Abstract
PURPOSE Traumatic intracranial hematoma (TICH) is a neurosurgical emergency with high mortality and morbidity. The time to operative decompression is a modifiable but inconsistently reported risk factor for TICH patients? OUTCOMES We aimed to provide contemporary time to evacuation data and long-term trends in timing of TICH evacuation in a trauma system. METHODS A 13-year retrospective cohort study ending in 2021 at a trauma system with one level-1 trauma center included all patients undergoing urgent craniotomy or craniectomy for evacuation of TICH. Demographics, injury severity and key timeframes of care were collected. Subgroups analyzed were polytrauma versus isolated head injury, direct admissions versus transfers and those who survived versus those who died. Linear regression of times from injury to operating room was performed. RESULTS Seventy-eight TICH patients (Age: 35 (22-56); 58 (74%) males; ISS: 25(25-41); AIS head: 5 (4-5); mortality: 21 (27%) patients) were identified. Initial GCS was 8 (3.25-14) which decreased to 3 (3-7) by arrival in the trauma center. There were 46 (59%) patients intubated prior to arrival. Median time from injury to operation was 4.88 (3.63-6.80) hours. Linear regression of injury to OR showed increasing times to operative intervention for direct admissions to the trauma center over the study period (p=0.04). There was no associated change in mortality or Glasgow outcome score over the same time. CONCLUSION This contemporary data shows timing from injury to evacuation is approaching 5 hours. Over the 13-year study period the time to operative intervention significantly increased for direct admissions. This study will guide our institutions response to TICH presentations in the future. Other trauma systems should critically appraise their results with the same reporting standard.

Temporal Delays in the Management of Traumatic Brain Injury: A Comparative Meta-Analysis of Global Literature. World Neurosurg 2024:S1878-8750(24)00827-1. [PMID: 38762022 DOI: 10.1016/j.wneu.2024.05.064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 05/09/2024] [Accepted: 05/10/2024] [Indexed: 05/20/2024]
Abstract
OBJECTIVE A meta-analysis was conducted to compare: 1) time from traumatic brain injury (TBI) to the hospital, and 2) time within the hospital to intervention or surgery, by country-level income, World Health Organization region, and healthcare payment system. METHODS A comprehensive literature search was conducted and followed by a meta-analysis comparing duration of delays (prehospital and intrahospital) in TBI management. Means and standard deviations were pooled using a random effects model and subgroup analysis was performed using R software. RESULTS Our analysis comprised 95,554 TBI patients from 45 countries. BY COUNTRY-LEVEL INCOME From 23 low- and middle-income countries, a longer mean time from injury to surgery (862.53 minutes, confidence interval [CI]: 107.42-1617.63), prehospital (217.46 minutes, CI: -27.34-462.25), and intrahospital (166.36 minutes, 95% CI: 96.12-236.60) durations were found compared to 22 high-income countries. BY WHO REGION African Region had the greatest total (1062.3 minutes, CI: -1072.23-3196.62), prehospital (256.57 minutes [CI: -202.36-715.51]), and intrahospital durations (593.22 minutes, CI: -3546.45-4732.89). BY HEALTHCARE PAYMENT SYSTEM Multiple-Payer Health Systems had a greater prehospital duration (132.62 minutes, CI: 54.55-210.68) but greater intrahospital delays were found in Single-Payer Health Systems (309.37 minutes, CI: -21.95-640.69). CONCLUSION Our study concludes that TBI patients in low- and middle-income countries within African Region countries face prolonged delays in both prehospital and intrahospital management compared to high-income countries. Additionally, patients within Single-Payer Health System experienced prolonged intrahospital delays. An urgent need to address global disparities in neurotrauma care has been highlighted.

Screening Performance of S100 Calcium-Binding Protein B, Glial Fibrillary Acidic Protein, and Ubiquitin C-Terminal Hydrolase L1 for Intracranial Injury Within Six Hours of Injury and Beyond. J Neurotrauma 2024; 41:349-358.

Abstract
The Scandinavian NeuroTrauma Committee (SNC) guidelines recommend S100 calcium-binding protein B (S100B) as a screening tool for early detection of Traumatic brain injury (TBI) in patients presenting with an initial Glasgow Coma Scale (GCS) of 14-15. The objective of the current study was to compare S100B's diagnostic performance within the recommended 6-h window after injury, compared with glial fibrillary acidic protein (GFAP) and UCH-L1. The secondary outcome of interest was the ability of these biomarkers in detecting traumatic intracranial pathology beyond the 6-h mark. The Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) core database (2014-2017) was queried for data pertaining to all TBI patients with an initial GCS of 14-15 who had a blood sample taken within 6 h of injury in which the levels of S100B, GFAP, and UCH-L1 were measured. As a subgroup analysis, data involving patients with blood samples taken within 6-9 h and 9-12 h were analyzed separately for diagnostic ability. The diagnostic ability of these biomarkers for detecting any intracranial injury was evaluated based on the area under the receiver operating characteristic curve (AUC). Each biomarker's sensitivity, specificity, and accuracy were also reported at the cutoff that maximized Youden's index. A total of 531 TBI patients with GCS 14-15 on admission had a blood sample taken within 6 h, of whom 24.9% (n = 132) had radiologically confirmed intracranial injury. The AUCs of GFAP (0.86, 95% confidence interval [CI]: 0.82-0.90) and UCH-L1 (0.81, 95% CI: 0.76-0.85) were statistically significantly higher than that of S100B (0.74, 95% CI: 0.69-0.79) during this time. There was no statistically significant difference in the predictive ability of S100B when sampled within 6 h, 6-9 h, and 9-12 h of injury, as the p values were >0.05 when comparing the AUCs. Overlapping AUC 95% CI suggests no benefit of a combined GFAP and UCH-L1 screening tool over GFAP during the time periods studied [0.87 (0.83-0.90) vs. 0.86 (0.82-0.90) when sampled within 6 h of injury, 0.83 (0.78-0.88) vs. 0.83 (0.78-0.89) within 6 to 9 h and 0.81 (0.73-0.88) vs. 0.79 (0.72-0.87) within 9-12 h]. Targeted analysis of the CENTER-TBI core database, with focus on the patient category for which biomarker testing is recommended by the SNC guidelines, revealed that GFAP and UCH-L1 perform superior to S100B in predicting CT-positive intracranial lesions within 6 h of injury. GFAP continued to exhibit superior predictive ability to S100B during the time periods studied. S100B displayed relatively unaltered screening performance beyond the diagnostic timeline provided by SNC guidelines. These findings suggest the need for a reevaluation of the current SNC TBI guidelines.

Abstract
BACKGROUND Most injury care research in low-income contexts such as Malawi is facility centric. Community-derived data is needed to better understand actual injury incidence, health system utilisation and barriers to seeking care following injury. METHODS We administered a household survey to 2200 households in Karonga, Malawi. The primary outcome was injury incidence, with non-fatal injuries classified as major or minor (> 30 or 1-29 disability days respectively). Those seeking medical treatment were asked about time delays to seeking, reaching and receiving care at a facility, where they sought care, and whether they attended a second facility. We performed analysis for associations between injury severity and whether the patient sought care, stayed overnight in a facility, attended a second facility, or received care within 1 or 2 h. The reason for those not seeking care was asked. RESULTS Most households (82.7%) completed the survey, with 29.2% reporting an injury. Overall, 611 non-fatal and four fatal injuries were reported from 531 households: an incidence of 6900 per 100,000. Major injuries accounted for 26.6%. Three quarters, 76.1% (465/611), sought medical attention. Almost all, 96.3% (448/465), seeking care attended a primary facility first. Only 29.7% (138/465), attended a second place of care. Only 32.0% (142/444), received care within one hour. A further 19.1% (85/444) received care within 2 h. Major injury was associated with being more likely to have; sought care (94.4% vs 69.8% p < 0.001), stayed overnight at a facility (22.9% vs 15.4% P = 0.047), attended a second place of care (50.3% vs 19.9%, P < 0.001). For those not seeking care the most important reason was the injury not being serious enough for 52.1% (74/142), followed by transport difficulties 13.4% (19/142) and financial costs 5.6% (8/142). CONCLUSION Injuries in Northern Malawi are substantial. Community-derived details are necessary to fully understand injury burden and barriers to seeking and reaching care.

Frailty Is Associated With Decreased Survival in Adult Patients With Nonoperative and Operative Traumatic Subdural Hemorrhage: A Retrospective Cohort Study of 381,754 Patients. ANNALS OF SURGERY OPEN 2023; 4:e348. [PMID: 38144491 PMCID: PMC10735122 DOI: 10.1097/as9.0000000000000348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Accepted: 09/06/2023] [Indexed: 12/26/2023] Open
Abstract
Objective We investigated frailty's impact on traumatic subdural hematoma (tSDH), examining its relationship with major complications, length of hospital stay (LOS), mortality, high level of care discharges, and survival probabilities following nonoperative and operative management. Background Despite its frequency as a neurosurgical emergency, frailty's impact on tSDH remains underexplored. Frailty characterized by multisystem impairments significantly predicts poor outcomes, necessitating further investigation. Methods A retrospective study examining tSDH patients ≥18 years and assigned an abbreviated injury scale score ≥3, and entered into ACS-TQIP between 2007 and 2020. We employed multivariable analyses for risk-adjusted associations of frailty and our outcomes, and Kaplan-Meier plots for survival probability. Results Overall, 381,754 tSDH patients were identified by mFI-5 as robust-39.8%, normal-32.5%, frail-20.5%, and very frail-7.2%. There were 340,096 nonoperative and 41,658 operative patients. The median age was 70.0 (54.0-81.0) nonoperative, and 71.0 (57.0-80.0) operative cohorts. Cohorts were predominately male and White. Multivariable analyses showed a stepwise relationship with all outcomes P < 0.001; 7.1% nonoperative and 14.9% operative patients had an 20% to 46% increased risk of mortality, that is, nonoperative: very frail (HR: 1.20 [95% CI: 1.13-1.26]), and operative: very frail (HR: 1.46 [95% CI: 1.38-1.55]). There were precipitous reductions in survival probability across mFI-5 strata. Conclusion Frailty was associated with major complications, LOS, mortality, and high level care discharges in a nationwide population of 381,754 patients. While timely surgery may be required for patients with tSDH, rapid deployment of point-of-care risk assessment for frailty creates an opportunity to equip physicians in allocating resources more precisely, possibly leading to better outcomes.

Increased distance or time from a major trauma centre in South Australia is not associated with worse outcomes after moderate to severe traumatic brain injury. Emerg Med Australas 2023; 35:998-1004. [PMID: 37461384 DOI: 10.1111/1742-6723.14281] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2023] [Revised: 06/25/2023] [Accepted: 06/26/2023] [Indexed: 11/18/2023]
Abstract
OBJECTIVE Considerations in traumatic brain injury (TBI) management include time to critical interventions and neurosurgical care, which can be influenced by the geographical location of injury. In Australia, these distances can be vast with varying degrees of first-responder experience. The present study aimed to evaluate the association that distance and/or time to a major trauma centre (MTC) had on patient outcomes with moderate to severe TBI. METHODS A retrospective cohort study was conducted using data from the Royal Adelaide Hospital's (RAH) Trauma Registry over a 3-year period (1 January 2018 to 31 December 2020). All patients with a moderate to severe TBI (Glasgow Coma Scale [GCS] ≤13 and abbreviated injury score head of ≥2) were included. The association of distance and time to the RAH and patient outcomes were compared by calculating the odds ratio utilising a logistic regression model. RESULTS A total of 378 patients were identified; of these, 226 met inclusion criteria and comprised our study cohort. Most patients were male (79%), injured in a major city (55%), with median age of 38 years old and median injury severity score (ISS) of 25. After controlling for age, ISS, ED GCS on arrival and pre-MTC intubation, increasing distance or time from injury site to the RAH was not shown to be associated with mortality or discharge destination in any of the models investigated. CONCLUSION Our analysis revealed that increasing distance or time from injury site to a MTC for patients with moderate to severe TBI was not significantly associated with adverse patient outcomes.

Abstract
OBJECTIVE Evaluate the association of survival with helicopter transport directly to a trauma center compared with ground transport to a non-trauma center (NTC) and subsequent transfer. SUMMARY BACKGROUND DATA Helicopter transport improves survival after injury. One potential mechanism is direct transport to a trauma center when the patient would otherwise be transported to an NTC for subsequent transfer. METHODS Scene patients 16 years and above with positive physiological or anatomic triage criteria within PTOS 2000-2017 were included. Patients transported directly to level I/II trauma centers by helicopter were compared with patients initially transported to an NTC by ground with a subsequent helicopter transfer to a level I/II trauma center. Propensity score matching was used to evaluate the association between direct helicopter transport and survival. Individual triage criteria were evaluated to identify patients most likely to benefit from direct helicopter transport. RESULTS In all, 36,830 patients were included. Direct helicopter transport was associated with a nearly 2-fold increase in odds of survival compared with NTC ground transport and subsequent transfer by helicopter (aOR 2.78; 95% CI 2.24-3.44, P <0.01). Triage criteria identifying patients with a survival benefit from direct helicopter transport included GCS≤13 (1.71; 1.22-2.41, P <0.01), hypotension (2.56; 1.39-4.71, P <0.01), abnormal respiratory rate (2.30; 1.36-3.89, P <0.01), paralysis (8.01; 2.03-31.69, P <0.01), hemothorax/pneumothorax (2.34; 1.36-4.05, P <0.01), and multisystem trauma (2.29; 1.08-4.84, P =0.03). CONCLUSIONS Direct trauma center access is a mechanism driving the survival benefit of helicopter transport. First responders should consider helicopter transport for patients meeting these criteria who would otherwise be transported to an NTC.

Abstract
OBJECTIVE Acute subdural hematoma (ASDH) leads to the highest mortality rates of all head injuries with secondary brain damage playing a pivotal role in terms of morbidity and mortality. In patients with ASDH, a delay in surgery leads to disproportional mortality. The benefit of (very) early therapy is therefore, a target of ongoing research. As the process of delayed brain damage in ASDH has not yet been described, this study therefore aimed to examine secondary lesion growth in an experimental rat model of ASDH to define the ideal timing for testing potential neuroprotective therapies. METHODS Cerebral blood flow was monitored during ASDH induction with 300 μl of autologous blood. Lesion growth was characterized using Hematoxylin-Eosin- , Cresyl-Violet-, and Fluoro-Jade B-staining for early signs of neuronal degeneration. Histological evaluations were performed between 15 minutes and 24 hours after ASDH. RESULTS There was a significant reduction of cerebral blood flow after ASDH. Fluoro-Jade B-positive cells were visible 15 minutes after ASDH in the lesioned hemisphere. Nonlinear growth of lesion volume from 3.7 ± 0.4 mm3 to 17.5 ± 0.6 mm3 was observed at 24 hours in Hematoxylin-Eosin-staining. CONCLUSIONS The most damage develops between 15 minutes and 1 hour and again between 2 and 6 hours after ASDH. The time course of lesion growth supports the approach of early surgery for patients. It furthermore constitutes a basis for further ASDH research with more clearly defined time windows for therapy in animal models.

Abstract
Acute subdural hematoma (ASDH) is the most frequent intracranial traumatic lesion requiring surgery in high-income countries. To date, uncertainty remains regarding the odds of mortality or functional outcome of patients with ASDH, regardless of whether they are operated on. This review aims to shed light on the clinical and radiologic factors associated with ASDH outcome. A scoping review was conducted on Medline database from inception to 2023. This review yielded 41 patient series. In the general population, specific clinical (admission Glasgow Coma Scale [GCS], abnormal pupil exam, time to surgery, decompressive craniectomy, raised postoperative intracranial pressure) and radiologic (ASDH thickness, midline shift, thickness/midline shift ratio, uncal herniation, and brain density difference) factors were associated with mortality (grade III). Other clinical (admission GCS, decompressive craniectomy) and radiologic (ASDH volume, thickness/midline shift ratio, uncal herniation, loss of basal cisterns, petechiae, and brain density difference) factors were associated with functional outcome (grade III). In the elderly, only postoperative GCS and midline shift on brain computed tomography were associated with mortality (grade III). Comorbidities, abnormal pupil examination, postoperative GCS, intensive care unit hospitalization, and midline shift were associated with functional outcome (grade III). Based on these factors, the SHE (Subdural Hematoma in the Elderly) and the RASH (Richmond Acute Subdural Hematoma) scores could be used in daily clinical practice. This review has underlined a few supplementary factors of prognostic interest in patients with ASDH, and highlighted two predictive scores that could be used in clinical practice to guide and assist clinicians in surgical indication.

Abstract
Introduction The Golden Hour is a term used in the trauma setting to refer to the first 60 minutes after injury. Traditionally, definitive care within this period was believed to dramatically increase a patient's survival. Though the period of 60 minutes is unlikely to represent a point of distinct inflection in survival, the effect of time to definitive care on survival remains incompletely understood. This study aims to measure the association of time to definitive hemostasis with mortality in patients with solid organ injuries as well as the effect of survival bias and a form of selection bias known as indication by severity on the relationship between time to treatment and survival. Methodology This is a retrospective cohort study using data obtained from the American College of Surgeons National Trauma Data Bank (NTDB) from the years 2017 through 2019 selecting patients treated for blunt liver, spleen, or kidney injury who required angioembolization or surgical hemostasis within six hours. A Cox proportional hazards regression was used to analyze time to death. The association of probability of death with time was examined with a multivariate logistic regression initially treating the relationship as linear and subsequently transforming time to hemostasis with restricted cubic splines to model a non-linear association with the outcome. To model survival and indication by severity bias, we created a computer-generated data set and used LOESS regressions to display curves of the simulated data. Results The multivariate Cox proportional hazards analysis shows a coefficient of negative 0.004 for minutes to hemostasis with an adjusted hazard ratio of 0.9959 showing the adjusted hazard of death slightly diminishes with each increasing minute to hemostasis. The likelihood ratio chi-square difference between the model with time to hemostasis included as a linear term versus the model with the restricted cubic spline transformation is 97.46 (p<0.0001) showing the model with restricted cubic splines is a better fit for the data. The computer-generated data simulating treatment of solid organ injury with no programmed bias displays an almost linear association of mortality with increased treatment delay. When indications by severity bias and survival bias are introduced, the risk of death decreases with time to hemostasis as in the real-world data. Conclusion Decreasing mortality with increasing delay to hemostasis in trauma patients with solid organ injury is likely due to confounding due to indication by severity and survival bias. After taking these biases into account, the association of delayed hemostasis with better survival is not likely due to the benefit of delay but rather the delay sorts patients by severity of injury with those more likely to die being treated first. These biases are extremely difficult to eliminate which limits the ability to measure the true effect of delay with retrospective data. The findings may however be of value as a predictive model to anticipate the acuity of a patient after an interval of unavoidable delay such as with a long transfer time.

Mire D, Chapple AG, Christensen BJ. Does Preoperative Surgical Delay Lead to Increased Postsurgical Length of Stay or Reoperation in Patients With Severe Odontogenic Infections? J Oral Maxillofac Surg 2023; 81:1161-1169. [PMID: 37348841 DOI: 10.1016/j.joms.2023.06.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 05/31/2023] [Accepted: 06/07/2023] [Indexed: 06/24/2023]
Abstract
BACKGROUND While severe odontogenic infections can be life-threatening and emergent surgery can be required more often, surgical management in the operating room (OR) is completed as soon as feasible. However, provider schedules and OR availability can occasionally lead to longer delays before surgery, but their effect on outcomes is unknown. PURPOSE The purpose of this study was to determine the association of preoperative surgical delay with postsurgical length of stay (LOS) and reoperation in patients with severe odontogenic infections. STUDY DESIGN, SETTING, SAMPLE The authors conducted a retrospective cohort study consisting of all adult patients treated in the OR with incision and drainage for odontogenic infections from 1/1/2015 to 7/30/2021 at a large, urban academic hospital. PREDICTOR VARIABLE The primary predictor variable was the length of presurgical delay-the number of hours between arrival in the emergency department and the start of surgery. MAIN OUTCOME VARIABLES The primary outcome variable was the postsurgical LOS and the secondary outcome variable was the rate of reoperation. COVARIATES Demographics, medical history, exam findings, diagnosis, and treatment-related variables were also analyzed. ANALYSES Descriptive and bivariate analyses were performed along with multivariable linear and logistic regression. A P value of < .05 was considered significant. RESULTS There were 401 patients included in the study with 50.9% men and a mean age of 39.1 years. Increased length of presurgical delay (hours) was associated with a decreased postsurgical LOS (β = -0.05 days, P = .01) and length of presurgical delay was not associated with reoperation (P = .51) in the unadjusted analyses. However, length of presurgical delay was not found to be associated with either LOS (β = -0.02, 95% confidence interval (CI) -0.05 to 0.01, P = .12) or reoperation (adjusted odds ratio (aOR) 1.0, 95% CI 0.96 to 1.02, P = .67) in the adjusted analyses. CONCLUSIONS AND RELEVANCE The association of decreased length of presurgical delay with increased postsurgical LOS in the unadjusted analysis could reflect the practice of rapid intervention for the most ill patients. After adjusting for number of spaces, a primary indicator of infection severity, length of presurgical delay was not associated with either LOS or return to the operating room.

Abstract
INTRODUCTION Early diagnosis and intervention by visiting the emergency department (ED) are important for traumatic brain injury (TBI). We evaluate the factors associated with delayed ED visits in patients with intracranial TBI. METHODS A retrospective multicenter observational study using the ED-based injury in-depth surveillance database (EDIIS) was designed. Patients with intracranial TBI with an alert mentality at ED presentation from 2014 to 2019 were enrolled. Patients were categorized into four groups according to ED visit time after injury (<1 h, 1-3 h, 3-12 h, and >12 h). ED visits after 12 h were defined as delayed ED visits. The factors associated with delayed ED visits were identified using multivariable logistic regression analysis. RESULTS Among 15,620 patients with TBI enrolled in the final analysis, 2,190 (14.0%) visited the ED 12 h after injury. Multivariable analysis identified the following factors as independent predictors for delayed ED visit such as unintentionally struck by or against an object or unintentional fall as a trauma mechanism, injury during ordinary activities, indoor injury, injury during nighttime, winter season, combined subdural hemorrhage and epidural hemorrhage. CONCLUSION In patients with intracranial TBI with an alert mentality, multiple factors related to patient demographics and injury characteristics were associated with the time interval from injury to ED visit.

Abstract
BACKGROUND Acute subdural hematomas (ASDH) are found frequently following traumatic brain injury (TBI) and they are considered the most lethal type of mass lesions. The decision to perform a procedure to evacuate ASDH and the approach, either via craniotomy or decompressive craniectomy (DC), remains controversial. METHODS We reviewed a prospectively collected series of 343 moderate to severe TBI patients in whom ASDH was the main lesion (ASDH volumes ≥10 cc). Patients with early comfort measures (early mortality prediction >50% and not ICP monitored), bilateral ASDH or the presence of another intracranial hematoma with volumes exceeding two times the volume of the ASDH were excluded. Among them, 112 were managed conservatively, 65 underwent ASDH evacuation by craniotomy and 166 by DC (103 pre-emptive DC, 63 obligatory DC). We calculated the average treatment effect by propensity score (PS) analysis using the following covariates: age, year, hypoxia, shock, pupils, major extracranial injury, motor score, midline shift, ASDH volume, swelling, intraventricular and subarachnoid hemorrhage presence. Then, multivariable binary regression and ordinal logistic regression analysis were performed to estimate associations between predictors and mortality and 12 months-GOS respectively. The patients' inverse probability weights were included as an independent variable in both regression models. RESULTS The main variables associated with outcome were year, age, falls from patient´s own height, hypoxia, early deterioration, pupillary abnormalities, basal cistern effacement, compliance to ICP monitoring guidelines and type of surgical approach (craniotomy and pre-emptive DC). CONCLUSIONS According to sliding dichotomy analysis, we found that patients in the intermediate or worst bands of unfavorable outcome prognosis seemed to achieve better than expected outcome if they underwent pre-emptive DC rather than craniotomy.

Abstract
OBJECTIVE For critically ill patients in remote areas, we assessed the association of transport delay via fixed wing air ambulance on 30-day mortality, excluding interhospital transports. METHODS This was a retrospective cohort analysis of all such adult transports in Manitoba, Canada, over 5.4 years. Causal mediation analysis was used, with the Acute Physiology and Chronic Health Evaluation II Acute Physiology Score at the destination intensive care unit as the mediator. The covariates were age, sex, comorbidities, socioeconomic status, and physiologic variables from the sending site. RESULTS The primary cohort was composed of 554 patients; 113 (20.4%) died within 30 days. The total transport delay (mean ± standard deviation) was 5.1 ± 1.7 hours. Compared with no delay, the average 5-hour transport delay was associated with an odds ratio for mortality of 1.34 with a 95% confidence interval from 40% lower to 270% higher, with 60% of the influence of total travel time attributable to worsening of patients' acute physiologic status during the delay in intensive care unit admission due to transport. CONCLUSIONS Although these findings provide insufficient evidence for an effect of fixed wing air transport delay on mortality among critically ill patients, they underscore the need for additional and larger studies on this topic.

Abstract
The rationale of performing surgery for acute subdural hematoma (ASDH) to reduce mortality is often compared with the self-evident effectiveness of a parachute when skydiving. Nevertheless, it is of clinical relevance to estimate the magnitude of the effectiveness of surgery. The aim of this study is to determine whether surgery reduces mortality in traumatic ASDH compared with initial conservative treatment. A systematic search was performed in the databases IndexCAT, PubMed, Embase, Web of Science, Cochrane library, CENTRAL, Academic Search Premier, Google Scholar, ScienceDirect, and CINAHL for studies investigating ASDH treated conservatively and surgically, without restriction to publication date, describing the mortality. Cohort studies or trials with at least five patients with ASDH, clearly describing surgical, conservative treatment, or both, with the mortality at discharge, reported in English or Dutch, were eligible. The search yielded 2025 reports of which 282 were considered for full-text review. After risk of bias assessment, we included 102 studies comprising 12,287 patients. The data were synthesized using meta-analysis of absolute risks; this was conducted in random-effects models, with dramatic effect estimation in subgroups. Overall mortality in surgically treated ASDH is 48% (95% confidence interval [CI] 44-53%). Mortality after surgery for comatose patients (Glasgow Coma Scale ≤8) is 41% (95% CI 31-51%) in contemporary series (after 2000). Mortality after surgery for non-comatose ASDH is 12% (95% CI 4-23%). Conservative treatment is associated with an overall mortality of 35% (95% CI 22-48%) and 81% (95% CI 56-98%) when restricting to comatose patients. The absolute risk reduction is 40% (95% CI 35-45%), with a number needed to treat of 2.5 (95% CI 2.2-2.9) to prevent one death in comatose ASDH. Thus, surgery is effective to reduce mortality among comatose patients with ASDH. The magnitude of the effect is large, although the effect size may not be sufficient to overcome any bias.

Abstract
OBJECTIVE Prehospital medicine has struggled to manage critical patients without the resources available to hospital-based teams. Point-of-care ultrasound could bridge this resource gap by providing critical insight into the pathology of trauma patients. This study aimed to determine if early positive extended focused assessment with sonography in trauma (eFAST) identification would lead to improved patient outcomes. METHODS This is a prospective observational trial that took place from February 1, 2019, to August 13, 2021. Paramedics, with no prior ultrasound experience, at a single ground ambulance agency were trained in obtaining and interpretating eFAST examinations. RESULTS Thirty-seven paramedics were trained and performed a total of 502 eFAST examinations with a total correct interpretation rate of 97.35%. There was a sensitivity of 30.0%/75.0%, specificity of 98.75%/94.05%, a positive predictive value of 33.33%/37.5%, a negative predictive value of 98.55%/98.75%, a positive likelihood ratio of 24.05/12.6, and a negative likelihood ratio of 0.71/0.27 for all exam/patient-only scans. The time spent on scene for eFAST and non-eFAST calls was not significantly different (F3, 2,512 = 2.59, P = .051, η2 = .003). CONCLUSION Although we were able to show successful training and interpretation of eFAST with paramedics, given the low prevalence of disease, our study did not show eFAST use improving patient outcome. However, the large likelihood ratio suggests its benefit may lie with appropriate trauma resource utilization.

Abstract
OBJECTIVES The burden of pediatric trauma and emergency, including pediatric surgical emergencies in low middle income countries (LMIC) is high. The goal of Pediatric Acute Surgical Support (PASS) course is to prepare caregivers in LMIC for the acute management of life-threatening pediatric surgical emergencies. We aim to show the feasibility of its initial deployment. METHODS PASS was developed in 2016 with LMIC faculty from a teaching children hospital CH. The course contents consisted of a mix of didactic materials for serious general neonatal and pediatric surgery modified PALS/ATLS, in-person multidisciplinary team-based skill stations, interactive clinical scenarios and simulated trauma cases. The course was subsequently revised and delivered to 92 learners in four classes of 2.5-days sessions at two CHs between 2017 and 2019. Learners' demographics, written exams, team-based case performance, and post-course survey data were prospectively collected and retrospectively analyzed. RESULTS Physician (60%) and nurse learners (40%) from pediatric critical care (36%), surgery (23%), emergency medicine (20%) and anesthesiology (9%) had 3.6 +/- 3.6 years of clinical practice; pre- and post-course written exam score of 55.4+/-15.5% vs 71.6+/-12.8%, team-based trauma scenario management 22.6 ± 7.8% vs 54.7 ± 16.6% and team-based dynamic scores 17+/- 10% vs 53.3+/- 15.5%, respectively (p<0.0001). Self-reported satisfaction scores were ≥ 95% for course method, level of difficulty, clinical applicability, and quality of instructors. CONCLUSION PASS is well-received by LMIC learners, with short-term improvement in knowledge-, team-based management of acute pediatric surgery emergencies; and has the potential to be a model of horizontal capacity building for pediatric surgery in LMIC.

Factors Associated with an Increase in On-Site Time of Pediatric Trauma Patients in a Prehospital Setting: A Nationwide Observational Study in Japan. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9111658. [PMID: 36360384 PMCID: PMC9688461 DOI: 10.3390/children9111658] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Revised: 10/27/2022] [Accepted: 10/28/2022] [Indexed: 11/06/2022]
Abstract
The factors that prolong the on-site time in pediatric trauma cases in a prehospital setting are unknown. We investigated these factors using a national trauma registry in Japan. We identified pediatric trauma patients aged ≤18 years, from January 2004 to May 2019. We categorized cases into shorter (≤13 min) and longer (>13 min) prehospital on-site time groups. We performed multivariable logistic regression analysis with multiple imputations to assess the factors associated with longer prehospital on-site time. Overall, 14,535 patients qualified for inclusion. The median prehospital on-site time was 13 min. In the multivariable logistic regression analysis, the longer prehospital on-site time was associated with higher age; suicide (Odds ratio [OR] 1.27; 95% confidence interval [CI] 1.03−1.57); violence (OR 1.74; 95%CI 1.27−2.38); higher revised trauma score, abbreviated injury scale > 3 in the spine (OR 1.25; 95%CI 1.04−1.50), upper extremity (OR 1.26; 95%CI 1.11−1.44), and lower extremity (OR 1.25; 95%CI 1.14−1.37); immobilization (OR 1.16; 95%CI 1.06−1.27); and comorbid mental retardation (OR 1.56; 95%CI 1.11−2.18). In light of these factors, time in the field could be reduced by having more pediatric emergency physicians and orthopedic surgeons available.

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.

Abstract
INTRODUCTION While timely specialized care can contribute to improved outcomes following traumatic brain injury (TBI), this condition remains the most common cause of post-injury death worldwide. The purpose of this study was to investigate the difference in mortality between regional trauma centers in Sweden (which provide neurosurgical services round the clock) and non-trauma centers, hypothesizing that 1-day and 30-day mortality will be lower at regional trauma centers. PATIENTS AND METHODS This retrospective cohort study used data extracted from the Swedish national trauma registry and included adults admitted with severe TBI between January 2014 and December 2018. The cohort was divided into two subgroups based on whether they were treated at a trauma center or non-trauma center. Severe TBI was defined as a head injury with an AIS score of 3 or higher. Poisson regression analyses with both univariate and multivariate models were performed to determine the difference in mortality risk [Incidence Rate Ratio (IRR)] between the subgroups. As a sensitivity analysis, the inverse probability of treatment weighting (IPTW) method was used to adjust for the effects of confounding. RESULTS A total of 3039 patients were included. Patients admitted to a trauma center had a lower crude 30-day mortality rate (21.7 vs. 26.4% days, p = 0.006). After adjusting for confounding variables, patients treated at regional trauma center had a 28% [adj. IRR (95% CI): 0.72 (0.55-0.94), p = 0.015] decreased risk of 1-day mortality and an 18% [adj. IRR (95% CI): 0.82 (0.69-0.98)] reduction in 30-day mortality, compared to patients treated at a non-trauma center. After adjusting for covariates in the Poisson regression analysis performed after IPTW, admission and treatment at a trauma center were associated with a 27% and 17% reduction in 1-day and 30-day mortality, respectively. CONCLUSION For patients suffering a severe TBI, treatment at a regional trauma center confers a statistically significant 1-day and 30-day survival advantage over treatment at a non-trauma center.

Abstract
BACKGROUND Civilian and military populations alike are increasingly faced with undesirable situations in which prehospital and definitive care times will be delayed. The Western Cape of South Africa has some similarities in capabilities, injury profiles, resource-limitations, and system configuration to U.S. military prolonged casualty care (PCC) settings. This study provides an initial description of civilians in the Western Cape who experience PCC and compares the PCC and non-PCC populations. METHODS We conducted a 6 month analysis of an on-going, prospective, large-scale epidemiologic study of prolonged trauma care in the Western Cape ('EpiC'). We define PCC as ≥10 hours from injury to arrival at definitive care. We describe patient characteristics, critical interventions, key times, and outcomes as they may relate to military PCC and compare these using chi-squared and Wilcoxon tests. We estimated the associations between PCC status and the primary and secondary outcomes using logistic regression models. RESULTS 146 of 995 patients experienced PCC. The PCC group, compared to non-PCC, were more critically injured (66% vs 51%), received more critical interventions (36% vs 29%), had a greater proportionate mortality (5% vs 3%), longer hospital stays (3 vs 1 day), and higher SOFA scores (5 vs 3). The odds of 7-day mortality and a SOFA score ≥ 5 were 1.6 (OR: 1.59; 0.68, 3.74) and 3.6 (OR: 3.69; 2.11, 6.42) times higher, respectively, in PCC versus non-PCC patients. CONCLUSIONS EpiC enrolled critically injured patients with PCC who received resuscitative interventions. PCC patients had worse outcomes than non-PCC. EpiC will be a useful platform to provide on-going data for PCC relevant analyses, for future PCC-focused interventional studies, and to develop PCC protocols and algorithms. Findings will be relevant to the Western Cape, South Africa, other LMICs, and military populations experiencing prolonged care. LEVEL OF EVIDENCE III; prospective comparative study.

Access to care following injury in Northern Malawi, a comparison of travel time estimates between Geographic Information System and community household reports. Injury 2022; 53:1690-1698.

Abstract
INTRODUCTION Injuries disproportionately impact low- and middle-income countries like Malawi. The Lancet Commission on Global Surgery's indicators include the population proportion accessing laparotomy and open fracture care, key trauma interventions, within two hours. The "Golden Hour" for receiving facility-based resuscitation also guides injury care system strengthening. Firstly, we estimated the proportion of the local population able to reach primary, secondary and tertiary facility care within two and one hours using Geographic Information System (GIS) analysis. Secondly, we compared community household-reported with GIS-estimated travel time. METHODS Using information from a Health and Demographic Surveillance Site (Karonga, Malawi) on road network, facility location, and local staff-estimated travel speeds, we used a GIS-generated friction surface to calculate the shortest travel time from all households to each facility serving the population. We surveyed community households who reported travel time to their preferred, closest, government secondary and tertiary facilities. For recently injured community members, time to reach facility care was recorded. To assess the relationship between community household-reported travel time and GIS-estimated travel time, we used linear regression to generate a proportionality constant. To assess associations and agreement between injured patient-reported and GIS-estimated travel time, we used Kendall rank and Cohen's kappa tests. RESULTS Using GIS, we estimated 79.1% of households could reach any secondary facility, 20.5% the government secondary facility, and 0% the government tertiary facility, within two hours. Only 28.2% could reach any secondary facility within one hour, 0% for the government secondary facility. Community household-reported travel time exceeded GIS-estimated travel time. The proportionality constant was 1.25 (95%CI 1.21-1.30) for the closest facility, 1.28 (95%CI 1.23-1.34) for the preferred facility, 1.45 (95%CI 1.33-1.58) for the government secondary facility, and 2.12 (95%CI 1.84-2.41) for tertiary care. Comparing injured patient-reported with GIS-estimated travel time, the correlation coefficient was 0.25 (SE 0.047) and Cohen's kappa was 0.15 (95%CI 0.078-0.23), suggesting poor agreement. DISCUSSION Most households couldn't reach government secondary care within recognised thresholds indicating poor temporal access. Since GIS-estimated travel time was shorter than community-reported travel time, the true proportion may be lower still. GIS derived estimates of population emergency care access in similar contexts should be interpreted accordingly.

Abstract
ABSTRACT Trauma-hemorrhage is the leading cause of prehospital and early in-hospital deaths, while also significantly contributing to the later development of multisystem organ dysfunction/failure and sepsis. Common and advanced resuscitative methods would potentially demonstrate benefits in the prehospital setting; however, they face a variety of barriers to application and implementation. Thus, a dialogue around a novel adjunct has arisen, sex hormone therapy. Proposed candidates include estradiol and its derivatives, metoclopramide hydrochloride/prolactin, dehydroepiandrosterone, and flutamide; with each having demonstrated a range of salutary effects in several animal model studies. Several retrospective analyses have observed a gender-based dimorphism in mortality following trauma-hemorrhage, thus suggesting that estrogens contribute to this pattern. Trauma-hemorrhage animal models have shown estrogens offer protective effects to the cardiovascular, pulmonary, hepatic, gastrointestinal, and immune systems. Additionally, a series of survival studies utilizing 17α-ethinylestradiol-3-sulfate, a potent, water-soluble synthetic estrogen, have demonstrated a significant survival benefit and beneficial effects on cardiovascular function. This review presents the findings of retrospective clinical studies, preclinical animal studies, and discusses how and why 17α-ethinylestradiol-3-sulfate should be considered for investigation within a prospective clinical trial.

Abstract
BACKGROUND Low-middle-income countries experience among the highest rates of traumatic brain injury in the world. Much of this burden may be preventable with faster intervention, including reducing the time to definitive care. This study examines the relationship between traumatic brain injury severity and time to definitive care in major trauma hospitals in three low-middle-income countries. METHODS A prospective traumatic brain injury registry was implemented in six trauma hospitals in Armenia, Georgia and the Republic of Moldova for 6 months in 2019. Brain injury severity was measured using the Glasgow Coma Scale (GCS) at admission. Time to definitive care was the time from injury until arrival at the hospital. Cox proportionate hazards models predicted time to care by severity, controlling for age, sex, mechanism, mode of transportation, location of injury and country. RESULTS Among 1135 patients, 749 (66.0%) were paediatric and 386 (34.0%) were adults. Falls and road traffic were the most common mechanisms. A higher proportion of adult (23.6%) than paediatric (5.4%) patients had GCS scores indicating moderate (GCS 9-11) or severe injury (GCS 0-8) (p<0.001). Less severe injury was associated with shorter times to care, while more severe injury was associated with longer times to care (HR=1.05, 95% CI 1.01 to 1.09). Age interacted with time to care, with paediatric cases receiving faster care. CONCLUSIONS Implementation of standard triage and transport protocols may reduce mortality and improve outcomes from traumatic brain injury, and trauma systems should focus on the most severe injuries.

Abstract
Abstract
Objective In patients with traumatic acute subdural hematoma (ASH), it has not been yet fully elucidated which patients can benefit from surgery or from clinical follow-up. This study was constructed to predict treatment modality and short-term prognosis in patients with ASH using their clinical, radiological, and biochemical laboratory findings during admission to hospital.
Methods Findings of patients with ASH determined on their CT scan between 2015 and 2018 were evaluated. Patients were grouped in terms of ASH-FOL (patients followed-up without surgery, n = 13), ASH-OP (patients treated surgically, n = 10), and ASH-INOP (patients considered as inoperable, n = 5) groups. They also were divided into “survived (n = 14)” and “nonsurvived (n = 14)” groups.
Results ASH developed as a result of fall from a height in 15 patients and traffic accidents in 13 patients. In deciding for surgery, it was determined that Glasgow coma scale (GCS) scores < 8, midline shift (MLS) level > 5 mm, MLS-hematoma thickness ratio > 0.22, leukocyte count > 12730 uL, and presence of anisocoria could be used as predictive markers. It was determined that GCS scores < 8, hematoma thickness value > 8 mm, and the presence of anisocoria could be considered as biomarkers in prediction of mortality likelihood.
Conclusion It could be suggested that GCS scores, MLS level, MLS-hematoma thickness ratio, presence of anisocoria, and leukocyte count value could help in determination of the treatment modality in patients with ASH. Additionally, GCS scores, hematoma thickness value, and presence of anisocoria could each be used as a marker in the prediction of early-stage prognosis and mortality likelihood of these patients.

Abstract
PURPOSE This study examined the association between lapsed time and trauma patients, suggesting that a shorter time to definitive care leads to a better outcome. METHODS We used the Pan-Asian Trauma Outcome Study registry to analyze a retrospective cohort of 963 trauma patients who received surgical intervention or transarterial embolization within 2 h of injury in Asian countries between January 2016 and December 2020. Exposure measurement was recorded every 30 min from injury to definitive care. The 30 day mortality rate and functional outcome were studied using the Modified Rankin Scale ratings of 0-3 vs 4-6 for favorable vs poor functional outcomes, respectively. Subgroup analyses of different injury severities and patterns were performed. RESULTS The mean time from injury to definitive care was 1.28 ± 0.69 h, with cases categorized into the following subgroups: < 30, 30-60, 60-90, and 90-120 min. For all patients, a longer interval was positively associated with the 30 day mortality rate (p = 0.053) and poor functional outcome (p < 0.05). Subgroup analyses showed the same association in the major trauma (n = 321, p < 0.05) and torso injury groups (n = 388, p < 0.01) with the 30 day mortality rate and in the major trauma (p < 0.01), traumatic brain injury (n = 741, p < 0.05), and torso injury (p < 0.05) groups with the poor functional outcome. CONCLUSION Even within 2 h, a shorter time to definitive care is positively associated with patient survival and functional outcome, especially in the subgroups of major trauma and torso injury.

Prepatching Reduces Paramedic In-Hospital Time for Emergent Interfacility Transfers of Patients Requiring Mechanical Ventilation or Vasopressors: A Retrospective Cohort Study. Air Med J 2021; 40:431-435.

Abstract
OBJECTIVE Regionalization of specialty medical services may necessitate an interfacility transfer. Prepatching is a model of care adopted by critical care transport organizations to reduce the transfer time to specialty care. In this model, paramedics communicate with a transport medical physician before arrival at the sending hospital to discuss a patient's condition and management plan, allowing paramedics to focus solely on packaging the patient when he or she arrives at the sending hospital. The objective of this study was to assess the impact of prepatching on paramedic in-hospital time for emergent interfacility transfers of patients requiring mechanical ventilation or vasopressor support. METHODS This is a retrospective cohort study of all emergent interfacility transfers by Ornge, the provincial critical care transport organization in Ontario, Canada, over a 4-year period. All patients over 18 years old who were either intubated or on vasopressor medications were included in the study population. Quantile regression was used to evaluate the impact of prepatching as well as patient and paramedic characteristics on paramedic in-hospital time. RESULTS A total of 4,466 emergent interfacility transports were included. Of these, 1,898 were completed with prepatching, and 2,568 were not. Vasopressor use was associated with significantly higher prepatching rates. Overall, prepatching reduced in-hospital time by 9 minutes at the 90th quantile across all patients. Increased in-hospital time was noted for patients on mechanical ventilation, on vasopressor medications, and transported by a fixed wing vehicle by 38, 29, and 49 minutes at the 90th quantile, respectively (P < .05). Conversely, patients transported by a critical care paramedic crew configuration were associated with a 27-minute decrease in in-hospital time at the 90th quantile compared with transport by an advanced care paramedic crew configuration (P < .05). CONCLUSION Prepatching reduced paramedic in-hospital time for emergent interfacility transports for patients who were mechanically ventilated or require vasopressors. These results suggest that prepatching can reduce the overall time to definitive care in high-risk patients, potentially improving patient outcomes in critically ill patients.

Abstract
BACKGROUND Delays in the transfers of injured patients are perceived to increase morbidity and mortality and drive initiatives to limit the emergency department length of stay (LOS) at referring facilities (RF). RF LOS >4 hours is used for performance improvement (PI) with a large review burden with few improvement opportunities. METHODS A statewide trauma registry 2013-2018 was used. Descriptive and inferential statistics including logistic regression were used to evaluate nongeriatric adult patients with ED LOS <12 hours. Paired data analyses utilizing prehospital (PH) and RF variables, vital signs (VS), Glasgow Coma Score-Motor component (GCS-M), RF LOS, mortality, trauma center hospital LOS (HLOS), and intensive care unit (ICU) LOS were performed. RESULTS 13,721 of 56,702 transfer patients were selected. Mortality fell over time in all abbreviated injury score groups. GCS-M and systolic blood pressure (SBP) were correlated with mortality in both prehospital and RF data and highest in patients with abnormal GCS-M or SBP in both settings (38.0%, 30.1%). Examination of mortality over time in the group with abnormal VS showed SBP as the only variable with increasing mortality related to RF LOS. Average HLOS and ICU LOS were longest in patients with abnormal PH and RF SBP and GCS-M. DISCUSSION Support for PI evaluation of RF LOS >4 hours was not identified. Increased survival over time is explained by early transfers of high mortality patients. Our data support existing efficient statewide transfers and recommend PI review of transfer patients with abnormal GCS-M and SBP in a narrower timeframe.

Abstract
BACKGROUND AND BURDEN Trauma with its early and late consequences disproportionately effects those from poor countries. The availability of effective orthopaedic and trauma care varies significantly across the globe. CHALLENGES The balancing out of quality care is required to reach the health-related UN development goal set out in 2015. A multifactorial approach addressing local, national and international aspects is key to improving the discrepancy seen between high- and low-income countries.

Abstract
BACKGROUND Although head injury (HI) from low- and middle-income countries (LMIC) heavily contributes to the global disease burden, studies are disproportionately less from this part of the world. Knowing the different epidemiological characteristics from high-income nations can target appropriate prevention strategies. This study aims to provide a comprehensive overview of the clinico-epidemiological data of HI patients, focusing on the existing challenges with possible solutions from a developing nation's perspective. METHODS This is a prospective, registry-based, observational study of HI in an Indian tertiary trauma-care center over 4 years. Various clinico-epidemiological parameters, risk factors, and imaging spectrum were analyzed in a multivariate model to identify the challenges faced by LMIC and discuss pragmatic solutions. RESULTS The study included a large-volume cohort of 14,888 patients. Notably, half of these patients belonged to mild HI, despite most were referred (90.3%) cases. Only one-third (30.8%) had severe HI. Less than a third reached us within 6 h of injury. Road traffic accidents (RTA) accounted for most injuries (61.1%), especially in the young (70.9%). Higher age, males, RTA, helmet non-usage, drunken driving, systemic injuries, and specific imaging features had an independent association with injury severity. CONCLUSIONS The study represents the much-needed, large-volume, epidemiological profile of HI from an LMIC, highlighting the suboptimal utilization of peripheral healthcare systems. Strengthening and integrating these facilities with the tertiary centers in a hub and enhanced spoke model, task sharing design, and efficient back-referrals promise effective neurotrauma care while avoiding overburden in the tertiary centers. Better implementation of road safety laws also has the potential to reduce the burden of HI.

Abstract
Objective To analyze clinical, surgical and outcome predictive factors of operated acute subdural hematoma (SDH) cases for prognostication and surgical outcome prediction.
Material and Methods This retrospective study includes 114 patients operated for acute SDH in the Department of Neurosurgery of IMS BHU, Varanasi, India, a tertiary care center, between 1 August 2018 and 1 November 2019. Each patient was evaluated for age, sex, mode of injury, localization of hematoma, clinical presentation, comorbidity, severity of injury, best motor response, CT findings, and Glasgow outcome scale (GOS) at discharge. The outcome was also evaluated by further making a dichotomized group using GOS in death/dependent (1–3) versus independent (4–5). Statistical tests were done using the GraphPad Prism version 8.3.0.
Results The most common age group operated upon in this study was the 40 to 60 years age group (n = 45, 39.48%). Males were 78% with male to female ratio of 3.56:1. The most common clinical presentation was altered sensorium (98.25%). The most common comorbidity was hypertension (n = 32, 28.07%). GCS at admission, severity of injury, pupillary changes, and best motor response (p < 0.0001) were significantly associated with surgical outcome.
Conclusion GCS at admission, severity of injury, pupillary changes, and best motor response were significantly (p < 0.05) associated with surgical outcome. Age and gender of patients were not found to be significantly associated.

Abstract
BACKGROUND The COVID19 lockdown has altered the dynamics of living. Its collateral fallout on head injury care has not been studied in detail, especially from low- and middle-income countries, possibly overwhelmed more than developed nations. Here, we analyze the effects of COVID19 restrictions on head injury patients in a high-volume Indian referral trauma center. METHODS From the prospective trauma registry, clinico-epidemiological and radiological parameters of patients managed during 190 days before and 190 days during COVID19 phases were studied. As an indicator of care, the inpatient mortality of patients with severe HI was also compared with appropriate statistical analyses. RESULTS Of the total 3372 patients, there were 83 head injury admissions per week before COVID19 restrictions, which decreased to 33 every week (60% drop) during the lock phases and stabilized at 46 per week during the unlock phases. COVID19 restrictions caused a significant increase in the proportion of patients arriving directly without resuscitation at peripheral centers and later than 6 h of injury. Though the most common mechanism was vehicular, a relative increase in the proportion of assaults was noted during COVID19. There was no change in the distribution of mild, moderate, and severe injuries. Despite a decrease in the percentage of patients with systemic illnesses, severe head injury mortality was significantly more during the lock phases than before COVID19 (59% vs. 47%, p = 0.02). CONCLUSIONS COVID19 restrictions have amplified the already delayed admission among patients of head injury from north-west India. The severe head injury mortality was significantly greater during lock phases than before COVID19, highlighting the collateral fallout of lockdown. Pandemic control measures in the future should not ignore the concerns of trauma emergency care.

Abstract
BACKGROUND Evaluation of trainee performance remains a challenge in resident education, particularly for systems-based practice (SysBP) metrics including care coordination and interdisciplinary teamwork. Time to intervention is an important modifiable outcome variable in severe traumatic brain injury (TBI) and may serve as a trackable metric for SysBP evaluation. METHODS We retrospectively studied time from computed tomography head scan to surgical incision (CTH-INC, minutes) among neurosurgical trainees treating patients with emergently operative TBI as a proxy SysBP measure. Our institutional operative database was utilized to identify all emergent TBI cases between July 2015 and June 2020. Patients evaluated by program year (PGY)-2 residents proceeding directly to the operating room from the emergency department were included. Statistical analysis was performed using linear regression. RESULTS One hundred sixty-six cases triaged by 14 PGY-2 neurosurgical trainees were analyzed. Median CTH-INC was 104 minutes (interquartile range, 82-136 minutes). CTH-INC improved 20.1% over the academic year (95% confidence interval, 4.3%-33.2%, P = 0.015). Between the first and second 6-month periods, the rate of CTH-INC within 90 minutes (29% vs. 46%, P = 0.04) improved. On a per-individual PGY-2 basis, median CTH-INC ranged from 83-127 minutes, 25th percentile CTH-INC ranged from 62-108 minutes, and fastest CTH-INC ranged from 45-92 minutes. CONCLUSIONS CTH-INC is an objective and trackable proxy measure for evaluating SysBP during neurosurgical training. Use of CTH-INC or other time metrics in resident evaluations should not supersede the safe and effective delivery of patient care.

Abstract
Epidural hematomas (EDHs) and subdural hematomas (SDHs), or so-called extra-axial bleedings, are common clinical entities after a traumatic brain injury (TBI). A forensic pathologist often analyzes cases of traumatic EDHs or SDHs due to road accidents, suicides, homicides, assaults, domestic or on-the-job accidents, and even in a medical responsibility scenario. The aim of this review is to give an overview of the published data in the medical literature, useful to forensic pathologists. We mainly focused on the data from the last 15 years, and considered the most updated protocols and diagnostic-therapeutic tools. This study reviews the epidemiology, outcome, and dating of extra-axial hematomas in the adult population; studies on the controversial interdural hematoma are also included.

Delayed Neurosurgical Intervention in Traumatic Brain Injury Patients Referred From Primary Hospitals Is Not Associated With an Unfavorable Outcome. Front Neurol 2021; 11:610192.

Abstract
Background: Secondary transports of patients suffering from traumatic brain injury (TBI) may result in a delayed management and neurosurgical intervention, which is potentially detrimental. The aim of this study was to study the effect of triaging and delayed transfers on outcome, specifically studying time to diagnostics and neurosurgical management. Methods: This was a retrospective observational cohort study of TBI patients in need of neurosurgical care, 15 years and older, in the Stockholm Region, Sweden, from 2008 throughout 2014. Data were collected from pre-hospital and in-hospital charts. Known TBI outcome predictors, including the protein biomarker of brain injury S100B, were used to assess injury severity. Characteristics and outcomes of direct trauma center (TC) and those of secondary transfers were evaluated and compared. Functional outcome, using the Glasgow Outcome Scale, was assessed in survivors at 6–12 months after trauma. Regression models, including propensity score balanced models, were used for endpoint assessment. Results: A total of n = 457 TBI patients were included; n = 320 (70%) patients were direct TC transfers, whereas n = 137 (30%) were secondary referrals. In all, n = 295 required neurosurgery for the first 24 h after trauma (about 75% of each subgroup). Direct TC transfers were more severely injured (median Glasgow Coma Scale 8 vs. 13) and more often suffered a high energy trauma (31 vs. 2.9%) than secondary referrals. Admission S100B was higher in the TC transfer group, though S100B levels 12–36 h after trauma were similar between cohorts. Direct or indirect TC transfer could be predicted using propensity scoring. The secondary referrals had a shorter distance to the primary hospital, but had later radiology and surgery than the TC group (all p < 0.001). In adjusted multivariable analyses with and without propensity matching, direct or secondary transfers were not found to be significantly related to outcome. Time from trauma to surgery did not affect outcome. Conclusions: TBI patients secondary transported to a TC had surgical intervention performed hours later, though this did not affect outcome, presumably demonstrating that accurate pre-hospital triaging was performed. This indicates that for selected patients, a wait-and-see approach with delayed neurosurgical intervention is not necessarily detrimental, but warrants further research.

Abstract
BACKGROUND The management of hypotensive patients with severe combined head and abdominal trauma is challenging, regarding the need, timing, and sequence of craniotomy or laparotomy. The purpose of the present study was to determine whether rare situations requiring craniotomy prior to laparotomy can be identified on admission with simple clinical parameters. We hypothesized that hypotension is rarely associated with the need of a combined procedure, especially in patients with mildly depressed consciousness. METHODS National Trauma Data Bank study, including adult blunt trauma patients with combined severe head (Abbreviated Injury Scale score, ≥ 3) and abdominal injury (Abbreviated Injury Scale score, ≥ 3). Data collection included demographic and clinical characteristics, laparotomy, and craniotomy within 24 hours of admission, types of intracranial pathologies, survival, and hospital stay. Multivariate regression analysis was used to determine factors predictive for the need of both operative procedures. RESULTS Of 25,585 patients with severe combined head and abdominal trauma, 8,744 (34.2%) needed only laparotomy, 534 (2.1%) only craniotomy, and 394 (1.5%) required both procedures within 24 hours of admission. In the subgroup of 4,667 hypotensive patients, 2,421 (51.9%) underwent only laparotomy, 54 (1.2%) only craniotomy, and 79 (1.7%) both procedures within 24 hours of admission. Only 5 (0.7%) of 711 hypotensive patients with Glasgow Coma Scale (GCS) score above 8 who required a laparotomy also needed a craniotomy. Among clinical parameters available on patient's arrival, GCS score of 7 to 8 was independently associated with the highest need for craniotomy in hypotensive patients requiring laparotomy (odds ratio, 7.94; p = 0.004). CONCLUSION The need for craniotomy in patients with severe combined head and abdominal injury requiring exploratory laparotomy is very low. In hypotensive patients requiring laparotomy, GCS score of 7 to 8 was an independent predictor of the need for craniotomy. In hemodynamically unstable patients with a GCS score greater than 8, it may be safer to proceed with a laparotomy first and address the head with a computed tomography scan at a later stage. LEVEL OF EVIDENCE Therapeutic, Level IV.

Abstract
BACKGROUND Annually, over 1 billion people sustain traumatic injuries, resulting in over 900,000 deaths in Africa and 6 million deaths globally. Timely response, intervention, and transportation in the prehospital setting reduce morbidity and mortality of trauma victims. Our objective was to describe the existing literature evaluating trauma morbidity and mortality outcomes as a function of prehospital care time to identify gaps in literature and inform future investigation. MAIN BODY We performed a scoping review of published literature in MEDLINE. Results were limited to English language publications from 2009 to 2020. Included articles reported trauma outcomes and prehospital time. We excluded case reports, reviews, systematic reviews, meta-analyses, comments, editorials, letters, and conference proceedings. In total, 808 articles were identified for title and abstract review. Of those, 96 articles met all inclusion criteria and were fully reviewed. Higher quality studies used data derived from trauma registries. There was a paucity of literature from studies in low- and middle-income countries (LMIC), with only 3 (3%) of articles explicitly including African populations. Mortality was an outcome measure in 93% of articles, predominantly defined as "in-hospital mortality" as opposed to mortality within a specified time frame. Prehospital time was most commonly assessed as crude time from EMS dispatch to arrival at a tertiary trauma center. Few studies evaluated physiologic morbidity outcomes such as multi-organ failure. CONCLUSION The existing literature disproportionately represents high-income settings and most commonly assessed in-hospital mortality as a function of crude prehospital time. Future studies should focus on how specific prehospital intervals impact morbidity outcomes (e.g., organ failure) and mortality at earlier time points (e.g., 3 or 7 days) to better reflect the effect of early prehospital resuscitation and transport. Trauma registries may be a tool to facilitate such research and may promote higher quality investigations in Africa and LMICs.

However, in many locations, ground emergency medical services are dispatched to the scene of an incident first to assess the patient and then call for a helicopter if needed. The time to definitive care therefore includes the helicopter's flight to the scene, flight to the trauma center, and nonflying time. Mission ground time (MGT) includes the time required to get the helicopter airborne, as well as time spent at the scene, packaging and loading the casualty into the aircraft. Estimates of MGT typically vary from 10 to 30 min. The impact of MGT duration on population coverage-the number of residents that could be taken to a trauma center within a set time-is not known. The aim of this study was to compare population coverage for different durations of MGT in a single state. METHODS Coverage was calculated using elliptical coverage areas ("isochrones") based on the location of helicopter bases and Level I and Level II trauma centers. The calculations were performed using Microsoft Excel, assuming a cruising speed of 133 knots (246 km/h), and mapped using arcGIS. The access time threshold was set at 60 min, and we evaluated MGTs of 10, 15, 20, 25, and 30 min. RESULTS MGT has a marked impact on population coverage. The effect is, furthermore, not linear. When considering the state's three Level I trauma centers, decreasing MGT from 30 to 10 min increased population coverage from 61.2% to 84.2%. When also considering Level II centers, decreasing MGT from 30 min to 10 min increased coverage by 20%. CONCLUSIONS Elliptical isochrones, with allowance for MGT, provide realistic estimates of population coverage. MGT significantly impacts the proportion of the population that can be taken to a Level I and/or Level II Trauma Center within a set time. The impact is not linear, reflecting the uneven distribution of the population. Consideration should be given to minimizing MGT to preserve the benefits of aeromedical retrieval.

Association between prehospital time and outcome of trauma patients in 4 Asian countries: A cross-national, multicenter cohort study. PLoS Med 2020; 17:e1003360. [PMID: 33022018 PMCID: PMC7537901 DOI: 10.1371/journal.pmed.1003360] [Citation(s) in RCA: 35] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Accepted: 08/31/2020] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Whether rapid transportation can benefit patients with trauma remains controversial. We determined the association between prehospital time and outcome to explore the concept of the "golden hour" for injured patients. METHODS AND FINDINGS We conducted a retrospective cohort study of trauma patients transported from the scene to hospitals by emergency medical service (EMS) from January 1, 2016, to November 30, 2018, using data from the Pan-Asia Trauma Outcomes Study (PATOS) database. Prehospital time intervals were categorized into response time (RT), scene to hospital time (SH), and total prehospital time (TPT). The outcomes were 30-day mortality and functional status at hospital discharge. Multivariable logistic regression was used to investigate the association of prehospital time and outcomes to adjust for factors including age, sex, mechanism and type of injury, Injury Severity Score (ISS), Revised Trauma Score (RTS), and prehospital interventions. Overall, 24,365 patients from 4 countries (645 patients from Japan, 16,476 patients from Korea, 5,358 patients from Malaysia, and 1,886 patients from Taiwan) were included in the analysis. Among included patients, the median age was 45 years (lower quartile [Q1]-upper quartile [Q3]: 25-62), and 15,498 (63.6%) patients were male. Median (Q1-Q3) RT, SH, and TPT were 20 (Q1-Q3: 12-39), 21 (Q1-Q3: 16-29), and 47 (Q1-Q3: 32-60) minutes, respectively. In all, 280 patients (1.1%) died within 30 days after injury. Prehospital time intervals were not associated with 30-day mortality. The adjusted odds ratios (aORs) per 10 minutes of RT, SH, and TPT were 0.99 (95% CI 0.92-1.06, p = 0.740), 1.08 (95% CI 1.00-1.17, p = 0.065), and 1.03 (95% CI 0.98-1.09, p = 0.236), respectively. However, long prehospital time was detrimental to functional survival. The aORs of RT, SH, and TPT per 10-minute delay were 1.06 (95% CI 1.04-1.08, p < 0.001), 1.05 (95% CI 1.01-1.08, p = 0.007), and 1.06 (95% CI 1.04-1.08, p < 0.001), respectively. The key limitation of our study is the missing data inherent to the retrospective design. Another major limitation is the aggregate nature of the data from different countries and unaccounted confounders such as in-hospital management. CONCLUSIONS Longer prehospital time was not associated with an increased risk of 30-day mortality, but it may be associated with increased risk of poor functional outcomes in injured patients. This finding supports the concept of the "golden hour" for trauma patients during prehospital care in the countries studied.

Abstract
BACKGROUND Although several trauma centers have developed direct to operating room (DOR) trauma resuscitation programs, there is little published data on optimal patient selection, practices, and outcomes. We sought to analyze triage criteria and interventions associated with optimal DOR outcomes and resource utilization. METHODS Retrospective review of all adult DOR resuscitations for a 6-year period was performed. Triage criteria were analyzed individually and grouped into categories: mechanism, physiology, anatomy/injury, or other. The best univariate and multivariate predictors of requiring lifesaving interventions (LSIs) or emergent surgery (ES) were analyzed. Actual and predicted mortality were compared for all patients and for predefined time-sensitive subgroups. RESULTS There were 628 DOR patients (5% of all admissions) identified; the majority were male (79%), penetrating mechanism (70%), severely injured (40% ISS >15), and 17% died. Half of patients required LSI and 23% required ES, with significantly greater need for ES and lower need for LSI after penetrating versus blunt injury (p < 0.01). Although injury mechanism criteria triggered most DOR cases and best predicted need for ES, the physiology and anatomy/injury criteria were associated with greater need for LSI and mortality. Observed mortality was significantly lower than predicted mortality with DOR for several key subgroups. Triage schemes for both ES and LSI could be simplified to four to six independent predictors by regression analysis. CONCLUSION The DOR program identified severely injured trauma patients at increased risk for requiring LSI and/or ES. Different triage variable categories drive the need for ES versus LSI and could be simplified or optimized based on local needs or preferences. Direct to operating room was associated with better than expected survival among specific time-sensitive subgroups. LEVEL OF EVIDENCE Therapeutic/Care Management, Level IV.

Abstract
Background The time from injury to surgery (TIS) is critical in the functional recovery of individuals with traumatic acute subdural hematoma (TASDH). However, only few studies have confirmed such notion. Methods The data of TASDH patients who were surgically treated in Chia-Yi Christian Hospital between January 2008 and December 2015 were collected. The significance of variables, including age, sex, traumatic mechanism, coma scale, midline shift on brain computed tomography (CT) scan, and TIS, in functional recovery was assessed using the student’s t-test, Mann-Whitney U test, chi-square test, univariate and multivariate models, and receiver operating characteristic (ROC) curve. Results A total of 37 patients achieved functional recovery (outcome scale score of 4 or 5) and 33 patients had poor recovery (outcome scale score of 1–3) after at least 1 year of follow-up. No significant difference was observed in terms of age, sex, coma scale score, traumatic mechanism, or midline shift on brain CT scan between the functional and poor recovery groups. TIS was found to be significantly shorter in the functional recovery group than in the poor recovery group (145.5 ± 27.0 vs. 181.9 ± 54.5 min, P-value = 0.002). TIS was a significant factor for functional outcomes in the univariate and multivariate regression models. The analysis of TIS with the ROC curve between these two groups showed that the threshold time for functional recovery in comatose patients and those with TASDH who were surgically treated was 2 h and 57.5 min. Conclusions TIS is an important factor l for the functional recovery of comatose TASDH patients who underwent surgery.

Simulation-based training is associated with lower risk-adjusted mortality in ACS pediatric TQIP centers. J Trauma Acute Care Surg 2020; 87:841-848.

Abstract
BACKGROUND Although use of simulation-based team training for pediatric trauma resuscitation has increased, its impact on patient outcomes has not yet been shown. The purpose of this study was to determine the association between simulation use and patient outcomes. METHODS Trauma centers that participate in the American College of Surgeons (ACS) Pediatric Trauma Quality Improvement Program (TQIP) were surveyed to determine frequency of simulation use in 2014 and 2015. Center-specific clinical data for 2016 and 2017 were abstracted from the ACS TQIP registry (n = 57,916 patients) and linked to survey responses. Center-specific risk-adjusted mortality was estimated using multivariable hierarchical logistic regression and compared across four levels of simulation-based training use: no training, low-volume training, high-volume training, and survey nonresponders (unknown training use). RESULTS Survey response rate was 75% (94/125 centers) with 78% of the responding centers (73/94) reporting simulation use. The average risk-adjusted odds of mortality was lower in centers with a high volume of training compared with centers not using simulation (odds ratio, 0.58; 95% confidence interval, 0.37-0.92). The times required for resuscitation processes, evaluations, and critical procedures (endotracheal intubation, head computed tomography, craniotomy, and surgery for hemorrhage control) were not different between centers based on levels of simulation use. CONCLUSION Risk-adjusted mortality is lower in TQIP-Pediatric centers using simulation-based training, but this improvement in mortality may not be mediated by a reduction in time to critical procedures. Further investigation into alternative mediators of improved mortality associated with simulation use is warranted, including assessment of resuscitation quality, improved communication, enhanced teamwork skills, and decreased errors.

Identifying patients with time-sensitive injuries: Association of mortality with increasing prehospital time. J Trauma Acute Care Surg 2020; 86:1015-1022.

Abstract
BACKGROUND Trauma is a time-sensitive disease. However, recognizing which patients have time-critical injuries in the field is challenging. Many studies failed to identify an association between increasing prehospital time (PHT) and mortality due to evaluation of heterogenous trauma patients, as well as inherent survival bias from missed deaths in patients with long PHT. Our objective was to determine if a subset of existing trauma triage criteria can identify patients in whom mortality is associated with PHT. METHODS Trauma patients 16 years or older transported from the scene in the National Trauma Databank 2007 to 2015 were included. Cubic spline analysis used to identify an inflection where mortality increases to identify a marginal population in which PHT is more likely associated with mortality and exclude biased patients with long PHT. Logistic regression determined the association between mortality and PHT, adjusting for demographics, transport mode, vital signs, operative interventions, and complications. Interaction terms between existing trauma triage criteria and PHT were tested, with model stratification across triage criteria with a significant interaction to determine which criteria identify patients that have increased risk of mortality associated with increasing PHT. RESULTS Mortality risk increased in patients with total PHT of 30 minutes or less, comprising a study population of 517,863 patients. Median total PHT was 26 minutes (interquartile range, 22-28 minutes) with median Injury Severity Score of 9 (interquartile range, 4-14) and 7.4% mortality. Overall, PHT was not associated with mortality (adjusted odd ratio [AOR], 0.984 per 5-minute increase; 95% confidence interval [CI], 0.960-1.009; p = 0.20). Interaction analysis demonstrated increased mortality associated with increasing PHT for patients with systolic blood pressure less than 90 mm Hg (AOR, 1.039; 95% CI, 1.003-1.078, p = 0.04), Glasgow Coma Scale score of 8 or less (AOR, 1.047; 95% CI, 1.018-1.076; p < 0.01), or nonextremity firearm injury (AOR, 1.049; 95% CI, 1.010-1.089; p < 0.01). CONCLUSION Patients with prehospital hypotension, Glasgow Coma Scale score of 8 or less, and nonextremity firearm injury have higher mortality with increasing PHT. These patients may have time-sensitive injuries and benefit from rapid transport to definitive care. LEVEL OF EVIDENCE Prognostic/Epidemiologic III; Therapeutic/Care Management IV.

Abstract
Introduction Pre-hospital enhanced care teams like Helicopter Emergency Medical Services (HEMS) are often dispatched to major trauma patients, including patients with traumatic brain injuries and those with major haemorrhage. For these patients, minimizing the time to definitive care is vital. The aim of this study was to determine whether increased awareness of elapsed on scene time produces a relevant time performance improvement for major trauma patients attended by HEMS, and weather introducing such a timer was feasible and acceptable to clinicians. Methods We performed a prospective cohort study of all single casualty traumatic incidents attended by Air Ambulance Kent Surrey Sussex (AAKSS) between 15 October 2016 and 23 May 2017 to test if introduction of a prompting scene timer within the service resulted in a reduction in pre-hospital scene times. Results The majority of the patients attended were male (74%) and sustained blunt trauma (92%). Overall, median scene time was 25.5 [IQR16.3] minutes before introduction of the scene timer and 23.0 [11.0] minutes after introduction, p = 0.13). Scene times for patients with a GCS < 8 and for patients requiring prehospital anaesthesia were significantly lower after introduction of the timer (28 [IQR 14] vs 25 [1], p = 0.017 and 34 [IQR 13] vs 28 [IQR11] minutes, p = 0.007 respectively). The majority of clinicians felt the timer made them more aware of passing time (91%) but that this had not made a difference to scene time (62%) or their practice (57%). Conclusion Audible scene timers may have the potential to reduce pre-hospital scene time for certain single casualty trauma patients treated by a HEMS team, particularly for those patients needing pre-hospital anaesthesia. Regular use of on-scene timers may improve outcomes by reducing time to definitive care for certain subgroups of trauma patients.

Abstract
Introduction Increased out-of-hospital time is associated with worse outcomes in trauma. Sparse literature exists comparing prehospital scene and transport time management intervals between adult and pediatric trauma patients. National Emergency Medical Services guidelines recommend that trauma scene time be less than 10 minutes. The objective of this study was to examine prehospital time intervals in adult and pediatric trauma patients. Methods We performed a retrospective cohort study of blunt and penetrating trauma patients in a five-county region in North Carolina using prehospital records. We included patients who were transported emergency traffic directly from the scene by ground ambulance to a Level I or Level II trauma center between 2013–2018. We defined pediatric patients as those less than 16 years old. Urbanicity was controlled for using the Centers for Medicare and Medicaid’s Ambulance Fee Schedule. We performed descriptive statistics and linear mixed-effects regression modeling. Results A total of 2179 records met the study criteria, of which 2077 were used in the analysis. Mean scene time was 14.2 minutes (95% confidence interval [CI], 13.9–14.5) and 35.3% (n = 733) of encounters had a scene time of 10 minutes or less. Mean transport time was 17.5 minutes (95% CI, 17.0–17.9). Linear mixed-effects regression revealed that scene times were shorter for pediatric patients (p<0.0001), males (p=0.0016), penetrating injury (p<0.0001), and patients with blunt trauma in rural settings (p=0.005), and that transport times were shorter for males (p = 0.02), non-White patients (p<0.0001), and patients in urban areas (p<0.0001). Conclusion This study population largely missed the 10-minute scene time goal. Demographic and patient factors were associated with scene and transport times. Shorter scene times occurred with pediatric patients, males, and among those with penetrating trauma. Additionally, suffering blunt trauma while in a rural environment was associated with shorter scene time. Males, non-White patients, and patients in urban environments tended to have shorter transport times. Future studies with outcomes data are needed to identify factors that prolong out-of-hospital time and to assess the impact of out-of-hospital time on patient outcomes.

Abstract
OBJECTIVEIn combat and austere environments, evacuation to a location with neurosurgery capability is challenging. A planning target in terms of time to neurosurgery is paramount to inform prepositioning of neurosurgical and transport resources to support a population at risk. This study sought to examine the association of wait time to craniectomy with mortality in patients with severe combat-related brain injury who received decompressive craniectomy.METHODSPatients with combat-related brain injury sustained between 2005 and 2015 who underwent craniectomy at deployed surgical facilities were identified from the Department of Defense Trauma Registry and Joint Trauma System Role 2 Registry. Eligible patients survived transport to a hospital capable of diagnosing the need for craniectomy and performing surgery. Statistical analyses included unadjusted comparisons of postoperative mortality by elapsed time from injury to start of craniectomy, and Cox proportional hazards modeling adjusting for potential confounders. Time from injury to craniectomy was divided into quintiles, and explored in Cox models as a binary variable comparing early versus delayed craniectomy with cutoffs determined by the maximum value of each quintile (quintile 1 vs 2-5, quintiles 1-2 vs 3-5, etc.). Covariates included location of the facility at which the craniectomy was performed (limited-resource role 2 facility vs neurosurgically capable role 3 facility), use of head CT scan, US military status, age, head Abbreviated Injury Scale score, Injury Severity Score, and injury year. To reduce immortal time bias, time from injury to hospital arrival was included as a covariate, entry into the survival analysis cohort was defined as hospital arrival time, and early versus delayed craniectomy was modeled as a time-dependent covariate. Follow-up for survival ended at death, hospital discharge, or hospital day 16, whichever occurred first.RESULTSOf 486 patients identified as having undergone craniectomy, 213 (44%) had complete date/time values. Unadjusted postoperative mortality was 23% for quintile 1 (n = 43, time from injury to start of craniectomy 30-152 minutes); 7% for quintile 2 (n = 42, 154-210 minutes); 7% for quintile 3 (n = 43, 212-320 minutes); 19% for quintile 4 (n = 42, 325-639 minutes); and 14% for quintile 5 (n = 43, 665-3885 minutes). In Cox models adjusted for potential confounders and immortal time bias, postoperative mortality was significantly lower when time to craniectomy was within 5.33 hours of injury (quintiles 1-3) relative to longer delays (quintiles 4-5), with an adjusted hazard ratio of 0.28, 95% CI 0.10-0.76 (p = 0.012).CONCLUSIONSPostoperative mortality was significantly lower when craniectomy was initiated within 5.33 hours of injury. Further research to optimize craniectomy timing and mitigate delays is needed. Functional outcomes should also be evaluated.

Abstract
Background Chronic subdural hematoma (CSDH) is a common neurological condition; surgical evacuation is the mainstay of treatment for symptomatic patients. No clear evidence exists regarding the impact of timing of surgery on outcomes. We investigated factors influencing time to surgery and its impact on outcomes of interest. Methods Patients with CSDH who underwent burr-hole craniostomy were included. This is a subset of data from a prospective observational study conducted in the UK. Logistic mixed modelling was performed to examine the factors influencing time to surgery. The impact of time to surgery on discharge modified Rankin Scale (mRS), complications, recurrence, length of stay and survival was investigated with multivariable logistic regression analysis. Results 656 patients were included. Time to surgery ranged from 0 to 44 days (median 1, IQR 1–3). Older age, more favorable mRS on admission, high preoperative Glasgow Coma Scale score, use of antiplatelet medications, comorbidities and bilateral hematomas were associated with increased time to surgery. Time to surgery showed a significant positive association with length of stay; it was not associated with outcome, complication rate, reoperation rate, or survival on multivariable analysis. There was a trend for patients with time to surgery of ≥7 days to have lower odds of favorable outcome at discharge (p=0.061). Conclusions This study provides evidence that time to surgery does not substantially impact on outcomes following CSDH. However, increasing time to surgery is associated with increasing length of stay. These results should not encourage delaying operations for patients when they are clinically indicated.
