ABSTRACT
OBJECTIVE: We examined the impact of consenting to the Rick Hansen Spinal Cord Injury Registry (RHSCIR) on outcomes: acute length of stay (LOS), in-hospital mortality, medical complications (pressure injuries and pneumonia), and the final discharge destination following a spinal cord injury (SCI) using the national RHSCIR dataset. DESIGN: A retrospective cohort study was conducted using RHSCIR participant data from 2014 to 2019. Participants approached for enrollment were grouped into 1) PC: provided full consent including community follow-up (CFU) interviews, 2) DWC: declined CFU interviews but accepted minimal data collection that may include initial/final interviews and/or those who later withdrew consent, and 3) DC: declined consent to any participation. As no data was collected for the DC group, descriptive, bivariate, and multivariable regression analysis was limited to the PC and DWC groups. RESULTS: Of 2811 participants, 2101 (74.7%) were PC, 553 (19.7%) were DWC, and 157 (5.6%) were DC. DWC participants had significantly longer acute LOS, more acute pneumonias/pressure injuries, and were less likely to be discharged home than PC participants. All these associations - except pneumonia - remained significant in the multivariable analyses. CONCLUSION: Not participating fully in RHSCIR was associated with more complications and longer hospital stays.
ABSTRACT
Introduction: Several clinical prediction rules (CPRs) have been published, but few are easily accessible or convenient for clinicians to use in practice. We aimed to develop, implement, and describe the process of building a web-based CPR for predicting independent walking 1-year after a traumatic spinal cord injury (TSCI). Methods: Using the published and validated CPR, a front-end web application called "Ambulation" was built using HyperText Markup Language (HTML), Cascading Style Sheets (CSS), and JavaScript. A survey was created using QualtricsXM Software to gather insights on the application's usability and user experience. Website activity was monitored using Google Analytics. Ambulation was developed with a core team of seven clinicians and researchers. To refine the app's content, website design, and utility, 20 professionals from different disciplines, including persons with lived experience, were consulted. Results: After 11 revisions, Ambulation was uploaded onto a unique web domain and launched (www.ambulation.ca) as a pilot with 30 clinicians (surgeons, physiatrists, and physiotherapists). The website consists of five web pages: Home, Calculation, Team, Contact, and Privacy Policy. Responses from the user survey (n = 6) were positive and provided insight into the usability of the tool and its clinical utility (e.g., helpful in discharge planning and rehabilitation), and the overall face validity of the CPR. Since its public release on February 7, 2022, to February 28, 2023, Ambulation had 594 total users, 565 (95.1%) new users, 26 (4.4%) returning users, 363 (61.1%) engaged sessions (i.e., the number of sessions that lasted 10 seconds/longer, had one/more conversion events e.g., performing the calculation, or two/more page or screen views), and the majority of the users originating from the United States (39.9%) and Canada (38.2%). Discussion: Ambulation is a CPR for predicting independent walking 1-year after TSCI and it can assist frontline clinicians with clinical decision-making (e.g., time to surgery or rehabilitation plan), patient education and goal setting soon after injury. This tool is an example of adapting a validated CPR for independent walking into an easily accessible and usable web-based tool for use in clinical practice. This study may help inform how other CPRs can be adopted into clinical practice.
ABSTRACT
Introduction: Incidence and prevalence data are needed for the planning, funding, delivery and evaluation of injury prevention and health care programs. The objective of this study was to estimate the Canadian traumatic spinal cord injury (TSCI) incidence, prevalence and trends over time using national-level health administrative data. Methods: ICD-10 CA codes were used to identify the cases for the hospital admission and discharge incidence rates of TSCI in Canada from 2005 to 2016. Provincial estimates were calculated using the location of the admitting facility. Age and sex-specific incidence rates were set to the 2015/2016 rates for the 2017 to 2019 estimates. Annual incidence rates were used as input for the prevalence model that applied annual survivorship rates derived from life expectancy data. Results: For 2019, it was estimated that there were 1,199 cases (32.0 per million) of TSCI admitted to hospitals, with 123 (10% of admissions) in-hospital deaths and 1,076 people with TSCI (28.7 per million) were discharged in Canada. The estimated number of people living with TSCI was 30,239 (804/million); 15,533 (52%) with paraplegia and 14,706 (48%) with tetraplegia. Trends included an increase in the number of people injured each year from 874 to 1,199 incident cases (37%), an older average age at injury rising from 46.6 years to 54.3 years and a larger proportion over the age of 65 changing from 22 to 38%, during the 15-year time frame. Conclusion: This study provides a standard method for calculating the incidence and prevalence of TSCI in Canada using national-level health administrative data. The estimates are conservative based on the limitations of the data but represent a large Canadian sample over 15 years, which highlight national trends. An increasing number of TSCI cases among the elderly population due to falls reported in this study can inform health care planning, prevention strategies, and future research.
ABSTRACT
STUDY DESIGN: Cross-sectional survey in Canada. OBJECTIVES: To explore multimorbidity (the coexistence of two/more health conditions) in persons with non-traumatic spinal cord injury (NTSCI) and evaluate its impact on healthcare utilization (HCU) and health outcomes. SETTING: Community-dwelling persons. METHODS: Data from the Spinal Cord Injury Community Survey (SCICS) was used. A multimorbidity index (MMI) consisting of 30 secondary health conditions (SHCs), the 7-item HCU questionnaire, the Short Form-12 (SF-12), Life Satisfaction-11 first question, and single-item Quality of Life (QoL) measure were administered. Additionally, participants were grouped as "felt needed healthcare was received" (Group 1, n = 322) or "felt needed healthcare was not received" (Group 2, n = 89) using the HCU question. Associations among these variables were assessed using multivariable analysis. RESULTS: 408 of 412 (99%) participants with NTSCI reported multimorbidity. Constipation, spasticity, and fatigue were the most prevalent self-reported SHCs. Group 1 had a higher MMI score compared to Group 2 (p < 0.001). A higher MMI score correlated with the feeling of not receiving needed care (OR 1.4, 95% CI 1.08-1.21), lower SF-12 (physical/mental component summary scores), being unsatisfied with life, and lower QoL (all p < 0.001). Additionally, Group 1 had more females (p < 0.001), non-Caucasians (p = 0.034), and lower personal annual income (p = 0.025). CONCLUSIONS: Persons with NTSCI have multimorbidity, and the MMI score was associated with increased HCU and worse health outcomes. This work emphasizes the critical need for improved healthcare and monitoring. Future work determining specific thresholds for the MMI could be helpful for triage screening to identify persons at higher risk of poor outcomes.

STUDY DESIGN: Cohort study. OBJECTIVES: To evaluate the association between residential living location and health outcomes, environmental barriers, quality of life, and healthcare utilization patterns after traumatic spinal cord injury (tSCI). SETTING: Community setting, Atlantic Canada. METHODS: An ambispective study of data collected on a subset of individuals enrolled in the Rick Hansen Spinal Cord Injury Registry (RHSCIR) from 2012 to 2018. Outcomes were analyzed using two measures of rurality: postal codes at community follow-up (rural versus urban) and residential travel distance to the nearest RHSCIR facility (>100 km versus ≤100 km). Outcomes studied included the Craig Hospital Inventory of Environmental Factors-Short Form (CHIEF-SF), Short Form-36 Version 2 (SF36v2), Life Satisfaction Questionnaire (LISAT-11), Spinal Cord Independence Measure (SCIM), secondary health complications and healthcare utilization patterns. Outcomes were assessed 9 to 24 months post-discharge from initial hospitalization. RESULTS: 104 participants were studied, 21 rural and 83 urban based on postal codes at community follow-up. 59 participants lived more than 100 km away from the nearest RHSCIR facility, while 45 participants lived within 100 km. Individuals from urban area codes reported a greater magnitude of perceived barriers on the policies and work/school subscales of the CHIEF-SF. No differences in function, quality of life, and healthcare utilization patterns according to the measures of rurality were observed. Individuals living >100 km from the nearest RHSCIR facility reported greater rates of sexual dysfunction. CONCLUSIONS: Despite differences in environmental barriers, individuals from urban and rural locations in Eastern Canada reported similar health outcomes and quality of life after tSCI.

Introduction: Multimorbidity, defined as the coexistence of two or more health conditions, is common in persons with spinal cord injury (SCI). Network analysis is a powerful tool to visualize and examine the relationship within complex systems. We utilized network analysis to explore the relationship between 30 secondary health conditions (SHCs) and health outcomes in persons with traumatic (TSCI) and non-traumatic SCI (NTSCI). The study objectives were to (1) apply network models to the 2011-2012 Canadian SCI Community Survey dataset to identify key variables linking the SHCs measured by the Multimorbidity Index-30 (MMI-30) to healthcare utilization (HCU), health status, and quality of life (QoL), (2) create a short form of the MMI-30 based on network analysis, and (3) compare the network-derived MMI to the MMI-30 in persons with TSCI and NTSCI. Methods: Three network models (Gaussian Graphical, Ising, and Mixed Graphical) were created and analyzed using standard network measures (e.g., network centrality). Data analyzed included demographic and injury variables (e.g., age, sex, region of residence, date, injury severity), multimorbidity (using MMI-30), HCU (using the 7-item HCU questionnaire and classified as "felt needed care was not received" [HCU-FNCNR]), health status (using the 12-item Short Form survey [SF-12] Physical and Mental Component Summary [PCS-12 and MCS-12] score), and QoL (using the 11-item Life Satisfaction questionnaire [LiSAT-11] first question and a single item QoL measure). Results: Network analysis of 1,549 participants (TSCI: 1137 and NTSCI: 412) revealed strong connections between the independent nodes (30 SHCs) and the dependent nodes (HCU-FNCNR, PCS-12, MCS-12, LiSAT-11, and the QoL score). Additionally, network models identified that cancer, deep vein thrombosis/pulmonary embolism, diabetes, high blood pressure, and liver disease were isolated. Logistic regression analysis indicated the network-derived MMI-25 correlated with all health outcome measures (p <0.001) and was comparable to the MMI-30. Discussion: The network-derived MMI-25 was comparable to the MMI-30 and was associated with inadequate HCU, lower health status, and poor QoL. The MMI-25 shows promise as a follow-up screening tool to identify persons living with SCI at risk of having poor health outcomes.
ABSTRACT
Background: People of Aboriginal (Indigenous) ancestry are more likely to experience traumatic spinal cord injury (TSCI) than other Canadians; however, outcome studies are limited. This study aims to compare Aboriginal and non-Aboriginal populations with acute TSCI with respect to preinjury baseline characteristics, injury severity, treatment, outcomes and length of stay. Methods: This was a retrospective analysis of participants with a TSCI who were enrolled in the prospective Rick Hansen Spinal Cord Injury Registry (RHSCIR), Saskatoon site (Royal University Hospital), between Feb. 13, 2010, and Dec. 17, 2016. Demographic, injury and management data were assessed to identify any differences between the populations. Results: Of the 159 patients admitted to Royal University Hospital with an acute TSCI during the study period, 62 provided consent and were included in the study. Of these, 21 self-identified as Aboriginal (33.9%) and 41 as non-Aboriginal (66.1%) on treatment intake forms. Compared with non-Aboriginal participants, Aboriginal participants were younger, had fewer medical comorbidities, had a similar severity of neurologic injury and had similar clinical outcomes. However, the time to discharge to the community was significantly longer for Aboriginal participants (median 104.0 v. 34.0 d, p = 0.016). Although 35% of non-Aboriginal participants were discharged home from the acute care site, no Aboriginal participants were transferred home directly. Conclusion: This study suggests a need for better allocation of resources for transition to the community for Aboriginal people with a TSCI in Saskatchewan. We plan to assess outcomes from TSCI for Aboriginal people across Canada.
Contexte: Au Canada, les personnes d'origine autochtone sont plus susceptibles que les autres de vivre un traumatisme médullaire. Malgré cela, il y a peu d'études sur les conséquences de cet événement. Notre étude visait à comparer les cas de traumatisme médullaire aigu dans les populations autochtones et non autochtones sur plusieurs plans : les caractéristiques initiales des patients, la gravité du traumatisme, la nature du traitement, les issues cliniques et la durée de séjour. Méthodes: Nous avons fait une analyse rétrospective des dossiers de personnes ajoutées au Rick Hansen Spinal Cord Injury Registry (RHSCIR) [Registre des traumatismes médullaires Rick Hansen] entre le 13 février 2010 et le 17 décembre 2016 pour l'établissement de Saskatoon (l'Hôpital universitaire Royal). Nous avons comparé les renseignements de base des patients ainsi que les données sur le traumatisme et la prise en charge afin de cerner toute différence entre les populations. Résultats: Sur les 159 traumatisés médullaires admis à l'Hôpital universitaire Royal pendant la période à l'étude, 62 ont consenti à l'utilisation de leurs données. Parmi eux, 21 s'étaient identifiés comme Autochtones (33,9 %) sur le formulaire d'hospitalisation, et 41 comme non-Autochtones (66,1 %). Par rapport aux non-Autochtones, les Autochtones étaient plus jeunes, avaient moins de comorbidités, présentaient une atteinte neurologique de gravité comparable et connaissaient à peu près le même tableau clinique. Toutefois, le délai avant leur retour en communauté était significativement plus long (médiane : 104,0 jours contre 34,0 jours; p = 0,016). Aucun participant autochtone n'a été renvoyé directement à la maison, alors que 35 % des participants non autochtones sont retournés chez eux en quittant les soins de première ligne. Conclusion: Cette étude montre qu'il faut améliorer la répartition des ressources de retour dans la communauté pour les traumatisés médullaires autochtones de la Saskatchewan. Enfin, nous comptons examiner les répercussions cliniques du traumatisme médullaire chez les Autochtones de partout au Canada.

BACKGROUND: To optimize traumatic spinal cord injury (tSCI) care, administrative and clinical linked data are required to describe the patient's journey. OBJECTIVES: To describe the methods and progress to deterministically link SCI data from multiple databases across the SCI continuum in British Columbia (BC) and Ontario (ON) to answer epidemiological and health service research questions. METHODS: Patients with tSCI will be identified from the administrative Hospital Discharge Abstract Database using International Classification of Diseases (ICD) codes from Population Data BC and ICES data repositories in BC and ON, respectively. Admissions for tSCI will range between 1995-2017 for BC and 2009-2017 for ON. Linkage will occur with multiple administrative data holdings from Population Data BC and ICES to create the "Admin SCI Cohorts." Clinical data from the Rick Hansen SCI Registry (and VerteBase in BC) will be transferred to Population Data BC and ICES. Linkage of the clinical data with the incident cases and administrative data at Population Data BC and ICES will create subsets of patients referred to as the "Clinical SCI Cohorts" for BC and ON. Deidentified patient-level linked data sets will be uploaded to a secure research environment for analysis. Data validation will include several steps, and data analysis plans will be created for each research question. DISCUSSION: The creation of provincially linked tSCI data sets is unique; both clinical and administrative data are included to inform the optimization of care across the SCI continuum. Methods and lessons learned will inform future data-linking projects and care initiatives.

Timely access and ongoing delivery of care and therapeutic interventions is needed to maximize recovery and function after traumatic spinal cord injury (tSCI). To ensure these decisions are evidence-based, access to consistent, reliable, and valid sources of clinical data is required. The Access to Care and Timing Model used data from the Rick Hansen SCI Registry (RHSCIR) to generate a simulation of healthcare delivery for persons after tSCI and to test scenarios aimed at improving outcomes and reducing the economic burden of SCI. Through model development, we identified knowledge gaps and challenges in the literature and current health outcomes data collection throughout the continuum of SCI care. The objectives of this article were to describe these gaps and to provide recommendations for bridging them. Accurate information on injury severity after tSCI was hindered by difficulties in conducting neurological assessments and classifications of SCI (e.g., timing), variations in reporting, and the lack of a validated SCI-specific measure of associated injuries. There was also limited availability of reliable data on patient factors such as multi-morbidity and patient-reported measures. Knowledge gaps related to structures (e.g., protocols) and processes (e.g., costs) at each phase of care have prevented comprehensive evaluation of system performance. Addressing these knowledge gaps will enhance comparative and cost-effectiveness evaluations to inform decision-making and standards of care. Recommendations to do so were: standardize data element collection and facilitate database linkages, validate and adopt more outcome measures for SCI, and increase opportunities for collaborations with stakeholders from diverse backgrounds.

Return to living at home is an important patient-reported outcome following traumatic spinal cord injury (tSCI). Specialized inpatient rehabilitation assists such patients in maximizing function and independence. Our project aim was to describe those patients receiving specialized rehabilitation after tSCI in Canada, and to determine if such rehabilitation improved the likelihood of returning home. This cohort study utilized data from the Rick Hansen Spinal Cord Injury Registry (RHSCIR) to identify patients with tSCI discharged from 1 of 18 participating acute specialized spine facilities between 2011 and 2015 to either 1 of 13 participating specialized rehabilitation facilities, or to another discharge destination. To determine if specialized rehabilitation affected likelihood of returning home, multiple logistic regressions and propensity score matchings were performed to account for age at injury, gender, neurological severity and level, acute length of stay (LOS), and region of residence. The χ2 test was used to compare rate of return home between matched groups. Of the 1599 patients included, 71% received specialized rehabilitation. Receiving specialized rehabilitation was a significant and strong predictor of return to home after controlling for covariates (adjusted odds ratio = 3.1; 95% confidence interval [CI], 1.6-5.9). The rate of return to home was significantly higher in the matched rehabilitation group than the no rehabilitation group (98% vs. 87%, p = 0.0004). For the matched patients, an extra 11 patients returned home for every 100 patients receiving specialized rehabilitation. However, effect of age on returning home requires further investigation. Improving access to specialized rehabilitation could potentially reduce discharges to nursing homes or other non-home destinations.

Current research indicates that more than half of patients with traumatic spinal cord injury (tSCI) experience delays in transfer and receive surgery >24 h post-injury. The objectives of this study were to determine the geographic distribution of tSCI in Canada relative to specialized treatment facilities, to assess clinical and logistical factors at play for indirect admissions to those facilities, and to explore differences in current time to admission and simulated scenarios in an attempt to assess the potential impact of changes to triage protocols. This study included data from 876 patients with tSCI enrolled in the prospectively collected acute Rick Hansen Spinal Cord Injury Registry (RHSCIR) between January 1, 2010 and December 31, 2013 for whom there were data on the location of their injury. Patients transported directly to a RHSCIR acute facility were more likely to reach the facility within 1 h of injury, whereas those transported indirectly were more likely to arrive 7 h later. Considering the injuries occurring within 40 km of a RHSCIR acute facility (n = 323), 249 patients (77%) were directly and 74 (23%) were indirectly admitted. In the multivariate regression analysis, only older age and longer road distance remained significantly associated with being indirectly admitted to a RHSCIR facility. Compared with the current status, the median time to admission decreased by 20% (3.5 h) in the 100% direct admission scenario, and increased by 102% (8.9 h) in the 100% indirect admission scenario.
ABSTRACT
PURPOSE: Alpha blockade has been well described clinically for expulsion of distal ureteral stone. However, the in-vivo effects of α-blockade on ureteral dynamics during stone passage are not clear. We studied the effects of oral alfuzosin on ureteral pressure and peristalsis in a distally obstructed porcine ureter. METHODS: Twenty-four female domestic swine (75-82 kg) were incorporated into the study. The study was powered to detect a 30% difference in distal ureteral pressure, with a secondary endpoint of frequency of ureteral peristalsis. The animals were divided into four equal groups: a control group without α-blockade or ureteral obstruction, a group with α-blockade and no ureteral obstruction, a cohort without α-blockade but with distal ureteral obstruction, and a group with α-blockade and distal obstruction. Peristalsis was measured by a magnetic sensor and ureteral pressure through a 5F ureteral balloon catheter. Observations were recorded for 10-minute intervals every hour for 5 consecutive hours. RESULTS: There was increase in ureteral pressure and peristaltic rate with distal ureteral obstruction (p < 0.01). Alpha blockade did not produce significant changes in the above parameters with or without ureteral obstruction compared with the nonmedicated groups. We observed a 0.2 mm Hg lower increase in change of ureteral pressure during peristalsis compared with resting ureteral pressure (delta pressure) in the treated obstructed model (95% confidence interval: -0.55 -0.10; p = 0.06). CONCLUSIONS: In the porcine model, alfuzosin appears to decrease the delta pressure in the distal ureter during obstruction; however, statistical significance was not reached. Further investigation into the in-vivo physiology of medical expulsive therapy is warranted.
