Reverse shock index multiplied by the motor component of the Glasgow Coma Scale predicts mortality and need for intervention in pediatric trauma patients

BACKGROUND

Timely identification of high-risk pediatric trauma patients and appropriate resource mobilization may lead to improved outcomes. We hypothesized that reverse shock index times the motor component of the Glasgow Coma Scale (rSIM) would perform equivalently to reverse shock index times the total Glasgow Coma Scale (rSIG) in the prediction of mortality and the need for intervention following pediatric trauma.

METHODS

The 2017-2020 National Trauma Data Bank datasets were used. We included all patients <16 years of age that had a documented prehospital and trauma bay systolic blood pressure, heart rate, and total GCS. We excluded all patients who arrived at the trauma center without vital signs and interfacility transport patients. Receiver operating characteristic (ROC) curves were used to model the performance of each metric as a classifier with respect to our primary and secondary outcomes, and the area under the ROC curve (AUC) was used for comparison. Our primary outcome was mortality prior to hospital discharge. Secondary outcomes included blood product administration or hemorrhage control intervention (surgery or angiography) < 4 hours following hospital arrival and ICU admission.

RESULTS

After application of exclusion criteria, 77,996 patients were included in our analysis. rSIM and rSIG performed equivalently as predictors of mortality in the 1-2 (p = 0.05) and 3-5 (p = 0.28) year categories, but rSIM was statistically outperformed by rSIG in the 6-12 (AUC: 0.96 vs. 0.95, p = 0.04) and 13-16 (AUC: 0.96 vs. 0.95, p < 0.01) year-old age categories. rSIM and rSIG also performed similarly with respect to prediction of secondary outcomes.

CONCLUSION

rSIG and rSIM are both outstanding predictors of mortality following pediatric trauma. Statistically significant differences in favor of rSIG were noted in some age groups. Because of the simplicity of calculation, rSIM may be a useful tool for pediatric trauma triage.

En Bloc Resection of a Giant Ganglioneuroma of the Chest Through Clamshell Thoracotomy

Ganglioneuroma is a benign tumor requiring subtotal resection as a primary mode of treatment. There are several surgical approaches. A giant ganglioneuroma of the chest cavity may be approached via a clamshell thoracotomy. This manuscript presents a case of giant ganglioneuroma resected en bloc via clamshell thoracotomy in a seven-year-old child.

Provider education decreases opioid prescribing after pediatric umbilical hernia repair

PURPOSE

To improve opioid stewardship for umbilical hernia repair in children.

METHODS

An educational intervention was conducted at 9 centers with 79 surgeons. The intervention highlighted the importance of opioid stewardship, demonstrated practice variation, provided prescribing guidelines, encouraged non-opioid analgesics, and encouraged limiting doses/strength if opioids were prescribed. Three to six months of pre-intervention and 3 months of post-intervention prescribing practices for umbilical hernia repair were compared.

RESULTS

A total of 343 patients were identified in the pre-intervention cohort and 346 in the post-intervention cohort. The percent of patients receiving opioids at discharge decreased from 75.8% pre-intervention to 44.6% (p < 0.001) post-intervention. After adjusting for age, sex, umbilicoplasty, and hospital site, the odds ratio for opioid prescribing in the post- versus the pre-intervention period was 0.27 (95% CI = 0.18-0.39, p < 0.001). Among patients receiving opioids, the number of doses prescribed decreased after the intervention (adjusted mean 14.3 to 10.4, p < 0.001). However, the morphine equivalents/kg/dose did not significantly decrease (adjusted mean 0.14 to 0.13, p = 0.20). There were no differences in returns to emergency departments or hospital readmissions between the pre- and post-intervention cohorts.

CONCLUSIONS

Opioid stewardship can be improved after pediatric umbilical hernia repair using a low-fidelity educational intervention.

Supplements, nutrition, and alternative therapies for the treatment of traumatic brain injury

Studies using traditional treatment strategies for mild traumatic brain injury (TBI) have produced limited clinical success. Interest in treatment for mild TBI is at an all time high due to its association with the development of chronic traumatic encephalopathy and other neurodegenerative diseases, yet therapeutic options remain limited. Traditional pharmaceutical interventions have failed to transition to the clinic for the treatment of mild TBI. As such, many pre-clinical studies are now implementing non-pharmaceutical therapies for TBI. These studies have demonstrated promise, particularly those that modulate secondary injury cascades activated after injury. Because no TBI therapy has been discovered for mild injury, researchers now look to pharmaceutical supplementation in an attempt to foster success in human clinical trials. Non-traditional therapies, such as acupuncture and even music therapy are being considered to combat the neuropsychiatric symptoms of TBI. In this review, we highlight alternative approaches that have been studied in clinical and pre-clinical studies of TBI, and other related forms of neural injury. The purpose of this review is to stimulate further investigation into novel and innovative approaches that can be used to treat the mechanisms and symptoms of mild TBI.

Pediatric Secondary Overtriage in a Statewide Trauma System

Secondary overtriage is a term that describes patients who are discharged home shortly after being transferred, an indication that transfer and hospitalization were unnecessary. The study goal was to identify factors associated with secondary triage. A statewide trauma registry was used to identify trauma patients aged less than 18 years during a 6-year period (2007-2012) who were discharged within 48 hours from arrival and did not undergo a surgical procedure. We compared those that were treated at initial facility and those transferred to a second facility using clinical indices including patterns of injury pattern using multivariate logistic regression. Of the 4441 patients who fit our inclusion criteria, 801 (18%) were transferred. Younger age groups were more likely to be transferred. Factors associated with being transferred included head, spinal, and facial injuries, and patient arrival during the nighttime work shifts. In conclusion, young patients who have signs of possible neurological or spinal injuries and those who arrive during nondaytime shifts during the workday are more likely to be transferred to another trauma center. These may reflect the comfort level and resources of the local facility.

Delineation of Criteria for Admission to Step down in the Mild Traumatic Brain Injury Patient

Patients that suffer a mild traumatic brain injury (TBI) with intracranial hemorrhage are commonly admitted to an intensive care unit with repeat imaging in 12 to 24 hours. This is costly to the health-care system. This study aimed to evaluate this practice and to identify criteria to triage patients to lower levels of monitored care. A retrospective review was performed at a university-based Level I trauma center. Patients with mild TBI were included. Data were collected on demographics, neurological status at 6, 12, and 24 hours, CT scan results, and medical or surgical interventions were required. A total of 389 patients were evaluated, 53 had a documented neurological decline while being admitted. Factors found to be associated with a neurological decline included Glasgow Coma Scale (GCS) < 15 ( P = 0.002), age greater than 55 ( P < 0.001), and warfarin use ( P = 0.039). Aspirin and Plavix were not associated with neurological decline. No patient age <55 with a GCS of 15 had a documented decline. Several risk factors were found to be associated with neurological decline after mild TBI. These include age, GCS < 15, and warfarin use. Patients aged <55 with GCS 15, posed minimal risk for deterioration. Patients aged <55 and with a GCS of 15 can be admitted to a monitored step-down bed with less frequent neurological checks.

Investigating the Impact of Preparation Strategies on USMLE Step 1 Performance

BACKGROUND

The USMLE Step 1 score helps differentiate applicants for competitive residency programs. Students frequently ask medical educators how to prepare for this high-stakes exam. Multiple resources exist such as books, training programs, and question banks. The purpose of this study is to provide medical educators with data on which resources correlate with higher exam scores.

METHODS

164 medical students at West Virginia University School of Medicine were given a survey following the completion of Step 1. The survey contained questions about resources used and exam date. De-identified data was paired with class quartile rankings and Step 1 scores. Average Step 1 scores were calculated for each resource and a student's t-test was used to compare between groups. Test dates were also broken into quintiles and average Step 1 scores were compared between groups.

RESULTS

Students who used the USMLE World question bank had higher Step 1 scores (M=229, SE=1.4) compared to students who did not use this resource (M=215, SE=4.2). Commercial preparation courses were not associated with improved scores. The timing of when the exam was taken was also not associated with significant differences between scores.

CONCLUSIONS

Interactive study options offer the best choice to improve USMLE Step 1 scores.

Osteonecrosis of Interphalangeal Joint of Thumb Two Months after Rattlesnake Bite

This case report details the osteonecrosis of the interphalangeal (IP) joint of the thumb two months after a rattlesnake bite. It describes the clinical presentation, imaging studies, histological review, pathology review, and review of literature. Our patient was a fifty-one year-old male who obtained a poisonous snakebite to the thumb. While in the hospital for acute treatment, a blood blister was debrided. He was seen two weeks after discharge for further debridement of epidermolysis. Patient presented one month later with a hand x-ray demonstrating bony erosions, and a bone scan showing active changes in the IP joint of his right thumb. He was taken to the OR for further debridement and definitive diagnosis. Pathology results confirmed osteonecrosis with negative bone cultures. The clinical presentation, diagnosis, and operative management of osteonecrosis offer a unique challenge, especially in a patient presenting with osteonecrosis from a poisonous snakebite.
