SCI/D).Methods: Experts in SCI/D conducted literature reviews, compiled a list of NBB related assessments and measures, reviewed their psychometric properties, discussed their use in SCI/D and issued recommendations for the National Institutes of Health (NIH), National Institute of Neurological Disorders and Stroke (NINDS) Common Data Elements (CDEs) guidelines.Results: Clinical assessments included 15 objective tests and diagnostic tools for neurogenic bladder and 12 for neurogenic bowel. Following a two-phase evaluation, eight SRMs were selected for final review with the Qualiveen and Short-Form (SF) Qualiveen and the Neurogenic Bowel Dysfunction Score (NBDS) being recommended as supplemental, highly-recommended due to their strong psychometrics and extensive use in SCI/D. Two datasets and other SRM measures were recommended as supplemental.Conclusion: There is no one single measure that can be used to assess NBB dysfunction across all clinical research studies. Clinical and diagnostic tools are here recommended based on specific medical needs of the person with SCI/D. Following the CDE for SCI studies guidelines, we recommend both the SF-Qualiveen for bladder and the NBDS for bowel as relatively short measures with strong psychometrics. Other measures are also recommended. A combination of assessment tools (objective and subjective) to be used jointly across the spectrum of care seems critical to best capture changes related to NBB and develop better treatments.

Patients' views on their decision making during inpatient rehabilitation after newly acquired spinal cord injury-A qualitative interview-based study

Introduction

Involving patients in decision making is a legal requirement in many countries, associated with better rehabilitation outcomes, but not easily accomplished during initial inpatient rehabilitation after severe trauma. Providing medical treatment according to the principles of shared decision making is challenging as a point in case for persons with spinal cord injury (SCI).

Objectives

The aim of this study was to retrospectively explore the patients’ views on their participation in decision making during their first inpatient rehabilitation after onset of SCI, in order to optimize treatment concepts.

Methods

A total of 22 participants with SCI were interviewed in‐depth using a semi‐structured interview scheme between 6 months and 35 years post‐onset. Interviews were transcribed verbatim and analysed with the Mayring method for qualitative content analysis.

Results

Participants experienced a substantially reduced ability to participate in decision making during the early phase after SCI. They perceived physical, psychological and environmental factors to have impacted upon this ability. Patients mentioned regaining their ability to make decisions was an important goal during their first rehabilitation. Receiving adequate information in an understandable and personalized way was a prerequisite to achieve this goal. Other important factors included medical and psychological condition, personal engagement, time and dialogue with peers.

Conclusion

During the initial rehabilitation of patients with SCI, professionals need to deal with the discrepancy between the obligation to respect a patient's autonomy and their diminished ability for decision making.

The selection of core International Classification of Functioning, Disability, and Health (ICF) categories for patient-reported outcome measurement in spine trauma patients-results of an international consensus process

BACKGROUND CONTEXT

There is no outcome instrument specifically designed and validated for spine trauma patients without complete paralysis, which makes it difficult to compare outcomes of different treatments of the spinal column injury within and between studies.

PURPOSE

The paper aimed to report on the evidence-based consensus process that resulted in the selection of core International Classification of Functioning, Disability, and Health (ICF) categories, as well as the response scale for use in a universal patient-reported outcome measure for patients with traumatic spinal column injury.

STUDY DESIGN/SETTING

The study used a formal decision-making and consensus process.

PATIENT SAMPLE

The sample includes patients with a primary diagnosis of traumatic spinal column injury, excluding completely paralyzed and polytrauma patients.

OUTCOME MEASURES

The wide array of function and health status of patients with traumatic spinal column injury was explored through the identification of all potentially meaningful ICF categories.

METHODS

A formal decision-making and consensus process integrated evidence from four preparatory studies. Three studies aimed to identify relevant ICF categories from three different perspectives. The research perspective was covered by a systematic literature review identifying outcome measures focusing on the functioning and health of spine trauma patients. The expert perspective was explored through an international web-based survey among spine surgeons from the five AOSpine International world regions. The patient perspective was investigated in an international empirical study. A fourth study investigated various response scales for their potential use in the future universal outcome instrument. This work was supported by AOSpine. AOSpine is a clinical division of the AO Foundation, an independent medically guided non-profit organization. The AOSpine Knowledge Forums are pathology-focused working groups acting on behalf of AOSpine in their domain of scientific expertise.

RESULTS

Combining the results of the preparatory studies, the list of ICF categories presented at the consensus conference included 159 different ICF categories. Based on voting and discussion, 11 experts from 6 countries selected a total of 25 ICF categories as core categories for patient-reported outcome measurement in adult traumatic spinal column injury patients (9 body functions, 14 activities and participation, and 2 environmental factors). The experts also agreed to use the Numeric Rating Scale 0-100 as response scale in the future universal outcome instrument.

CONCLUSIONS

A formal consensus process integrating evidence and expert opinion led to a set of 25 core ICF categories for patient-reported outcome measurement in adult traumatic spinal column injury patients, as well as the response scale for use in the future universal disease-specific outcome instrument. The adopted core ICF categories could also serve as a benchmark for assessing the content validity of existing and future outcome instruments used in this specific patient population.

Longitudinal course of depressive symptoms and anxiety after aneurysmal subarachnoid hemorrhage

BACKGROUND

Symptoms of anxiety and depression are present in almost half of the patients who survive an aneurysmal subarachnoid hemorrhage (aSAH), but the long-term course is unknown.

AIM

To study the longitudinal course and predictors of symptoms of anxiety and depression after aSAH.

DESIGN

Prospective longitudinal study with test occasions at 3 months (baseline), 1 year (T2) and 2-5 years (T3) post-aSAH.

SETTING

SAH outpatient clinic.

POPULATION

One hundred forty-three patients visiting the outpatient clinic.

METHODS

Patients visiting our outpatient clinic 3 months after aSAH and living independently in the community completed the Beck Depression Inventory-II-NL and the State-Trait Anxiety Inventory at 3 months (T1), one year (T2) and 2-5 years (T3). Potential predictors were collected at T1.

RESULTS

Complete datasets from 93 patients were analyzed. Depressive symptoms were present in 39% (T1), 41% (T2) and 54% (T3) of patients, symptoms of anxiety in 52% (T1), 48% (T2) and 53% (T3). Of patients with depressive symptoms at T1, 72% still had symptoms at T3, compared to 67% for anxiety. Disability on the Glasgow Outcome Scale (GOS), passive coping (UCL-PR) and depressive symptoms at T1 were significantly independent variables explaining 52% of the variance of depressive symptoms at T2. GOS and UCL-PR at T1 were variables explaining 25% of the variance of depressive symptoms at T3. Depressive symptoms and anxiety at T1 were predictive variables for anxiety at T2 (explained variance 43%) and UCL-PR for anxiety at T3 (explained variance 21%).

CONCLUSIONS

The prevalence of symptoms of depression and anxiety remained high during the first 2-5 years after aSAH. Passive coping at 3 months after aSAH was the most consistent predictor of symptoms of anxiety and depression in the long term.

CLINICAL REHABILITATION IMPACT

Since many patients who are initially free of symptoms of depression and anxiety develop such symptoms over time, we advocate screening for these symptoms and coping strategies to identify these patients and apply targeted therapy.

Return to work after major trauma

Objective : To quantify the prevalence of return to work after major trauma, and to investigate the determinants of postinjury work status.

Design : Prospective cohort study.

Setting : University Medical Centre Utrecht, a level 1 trauma centre in the Netherlands.

Method : All severely injured (ISS > 16) adult (age = 16 +) trauma survivors admitted from January 1999 to December 2000 who were full-time employed at the time of the injury were selected for follow-up (n = 214). Response rate was 93%. Outcome was assessed at a mean of 15 months (SD = 1.5) after injury. Multivariate logistic regression analyses identified determinants at hospital discharge and at follow-up.

Results : Following injury 58.4% of the patients (n = 125) were able to return to full-time employment, 21.5% had a part-time job, and 20.1% did not return to work. Univariate analysis yielded the following significant determinants of postinjury work status: age, comorbidity, injury severity score, brain injury, spinal cord injury, length of stay in an intensive care unit, hospital stay, discharge destination, percentage of permanent impairment (according to the fourth American Medical Association guide (AMA)), limitations in activities of daily living and cognitive complaints. Logistic regression analyses (23% explained variance) identified spinal cord injury, duration of hospital stay, discharge destination and age as determinants of return to work at hospital discharge. At follow-up, determinants of return to work included AMA, activities of daily living, cognitive complaints and being discharged home (51% explained variance).

Conclusions : Around 60% of the patients returned to their pre-injury work status after major trauma. The return to work rate was only partly explained by disability at follow-up. Independent determinants of return to work differ with the time of assessment.

What to Do With "Moderate" Reliability and Validity Coefficients?

Clinimetric studies may use criteria for test-retest reliability and convergent validity such that correlation coefficients as low as .40 are supportive of reliability and validity. It can be argued that moderate (.40-.60) correlations should not be interpreted in this way and that reliability coefficients <.70 should be considered as indicative of unreliability. Convergent validity coefficients in the .40 to .60 or .40 to .70 range should be considered as indications of validity problems, or as inconclusive at best. Studies on reliability and convergent should be designed in such a way that it is realistic to expect high reliability and validity coefficients. Multitrait multimethod approaches are preferred to study construct (convergent-divergent) validity.

Is There an Association Between Markers of Cardiovascular Autonomic Dysfunction at Discharge From Rehabilitation and Participation 1 and 5 Years Later in Individuals With Spinal Cord Injury?

OBJECTIVES

To determine whether physical activity and participation 1 and 5 years after discharge are associated with measures of cardiovascular autonomic function: prevalence of hypotension and reduced peak heart rate at discharge from initial inpatient spinal cord injury (SCI) rehabilitation.

DESIGN

Prospective cohort study.

SETTING

Rehabilitation centers.

PARTICIPANTS

Individuals with SCI (N=146).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

We recorded markers of cardiovascular autonomic dysfunction (resting blood pressure and peak heart rate) and personal and lesion characteristics at the time of discharge from rehabilitation. Parameters for participation (social health status dimension of the Sickness Impact Profile) and physical activity (Physical Activity Scale for Individuals with Physical Disabilities [PASIPD]) were measured 1 and 5 years after discharge. Effects of prevalence of cardiovascular autonomic dysfunction were analyzed using linear regression analysis while correcting for possible confounders.

RESULTS

We found no significant association between hypotension and social health status dimension of the Sickness Impact Profile or PASIPD, either at 1 or at 5 years after discharge. A significant association between peak heart rate and social health status dimension of the Sickness Impact Profile was found at 1 year after discharge, showing poorer participation in individuals with low peak heart rate (ie, cardiovascular autonomic dysfunction). The unadjusted relation between peak heart rate and the social health status dimension of the Sickness Impact Profile was significant at 5 years, but not when adjusted for confounders. We found associations between peak heart rate and PASIPD for both 1 and 5 years after discharge; however, these were not significant after correction for potential confounding factors.

CONCLUSIONS

Autonomic dysfunction after SCI is a crucial factor influencing quality of life. We found that cardiovascular autonomic impairment, assessed from low peak heart rate, was associated with reduced participation after 1 year. The results suggest that peak heart rate at discharge from rehabilitation after SCI should be used to identify those needing additional support to facilitate physical activity and participation after discharge.

Development of the International Spinal Cord Injury Activities and Participation Basic Data Set

STUDY DESIGN

Consensus decision-making process.

OBJECTIVES

The objective of this study was to develop an International Spinal Cord Injury (SCI) Activities and Participation (A&P) Basic Data Set.

SETTING

International working group.

METHODS

A committee of experts was established to select and define A&P data elements to be included in this data set. A draft data set was developed and posted on the International Spinal Cord Society (ISCoS) and American Spinal Injury Association websites and was also disseminated among appropriate organizations for review. Suggested revisions were considered, and a final version of the A&P Data Set was completed.

RESULTS

Consensus was reached to define A&P and to incorporate both performance and satisfaction ratings. Items that were considered core to each A&P domain were selected from two existing questionnaires. Four items measuring activities were selected from the Spinal Cord Independence Measure III to provide basic data on task execution in activities of daily living. Eight items were selected from the Craig Handicap Assessment and Reporting Technique to provide basic data on the frequency of participation. An additional rating of satisfaction on a three-point scale for each item completes the total of 24 A&P variables.

CONCLUSION

Collection of the International SCI A&P Basic Data Set variables in all future research on SCI outcomes is advised to facilitate comparison of results across published studies from around the world. Additional standardised instruments to assess activities of daily living or participation can be administered, depending on the purpose of a particular study.

Psychological factors determine depressive symptomatology after stroke

OBJECTIVE

To identify psychological factors related to poststroke depressive symptoms.

DESIGN

Cross-sectional study, with patients assessed at 2 months poststroke.

SETTING

Patients with stroke from 6 general hospitals.

PARTICIPANTS

Stroke patients (N=344; mean age ± SD, 66.9±12.3y).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The presence of clinical depressive symptoms was determined with the depression subscale of the Hospital Anxiety and Depression Scale 2 months poststroke. Psychological factors assessed were extraversion, neuroticism, optimism, pessimism, self-efficacy, helplessness, acceptance, perceiving benefits, proactive coping, and passive coping.

RESULTS

Bivariate correlations and multivariate backward logistic regression were used to analyze associations between psychological factors and poststroke depressive symptoms, accounting for demographic and stroke-related factors. More neuroticism, pessimism, passive coping, and helplessness, and less extraversion, optimism, self-efficacy, acceptance, perceived benefits, and proactive coping were bivariately associated with the presence of depressive symptoms. Multivariate logistic regression analysis showed that more helplessness (odds ratio [OR]=1.17) and passive coping (OR=1.19) and less acceptance (OR=.89) and perceived benefits (OR=.89) were independently significantly associated with the presence of poststroke depressive symptoms (Nagelkerke R(2)=.49).

CONCLUSIONS

We found a relationship between psychological variables and the presence of depressive symptoms 2 months poststroke. It is important to take these factors into account during poststroke rehabilitation.

Outcomes of neurogenic bowel management in individuals living with a spinal cord injury for at least 10 years

OBJECTIVE

To describe bowel management and its outcomes in individuals living with a spinal cord injury (SCI) for at least 10 years.

DESIGN

Cross-sectional multicenter study.

SETTING

Dutch community.

PARTICIPANTS

Individuals (N=258; age range, 28-65y) who acquired their SCI between 18 and 35 years of age, who were at least 10 years post-SCI, and who used a wheelchair for their daily mobility.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The International SCI Bowel Function Basic Data Set, the neurogenic bowel dysfunction (NBD) score, and a single item on satisfaction with bowel management.

RESULTS

Mean time since injury (TSI) was 24±9 years. Seventy-four percent used ≥1 conservative bowel management method, specifically digital evacuation (35%) and mini enemas (31%). Transanal irrigation (TAI) and surgical interventions were used by 11% and 8%, respectively. Perianal problems were reported by 45% of the participants. Severe NBD was present in 36% of all participants and in 40% of those using a conservative method. However, only 14% were (very) dissatisfied with their current bowel management. Dissatisfaction with bowel management was significantly associated with constipation and severe NBD. With increasing TSI, there was a nonsignificant trend observed toward a decline in dissatisfaction with bowel management and a significant decline in severe NBD.

CONCLUSIONS

Although satisfaction rates were high, more than a third of the participants reported severe NBD and perianal problems. Apart from severe NBD, there were no significant associations between bowel problems and TSI. Conservative methods were most often used, but some of these methods were also significantly associated with the presence of severe NBD. Longitudinal research is necessary to provide more knowledge concerning the course of NBD with increasing TSI.

Assessment of health-related quality of life of clients in vocational rehabilitation: association with depressive symptoms and type of services

BACKGROUND

Health-related quality of life (HRQOL) has been frequently used as an outcome measure in disability-related studies, yet little is known about HRQOL in vocational rehabilitation (VR).

AIM

To evaluate HRQOL in VR clients and identify factors associated with their HRQOL DESIGN, SETTING AND POPULATION: Cross-sectional study of 149 clients from 5 VR centers in Switzerland and Germany

METHODS

HRQOL was measured by 8 dimensions of the Medical Outcomes Study 36-item Short Form Health Survey (SF-36) and compared with sex-matched German population norms. Multiple regression analyses were conducted to identify whether VR-related variables (VR duration and type, sick leave duration) and depressive symptoms were associated with HRQOL dimensions independent of sociodemographics (age, sex, education) and clinical characteristics (type of disorders, number of comorbidities)

RESULTS

HRQOL in VR clients was significantly lower in all dimensions measured by the SF-36 compared to the general population. Returning to the former workplace and being oriented to a new job were associated with less functional limitation due to physical problems, less pain and better mental health. Being oriented to a new job was also associated with better vitality. Presence of depressive symptoms was negatively related with all dimensions of HRQOL. Overall, the regression models explained 10%-25% variance of the physical HRQOL domain and 18%-27% variance of the mental HRQOL domain.

CONCLUSION

Multiple dimensions of HRQOL were significantly decreased in VR clients. Depressive symptoms were prevalent and contributed significantly to poorer HRQOL, thus should be considered in the VR process. Further research is needed to ascertain the effect of different VR types to HRQOL and to elaborate the role of depressive symptoms in HRQOL over time.

CLINICAL REHABILITATION IMPACT

Rehabilitation professionals should be informed of the level of HRQOL in VR clients in order to tailor effective interventions to improve HRQOL by not only focusing on functional ability but also the psychological well-being.

Trajectories of musculoskeletal shoulder pain after spinal cord injury: Identification and predictors

OBJECTIVE/BACKGROUND

Although shoulder pain is a problem in up to 86% of persons with a spinal cord injury (SCI), so far, no studies have empirically identified longitudinal patterns (trajectories) of musculoskeletal shoulder pain after SCI. The objective of this study was: (1) to identify distinct trajectories of musculoskeletal shoulder pain in persons with SCI, and (2) to determine possible predictors of these trajectories.

DESIGN/METHODS

Multicenter, prospective cohort study in 225 newly injured persons with SCI.

OUTCOME MEASURE

Shoulder pain was assessed on five occasions up to 5 years after discharge. Latent class growth mixture modeling was used to identify the distinct shoulder pain trajectories.

RESULTS

Three distinct shoulder pain trajectories were identified: (1) a "No or Low pain" trajectory (64%), (2) a "High pain" (30%) trajectory, and (3) a trajectory with a "Decrease of pain" (6%). Compared with the "No or Low pain" pain trajectory, the "High pain" trajectory consisted of more persons with tetraplegia, shoulder pain before injury, limited shoulder range of motion (ROM), lower manual muscle test scores, or more spasticity at t1. Multiple logistic regression analysis showed two significant predictors for the "High pain" trajectory (as compared with the "No or Low pain" trajectory): having a tetraplegia (odds ratio (OR) = 3.2; P = 0.002) and having limited shoulder ROM (OR = 2.8; P = 0.007).

CONCLUSION

Shoulder pain in people with SCI follows distinct trajectories. At risk for belonging to the "High pain" trajectory are persons with tetraplegia and those with a limited shoulder ROM at start of active rehabilitation.

Trajectories in the course of body mass index after spinal cord injury

OBJECTIVE

To identify different trajectories of the course of body mass index (BMI) after spinal cord injury (SCI) and to study whether other cardiovascular risk factors (blood pressure, lipid profile) follow the same trajectories.

DESIGN

Multicenter prospective cohort study with measurements at the start of active rehabilitation, after 3 months, at discharge, and 1 and 5 years after discharge.

SETTING

Rehabilitation centers.

PARTICIPANTS

Persons with a recent SCI (N=204).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

BMI trajectories.

RESULTS

Three BMI trajectories were identified: (1) a favorable stable BMI during and after rehabilitation (± 22-23 kg/m(2)) (54%); (2) a higher but stable BMI during inpatient rehabilitation (± 24 kg/m(2)) and an increase after discharge (up to 29 kg/m(2)) (38%); and (3) an increase in BMI during inpatient rehabilitation (from ± 23 up to 28 kg/m(2)) and leveling off after discharge (8%). Profile analyses showed that an unfavorable change in BMI was not accompanied by clear unfavorable changes in blood pressure or lipid levels.

CONCLUSIONS

BMI in people with SCI follows distinct trajectories. Monitoring body mass, food intake, and daily physical activity during and especially after inpatient SCI rehabilitation is important to prevent obesity and related cardiovascular risk factors.

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

STUDY DESIGN

This was a prospective cohort study.

OBJECTIVES

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

SETTING

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

METHODS

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

RESULTS

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

CONCLUSION

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

Patterns of changes in wheelchair exercise capacity after spinal cord injury

OBJECTIVES

(1) To identify different patterns of changes in wheelchair exercise capacity in the period between the start of active spinal cord injury (SCI) rehabilitation and 5 years after discharge; (2) to examine the pattern determinants of the change in wheelchair exercise capacity.

DESIGN

Prospective cohort study. Measurements were recorded at the start of active inpatient rehabilitation, 3 months after the start, at discharge of inpatient rehabilitation, 1 year after discharge, and 5 years after discharge.

SETTING

Eight rehabilitation centers.

PARTICIPANTS

Persons with SCI (N=130; age range, 18-65y), who were wheelchair-dependent, at least for long distances.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

Wheelchair exercise capacity: peak power output (W).

RESULTS

We found 4 different patterns of the change of peak power output (mean ± SD): (1) a pattern with high and progressive scores (33% of total study group): high progressive scores (start of rehabilitation: 49±15W to 5 years after discharge: 77±17.2W); (2) a pattern of improvement during inpatient rehabilitation and deterioration after inpatient rehabilitation (12%): progressive scores during inpatient rehabilitation with deteriorating scores after discharge (start of rehabilitation: 29±8.7W, to discharge: 60±8.4W, to 5 years after discharge: 39±13.1W); (3) a pattern with low and only slightly progressive scores (52%): low progressive scores (start of rehabilitation: 20±10.1W to 5 years after discharge: 31±15.9W); and (4) a pattern with low scores during inpatient rehabilitation and a sharp rise after discharge (3%): low inpatient scores with strong progressive scores after discharge (start of rehabilitation: 29±15.5W to 5 years after discharge: 82±10.6W). A logistic regression of factors that may distinguish between patterns with high and progressive scores and patterns with low and only slightly progressive scores revealed that older age, being a woman, having a tetraplegic lesion, and low functional status were associated with patterns with low and only slightly progressive scores. The pattern of improvement during inpatient rehabilitation and deterioration after inpatient rehabilitation showed more neuropathic pain and lower sports participation than patterns with high and progressive scores.

CONCLUSIONS

For the vast majority of patients, wheelchair exercise capacity after SCI shows a positive trend and can be described in distinct patterns that are dependent on personal, lesion, and functional characteristics.

Longitudinal association between lifestyle and coronary heart disease risk factors among individuals with spinal cord injury

OBJECTIVE

To investigate: (1) the course of coronary heart disease risk factors (lipid profiles and body mass index (BMI)) in the first five years after discharge from inpatient spinal cord injury (SCI) rehabilitation and (2) the association between lifestyle (physical activity, self-care related to fitness, smoking, alcohol, body mass and low-fat diet) and coronary heart disease risk factors during that period.

DESIGN

Prospective cohort study.

PARTICIPANTS/METHODS

Individuals with SCI (N=130). Total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides (TG) and BMI were determined at discharge from inpatient rehabilitation and 1 and 5 years after discharge. Using multilevel regression models, the effects of lifestyle (drinking alcohol, smoking, active lifestyle and self-care) on the lipid profiles and BMI were determined.

RESULTS

After correction for lesion and personal characteristics, no changes in lipid profiles in the five years after discharge were seen, whereas the BMI increased significantly with 1.8 kg m(-2). A high percentage was at risk of cardiovascular disease due to high BMI (63-75%) or HDL (66-95%). The individuals who indicated to maintain their fitness level as good as possible and the individuals with a low BMI showed better lipid profiles. Individuals with a more active lifestyle showed higher HDL levels. Individuals who avoid smoking showed a 1.5 kg m(-2) higher BMI.

CONCLUSION

Lipid profiles seem to stabilize in the years after discharge from inpatient SCI rehabilitation, whereas the BMI increased. Lifestyle factors associated with a favorable lipid profile and BMI could be identified.

Return to work five years after spinal cord injury inpatient rehabilitation: is it related to wheelchair capacity at discharge?

OBJECTIVE

To describe the proportion of people with spinal cord injury who returned to work 5 years after discharge from inpatient rehabilitation, and to investigate whether return to work is related to wheelchair capacity at discharge from inpatient rehabilitation.

DESIGN

Multi-centre prospective cohort study.

SUBJECTS

A total of 103 participants with acute spinal cord injury at 8 Dutch rehabilitation centres, specialized in the rehabilitation of spinal cord injury. All participants were in paid employment before injury.

METHODS

Main outcome measure was return to work for at least 1 h per week. The independent variables of wheelchair capacity were peak oxygen uptake (VO2peak), peak aerobic power output (POpeak), and wheelchair skill scores (ability, performance time, and physical strain). Possible confounders were age, gender, lesion level and lesion completeness, and educational level.

RESULTS

The proportion of participants who returned to work was 44.7%. After correction for the confounders, POpeak (p=0.028), ability score (p=0.022), performance time (p=0.019) and physical strain score (p=0.038) were significantly associated with return to work. VO2peak was not significantly associated with return to work.

CONCLUSION

More than 40% of the participants were able to return to paid work within 5 years after discharge from inpatient rehabilitation. Return to work was related to wheelchair capacity at discharge. It is recommended to train wheelchair capacity during rehabilitation in the context of return to work, since the association with return to work is another benefit of the training of wheelchair capacity in addition to the improvement of mobility and functional independency.

Life satisfaction in patients with chronic musculoskeletal pain and its predictors

PURPOSE

To determine the life satisfaction of patients with chronic non-malignant musculoskeletal pain (CMP) compared to the general population (GP) and to identify predictors of life satisfaction.

METHODS

Subjects were patients with CMP (n = 1,082) admitted to multidisciplinary rehabilitation and a general population sample (n = 506). Lisat-9 measures satisfaction with life as a whole and eight life domains. Physical, emotional and social functioning and pain intensity were assessed using the SF-36. Ordinal logistic regression was used to analyse differences between patients with CMP and the GP, and predictors of life satisfaction in patients with CMP.

RESULTS

Compared to the general population, patients with CMP reported lower satisfaction with 'life as a whole', and with six life domains: self-care, leisure, vocational and financial situation, sex life and contacts with friends. In the CMP group, pain was associated with satisfaction with self-care, vocational situation, partnership, family life and contacts with friends. Marital status, age and mental health were associated with most satisfaction scores.

CONCLUSIONS

Compared to the general population, patients with CMP reported lower satisfaction with 'life as a whole' and most life domains. The most consistent predictors of life satisfaction were marital status, mental health, vitality and pain.

Changes and determinants of life satisfaction after spinal cord injury: a cohort study in the Netherlands

OBJECTIVE

To determine the impact of spinal cord injury (SCI) on life satisfaction of persons with SCI 1 year after discharge of inpatient rehabilitation.

DESIGN

A cohort study. Life satisfaction before SCI was retrospectively measured at the start of active rehabilitation. One year after discharge from inpatient rehabilitation, current life satisfaction was measured.

SETTING

Eight rehabilitation centers in The Netherlands.

PARTICIPANTS

Persons (N=147) aged 18 to 65 and wheelchair-dependent at least for long distances.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

The Life Satisfaction Questionnaire.

RESULTS

Mean satisfaction with life +/- SD as a whole was 5.3+/-0 before SCI and 4.3+/-1.3 one year after inpatient rehabilitation. Sexual life, self-care, and vocational situation showed the largest impact of SCI (P<.05), whereas the social relationships domains appeared to be the least affected. Decrease of life satisfaction after SCI was larger when using the retrospective ratings than when using general population scores. Significant determinants of life satisfaction after SCI were high lesion level (beta=.31, P<.05), pain (beta=.19, P<.05), and secondary impairments (beta=.22, P<.05).

CONCLUSIONS

Life satisfaction decreased in persons with SCI. Level of lesion and suffering secondary impairments or pain were associated with low life satisfaction 1 year after discharge from inpatient rehabilitation.

Feasibility of a classification system for physical therapy, occupational therapy, and sports therapy interventions for mobility and self-care in spinal cord injury rehabilitation

OBJECTIVE

To test the feasibility of a classification system developed to record the contents of treatment sessions intended to improve mobility and self-care by persons with a spinal cord injury (SCI) in clinical rehabilitation.

DESIGN

Descriptive study.

SETTING

Three Dutch SCI facilities.

PARTICIPANTS

Participants (N=36) as well as physical therapists (n=20), occupational therapists (n=14), and sports therapists (n=2).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Questionnaires to assess the clarity of the classification system, time needed to record 1 treatment session, and the distribution of categories and interventions. The classification system consisted of 28 categories at 3 levels of functioning: basic functions (eg, muscle power), basic activities (eg, transfers), and complex activities (eg, walking and moving around outside).

RESULTS

Therapists used 1625 codes to record 856 treatment sessions of 142 patients. For 93% of the treatment sessions, the coding caused little or no doubt. The therapists were able to classify 86.3% of the treatment sessions within 3 minutes. The classification system was rated as useful and easy to use.

CONCLUSIONS

The findings support the suitability of our classification system as a tool to record the contents of SCI treatment sessions in different settings and by different therapists.

Validity of the Dutch version of the Amyotrophic Lateral Sclerosis Assessment Questionnaire, ALSAQ-40, ALSAQ-5

The objective was to validate the Dutch translation of the 40-item and 5-item Amyotrophic Lateral Sclerosis Assessment Questionnaire (ALSAQ-40, ALSAQ-5). Eighty-one ALS patients participated in this cross-sectional study. The measures used were the ALSAQ-40, the ALSAQ-5, MOS Short-Form-36 (SF-36) and Revised ALS Functional Rating Scale (ALSFRS-R). The Dutch ALSAQ-40 was sensitive to differences in disease severity (all scales Kruskal-Wallis, p<0.05), had no floor and few ceiling effects (Communication, Eating and Drinking scales), had excellent internal consistency reliability (all scales Cronbach's alpha >0.90, all item to subscale correlations above 0.40) and showed good construct validity as it correlated as expected with SF-36 and ALSFRS-R scores. The total and item scores of the ALSAQ-5 were strongly correlated with the corresponding total and subscale scores of the ALSAQ-40 (Spearman's rho >0.80). The ALSAQ-5 and ALSAQ-40 showed comparable correlations with the subscales of the SF-36 and the ALSFRS-R, except for Activities Daily Living and Independence (ADL). All other results of the Dutch ALSAQ-40 and ALSAQ-5 were comparable to those of the original UK questionnaires. It is concluded that the psychometric properties of the Dutch version of the ALSAQ-40 and the ALSAQ-5 are good and similar to those of the original English version.

Complications following spinal cord injury: Occurrence and risk factors in a longitudinal study during and after inpatient rehabilitation

OBJECTIVE

To assess the occurrence and risk factors for complications following spinal cord injury during and after inpatient rehabilitation.

DESIGN

Multicentre longitudinal study.

SUBJECTS

A total of 212 persons with a spinal cord injury admitted to specialized rehabilitation centres.

METHODS

Assessments at the start of active rehabilitation (n=212), 3 months later (n=143), at discharge (n=191) and 1 year after discharge (n=143).

RESULTS

Multi-level random coefficient analyses revealed that complications were common following spinal cord injury. Most subjects reported neurogenic and musculoskeletal pain, or had spasticity at each assessment. During the year after discharge, complications remained common: urinary tract infections and pressure sores affected 49% and 36% of the population, respectively. The degree of pain decreased, whereas the degree of spasticity increased significantly during inpatient rehabilitation. Overall, increased age, increased body mass index, traumatic lesion, tetraplegia, and complete lesion all increased the risk of complications.

CONCLUSION

Complications are common following spinal cord injury. They need specific attention after discharge from inpatient rehabilitation and within subpopulations.

Subject- and Injury-Related Factors Influencing the Course of Manual Wheelchair Skill Performance During Initial Inpatient Rehabilitation of Persons With Spinal Cord Injury

OBJECTIVES

To study changes in wheelchair skills in subjects with spinal cord injury (SCI) during rehabilitation; to determine whether changes in wheelchair skill performance are related to the subject, lesion characteristics, secondary complications, and upper extremity pain; and to investigate if wheelchair skill performance at discharge can be predicted from these features.

DESIGN

Longitudinal. Subjects performed the Wheelchair Circuit 3 times during rehabilitation: at admission (t1), 3 months later (t2), and at discharge (t3).

SETTING

Eight rehabilitation centers in the Netherlands.

PARTICIPANTS

One hundred twenty-one subjects with SCI.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The Wheelchair Circuit consists of 8 wheelchair skills and results in 3 test scores: ability, performance time, and physical strain.

RESULTS

All the scores of the Wheelchair Circuit improved significantly between t1 and t2, and between t2 and t3. The scores were related to age and lesion level, whereas changes in scores were related to age, sex, lesion level, and secondary complications. The variables age, body mass index, sex, lesion level, motor completeness, and secondary complications contributed significantly to the prediction of the scores at t3.

CONCLUSIONS

Wheelchair skill performance improved during rehabilitation. Personal and lesion characteristics are most important for improving wheelchair skill performance and predicting wheelchair skill performance.
