Dutch Dataset Vocational Rehabilitation for Chronic Musculoskeletal Pain: Baseline Patients' Characteristics and Program Eligibility.

PURPOSE: Vocational rehabilitation (VR) is an intervention to improve return to work for patients with chronic musculoskeletal pain (CMP). However, a systematic overview of characteristics of referred patients or eligible for VR is lacking, which hinders comparability across studies. Objectives were (1) to describe characteristics of patients with CMP referred to and eligible for VR and (2) to identify factors that contribute to VR eligibility. METHODS: This study used a multicenter, cross-sectional design. Data of self-reported questionnaires were obtained between 2013 and 2019 from care as usual of eight Dutch VR centers. Descriptive statistics were performed to describe sociodemographic, pain-related, and work-related characteristics. Logistic regression analysis was used to identify factors contributing to VR eligibility. RESULTS: Data sets of n = 2970 referred patients were included. The mean age was 46 years and 60% were female. Low back (43%), neck (37%), and shoulder pain (34%) were most reported. 82% Worked in paid employment. The absenteeism rate was 85%, and 44% was partially absent. After multidisciplinary screening, 62.2% were eligible for VR. Persons most likely to be eligible for VR (OR < 1.20) were those having back or neck pain, whereas least eligible (OR < 0.80) were persons having pain in hand/fingers or pain in other regions, unemployed workers, and those referred by a 'other' medical specialists. All other factors contributed little or none to the model. CONCLUSIONS: An extensive description of sociodemographic, pain-related, and work-related characteristics is presented for patients eligible for VR. Especially having back/neck pain and being an employee were associated with higher chance of eligibility for VR.

Effective bowel management in spinal cord injury during inpatient rehabilitation: data from the Dutch spinal cord injury database.

STUDY DESIGN: Retrospective Observational Study. OBJECTIVES: To describe bowel management in individuals with a recently acquired spinal cord injury (SCI) both at admittance and discharge from first inpatient rehabilitation, and to determine factors that contribute to effective bowel management (EBM) at discharge. SETTING: Specialized rehabilitation centers in the Netherlands. METHODS: Data from the Dutch Spinal Cord Injury Database (DSCID) collected between 2015 and 2019 was used. EBM was defined by the variables of stool frequency and fecal incontinence. After univariate analysis, a multivariate regression analysis was conducted. RESULTS: Of 1,210 participants, 818 (68%) did not have EBM at admittance. At discharge, 308 (38%) did still not have EBM (in total 33% of all participants). The odds of having EBM at discharge was 2.82 times higher for participants with ASIA Impairment Scale (AIS) D compared to those with AIS-A (95% CI: 1.38-5.78). Participants with non-traumatic SCI had higher odds of having EBM than those with traumatic SCI (OR: 0.59, 95% CI 0.38-0.91). Use of suppositories, small enema, medication influencing bowel function, and oral laxatives at admittance did not influence EBM significantly at discharge. CONCLUSIONS: Bowel management improves during first inpatient rehabilitation. However, realizing EBM after a recently acquired SCI is a challenge. This endorses the importance of bowel management during inpatient rehabilitation, especially for people with AIS-A and non-traumatic etiology.

Gait training after spinal cord injury: safety, feasibility and gait function following 8 weeks of training with the exoskeletons from Ekso Bionics.

STUDY DESIGN: Prospective quasi-experimental study, pre- and post-design. OBJECTIVES: Assess safety, feasibility, training characteristics and changes in gait function for persons with spinal cord injury (SCI) using the robotic exoskeletons from Ekso Bionics. SETTING: Nine European rehabilitation centres. METHODS: Robotic exoskeleton gait training, three times weekly over 8 weeks. Time upright, time walking and steps in the device (training characteristics) were recorded longitudinally. Gait and neurological function were measured by 10 Metre Walk Test (10 MWT), Timed Up and Go (TUG), Berg Balance Scale (BBS), Walking Index for Spinal Cord Injury (WISCI) II and Lower Extremity Motor Score (LEMS). RESULTS: Fifty-two participants completed the training protocol. Median age: 35.8 years (IQR 27.5-52.5), men/women: N = 36/16, neurological level of injury: C1-L2 and severity: AIS A-D (American Spinal Injury Association Impairment Scale). Time since injury (TSI) < 1 year, N = 25; > 1 year, N = 27. No serious adverse events occurred. Three participants dropped out following ankle swelling (overuse injury). Four participants sustained a Category II pressure ulcer at contact points with the device but completed the study and skin normalized. Training characteristics increased significantly for all subgroups. The number of participants with TSI < 1 year and gait function increased from 20 to 56% (P = 0.004) and 10MWT, TUG, BBS and LEMS results improved (P < 0.05). The number of participants with TSI > 1 year and gait function, increased from 41 to 44% and TUG and BBS results improved (P < 0.05). CONCLUSIONS: Exoskeleton training was generally safe and feasible in a heterogeneous sample of persons with SCI. Results indicate potential benefits on gait function and balance.

Can a prediction model combining self-reported symptoms, sociodemographic and clinical features serve as a reliable first screening method for sleep apnea syndrome in patients with stroke?

OBJECTIVE: To determine whether a prediction model combining self-reported symptoms, sociodemographic and clinical parameters could serve as a reliable first screening method in a step-by-step diagnostic approach to sleep apnea syndrome (SAS) in stroke rehabilitation. DESIGN: Retrospective study. SETTING: Rehabilitation center. PARTICIPANTS: Consecutive sample of patients with stroke (N=620) admitted between May 2007 and July 2012. Of these, 533 patients underwent SAS screening. In total, 438 patients met the inclusion and exclusion criteria. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: We administered an SAS questionnaire consisting of self-reported symptoms and sociodemographic and clinical parameters. We performed nocturnal oximetry to determine the oxygen desaturation index (ODI). We classified patients with an ODI ≥15 as having a high likelihood of SAS. We built a prediction model using backward multivariate logistic regression and evaluated diagnostic accuracy using receiver operating characteristic analysis. We calculated sensitivity, specificity, and predictive values for different probability cutoffs. RESULTS: Thirty-one percent of patients had a high likelihood of SAS. The prediction model consisted of the following variables: sex, age, body mass index, and self-reported apneas and falling asleep during daytime. The diagnostic accuracy was .76. Using a low probability cutoff (0.1), the model was very sensitive (95%) but not specific (21%). At a high cutoff (0.6), the specificity increased to 97%, but the sensitivity dropped to 24%. A cutoff of 0.3 yielded almost equal sensitivity and specificity of 72% and 69%, respectively. Depending on the cutoff, positive predictive values ranged from 35% to 75%. CONCLUSIONS: The prediction model shows acceptable diagnostic accuracy for a high likelihood of SAS. Therefore, we conclude that the prediction model can serve as a reasonable first screening method in a stepped diagnostic approach to SAS in stroke rehabilitation.

Cohort profile: Netherlands Longitudinal Study on Hearing (NL-SH).

PURPOSE: The Netherlands Longitudinal Study on Hearing (NL-SH) was set up to examine associations of hearing ability with psychosocial, work and health outcomes in working age adults. PARTICIPANTS: Inclusion started in 2006 and is ongoing. Currently the sample comprises 2800 adults with normal and impaired hearing, aged 18-70 years at inclusion. Five-year follow-up started in 2011, 10-year follow-up in 2016 and 15-year follow-up in 2021. All measurements are web-based. Participants perform a speech-in-noise recognition test to measure hearing ability and fill out questionnaires about their hearing status, hearing aid use, self-reported hearing disability and coping, work status and work-related outcomes (work performance, need for recovery), physical and psychosocial health (depression, anxiety, distress, somatisation, loneliness), healthcare usage, lifestyle (smoking, alcohol), and technology use. FINDINGS TO DATE: The NL-SH has shown the vast implications of reduced hearing ability for the quality of life and health of working-age adults. A selection of results published in 27 papers is presented. Age-related deterioration of hearing ability accelerates after the age of 50 years. Having a history of smoking is associated with a faster decline in hearing ability, but this relationship is not found for other cardiovascular risk factors. Poorer hearing ability is associated with increased distress, somatisation, depression and loneliness. Adults with impaired hearing ability are more likely to be unemployed or unfit for work, and need more time to recuperate from work effort. FUTURE PLANS: Participant data will be linked to a national database to enable research on the association between hearing ability and mortality. Linking to environmental exposure data will facilitate insight in relations between environmental factors, hearing ability and psychosocial outcomes. The unique breadth of the NL-SH data will also allow for further research on other functional problems, for instance, hearing ability and fall risk. TRIAL REGISTRATION NUMBER: NL12015.029.06.

Hearing ability in working life and its relationship with sick leave and self-reported work productivity.

OBJECTIVES: Reduced hearing ability has been shown to influence various aspects of daily life, such as communication, psychosocial functioning, and working life. The aim of this study is to examine the association between hearing ability in noise and both sick leave and self-reported work productivity. In addition, the relationship between hearing ability and perceived health-caused limitations at work is examined. METHODS: Data were collected at the baseline measurement of the Dutch "National Longitudinal Study on Hearing" and at each month during a subsequent period of 3 mo. Hearing ability was determined by means of the National Hearing Test, a speech-in-noise test over the Internet using digit triplets. The sample comprised 748 workers (385 with normal hearing ability and 363 with insufficient or poor hearing ability). RESULTS: Linear regression analyses revealed a significant adverse association between reduced hearing ability and self-reported absolute and differential productivity; for every dB signal-to-noise ratio (dB SNR) poorer hearing ability, self-rated absolute productivity for people experiencing little social support decreased by 0.054 points on a scale from 0 to 10 (b = -0.054; 95% confidence interval [CI] = -0.088 to -0.02). For people with less than three other chronic conditions, self-rated differential productivity also decreased significantly with decreasing hearing ability (no chronic conditions: b = -0.048 points/dB SNR on a scale from -10 to + 10, 95% CI = -0.094 to -0.001; one or two other chronic conditions: b = -0.035 points/dB SNR, 95% CI = -0.067 to -0.002). With adjustment for confounders, poorer hearing ability in noise furthermore significantly increased the odds for experiencing limitations (in the type or amount of work one could do) sometimes (odds ratio = 1.14; 95% CI = 1.07-1.21) and often to very often (odds ratio = 1.24; 95% CI = 1.05-1.45) in comparison with experiencing limitation seldom to never. A higher level of need for recovery among people with poorer hearing ability appeared to be one of the factors mediating the higher odds for sick leave of more than 5 days. CONCLUSION: Reduced hearing ability in noise was significantly associated with a lower self-reported absolute and differential productivity in specific cases. Also, poorer hearing increased the odds for experiencing health-caused limitations in the type or amount of work one can do. The significant relationship between hearing ability and sick leave, which was found when not adjusting for confounders, could partly be explained by a higher need for recovery among people with reduced hearing ability in noise.

Faecal Microbiota in Patients with Neurogenic Bowel Dysfunction and Spinal Cord Injury or Multiple Sclerosis-A Systematic Review.

BACKGROUND: Neurogenic bowel dysfunction (NBD) frequently occurs in patients with spinal cord injury (SCI) and multiple sclerosis (MS) with comparable symptoms and is often difficult to treat. It has been suggested the gut microbiota might influence the course of NBD. We systematically reviewed the literature on the composition of the gut microbiota in SCI and MS, and the possible role of neurogenic bowel function, diet and antibiotic use. METHODS: A systematic search was conducted in PubMed and Embase, which retrieved studies on the gut microbiota in SCI and MS. The Newcastle-Ottawa Quality Assessment Scale (NOS) was used to assess methodological quality. RESULTS: We retrieved fourteen papers (four on SCI, ten on MS), describing the results of a total of 479 patients. The number of patients per study varied from 13 to 89 with an average of 34. Thirteen papers were observational studies and one study was an intervention study. The studies were case control studies in which the gut microbiota composition was determined by 16S rRNA gene sequencing. The methodological quality of the studies was mostly rated to be moderate. Results of two studies suggested that alpha diversity in chronic SCI patients is lower compared to healthy controls (HC), whereas results from five studies suggest that the alpha diversity of MS patients is similar compared to healthy subjects. The taxonomic changes in MS and SCI studies are diverse. Most studies did not account for possible confounding by diet, antibiotic use and bowel function. CONCLUSION: Based on these 14 papers, we cannot draw strong conclusions on the composition of the gut microbiota in SCI and MS patients. Putatively, alpha diversity in chronic SCI patients may be lower compared to healthy controls, while in MS patients, alpha diversity may be similar or lower compared to healthy controls. Future studies should provide a more detailed description of clinical characteristics of participants and of diet, antibiotic use and bowel function in order to make valid inferences on changes in gut microbiota and the possible role of diet, antibiotic use and bowel function in those changes.

Comparing health care use and related costs between groups with and without hearing impairment.

This study aims to compare the use (and related costs) of different health care resources between groups of normally-hearing and hearing-impaired people. A distinction was made between hearing-related and other health care contacts. Data were collected at the baseline measurement of the national longitudinal study on hearing, and at each month during a subsequent period of six months. Hearing status was determined using an internet speech-in-noise test. The sample comprised 1295 normally-hearing and hearing-impaired subjects, aged 18-65 years. Adjusting for confounders, regression models showed that hearing-impaired respondents had significantly more contacts and higher costs for primary, secondary, and occupational care than normally-hearing respondents during the period under investigation. The differences were due to a larger number of health care contacts for which hearing impairment was the main motive to seek help. After excluding these contacts, the differences in health care use and costs between the groups were not significant. This suggests that besides hearing-related contacts, adults with hearing impairment do not make more use of health care resources than adults without hearing difficulties.

The association between hearing status and psychosocial health before the age of 70 years: results from an internet-based national survey on hearing.

OBJECTIVE: There is a substantial lack of knowledge of the impact of reduced hearing on psychosocial functioning in adults younger than 70 yr. The aim of this study was to examine the association between hearing status and psychosocial health in adults aged between 18 and 70 yr. DESIGN: This was a cross-sectional cohort study. Baseline data of the National Longitudinal Study on Hearing are analyzed using regression models. The cohort consisted of 1511 participants. Hearing status was determined using the National Hearing test, a recently launched speech-in-noise screening test over the Internet. We assessed self-reported psychosocial health using a set of online questionnaires. RESULTS: Adjusting for confounding variables, significant adverse associations between hearing status and distress, somatization, depression, and loneliness are found. For every decibel signal to noise ratio (dB SNR) reduction of hearing status, both the distress and somatization scores increased by 2% [distress: b = 0.02, 95% confidence interval (CI) = 0.00 to 0.03, p = 0.03; somatization: b = 0.02, 95% CI = 0.01 to 0.04, p < 0.001]. The odds for developing moderate or severe depression increase by 5% for every dB SNR reduction in hearing (odds ratio = 1.05, 95% CI = 1.00 to 1.09, p = 0.03). The odds for developing severe or very severe loneliness significantly increase by 7% for every dB SNR reduction in hearing (odds ratio = 1.07, 95% CI = 1.02 to 1.12, p = 0.004). Different age groups exhibit different associations between hearing status and psychosocial health, with loneliness being an issue particularly in the youngest age group (18 to 30 yr). In the group of middle-aged adults (40 to 50 yr), the number of significant associations is highest. CONCLUSIONS: Hearing status is negatively associated with higher distress, depression, somatization, and loneliness in young and middle-aged adults. The associations are different in different age groups. The findings underline the need to seriously address the adverse effects of limited hearing among young and middle-aged adults both in future research and in clinical practice.

Hearing status, need for recovery after work, and psychosocial work characteristics: results from an internet-based national survey on hearing.

The main aim of the study is to address the relationship between hearing status and need for recovery. In addition, the role of hearing status in the relationship between psychosocial work characteristics (i.e. job demands and job control) and need for recovery was assessed. The sample comprised 925 normally-hearing and hearing-impaired working adults (aged 18-65 years) participating in the National Longitudinal Study on Hearing. Hearing status was determined using the national hearing (speech-in-noise) test over the internet. Psychosocial work characteristics and need for recovery were assessed using the job content questionnaire and the Dutch questionnaire on the experience and assessment of work. Regression models revealed a significant association between hearing status and need for recovery after work, poorer hearing leading to an increasing need for recovery. Additionally, poorer hearing led to a higher odds for risky levels of need for recovery. Hearing status did not influence the significant relationship between psychosocial work characteristics (i.e. job demand and job control) and need for recovery after work. Implications for clinical practice, such as the necessity of having adequate enablement programs for this specific group of patients, are discussed.

Implementation of a Standardized Dataset for Collecting Information on Patients With Spinal Cord Injury.

Background: Over the last decade, the International Spinal Cord Injury Data Sets project developed a number of International Spinal Cord Injury Data Sets (ISCIDS) that can be used to collect standardized information on patients with SCI. Objective and Methods: The aim of this article is to describe the process of translating the ISCIDS into Dutch and reaching consensus on a Dutch National SCI Data Set (NDD). The interrater reliability of the NDD and implementation of the NDD at eight rehabilitation centers with a specialty in rehabilitation after SCI in the Netherlands are described. Results: NDD was implemented successfully at all eight centers. Some adaptations were made to the ISCIDS, especially to the core data set. The reliability coefficients of the NDD items were at least sufficient (mean kappa per data set ranged between .68 and .91), and mean agreement per data set ranged from 66% to 97%. Experiences from the participating centers were mainly positive as well. The main obstacle for use was thought to be the absence of a link between the local patient files and the national database, which necessitates double data entry. Conclusion: Although the results on interrater reliability are based on a small sample size and the assessment situation is different from the normal clinical situation, this study showed the NDD to be a useful instrument to collect standardized information on patients with SCI in the Netherlands. In the future, a connection between systems or another way to centrally collect the data is recommended to prevent double data entry and to guarantee continuation of administration of the NDD.

Progress of the Dutch Spinal Cord Injury Database: Completeness of Database and Profile of Patients Admitted for Inpatient Rehabilitation in 2015.

Background: In the Dutch International Spinal Cord Injury (SCI) Data Sets project, we translated all International SCI Data Sets available in 2012 and created a Dutch SCI Database (NDD). Objective: To describe the number of included patients and completeness of the NDD, and to use the NDD to provide a profile of people with traumatic SCI (T-SCI) and non-traumatic SCI (NT-SCI) in the Netherlands. Methods: The NDD includes patients admitted for their first inpatient rehabilitation after onset of SCI to 1 of the 8 rehabilitation centers with a specialty in SCI rehabilitation in the Netherlands. Data of patients admitted in 2015 were analyzed. Results: Data for 424 patients were available at admission; for 310 of these patients (73.1%), discharge data were available. No significant differences were found between patients with and without data at discharge. Data were nearly complete (>90%) for lower urinary tract, bowel, pain, and skin. Data on sexual function has the lowest completion rate. Complete neurological and functional data were available for 41.7% and 38%, respectively. Most patients were male (63.4%), had NT-SCI (65.5%), and had incomplete SCI (58.4% D). Patients with T-SCI differed from patients with NT-SCI on most characteristics, and they stayed considerably longer in the rehabilitation center (112 days vs 65 days, p < .001). Place of discharge was not different between both groups. Conclusion: With the NDD, we collect important data on the majority of Dutch SCI patients, although much work needs to be done to improve the completeness of the data collection.

Exoskeleton gait training after spinal cord injury: An exploratory study on secondary health conditions.

OBJECTIVE: To explore changes in pain, spasticity, range of motion, activities of daily living, bowel and lower urinary tract function and quality of life of individuals with spinal cord injury following robotic exoskeleton gait training. DESIGN: Prospective, observational, open-label multicentre study. METHODS: Three training sessions per week for 8 weeks using an Ekso™ GT robotic exoskeleton (EKSO Bionics). Included were individuals with recent (<1 year) or chronic (>1 year) injury, paraplegia and tetraplegia, complete and incomplete injury, men and women. RESULTS: Fifty-two participants completed the training protocol. Pain was reported by 52% of participants during the week prior to training and 17% during training, but no change occurred longitudinally. Spasticity decreased after a training session compared with before the training session (p <0.001), but not longitudinally. Chronically injured participants increased Spinal Cord Independence Measure (SCIM III) from 73 to 74 (p = 0.008) and improved life satisfaction (p = 0.036) over 8 weeks of training. Recently injured participants increased SCIM III from 62 to 70 (p < 0.001), but no significant change occurred in life satisfaction. Range of motion, bowel and lower urinary function did not change over time. CONCLUSION: Training seemed not to provoke new pain. Spasticity decreased after a single training session. SCIM III and quality of life increased longitudinally for subsets of participants.

Predictors of physical independence at discharge after stroke rehabilitation in a Dutch population.

The aim of this study was to identify predictors, available at admission, of physical independence at discharge from inpatient rehabilitation. Secondary aims were to identify predictors of functional gain and length of stay (LOS). We included 1310 adult stroke patients who were admitted for inpatient rehabilitation in five Dutch rehabilitation centres. Data on the Utrecht Scale for Evaluation of Clinical Rehabilitation at admission and discharge (physical and cognitive independence, mood, pain and fatigue), age, sex and in a subsample stroke characteristics as well were collected. A prediction model was created using random coefficient analysis. None of the stroke characteristics were independently associated with physical independence or functional gain at discharge, or LOS. Higher physical and cognitive independence scores and severe pain at admission were predictors of higher physical independence scores at discharge. Furthermore, lower physical independence scores, higher cognitive independence scores, less pain at admission and younger age predicted more functional gain. Finally, lower physical and cognitive independence scores at admission and younger age predicted longer LOS. Physical independence at admission was the most robust predictor for rehabilitation outcome in a Dutch rehabilitation setting. To a lesser extent, age, cognitive independence and pain predicted rehabilitation outcome after stroke. Treatment of cognition and pain should be taken into account during rehabilitation. Further work needs to be carried out to establish whether focusing on these factors improves outcome after rehabilitation.
