The paediatric polytrauma CT-indication (PePCI)-score-Development of a prognostic model to reduce unnecessary CT scans in paediatric trauma patients. Injury 2024; 55:111494. [PMID: 38521635 DOI: 10.1016/j.injury.2024.111494] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Revised: 02/03/2024] [Accepted: 03/07/2024] [Indexed: 03/25/2024]
Abstract
BACKGROUND Whole-Body CT (WBCT) is frequently used in emergency situations for promptly diagnosing paediatric polytrauma patients, given the challenges associated with obtaining precise details about the mechanism and progression of trauma. However, WBCT does not lead to reduced mortality in paediatric patients, but is associated with high radiation exposure. We therefore wanted to develop a screening tool for CT demand-driven emergency room (ER)-trauma diagnostic to reduce radiation exposure in paediatric patients. METHODS A retrospective study in a Level I trauma centre in Germany was performed. Data from 344 paediatric emergency patients with critical mechanism of injury who were pre-announced by the ambulance for the trauma room were collected. Patients' symptoms, clinical examination, extended Focused Assessment with Sonography for Trauma (eFAST), routinely, laboratory tests and blood gas and - when obtained - WBCT images were analysed. To identify potential predictors of severe injuries (ISS > 23), 300 of the 344 cases with complete data were subjected to regression analyses model. RESULTS Multiple regression analysis identified cGCS, base excess (BE), medically abnormal results from eFAST screening, initial unconsciousness, and injuries involving three or more body regions as significant predictors for a screening tool for decision-making to perform WBCT or selective CT. The developed Paediatric polytrauma CT-Indication (PePCI)-Score was divided into three risk categories and achieved a sensitivity of 87 % and a specificity of 71 % when comparing the low and medium risk groups with the high risk group. Comparing only the low-risk group with the high-risk group for the decision to perform WBCT, 32/35 (91 %) of patients with an ISS >23 were correctly identified, as were 124/137 (91 %) with lower ISS scores. CONCLUSION With the newly developed PePCI-Score, the frequency of WBCT in a paediatric emergency patients collective can be significantly reduced according to our data. After prospective validation, the initial assessment of paediatric trauma patients in the future could be made not only by the mechanism of injury, but also by the new PePCI-Score, deriving on clinical findings after thorough clinical assessment and the discretion of the trauma team.

Validation of the Conventional Trauma and Injury Severity Score and a Newly Developed Survival Predictive Model in Pediatric Patients with Blunt Trauma: A Nationwide Observation Study. CHILDREN (BASEL, SWITZERLAND) 2023; 10:1542.

Abstract
To date, there is no clinically useful prediction model that is suitable for Japanese pediatric trauma patients. Herein, this study aimed to developed a model for predicting the survival of Japanese pediatric patients with blunt trauma and compare its validity with that of the conventional TRISS model. Patients registered in the Japan Trauma Data Bank were grouped into a derivation cohort (2009-2013) and validation cohort (2014-2018). Logistic regression analysis was performed using the derivation dataset to establish prediction models using age, injury severity, and physiology. The validity of the modified model was evaluated by the area under the receiver operating characteristic curve (AUC). Among 11 predictor models, Model 1 and Model 11 had the best performance (AUC = 0.980). The AUC of all models was lower in patients with survival probability Ps < 0.5 than in patients with Ps ≥ 0.5. The AUC of all models was lower in neonates/infants than in other age categories. Model 11 also had the best performance (AUC = 0.762 and 0.909, respectively) in patients with Ps < 0.5 and neonates/infants. The predictive ability of the newly modified models was not superior to that of the current TRISS model. Our results may be useful to develop a highly accurate prediction model based on the new predictive variables and cutoff values associated with the survival mortality of injured Japanese pediatric patients who are younger and more severely injured by using a nationwide dataset with fewer missing data and added valuables, which can be used to evaluate the age-related physiological and anatomical severity of injured patients.

Abstract
INTRODUCTION in Brazil, trauma is responsible for 40% of deaths in the age group between 5 and 9 years old, and 18% between 1 and 4 years, and bleeding is the leading cause of preventable death in the traumatized child. Conservative management of blunt abdominal trauma with solid organs injury - started in the 60s - is the current world trend, with studies showing survival rates above 90%. The objective was to assess the efficacy and safety of conservative treatment in children with blunt abdominal trauma treated at the Clinical Hospital of the University of Campinas, in the last five years. METHODS retrospective analysis of medical records of patients classified by levels of injury severity, in 27 children. RESULTS only one child underwent surgery for initial failure of conservative treatment (persistent hemodynamic instability), resulting in a 96% overall success rate of the conservative treatment. Five other children (22%) developed late complications that required elective surgery: a bladder injury, two cases of infected perirenal collections (secondary to injury of renal collecting system), a pancreatic pseudocyst and a splenic cyst. Resolution of the complications was attained in all children, with anatomical and functional preservation of the affected organ. There were no deaths in this series. CONCLUSION the conservative initial approach in the treatment of blunt abdominal trauma was effective and safe with high resolution and low rate of complications leading to a high preservation rate of the affected organs. Level of evidence III - prognostic and therapeutic study.

Abstract
Objective To explore the optimal set of trauma activation criteria predicting paediatric patients' need for acute care following multi-trauma, with particular attention to Glasgow Coma Scale (GCS) cut-off value. Methods A retrospective cohort study of paediatric multi-trauma patients aged 0 to 16 years, performed at a Level 1 paediatric trauma centre. Trauma activation criteria and GCS levels were examined with respect to patients' need for acute care, defined as: direct to operating room disposition, intensive care unit admission, need for acute interventions in the trauma room, or in-hospital death. Results We enrolled 436 patients (median age 8.0 years). The following predicted need for acute care: GCS <14 (adjusted odds ratio [aOR] 23.0, 95% confidence interval [CI]: 11.5 to 45.9, P < 0.001), hemodynamic instability: (aOR 3.7, 95% CI: 1.2-8.1, P = 0.01), open pneumothorax/flail chest (aOR: 20.0, 95% CI: 4.0 to 98.7, P < 0.001), spinal cord injury (aOR 15.4, 95% CI; 2.4 to 97.1, P = 0.003), blood transfusion at the referring hospital (aOR: 7.7, 95% CI: 1.3 to 44.2, P = 0.02) and GSW to the chest, abdomen, neck, or proximal extremities (aOR 11.0, 95% CI; 1.7 to 70.8, P = 0.01). Using these activation criteria would have decreased over- triage by 10.7%, from 49.1% to 37.2% and under-triage by 1.3%, from 4.7% to 3.5%, in our cohort of patients. Conclusions Using GCS<14, hemodynamic instability, open pneumothorax/flail chest, spinal cord injury, blood transfusion at the referring hospital, and GSW to the chest, abdomen, neck of proximal extremities, as T1 activation criteria could decrease over- and under-triage rates. Prospective studies are needed to validate the optimal set of activation criteria in paediatric patients.

Abstract
RESUMO Introdução: no Brasil, o trauma é responsável por 40% dos óbitos na faixa etária entre 5 e 9 anos, e 18% entre 1 e 4 anos, e o sangramento é a principal causa de prevenção morte na criança traumatizada. O manejo conservador de trauma abdominal contuso com lesão de órgãos sólidos - iniciado na década de 60 - é a tendência mundial atual, com estudos mostrando taxas de sobrevivência acima de 90%. O objetivo do presente trabalho foi avaliar a eficácia e segurança do tratamento conservador em crianças com trauma abdominal contuso tratado no Hospital das Clínicas da Universidade de Campinas, nos últimos cinco anos. Métodos: análise retrospectiva de prontuários de pacientes classificados por níveis de gravidade da lesão, em 27 crianças. Resultados: apenas uma criança foi submetida a cirurgia por falha inicial do tratamento conservador (instabilidade hemodinâmica persistente), resultando em uma taxa de sucesso global de 96% do tratamento conservador inicial. Outras cinco crianças (22%) desenvolveram complicações tardias que exigiram cirurgias eletivas: lesão na bexiga, dois casos de coleção perirenal infectada (secundária à lesão de sistema de coleta renal), um pseudocisto pancreático e um cisto esplênico. Resolução da complicação foi atingida em todas as crianças, com preservação anatômica e funcional do órgão afetado. Não houve mortes nesta série. Conclusão: a abordagem inicial conservadora no tratamento de trauma abdominal contundente foi eficaz e segura com alta resolução e baixa taxa de complicações levando a uma alta taxa de preservação dos órgãos afetados. Nível de evidência III - estudo prognóstico e terapêutico.

Abstract
Introduction The influence of reduced functional status has become increasingly relevant because of the gradual decline in mortality rate over the recent years. Nonetheless, only a few studies investigating the functional status of patients with trauma at hospital discharge have been conducted. This study aimed to identify the risk factors influencing the mortality rate in pediatric trauma survivors at a pediatric intensive care unit and analyze their functional status using the Functional Status Scale (FSS). Methods A retrospective analysis was conducted at Shengjing Hospital of China Medical University. Children admitted to the pediatric intensive care unit between January 2015 and January 2020 who met the trauma diagnostic criteria were included. The FSS score and the Injury Severity Score (ISS) were recorded upon admission and discharge, respectively. Clinical data were compared between the survival and non-survival groups to identify the risk factors for poor prognosis. The risk factors for mortality were identified using multivariate and univariate analyses. Results A total of 246 children {59.8%, male; median [interquartile range (IQR)] age: 3 [1-7] years} were diagnosed with trauma (including head trauma, chest trauma, abdominal trauma, and extremity trauma). Of these patients, 207 were discharged, 11 dropped out mid-treatment, and 39 died (hospital mortality rate, 15.9%). Upon admission, the median FSS and trauma scores were 14 (IQR, 11-18) and 22 (IQR, 14-33) points, respectively. At discharge, the FSS score was 8 (IQR, 6-10) points. The patient clinical status improved with a ΔFSS score of -4 (IQR, -7, 0) points. At hospital discharge, 119 (48.3%), 47 (19.1%), 27 (11.0%), 12 (4.8%), and 2 (0.9%) survivors had good, mildly abnormal, moderately abnormal, severely abnormal, and very severely abnormal function, respectively. Reduced functional status in patients was categorized as follows: motor, 46.4%; feeding, 26.1%; sensory, 23.2%; mental, 18.4%; and communication, 17.9%. In the univariate analysis, ISS >25 points, shock, respiratory failure, and coma were independently associated with the mortality rate. Multivariate analysis revealed that the ISS was an independent risk factor for mortality. Conclusion The mortality rate of patients with trauma was high. ISS was an independent risk factor for mortality. Mildly reduced functional status remained at discharge and was reported in nearly half of the discharged patients. Motor and feeding functions were the most severely impacted domains.

Abstract
BACKGROUND There are limited data on the association between transport distance and outcomes in pediatric patients with severe traumatic brain injuries (sTBIs), despite children having to travel further to pediatric trauma centers (PTCs). OBJECTIVE To assess whether distance from a PTC is associated with outcomes in children who undergo cranial surgery after sTBI. METHODS Children with sTBI who underwent craniectomy/craniotomy at our PTC between 2010 and 2019 were identified retrospectively. Of these 92 patients, 83 sustained blunt injury and underwent surgery within 24 hours. The distance from injury location to PTC was based on injury zip code and calculated as Euclidean distance. Variables associated with transport, including distance, time, and rural-urban disparity, were analyzed for correlation with poor outcome. RESULTS Of the 83 patients identified, 81 had injury location information. Forty patients were injured within 30 miles and 41 were injured ≥30 miles from the PTC. Injury severity and pediatric trauma scores were not significantly different between groups. Sixty-eight children (82%) had a satisfactory outcome and 10 children (12%) died. There was a nonsignificant association between distance traveled and poor outcome, even when the cohort was stratified into those with subdural hematomas and those with nonabusive injuries. CONCLUSIONS Regardless of the distance from the PTC at which their injury occurred, most children in this cohort made a moderate to good recovery. Children injured at greater distances from the PTC did not have worse outcomes; however, studies with larger cohorts are needed to more definitively assess prehospital pediatric transport systems in this population.

[PMID: 36010111 PMCID: PMC9406594 DOI: 10.3390/children9081222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/02/2022] [Revised: 07/27/2022] [Accepted: 08/09/2022] [Indexed: 11/16/2022]
Abstract
Background: Many hospitals have adopted screening tools to assess risk for posttraumatic stress disorder (PTSD) after pediatric unintentional injury in accordance with American College of Surgeons recommendations. The Screening Tool for Early Predictors of PTSD (STEPP) is a measure initially developed to identify youth and parents at high risk for meeting diagnostic criteria for PTSD after injury. Acute pain during hospitalization has also been examined as a potential predictor of maladaptive outcomes after injury, including PTSD. We investigated in a retrospective cohort study whether the STEPP, as well as acute pain intensity during hospitalization, would predict maladaptive outcomes during the peri-trauma in addition to the post-trauma period, specifically length of hospitalization. Methods: A total of 1123 youths aged 8–17 (61% male) and their parents were included. Patients and parents were administered the STEPP for clinical reasons while hospitalized. Acute pain intensity and length of stay were collected through retrospective chart review. Results: Adjusting for demographics and injury severity, child but not parent STEPP total predicted length of stay. Acute pain intensity, child threat to life appraisal, and child pulse rate predicted length of stay. Conclusions: Acute pain intensity and child PTSD risk factors, most notably child threat to life appraisal, predicted hospitalization length above and beyond multiple factors, including injury severity. Pain intensity and child appraisals may not only serve as early warning signs for maladaptive outcomes after injury but also indicate a more difficult trajectory during hospitalization. Additional assessment and treatment of these factors may be critical while youth are hospitalized. Utilizing psychology services to support youth and integrating trauma-informed care practices during hospitalization may support improved outcomes for youth experiencing unintentional injury.
