Epidemiology of Work-Related Traumatic Spinal Cord Injury: An Analysis of Workers' Compensation Claims in Korea, 2011-2019

OBJECTIVE

We aimed to identify the incidence and burden of work-related traumatic spinal cord injury (wrTSCI) in Korea in the 10-year period from 2010 to 2019.

METHODS

We used nationwide workers' compensation insurance data. The study population comprised industrially injured workers with TSCI diagnosis codes. The annual incidence of wrTSCI (number per million workers) was calculated.

RESULTS

The mean annual incidence of wrTSCI was 22.8/1,000,000 (95% confidence interval, 20.5 to 25.0), and the mean total cost per claim was 231.40 million KRW. The incidence of TSCI in the cervical region was the highest (13.1/1,000,000; 95% confidence interval, 11.4 to 14.9), and most cases were in the construction industry (47.3%).

CONCLUSION

These findings can help identify specific at-risk groups and facilitate the development of prevention strategies.

The impact of major occupational injuries on professional reintegration. A Portuguese medico-legal contribution

Occupational injuries represent an enormous economic impact for victims, respective families, involved institutions and all the community due to professional outcomes. Thus, it is of the utmost importance that medico-legal personal injury assessment and the posterior follow-up of these victims, may allow their concrete damage repair, considering the victims' needs fulfilment and professional reintegration, whenever possible. The main objective of this study is to reflect on the role that legal medicine can play in promoting the professional reintegration of victims of major occupational accidents through the analysis of occupational injuries cases considering the medico-legal examinations performed. A retrospective study was conducted using medico-legal major occupational injuries cases (Partial Permanent Disability ≥40%). Data were collected from two medico-legal assessment moments: (a) personal injury assessment homologated by a labour court 4.8 years on average after occupational injury; (b) medico-legal follow-up for needs and/or Partial Permanent Disability adjustments performed 18.9 years on average after occupational injury. The final sample includes 103 cases. The results showed that in major occupational accidents, permanent long-term outcomes were principally associated with neurological (62.1%) and orthopaedic (52.4%) sequelae. Permanent professional damage parameters assigned by the labour court included Partial Permanent Disability (23.3%), Permanent Absolute Disability for Regular Work (41.7%) and Permanent Absolute Disability for Any Work (35%). Three-dimensional methodology is helpful in predicting Partial Permanent Disability and Permanent Absolute Disability for Any Work. However, three-dimensional methodology did not reveal correlations with Permanent Absolute Disability for Regular Work, and currently 65% of the victims who were considered able to work by the labour court are not professionally active. Thus, these major cases deserve a more detailed medico-legal approach based on concrete information about the professional reality of each victim, especially cases with an eventual Permanent Absolute Disability for Regular Work. Medico-legal Injury Assessment must be based on concrete aspects of the victim's professional reality and not only on permanent disability tables. This calls for an articulation between all institutions working with the victim of occupational injuries and legal medicine to promote recovery and the necessary measures to assure professional rehabilitation.

Does restraint status in motor vehicle crash with rollover predict the need for trauma team presence on arrival? An ATOMAC study

PURPOSE

Restraint status has not been combined with mechanistic criteria for trauma team activation. This study aims to assess the relationship between motor vehicle crash rollover (MVC-R) mechanism with and without proper restraint and need for trauma team activation.

METHODS

Patients <16years old involved in an MVC-R between November 2007 and November 2012 at 6 Level 1 pediatric trauma centers were included. Restraint status, the need for transfusion or intervention in the emergency department (ED), hospital and intensive care length of stay and mortality were assessed.

RESULTS

Of 690 cases reviewed, 48% were improperly restrained. Improperly restrained children were more likely to require intubation (OR 10.24; 95% CI 2.42 to 91.69), receive blood in the ED (OR 4.06; 95% CI 1.43 to 14.17) and require intensive care (ICU) (OR; 3.11; 95% CI 1.96 to 4.93) than the properly restrained group. The improperly restrained group had a longer hospital length of stay (p<0.001), and a higher mortality (3.4% vs. 0.8%; OR 4.09; 95% CI 1.07 to 23.02) than the properly restrained group.

CONCLUSION

Unrestrained children in MVC-R had higher injury severity and were significantly more likely to need urgent interventions compared to properly restrained children. This supports a modification to include restraint status with the rollover criterion for trauma team activation.

Work-Related Injuries: Injury Characteristics, Survival, and Age Effect

Work-related injuries impose a significant burden on society. The goal of this study was to delineate the epidemiology and the effect of age on type and mortality after occupational injuries. Patients 16 years of age or older sustaining work-related injuries were identified from the National Trauma Databank 12.0. The study population was stratified into four age groups: 16 to 35, 36 to 55, 56 to 65, and older than 65 years old. The demographic characteristics, type of injury, mechanism of injury, setting of injury, use of alcohol or other illicit drugs, and mortality were analyzed and related to age strata. Overall 67,658 patients were identified. There were 27,125 (40.1%) patients in the age group 16 to 35 years, 30,090 (44.5%) in the group 36 to 55 years, 6,618 (9.8%) in the group 56 to 65 years, and 3,825 (5.7%) older than 65 years. The injury severity increased significantly with age. Elderly patients were significantly more likely to sustain intracranial hemorrhages, spinal, and other skeletal injuries. The overall mortality was 2.9 per cent (1938) with the latter increasing significantly in a stepwise fashion with progressing age, becoming sixfold higher in patients older than 65 years (OR, 6.18; 95% CI, 4.78 to 7.80; P < 0.001). Our examination illustrates the associations between occupational injury and significant mortality that warrant intervention for mortality reduction. There is a stepwise-adjusted increase in mortality with progressing age.

Work-related traumatic spinal cord lesions in Chile, a 20-year epidemiological analysis

STUDY DESIGN

Retrospective cohort study.

OBJECTIVE

To describe the characteristics of patients with work-related traumatic spinal cord injuries (TSCI) in Chile.

SETTING

Hospital del Trabajador in Santiago, Santiago, Chile.

METHODS

Patients suffering from TSCI incurred at the workplace from 1986 to 2005 were identified through records of the Asociación Chilena de Seguridad (ACHS, Chilean Safety Association).

RESULTS

The medical records of 173 patients, 172 men and 1 woman, were analyzed. The yearly average incidence was 7.8 per million workers. Age at TSCI onset was 38.2 ± 12.1 years. The principal external causes for TSCI incurred at the workplace were falls from a height in 86 cases (49.7%) and trauma blows to the vertebral spine in 61 cases (35.3 %). More falls occurred in the field construction, and other traumas occurred as a result of traumatic blows caused by tree trunks and stones in forestry and mining sectors. Mortality in this series was 8.7%, and the worst prognosis was for older patients with complete tetraplegia. The paraplegia:tetraplegia ratio was 3.2:1.

CONCLUSIONS

The characteristics of workplace TSCI are specific to this population. It is important therefore to develop prevention programs for specific work-related TSCI.

The importance of vehicle rollover as a field triage criterion

BACKGROUND

The objective of this article was to review the importance of vehicle rollover as a field triage criterion. In 1987, field triage criteria were developed by the American College of Surgeons Committee on Trauma that have been propagated repeatedly over the subsequent 20+ years. The field triage decision scheme is based on abnormal physiology, obvious abnormal anatomy, mechanism of injury likely to result in severe injury, and other factors (age, etc.) and was supported by available science at that time. In 2005, the triage scheme was revised by a committee, and vehicle rollover as a crash scene triage criterion was dropped in 2006.

METHODS

The medical literature and data from the Department of Transportation/National Highway Traffic Safety Administration (NHTSA) Fatal Accident Reporting System and the National Automotive Sampling System were analyzed to determine the contribution of rollover to morbidity and mortality.

RESULTS

Vehicle rollovers represent a small but significant percentage of crashes; of the almost 12 million vehicle crashes reported by NHTSA in 2004, only 2.4% were rollovers, but these accounted for one-third of all crash-related occupant deaths and about 25,000 serious injuries every year. Rollovers are associated with the second highest number of vehicle occupant deaths by crash mode, three times the risk of injury when compared with other impact directions (p < 0.0001), specific types of injury such as head and spinal cord injuries, and a risk of death >15 times the risk in nonrollover crashes.

CONCLUSION

The data and literature unequivocally show a strong and disproportionate association between vehicle rollover and injury severity and death. Because it is difficult to devise simple, accurate decision rules for point of wounding and vehicle crash scene triage, simple, powerful relationships should be used when possible. Thus, the exclusion of rollover as a triage criterion seems to be ill advised.

Review of spinal cord injuries in Ireland

STUDY DESIGN

Prospective data collection on all patients with spinal cord injury (SCI) admitted for a comprehensive management programme.

OBJECTIVES

To examine the epidemiology of SCI in Ireland over 1 year.

SETTING

Ireland's National Spinal Cord Injury Centre.

METHODS

Systematic data collection on all patients admitted with SCI for management.

RESULTS

A total of 46 patients (40 males) were admitted from January to December 2000; median age was 37 years (range 6-82 years). In all, 23 of the patients presented with cervical injuries, 19 patients had thoracic injuries. In all, 18 patients had complete injuries (American spinal injuries association (ASIA)). Motor vehicle collisions were the cause of 50% of SCI.

CONCLUSIONS

The incidence of SCI in Ireland is 13.1 per million population. Demographic data from this study can go towards improving care for patients with SCI and also in the prevention of SCI.

An Italian survey of traumatic spinal cord injury. The Gruppo Italiano Studio Epidemiologico Mielolesioni study11No commercial party having a direct financial interest in the results of the research supporting this article has or will confer a benefit upon the author(s) or upon any organization with which the author(s) is/are associated

OBJECTIVE

To describe the etiology, clinical presentation, complications, outcome indicators, and links between emergency and acute intervention and rehabilitation of patients with traumatic spinal cord injury (SCI).

DESIGN

Multicenter prospective study involving patients with SCI discharged, after rehabilitative care, between February 1, 1997, and January 31, 1999.

SETTING

Thirty-two Italian hospitals involved in SCI rehabilitation.

PARTICIPANTS

Six hundred eighty-four patients with traumatic SCI on their first admission to a rehabilitation center.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Neurologic improvement (NI), bladder autonomy, feelings of dependency, and destination were evaluated on discharge. Pressure ulcers on admission, time from injury to admission, and length of stay (LOS) were considered as indirect measures of the effectiveness of the health system.

RESULTS

Traumatic etiology had a male-to-female ratio of 4:1 (548:136). Collision on the road was the main cause of traumatic injury (53.8%). Mean time from injury to admission was 36.8 days; 126 patients (18%) were admitted within the first week after injury. Mean LOS was 135.5 days. In 184 patients (26.9%), a pressure ulcer was present on admission. On discharge, NI was recorded in 179 patients (26.2%), whereas 446 (65%) and 418 (61%) had bladder and bowel autonomy, respectively, and 560 (81.9%) returned home. In the multivariate analysis, independent variables predicting poor outcome (NI, feelings of dependency, sphincter autonomy, discharge to home, LOS) were related both to the lesion (completeness, cervical involvement) and to the indicators of health service organization (time from injury to admission, complications on admission and during stay).

CONCLUSIONS

Our focus on the etiology of traumatic SCI showed that efforts should be made to prevent collisions on the road. Our study also highlights problems in the comprehensive management of patients with SCI in Italy. Better organization could help reduce the time from injury to admission, the number of complications on admission, and LOS, and it could help improve rehabilitation outcome.
