RESUMEN

Importance: Wide variations exist in traumatic brain injury (TBI) management strategies and transfer guidelines across the country. Objective: To assess the outcomes of patients with TBI transferred to the American College of Surgeons (ACS) level I (LI) or level II (LII) trauma centers (TCs) on a nationwide scale. Design, Setting, and Participants: In this secondary analysis of the ACS Trauma Quality Improvement Program database (2017 to 2020), adult patients with isolated TBI (nonhead abbreviated injury scale = 0) with intracranial hemorrhage (ICH) who were transferred to LI/LII TCs we re included. Data were analyzed from January 1, 2017, through December 31, 2020. Main Outcomes and Measures: Outcomes were rates of head computed tomography scans, neurosurgical interventions (cerebral monitors, craniotomy/craniectomy), hospital length of stay, and mortality. Descriptive statistics and hierarchical mixed-model regression analyses were performed. Results: Of 117 651 patients with TBI with ICH managed at LI/LII TCs 53 108; (45.1%; 95% CI, 44.8%-45.4%) transferred from other centers were identified. The mean (SD) age was 61 (22) years and 30 692 were male (58%). The median (IQR) Glasgow Coma Scale score on arrival was 15 (14-15); 5272 patients had a Glasgow Coma Scale score of 8 or less on arrival at the receiving trauma center (10%). A total of 30 973 patients underwent head CT scans (58%) and 2144 underwent repeat head CT scans at the receiving TC (4%). There were 2124 patients who received cerebral monitors (4%), 6862 underwent craniotomy/craniectomy (13%), and 7487 received mechanical ventilation (14%). The median (IQR) hospital length of stay was 2 (1-5) days and the mortality rate was 6.5%. There were 9005 patients (17%) who were discharged within 24 hours and 19 421 (37%) who were discharged within 48 hours of admission without undergoing any neurosurgical intervention. Wide variations between and within trauma centers in terms of outcomes were observed in mixed-model analysis. Conclusions: In this study, nearly half of the patients with TBI managed at LI/LII TCs were transferred from lower-level hospitals. Over one-third of these transferred patients were discharged within 48 hours without any interventions. These findings indicate the need for systemwide guidelines to improve health care resource use and guide triage of patients with TBI.

RESUMEN

INTRODUCTION: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a temporizing hemorrhage control intervention, but its inevitable effect on time to operating room (OR) has not been assessed. The aim of our study is to assess the impact of undergoing REBOA before surgery (RBS) on time to definitive hemorrhage control surgery. METHODS: In this retrospective analysis of 2017-2021 ACS-TQIP database, all adult (≥18 years) patients who underwent emergency hemorrhage control laparotomy (≤4 hours of admission) and received early blood products (≤4 hours) were included, and patients with severe head injury (Head-abbreviated injury score > 2) were excluded. Patients were stratified into those who did (RBS) vs those who did not undergo REBOA before surgery (No-RBS). Primary outcome was time to laparotomy. Secondary outcomes were complications and mortality. Multivariable linear and binary logistic regression analyses were performed to identify the independent associations between RBS and outcomes. RESULTS: A total of 32,683 patients who underwent emergency laparotomy were identified (RBS: 342; No-RBS: 32,341). The mean age was 39 (16) years, 78% were male, mean SBP was 107 (34) mmHg, and the median injury severity score was 21 [14-29]. The median time to emergency hemorrhage control surgery was 50 [32-85] minutes. Overall complication rate was 16% and mortality was 19%. On univariate analysis, RBS group had longer time to surgery (RBS 56 [41-89] vs No-RBS 50 [32-85] minutes, P < 0.001). On multivariable analysis, RBS was independently associated with a longer time to hemorrhage control surgery (ß + 14.5 [95%CI 7.8-21.3], P < 0.001), higher odds of complications (aOR = 1.72, 95%CI = 1.27-2.34, P < 0.001), and mortality (aOR = 3.42, 95%CI = 2.57-4.55, P < 0.001). CONCLUSION: REBOA is independently associated with longer time to OR for hemorrhaging trauma patients with an average delay of 15 minutes. Further research evaluating center-specific REBOA volume and utilization practices, and other pertinent system factors, may help improve both time to REBOA as well as time to definitive hemorrhage control across US trauma centers. LEVEL OF EVIDENCE: III. STUDY TYPE: Epidemiologic.

RESUMEN

INTRODUCTION: This study aimed to develop and validate Futility of Resuscitation Measure (FoRM) for predicting the futility of resuscitation among older adult trauma patients. METHODS: This is a retrospective analysis of the American College of Surgeons-Trauma Quality Improvement Program database (2017-2018) (derivation cohort) and American College of Surgeons level I trauma center database (2017-2022) (validation cohort). We included all severely injured (injury severity score >15) older adult (aged ≥60 y) trauma patients. Patients were stratified into decades of age. Injury characteristics (severe traumatic brain injury [Glasgow Coma Scale ≤ 8], traumatic brain injury midline shift), physiologic parameters (lowest in-hospital systolic blood pressure [≤1 h], prehospital cardiac arrest), and interventions employed (4-h packed red blood cell transfusions, emergency department resuscitative thoracotomy, resuscitative endovascular balloon occlusion of the aorta, emergency laparotomy [≤2 h], early vasopressor requirement [≤6 h], and craniectomy) were identified. Regression coefficient-based weighted scoring system was developed using the Schneeweiss method and subsequently validated using institutional database. RESULTS: A total of 5562 patients in derivation cohort and 873 in validation cohort were identified. Mortality was 31% in the derivation cohort and FoRM had excellent discriminative power to predict mortality (area under the receiver operator characteristic = 0.860; 95% confidence interval [0.847-0.872], P < 0.001). Patients with a FoRM score of >16 had a less than 10% chance of survival, while those with a FoRM score of >20 had a less than 5% chance of survival. In validation cohort, mortality rate was 17% and FoRM had good discriminative power (area under the receiver operator characteristic = 0.76; 95% confidence interval [0.71-0.80], P < 0.001). CONCLUSIONS: FoRM can reliably identify the risk of futile resuscitation among older adult patients admitted to our level I trauma center.

RESUMEN

INTRODUCTION: There is a lack of data on the outcomes of thoracic damage control surgery (TDCS). This study aimed to describe the characteristics and outcomes of patients undergoing TDCS. METHODS: This is a retrospective analysis of the American College of Surgeons-Trauma Quality Improvement Program database (2017-2021). All trauma patients who underwent emergency thoracotomy and packing with temporary closure were included. Patients were stratified based on the age groups (pediatric [<18 y], adults [18-64 y], and older adults [≥65 y]). Our primary outcome measures included 6-h, 24-h, and in-hospital mortality. Secondary outcomes were major complications. RESULTS: We identified 14,192 thoracotomies, out of which 213 underwent TDCS (pediatric [n = 17], adults [n = 175], and older adults [n = 21]). The mean (SD) age was 37 (18), and 86% were male. The mean shock index was 1.1 (0.4) on presentation with a median [IQR] Glasgow Coma Scale of 4 [3-14], and 22.1% had a prehospital cardiac arrest. The study population was profoundly injured with a median injury severity scoreand chest-abbreviated injury scale of 26 [17-38] and 4 [3-5], respectively, with lung (76.5%) being the most injured intrathoracic organs. Overall, the rates of 6-h, 24-h, and in-hospital mortality were 22.5%, 33%, and 53%, respectively, and 51% developed major complications. There was no significant difference in terms of in-hospital mortality (P = 0.800) and major complications (0.416) among pediatrics, adults, and older adults. CONCLUSIONS: One in three patients undergoing TDCS die within the first 24 h, and more than half of them develop major complications and die in the hospital, with no difference among pediatric, adults, and older adults. Future efforts should be directed to improve the survival of these severely injured, metabolically depleted, challenging patients.

RESUMEN

ABSTRACT: Purpose: To evaluate the dose-dependent effect of whole blood (WB) on the outcomes of civilian trauma patients with hemorrhagic shock. Methods: We performed a 2-year (2020-2021) retrospective analysis of the ACS-TQIP dataset. Adult (≥18) trauma patients with a shock index (SI) >1 who received at least 5 units of PRBC and one unit of WB within the first 4 h of admission were included. Primary outcomes were 6-h, 24-h, and in-hospital mortality. Secondary outcomes were major complications and hospital and intensive care unit length of stay. Results: A total of 830 trauma patients with a mean (SD) age of 38 (16) were identified. The median [IQR] 4-h WB and PRBC requirements were 2 [2-4] U and 10 [7-15] U, respectively, with a median WB:RBC ratio of 0.2 [0.1-0.3]. Every 0.1 increase in WB:RBC ratio was associated with decreased odds of 24-h mortality (aOR: 0.916, P = 0.035) and in-hospital mortality (aOR: 0.878, P < 0.001). Youden's index identified 0.25 (1 U of WB for every 4 U of PRBC) as the optimal WB:PRBC ratio to reduce 24-h mortality. High ratio (≥0.25) group had lower adjusted odds of 24-h mortality (aOR: 0.678, P = 0.021) and in-hospital mortality (aOR: 0.618, P < 0.001) compared to the low ratio group. Conclusions: A higher WB:PRBC ratio was associated with improved early and late mortality in trauma patients with hemorrhagic shock. Given the availability of WB in trauma centers across the United States, at least one unit of WB for every 4 units of packed red blood cells may be administered to improve the survival of hemorrhaging civilian trauma patients.

RESUMEN

INTRODUCTION: Whole blood (WB) has recently gained increased popularity as an adjunct to the resuscitation of hemorrhaging civilian trauma patients. We aimed to assess the nationwide outcomes of using WB as an adjunct to component therapy (CT) versus CT alone in resuscitating geriatric trauma patients. METHODS: We performed a 5-y (2017-2021) retrospective analysis of the Trauma Quality Improvement Program. We included geriatric (age, ≥65 y) trauma patients presenting with hemorrhagic shock (shock index >1) and requiring at least 4 units of packed red blood cells in 4 h. Patients with severe head injuries (head Abbreviated Injury Scale ≥3) and transferred patients were excluded. Patients were stratified into WB-CT versus CT only. Primary outcomes were 6-h, 24-h, and in-hospital mortality. Secondary outcomes were major complications. Multivariable regression analysis was performed, adjusting for potential confounding factors. RESULTS: A total of 1194 patients were identified, of which 141 (12%) received WB. The mean ± standard deviation age was 74 ± 7 y, 67.5% were male, and 83.4% had penetrating injuries. The median [interquartile range] Injury Severity Score was 19 [13-29], with no difference among study groups (P = 0.059). Overall, 6-h, 24-h, and in-hospital mortality were 16%, 23.1%, and 43.6%, respectively. On multivariable regression analysis, WB was independently associated with reduced 24-h (odds ratio, 0.62 [0.41-0.94]; P = 0.024), and in-hospital mortality (odds ratio, 0.60 [0.40-0.90]; P = 0.013), but not with major complications (odds ratio, 0.78 [0.53-1.15]; P = 0.207). CONCLUSIONS: Transfusion of WB as an adjunct to CT is associated with improved early and overall mortality in geriatric trauma patients presenting with severe hemorrhage. The findings from this study are clinically important, as this is an essential first step in prioritizing the selection of WB resuscitation for geriatric trauma patients presenting with hemorrhagic shock.

RESUMEN

INTRODUCTION: Interfacility transfer to higher levels of care is becoming increasingly common. This study aims to evaluate the association between transfer to higher levels of care and prolonged transfer times with outcomes of severely injured geriatric trauma patients compared to those who are managed definitively at lower-level trauma centers. METHODS: Severely injured (Injury Severity Score >15) geriatric (≥60 y) trauma patients in the 2017-2018 American College of Surgeons Trauma Quality Improvement Program database managing at an American College of Surgeons/State Level III trauma center or transferring to a level I or II trauma center were included. Outcome measures were 24-h and in-hospital mortality and major complications. RESULTS: Forty thousand seven hundred nineteen patients were identified. Mean age was 75 ± 8 y, 54% were male, 98% had a blunt mechanism of injury, and the median Injury Severity Score was 17 [16-21]. Median transfer time was 112 [79-154] min, and the most common transport mode was ground ambulance (82.3%). Transfer to higher levels of care within 90 min was associated with lower 24-h mortality (adjusted odds ratio [aOR]: 0.493, P < 0.001) and similar odds of in-hospital mortality as those managed at level III centers. However, every 30-min delay in transfer time beyond 90 min was progressively associated with increased odds of 24-h (aOR: 1.058, P < 0.001) and in-hospital (aOR: 1.114, P < 0.001) mortality and major complications (aOR: 1.127, P < 0.001). CONCLUSIONS: Every 30-min delay in interfacility transfer time beyond 90 min is associated with 6% and 11% higher risk-adjusted odds of 24-h and in-hospital mortality, respectively. Estimated interfacility transfer time should be considered while deciding about transferring severely injured geriatric trauma patients to a higher level of care.

RESUMEN

INTRODUCTION: There is a paucity of large-scale data on the factors that suggest an impending or underlying extremity pediatric acute compartment syndrome (ACS). In addition, literature regarding the timing of operative fixation and the risk of ACS is mixed. We aimed to describe the factors associated with pediatric ACS. METHODS: Analysis of 2017-2019 Trauma Quality Improvement Program. We included patients aged <18 y diagnosed with upper extremity (UE) and lower extremity (LE) fractures. Burns and insect bites/stings were excluded. Multivariable regression analyses were performed to identify the predictors of ACS. RESULTS: 61,537 had LE fractures, of which 0.5% developed ACS. 76,216 had UE fractures, of which 0.16% developed ACS. Multivariable regression analyses identified increasing age, male gender, motorcycle collision, and pedestrian struck mechanisms of injury, comminuted and open fractures, tibial and concurrent tibial and fibular fractures, forearm fractures, and operative fixation as predictors of ACS (P value <0.05). Among LE fractures, 34% underwent open reduction internal fixation (time to operation = 14 [8-20] hours), and 2.1% underwent ExFix (time to operation = 9 [4-17] hours). Among UE fractures, 54% underwent open reduction internal fixation (time to operation = 11 [6-16] hours), and 1.9% underwent ExFix (time to operation = 9 [4-14] hours). Every hour delay in operative fixation of UE and LE fractures was associated with a 0.4% increase in the adjusted odds of ACS (P value <0.05). CONCLUSIONS: Our results may aid clinicians in recognizing children who are "at risk" for ACS. Future studies are warranted to explore the optimal timing for the operative fixation of long bone fractures to minimize the risk of pediatric ACS.

RESUMEN

OBJECTIVE: To identify the modifiable and non-modifiable risk factors associated with post-intubation hypotension (PIH) among trauma patients who required endotracheal intubation (ETI) in the trauma bay. SUMMARY BACKGROUND DATA: ETI has been associated with hemodynamic instability, termed PIH, yet its risk factors in trauma patients remain under-investigated. METHODS: This is a prospective observational study at a level I trauma center over 4 years (2019-2022). All adult (≥18) trauma patients requiring ETI in the trauma bay were included. Blood pressure was monitored both pre- and post-intubation. Multivariable logistic regression analysis was performed to identify the modifiable and non-modifiable factors associated with PIH. RESULTS: 708 patients required ETI in the trauma bay, of which, 435 (61.4%) developed PIH. The mean (SD) age was 43 (21) and 71% were male. Median [IQR] arrival GCS was 7 [3-13]. Patients who developed PIH had a lower mean (SD) pre-intubation SBP (118 (46) vs. 138 (28), P<0.001) and higher median [IQR] ISS (27 [21-38] vs. 21 [9-26], P<0.001). Multivariable regression analysis identified BMI>25, increasing ISS, penetrating injury, spinal cord injury, Pre-intubation PRBC requirements, and diabetes mellitus as non-modifiable risk factors associated with increased odds of PIH. In contrast, pre-intubation administration of 3% hypertonic saline and vasopressors were identified as the modifiable factors significantly associated with reduced PIH. CONCLUSION: More than half of the patients requiring ETI in the trauma bay developed PIH. This study identified modifiable and non-modifiable risk factors that influence the development of PIH, which will help physicians when considering ETI upon patient arrival. LEVEL OF EVIDENCE: Level III, Prognostic Study.

RESUMEN

INTRODUCTION: Initial interaction with health care system presents an important opportunity to provide substance use disorder (SUD) rehabilitation in the form of mental health services (MHSs). This study aims to identify predictors of receipt of MHSs among adult trauma patients with SUD and positive drug screen. METHODS: In this analysis of 2017-2021 American College of Surgeons-Trauma Quality Improvement Program (ACS TQIP), adult(≥18 y) patients with SUD and positive drug screen who survived the hospital admission were included. Outcomes measure was the receipt of MHS. Poisson regression analysis with clustering by facility was performed to identify independent predictors of receipt of MHS. RESULTS: 128,831 patients were identified of which 3.4% received MHS. Mean age was 41 y, 76% were male, 63% were White, 25% were Black, 12% were Hispanic, and 82% were insured. Median injury severity score was 9, and 54% were managed at an ACS level I trauma center. On regression analysis, female gender (aOR = 1.17, 95% CI = 1.09-1.25), age ≥65 y (aOR = 0.98, 95% CI = 0.97-0.99), White race (aOR = 1.37, 95% CI = 1.28-1.47), Hispanic ethnicity (aOR = 0.84, 95% CI = 0.76-0.93), insured status (aOR = 1.22, 95% CI = 1.13-1.33), and management at ACS level I trauma centers (aOR = 1.47, 95% CI = 1.38-1.57) were independent predictors of receipt of MHS. CONCLUSIONS: Race, ethnicity, and socioeconomic factors predict the receipt of MHS in trauma patients with SUD and positive drug screens. It is unknown if these disparities affect the long-term outcomes of these vulnerable patients. Further research is warranted to expand on the contributing factors leading to these disparities and possible strategies to address them.

RESUMEN

INTRODUCTION: We aimed to examine impact of trauma center (TC) surgical stabilization of rib fracture (SSRF) volume on outcomes of patients undergoing SSRF. METHODS: Blunt rib fracture patients who underwent SSRF were included from ACS-TQIP2017-2021. TCs were stratified according to tertiles of SSRF volume:low (LV), middle, and high (HV). Outcomes were time to SSRF, respiratory complications, prolonged ventilator use, mortality. RESULTS: 16,872 patients were identified (LV:5470,HV:5836). Mean age was 56 years, 74% were male, median thorax-AIS was 3. HV centers had a lower proportion of patients with flail chest (HV41% vs LV50%), pulmonary contusion (HV44% vs LV52%) and had shorter time to SSRF(HV58 vs LV76 â€‹h), less respiratory complications (HV3.2% vs LV4.5%), prolonged ventilator use (HV15% vs LV26%), mortality (HV2% vs LV2.6%) (all p â€‹< â€‹0.05). On multivariable regression analysis, HV centers were independently associated with reduced time to SSRF(ߠ​= â€‹-18.77,95%CI â€‹= â€‹-21.30to-16.25), respiratory complications (OR â€‹= â€‹0.67,95%CI â€‹= â€‹0.49-0.94), prolonged ventilator use (OR â€‹= â€‹0.49,95%CI â€‹= â€‹0.41-0.59), but not mortality. CONCLUSIONS: HV SSRF centers have improved outcomes, however, there are variations in threshold for SSRF and indications must be standardized. LEVEL OF EVIDENCE: Level III. STUDY TYPE: Therapeutic/Care Management.

RESUMEN

With a rapidly aging worldwide population, the care of geriatric trauma patients will be at the forefront of every career in Trauma and Acute Care Surgery. The unique intersection of advanced age, comorbidities, frailty, and physiologic changes presents a challenge in the care of elderly injured patients. It is well established that increasing age is associated with higher mortality and worse outcomes after injury, but it is also clear that there is room for improvement in the management of this special patient population.

RESUMEN

INTRODUCTION: This study aims to evaluate effect of 4-factor PCC on outcomes of severe TBI patients on preinjury anticoagulants undergoing craniotomy/craniectomy. METHODS: In this analysis of 2018-2020 ACS-TQIP, patients with isolated blunt severe TBI (Head-AIS≥3, nonhead-AIS<2) using preinjury anticoagulants who underwent craniotomy/craniectomy were identified and stratified into PCC and No-PCC groups. Outcomes were time to surgery and mortality. Multivariable binary logistic and linear regression analyses were performed. RESULTS: 1598 patients were identified (PCC-107[7 %], No-PCC-1491[93 %]). Mean age was 74(11) years, 65 % were male, median head AIS was 4. Median time to PCC administration was 109 â€‹min. On univariable analysis, PCC group had shorter time to surgery (PCC-341, No-PCC-620 â€‹min, p â€‹= â€‹0.002), but higher mortality (PCC35 %, No-PCC21 %,p â€‹= â€‹0.001). On regression analysis, PCC was independently associated with shorter time to surgery (ߠ​= â€‹-1934,95 %CI â€‹= â€‹-3339to-26), but not mortality (aOR â€‹= â€‹0.70,95 %CI â€‹= â€‹0.14-3.62). CONCLUSION: PCC may be a safe adjunct for urgent reversal of coagulopathy in TBI patients using preinjury anticoagulants.

RESUMEN

INTRODUCTION: It remains unclear whether geriatrics benefit from care at higher-level trauma centers (TCs). We aimed to assess the impact of the TC verification level on frail geriatric trauma patients' outcomes. We hypothesized that frail patients cared for at higher-level TCs would have improved outcomes. STUDY DESIGN: Patients ≥65 years were identified from the Trauma Quality Improvement Program (TQIP) database (2017-2019). Patients transferred, discharged from emergency department (ED), and those with head abbreviated injury scale >3 were excluded. 11-factor modified frailty index was utilized. Propensity score matching (1:1) was performed. Outcomes included discharge to skilled nursing facility or rehab (SNF/rehab), withdrawal of life-supporting treatment (WLST), mortality, complications, failure-to-rescue, intensive care unit (ICU) admission, hospital length of stay (LOS), and ventilator days. RESULTS: 110,680 patients were matched (Frail:55,340, Non-Frail:55,340). Mean age was 79 (7), 90% presented following falls, and median ISS was 5 [2-9]. Level-I/II TCs had lower rates of discharge to SNF/rehab (52.6% vs. 55.8% vs. 60.9%; p < 0.001), failure-to-rescue (0.5% vs. 0.4% vs. 0.6%;p = 0.005), and higher rates of WLST (2.4% vs. 2.1% vs. 0.3%; p < 0.001) compared to level-III regardless of injury severity and frailty. Compared to Level-III centers, Level-I/II centers had higher complications among moderate-to-severely injured patients (4.1% vs. 3.3% vs. 2.7%; p < 0.001), and lower mortality only among frail patients regardless of injury severity (1.8% vs. 1.5% vs. 2.6%; p < 0.001). Patients at Level-I TCs were more likely to be admitted to ICU, and had longer hospital LOS and ventilator days compared to Level-II and III TCs (p < 0.05). CONCLUSION: Frailty may play an important role when triaging geriatric trauma patients. In fact, the benefit of care at higher-level TCs is particularly evident for patients who are frail. Level III centers may be underperforming in providing access to palliative and end-of-life care.

RESUMEN

BACKGROUND: Frailty is associated with poor outcomes in trauma patients. However, the spectrum of physiologic deficits, once a patient is identified as frail, is unknown. The aim of this study was to assess the dynamic association between increasing frailty and outcomes among frail geriatric trauma patients. METHODS: This is a secondary analysis of the American Association of Surgery for Trauma Frailty Multi-institutional Trial. Patients 65 years or older presenting to one of the 17 trauma centers over 3 years (2019-2022) were included. Frailty was assessed within 24 hours of presentation using the Trauma-Specific Frailty Index (TSFI) questionnaire. Patients were stratified by TSFI score into six groups: nonfrail (<0.12), Grade I (0.12-0.19), Grade II (0.20-0.29), Grade III (0.30-0.39), Grade IV (0.40-0.49), and Grade V (0.50-1). Our Outcomes included in-hospital and 3-month postdischarge mortality, major complications, readmissions, and fall recurrence. Multivariable regression analyses were performed. RESULTS: There were 1,321 patients identified. The mean (SD) age was 77 years (8.6 years) and 49% were males. Median [interquartile range] Injury Severity Score was 9 [5-13] and 69% presented after a low-level fall. Overall, 14% developed major complications and 5% died during the index admission. Among survivors, 1,116 patients had a complete follow-up, 16% were readmitted within 3 months, 6% had a fall recurrence, 7% had a complication, and 2% died within 3 months postdischarge. On multivariable regression, every 0.1 increase in the TSFI score was independently associated with higher odds of index-admission mortality and major complications, and 3 months postdischarge mortality, readmissions, major complications, and fall recurrence. CONCLUSION: The frailty syndrome goes beyond a binary stratification of patients into nonfrail and frail and should be considered as a spectrum of increasing vulnerability to poor outcomes. Frailty scoring can be used in developing guidelines, patient management, prognostication, and care discussions with patients and their families. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

RESUMEN

BACKGROUND: Adequate pain control is a critical component of rib fracture management. Our study aimed to evaluate the in-hospital and post-discharge outcomes of geriatric rib fracture patients who received paravertebral nerve block (PVNB) versus epidural analgesia (EA) on a national level. METHODS: We performed a 5-year (2011-15) retrospective analysis of the Nationwide Readmission database. We included all the geriatric (≥65 years) blunt trauma patients with rib fractures who received a paravertebral nerve block (PVNB) or Epidural analgesia (EA) for chest injuries. We excluded patients who were dead on arrival, those with head AIS≥3, spine AIS >0, and those with cognitive impairment. Patients were stratified into two groups (PVNB and EA). A propensity score matching (1:2) was performed, and the two groups were compared. Our outcomes included delirium, hospital length of stay (LOS), 90-day readmissions, 90-day mechanical ventilation, and initial and 90-day mortality. RESULTS: A total of 2,855 geriatric rib fracture patients were identified, out of which 352 (12 %) received PVNB and 2,503 (87 %) received EA. The mean (SD) age was 78 (8) years and 53 % were female. A total of 1,041 patients were matched (PVNB=347, EA=694 patients). The median [IQR] Injury severity score was 9 [3-15], median chest AIS was 3 [2-4], and 70 % had ≥3 rib fractures. The total mortality during index admission was 6 %, 13 % experienced delirium, and the median hospital LOS was 6 [4-10] days. There was no difference in the primary outcomes of the two groups including rates of index admission mortality (PVNB: 5.2% vs. EA:6.3 %, p = 0.548) and delirium (PVNB: 12.4% vs. EA:12.9 %, p = 0.862). We also found no statistically significant difference between these groups in terms of 90-day respiratory complications (p = 1.000), 90-day readmission (p = 0.111), 90-day mortality (p = 0.718), and 90-day need for mechanical ventilation (p = 1.000). CONCLUSION: The use of PVNB in geriatric trauma patients with multiple rib fractures is associated with comparable in-hospital and post-discharge outcomes relative to EA. PVNB is relatively easy to perform and has a better side effect profile. The use of PVNB as part of rib fracture management protocols warrants further consideration. LEVEL OF EVIDENCE: III STUDY TYPE: Therapeutic/Care Management.

RESUMEN

INTRODUCTION: There is a lack of large-scale data on outcomes of cirrhotic patients undergoing trauma laparotomy. We aimed to compare outcomes of cirrhotic versus noncirrhotic trauma patients undergoing laparotomy. METHODS: We analyzed 2018 American College of Surgeons Trauma Quality Improvement Program. We included blunt trauma patients (≥18 y) who underwent a laparotomy. Patients who were transferred, dead on arrival, or had penetrating injuries were excluded. Patients were matched in a 1:2 ratio (cirrhotic and noncirrhotic). Outcomes included mortality, complications, failure to rescue, transfusion requirements, and hospital and intensive care unit (ICU) lengths of stay. Multivariable backward stepwise regression analysis was performed. RESULTS: Four hundred and seventy-one patients (cirrhotic, 157; noncirrhotic, 314) were matched. Mean age was 57 ± 15 y, 78% were male, and median injury severity score was 24. Cirrhotic patients had higher rates of mortality (60% versus 30%, P value <0.001), complications (49% versus 37%; P value = 0.01), failure to rescue (66% versus 36%, P value<0.001), and pRBC (units, median, 11 [7-18] versus 7 [4-11], P value <0.001) transfusion requirements. There were no significant differences in hospital and intensive care unit (ICU) lengths of stay (P value ≥0.05). On multivariate analysis, increasing age (adjusted odds ratio [aOR] 1.02, P value <0.001), Glasgow Coma Scale score ≤8 at presentation (aOR 3.3, P value <0.001), and total splenectomy (aOR 5.7, P value <0.001) were associated with higher odds of mortality. Platelet transfusion was associated with lower odds of mortality (aOR 0.84, P value = 0.044). CONCLUSIONS: On a national scale, mortality following trauma laparotomy is twice as high for cirrhotic patients compared to noncirrhotic patients with higher rates of major complications and failure to rescue. Our finding of a protective effect of platelet transfusion may be explained by the platelet dysfunction associated with cirrhosis. Liver cirrhosis among trauma patients warrants heightened surveillance.

RESUMEN

INTRODUCTION: We aimed to assess the effect of time to hepatic resection on the outcomes of patients with high-grade liver injuries who underwent damage control laparotomy (DCL). METHODS: This is a 4-year (2017-2020) analysis of the ACS-TQIP. Adult trauma patients with severe liver injuries (AAST-OIS grade â€‹≥ â€‹III) who underwent DCL and hepatic resection were included. We excluded patients with early mortality (<24 â€‹h). Patients were stratified into those who received hepatic resection within the initial operation (Early) and take-back operation (Delayed). RESULTS: Of 914 patients identified, 29% had a delayed hepatic resection. On multivariable regression analyses, although delayed resection was not associated with mortality (aOR:1.060,95%CI[0.57-1.97],p â€‹= â€‹0.854), it was associated with higher complications (aOR:1.842,95%CI[1.38-2.46],p â€‹< â€‹0.001), and longer hospital (ß: +0.129, 95%CI[0.04-0.22],p â€‹= â€‹0.005) and ICU (ß:+0.198,95%CI[0.14-0.25],p â€‹< â€‹0.001) LOS, compared to the early resection. CONCLUSION: Delayed hepatic resection was associated with higher adjusted odds of major complications and longer hospital and ICU LOS, however, no difference in mortality, compared to early resection.

RESUMEN

BACKGROUND: Our study compares the delayed outcomes of operative versus nonoperative management of pancreatic injuries. METHODS: We analyzed the 2017 Nationwide Readmissions Database on adult (≥18 years) trauma patients with pancreatic injuries. Patients who died on index admission were excluded. Patients were stratified into operative (OP) and non-operative (NOP) groups and compared for outcomes within 90 days of discharge. Multivariable regression analyses were performed. RESULTS: We identified 1553 patients (NOP â€‹= â€‹1092; OP â€‹= â€‹461). The Mean (SD) age was 39 (17.0) years, 31% of patients were female, and 77% had blunt injuries. Median ISS was 17 [9-25] and 74% had concomitant non-pancreatic intraabdominal injuries. On multivariable analysis, operative management was independently associated with increased odds of 90-day readmissions (aOR â€‹= â€‹1.47; p â€‹= â€‹0.03), intraabdominal abscesses (aOR â€‹= â€‹2.7; p â€‹< â€‹0.01), pancreatic pseudocyst (aOR â€‹= â€‹2.4; p â€‹= â€‹0.04), and need for percutaneous or endoscopic management (aOR â€‹= â€‹5.8; p â€‹< â€‹0.001). CONCLUSION: Operative management of pancreatic injuries is associated with higher rates of delayed complications compared to non-operative management. Surgically treated pancreatic trauma patients may need close surveillance even after discharge.

RESUMEN

INTRODUCTION: Multiple shock indices (SIs), including prehospital, emergency department (ED), and delta (ED SI - Prehospital SI) have been developed to predict outcomes among trauma patients. This study aims to compare the predictive abilities of these SIs for outcomes of polytrauma patients on a national level. METHODS: This was a retrospective analysis of the American College of Surgeons Trauma Quality Improvement Program (2017-2018). We included adult (≥18 y) trauma patients and excluded patients who were transferred, had missing vital signs, and those with severe head injuries (Head-Abbreviated Injury Scale>3). Outcome measures were 24-h and in-hospital mortality, 24-h packed red blood cells transfusions, and intensive care unit and hospital length of stay. Predictive performances of these SIs were evaluated by the Area Under the Receiver Operating Characteristics for the entire study cohort and across all injury severities. RESULTS: A total of 750,407 patients were identified. Meanstandard deviation age and lowest systolic blood pressure were 53 ± 21 y, and 81 ± 32 mmHg, respectively. Overall, 24-h and in-hospital mortality were 1.2% and 2.5%, respectively. On multivariable analysis, all three SIs were independently associated with higher rates of 24-h and in-hospital mortality, blood product requirements, intensive care unit and hospital length of stay (P < 0.001). ED SI was superior to prehospital and delta SIs (P < 0.001) for all outcomes. On subanalysis of patients with moderate injuries, severe injuries, and positive delta SI, the results remained the same. CONCLUSIONS: ED SI outperformed both prehospital and delta SIs across all injury severities. Trauma triage guidelines should prioritize ED SI in the risk stratification of trauma patients who may benefit from earlier and more intense trauma activations.
