Basic is Better? An Assessment of National Outcomes in Prehospital Airway Management in Critical Acuity Pediatric Trauma

BACKGROUND

Consensus is lacking regarding prehospital airway management in pediatric trauma patients (PTPs).

OBJECTIVES

This retrospective study compared prehospital basic-airway procedures (B-AP) vs. advanced-AP (A-AP) among PTPs, comparing scene time, transport time, and improvement in acuity from scene to emergency department.

METHODS

The 2020 National Emergency Medical Services Information System was used to study patients 1-18 years old with prehospital AP. A-AP were compared with B-AP using chi-square, Wilcoxon rank sum, multivariable logistic, and linear regression models in terms of improvement in acuity, and transport and scene times.

RESULTS

The 3325 cases included 672 A-AP and 2653 B-AP; 39 esophageal combi- or dual lumen tubes, 48 laryngeal mask airways, and 585 orotracheal intubations. Overall failure rate: A-AP 8.77% vs B-AP 1.09% (p < 0.0001). Adjusted models identified reduction in scene time for B-AP vs. A-AP (estimate: 4 min 51 s, 95% confidence interval 9 min, 49 s-6 s; p = 0.01). B-APs were associated with improved acuity (odds ratio 1.19, 95% confidence interval 1.11-1.27; p < 0.001) after adjusting for Revised Trauma Score, provider type, urbanicity, time spent at scene, and demographic variables.

CONCLUSION

Prehospital B-APs were associated with shorter scene time and improvement in acuity compared with A-AP in PTPs. Variability in airway management practices across U.S. regions is high, leaving room for improvement in standardization of care and training.

Factors associated with pediatric trauma patients leaving against medical advice

BACKGROUND

Discharge against medical advice (AMA) leads to worse patient outcomes, increased readmission rates, and higher cost. However, AMA discharge has received limited study, particularly in pediatric trauma patients. Our objective was to explore the risk factors associated with leaving AMA in pediatric trauma patients.

METHODS

We performed a retrospective analysis on pediatric trauma patients from 2017 to 2019 using the National Trauma Data Bank. We examined patient characteristics including age (<18 years), race, sex, Glasgow Coma Scale, trauma type, primary payment methods, and Abbreviated Injury Scale. Multiple Logistic Regression models were utilized to determine characteristics associated with leaving AMA.

RESULTS

Of the 224,196 pediatric patients included in the study, 238 left AMA (0.1%). Our study showed black pediatric trauma patients were more likely to leave AMA compared to nonblack patients (OR 1.987, 95% CI 1.501 to 2.631). Patients with self-pay coverage were more likely to leave AMA than those with other insurance coverages (OR 1.759, 95% CI 1.183 to 2.614). Blunt trauma patients were more likely to leave AMA than those with penetrating trauma (OR 1.683, 95% CI 1.216 to 2.330). Every one-year increase in age led to 15% increase in odds of AMA discharge (OR 1.150, 95% CI 1.115 to 1.186). Pediatric patients with severe abdominal injuries were less likely to leave AMA compared to those with mild abdominal injuries (OR 0.271, 95% CI 0.111 to 0.657). Patients with severe lower extremity injury were less likely to leave AMA compared to those with mild lower extremity injuries (OR 0.258, 95% CI 0.127 to 0.522).

CONCLUSION

Race, insurance, injury type, and age play a role in AMA discharge of pediatric trauma patients. Black pediatric trauma patients have ∼ double the AMA discharge rate of nonblack patients. AMA discharge remains relevant, and addressing racial and socioeconomic factors provide opportunities for future interventions in pediatric trauma care.

Evaluation of outcome associated with feline trauma: A Veterinary Committee on Trauma registry study

OBJECTIVE

To evaluate outcome (survival to discharge) among trauma types (blunt, penetrating, both) in cats. Secondary objectives were to evaluate for associations between trauma type, injury severity, and the diagnostics and interventions selected by primary clinicians.

DESIGN

Retrospective evaluation of veterinary trauma registry data.

SETTING

Veterinary Committee on Trauma (VetCOT) veterinary trauma centers (VTCs).

ANIMALS

A total of 3895 feline trauma patients entered in the VetCOT trauma registry from April 1, 2017 to December 31, 2019.

INTERVENTIONS

Data collected included patient demographics, trauma type, Abdominal Fluid Score (AFS), Animal Trauma Triage (ATT) score, surgical intervention, glide sign on Thoracic Focused Assessment with Sonography for Trauma, Triage, and Tracking (TFAST), pleural effusion on TFAST, modified Glasgow Coma Scale (mGCS), and outcome (survival to discharge).

MEASUREMENTS AND MAIN RESULTS

Data from 3895 cats were collected over a 30-month period. Incidence of trauma types was as follows: blunt, 58% (95% confidence interval [CI]: 56%-59%); penetrating, 35% (95% CI: 34%-37%); and combination, 7.4% (95% CI: 6.7%-8.3%). Differences in survival incidence among the trauma types were identified: blunt, 80% (95% CI: 78%-81%); penetrating, 90% (95% CI: 89%-92%); and combined, 68% (95% CI: 63%-74%) (P < 0.01). Cats in the penetrating trauma group had the lowest proportion of severe injuries (6%) and highest proportion of mGCS of 18 (89%); cats with combined trauma had the highest proportion of severe injuries (26%) and lowest proportion of mGCS of 18 (63%). Point-of-care ultrasound and surgery were not performed in the majority of cases. When surgery was performed, the majority of blunt cases' procedures occurred in the operating room (79%), and the majority of penetrating cases' procedures were performed in the emergency room (81%).

CONCLUSIONS

Cats suffering from penetrating trauma had the best outcome (survival), lower ATT scores, and higher mGCS overall. Cats that sustained a component of blunt trauma had a lower survival rate, higher ATT scores, and the highest proportion of mGCS <18.

Comparison of clinical outcomes in cases of blunt, penetrating, and combination trauma in dogs: A VetCOT registry study

OBJECTIVE

To evaluate outcome (survival to discharge) among trauma types (blunt, penetrating, both) in dogs. The secondary objective was to evaluate if other trauma registry parameters differ between trauma types and influence survival.

DESIGN

Retrospective evaluation of veterinary trauma registry data.

SETTING

Veterinary Committee on Trauma (VetCOT) identified Veterinary Trauma Centers (VTCs).

ANIMALS

A total of 20,289 canine trauma patients with data entered in the VetCOT trauma registry from April 1, 2017 to December 31, 2019 INTERVENTIONS: None.

MEASUREMENTS AND MAIN RESULTS

Data were obtained from the VetCOT database and included patient demographics, trauma type (blunt, penetrating, both), Animal Trauma Triage (ATT) score, modified Glasgow Coma Scale (mGCS), abdominal fluid score (AFS), loss of glide sign on thoracic focused assessment with sonography for trauma (TFAST), pleural effusion on TFAST, surgical procedure performed and in what location (emergency room vs operating room), and outcome. Data from 20,289 dogs were collected over a 30-month period. The most common type of trauma was penetrating (10,816, 53.3%), followed by blunt (8360, 41.2%) and then combined blunt and penetrating trauma (1113, 5.5%). Dogs suffering only penetrating trauma had a 96.5% survival rate, blunt trauma had an 89.5% survival rate, and combined trauma had an 86.3% survival rate. Dogs suffering from both types of trauma had higher ATT scores, lower mGCS scores, and were more likely to be admitted to the ICU. Trauma type, mGCS, and ATT score were found to be associated with survival.

CONCLUSIONS

The present study highlights that dogs suffering from a combination of blunt and penetrating trauma are more likely to suffer moderate to severe injuries, have lower survival rates, and are more likely to be admitted to the ICU compared to dogs suffering from only blunt or penetrating trauma. Trauma type, mGCS, and ATT scores were found to be associated with survival in all groups.

At risk child: a contemporary analysis of injured children in London and the South East of England: a prospective, multicentre cohort study

Background

Injury is a leading health burden in children yet relatively little is reported about the contemporary risks they face. Current national registry data may under-represent the true burden of injury to children. We aim to analyse contemporary patterns of paediatric trauma and identify current factors putting children at risk of injury.

Methods

A 3-month prospective multicentre cohort evaluation of injured children across the London Major Trauma System was performed. All children receiving a trauma team activation; meeting National Institute for Health and Care Excellence CT head criteria; or admitted/transferred out due to trauma were included. Data were collected on demographics, mechanism and location of injury, and body region injured. The primary outcome was in-hospital mortality and secondary outcome was safeguarding concerns.

Results

659 children were included. Young children were more likely to be injured at home (0-5 years old: 70.8%, n=167 vs adolescents: 15.6%, n=31). Adolescents were more likely to be injured in the street (42.7%, n=85). Head trauma caused over half of injuries in 0-5 years old (51.9%, n=121). Falls were common and increasingly prevalent in younger children, causing 56.6% (n=372) of injuries. In adolescents, penetrating violence caused more than one in five injuries (21.9%, n=50). Most injured children survived (99.8%, n=658), however, one in four (26.1%, n=172) had safeguarding concerns and a quarter of adolescents had police, third sector or external agency involvement (23.2%, n=53).

Conclusions

This study describes modern-day paediatric trauma and highlights the variance in injury patterns in young children and adolescents. Importantly, it highlights differences in actual rates of injuries compared with those reported from current national registry data. We must understand real risks facing 21st century children to effectively safeguard future generations. The results provide an opportunity to reassess the current approach to injury prevention, child and adolescent safeguarding, and public health campaigns for child safety.

Comparison of the Pediatric Resuscitation and Trauma Outcome (PRESTO) Model and Pediatric Trauma Scoring Systems in a Middle-Income Country

BACKGROUND

The pediatric resuscitation and trauma outcome (PRESTO) model was developed to aid comparisons of risk-adjusted mortality after injury in low- and middle-income countries (LMICs). We sought to validate PRESTO using data from a middle-income country (MIC) trauma registry and compare its performance to the Pediatric Trauma Score (PTS), Revised Trauma Score, and pediatric age-adjusted shock index (SIPA).

METHODS

We included children (age < 15 years) admitted to a single trauma center in South Africa from December 2012 to January 2019. We excluded patients missing variables necessary for the PRESTO model-age, systolic blood pressure, pulse, oxygen saturation, neurologic status, and airway support. Trauma scores were assigned retrospectively. PRESTO's previously high-income country (HIC)-validated optimal threshold was compared to MIC-validated threshold using area under the receiver operating characteristic curves (AUROC). Prediction of in-hospital death using trauma scoring systems was compared using ROC analysis.

RESULTS

Of 1160 injured children, 988 (85%) had complete data for calculation of PRESTO. Median age was 7 (IQR: 4, 11), and 67% were male. Mortality was 2% (n = 23). Mean predicted mortality was 0.5% (range 0-25.7%, AUROC 0.93). Using the HIC-validated threshold, PRESTO had a sensitivity of 26.1% and a specificity of 99.7%. The MIC threshold showed a sensitivity of 82.6% and specificity of 89.4%. The MIC threshold yielded superior discrimination (AUROC 0.86 [CI 0.78, 0.94]) compared to the previously established HIC threshold (0.63 [CI 0.54, 0.72], p < 0.0001). PRESTO showed superior prediction of in-hospital death compared to PTS and SIPA (all p < 0.01).

CONCLUSION

PRESTO can be applied in MIC settings and discriminates between children at risk for in-hospital death following trauma. Further research should clarify optimal decision thresholds for quality improvement and benchmarking in LMIC settings.

Closing the gap in care of blunt solid organ injury in children

INTRODUCTION

Cross-sectional data of pediatric blunt solid organ injury demonstrates higher rates of nonoperative management and shorter lengths of stay (LOSs) in pediatric trauma centers (PTCs) versus adult trauma centers (ATCs) or dual trauma centers (DTCs). Recent iterations of guidelines (McVay 2008, J Pediatr Surg 2008;43(6):1072-1076 J Trauma Acute Care Surg 2015;79(4):683-693) have emphasized physiologic parameters rather than injury grade in clinical decision making, improving resource allocation and decreasing LOS. We sought to evaluate how these guidelines have influenced care.

METHODS

The National Trauma Data Bank (2007-2016) was queried for isolated spleen and liver injuries in patients younger than 19 years. Linear regression, odds ratio (OR), and χ test were used to determine significance between operative intervention or LOS among different trauma center types and grade of injury.

RESULT

A total of 55,036 blunt spleen or liver injuries were identified. Although operative rates decreased in ATCs over time (p = 0.037), patients treated at ATCs or DTCs continued to demonstrate higher ORs of operative intervention (OR, 4.43 and 2.88, respectively) compared with PTCs. Mean LOS decreased by 1.52 (p < 0.001), 0.49 (p = 0.26), and 1.31 (p = 0.05) days at ATC, DTC, and PTC to 6.43, 6.68, and 5.16 days. Improvement in LOS for ATCs was distributed across injury Grades I, II, and IV, while there was no correlation among PTCs for injury grade.

CONCLUSION

Despite more than a decade of guidelines in pediatric solid organ injury supporting nonoperative management and accelerated discharge pathways based on physiologic parameters, rates of operative intervention remain much higher in ATCs versus PTCs, and all centers appear to fall short of consensus guidelines for discharge.

Prevalence of nonaccidental trauma among children at American College of Surgeons-verified pediatric trauma centers

BACKGROUND

Child abuse remains a national epidemic that has detrimental effects if unnoticed in the clinical setting. Extreme cases of child abuse, or nonaccidental trauma (NAT), have large financial burdens associated with them due to treatment costs and long-term effects of abuse. Clinicians who have additional training and experience with pediatric trauma are better equipped to detect signs of NAT and have more experience reporting it. This additional training and experience can be measured by using the American College of Surgeons (ACS) Pediatric Trauma verification. It is hypothesized that ACS-verified pediatric trauma centers (vPTCs) have an increased prevalence of NAT because of this additional experience and training relative to non-ACS vPTCs.

METHODS

The National Trauma Data Bank, for the years 2007 to 2014, was utilized to compare the prevalence of NAT between ACS vPTCs relative to non-ACS vPTCs to produce both crude and Injury Severity Score adjusted prevalence ratio estimates.

RESULTS

The majority of NAT cases across all hospitals were male (58.3%). The mean age of the NAT cases was 2.3 years with a mean Injury Severity Score (ISS) of 11.1. The most common payment method was Medicaid (64.4%). The prevalence of NAT was 1.82 (1.74-1.90) times higher among ACS vPTCs and 1.81 (1.73-1.90) after adjusting for ISS.

CONCLUSIONS

The greater prevalence of NAT at vPTCs likely represents a more accurate measure of NAT among pediatric trauma patients, likely due to more experience and training of clinicians.
