Epidemiology of traumatic spinal cord injury in Finland

A comparison between the shoulder shifting test and seated reaching test by bland-altman plot: A pilot study

BACKGROUND

The Seated Reach Test (SRT) is an assessment tool for evaluating the sitting balance of individuals with a spinal cord injury (SCI). We developed the Shoulder Shifting Test (SST), which is a tool for measuring the reaching distance of individuals with difficulty in raising their arms, such as individuals with tetraplegia.

OBJECTIVE

To investigate the agreement between the SST and the SRT and the usefulness of the SST.

SUBJECTS AND METHODS

Sixteen subjects with SCI (age 52.9 ± 13.0 yrs; four with tetraplegia) performed the SST and the SRT. We determined the correlation coefficient to determine the relationship between the two tests. A Bland-Altman analysis was performed to confirm the systematic error, and the relative error (RE) was used to determine the compatibility of the two tests in three directions (front, right, left). We assessed the SST's usefulness by determining how many of 47 subjects (age 59.6 ± 13.6 yrs; 23 with tetraplegia) could not perform the SRT and how many could perform the SST.

RESULTS

The tests were strongly correlated. No systematic errors between the tests were observed. In all three directions, >75% of the subjects had an RE <20%. Eleven of the 47 subjects with SCI were unable to perform either test. Four to ten of the 36 subjects performed the SST due to the difficulty in raising their arms.

CONCLUSION

The SST was compatible with the SRT, and the sitting balance of more individuals with SCI could be assessed by the combination of these tests.

Spinal cord injury etiology, severity, and care in East Asia: a cross-sectional analysis of the International Spinal Cord Society Database Project

STUDY DESIGN

Cross-sectional study.

OBJECTIVES

To evaluate etiologic factors associated with spinal cord injury (SCI) severity and to identify predictive factors of reduction in SCI severity in six countries.

SETTING

SCI centers in Bangladesh, India, Malaysia, Nepal, Sri Lanka, and Thailand.

METHODS

Data from centers collected between October 2015 and February 2021 were analyzed using descriptive statistics and logistic regression.

RESULTS

Among 2634 individuals, the leading cause of SCIs was falls (n = 1410, 54%); most occurred from ≥1 meter (n = 1078). Most single-level neurological injuries occurred in the thoracic region (n = 977, 39%). Greater than half of SCIs (n = 1423, 54%) were graded American Spinal Injury Association Impairment Scale (AIS) A. Thoracic SCIs accounted for 53% (n = 757) of all one-level AIS A SCIs. The percentage of thoracic SCIs graded AIS A (78%) was significantly higher than high cervical (52%), low cervical (48%), lumbar (24%), and sacral (31%) SCIs (p < 0.001). Regression analyses isolated predictive factors both of SCI severity and inpatient improvement. Four factors predicted severity: age, neurological level, etiology, and country of residence. Four factors predicted improvement: age, neurological level, AIS grade on intake, and country of residence.

CONCLUSIONS

Findings can be used by healthcare providers and public health agencies in these countries to inform the public of the risk of SCI due to falls. Future studies should examine the social and occupational milieux of falls. Country-to-country comparisons of prehospital and inpatient care are also justified. Fall prevention policies can encourage the use of safety equipment when performing tasks at heights ≥1 meter.

The impact of COVID-19 and associated lockdowns on traumatic spinal cord injury incidence: a population based study

STUDY DESIGN

Natural experiment OBJECTIVES: To determine whether COVID-19 restrictions were associated with changes in the incidence of traumatic spinal cord injury (TSCI) in Scotland.

SETTING

The Queen Elizabeth National Spinal Injuries Unit (QENSIU), the sole provider of treatment for TSCI in Scotland.

METHODS

Time series analysis of all admissions for TSCI between 1st January 2015 and 31st August 2022.

RESULTS

Over the 8-year study period, 745 patients were admitted to the QENSIU with a TSCI. Interrupted time series analysis showed that level 3 and 4 COVID-19 lockdown restrictions (the most severe levels) were associated with lower incidence of TSCI (RR 0.63, CI% CI 0.47, 0.82, p < 0.001). The associations were stronger in people aged over 45 (additive interaction p = 0.001), males (additive interaction p = 0.01) and non-tetraplegia (additive interaction p = 0.002). The incidence of TSCI due to deliberate self-harm was higher (0.41 versus 0.23 per month) during restrictions.

CONCLUSIONS

Overall, TSCI incidence reduced in Scotland when lockdowns were implemented, presumably due to lower engagement in risky activities. The increase in TSCI due to deliberate self-harm may reflect increased mental health problems and social isolation and should be anticipated and targeted in future pandemics. The change in incidence during the COVID-19 pandemic may have an economic impact and see a temporary reduction in the burden on health and social care. The results of this study will be useful for resource planning in future pandemics.

A systematic review and meta-analysis of the global epidemiology of pediatric traumatic spinal cord injuries

Despite being relatively rare, pediatric traumatic spinal cord injury (TSCI) is a debilitating event with high morbidity and long-term damage and dependency. This study aims to provide insight on the epidemiological characteristics of pediatric TSCI worldwide. The studies were included if they provided data for the pediatric population with the diagnosis of TSCI. Information sources included PubMed, Embase, Web of Science, and Scopus. All databases were searched from 1990 to April 2023. The quality of included studies was evaluated by Joanna Briggs Institute Critical Appraisal Tools. The results of the meta-analysis were presented as forest plots. PROSPERO Registration code: CRD42020189757. We identified 87 studies from 18 developed and 11 developing countries. Of the 87 studies evaluated, 52 studies were considered medium quality, 27 studies were considered high quality, and 8 studies were considered low quality. In developed countries, the proportion of TSCIs occurring in patients aged 0-15 years was 3% (95% CI: 2.2%; 3.9%), while in developing countries, it was 4.5% (95% CI: 2.8%; 6.4%). In developed countries, the pooled incidence of pediatric TSCI was 4.3/millions of children aged 0-15/year (95% CI: 3.1; 6.0/millions children aged 0-15/year) and boys comprised 67% (95% CI: 63%; 70%) of cases. The most prevalent level of injury was cervical (50% [95% CI: 41%; 58%]). The frequency of SCI Without Obvious Radiological Abnormality (SCIWORA) was 35% (95% CI: 18%; 54%) among children 0-17 years. The most common etiology in developed countries was transport injuries (50% [95% CI: 42%; 57%]), while in developing countries falls were the leading cause (31% [95% CI: 20%; 42%]). The most important limitation of our study was the heterogeneity of studies in reporting age subgroups that hindered us from age-specific analyses.   Conclusion: Our study provided accurate estimates for the epidemiology of pediatric TSCI. We observed a higher proportion of pediatric TSCI cases in developing countries compared to developed countries. Furthermore, we identified distinct epidemiological characteristics of pediatric TSCI when compared to adult cases and variations between developing and developed countries. Recognizing these unique features allows for the implementation of cost-effective preventive strategies aimed at reducing the incidence and burden of TSCI in children. What is Known: • Pediatric Traumatic Spinal Cord Injury (TSCI) can have profound physical and social consequences for affected children, their families, and society as a whole. • Epidemiological insights are vital for they provide the data and understanding needed to the identification of vulnerable populations, aiding in the development of targeted prevention strategies and effective resource allocation. What is New: • The estimated incidence of pediatric TSCI in developed countries is 4.3 cases per million children aged 0-15. The proportion of pediatric TSCI cases in relation to all-age TSCI cases is 3% in developed countries and 4.5% in developing countries. • The etiology of TSCI in pediatric cases differs between developing and developed countries. In developed countries, transport injuries are the most prevalent cause of pediatric TSCI, while falls are the least common cause. Conversely, in developing countries, falls are the leading cause of pediatric TSCI.

An update to pain management after spinal cord injury: from pharmacology to circRNAs

Neuropathic pain (NP) following a spinal cord injury (SCI) is often hard to control and therapies should be focused on the physical, psychological, behavioral, social, and environmental factors that may contribute to chronic sensory symptoms. Novel therapeutic treatments for NP management should be based on the combination of pharmacological and nonpharmacological options. Some of them are addressed in this review with a focus on mechanisms and novel treatments. Several reports demonstrated an aberrant expression of non-coding RNAs (ncRNAs) that may represent key regulatory factors with a crucial role in the pathophysiology of NP and as potential diagnostic biomarkers. This review analyses the latest evidence for cellular and molecular mechanisms associated with the role of circular RNAs (circRNAs) in the management of pain after SCI. Advantages in the use of circRNA are their stability (up to 48 h), and specificity as sponges of different miRNAs related to SCI and nerve injury. The present review discusses novel data about deregulated circRNAs (up or downregulated) that sponge miRNAs, and promote cellular and molecular interactions with mRNAs and proteins. This data support the concept that circRNAs could be considered as novel potential therapeutic targets for NP management especially after spinal cord injuries.

Validity of the trunk assessment scale for spinal cord injury (TASS) and the trunk control test in individuals with spinal cord injury

BACKGROUND

The Trunk Assessment Scale for Spinal Cord Injury (TASS) and the Trunk Control Test for individuals with a Spinal Cord Injury (TCT-SCI) are highly reliable assessment tools for evaluating the trunk function of individuals with SCIs. However, the potential differences in the validity of these two scales are unclear.

OBJECTIVES

To evaluate the criterion validity of the TASS and the construct validity of the TASS and TCT-SCI.

PARTICIPANTS AND METHODS

We evaluated 30 individuals with SCIs (age 63.8 ± 10.7 yrs, 17 with tetraplegia). To evaluate criterion validity, we calculated Spearman's rho between the TASS and the gold standard (the TCT-SCI). To determine construct validity, we used the following hypothesis testing approaches: (i) calculating Spearman's rho between each scale and the upper and lower extremity motor scores (UEMS, LEMS), the Walking Index for SCI-II (WISCI-II), and the motor score of the Functional Independence Measure (mFIM); and (ii) determining the cut-off point for identifying ambulators with SCIs (≥ 3 points on item 12 of Spinal Cord Independent Measure III) by a receiver operating characteristics analysis.

RESULTS

A moderate correlation was confirmed between the TASS and the TCT-SCI (r = 0.68). Construct validity was supported by six of the eight prior hypotheses. The cut-off points for identifying ambulators with SCIs were 26 points (TASS) and 18 points (TCT-SCI).

CONCLUSION

Our results indicate that the contents of the TASS and the TCT-SCI might reflect the epidemiological characteristics of the populations in which they were developed.

Prognosis of Cervical Diffuse Idiopathic Skeletal Hyperostosis-Related Spine Injuries in Elderly Patients: Analyses of Both Fracture and Spinal Cord Injury Without Fracture

STUDY DESIGN

Retrospective multicenter study.

OBJECTIVE

The purpose of this study was to compare the prognosis of elderly patients with injuries related to cervical diffuse idiopathic skeletal hyperostosis (cDISH) to matched control for each group, with and without fractures.

METHODS

The current multicenter study was a retrospective analysis of 140 patients aged 65 years or older with cDISH-related cervical spine injuries; 106 fractures and 34 spinal cord injuries without fracture were identified. Propensity score-matched cohorts from 1363 patients without cDISH were generated and compared. Logistic regression analysis was performed to determine the risk of early mortality for patients with cDISH-related injury.

RESULTS

Patients with cDISH-related injuries with fracture did not differ significantly in the incidence of each complication and ambulation or severity of paralysis compared to matched controls. In patients with cDISH-related injury without fracture, those who were nonambulatory at discharge comprised 55% vs 34% of controls, indicating significantly poorer ambulation in those with cDISH-related injuries (P = .023). There was no significant difference in the incidence of complications and ambulation or paralysis severity at 6 months as compared with controls. Fourteen patients died within 3 months. Logistic regression analysis identified complete paralysis (odds ratio [OR] 36.99) and age (OR 1.24) as significant risk factors for mortality.

CONCLUSIONS

The current study showed no significant differences in the incidence of complications, ambulation outcomes between patients with cDISH-related injury with fracture and matched controls, and that the ambulation at discharge for patients with cDISH-related injury without fractures were significantly inferior to those of matched controls.

Spinal injury in major trauma: Epidemiology of 1104 cases from an Italian first level trauma center

INTRODUCTION

Traumatic spinal injuries are frequent and their management is debated, especially in major trauma patients. This study aims to describe a large population of major trauma patients with vertebral fractures to improve prevention measures and fracture management.

PATIENTS AND METHODS

Retrospective analysis of 6274 trauma patients prospectively collected between October 2010 and October 2020. Collected data include demographics, mechanism of trauma, type of imaging, fracture morphology, associated injuries, injury severity score (ISS), survival, and death timing. The statistical analysis focused on mechanism of trauma and the search of predictive factors for critical fractures.

RESULTS

Patients showed a mean age of 47 years and 72.5% were males. Trauma included 59.9% of road accidents and 35.1% of falls. 30.7% patients had at least a severe fracture, while 17.2% had fractures in multiple spinal regions. 13.7% fractures were complicated by spinal cord injury (SCI). The mean ISS of the total population was 26.4 (SD 16.3), with 70.7% patients having an ISS≥16. There is a higher rate of severe fractures in fall cases (40.1%) compared to RA (21.9% to 26.3%). The probability of a severe fracture increased by 164% in the case of fall and by 77% in presence of AIS≥3 associated injury of head/neck while reduced by 34% in presence of extremities associated injuries. Multiple level injuries increased with ISS rise and in the case of extremities associated injuries. The probability of a severe upper cervical fracture increased by 5.95 times in the presence of facial associated injuries. The mean length of stay was 24.7 days and 9.6% of patients died.

CONCLUSIONS

In Italy, road accidents are still the most frequent trauma mechanism and cause more cervico-thoracic fractures, while falls cause more lumbar fractures. Spinal cord injuries represent an indicator of more severe trauma. In motorcyclists or fallers/jumpers, there is a higher risk of severe fractures. When a spinal injury is diagnosed, the probability of a second vertebral fracture is consistent. These data could help the decisional workflow in the management of major trauma patients with vertebral injury.

Incidence and mortality of spinal cord injury from 2008 to 2020: a retrospective population-based cohort study in the Piedmont Region, Italy

STUDY DESIGN

Retrospective population-based cohort study.

OBJECTIVES

To determine the incidence and mortality of spinal cord injuries (SCI) in the Piedmont Region of Northwestern Italy.

SETTING

Publicly-funded SCI rehabilitation centres in the Piedmont Region.

METHODS

Administrative databases were used to identify individuals at their first admission to a SCI rehabilitation centre from January 1st, 2008 to December 31st, 2020. Cases were stratified by age and aetiology (traumatic SCI, TSCI; non-traumatic SCI, NTSCI). Age- and aetiology-specific incidence rate and person-year mortality rates were calculated for each year. Case lethality was reported as deaths among prevalent cases for each year.

RESULTS

A total of 892 cases were identified (56.4% TSCI). The average annual crude incidence rate was 17.9 per million population, decreasing from 26.0 in 2008 to 10.8 in 2020. Young adults and the elderly represented the majority of TSCI and NTSCI cases, respectively. Of the 235 individuals who died during the study period, 58.3% had NTSCI. The mortality rate per 1000 person-years decreased from 16.3 in 2009 to 8.5 in 2020, while case lethality more than tripled (from 17.2 in 2009 to 57.1 in 2020).

CONCLUSIONS

We identified a decreasing trend in SCI incidence and mortality rates, with an increased case lethality over the study period, especially in NTSCI. Given these changes in the epidemiology of SCI, community services offered after rehabilitation should be strengthened to enhance their effectiveness and contribute to increased survival in this population.

Epidemiological characteristics of 1,806 patients with traumatic spinal cord injury: A retrospective study

Background

Traumatic spinal cord injury (TSCI) is a type of highly disabling central nervous system trauma. In this study, we investigated the epidemiological characteristics of 1,806 TSCI patients and compared the characteristics of patients with traumatic cervical spinal cord injury (TCSCI) caused by cervical fracture/dislocation and disc herniation/bulging.

Methods

We retrospectively reviewed the hospital records of 1,806 TSCI patients. The detailed information included gender, marital status, occupation, age, neurological level of injury, etiology, American Spinal Injury Association (ASIA) grade, combined injuries, complications, treatment, the interval between admission and surgery, intubation/tracheostomy requirement, and the length of hospital stay.

Results

Cervical spinal cord injury (CSCI) was the most common injury. Compared to non-CSCI cases, patients with TCSCI were older, and more likely to suffer from tetraplegia and require intubation/tracheostomy, but had fewer other injuries or complications and a shorter length of hospital stay. Compared to patients with cervical fracture/dislocation, those with TCSCI caused by disc herniation/bulging were older and more likely to suffer from paraplegia, but required intubation/tracheostomy less frequently, exhibited fewer other injuries and complications, and required shorter hospitalization.

Conclusions

Men, married individuals, manual laborers, and individuals aged 31-75 years had the highest risk of TSCI. Patients with TCSCI tended to have a shorter length of hospital stay than patients with non-CSCI. More attention should be paid to the other injuries and complications of non-CSCI patients, which may increase the length of hospital stay and delay rehabilitation. Compared to patients with cervical disc herniation, the patients with fracture/dislocation tended to be younger, but prognosis was severely compromised by tetraplegia, a greater need for intubation/tracheostomy, additional injuries, and complications.

Temporal changes in demographic and injury characteristics of traumatic spinal cord injuries in Nordic countries - a systematic review with meta-analysis

STUDY DESIGN

Systematic review with meta-analysis.

OBJECTIVES

To explore temporal changes in incidence rates, demographic and injury characteristics of incident traumatic spinal cord injury (TSCI) in Nordic countries.

METHODS

Peer-reviewed publications and periodic reports about epidemiology of TSCI in the Nordic countries (Denmark, Finland, Iceland, Norway, Sweden) are identified, reviewed and included in the meta-analysis. Data are stratified into 20-year intervals to allow for chronological comparisons. Pooled estimates are derived using random effects meta-analysis.

RESULTS

Twenty-three data sources are included presenting a total of 5416 cases. The pooled incidence rate for 2001-2020 is 15.4 cases/million/year compared to 17.6 and 18.3 cases/million/year during the two previous 20-year intervals. The proportion of cases with TSCI in the 15-29 age-group decreases from 50% (1961-1980) to 20% (2001-2020), while it increases from 9% to 35% in 60+ age-group. Transportation-related injuries decrease from 44% (1961-1980) to 27% (2001-2020). Conversely, fall-related injuries increase from 32% (1961-1980) to 46% (2001-2020). The proportion of individuals with incomplete tetraplegia increases from 31% (1961-1980) to 43% (2001-2020), while complete paraplegia decreases from 25% to 16%.

CONCLUSION

The characteristics of TSCI in the Nordic countries have changed drastically over the last six decades, in line with clinical experiences, and limited research evidence from other countries. These changes indicate the need for adapting research focus, prevention strategies, design and provision of care, rehabilitation and community services towards older individuals, fall-related injuries, and incomplete injuries in Nordic countries and other settings internationally where such changes occur.

Responsiveness and minimal clinically important differences of the Trunk Assessment Scale for Spinal Cord injury (TASS)

OBJECTIVE

To confirm the responsiveness and minimal clinically important differences (MCIDs) of the Trunk Assessment Scale for Spinal Cord Injury (TASS).

PARTICIPANTS AND METHODS

We evaluated 48 Japanese individuals with spinal cord injury (SCI) (age 64.1 ± 10.4 yrs, 28 with tetraplegia) admitted to two institutions at admission, at 1 month of hospitalization, and at discharge with the TASS, the Trunk Control Test in individuals with an SCI (TCT-SCI) motor score, the Functional Independence Measure motor score (mFIM), and the Global Rating of Change Scale (GRCS). We assessed the TASS responsiveness by determining the correlation coefficients for the changes in the TASS' and other assessments' scores. We calculated the MCIDs by five anchor-based methods.

RESULTS

The changes in the TASS and those in the other assessments were weakly correlated at 1 month and moderately correlated at discharge. The TASS MCIDs were observed at 1 month and at discharge.

CONCLUSION

Our findings confirmed that the change in TASS scores had weak-to-moderate correlations with the changes in the participants' upper- and lower-limb function and activities of daily living. Using the MCID for the TASS determined by anchor-based methods may lead to a better interpretation of changes in the trunk function of individuals with SCIs.

Predicting motor function recovery in cervical spinal cord injury-induced complete paralysis with reflex response

STUDY DESIGN

A retrospective clinical study.

OBJECTIVE

To elucidate the usefulness of the patellar tendon reflex (PTR), bulbocavernosus reflex (BCR), and plantar response (PR) as factors in the prognostic prediction of motor function in complete paralysis due to cervical spinal cord injuries (CSCIs) at the acute phase.

SETTING

Department of Orthopedic Surgery, Spinal Injuries Center, Japan.

METHODS

99 patients assessed as the American Spinal Injury Association Impairment Scale (AIS) grade A (AIS A) were included in this study. The PTR, BCR, and PR were evaluated respectively as positive or negative at the time of injury. We classified the patients into two groups based on their neurological recovery at 3 months after injury: "recovered" group was defined as AIS C, D, or E; "non-recovered" group was defined as AIS A or B.

RESULTS

Eight patients demonstrated positive PTR, while 91 demonstrated negative. Three out of eight patients with positive PTR (37.5%) were R group, while 83 out of 91 patients with negative PTR (91.2%) were N group. A significant difference was observed (p = 0.043). For BCR, no significant difference was observed (p > 0.05). Twenty-six patients demonstrated positive PTR, while 73 demonstrated negative. Nine out of twenty-six patients with positive PR (34.6%) were R group, while 71 out of 73 patients with negative PR (97.3%) were N group. A significant difference was observed (p = 0.000068).

CONCLUSION

The PTR and PR are useful for poor prognostic prediction of motor function in CSCI at the acute phase.

Reliability and minimal detectable change of the Trunk Assessment Scale for Spinal Cord Injury (TASS) and the trunk control test for individuals with spinal cord injury

STUDY DESIGN

Cross-sectional study.

OBJECTIVES

To evaluate the reliability and calculate the measurement error of the Trunk Assessment Scale for Spinal Cord Injury (TASS) and trunk control test (TCT-SCI) in individuals with spinal cord injury (SCI).

SETTING

Rehabilitation Hospital in Japan.

METHODS

The evaluations of TASS and TCT-SCI for individuals with SCI were video-recorded. The inter-rater reliability (two physiotherapists) was confirmed using the videos. ICC (2,1), kappa coefficient (κ) were used to determine the reliability of the total score and each item. Each minimal detectable change (MDC) was calculated.

RESULTS

The TASS and TCT-SCI total scores showed excellent inter-rater reliability (ICC = 0.99, and 1.00). The kappa coefficients of TASS were acceptable to excellent for 8 items (κ = 0.76-1.00), below acceptable for 1 item (κ = 0.62). The kappa coefficients of TCT-SCI were excellent for 12 items (κ = 0.83-1.00), below acceptable for 1 item (κ = 0.68). The inter-rater MDC of the TASS total score was 4.07 points, and the MDC of the TCT-SCI total score was 1.13 points. The intra-rater MDC of the TASS total score was 3.86 points.

CONCLUSION

Both TASS and TCT-SCI showed high reliability. Differences of less than four points in TASS and one point in TCT-SCI were interpreted as measurement errors between the two raters.

An update on the roles of circular RNAs in spinal cord injury

Spinal cord injury (SCI) is a disabling condition for which therapeutic options are limited. Increasing number of microarray and next-generation sequencing studies have demonstrated that SCI coincides with altered expression of circular RNAs (circRNAs) in the damaged tissue. Emerging functional evidence further pinpointed specific differentially expressed circRNAs (e.g., circ-HIPK3, cicRNA.7079, circRNA_01477, circRNA-2960, and circ_0001723) for their effects on cellular processes relevant to SCI repair and regeneration, including neuronal apoptosis, astrocyte activation, and neuroinflammation, via sponging SCI-related microRNAs. Although circRNAs and their target microRNAs appear to be good candidates for therapeutic exploitation in SCI, further investigation into the efficient delivery of these regulatory molecules in a cell-type specific manner is a pre-requisite for translating these basic discoveries into clinical benefits.

Epidemiological profile of 338 traumatic spinal cord injury cases in Shandong province, China

STUDY DESIGN

Hospital-based retrospective review.

OBJECTIVE

To describe the epidemiological characteristics of traumatic spinal cord injury (TSCI) in Liaocheng, China.

SETTING

Liaocheng People's Hospital.

METHODS

Medical records of 338 persons with TSCI admitted to Liaocheng People's Hospital from 2013 to 2017 were reviewed. The detailed information included gender, age, marital status, occupation, time, etiology, level of injury, ASIA grade, spinal stenosis, concomitant injury, treatment, length of stay.

RESULTS

Over this period, the mean age (SD) of persons with TSCI was 50.1 (14.1) years, and the male/female ratio was 3.1:1. 96.4% of all were married. The leading cause was fall, followed by motor vehicle accident (MVA). The most common level of injury was the cervical cord. ASIA grade D and A injuries were the most common, accounting for 48.5 and 29.3% respectively. Among the concomitant injuries, spinal fractures were the most common. Within 24 h, 91.1% of individuals with TSCI arrived hospital, 63.3% of all accepted surgery.

CONCLUSION

The results showed that fall and MVA were the two main causes, so we should focused on preventing fall and reducing MVA. Cervical spinal stenosis can increase the risk of TSCI, so education should be provided to this population to raise their risk awareness. In addition, timely treatment was critical for TSCI, but the data showed that rescue process was not standard, so it was necessary for medical staff to popularize professional knowledge.

Epidemiology of traumatic spinal cord injuries in Colombia

STUDY DESIGN

Retrospective cohort study.

OBJECTIVES

To determine the incidence and characteristics of newly injured individuals admitted to a traumatic spinal cord injury (TSCI) referral center during a 4-year period.

SETTING

University Hospital of Valle, Cali, Colombia.

METHODS

Individuals were identified, and their data was recorded based on the International Spinal Cord Injury Core Data Set. The outcome of interest was the American Spinal Injury Association Impairment Scale (AIS) grade at the last follow-up.

RESULTS

There were 491 individuals admitted in the 4-year period. The mean annual incidence of TSCI was 56.27 per million inhabitants. Considering TSCI in individuals exclusively from Cali, the mean annual incidence was 27.78 per million. The leading cause of TSCI was interpersonal violence (47.25%) and falls (33.60%). There was a strong correlation between AIS grade at admission and last follow-up. The most common AIS grade at the last follow-up was E (34.01%) caused mostly by falls (57.48%), followed by A (31.16%) caused mostly by interpersonal violence (76.27%). The reported employment rate dropped from 75.56% to 18.94% before and after TSCI (p < 0.05). AIS grade A was associated with more post-injury complications (p < 0.05).

CONCLUSIONS

This is the first cohort study in Colombia describing the incidence and AIS grades of individuals with TSCI from a trauma referral center. Interpersonal violence was overrepresented in this population. Future research should include the evaluation of prevention strategies, as well as research on interventions towards quality improvement in patient care and post-discharge services especially for individuals with AIS grade A.
