Which Trauma Severity Scores Are Useful in Predicting Pediatric Mortality?

BACKGROUND AND OBJECTIVES: Trauma is the leading cause of death in children. Several trauma severity scores exist: the shock index (SI), age-adjusted SI (SIPA), reverse SI (rSI), and rSI multiplied by Glasgow Coma Score (rSIG). However, it is unknown which is the best predictor of clinical outcomes in children. Our goal was to determine the association between trauma severity scores and mortality in pediatric trauma. DESIGN AND METHODS: A multicenter retrospective study was performed using the 2015 US National Trauma Data Bank, including patients 1 to 18 years old and excluding patients with unknown emergency department dispositions. The scores were calculated using initial emergency department parameters. Descriptive analysis was carried out. Variables were stratified by outcome (hospital mortality). Then, for each trauma score, a multivariate logistic regression was conducted to determine its association with mortality. RESULTS: A total of 67,098 patients with a mean age of 11 ±5 years were included. Majority of the patients were male (66%) and had an injury severity score <15 (87%). Eighty-four percent of patients were admitted: 15% to the intensive care unit and 17% directly to the operating room. The mortality at hospital discharge was 3%.There was a statistically significant association between SI, rSI, rSIG, and mortality ( P < 0.05). The highest adjusted odds ratio for mortality corresponded to rSIG, followed by rSI then SI (8.51, 1.9, and 1.3, respectively). CONCLUSION: Several trauma scores may help predict mortality in children with trauma, the best being rSIG. Introduction of these scores in algorithms for pediatric trauma evaluations can impact clinical decision-making.

Misdiagnosis of Pediatric Concussions in the Emergency Department: A Retrospective Study.

OBJECTIVE: We aimed to determine the rate and predictors of correctly diagnosed concussions in the pediatric emergency department and to describe the characteristics, presentation, and management of concussions in children presenting for minor head injury. METHODS: We included 186 patients aged 5 to 18 years presenting within 24 hours of minor head injuries and met our diagnostic criteria for concussion. We compared patients correctly diagnosed with a concussion with those who were not. Our main outcome was the rate and predictors of misdiagnoses. RESULTS: Of the patients, 5.4% were correctly diagnosed. Amnesia was the only variable associated with correct diagnoses (40.0% vs 10.2%, P = 0.02). The most common mechanism of injury was fall (8.4%); the most frequent symptoms were nausea/vomiting (42.5%), and 48.4% had a brain computed tomography scan done. CONCLUSIONS: The high rate of concussion misdiagnosis puts into question the usability of current concussion guidelines, their accuracy, and barriers to translation into clinical practice.

Lead screening in children presenting to three hospitals in Lebanon.

BACKGROUND: Lead damages most body organs and its effects are most profound in children. In a study in Beirut in 2003, before banning the leaded gasoline, 79% of the participants showed blood lead levels (BLLs) higher than 5 µg/dL. The prevalence of lead exposure in Lebanon after the ban on leaded gasoline has not been studied. This study assessed the BLL in Lebanese children aged 1-6 years. METHODS: This cross-sectional study was conducted in three hospitals in Beirut. The children's BLLs were tested, and their caregiver completed a questionnaire to identify subgroups at risk of exposure. Participants were provided with a WHO brochure highlighting the risks of lead. RESULTS: Ninety children with a mean age of 3.5±1.5 years were enrolled in the study and had a mean BLL of 1.1±0.7 µg/dL, with all values being below 5.0 µg/dL, showing a marked decrease in BLL compared with the mean BLL before the ban on leaded gasoline in 2002. Having a father or a mother with a college degree (p=0.01 and p=0.035, respectively) and having a monthly household income greater than $1000 (p=0.021) were associated with significantly lower BLL. Having more rooms at home and residing close to construction sites were associated with a significantly lower BLL (p=0.001 and p=0.026, respectively). Residing in a house aged >40 years and receiving traditional remedies were associated with a significantly higher BLL (p=0.009 and p<0.0001, respectively). CONCLUSION: BLLs have declined among Lebanese children and this could be attributed to multiple factors including the ban of leaded gasoline. It would be beneficial to conduct a larger study with a nationally representative sample to better characterise the BLL.
