Follow-up after major traumatic injury: a survey of services in Australian and New Zealand public hospitals.

BACKGROUND: Increased survival from traumatic injury has led to a higher demand for follow-up care when patients are discharged from hospital. It is currently unclear how follow-up care following major trauma is provided to patients, and how, when, and to whom follow-up services are delivered. The aim of this study was to describe the current follow-up care provided to patients and their families who have experienced major traumatic injury in Australia and New Zealand (ANZ). METHODS: Informed by Donabedian's 'Evaluating the Quality of Medical Care' model and the Institute of Medicine's Six Domains of Healthcare Quality, a cross-sectional online survey was developed in conjunction with trauma experts. Their responses informed the final survey which was distributed to key personnel in 71 hospitals in Australia and New Zealand that (i) delivered trauma care to patients, (ii) provided data to the Australasian Trauma Registry, or (iii) were a Trauma Centre. RESULTS: Data were received from 38/71 (53.5%) hospitals. Most were Level 1 trauma centres (n = 23, 60.5%); 76% (n = 16) follow-up services were permanently funded. Follow-up services were led by a range of health professionals with over 60% (n = 19) identifying as trauma specialists. Patient inclusion criteria varied; only one service allowed self-referral (3.3%). Follow-up was within two weeks of acute care discharge in 53% (n = 16) of services. Care activities focused on physical health; psychosocial assessments were the least common. Most services provided care for adults and paediatric trauma (60.5%, n = 23); no service incorporated follow-up for family members. Evaluation of follow-up care was largely as part of a health service initiative; only three sites stated evaluation was specific to trauma follow-up. CONCLUSION: Follow-up care is provided by trauma specialists and predominantly focuses on the physical health of the patients affected by major traumatic injury. Variations exist in terms of patient selection, reason for follow-up and care activities delivered with gaps in the provision of psychosocial and family health services identified. Currently, evaluation of trauma follow-up care is limited, indicating a need for further development to ensure that the care delivered is safe, effective and beneficial to patients, families and healthcare organisations.

A novel method to quantify fibrin-fibrin and fibrin-α2-antiplasmin cross-links in thrombi formed from human trauma patient plasma.

BACKGROUND: The widespread use of the antifibrinolytic agent, tranexamic acid (TXA), interferes with the quantification of fibrinolysis by dynamic laboratory assays such as clot lysis, making it difficult to measure fibrinolysis in many trauma patients. At the final stage of coagulation, factor (F)XIIIa catalyzes the formation of fibrin-fibrin and fibrin-α2-antiplasmin (α2AP) cross-links, which increases clot mechanical strength and resistance to fibrinolysis. OBJECTIVES: Here, we developed a method to quantify fibrin-fibrin and fibrin-α2AP cross-links that avoids the challenges posed by TXA in determining fibrinolytic resistance in conventional assays. METHODS: Fibrinogen alpha (FGA) chain (FGA-FGA), fibrinogen gamma (FGG) chain (FGG-FGG), and FGA-α2AP cross-links were quantified using liquid chromatography-mass spectrometry (LC-MS) and parallel reaction monitoring in paired plasma samples from trauma patients prefibrinogen and postfibrinogen replacement. Differences in the abundance of cross-links in trauma patients receiving cryoprecipitate (cryo) or fibrinogen concentrate (Fg-C) were analyzed. RESULTS: The abundance of cross-links was significantly increased in trauma patients postcryo, but not Fg-C transfusion (P < .0001). The abundance of cross-links was positively correlated with the toughness of individual fibrin fibers, the peak thrombin concentration, and FXIII antigen (P < .05). CONCLUSION: We have developed a novel method that allows us to quantify fibrin cross-links in trauma patients who have received TXA, providing an indirect measure of fibrinolytic resistance. Using this novel approach, we have avoided the effect of TXA and shown that cryo increases fibrin-fibrin and fibrin-α2AP cross-linking when compared with Fg-C, highlighting the importance of FXIII in clot formation and stability in trauma patients.

Rotational thromboelastometry values across age groups in all trauma patients presenting to a level 1 trauma centre: An observational study.

OBJECTIVES: To describe rotational thromboelastometry (ROTEM) values (FIBTEM A5, EXTEM A5 and EXTEM CT) across age groups and assess for a statistical trend; and to determine whether any trend in ROTEM values is affected by severity of injury and packed red blood cells (PRBC) requirement. METHODS: Retrospective observational study at a level 1 trauma centre in Queensland, Australia. A total of 1601 consecutive trauma patients presenting to the ED. ROTEM data described included FIBTEM A5, EXTEM A5 and EXTEM CT. These values are described by age group (≤30 years, 31-45 years, 46-60 years, 61-75 years and >75 years), Injury Severity Score (ISS) category (<12, ≥12, <25 and ≥25) and number of PRBCs transfused in the first 24 h of admission (0 units, 1-4 units, 5-9 units and ≥10 units). RESULTS: The median age of participants was 37 years (interquartile range [IQR] 25-54 years), with 48.2% of patients had severe trauma (ISS >12) and 13.2% receiving at least one unit of PRBC in the first 24 h of admission. Median (IQR) values for FIBTEM A5, EXTEM A5 and EXTEM CT were 13 mm (10-16 mm), 45 mm (40-49 mm) and 62 s (56-71 s), respectively. A test for trend over progressive age groups showed an increase in FIBTEM A5 (P < 0.001) and EXTEM A5 values (P < 0.001) and a decrease in EXTEM CT values (P < 0.001). CONCLUSION: The present study demonstrated a pattern of increasing coagulability, as defined by ROTEM, with increasing age group in trauma patients, even among the severely injured. Further investigation is required to determine the clinical impact of these findings on both the ROTEM-guided management and longitudinal outcomes of these patients and whether an age-specific approach is beneficial.

Implementing and sustaining Point of Care ROTEM® into a trauma activation protocol for the management of patients with traumatic injury: A mixed-methods study.

BACKGROUND: Up to 40% of patients with traumatic injury experience critical bleeding, many requiring transfusion of blood products. International transfusion guidelines recommend the use of viscoelastic testing to guide blood product replacement. We implemented a Point of Care ROTEM® blood test for trauma patients who present and initiate a trauma activation. OBJECTIVES: The aim of this study was to undertake an evaluation of the implementation data to identify factors which helped and hindered this new practice. METHODS: A sequential mixed-methods design was conducted to evaluate intervention implementation. The intervention was designed with interprofessional collaboration and incorporated education and skills training supplemented with a decision aide. Patients aged ≥ 18 years who met the trauma activation criteria were included. Data collection occurred throughout the 21-month implementation period inclusive of initial roll out, maintenance and sustainability and include the number of ROTEM® blood tests taken and clinical characteristics of patients. Individual interviews were conducted with health professionals with experience of the intervention after the implementation period was complete. RESULTS: A total of 1570 eligible patients were included. The number of patients who had a ROTEM® blood test taken increased over time to 63%. The proportion of patients having a ROTEM® blood test obtained was higher for major trauma patients (n=162, 66.9%) who were admitted to the Intensive Care Unit. Regression analysis found trauma service presence on arrival and the sustainability phase of implementation increased the likelihood of having a ROTEM® taken. Qualitative data suggest that a more tailored approach to intervention implementation would assist with adoption. CONCLUSION: Implementation of new practice requires careful planning and should be undertaken with input from end-users. Continuous evaluation is necessary to support ongoing implementation and sustainability. To ensure effective implementation occurs, complex interventions need to be made workable and integrated in everyday health care practice.

Cryoprecipitate transfusion in trauma patients attenuates hyperfibrinolysis and restores normal clot structure and stability: Results from a laboratory sub-study of the FEISTY trial.

BACKGROUND: Fibrinogen is the first coagulation protein to reach critical levels during traumatic haemorrhage. This laboratory study compares paired plasma samples pre- and post-fibrinogen replacement from the Fibrinogen Early In Severe Trauma studY (FEISTY; NCT02745041). FEISTY is the first randomised controlled trial to compare the time to administration of cryoprecipitate (cryo) and fibrinogen concentrate (Fg-C; Riastap) in trauma patients. This study will determine differences in clot strength and fibrinolytic stability within individuals and between treatment arms. METHODS: Clot lysis, plasmin generation, atomic force microscopy and confocal microscopy were utilised to investigate clot strength and structure in FEISTY patient plasma. RESULTS: Fibrinogen concentration was significantly increased post-transfusion in both groups. The rate of plasmin generation was reduced 1.5-fold post-transfusion of cryo but remained unchanged with Fg-C transfusion. Plasminogen activator inhibitor 1 activity and antigen levels and Factor XIII antigen were increased post-treatment with cryo, but not Fg-C. Confocal microscopy analysis of fibrin clots revealed that cryo transfusion restored fibrin structure similar to those observed in control clots. In contrast, clots remained porous with stunted fibres after infusion with Fg-C. Cryo but not Fg-C treatment increased individual fibre toughness and stiffness. CONCLUSIONS: In summary, our data indicate that cryo transfusion restores key fibrinolytic regulators and limits plasmin generation to form stronger clots in an ex vivo laboratory study. This is the first study to investigate differences in clot stability and structure between cryo and Fg-C and demonstrates that the additional factors in cryo allow formation of a stronger and more stable clot.

Fibrinogen Early In Severe paediatric Trauma studY (FEISTY junior): protocol for a randomised controlled trial.

INTRODUCTION: Trauma causes 40% of child deaths in high-income countries, with haemorrhage being a leading contributor to death in this population. There is a growing recognition that fibrinogen and platelets play a major role in trauma-induced coagulopathy (TIC) but the exact physiological mechanisms are poorly understood. METHODS AND ANALYSIS: This is a prospective multicentre, open-label, randomised, two-arm parallel feasibility study conducted in the emergency departments, intensive care units and operating theatres of participating hospitals. Severely injured children, aged between 3 months and 18 years, presenting with traumatic haemorrhage requiring transfusion of blood products will be screened for inclusion.Sixty-eight patients will be recruited and will be allocated to fibrinogen replacement using fibrinogen concentrate (FC) or cryoprecipitate in a 1:1 ratio. Fibrinogen replacement will be administered to patients with a FIBTEM A5 of ≤10. All other aspects of the currently used rotational thromboelastometry-guided treatment algorithm and damage-control approach to trauma remain the same in both groups.The primary outcome is time to administration of fibrinogen replacement from time of identification of hypofibrinogenaemia. Clinical secondary outcomes and feasibility outcomes will also be analysed. ETHICS AND DISSEMINATION: This study has received ethical clearance from the Children's Health Queensland Human Research Ethics Committee (HREC/17/QRCH/78). Equipment and consumables for sample testing have been provided to the study by Haemoview Diagnostics, Werfen Australia and Haemonetics Australia. FC has been provided by CSL Behring, Australia. The funding bodies and industry partners have had no input into the design of the study, and will not be involved in the preparation or submission of the manuscript for publication.The use of viscoelastic haemostatic assays and early fibrinogen replacement has the potential to improve outcomes in paediatric trauma through earlier recognition of TIC. This in turn may reduce transfusion volumes and downstream complications and reduce the reliance on donor blood products such as cryoprecipitate.The use of FC has implications for regional and remote centres who would not routinely have access to cryoprecipitate but could store FC easily. Access to early fibrinogen replacement in these centres could make a significant impact and assist in closing the gap in trauma care available to residents of these communities.Outcomes of this study will be submitted for publication in peer-reviewed journals and submitted for presentation at national and international scientific fora. TRIAL REGISTRATION NUMBER: NCT03508141.

Follow-up of severely injured patients can be embedded in routine hospital care: results from a feasibility study.

OBJECTIVE: Understanding the longitudinal patient experience outcomes following major trauma can promote successful recovery. A novel, hospital-led telephone follow-up program was implemented by a multi-disciplinary clinical trauma service team at a Level I trauma center. This process evaluation examined what factors promoted or impeded the program's implementation. METHODS: A prospective convergent mixed-methods process evaluation design was used. Quantitative data included patient and injury demographics and program feasibility data such number of telephone calls attempted/completed and call duration. Qualitative data consisted of semi-structured interviews with program participants (staff, patients, and caregivers) who had participated in the program. Descriptive statistics and thematic analysis were applied to quantitative and qualitative data, respectively. Data were collected concurrently and merged in the results to understand and describe the implementation and sustainability of the program.274 major trauma patients (ISS ≥ 12) were eligible for follow-up. A response rate of over 75% was achieved, with nurses responsible for most of the calls. Limited time and competing clinical demands were identified as barriers to the timely completion of the calls. RESULTS: Participants valued the preexisting trauma service/patient relationship, and this facilitated program implementation. Clinicians were motivated to evaluate their patient's recovery, whilst patients felt 'cared for' and 'not forgotten' post-hospital discharge. Teamwork and leadership were highly valued by the clinical staff throughout the implementation period as ongoing source of motivation and support.Staff spontaneously developed the program to incorporate clinical follow-up processes by providing guidance, advice, and referrals to patients who indicated ongoing issues such as pain or emotional problems. CONCLUSION: Telephone follow-up within a clinical trauma service team is feasible, accepted by staff and valued by patients and families. Despite time constraints, the successful implementation of this program is reliant on existing clinical/patient relationships, staff teamwork and leadership support.

Rotational thromboelastometry in children presenting to an Australian major trauma centre: A retrospective cohort study.

OBJECTIVE: This retrospective cohort study aims to describe patterns of rotational thromboelastometry (ROTEM™) results in paediatric trauma following the implementation of a ROTEM-guided critical bleeding algorithm and major haemorrhage protocol (MHP). METHODS: This retrospective observational study was conducted in a tertiary trauma hospital in Queensland, Australia, where point-of-care ROTEM was introduced for paediatric patients in 2014. All children aged less than 18 years who had a ROTEM test during their presentation between January 2014 and December 2017 for a traumatic injury were included in the dataset. Other children with a record in the hospital's trauma registry in the same period were also screened for blood product usage. Data were collected for frequency of ROTEM testing, pathology and ROTEM results, blood product and antifibrinolytic use along with injury related data. Compliance with recommended treatment thresholds for detected coagulopathy was also reviewed. RESULTS: A total of 1039 children were listed in the trauma registry, including 167 children having a ROTEM test for trauma. Factors significantly associated with having a ROTEM test were older age, higher injury severity score (ISS >12) and penetrating injury. A result exceeding a treatment threshold was returned for 122 (73.1%) of 167 children, with hyperfibrinolysis identified in 88 (52.6%) of 167 and hypofibrinogenaemia identified in 54 (32.3%) of 167. Adherence with the recommended treatments for those children where a treatment threshold was exceeded was low in this cohort. CONCLUSION: The use of ROTEM-guided blood component replacement is an emerging practice in children for both traumatic and non-traumatic bleeding. Targeted replacement of identified coagulation defects guided by rapid point-of-care testing is an emerging alternative to fixed-ratio-based protocols. Further research is required to validate treatment thresholds in the paediatric population and further investigate the clinical outcomes for patients as a result of early correction of trauma-induced coagulopathy.

Telehealth in trauma: A scoping review.

BACKGROUND: The purpose of this scoping review was to ascertain how 'telehealth' is utilised within health care, from pre hospital to admission, discharge and post discharge, with patients who have suffered major trauma. METHODS: A scoping review of the literature published in English since 1980 was conducted using MEDLINE, Ovid EMBASE, PsychINFO, CINAHL, Austhealth, Cochrane Central Register of Controlled Trials (CENTRAL; Cochrane library) and Web of Science MEDLINE and MEBASE to identify relevant studies. RESULTS: We included 77 eligible studies with both randomised controlled trial and cohort design methodology. A variety of trauma was included such as traumatic brain injuries (n = 52; 67.5%), spinal cord injury (n = 14; 18.2%) and multi-trauma (n = 9; 11.7%) to both adult (n = 38) and paediatric (n = 32) participants. Telehealth is used in pre-hospital and acute-care settings (n = 11; 14.3%) to facilitate assessment, and in rehabilitation and follow-up (n = 61; 79.2%) to deliver therapy. Effects on health were reported the most (n = 46), with no negative outcomes. The feasibility of telehealth as a delivery mode was established, but coordination and technical issues are barriers to use. Overall, both patients and clinicians were satisfied using this mode of delivery. CONCLUSION: This review demonstrates how telehealth is utilised across a spectrum of patients with traumatic injuries and to facilitate delivery of therapy, specialist consultations and assessments, with many studies reporting improvements to health. There is a paucity of high-quality rigorous research, which makes replication of findings and uptake of the intervention problematic. Future telehealth and trauma research should focus on the quality and reproducibility of telehealth interventions and the economic feasibility of using this platform to deliver trauma care.

Substitution of ROTEM FIBTEM A5 for A10 in trauma: an observational study building a case for more rapid analysis of coagulopathy.

PURPOSE: Rotational thromboelastometry (ROTEM®) allows guided blood product resuscitation to correct trauma-induced coagulopathy in bleeding trauma patients. FIBTEM amplitude at 10 min (A10) has been widely used to identify hypofibrinogenaemia; locally a threshold of < 11 mm has guided fibrinogen replacement. Amplitude at 5 min (A5) carries an inherent time advantage. The primary aim was to explore the relationship between FIBTEM A5 and A10 in a trauma. Secondary aim was to investigate the use of A5 as a surrogate for A10 within a fibrinogen-replacement algorithm. METHODS: Retrospective observational cohort study of arrival ROTEM results from 1539 consecutive trauma patients at a Level 1 trauma centre in Australia. Consistency of agreement between FIBTEM A5 and A10 was assessed. A new fibrinogen replacement threshold was developed for A5 using the A5-A10 bias; this was clinically compared to the existing A10 threshold. RESULTS: FIBTEM A5 displayed excellent consistency of agreement with A10. Intraclass correlation coefficient = 0.972 (95% confidence interval [CI] 0.969-0.974). Bias of A5 to A10 was - 1.49 (95% CI 1.43-1.56) mm. 19.34% patients met the original local threshold of A10 < 11 mm; 19.28% patients met the new, bias-adjusted threshold of A5 < 10 mm. CONCLUSION: ROTEM FIBTEM A5 reliably predicts A10 in trauma. This further validates use of the A5 result over A10 allowing faster decision-making in time-critical resuscitation of trauma patients. A modification of -1 to the A10 threshold might be appropriate for use with the A5 value in trauma patients.

Scoping review of the literature to ascertain how follow-up care is provided to major trauma patients post discharge from acute care.

OBJECTIVES: Survival following traumatic injury has increased, requiring ongoing patient follow-up. While longitudinal outcomes of trauma patients are reported, little is known about optimal delivery of follow-up service for this group. The aim of this scoping review was to identify and describe the structure, process and outcomes of postdischarge follow-up services for patients who sustained major trauma. EVIDENCE REVIEW: This scoping review was conducted by searching CINAHL, MEDLINE and EMBASE databases. Articles were screened by three independent reviewers. The data of selected articles were organised in the categories of the Donabedian quality framework: structure, processes and outcomes. RESULTS: Twenty-six articles were included after screening by title/abstract then full text against the inclusion/exclusion criteria; 92% (n=24) were from the USA.Follow-up services were provided by designated trauma centres and delivered by a mixture of health disciplines. Delivery of follow-up was multimodal (in person/telehealth). Protocols and guidelines helped to deliver follow-up care for non-physician led services.Ongoing health issues including missed injuries, pain and infection were identified. No standardised criteria were established to determine recipients, the timing or frequency of follow-up was identified. Patients who engaged with follow-up services were more likely to participate in other health services. Patients reported satisfaction with follow-up care. CONCLUSION: There are wide variations in how follow-up services for major trauma patients are provided. Further evaluation should focus on patient, family and organisational outcomes. Identifying who is most likely to benefit, when and how follow-up care is delivered are important next steps in improving outcomes.

Three-dimensional volume-rendered computed tomography application for follow-up fracture healing and volume measurements pre-surgical rib fixation and post-surgical rib fixation.

BACKGROUND: Surgical rib fixation (SRF) is being used increasingly in trauma centers for stabilization of chest wall injuries, in line with new and evolving surgical techniques. Our institution has developed a pathway for the management of chest wall injuries and SRF, which includes a follow-up low-volume, noncontrast computed tomography (CT) scan at 12 months. METHODS: This study was a single-center retrospective study conducted on 25 consecutive patients who underwent SRF between February 2019 and February 2020. All CT measurements were done by a CT radiographer under the supervision of a board-certified radiologist and included the use of three-dimensional volume-rendered images. RESULTS: There were no patients with SRF who experienced hardware failure at 12 months in either flail or nonflail groups. For fractured ribs treated with SRF, complete or partial union occurred in 75 of 76 ribs plated (98.7%). The median ratio for improvement in lung volumes was 1.71 for flail SRF and 1.69 for nonflail SRF in our study. CONCLUSION: Three-dimensional volume-rendered CT at 12 months post-SRF showed good alignment (no hardware failure) and fracture healing of fixed ribs in both flail and nonflail groups. Lung volumes also improved pre-SRF and post-SRF for both flail and nonflail patients. More studies are needed to define how the pattern of rib fracture healing of fixed and nonfixed ribs affects lung volumes. LEVEL OF EVIDENCE: Therapeutic, Level V.

Outcomes of rib fractures in the geriatric population: A 5-year retrospective, single-institution, Australian study.

BACKGROUND: Surgical rib fixation in the general population can decrease morbidity, including length of stay and ventilator days. Elderly rib fractures convey high rates of morbidity and mortality, and it is unclear whether this population benefits from operative management. METHODS: A single-centre, retrospective study at a Level 1 Australasian trauma centre was conducted. Registry-identified patients aged ≥70 years, admitted to hospital with blunt trauma-induced rib fractures, were included. Outcome measures included demographics, pre-morbid function, acute length of stay, intensive care unit admission, injury characteristics, management and complications. RESULTS: A total of 920 presentations were identified, with 295 meeting the inclusion criteria. Falls accounted for majority (n = 148/295, 50.2%), with a median Injury Severity Score of 10 (inter-quartile range [IQR] 10-14). Severe chest trauma occurred overall in 80% (n = 243/294) and all operative patients (n = 15/15). Conservative management was used in 95% (n = 280/295). Patient-controlled analgesia was common (n = 177/295, 60.0%) and regional techniques increased in the surgical approach (n = 12/15, 80.0%) compared with conservative approach (n = 71/280, 25.4%). Despite longer acute length of stay (12 days, IQR 9-15), operative management resulted in similar complications (26.7% vs. 30.4%) and no deaths. Operative intervention was significantly associated with increased number of fractures (p < 0.001), flail segment (p = 0.001) and higher chest Abbreviated Injury Score (p < 0.001); however, it was not significantly associated with age (p = 0.90), comorbidities (0.91) or anticoagulation (p = 0.51). CONCLUSION: Surgical management of rib fractures in the elderly was performed without increased complications within this centre's multimodal approach. Standard indications for rib fixation may be applicable in the elderly population, whilst comorbidities, age and anticoagulation use alone may not be adequate reasons to withhold surgical rib fixation.

Fibrinogen Early In Severe Trauma studY (FEISTY): results from an Australian multicentre randomised controlled pilot trial.

Background: Haemorrhage is a major cause of death in severe trauma. Fibrinogen plays a critical role in maintaining haemostasis in traumatic haemorrhage, and early replacement using fibrinogen concentrate (FC) or cryoprecipitate (Cryo) is recommended by several international trauma guidelines. Limited evidence supports one product over the other, with widespread geographic and institutional variation in practice. Two previous trials have investigated the feasibility of rapid FC administration in severely injured trauma patients, with conflicting results. Objective: To compare the time to fibrinogen replacement using FC or Cryo in severely injured trauma patients with major haemorrhage and hypofibrinogenaemia. Design, setting, patients and interventions: A multicentre controlled pilot trial in which adult trauma patients with haemorrhage were randomly assigned (1:1) to receive FC or Cryo for fibrinogen replacement, guided by FIBTEM A5 (functional fibrinogen assessment at 5 minutes after clot formation, using rotational thromboelastometry). Main outcome measures: The primary outcome was time to commencement of fibrinogen replacement. Secondary outcomes included effects of the intervention on plasma fibrinogen levels and clinical outcomes including transfusion requirements and mortality. Results: Of the 100 randomly assigned patients, 62 were hypofibrinogenaemic and received the intervention (n = 37) or Cryo (n = 25). Median (interquartile range [IQR]) time to delivery of FC was 29 min (23-40 min) compared with 60 min (40-80 min) for Cryo (P = 0.0001). All 62 patients were hypofibrinogenaemic before receiving FC or Cryo (FC: median FIBTEM A5, 8 mm [IQR, 7-9 mm]; Cryo: median FIBTEM A5, 9 mm [IQR, 5-10 mm]). In the FC arm patients received a median of 3 g FC (IQR, 2-4 g), and in the Cryo arm patients received a median of 8 units of Cryo (IQR, 8-14 units). Restoration of fibrinogen levels was achieved in both arms after the intervention. Blood product transfusion, fluid resuscitation and thromboembolic complications were similar in both arms. Overall mortality was 15.3%, with more deaths in the FC arm. Conclusion: Fibrinogen replacement in severely injured trauma patients with major haemorrhage and hypofibrinogenaemia was achieved substantially faster using FC compared with Cryo. Fibrinogen levels increased appropriately using either product. The optimal method for replacing fibrinogen in traumatic haemorrhage is controversial. Our results will inform the design of a larger trial powered to assess patient-centred outcomes.

Caregiver resilience and patients with severe musculoskeletal traumatic injuries.

AIMS: This study investigated the association of resilience on caregiver burden and quality of life in informal caregivers of patients with severe traumatic musculoskeletal injuries. METHODS: A prospective cohort study of eligible caregivers and acutely injured trauma patients was conducted during 2018 in South East Queensland, with follow-up 3 months after patient discharge. Resilience was examined using the 10-item Connor Davidson Resilience Scale. The primary outcomes, caregiver burden and quality of life were measured respectively, using the Caregiver Strain Index and the Short Form Version 12 Health Survey. RESULTS: Baseline measures were completed with fifty-three (77%) patient/carer dyads. Thirty-eight (28%) were available for follow up at 3 months. Significant reductions from baseline were found at follow up, for levels of resilience, mental health, physical exercise and community support. In multiple regression models, caregiver resilience at follow-up independently predicted lower caregiver burden (ß = -0.74, p = 0.008) and higher levels of patient physical health and function (ß = -0.69, p = 0.003). CONCLUSIONS: Upon commencing informal care, caregivers' resilience, mental health and support systems are adversely affected. Higher levels of caregiver resilience appear to be protective against caregiver burden and declines in patient physical function. Early evaluation of caregivers' resilience, their physical and mental health and socio-ecological networks could improve carer and patient health outcomes.Implications for rehabilitationAfter 3 months of providing informal care to severely injured musculoskeletal trauma patients, there are apparent declines in their mental health, resilience, community support and physical activity levels. However, those with higher levels of resilience compared to lower levels could be protected against caregiver burden. Higher caregiver resilience could also prevent declines in patients' physical function.The rehabilitation of severe trauma patients should additionally include routine assessment and management of informal caregivers with the aim to prevent caregiver burden.Early clinical assessment of caregiver resilience using a valid resilience measurement tool could identify caregivers at risk of caregiver burden and flag vulnerable caregivers for ongoing support in the community.Early assessment of caregivers' physical and mental health and health related behaviours could flag the need for health promotion interventions aimed at supporting caregivers' physical and mental health.

Implementation of point-of-care ROTEM® into a trauma major haemorrhage protocol: A before and after study.

OBJECTIVE: The aim of the present study was to assess transfusion practices with the implementation of a targeted viscoelastic haemostatic assay (VHA) (ROTEM®) guided coagulation management programme into a major haemorrhage protocol for trauma patients requiring ICU admission, starting from time of arrival in the ED. METHODS: This retrospective observational study was conducted in a major trauma centre in Australia. One hundred and sixty-two trauma patients admitted to the ICU between January 2013 and December 2015 with an Injury Severity Score ≥12 and who received blood products were included: 37 in the pre-group, 48 during implementation and 77 in post-group. The primary outcome was blood and blood product administration amounts. RESULTS: Packed red blood cell transfusion amounts did not significantly change post introduction of the ROTEM®. There was a significant increase in fibrinogen replacement between the pre- and post-groups (P < 0.001), accompanied by a reduction in the use of fresh frozen plasma (P < 0.001) and prothrombinex (P < 0.001). Platelet usage in the post-group was higher but not reaching statistical significance (P = 0.051). Post-implementation point-of-care ROTEM® testing was able to be performed in the ED in 94.8% of cases. CONCLUSION: Although there was no overall reduction of packed red blood cell usage, a change in the pattern of administration of other blood products was observed with the implementation of a targeted VHA (ROTEM®) guided coagulation management programme. Larger studies are needed to further define the role of early VHA testing to guide correction of trauma-induced coagulopathy and the effect on clinical outcomes.

Evaluation of a Trauma Service: Patient and Family Perspectives.

BACKGROUND: Patient satisfaction is an indicator of the quality of care that underpins a patient's health care experience. A focus on both the patient and the family is important when evaluating satisfaction from the perspective of patients with trauma and is consistent with delivery of patient- and family-centered care. Using the literature to guide development, we designed and implemented a questionnaire to evaluate attitudes and experiences of patients and families case managed by the trauma service. This article reports the findings of this quality improvement project. METHODS: A cross-sectional cohort pragmatic design was used. The questionnaire was conducted with 142 trauma patients and 49 family members. Data included hospital admission data, application of a satisfaction tool, and free text comments. RESULTS: Both patients and their family members rated the trauma service highly in the satisfaction scoring. Differences in the communication practices encountered by patients and families were identified. CONCLUSIONS: Strategies to involve family members and promote family-centered care are required in the context of trauma patients to improve the safety, quality, and satisfaction of the care they receive while being managed by the trauma service.

Targeted cryoprecipitate transfusion in severe traumatic haemorrhage.

BACKGROUND: Severe traumatic haemorrhage is the leading cause of death in young adults. Trauma Induced Coagulopathy is a complex and multifactorial phenomenon associated with severe traumatic haemorrhage. Fibrinogen is one of the first coagulation factors to become depleted in TIC and evidence suggests that severely injured trauma patients with hypofibrinogenaemia have poor outcomes. It is postulated that early fibrinogen replacement can improve clinical outcomes. This study investigated cryoprecipitate transfusion in hyopfibrinogeneamic trauma patients. METHODS: This retrospective, single center, observational study investigated the use of cryoprecipitate in severely injured trauma patients admitted to an Australian Level I Trauma Centre. The primary outcome was time to administration of cryoprecipitate after identification of hypofibrinogenaemia using ROTEM (FIBTEM A5). Data collected included demographics, ISS, laboratory values of coagulation and blood product usage. RESULTS: 71 patients received cryoprecipitate with a median time of 61 minutes [IQR 37-93] from FIBTEM A5 result to initial cryoprecipitate administration. At 24 hours following admission to ED, Clauss Fibrinogen levels increased by 1.30g/L [IQR 0.45-1.85] and FIBTEM A5 assay increased by 8mm [IQR 3.0-11.3]. Changes in both variables were highly significant (p<0.001) and Clauss Fibrinogen versus FIBTEM A5 values showed moderate to strong correlation (R=0.75-0.80). CONCLUSION: This study demonstrated that early administration of cryoprecipitate was both feasible and efficacious in fibrinogen replacement in severe traumatic haemorrhage. High-level evidence supporting cryoprecipitate or fibrinogen concentrate replacement with regards to efficacy and feasibility is required to guide future clinical practice. This study provided baseline data to inform the design of further clinical trials investigating fibrinogen replacement in traumatic haemorrhage.

Targeted fibrinogen concentrate use in severe traumatic haemorrhage.

OBJECTIVE: Fibrinogen is one of the first coagulation factors to be depleted during traumatic haemorrhage, and evidence suggests hypofibrinogenaemia leads to poor outcomes. A number of fibrinogen replacement products are currently available, with no clear consensus on the ideal product to use in severe traumatic haemorrhage. We hypothesised that it will be possible to rapidly administer fibrinogen concentrate (FC) guided by rotational thromboelastometry (ROTEM) FIBTEM A5 in patients presenting with trauma haemorrhage. METHODS: We examined 36 consecutive patients with trauma admitted to a level 1 trauma centre in Australia who received FC as part of their initial resuscitation. ROTEM analysis was conducted at various time points from emergency department (ED) admission to 48 hours after admission. The primary outcome was time to administration of FC after identification of hypofibrinogenaemia using ROTEM FIBTEM A5. Data were collected on quantity and timing of product transfusion, demographics, Injury Severity Score and laboratory values of coagulation. Spearman rank order correlation was used to determine the correlation between FIBTEM A5 and Clauss fibrinogen (FibC). RESULTS: Thirty-six patients received FC as their initial form of fibrinogen replacement during the study. Patients were hypofibrinogenaemic by both FIBTEM A5 (6 mm) and FibC (1.7 g/L) on presentation to the ED. It took a median of 22 minutes (IQR, 17-30 minutes) from time of a FIBTEM A5 analysis to FC administration. Both parameters increased significantly (P < 0.05) by 24 hours after admission. CONCLUSION: This study suggests that administration of FC represents a rapid and feasible method to replace fibrinogen in severe traumatic haemorrhage. However, the optimal method for replacing fibrinogen in traumatic haemorrhage is controversial and large multicentre randomised controlled trials are needed to provide further evidence. This study provided baseline data to inform the design of further clinical trials investigating fibrinogen replacement in traumatic haemorrhage.
