Impact of pressure ulcers on individuals living with a spinal cord injury

Mixed-variable graphical modeling framework towards risk prediction of hospital-acquired pressure injury in spinal cord injury individuals

Developing machine learning (ML) methods for healthcare predictive modeling requires absolute explainability and transparency to build trust and accountability. Graphical models (GM) are key tools for this but face challenges like small sample sizes, mixed variables, and latent confounders. This paper presents a novel learning framework addressing these challenges by integrating latent variables using fast causal inference (FCI), accommodating mixed variables with predictive permutation conditional independence tests (PPCIT), and employing a systematic graphical embedding approach leveraging expert knowledge. This method ensures a transparent model structure and an explainable feature selection and modeling approach, achieving competitive prediction performance. For real-world validation, data of hospital-acquired pressure injuries (HAPI) among individuals with spinal cord injury (SCI) were used, where the approach achieved a balanced accuracy of 0.941 and an AUC of 0.983, outperforming most benchmarks. The PPCIT method also demonstrated superior accuracy and scalability over other benchmarks in causal discovery validation on synthetic datasets that closely resemble our real dataset. This holistic framework effectively addresses the challenges of mixed variables and explainable predictive modeling for disease onset, which is crucial for enabling transparency and interpretability in ML-based healthcare.

Health consequences associated with poor diet and nutrition in persons with spinal cord injuries and disorders

PURPOSE

To describe health consequences associated with poor diet in persons with spinal cord injuries and disorders (SCI/D).

MATERIALS/METHODS

Descriptive qualitative design using in-depth interviews with SCI/D health providers. Audio-recorded and transcribed verbatim transcripts were coded and analyzed using thematic analysis.

RESULTS

Participants (n = 12) were from 11 nationwide VA hospitals. Participants were male (75%), white (67%), 26-49 years of age, and most were dietitians (75%) and physiatrists (17%). Seven key themes identified consequences associated with poor diet in persons with SCI/D, including (1) Weight gain and body composition changes, (2) cardiometabolic conditions, (3) bowel dysfunction, (4) pressure injuries/wounds, (5) other SCI/D secondary conditions/complications (renal/kidney; immune function/susceptibility to infections; autonomic dysreflexia; bone health/osteoporosis; pain), (6) physical fatigue, and (7) poor mental health.

CONCLUSIONS

Excess weight, cardiometabolic conditions, SCI/D secondary conditions/complications (e.g., bowel dysfunction, pressure injuries), and poor mental health were identified as health consequences of inadequate nutrition. Health providers should make individuals with SCI/D aware of the risks and health consequences to incentivize healthier dietary behaviors. Efforts to identify nutrition shortcomings and to develop interventions and tailored care plans are needed to improve a myriad of health consequences due to poor diet and nutrition in persons with SCI/D.

Baseline health-related self-efficacy for individuals following stroke, traumatic brain injury, and spinal cord injury prior to enrollment in a weight-loss intervention

PURPOSE

To examine health-related self-efficacy for individuals following acquired brain or spinal cord injury prior to enrollment in a weight-loss intervention and associations with demographics, injury characteristics, and additional physiologic variables.

MATERIALS AND METHODS

Cross-sectional analysis of baseline data for community-dwelling adults following stroke (CVA), traumatic brain injury (TBI), or spinal cord injury (SCI) across three disability-adapted weight-loss interventions.

RESULTS

Overall results suggest a significant difference between injury type and self-efficacy as measured by the Self Rated Abilities for Health Practices (SRAHP) scale. On average, individuals with SCI had the lowest overall perceived self-efficacy of the three groups (11.2-unit difference; (CI: -17.4, -5.0), followed by those with TBI (9.5-unit difference; (CI: -16.7, -2.4). There were also differences between groups in age, number of household members, time since injury, sex, race, marital status, physiological measures, and employment status.

CONCLUSIONS

Results suggest that individuals with different disabilities following neurological injuries have different baseline perceptions in their ability to eat a healthy diet and exercise regularly. Health interventions should be tailored for these groups based on disability-specific barriers and should include components to enhance health-related self-efficacy to address weight management among these populations.IMPLICATIONS FOR REHABILITATIONEvidence suggests that health-related self-efficacy may differ following different injury types and level of disability may impact one's ability to maintain health-related behaviorsResults suggest that individuals with a spinal cord injury may have different baseline perceptions of self-efficacy related to their ability to eat a healthy diet and exercise regularly compared to those with a traumatic brain injury or stroke.Health interventions should be tailored to encompass disability-specific barriers which may impact an individual's health-related self-efficacy.

Reducing pressure with the goal of improving outcomes: a retrospective chart review of cushion evaluations and recommendations at one seating clinic

PURPOSE

To describe the current seating recommendations made by a seating clinic for wheelchair users who presented with a Pressure Injury (PrI) or history of PrI.

METHODS

Retrospective review of electronic medical records of 133 adults who used a wheelchair as their primary means of mobility who had a cushion evaluation during which interface pressure mapping data was documented.

RESULTS

Clinicians adjusted 71% of participants' wheelchair cushions, including 49% who received a new cushion, and 37% of participants' wheelchairs. The most common adjustments besides receiving a new cushion were: addition of an underlay, adjusting the inflation of a cushion, and adjustments to the foot or back support of the wheelchair. Forty-five participants only received adjustments (i.e. no new cushion), while 23 participants only received education and feedback rather than equipment modifications. Those 23 participants had significantly lower Peak Pressure Index (PPI) than those who received equipment modifications (mean [95% CI] 76.7 [59.1, 94.3] versus 111.6 [102.1, 121.2] respectively, p = 0.001). The PPI was reduced by an average of 22.5 mmHg from the initial to final seating system amongst those who received modifications ([13.9-31.0], p<.001).

CONCLUSIONS

The seating clinicians considered interface pressure mapping in their decision-making and effectively reduced interface pressures with their interventions. Cushion replacement is important when someone presents with a PrI. However, adjusting an existing wheelchair cushion and/or seating system provides important additions and alternatives to consider for reducing interface pressure. There is also a role for education about proper use of equipment, weight shifts, and alternate seating surfaces.

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

BACKGROUND

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

OBJECTIVE

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

DESIGN

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

PARTICIPANTS

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

RESULTS

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

CONCLUSIONS

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

Sacral Ulcer Development Risk Among Older Adult Patients in North Texas Rehabilitation Hospitals: Role of Comorbidities, Lifestyle, and Personal Factors

PURPOSE

Sacral ulcers are a serious mortality risk for older adults; thus, we aimed to determine sacral ulcer risk factors among older adults who were recently admitted to rehabilitation hospitals.

METHOD

We conducted a retrospective cohort study using the Texas Inpatient Discharge database (2021). The study included 1,290 rehabilitation hospital patients aged ≥60 years diagnosed with sacral ulcers. The control group comprised 37,626 rehabilitation hospital patients aged ≥60 years without sacral ulcers. Binary logistic regression was used to identify risks for sacral ulcer development adjusting for patient demographics, insurance type, and lifestyle.

RESULTS

Comorbidities of dementia, Parkinson's disease, type 2 diabetes, and cardiac dysrhythmias were significantly associated with increased risk of sacral ulcers. Longer length of stay, Medicare, and Medicare HMO were also associated with sacral ulcers. Demographically, older age, male sex, identifying as African American, and having malnutrition all had a 50% increased prevalence of sacral ulcers.

CONCLUSION

Findings indicate a need to proactively treat chronic comorbidities in vulnerable populations to reduce their possible risk for hospital-acquired infections and excess mortality from sacral ulcers. [Journal of Gerontological Nursing, 50(2), 32-41.].

Physiological and nutrition-related challenges as perceived by spinal cord-injured endurance hand cyclists

This study explored the perceptions of spinal cord-injured (SCI) endurance hand cyclists regarding their physiological and nutrition-related challenges and the perceived impact of these challenges on nutritional intake and exercise capacity. This was an interpretive qualitative descriptive study in which semi-structured interviews were conducted with 12 adult South African national-level SCI endurance hand cyclists. Thematic analysis was used to explore perceptions regarding physiological and nutrition-related challenges and the impact thereof on nutritional practices and exercise capacity. Four themes emerged from the interviews: (i) physiological challenges experienced, (ii) nutrition-related challenges experienced, (iii) changes in nutritional practices, and (iv) compromised exercise capacity. The SCI endurance hand cyclists reported a number of physiological and nutrition-related challenges. Bowel and bladder challenges, limited hand function, muscle spasms, thermoregulatory challenges, pressure sores, menstrual periods, and low iron levels/anaemia were perceived to predominantly impact food and fluid intake (restrict intake) and compromise exercise capacity. This information can assist to devise tailored guidelines aimed to optimise fluid intake, overcome bladder challenges and ensure adequate nutritional intake in light of limited hand function.

The relationship between in-seat movement and pressure ulcers in wheelchair users with SCI/D

OBJECTIVE

To identify parameters that are associated with time at pressure, are most related to pressure ulcer outcomes, and that may be used to influence pressure ulcer (PrU) outcomes in future intervention studies.

DESIGN

Analysis used datasets from cross-sectional and longitudinal observational studies. Wheelchair-usage and in-seat metrics thresholds were optimized to differentiate individuals in PrU or No PrU groups. Logistic regression identified the demographics and in-seat activity metrics that impacted PrU outcomes.

SETTING

General Community.

PARTICIPANTS

Fifty individuals with spinal cord injuries and/or disorders (SCI/D) who use a wheelchair as their primary mobility device. 22 subjects were within the first year following injury and 28 had been using a wheelchair for over 2 years. Twenty-one participants reported PrU outcomes.

INTERVENTIONS

Not applicable.

OUTCOME MEASURES

Time in chair, pressure relief frequency, weight shift frequency, percentage of seated time that the subject is active (CoP Percent Active), frequency of in-seat movement, unloading event frequency, maximum time between events, and number of transfers.

RESULTS

Optimal cutoff thresholds for the most significant in-seat movement metrics included: unloading event frequency of 3.1 times per hour (OR 0.353, 95% CI [0.110, 1.137]), maximum time between events of 155.4 min (OR 2.888, 95% CI [0.886, 9.413]), and CoP Percent Active of 2.6% (OR 0.221, 95% CI [0.063, 0.767]). When individuals were more active than these cutoffs, significantly more individuals were in the no pressure ulcer group. In predictive modeling, CoP Percent Active was the in-seat movement metric that significantly predicted PrU outcomes. The model was improved by adding age, occupation, and injury completeness.

CONCLUSION

Of the 4 significant predictors in the model, only CoP Percent Active was modifiable. Therefore, an opportunity exists to design approaches to modify behavior. However, the results illustrate that the key to preventative movement may be through functional movement as opposed to scheduled, routine pressure reliefs.

Exercise prescription for persons with spinal cord injury: a review of physiological considerations and evidence-based guidelines

Persons with spinal cord injury (SCI) experience gains in fitness, physical and mental health from regular participation in exercise and physical activity. Due to changes in physiological function of the cardiovascular, nervous, and muscular systems, general population physical activity guidelines and traditional exercise prescription methods are not appropriate for the SCI population. Exercise guidelines specific to persons with SCI recommend progressive training beginning at 20 min of moderate to vigorous intensity aerobic exercise twice per week transitioning to 30 min three times per week, with strength training of the major muscle groups two times per week. These population-specific guidelines were designed considering the substantial barriers to physical activity for persons with SCI and can be used to frame an individual exercise prescription. Rating of perceived exertion (i.e., perceptually regulated exercise) is a practical way to indicate moderate to vigorous intensity exercise in community settings. Adapted exercise modes include arm cycle ergometry, hybrid arm-leg cycling, and recumbent elliptical equipment. Body weight-supported treadmill training and other rehabilitation modalities may improve some aspects of health and fitness for people with SCI if completed at sufficient intensity. Disability-specific community programs offer beneficial opportunities for persons with SCI to experience quality exercise opportunities but are not universally available.

Pressure Injury Data Reconciliation in a Randomized Controlled Trial

OBJECTIVE

To advance pressure injury (PrI) research in individuals with spinal cord injury (SCI) by describing lessons learned and recommendations for future research, ultimately promoting PrI prevention and more effective wound care. This paper describes the detailed procedures undertaken to collect and reconcile PrI data and summarizes the types of discrepancies identified.

DESIGN

Secondary analyses of PrI data collected between 2009 and 2014 in a randomized controlled trial (parent study).

SETTING

Participants in the parent study were recruited from a large rehabilitation center in the Los Angeles area that serves primarily individuals with limited resources.

PARTICIPANTS

232 participants with SCI and a history of 1 or more medically serious PrI (MSPrI) in the previous 5 years.

INTERVENTIONS

Participants in the parent study were randomized to a 12-month PrI prevention intervention led by an occupational therapist, or to usual care.

MAIN OUTCOME MEASURES

Relations among PrI characteristics, data sources (phone interviews, skin checks, paper and electronic medical records [MRs]), and treatment condition, and sensitivity of 6 different data sources in detecting MSPrIs.

RESULTS

The majority (62%) of MSPrIs were in the pelvic region. MRs detected 82% of the MSPrIs overall, making it the most sensitive data source, and scheduled skin checks were the second-most sensitive data source, finding 37% of the MSPrIs.

CONCLUSIONS

MR review is the preferred method for ascertaining MSPrIs in clinical trials of interventions designed to reduce the incidence of these injuries. When multiple sources of information are used, careful reconciliation of reports is necessary to ensure accuracy.

Repositioning for pressure injury prevention in adults: a commentary on a Cochrane review

Repositioning is regarded as an important intervention to prevent the development of pressure injuries in patients who are immobile. However, there is uncertainty as to the optimal regimen in terms of frequency and method of repositioning. This commentary summarises and critically appraises a Cochrane systematic review that assessed the clinical and costeffectiveness of different repositioning regimens on the prevention of pressure injuries in adults in any setting.

A longitudinal analysis of resting energy expenditure and body composition in people with spinal cord injury undergoing surgical repair of pressure injuries: a pilot study

BACKGROUND

Data informing energy needs of people with spinal cord injury (SCI) and pressure injuries are scarce, the impact of surgical repair unknown, and the role of body composition in healing unexplored. The study aims were to investigate resting energy expenditure (REE) over the course of pressure injury surgical repair, compare with available energy prediction equations, and explore associations between body composition and wound healing.

METHODS

Indirect calorimetry measured REE pre-surgery, post-surgery, at suture removal and hospital discharge. A clinically significant change was defined as +/-10% difference from pre-surgery. Eight SCI-specific energy prediction equations were compared to pre-surgery REE. Wound breakdown (Yes/No), weight, waist circumference (WC), and body composition (fat mass [FM], fat-free mass [FFM], bioimpedance spectroscopy) were measured.

RESULTS

Twenty people underwent pressure injury surgical repair (95% male, mean age 56 ± 12 years, 70% paraplegia). Between pre-surgery and discharge, mean REE increased (+118 kcal/d, p = 0.005), but with <10% change at any timepoint. An energy prediction equation incorporating FFM showed greatest agreement (r_c = 0.779, 95% CI: 0.437, 0.924). Those with wound breakdown (65%) had a higher weight (12.7 kg, 95% CI: -4.0, 29.3), WC (17.8 cm, 95% CI: -5.1, 40.7), and FM % (36.0% [IQR 31.8, 40.2] vs 26.0% [IQR 15.6, 41.3]) than those without wound breakdown, although statistical significance was not reached.

CONCLUSION

The presence of pressure injuries and subsequent surgical repair did not impact REE and energy prediction equations incorporating FFM performed best. While not statistically significant, clinically important differences in body composition were observed in those with wound breakdown.

The healthcare needs and general practice utilization of people with acquired neurological disability and complex needs: A scoping review

BACKGROUND

For people with acquired neurological disabilities and complex needs, general practitioners (GPs) play an important role in health management and early intervention for the prevention of comorbidities and health complications. People with disability are a vulnerable group who need and have the right to, quality general practice services. It is therefore important to understand the health needs and service use of this group. The aim of this review was to identify the healthcare needs and general practice utilization of people with acquired neurological disabilities and complex needs.

METHODS

A scoping review methodological framework was utilized. Six databases (MEDLINE, PsycInfo, CINAHL, Scopus, Embase and the Cochrane Library) were searched. Articles were included if they reported on general practice service utilization of people with acquired neurological disabilities and complex needs aged between 18 and 65. Articles were required to be peer-reviewed, written in English and published between 2010 and 2021.

RESULTS

Thirty-one articles were included in the review. Studies originated from Canada (9), the United States (8), Australia (4), Switzerland (4), the United Kingdom (2), England (1), Norway (1), France (1) and Denmark (1). For many people, GPs were the main healthcare provider. People with disability consult multiple healthcare providers and navigate complex healthcare systems. Commonly presented healthcare needs were bladder, bowel and skin problems, pain and chronic pain, medication needs and mental health concerns.

CONCLUSIONS

People with acquired neurological disabilities and complex needs were vulnerable to receiving suboptimal healthcare. The literature highlighted issues regarding the accessibility of services, the fragmentation of health services and inadequate preventative care. GPs were challenged to offer adequate disability-related expertise and to meet the mental health needs of people with disability within time constraints.

PATIENT AND PUBLIC INVOLVEMENT

This manuscript was prepared in collaboration with a GP, who is one of the authors. A person with lived experience of acquired neurological disability was engaged to check the alignment of the findings with their personal experience and provide feedback.

Determining Incidence and Risk Factors of Pressure Injury After Orthopaedic Surgery in Children and Adolescents With Neuromuscular Complex Chronic Conditions

BACKGROUND

Pressure injuries are serious yet often preventable alterations in skin integrity prevalent in orthopaedics, especially in pediatric patients with neuromuscular complex chronic conditions (NCCC). The aims of this study were to (1) estimate incidence of pressure injury in children with NCCC after orthopaedic surgery; (2) determine risk factors for pressure injury development; and (3) describe severity and location of pressure injuries.

METHODS

Children and adolescents (<22 y old) with NCCC who underwent orthopaedic surgery at a single tertiary-care children's hospital between 2016 and 2020 were retrospectively identified. A matched case-control design was used to match patients who developed a pressure injury within 1.5 months after surgery to subjects who did not develop a pressure injury using a 1:1 matching based on neuromuscular diagnosis, age, sex, and type of surgery. Patient characteristics, comorbidities, pressure injury characteristics, and a pressure injury risk assessment score utilizing the Braden QD scale were compared across pressure injury groups.

RESULTS

Of 564 children with NCCC who underwent orthopaedic surgery, 43 (7.6%) developed a postoperative pressure injury. Pressure injuries were primarily located on the heel, followed by sacral/groin/buttocks, then knee. The most common diagnosis was cerebral palsy with associated neuromuscular scoliosis, and hip reconstruction was the most common surgical procedure. The pressure injury cohort had significantly more patients who were non-ambulatory (GMFCS IV/V), with a seizure disorder, g-tube, nonverbal status, wheelchair usage, and had additional medical devices. Median Braden QD risk score was higher in the injury cohort and a cutoff ≥12 was optimal for predicting pressure injury development.

CONCLUSIONS

Pressure injuries after orthopaedic surgery are not uncommon in children with NCCC. The entire care team should be aware of additional risk factors associated with pressure injury development, including the diagnosis of cerebral palsy with neuromuscular scoliosis, seizure disorder, nonverbal status, g-tube, and the presence of multiple medical devices. Implementation of evidence-based pressure injury prevention guidelines on identified high-risk children with NCCC may reduce pressure injury risk and improve the postoperative course.

"Platelet-Rich Fibrin Membrane-as a novel biomaterial for pressure injury healing in a person with spinal cord injury: A case report"

INTRODUCTION

Pressure injury (PI) impacts the quality of life, and socioeconomic and psychological well-being negatively in persons with Spinal Cord Injury (SCI). Autologous Platelet Rich Plasma (PRP) and Platelet Rich Fibrin (PRF) showed promising roles in wound healing. PRF is considered a second-generation PRP, contains more growth factors and is more biocompatible than PRP. It possesses an additional favourable impact on wound healing due to its three-dimensional fibrin architecture, and antimicrobial property. There are no studies on PRF membrane use for PI healing in SCI.

CASE PRESENTATION

A 25-year-old male with operated traumatic T10 American Spinal Injury Association Impairment Scale grade A paraplegia with neurogenic bowel, and bladder and a stage II PI over the left greater trochanter, was admitted for inpatient rehabilitation. The chronic non-healing PI which did not show any improvement following normal saline (0.9%) dressing for the past 3 months, was treated with autologous PRF membrane weekly for four weeks. The PI healed completely and no adverse events were noted. Weekly total scores of the Spinal Cord Impairment Pressure Ulcer Monitoring Tool and Pressure Ulcer Scale for Healing were 6, 6, 5, 2, 0 and 12, 10, 10, 3, and 0 respectively.

DISCUSSION

To the best of our knowledge, this is the first case report on the healing of PI in SCI with the use of PRF. This novel biomaterial is a safe and effective promising agent for PI management in SCI. But further randomized trials are needed to establish stronger evidence regarding feasibility and effectiveness.

The patient behind the wound assessment and plan

OBJECTIVE

Hard-to-heal wounds are a common problem, worsened by ageing, and the increased prevalence of diabetes and morbid obesity. The provider-patient relationship has undergone a transformation, from a paternalistic to a mutual participation model, in which 'the physician tries to enter the patient's world to see the illness through the patient's eyes'. The indepth assessment of the impact of psychosocial, physical issues and provider-patient dynamics is crucial to wound healing and patient wellbeing. It can customise future treatment including physical therapy, psychological and social interventions to improve outcomes.

METHOD

A new health-related quality of life instrument (HRQOL) proposal based on a survey consisting of 20 questions was completed by patients as a pilot project. The psychosocial, physical and provider-patient dynamics were evaluated. A total wound impact score (WIs) was tabulated, ranging from 20-80 points. A wound assessment and plan (PBW-AP) was created.

RESULTS

In our sample of 25 patients, 75% experienced a moderate WIs (50-69) and 5% experienced a severe WIs (31-49). Feeling angry about having a wound was reported by 40% of patients. A majority of patients (60%) thought about their wounds >1 hour per day. Importantly, 24% answered that their primary care physicians never mentioned their wounds.

CONCLUSION

It is important for all physicians taking care of patients with hard-to-heal wounds to see 'the patient behind the wound'. The PBW-AP algorithm is an individualised, multidisciplinary assessment and intervention based on a WIs. It is designed not only to identify but also to tackle psychosocial, physical, and provider-patient issues, to improve overall quality of life, patient satisfaction and clinical outcomes. Based on the results, the PBW-AP algorithm was designed to be used at initial and subsequent visits as a roadmap for problem identification and intervention.

Encouraging People with Spinal Cord Injury to Take Part in Physical Activity in the COVID-19 Epidemic through the mHealth ParaSportAPP

BACKGROUND

Although mHealth tools have great potential for health interventions, few experimental studies report on their use by people with spinal cord injuries in physical activity.

OBJECTIVE

The main objective of this study was to analyze the effect of the ParaSportAPP on different physical and psychological variables in people with paraplegia.

METHODS

Fourteen of these subjects made up the final sample. All the participants performed two pre-tests (control period) and a post-test with 8 months between the evaluations (COVID-19 broke out between pre-test 2 and the post-test). The ParaSportAPP was installed on their smartphones when they performed pre-test 2. The same tests were performed in the same order in all the evaluations: (i) the questionnaires PASIPD, HADS, RS-25; SCIM III and AQoL-8D, (ii) respiratory muscle strength, (iii) spirometry and (iv) cardiopulmonary exercise test.

RESULTS

The results showed no differences in any of the variables studied between the measurement times.

CONCLUSIONS

Although none of the variables experienced improvements, the ParaSportAPP mobile application was able to lessen the impact of the pandemic on the variables studied.

Effect of Tilt-in-Space and Reclining Angles of Wheelchairs on Normal Force and Shear Force in the Gluteal Region

Healthcare workers need to educate patients regarding proper sitting positions to prevent pressure injuries in the elderly and disabled. The purpose of this study was to investigate the differences in normal and shear force in the gluteal region using the combination of tilt-in-space and reclining functions of wheelchairs. Twelve healthy subjects were recruited. Protocols for 15 wheelchair tilt-in-space and reclining angles, including three reclining angles (0°, 10°, and 20°) and five tilt-in-space (0°, 5°, 10°, 15°, and 20°), were randomly assigned. To measure the amount of normal and shear force applied to the gluteal region while sitting on a wheelchair, a force plate was placed on the seat to measure the seat reaction force. For statistical analysis, a two-factor analysis of variance, with tilt-in-space and reclining, was performed for each normal and shear force. The normal force showed a significant decrease with increased reclining angle. For the shear force combined with sagittal and lateral components, the 10° tilt-in-space showed a significant decrease compared to other conditions. The combination of 20° reclining and 10° tilt-in-space angles may decrease both normal and shear force in the gluteal region while sitting. These findings may help wheelchair-dependent individuals avoid pressure injuries.

Team Approach: The Management of Adolescents and Adults with Scoliosis and Spina Bifida

»

Globally, the prevalence of myelomeningocele, the most common subtype of spina bifida, is 0.2 to 6.5 per 1,000 live births. In the U.S., adults account for >67% of the overall population with spina bifida.

»

With an estimated prevalence of up to 50%, scoliosis is one of the most common and severe orthopaedic conditions in patients with myelomeningocele.

»

The variable effects that scoliosis can have on an individual, the comorbidities associated with progressive scoliosis, and the risks associated with spine surgery call for a strong partnership and care coordination between medical and surgical teams to deliver a patient-centered approach.

»

A coordinated, structured, planned, and incremental team approach can help individuals achieve the overall goals of functionality and independence, as well as successful transition to adulthood.

»

Teams should consider a patient's social determinants of health (e.g., poverty or language barriers) and the effect of scoliosis on quality of life before proceeding with spinal deformity correction.

Risk Factors and Consequences of Lower Extremity Fracture Nonunions in Veterans With Spinal Cord Injury

We used Veterans Health Administration (VHA) national administrative data files to identify a cohort (fiscal years 2005–2014) of veterans with spinal cord injuries and disorders (SCID) to determine risk factors for and consequences of lower extremity fracture nonunions. Odds ratios (OR) for fracture nonunion were computed using multivariable‐adjusted logistic regression models. We identified three risk factors for nonunion: (i) older age (OR = 2.29; 95% confidence interval [CI] 1.21–4.33), (ii) longer duration of SCID (OR = 1.02; 95% CI 1.00–1.04), and (iii) fracture site (distal femur), with OR (comparison distal femur) including distal tibia/fibula (OR = 0.14; 95% CI 0.09–0.24), proximal tibia/fibula (OR = 0.19; 95% CI 0.09–0.38), proximal femur (OR = 0.10; 95% CI 0.04–0.21), and hip (OR = 0.13; 95% CI 0.07–0.26). Nonunions resulted in multiple complications, with upwards of 1/3 developing a pressure injury, 13% osteomyelitis, and almost 25% requiring a subsequent amputation. Our data have identified a high‐risk population for fracture nonunion of older veterans with a long duration of SCID who sustain a distal femur fracture. In view of the serious complications of these nonunions, targeted interventions in these high‐risk individuals who have any signs of delayed union should be considered. © 2021 The Authors.

Exploring the first pressure injury and characteristics of subsequent pressure injury accrual following spinal cord injury

Context/Objective: Clinicians have guidance on prevention and treatment of pressure injuries, but little is known regarding characteristics of patients who develop additional pressure injuries. Thus, our objective was to explore the first pressure injury and characteristics of individuals who develop subsequent pressure injuries during acute care and inpatient rehabilitation following spinal cord injury.Design: Secondary analysis of longitudinal data from a cohort of adults following initial traumatic spinal cord injury.Setting: Urban acute care hospital and inpatient rehabilitation facilities.Participants: A convenience sample of adults (n = 38) who developed at least one pressure injury during acute care and inpatient rehabilitation.Interventions: Not applicable.Outcome Measures: The primary outcomes were number of additional pressure injuries and stage of care during which they occurred, prior to community discharge.Results: A covariate-adjusted model revealed that participants with ASIA D injury had a 67% decrease in the rate of additional pressure injury incidence compared to participants with ASIA A injury (Rate Ratio = .33, 95% CI [0.13, 0.88]). The severity of the first pressure injury had no significant association with subsequent pressure injury incidence (P = .10).Conclusion: These findings indicated that individuals with greater sensory and motor loss had an increased risk of developing additional pressure injuries compared to individuals with less impairment. These results are meaningful for stakeholders interested in understanding factors associated with developing subsequent pressure injuries during the index rehabilitation stay and provide a foundation for future research in this area.

Quality of life: Guidelines for the care of people with spina bifida

Quality of Life (QOL) and Health-Related Quality of Life (HRQOL) are important concepts across the life span for those with spina bifida (SB). This article discusses the SB Quality of Life Healthcare Guidelines from the 2018 Spina Bifida Association's Fourth Edition of the Guidelines for the Care of People with Spina Bifida. The focus of these QOL Guidelines was to summarize the evidence and expert opinions on how to mitigate factors that negatively impact QOL/HRQOL or enhance the factors positively related to QOL/HRQOL, the measurement of QOL/HRQOL and the gaps that need to be addressed in future research.

Pedicled Chimeric Perforator Flap Based on Inferior Gluteal Vessel Axis for the Reconstruction of Stage-Four Primary Ischial Pressure Sores-A New Design

Background  “Subfascial void reconstruction” in ischial pressure sores (IPSs) goes a long way in the amelioration of the common complications like persistent drainage, infection, wound dehiscence, and late recurrence. No locoregional flaps suffice this requirement. So we have designed a chimeric pedicled flap based on the inferior gluteal vessel axis (IGVA) perforators with two tissue components: (1) Pacman-style fasciocutaneous flap on a perforator and (2) gluteus maximus muscle (inferior portion) on another independent perforator.

Aim and Methods  After confirming the feasibility of novel design of chimeric pedicled IGVA perforator flap with cadaver study, we embarked on the clinical study with this chimeric flap. In this prospective cohort study, the study and the control existed in the same patient so that the biological factors affecting the wound healing would be the same.

Results  Twenty-one patients were included whose mean age was 39 years. Late recurrence occurred in one patient (4.8%) of chimeric flap while the control group (who had undergone conventional reconstruction) had recurrence in 11 patients (52.4%). On assessment with overall institutional score, grade A was observed in 18 patients of the chimeric IGVA flap group ( p < 0.045), and in only 3 patients of the control group.

Conclusions  This anatomically construed flap, a new addendum in the armamentarium of reconstruction of IPSs, with its potential to congruently fill the ischiogluteal subfascial void may provide a lasting solution for preventing recurrences.

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

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

Pressure Ulcer Risk Factors in Persons with Mobility-Related Disabilities

OBJECTIVE

To assess pressure ulcer (PU) risk in persons with mobility impairments using a large data set to identify demographic, laboratory, hemodynamic, and pharmacologic risk factors.

METHODS

The cohort of interest was persons with disabilities who have mobility impairments and are diagnostically at risk of PUs. To define this cohort, diagnoses that qualify patients for skin protection wheelchair cushions were used. Data were obtained from the Cerner Health Facts data warehouse. Two cohorts were defined: persons with and without a history of PUs. Analysis included descriptive statistics and multivariate logistic regression modeling. Variables retained in the model were identified using LASSO, gradient boosting, and Bayesian model averaging.

MAIN RESULTS

The resulting cohorts included more than 87,000 persons with a history of PUs and more than 1.1 million persons who did not have a PU. The data revealed seven disability groups with the greatest prevalence of PUs: those with Alzheimer disease, cerebral palsy, hemiplegia, multiple sclerosis, paraplegia/quadriplegia, Parkinson disease, and spina bifida. Ulcers in the pelvic region accounted for 82% of PUs. Persons with disabilities who were male or black had a greater prevalence of PUs. Physiologic risk factors included the presence of kidney or renal disease, decreased serum albumin, and increased serum C-reactive protein.

CONCLUSIONS

The results indicate that, although persons with disabilities can exhibit a wide functional range, they remain at risk of PUs and should be evaluated for proper preventive measures, including support surfaces and wheelchair cushions.

"Unknown world of wheelchairs" A mixed methods study exploring experiences of wheelchair and seating assistive technology provision for people with spinal cord injury in an Irish context

AIM

This study explores people living with spinal cord injury (SCI) experiences and perspectives of wheelchair and seating assistive technology service provision within an Irish context. There are few studies that examine the process of wheelchair and seating provision and the connection between satisfaction, performance, and participation.

METHOD

This mixed methods study explores participant experiences in two parts. Part one presents a thematic analysis of eight in-depth semi-structured interviews with wheelchair service users living with SCI. Part two presents the results content and frequency analysis of an on-line survey of wheelchair service user's experience and satisfaction with wheelchair and seating service provision from respondents with SCI (n = 117) taken from a larger national survey from respondents with various diagnoses (n = 273).

RESULTS

Findings from the interviews and survey revealed the meaning of wheelchair and seating assistive technology provision as essential to life following SCI. Barriers within the provision system such as wait times and funding were found to impede people's rights and freedom from initial assessment through to follow up, maintenance and repair.

CONCLUSIONS

The current implementation of wheelchair and seating assistive technology provision as described in this paper impacts the ability of individuals living with an SCI to participate as equal members of society. A review of wheelchair provision is essential to optimize access to services for appropriate wheelchairs.IMPLICATIONS FOR REHABILITATIONAs a basic human right, appropriate wheelchair and seating assistive technology provision facilitates people's optimal independence, health and well-being, social engagement, and participation in everyday life.The development of adequate wheelchair services should be a priority area for individuals with SCI who use wheelchair and seating assistive technology.National wheelchair and seating assistive technology provision policies in alignment with internationally developed best practice guidelines to provide equal access to services which include assessment, delivery, training, maintenance, and follow-up are essential.

The Swedish SPinal Cord Injury Study on Cardiopulmonary and Autonomic Impairment: Methodology, Cohort Demographics, and Initial Results

OBJECTIVE

The aim of the study was to present the methodology, cohort demographics, and initial results of the Swedish SPinal Cord Injury Study on Cardiopulmonary and Autonomic Impairment (SPICA).

DESIGN

The SPICA is based on the Swedish CArdioPulmonary BioImage Study, a study on cardiopulmonary diseases in a cohort of 30,000 people. The assessments in the SPICA cover the structure and function of the cardiopulmonary and autonomic systems using bioimaging and functional analyses, together with a study-specific questionnaire and generic and spinal cord injury-specific assessment tools. The inclusion criteria were as follows: age 50-65 yrs, traumatic spinal cord injury of 5 yrs or more, and injury levels C1-T6, American Spinal Injury Association Impairment Scale A-C.

RESULTS

Of 38 potential participants, 25 comprised the final sample (20% women, mean age 58 yrs, mean time since injury 28 yrs). Eight percent had sustained a cardiovascular event, and 72% were classified as a high risk for cardiovascular disease. Asthma was previously diagnosed in only 8%, and none had chronic obstructive pulmonary disease.

CONCLUSIONS

The risk for cardiovascular disease in people with severe high-level spinal cord injury is a major clinical concern. Forthcoming studies in the SPICA will provide new knowledge of cardiopulmonary health in this cohort, which can guide future research and be used to develop long-term management.

A qualitative analysis of pressure injury development among medically underserved adults with spinal cord injury

Purpose: Medically underserved adults with spinal cord injury (SCI) remain at high risk of incurring medically serious pressure injuries even after receiving education in prevention techniques. The purpose of this research is to identify circumstances leading to medically serious pressure injury development in medically underserved adults with SCI during a lifestyle-based pressure injury prevention program, and provide recommendations for future rehabilitation approaches and intervention design.Methods: This study entailed a qualitative secondary case analysis of treatment notes from a randomized controlled trial. Participants were 25 community-dwelling, medically underserved adults with SCI who developed medically serious pressure injuries during the course of the intervention of the RCT.Results and conclusions: Among the 25 participants, 40 unique medically serious pressure injuries were detected. The six themes related to medically serious pressure injury development were: (1) lack of rudimentary knowledge pertaining to wound care; (2) equipment and supply issues; (3) comorbidities; (4) non-adherence to prescribed bed rest; (5) inactivity; and (6) circumstances beyond the intervention's reach. Together, these factors may have undermined the effectiveness of the intervention program. Modifications, such as assessing health literacy levels of patients prior to providing care, providing tailored wound care education, and focusing on equipment needs, have potential for altering future rehabilitation programs and improving health outcomes.Implications for rehabilitationTo provide patients with spinal cord injury with the necessary information to prevent medically serious pressure injury development, health care providers need to understand their patient's unique personal contexts, including socio-economic status, language skills, and mental/cognitive functioning.When providing wound care information to patients with spinal cord injury who have developed a medically serious pressure injury, practitioners should take into account the level of health literacy of their patient in order to provide education that is appropriate and understandable.Practitioners should be aware of how to help their patient advocate for outside services and care that address their equipment needs, such as finding funding or grants to pay for expensive medical equipment.

The use of a mobile educational tool on pressure injury education for individuals living with spinal cord injury/disease: a qualitative research study

Background: As many as 30-60% of individuals living with spinal cord injury/disease (SCI/D) experience at least one pressure injury (PI) in their lifetime. Best practice guidelines in SCI/D rehabilitation emphasize the importance of providing education regarding PI prevention and management for individuals living with SCI/D. Mobile educational applications can be used for PI education however there is limited research on the user-experiences of mobile educational applications about PIs for individuals living with SCI/D.Objectives: The purpose of this study was to explore the experiences of individuals living with SCI/D on the use of Pressure Ulcer Target (PUT), a mobile educational app for PI prevention and management.Methods/Overview: Nine participants living with SCI/D used PUT over two weeks. Individual semi-structured interviews were conducted to explore the participants' perceptions regarding the utility, aesthetics and ease of use of PUT and suggested modifications. A conventional content analysis was used to identify themes and categories from the data.Results: User-experiences with PUT fell into four themes: (1) Strengths and weakness; (2) Target population; (3) Key concepts and messages; and (4) Recommendations for improvement.Conclusions: PUT serves as a review of previously acquired PI knowledge and should be introduced early in rehabilitation to motivate users to prevent PIs. Future studies exploring healthcare professionals' perspectives of PUT are warranted.Implications for rehabilitationPUT aids individuals living with SCI/D in the community to review PI prevention and management strategies that they learned as inpatients.The use of pictures to deliver patient education regarding PI prevention and management through a mHealth app is recommended.PUT should be introduced early in rehabilitation to motivate users to prevent PIs.

The global burden of pressure ulcers among patients with spinal cord injury: a systematic review and meta-analysis

BACKGROUND

Pressure ulcers (PU), one of the common challenging public health problems affecting patient with spinal cord injury. PUs occurs over bony areas of the body where pressure and tissue distortion is greatest. It has a significant impact to the patient and health care system. Moreover, it has psychological, physical, social burden and decrease the quality of life (QoL) of patients. Despite its serious complications, limited evidence is available on the global magnitude of pressure ulcers among patient with spinal cord injury. Hence, this review and meta-analysis aimed to estimate the global magnitude of pressure ulcers among patient with spinal cord injury.

METHODS

PubMed, Scopus, Google Scholar, African Journals Online, PsycINFO, and Web of Science were systematically searched to retrieve related articles. The Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guideline was followed. DerSimonian and Laird random-effects model was applied to obtain the pooled effect size. To investigate heterogeneity across the included studies, I2 test was employed. Publication bias was examined using funnel plot and Egger's regression test statistic. Sensitivity analysis was deployed to see the effect of a single study on the overall estimation. Analysis was done using STATA™ Version 14 software.

RESULTS

A total of 24 studies which comprises of 600,078 participants were included in this study. The global pooled magnitude of pressure ulcers among patients with spinal cord injury was 32.36% (95% CI (28.21, 36.51%)). Based on the subgroup analysis, the highest magnitude of pressure ulcer was observed in Africa 41.19% (95% CI: 31.70, 52.18).

CONCLUSION

This systematic review and meta-analysis revealed that about one in three patients with spinal cord injury had pressure ulcers. This implies that the overall global magnitude of pressure ulcer is relatively high. Therefore, policy maker and other concerned body should be design country context- specific preventive strategies to reduce the burden of pressure ulcers in patients with spinal cord injury.

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

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

Quality of life of persons with traumatic spinal cord injury in rural Kilimanjaro, Tanzania: a community survey

AIM

To describe the quality of life of persons with traumatic spinal cord injury (TSCI) in a rural area of a low-income country.

METHODS

This was a cross-sectional descriptive study in which snowballing was used to identify persons with TSCI in their homes. A Kiswahili version of the short version of the World Health Organization quality of life questionnaire was used for data collection. Data were analyzed descriptively and independent samples t-tests were used to calculate the difference in the mean scores between groups.

RESULTS

Eighty persons with TSCI with a mean age of 42.29 ± 11.4 years were identified, 68.8% of whom were males. The highest scoring domains were psychological (12.76 ± 2.55) and social relationships (12.62 ± 2.95). The lowest scores were for physical (11.48 ± 2.74) and environment (9.59 ± 2.68) domains. Significantly higher scores were associated with younger age in: physical (0.05), social relationships (0.01), and environment (0.02) domains (p value < 0.05).

CONCLUSIONS

Persons with TSCI in the Kilimanjaro rural area registered a relatively low quality of life in which the most affected domains are physical health and environment.Implications for rehabilitationQuality of life is the ultimate goal in the rehabilitation of persons with any irreversible disability such as spinal cord injury.It is important for rehabilitation professionals to know which domains of quality of life are most affected among persons with spinal cord injury.Rehabilitation professionals ought to understand and address physical health and environmental issues that affect persons with traumatic spinal cord injury in rural resource-constrained areas.Addressing physical health and environmental challenges for persons with spinal cord injury in resource-constrained rural areas require involvement of the family, rehabilitation personnel, policy makers, and the community.

Exploring the Influence of Wheelchair-User Interface and Personal Characteristics on Ischial Tuberosity Peak Pressure Index and Gradient in Elite Wheelchair Basketball Players

This pilot study investigated the relationship between personal and wheelchair factors on skin pressures at the ischial tuberosity in wheelchair basketball players. Seventeen wheelchair basketball players (7 male and 10 female) were evaluated during static and dynamic propulsive conditions while peak pressure index and peak pressure gradient were recorded with an interface pressure mat. The results showed that greater seat dump angles and backrest heights were negatively associated with the peak pressure index. Therapeutic cushion use was moderately associated with a reduced peak pressure gradient. Higher-class players used chair configurations associated with augmented pressure; however, classification status alone was not associated with pressure magnitude. Body mass index was negatively correlated with the static peak pressure gradient at levels approaching significance (p < .10). In conclusion, greater seat dump angles and backrest heights may provide pressure relief, whereas greater body mass index and therapeutic cushion use may reduce pressure gradients.

Integument: Guidelines for the care of people with spina bifida

PURPOSE

Skin-related issues have a significant impact on health, activities of daily living, and quality of life among people with spina bifida. Data presented by select clinics that participate in the National Spina Bifida Patient Registry reported that 26% of individuals had a history of pressure injuries with 19% having had one in the past year. The spina bifida community lack direct guidelines on prevention of these and other skin related issues. The Integument (skin) Guidelines focus on prevention, not treatment, of existing problems.

METHODS

Using a consensus building methodology, the guidelines were written by experts in spina bifida and wound care.

RESULTS

The guidelines include age-grouped, evidence-based guidelines written in the context of an understanding of the whole person. They are presented in table format according to the age of the person with spina bifida.

CONCLUSION

These guidelines present a standardized approach to prevention of skin-related issues in spina bifida. Discovering what results in successful minimization of skin-related issues with testing of technology or prevention strategies is the next step in protecting this vulnerable population.

Traumatic vs non-traumatic spinal cord injury: A comparison of primary rehabilitation outcomes and complications during hospitalization

Objective: To compare outcome for patients with traumatic (TSCI) and non-traumatic spinal cord injuries (NTSCI) after primary rehabilitation regarding neurological improvement measured by the American Spinal Injury Association Impairment Scale (AIS), length of stay and complications.Design: Retrospective comparative cohort study on patients with TSCI and NTSCI, hospitalized during a ten-year period at Haukeland University Hospital, Norway. Impairment, length of stay and complications during first in-patient rehabilitation period were analyzed. Uni- and multivariate analysis was performed.Setting: Spinal Cord Rehabilitation Unit, Haukeland University Hospital, NorwayParticipants: A total of 174 persons with a spinal cord injury (SCI) were included; 102 with TSCI and 72 with NTSCI.Outcome measures: Neurological improvement measured by AIS from admission to discharge, number of weeks in the hospital, frequency and significance of complications were compared.Results: Improvement in AIS after primary rehabilitation did not differ between TSCI and NTSCI. Length of stay was in average 3.4 weeks longer for TSCI. Urinary tract infections and pressure ulcers significantly influenced length of stay in both groups. Urinary tract infections were more frequent in TSCI (67%) vs NTSCI (42%). Pressure ulcers were more frequent among NTSCI (24%) vs TSCI (14%). Pneumonia and neuropathic pain did not depend on etiology and did not influence length of stay.Conclusions: Patients with SCI have a rehabilitation potential regardless of etiology. Complications are frequent in both groups and often prolong hospitalization. Complication patterns differ in the two groups, and specific prevention and optimal treatment will shorten and optimize the length of primary rehabilitation.

Development of Tissue Integrity indicators to advance the quality of spinal cord injury rehabilitation: SCI-High Project

Objective: To establish structure, process and outcome indicators to evaluate tissue integrity in Canadians with spinal cord injury or disease (SCI/D) in the first 18 months following inpatient rehabilitation admission. Method: A Working Group comprised of Canadian subject matter experts in the Domain of Tissue Integrity was formed to define the construct of tissue integrity. A literature review was conducted and a Driver diagram produced to identify factors that influence tissue integrity in individuals with SCI/D. Facilitated meetings were conducted to identify and achieve consensus on structure, process and outcome indicators. Rapid cycle testing was used to pilot test proposed indicators for face validity and feasibility within a quality improvement context. Results: The structure indicators are the proportion of patients with SCI/D who have access to a mirror for skin checks and the proportion of patients who have access to patient education on tissue integrity; the process indicator is the proportion of patients who completed daily head-to-toe skin checks; the intermediary outcome indicator is pressure injury (PI) incidence during inpatient rehabilitation; and the final outcome indicator is the proportion of individuals with intact skin at 18 months following rehabilitation admission. Conclusion: The set of indicators established for the Domain of Tissue Integrity are specifically focused on aspects of care that can impact the maintenance of tissue integrity and the prevention of PI and align with current practice guidelines. The implementation and evaluation of these indicators nationally have the potential to improve care for Canadians with SCI/D.

Influence of wheelchair user interface and personal characteristics on static and dynamic pretibial skin pressures in elite wheelchair racers, a pilot study

Context/objective: To examine personal (athletic classification, age, sex, body mass index, duration of disability, tactile sensation of lower extremities) and wheelchair (kneeling plate angle) factors associated with increased pretibial skin pressures in elite wheelchair racers.

Design: Cross-sectional study.

Setting: University-based laboratory in Champaign, USA.

Participants: A convenience sample of elite wheelchair races with traumatic spinal cord injury and spinal disease were recruited for participation.

Interventions: Interface pressure mapping was used to examine athletes' average and peak pretibial skin pressures in their own racing wheelchairs during static and dynamic (propulsive) conditions on a dynamometer.

Outcome measures: The study examined associations between personal and wheelchair factors and pressure, differences in pressure between static and dynamic conditions, and the influence of athletic classification (T53 vs. T54) on kneeling plate angle preference and skin pressure magnitudes.

Results: Increased kneeling plate angle was moderately associated with dynamic pressures. T53 athletes utilized more vertical kneeling angles and experienced larger average and peak pressures during propulsion. Duration of disability was negatively associated with all measures of pressure. Overall, mean dynamic peak pressure was significantly greater than mean static peak pressure.

Conclusion: This pilot study represents a first step in understanding the influence of user interface on potentially injurious skin pressures in wheelchair racers. Vertical kneeling plate configurations were associated with increased pressures while increased years with disability was associated with lower pretibial pressures. In addition, T53 athletes with less trunk function may be at a greater risk for experiencing larger interface pressures than T54 athletes.

Severe pressure ulcers requiring surgery impair the functional outcome after acute spinal cord injury

STUDY DESIGN

Retrospective matched cohort study.

OBJECTIVES

Assessing the influence of surgically managed grade 3 and 4 pressure ulcers (PU) in the acute phase after spinal cord injury (SCI) on the neurological and functional outcome after 1 year.

SETTING

Specialized SCI-unit within a level 1 trauma center in Murnau, Germany.

METHODS

We performed a retrospective matched cohort study. For every patient with acute SCI and a PU requiring surgery, we identified matched controls within our database in a 1:3 ratio. Matching criteria were: AIS-grade (American Spinal Injury Association Impairment Scale), neurological level and age. The scores of the SCIM-III (Spinal Cord Independence Measure) and the ISNCSCI (International Standards for Neurological Classification of Spinal Cord Injury) as well as the total length of stay (LOS) at the hospital were used as outcome parameters. We applied a stratified analysis using a conditional logistic regression to test for group differences in each outcome parameter of the study.

RESULTS

In a 6-year period (2010-2015) 28 patients required flap surgery due to 3-4° PU in the acute phase after SCI. Of these patients, 15 had complete data sets according to the EMSCI (European Multicenter Study about Spinal Cord Injury) protocol. Patients with severe PUs during the acute SCI phase had a significantly impaired functional outcome. After 1 year the improvement of the SCIM score was significantly lower in the PU group compared to the control group (17.4 versus 30.5; p < 0.006). However, the change in AIS grade after 1 year was not significantly affected. The LOS was prolonged by a mean of 48 days in the PU group (p < 0.006).

CONCLUSIONS

Severe PUs requiring surgery in the acute phase after SCI impair the functional outcome and increase LOS. Preventive measures should be applied to all acute SCI patients. Patients should be transferred to specialized SCI-centers as soon as possible.

Exploring the relationship between self-reported urinary tract infections to quality of life and associated conditions: insights from the spinal cord injury Community Survey

STUDY DESIGN

Descriptive study OBJECTIVES: Urinary tract infections (UTIs) are one of the most frequent types of infections following spinal cord injury (SCI). Here we assess the relationship between frequency of UTIs and activity level/overall quality of life (QOL) measures, determine the frequency of temporally associated conditions associated with UTI and identify factors associated with frequent UTIs.

SETTING

Canada METHODS: The Spinal Cord Injury Community Survey was developed to assess major dimensions of community living and health outcomes in persons with chronic SCI in Canada. Participants were stratified by self-reported UTI frequency. The relationship between UTI frequency and QOL, health resource utilization, and temporally associated conditions were assessed. Results were analysed with cross tabulations, χ² tests, and ordinal logistic regression.

RESULTS

Overall 73.5% of participants experienced at least one self-reported UTI since the time of injury (mean 18.5 years). Overall QOL was worse with increasing frequency of these events. Those with frequent self-reported UTIs had twice as many hospitalizations and doctors' visits and were limited in financial, vocational and leisure situations, physical health and ability to manage self-care as compared with those with no UTIs. Self-reported UTIs were associated with higher incidence of temporally associated conditions including bowel incontinence, constipation, spasticity, and autonomic dysreflexia. Individuals who were younger and female were more likely to have frequent UTIs and those with constipation and autonomic dysreflexia had worse QOL.

CONCLUSIONS

Higher frequency self-reported UTIs is related to poor QOL of individuals with long-term SCI. These findings will be incorporated into SCI UTI surveillance and management guidelines.

Pattern detection from seating pressure distribution during wheelchair motion using deep embedded clustering

To minimize the occurrence of ulcers in high-risk mobile individuals such as wheelchair users, it is necessary to detect all typical distribution patterns and to indentify the patterns that may be associated with pressure ulcers. However, pattern detection is difficult because the pressure distribution during motion includes a variety of patterns compared to those of static postures. Thus, the establishment of a method to detect typical patterns based on distribution patterns is important. We utilized deep embedded clustering for identification purposes. This clustering technique extracts features using auto-encoder and simultaneously optimizes data points into the clusters, which might realize good clustering performance due to the detected optimal features. We used a pressure distribution dataset that was pre-labeled by nursing experts. The dataset consisted of a total of 26944 distribution images with ten class annotations. The clustering method including traditional approaches (k-means and principal component analysis plus k-means) were compared with deep embedded clustering while the threshold to noise reduction was changing. The deep embedded clustering with 80 mmHg threshold achieved the best performance. This approach also tended to be less dependent on the threshold values.

Determining Pressure Injury Risk on Admission to Inpatient Spinal Cord Injury Rehabilitation: A Comparison of the FIM, Spinal Cord Injury Pressure Ulcer Scale, and Braden Scale

OBJECTIVE

Assess the utility of the admission Spinal Cord Injury Pressure Ulcer Scale (SCIPUS), Braden Scale, and the FIM for identifying individuals at risk for developing pressure injury during inpatient spinal cord injury (SCI) rehabilitation.

DESIGN

Retrospective cohort.

SETTING

Two tertiary rehabilitation centers.

PARTICIPANTS

Individuals (N=754) participating in inpatient SCI rehabilitation.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Logistic regression analysis was performed to determine the utility of the SCIPUS, Braden Scale, and FIM for identifying individuals at risk for developing pressure injury (PI) during inpatient SCI rehabilitation. Sensitivity, specificity, positive predictive value, negative predictive value, false negative rate, odds ratio, likelihood ratio, and area under the curve (AUC) are reported.

RESULTS

The SCIPUS total score and its individual items did not demonstrate acceptable accuracy (AUC≥0.7) whereas the Braden Scale (0.73) and the FIM score (0.74) did. Once items were dichotomized into high and low risk categories, 1 Braden item (friction and shear), 5 FIM items (bathing, toileting, bed/chair transfer, tub/shower transfer, toilet transfer), the FIM transfers subscale, FIM Motor subscale, and the FIM instrument as a whole, maintained AUCs ≥0.7 and negative predictive values ≥0.95. The FIM bed/chair transfer score demonstrated the highest likelihood ratio (2.62) and overall was the most promising measure for determining PI risk.

CONCLUSION

Study findings suggest that a simple measure of mobility, admission FIM bed/chair transfer score of 1 (total assist), can identify at-risk individuals with greater accuracy than both an SCI specific instrument (SCIPUS) and a PI specific instrument (Braden). The FIM bed/chair transfer score can be readily determined at rehabilitation admission with minimal administrative and clinical burden.

An inclusive, online Delphi process for setting targets for best practice implementation for spinal cord injury

RATIONALE, AIMS, AND OBJECTIVES

The Spinal Cord Injury Knowledge Mobilization Network is a pan-Canadian community of practice composed of seven rehabilitation hospitals. The goal of this network is to utilize implementation science processes to facilitate the adoption of best practice in spinal cord injury (SCI) rehabilitation. In addition to selecting specific practices for implementation, a key aspect of effective implementation is the engagement of stakeholders in decision-making processes. To achieve this, the network utilized a Delphi process to reach consensus on two pressure ulcer prevention and management practices to be implemented in SCI inpatient rehabilitation. A diverse, multidisciplinary panel of clinicians, researchers, sponsoring agency representatives, and persons with SCI participated in this process.

METHOD

An online Delphi process was conducted in order to prioritize pressure ulcer prevention and management best practice recommendations and performance indicators for implementation. The process was conducted in six stages: (1) steering committee selection; (2) identification and selection of evidence; (3) participant selection and recruitment; (4) survey development; (5) identification of voting criteria; and (6) five rounds of voting.

RESULTS

The Delphi process resulted in the selection of two best practices: (1) comprehensive risk assessment and (2) education for pressure ulcer prevention and management in persons with SCI.

CONCLUSIONS

In this Delphi process, a large expert panel achieved consensus on best practice recommendations and associated performance indicators for implementation. This process was undertaken as a first step towards optimization of service delivery and outcomes for persons with SCI across Canada.

Facilitators and Barriers for Implementing an Internet Clinic for the Treatment of Pressure Injuries

Background: Pressure injuries (PIs) represent a frequent, often preventable, secondary complication of spinal cord injury (SCI) with serious consequences to health, societal participation, and quality of life. Specialized knowledge and service delivery related to treatment and prevention are typically located within major health centers. Introduction: For persons with SCI living at home, it can be challenging to access specialized PI care. A telehealth approach could help mitigate this challenge. This multisite pilot investigation assessed the feasibility of integrating information technologies within the management of PIs. Materials and Methods: Each study site formed a specialized interdisciplinary care team that identified components of their standard clinical care pathway and examined how they could be integrated with study technologies. A monitoring system was utilized to enable patients and caregivers to exchange clinical information with the care team. Results: Clinician and patient focus groups were completed to identify facilitators and barriers for long-term implementation. Findings demonstrate that this method of service delivery is feasible but requires further development. Discussion: This model of care requires refinement to address technological, regulatory, and clinician acceptance barriers; however, increased access to these services has the potential for improving PI healing or prevention rates in comparison with those not able to access specialized services. Conclusions: This project demonstrates that PI treatment services can be delivered effectively through the internet. Future trials can investigate efficacy and cost-effectiveness of this model of care to inform sustained implementation.

Biomarkers in Spinal Cord Injury: Prognostic Insights and Future Potentials

Spinal Cord Injury (SCI) is a major challenge in Neurotrauma research. Complex pathophysiological processes take place immediately after the injury and later on as the chronic injury develops. Moreover, SCI is usually accompanied by traumatic injuries because the most common modality of injury is road traffic accidents and falls. Patients develop significant permanent neurological deficits that depend on the extent and the location of the injury itself and in time they develop further neurological and body changes that may risk their mere survival. In our review, we explored the recent updates with regards to SCI biomarkers. We observed two methods that may lead to the appearance of biomarkers for SCI. First, during the first few weeks following the injury the Blood Spinal Cord Barrier (BSCB) disruption that releases several neurologic structure components from the injured tissue. These components find their way to Cerebrospinal Fluid (CSF) and the systemic circulation. Also, as the injury develops several components of the pathological process are expressed or released such as in neuroinflammation, apoptosis, reactive oxygen species, and excitotoxicity sequences. Therefore, there is a growing interest in examining any correlations between these components and the degrees or the outcomes of the injury. Additionally, some of the candidate biomarkers are theorized to track the progressive changes of SCI which offers an insight on the patients' prognoses, potential-treatments-outcomes assessment, and monitoring the progression of the complications of chronic SCI such as Pressure Ulcers and urinary dysfunction. An extensive literature review was performed covering literature, published in English, until February 2018 using the Medline/PubMed database. Experimental and human studies were included and titles, PMID, publication year, authors, biomarkers studies, the method of validation, relationship to SCI pathophysiology, and concluded correlation were reported. Potential SCI biomarkers need further validation using clinical studies. The selection of the appropriate biomarker group should be made based on the stage of the injuries, the accompanying trauma and with regards to any surgical, or medical interference that might have been done. Additionally, we suggest testing multiple biomarkers related to the several pathological changes coinciding to offer a more precise prediction of the outcome.

Hospital based care at home; study protocol for a mixed epidemiological and randomized controlled trial

Background

Individuals with spinal cord injuries (SCI) are prone to pressure ulcers (PUs) because of the loss of sensorimotor function involved as well as increased skin moisture. Treatment of PU after SCI is complicated, involving different specialties and with need for long-lasting follow-up. This study should identify risk factors for PU after SCI, and find an effective and less time-consuming treatment for the condition among different available methods for follow-up.

Method/design

The first part of this research project aims to investigate the prevalence of PU among persons with SCI based on an epidemiological design. The study will identify possible risk factors for acquiring PU. A questionnaire focusing on previous and present PUs will be sent to persons who suffered SCIs between January 2004 and January 2014. In the second part we will compare two different treatment regimens of PU through a randomized controlled pilot trial (RCT) where we will compare outpatient SCI follow-up in a hospital versus outpatient follow-up from the patient’s home, using telemedicine (teleSCI) interventions. We will compare the healing of the PU in the two groups (usual care versus teleSCI). The Tissue, Infection, Moisture Edge (TIME) registration form, the Photographic Wound Assessment Tool (PWAT) and the change in the ulcer size will be used to monitor the healing. Changes in health-related quality of life (HRQoL) and the need for assistance will be assessed using the Five Dimensions European Quality of Life scale (EQ-5D), the generic Medical Outcomes Study 12-item Short Form Health Survey (SF-12) modified version, the International Spinal Cord Injury Quality of Life Data set (ISCI-QoL Data set), and the Spinal Cord Independence Measure scale, version III (SCIM III). In addition to primary outcome measures, a cost-benefit evaluation and an assessment of patient satisfaction and participation will be performed, using customized questionnaires.

Discussion

The first part of the research project will reveal the epidemiology of PU after SCI, and explore the risk factors. This part enables further prevention of PU after SCI and this information will be used in the follow-up RCT. Videoconferencing in the outpatient follow-up of persons with SCI and PU will change clinical routines and facilitate interdisciplinary collaboration, communication and competence exchange among participants of the health care services. Our research protocol allows comparing methods for interaction between medical specialists at hospitals, local caregivers in the community, next of kin, and persons with SCI and PU. The RCT should identify advantages as well as challenges in the management of PU in different follow-up settings. This study aims to identify risk factors for PU after SCI, and find an effective and less time consuming treatment for the condition among different available methods for follow- up.

Surgical management of lower limb fractures in patients with spinal cord injury less associated with complications than non-operative management: A retrospective series of cases

OBJECTIVES

To evaluate the difference in terms of overall complications between surgical and non-surgical management of lower limb fractures in patients with chronic spinal cord injury (SCI).

DESIGN

A 13-year retrospective study including patients with chronic spinal cord lesion admitted for sublesional lower limb fractures.

SETTING

University hospital SCI reference departments (Rehabilitation department and orthopedic department).

PARTICIPANTS

Forty patients with SCI were included, 24 men and 16 women. Fifty-six distinct fracture occurrences were responsible for a total of 59 lower limb fractures. We compared the number of overall complications between surgical and non-surgical management of fractures.

RESULTS

Non-surgical management was realized for 19 fractures and surgery for 40. Characteristics of operated and non-operated patients at the time of each fracture occurrence did not differ concerning age (P = 0.430), sex (P = 0.890), lesion levels (P = 0.410) and AIS classification (P = 0.790). Data analysis highlighted 20 complications directly due to the fracture site for 16 distinct fractures. Seven medical complications were found in 5 distinct fracture events. Only 10 (25.0%) of 40 surgical managements had at least one medical or post-surgical complication, whereas 12 (63.2%) of 19 non-operative managements had at least one complication. Therefore, the overall rate of complications was significantly higher after non-surgical treatment (P = 0.044).

CONCLUSION

Lower extremity fractures due to osteoporosis in patients with SCI are responsible for local and general complications. When possible, surgery may be the best management to propose because of fewer overall complications.

Organisation of health services for preventing and treating pressure ulcers

BACKGROUND

Pressure ulcers, which are a localised injury to the skin, or underlying tissue, or both, occur when people are unable to reposition themselves to relieve pressure on bony prominences. Pressure ulcers are often difficult to heal, painful, expensive to manage and have a negative impact on quality of life. While individual patient safety and quality care stem largely from direct healthcare practitioner-patient interactions, each practitioner-patient wound-care contact may be constrained or enhanced by healthcare organisation of services. Research is needed to demonstrate clearly the effect of different provider-orientated approaches to pressure ulcer prevention and treatment.

OBJECTIVES

To assess the effects of different provider-orientated interventions targeted at the organisation of health services, on the prevention and treatment of pressure ulcers.

SEARCH METHODS

In April 2018 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched three clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting.

SELECTION CRITERIA

Randomised controlled trials (RCTs), cluster-RCTs, non-RCTs, controlled before-and-after studies and interrupted time series, which enrolled people at risk of, or people with existing pressure ulcers, were eligible for inclusion in the review.

DATA COLLECTION AND ANALYSIS

Two review authors independently performed study selection, risk of bias assessment, data extraction and GRADE assessment of the certainty of evidence.

MAIN RESULTS

The search yielded a total of 3172 citations and, following screening and application of the inclusion and exclusion criteria, we deemed four studies eligible for inclusion. These studies reported the primary outcome of pressure ulcer incidence or pressure ulcer healing, or both.One controlled before-and-after study explored the impact of transmural care (a care model that provided activities to support patients and their family/partners and activities to promote continuity of care), among 62 participants with spinal cord injury. It is unclear whether transmural care leads to a difference in pressure ulcer incidence compared with usual care (risk ratio (RR) 0.93, 95% confidence interval (CI) 0.53 to 1.64; very low-certainty evidence, downgraded twice for very serious study limitations and twice for very serious imprecision).One RCT explored the impact of hospital-in-the-home care, among 100 older adults. It is unclear whether hospital-in-the-home care leads to a difference in pressure ulcer incidence risk compared with hospital admission (RR 0.32, 95% CI 0.03 to 2.98; very low-certainty evidence, downgraded twice for very serious study limitations and twice for very serious imprecision).A third study (cluster-randomised stepped-wedge trial), explored the impact of being cared for by enhanced multidisciplinary teams (EMDT), among 161 long-term-care residents. The analyses of the primary outcome used measurements of 201 pressure ulcers from 119 residents. It is unclear if EMDT reduces the pressure ulcer incidence rate compared with usual care (hazard ratio (HR) 1.12, 95% CI 0.74 to 1.68; very low-certainty evidence, downgraded twice for very serious study limitations and twice for very serious imprecision). It is unclear whether there is a difference in the number of wounds healed (RR 1.69, 95% CI 1.00 to 2.87; very low-certainty evidence, downgraded twice for very serious study limitations and twice for very serious imprecision). It is unclear whether there is a difference in the reduction in surface area, with and without EMDT, (healing rate 1.006; 95% CI 0.99 to 1.03; very low-certainty evidence, downgraded twice for very serious study limitations and twice for very serious imprecision). It is unclear if EMDT leads to a difference in time to complete healing (HR 1.48, 95% CI 0.79 to 2.78, very low-certainty evidence, downgraded twice for very serious study limitations and twice for very serious imprecision).The final study (quasi-experimental cluster trial), explored the impact of multidisciplinary wound care among 176 nursing home residents. It is unclear whether there is a difference in the number of pressure ulcers healed between multidisciplinary care, or usual care (RR 1.18, 95% CI 0.98 to 1.42; very low-certainty evidence, downgraded twice for very serious study limitations and twice for very serious imprecision). It is unclear if this type of care leads to a difference in time to complete healing compared with usual care (HR 1.73, 95% CI 1.20 to 2.50; very low-certainty evidence; downgraded twice for very serious study limitations and twice for very serious imprecision).In all studies the certainty of the evidence is very low due to high risk of bias and imprecision. We downgraded the evidence due to study limitations, which included selection and attrition bias, and sample size. Secondary outcomes, such as adverse events were not reported in all studies. Where they were reported it was unclear if there was a difference as the certainty of evidence was very low.

AUTHORS' CONCLUSIONS

Evidence for the impact of organisation of health services for preventing and treating pressure ulcers remains unclear. Overall, GRADE assessments of the evidence resulted in judgements of very low-certainty evidence. The studies were at high risk of bias, and outcome measures were imprecise due to wide confidence intervals and small sample sizes, meaning that additional research is required to confirm these results. The secondary outcomes reported varied across the studies and some were not reported. We judged the evidence from those that were reported (including adverse events), to be of very low certainty.
