Callaghan NI, Quinn J, Liwski R, Chisholm N, Cheng C. Process Mining Uncovers Actionable Patterns of Red Blood Cell Unit Wastage in a Health Care Network. Transfus Med Rev 2024; 38:150827. [PMID: 38642414 DOI: 10.1016/j.tmrv.2024.150827] [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: 10/04/2023] [Revised: 03/17/2024] [Accepted: 03/19/2024] [Indexed: 04/22/2024]
Abstract
Packed red blood cell transfusions are integral to the care of the critically and chronically ill patient, but require careful storage and a large, coordinated network to ensure their integrity during distribution and administration. Auditing a Transfusion Medicine service can be challenging due to the complexity of this network. Process mining is an analytical technique that allows for the identification of high-efficiency pathways through a network, as well as areas of challenge for targeted innovation. Here, we detail a case study of an efficiency audit of the Transfusion Medicine service of the Nova Scotia Health Administration Central Zone using process mining, across a period encompassing years prior to, during, and after the acute COVID-19 pandemic. Service efficiency from a product wastage perspective was consistently demonstrated at benchmarks near globally published optima. Furthermore, we detail key areas of continued challenge in product wastage, and suggest potential strategies for further targeted optimization.

[PMID: 37958036 PMCID: PMC10647734 DOI: 10.3390/healthcare11212892] [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: 09/14/2023] [Revised: 10/20/2023] [Accepted: 10/30/2023] [Indexed: 11/15/2023] Open
Abstract
BACKGROUND Amidst a rising tide of trauma-related emergencies, emergency departments worldwide grapple with the challenges of overcrowding and prolonged patient wait times. Addressing these challenges, the integration of prehospital intensive care units has appeared as a promising solution, streamlining trauma care and enhancing patient safety. Nevertheless, the feasibility of such an initiative becomes murky when considered globally. This review delves into the intricacies of prehospital intensive care units' deployment for trauma care, scrutinizing their configurations, operational practices, and the inherent challenges and research priorities. METHODS A scoping review was performed for eligible studies. The result was uploaded to the RAYYAN research platform, facilitating simultaneous evaluation of the studies by all researchers. RESULTS A total of 42 studies were initially selected. Four studies were duplicates, and 25 studies were unanimously removed as irrelevant. The remaining studies (n = 13) were included in the review, and the outcomes were categorized into diverse subgroups. CONCLUSIONS A country's emergency medical services must achieve specific milestones in education, competency, resource availability, and performance to effectively harness the potential of a prehospital intensive care unit. While certain nations are equipped, others lag, highlighting a global disparity in readiness for such advanced care modalities.

Abstract
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.

Abstract
Introduction: Time is an essential element in outcomes of trauma patients. The relationship of time to treatment in management of noncompressible torso hemorrhage (NCTH) with resuscitative endovascular balloon occlusion of the aorta (REBOA) or resuscitative thoracotomy (RT) has not been previously described. We hypothesized that shorter times to intervention would reduce mortality. Methods: A review of the Aortic Occlusion for Resuscitation in Trauma and Acute Care Surgery registry from 2013 to 2022 was performed to identify patients who underwent emergency department aortic occlusion (AO). Multivariate logistic regression was used to examine the impact of time to treatment on mortality. Results: A total of 1,853 patients (1,245 [67%] RT, 608 [33%] REBOA) were included. Most patients were male (82%) with a median age of 34 years (interquartile range, 30). Median time from injury to admission and admission to successful AO were 31 versus 11 minutes, respectively. Patients who died had shorter median times from injury to successful AO (44 vs. 72 minutes, P < 0.001) and admission to successful AO (10 vs. 22 minutes, P < 0.001). Multivariate logistic regression demonstrated that receiving RT was the strongest predictor of mortality (odds ratio [OR], 6.6; 95% confidence interval [CI], 4.4-9.9; P < 0.001). Time from injury to admission and admission to successful AO were not significant. This finding was consistent in subgroup analysis of RT-only and REBOA-only populations. Conclusions: Despite expedited interventions, time to aortic occlusion did not significantly impact mortality. This may suggest that rapid in-hospital intervention was often insufficient to compensate for severe exsanguination and hypovolemia that had already occurred before emergency department presentation. Selective prehospital advanced resuscitative care closer to the point of injury with "scoop and control" efforts including hemostatic resuscitation warrants special consideration.

Abstract
OBJECTIVE Helicopter emergency medical services are part of many emergency health care systems, ensuring specialized treatment on site. The objective of this study was to develop and validate a protocol for the use of packed red blood cells in advanced support helicopter air medical care in Brazil. METHODS This was a methodological validation study with a quantitative approach developed in 2 stages (ie, protocol development and content validity using the Delphi technique) by 24 judges. For data analysis, the content validity index and Kappa agreement analysis were used. RESULTS The protocol consists of 28 verification items distributed in the following 6 topics: 1) request and transport, 2) packaging, 3) use in air medical service, 4) transfer of the blood transfusion patient, 5) recording, and 6) unused red blood cell concentrate. A kappa value of 0.91 and an overall content validity index of 0.95 and greater than 0.8 on all individual items were obtained. CONCLUSION The protocol proved to be valid regarding the content for the use of packed red blood cells in air medical service. It is an essential resource to guide professionals in assisting patients with class III and IV hemorrhage requiring transfusion in air medical service.

Abstract
The use of pre-hospital blood transfusion by air ambulance crews is increasing. Blood transfusion is traditionally ‘authorised’ by doctors, not prescribed. However, there is an increasing interest in extending the capability of authorisation to other practitioners – that is, non-medical authorisation (NMA). A UK framework for nurses and midwives has existed since 2007, but training for critical care paramedics (CCPs) has been limited. The Resuscitation with Pre-Hospital Blood Products (RePHILL) trial was launched in 2016, requiring pre-hospital administration of red cells and LyoPlas. Authorisation was initially restricted to doctors, leading to missed recruitment by paramedic-only crews. The trial protocol was amended in 2019 to permit NMA following suitable training and stakeholder consultation. We present a targeted training programme designed to support paramedic-led transfusion within the framework of the pre-hospital trial. We considered the knowledge and skills required for NMA and compared this with baseline knowledge from paramedic training to identify the training gap. We examined examples of existing military and civilian NMA training to develop a targeted programme for a single air ambulance. The four elements of our training programme were pre-course online training, previous trial participation, face-to-face training and competency assessment. Training was delivered to three CCPs, who cascaded the training to 14 colleagues. The training time was one morning, including a face-to-face session and assessment. Novel topics included physiological triggers for transfusion and transfusion risks in the pre-hospital environment. Paramedics were encouraged to recognise and report new patterns of adverse events. Reflective feedback suggests the programme provided CCPs the knowledge to autonomously recruit trial patients and authorise transfusion.

Abstract
OBJECTIVES The Tactical Combat Casualty Care (TCCC) guidelines detail resuscitation practices in prehospital and austere environments. We sought to review the content and quality of the current TCCC and civilian prehospital literature and characterize knowledge gaps to offer recommendations for future research. METHODS MEDLINE, EMBASE, CINAHL, and Cochrane Central Register of Controlled Trials were searched for studies assessing intervention techniques and devices used in civilian and military prehospital settings that could be applied to TCCC guidelines. Screening and data extraction were performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Quality appraisal was conducted using appropriate tools. RESULTS Ninety-two percent (n=57) of studies were observational. Most randomized trials had low risk of bias, whereas observational studies had higher risk of bias. Interventions of massive hemorrhage control (n=17) were wound dressings and tourniquets, suggesting effective hemodynamic control. Airway management interventions (n=7) had high success rates with improved outcomes. Interventions of respiratory management (n=12) reported low success with needle decompression. Studies assessing circulation (n=18) had higher quality of evidence and suggested improved outcomes with component hemostatic therapy. Hypothermia prevention interventions (n=2) were generally effective. Other studies identified assessed the use of extended focused assessment with sonography in trauma (n=3) and mixed interventions (n=2). CONCLUSIONS The evidence was largely non-randomized with heterogeneous populations, interventions, and outcomes, precluding robust conclusions in most subjects addressed in the review. Knowledge gaps identified included the use of blood products and concentrate of clotting factors in the prehospital setting. LEVEL OF EVIDENCE Systematic review, level III.

Abstract
AIM In this study, we examine the impact of a trauma-based resuscitation protocol on survival outcomes following emergency medical services (EMS) witnessed traumatic out-of-hospital cardiac arrest (OHCA). METHODS We included EMS-witnessed OHCAs arising from trauma and occurring between 2008 and 2019. In December 2016, a new resuscitation protocol for traumatic OHCA was introduced prioritising the treatment of potentially reversible causes before conventional cardiopulmonary resuscitation. The effect of the new protocol on survival outcomes was assessed using adjusted multivariable logistic regression models. RESULTS Paramedics attempted resuscitation on 490 patients, with 341 (69.6%) and 149 (30.4%) occurring during the control and intervention periods, respectively. A reduction in the proportion of cases receiving cardiopulmonary resuscitation and epinephrine administration were found in the intervention period compared to the control period, whereas trauma-based interventions increased significantly, including blood administration (pre-arrest: 17.9% vs 3.7%; intra-arrest: 24.1% vs 2.7%), splinting (pre-arrest: 38.6% vs 17.1%; intra-arrest: 20.7% vs 5.2%), and finger thoracostomy (pre-arrest: 13.1% vs 0.6%; intra-arrest: 22.8% vs 0.9%), respectively, with p-values < 0.001 for all comparisons. After adjustment, the trauma-based resuscitation protocol was not associated with an improvement in survival to hospital discharge (AOR 1.29, 95% CI: 0.51-3.23), event survival (AOR 0.72, 95% CI: 0.41-1.28) or prehospital return of spontaneous circulation (AOR 0.63, 95% CI: 0.39-1.03). CONCLUSION In our region, the introduction of a trauma-based resuscitation protocol led to an increase in the delivery of almost all trauma interventions; however, this did not translate into better survival outcomes following EMS-witnessed traumatic OHCA.

Abstract
PURPOSE OF REVIEW Posttraumatic bleeding following major trauma is life threatening for the patient and remains a major global health issue. Bleeding after major trauma is worsened by trauma-induced coagulopathy (TIC). TIC consists of acute trauma coagulopathy and resuscitation coagulopathy. The early diagnosis and management of prehospital TIC management are challenging. RECENT FINDINGS Concepts for early diagnosis and management of civilian prehospital TIC management are evolving. The feasibility of prehospital blood component as well as coagulation factor transfusion has been proven. SUMMARY Due to different national guidelines and regulations of blood component therapies there is a wide heterogeneity in concepts of prehospital damage control resuscitation. Tranexamic acid administration is widely accepted, whereas the transfusion of whole blood, blood components, or coagulations factors needs further examination in the civilian setting.

Abstract
AIM In this study, we examine the impact of a trauma-focused resuscitation protocol on survival outcomes following adult traumatic out-of-hospital cardiac arrest (OHCA). METHODS We included adult traumatic OHCA patients aged >16 years occurring between 2008 and 2019. In December 2016, a new resuscitation protocol for traumatic OHCA was introduced prioritising the treatment of potentially reversible causes before conventional cardiopulmonary resuscitation (CPR). The effect of the new protocol on survival outcomes was assessed using adjusted interrupted time series regression. RESULTS Over the study period, paramedics attempted resuscitation on 996 patients out of 3,958 attended cases. Of the treated cases, 672 (67.5%) and 324 (32.5%) occurred during pre-intervention and intervention periods, respectively. The frequency of almost all trauma interventions was significantly higher in the intervention period, including external haemorrhage control (15.7% vs 7.6; p-value <0.001), blood administration (3.8% vs 0.2%; p-value <0.001), and needle thoracostomy (75.9% vs 42.0%; p-value <0.001). There was also a significant reduction in the median time from initial patient contact to the delivery of needle thoracostomy (4.4 min vs 8.7 min; p-value <0.001) and splinting (8.7 min vs 17.5 min; p-value = 0.009). After adjustment, the trauma-focused resuscitation protocol was not associated with a change in the level of survival to hospital discharge (adjusted odds ratio [AOR] 0.98; 95% confidence interval [CI]: 0.11-8.59), event survival (AOR 0.82; 95% CI: 0.33-2.03), or prehospital return of spontaneous circulation (AOR 1.30; 95% CI: 0.61-2.76). CONCLUSION Despite an increase in trauma-based interventions and a reduction in the time to their administration, our study did not find a survival benefit from a trauma-focused resuscitation protocol over initial conventional CPR. However, survival was low with both approaches.

Abstract
AIM We aimed to investigate the impact of temporal changes in the epidemiology and management of traumatic out-of-hospital cardiac arrest (OHCA) on emergency medical service (EMS) attempted resuscitations and survival outcomes. METHODS A retrospective observational study of traumatic OHCA cases involving patients aged > 16 years in Victoria, Australia, who arrested between 2001 and 2018. Unadjusted and adjusted logistic regression was performed to assess trends in survival outcomes over the study period. RESULTS Between 2001 and 2018, the EMS attended 5,631 cases of traumatic OHCA, of which 1,237 cases (22.0%) received an attempted resuscitation. EMS response times increased significantly over time (from 7.0 min in 2001-03 to 9.8 min in 2016-18; p trend < 0.001) as did rates of bystander cardiopulmonary resuscitation (CPR) (from 37.8% to 63.6%; p trend < 0.001). Helicopter EMS attendance on scene increased from 7.1% to 12.4% (p trend = 0.01), and transports of patients with return of spontaneous circulation (ROSC) to designated major trauma centres also increased from 36.6% to 82.4% (p trend < 0.001). The frequency of EMS trauma-specific interventions increased over the study period, including needle thoracostomy from 7.7% to 61.6% (p trend < 0.001). Although the risk-adjusted odds of ROSC (OR 1.06, 95% CI: 1.03-1.10) and event survival (OR 1.05, 95% CI: 1.01-1.09) increased year-on-year, there were no temporal changes in survival to hospital discharge. CONCLUSION Despite higher rates of bystander CPR and EMS trauma interventions, rates of survival following traumatic OHCA did not change over time in our region. More studies are needed to investigate the optimal EMS interventions for improved survival in traumatic OHCA.

Abstract
BACKGROUND Massive infusions of crystalloids into bleeding hypotensive patients can worsen the outcome. Military experience suggests avoiding crystalloids using early damage control resuscitation with blood components in out of hospital setting. Civilian emergency medical services have since followed this idea. We describe our red blood cell protocol in helicopter emergency medical services (HEMS) and initial experience with prehospital blood products from the first 3 years after implementation. METHODS We performed an observational study of patients attended by the HEMS unit between 2015 and 2018 to whom packed red blood cells, freeze-dried plasma, or both were transfused. The Student's two-sided T-test was used to compare vitals in prehospital phase with those at the hospital's emergency department. A p-value < 0.05 was considered significant. RESULTS Altogether, 62 patients received prehospital transfusions. Of those, 48 (77%) were trauma patients and most (n = 39, 81%) suffered blunt trauma. The transfusion began at a median of 33 (IQR 21-47) minutes before hospital arrival. Median systolic blood pressure showed an increase from 90 mmHg (IQR 75-111 mmHg) to 107 mmHg (IQR 80-124 mmHg; P < 0.026) during the prehospital phase. Four units of red blood cells were handled incorrectly when unused red blood cells were returned and required disposal during a three-year period. There were no reported adverse effects from prehospital transfusions. CONCLUSION We treated two patients per month with prehospital blood products. A prehospital physician-staffed HEMS unit carrying blood products is a feasible and safe method to start transfusion roughly 30 min before arrival to the hospital. TRIAL REGISTRATION The study was retrospectively registered by the Tampere University Hospital's Medical Director (R19603) 5.11.2019.

Finger thoracostomy in patients with chest trauma performed by paramedics on a helicopter emergency medical service. Emerg Med Australas 2020; 32:650-656. [PMID: 32564497 DOI: 10.1111/1742-6723.13549] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2019] [Revised: 04/08/2020] [Accepted: 04/27/2020] [Indexed: 01/07/2023]
Abstract
OBJECTIVE To determine the frequency of finger thoracostomy performed by intensive care flight paramedics after the introduction of a training programme in this procedure and complications of the procedure that were diagnosed after hospital arrival. METHODS This was a retrospective cohort study of adult and paediatric trauma patients undergoing finger thoracostomy performed by paramedics on a helicopter emergency medical service between June 2015 and May 2018. Hospital data were obtained through a manual search of the medical records at each of the three receiving major trauma services. Additional data were sourced from the Victorian State Trauma Registry. RESULTS The final analysis included 103 cases, of which 73.8% underwent bilateral procedures with a total of 179 finger thoracostomies performed. The mean age of patients was 42.8 (standard deviation 21.4) years and 73.8% were male. Motor vehicle collision was the most common mechanism of injury accounting for 54.4% of cases. The median Injury Severity Score was 41 (interquartile range 29-54). There were 30 patients who died pre-hospital, with most (n = 25) having finger thoracostomy performed in the setting of a traumatic cardiac arrest. A supine chest X-ray was performed prior to intercostal catheter insertion in 38 of 73 patients arriving at hospital; of these, none demonstrated a tension pneumothorax. There were three cases of potential complications related to the finger thoracostomy. CONCLUSION Finger thoracostomy was frequently performed by intensive care flight paramedics. It was associated with a low rate of major complications and given the deficiencies of needle thoracostomy, should be the preferred approach for chest decompression.

Transfus Med 2020; 30:86-105.

Abstract
OBJECTIVES The primary aim of this scoping review is to describe the current use of pre-hospital transfusion of red blood cells (PHTRBC) and to evaluate criteria used to initiate PHTRBC. The effects on patients' outcomes will be reviewed in Part 2. BACKGROUND Haemorrhage is a preventable cause of death in trauma patients, and transfusion of red blood cells is increasingly used by Emergency Medical Services (EMS) for damage control resuscitation. However, there are no guidelines and little consensus on when to initiate PHTRBC. METHODS PubMed and Web of Science were searched through January 2019; 71 articles were included. RESULTS Transfusion triggers vary widely and involve vital signs, clinical signs of poor tissue perfusion, point of care measurements and pre-hospital ultrasound imaging. In particular, hypotension (most often defined as systolic blood pressure ≤ 90 mmHg), tachycardia (most often defined as heart rate ≥ 120/min), clinical signs of poor perfusion (eg, prolonged capillary refill time or changes in mental status) and injury type (ie, penetrating wounds) are common pre-hospital transfusion triggers. CONCLUSIONS PHTRBC is increasingly used by Emergency Medical Services, but guidelines on when to initiate transfusion are lacking. We identified the most commonly used transfusion criteria, and these findings may provide the basis for consensus-based pre-hospital transfusion protocols.

Abstract
The primary aim of this systematic review is to describe the effects of prehospital transfusion of red blood cells (PHTRBC) on patient outcomes. Damage control resuscitation attempts to prevent death through haemorrhage in trauma patients. In this context, transfusion of red blood cells is increasingly used by emergency medical services (EMS). However, evidence on the effects on outcomes is scarce. PubMed and Web of Science were searched through January 2019; 55 articles were included. No randomised controlled studies were identified. While several observational studies suggest an increased survival after PHTRBC, consistent evidence for beneficial effects of PHTRBC on survival was not found. PHTRBC appears to improve haemodynamic parameters, but there is no evidence that shock on arrival to hospital is averted, nor of an association with trauma induced coagulopathy or with length of stay in hospitals or intensive care units. In conclusion, PHTRBC is increasingly used by EMS, but there is no strong evidence for effects of PHTRBC on mortality. Further research with study designs that allow causal inferences is required for more conclusive evidence. The combination of PHTRBC with plasma, as well as the use of individualised transfusion criteria, may potentially show more benefits and should be thoroughly investigated in the future. The review was registered at Prospero (CRD42018084658).

Abstract
AIM Paediatric traumatic out-of-hospital cardiac arrest (OHCA) is a rare event with few survivors. We examined long-term trends in the incidence and outcomes of paediatric traumatic OHCA and explored the frequency and timing of intra-arrest interventions. METHODS We retrospectively analysed data from the Victorian Ambulance Cardiac Arrest Registry for cases involving traumatic OHCA in patients aged ≤16 years arresting between January 2000 to December 2017. Trends were assessed using linear regression and a non-parametric test for trend. RESULTS A total of 292 cases were attended by emergency medical services (EMS), of which 166 (56.9%) received an attempted resuscitation. The overall incidence of EMS-attended cases was 1.4 cases per 100,000 person-years, with no significant changes over time. Unadjusted outcomes also remained unchanged, with 23.5% achieving return of spontaneous circulation and 3.7% surviving to hospital discharge. The frequency of trauma-specific interventions increased between 2000-2005 and 2012-2017, including needle thoracostomy from 10.5% to 51.0% (p trend <0.001), crystalloid administration from 31.6% to 54.9% (p trend = 0.004) and blood administration from 0.0% to 6.3% (p trend = 0.01). The median time from emergency call to the delivery of interventions were: 12.9 min (IQR: 8.5, 20.0) for cardiopulmonary resuscitation, 19.7 min (IQR: 10.7, 39.6) for external haemorrhage control, 29.8 min (IQR: 22.0, 35.4) for crystalloid administration and 31.5 min (IQR: 21.0, 38.0) for needle thoracostomy. CONCLUSION The incidence and outcomes of paediatric traumatic OHCA remained unchanged over an 18 year period. Early correction of reversible causes by reducing delays to the delivery of trauma-specific interventions may yield additional survivors.

Is prehospital blood transfusion effective and safe in haemorrhagic trauma patients? A systematic review and meta-analysis. Injury 2019; 50:1017-1027. [PMID: 30928164 DOI: 10.1016/j.injury.2019.03.033] [Citation(s) in RCA: 30] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2018] [Revised: 03/06/2019] [Accepted: 03/20/2019] [Indexed: 02/02/2023]
Abstract
BACKGROUND Life-threatening haemorrhage accounts for 40% mortality in trauma patients worldwide. After bleeding control is achieved, circulating volume must be restored. Early in-hospital transfusion of blood components is already proven effective, but the scientific proof for the effectiveness of prehospital blood-component transfusion (PHBT) in trauma patients is still unclear. OBJECTIVE To systematically review the evidence for effectiveness and safety of PHBT to haemorrhagic trauma patients. METHODS CINAHL, Cochrane, EMBASE, and Pubmed were searched in the period from 1988 until August 1, 2018. Meta-analysis was performed for matched trauma patients receiving PHBT with the primary outcomes 24-hour mortality and long-term mortality. Secondary outcome measure was adverse events as a result of PHBT. RESULTS Trauma patients who received PHBT with simultaneous use of packed red blood cells (pRBCs) and plasma showed a statistically significant reduction in long-term mortality (OR = 0.51; 95% CI, 0.36-0.71; P < 0.0001) but no difference in 24-hour mortality (OR = 0.47, 95% CI, 0.17-1.34; P = 0.16). PHBT with individual use of pRBCs showed no difference in long-term mortality (OR = 1.18; 95% CI, 0.93-1.49; P = 0.17) or 24-hour mortality (OR = 0.92; 95% CI, 0.46-1.85; P = 0.82). In a total of 1341 patients who received PHBT, 14 adverse events were reported 1.04%, 95% CI 0.57-1.75%. CONCLUSIONS PHBT with simultaneous use of both pRBCs and plasma resulted in a significant reduction in the odds for long-term mortality. However, based on mainly poor quality evidence no hard conclusion can be drawn about a possible survival benefit for haemorrhagic trauma patients receiving PHBT. Overall, PHBT is safe but results of currently ongoing randomised controlled trials have to be awaited to demonstrate a survival benefit. STUDY TYPE Systematic review and meta-analysis.

Abstract
INTRODUCTION Catastrophic haemorrhage is recognised as the leading cause of preventable death in trauma and is also prevalent in medical and other surgical aetiology. Prehospital blood product transfusion is increasingly available for both military and civilian emergency teams. Hospitals have well-established massive transfusion protocols for the resuscitation of this patient group, however the use and impact in the prehospital field is less understood. AIM To identify and evaluate the current knowledge surrounding prehospital blood product administration for patients with catastrophic haemorrhage. METHODS The integrative review method included systematic searching of online databases Medline, EMBASE, SCOPUS and CINAHL alongside hand-searching for primary research articles published prior to 19 November 2018. Papers were included if the population studied patients with catastrophic haemorrhage who received prehospital transfusion of blood products. The level of evidence and quality was evaluated using the NHMRC hierarchy of evidence. All identified full text articles were reviewed by all authors. RESULTS Twenty-two papers were included in the final analysis, including both civilian (16) and military (6) practice. The earliest publication for prehospital transfusion was 1999, with increasing prevalence in recent years. Findings were extracted and into two main categories; (1) transfusion processes included team staffing, product selection, and criteria for transfusion and (2) transfusion outcomes; transfusion safety, haemoglobin, hospital intervention and mortality. DISCUSSION The level of evidence specific to prehospital blood product transfusion is low, with predominantly retrospective methods and rarely sufficient sample sizes to reach statistical significance. Prehospital research is challenged by clinical and logistical variability preventing accurate cohort matching, sample sizes and inconsistent data collection. Evaluation of prehospital transfusion in isolation is also particularly problematic as multiple factors and developments in clinical practice affect patient outcomes and all samples were subject to survival bias. Conclusion The volume and strength of the available evidence prevents accurate evaluation of the intervention and definitive practice recommendations however prehospital transfusion is shown to be logistically achievable and without serious incident. The reviewed evidence broadly supports the translation of recent in-hospital studies, such as PROMTT and PROPPR. Further research specific to prehospital practice is required to guide the development of evidence-based protocols.

Abstract
A physician-staffed helicopter emergency medical service called a doctor helicopter (DH) in Eastern Shizuoka was equipped with a smartphone video transmission system in April 2018. We herein report on the introduction of this system for the verification of transfusion in the DH. A 51-year-old man visited a local hospital after cutting his left neck himself. He was diagnosed with jugular vein injury and underwent compressive hemostasis. As he entered profound hemorrhagic shock, he underwent tracheal intubation, massive fluid resuscitation, and administration of 3 vasopressor agents to maintain circulation. The Eastern Shizuoka DH was requested to transport this patient. After making contact with the patient, the staff of the DH started prehospital transfusion. Because this was the first case of transfusion in a prehospital setting for our hospital, we held a meeting in which we used a smartphone video transmission system to verify the condition surrounding the transfusion in the DH. By reviewing the video record, we confirmed that the transfusion was performed safely and correctly in the prehospital setting. This smartphone video transmission system was useful for verifying the activity of the staff in the DH.
