RESUMO
PURPOSE: To investigate management trends for American Association for the Surgery of Trauma (AAST) grade V renal trauma with focus on non-operative management. METHODS: We used prospectively collected data as part of the Multi-institutional Genito-Urinary Trauma Study (MiGUTS). We included patients with grade V renal trauma according to the AAST Injury Scoring Scale 2018 update. All cases submitted by participating centers with radiology images available were independently reviewed to confirm renal trauma grade. Management was classified as expectant, conservative (minimally invasive, endoscopic or percutaneous procedures), or operative (renal-related surgery). RESULTS: Eighty patients were included, 25 of whom had complete imaging and had independent confirmation of AAST grade V renal trauma. Median age was 35 years (Interquartile range (IQR) 25-50) and 23 (92%) had blunt trauma. Ten patients (40%) were managed operatively with nephrectomy. Conservative management was used in nine patients (36%) of which six received angioembolization and three had a stent or drainage tube placed. Expectant management was followed in six (24%) patients. Transfusion requirements were progressively higher with groups requiring more aggressive treatment, and injury characteristics differed significantly across management groups in terms of hematoma size and laceration size. Vascular contrast extravasation was more likely in operatively managed patients though a statistically significant association was not found. CONCLUSION: Successful use of nonoperative management for grade V injuries is used for a substantial subset of patients. Lower transfusion requirement and less severe injury radiologic phenotype appear to be important characteristics delineating this group.

BACKGROUND: Assessment of patient satisfaction is central to understanding and improving system performance with the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) national standard survey. However, no large, multi-institutional study exists, which examines the role of nurses in trauma patient satisfaction. OBJECTIVE: To assess the impact of nurses on trauma patient satisfaction. METHODS: This retrospective, descriptive study of Level I-IV trauma centers in a multistate hospital system evaluated patients 18 years and older admitted with at least an overnight stay. Data were obtained electronically for patients discharged in 2018-2019 who returned an HCAHPS survey. Surveys were linked by an honest broker to demographic and injury data from the trauma registry, and then anonymized prior to analysis. Patients were categorized as "trauma" per the National Trauma Data Standard (NTDS) definition or as "medical" or "surgical" per the HCAHPS definition. RESULTS: Of 112,283 surveys from 89 trauma centers, "trauma" patients (n = 5,126) comprised 4.6%, "surgical" 39.0% (n = 43,763), and "medical" 56.5% (n = 63,394). Nurses had an overwhelming impact on "trauma" patient satisfaction, accounting for 63.9% (p < .001) of the variation (adjusted R2) in the overall score awarded the institution-larger than for "surgery" (59.6%; p < .001) or "medical" (58.4%; p < .001) patients. The most important individual domain contributor to the overall rating of a facility was "nursing communication." CONCLUSIONS: The magnitude of the effect of trauma nurses was noteworthy, with their communication ability being the single biggest driver of institutional ratings. These data provide insight for future performance benchmark development and emphasize the critical impact of trauma nurses on the trauma patient experience.

BACKGROUND: Blunt cerebrovascular injuries (BCVIs) are associated with long-term neurological effects. The first-line treatment for BCVIs is antithrombotics, but consensus on the optimal choice and timing of treatment is lacking. METHODS: This was a retrospective study on patients aged at least 18 years admitted to 6 level 1 trauma centers between 1/1/2014 and 12/31/2017 with grade 1-4 BCVI and treated with antithrombotics. Differences in treatment practices were examined across the 6 centers. The primary outcome was ischemic stroke, and secondary outcomes were related to bleeding complications: blood transfusion and intracranial hemorrhage (ICH). Treatment characteristics examined were time to diagnosis and first computerized tomography angiography, time of total treatment course, time on each antithrombotic (anticoagulants, antiplatelets, combination), time from hospital arrival to antithrombotic initiation, and treatment interruption, i.e., treatment halted for a surgical procedure and restarted postoperatively. Chi-square, Fisher exact, Spearman's rank-order correlation, Wilcoxon rank-sum, Kruskal-Wallis, and Cox proportional hazards models with time-varying covariates were used to evaluate associations with the outcomes. RESULTS: A total of 189 patients with BCVI were included. The median (IQR) time from arrival to antithrombotic initiation was 27 (8-61) hours, and 28% of patients had treatment interrupted. The ischemic stroke rate was 7.5% (nâ¯=â¯14), with most strokes (64%, nâ¯=â¯9) occurring between arrival and treatment initiation. Treatment interruption was associated with ischemic stroke (75% of patients with stroke had an interruption versus 24% of patients with no stroke; P < .01). Time on anticoagulants was not associated with ischemic stroke (Pâ¯=â¯.78), transfusion (Pâ¯=â¯.43), or ICH (Pâ¯=â¯.96). Similarly, time on antiplatelets (Pâ¯=â¯.54, Pâ¯=â¯.65, Pâ¯=â¯.60) and time on combination therapy (Pâ¯=â¯.96, Pâ¯=â¯.38, Pâ¯=â¯.57) were not associated with these outcomes. CONCLUSIONS: The timing and consistency of antithrombotic administration are critical in preventing adverse outcomes in patients with BCVI. Most ischemic strokes in this study population occurred between arrival and antithrombotic initiation, representing events that may potentially be intervened upon by earlier treatment. Future studies should examine the safety of continuing treatment through surgical procedures.

Activation of the innate immune system involves a series of events designed to counteract the initial insult followed by the clearance of debris and promotion of healing. Aberrant regulation can lead to systemic inflammatory response syndrome, multiple organ failure, and chronic inflammation. A better understanding of the innate immune response may help manage complications while allowing for proper immune progression. In this study, the ability of several classes of anti-inflammatory drugs to affect LPS-induced cytokine and prostaglandin release from peripheral blood mononuclear cells (PBMC) was evaluated. PBMC were cultured in the presence of dexamethasone (DEX), ibuprofen (IBU), and the low molecular weight fraction of 5% albumin (LMWF5A) followed by stimulation with LPS. After 24 h, TNFα, PGE2, and 15d-PGJ2 release was determined by ELISA. Distinct immunomodulation patterns emerged following LPS stimulation of PBMC in the presence of said compounds. DEX, a steroid with strong immunosuppressive properties, reduced TNFα, PGE2, and 15d-PGJ2 release. IBU caused significant reduction in prostaglandin release while TNFα release was unchanged. An emerging biologic with known anti-inflammatory properties, LMWF5A, significantly reduced TNFα release while enhancing PGE2 and 15d-PGJ2 release. Incubating LMWF5A together with IBU negated this observed increased prostaglandin release without affecting the suppression of TNFα release. Additionally, LMWF5A caused an increase in COX-2 transcription and translation. LMWF5A exhibited a unique immune modulation pattern in PBMC, disparate from steroid or NSAID administration. This enhancement of prostaglandin release (specifically 15d-PGJ2), in conjunction with a decrease in TNFα release, suggests a switch that favors resolution and decreased inflammation.

Emergent ambulance transportation is associated with increased risk of collision, injury, and death for EMS professionals, patients, and the general public. Time saved using lights and siren (L&S) is typically small, and often provides minimal clinical benefit. Our objective was to investigate the frequency of L&S transports, describe the precision of the decision to employ L&S to predict the need for a time critical hospital intervention (TCHI) within 15 minutes of hospital arrival, identify clinical predictors of a TCHI, and compare clinical outcomes in patients transported by Emergency Medical Services (EMS) with and without L&S in a trauma-specific population. EMS patient care reports and trauma registry data were retrospectively reviewed for trauma patients consecutively transported from the field by three EMS agencies to three trauma centers within urban and suburban settings over a two-year period. TCHIs were collaboratively developed by the study team. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were utilized to report the precision of the decision to employ L&S to predict the need of a TCHI. Univariate and multivariate analyses determined predictors of a TCHI and compared clinical outcomes. 2,091 patients were included in the study. Of the 19.8% of patients transported with L&S, 22.9% received a TCHI. The most common TCHI was airway or respiratory procedures (87.2% of all TCHI's). The sensitivity and specificity of L&S to predict the need for a TCHI was 87.2% (95% CI 79.4-92.8) and 84.0% (95% CI 82.2-85.5), respectively. PPV was 23.0% (95% CI 23.53-38.01); NPV was 99.2% (95% CI 98.6-99.6). L&S was predictive for the need for a TCHI (p < 0.001), as was abnormal Glasgow Coma Score (p < 0.001), abnormal systolic blood pressure and age (p < 0.05 for all). Among patients that received a TCHI, over a third that were transported with L&S (36.8%) expired, compared with two of 14 patients (14.3%) not transported L&S. EMS professionals in this study demonstrated a high ability to discern which trauma patients did not require L&S. Nevertheless, L&S transport resulted in a TCHI less than one quarter of the time, suggesting an opportunity for further reduction of L&S transports in trauma patients.

The innate immune system is increasingly being recognized as a critical component in osteoarthritis (OA) pathophysiology. An ex vivo immunoassay utilizing human peripheral blood mononuclear cells (PBMC) was developed in order to assess the OA anti-inflammatory properties of the low molecular weight fraction (<5 kDa) of commercial human serum albumin (LMWF5A). PBMC from various donors were pre-incubated with LMWF5A before LPS stimulation. TNFα release was measured by ELISA in supernatants after an overnight incubation. A ≥ 30% decrease in TNFα release was observed. This anti-inflammatory effect is potentially useful in assessing potency of LMWF5A for the treatment of OA.

Background: Hospice and palliative care (PC) utilization is increasing in geriatric inpatients, but limited research exists comparing rates among trauma, surgical and medical specialties. The goal of this study was to determine whether there are differences among these three groups in rates of hospice and PC utilization. Methods: Patients from Centers for Medicare & Medicaid Services (CMS) Inpatient Standard Analytical Files for 2016-2020 aged ≥65 years were analyzed. Patients with a National Trauma Data Standard-qualifying ICD-10 injury code with abbreviated injury score ≥2 were classified as 'trauma'; the rest as 'surgical' or 'medical' using CMS MS-DRG definitions. Patients were classified as having PC if they had an ICD-10 diagnosis code for PC (Z51.5) and as hospice discharge (HD) if their hospital disposition was 'hospice' (home or inpatient). Use proportions for specialties were compared by group and by subgroups with increasing risk of poor outcome. Results: There were 16M hospitalizations from 1024 hospitals (9.3% trauma, 26.3% surgical and 64.4% medical) with 53.7% women, 84.5% white and 38.7% >80 years. Overall, 6.2% received PC and 4.1% a HD. Both rates were higher in trauma patients (HD: 3.6%, PC: 6.3%) versus surgical patients (HD: 1.5%, PC: 3.0%), but lower than in medical patients (HD: 5.2%, PC: 7.5%). PC rates increased in higher risk patient subgroups and were highest for inpatient HD. Conclusions: In this large study of Medicare patients, HD and PC rates varied significantly among specialties. Trauma patients had higher HD and PC utilization rates than surgical, but lower than medical. The presence of comorbidities, frailty and/or severe traumatic brain injury (in addition to advanced age) may be valuable criteria in selection of trauma patients for hospice and PC services. Further studies are needed to inform the most efficient use of hospice and PC resources, with particular focus on both timing and selection of subgroups most likely to benefit from these valuable yet limited resources. Level of evidence: Level III, therapeutic/care management.
RESUMO
BACKGROUND: This study updates the American Association for the Surgery of Trauma (AAST) Organ Injury Scale (OIS) for renal trauma using evidence-based criteria for bleeding control intervention. METHODS: This was a secondary analysis of a multicenter retrospective study including patients with high-grade renal trauma from seven level 1 trauma centers from 2013 to 2018. All eligible patients were assigned new renal trauma grades based on revised criteria. The primary outcome used to measure injury severity was intervention for renal bleeding. Secondary outcomes included intervention for urinary extravasation, units of packed red blood cells transfused within 24 hours, and mortality. To test the revised grading system, we performed mixed-effect logistic regression adjusted for multiple baseline demographic and trauma covariates. We determined the area under the curve (AUC) to assess accuracy of predicting bleeding interventions from the revised grading system and compared this to 2018 AAST OIS. RESULTS: Based on the 2018 OIS grading system, we included 549 patients with AAST grades III to V injuries and computed tomography scans (III, 52% [n = 284]; IV, 45% [n = 249]; and V, 3% [n = 16]). Among these patients, 89% experienced blunt injury (n = 491), and 12% (n = 64) underwent intervention for bleeding. After applying the revised grading criteria, 60% (n = 329) of patients were downgraded, and 4% (n = 23) were upgraded; 2.8% (n = 7) downgraded from grade V to IV, and 69.5% (n = 173) downgraded from grade IV to III. The revised renal trauma grading system demonstrated improved predictive ability for bleeding interventions (2018 AUC, 0.805; revised AUC, 0.883; p = 0.001) and number of units of packed red blood cells transfused. When we removed urinary injury from the revised system, there was no difference in its predictive ability for renal hemorrhage intervention. CONCLUSION: A revised renal trauma grading system better delineates the need for hemostatic interventions than the current AAST OIS renal trauma grading system. LEVEL OF EVIDENCE: Diagnostic Test/Criteria; Level III.

BACKGROUND: Anti-inflammatory effects of tranexamic acid (TXA) in reducing trauma endotheliopathy may protect from acute lung injury. Clinical data showing this benefit in trauma patients is lacking. We hypothesized that TXA administration mitigates pulmonary complications in penetrating trauma patients. MATERIALS AND METHODS: This is a post-hoc analysis of a multicenter, prospective, observational study of adults (18+ years) with penetrating torso and/or proximal extremity injury presenting at 25 urban trauma centers. Tranexamic acid administration in the prehospital setting or within three hours of admission was examined. Participants were propensity matched to compare similarly injured patients. The primary outcome was development of pulmonary complication (ARDS and/or pneumonia). RESULTS: A total of 2382 patients were included, and 206 (8.6%) received TXA. Of the 206, 93 (45%) received TXA prehospital and 113 (55%) received it within three hours of hospital admission. Age, sex, and incidence of massive transfusion did not differ. The TXA group was more severely injured, more frequently presented in shock (SBP < 90 mmHg), developed more pulmonary complications, and had lower survival (P < 0.01 for all). After propensity matching, 410 patients remained (205 in each cohort) with no difference in age, sex, or rate of shock. On logistic regression, increased emergency department heart rate was associated with pulmonary complications. Tranexamic acid was not associated with different rate of pulmonary complications or survival on logistic regression. Survival was not different between the groups on logistic regression or propensity score-matched analysis. CONCLUSIONS: Tranexamic acid administration is not protective against pulmonary complications in penetrating trauma patients.
RESUMO
BACKGROUND: Since the patient's skin is a major source of pathogens that cause surgical-site infection, optimization of preoperative skin antisepsis may decrease postoperative infections. We hypothesized that preoperative skin cleansing with chlorhexidine-alcohol is more protective against infection than is povidone-iodine. METHODS: We randomly assigned adults undergoing clean-contaminated surgery in six hospitals to preoperative skin preparation with either chlorhexidine-alcohol scrub or povidone-iodine scrub and paint. The primary outcome was any surgical-site infection within 30 days after surgery. Secondary outcomes included individual types of surgical-site infections. RESULTS: A total of 849 subjects (409 in the chlorhexidine-alcohol group and 440 in the povidone-iodine group) qualified for the intention-to-treat analysis. The overall rate of surgical-site infection was significantly lower in the chlorhexidine-alcohol group than in the povidone-iodine group (9.5% vs. 16.1%; P=0.004; relative risk, 0.59; 95% confidence interval, 0.41 to 0.85). Chlorhexidine-alcohol was significantly more protective than povidone-iodine against both superficial incisional infections (4.2% vs. 8.6%, P=0.008) and deep incisional infections (1% vs. 3%, P=0.05) but not against organ-space infections (4.4% vs. 4.5%). Similar results were observed in the per-protocol analysis of the 813 patients who remained in the study during the 30-day follow-up period. Adverse events were similar in the two study groups. CONCLUSIONS: Preoperative cleansing of the patient's skin with chlorhexidine-alcohol is superior to cleansing with povidone-iodine for preventing surgical-site infection after clean-contaminated surgery.

Open fractures are at high risk of infection because of exposure of bone and tissue to the environment. Initiation of intravenous antibiotics is recommended within 1 hour of hospital arrival, although the presence of other severe injuries may lead to delays in fracture management. This retrospective study of adult patients with open long-bone fractures admitted to six level 1 trauma centers between January 1, 2018, and December 31, 2019, aimed to examine adherence to antibiotic recommendations. Associations between receiving recommendation-adherent antibiotics and patient and injury characteristics were investigated univariately and in adjusted regression analyses. The most common fracture locations among the 404 patients included were the tibia (43%) and fibula (26%). Fifty-eight percent of patients received recommendation-adherent antibiotics. After adjustment, patient demographics, comorbidities, cause of injury, and overall injury severity did not show significant associations with adherence to recommendations. Concomitant serious abdominal (adjusted odds ratio [AOR]=0.44) and spinal injuries (AOR=0.23) were associated with lower odds of receiving recommendation-adherent antibiotics. Additionally, fractures of certain locations were associated with increased odds of adherence (humerus: AOR=2.78; fibula: AOR=1.64), as were type 3 fractures (AOR=1.55). The overall infection rate was 4%, and adherence to antibiotic recommendations was not associated with infection (3% vs 5% for nonadherent, P=.34). Results suggest that although full recommendation adherence was somewhat low among this patient population, certain injury characteristics were predictive of adherence rates. Current antibiotic recommendations may benefit from consideration of how antibiotic initiation may fit into the prioritization of injury management, especially in patients with polytrauma with other severe injuries.

The objective of this study was to quantify nation-wide interhospital variation in neurosurgical intervention risk by intracranial hemorrhage (ICH) type in the setting of mild traumatic brain injury (mTBI). This was a retrospective cohort study of adult (≥18 years) trauma patients included in the National Trauma Data Bank from 2007 to 2019 with an emergency department Glasgow Coma Scale score 13-15, diagnosed ICH, no skull fracture. The primary outcome was neurosurgical intervention. Interhospital variation was assessed by examining the best linear unbiased predictors (BLUPs) obtained from mixed-effects logistic regression with random slopes and intercepts for hospitals and covariates for time and 14 demographic, injury, and hospital characteristics; one model per ICH type. Intercept BLUPs are estimates of how different each hospital is from the average hospital (after covariate adjustment). The study population included 49,220 (7%) neurosurgical interventions among 666,842 patients in 1060 hospitals. In 2019, after adjusting for patient case-mix and hospital characteristics, the percentage of hospitals with hemorrhage-specific neurosurgical intervention risk significantly different from the average hospital was as follows: isolated unspecified hemorrhage (0% of 995 hospitals); isolated contusion/laceration (0.54% of 929); isolated epidural hemorrhage (0.39% of 778); isolated subarachnoid hemorrhage (0.10% of 1002); multiple hemorrhages (2.49% of 963); and isolated subdural hemorrhage (16.25% of 1028). In the setting of mTBI, isolated subdural hemorrhages were the only ICH type to have considerable interhospital variability. Causes for this significant variation should be elucidated and might include changing hemorrhage characteristics and practice patterns over time.
RESUMO
There have been large changes over the past several decades to patient demographics in those presenting with mild traumatic brain injury (mTBI) with intracranial hemorrhage (ICH; complicated mTBI) with the potential to affect the use of neurosurgical interventions. The objective of this study was to characterize long-term trends of neurosurgical interventions in patients with complicated mTBI using 13 years of the National Trauma Data Bank (NTDB). This was a retrospective cohort study of adult (≥18 years) trauma patients included in the NTDB from 2007 to 2019 who had an emergency department Glasgow Coma Scale score 13-15, an intracranial hemorrhage (ICH), and no skull fracture. Neurosurgical intervention time trends were quantified for each ICH type using mixed-effects logistic regression with random slopes and intercepts for hospitals, as well as covariates for time and 14 demographic, injury, and hospital characteristics. In total, 666,842 ICH patients across 1060 hospitals were included. The four most common hemorrhages were isolated subdural hemorrhage (36%), isolated subarachnoid hemorrhage (24%), multiple hemorrhage types (24%), and isolated unspecified hemorrhages (9%). Overall, 49,220 (7%) patients received a neurosurgical intervention. After adjustment, the odds of neurosurgical intervention significantly decreased every 10 years by the following odds ratios (odds ratio [95% confidence interval]): 0.85 [0.78, 0.93] for isolated subdural, 0.63 [0.51, 0.77] for isolated subarachnoid, 0.50 [0.41, 0.62] for isolated unspecified, and 0.79 [0.73, 0.86] for multiple hemorrhages. There were no significant temporal trends in neurosurgical intervention odds for isolated epidural hemorrhages (0.87 [0.68, 1.12]) or isolated contusions/lacerations (1.03 [0.75, 1.41]). In the setting of complicated mTBI, the four most common ICH types were associated with significant declines in the odds of neurosurgical intervention over the past decade. It remains unclear whether changing hemorrhage characteristics or practice patterns drove these trends.
RESUMO
Background: Small bowel obstruction (SBO) is a common disorder managed by surgeons. Despite extensive publications and management guidelines, there is no universally accepted approach to its diagnosis and management. We conducted a survey of acute care surgeons to elucidate their SBO practice patterns.Methods: A self-report survey of SBO diagnosis and management practices was designed and distributed by email to AAST surgeons who cared for adult SBO patients. Responses were analyzed with descriptive statistics and Chi-square test of independence at α = .05.Results: There were 201 useable surveys: 53% ≥ 50 years, 77% male, 77% at level I trauma centers. Only 35.8% reported formal hospital SBO management guidelines. Computed tomography (CT) scan was the only diagnostic exam listed as "essential" by the majority of respondents (82.6%). Following NG decompression, 153 (76.1%) would "always/frequently" administer a water-soluble contrast challenge (GC). There were notable age differences in approach. Compared to those ≥50 years, younger surgeons were less likely to deem plain abdominal films as "essential" (16.0% vs 40.2%; P < .01) but more likely to require CT scan (88.3% vs 77.6%; P = .045) for diagnosis and to "always/frequently" administer GC (84.0% vs 69.2%; P < .01). Younger surgeons used laparoscopy "frequently" more often than older surgeons (34.0% vs 21.5%, P = .05).Discussion: There is significant variation in diagnosis and management of SBO among respondents in this convenience sample, despite existing PMGs. Novel age differences in responses were observed, which prompts further evaluation. Additional research is needed to determine whether variation in practice patterns is widespread and affects outcomes.

BACKGROUND: Few large investigations have addressed the prevalence of COVID-19 infection among trauma patients and impact on providers. The purpose of this study was to quantify the prevalence of COVID-19 infection among trauma patients by timing of diagnosis, assess nosocomial exposure risk, and evaluate the impact of COVID-19 positive status on morbidity and mortality. METHODS: Registry data from adults admitted 4/1/2020-10/31/2020 from 46 level I/II trauma centers were grouped by: timing of first positive status (Day 1, Day 2-6, or Day ≥ 7); overall Positive/Negative status; or Unknown if test results were unavailable. Groups were compared on outcomes (Trauma Quality Improvement Program complications) and mortality using univariate analysis and adjusted logistic regression. RESULTS: There were 28 904 patients (60.7% male, mean age: 56.4, mean injury severity score: 10.5). Of 13 274 (46%) patients with known COVID-19 status, 266 (2%) were Positive Day 1, 119 (1%) Days 2-6, 33 (.2%) Day ≥ 7, and 12 856 (97%) tested Negative. COVID-19 Positive patients had significantly worse outcomes compared to Negative; unadjusted comparisons showed longer hospital length of stay (10.98 vs 7.47;P < .05), higher rates of intensive care unit (57.7% vs 45.7%; P < .05) and ventilation use (22.5% vs 16.9%; P < .05). Adjusted comparisons showed higher rates of acute respiratory distress syndrome (1.7% vs .4%; P < .05) and death (8.1% vs 3.4%; P < .05). CONCLUSIONS: This multicenter study conducted during the early pandemic period revealed few trauma patients tested COVID-19 positive, suggesting relatively low exposure risk to care providers. COVID-19 positive status was associated with significantly higher mortality and specific morbidity. Further analysis is needed with consideration for care guidelines specific to COVID-19 positive trauma patients as the pandemic continues.

BACKGROUND: The relationship between drug use and traumatic injury is well documented, yet only a small proportion of patients are biochemically tested for cannabis and other substances. The study objective was to determine whether patient self-report can be used as a proxy for biochemical drug testing following traumatic injury. METHODS: This study was a secondary analysis that included 320 patients admitted to four level I trauma centers in Colorado and Texas, primarily involved in motor vehicle crash (89%). If performed, biochemical testing was collected via urine toxicology screen ("tox screen") for cannabis, amphetamines, barbiturates, cocaine, opiates, PCP, and benzodiazepines. All patients were screened for self-reported current drug use, which was evaluated for any drug and specifically for cannabis use. Analyses used to compare results of self-reported drug use and tox screen included sensitivity, specificity, positive, and negative predictive values, and percent agreement. RESULTS: Among 320 patients, 23% (n = 75) self-reported drug use; cannabis was the most frequently reported drug (n = 63). A tox screen was performed in 59% of patients (n = 190); the proportion of patients who had a tox screen was similar for those self-reporting drug use (60.0%) to those who denied using drugs (59.2%), p = 0.90. Among patients who had a tox screen performed, 18% (n = 35) tested positive for any drug, 12% (n = 22) tested positive for THC, and 7% (n = 13) tested positive for opiates. The percent agreement was 80% for any drug and 81% for cannabis. The specificity was 84-85%, indicating a high likelihood that a patient will not have a positive tox screen if they do not report using drugs. Negative predictive values were 90-95%, indicating a negative self-report correctly identified nearly all patients testing negative on tox screen. Sensitivity was only 60% and positive predictive values were 30-47% for cannabis and drugs, respectively. CONCLUSION: These findings may negate the need for biochemical drug testing in this population, particularly as a "rule out" based on self-reporting. Future studies are needed to confirm these findings and should address risk of selection bias.
RESUMO
BACKGROUND: Trauma teams are often faced with patients on antithrombotic (AT) drugs, which is challenging when bleeding occurs. We sought to compare the effects of different AT medications on head injury severity and hypothesized that AT reversal would not improve mortality in severe traumatic brain injury (TBI) patients. METHODS: An Eastern Association for the Surgery of Trauma-sponsored prospective, multicentered, observational study of 15 trauma centers was performed. Patient demographics, injury burden, comorbidities, AT agents, and reversal attempts were collected. Outcomes of interest were head injury severity and in-hospital mortality. RESULTS: Analysis was performed on 2,793 patients. The majority of patients were on aspirin (acetylsalicylic acid [ASA], 46.1%). Patients on a platelet chemoreceptor blocker (P2Y12) had the highest mean Injury Severity Score (9.1 ± 8.1). Patients taking P2Y12 inhibitors ± ASA, and ASA-warfarin had the highest head Abbreviated Injury Scale (AIS) mean (1.2 ± 1.6). On risk-adjusted analysis, warfarin-ASA was associated with a higher head AIS (odds ratio [OR], 2.43; 95% confidence interval [CI], 1.34-4.42) after controlling for Injury Severity Score, Charlson Comorbidity Index, initial Glasgow Coma Scale score, and initial systolic blood pressure. Among patients with severe TBI (head AIS score, ≥3) on antiplatelet therapy, reversal with desmopressin (DDAVP) and/or platelet transfusion did not improve survival (82.9% reversal vs. 90.4% none, p = 0.30). In severe TBI patients taking Xa inhibitors who received prothrombin complex concentrate, survival was not improved (84.6% reversal vs. 84.6% none, p = 0.68). With risk adjustment as described previously, mortality was not improved with reversal attempts (antiplatelet agents: OR 0.83; 85% CI, 0.12-5.9 [p = 0.85]; Xa inhibitors: OR, 0.76; 95% CI, 0.12-4.64; p = 0.77). CONCLUSION: Reversal attempts appear to confer no mortality benefit in severe TBI patients on antiplatelet agents or Xa inhibitors. Combination therapy was associated with severity of head injury among patients taking preinjury AT therapy, with ASA-warfarin possessing the greatest risk. LEVEL OF EVIDENCE: Prognostic, level II.

BACKGROUND: Prehospital identification of the injured patient likely to require emergent care remains a challenge. End-tidal carbon dioxide (ETCO2) has been used in the prehospital setting to monitor respiratory physiology and confirmation of endotracheal tube placement. Low levels of ETCO2 have been demonstrated to correlate with injury severity and mortality in a number of in-hospital studies. We hypothesized that prehospital ETCO2 values would be predictive of mortality and need for massive transfusion (MT) in intubated patients. METHODS: This was a retrospective multicenter trial with 24 participating centers. Prehospital, emergency department, and hospital values were collected. Receiver operating characteristic curves were created and compared. Massive transfusion defined as >10 U of blood in 6 hours or death in 6 hours with at least 1 U of blood transfused. RESULTS: A total of 1,324 patients were enrolled. ETCO2 (area under the receiver operating characteristic curve [AUROC], 0.67; confidence interval [CI], 0.63-0.71) was better in predicting mortality than shock index (SI) (AUROC, 0.55; CI, 0.50-0.60) and systolic blood pressure (SBP) (AUROC, 0.58; CI, 0.53-0.62) (p < 0.0005). Prehospital lowest ETCO2 (AUROC, 0.69; CI, 0.64-0.75), SBP (AUROC, 0.75; CI, 0.70-0.81), and SI (AUROC, 0.74; CI, 0.68-0.79) were all predictive of MT. Analysis of patients with normotension demonstrated lowest prehospital ETCO2 (AUROC, 0.66; CI, 0.61-0.71), which was more predictive of mortality than SBP (AUROC, 0.52; CI, 0.47-0.58) or SI (AUROC, 0.56; CI, 0.50-0.62) (p < 0.001). Lowest prehospital ETCO2 (AUROC, 0.75; CI, 0.65-0.84), SBP (AUROC, 0.63; CI, 0.54-0.74), and SI (AUROC, 0.64; CI, 0.54-0.75) were predictive of MT in normotensive patients. ETCO2 cutoff for MT was 26 mm Hg. The positive predictive value was 16.1%, and negative predictive value was high at 98.1%. CONCLUSION: Prehospital ETCO2 is predictive of mortality and MT. ETCO2 outperformed traditional measures such as SBP and SI in the prediction of mortality. ETCO2 may outperform traditional measures in predicting need for transfusion in occult shock. LEVEL OF EVIDENCE: Diagnostic test, level III.

BACKGROUND: Police transport (PT) of penetrating trauma patients in urban locations has become routine in certain metropolitan areas; however, whether it results in improved outcomes over prehospital Advanced life support (ALS) transport has not been determined in a multicenter study. We hypothesized that PT would not result in improved outcomes. METHODS: This was a multicenter, prospective, observational study of adults (18+ years) with penetrating trauma to the torso and/or proximal extremity presenting at 25 urban trauma centers. Police transport and ALS patients were allocated via nearest neighbor, propensity matching. Transport mode also examined by Cox regression. RESULTS: Of 1,618 total patients, 294 (18.2%) had PT and 1,324 (81.8%) were by ALS. After matching, 588 (294/cohort) remained. The patients were primarily Black (n = 497, 84.5%), males (n = 525, 89.3%, injured by gunshot wound (n = 494, 84.0%) with 34.5% (n = 203) having Injury Severity Score of 16 or higher. Overall mortality by propensity matching was not different between cohorts (15.6% ALS vs. 15.0% PT, p = 0.82). In severely injured patients (Injury Severity Score ≥16), mortality did not differ between PT and ALS transport (38.8% vs. 36.0%, respectively; p = 0.68). Cox regression analysis controlled for relevant factors revealed no association with a mortality benefit in patients transported by ALS. CONCLUSION: Police transport of penetrating trauma patients in urban locations results in similar outcomes compared with ALS. Immediate transport to definitive trauma care should be emphasized in this patient population. LEVEL OF EVIDENCE: Prognostic and Epidemiologic; Level III.

BACKGROUND: Trauma is a leading cause of death worldwide and is thus a major public health concern. Previous studies have shown that limiting the amount of fluids given by following a strategy of permissive hypotension during the initial resuscitation period may improve trauma outcomes. This study examines the clinical outcomes from the first 90 patients enrolled in a prospective, randomized controlled trial of hypotensive resuscitation, with the primary aim of assessing the effects of a limited transfusion and intravenous (IV) fluid strategy on 30-day morbidity and mortality. METHODS: Patients in hemorrhagic shock who required emergent surgery were randomized to one of the two arms of the study for intraoperative resuscitation. Those in the experimental (low mean arterial pressure [LMAP]) arm were managed with a hypotensive resuscitation strategy in which the target mean arterial pressure (MAP) was 50 mm Hg. Those in the control (high MAP [HMAP]) arm were managed with standard fluid resuscitation to a target MAP of 65 mm Hg. Patients were followed up for 30 days. Intraoperative fluid requirements, mortality, postoperative complications, and other clinical data were prospectively gathered and analyzed. RESULTS: Patients in the LMAP group received a significantly less blood products and total i.v. fluids during intraoperative resuscitation than those in the HMAP group. They had significantly lower mortality in the early postoperative period and a nonsignificant trend for lower mortality at 30 days. Patients in the LMAP group were significantly less likely to develop immediate postoperative coagulopathy and less likely to die from postoperatively bleeding associated with coagulopathy. Among those who developed coagulopathy in both groups, patients in the LMAP group had significantly lower international normalized ratio than those in the HMAP group, indicating a less severe coagulopathy. CONCLUSIONS: Hypotensive resuscitation is a safe strategy for use in the trauma population and results in a significant reduction in blood product transfusions and overall IV fluid administration. Specifically, resuscitating patients with the intent of maintaining a target minimum MAP of 50 mm Hg, rather than 65 mm Hg, significantly decreases postoperative coagulopathy and lowers the risk of early postoperative death and coagulopathy. These preliminary results provide convincing evidence that support the continued investigation and use of hypotensive resuscitation in the trauma setting.
