Temporal Delays in the Management of Traumatic Brain Injury: A Comparative Meta-Analysis of Global Literature. World Neurosurg 2024; 188:185-198.e10. [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] [MESH Headings] [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.

Abstract
INTRODUCTION Unstable abdominal trauma patients should be treated with emergent laparotomy. However, few studies have evaluated the association between time to surgery and survival in these patients. We aimed to assess the influence of time to laparotomy on outcomes in blunt and penetrating unstable abdominal trauma patients. METHODS This retrospective study includes patients with abdominal injuries, systolic blood pressure <90mmHg on arrival, admitted in Israel during 2000-2018. Data regarding patients' characteristics, Injury Severity Score (ISS), Glasgow Coma Scale (GCS), time to surgery, length of hospital stay and mortality were collected via The Israeli National Trauma Registry. RESULTS Overall, 69 blunt and 127 penetrating injury patients were included in the study. For blunt and penetrating trauma patients with ISS ≤14, no differences in outcome were found between patients who underwent laparotomy within 60min of admission and those who underwent laparotomy within 60-120min of admission. In patients with blunt trauma, ISS ≥16, and GCS <15, mortality was higher in the immediate laparotomy group (p = 0.004 and 0.049, respectively). CONCLUSIONS In patients with a penetrating injury, no differences in mortality between immediate and expedient laparotomy were demonstrated. In patients with a blunt injury, with ISS ≥16 and GCS <15, mortality was higher among the immediate laparotomy group.

Eur J Trauma Emerg Surg 2024; 50:489-496. [PMID: 37794254 PMCID: PMC11035447 DOI: 10.1007/s00068-023-02371-0] [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: 03/24/2023] [Accepted: 09/12/2023] [Indexed: 10/06/2023]
Abstract
PURPOSE Interventions performed within the first hour after trauma increase survival rates. Literature showed that measuring times can optimize the trauma resuscitation process as time awareness potentially reduces acute care time. This study examined the effect of a digital clock placement on trauma resuscitation times in an academic level-1 trauma center. METHODS A prospective observational pre-post cohort analysis was conducted for six months before and after implementing a visible clock in the trauma resuscitation room, indicating the time passed since starting the in-hospital resuscitation process. Trauma patients (age ≥ 16) presented during weekdays between 9.00 AM and 9.00 PM were included. Time until diagnostics (X-Ray, FAST, or CT scan), time until therapeutic intervention, and total resuscitation time were measured manually with a stopwatch by a researcher in the trauma resuscitation room. Patient characteristics and information regarding trauma- and injury type were collected. Times before and after clock implementation were compared. RESULTS In total, 100 patients were included, 50 patients in each cohort. The median total resuscitation time (including CT scan) was 40.3 min (IQR 23.3) in the cohort without a clock compared to 44.3 (IQR 26.1) minutes in the cohort with a clock. The mean time until the first diagnostic and until the CT scan was 8.3 min (SD 3.1) and 25.5 min (SD 7.1) without a clock compared to 8.6 min (SD 6.5) and 26.6 min (SD 11.5) with a clock. Severely injured patients (Injury Severity Score (ISS) ≥ 16) showed a median resuscitation time in the cohort without a clock (n = 9) of 54.6 min (IQR 50.5) compared to 46.0 min (IQR 21.6) in the cohort with a clock (n = 8). CONCLUSION This study found no significant reduction in trauma resuscitation time after clock placement. Nonetheless, the data represent a heterogeneous population, not excluding specific patient categories for whom literature has shown that a short time is essential, such as severely injured patients, might benefit from the presence of a trauma clock. Future research is recommended into resuscitation times of specific patient categories and practices to investigate time awareness.

Abstract
Introduction Trauma is a major cause of death worldwide, and prehospital care is critical to improve patient outcomes. However, there is controversy surrounding the effectiveness of limiting scene time to 10 min or less in the care of major trauma patients. This study aimed to investigate the association between scene time and mortality in major trauma patients. Methods A retrospective cohort study was conducted on major trauma patients treated by the Thammasat University Hospital Emergency Medical Services (EMS) team from 2020 to 2022. We included traumatic adult patients who had an injury severity score (ISS) of 16 or higher. The primary outcome was 24-h mortality. Multivariable risk regression analysis was used to evaluate the independent effect of scene time on 24-h mortality. Results A total of 104 patients were included, of whom 11.5% died within 24 h. After adjusting for age, systolic blood pressure, Glasgow Coma Scale, and ISS, patients who had a scene time over 10 min showed a significant association with mortality (33.3% vs. 8.7%, P = 0.031). Intravenous fluid administration at the scene showed a trend toward a significant association with mortality. Conclusions This study provides evidence to support the importance of minimizing scene time for major trauma patients. The findings suggest that a balance between timely interventions and adequate resources should be considered to optimize patient outcomes. Further studies to investigate the impact of prehospital interventions on trauma patient outcomes are needed.

Abstract
BACKGROUND An under-developed and fragmented prehospital Emergency Medical Services (EMS) system is a major obstacle to the timely care of emergency patients. Insufficient emphasis on prehospital emergency systems in low- and middle-income countries (LMICs) currently causes a substantial number of avoidable deaths from time-sensitive illnesses, highlighting a critical need for improved prehospital emergency care systems. Therefore, this systematic review aimed to assess the prehospital emergency care services across LMICs. METHODS This systematic review used four electronic databases, namely: PubMed/MEDLINE, CINAHL, EMBASE, and SCOPUS, to search for published reports on prehospital emergency medical care in LMICs. Only peer-reviewed studies published in English language from January 1, 2010 through November 1, 2022 were included in the review. The Newcastle-Ottawa Scale (NOS) and Critical Appraisal Skills Programme (CASP) checklist were used to assess the methodological quality of the included studies. Further, the protocol of this systematic review has been registered on the International Prospective Register of Systematic Reviews (PROSPERO) database (Ref: CRD42022371936) and has been conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS Of the 4,909 identified studies, a total of 87 studies met the inclusion criteria and were therefore included in the review. Prehospital emergency care structure, transport care, prehospital times, health outcomes, quality of information exchange, and patient satisfaction were the most reported outcomes in the considered studies. CONCLUSIONS The prehospital care system in LMICs is fragmented and uncoordinated, lacking trained medical personnel and first responders, inadequate basic materials, and substandard infrastructure.

Abstract
BACKGROUND Timely access to high-level (I/II) trauma centers (HLTCs) is essential to minimize mortality after injury. Over the last 15 years, there has been a proliferation of HLTC nationally. The current study evaluates the impact of additional HLTC on population access and injury mortality. METHODS A geocoded list of HLTC, with year designated, was obtained from the American Trauma Society, and 60-minute travel time polygons were created using OpenStreetMap data. Census block group population centroids, county population centroids, and American Communities Survey data from 2005 and 2020 were integrated. Age-adjusted nonoverdose injury mortality was obtained from CDC Wide-ranging Online Data for Epidemiologic Research and the Robert Wood Johnson Foundation. Geographically weighted regression models were used to identify independent predictors of HLTC access and injury mortality. RESULTS Over the 15-year (2005-2020) study period, the number of HLTC increased by 31.0% (445 to 583), while population access to HLTC increased by 6.9% (77.5-84.4%). Despite this increase, access was unchanged in 83.1% of counties, with a median change in access of 0.0% (interquartile range, 0.0-1.1%). Population-level age-adjusted injury mortality rates increased by 5.39 per 100,000 population during this time (60.72 to 66.11 per 100,000). Geographically weighted regression controlling for population demography and health indicators found higher median income and higher population density to be positively associated with majority (≥50%) HLTC population coverage and negatively associated with county-level nonoverdose mortality. CONCLUSION Over the past 15 years, the number of HLTC increased 31%, while population access to HLTC increased only 6.9%. High-level (I/II) trauma center designation is likely driven by factors other than population need. To optimize efficiency and decrease potential oversupply, the designation process should include population level metrics. Geographic information system methodology can be an effective tool to assess optimal placement. LEVEL OF EVIDENCE Prognostic and Epidemiological; Level IV.

Abstract
Polytrauma is a condition when a patient has sustained multiple injuries, which can lead to disability or death. While the agriculture industry is growing, the number of polytrauma patients in children is increasing as well. It is high-energy traumas when it is important to immediately assess injuries and life-threatening conditions and to start trauma protocols guided treatment. In this article, we present a case of a 17-year-old boy who suffered extensive injuries caused by a straw pellets machine. We discussed the importance of prehospital care, multidisciplinary team involvement, and treatment methods.

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 aim of this review is to provide the reader with a general overview on the rationale for the use of melatonin by military personnel. This is a technique that is being increasingly employed to manage growing psycho-physical loads. In this context, melatonin, a pleotropic and regulatory molecule, has a potential preventive and therapeutic role in maintaining the operational efficiency of military personnel. In battlefield conditions in particular, the time to treatment after an injury is often a major issue since the injured may not have immediate access to medical care. Any drug that would help to stabilize a wounded individual, especially if it can be immediately administered (e.g., per os) and has a very high safety profile over a large range of doses (as melatonin does) would be an important asset to reduce morbidity and mortality. Melatonin may also play a role in the oscillatory synchronization of the neuro-cardio-respiratory systems and, through its epigenetic action, poses the possibility of restoring the main oscillatory waves of the cardiovascular system, such as the Mayer wave and RSA (respiratory sinus arrhythmia), which, in physiological conditions, result in the oscillation of the heartbeat in synchrony with the breath. In the future, this could be a very promising field of investigation.

Abstract
BACKGROUND Motor vehicle collisions remain a leading cause of trauma-related deaths. We aim to investigate the relationship between the proximity of trauma centers to the nearest highway exit and prehospital motor vehicle collision fatalities at the county level nationwide. METHODS This was a cross-sectional study evaluating the association between the distance of trauma centers to the nearest highway exit and prehospital motor vehicle collision fatalities between the years 2014 and 2019. Prehospital motor vehicle collision fatalities were obtained from National Highway Traffic Safety Administration. Mapping software was used to determine the distance of trauma center to the nearest highway exit and transport time. Linear regression analysis was performed. RESULTS A total of 2,019 American College of Surgeons-verified and/or state-designated trauma centers were included (211 Level 1, 356 Level 2, 491 Level 3, and 961 Level 4 trauma centers). Prehospital motor vehicle collision fatalities were positively correlated with the distance of trauma center to the nearest highway exit for counties with trauma centers located ≤5 miles from the nearest highway exit (r = 0.328; P < .001). In the 612 counties with a 10% increase in prehospital motor vehicle collision fatalities from 2014 to 2019, prehospital motor vehicle collision fatalities were also positively correlated with distance to the nearest highway exit (r = 0.302; P < .001). The counties with more dispersed distributions of trauma centers were significantly associated with motor vehicle collision fatalities (Spearman's rank coefficient = 0.456; 95% confidence interval, 0.163-0.675; P = .003). CONCLUSION Shorter distances between trauma centers and the nearest highway exit are associated with fewer prehospital motor vehicle collision fatalities for counties with trauma centers ≤5 miles of the nearest highway exit. Further enhancement of existing highway infrastructure and standardization of emergency medical services transport protocols are needed to address the burden of prehospital motor vehicle collision fatalities in the United States.

Abstract
OBJECTIVE The objective of this study was to identify timing distribution and predictors of deaths following road traffic injuries among all age groups at Gondar Comprehensive specialised hospital. DESIGN A single-centre prospective cohort study. SETTING The study hospital is a tertiary hospital in North West Ethiopia. PARTICIPANTS We enrolled 454 participants who sustained road traffic injuries in to the current study. All age groups and injury severity were included except those who arrived dead, had no attendant and when the injury time was unknown. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome was time to death measured in hours from injury time up to the 30th day of the injuries. Secondary outcomes were prehospital first aid, length of hospital stay and hospital arrival time. The article has been registered, with a unique identification number of research registry 6556. RESULTS A total of 454 victims were followed for 275 534 person hours. There were 80 deaths with an overall incidence of 2.90 deaths per 10 000 person hours of observation (95% CI 2.77 to 3.03). The significant predictors of time to death were being a driver (AHR=2.26; 95% CI 1.09 to 4.65, AR=14.8), accident at interurban roads ((AHR (Adjusted HAzard Ratio=1.98; 95% CI 1.02 to 3.82, AR (Attributable Risk)=21%)), time from injury to hospital arrival (AHR=0.41; 95% CI 0.16 to 0.63; AR=3%), systolic blood pressure on admission of <90 mm Hg (AHR=3.66; 95% CI 2.14 to 6.26; AR=57%), Glasgow Coma Scale of <8 (AHR=7.39; 95% CI 3.0819 to 17.74464; AR=75.7%), head injury with polytrauma (AHR=2.32 (1.12774 4.79; AR=37%) and interaction of distance from hospital with prehospital care. CONCLUSION Though the maturation of trauma centres in many developed countries has changed the temporal pattern of deaths following any trauma, our study demonstrated that trauma deaths follow the traditional trimodal pattern. That implies that potentially preventable causes of death continued in low-resource countries.

Abstract
One of the significant challenges to translation of intravenously administered nanomaterials has been complement-mediated infusion reactions which can be lethal. Slow infusions can reduce infusion reactions, but slow infusions are not always possible in applications like controlling bleeding following trauma. Thus, avoiding complement activation and infusion responses is essential to manage bleeding. We identified nanocapsules based on polyurethane as candidates that did not activate C5a and explored their PEGylation and functionalization with the GRGDS peptide to create a new class of hemostatic nanomaterials. Using the clinically relevant rotational thromboelastography (ROTEM), we determined that nanocapsules promote faster clotting than controls and maintain the maximum clot firmness, which is critical for reducing bleeding. Excitingly, these polyurethane-based nanocapsules did not activate complement or the major pro-inflammatory cytokines. This work provides critical evidence for the role of modulating the core material in developing safer nanomedicines for intravenous applications.

Abstract
Objective: Major trauma is a major concern in public health and a leading cause of mortality worldwide. This study aimed to evaluate the association between the prehospital scene time interval (STI) and survival in emergency medical service (EMS)-assessed major trauma patients admitted to the intensive care unit (ICU). Methods: A retrospective observational study using the Pan-Asian Trauma Outcomes Study (PATOS) database was conducted. Adult trauma patients with injury severity scores (ISSs) greater than 15 who were admitted to the ICU were selected. EMS STIs were categorized into three groups: short (0-8 minutes), intermediate (9-16 minutes), and long (over 16 minutes). The primary outcome was survival to hospital discharge, and the secondary outcome was good neurological outcome at hospital discharge. Multivariable logistic regression analysis was conducted to calculate odds ratios and confidence intervals, adjusting for age, sex, mechanism of injury, prehospital alertness, prehospital shock index, response time interval, and EMS intervention (airway, oxygen supplementation, and intravenous fluid administration). Sensitivity analysis for patients who underwent surgery or nontraumatic brain injury cases and interaction analysis by EMS intervention were performed. Results: Data from a total of 1,874 eligible patients were analyzed. Intermediate and long STIs showed significant associations with outcomes, with adjusted ORs (95% CI) of 1.21 (1.07-1.38) in the intermediate STI group and 1.74 (1.55-1.96) in the long STI group for survival and 1.37 (1.32-1.40) in the intermediate STI group and 1.31 (1.22-1.41) in the long STI group for neurological outcome. In the sensitivity analysis, the highest ORs were found in the intermediate STI group, with adjusted ORs (95% CI) of 1.40 (1.37-1.42) for survival and 1.32 (1.26-1.38) for neurological outcome. In the interaction analysis, EMS intervention showed a positive interaction effect with an intermediate STI on survival. Conclusion: In EMS-assessed adult major trauma patients admitted to the ICU, we found significant associations between STIs longer than 8 minutes and outcomes. EMS intervention has a positive interaction effect with an intermediate STI on survival. More research is needed to understand the implications of practice for major trauma in the field.

Abstract
Resistance to hypoxia is one of the most prominent features of natural hibernation and is expected to be present in the pharmacological torpor (PT) that simulates hibernation. We studied resistance to lethal hypoxia (3.5% oxygen content) in rats under PT. To initiate PT, we used the previously developed pharmacological composition (PC) which, after a single intravenous injection, can induce a daily decrease in Tb by 7 °C-8 °C at the environmental temperature of 22 °C-23 °C. Half-survival (median) time of rats in lethal hypoxia was found to increase from 5 ± 0.8 min in anesthetized control rats to 150 ± 12 min in rats injected with PC, which is a 30-fold increase. Behavioral tests after PT and hypoxia, including the traveling distance, the number of rearing and grooming episodes, revealed that animal responses are significantly restored within a week. It is assumed that the discovered unprecedented resistance of artificially torpid rats to lethal hypoxia may open up broad prospects for the therapeutic use of PT for preconditioning to various damaging factors, treatment of diseases, and extend the so-called "golden hour" for lifesaving interventions.
