Feasibility and diagnostic accuracy of fast whole-body MRI in slightly to moderately injured trauma patients.

OBJECTIVES: To determine the feasibility and diagnostic accuracy of fast whole-body magnetic resonance imaging (WB-MRI) compared to whole-body computed tomography (WB-CT) in detecting injuries of slightly to moderately injured trauma patients. MATERIALS AND METHODS: In a prospective single-center approach, trauma patients from convenience sampling with an expected Abbreviated Injury Scale (AIS) score ≤ 3 at admission, received an indicated contrast-enhanced WB-CT (reference standard) and a plain WB-MRI (index test) voluntarily up to five days after trauma. Two radiologists, blinded to the WB-CT findings, evaluated the absence or presence of injuries with WB-MRI in four body regions: head, torso, axial skeleton, and upper extremity. Diagnostic accuracy was determined using sensitivity, specificity, positive predictive value, and negative predictive value by body region. RESULTS: Between June 2019 and July 2021, 40 patients were assessed for eligibility of whom 35 (median age (interquartile range): 50 (32.5) years; 26 men) received WB-MRI. Of 140 body regions (35 patients × 4 regions), 31 true positive, 6 false positive, 94 true negative, and 9 false negative findings were documented with WB-MRI. Thus, plain WB-MRI achieved a total sensitivity of 77.5% (95%-confidence interval (CI): (61.6-89.2%)), specificity of 94% (95%-CI: (87.4-97.8%)), and diagnostic accuracy of 89.3% (95%-CI: (82.9-93.9%)). Across the four regions sensitivity and specificity varied: head (66.7%/93.1%), torso (62.5%/96.3%), axial skeleton (91.3%/75%), upper extremity (33.3%/100%). Both radiologists showed substantial agreement on the WB-MRI reading (Cohen's Kappa: 0.66, 95%-CI: (0.51-0.81)). CONCLUSION: Regarding injury detection, WB-MRI is feasible in slightly to moderately injured trauma patients, especially in the axial skeleton. CLINICAL RELEVANCE STATEMENT: Besides offering a radiation-free approach, whole-body MRI detects injuries almost identically to whole-body CT in slightly to moderately injured trauma patients, who comprise a relevant share of all trauma patients. KEY POINTS: Whole-body MRI could offer radiation-free injury detection in slightly to moderately injured trauma patients. Whole-body MRI detected injuries almost identically compared to whole-body CT in this population. Whole-body MRI could be a radiation-free approach for slightly to moderately injured young trauma patients.

Prevent Acute Chest Syndrome checklist (PACScheck): A quality improvement initiative to reduce acute chest syndrome.

BACKGROUND: Acute chest syndrome (ACS) is a life-threatening complication of sickle cell disease (SCD). The Prevent Acute Chest Syndrome checklist (PACScheck) was created to drive appropriate ordering of opioids, incentive spirometry (IS), intravenous fluids (IVF), evaluation of oxygen desaturation, and bronchodilator use. OBJECTIVES: Decrease the development of ACS by 5% in a hospitalized pediatric SCD population. METHODS: A multidisciplinary team conducted a quality improvement (QI) project between April 2020 and August 2021 on an inpatient pediatric hematology unit. At-risk hospitalizations were patients with SCD who did not have ACS upon hospital admission. PACScheck was implemented and weekly run charts assessed documentation. Process control (p) charts, geometric control (g) charts, and chi-square tests assessed checklist process measures pre- and post-PACScheck. G chart assessed the number of encounters between ACS events. RESULTS: A total of 483 at-risk hospitalizations were identified in the 12 months prior and 363 during the study period. A g chart demonstrated that fewer encounters developed ACS during PACScheck. A p chart demonstrated that IS documentation increased during PACScheck. A run chart of PACScheck documentation demonstrated a median of 100% documentation at least once per hospitalization during the last six months of the intervention. CONCLUSION: Development of ACS can be reduced by implementing a best-practices checklist (PACScheck) on an inpatient pediatric hematology unit with a multidisciplinary team.

Course and predictors of supportive care needs among colorectal cancer survivors with ostomies: a longitudinal study.

PURPOSE: Although there is a growing emphasis on supportive care for cancer patients, those with colorectal cancer (CRC) who have ostomies require special attention in terms of their physical, psychological, spiritual, and social needs. However, there has been a lack of significant progress in meeting the supportive care needs of CRC survivors with ostomies. To bridge this gap, we conducted a prospective longitudinal study to track the trends in supportive care needs among CRC survivors with ostomies and identify any predictors over 6-month period. METHODS: A prospective longitudinal study was conducted at the wound and stoma clinic of Dalian University Affiliated Xinhua Hospital, focusing on CRC survivors with ostomies. A total of 143 participants completed self-report questionnaires on the 34-item Short-Form Supportive Care Needs Survey (SCNS-SF34-C (Mandarin)) and stoma complications at the first, third, and sixth month after surgery. ANOVA with repeated measure was utilized to assess the course of supportive care needs, with Generalized Estimating Equation (GEE) applied to identify predictors of SCNS. RESULTS: The supportive care needs and five dimensions scores were statistically significant at three time points (P < 0.05). The ratings of patients at the first, third, and sixth month after surgery revealed a decreasing trend in the scores for patient care and support, psychological needs, physical and daily living needs, and health system and information needs. However, the score for sexual needs showed an increased tendency. Higher levels supportive care needs were generally connected with a short duration after ostomy, high income level, resident medical insurance, spouse caregiver, other chronic disease, and stoma complications. CONCLUSIONS: Survivors' supportive care needs showed a dynamic trend over 6 months after surgery. Through three rounds, the primary needs were health system and information needs. It is recommended to integrate interdisciplinary health professionals and establish a comprehensive support and care system to effectively meet the diverse needs at different stages. Priority should be given to individuals with ostomies during the first and third month after surgery, particularly those with higher income levels, employee medical insurance, spouse caregivers, other chronic diseases, and stoma complications.

Delayed Withdrawal of Life-Sustaining Treatment in Disorders of Consciousness: Practical and Theoretical Considerations.

Disorders of consciousness (DoC) resulting from severe acute brain injuries may prompt clinicians and surrogate decision makers to consider withdrawal of life-sustaining treatment (WLST) if the neurologic prognosis is poor. Recent guidelines suggest, however, that clinicians should avoid definitively concluding a poor prognosis prior to 28 days post injury, as patients may demonstrate neurologic recovery outside the acute time period. This practice may increase the frequency with which clinicians consider the option of delayed WLST (D-WLST), namely, WLST that would occur after hospital discharge, if the patient's recovery trajectory ultimately proves inconsistent with an acceptable quality of life. However acute care clinicians are often uncertain about what D-WLST entails and therefore find it difficult to properly counsel surrogates about this option. Here, we describe practical and theoretical considerations relevant to D-WLST. We first identify post-acute-care facilities to which patients with DoC are likely to be discharged and where D-WLST may be considered. Second, we describe how clinicians and surrogates may determine the appropriate timing of D-WLST. Third, we outline how D-WLST is practically implemented. And finally, we discuss psychosocial barriers to D-WLST, including the regret paradox, in which surrogates of patients who do not recover to meet preestablished goals frequently choose not to ultimately pursue D-WLST. Together, these practical, logistic, and psychosocial factors must be considered when potentially deferring WLST to the post-acute-care setting to optimize neurologic recovery for patients, avoid prolonged undue suffering, and promote informed and shared decision-making between clinicians and surrogates.

Development and validation of assessment instruments for cervical collar and spinal board placement in simulated environments for nursing students in the care of polytrauma patients.

BACKGROUND: Multiple trauma injuries are the leading cause of death and disability in people under the age of 45 and require prompt and specialised care. However, medical and nursing education programmes do not always include specific training in emergency pre-hospital care, resulting in a lack of basic practical skills in trauma management. OBJECTIVE: To develop and validate two instruments for assessing nursing students' competence in cervical collar and spinal board application in simulated pre-hospital emergency scenarios. METHOD: This is an instrumental study that involves the development of two assessment instruments and the evaluation of their psychometric properties in a sample of 392 nursing students. Content validity was assessed using expert judgement, by calculating the content validity ratio (CVR) for each item and the scale level content validity index average (S-CVI/Ave) for the instruments. Exploratory factor analysis using the MINRES extraction method and Promax rotation was performed to analyse the performance of the items and structure of the rubrics. Internal consistency was analysed using the Omega coefficient and inter-rater agreement was assessed using Cohen's Kappa coefficient. RESULTS: Initially, two rubrics were obtained: one with six items for cervical collar placement (S-CVI/Ave = 0.86) and one with nine items for spinal board placement (S-CVI/Ave = 0.81). Both had a single-factor structure, with all items having factor loadings greater than 0.34 for the cervical collar rubric and 0.56 for the spinal board rubric, except for item 2 of the cervical collar rubric (λ = 0.24), which was subsequently removed. The final cervical collar rubric (five items) had an overall internal consistency of 0.84 and the spinal board rubric had an overall internal consistency of 0.90, calculated using the Omega statistic. The weighted Kappa coefficient for each item ranged from acceptable (0.32) to substantial (0.79). These results show that we have successfully developed two sufficiently valid instruments to assess the immobilisation competencies proposed in the objective of the study. CONCLUSION: Whilst further research is needed to fully establish their psychometric properties, these instruments offer a valuable starting point for evaluating nursing students' competence in cervical collar and spinal board application in simulated pre-hospital scenarios.

Changes in temperature in preheated crystalloids at ambient temperatures relevant to a prehospital setting: an experimental simulation study with the application of prehospital treatment of trauma patients suffering from accidental hypothermia.

BACKGROUND: Accidental hypothermia is common in all trauma patients and contributes to the lethal diamond, increasing both morbidity and mortality. In hypotensive shock, fluid resuscitation is recommended using fluids with a temperature of 37-42°, as fluid temperature can decrease the patient's body temperature. In Sweden, virtually all prehospital services use preheated fluids. The aim of the present study was to investigate how the temperature of preheated infusion fluids is affected by the ambient temperatures and flow rates relevant for prehospital emergency care. METHODS: In this experimental simulation study, temperature changes in crystalloids preheated to 39 °C were evaluated. The fluid temperature changes were measured both in the infusion bag and at the patient end of the infusion system. Measurements were conducted in conditions relevant to prehospital emergency care, with ambient temperatures varying between - 4 and 28 °C and flow rates of 1000 ml/h and 6000 ml/h, through an uninsulated infusion set at a length of 175 cm. RESULTS: The flow rate and ambient temperature affected the temperature in the infusion fluid both in the infusion bag and at the patient end of the system. A lower ambient temperature and lower flow rate were both associated with a greater temperature loss in the infusion fluid. CONCLUSION: This study shows that both a high infusion rate and a high ambient temperature are needed if an infusion fluid preheated to 39 °C is to remain above 37 °C when it reaches the patient using a 175-cm-long uninsulated infusion set. It is apparent that the lower the ambient temperature, the higher the flow rate needs to be to limit temperature loss of the fluid.

Primary care doctors in acute call-outs to severe trauma incidents in Norway - variations by rural-urban settings and time factors.

BACKGROUND: A severely injured patient needs fast transportation to a hospital that can provide definitive care. In Norway, approximately 20% of the population live in rural areas. Primary care doctors (PCDs) play an important role in prehospital trauma care. The aim of this study was to investigate how variations in PCD call-outs to severe trauma incidents in Norway were associated with rural-urban settings and time factors. METHODS: In this study on severe trauma patients admitted to Norwegian hospitals from 2012 to 2018, we linked data from four official Norwegian registries. Through this, we investigated the call-out responses of PCDs to severe trauma incidents. In multivariable log-binomial regression models, we investigated whether factors related to rural-urban settings and time factors were associated with PCD call-outs. RESULTS: There was a significantly higher probability of PCD call-outs to severe trauma incidents in the municipalities in the four most rural centrality categories compared to the most urban category. The largest difference in adjusted relative risk (95% confidence interval (CI)) was 2.08 (1.27-3.41) for centrality category four. PCDs had a significantly higher proportion of call-outs in the Western (RR = 1.46 (1.23-1.73)) and Central Norway (RR = 1.30 (1.08-1.58)) Regional Health Authority areas compared to in the South-Eastern area. We observed a large variation (0.47 to 4.71) in call-out rates to severe trauma incidents per 100,000 inhabitants per year across the 16 Emergency Medical Communication Centre areas in Norway. CONCLUSIONS: Centrality affects the proportion of PCD call-outs to severe trauma incidents, and call-out rates were higher in rural than in urban areas. We found no significant difference in call-out rates according to time factors. Possible consequences of these findings should be further investigated.

Mobile blood depots in ground ambulances in compliance with French legislation: A feasibility study.

BACKGROUND: Prehospital transfusion is a way of improving the management of hemorrhagic shock. In France, prehospital transfusion is struggling to develop, both because of logistical difficulties and particularly restrictive legislation. To comply with this, we propose to store the blood products (BPs) in ground ambulances with refrigerated boxes allowing remote continuous monitoring of storage conditions, called "NelumBox" (Tec4med Lifescience GmbH). To open them, the ambulance's team needs a code that is only given by the Transfusion Center if the request meets all required regulatory criteria. STUDY DESIGN AND METHODS: We conducted a prospective simulation-based feasibility study using dummy BPs. Two ambulances were equipped. Simulations were triggered unexpectedly, including during on-call hours. The ability to quickly access the BPs was the main judgment criterion. The quality of hemovigilance during these simulations was also examined. RESULTS: Twenty-two simulations were performed. The ambulance's team was able to access the BPs in 100% of cases. The average waiting time for receiving the unlocking code was 5 min 27 s (SD = 2 min 12 s, MAX = 12 min 00 s). The transfusion traceability was compliant with regulations in 100% of cases. The transfusion center was able to remotely monitor BPs storage conditions for the entire duration of their stockage in the NelumBox. DISCUSSION: The present procedure is efficient, repeatable, and fast. It guarantees a strict transfusion safety without slowdown a severe trauma management, while complying with French regulations.

A randomized controlled trial to examine the effect of the Pediatric Opioid Analgesia Self-Instruction System (PedOASIS) tool on pediatric hematology/oncology trainee education.

BACKGROUND: Many children with hematologic and oncologic diagnoses require opioids for management of pain, yet knowledge gaps persist among pediatric hematology/oncology (PHO) fellows. OBJECTIVE: Pediatric Opioid Analgesia Self-Instruction System (PedOASIS) is an interactive, case-based education tool designed for independent learning. The goal of this study was to evaluate its efficacy in increasing PHO fellows' knowledge and comfort with using opioids to manage pain. DESIGN/METHOD: PHO fellows were recruited from 74 American College of Graduate Medical Education-accredited US programs during the 2019-2020 academic year and randomized to receive access to PedOASIS (intervention) or usual PHO training (control). Surveys at baseline, immediately after accessing the tool, and 6 months later assessed knowledge and comfort related to prescribing opioids. RESULTS: A total of 64 PHO fellows completed the study, with 32 in the intervention group and 32 controls. At baseline, mean scores on the 10-question knowledge assessment were similar between groups (intervention: 5, control: 6; p = .8). Following intervention, mean score was significantly higher in the intervention group (9) versus controls (5; p < .0001). Six months later, scores in both groups decreased but remained significantly higher in the intervention group (7) compared to controls (5, p < .0001) and compared to baseline (p = .0002). Fellows in the intervention group reported significant increases in comfort dosing opioids after exposure to the tool (p = .02). CONCLUSION: PHO fellows exposed to the tool had improved scores on validated knowledge questions and greater comfort using opioids for pain management compared to controls. We therefore suggest that PedOASIS warrants further evaluation as a potential tool for PHO fellows.

Comparison of healthcare utilization and life-sustaining interventions between patients with glioblastoma receiving palliative care or not: A population-based study.

BACKGROUND: Palliative care has historically been under-utilized in patients with glioblastoma. Furthermore, literature on the utilization of healthcare and life-sustaining interventions during the late-stage of glioblastoma has been limited. AIM: To identify and compare healthcare utilization and life-sustaining interventions between patients with glioblastoma who received palliative care and who did not based on patients identified retrospectively from Taiwan Cancer Registry between January 2007 and December 2017. DESIGN: In this study, palliative care was defined on the basis of claims submitted to the National Health Insurance, which has a specific code for it. Variables included demographic characteristics, the utilization of healthcare services, and invasive life-sustaining interventions. SETTING/PARTICIPANTS: Of the 1994 patients with glioblastoma identified, 1784 fulfilled the inclusion criteria, 613 (34%) of whom received palliative care. RESULTS: The survival of patients with glioblastoma under palliative care was significantly longer than that of those without palliative care. Those without palliative care had significantly more frequent intensive care unit admissions and a longer cumulative length of intensive care unit stay. Regarding cardiopulmonary or respiratory treatments, patients without palliative care had significantly more invasive interventions than those with palliative care. Patients receiving palliative care had significantly lower odds than those without life-sustaining interventions. CONCLUSIONS: Our retrospective analysis reveals that glioblastoma patients without palliative care had greater odds of receiving life-sustaining treatments within 1 year before their death, although no gains in survival as compared to those that received palliative care. These findings highlight the urgent need for palliative care in caring for patients with glioblastoma.

Autoresuscitation after circulatory arrest: an updated systematic review.

PURPOSE: Current practice in organ donation after death determination by circulatory criteria (DCD) advises a five-minute observation period following circulatory arrest, monitoring for unassisted resumption of spontaneous circulation (i.e., autoresuscitation). In light of newer data, the objective of this updated systematic review was to determine whether a five-minute observation time was still adequate for death determination by circulatory criteria. SOURCE: We searched four electronic databases from inception to 28 August 2021, for studies evaluating or describing autoresuscitation events after circulatory arrest. Citation screening and data abstraction were conducted independently and in duplicate. We assessed certainty in evidence using the GRADE framework. PRINCIPAL FINDINGS: Eighteen new studies on autoresuscitation were identified, consisting of 14 case reports and four observational studies. Most studies evaluated adults (n = 15, 83%) and patients with unsuccessful resuscitation following cardiac arrest (n = 11, 61%). Overall, autoresuscitation was reported to occur between one and 20 min after circulatory arrest. Among all eligible studies identified by our reviews (n = 73), seven observational studies were identified. In observational studies of controlled withdrawal of life-sustaining measures with or without DCD (n = 6), 19 autoresuscitation events were reported in 1,049 patients (incidence 1.8%; 95% confidence interval, 1.1 to 2.8). All resumptions occurred within five minutes of circulatory arrest and all patients with autoresuscitation died. CONCLUSION: A five-minute observation time is sufficient for controlled DCD (moderate certainty). An observation time greater than five minutes may be needed for uncontrolled DCD (low certainty). The findings of this systematic review will be incorporated into a Canadian guideline on death determination. STUDY REGISTRATION: PROSPERO (CRD42021257827); registered 9 July 2021.

RéSUMé: OBJECTIF: La pratique actuelle en matière de don d'organes après une détermination du décès par critères circulatoires (DCC) préconise une période d'observation de cinq minutes après l'arrêt circulatoire et le monitorage de la reprise non assistée de la circulation spontanée (c.-à-d. l'auto-réanimation). À la lumière de données plus récentes, l'objectif de cette revue systématique mise à jour était de déterminer si un temps d'observation de cinq minutes était toujours suffisant pour une détermination de décès selon des critères circulatoires (DCC). SOURCES: Nous avons effectué des recherches dans quatre bases de données électroniques depuis leur création jusqu'au 28 août 2021 pour en tirer les études évaluant ou décrivant des événements d'autoréanimation après un arrêt circulatoire. L'examen des citations et l'extraction des données ont été réalisés de manière indépendante et en double. Nous avons évalué la certitude des données probantes à l'aide de la méthodologie GRADE. CONSTATATIONS PRINCIPALES: Dix-huit nouvelles études sur l'autoréanimation ont été identifiées, comprenant 14 présentations de cas et quatre études observationnelles. La plupart des études ont évalué des adultes (n = 15, 83 %) et les patients dont la réanimation avait échoué à la suite d'un arrêt cardiaque (n = 11, 61 %). Dans l'ensemble, l'autoréanimation a été signalée entre une et 20 minutes après l'arrêt circulatoire. Parmi toutes les études admissibles identifiées par nos comptes rendus (n = 73), sept études observationnelles ont été identifiées. Dans les études observationnelles sur l'interruption contrôlée des thérapies de maintien des fonctions vitales avec ou sans DCC (n = 6), 19 événements d'autoréanimation ont été rapportés chez 1049 patients (incidence 1,8 % ; intervalle de confiance à 95 %, 1,1 à 2,8). Toutes les reprises ont eu lieu dans les cinq minutes suivant l'arrêt circulatoire et tous les patients en autoréanimation sont décédés. CONCLUSION: Un temps d'observation de cinq minutes est suffisant pour un DCC contrôlé (certitude modérée). Un temps d'observation supérieur à cinq minutes peut être nécessaire en cas de DDC non contrôlé (faible certitude). Les résultats de cette revue systématique seront intégrés à des lignes directrices canadienne de pratique clinique sur la détermination du décès. ENREGISTREMENT DE L'éTUDE: PROSPERO (CRD42021257827); enregistrée le 9 juillet 2021.

Effects of life-sustaining treatment plans on healthcare expenditure and healthcare utilization.

PURPOSE: To develop an ethical and cultural infrastructure for Life-Sustaining Treatment (LST) plan, it is crucial to carefully analyze its impact and ensure that healthcare utilization is maintained at an appropriate level, avoiding excessive medical interventions. This study aims to investigate the effects of LST decisions on both healthcare expenditure and utilization. METHODS: This cohort study utilized claims data from the National Health Insurance Service, encompassing all medical claims in South Korea. We included individuals who had planned to withdraw or withhold their LST between January and December 2018, identified by claim code IA71, IA72, IA73. We followed a total of 28,295 participants with documented LST plan who were deceased by June 2020. Participants were categorized into LST withdrawal / withholding and LST continuation groups. The dependent variables were healthcare expenditure and utilization. We construct a generalized linear model to analyze the association between these variables. RESULTS: Out of the 28,295 participants, 24,436 (86.4%) chose to withdraw or withhold LST, while the rest opted for its continuation. Compared to the LST continuation group, those who chose to withdraw or withhold LST had 0.91 times lower odds for total cost. Additionally, they experienced 0.91 times fewer hospitalization days and 0.92 times fewer outpatient visits than those in the LST continuation group. CONCLUSION: Healthcare expenditure and utilization deceased among those choosing to withdraw or withhold LST compared to those continuing it. These findings underscore the significance of patients actively participating in decision regarding their treatment to ensure appropriate levels of medical intervention for LST. Furthermore, they emphasize the critical role of proper education and the establishment of a cultural framework for LST plans.

"I can't make all this work." End of life care provision in natural disasters: a qualitative study.

BACKGROUND: Natural disasters are becoming more frequent and severe and profoundly impact the end-of-life care experience, including service provision. There is a paucity of research examining healthcare workers' experiences in responding to care demands when disasters strike. This research aimed to fill this gap by exploring end-of-life care providers' perceptions of the impact of natural disasters on end-of-life care. METHODS: Between Feb 2021-June 2021 ten in-depth semi-structured interviews were conducted with healthcare professionals providing end-of-life care during recent natural disasters, COVID-19, and/or fires and floods. Interviews were audio-recorded, transcribed, and analysed using a hybrid inductive and deductive thematic approach. RESULTS: The overarching theme from the healthcare workers' accounts was of being unable to provide effective compassionate and quality care - "I can't make all this work." They spoke of the considerable burdens the system imposed on them, of being overextended and overwhelmed, having their roles overturned, and losing the human element of care for those at end-of-life. CONCLUSION: There is urgent need to pioneer effective solutions to minimise the distress of healthcare professionals in delivering end-of-life care in disaster contexts, and to improve the experience of those dying.

Can a Therapeutic Strategy for Hypotension Improve Cerebral Perfusion and Oxygenation in an Experimental Model of Hemorrhagic Shock and Severe Traumatic Brain Injury?

BACKGROUND: Restoration of brain tissue perfusion is a determining factor in the neurological evolution of patients with traumatic brain injury (TBI) and hemorrhagic shock (HS). In a porcine model of HS without neurological damage, it was observed that the use of fluids or vasoactive drugs was effective in restoring brain perfusion; however, only terlipressin promoted restoration of cerebral oxygenation and lower expression of edema and apoptosis markers. It is unclear whether the use of vasopressor drugs is effective and beneficial during situations of TBI. The objective of this study is to compare the effects of resuscitation with saline solution and terlipressin on cerebral perfusion and oxygenation in a model of TBI and HS. METHODS: Thirty-two pigs weighing 20-30 kg were randomly allocated into four groups: control (no treatment), saline (60 ml/kg of 0.9% NaCl), terlipressin (2 mg of terlipressin), and saline plus terlipressin (20 ml/kg of 0.9% NaCl + 2 mg of terlipressin). Brain injury was induced by lateral fluid percussion, and HS was induced through pressure-controlled bleeding, aiming at a mean arterial pressure (MAP) of 40 mmHg. After 30 min of circulatory shock, resuscitation strategies were initiated according to the group. The systemic and cerebral hemodynamic and oxygenation parameters, lactate levels, and hemoglobin levels were evaluated. The data were subjected to analysis of variance for repeated measures. The significance level established for statistical analysis was p < 0.05. RESULTS: The terlipressin and saline plus terlipressin groups showed an increase in MAP that lasted until the end of the experiment (p < 0.05). There was a notable increase in intracranial pressure in all groups after starting treatment for shock. Cerebral perfusion pressure and cerebral oximetry showed no improvement after hemodynamic recovery in any group. The groups that received saline at resuscitation had the lowest hemoglobin concentrations after treatment. CONCLUSIONS: The treatment of hypotension in HS with saline and/or terlipressin cannot restore cerebral perfusion or oxygenation in experimental models of HS and severe TBI. Elevated MAP raises intracranial pressure owing to brain autoregulation dysfunction caused by TBI.

The effect of population density on outcomes of major trauma patients in Ireland.

BACKGROUND: Time-sensitive emergencies in areas of low population density have statistically poorer outcomes. This includes incidents of major trauma. This study assesses the effect that population density at a receiving hospital of a major trauma patient has on survival. METHODS: Patients meeting Trauma Audit Research Network criteria for major trauma from 2016 to 2020 in Ireland were included in this retrospective observational study. Incident data were retrieved from the Major Trauma Audit, while data on population density were calculated from Irish state sources. The primary outcome measure of survival to discharge was compared to population density using logistic regression, adjusted for demographic and incident variables. Records were divided into population density tertiles to assess for between-group differences in potential predictor variables. RESULTS: Population density at a receiving hospital had no impact on mortality in Irish major trauma patients from our logistic regression model (OR = 1.01, 95% CI 0.98-1.05, p = 0.53). Factors that did have an impact were age, Charlson Comorbidity Index, Injury Severity Score, and the presence of an Orthopaedic Surgery service at the receiving hospital (all p < 0.001). Age and Charlson Comorbidity Index differed slightly by population density tertile; both were higher in areas of high population density (all p < 0.001). CONCLUSIONS: Survival to discharge in Irish major trauma patients does not differ substantially based on population density. This is an important finding as Ireland moves to a new trauma system, with features based on population distribution. An Orthopaedic Surgery service is an important feature of a major trauma receiving hospital and its presence improves outcomes.

Potential to enhance telephone cardiopulmonary resuscitation with improved instructions - findings from a simulation-based manikin study with lay rescuers.

BACKGROUND: Telephone-Cardiopulmonary Resuscitation (T-CPR) significantly increases rate of bystander resuscitation and improves patient outcomes after out-of-hospital cardiac arrest (OHCA). Nevertheless, securing correct execution of instructions remains a difficulty. ERC Guidelines 2021 recommend standardised instructions with continuous evaluation. Yet, there are no explicit recommendations on a standardised wording of T-CPR in the German language. We investigated, whether a modified wording regarding check for breathing in a German T-CPR protocol improved performance of T-CPR. METHODS: A simulation study with 48 OHCA scenarios was conducted. In a non-randomised trial study lay rescuers were instructed using the real-life-CPR protocol of the regional dispatch centre and as the intervention a modified T-CPR protocol, including specific check for breathing (head tilt-chin lift instructions). Resuscitation parameters were assessed with a manikin and video recordings. RESULTS: Check for breathing was performed by 64.3% (n = 14) of the lay rescuers with original wording and by 92.6% (n = 27) in the group with modified wording (p = 0.035). In the original wording group the head tilt-chin manoeuvre was executed by 0.0% of the lay rescuers compared to 70.3% in the group with modified wording (p < 0.001). The average duration of check for breathing was 1 ± 1 s in the original wording group and 4 ± 2 s in the group with modified wording (p < 0.001). Other instructions (e.g. check for consciousness and removal of clothing) were well performed and did not differ significantly between groups. Quality of chest compression did not differ significantly between groups, with the exception of mean chest compression depth, which was slightly deeper in the modified wording group. CONCLUSION: Correct check for breathing seems to be a problem for lay rescuers, which can be decreased by describing the assessment in more detail. Hence, T-CPR protocols should provide standardised explicit instructions on how to perform airway assessment. Each protocol should be evaluated for practicability.

Quality assessment in initial paediatric trauma care: Systematic review from prehospital care to the paediatric intensive care unit.

BACKGROUND: Trauma is the most common cause of death and disability in the paediatric population. There are a huge number of variables involved in the care they receive from health care professionals. AIM: The aim of this study was to review the available evidence of initial paediatric trauma care throughout the health care process with a view to create quality indicators (QIs). STUDY DESIGN: A systematic review was performed from Cochrane Library, Medline, Scopus and SciELO between 2010 and 2020. Studies and guidelines that examined quality or suggested QI were included. Indicators were classified by health care setting, Donabedian's model, risk of bias and the quality of the publication with the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) assessment. RESULTS: The initial search included 686 articles, which were reduced to 22, with 15 primary and 7 secondary research articles. The snowball sampling technique was used to add a further seven guidelines and two articles. From these, 534 possible indicators were extracted, summarizing them into 39 and grouping the prehospital care indicators as structure (N = 5), process (N = 12) and outcome (N = 3) indicators and the hospital care indicators as structure (N = 4), process (N = 10) and outcome (N = 6) indicators. Most of the QIs have been extracted from US studies. They are multidisciplinary and in some cases are based on an adaptation of the QIs of adult trauma care. CONCLUSIONS: There was a clear gap and large variability between the indicators, as well as low-quality evidence. Future studies will validate indicators using the Delphi method. RELEVANCE TO CLINICAL PRACTICE: Design a QI framework that may be used by the health system throughout the process. Indicators framework will get nurses, to assess the quality of health care, detect deficient areas and implement improvement measures.

Changes in body mass index during treatment of childhood acute lymphoblastic leukemia with the Nordic ALL2008 protocol.

OBJECTIVES: Children with acute lymphoblastic leukemia (ALL) have a tendency to gain weight during treatment. As overweight and obesity associate with health problems, prophylactic interventions are warranted. Therefore, it is important to identify the children most prone to gain weight. METHODS: Patients aged 2.0-17.9 years at ALL diagnosis were identified from the NOPHO ALL2008 registry. Registry data was complemented with height and weight at the end of therapy from questionnaires. Body mass index (BMI) was classified according to international age- and sex-adjusted International Obesity Task Force BMI cut-offs. BMI values were transformed into standard deviation scores (SDS) to calculate the difference in BMISDS during treatment. RESULTS: Data on BMI change were available for 765 children. Overweight and obesity doubled during treatment: 9.7% were overweight and 2.1% obese at diagnosis and 21.8% and 5.4% at the end of therapy, respectively. The mean BMISDS change was +0.64. Younger (2.0-5.9 years) and healthy weight children were most prone to become overweight (mean change in BMI SDS +0.85 and + 0.65, respectively). CONCLUSIONS: Younger children (2.0-5.9 years) with healthy weight at diagnosis were most prone to becoming overweight and therefore are an important group to target while considering interventions.

Global Neuroblastoma Network: An international multidisciplinary neuroblastoma tumor board for resource-limited countries.

BACKGROUND: Tumor boards are part of standard care of patients with complex cancers, but appropriate multidisciplinary expertise and infrastructure are often not available in low- and middle-income countries (LMIC) for pediatric cancers, such as neuroblastoma. Our goal was to review results of a Global Neuroblastoma Network (GNN) tumor board accessible to LMIC. METHODS: De-identified clinical cases presented via internet conference during a weekly GNN virtual tumor board from 2010 through 2020 were evaluated in a standardized format, including diagnostic imaging, pathology, therapy information, resource limitations, and questions for discussion. Information summarized included the presentations, a survey of the impact on care, and a resource questionnaire. RESULTS: Registered GNN participants included 575 individuals from 77 countries, with a median of 39 participants per session. Total 412 cases were presented from 32 countries, including 351 unique neuroblastoma patients, 52 follow-up cases, and nine non-neuroblastoma diagnoses. Twenty-eight educational sessions were presented. Limited critical resources for diagnostics and staging of cases included MYCN analysis (54.7%), metaiodobenzylguanidine (MIBG) scans (38.7%), and International Neuroblastoma Pathology Classification (49%). Therapies were also limited, with markedly decreased use of radiation and autologous stem cell transplant for high-risk cases, and no availability of anti-GD2 antibody in LMIC. Limited sampling with a post-presentation survey showed that 100% found the GNN helpful, and 70% altered the care plan based on the discussion. CONCLUSION: This report shows the utility of an international tumor board for LMIC focused on a challenging solid tumor where local expertise may be limited, with international multidisciplinary expert participation and educational sessions.

A qualitative examination of the benefits and challenges of a psychosocial screening intervention in pediatric oncology: "Support comes to us".

BACKGROUND: Pediatric cancer diagnosis and treatment can have detrimental mental health effects on parents (caregivers) and their children/adolescents (youth). Psychosocial screening and intervention have been recognized as standards of care in pediatric oncology. The most effective psychosocial interventions to support those in need post screening have not been determined. AIMS: This qualitative study aimed to investigate the perceived benefits and challenges for caregiver and youth participants in the screening-intervention arm of an Enhanced Psychosocial Screening Intervention (EPSI) pilot study. METHODS: EPSI consists of a psychosocial navigator (PSN) who shares screening results conducted near diagnosis (T1) and monthly for 1 year (T2) with treating teams and families. All 17 caregiver-youth dyads who had completed EPSI were invited to participate in a semi-structured interview. RESULTS: Ten caregivers and nine youth participated. Identified themes were grouped into benefits and challenges of EPSI: feeling supported and cared for (support comes to us regularly, having someone to talk to); and feeling empowered through knowledge of resources and services were perceived as benefits. Caregivers were challenged by feeling overwhelmed, and youth by screening questions perceived as too repetitive. CONCLUSIONS: Regular monthly contacts for a year by the PSN with screening results and recommendations were perceived as beneficial by youth newly diagnosed with cancer and their caregivers who participated in EPSI. Feeling that support came to them and they had someone to talk to was a critical component. While information about psychosocial resources was not always used right away, it did evoke feelings of being empowered.
