Variation in patterns of hospitalization and associated resource use among children with spinal cord injury in the U.S.

Trauma is a leading cause of mortality and morbidity among children in the U.S. There is paucity of data on the triage of children with spinal cord injury (SCI) to definitive trauma care, and it is unknown if clinical outcomes and resource utilization for children hospitalized with SCI vary according to the settings where trauma care is provided. The study was conducted to describe recent patterns of emergency department (ED) evaluation for paediatric SCI in the U.S., and to characterize outcomes and resource use for children hospitalized at non-trauma centres versus trauma centres. Secondary analysis of a national database on injured children 0-20 years evaluated at U.S. EDs and either hospitalized or released, in 2009-2012. In-hospital mortality, duration of stay, and overall charges, were compared according to trauma centre status of the treating hospital. Of an estimated 67 million annual paediatric visits to the ED for trauma evaluation nationally in 2009-2012, 2317 had SCI. Majority (87%) of children evaluated for SCI were under 6 years of age, and boys comprised 73% of the visits. Injuries were caused mainly by motor vehicle accidents, falls, non-transport-related accidents, and firearms. The South census region had the most ED visits and hospitalizations. Majority (92%) of the most severely injured was evaluated at trauma centres, and more visits to trauma centres (81% vs. 18%, p=0.022) resulted in hospitalization. Among an estimated 1570 hospitalizations of children with SCI from the ED nationally, children at trauma centres were more likely to have major injuries (67% vs. 44%, p=0.001), similar mortality, longer average hospital stay, and higher charges, compared with children hospitalized at non-trauma centres. Significant demographic and geographical variation exists in national patterns of hospital care for paediatric SCI. Higher severity of patient injury was associated with concomitantly higher hospital resource use at trauma centres.

The Epidemiology of Emergency Department Trauma Discharges in the United States.

Injury-related morbidity and mortality is an important emergency medicine and public health challenge in the United States. Here we describe the epidemiology of traumatic injury presenting to U.S. emergency departments (EDs), define changes in types and causes of injury among the elderly and the young, characterize the role of trauma centers and teaching hospitals in providing emergency trauma care, and estimate the overall economic burden of treating such injuries. We conducted a secondary retrospective, repeated cross-sectional study of the Nationwide Emergency Department Data Sample (NEDS), the largest all-payer ED survey database in the United States. Main outcomes and measures were survey-adjusted counts, proportions, means, and rates with associated standard errors (SEs) and 95% confidence intervals. We plotted annual age-stratified ED discharge rates for traumatic injury and present tables of proportions of common injuries and external causes. We modeled the association of Level I or II trauma center care with injury fatality using a multivariable survey-adjusted logistic regression analysis that controlled for age, sex, injury severity, comorbid diagnoses, and teaching hospital status. There were 181,194,431 (SE = 4,234) traumatic injury discharges from U.S. EDs between 2006 and 2012. There was a mean year-to-year decrease of 143 (95% CI = -184.3 to -68.5) visits per 100,000 U.S. population during the study period. The all-age, all-cause case-fatality rate for traumatic injuries across U.S. EDs during the study period was 0.17% (SE = 0.001%). The case-fatality rate for the most severely injured averaged 4.8% (SE = 0.001%), and severely injured patients were nearly four times as likely to be seen in Level I or II trauma centers (relative risk = 3.9 [95% CI = 3.7 to 4.1]). The unadjusted risk ratio, based on group counts, for the association of Level I or II trauma centers with mortality was risk ratio = 4.9 (95% CI = 4.5 to 5.3); however, after sex, age, injury severity, and comorbidities were accounted for, Level I or II trauma centers were not associated with an increased risk of fatality (odds ratio = 0.96 [95% CI = 0.79 to 1.18]). There were notable changes at the extremes of age in types and causes of ED discharges for traumatic injury between 2009 and 2012. Age-stratified rates of diagnoses of traumatic brain injury increased 29.5% (SE = 2.6%) for adults older than 85 and increased 44.9% (SE = 1.3%) for children younger than 18. Firearm-related injuries increased 31.7% (SE = 0.2%) in children 5 years and younger. The total inflation-adjusted cost of ED injury care in the United States between 2006 and 2012 was $99.75 billion (SE = $0.03 billion). Emergency departments are a sensitive barometer of the continuing impact of traumatic injury as an important cause of morbidity and mortality in the United States. Level I or II trauma centers remain a bulwark against the tide of severe trauma in the United States, but the types and causes of traumatic injury in the United States are changing in consequential ways, particularly at the extremes of age, with traumatic brain injuries and firearm-related trauma presenting increased challenges.
