Initial CT Imaging Predicts Mortality in Severe Traumatic Brain Injuries in Pediatric Population-A Systematic Review and Meta-Analysis

The purpose of this systematic review was to analyze evidence based on existing studies on the ability of initial CT imaging to predict mortality in severe traumatic brain injuries (TBIs) in pediatric patients. An experienced librarian searched for all existing studies based on the inclusion and exclusion criteria. The studies were screened by two blinded reviewers. Of the 3277 studies included in the search, data on prevalence of imaging findings and mortality rate could only be extracted from 22 studies. A few of those studies had patient-specific data relating specific imaging findings to outcome, allowing the data analysis, calculation of the area under the curve (AUC) and receiver operating characteristic (ROC), and generation of a forest plot for each finding. The data were extracted to calculate the sensitivity (SN), specificity (SP), positive predictive value (PPV), negative predicted value (NPV), AUC, and ROC for extradural hematoma (EDH), subdural hematoma (SDH), traumatic subarachnoid hemorrhage (tSAH), skull fractures, and edema. There were a total of 2219 patients, 747 females and 1461 males. Of the total, 564 patients died and 1651 survived; 293 patients had SDH, 76 had EDH, 347 had tSAH, 244 had skull fractures, and 416 had edema. The studies included had high bias and lower grade of evidence. Out of the different CT scan findings, brain edema had the highest SN, PPV, NPV, and AUC. EDH had the highest SP to predict in-hospital mortality.

Provider perceptions of severe pediatric traumatic brain injury care priorities across hospitals in South America before and during the COVID-19 pandemic

Background

To understand provider perceptions of the COVID-19 pandemic on priorities of severe pediatric traumatic brain injury (TBI) care across hospitals in South America.

Methods

Site principal investigators (PIs) from 17 hospitals in South America enrolled in the PEGASUS-Argentina randomized controlled trial completed questionnaires regarding order of tasks performed in the care of a typical pediatric patient with severe TBI before (2019) and during (2021) the COVID-19 pandemic. Acute care processes were examined by quintiles to identify early, mid, and late actions and were categorized and compared. Associations of hospital volume and subspecialty resource availability with prioritization of key process actions were examined.

Finding

Site PIs from 15 and 16 hospitals completed the surveys in 2019 and 2021, respectively, including 14 who completed both. Action category order was stable between 2019 and 2021 and were ranked in priorities as: initial encounter, primary survey, interventions and invasive monitors, diagnostics, medications, staff communication, then disposition (in 2019) or nutrition (in 2021). There was variation in specific action order between hospitals at both timepoints, with only a few initial encounter and disposition actions limited to a single quintile. There was no reported association between hospital volume or subspecialty resource availability with prioritization of key process actions.

Interpretation

Despite novel healthcare challenges presented by the COVID-19 pandemic, providers in South America perceived maintaining standard severe pediatric TBI care consistent with BTF guidelines. There was large variability in specific action order between individual hospitals reported.

Effect of Hypothermia Therapy on Children with Traumatic Brain Injury: A Meta-Analysis of Randomized Controlled Trials

Hypothermia therapy is a promising therapeutic strategy for traumatic brain injury (TBI); however, some trials have shown that hypothermia therapy has a negative effect on patients with TBI. The treatment of hypothermia in children with TBI remains controversial. We conducted a search of six online databases to validate the literature on comparing hypothermia with normal therapy for children with TBI. Eight randomized controlled trials (514 patients) were included. The meta-analysis indicated that hypothermia therapy may increase the Glasgow Outcome Scale (GOS) scores. However, in terms of improving the rate of complications, intracranial pressure (ICP), mortality, cerebral perfusion pressure (CPP), and length of stay both in hospital as well as pediatric ICU, the difference was not statistically significant. Hypothermia therapy may have clinical advantages in improving the GOS scores in children with TBI compared with normothermic therapy, but hypothermia therapy may have no benefit in improving the incidence of complications, ICP, mortality, CPP, and length of stay both in pediatric ICU as well as hospital. The decision to implement hypothermia therapy for children with TBI depends on the advantages and disadvantages from many aspects and these must be considered comprehensively.

The Status of Quality Improvement Programs for Pediatric Traumatic Brain Injury Care in Argentina

INTRODUCTION

Trauma quality improvement (QI) programs improve care and outcomes for injured patients. Information about QI programs for pediatric traumatic brain injury (TBI) is sparse in Latin America.

METHODS

We gathered data on the status of QI programs and activities that encompass pediatric TBI at 15 Argentine hospitals. Data were gathered during 2019 and included hospital characteristics, QI practices, presence of a queryable registry, and use of protocols for TBI care. Level of QI activities was compared between hospital types using Fisher's exact test.

RESULTS

Most hospitals had guidelines for pediatric TBI care, including management and/or prevention of intracranial pressure (100%) and central-line-associated infections (87%). Morbidity and mortality meetings or other types of case discussions in which quality of pediatric TBI care was discussed were held by all hospitals, with most (53%) having weekly-monthly meetings, but 27% having rare or annual meetings. Sixty percent of hospitals had adequate data for case reviews (fewer than 25% of cases with essential information missing). Fifty-three percent documented discussions that occurred at these meetings and 53% utilized computerized trauma registries. Larger hospitals (> 200 beds) more frequently had adequate data (88%) for case reviews than smaller hospitals (29%, P = 0.046). Hospital size did not affect other QI activities.

CONCLUSIONS

Most hospitals had guidelines for pediatric TBI care. Adequacy of care was discussed at reasonably frequent case conferences. Opportunities for improvement include increasing documentation of case reviews and improving adequacy of data for case reviews, especially at smaller hospitals. Greater use of computerized trauma registries could provide such data.

Survey of resources available to implement severe pediatric traumatic brain injury management guidelines in low and middle-income countries

PURPOSE

Traumatic brain injury (TBI) is a leading cause of death and disability worldwide, with a disproportionately high burden in low-middle income countries. Guideline implementation has been associated with mortality reduction in high-income countries (HIC), but it is not known if hospitals in low and middle-income countries possess the resources to implement the pre-hospital TBI guidelines and the guidelines for the management of severe pediatric traumatic brain injury.

METHOD

An anonymous online survey was undertaken by a range of health care professionals currently managing children with severe TBI in low to middle-income countries. A variety of international and national pediatric, intensive care, and neurological societies assisted in the survey distribution. Thirty-eight questions were included to evaluate patient care and the provider's perceptions of their resources available to implement the pre-hospital specific TBI and current pediatric severe TBI guidelines.

RESULTS

Two hundred and forty-seven hospitals were represented from 68 countries. Fifty percent of LMIC hospitals that responded had the resources to implement 13 of 15 guidelines for the pediatric component of pre-hospital management for TBI and all baseline care recommendations. First tier therapies including the intracranial pressure (ICP) and cerebral perfusion pathways (CPP), however, demonstrated low capacity for uptake with 21.5% and 38.5% of surveyed hospitals possessing sufficient resources to follow the recommended pathways.

CONCLUSION

Pediatric TBI ICP/CPP management guidelines require numerous resources not widely sourced in LMIC. The creation of international guidelines that outline recommendations of care for LMIC may benefit patient care and outcomes in these settings.

Ability of the PILOT score to predict 6-month functional outcome in pediatric patients with moderate-severe traumatic brain injury

PURPOSE

To assess the Pediatric Intensity Level of Therapy (PILOT) score alone and in combination with Emergency Department (ED) GCS and Rotterdam score of initial head CT to predict functional outcomes in children with traumatic brain injury (TBI).

METHODS

Children (n=108) aged 31months-15years with moderate to severe TBI were prospectively enrolled at two sites. The ability of PILOT, ED GCS, and Rotterdam scores to predict the 6-month Pediatric Injury Functional Outcome Scale (PIFOS) was evaluated using multivariable regression models with enrollment site, age, and sex as covariates.

RESULTS

PILOT total (sum) score was more predictive of PIFOS (R²=0.23) compared to mean (R² = 0.20) or peak daily PILOT scores (R²=0.11). PILOT total score predicted PIFOS better than ED GCS (R²=0.01) or Rotterdam score (R²=0.06) and was similar to PILOT, ED GCS, and Rotterdam score combined. PILOT total score performed better in patients with intracranial pressure monitors (n=30, R²=0.28, slope=0.30) than without (n=78, R²=0.09, slope=0.36).

CONCLUSIONS

The PILOT score correlated moderately with functional outcome following TBI and outperformed other common predictors. PILOT may be a useful predictor or moderator of functional outcomes.

Pattern and Outcome of Pediatric Traumatic Brain Injury at Hawassa University Comprehensive Specialized Hospital, Southern Ethiopia: Observational Cross-Sectional Study

BACKGROUND

Traumatic brain injury (TBI) is the most common cause of death/disability in children. The Glasgow coma scale and other parameters are used for treatment/follow-up of TBI. Childhood TBI data are scarce from sub-Saharan Africa. The study aimed to determine the pattern and predictors of the TBI outcome in Southern Ethiopia.

METHODS

An observational cross-sectional study was conducted from September 2017 to September 2018 at Hawassa University Hospital. Structured questionnaires were used for data collection. Significant associations were declared at a P value of <0.05.

RESULTS

There were 4,258 emergency room (ER) visits during the study period, and TBI contributed to 317 (7.4%) cases. The mean age of study subjects was 7.66 ± 3.88 years. Boys, predominantly above 5 years of age, comprise 218 (68.8%) of the study subjects with a male to female ratio of 2.2 : 1. Pedestrian road traffic accidents (RTA), 120 (37.9%), and falls, 104 (32.8%), were the commonest causes of TBI. Mild, moderate, and severe TBI were documented in 231 (72.9%), 61 (19.2%), and 25 (7.9%) of cases, respectively. Most of the TBI cases presented within 24 hrs of injury, 258 (81.4%). Recovery with no neurologic deficit, 267 (84.2%); focal neurologic deficit, 30 (9.5%); depressed mentation, 10 (3.2%); and death, 10 (3.2%), were documented. Signs of increased intracranial pressure (ICP) at admission [AOR: 1.415 (95% CI: 1.4058-9.557)], severe TBI [AOR: 2.553 (95% CI: 1.965-4.524)], presence of hyperglycemia [AOR: 2.318 (95% CI: 1.873-7.874)], and presence of contusion, diffuse axonal injury (DAI), or intracranial bleeding on the head computed tomography (CT) scan [AOR: 2.45 (95% CI: 1.811-7.952)] predicted poor TBI outcome.

CONCLUSION

TBI contributed to 7.4% of pediatric ER visits. Pedestrian RTA and falls, early presentation (<24 hours of injury), and mild form of TBI among boys were the most common documented patterns. ICP, hyperglycemia, severe TBI, and presence of contusion, DAI, or intracranial bleeding on head CT predicted poor outcome. Strategies to ensure road safety and to prevent falls and animal-related injuries and TBI follow-up for ICP and glycemic controls are recommended.

Enduring Neuroprotective Effect of Subacute Neural Stem Cell Transplantation After Penetrating TBI

Traumatic brain injury (TBI) is the largest cause of death and disability of persons under 45 years old, worldwide. Independent of the distribution, outcomes such as disability are associated with huge societal costs. The heterogeneity of TBI and its complicated biological response have helped clarify the limitations of current pharmacological approaches to TBI management. Five decades of effort have made some strides in reducing TBI mortality but little progress has been made to mitigate TBI-induced disability. Lessons learned from the failure of numerous randomized clinical trials and the inability to scale up results from single center clinical trials with neuroprotective agents led to the formation of organizations such as the Neurological Emergencies Treatment Trials (NETT) Network, and international collaborative comparative effectiveness research (CER) to re-orient TBI clinical research. With initiatives such as TRACK-TBI, generating rich and comprehensive human datasets with demographic, clinical, genomic, proteomic, imaging, and detailed outcome data across multiple time points has become the focus of the field in the United States (US). In addition, government institutions such as the US Department of Defense are investing in groups such as Operation Brain Trauma Therapy (OBTT), a multicenter, pre-clinical drug-screening consortium to address the barriers in translation. The consensus from such efforts including “The Lancet Neurology Commission” and current literature is that unmitigated cell death processes, incomplete debris clearance, aberrant neurotoxic immune, and glia cell response induce progressive tissue loss and spatiotemporal magnification of primary TBI. Our analysis suggests that the focus of neuroprotection research needs to shift from protecting dying and injured neurons at acute time points to modulating the aberrant glial response in sub-acute and chronic time points. One unexpected agent with neuroprotective properties that shows promise is transplantation of neural stem cells. In this review we present (i) a short survey of TBI epidemiology and summary of current care, (ii) findings of past neuroprotective clinical trials and possible reasons for failure based upon insights from human and preclinical TBI pathophysiology studies, including our group's inflammation-centered approach, (iii) the unmet need of TBI and unproven treatments and lastly, (iv) present evidence to support the rationale for sub-acute neural stem cell therapy to mediate enduring neuroprotection.
