Does lower extremity fracture fixation technique influence neurologic outcomes in patients with traumatic brain injury? The EAST Brain vs. Bone multicenter trial.

OBJECTIVE: This study aimed to determine whether lower extremity fracture fixation technique and timing (≤24 vs. >24 hours) impact neurologic outcomes in TBI patients. METHODS: A prospective observational study was conducted across 30 trauma centers. Inclusion criteria were age 18 years and older, head Abbreviated Injury Scale (AIS) score of >2, and a diaphyseal femur or tibia fracture requiring external fixation (Ex-Fix), intramedullary nailing (IMN), or open reduction and internal fixation (ORIF). The analysis was conducted using analysis of variamce, Kruskal-Wallis, and multivariable regression models. Neurologic outcomes were measured by discharge Ranchos Los Amigos Revised Scale (RLAS-R). RESULTS: Of the 520 patients enrolled, 358 underwent Ex-Fix, IMN, or ORIF as definitive management. Head AIS was similar among cohorts. The Ex-Fix group experienced more severe lower extremity injuries (AIS score, 4-5) compared with the IMN group (16% vs. 3%, p = 0.01) but not the ORIF group (16% vs. 6%, p = 0.1). Time to operative intervention varied between the cohorts with the longest time to intervention for the IMN group (median hours: Ex-Fix, 15 [8-24] vs. ORIF, 26 [12-85] vs. IMN, 31 [12-70]; p < 0.001). The discharge RLAS-R score distribution was similar across the groups. After adjusting for confounders, neither method nor timing of lower extremity fixation influenced the discharge RLAS-R. Instead, increasing age and head AIS score were associated with a lower discharge RLAS-R score (odds ratio [OR], 1.02; 95% confidence interval [CI], 1.002-1.03 and OR, 2.37; 95% CI, 1.75-3.22), and a higher Glasgow Coma Scale motor score on admission (OR, 0.84; 95% CI, 0.73-0.97) was associated with higher RLAS-R score at discharge. CONCLUSION: Neurologic outcomes in TBI are impacted by severity of the head injury and not the fracture fixation technique or timing. Therefore, the strategy of definitive fixation of lower extremity fractures should be dictated by patient physiology and the anatomy of the injured extremity and not by the concern for worsening neurologic outcomes in TBI patients.

Incidence, outcomes and costs of severe sepsis and septic shock in geriatric trauma patients: Analysis of 2,563,463 hospitalizations at 3,284 hospitals.

BACKGROUND: Severe sepsis/septic shock (sepsis) is a leading cause of death in hospitalized trauma patients. Geriatric trauma patients are an increasing proportion of trauma care but little recent, large-scale, research exists in this high-risk demographic. The objectives of this study are to identify incidence, outcomes and costs of sepsis in geriatric trauma patients. METHODS: Patients at short-term, nonfederal hospitals 65 years or older with ≥1 injury International Classification of Diseases, Tenth Revision, Clinical Modification code were selected from 2016 to 2019 Centers for Medicare & Medicaid Services Medicare Inpatient Standard Analytical Files. Sepsis was defined as International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis codes R6520 and R6521. A log-linear model was used to examine the association of Sepsis with mortality, adjusting for age, sex, race, Elixhauser score, and Injury Severity Score. Dominance analysis using logistic regression was used to determine the relative importance of individual variables in predicting Sepsis. Institutional review board exemption was granted for this study. RESULTS: There were 2,563,436 hospitalizations from 3,284 hospitals (62.8% female; 90.4% White; 72.7% falls; median ISS, 6.0). Incidence of Sepsis was 2.1%. Sepsis patients had significantly worse outcomes. Mortality risk was significantly higher in septic patients (adjusted risk ratio, 3.98, 95% confidence interval, 3.92-4.04). Elixhauser score contributed the most to the prediction of Sepsis, followed by ISS (McFadden's R2 = 9.7% and 5.8%, respectively). CONCLUSION: Severe sepsis/septic shock occurs infrequently among geriatric trauma patients but is associated with increased mortality and resource utilization. Pre-existing comorbidities influence Sepsis occurrence more than Injury Severity Score or age in this group, identifying a population at high risk. Clinical management of geriatric trauma patients should focus on rapid identification and prompt aggressive action in high-risk patients to minimize the occurrence of sepsis and maximize survival.

Survey of Diagnostic and Management Practices in Small Bowel Obstruction: Individual and Generational Variation Despite Practice Guidelines.

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.

Low Prevalence but High Impact of COVID-19 Positive Status in Adult Trauma Patients: A Multi-institutional Analysis of 28 904 Patients.

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.

Findings on Repeat Posttraumatic Brain Computed Tomography Scans in Older Patients With Minimal Head Trauma and the Impact of Existing Antithrombotic Use.

STUDY OBJECTIVE: Evaluate the utility of routine rescanning of older, mild head trauma patients with an initial negative brain computed tomography (CT), who is on a preinjury antithrombotic (AT) agent by assessing the rate of delayed intracranial hemorrhage (dICH), need for surgery, and attributable mortality. METHODS: Participating centers were trained and provided data collection instruments per institutional review board-approved protocols. Data were obtained from manual chart review and electronic medical record download. Adults ≥55 years seen at Level I/II Trauma Centers, between 2017 and 2019 with suspected head trauma, Glasgow Coma Scale 14 to 15, negative initial brain CT, and no other Abbreviated Injury Scale injuries >2 were identified, grouped by preinjury AT therapy (AT- or AT+) and compared on dICH rate, need for operative neurosurgical intervention, and attributable mortality using univariate analysis (α=.05). RESULTS: A total of 2,950 patients from 24 centers were enrolled; 280 (9.5%) had a repeat brain CT. In those rescanned, the dICH rate was 15/126 (11.9%) for AT- and 6/154 (3.9%) in AT+. Assuming nonrescanned patients did not suffer clinically meaningful dICH, the dICH rate would be 15/2001 (0.7%) for AT- and 6/949 (0.6%) for AT+. No surgical operations were done for dICH. All-cause mortality was 9/2950 (0.3%) and attributable mortality was 1/2950 (0.03%). The attributable death was an AT+, dICH patient whose family declined intervention. CONCLUSION: In older patients with an initial Glasgow Coma Scale of 14 to 15 and a negative initial brain CT scan, the dICH rate is low (<1%) and of minimal clinical consequence, regardless of AT use. In addition, no patient had operative neurosurgical intervention. Therefore, routine rescanning is not supported based on the results of this study.

Hyperglycemia in nondiabetic adult trauma patients is associated with worse outcomes than diabetic patients: An analysis of 95,764 patients.

BACKGROUND: The adverse impact of acute hyperglycemia is well documented but its specific effects on nondiabetic trauma patients are unclear. The purpose of this study was to analyze the differential impact of hyperglycemia on outcomes between diabetic and nondiabetic trauma inpatients. METHODS: Adults admitted 2018 to 2019 to 46 Level I/II trauma centers with two or more blood glucose tests were analyzed. Diabetes status was determined from International Classification of Diseases-10th Rev.-Clinical Modification, trauma registry, and/or hemoglobin A1c greater than 6.5. Patients with and without one or more hyperglycemic result >180 mg/dL were compared. Logistic regression examined the effects of hyperglycemia and diabetes on outcomes, adjusting for age, sex, Injury Severity Score, and body mass index. RESULTS: There were 95,764 patients: 54% male; mean age, 61 years; mean Injury Severity Score, 10; diabetic, 21%. Patients with hyperglycemia had higher mortality and worse outcomes compared with those without hyperglycemia. Nondiabetic hyperglycemic patients had the highest odds of mortality (diabetic: adjusted odds ratio, 3.11; 95% confidence interval, 2.8-3.5; nondiabetics: adjusted odds ratio, 7.5; 95% confidence interval, 6.8-8.4). Hyperglycemic nondiabetics experienced worse outcomes on every measure when compared with nonhyperglycemic nondiabetics, with higher rates of sepsis (1.1 vs. 0.1%, p < 0.001), more SSIs (1.0 vs. 0.1%, p < 0.001), longer mean hospital length of stay (11.4 vs. 5.0, p < 0.001), longer mean intensive care unit length of stay (8.5 vs. 4.0, p < 0.001), higher rates of intensive care unit use (68.6% vs. 35.1), and more ventilator use (42.4% vs. 7.3%). CONCLUSION: Hyperglycemia is associated with increased odds of mortality in both diabetic and nondiabetic patients. Hyperglycemia during hospitalization in nondiabetics was associated with the worst outcomes and represents a potential opportunity for intervention in this high-risk group. LEVEL OF EVIDENCE: Therapeutic/care management; Level III.

The public health burden of geriatric trauma: Analysis of 2,688,008 hospitalizations from Centers for Medicare and Medicaid Services inpatient claims.

BACKGROUND: Geriatric trauma care (GTC) represents an increasing proportion of injury care, but associated public health research on outcomes and expenditures is limited. The purpose of this study was to describe GTC characteristics, location, diagnoses, and expenditures. METHODS: Patients at short-term nonfederal hospitals, 65 years or older, with ≥1 injury International Classification of Diseases, Tenth Revision, were selected from 2016 to 2019 Centers for Medicare and Medicaid Services Inpatient Standard Analytical Files. Trauma center levels were linked to Inpatient Standard Analytical Files data via American Hospital Association Hospital ID and fuzzy string matching. Demographics, care location, diagnoses, and expenditures were compared across groups. RESULTS: A total of 2,688,008 hospitalizations (62% female; 90% White; 71% falls; mean Injury Severity Score, 6.5) from 3,286 hospitals were included, comprising 8.5% of all Medicare inpatient hospitalizations. Level I centers encompassed 7.2% of the institutions (n = 236) but 21.2% of hospitalizations, while nontrauma centers represented 58.5% of institutions (n = 1,923) and 37.7% of hospitalizations. Compared with nontrauma centers, patients at Level I centers had higher Elixhauser scores (9.0 vs. 8.8) and Injury Severity Score (7.4 vs. 6.0; p < 0.0001). The most frequent primary diagnosis at all centers was hip/femur fracture (28.3%), followed by traumatic brain injury (10.1%). Expenditures totaled $32.9 billion for trauma-related hospitalizations, or 9.1% of total Medicare hospitalization expenditures and approximately 1.1% of the annual Medicare budget. The overall mortality rate was 3.5%. CONCLUSION: Geriatric trauma care accounts for 8.5% of all inpatient GTC and a similar percentage of expenditures, the most common injury being hip/femur fractures. The largest proportion of GTC occurs at nontrauma centers, emphasizing their vital role in trauma care. Public health prevention programs and GTC guidelines should be implemented by all hospitals, not just trauma centers. Further research is required to determine the optimal role of trauma systems in GTC, establish data-driven triage guidelines, and define the impact of trauma centers and nontrauma centers on GTC mortality.

Into the wild and on to the table: A Western Trauma Association multicenter analysis and comparison of wilderness falls in rock climbers and nonclimbers.

BACKGROUND: Wilderness activities expose outdoor enthusiasts to austere environments with injury potential, including falls from height. The majority of published data on falls while climbing or hiking are from emergency departments. We sought to more accurately describe the injury pattern of wilderness falls that lead to serious injury requiring trauma center evaluation and to further distinguish climbing as a unique pattern of injury. METHODS: Data were collected from 17 centers in 11 states on all wilderness falls (fall from cliff: International Classification of Diseases, Ninth Revision, e884.1; International Classification of Diseases, 10th Revision, w15.xx) from 2006 to 2018 as a Western Trauma Association multicenter investigation. Demographics, injury characteristics, and care delivery were analyzed. Comparative analyses were performed for climbing versus nonclimbing mechanisms. RESULTS: Over the 13-year study period, 1,176 wilderness fall victims were analyzed (301 climbers, 875 nonclimbers). Fall victims were male (76%), young (33 years), and moderately injured (Injury Severity Score, 12.8). Average fall height was 48 ft, and average rescue/transport time was 4 hours. Nineteen percent were intoxicated. The most common injury regions were soft tissue (57%), lower extremity (47%), head (40%), and spine (36%). Nonclimbers had a higher incidence of severe head and facial injuries despite having equivalent overall Injury Severity Score. On multivariate analysis, climbing remained independently associated with increased need for surgery but lower odds of composite intensive care unit admission/death. Contrary to studies of urban falls, height of fall in wilderness falls was not independently associated with mortality or Injury Severity Score. CONCLUSION: Wilderness falls represent a unique population with distinct patterns of predominantly soft tissue, head, and lower extremity injury. Climbers are younger, usually male, more often discharged home, and require more surgery but less critical care. LEVEL OF EVIDENCE: Epidemiological, Level IV.

Efficacy of a Bioresorbable Matrix in Healing Complex Chronic Wounds: An Open-Label Prospective Pilot Study

OBJECTIVE: The goal of this prospective clinical study was to assess the effectiveness of a novel bioresorbable polymeric matrix impregnated with ionic and metallic silver as a primary wound contact dressing in healing stagnant or deteriorating chronic wounds. MATERIALS AND METHODS: Thirty-two patients with a total of 35 chronic wounds undergoing treatment at the Wound Healing and Hyperbaric Center at Mission Hospital were recruited under a protocol approved by the institutional review board. The wounds included venous stasis ulcers, diabetic foot ulcers, postoperative surgical wounds, burn wounds, and chronic, nonpressure lower extremity ulcers. At baseline, all wounds were nonhealing (ie, stagnant or deteriorating) for a median of 39 weeks (range, 3-137 weeks) and suspected of persistent microbial colonization that had not responded to traditional antimicrobial products and/or antibiotics. The aforementioned matrix was applied to wounds once every 3 days and covered with a secondary dressing. Previously prescribed protocols of care, such as debridement or compression wraps, were continued, but prior antimicrobial dressings or antibiotics were replaced with the matrix. Wound assessments at 3 weeks and 12 weeks post intervention are reported. RESULTS: Three patients were excluded due to patients lost to follow-up after initial application. At 3 weeks, 72% of wounds (22/32) had significantly improved healing with an average wound area reduction of 66%. By 12 weeks, 91% of wounds (29/32) either healed completely (ie, fully reepithelialized) or improved significantly with an average wound area reduction of 73%. The matrix was well tolerated; no patient reported discomfort with the application of the matrix. CONCLUSIONS: The micrometer-thick bioresorbable matrix presents a new form factor to wound management, conforming intimately to the underlying wound bed to exert localized and sustained antimicrobial action of noncytotoxic levels of silver. The application of the matrix on the wound surface in protocols of care was safe and well tolerated, and it facilitated improvements in healing of a majority of the stagnant or deteriorating complex chronic wounds.

Prevention of firearm injuries with gun safety devices and safe storage: An Eastern Association for the Surgery of Trauma Systematic Review.

BACKGROUND: Over 50,000 homicides and suicides occur each year. An estimated half of all US households are believed to have a firearm present, making them one of the most ubiquitous consumer products. Our goal was to determine if the manner of storage of a firearm in a home could potentially make a difference in the outcomes of intentional and unintentional injuries involving a firearm; specifically addressing the use of gun safes and devices that block/disable firearm function (trigger locks, cable locks, etc.). METHODS: A comprehensive review of the literature was performed. We used Grading of Recommendations Assessment, Development, and Evaluation methodology to assess the breadth and quality of the data specific to our Population, Intervention, Comparator, Outcomes (PICO) questions. RESULTS: A total of 176 studies were initially identified, then, 120 more added after a subsequent literature review, with 97 removed as duplicates. One hundred ninety-one case reports, case series, and reviews were removed because they did not focus on prevention or did not address our comparators of interest. This left a total of two studies which merited inclusion for PICO 1, should gun locks be used to prevent firearm injuries and six studies which merited inclusion for PICO 2, should safe storage for guns be used to prevent firearm injuries. CONCLUSION: PICO 1: We conditionally recommend that gun locks be used to prevent unintentional firearm injury. PICO 2: Because of the large effect size and the reasonable quality of available evidence with safe storage of firearms, we recommend safe storage prevent firearm-related injuries. LEVEL OF EVIDENCE: Systematic review, level III.

Prevention of firearm-related injuries with restrictive licensing and concealed carry laws: An Eastern Association for the Surgery of Trauma systematic review.

BACKGROUND: In the past decade, more than 300,000 people in the United States have died from firearm injuries. Our goal was to assess the effectiveness of two particular prevention strategies, restrictive licensing of firearms and concealed carry laws, on firearm-related injuries in the US Restrictive Licensing was defined to include denials of ownership for various offenses, such as performing background checks for domestic violence and felony convictions. Concealed carry laws allow licensed individuals to carry concealed weapons. METHODS: A comprehensive review of the literature was performed. We used Grading of Recommendations Assessment, Development, and Evaluation methodology to assess the breadth and quality of the data specific to our Population, Intervention, Comparator, Outcomes (PICO) questions. RESULTS: A total of 4673 studies were initially identified, then seven more added after two subsequent, additional literature reviews. Of these, 3,623 remained after removing duplicates; 225 case reports, case series, and reviews were excluded, and 3,379 studies were removed because they did not focus on prevention or did not address our comparators of interest. This left a total of 14 studies which merited inclusion for PICO 1 and 13 studies which merited inclusion for PICO 2. CONCLUSION: PICO 1: We recommend the use of restrictive licensing to reduce firearm-related injuries.PICO 2: We recommend against the use of concealed carry laws to reduce firearm-related injuries.This committee found an association between more restrictive licensing and lower firearm injury rates. All 14 studies were population-based, longitudinal, used modeling to control for covariates, and 11 of the 14 were multi-state. Twelve of the studies reported reductions in firearm injuries, from 7% to 40%. We found no consistent effect of concealed carry laws. Of note, the varied quality of the available data demonstrates a significant information gap, and this committee recommends that we as a society foster a nurturing and encouraging environment that can strengthen future evidence based guidelines. LEVEL OF EVIDENCE: Systematic review, level III.

Outcomes of expanded use of clinical pharmacist practitioners in addition to team-based care in a community health system intensive care unit.

PURPOSE: Clinical and cost benefits achieved through expanded use of state-licensed clinical pharmacist practitioners (CPPs) with prescribing authority on a critical care team are reported. METHODS: A retrospective pre-post analysis was conducted to evaluate patient care outcomes and cost savings during one-year periods before and after the number of CPPs on a North Carolina community health system's neurotrauma intensive care unit (NTICU) team was increased from one to three. Outcomes assessed included the number and types of medication management encounters, estimated cost savings, and the rate of preventable adverse drug events (ADEs) with expanded use of CPPs. RESULTS: During the two-year study period, CPPs conducted 13,386 documented medication encounters involving 2,198 patients; associated cost savings totaled an estimated $2,118,426. During the 12 months after CPP involvement on the NTICU team was increased, there was a 182% increase in encounters for therapeutic optimization (p = 0.01), with an associated 29% increase in cost savings and an improved return on investment. The CPP service expansion was also associated with a reduction in preventable ADEs, including a 75% reduction in prescribing-related ADEs (risk ratio [RR], 0.25; 95% confidence interval [CI], 0.05-1.2; p = 0.09) and a 37% reduction in higher-severity ADEs (RR, 0.63; 95% CI, 0.25-1.57; p = 0.36). CONCLUSION: With expanded CPP involvement on the NTICU team, there was a substantial increase in therapeutic optimization interventions and a clinically notable reduction in preventable ADEs, as well as an estimated 30% increase in associated cost savings.
