The Epidemiology of Childhood and Adolescent Traumatic Spinal Cord Injury in the United States: 2007–2010

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.

Nationwide emergency department visits for pediatric traumatic spinal cord injury in the United States, 2016-2020

Introduction

Traumatic spinal cord injury (tSCI) is a debilitating neurological condition resulting in lifelong disability for many individuals. The primary objectives of our study were to describe national trends in incident emergency department (ED) visits for tSCI among children (less than 21 years) in the United States, and to determine the proportion of visits that resulted in immediate hospitalization each year, including stratified by age and sex. Secondary objectives were to examine associations between select characteristics and hospitalization following tSCI, as well as to assess sports-related tSCIs over time, including by individual sport and geographic region.

Methods

We used the Healthcare Cost and Utilization Project Nationwide Emergency Department Sample to identify ED visits among children between January 2016 and December 2020 for incident tSCI. Diagnosis codes were used to identify tSCI and sports-related injury etiologies. Census Bureau data were used to approximate annual rates of pediatric ED visits for tSCI per 100,000 children. Unconditional logistic regression modeling assessed whether select factors were associated with hospital admission.

Results

We found that the annual ED visit rate for tSCI remained relatively stable between 2016 and 2020, with approximately 2,200 new all-cause pediatric ED visits for tSCI annually. Roughly 70% of ED visits for tSCI resulted in hospitalization; most ED visits for tSCI were by older children (15-20 years) and males, who were also more often admitted to the hospital. Notable secondary findings included: (a) compared with older children (15-20 years), younger children (10-14 years) were less likely to be hospitalized immediately following an ED visit for tSCI; (b) patient sex and race were not associated with hospital admission; and (c) American tackle football was the leading cause of sports-related ED visits for tSCI among children. Our findings also suggest that the proportion of sports-related tSCI ED visits may have increased in recent years.

Discussion

Future research should further examine trends in the underlying etiologies of pediatric tSCI, while assessing the effectiveness of new and existing interventions aimed at tSCI prevention.

Global Epidemiology of Pediatric Traumatic Spine Injury: A Systematic Review and Meta-Analysis

OBJECTIVE

Traumatic spine injury (TSI) leads to significant morbidity and mortality in children. However, the global epidemiology of pediatric TSI is currently unknown. We conducted a systematic review and meta-analysis to estimate the global incidence of pediatric TSI and the burden of cases.

METHODS

PubMed, Embase, and Scopus were searched for reports in June 2021 and updated in March 2023 with no restrictions on language or year of publication. A meta-analysis was conducted to estimate the global incidence of pediatric TSI and, subsequently, the number of cases of pediatric TSI worldwide and the proportion requiring spine surgery.

RESULTS

Of 6557 studies, 25 met the inclusion criteria. Road traffic accidents (64%) were responsible for most cases reported in the literature, followed by falls (18%). The global incidence of TSI in children aged ≤20 years was estimated to be 14.24 of 100,000 children, or 375,734 children, with an estimated 114,975 requiring spine surgery. Across the World Bank income classification groups, lower middle-income countries had the highest pediatric TSI case burden (186,886 cases, with 57,187 requiring spine surgery). Across the World Health Organization regions, countries in the Southeast Asia region had the largest number of projected cases at 88,566, with 27,101 requiring surgical management, followed closely by the African region, with 87,235 projected cases and 26,694 requiring surgical management.

CONCLUSIONS

Pediatric TSI represents a large healthcare burden globally. Interventions targeting both injury prevention and strengthening of neurosurgical capacity, especially in low resource settings, are needed to address this global health challenge.

Dual diagnosis of TBI and SCI: an epidemiological study in the pediatric population

Introduction

Dual diagnosis (DD) with traumatic brain injury (TBI) and spinal cord injury (SCI) poses clinical and rehabilitation challenges. While comorbid TBI is common among adults with SCI, little is known about the epidemiology in the pediatric population. The primary objective of this study was to evaluate the prevalence of TBI among children in the United States hospitalized with SCI. Secondary objectives were to compare children hospitalized with DD with those with isolated SCI with regards to age, gender, race, hospital length of stay, and hospital charges.

Methods

A retrospective analysis of hospital discharges among children aged 0-18 years occurring between 2016-2018 from U.S. hospitals participating in the Kids' Inpatient Database. ICD-10 codes were used to identify cases of SCI, which were then categorized by the presence or absence of comorbid TBI.

Results

38.8% of children hospitalized with SCI had a co-occurring TBI. While DD disproportionately occurred among male children (67% of cases), when compared with children with isolated SCI, those with DD were not significantly more likely to be male. They were more likely to be Caucasian. The mean age of children with DD (13.2 ± 5.6 years) was significantly less than that of children with isolated SCI (14.4 ± 4.3 years). DD was associated with longer average lengths of stay (6 versus 4 days) and increased mean total hospital charges ($124,198 versus $98,089) when compared to isolated SCI.

Conclusion

Comorbid TBI is prevalent among U.S. children hospitalized with SCI. Future research is needed to better delineate the impact of DD on mortality, quality of life, and functional outcomes.

Evaluation of Clinical Characteristics and Comorbid Conditions in Pediatric Traumatic Spinal Cord Injury Patients

Objective This study aimed to examine the demographic features and the most common comorbid conditions of pediatric traumatic spinal cord injury (SCI) patients who were admitted to Ankara Physical Therapy and Rehabilitation Training and Research Hospital's inpatient rehabilitation program. Materials and methods The demographic features, clinical features and cormorbid conditions of 147 pediatric traumatic SCI patients (age of injury 17 and under) who received an inpatient rehabilitation program in the hospital between 2009-2017 were retrospectively examined. Patients were divided into three groups according to the lesion location (cervical, thoracic, and lumbar); and into two groups according to the age of completing the development of osteoligamentous structures in the vertebral column (group 1: ≤ 10 years and group 2: >10 years), and the evaluated data were compared. Results 73.5% of the patients were male, the average age of injury was 13.60 ± 4.19 years, and the average duration of the disease was 11.17 ± 20.80 months. The most common etiological reason was falls from height (34.7%), and the most common level of injury was the thoracic region (49%). The most common comorbid conditions after SCI were found to be neurogenic bladder (91.2%), spasticity (41.54%), and neuropathic pain (29.3%). It was determined that neurogenic bladder was seen less in the lumbar region (p<0.001). Urinary tract infection was found more in the cervical group (p=0.004). In Group 1 (0-10 years), the median disease duration was longer, and the rate of thoracic region injury and complete injury was higher (p<0.05); in Group 2 (11-17 years), the rate of having stabilization operation after the injury was significantly higher (p<0.001). Conclusion It is crucial to prevent the etiological reasons in pediatric traumatic SCI patients, to treat the arising comorbid conditions in the early period, to take protective measures, and to follow up the patients regularly when necessary.

Pediatric Spina Bifida and Spinal Cord Injury

Pediatric spina bifida (SB) and spinal cord injury (SCI) are unfortunately common in our society, and their unique findings and comorbidities warrant special consideration. This manuscript will discuss the epidemiology, pathophysiology, prevention, and management strategies for children growing and developing with these unique neuromuscular disorders. Growth and development of the maturing child places them at high risk of spinal cord tethering, syringomyelia, ascending paralysis, pressure injuries, and orthopedic abnormalities that must be addressed frequently and judiciously. Similarly, proper neurogenic bladder and neurogenic bowel management is essential not just for medical safety, but also for optimal psychosocial integration into the child’s expanding social circle.

Pediatric Traumatic Spinal Cord Injury in the United States: A National Inpatient Analysis

BACKGROUND

Traumatic spinal cord injury (tSCI) is a debilitating neurological condition often associated with lifelong disability. Despite this, there are limited data on pediatric tSCI epidemiology in the United States.

OBJECTIVES

Our primary objective was to estimate tSCI hospitalization rates among children, including by age, sex, and race. Secondary objectives were to characterize tSCI hospitalizations and examine associations between sociodemographic characteristics and tSCI etiology.

METHODS

We used the 2016 Kids' Inpatient Database to examine tSCI hospitalizations among children (<21 years). Descriptive statistics were used to report individual and care setting characteristics for initial tSCI hospitalizations. We used Census Bureau data to estimate tSCI hospitalization rates (number of pediatric tSCI hospitalizations / number of US children) and logistic regression modeling to assess associations between documented sociodemographic characteristics and injury etiology.

RESULTS

There were 1.48 tSCI admissions per 100,000 children; highest rates of hospitalization involved older (15-20 years), male, and Black children. Hospitalization involving male (adjusted odds ratio [AOR] 0.43; 95% CI, 0.33-0.58) or Black (AOR 0.37; 95% CI, 0.25-0.55) children were less likely to involve a motor traffic accident. Hospitalizations of Black children were significantly more likely to have a diagnosis of tSCI resulting from a firearm incident (AOR 18.97; 95% CI, 11.50-31.28) or assault (AOR 11.76; 95% CI, 6.75-20.50) compared with hospitalizations of White children.

CONCLUSION

Older, male, and Black children are disproportionately burdened by tSCI. Implementation of broad health policies over time may be most effective in reducing pediatric tSCI hospitalizations and preventable injuries.

Factors Associated With In-Hospital Outcomes of Traumatic Spinal Cord Injury: 10-year Analysis of the US National Inpatient Sample

INTRODUCTION

Traumatic spinal cord injury (SCI) is a life-altering event. Motor vehicle accidents and falls are common causes of traumatic SCI, and SCI outcomes may be affected by patients' ages and injury sites. This study aimed to investigate the factors associated with unfavorable in-hospital outcomes, focusing on the impact of patients' ages and SCI lesion sites.

METHODS

Data of 25,988 patients hospitalized with traumatic SCI in the US National Inpatient Sample (NIS) database from 2005 to 2014 were extracted and analyzed. Univariate and multivariate logistic regression analyses were performed to determine the factors associated with SCI outcomes, including in-hospital deaths, adverse discharge, and prolonged hospital stays.

RESULTS

Multivariate analysis revealed that the oldest ages (>65 years) were significantly associated with increased in-hospital mortality compared with the youngest ages at all lesion sites (cervical, odds ratio [OR]: 5.474, 95% confidence interval [CI]: 4.465 to 6.709; thoracic, OR: 5.940, 95% CI: 3.881 to 9.091; and lumbosacral, OR: 6.254, 95% CI: 2.920 to 13.394). Older ages were also significantly associated with increased adverse outcomes at all sites (cervical, OR: 2.460, 95% CI: 2.180 to 2.777; thoracic, OR: 2.347, 95% CI: 1.900 to 2.900; and lumbosacral, OR: 2.743, 95% CI: 2.133 to 3.527). Intermediate ages (35 to 64) were also significantly associated with increased in-hospital death and adverse discharge at cervical and thoracic SCIs, but not at lumbosacral sites.

DISCUSSION

For hospitalized patients with traumatic SCI, older age independently predicts worse in-hospital outcomes, with greatest effects seen in patients aged 65 years and older. Study findings suggest that extra vigilance and targeted management strategies are warranted in managing SCI patients aged 65 years and older during hospitalization.

Trends of traumatic spinal injury-related hospitalizations in Australian children over a 10-year period: a nationwide population-based cohort study

BACKGROUND CONTEXT

Despite its potential to cause serious and life-long disability or death, population-based data on traumatic spinal injury in pediatric populations is scarce.

PURPOSE

To quantify and describe the incidence and cost of hospitalizations for traumatic spinal injury among Australian children, and to examine the trend over a 10-year period.

STUDY DESIGN

Population-based retrospective cohort study.

PATIENT SAMPLE

Children aged ≤16 years who were hospitalized for traumatic spinal injury in Australia during 1 July 2002 to 30 June 2012.

OUTCOME MEASURES

Age-standardized hospital admission rates.

METHODS

This study used linked hospitalization and mortality data. Age-standardized hospitalization rates were calculated with 95% confidence intervals (CIs). Negative binomial regression was used to examine change in temporal trends in hospitalization rates.

RESULTS

There were 4,360 hospitalizations for pediatric traumatic spinal injury during the 10-year study period. Males and older children were more frequently hospitalized, and falls and road trauma accounted for almost three-quarters of hospitalizations. The average overall annual hospitalization rate was 9.43 (95% CI: 9.15-9.72) per 100,000 population, with an annual percent change of 1.2% (95% CI: -0.1% to 2.4%). There was an increase in the annual hospitalization rate for spinal dislocations, sprains, and strains (3.0% [95% CI: 0.8%-5.3%]) and among female children (1.7% [95% CI: 0.0%-3.4%]). The estimated total hospital treatment costs were AUD$43 million over the 10-year study period, with an estimated mean cost per child of AUD$9,867.

CONCLUSIONS

Pediatric traumatic spinal injury is associated with significant morbidity and mortality. The burden of hospitalized pediatric traumatic spinal injury in Australia is rising, in particular spinal dislocations, sprains, and strains among female children. Targeted prevention strategies are needed to reduce the burden of pediatric traumatic spinal injury. It is recommended that a coordinated national strategy for preventing childhood traumatic spinal injury is developed and implemented in Australia.

Spine Injuries in Child Abuse

BACKGROUND

Although rare, spinal injuries associated with abuse can have potentially devastating implications in the pediatric population. We analyzed the association of pediatric spine injury in abused children and determined the anatomic level of the spine affected, while also focusing on patient demographics, length of stay, and total hospital charges compared with spine patients without a diagnosis of abuse.

METHODS

A retrospective review of the Kids' Inpatient Database was conducted from 2000 to 2012 to identify pediatric patients (below 18 y) who sustained vertebral column fractures or spinal cord injuries. Patients with a documented diagnosis of abuse were identified using ICD-9-CM diagnosis codes. Our statistical models consisted of multivariate linear regressions that were adjusted for age, race, and sex.

RESULTS

There were 22,192 pediatric patients with a diagnosis of spinal cord or vertebral column injury during the study period, 116 (0.5%) of whom also had a documented diagnosis of abuse. The most common type of abuse was physical (75.9%). Compared with nonabused patients, abused patients were more likely to be below 2 years of age (OR=133.4; 95% CI, 89.5-198.8), female (OR=1.67; 95% CI, 1.16-2.41), and nonwhite (black: OR=3.86; 95% CI, 2.31-6.45; Hispanic: OR=2.86; 95% CI, 1.68-4.86; other: OR=2.33; 95% CI, 1.11-4.86). Abused patients also presented with an increased risk of thoracic (OR=2.57; 95% CI, 1.67-3.97) and lumbar (OR=1.67; 95% CI, 1.03-2.72) vertebral column fractures and had a multivariate-adjusted mean length of stay that was 62.2% longer (P<0.001) and mean total charges that were 52.9% higher (P<0.001) compared with nonabused patients. Furthermore, 19.7% of all pediatric spine patients under 2 years of age admitted during the study period belonged to the abused cohort.

CONCLUSIONS

Spine injuries are rare but can be found in the pediatric population. With an additional documented diagnosis of abuse, these injuries affect younger patients in the thoracolumbar region of the spine, and lead to longer lengths of stay and higher hospital costs when compared with nonabused patients. Because of these findings, physicians should maintain a higher level of suspicion of abuse in patients with spine injuries, especially patients under 2 years of age.

LEVEL OF EVIDENCE

Level III evidence-a case-control study.

U.S. Estimates of Pediatric Spinal Cord Injury: Implications for Clinical Care and Research Planning

The aim of this study was to provide accurate estimates and characterizations of children with spinal cord injuries (SCIs) and for the subset that are appropriate for inclusion in clinical trials. We identified children <18 years of age with SCI International Classifications of Diseases, Ninth Revision, Clinical Modification Codes (ICD-9-CM codes) from the 2006, 2009, and 2012 Kids' Inpatient Database. We excluded those with late effects, transfers to other hospitals, unspecified injury levels, and hospital stays <48 h. We then used conventional rationale to identify children who were eligible for SCI clinical trials. Over 3 years, 2484 children had SCI ICD-9-CM codes; 1342 had coding consistent with true SCI and 706 satisfied clinical trial inclusion criteria, yielding national estimates of 2013 and 1062, respectively. Of children with clinical trial eligible SCI, injuries were more common in the cervical region (66.1%), males (65.5%), older children (51.1% were 16-17 years old), and the South (49.8%). The majority were treated at urban teaching hospitals (84.6%); however, only 20.3% were treated at pediatric-specific centers. Of the 445 sample hospitals treating children with SCI, 66.3% treated just 1 child in the 3-year period. Children eligible for SCI clinical trials represented less than one third of children with SCI ICD-9-CM codes. These children were regionally localized to the South, with few receiving treatment at pediatric-specific centers or centers that frequently care for children with SCI. These findings highlight the importance of carefully assessing the national distribution of children with SCI, so that resources are appropriately allocated to optimize clinical care and research outcomes.

Epidemiology of Pediatric Traumatic and Acquired Nontraumatic Spinal Cord Injury in Ireland

Objective: To examine the epidemiology of pediatric traumatic (TSCI) and acquired nontraumatic spinal cord injury (NTSCI) in Ireland. There are few studies reporting pediatric TSCI incidence and fewer of pediatric NTSCI incidence, although there are several case reports. As there is a single specialist rehabilitation facility for these children, complete population-level data can be obtained. Method: Retrospective review of prospectively gathered data in the Patient Administration System of the National Rehabilitation Hospital of patients age 15 years or younger at the time of SCI onset. Information was retrieved on gender, age, etiology, level of injury/AIS. Population denominator was census results from 1996, 2002, 2006, and 2011, rolled forward. Results: Since 2000, 22 children have sustained TSCI and 26 have sustained NTSCI. Median (IQR) age at TSCI onset was 6.3 (4.4) years, and at NTSCI onset it was 7.3 (8.1) years. Most common TSCI etiology was transportation (n = 10; 45.5%), followed by surgical complications (n = 8; 36.4%); most common injury type was complete paraplegia (n = 12; 54.5%) followed by incomplete paraplegia (n = 5; 22.7%). Most common NTSCI etiology was transverse myelitis (n = 11; 42.3%) followed by vascular (n = 5; 20%); most common injury type was incomplete paraplegia (n = 17; 65.4%) followed by incomplete tetraplegia (n = 6; 24%). Incidence of TSCI ranged from 0 to 3.1 per million per year; incidence of NTSCI ranged from 0 to 6.5 per million per year. Conclusion: Incidence of SCI in Ireland seems similar to or slightly lower than other developed countries. Injury patterns are also similar, considering variations in reporting methods.

Distraction Injury of the Thoracic Spine With Spinal Cord Transection and Vascular Injury in a 5-Week-Old Infant Boy: A Case of Child Physical Abuse

Distraction injury of the spine with spinal cord transection and adjacent vascular injury is rarely described in the setting of child physical abuse. We report a 5-week-old infant boy who sustained these injuries after an abusive event. The clinical presentation, imaging findings, and recommended evaluation modalities are discussed. An overview of pediatric spinal column and vascular injuries secondary to physical abuse is given.

Body and Corporality in adolescents and young adults with spinal cord injury

OBJECTIVE

To describe the meaning given by adolescents and young adults to the changes in their bodies and corporality after a spinal cord injury.

METHODS

Qualitative study based on symbolic interactionism in which 12 adolescents and young adults, who had suffered spinal cord injury 6 months or more before, participated. The information was recollected through a series of in-depth interviews and field journals. The guidelines proposed by Corbin and Strauss were followed for the process of codification and categorization of the data.

RESULTS

Four categories were identified that describe the meanings given by participants to the changes in their bodies and corporality: Transformation of self-image, living with contradictions in the relationships with others, withstanding the burden of a disability and adapting to the new conditions.

CONCLUSION

The results allow for the comprehension of the meanings that are given by the people who have suffered a spinal cord lesion to their situation. This will in turn open the possibility of offering these people a better individual nursing care that focuses more on the particular needs, so that both they and their families can be helped on their way to adaptation to the new situation.

Epidemiology of Traumatic Spinal Cord Injury Among Persons Older Than 21 Years: A Population-Based Study in South Carolina, 1998-2012

BACKGROUND

A gap exists in the current knowledge regarding the epidemiology of traumatic spinal cord injury (TSCI) in a statewide population.

OBJECTIVE

To describe population-based epidemiology and trend of TSCI in persons 22 years and older in South Carolina over a 15-year period from 1998 through 2012.

METHODS

Data on patients with TSCI were obtained from ongoing statewide TSCI surveillance and follow-up registry. Deaths were ascertained by linking surveillance files and the multiple cause-of-death dataset. Descriptive analyses were completed, and incidence and mortality rates were calculated based on the civilian adult population of the state.

RESULTS

Over the 15 years, 3,365 persons with incident TSCI were discharged alive from acute care hospitalization, of whom 555 died during the period of observation. Age-standardized cumulative mortality rate was 14 per million, and the average incidence rate was estimated at 70.8 per million population per year. Age-standardized incidence rate of TSCI increased significantly from 66.9 in 1998 to 111.7 per million in 2012. Standardized incidence rates were significantly higher among non-Whites and males. Motor vehicle crashes and falls were the leading causes, accounting for nearly 70% of TSCI.

CONCLUSIONS

Standardized incidence and mortality rates of TSCI in South Carolina are higher than reported rates for the US population. Motor vehicle crashes and falls are the leading causes of TSCI. There was a significant increase in the overall trend of the incidence rates over the 15 years. A well-coordinated preventive strategy is needed to reduce incidence and improve survival of persons with TSCI.

Epidemiology of Aquatic and Recreational Water Sport Injuries: A Case-Control Analysis

The purposes of the current investigation are to evaluate the epidemiology of water sport injuries at a coastal tertiary trauma center and to determine the association of these activities with spinal column injury and to determine whether aquatic trauma injuries differ significantly from those that occur terrestrially. A retrospective review of a consecutive series of 105 patients with aquatic-based mechanisms of injury admitted to a Level II trauma center over a 3-year period, as well as a matched control cohort with terrestrial-based mechanisms of injury, was conducted. Patients were treated at a Level II trauma center from January 1, 2008, to December 31, 2010. All patients received a full trauma work-up on arrival. Patients were identified retrospectively from a prospectively collected database (N=5298). Eligible patients were identified from billing/coding data as having mechanisms of injury related to an aquatic setting. Patients were evaluated using standard trauma protocols. Spinal column and cord injury occurrence and differences between groups were reviewed. Personal watercrafts accounted for the majority of injuries (n=39). Cervical (33.3%), closed-head (25.7%), and thoracolumbar (21.9%) injuries accounted for the majority of injury types. The cervical spinal column and the spinal cord were at an increased risk of injury in the aquatic injury cohort (P<.0001). The current data show the high incidence of spinal column and cord injuries in this patient population relative to controls. Practitioners who care for trauma patients near an aquatic environment should be aware of the high prevalence of these injuries, with proper spinal cord preservation protocols in place to optimize outcome.

Factors associated with hospital admission for proximal humerus fracture

BACKGROUND

The number of inpatient admissions for proximal humerus fracture is increasing, but the factors that determine hospitalization are not well documented. We sought to identify predictors of hospital admission among individuals presenting to the emergency department (ED) with a fracture of the proximal humerus.

METHODS

Using the Nationwide Emergency Department Sample for 2010 and 2011, an estimated 285661 patients were identified and separated into those who were admitted to hospital (19%) and those who were discharged directly home (81%). Multivariable logistic regression modeling was used to identify independent predictors of hospital admission.

RESULTS

Factors associated with admission included increasing age and Charlson comorbidity index, ED visit on a weekday, Medicare and Medicaid insurance, open fracture, injury due to motor vehicle crash, polytrauma, urban teaching hospital, and residence in the Northeast. The lowest ratio of hospital admission to home discharge was noted for uninsured patients (0.09).

DISCUSSION

Factors unrelated to medical complexity such as insurance status, geographic region, timing of ED visit, and hospital type are associated with inpatient admission for proximal humerus fracture. Interventions to reduce variation in hospital admission and the influence of nonclinical factors merit attention.
