A multicenter prospective analysis of pediatric trauma activation criteria routinely used in addition to the six criteria of the American College of Surgeons

BACKGROUND The American College of Surgeons has defined six minimum activation criteria (ACS-6) for the highest level of trauma activations at trauma centers. The verification criteria also allow for the inclusion of additional criteria at the institution’s discretion. The purpose of this prospective multicenter study was to evaluate the ACS-6 as well as commonly used activation criteria to evaluate overtriage and undertriage rates for pediatric trauma team activation. METHODS Data were prospectively collected at nine pediatric trauma centers to examine 29 commonly used activation criteria. Patients meeting any of these criteria were evaluated for the use of high-level trauma resuscitation resources according to an expert consensus list. Patients requiring a resource but not meeting any activation criteria were included to evaluate undertriage rates. RESULTS During the 1-year study, a total of 656 patients were enrolled with a mean age of 8 years, a median Injury Severity Score of 14, and mortality of 11%. Using all criteria, 55% of patients would have been overtriaged and 9% would have been undertriaged. If only the ACS-6 were used, 24% of patients would have been overtriaged and 16% would have been undertriaged. Among activation criteria with more than 10 patients, those most predictive of using a high-level resource were a gunshot wound to the abdomen (92%), blood given before arrival (83%), traumatic arrest (83%), tachycardia/poor perfusion (83%), and age-appropriate hypotension (77%). The addition of tachycardia/poor perfusion and pretrauma center resuscitation with greater than 40 mL/kg results in eight criteria with an overtriage of 39% and an undertriage of 10.5%. CONCLUSION The ACS-6 provides a reliable overtriage or undertriage rate for pediatric patients. The inclusion of two additional criteria can further improve these rates while maintianing a simplified triage list for children. LEVEL OF EVIDENCE Therapeutic study, level III.

Effect of an educational intervention on nursing staff knowledge, confidence, and practice in the care of children with mild traumatic brain injury.

Background: Nurses are key providers in the care of children with mild traumatic brain injury (mTBI). New treatment recommendations emphasize symptom assessment and brain rest guidelines to optimize recovery. This study compared pediatric trauma core nurses’ knowledge, degree of confidence, and perceived change in practice following mTBI education. Methods: Twenty-eight trauma core nurses were invited to participate in this voluntary quasiexperimental, one-group pretest–posttest study. Multiple choice questions were developed to assess knowledge, and self-report Likert scale statements were used to evaluate confidence and change in practice. Baseline data of 25 trauma core nurses were assessed and then reassessed 1 month postintervention. Results: Paired samples analysis showed significant improvement in knowledge (mean pretest: 33.6% vs. mean posttest score: 79.2%; 95% CI [35.6, 55.6]; t = 9.368; p < .001). All but two test questions yielded a significant increase in the number of participants with correct responses. Preintervention confidence was low (0–32% per question) and significantly increased postintervention (26%–84% per question). Despite increased administration of the symptom assessment and identification of interventions for symptom resolution posteducation (&khgr;2 = 6.125, p = .001), these scores remained low. Conclusion: Findings demonstrate that educational intervention effectively increased trauma core nurses’ knowledge and confidence in applying content into practice. Postintervention scores did not uniformly increase, and not all trauma core nurses consistently transferred content into practice. Further research is recommended to evaluate which teaching method and curriculum content are most effective to educate trauma core nurses and registered nurses caring for patients with mTBI and to identify barriers to incorporating this knowledge in practice.

Assessment of factors associated with the delayed transfer of pediatric trauma patients: an emergency physician survey.

Objectives The purpose of this study was to identify, among emergency department (ED) physicians, the potential barriers impacting the appropriate and timely transfer of injured children to pediatric trauma centers. Methods Surveys assessed pediatric trauma knowledge and experience, transfer and imaging decisions, and perceived barriers to patient transfer. Two scenarios were created; one with a child meeting the state trauma triage criteria and one who did not. In April 2010, 936 surveys were mailed to randomly selected ED physicians. Respondents could answer by mail or online until June 30, 2010. Results A total of 486 surveys were returned, and 109 were excluded, leaving 377 included in the study. A majority reported limited experience in the care of the critically ill child, with 93%, 99%, 99%, and 100% respectively, having performed less than 5 intubations, intraosseous line, central line, or chest tube placements in the last year. In the scenario in which the child met criteria to be transferred, 74% appropriately transferred the patient, whereas in the other scenario, 34% transferred the patient. As much as 56% of the respondents reported they would perform a head computed tomography before transfer, mainly to avoid missed injuries and medicolegal concerns. Among those who would not transfer either patient, 27% reported not having an on-call surgeon at all times. Conclusions Innovative measures should be developed so that ED physicians gain a greater understanding of the proper identification of pediatric patients requiring a timely transfer to a pediatric trauma center.

Proposed clinical pathway for nonoperative management of high-grade pediatric pancreatic injuries based on a multicenter analysis: A pediatric trauma society collaborative.

BACKGROUND Guidelines for nonoperative management (NOM) of high-grade pancreatic injuries in children have not been established, and wide practice variability exists. The purpose of this study was to evaluate common clinical strategies across multiple pediatric trauma centers to develop a consensus-based standard clinical pathway. METHODS A multicenter, retrospective review was conducted of children with high-grade (American Association of Surgeons for Trauma grade III-V) pancreatic injuries treated with NOM between 2010 and 2015. Data were collected on demographics, clinical management, and outcomes. RESULTS Eighty-six patients were treated at 20 pediatric trauma centers. Median age was 9 years (range, 1–18 years). The majority (73%) of injuries were American Association of Surgeons for Trauma grade III, 24% were grade IV, and 3% were grade V. Median time from injury to presentation was 12 hours and median ISS was 16 (range, 4–66). All patients had computed tomography scan and serum pancreatic enzyme levels at presentation, but serial enzyme level monitoring was variable. Pancreatic enzyme levels did not correlate with injury grade or pseudocyst development. Parenteral nutrition was used in 68% and jejunal feeds in 31%. 3Endoscopic retrograde cholangiopancreatogram was obtained in 25%. An organized peripancreatic fluid collection present for at least 7 days after injury was identified in 59% (42 of 71). Initial management of these included: observation 64%, percutaneous drain 24%, and endoscopic drainage 10% and needle aspiration 2%. Clear liquids were started at a median of 6 days (IQR, 3–13 days) and regular diet at a median of 8 days (IQR 4–20 days). Median hospitalization length was 13 days (IQR, 7–24 days). Injury grade did not account for prolonged time to initiating oral diet or hospital length; indicating that the variability in these outcomes was largely due to different surgeon preferences. CONCLUSION High-grade pancreatic injuries in children are rare and significant variability exists in NOM strategies, which may affect outcomes and effective resource utilization. A standard clinical pathway is proposed.

Consistent screening of admitted infants with head injuries reveals high rate of nonaccidental trauma

PURPOSE Implementation of a nonaccidental trauma (NAT) screening guideline for the evaluation of infants admitted with an unwitnessed head injury has eliminated screening disparities. This study sought to determine the overall NAT rate and key predictive factors using this guideline. METHODS All infants screened via the guideline from 2008 to 2015 were retrospectively reviewed. The overall rate of NAT as determined by our child abuse team was determined. In addition, a logistic regression model was developed to evaluate potential predictors of increased risk of NAT. RESULTS A total of 563 infants were screened with an overall rate of NAT of 25.6% (n=144). NAT screening was consistent across race and insurance status. By univariate analysis, patients with government insurance or no insurance had a significantly higher rate of NAT, but race was not a factor. Also NAT victims had significantly higher ISS. Skeletal survey showed high positive predictive value of 94%. When regression modeling was performed, ISS, abnormal skeletal survey and having public or no insurance were significantly correlated with NAT, while race showed no correlation. CONCLUSION One quarter of infants admitted with a head injury not witnessed in a public situation were identified as the victims of NAT. The high rate of abuse among this population supports routine screening in order to avoid missing intentional injuries and preventing future injuries. Race is not a predictor of NAT, but insurance status, as a proxy for socioeconomic status, is correlated, and further investigation is needed. LEVEL OF EVIDENCE III.

Routine surveillance imaging following mild traumatic brain injury with intracranial hemorrhage may not be necessary

BACKGROUND Mild traumatic brain injury (mTBI) comprises the majority of pediatric traumatic brain injury. Children with mTBI even with traumatic intracranial hemorrhage (tICH) rarely experience a clinically significant neurologic decline (CSND). The utility of routine surveillance imaging in the pediatric population also remains controversial, especially owing to concerns about the risks of radiation exposure at a young age. This study aims to identify demographic or injury-related characteristics that may facilitate recognition of children at risk of progression with mTBI. METHODS We performed a retrospective review of patients <16 years old with mTBI (GCS 13-15) and tICH admitted to a Level I pediatric trauma center between 2009 and 2014. Management of these patients was directed by the Cincinnati Childrens Hospital Medical Center Minor Head Injury Algorithm. We reviewed each chart with emphasis on patient demographics, injury specific data, and radiographic or clinical progression. RESULTS 154 patients met inclusion criteria with mean age of 4 [0-16]; 116 sustained an tICH and 38 patients had isolated skull fractures. Repeat neuroimaging was obtained in 68 patients (59%). Only 9 patients (13%) with tICH had radiographic progression, none of which resulted in CSND. In addition, 9 patients experienced CSND, leading to neurosurgical intervention in 6 patients. Notably, none of these patients had repeat imaging prior to their neurologic changes. Both CSND and need for intervention were significantly higher in patients with epidural hematomas than other types of tICH (19.2% vs. 1.1%, p = 0.002). Of 154 patients, 19 did not have documented follow-up, 135 were seen as outpatients and 65 (48%) had follow up neuroimaging. All patients who had surveillance imaging in the outpatient setting had stable or resolved tICH. CONCLUSION Few children with mTBI and tICH experience clinical decline. Importantly, all patients that required neurosurgical intervention were identified by clinical changes rather than via repeat imaging. Our study suggests that in the vast majority of cases, clinical monitoring alone is safe and sufficient in patients in order to avoid exposure to repeat radiographic imaging.

Pediatric trauma undertriage in Ohio

BACKGROUND Appropriate and timely triage is an essential component of a trauma system. In the state of Ohio there are 6 verified pediatric trauma centers (PTC) across 8 state regions. The purpose of this study was to better understand the pediatric under-triage rates in the state. METHODS We utilized the Ohio Trauma Registry from 2007 - 2012, consisting of 14,045 records of children < 16 years admitted to a hospital for greater than 48 hours or who sustained a traumatic death. Pediatric under-triage was defined as a combination of not being directly transported to a PTC when one was available within 30 minutes or not being transferred to a PTC within 2 hours of injury. RESULTS The state pediatric under-triage rate was 52%, only decreasing to 35% when up to a four-hour transfer time was allowed. Across state trauma regions, under-triage rates varied from 94% to 40%. Over 28% of injured children had access to a PTC within 30 minutes of their home. A trauma center (adult or pediatric) was within 30 minutes for 66% of the children, yet 32% of the children went to a non-trauma center (NTC) first. Overall, 29% of children never made it to a PTC and 4% of children remained at a NTC, with regional variation between from 5% to 0.5%. Statewide mortality was nearly 3% with regional variations between 5% to 0.4%. Mortality within the appropriately triaged group was 5.3% while only 0.7% in the under-triage group. Overall 53% of transferred patients had a greater than 2 hour transfer time. CONCLUSIONS In conclusion, despite the significant number of PTCs in Ohio, there remains a high under-triage rate with significant regional variations and long transfer times. Continued analysis will be useful in furthering trauma system development for the injured child.
