The effect of restrictive fluid management on outcomes among geriatric hip fractures: a retrospective cohort study at five level I trauma centers.

Restrictive fluid management (RFM) for hemodynamically unstable trauma patients has reduced mortality rates. The objective was to determine whether RFM benefits geriatric hip fracture patients, who are usually hemodynamically stable. Design: Retrospective propensity-matched study. Setting: Five Level I trauma centers (January 1, 2018-December 12, 2018). Patients: Geriatric patients (65 years or older) with hip fractures were included in this study. Patients with multiple injuries, nonoperative management, and preoperative blood products were excluded. Intervention: Patients were grouped by fluid volume (normal saline, lactated Ringer, dextrose, electrolytes, and medications) received preoperatively or ≤24 hours of arrival; patients with standard fluid management (SFM) received ≥150 mL and RFM <150 mL of fluids. Main Outcome Measurements: The primary outcomes were length of stay (LOS), delayed ambulation (>2 days postoperatively), and mortality. Paired Student t-tests, Wilcoxon paired rank sum tests, and McNemar tests were used; an α value of < 0.05 was considered statistically significant. Results: There were 523 patients (40% RFM, 60% SFM); after matching, there were 95 patients per arm. The matched patients were well-balanced, including no difference in time from arrival to surgery. RFM and SFM patients received a median of 80 mL and 1250 mL of preoperative fluids, respectively (P < 0.001). Postoperative fluid volumes were 1550 versus 2000 mL, respectively, (P = 0.73), and LOSs were similar between the two groups (5 versus 5 days, P = 0.83). Mortality and complications, including acute kidney injuries, were similar. Delayed ambulation rates were similar overall. When stratified by preinjury ambulation status, SFM was associated with delayed ambulation for patients not walking independently before injury (P = 0.01), but RFM was not (P = 0.09). Conclusions: RFM seems to be safe in terms of laboratory results, complications, and disposition. SFM may lead to delayed ambulation for patients who are not walking independently before injury.

Timing of venous thromboembolism chemoprophylaxis with major surgery of lower-extremity long bone fractures.

BACKGROUND: There is debate on the need to withhold chemical venous thromboembolism (VTE) prophylaxis in patients requiring major orthopedic surgery. We hypothesized that the incidence of clinically significant hemorrhage (CSH) does not differ by the timing of prophylaxis in such patients. METHODS: This was a multicenter, retrospective cohort study conducted at five US trauma centers that included trauma patients admitted between January 1, 2018, to March 1, 2020, requiring surgical fixation of the femoral shaft, hip, or tibia and received VTE chemoprophylaxis during the hospitalization. Exclusions were major and moderate head or spinal injuries, chronic anticoagulant use, or multiple long bone surgeries. Timing of VTE chemoprophylaxis was examined as four groups: (1) initiated preoperatively without interruption for surgery; (2) initiated preoperatively but held perioperatively; (3) initiated within 12 hours postoperatively; and (4) initiated >12 hours postoperatively. The primary outcome was incidence of CSH (%), defined as overt hemorrhage within 24 hours postoperative that was actionable. Multivariate logistic regression evaluated differences in CSH based on timing of VTE chemoprophylaxis. RESULTS: There were 786 patients, and 65 (8.3%) developed a CSH within 24 hours postoperatively. Nineteen percent of patients received chemoprophylaxis preoperatively without interruption for surgery, 13% had preoperative initiation but dose(s) were held for surgery, 21% initiated within 12 hours postoperatively, and 47% initiated more than 12 hours postoperatively. The incidence and adjusted odds of CSH were similar across groups (11.3%, 9.1%, 7.1%, and 7.3% respectively; overall p = 0.60). The incidence of VTE was 0.9% and similar across groups ( p = 0.47); however, six of seven VTEs occurred when chemoprophylaxis was delayed or interrupted. CONCLUSION: This study suggests that early and uninterrupted VTE chemoprophylaxis is safe and effective in patients undergoing major orthopedic surgery for long bone fractures. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Adherence to Antibiotic Recommendations and Infection Among Patients With Open Long-Bone Fractures: An Examination of Antibiotic Prioritization in Fracture Management.

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.

Does time to surgery for traumatic hip fracture impact the efficacy of fascia iliaca blocks? A brief report.

Objectives: Outcomes after traumatic hip fracture have shown to be significantly improved with timely surgical management. This study determined whether there were differences in efficacy of fascia iliaca compartment block (FICB) on pain outcomes in patients with hip fracture, once stratified by time to surgery. Methods: Trauma patients (55-90 years) admitted to five Level I/II trauma centers within 12 hours of hip fracture were included. Patients with coagulopathy, significant multi-trauma (injury severity score >16), bilateral hip fractures, and postoperative FICBs were excluded. The primary exposure was analgesia modality: adjunctive FICB or systemic analgesics (no FICB). Study endpoints were incidence of delirium through 48 hours postoperatively (%), preoperative and postoperative oral morphine equivalents (OMEs), and preoperative and postoperative pain (0-10 scale). Adjusted regression models were used to examine the effect of FICB on outcomes; all models were stratified by time from arrival to surgery, ≤24 hours (earlier surgery; n=413) and >24 hours (later surgery; n=143). Results: FICB use was similar with earlier and later surgery (70.2% vs 76.2%), and there were no demographic differences by utilization of FICB, by time to surgery. In the earlier surgery group, preoperative pain was lower for patients with FICB versus no FICB (3.6 vs 4.5, p<0.001), with no difference by FICB for delirium (OR 1.00, p>0.99) or OMEs (p=0.75 preoperative, p=0.91 postoperative). In the later surgery group, there was a nearly twofold reduction in preoperative OMEs with FICB than no FICB (25.5 mg vs 45.2 mg, p=0.04), with no differences for delirium (OR 4.21, p=0.18), pain scores (p=0.25 preoperative, p=0.27 postoperative), and postoperative OMEs (p=0.34). Conclusions: Compared with systemic analgesia, FICB resulted in improved pain scores at the preoperative assessment among patients with earlier surgery, whereas FICB reduced opioid consumption over the preoperative period only when surgery was later than 24 hours from arrival. Level of evidence: II, prospective, therapeutic.

Does altitude increase the risk of traumatic aortic injuries? A retrospective cohort study among six level I trauma centers in the United States.

BACKGROUND: Traumatic aortic injuries (TAIs) are rare but are associated with a high mortality. Prior studies have shown skiers and pilots, whose injuries occur at high altitudes, are at an increased risk for a TAI. The purpose of this study was to examine the effect of altitude on the incidence of TAIs across all causes of injury. METHODS: This retrospective cohort study at six Level I trauma centers (8/1/2016-1/1/2020) included adult blunt trauma patients with a chest or abdomen injury. High altitude injuries (> 5000 ft.) were compared to low altitude injuries (≤ 5000 ft.). The primary outcome was incidence of TAI. RESULTS: There were 8562 patients, 37% were at high altitude and 63% at low altitude. High altitude patients were older (p < 0.01), more often Caucasian (p < 0.01) and had a higher ISS (p < 0.01). There was a significantly greater incidence of TAI at high altitude than low altitude (1.5% vs. 1.1%, p = 0.01). The median altitude was significantly higher for patients with a TAI than for patients without a TAI (5100 ft. vs. 1400 ft., p = 0.01). After adjustment, high altitude patients had 2-fold [OR: 2.4 (1.6, 3.7)] greater odds of having a TAI than low altitude patients. CONCLUSION: TAIs were more prevalent among high altitude injuries. Providers should be aware of the increased incidence of TAIs at high altitudes particularly when there is a delay in diagnosis and transfer to a trauma center with appropriate resources to manage these critical injuries. TAI screening at high altitude trauma centers may improve survival rates.

Use of Cold-Stored Whole Blood is Associated With Improved Mortality in Hemostatic Resuscitation of Major Bleeding: A Multicenter Study.

OBJECTIVE: The aim of this study was to identify a mortality benefit with the use of whole blood (WB) as part of the resuscitation of bleeding trauma patients. BACKGROUND: Blood component therapy (BCT) is the current standard for resuscitating trauma patients, with WB emerging as the blood product of choice. We hypothesized that the use of WB versus BCT alone would result in decreased mortality. METHODS: We performed a 14-center, prospective observational study of trauma patients who received WB versus BCT during their resuscitation. We applied a generalized linear mixed-effects model with a random effect and controlled for age, sex, mechanism of injury (MOI), and injury severity score. All patients who received blood as part of their initial resuscitation were included. Primary outcome was mortality and secondary outcomes included acute kidney injury, deep vein thrombosis/pulmonary embolism, pulmonary complications, and bleeding complications. RESULTS: A total of 1623 [WB: 1180 (74%), BCT: 443(27%)] patients who sustained penetrating (53%) or blunt (47%) injury were included. Patients who received WB had a higher shock index (0.98 vs 0.83), more comorbidities, and more blunt MOI (all P <0.05). After controlling for center, age, sex, MOI, and injury severity score, we found no differences in the rates of acute kidney injury, deep vein thrombosis/pulmonary embolism or pulmonary complications. WB patients were 9% less likely to experience bleeding complications and were 48% less likely to die than BCT patients ( P <0.0001). CONCLUSIONS: Compared with BCT, the use of WB was associated with a 48% reduction in mortality in trauma patients. Our study supports the use of WB use in the resuscitation of trauma patients.

Validity between self-report and biochemical testing of cannabis and drugs among patients with traumatic injury: brief report.

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.

A multi-institutional prospective observational study to evaluate fascia iliaca compartment block (FICB) for preventing delirium in adults with hip fracture.

Objectives: Until recently, systemic opioids have been standard care for acute pain management of geriatric hip fracture; however, opioids increase risk for delirium. Fascia Iliaca compartment blocks (FICB) may be favored to systemic analgesia for reducing delirium, but this has not been well demonstrated. We evaluated the efficacy of adjunctive FICB versus systemic analgesia on delirium incidence, opioid consumption, and pain scores. Methods: This prospective, observational cohort study was performed in patients (55-90 years) with traumatic hip fracture admitted to five trauma centers within 12 hours of injury, enrolled between January 2019 and November 2020. The primary end point was development of delirium, defined by the Confusion Assessment Method tool, from arrival through 48 hours postoperatively, and analyzed with multivariate Firth logistic regression. Secondary end points were analyzed with analysis of covariance models and included preoperative and postoperative oral morphine equivalents and pain numeric rating scale scores. Results: There were 517 patients enrolled, 381 (74%) received FICB and 136 (26%) did not. Delirium incidence was 5.4% (n=28) and was similar for patients receiving FICB versus no FICB (FICB, 5.8% and no FICB, 4.4%; adjusted OR: 1.2 (95% CI 0.5 to 3.0), p=0.65). Opioid requirements were similar for patients receiving FICB and no FICB, preoperatively (p=0.75) and postoperatively (p=0.51). Pain scores were significantly lower with FICB than no FICB, preoperatively (4.2 vs 5.1, p=0.002) and postoperatively (2.9 vs 3.5, p=0.04). Conclusions: FICB demonstrated significant benefit on self-reported pain but without a concomitant reduction in opioid consumption. Regarding delirium incidence, these findings suggest clinical equipoise and the need for a randomized trial. Level of evidence: II-prospective, therapeutic.

Associations of Smoking With Delirium and Opioid Use in Older Adults With Traumatic Hip Fracture.

INTRODUCTION: Cigarette smoking is a risk factor for hip fractures, while risk factors for developing delirium include older age and preexisting cognitive impairment. We sought to determine whether smoking status is independently associated with delirium and pain outcomes. METHODS: This was a prospective, observational cohort study of 442 older adults (65 to 90 years) admitted for traumatic hip fracture at five trauma centers. The primary exposure was smoking status (n = 43, 10%). Additional risk factors included demographics, injury characteristics, and medical interventions. Delirium (primary) and analgesia-related complications were examined with multivariable logistic regression, while analysis of covariance models were used to examine preoperative and postoperative pain scores and opioid consumption (oral morphine equivalents). RESULTS: Smokers had significantly worse outcomes compared with nonsmokers: delirium incidence was 16.3% versus 5.0% (adjusted odds ratio, 4.23; P = 0.005), analgesia complications developed in 30.2% versus 14.8% (adjusted odds ratio, 2.63; P = 0.01), and postoperative opioid consumption was greater (53 mg versus 33 mg, adjusted P = 0.04). Adjusted pain scores were not different between groups. DISCUSSION: Smoking status is associated with markedly worse outcomes in older adults with traumatic hip fracture. Smoking status should be considered in pain management protocols and for early screening and delirium prevention methods. DATA AVAILABILITY: On reasonable request.

Characterization of peritoneal reactive ascites collected from acute appendicitis and small bowel obstruction patients.

BACKGROUND: Pathological abdominal adhesions can cause bowel obstructions. A history of appendectomy (appy) increases patient rehospitalization risk directly related to adhesions. To potentially identify strategies for adhesion treatment, we characterized reactive ascites (rA) collected during appy or adhesiolysis for small bowel obstruction (SBO). METHODS: This is a non-randomized, prospective observational study recruiting patients with non-perforated appendicitis or SBO from three Level 1 trauma centers in the United States. rA were analyzed via liquid chromatography-mass spectrometry (LC-MS) (n = 31), bead-based quantification cytokines and chemokines (n = 32) and soluble receptors (n = 30), and LC-MS metabolomics (n = 18). RESULTS: LC-MS showed that samples contained albumin, apolipoprotein A1, and transthyretin and that metabolites increased in SBO vs appy rA were biomarkers of oxidative stress. Multi-plex analyses showed levels of 17 cytokines/chemokines and 6 soluble receptors were significantly different in appy vs SBO rA. Top increased proteins in appy compared to SBO rA by 20.14-, 11.53-, and 8.18-fold were granulocyte-colony stimulating factor, C-X-C motif chemokine ligand 10, and interleukin-10, respectively. CONCLUSIONS: These data further define pro- and anti-inflammatory mediators and metabolites that may drive formation or perpetuate chronic abdominal adhesions. Future research is to further explore whether attenuation of these factors may decrease pathologic adhesion formation.

Significant variations in preoperative fluid resuscitation volumes delivered to elderly hip fracture patients at six level 1 trauma centers: an observational descriptive study.

OBJECTIVE: To describe the variations in administration of preoperative (preop) fluids and in the volumes of fluid administered among geriatric hip fracture patients requiring surgical repair. DESIGN: Observational descriptive. SETTING: Six Level 1 trauma centers. PATIENTS: A total of 595 patients aged ≥65 with ICD-10 codes indicating hip fracture and surgical repair were identified. Of these, 87.9% (n = 525) received preop fluid. The median volume of preop fluid delivered was 1500 mL (IQR: 1000-2250 mL). INTERVENTION: None. MAIN OUTCOME MEASURES: Receipt of preop fluids; median volume of fluid received. RESULTS: Receipt of preop fluid was significantly different by inter-hospital transfer, facility, BMI, hospital length of stay, and postop fluid volume. Age, sex, time to surgery, time to ambulation, and hospital disposition were not associated with preop fluid. There were significant differences in median preop fluid volumes by facility and postop fluid volume. CONCLUSION: This descriptive study of current practices among geriatric trauma patients with isolated hip fractures revealed significant differences in the use of preop fluid resuscitation and the resuscitation volumes administered. Treating facility may be the most substantial source of variation highlighting the need for a guideline on fluid resuscitation. These observed variations may be a result of patient characteristics or provider discretion and should be evaluated further.

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.

Are trauma research programs in academic and non-academic centers measured by equal standards? A survey of 137 level I trauma centers in the United States.

BACKGROUND: American College of Surgeons level I trauma center verification requires an active research program. This study investigated differences in the research programs of academic and non-academic trauma centers. METHODS: A 28-question survey was administered to ACS-verified level I trauma centers in 11/12/2020-1/7/2021. The survey included questions on center characteristics (patient volume, staff size), peer-reviewed publications, staff and resources dedicated to research, and funding sources. RESULTS: The survey had a 31% response rate: 137 invitations were successfully delivered via email, and 42 centers completed at least part of the survey. Responding level I trauma centers included 36 (86%) self-identified academic and 6 (14%) self-identified non-academic centers. Academic and non-academic centers reported similar annual trauma patient volume (2190 vs. 2450), number of beds (545 vs. 440), and years of ACS verification (20 vs. 14), respectively. Academic centers had more full-time trauma surgeons (median 8 vs 6 for non-academic centers) and general surgery residents (median 30 vs 7) than non-academic centers. Non-academic centers more frequently ranked trauma surgery (100% vs. 36% academic), basic science (50% vs. 6% academic), neurosurgery (50% vs. 14% academic), and nursing (33% vs. 0% academic) in the top three types of studies conducted. Academic centers were more likely to report non-profit status (86% academic, 50% non-academic) and utilized research funding from external governmental or non-profit grants more often (76% vs 17%). CONCLUSIONS: Survey results suggest that academic centers may have more physician, resident, and financial resources available to dedicate to trauma research, which may make fulfillment of ACS level I research requirements easier. Structural and institutional changes at non-academic centers, such as expansion of general surgery resident programs and increased pursuit of external grant funding, may help ensure that academic and non-academic sites are equally equipped to fulfill ACS research criteria.

Recalibrating the Glasgow Coma Score as an Age-Adjusted Risk Metric for Neurosurgical Intervention.

BACKGROUND: The Glasgow Coma Scale (GCS) score is the most frequently used neurologic assessment in traumatic brain injury (TBI). The risk for neurosurgical intervention based on GCS is heavily modified by age. The objective is to create a recalibrated Glasgow Coma Scale (GCS) score that accounts for an interaction by age and determine the predictive performance of the recalibrated GCS (rGCS) compared to the standard GCS for predicting neurosurgical intervention. METHODS: This retrospective cohort study utilized the National Trauma Data Bank and included all patients admitted from 2010-2015 with TBI (ICD9 diagnosis code 850-854.19). The study population was divided into 2 subsets: a model development dataset (75% of patients) and a model validation dataset (remaining 25%). In the development dataset, logistic regression models were used to calculate conditional probabilities of having a neurosurgical intervention for each combination of age and GCS score, to develop a point-based risk score termed the rGCS. Model performance was examined in the validation dataset using area under the receiver operating characteristic (AUROC) curves and calibration plots. RESULTS: There were 472,824 patients with TBI. The rGCS ranged from 1-15, where rGCS 15 denotes the baseline risk for neurosurgical intervention (4.4%) and rGCS 1 represents the greatest risk (62.6%). In the validation dataset there was a statistically significant improvement in predictive performance for neurosurgical intervention for the rGCS compared to the standard GCS (AUROC: 0.71 versus 0.67, difference, -0.04, P<0.001), overall and by trauma level designation. The rGCS was better calibrated than the standard GCS score. CONCLUSIONS: The relationship between GCS score and neurosurgical intervention is significantly modified by age. A revision to the GCS that incorporates age, the rGCS, provides risk of neurosurgical intervention that has better predictive performance than the standard ED GCS score.

Effect of the COVID-19 pandemic on the ability of level 1 trauma centers to meet American College of Surgeons research requirements.

INTRODUCTION: The COVID-19 pandemic has had major effects on hospitals' ability to perform scientific research while providing patient care and minimizing virus exposure and spread. Many non-COVID-19 research has been halted, and funding has been diverted to COVID-19 research and away from other areas. METHODS: A 28-question survey was administered to all level 1 trauma centers in the USA that included questions about how the pandemic affected the trauma centers' ability to fulfill the volume and research requirements of level 1 verification by the American College of Surgeons (ACS). RESULTS: The survey had a 29% response rate (40/137 successful invitations). Over half of respondents (52%) reported reduced trauma admissions during the pandemic, and 7% reported that their admissions dropped below the volume required for level 1 verification. Many centers diverted resources from research during the pandemic (44%), halted ongoing consenting studies (33%), and had difficulty fulfilling research requirements because of competing clinical priorities (40%). DISCUSSION: Results of this study show a need for flexibility in the ACS verification process during the COVID-19 pandemic, potentially including reduction of the required admissions and/or research publication volumes. LEVEL OF EVIDENCE: Level IV, cross-sectional study.

Multicenter study of US trauma centers examining the effect of the COVID-19 pandemic on injury causes, diagnoses and procedures.

BACKGROUND: The COVID-19 pandemic resulted in nationwide social distancing and shelter-in-place orders meant to curb transmission of the SARS-CoV-2 virus. The effect of the pandemic on injury patterns has not been well described in the USA. The study objective is to determine the effect of the COVID-19 pandemic on the distribution and determinants of traumatic injuries. METHODS: This retrospective multi-institutional cohort study included all hospital admissions for acute traumatic injury at six community level I trauma centers. Descriptive statistics were used to compare injury causes, diagnoses and procedures over two similar time periods: prepandemic (March 11-June 30, 2019) and pandemic (March 11-June 30, 2020). RESULTS: There were 7308 trauma patients included: 3862 (53%) prepandemic and 3446 (47%) during the pandemic. Cause of injury significantly differed by period (p<0.001). During the pandemic, there were decreases in motor vehicle crashes (from 17.0% to 14.0%, p<0.001), worksite injuries (from 5.2% to 4.1%, p=0.02), pedestrian injuries (from 3.0% to 2.2%, p=0.02) and recreational injuries (from 3.0% to 1.7%, p<0.001), while there were significant increases in assaults (6.9% to 8.5%, p=0.01), bicycle crashes (2.8% to 4.2%, p=0.001) and off-road vehicle injuries (1.8% to 3.0%, p<0.001). There was no change by study period in falls, motorcycle injuries, crush/strikes, firearm and self-inflicted injuries, and injuries associated with home-improvement projects. Injury diagnoses differed between time periods; during the pandemic, there were more injury diagnoses to the head (23.0% to 27.3%, p<0.001) and the knee/leg (11.7% to 14.9%, p<0.001). There were also increases in medical/surgical procedures (57.5% to 61.9%, p<0.001), administration of therapeutics/blood products (31.4% to 34.2%, p=0.01) and monitoring (11.0% to 12.9%, p=0.01). DISCUSSION: Causes of traumatic injury, diagnoses, and procedures were significantly changed by the pandemic. Trauma centers must adjust to meet the changing demands associated with altered injury patterns, as they were associated with increased use of hospital resources. LEVEL OF EVIDENCE: III (epidemiological).

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.

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.

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.

Associations of Antithrombotic Timing and Regimen with Ischemic Stroke and Bleeding Complications in Blunt Cerebrovascular Injury.

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% (n = 14), with most strokes (64%, n = 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 (P = .78), transfusion (P = .43), or ICH (P = .96). Similarly, time on antiplatelets (P = .54, P = .65, P = .60) and time on combination therapy (P = .96, P = .38, P = .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.
