Maintaining a whole blood-centered transfusion improves survival in hemorrhagic resuscitation.

BACKGROUND: Whole blood (WB) transfusion has been shown to improve mortality in trauma resuscitation. The optimal ratio of packed red blood cells (pRBC) to WB in emergent transfusion has not been determined. We hypothesized that a low pRBC/WB transfusion ratio is associated with improved survival in trauma patients. METHODS: We analyzed the 2021 Trauma Quality Improvement Program (TQIP) database to identify patients who underwent emergent surgery for hemorrhage control and were transfused within 4 hours of hospital arrival, excluding transfers or deaths in the emergency department. We stratified patients based on pRBC/WB ratios. The primary outcome was mortality at 24 hours. Logistic regression was performed to estimate odds of mortality among ratio groups compared with WB alone, adjusting for injury severity, time to intervention, and demographics. RESULTS: Our cohort included 17,562 patients; of those, 13,678 patients had only pRBC transfused and were excluded. Fresh frozen plasma/pRBC ratio was balanced in all groups. Among those who received WB (n = 3,884), there was a significant increase in 24-hour mortality with higher pRBC/WB ratios (WB alone 5.2%, 1:1 10.9%, 2:1 11.8%, 3:1 14.9%, 4:1 20.9%, 5:1 34.1%, p = 0.0001). Using empirical cutpoint estimation, we identified a 3:1 ratio or less as an optimal cutoff point. Adjusted odds ratios of 24-hour mortality for 4:1 and 5:1 groups were 2.85 (95% confidence interval [CI], 1.19-6.81) and 2.89 (95% CI, 1.29-6.49), respectively. Adjusted hazard ratios of 24-hour mortality were 2.83 (95% CI, 1.18-6.77) for 3:1 ratio, 3.67 (95% CI, 1.57-8.57) for 4:1 ratio, and 1.97 (95% CI, 0.91-4.23) for 5:1 ratio. CONCLUSION: Our analysis shows that higher pRBC/WB ratios at 4 hours diminished survival benefits of WB in trauma resuscitation. Further efforts should emphasize this relationship to optimize trauma resuscitation protocols. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

Comparison of surgical stabilization of rib fractures vs epidural analgesia on in-hospital outcomes.

INTRODUCTION: Surgical stabilization of rib fractures (SSRF) improves functional outcomes compared to controls, partly due to reduction in pain. We investigated the impact of early SSRF on pulmonary complications, mortality, and length of stay compared to non-operative analgesia with epidural analgesia (EA). METHODS: Retrospective cohort study of the Trauma Quality Improvement Program (TQIP) 2017 dataset for adults with rib fractures, excluding those with traumatic brain injury or death within twenty-four hours. Early SSRF and EA occurred within 72 h, and we excluded those who received both or neither intervention. Our primary outcome was a composite of pulmonary complications including acute respiratory distress syndrome (ARDS) or ventilator-associated pneumonia (VAP). Additional outcomes included unplanned endotracheal intubation, in-hospital mortality, and hospital and intensive care unit (ICU) length of stay (LOS) for those surviving to discharge. Multiple logistic and linear regressions were controlled for variables including age, sex, flail chest (FC), injury severity, additional procedures, and medical comorbidities. RESULTS: We included 1,024 and 1,109 patients undergoing early SSRF and EA, respectively. SSRF patients were more severely injured with higher rates of FC (42.8 vs 13.3%, p<0.001), Injury Severity Score (ISS) > 16 (56.9 vs 36.1%, p<0.001), and Abbreviated Injury Scale (AIS) Thorax > 3 (33.3 vs 12.2%, p<0.001). Overall, 49 (2.3%) of patients developed ARDS or VAP, 111 (5.2%) required unplanned intubation, and 58 (2.7%) expired prior to discharge. On multivariable analysis, SSRF was not associated with the primary composite outcome (OR: 1.65, 95%CI: 0.85-3.21). Early SSRF significantly predicted decreased risk of unplanned intubation (OR:0.59, 95%CI: 0.38-0.92) compared with early EA alone, however, was not a significant predictor of in-hospital mortality (OR: 1.27, 95%CI: 0.68-2.39). SSRF was associated with significantly longer hospital (Exp(ß): 1.06, 95%CI: 1.00-1.12, p = 0.047) and ICU LOS (Exp(ß): 1.17, 95%CI: 1.08-1.27, p<0.001). CONCLUSIONS: Aside from unplanned intubation, we observed no statistically significant difference in the adjusted odds of in-hospital pulmonary morbidity or mortality for patients undergoing early SSRF compared with early EA. Chest wall injury patients may benefit from referral to trauma centers where both interventions are available and appropriate surgical candidates may receive timely intervention.

Successful Community Discharge Among Older Adults With Traumatic Brain Injury Admitted to Inpatient Rehabilitation Facilities.

Objective: To identify admission characteristics that predict a successful community discharge from an inpatient rehabilitation facility (IRF) among older adults with traumatic brain injury (TBI). Design: In a retrospective cohort study, we leveraged probabilistically linked Medicare Administrative, IRF-Patient Assessment Instrument, and National Trauma Data Bank data to build a parsimonious logistic model to identify characteristics associated with successful discharge. Multiple imputation methods were used to estimate effects across linked datasets to account for potential data linkage errors. Setting: Inpatient Rehabilitation Facilities in the U.S. Participants: The sample included a mean of 1060 community-dwelling adults aged 66 years and older across 30 linked datasets (N=1060). All were hospitalized after TBI between 2011 and 2015 and then admitted to an IRF. The mean age of the sample was 79.7 years, and 44.3% of the sample was women. Interventions: Not applicable. Main Outcome Measures: Successful discharge home. Results: Overall, 64.6% of the sample was successfully discharged home. A logistic model including 4 predictor variables: Functional Independence Measure motor (FIM-M) and cognitive (FIM-C) scores, pre-injury chronic conditions, and pre-injury living arrangement, that were significantly associated with successful discharge, resulted in acceptable discrimination (area under the curve: 0.76, 95% confidence interval [CI]: 0.72-0.81). Higher scores on the FIM-M (odds ratio [OR]:1.07, 95% CI: 1.05-1.09) and FIM-C (OR: 1.05, 95% CI: 1.02-1.08) were associated with greater odds of successful discharge, whereas living alone vs with others (OR: 0.46, 95% CI: 0.30-0.71) and a greater number of chronic conditions (OR: 0.94, 95% CI: 0.90-0.99) were associated with lower odds of successful discharge. Conclusions: The results provide a parsimonious model for predicting successful discharge among older adults admitted to an IRF after a TBI-related hospitalization and provide clinically useful information to inform discharge planning.

Safety and Feasibility of Ultra-Restrictive Transfusion Protocol as a Blood-Preservation Strategy During Shortage Crises.

BACKGROUND: We hypothesized that implementation of new ultra-restrictive transfusion protocol in adult surgical intensive care units (SICU) was safe and feasible during pandemic-associated shortage crises. METHODS: Retrospective analysis two months pre- and post-implementation of ultra-restrictive transfusion protocol in March 2020 with hemoglobin cutoff of 6 g/dL (6.5 g/dL if ≥ 65 years old) for patients without COVID, active bleeding, or myocardial ischemia. RESULTS: We identified 16/93 and 27/168 patients PRE and POST meeting standard transfusion threshold (7 g/dL); within POST, 12 patients met ultra-restrictive cutoffs. There was no significant difference between PRE and POST in the rate of mortality, ischemic complications, or the number of transfusions per patient, however, the overall incidence of transfusion was lower in the POST group (7.1 vs 17.2%, p = 0.02). Patients received a mean (SD) of 4(3.8) and 2.4(1.5) PRBC transfusions pre- and post-implementation. Odds ratio of mortality in POST group was 0.62 (95%CI: 0.08-5.12) adjusted for age, sex, and SOFA score. CONCLUSIONS: Implementation of an ultra-restrictive transfusion protocol was feasible and effective as a blood- preservation strategy.

Lucky number 13: Association between center-specific chest wall stabilization volumes and patient outcomes.

BACKGROUND: Chest wall stabilization (CWS) improves outcomes for patients with chest wall injury (CWI). We hypothesized that patients treated at centers with higher annual CWS volumes experience superior outcomes. METHODS: A retrospective study of adults with acute CWI undergoing surgical stabilization of rib or sternal fractures within the 2019 Trauma Quality Improvement Program database, excluding those with 24-hour mortality or any Abbreviated Injury Scale body region of six, was conducted. Hospitals were grouped in quartiles by annual CWS volume. Our primary outcome was a composite of in-hospital mortality, ventilator-associated pneumonia, acute respiratory distress syndrome, sepsis, and unplanned intubation or intensive care unit readmission. Regression was controlled for age, sex, Injury Severity Scale, flail chest, medical comorbidities, and Abbreviated Injury Scale chest. We performed cut-point analysis and compared patient outcomes from high- and low-volume centers. RESULTS: We included 3,207 patients undergoing CWS at 430 hospitals with annual volumes ranging from 1 to 66. There were no differences between groups in age, sex, or Injury Severity Scale. Patients in the highest volume quartile (Q4) experienced significantly lower rates of the primary outcome (Q4, 14%; Q3, 18.4%; Q2, 17.4%; Q1, 22.1%) and significantly shorter hospital and intensive care unit lengths of stay. Q4 versus Q1 had lower adjusted odds of the primary outcome (odds ratio, 0.58; 95% confidence interval, 0.43-0.80). An optimal cut point of 12.5 procedures annually was used to define high- and low-volume centers. Patients treated at high-volume centers experienced significantly lower rates of the primary composite outcome, in-hospital mortality, and deep venous thrombosis with shorter lengths of stay and higher rates of home discharge. CONCLUSION: Center-specific CWS volume is associated with superior in-hospital patient outcomes. These findings support efforts to establish CWI centers of excellence. Further investigation should explore the impact of center-specific volume on patient-reported outcomes including pain and postdischarge quality of life. LEVEL OF EVIDENCE: Prognostic and Epidemiologic; Level III.

The association between household and neighborhood characteristics and COVID-19 related ICU admissions.

Introduction: Approaches to COVID-19 mitigation can be more efficiently delivered with a more detailed understanding of where the severe cases occur. Our objective was to assess which demographic, housing and neighborhood characteristics were independently and collectively associated with differing rates of severe COVID-19. Methods: A cohort of patients with SARS-CoV-2 in a single health system from March 1, 2020 to February 15, 2021 was reviewed to determine whether demographic, housing, or neighborhood characteristics are associated with higher rates of severe COVID-19 infections and to create a novel scoring index. Characteristics included proportion of multifamily homes, essential workers, and ages of the homes within neighborhoods. Results: There were 735 COVID-19 ICU admissions in the study interval which accounted for 61 percent of the state's ICU admissions for COVID-19. Compared to the general population of the state those admitted to the ICU with COVID-19 were disproportionately older, male sex, and were more often Black, Indigenous, People of Color. Patients disproportionately resided in neighborhoods with three plus unit multifamily homes, homes built before 1940, homes with more than one person to a room, homes of lower average value, and in neighborhoods with a greater proportion of essential workers. From this our COVID-19 Neighborhood Index value was comparatively higher for the ICU patients (61.1) relative to the population of Rhode Island (49.4). Conclusion: COVID-19-related ICU admissions are highly related to demographic, housing and neighborhood-level factors. This may guide more nuanced and targeted vaccine distribution plans and public health measures for future pandemics.

Comparison of Infectious Complications after Surgical Fixation versus Epidural Analgesia for Acute Rib Fractures.

Background: Surgical stabilization of rib fractures (SSRF) is associated with decreased mortality and respiratory complications. Patients who are not offered SSRF are often treated with epidural analgesia (EA) to reduce pain and improve pulmonary mechanics. We sought to compare infectious complications in patients undergoing either SSRF or EA. We hypothesized that infectious complications are equivalent between the two treatment groups. Patients and Methods: We performed a retrospective cohort study of adult trauma patients with acute rib fractures within the Trauma Quality Improvement Program (TQIP) 2017 dataset and used International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes to identify patients who underwent SSRF or EA. We excluded patients who received both treatments in the same admission. Our primary outcome was the development of sepsis. Secondary outcomes were specific infections including ventilator-associated pneumonia (VAP), catheter-associated urinary tract infection (CAUTI), and central line-associated blood stream infections (CLABSI). Multiple logistic regression analyses were used to adjust for age, injury severity score (ISS), chest Abbreviated Injury Scale (AIS), flail chest, traumatic brain injury (TBI), and comorbidities. Results: We identified 2,252 and 1,299 patients who underwent SSRF and EA, respectively. Patients with SSRF were younger with higher ISS and longer length of stay (LOS). There was no difference in mortality, however, SSRF had higher rate of sepsis (1.6% vs. 0.5%; p = 0.001), VAP (5.1% vs. 0.9%; p < 0.001), CAUTI (1.7% vs. 0.5%; p = 0.001), and CLABSI (0.2% vs. 0%; p = 0.05). On multiple regression, SSRF was associated with higher odds of sepsis (odds ratio [OR], 2.63; 95% confidence interval [CI], 1.04-6.63), CAUTI (OR, 2.96; 95% CI, 1.11-7.88), and VAP (OR, 3.24; 95% CI, 1.73-6.06). Among those who developed sepsis, there was no significant difference in mortality or LOS between groups. Conclusions: Despite no difference in mortality, SSRF was associated with increased risk of septic complications in patients with rib fractures compared to epidural analgesia. Identifying, and addressing, risk factors of sepsis in this patient population is a critical performance improvement process to optimize outcomes without increased adverse events.

Functional motor improvement during inpatient rehabilitation among older adults with traumatic brain injury.

BACKGROUND: Older adults comprise an increasingly large proportion of patients with traumatic brain injury (TBI) receiving care in inpatient rehabilitation facilities (IRF). However, high rates of comorbidities and evidence of declining preinjury health among older adults who sustain TBI raise questions about their ability to benefit from IRF care. OBJECTIVES: To describe the proportion of older adults with TBI who exhibited minimal detectable change (MDC) and a minimally clinically important difference (MCID) in motor function from IRF admission to discharge; and to identify characteristics associated with clinically meaningful improvement in motor function and better discharge functional status. DESIGN: This retrospective cohort study used Medicare administrative data probabilistically linked to the National Trauma Data Bank to estimate the proportion of patients whose motor function improved during inpatient rehabilitation and identify factors associated with meaningful improvement in motor function and motor function at discharge. SETTING: Inpatient rehabilitation facilities in the United States. PATIENTS: Fee-for-service Medicare beneficiaries with TBI. MAIN OUTCOME MEASURES: Minimal Detectable Change (MDC) and Minimally Clinically Important Difference (MCID) in the Functional Independence Measure motor (FIM-M) score from admission to discharge, and FIM-M score at IRF discharge. RESULTS: From IRF admission to discharge 84% of patients achieved the MDC threshold, and 68% of patients achieved the MCID threshold for FIM-M scores. Factors associated with a higher probability of achieving the MCID for FIM-M scores included better admission motor and cognitive function, lower comorbidity burden, and a length of stay longer than 10 days but only among individuals with lower admission motor function. Older age was associated with a lower FIM-M discharge score, but not the probability of achieving the MCID in FIM-M score. CONCLUSION: Older adults with TBI have the potential to improve their motor function with IRF care. Baseline functional status and comorbidity burden, rather than acute injury severity, should be used to guide care planning.

Predicting Anastomotic Leak After Elective Colectomy: Utility of a Modified Frailty Index.

BACKGROUND: Anastomotic leak is the most dreaded complication following colonic resection. While patient frailty is increasingly being recognized as a risk factor for surgical morbidity and mortality, the current colorectal body of literature has not assessed the relationship between frailty and anastomotic leak. OBJECTIVE: Evaluate the relationship between patient frailty and anastomotic leak as well as patient frailty and failure to rescue in patients who experienced an anastomotic leak. DESIGN: Retrospective cohort study. SETTING: American College of Surgeons National Surgical Quality Improvement Program Database from 2015 to 2017. PATIENTS: Patients with the diagnosis of colonic neoplasia undergoing an elective colectomy during the study time period. MAIN OUTCOME MEASURE: Anastomotic leak, failure to rescue. RESULTS: A total of 30,180 elective colectomies for neoplasia were identified. The leak rate was 2.9% (n = 880). Compared to nonfrail patients, frail patients were at increased odds of anastomotic leak (frailty score = 1: OR 1.34, 95% CI 1.10-1.63; frailty score = 2: OR 1.32, 95% CI 1.04-1.68; frailty score = 3: OR = 2.41, 95% CI 1.47-3.96). After an anastomotic leak, compared to nonfrail patient, a greater proportion of frail patients experienced mortality (3.4% vs 5.9%), septic shock (16.1% vs 21.0%), myocardial infarction (1.1% vs 2.9%), and pneumonia (6.8% vs 11.8%). Furthermore, the odds of mortality, septic shock, myocardial infarction, and pneumonia increased in frail patients with higher frailty scores. LIMITATIONS: Potential misclassification bias from lack of a strict definition of anastomotic leak and retrospective design of the study. CONCLUSION: Frail patients undergoing colectomy for colonic neoplasia are at increased risk of an anastomotic leak. Furthermore, once a leak occurs, they are more vulnerable to failure to rescue.

Impact of Direct Transport vs. Transfer on Out-of-Hospital Traumatic Cardiac Arrest.

BACKGROUND: Injured patients benefit from direct transport to a trauma center; however, it is unknown whether patients with traumatic out-of-hospital cardiac arrest (OHCA) benefit from initial resuscitation at the nearest emergency department (ED) if a trauma center is farther away. We hypothesized that patients with traumatic OHCA transported directly to a trauma center have less in-hospital mortality after initial resuscitation compared to those transferred from non-trauma centers. METHODS: We examined patients presenting with traumatic OHCA within our institutional trauma registry and the National Trauma Data Bank (NTDB) and excluded patients with ED mortality. Our primary outcome was all-cause mortality during index hospitalization; multiple logistic regression controlled for age, sex, injury severity score, mechanism of injury, signs of life, emergency surgery, and level I trauma center designation. RESULTS: We identified 271 and 1,138 adult patients with traumatic OHCA in our registry and the NTDB; 28% and 16% were transferred from another facility, respectively. Following initial resuscitation, patients transferred to a trauma center had higher in-hospital mortality than those transported directly in both our local and national cohorts (aOR: 2.27, 95%CI: 1.03-4.98, and aOR: 2.66, 95%CI: 1.35 - 5.26, respectively). DISCUSSION: Patients with traumatic OHCA transported directly to a trauma center may have increased survival to discharge compared to those transferred from another facility, even accounting for initial resuscitation. Further investigation should examine the impact of both physiologic and logistic factors including distance to trauma center, traffic, and weather patterns that may impact prehospital decision-making and destination selection.

Adding Infectious Insult to Traumatic Injury: The Impact of Infectious Complications in End-of-Life Decision Making.

Background: Trauma increases the risk for infection, but it is unknown how infection affects goals-of-care (GOC) decision making. We sought to determine how infections impact transition to comfort measures only (CMO), hypothesizing that infectious complications would expedite withdrawal of life-sustaining treatment (WOLST). Patients and Methods: We performed a retrospective review at a level-one trauma center over two years for adult patients without pre-existing advance directives who were made CMO with length of stay longer than one day. Demographics, injuries, and hospital course including infections and the GOC timeline were collected. Patients were divided on the basis of infection development, defined as an infectious complication requiring antibiotics or more invasive intervention, with subgroup analysis comparing those with single versus multiple infections. The primary end point was time to death or discharge. Results: Two hundred thirty-two patients met inclusion criteria and 72 developed an infection. Pneumonia was the most common infection (53.8%). Although those in the infection group had no substantial difference in demographics or comorbidities, they had higher emergency department Glasgow Coma Scale (GCS; 14 vs. 13), lower rate of head injury (28.6 vs. 49%), and higher time to death or discharge (12 vs. 2 days). Goals-of-care discussions were initiated later based on time to first family meeting (7 vs. 1 days), most occurring after the first infection. Subsequent analysis showed that versus those with a single infection (n = 38), those with multiple infections (n = 34) had a higher time to death or discharge (16.5 vs. 10.5 days) despite no difference in demographics, comorbidities, or trauma severity. Time to first family meeting was longer (8.5 vs. 4.5 days) with most occurring after the first infection. Conclusions: We did not find that development of an infection shortens time to WOLST. The increased time to death or discharge in the setting of multiple infections and similar patient populations may be a marker of provider approach to GOC plus family beliefs. Infectious complications play an uncertain role in end-of-life discussions after trauma.

Time to Head Computed Tomography Protocol in Traumatic Brain Injury: A Quality Improvement Metric.

BACKGROUND: Early identification of traumatic brain injury (TBI) with head CT HCT should expedite operative decision-making and improve outcome. We aimed to determine whether an early HCT protocol in TBI patients would improve outcome. METHODS: A multidisciplinary protocol to obtain an HCT within 30 minutes from arrival for patients with GCS ≤ 13 was instituted on 1/1/2015. Our trauma registry was queried for patients evaluated between 3/2012 and 12/2015. Outcomes included compliance with protocol and in-hospital mortality. RESULTS: 346 patients presented with GCS ≤ 13. Patients PRE- (n=264) and POST-protocol (n=82) were similar in demographic and physiologic characteristics. Time to HCT was lower (35 vs. 77 min; p<0.001). POST-protocol had lower odds of mortality (OR 0.65, 95% CI 0.43-0.99) adjusting for age, gender, ISS and GCS. CONCLUSION: Implementing a protocol of early HCT for TBI optimized performance of the trauma team. Time to HCT could serve as a quality metric in TBI.

Decision Making Regarding Trauma Patients in Rhode Island who Present on Anticoagulants and Antiplatelet Agents: A Multidisciplinary and Collaborative Approach.

OBJECTIVES: Use of anticoagulant and antiplatelet medications (AAMs) is increasing significantly with our growing population of older adults. AAMs worsen outcomes in trauma patients. Our goal was to improve collaboration between trauma and outpatient providers and to improve safety in making decisions on anticoagulant and antiplatelet medications(AAMs) after injuries. DESIGN: A risk management initiative. SETTING AND PARTICIPANTS: Patients that suffered traumatic injury while on anticoagulation or antiplatelets medications at a level I university trauma center. METHODS: IRB approval was obtained to review records for medications, demographics, mechanism and type of injury, and indication for preinjury AAM use. Inpatient trauma team providers contacted the primary prescriber. A collaborative decision was made regarding AAM plans. RESULTS: One hundred and five patients, mean age 79 years, were followed. The three most common AAMs were warfarin (69 patients), clopidogrel (24), and Factor Xa inhibitors (16). Atrial fibrillation was the most common indication for AAMs (70 patients), venous thrombosis (14) and TIA/CVA (11). Falls were the most frequent injury mechanism, 79.4%. Soft tissue hematomas (27.4%), TBI (16%), and pelvic fractures (12.3%) were the most common injuries. In 56.6% AAMs were held until follow-up, 31.1% had AAMs resumed at discharge, and AAMs were held indefinitely in 12.3%. Patients discharged to home versus facility (37 vs 18% p<0.05), <75 years of age (47 vs 27% p<0.05) were more likely to have AAMs resumed at discharge. Patients who suffered falls versus MVC mechanism were less likely to have AAMs resumed at discharge (28 vs 82% p<0.05). CHA2DS2-VASc scores were similar between decision groups. CONCLUSIONS AND IMPLICATIONS: This is the first description of mandatory communication between trauma and outpatient providers to guide decision making on AAMs after injury. Efforts should be made to determine if this mitigates risk by following patients longterm. This communication should become standard for a population that is often elderly, frail, and at risk of repeat injuries.

Successful Community Discharge Among Older Adults With Traumatic Brain Injury in Skilled Nursing Facilities.

OBJECTIVE: To identify patient, injury, and functional status characteristics associated with successful discharge to the community following a skilled nursing facility (SNF) stay among older adults hospitalized following traumatic brain injury (TBI). SETTING: Skilled nursing facilities. PARTICIPANTS: Medicare fee-for-service beneficiaries admitted to an SNF after hospitalization for TBI. DESIGN: Retrospective cohort study using Medicare administrative data merged with the National Trauma Data Bank using a multilayered Bayesian record linkage approach. MAIN OUTCOME MEASURE: Successful community discharge: discharged alive within 100 days of SNF admission and remaining in the community for 30 days or more without dying or admission to a healthcare facility. RESULTS: Medicaid enrollment, incontinence, decreased independence with activities of daily living, and cognitive impairment were associated with lower odds of successful discharge, whereas race "other" was associated with higher odds of successful discharge. Injury factors including worse injury severity (Glasgow Coma Scale and Abbreviated Injury Scale scores) and fall-related injury mechanism were not associated with successful discharge. CONCLUSION: Among older adults with TBI who discharge to an SNF, sociodemographic and functional status characteristics are associated with successful discharge and may be useful to clinicians for discharge planning. Acute injury severity indices may have limited utility in predicting discharge disposition once a patient is admitted to an SNF for post-acute care.

Avoiding Cribari gridlock 2: The standardized triage assessment tool outperforms the Cribari matrix method in 38 adult and pediatric trauma centers.

OBJECTIVES: The Cribari Matrix Method (CMM) is the current standard to identify over/undertriage but requires manual trauma triage reviews to address its inadequacies. The Standardized Triage Assessment Tool (STAT) partially emulates triage review by combining CMM with the Need For Trauma Intervention, an indicator of major trauma. This study aimed to validate STAT in a multicenter sample. METHODS: Thirty-eight adult and pediatric US trauma centers submitted data for 97,282 encounters. Mixed models estimated the effects of overtriage and undertriage versus appropriate triage on the odds of complication, odds of discharge to a continuing care facility, and differences in length of stay for both CMM and STAT. Significance was assessed at p <0.005. RESULTS: Overtriage (53.49% vs. 30.79%) and undertriage (17.19% vs. 3.55%) rates were notably lower with STAT than with CMM. CMM and STAT had significant associations with all outcomes, with overtriages demonstrating lower injury burdens and undertriages showing higher injury burdens than appropriately triaged patients. STAT indicated significantly stronger associations with outcomes than CMM, except in odds of discharge to continuing care facility among patients who received a full trauma team activation where STAT and CMM were similar. CONCLUSIONS: This multicenter study strongly indicates STAT safely and accurately flags fewer cases for triage reviews, thereby reducing the subjectivity introduced by manual triage determinations. This may enable better refinement of activation criteria and reduced workload.

Unjustified Administration in Liberal Use of Tranexamic Acid in Trauma Resuscitation.

BACKGROUND: Early administration of tranexamic acid (TXA) has been widely implemented for the treatment of presumed hyperfibrinolysis in hemorrhagic shock. We aimed to characterize the liberal use of TXA and whether unjustified administration was associated with increased venous thrombotic events (VTEs). METHODS: We identified injured patients who received TXA between January 2016 and January 2018 by querying our Level 1 trauma center's registry. We retrospectively reviewed medical records and radiologic images to classify whether patients had a hemorrhagic injury that would have benefited from TXA (justified) or not (unjustified). RESULTS: Ninety-five patients received TXA for traumatic injuries, 42.1% were given by emergency medical services. TXA was considered unjustified in 35.8% of the patients retrospectively and in 52% of the patients when given by emergency medical services. Compared with unjustified administration, patients in the justified group were younger (47.6 versus 58.4; P = 0.02), more hypotensive in the field (systolic blood pressure: 107 ± 31 versus 137 ± 32 mm Hg; P < 0.001) and in the emergency department (systolic blood pressure: 97 ± 27 versus 128 ± 27; P < 0.001), and more tachycardic in emergency department (heart rate: 99 ± 29 versus 88 ± 19; P = 0.04). The justified group also had higher injury severity score (median 24 versus 11; P < 0.001), was transfused more often (81.7% versus 20.6%; P < 0.001), and had higher in-hospital mortality (39.3% versus 2.9%; P < 0.001), but there was no difference in the rate of VTE (8.2% versus 5.9%). CONCLUSIONS: Our results highlight a high rate of unjustified administration, especially in the prehospital setting. Hypotension and tachycardia were indications of correct use. Although we did not observe a difference in VTE rates between the groups, though, our study was underpowered to detect a difference. Cautious implementation of TXA in resuscitation protocols is encouraged in the meantime. Nonetheless, adverse events associated with unjustified TXA administration should be further evaluated.

Simulation-Based Examination of Arterial Line Insertion Method Reveals Interdisciplinary Practice Differences.

INTRODUCTION: Arterial cannulation is frequently performed on intensive care unit (ICU) and operating room patients; a 1% complication rate has been reported. Investigators applied simulation to study clinical providers' arterial catheter (AC) insertion performance and to assess for interdisciplinary and intradisciplinary variation that may contribute to complications. METHODS: Anesthesia, medical critical care, and surgical critical care providers with AC insertion experience were enrolled at 2 academic hospitals. Each subject completed a simulated AC insertion on an in situ task trainer. Using a Delphi-derived checklist that incorporated published recommendations, expert opinion, and institutional requirements, 2 investigators completed offline video reviews to compare subjects' technical performance. RESULTS: Ten anesthesia, 11 medical ICU (MICU, 1 excluded), and 10 surgical ICU (SICU) subjects with significant between-group differences in training level and AC insertion experience were enrolled for 2 years. Differences in procedural planning, equipment preparation, and patient preparation steps did not attain significance across groups except for anesthesia participants using only ad hoc AC kits, and MICU and SICU subjects preferentially using commercial kits (P < 0.001). Time-outs were completed by 1 anesthesia subject, 5 MICU subjects, and 4 SICU subjects (P = 0.29, NS). For proceduralist preparation steps, fewer anesthesiology subjects donned gowns (P < 0.001). Only MICU subjects used ultrasound guidance (P = 0.0053), and only MICU (100%) and SICU (100%) subjects sutured ACs in place. Overall observance of sterile technique was similar across groups at 70% to 100% (P = 0.32). CONCLUSIONS: Simulated AC insertions revealed procedural performance variability that may derive from individual provider differences, discipline-based practice parameters, and setting-specific cultural factors.
