Identifying potential utility of resuscitative endovascular balloon occlusion of the aorta: An autopsy study.

BACKGROUND: Resuscitative thoracotomy (RT) has been the standard therapy in patients with acute arrest due to hemorrhagic shock. However, with the development of resuscitative endovascular balloon occlusion of the aorta (REBOA), its role as a potential adjunct to a highly morbid intervention such as RT is being discussed. The aim of this study was to identify patients who most likely would have potentially benefited from REBOA use based on autopsy findings. METHODS: We performed a 4-year retrospective review of all RTs performed at our Level I trauma center. Patients with in-hospital mortality and who underwent subsequent autopsies were included. Patients were divided into blunt and penetrating trauma with and without thoracic injuries. Autopsy reports were reviewed to identify vascular and solid organ injuries. Outcome measure was potential benefit with REBOA. Potential benefit with REBOA was defined based on the ability to safely deploy REBOA. In patients without cardiac, aortic, and major pulmonary vasculature injuries, REBOA was considered potentially beneficial. In all other patients, it was considered as nonbeneficial. RESULTS: A total of 98 patients underwent an RT, of whom 87 had subsequent autopsies and were reviewed. The mean age was 35.25 (SD, 17.85) years, mean admission systolic blood pressure was 51.38 (SD, 70.11) mm Hg, median Injury Severity Score was 29 (interquartile range [IQR], 25-42), and 44 had penetrating injury. Resuscitative endovascular balloon occlusion of the aorta would have been potentially beneficial in 51.2% of patients (22 of 43 patients) with blunt mechanism of trauma, whereas REBOA would have been potentially beneficial in 38.6% of patients (17 of 44 patients) with penetrating mechanism of trauma. A subgroup analysis showed that REBOA use would have been potentially beneficial in 50.0% of blunt thoracic and 33.3% of penetrating thoracic trauma patients. CONCLUSIONS: There are a great enthusiasm and premature efforts to introduce REBOA as an alternative to RT. While there exists a great potential for benefit with REBOA use in the management of noncompressible torso hemorrhage, the current indications for REBOA need to be defined better. Patients with penetrating chest trauma in extremis should be considered an absolute contraindication for REBOA use. The majority of patients with blunt trauma in extremis may potentially benefit from REBOA. However, better criteria will help increase these patients who may potentially benefit from REBOA placement.

The impact of patient protection and Affordable Care Act on trauma care: A step in the right direction.

INTRODUCTION: The Patient Protection and Affordable Care Act (ACA) was implemented to guarantee financial coverage for health care for all Americans. The implementation of ACA is likely to influence the insurance status of Americans and reimbursement rates of trauma centers. The aim of this study was to assess the impact of ACA on the patient insurance status, hospital reimbursements, and clinical outcomes at a Level I trauma center. We hypothesized that there would be a significant decrease in the proportion of uninsured trauma patients visiting our Level I trauma center following the ACA, and this is associated with improved reimbursement. METHODS: We performed a retrospective analysis of the trauma registry and financial database at our Level I trauma center for a 27-month (July 2012 to September 2014) period by quarters. Our outcome measures were change in insurance status, hospital reimbursement rates (total payments/expected payments), and clinical outcomes before and after ACA (March 31, 2014). Trend analysis was performed to assess trends in outcomes over each quarter (3 months). RESULTS: A total of 9,892 patients were included in the study. The overall uninsured rate during the study period was 20.3%. Post-ACA period was associated with significantly lower uninsured rate (p < 0.001). During the same time, there was as a significant increase in the Medicaid patients (p = 0.009). This was associated with significantly improved hospital reimbursements (p < 0.001).On assessing clinical outcomes, there was no change in hospitalization (p = 0.07), operating room procedures (p = 0.99), mortality (p = 0.88), or complications (p = 0.20). Post-ACA period was also not associated with any change in the hospital (p = 0.28) or length of stay at intensive care unit (p = 0.66). CONCLUSION: The implementation of ACA has led to a decrease in the number of uninsured trauma patients. There was a significant increase in Medicaid trauma patients. This was associated with an increase in hospital reimbursements that substantially improved the financial revenues. Despite the controversies, implementation of ACA has the potential to substantially improve the financial outcomes of trauma centers through Medicaid expansion.

The elimination of anastomosis in open trauma vascular reconstruction: A novel technique using an animal model.

BACKGROUND: The standard approach to vascular trauma involves arterial exposure and reconstruction using either a vein or polytetrafluoroethylene graft. We have developed a novel technique to repairing arterial injuries by deploying commercially available vascular stents through an open approach, thus eliminating the need for suture anastomosis. The objective of this study was to evaluate the feasibility, stent deployment time (SDT), and stent patency of this technique in a ewe vascular injury model. METHODS: After proximal and distal control, a 2-cm superficial femoral arterial segment was resected in 8 Dorper ewes to simulate an arterial injury. Two stay sutures were placed in the 3- and 9-o'clock positions of the transected arterial ends to prevent further retraction. Ten milliliters of 10-IU/mL heparinized saline was flushed proximally and distally. An arteriotomy was then created 2.5 cm from the transected distal end through which we deployed Gore Viabahn stents with a 20% oversize and at least 1-cm overlap with the native vessel on either end. The arteriotomy was then closed with 3 (1) interrupted 6-0 Prolene sutures. The ewes were fed acetylsalicylic acid 325 mg daily. Duplex was performed at 2 months postoperatively to evaluate stent patency. SDT was defined as time from stay suture placement to arteriotomy closure. RESULTS: The 8 ewes weighed a mean (SD) of 34.4 (4.3) kg. The mean (SD) superficial femoral arterial was 4.3 (0.6) mm. Six 5 mm × 5 cm and two 6 mm × 5 cm Gore Viabahn stents were deployed. The mean (SD) SDT was 34 (19) minutes, with a trend toward less time with increasing experience (SDTmax, 60 minutes; SDTmin, 10 minutes). Duplex performed at 2 months postoperatively showed stent patency in five of eight stents. There was an association between increasing SDT and stent thrombosis. CONCLUSION: Open deployment of commercially available vascular stents to treat vascular injuries is a conceptually sound and technically feasible alternative to standard open repair. Larger studies are needed to refine this technique and minimize stent complications, which are likely technical in nature.

Increasing organ donation after cardiac death in trauma patients.

BACKGROUND: Organ donation after cardiac death (DCD) is not optimal but still remains a valuable source of organ donation in trauma donors. The aim of this study was to assess national trends in DCD from trauma patients. METHODS: A 12-year (2002 to 2013) retrospective analysis of the United Network for Organ Sharing database was performed. Outcome measures were the following: proportion of DCD donors over the years and number and type of solid organs donated. RESULTS: DCD resulted in procurement of 16,248 solid organs from 8,724 donors. The number of organs donated per donor remained unchanged over the study period (P = .1). DCD increased significantly from 3.1% in 2002 to 14.6% in 2013 (P = .001). There was a significant increase in the proportion of kidney (2002: 3.4% vs 2013: 16.3%, P = .001) and liver (2002: 1.6% vs 2013: 5%, P = .041) donation among DCD donors over the study period. CONCLUSIONS: DCD from trauma donors provides a significant source of solid organs. The proportion of DCD donors increased significantly over the last 12 years.

Predictors of failure in the Advanced Trauma Life Support course.

BACKGROUND: Over 1 million healthcare providers have participated in the Advanced Trauma Life Support course. No studies have evaluated factors that predict course performance. This study aims to identify these predictors. METHODS: All participants taking the course at 2 centers over a 4-year period were identified. Demographics, background, and performance data were extracted. Participants who failed were compared with those who did not. Stepwise logistic regression analysis was used to identify independent risk factors for failure. RESULTS: Seven hundred forty-four healthcare providers participated in the course; 89.5% passed and 10.5% failed. Failure rates were lowest (.0%) among Trauma/Surgical Critical Care (SCC) providers and highest among pediatric providers (28.6%). Stepwise logistic regression identified age greater than 55, English as a second language, pretest score less than 75, and non-Trauma/SCC and non-Emergency Medicine background as predictors of failure. CONCLUSIONS: A failure rate of 10.5% was demonstrated among the course participants. Age greater than 55, English as second language, pretest score less than 75, and non-Trauma/SCC and non-Emergency Medicine backgrounds were associated with failure. These subgroups may benefit from performance improvement measures.

Adverse effects of admission blood alcohol on long-term cognitive function in patients with traumatic brain injury.

BACKGROUND: Alcohol is known to be protective in patients with traumatic brain injury (TBI); however, its impact on the long-term cognitive function is unknown. We hypothesize that intoxication at the time of injury is associated with adverse long-term cognitive function in patients sustaining TBI. METHODS: We performed a 2-year retrospective study of all trauma patients with isolated TBI presenting to our Level I trauma center and discharged to a single rehabilitation facility. Patients with moderate-to-severe TBI (head Abbreviated Injury Scale [AIS] score ≥ 3), measured admission blood alcohol concentration, and measured cognitive function on hospital discharge and rehabilitation center discharge were included. Cognitive function was assessed using Functional Independence Measure (FIM) scores. Delta cognitive FIM was defined as the difference between rehabilitation center discharge and hospital discharge cognitive FIM scores. Multivariate linear regression was performed. RESULTS: A total of 64 patients were included. Mean (SD) age was 51.8 (23) years, median head AIS score was 3 (IQR, 3-5), and median Glasgow Coma Scale (GCS) score was 11 (IQR, 3-15). Mean (SD) cognitive FIM score on hospital discharge was 17 (6), and mean (SD) cognitive improvement was 8.6 (4.7). Sixty percent (n = 39) were under the influence of alcohol on admission, and the mean (SD) admission blood alcohol concentration was 132 (102).On multivariate linear regression analysis, admission blood alcohol concentration (ß = -0.4; 95% confidence interval, -6.7 to -0.8; p = 0.01) and age (ß = -0.13; 95% confidence interval, -0.2 to -0.04; p = 0.04) were negatively associated with improvement in long-term cognitive function. CONCLUSION: Alcohol intoxication at the time of injury is associated with lower improvement in long-term cognitive function. Older intoxicated patients are likely to have a lower cognitive improvement. LEVEL OF EVIDENCE: Prognostic and epidemiologic study, level III.

Overuse of helicopter transport in the minimally injured: A health care system problem that should be corrected.

BACKGROUND: Mortality benefit has been demonstrated for trauma patients transported via helicopter but at great cost. This study identified patients who did not benefit from helicopter transport to our facility and demonstrates potential cost savings when transported instead by ground. METHODS: We performed a 6-year (2007-2013) retrospective analysis of all trauma patients presenting to our center. Patients with a known mode of transfer were included in the study. Patients with missing data and those who were dead on arrival were excluded from the study. Patients were then dichotomized into helicopter transfer and ground transfer groups. A subanalysis was performed between minimally injured patients (ISS < 5) in both the groups after propensity score matching for demographics, injury severity parameters, and admission vital parameters. Groups were then compared for hospital and emergency department length of stay, early discharge, and mortality. RESULTS: Of 5,202 transferred patients, 18.9% (981) were transferred via helicopter and 76.7% (3,992) were transferred via ground transport. Helicopter-transferred patients had longer hospital (p = 0.001) and intensive care unit (p = 0.001) stays. There was no difference in mortality between the groups (p = 0.6).On subanalysis of minimally injured patients there was no difference in hospital length of stay (p = 0.1) and early discharge (p = 0.6) between the helicopter transfer and ground transfer group. Average helicopter transfer cost at our center was $18,000, totaling $4,860,000 for 270 minimally injured helicopter-transferred patients. CONCLUSION: Nearly one third of patients transported by helicopter were minimally injured. Policies to identify patients who do not benefit from helicopter transport should be developed. Significant reduction in transport cost can be made by judicious selection of patients. Education to physicians calling for transport and identification of alternate means of transportation would be both safe and financially beneficial to our system.

Mild traumatic brain injury defined by Glasgow Coma Scale: Is it really mild?

INTRODUCTION: Conventionally, a Glasgow Coma Scale (GCS) score of 13-15 defines mild traumatic brain injury (mTBI). The aim of this study was to identify the factors that predict progression on repeat head computed tomography (RHCT) and neurosurgical intervention (NSI) in patients categorized as mild TBI with intracranial injury (intracranial haemorrhage and/or skull fracture). METHODS: This study performed a retrospective chart review of all patients with traumatic brain injury who presented to a level 1 trauma centre. Patients with blunt TBI, an intracranial injury and admission GCS of 13-15 without anti-platelet and anti-coagulation therapy were included. The outcome measures were: progression on RHCT and need for neurosurgical intervention (craniotomy and/or craniectomy). RESULTS: A total of 1800 patients were reviewed, of which 876 patients were included. One hundred and fifteen (13.1%) patients had progression on RHCT scan. Progression on RHCT was 8-times more likely in patients with subdural haemorrhage ≥10 mm, 5-times more likely with epidural haemorrhage ≥10 mm and 3-times more likely with base deficit ≥4. Forty-seven patients underwent a neurosurgical intervention. Patients with displaced skull fracture were 10-times more likely and patients with base deficit >4 were 21-times more likely to have a neurosurgical intervention. CONCLUSION: In patients with intracranial injury, a mild GCS score (GCS 13-15) in patients with an intracranial injury does not preclude progression on repeat head CT and the need for a neurosurgical intervention. Base deficit greater than four and displaced skull fracture are the greatest predictors for neurosurgical intervention in patients with mild TBI and an intracranial injury.

An acute care surgery dilemma: emergent laparoscopic cholecystectomy in patients on aspirin therapy.

BACKGROUND: The current literature regarding hemorrhagic complications in patients on long-term antiplatelet therapy undergoing emergent laparoscopic cholecystectomy is limited. The aim of our study was to describe hemorrhagic complications in patients on prehospital aspirin (ASP) therapy undergoing emergent cholecystectomy. METHODS: We performed a 1-year retrospective analysis of our prospectively maintained acute care surgery database. The 2 groups (ASP group vs No ASP group) were matched in a 1:1 ratio for age, sex, previous abdominal surgeries, and comorbidities. Primary outcome measures were intraoperative hemorrhage, postoperative anemia, need for blood transfusion, and conversion to open cholecystectomy. Intraoperative hemorrhage was defined as intraoperative blood loss of ≥ 100 mL; postoperative anemia was defined by ≥ 2 g/dL drop in hemoglobin. RESULTS: A total of 112 (ASP: 56, no ASP: 56) patients were included in the analysis. The mean age was 65.9 ± 10 years, and 50% were male. There was no difference in age (P = .9), sex (P = .9), and comorbidities (P = .7) between the 2 groups. There was no difference in intraoperative blood loss >100 mL (P = .5), postoperative anemia (P = .8), blood transfusion requirement (P = .9), and conversion to open surgery (P = .7) between patients on American Society of Anesthesiologists therapy and patients not on American Society of Anesthesiologists therapy. CONCLUSIONS: Emergent laparoscopic cholecystectomy is a safe procedure in patients on long-term ASP. Prehospital use of ASP as an independent factor should not be used to delay emergent cholecystectomy.

Clinical outcomes in patients on preinjury ibuprofen with traumatic brain injury.

BACKGROUND: The aim of our study was to evaluate the clinical outcomes in patients on preinjury Ibuprofen with traumatic brain injury. METHODS: We performed a 2-year analysis of all patients on prehospital Ibuprofen with traumatic brain injury and intracranial hemorrhage. Patients on preinjury Ibuprofen were matched using propensity score matching to patients not on Ibuprofen in a 1:2 ratio for age, Glasgow Coma Scale, head-abbreviated injury scale, injury severity score, International Normalized Ratio, and neurologic examination. Outcome measures were progression on repeat head computed tomography (RHCT) and neurosurgical intervention. RESULTS: A total of 195 matched (Ibuprofen 65, no-Ibuprofen 130) patients were included. There was no difference in the progression on RHCT (Ibuprofen 18% vs. no-Ibuprofen 24%; P = .50). The neurosurgical intervention rate was 18.9% (n = 37). There was no difference for need for neurosurgical intervention (26% vs. 16%; P = .10) between the 2 groups. CONCLUSIONS: In a matched cohort of trauma patients, preinjury Ibuprofen use was not associated with progression of initial intracranial hemorrhage and the need for neurosurgical intervention. Preinjury use of Ibuprofen as an independent variable should not warrant the need for a routine RHCT scan.

Early thromboembolic prophylaxis in patients with blunt solid abdominal organ injuries undergoing nonoperative management: is it safe?

BACKGROUND: The aim of this study was to compare the safety of early (≤48 hours), intermediate (48 to 72 hours), and late (≥72 hours) venous thromboembolism prophylaxis in patients with blunt abdominal solid organ injury managed nonoperatively. METHODS: We performed a 6-year (2006 to 2011) retrospective review of all trauma patients with blunt abdominal solid organ injuries. Patients were matched using propensity score matching in a 2:1:1 (early:intermediate:late) for age, gender, systolic blood pressure, Glasgow Coma Scale, Injury Severity Score, and type and grade of organs injured. Our primary outcome measures were: hemorrhage complications and need for intervention (operative intervention and/or angioembolization). RESULTS: A total of 116 patients (58 early, 29 intermediate, and 29 late) were included. There were no differences in age (P = .5), Injury Severity Score (P = .6), type (P = .1), and grade of injury of the organ (P = .6) between the 3 groups. There were 67 liver (43.2%), 63 spleen (40.6%), 49 kidney (31.6%), and 24 multiple solid organ (15.4%) injuries. There was no difference in operative intervention (P = .8) and postprophylaxis blood transfusion (P = .3) between the 3 groups. CONCLUSIONS: Early enoxaparin-based anticoagulation may be a safe option in trauma patients with blunt solid organ injury. This study showed no significant correlation between early anticoagulation and development of bleeding complications.

Prospective validation of the brain injury guidelines: managing traumatic brain injury without neurosurgical consultation.

BACKGROUND: To optimize neurosurgical resources, guidelines were developed at our institution, allowing the acute care surgeons to independently manage traumatic intracranial hemorrhage less than or equal to 4 mm. The aim of our study was to evaluate our established Brain Injury Guidelines (BIG 1 category) for managing patients with traumatic brain injury (TBI) without neurosurgical consultation. METHODS: We formulated the BIG based on a 4-year retrospective chart review of all TBI patients presenting at our Level 1 trauma center. We then prospectively implemented our BIG 1 category to identify TBI patients that were to be managed without neurosurgical consultation (No-NC). Propensity scoring matched patients with No-NC to a similar cohort of patients managed with NC before the implementation of our BIG in a 1:1 ratio for demographics, severity of injury, and type and size of intracranial hemorrhage. Primary outcome measure was need for neurosurgical intervention and 30-day readmission rates. RESULTS: A total of 254 TBI patients (127 of NC and 127 of No-NC patients) were included in the analysis. The mean (SD) age was 40.8 (22.7) years, 63.4% (n = 161) were male, median Glasgow Coma Scale (GCS) score was 15 (range, 13-15), and median head Abbreviated Injury Scale (AIS) score was 2 (range, 2-3). There was no neurosurgical intervention or 30-day readmission in both the groups. In the No-NC group, 3.9% of the patients had postdischarge emergency department visits compared with 4.7% of the NC group (p = 0.5). All patients were discharged home from the emergency department. CONCLUSION: We validated our BIG and demonstrated that acute care surgeons can effectively care for minimally injured TBI patients with good outcomes. A national multi-institutional prospective evaluation is warranted. LEVEL OF EVIDENCE: Therapeutic/care management, level IV.

Management of acute mild gallstone pancreatitis under acute care surgery: should patients be admitted to the surgery or medicine service?

BACKGROUND: We hypothesized that patients with acute mild gallstone pancreatitis (GSP) admitted to surgery (SUR; vs medicine [MED]) had a shorter time to surgery, shorter hospital length of stay (HLOS), and lower costs. METHODS: We performed chart reviews of patients who underwent a cholecystectomy for acute mild GSP from October 1, 2009 to May 31, 2013. We excluded patients with moderate to severe and non-gallstone pancreatitis. We compared outcomes for time to surgery, HLOS, costs, and complications between the 2 groups. RESULTS: Fifty acute mild GSP patients were admitted to MED and 52 to SUR. MED patients were older and had more comorbidity. SUR patients had a shorter time to surgery (44 vs 80 hours; P < .001), a shorter HLOS (3 vs 5 days; P < .001), and lower hospital costs ($11,492 ± 6,480 vs $16,183 ± 12,145; P = .03). In our subgroup analysis on patients with an American Society of Anesthesiologists score between 1 and 2, the subgroups were well matched; all outcomes still favored SUR patients. CONCLUSIONS: Admitting acute mild GSP patients directly to SUR shortened the time to surgery, shortened HLOS, and lowered hospital costs.

Hypothermia in organ donation: a friend or foe?

BACKGROUND: Hypothermia is a known predictor of mortality in trauma patients; however, its impact on organ procurement has not been defined. The aim of this study was to assess the effect of hypothermia on organ procurement. We hypothesized that admission hypothermia impedes successful organ procurement. METHODS: We performed a 5-year retrospective analysis of all trauma patients approached for organ donation. Hypothermia was defined as a core body temperature 36°C/97°F or less. The two groups (hypothermic [HT] vs. nonhypothermic [non-HT]) were matched in a 1:1 ratio using propensity score matching for age, sex, admission Glasgow Coma Scale (GCS) score, systolic blood pressure, international normalized ratio, and Injury Severity Score (ISS). Primary outcome measures were eligibility for organ donation and solid organ procurement. Secondary outcome measures were blood product and vasopressor requirements. RESULTS: This study was composed of 537 brain-dead patients, of whom 416 (HT, 208; non-HT, 208) were included in the analysis. The mean (SD) age was 40.5 (23.7) years, 75% were male, mean (SD) temperature was 36.6°C (1.7°C), and mean (SD) systolic blood pressure was 75.35 (68.7) mm Hg. Patients who were hypothermic on presentation were less likely to be eligible for organ donation (44.7% vs. 96%, p ≤ 0.001), and they donated fewer organs per donor (p = 0.04). HT patients required more units of fresh frozen plasma (p = 0.04) and greater mean dose of dopamine (p = 0.03) and vasopressin (p = 0.03) compared with the non-HT patients. CONCLUSION: Admission hypothermia is associated with decreased organ donation in potential organ donors independent of admission coagulopathy, hypotension, and injury severity. Early correction of hypothermia may improve organ donation in trauma patients. LEVEL OF EVIDENCE: Epidemiologic/prognostic study, level III.

Unveiling posttraumatic stress disorder in trauma surgeons: a national survey.

BACKGROUND: The significance of posttraumatic stress disorder (PTSD) in trauma patients is well recognized. The impact trauma surgeons endure in managing critical trauma cases is unknown. The aim of our study was to assess the incidence of PTSD among trauma surgeons and identify risk factors associated with the development of PTSD. METHODS: We surveyed all members of the American Association for Surgery of Trauma and the Eastern Association for Surgery of Trauma using an established PTSD screening test (PTSD Checklist Civilian [PCL-C]). A PCL-C score of 35 or higher (sensitivity > 85%) was used as the cutoff for the development of PTSD symptoms and a PCL-C score of 44 or higher for the diagnosis of PTSD. Multivariate logistic regression was performed. RESULTS: There were 453 respondents with a 41% response rate. PTSD symptoms were present in 40% (n = 181) of the trauma surgeons, and 15% (n = 68) of the trauma surgeons met the diagnostic criteria for PTSD. Male trauma surgeons (odds ratio [OR], 2; 95% confidence interval [CI], 1.2-3.1) operating more than 15 cases per month (OR, 3; 95% CI, 1.2-8), having more than seven call duties per month (OR, 2.6; 95% CI, 1.2-6), and with less than 4 hours of relaxation per day (OR, 7; 95% CI, 1.4-35) were more likely to develop symptoms of PTSD. Diagnosis of PTSD was common in trauma surgeons managing more than 5 critical cases per call duty (OR, 7; 95% CI, 1.1-8). Salary, years of clinical practice, and previous military experience were predictive for neither the development of PTSD symptoms nor the diagnosis of PTSD. CONCLUSION: Both symptoms and the diagnosis of PTSD are common among trauma surgeons. Defining the factors that predispose trauma surgeons to PTSD may be of benefit to the patients and the profession. The data from this survey will be useful to major national trauma surgery associations for developing targeted interventions. LEVEL OF EVIDENCE: Epidemiologic study, level III.

Validating trauma-specific frailty index for geriatric trauma patients: a prospective analysis.

BACKGROUND: The Frailty Index has been shown to predict discharge disposition in geriatric patients. The aim of this study was to validate the modified 15-variable Trauma-Specific Frailty Index (TSFI) to predict discharge disposition in geriatric trauma patients. We hypothesized that TSFI can predict discharge disposition in geriatric trauma patients. STUDY DESIGN: We performed a 2-year (2011-2013) prospective analysis of all geriatric trauma patients presenting to our Level I trauma center. Patient discharge disposition was dichotomized into unfavorable (discharge to skilled nursing facility or death) and favorable (discharge to home or rehabilitation center) discharge disposition. Patients were evaluated using the developed 15-variable TSFI. Multivariate logistic regression was performed to identify factors that predict unfavorable discharge disposition. RESULTS: A total of 200 patients were enrolled for validation of TSFI. Mean age was 77 ± 12.1 years, median Injury Severity Score was 15 (interquartile range [IQR] 9 to 20), median Glasgow Coma Scale score was 14 (IQR 13 to 15), and median Frailty Index score was 0.20 (IQR 0.17 to 0.28); 29.5% (n = 59) patients had unfavorable discharge. After adjusting for age, sex, Injury Severity Score, Head Abbreviated Injury Scale, and vitals on admission, Frailty Index (odds ratio = 1.5; 95% CI, 1.1-2.5) was the only significant predictor for unfavorable discharge disposition. Age (odds ratio = 1.2; 95% CI, 0.9-3.1; p = 0.2) was not predictive of unfavorable discharge disposition. CONCLUSIONS: The 15-variable TSFI is an independent predictor of unfavorable discharge disposition in geriatric trauma patients. The Trauma-Specific Frailty Index is an effective tool that can aid clinicians in planning discharge disposition of geriatric trauma patients.

Superiority of frailty over age in predicting outcomes among geriatric trauma patients: a prospective analysis.

IMPORTANCE: The Frailty Index (FI) is a known predictor of adverse outcomes in geriatric patients. The usefulness of the FI as an outcome measure in geriatric trauma patients is unknown. OBJECTIVE: To assess the usefulness of the FI as an effective assessment tool in predicting adverse outcomes in geriatric trauma patients. DESIGN, SETTING, AND PARTICIPANTS: A 2-year (June 2011 to February 2013) prospective cohort study at a level I trauma center at the University of Arizona. We prospectively measured frailty in all geriatric trauma patients. Geriatric patients were defined as those 65 years or older. The FI was calculated using 50 preadmission frailty variables. Frailty in patients was defined by an FI of 0.25 or higher. MAIN OUTCOMES AND MEASURES: The primary outcome measure was in-hospital complications. The secondary outcome measure was adverse discharge disposition. In-hospital complications were defined as cardiac, pulmonary, infectious, hematologic, renal, and reoperation. Adverse discharge disposition was defined as discharge to a skilled nursing facility or in-hospital mortality. Multivariate logistic regression was used to assess the relationship between the FI and outcomes. RESULTS: In total, 250 patients were enrolled, with a mean (SD) age of 77.9 (8.1) years, median Injury Severity Score of 15 (range, 9-18), median Glasgow Coma Scale score of 15 (range, 12-15), and mean (SD) FI of 0.21 (0.10). Forty-four percent (n = 110) of patients had frailty. Patients with frailty were more likely to have in-hospital complications (odds ratio, 2.5; 95% CI, 1.5-6.0; P = .001) and adverse discharge disposition (odds ratio, 1.6; 95% CI, 1.1-2.4; P = .001). The mortality rate was 2.0% (n = 5), and all patients who died had frailty. CONCLUSIONS AND RELEVANCE: The FI is an independent predictor of in-hospital complications and adverse discharge disposition in geriatric trauma patients. This index should be used as a clinical tool for risk stratification in this patient group.

Prothrombin complex concentrate use in coagulopathy of lethal brain injuries increases organ donation.

Coagulopathy is a defined barrier for organ donation in patients with lethal traumatic brain injuries. The purpose of this study was to document our experience with the use of prothrombin complex concentrate (PCC) to facilitate organ donation in patients with lethal traumatic brain injuries. We performed a 4-year retrospective analysis of all patients with devastating gunshot wounds to the brain. The data were analyzed for demographics, change in international normalized ratio (INR), and subsequent organ donation. The primary end point was organ donation. Eighty-eight patients with lethal traumatic brain injury were identified from the trauma registry of whom 13 were coagulopathic at the time of admission (mean INR 2.2 ± 0.8). Of these 13 patients, 10 patients received PCC in an effort to reverse their coagulopathy. Mean INR before PCC administration was 2.01 ± 0.7 and 1.1 ± 0.7 after administration (P < 0.006). Correction of coagulopathy was attained in 70 per cent (seven of 10) patients. Of these seven patients, consent for donation was obtained in six patients and resulted in 19 solid organs being procured. The cost of PCC per patient was $1022 ± 544. PCC effectively reveres coagulopathy associated with lethal traumatic brain injury and enabled patients to proceed to organ donation. Although various methodologies exist for the treatment of coagulopathy to facilitate organ donation, PCC provides a rapid and cost-effective therapy for reversal of coagulopathy in patients with lethal traumatic brain injuries.

Effect of alcohol in traumatic brain injury: is it really protective?

BACKGROUND: Studies have proposed a neuroprotective role for alcohol (ETOH) in traumatic brain injury (TBI). We hypothesized that ETOH intoxication is associated with mortality in patients with severe TBI. METHODS: Version 7.2 of the National Trauma Data Bank (2007-2010) was queried for all patients with isolated blunt severe TBI (Head Abbreviated Injury Score ≥4) and blood ETOH levels recorded on admission. Primary outcome measure was mortality. Multivariate logistic regression analysis was performed to assess factors predicting mortality and in-hospital complications. RESULTS: A total of 23,983 patients with severe TBI were evaluated of which 22.8% (n = 5461) patients tested positive for ETOH intoxication. ETOH-positive patients were more likely to have in-hospital complications (P = 0.001) and have a higher mortality rate (P = 0.01). ETOH intoxication was an independent predictor for mortality (odds ratio: 1.2, 95% confidence interval: 1.1-2.1, P = 0.01) and development of in-hospital complications (odds ratio: 1.3, 95% confidence interval: 1.1-2.8, P = 0.009) in patients with isolated severe TBI. CONCLUSIONS: ETOH intoxication is an independent predictor for mortality in patients with severe TBI patients and is associated with higher complication rates. Our results from the National Trauma Data Standards differ from those previously reported. The proposed neuroprotective role of ETOH needs further clarification.
