Outcomes of patients with traumatic brain injury after stress ulcer prophylaxis: a retrospective multicenter study.

Background: Stress ulcers in patients with traumatic brain injury (TBI) and spinal cord injury (SCI) present significant morbidity and mortality risks. Despite the low reported stress ulcer rates, stress ulcer prophylaxis (SUP) is widely administered in neurocritical care. It was hypothesized that universal SUP administration may not be associated with reduced rates of complications across all neurocritical care patients. Methods: This retrospective study encompassed neurocritical care patients aged ≥18 with moderate or severe TBI or SCI, admitted to the intensive care unit (ICU) between October 2020 and September 2021, across six level I trauma centers. Exclusions included patients with an ICU stay <2 days, prior SUP medication use, and pre-existing SUP diagnoses. The primary exposure was SUP, with the primary outcome being clinically significant gastrointestinal bleeds (CSGIBs). Secondary outcomes included pneumonia and in-hospital mortality. Patients were stratified by admission Glasgow Coma Scale (GCS) groups. Results: Among 407 patients, 83% received SUP, primarily H2 receptor antagonists (88%) and proton pump inhibitors (12%). Patients on SUP were significantly younger, had lower admission GCS scores, higher Injury Severity Scores, longer ICU stays, and higher rates of mechanical ventilation than non-SUP patients. Overall, CSGIBs were rare (1%) and not significantly different between the SUP and non-SUP groups (p=0.06). However, CSGIBs exclusively occurred in patients with GCS scores of 3-8, and SUP was associated with a significantly lower rate of CSGIBs in this subgroup (p=0.03). SUP was also linked to significantly higher pneumonia rates in both GCS 3-8 and GCS 9-12 patients. Conclusions: This study highlights the low incidence of CSGIBs in neurocritical trauma patients and suggests potential benefits of SUP, particularly for those with severe neurological impairment. Nevertheless, the increased risk of pneumonia associated with SUP in these patients warrants caution. Further research is crucial to refine SUP guidelines for neurocritical care patients and inform optimal strategies. Level of evidence: Level III, retrospective.

Border-fence falls versus domestic falls at a South Texas trauma center.

Objectives: Falling from height may lead to significant injuries and time hospitalized; however, there are few studies comparing the specific mechanism of fall. The purpose of this study was to compare injuries from falls after attempting to cross the USA-Mexico border fence (intentional) with injuries from domestic falls (unintentional) of comparable height. Methods: This retrospective cohort study included all patients admitted after a fall from a height of 15-30 ft to a level II trauma center between April 2014 and November 2019. Patient characteristics were compared by falls from the border fence with those who fell domestically. Fisher's exact test, χ2 test and Wilcoxon Mann-Whitney U test were used as appropriate. A significance level of α<0.05 was used. Results: Of the 124 patients included, 64 (52%) were falls from the border fence while 60 (48%) were domestic falls. Patients sustaining injuries from border falls were on average younger than patients who had domestic falls (32.6 (10) vs 40.0 (16), p=0.002), more likely males (58% vs 41%, p<0.001), fell from a significantly higher distance (20 (20-25) vs 16.5 (15-25), p<0.001), and had a significantly lower median injury severity score (ISS) (5 (4-10) vs 9 (5-16.5), p=0.001). Additionally, compared with domestic falls, border falls had fewer injuries to the head (3% vs 25%, p=0.004) and chest (5% vs 27%, p=0.007), yet more extremity injuries (73% vs 42%, p=0.003), and less had an intensive care unit (ICU) stay (30% vs 63%, p=0.002). No significant differences in mortality were found. Conclusion: Patients sustaining injuries from border crossing falls were slightly younger, and although fell from higher, had a lower ISS, more extremity injuries, and fewer were admitted to the ICU compared with patients sustaining falls domestically. There was no difference in mortality between groups. Level of evidence: Level III, retrospective study.

Predictors of transfer from a remote trauma facility to an urban level I trauma center for blunt splenic injuries: a retrospective observational multicenter study.

BACKGROUND: The decision-making for admission versus emergent transfer of patients with blunt splenic injuries presenting to remote trauma centers with limited resources remains a challenge. Although splenectomy is standard for hemodynamically unstable patients, the specific criterion for non-operative management continues to be debated. Often, lower-level trauma centers do not have interventional radiology capabilities for splenic artery embolization, leading to transfer to a higher level of a care. Thus, the aim of this study was to identify specific characteristics of patients with blunt splenic injuries used for admittance or transfer at a remote trauma center. METHODS: A retrospective observational study was performed to examine the management of splenic injuries at a mountainous and remote Level III trauma center. Trauma patients ≥ 18 years who had a blunt splenic injury and initially received care at a Level III trauma center prior to admittance or transfer were included. Data were collected over 4.5 years (January 1, 2016 - June 1, 2020). Patients who were transferred out in > 24 h were excluded. Patient demographics, injury severity, spleen radiology findings, and clinical characteristics were compared by decision to admit or transfer to a higher level of care ≤ 24 h of injury. Results were analyzed using chi-square, Fisher's exact, or Wilcoxon tests. Multivariable logistic models were used to identify predictors of transfer. RESULTS: Of the 73 patients included with a blunt splenic injury, 48% were admitted and 52% were transferred to a Level I facility. Most patients were male (n = 58), were a median age of 26 (21-42) years old, most (n = 62) had no comorbidities, and 47 had been injured from a ski/snowboarding accident. Compared to admitted patients, transferred patients were significantly more likely to be female (13/38 vs. 3/36, p = 0.007), to have an abbreviated injury scale score ≥ 3 of the chest (31/38 vs. 7/35, p = 0.002), have a higher injury severity score (16 (16-22) vs. 13 (9-16), p = 0.008), and a splenic injury grade ≥ 3 (32/38 vs. 12/35, p < 0.001). After adjustment, splenic injury grade ≥ 3 was the only predictor of transfer (OR: 12.1, 95% CI: 3.9-37.3, p < 0.001). Of the 32 transfers with grades 3-5, 16 were observed, and 16 had an intervention. Compared to patients who were observed after transfer, significantly more who received an intervention had a blush on CT (1/16 vs. 7/16, p = 0.02) and a higher median spleen grade of 4 (3-5) vs. 3 (3-3.5), p = 0.01). CONCLUSIONS: Our data suggest that most patients transferred from a remote facility had a splenic injury grade ≥ 3, with concomitant injuries but were hemodynamically stable and were successfully managed non-operatively. Stratifying by spleen grade may assist remote trauma centers with refining transfer criteria for solid organ injuries.

An Educational Outreach Program: A Trauma System's 5-Year Experience.

BACKGROUND: The American College of Surgeons Committee on Trauma requires Level I and II trauma centers to provide educational outreach to lower-level facilities. Although outreach is a required part of any trauma system, very little is published on the resources required for a successful program. OBJECTIVE: The purpose of this article is to provide a comprehensive roadmap of the required components to achieve a successful trauma outreach program. METHODS: This project describes the development and implementation of an educational outreach program from January 2016 to December 2020 that has grown from 27 facilities within one western state to 49 facilities across 14 different states. Program components measured include the number and attendance of trauma courses offered, including the Trauma Nursing Core Course (TNCC), Advanced Trauma Life Support (ATLS), Rural Trauma Team Development Course (RTTDC), the number of trauma meetings and webinars provided, total trauma center designation and reviews, total states reached, and total trauma center collaborations. RESULTS: From 2016 to 2020, the program more than doubled the number of TNCC and ATLS courses, maintained the number of RTTDC offered, and observed attendance rate increases of 33% and 11% for TNCC and ATLS courses, respectively. Outreach leadership attended 44 trauma meetings and educational webinars using virtual platform technology, nearly doubling the trauma center outreach with expansion across 14 states resulting in important changes in practice. CONCLUSION: With administrative support, effective leadership, and technology, outreach programs can serve as important resources for statewide trauma systems.

Examining trends in gun violence injuries before and during the COVID-19 pandemic across six trauma centers.

OBJECTIVES: The onset of the national stay-at-home orders accompanied by a surge in firearm sales has elevated the concerns of clinicians and public health authorities. The purpose of this study was to examine the impact of the stay-at-home orders among gunshot wound (GSW) trauma admissions. METHODS: This was a retrospective cohort study at six level I trauma centers across four states. Patients admitted after the onset of COVID-19 restrictions (March 16, 2020-June 30, 2020) were compared with those admitted during the same period in 2019. We compared (1) rate of patients with GSW and (2) characteristics of patients with GSW, by period using Χ2 tests or Fisher's exact tests, as appropriate. RESULTS: There were 6996 trauma admissions across the study period; 3707 (53%) in 2019 and 3289 (47%) in 2020. From 2019 to 2020, there was a significant increase in GSW admissions (4% vs. 6%, p=0.001); 4 weeks specifically had significant increases (March 16-March 23: 4%, April 1-April 8: 5%, April 9-April 16: 6%, and May 11-May 18: 5%). Of the 334 GSWs, there were significant increases in patients with mental illness (5% vs. 11%, p=0.03), alcohol use disorder (2% vs. 10%, p=0.003), substance use disorder (11% vs. 25%, p=0.001), and a significant decrease in mortality (14% vs. 7%, p=0.03) in 2020. No other significant differences between time periods were identified. CONCLUSION: Our data suggest that trauma centers admitted significantly more patients with GSW following the national guidelines, including an increase in those with mental illness and substance use-related disorders. This could be attributable to the stay-at-home orders. LEVEL OF EVIDENCE: Level III, retrospective study.

The ACS-TQIP palliative care guidelines at two level I trauma centres: a prospective study of patient and caregiver satisfaction.

OBJECTIVES: To measure trauma patient and caregiver satisfaction before and after implementation of standardised palliative care (PC) guidelines. METHODS: Prospective pre-post study at two level-I trauma centres. PC satisfaction surveys were administered prior to discharge for consented trauma patients (Family Satisfaction with Advanced Cancer Scale, Patient (FAMCARE-P13) survey)≥55 years, and their caregivers (FAMCARE survey), from 1 November 2016 to 30 November 2018. Standardised PC guidelines were implemented January 2018 and included consultations, prognostication assessments, identification of proxies, review of advanced directives and do not resuscitate orders within 24 hours of admission, while advanced goals of care, formal family meetings and spiritual care support were recommended within 72 hours of admission. Generalised linear models were used to determine whether differences in patient or caregiver satisfaction existed pre versus post implementation. RESULTS: There were 572 patients (299 pre; 273 post) and 595 caregivers (334 pre; 261 post) included. Overall patient satisfaction significantly increased post implementation (82.0 vs 86.0, p=0.001). After adjustment, the implementation of the guidelines was an independent predictor of higher overall patient satisfaction (least squares mean (LSM= (83.8% (95%CI 81.2%-86.5%) vs 80.3% (77.7%-82.9%), p=0.003)). Compared with preimplementation, patient satisfaction was significantly higher post implementation in the following domains: information giving (80.9 vs 85.5, p=0.001), followed by physical care (82.2 vs 86.0, p=0.002), availability of care (83.4 vs 86.8, p=0.007) and psychosocial care (84.7 vs 87.6, p=0.04). No significant differences in caregiver satisfaction were found before or after adjustment (LSMpre: 83.1% (95%CI 80.9%-85.3%) vs. post: 82.4% (80.3%-84.5%), p=0.56)) CONCLUSIONS: Our data suggest that the implementation of PC guidelines significantly improved patient satisfaction following traumatic injury, while maintaining robust caregiver satisfaction.

Patterns of alcohol and drug utilization in trauma patients during the COVID-19 pandemic at six trauma centers.

BACKGROUND: Since the national stay-at-home order for COVID-19 was implemented, clinicians and public health authorities worldwide have expressed growing concern about the potential repercussions of drug and alcohol use due to social restrictions. We explored the impact of the national stay-at-home orders on alcohol or drug use and screenings among trauma admissions. METHODS: This was a retrospective cohort study at six Level I trauma centers across four states. Patients admitted during the period after the onset of the COVID-19 restrictions (defined as March 16, 2020-May 31, 2020) were compared with those admitted during the same time period in 2019. We compared 1) rate of urine drug screens and blood alcohol screens; 2) rate of positivity for drugs or alcohol (blood alcohol concentration ≥ 10 mg/dL); 3) characteristics of patients who were positive for drug or alcohol, by period using chi-squared tests or Fisher's exact tests, as appropriate. Two-tailed tests with an alpha of p < 0.05 was used on all tests. RESULTS: There were 4762 trauma admissions across the study period; 2602 (55%) in 2019 and 2160 (45%) in 2020. From 2019 to 2020, there were statistically significant increases in alcohol screens (34% vs. 37%, p = 0.03) and drug screens (21% vs. 26%, p < 0.001). Overall, the rate of alcohol positive patients significantly increased from 2019 to 2020 (32% vs. 39%, p = 0.007), while the rate of drug positive patients was unchanged (57% vs. 52%, p = 0.13). Of the 1025 (22%) patients who were positive for alcohol or drugs, there were significant increases in a history of alcoholism (41% vs. 26%, p < 0.001), and substance abuse (11% vs. 23%, p < 0.001) in the 2020 period. No other statistically significant differences were identified among alcohol or drug positive patients during COVID-19 compared to the same period in 2019. CONCLUSIONS: Our first wave of COVID-19 data suggests that trauma centers were admitting significantly more patients who were alcohol positive, as well those with substance use disorders, potentially due to the impact of social restrictions and guidelines. Further longitudinal research is warranted to assess the alcohol and drug positive rates of trauma patients over the COVID-19 pandemic.

Is preexisting mental illness associated with lower patient satisfaction for older trauma patients? A cross-sectional descriptive study.

BACKGROUND: The purpose of this study was to examine if satisfaction with care differs among older trauma patients with and without preexisting mental illness (PMI+/PMI-). METHODS: Data from two level I trauma centers were examined from 11/2016 through 12/2017. Trauma patients ≥55 years were included and satisfaction of those who had a diagnosis of mental illness prior to the trauma admission (PMI+) to those without a diagnosis (PMI-) (n = 299; 62 PMI+ and 237 PMI-) were compared. Enrolled patients completed the Family Satisfaction with Advanced Care Cancer Scale Patient Survey (FAMCARE-P13) prior to discharge. Associations between mental illness status and patient baseline characteristics, overall mean satisfaction, and mean satisfaction by question were compared. Generalized linear models adjusted for differences in patient satisfaction by mental illness status. Analyses were stratified by hospital to account for the interaction between hospital and mental illness status. RESULTS: Compared to PMI- patients, PMI+ patients were more likely to be younger, female, have multiple comorbidities, and to report lower overall satisfaction with care. Among PMI+ patients, the most common diagnoses were depression and anxiety. After adjustment, PMI+ was associated with lower patient satisfaction at hospital 1; after examining individual questions lower satisfaction was associated with information provided on procedures and questions surrounding "Physical care." Conversely, PMI+ did not affect satisfaction at hospital 2 after adjustment. CONCLUSIONS: At hospital 1, room for improvement was identified in providing information about prognosis and procedures, symptom management, and continuity of care. Reexamining practices for older PMI+ trauma patients is warranted.

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.

Comparing satisfaction of trauma patients 55 years or older to their caregivers during palliative care: Who faces the burden?

BACKGROUND: Many studies report on the patient-caregiver relationship during palliative care (PC); however, this relationship has yet to be examined following traumatic injury. METHODS: This prospective cohort study included trauma patients (≥55 years) and their primary caregivers admitted at two level I trauma centers for 2 years (November 2016 to November 2018), who received PC and who completed satisfaction surveys before discharge; surveys were analyzed by four domains: information giving, availability of care, physical care, and psychosocial care, and by PC assessments: consultations, prognostications, formal family meetings (FFMs), and advanced goals of care discussions. The primary outcome was the percentage of patients and caregivers who were satisfied (defined as ≥80%) and was analyzed using McNemar's test. Adjusted mixed models identified PC assessments that were associated with satisfaction scores ≥80% for patients and caregivers. RESULTS: Of the 441-patient and 441-caregiver pairs, caregivers were significantly less satisfied than patients during prognostications (information giving, physical care), FFMs (information giving, physical care), and consultations (physical care), while caregivers were significantly more satisfied than patients during advanced goals of care discussions (availability of care, psychosocial care). After adjustment, significant predictors of caregiver satisfaction (≥80%) included longer patient hospital length of stay (>4 days), caring for a male patient (physical care, availability of care), higher caregiver age (≥55 years; availability of care), and higher patient age (≥65 years; psychosocial care). Conversely, all PC assessments decreased odds of satisfaction for caregivers in every domain except physical care. Significant predictors of higher patient satisfaction included FFMs (for every domain) and PC consultations (psychosocial care), and decreased odds included advanced goals of care discussions and prognostication assessments (information giving, psychosocial care). CONCLUSIONS: Palliative care increased satisfaction of patients, especially family meetings and consultations, while assessments were predictive of lower caregiver satisfaction, suggesting that caregivers may be experiencing some of the patient burden. LEVEL OF EVIDENCE: Therapeutic/Care Management, level IV.

How long are mechanically ventilated patients fasted prior to surgery? An exploratory study examining preoperative fasting practices across trauma centres.

For mechanically ventilated patients undergoing surgery, interrupting enteral feeding to prevent pulmonary aspiration is common; however, there are no published preoperative fasting guidelines for these patients, resulting in fasting practices that often vary greatly between hospitals. This retrospective study described fasting practices and surgical outcomes of mechanically ventilated patients across five trauma centres. The primary exposure was hours nil per os before surgery and was stratified into short (<6h) and moderate (≥6h) fasting duration. Shared frailty models assessed the relationship between time to perioperative complication and nil per os category. Three of the five hospitals had preoperative fasting guidelines, and those most compliant required patients to be fed up until surgery. Most patients were fasted ≥6h prior to surgery and no increased risk of complication was found for patients who were fasted <6h. Future studies are needed to establish appropriate preoperative fasting thresholds for mechanically ventilated patients.

Examining satisfaction of older adult patients and their caregivers following traumatic injury: a cross-sectional study of three level I trauma centres.

OBJECTIVE: To explore satisfaction of care received by older adult patients and their primary caregivers following traumatic injury. DESIGN: Prospective, cross-sectional study using the FAMCARE (Family Satisfaction with Advanced Cancer Care Scale) satisfaction surveys prior to discharge. SETTING: Three level I trauma centres in Colorado from November 2016 to December 2017. PARTICIPANTS: Trauma patients ≥55 years old and their primary caregivers. OUTCOME MEASURES: Overall mean (SD) satisfaction, satisfaction <80% vs ≥80%, and mean satisfaction by survey conceptual structures. RESULTS: Of the 319 patients and 336 caregivers included, the overall mean (SD) patient satisfaction was 81.7% (15.0%) and for caregivers was 83.6% (13.4%). The area with the highest mean for patient and caregiver satisfaction was psychosocial care (85.4% and 86.9%, respectively). Information giving was the lowest for patients (80.4%) and caregivers (80.9%). When individual items were examined, patients were significantly more satisfied with 'availability of nurses to answer questions' (84.5 (15.3) vs 87.4 (14.8), p=0.02) and significantly less satisfied with 'speed with which symptoms were treated' (80.6 (17.9) vs 84.0 (17.0), p=0.03) compared with caregivers. Patients with a history of smoking (least squares mean difference: -0.096 (-0.18 to -0.07), p<0.001) and hospital discharge destination to an outside facility of care (adjusted OR: 1.6 (1.0 to 2.4), p=0.048) were identified as independent predictors of lower overall satisfaction in generalised linear and logistic models, respectively. CONCLUSIONS: Our data suggest that patients' medical history was driving both patient and caregiver satisfaction. Patient characteristics and expectations need to be considered when tailoring healthcare interventions.

Severe fungal infections following blunt traumatic injuries: A 5-year multicenter descriptive study.

INTRODUCTION: The aggressive and timely treatment of post-traumatic fungal infections is the most efficacious way to reduce morbidity and mortality. Compared to the military trauma population, studies reporting on fungal infections in civilian trauma are not well described. The purpose of this study was to describe characteristics of civilian trauma patients who developed fungal infections and to identify common risk factors and report any delays between injury and treatment. METHODS: This was a five-year (1/1/2013-3/1/2018) retrospective, descriptive study across six level 1 trauma centers. All consecutively admitted trauma patients (≥18 years) with laboratory-confirmed fungal wound infections were included. Patients with solely candida wound isolates were excluded. Patient demographics, clinical wound and infection characteristics, organisms cultured, treatment modalities, length of stay, in-hospital mortality, and any diagnostic or treatment delays were described. RESULTS: Of the 54,521 trauma patients screened for fungal infection, 12 were identified. All patients suffered major injuries after blunt trauma (abbreviated injury score 3-5) and sustained wound contamination, and in nine patients, the cause of injury was motor vehicle. Six had open wounds/fractures on admission. The geographical region with the highest rate of fungal infection was Texas (n = 7), followed by Kansas (N = 3), then Missouri (N = 2). First symptoms of infection (leukocytosis or fever (n = 10)) presented a median of 6.3 (4.1-9.8) days after injury. Wound management entailed a combination of debridements (n = 8), negative pressure wound therapy (n = 9), amputation (n = 6), and antifungal treatment (n = 10). All fungal isolates identified from the wound site were hyphomycetes. A median of 2.1 (1.8-4.0) days passed from diagnosis to first antifungal treatment, and 3 patients died. CONCLUSIONS: Our study shows the challenges surrounding diagnosis and treatment of fungal infections secondary to trauma. Non-specific fungal infection symptoms, such as leukocytosis and fever, typically presented a week after injury. Vigilance for investigating risk factors and infection symptoms may help clinicians with more timely management of trauma patients with a severe fungal infection.

Comparing Outcomes of Patients With Idiopathic Subarachnoid Hemorrhage by Stratifying Perimesencephalic Bleeding Patterns.

BACKGROUND: To determine the clinical outcomes of perimesencephalic subarachnoid hemorrhages based on the computed tomography (CT) bleeding patterns. METHODS: This retrospective cohort study included: (1) patients (≥18 years) admitted to a comprehensive stroke center (January 2015-May 2018), (2) with angiography-negative, nontraumatic subarachnoid hemorrhage in a perimesencephalic or diffuse bleeding pattern, and (3) had CT imaging performed in ≤ 72 hours of symptom onset. Patients were stratified by location of bleeding on CT: Peri-1: focal prepontine hemorrhage; Peri-2: prepontine with suprasellar cistern +/- intraventricular extension; and diffuse. RESULTS: Of the 39 patients included, 13 were Peri-1, 11 were Peri-2, and 15 were diffuse. The majority were male (n = 26), with a mean (standard deviation) age of 55.3 (11.3) years, who often presented with headache (n = 37) and nausea (n = 28). Overall, patients in Peri-1 were significantly less likely to have hydrocephalus compared to Peri-2 and dSAH (P= .003), and 4 patients required an external ventricular drain. Five patients developed symptomatic vasospasm. Patients in Peri-1, compared to Peri-2 and diffuse, had a significantly shorter median neuro critical care unit length of stay (LOS) and hospital LOS. Most patients (n = 35) had a discharge modified Rankin Score between 0 and 2 with no significant differences found between groups. CONCLUSION: These data suggest that patients with the best clinical course were those in Peri-1, followed by Peri-2, and then diffuse. Because these patients often present with similar clinical signs, stratifying by hemorrhage pattern may help clinicians predict which patients with perimesencephalic subarachnoid hemorrhage develop complications.

Rethinking the definition of major trauma: The need for trauma intervention outperforms Injury Severity Score and Revised Trauma Score in 38 adult and pediatric trauma centers.

BACKGROUND: Patients' trauma burdens are a combination of anatomic damage, physiologic derangement, and the resultant depletion of reserve. Typically, Injury Severity Score (ISS) >15 defines major anatomic injury and Revised Trauma Score (RTS) <7.84 defines major physiologic derangement, but there is no standard definition for reserve. The Need For Trauma Intervention (NFTI) identifies severely depleted reserves (NFTI+) with emergent interventions and/or early mortality. We hypothesized NFTI would have stronger associations with outcomes and better model fit than ISS and RTS. METHODS: Thirty-eight adult and pediatric U.S. trauma centers submitted data for 88,488 encounters. Mixed models tested ISS greater than 15, RTS less than 7.84, and NFTI's associations with complications, survivors' discharge to continuing care, and survivors' length of stay (LOS). RESULTS: The NFTI had stronger associations with complications and LOS than ISS and RTS (odds ratios [99.5% confidence interval]: NFTI = 9.44 [8.46-10.53]; ISS = 5.94 [5.36-6.60], RTS = 4.79 [4.29-5.34]; LOS incidence rate ratios (99.5% confidence interval): NFTI = 3.15 [3.08-3.22], ISS = 2.87 [2.80-2.94], RTS = 2.37 [2.30-2.45]). NFTI was more strongly associated with continuing care discharge but not significantly more than ISS (relative risk [99.5% confidence interval]: NFTI = 2.59 [2.52-2.66], ISS = 2.51 [2.44-2.59], RTS = 2.37 [2.28-2.46]). Cross-validation revealed that in all cases NFTI's model provided a much better fit than ISS greater than 15 or RTS less than 7.84. CONCLUSION: In this multicenter study, NFTI had better model fit and stronger associations with the outcomes than ISS and RTS. By determining depletion of reserve via resource consumption, NFTI+ may be a better definition of major trauma than the standard definitions of ISS greater than 15 and RTS less than 7.84. Using NFTI may improve retrospective triage monitoring and statistical risk adjustments. LEVEL OF EVIDENCE: Prognostic, level IV.

A Multicenter Performance Improvement Program Uses Rural Trauma Filters for Benchmarking: An Evaluation of the Findings.

Colorado requires Level III and IV trauma centers to conduct a formal performance improvement program (PI), but provides limited support for program development. Trauma program managers and coordinators in rural facilities rarely have experience in the development or management of a PI program. As a result, rural trauma centers often face challenges in evaluating trauma outcomes adequately. Through a multidisciplinary outreach program, our Trauma System worked with a group of rural trauma centers to identify and define seven specific PI filters based on key program elements of rural trauma centers. This retrospective observational project sought to develop and examine these PI filters so as to enhance the review and evaluation of patient care. The project included 924 trauma patients from eight Level IV and one Level III trauma centers. Seven PI filters were retrospectively collected and analyzed by quarter in 2016: prehospital managed airway for patients with a Glasgow Coma Scale (GCS) score of less than 9; adherence to trauma team activation criteria; evidence of physician team leader presence within 20 min of activation; patient with a GCS score less than 9 in the emergency department (ED): intubated in less than 20 min; ED length of stay (LOS) less than 4 hr from patient arrival to transfer; adherence to admission criteria; documentation of GCS on arrival, discharge, or with change of status. There was a significantly increasing compliance trend toward appropriate documentation of GCS (p trend < .001) and a significantly decreasing compliance trend for ED LOS of less than 4 hr (p trend = .04). Moving forward, these data will be used to develop compliance thresholds, to identify areas for improvement, and create corrective action plans as necessary.

CARES: A Community-wide Collaboration Identifies Super-utilizers and Reduces Their 9-1-1 Call, Emergency Department, and Hospital Visit Rates.

BACKGROUND: A subset of individuals who inefficiently and frequently use emergency department (ED) services are called "super-utilizers." Our healthcare system is fragmented and complex, making it difficult for providers to identify super-utilizers and address their wide range of health issues. OBJECTIVE: The objective of our study was to evaluate a novel community-wide collaboration program called CARES (Community Assistance Referral and Education Services) designed to identify super-utilizers through local partnering organizations. CARES assists patients in developing their personal health and wellness goals, and navigates them away from 9-1-1 calls, emergency room visits, and hospital admissions, and toward more appropriate resources over 90 days. METHODS: This was a retrospective observational analysis of the CARES program. Data were collected from March 2013 to December 2015. The study population included: enrolled adults with non-compliance of medication or treatment; behavioral health problems; multiple 9-1-1 responses in a short period of time; three or more ED visits within six months; patients with multiple hospital admissions. Adults who were outside of the study period or had missing outcome information were excluded. The primary outcomes of this study were the median rate of 9-1-1 calls/month/person, ED and hospital visits/month/person. Wilcoxon rank-sum tests were used to compare changes between pre- vs. post-enrollment for each subject. RESULTS: A total of 441 subjects were included in this study. The majority of patients (64%) were female, 64% were white, and the median (IQR) age was 48 (35-62) years old. A total of 51% were on Medicaid and 69% identified behavioral health issues as their barriers to optimal health care. Between pre- and post-enrollment periods, the median (IQR) monthly rate of 9-1-1 calls, ED visits, and hospital admissions significantly decreased by 0.26 (-0.06, 0.90), 0.25 (-0.08, 0.71), and 0.18 (0.04, 0.53) (p < 0.001 for all). CONCLUSIONS: When health systems in a geographic area share data, they are better able to recognize patterns of overuse, and address them properly. This study demonstrated that a collaborative 90-day intervention identifying super-utilizers reduced the monthly rate of 9-1-1 calls, ED visits, and hospital admissions.

A standardized neurointerventional thrombectomy protocol leads to faster recanalization times.

BACKGROUND AND PURPOSE: Intra-arterial therapy (IAT) is most effective when performed rapidly after ischemic stroke onset. However, there are limited performance benchmarks in IAT and there is a scarcity of information on how to structure an effective IAT protocol and its impact on time to treatment. The objective of our study was to detail a standardized IAT protocol, and to assess its influence on time to treatment in ischemic stroke. METHODS: This was a retrospective observational study over 4 years at a comprehensive stroke center. A standardized IAT protocol was implemented in June 2013 that included pre-notifying the stroke team before hospital arrival, defining clinician roles, processing tasks in parallel, and standardizing IAT procedures. Three time metrics were examined and reported as median (IQR) minutes: arrival to CT imaging, CT to groin puncture, and puncture to recanalization. We compared these metrics in patients admitted before implementation (January 2012-May 2013) to patients admitted after (June 2013-December 2015) using Wilcoxon Mann-Whitney tests. RESULTS: 380 patients were included. After the protocol was implemented, there were significant reductions in time from arrival to CT (17 (14-21) vs 13 (11-19) min, p<0.001), CT to puncture (46 (30-82) vs 31 (23-54) min, p<0.001), and puncture to recanalization (65 (33-90) vs 37 (22-65) min, p<0.001). 60% of time was saved during puncture to recanalization. Significant reductions in time were observed during both normal working hours and off-hours. CONCLUSIONS: Implementation of a standardized protocol resulted in a significant reduction in time to recanalization for patients with an ischemic stroke. A standardized IAT protocol decreases time to recanalization when team roles are clearly defined, tasks are processed in parallel, and procedures are standardized.

Microglial priming through the lung-brain axis: the role of air pollution-induced circulating factors.

Air pollution is implicated in neurodegenerative disease risk and progression and in microglial activation, but the mechanisms are unknown. In this study, microglia remained activated 24 h after ozone (O3) exposure in rats, suggesting a persistent signal from lung to brain. Ex vivo analysis of serum from O3-treated rats revealed an augmented microglial proinflammatory response and ß-amyloid 42 (Aß42) neurotoxicity independent of traditional circulating cytokines, where macrophage-1 antigen-mediated microglia proinflammatory priming. Aged mice exhibited reduced pulmonary immune profiles and the most pronounced neuroinflammation and microglial activation in response to mixed vehicle emissions. Consistent with this premise, cluster of differentiation 36 (CD36)(-/-) mice exhibited impaired pulmonary immune responses concurrent with augmented neuroinflammation and microglial activation in response to O3 Further, aging glia were more sensitive to the proinflammatory effects of O3 serum. Together, these findings outline the lung-brain axis, where air pollutant exposures result in circulating, cytokine-independent signals present in serum that elevate the brain proinflammatory milieu, which is linked to the pulmonary response and is further augmented with age.-Mumaw, C.

Redox regulation of NF-κB p50 and M1 polarization in microglia.

Redox-signaling is implicated in deleterious microglial activation underlying CNS disease, but how ROS program aberrant microglial function is unknown. Here, the oxidation of NF-κB p50 to a free radical intermediate is identified as a marker of dysfunctional M1 (pro-inflammatory) polarization in microglia. Microglia exposed to steady fluxes of H2 O2 showed altered NF-κB p50 protein-protein interactions, decreased NF-κB p50 DNA binding, and augmented late-stage TNFα expression, indicating that H2 O2 impairs NF-κB p50 function and prolongs amplified M1 activation. NF-κB p50(-/-) mice and cultures exhibited a disrupted M2 (alternative) response and impaired resolution of the M1 response. Persistent neuroinflammation continued 1 week after LPS (1 mg/kg, IP) administration in the NF-κB p50(-/-) mice. However, peripheral inflammation had already resolved in both strains of mice. Treatment with the spin-trap DMPO mildly reduced LPS-induced 22 h TNFα in the brain in NF-κB p50(+/+) mice. Interestingly, DMPO failed to reduce and strongly augmented brain TNFα production in NF-κB p50(-/-) mice, implicating a fundamental role for NF-κB p50 in the regulation of chronic neuroinflammation by free radicals. These data identify NF-κB p50 as a key redox-signaling mechanism regulating the M1/M2 balance in microglia, where loss of function leads to a CNS-specific vulnerability to chronic inflammation.
