Association Between Whole Blood Transfusion and Mortality Among Injured Pediatric Patients.

OBJECTIVE: The aim of this study was to assess the association between whole blood (WB) and mortality among injured children who received immediate blood transfusion. BACKGROUND: The use of WB for transfusion therapy in trauma has been revisited, and recent studies have reported an association between WB and improved survival among adults. However, evidence of a similar association lacks in children. METHODS: We performed a retrospective cohort study from the American College of Surgeons Trauma Quality Improvement Program (ACS-TQIP) between 2020 and 2021. Patients were aged less than or equal to 16 years and had immediate blood transfusion within 4 hours of hospital arrival. Survival at 24 hours and 30 days were compared after creating 1:1 propensity score-matched cohorts, matching for demographics, injury type, vital signs on admission, trauma severity scores, hemorrhage control procedures, hospital characteristics, and the need for massive transfusion. RESULTS: A total of 2729 patients were eligible for analysis. The median age was 14 years (interquartile range: 8-16 years); 1862 (68.2%) patients were male; and 1207 (44.2%) patients were White. A total of 319 (11.7%) patients received WB. After a 1:1 ratio propensity score matching, 318 matched pairs were compared. WB transfusion was associated with improved survival at 24 hours, demonstrating a 42% lower risk of mortality (hazard ratio, 0.58; 95% CI, 0.34-0.98; P =0.042) Similarly, the survival benefit associated with WB transfusion remained consistent at 30 days (hazard ratio, 0.65; 95% CI, 0.46-0.90; P =0.011). CONCLUSION: The use of WB was associated with improved survival among injured pediatric patients requiring immediate transfusion.

Dollars and Sense: The Financial Argument for Dedicated Posttrauma Center Care.

OBJECTIVE: To demonstrate that the creation of a Center for Trauma Survivorship (CTS) is not cost-prohibitive but is a revenue generator for the institution. BACKGROUND: A dedicated CTS has been demonstrated to increase adherence with follow-up visits and improve overall aftercare in severely injured patients discharged from the trauma center. A potential impediment to the creation of similar centers is its assumed prohibitive cost. METHODS: This pre and post-cohort study examines the financial impact of patients treated by the CTS. Patients in the PRE cohort were those treated in the year before CTS inception. Eligibility criteria are trauma patients admitted who are ≥18 years of age and have a New Injury Severity Score ≥16 or intensive care unit stay ≥2 days. Financial data were obtained from the hospital's billing and cost accounting systems for a 1-year time period after discharge. RESULTS: There were 176 patients in the PRE and 256 in the CTS cohort. The CTS cohort generated 1623 subsequent visits versus 748 in the PRE cohort. CTS patients underwent more follow-up surgery in their first year of recovery as compared with the PRE cohort (98 vs 26 procedures). Each CTS patient was responsible for a $7752 increase in net revenue with a positive contribution margin of $4558 compared with those in the PRE group. CONCLUSIONS: A dedicated CTS increases subsequent visits and necessary procedures and is a positive revenue source for the trauma center. The presumptive financial burden of a CTS is incorrect and the creation of dedicated centers will improve patients' outcomes and the institution's bottom line.

Early Cold Stored Platelet Transfusion Following Severe Injury: A Randomized Clinical Trial.

OBJECTIVE: To determine the feasibility, efficacy, and safety of early cold stored platelet transfusion compared with standard care resuscitation in patients with hemorrhagic shock. BACKGROUND: Data demonstrating the safety and efficacy of early cold stored platelet transfusion are lacking following severe injury. METHODS: A phase 2, multicenter, randomized, open label, clinical trial was performed at 5 US trauma centers. Injured patients at risk of large volume blood transfusion and the need for hemorrhage control procedures were enrolled and randomized. The intervention was the early transfusion of a single apheresis cold stored platelet unit, stored for up to 14 days versus standard care resuscitation. The primary outcome was feasibility and the principal clinical outcome for efficacy and safety was 24-hour mortality. RESULTS: Mortality at 24 hours was 5.9% in patients who were randomized to early cold stored platelet transfusion compared with 10.2% in the standard care arm (difference, -4.3%; 95% CI, -12.8% to 3.5%; P =0.26). No significant differences were found for any of the prespecified ancillary outcomes. Rates of arterial and/or venous thromboembolism and adverse events did not differ across treatment groups. CONCLUSIONS AND RELEVANCE: In severely injured patients, early cold stored platelet transfusion is feasible, safe and did not result in a significant lower rate of 24-hour mortality. Early cold stored platelet transfusion did not result in a higher incidence of arterial and/or venous thrombotic complications or adverse events. The storage age of the cold stored platelet product was not associated with significant outcome differences. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT04667468.

When Equality Is Not Equity: The Ethics of Access to Trauma Care: A Surgical Perspective.

OBJECTIVE: The purpose of this surgical perspective is to describe the trauma care needs of the South Side of Chicago and the creation of an adult trauma center at the University of Chicago Medicine and associated hospital-based violence intervention program. BACKGROUND: Traumatic injury is a leading cause of death and disability in the United States. Disparities across the continuum of trauma care exist, which are often rooted in the social determinants of health. Trauma center distribution is critical to timely treatment and should be based on the trauma needs of the area. The previous trauma ecosystem of Chicago was incongruent with the concentration of violent injuries on the south and west sides of the city, leading to a fallacy of distributive justice. METHODS: A descriptive analysis of community partners, trauma program leadership, trauma surgeons, and the violence intervention program director was performed. RESULTS: The UCM trauma center opened in May 2018 and has since been one of the busiest trauma centers in the country, with a 40% penetrating trauma rate. There have been significant reductions in patient transport time on the South Side up to 8.9 minutes ( P <0.001). The violence intervention program employs credible messengers with lived experience representing the community and has engaged over 8000 patients since 2018, developing both community-based and medical-legal partnerships. CONCLUSIONS: The persistent efforts of the community and key stakeholders led to a system change that improved trauma care for the South Side of Chicago.

The Efficacy of Low-Titer Group O Whole Blood Compared With Component Therapy in Civilian Trauma Patients: A Meta-Analysis.

OBJECTIVES: To assess if transfusion with low-titer group O whole blood (LTOWB) is associated with improved early and/or late survival compared with component blood product therapy (CT) in bleeding trauma patients. DATA SOURCES: A systematic search of PubMed, CINAHL, and Web of Science was performed from their inception through December 1, 2023. Key terms included injury, hemorrhage, bleeding, blood transfusion, and whole blood. STUDY SELECTION: All studies comparing outcomes in injured civilian adults and children who received LTOWB versus CT were included. DATA EXTRACTION: Data including author, publication year, sample size, total blood volumes, and clinical outcomes were extracted from each article and reported following the Meta-analysis Of Observational Studies in Epidemiology guidelines. Main outcomes were 24-hour (early) and combined 28-day, 30-day, and in-hospital (late) mortality rates between recipients of LTOWB versus CT, which were pooled using random-effects models. DATA SYNTHESIS: Of 1297 studies reviewed, 24 were appropriate for analysis. Total subjects numbered 58,717 of whom 5,164 received LTOWB. Eleven studies included adults-only, seven included both adults and adolescents, and six only included children. The median (interquartile range) age for patients who received LTOWB and CT was 35 years (24-39) and 35.5 years (23-39), respectively. Overall, 14 studies reported early mortality and 22 studies reported late mortality. LTOWB was associated with improved 24-hour survival (risk ratios [RRs] [95% CI] = 1.07 [1.03-1.12]) and late (RR [95% CI] = 1.05 [1.01-1.09]) survival compared with component therapy. There was no evidence of small study bias and all studies were graded as a moderate level of bias. CONCLUSIONS: These data suggest hemostatic resuscitation with LTOWB compared with CT improves early and late survival outcomes in bleeding civilian trauma patients. The majority of subjects were injured adults; multicenter randomized controlled studies in injured adults and children are underway to confirm these findings.

Insights from CTTACC: immune system reset by cellular therapies for chronic illness after trauma, infection, and burn.

BACKGROUND AIMS: In this paper, we present a review of several selected talks presented at the CTTACC conference (Cellular Therapies in Trauma and Critical Care) held in Scottsdale, AZ in May 2023. This conference review highlights the potential for cellular therapies to "reset" the dysregulated immune response and restore physiologic functions to normal. Improvements in medical care systems and technology have increasingly saved lives after major traumatic events. However, many of these patients have complicated post-traumatic sequelae, ranging from short-term multi-organ failure to chronic critical illness. METHODS/RESULTS: Patients with chronic critical illness have been found to have dysregulated immune responses. These abnormal and harmful immune responses persist for years after the initial insult and can potentially be mitigated by treatment with cellular therapies. CONCLUSIONS: The sessions emphasized the need for more research and clinical trials with cellular therapies for the treatment of a multitude of chronic illnesses: post-trauma, radiation injury, COVID-19, burns, traumatic brain injury (TBI) and other chronic infections.

Deploying whole blood to the battlefield-The Israel Defense Forces Medical Corps initial experience during the 2023 war.

BACKGROUND: Military and prehospital medical organizations invest significant resources to advance the treatment of trauma patients aiming to reduce preventable deaths. Focus is on hemorrhage control and volume resuscitation with blood products, with adoption of Remote Damage Control Resuscitation (RDCR) guidelines. The Israel Defense Forces Medical Corps (IDF-MC) has been using tranexamic acid and freeze-dried plasma (FDP) as part of its RDCR protocol for more than a decade. In recent years, low-titer group O whole blood (LTOWB) has been integrated, on IDF evacuation helicopters and expanded to mobile ambulances, complementing FDP use in treating trauma patients in state of profound shock. STUDY DESIGN AND METHODS: During the war that erupted in October 2023, the IDF-MC made a decision to bring LTOWB forward, and to equip every combat brigade level mobile intensive care units with LTOWB, onboard armored vehicles. The goal was to make whole blood available as close as possible to the point of injury and within minutes from time of injury. RESULTS AND DISCUSSION: We describe the IDF-MCs' efforts to bring LTOWB to the front lines and present four cases in which LTOWB was administered. All patients were young male, with significant blood loss following penetrating injuries. One patient died in the operating room, following hospital arrival and emergency thoracotomy. The others survived. Our initial experience with bringing LTOWB as close as possible to the point of injury during high intensity fighting is encouraging, showing patient benefit along with logistic feasibility. After action reports and data collection will continue.

Ethical considerations in the use of RhD-positive blood products in trauma.

BACKGROUND: Prehospital and early in-hospital use of low titer group O whole blood (LTOWB) for life-threatening bleeding has been independently associated with improved survival compared to component therapy. However, when RhD-positive blood products are administered to RhD-negative females of childbearing potential (FCP), there is a small future risk of hemolytic disease of the fetus and newborn (HDFN). This raises important ethical questions that must be explored in order to justify the use of RhD-positive blood products, including LTOWB, both in clinical practice and research. METHODS: This essay explores the ethical challenges related to RhD-positive blood product administration to RhD-negative or RhD-unknown FCPs as a first-line resuscitation fluid in the trauma setting. These ethical issues include: issues related to decision-making, ethical analysis based on the doctrine of double effect (DDE), and attendant obligations incurred by hospitals that administer RhD-positive blood to FCPs. RESULTS: Ethical analysis through the use of the DDE demonstrates that utilization of RhD-positive blood products, including LTOWB, in the early resuscitation of FCPs is an ethically appropriate approach. By accepting the risk of HDFN, hospitals generate obligations to promote blood donation, evaluate for alloimmunization and counsel patients on the future risk of HDFN, and maintain an understanding of the ethical rationale for RhD-positive blood transfusion.

Massive transfusion protocol reactivation as a novel marker of physician team under-triage after injury.

BACKGROUND: Large trauma centers have protocols for the assessment of injury and triaging of care with attempts to over-triage to ensure adequate care for all patients. We noted that a significant number of patients undergo a second massive transfusion protocol (MTP) activation in the first 24 h of care and conducted a retrospective cohort study of patients involved over a 3-year period. METHODS: Transfusion service records of MTP activations 2019-2021 were linked to Trauma Registry records and divided into cohorts receiving a single versus a reactivation of the MTP. Time of activation and amounts of blood products issued were linked to demographic, injury severity, and outcome data. Categorical and continuous data were compared between cohorts with chi-squared, Fisher's, and Wilcoxan tests as appropriate, and multivariable regression models were used to seek interactions (p < .05). RESULTS: MTP activation was recorded for 1884 acute trauma patients over our 3-year study period, 142 of whom (7.5%) had reactivation. Factors associated with reactivation included older age (46 vs. 40 years), higher injury severity score (ISS, 27 vs. 22), leg injuries, and presentation during morning shift change (5-7 a.m., 3.3% vs. 7.7%). Patients undergoing MTP reactivation used more RBCs (5 U vs. 2 U) and had more ICU days (3 vs. 2). CONCLUSIONS: Older patients and those presenting during shift change are at risk for failure to recognize their complex injury patterns and under-triage for trauma care. The fidelity and granularity of transfusion service records can provide unique opportunities for quality assessment and improvement in trauma care.

Blood consumption in the Role 2 setting: A Department of Defense Trauma Registry analysis.

BACKGROUND: The Role 2 setting represents the most far-forward military treatment facility with limited surgical and holding capabilities. There are limited data to guide recommendations on blood product utilization at the Role 2. We describe the consumption of blood products in this setting. STUDY DESIGN AND METHODS: We analyzed data from 2007 to 2023 from the Department of Defense Trauma Registry (DODTR) that received care at a Role 2. We used descriptive and inferential statistics to characterize the volumes of blood products consumed in this setting. We also performed a secondary analysis of US military, Coalition, and US contractor personnel. RESULTS: Within our initial cohort analysis of 15,581 encounters, 17% (2636) received at least one unit of PRBCs or whole blood, of which 11% received a submassive transfusion, 4% received a massive transfusion, and 1% received a supermassive transfusion. There were 6402 encounters that met inclusion for our secondary analysis. With this group, 5% received a submassive transfusion, 2% received a massive transfusion, and 1% received a supermassive transfusion. CONCLUSIONS: We described volumes of blood products consumed at the Role 2 during recent conflicts. The maximum number of units consumed among survivors exceeds currently recommended available blood supply. Our findings suggest that rapid resupply and cold-stored chain demands may be higher than anticipated in future conflicts.

The first two years of the use of low titer group O whole blood during French Military overseas operations: A retrospective study.

BACKGROUND: On the battlefield, hemorrhage is the main cause of potentially preventable death. To reduce mortality due to hemorrhagic injuries, the French Military Medical Service (FMMS) has deployed low titer group O whole blood (LTOWB) since June 2021 during operation BARKHANE in the Sahel-Saharan strip. Questions persist regarding the circumstances under which the FMMS employs LTOWB during overseas operations. STUDY DESIGN: We performed a retrospective analysis of all LTOWB transfused by the FMMS during overseas operations in the Sahel-Saharan strip between June 1, 2021, and June 1, 2023. Information was collected from battlefield forward transfusion sheets. RESULTS: Over the 2-year study period, 40 units of LTOWB were transfused into 25 patients. Of the 25 patients, 18 were combat casualties and seven were transfused for non-trauma surgery. Of the 40 units of LTOWB transfused, 22 were provided during Role 2 care, 11 during tactical medical evacuation (MEDEVAC), and seven in light and mobile surgical units. Among combat casualties, LTOWB was the first blood product transfused in 13 patients. In combat casualties, 6 h post-trauma, the median ratio of plasma: red blood cells (RBCs) was 1.5, and the median equivalent platelet concentrate (PC) transfused was 0.17. No immediate adverse events related to LTOWB transfusion were reported. CONCLUSION: LTOWB is transfused by the FMMS during overseas operations from the tactical MEDEVAC until Role 2 care. Deployment of LTOWB by the FMMS enables an early high-ratio plasma/RBC transfusion and an early platelet transfusion for combat casualties.

Survey of policies at US hospitals on the selection of RhD type of low-titer O whole blood for use in trauma resuscitation.

BACKGROUND: Low-titer group O whole blood (LTOWB) use is increasing due to data suggesting improved outcomes and safety. One barrier to use is low availability of RhD-negative LTOWB. This survey examined US hospital policies regarding the selection of RhD type of blood products in bleeding emergencies. STUDY DESIGN AND METHODS: A web-based survey of blood bank directors was conducted to determine their hospital's RhD-type selection policies for blood issued for massive bleeding. RESULTS: There was a 61% response rate (101/157) and of those responses, 95 were complete. Respondents indicated that 40% (38/95) use only red blood cells (RBCs) and 60% (57/95) use LTOWB. For hospitals that issue LTOWB (N = 57), 67% are supplied only with RhD-positive, 2% only with RhD-negative, and 32% with both RhD-positive and RhD-negative LTOWB. At sites using LTOWB, RhD-negative LTOWB is used exclusively or preferentially more commonly in adult females of childbearing potential (FCP) (46%) and pediatric FCP (55%) than in men (4%) and boys (24%). RhD-positive LTOWB is used exclusively or preferentially more commonly in men (94%) and boys (54%) than in adult FCP (40%) or pediatric FCP (21%). At sites using LTOWB, it is not permitted for adult FCPs at 12%, pediatric FCP at 21.4%, and boys at 17.1%. CONCLUSION: Hospitals prefer issuing RhD-negative LTOWB for females although they are often ineligible to receive RhD-negative LTOWB due to supply constraints. The risk and benefits of LTOWB compared to the rare occurrence of hemolytic disease of the fetus/newborn (HDFN) need further examination in the context of withholding a therapy for females that has the potential for improved outcomes.

A survey of low titer O whole blood use within the trauma quality improvement program registry.

INTRODUCTION: The use of low titer O whole blood (LTOWB) has expanded although it remains unclear how many civilian trauma centers are using LTOWB. METHODS: We analyzed data on civilian LTOWB recipients in the American College of Surgeons Trauma Quality Improvement Program (TQIP) database 2020-2021. Unique facility keys were used to determine the number of centers that used LTOWB in that period. RESULTS: A total of 16,603 patients received LTOWB in the TQIP database between 2020 and 2021; 6600 in 2020, and 10,003 in 2021. The total number of facilities that reported LTOWB use went from 287/779 (37%) in 2020 to 302/795 (38%) in 2021. Between 2020 and 2021, among all level 1-3 designated trauma facilities that report to TQIP LTOWB use increased at level-1 centers (118 to 129), and level-2 centers (81 to 86), but decreased in level-3 facilities (9 to 4). Among pediatric and dual pediatric-adult designated hospitals there was a decrease in the number of pediatric level-1 centers (29 to 28) capable of administering LTOWB. Among centers with either single or dual level-1 trauma center designation with adult centers, the number that administered LTOWB to injured pediatric patients also decreased from 17 to 10, respectively. CONCLUSIONS: There was an increase in the number of facilities transfusing LTOWB between 2020 and 2021. The use of LTOWB is underutilized in children at centers that have it available. These findings inform the expansion of LTOWB use in trauma.

Maternal and child life years gained by transfusing low titer group O whole blood in trauma: A computer simulation.

BACKGROUND: Using low titer group O whole blood (LTOWB) is increasingly popular for resuscitating trauma patients. LTOWB is often RhD-positive, which might cause D-alloimmunization and hemolytic disease of the fetus and newborn (HDFN) if transfused to RhD-negative females of childbearing potential (FCP). This simulation determined the number of life years gained by the FCP and her future children if she was resuscitated with LTOWB compared with conventional component therapy (CCT). METHODS: The model simulated 500,000 injured FCPs of each age between 0 and 49 years with LTOWB mortality relative reductions (MRRs) compared with components between 0.1% and 25%. For each surviving FCP, number of life years gained was calculated using her age at injury and average life expectancy for American women. The number of expected future pregnancies for FCPs that did not survive was also based on her age at injury; each future child was assigned the maximum lifespan unless they suffered perinatal mortality or serious neurological events from HDFN. RESULTS: The LTOWB group with an MRR 25% compared with CCT had the largest total life years gained. The point of equivalence for RhD-positive LTOWB compared to CCT, where life years lost due to severe HDFN was equivalent to life years gained due to FCP survival/future childbearing, occurred at an MRR of approximately 0.1%. CONCLUSION: In this model, RhD-positive LTOWB resulted in substantial gains in maternal and child life years compared with CCT. A >0.1% relative mortality reduction from LTOWB offset the life years lost to HDFN mortality and severe neurological events.

Association of freeze-dried plasma with 24-h mortality among trauma patients at risk for hemorrhage.

BACKGROUND: Blood products form the cornerstone of contemporary hemorrhage control but are limited resources. Freeze-dried plasma (FDP), which contains coagulation factors, is a promising adjunct in hemostatic resuscitation. We explore the association between FDP alone or in combination with other blood products on 24-h mortality. STUDY DESIGN AND METHODS: This is a secondary data analysis from a cross-sectional prospective observational multicenter study of adult trauma patients in the Western Cape of South Africa. We compare mortality among trauma patients at risk of hemorrhage in three treatment groups: Blood Products only, FDP + Blood Products, and FDP only. We apply inverse probability of treatment weighting and fit a multivariable Cox proportional hazards model to assess the hazard of 24-h mortality. RESULTS: Four hundred and forty-eight patients were included, and 55 (12.2%) died within 24 h of hospital arrival. Compared to the Blood Products only group, we found no difference in 24-h mortality for the FDP + Blood Product group (p = .40) and a lower hazard of death for the FDP only group (hazard = 0.38; 95% CI, 0.15-1.00; p = .05). However, sensitivity analyses showed no difference in 24-h mortality across treatments in subgroups with moderate and severe shock, early blood product administration, and accounting for immortal time bias. CONCLUSION: We found insufficient evidence to conclude there is a difference in relative 24-h mortality among trauma patients at risk for hemorrhage who received FDP alone, blood products alone, or blood products with FDP. There may be an adjunctive role for FDP in hemorrhagic shock resuscitation in settings with significantly restricted access to blood products.

Comparison of helicopter and ground transportation in pediatric trauma patients.

BACKGROUND: Decision making regarding transportation mode after a traumatic injury may have a significant impact on outcomes, due to differences in time to definitive care. The objective of this study was to determine if transport mode had an impact on in-hospital mortality and discharge disposition in pediatric trauma patients. METHODS: Data were abstracted from the National Trauma Data Bank from 2007 to 2016 comparing helicopter and ground transportation modes effects on mortality and discharge outcomes. The primary outcome was in-hospital death, while the secondary outcome was discharge home without services (DCHWOS). Analyses included logistic regression modeling and propensity score matching. RESULTS: Significant variables from univariate analysis were included in the multivariate, propensity-matched regression model. Pediatric trauma patients transported by helicopter had lower odds of mortality (OR 0.69 [0.64,0.75]) and higher odds of DCHWOS (1.29 [1.20,1.39]). There were no differences in overall mechanism, but individual injury patterns showed higher odds of mortality. CONCLUSION: Critical decisions regarding triage of patients by different modes of transport occur every day. This study supports the current literature on the topic and shows a potential additional benefit of a meaningful discharge outcome for those transported by helicopter. IMPACT: This study may impact prehospital triage decision making process for pediatric trauma patients on mortality. Prehospital transport mode may contribute to pediatric trauma discharge outcomes. Highlights the need for future research regarding non-clinical data that is unable to be abstracted from national databases (e.g., family dynamics, insurance status, weather, access to post-discharge resources).

Blood lactate after pre-hospital blood transfusion for major trauma by helicopter emergency medical services.

BACKGROUND AND OBJECTIVES: The appropriate use of blood components is essential for ethical use of a precious, donated product. The aim of this study was to report in-hospital red blood cell (RBC) transfusion after pre-hospital transfusion by helicopter emergency medical service paramedics. A secondary aim was to assess the potential for venous blood lactate to predict ongoing transfusion. MATERIALS AND METHODS: All patients who received RBC in air ambulance were transported to a single adult major trauma centre, had venous blood lactate measured on arrival and did not die before ability to transfuse RBC were included. The association of venous blood lactate with ongoing RBC transfusion was assessed using multi-variable logistic regression analysis and reported using adjusted odds ratios (aOR). The discriminative ability of venous blood lactate was assessed using area under receiver operating characteristics curve (AUROC). RESULTS: From 1 January 2016 to 15 May 2019, there were 165 eligible patients, and 128 patients were included. In-hospital transfusion occurred in 97 (75.8%) of patients. Blood lactate was associated with ongoing RBC transfusion (aOR: 2.00; 95% confidence interval [CI]: 1.36-2.94). Blood lactate provided acceptable discriminative ability for ongoing transfusion (AUROC: 0.78; 95% CI: 0.70-0.86). CONCLUSIONS: After excluding patients with early deaths, a quarter of those who had prehospital RBC transfusion had no further transfusion in hospital. Venous blood lactate appears to provide value in identifying such patients. Lactate levels after pre-hospital transfusion could be used as a biomarker for transfusion requirement after trauma.

Geriatric Motorcycle-Related Outcomes: A Pennsylvania Multicenter Study.

INTRODUCTION: Geriatric patients (GeP) often experience increased morbidity and mortality following traumatic insult and as a result, require more specialized care due to lower physiologic reserve and underlying medical comorbidities. Motorcycle injuries (MCCI) occur across all age groups; however, no large-scale studies evaluating outcomes of GeP exist for this particular subset of patients. Data thus far are limited to elderly participation in recreational activities such as water and alpine skiing, snowboarding, equestrian, snowmobiles, bicycles, and all-terrain vehicles. We hypothesized that GeP with MCCI will have a higher rate of mortality when compared with their younger counterparts despite increased helmet usage. METHODS: We performed a multicenter retrospective review of MCCI patients at three Pennsylvania level I trauma centers from January 2016 to December 2020. Data were extracted from each institution's electronic medical records and trauma registry. GeP were defined as patients aged more than or equal to 65 y. The primary outcome was mortality. Secondary outcomes included ventilator days; hospital, intensive care unit, and intermediate unit length of stays; complications; and helmet use. 3:1 nongeriatric patients (NGeP) to GeP propensity score matching (PSM) was based on sex, abbreviated injury scale (AIS), and injury severity score (ISS). P ≤ 0.05 was considered significant. RESULTS: One thousand five hundred thirty eight patients were included (GeP: 7% [n = 113]; NGP: 93% [n = 1425]). Prior to PSM, GeP had higher median Charlson Comorbidity Index (GeP: 3.0 versus NGeP: 0.0; P ≤ 0.001) and greater helmet usage (GeP: 73.5% versus NGeP: 54.6%; P = 0.001). There was a statistically significant difference between age cohorts in terms of ISS (GeP: 10.0 versus NGeP: 6.0, P = 0.43). There was no significant difference for any AIS body region. Mortality rates were similar between groups (GeP: 1.7% versus NGeP: 2.6%; P = 0.99). After PSM matching for sex, AIS, and ISS, GeP had significantly more comorbidities than NGeP (P ≤ 0.05). There was no difference in trauma bay interventions or complications between cohorts. Mortality rates were similar (GeP: 1.8% versus NGeP: 3.2%; P = 0.417). Differences in ventilator days as well as intensive care unit length of stay, intermediate unit length of stay, and hospital length of stay were negligible. Helmet usage between groups were similar (GeP: 64.5% versus NGeP: 66.8%; P = 0.649). CONCLUSIONS: After matching for sex, ISS, and AIS, age more than 65 y was not associated with increased mortality following MCCI. There was also no significant difference in helmet use between groups. Further studies are needed to investigate the effects of other potential risk factors in the aging patient, such as frailty and anticoagulation use, before any recommendations regarding management of motorcycle-related injuries in GeP can be made.

Systematic Literature Review of Health-Related Quality-of-Life Measures for Caregivers of Older Adult Trauma Patients.

INTRODUCTION: As the older adult population increases, hospitals treat more older adults with injuries. After leaving, these patients suffer from decreased mobility and independence, relying on care from others. Family members often assume this responsibility, mostly informally and unpaid. Caregivers of other older adult populations have increased stress and decreased caregiver-related quality of life (CRQoL). Validated CRQoL measures are essential to capture their unique experiences. Our objective was to review existing CRQoL measures and their validity in caregivers of older adult trauma patients. METHODS: A professional librarian searched published literature from the inception of databases through August 12, 2022 in MEDLINE (via PubMed), Embase (via Elsevier), and CINAHL Complete (via EBSCO). We identified 1063 unique studies of CRQoL in caregivers for adults with injury and performed a systematic review following COnsensus-based Standards for the selection of health Measurement Instruments guidelines for CRQoL measures. RESULTS: From the 66 studies included, we identified 54 health-related quality-of-life measures and 60 domains capturing caregiver-centered concerns. The majority (83%) of measures included six or fewer CRQoL content domains. Six measures were used in caregivers of older adults with single-system injuries. There were no validated CRQoL measures among caregivers of older adult trauma patients with multisystem injuries. CONCLUSIONS: While many measures exist to assess healthcare-related quality of life, few, if any, adequately assess concerns among caregivers of older adult trauma patients. We found that CRQoL domains, including mental health, emotional health, social functioning, and relationships, are most commonly assessed among caregivers. Future measures should focus on reliability and validity in this specific population to guide interventions.

Educational Strategies in Pediatric Trauma Resuscitation Across Disciplines: A Scoping Review.

INTRODUCTION: Trauma is the leading cause of death and disability in children. Differences in mechanism, injury pattern, severity, and physiology in this population distinguish pediatric trauma patients from adults. Educational techniques including simulation and didactics may improve pediatric readiness in this setting. We summarize the literature across disciplines, highlighting the curricular approaches, target provider population, educational content, content delivery method, and Kirkpatrick level for pediatric trauma resuscitation education. METHODS: The MEDLINE (via Ovid), Embase (via Elsevier), Cumulative Index to Nursing & Allied Health Literature Complete (via EBSCO), Education Database (via ProQuest), and Web of Science Social Science Citation Index and Science Citation Index (via Clarivate) were searched. We reviewed 90 manuscripts describing pediatric trauma resuscitation education programs. When available, target provider population, curricular content, delivery method, and Kirkpatrick level were obtained. RESULTS: Nurses (50%), residents (45%), and attending physicians (43%) were the most common participants. Airway management (25%), shock (25%), and general trauma (25%) were the most frequently taught concepts, and delivery of content was more frequently via simulation (65%) or didactics (52%). Most studies (39%) were Kirkpatrick Level 1. CONCLUSIONS: This review suggests that diverse strategies exist to promote pediatric readiness. Most training programs are interdisciplinary and use a variety of educational techniques. However, studies infrequently report examining the impact of educational interventions on patient-centered outcomes and lack detail in describing their curriculum. Future educational efforts would benefit from heightened attention to such outcome measures and a rigorous description of their curricula to allow for reproducibility.
