Background Numerous factors contribute to advanced disease or increased complications in patients with acute appendicitis (AA). This study aimed to identify risk factors associated with AA perforation, including the effect of system time (ST) delay, after controlling for patient time (PT) delay. In this study, PT was controlled (to less than or equal to 24 h) to better understand the effect of ST delay on AA perforation. Methods Medical records of patients who underwent surgery for AA at a tertiary referral hospital from October 2009 through September 2013 were reviewed. Data collected included demographics, body mass index, presence of fecalith, PT (i.e., duration of time from symptom onset to arrival in emergency department), and ST (i.e., duration of time from arrival in emergency department to operating room). AA was classified as simple (acute, nonperforated) versus advanced (gangrenous, perforated). Results Seven hundred forty-seven patients underwent surgery for AA. After excluding patients with PT > 24 h, 445 patients fit the study criteria, of which 358 patients with simple AA and 87 patients with advanced disease. Advanced appendicitis patients were older and had higher body mass index, longer PT, higher WBC, and higher incidence of fecaliths. Both groups had similar ST. Risk factors for advanced appendicitis after multiple regression analysis are age >50 y old, WBC >15,000, the presence of fecaliths, and PT delay >12 h. Conclusions Once PT delay was limited to ≤24 h, the ST delay of >12 h did not adversely affect the incidence of advanced AA. Age >50 y, WBC >15,000, PT delay >12 h, and the presence of fecaliths were identified as risk factors associated with advanced AA.

The effectiveness of 14-French (14F) pigtail catheters (PCs) compared to 32-40F chest tubes (CTs) in patients with traumatic hemothorax (HTX) and hemopneumothorax (HPTX) is becoming more well known but still lacking. The aim of our study was to analyze our cumulative experience and outcomes with PCs in patients with traumatic HTX/HPTX. We hypothesized that PCs would be as effective as CTs. Using our PC database, we analyzed all trauma patients who required chest drainage for HTX/HPTX from 2008 to 2014. Primary outcomes of interest, comparing PCs to CTs, included initial drainage output in milliliters (mL), tube insertion-related complications, and failure rate. For our statistical analysis, we used the unpaired Student’s t test, Chi-square test, and Wilcoxon rank-sum test. We defined statistical significance as P

Background Nonoperative management of hemodynamically stable children with Solid Organ Injury (SOI) has become standard of care. The aim of this study is to identify differences in management of children with SOI treated at Adult Trauma Centers (ATC) versus Pediatric Trauma Centers (PTC). We hypothesized that patients treated at ATC would undergo more procedures than PTC. Methods Patients younger than 18 years old with isolated SOI (spleen, liver, kidney) who were treated at level I-II ATC or PTC were identified from the 2011–2012 National Trauma Data Bank. The primary outcome measure was the incidence of operative management. Data was analyzed using multivariate logistic regression analysis. Procedures were defined as surgery or transarterial embolization (TAE). Results 6799 children with SOI (spleen: 2375, liver: 2867, kidney: 1557) were included. Spleen surgery was performed more frequently at ATC than PTC {101 (7.7%) vs. 52 (4.9%); P=0.007}. After adjusting for potential confounders (grade of injury, age, gender and injury severity score), admission at ATC was associated with higher odds of splenic surgery (OR: 1.5, 95% CI: 1.02–2.25; p=0.03). 11 and 8 children underwent kidney and liver operations respectively. TAE was performed in 17 patients with splenic, 34 with liver and 14 with kidney trauma. There was no practice variation between ATC and PTC regarding kidney and liver operations or TAE incidence. Conclusions Operative management for SOI was more often performed at ATC. The presence of significant disparity in the management of children with splenic injuries justifies efforts to use these surgeries as a reported national quality indicator for trauma programs.

Background Multiple prior studies have suggested an association between survival and beta-blocker administration in patients with severe traumatic brain injury (TBI). However, it is unknown whether this benefit of beta-blockers is dependent on heart rate control. The aim of this study was to assess whether rate control affects survival in patients receiving metoprolol with severe TBI. Our hypothesis was that improved survival from beta-blockade would be associated with a reduction in heart rate. Methods We performed a 7-y retrospective analysis of all blunt TBI patients at a level-1 trauma center. Patients aged >16 y with head abbreviated injury scale 4 or 5, admitted to the intensive care unit (ICU) from the operating room or emergency room (ER), were included. Patients were stratified into two groups: metoprolol and no beta-blockers. Using propensity score matching, we matched the patients in two groups in a 1:1 ratio controlling for age, gender, race, admission vital signs, Glasgow coma scale, injury severity score, mean heart rate monitored during ICU admission, and standard deviation of heart rate during the ICU admission. Our primary outcome measure was mortality. Results A total of 914 patients met our inclusion criteria, of whom 189 received beta-blockers. A propensity-matched cohort of 356 patients (178: metoprolol and 178: no beta-blockers) was created. Patients receiving metoprolol had higher survival than those patients who did not receive beta-blockers (78% versus 68%; P = 0.04); however, there was no difference in the mean heart rate (89.9 ± 13.9 versus 89.9 ± 15; P = 0.99). Nor was there a difference in the mean of standard deviation of the heart rates (14.7 ± 6.3 versus 14.4 ± 6.5; P = 0.65) between the two groups. In Kaplan–Meier survival analysis, patients who received metoprolol had a survival advantage (P = 0.011) compared with patients who did not receive any beta-blockers. Conclusions Our study shows an association with improved survival in patients with severe TBI receiving metoprolol, and this effect appears to be independent of any reduction in heart rate. We suggest that beta-blockers should be administered to all severe TBI patients irregardless of any perceived beta-blockade effect on heart rate.

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.

Background Percutaneous endoscopic gastrostomy (PEG) complications are often under-reported in the literature, especially regarding the incidence of tube dislodgement (TD). TD can cause significant morbidity depending on its timing. We compared outcomes between “push” and “pull” PEGs. We hypothesized that push PEGs, because of its T-fasteners and balloon tip, would have a lower incidence of TD and complications compared with pull PEGs. Methods We performed a chart review of our prospectively maintained acute care surgery database for patients who underwent PEG tube placement from July 1, 2009 through June 30, 2013. Data regarding age, gender, body mass index, indications (trauma versus nontrauma), and complications (including TD) were extracted. Procedure-related complications were classified as either major if patients required an operative intervention or minor if they did not. We compared outcomes between pull PEG and push PEG. Multiple regression analysis was performed to identify risk factors associated with major complications. Results During the 4-y study period, 264 patients underwent pull PEGs and 59 underwent push PEGs. Age, gender, body mass index, and indications were similar between the two groups. The overall complications (major and minor) were similar (20% pull versus 22% push, P = 0.61). The incidence of TD was also similar (12% pull versus 9% push, P = 0.49). However, TD associated with major complications was higher in pull PEGs but was not statistically significant (6% pull versus 2% push, P = 0.21). Multiple regression analysis showed that dislodged pull PEG was associated with major complications (odds ratio 29.5; 95% confidence interval, 11.3-76.9; P Conclusions The incidence of pull PEG TD associated with major complications is under-recognized. Specific measures should be undertaken to help prevent pull PEG TD. Level of evidence IV, therapeutic.

Hypopituitarism after hypovolemic shock is well established in certain patient cohorts. However; the effects of hemorrhagic shock on pituitary function in trauma patients remains unknown. The aim of this study was to assess pituitary hormone variations in trauma patients with hemorrhagic shock.Patients with acute traumatic hemorrhagic shock presenting to our level 1 trauma center were prospectively enrolled. Hemorrhagic shock was defined as systolic blood pressure (SBP) ≤ 90 mmHg on arrival or within 10 minutes of arrival in the emergency department, and requirement of ≥2 units of packed red blood cell transfusion. Serum cortisol and serum pituitary hormones (vasopressin [ADH], adrenocorticotrophic hormone [ACTH], thyroid stimulating hormone [TSH], follicular stimulating hormone [FSH], and luteinizing hormone [LH]) were measured in each patient on admission and at 24, 48, 72, and 96 hours after admission. Outcome measure was variation in pituitary hormones.A total of 42 patients were prospectively enrolled; mean age was 37 ± 12 years, mean SBP 85.4 ± 64.5 mmHg, and median Injury Severity Score was 26 (range 18 to 38). There was an increase in the levels of cortisol (p0.001), a decrease in the levels of ACTH (p0.001) and ADH (p0.001), but no change in the levels of LH (p = 0.30), FSH (p = 0.07), and TSH (p = 0.89) over 96 hours. Ten patients died during their hospital stay. Patients who died had higher mean admission ADH levels (p = 0.03), higher mean admission ACTH levels (p0.001), and lower mean admission cortisol levels (p = 0.04) compared with patients who survived.Acute hypopituitarism does not occur in trauma patients with acute hemorrhagic shock. In patients who died, there was a decrease in cortisol levels, which appears to be adrenal in origin.

Introduction Quality improvement initiatives have focused primarily on preventing in-hospital complications. Patients developing complications are at a greater risk of mortality; however, factors associated with failure-to-rescue (death after major complication) in trauma patients remain undefined. The aim of this study was to identify risk factors associated with failure-to-rescue in patients undergoing trauma laparotomy. Methods An -8-year, retrospective analysis of patients undergoing trauma laparotomy was performed. Patients who developed major in-hospital complications were included. Major complications were defined as respiratory, infectious, cardiac, renal, or development of compartment syndrome. Regression analysis was performed to identify independent factors associated with failure-to-rescue after we adjusted for demographics, mechanism of injury, abdominal abbreviated injury scale, initial vital signs, damage control laparotomy, and volume of crystalloids and blood products administered. Results A total of 1,029 patients were reviewed, of which 21% (n = 217) patients who developed major complications were included. The mean age was 39 ± 18 years, 82% were male, 61% had blunt trauma, and median abdominal abbreviated injury scale was 25 [16–34, interquartile range]. Respiratory complications (n = 77) followed by infectious complications (n = 75) were the most common complications. The failure-to-rescue rate was 15.7% (n = 34/217). Age, blunt trauma, severe head injury, uninsured status, and blood products administered on the second day were independent predictor for failure-to-rescue. Conclusion When major complications develop, age, uninsured status, severity of head injury, and prolonged resuscitation are associated independently with failure-to-rescue, whereas initial resuscitation, coagulopathy, and acidosis did not predict failure to rescue. Quality-of-care programs focus in patient level should be on improving the patient's insurance status, preventing secondary brain injury, and further development of resuscitation guidelines.

BACKGROUND: Differences in outcomes among trauma centers (TCs) and non-TCs (NTCs) in patients undergoing emergency general surgery (EGS) are well established. However; the impact of development of certified acute care surgery (ACS) programs on patient outcomes remains unknown. The aim of this study was to evaluate outcomes in patients undergoing EGS across TCs, NTCs, and TCs with ACS (ACS-TC). METHODS: National estimates for EGS procedures were abstracted from the National Inpatient Sample database. Patients undergoing emergent procedures (appendectomy, cholecystectomy, hernia repair, as well as small and large bowel resections) were included. TCs were identified based on American College of Surgeons' verification. ACS-TC programs were recorded from the American Association for the Surgery of Trauma. Outcome measures were hospital length of stay, complications, and mortality. Regression analysis was performed after adjusting for age, sex, race, Charlson comorbidity index, and type of procedure. RESULTS: A total of 131,410 patients undergoing EGS were analyzed. Patients managed in ACS-TCs had shorter hospital stay (p = 0.045) and lower complication rate (p = 0.041) compared with patients managed in both TCs and NTCs. There was no difference in mortality in patients managed across the groups; however, there was a trend toward lower mortality in patients managed in ACS-TCs in comparison with TCs (p = 0.064) and NTCs (p = 0.089). The overall hospital costs were lower for patients managed in ACS-TCs compared with TCs (p = 0.036). CONCLUSION: TCs with ACS have improved outcomes in EGS procedures compared with both TCs and non-TCs. ACS training with the associated infrastructure standards may contribute to these improved outcomes. LEVEL OF EVIDENCE: Therapeutic/care management study, level IV.

Management of traumatic brain injury (TBI) is focused on preventing secondary brain injury. Remote ischemic conditioning (RIC) is an established treatment modality that has been shown to improve patient outcomes secondary to inflammatory insults. The aim of our study was to assess whether RIC in trauma patients with severe TBI could reduce secondary brain injury.This prospective consented interventional trial included all TBI patients admitted to our Level 1 trauma center with an intracranial hemorrhage and a Glasgow Coma Scale (GCS) score of 8 or lower on admission. In each patient, four cycles of RIC were performed within 1 hour of admission. Each cycle consisted of 5 minutes of controlled upper limb (arm) ischemia followed by 5 minutes of reperfusion using a blood pressure cuff. Serum biomarkers of acute brain injury, S-100B, and neuron-specific enolase (NSE) were measured at 0, 6, and 24 hours. Outcome measure was reduction in the level of serum biomarkers after RIC.A total of 40 patients (RIC, 20; control, 20) were enrolled. The mean (SD) age was 46.15 (18.64) years, the median GCS score was 8 (interquartile range, 3-8), and the median head Abbreviated Injury Scale (AIS) score was 3 (interquartile range, 3-5), and there was no difference between the RIC and control groups in any of the baseline demographics or injury characteristics including the type and size of intracranial bleed or skull fracture patterns. There was no difference in the 0-hour S-100B (p = 0.9) and NSE (p = 0.72) level between the RIC and the control group. There was a significant reduction in the mean levels of S-100B (p = 0.01) and NSE (p = 0.04) at 6 hours and 24 hours in comparison with the 0-hour level in the RIC group.This study showed that RIC significantly decreased the standard biomarkers of acute brain injury in patients with severe TBI. Our study highlights the novel therapeutic role of RIC for preventing secondary brain insults in TBI patients.Therapeutic study, level III.

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.

Computed Tomography Angiography (CTA) is being used to identify traumatic intracranial aneurysms (TICA) in patients with findings such as skull fracture and intracranial haemorrhage on initial Computed Tomography (CT) scans after blunt traumatic brain injury (TBI). However, the incidence of TICA in patients with blunt TBI is unknown. The aim of this study is to report the incidence of TICA in patients with blunt TBI and to assess the utility of CTA in detecting these lesions.A 10-year retrospective study (2003-2012) was performed at a Level 1 trauma centre. All patients with blunt TBI who had an initial non-contrasted head CT scan and a follow-up head CTA were included. Head CTAs were then reviewed by a single investigator and TICAs were identified. The primary outcome measure was incidence of TICA in blunt TBI.A total of 10 257 patients with blunt TBI were identified, out of which 459 patients were included in the analysis. Mean age was 47.3 ± 22.5, the majority were male (65.1%) and median ISS was 16 [9-25]. Thirty-six patients (7.8%) had intracranial aneurysm, of which three patients (0.65%) had TICAs.The incidence of traumatic intracranial aneurysm was exceedingly low (0.65%) over 10-years. This study adds to the growing literature questioning the empiric use of CTA for detecting vascular injuries in patients with blunt TBI.

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 (β = -0.4; 95% confidence interval, -6.7 to -0.8; p = 0.01) and age (β = -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. Language: en

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.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.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.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.Therapeutic/care management, level IV.

Direct laryngoscopy (DL) has long been the gold standard for tracheal intubation in emergency and trauma patients. Video laryngoscopy (VL) is increasingly used in many settings and the purpose of this study was to compare its effectiveness to direct laryngoscopy in trauma patients. Our hypothesis was that the success rate of VL would be higher than that of DL. Data were collected prospectively on all trauma patients, from January 2008 to June 2011, who were intubated emergently in an academic level I trauma center. After intubation, the physician that performed the intubation completed a structured data collection form that included demographics, complications, and the presence of difficult airway predictors. Our primary outcome measure was overall successful tracheal intubation, which was defined as successful intubation with the first device used. During the study period, 709 trauma patients were intubated by either VL or DL. VL was performed in 55 % of cases. The overall success rate of VL was 88 % compared to 83 % with DL (P = 0.05). Cervical (C-Spine) immobilization was predictive of higher initial success with VL (87 %) than with DL (80 %) (P

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.

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. Language: en

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 9 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], 1.2Y3.1) operating more than 15 cases per month (OR, 3; 95% CI, 1.2Y8), having more than seven call duties per month (OR, 2.6; 95% CI, 1.2Y6), and with less than 4 hours of relaxation per day (OR, 7; 95% CI, 1.4Y35) 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, 1.1Y8). 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. (J Trauma Acute Care Surg. 2014;77: 148Y154.

Background A definitive consensus on the standardization of practice of a routine repeat head CT (RHCT) scan in patients with traumatic intracranial hemorrhage is lacking. We hypothesized that in examinable patients without neurologic deterioration, RHCT scan does not lead to neurosurgical intervention (craniotomy/craniectomy). Study Design This was a 3-year prospective cohort analysis of patients aged 18 years and older, without antiplatelet or anticoagulation therapy, presenting to our level 1 trauma center with intracranial hemorrhage on initial head CT and a follow-up RHCT. Neurosurgical intervention was defined by craniotomy/craniectomy. Neurologic deterioration was defined as altered mental status, focal neurologic deficits, and/or pupillary changes. Results A total of 1,129 patients were included. Routine RHCT was performed in 1,099 patients. The progression rate was 19.7% (216 of 1,099), with subsequent neurosurgical intervention in 4 patients. Four patients had an abnormal neurologic examination, with a Glasgow Coma Scale (GCS) of ≤8 requiring intubation. Thirty patients had an RHCT secondary to neurologic deterioration; 53% (16 of 30) had progression on RHCT, of which 75% (12 of 16) required neurosurgical intervention. There was an association between deterioration in neurologic examination and need for neurosurgical intervention (odds ratio 3.98; 95% CI 1.7 to 9.1). The negative predictive value of a deteriorating neurologic examination in predicting the need for neurosurgical intervention was 100% in patients with GCS > 8. Conclusions Routine repeat head CT scan is not warranted in patients with normal neurologic examination. Routine repeat head CT scan does not supplement the need for neurologic examination for determining management in patients with traumatic brain injury.

The development of coagulopathy of trauma is multifactorial associated with hypoperfusion and consumption of coagulation factors. Previous studies have compared the role of factor replacement versus FPP for reversal of trauma coagulopathy. The purpose of our study was to determine the time to correction of coagulopathy and blood product requirement in patients who received PCC+FFP compared with patients who received FFP alone.We performed a retrospective analysis of a prospectively maintained database of all coagulopathic (INR ≥ 1.5) trauma patients presenting to our level I trauma center during a 2-years period (2011-2012). Patients were stratified into two groups: patients who received PCC+FFP and patients who received FFP alone. Patients in the two groups were matched in a 1:3 (PCC+FFP:FFP) ratio using propensity score matching for demographics, injury severity, vital parameters, and initial INR. The two groups were then compared for: correction of INR, time to correction of INR, thromboembolic complications, mortality, and cost of therapy.A total of 252 were included in the analysis [PCC+FFP:63; FFP:189]. The mean age was 44 ± 20 years; 70 % were male, with a median ISS score of 27 [16-38]. PCC use was associated with an accelerated correction of INR (394 vs. 1,050 min; p 0.001), reduction in requirement of pack red blood cell (6.6 vs. 10 units; p 0.001) and FFP (2.8 vs. 3.9 units; p 0.01), and decline in mortality (23 vs. 28%; p 0.04). PCC+FFP use was associated with a higher cost of therapy ($1,470 ± 845 vs. 1,171 ± 949; p 0.01) but lower overall cost of transfusion ($7,110 ± 1,068 vs. 9,571 ± 1,524; p 0.01) compared with FFP therapy alone.PCC in conjunction with FFP rapidly corrects INR in a matched cohort of trauma patients not on warfarin therapy compared with FFP therapy alone. The use of PCC as an adjunct to FFP therapy is associated with reduction of blood product requirement and also lowers overall cost.

Protocols call for the start of hormonal therapy with levothyroxine after the declaration of brain death. As the hormonal perturbations occur during the process of brain death, the role of the early initiation of levothyroxine therapy (LT) to salvage organs is not well defined. The aim of this study was to evaluate the impact of early LT (before the declaration of brain death) on the number of solid organs procured per donor.We performed an 8-year retrospective analysis of all trauma patients who progressed to brain death. Patients who consented for organ donation, received LT, and donated solid organs were included. Patients were dichotomized into two groups: early LT group, patients who received LT before the declaration of brain death, and late LT group, those who received LT after brain death. The two groups were compared for differences in demographics, clinical characteristics, need for vasopressor, and number of solid organ donation.A total of 100 solid organ donors were identified of which, 41% (n=77) donors who received LT therapy were included. LT before the declaration of brain death was initiated in 37 patients compared with 40 patients who had it started after the declaration of brain death. There was no difference in demographics between the two groups except that patients in the early LT group were more likely to be hypotensive on presentation (54% vs. 25%, p = 0.001). Early LT therapy was associated with an increase in solid organ procurement rate (odds ratio, 1.9; 95% confidence interval, 1.4-2.7; p = 0.01). Sixty-seven patients donated a total of 291 solid organs.The early use of LT and aggressive blood product resuscitation was associated with a significantly higher number of solid organs donated per donor. Earlier use of LT before the declaration of brain death may be considered in potential organ donors.Therapeutic/care management study, level IV.

It is becoming a standard practice that any "positive" identification of a radiographic intracranial injury requires transfer of the patient to a trauma center for observation and repeat head computed tomography (RHCT). The purpose of this study was to define guidelines-based on each patient's history, physical examination, and initial head CT findings-regarding which patients require a period of observation, RHCT, or neurosurgical consultation.In our retrospective cohort analysis, we reviewed the records of 3,803 blunt traumatic brain injury patients during a 4-year period. We classified patients according to neurologic examination results, use of intoxicants, anticoagulation status, and initial head CT findings. We then developed brain injury guidelines (BIG) based on the individual patient's need for observation or hospitalization, RHCT, or neurosurgical consultation.A total of 1,232 patients had an abnormal head CT finding. In the BIG 1 category, no patients worsened clinically or radiographically or required any intervention. BIG 2 category had radiographic worsening in 2.6% of the patients. All patients who required neurosurgical intervention (13%) were in BIG 3. There was excellent agreement between assigned BIG and verified BIG. κ statistic is equal to 0.98.We have proposed BIG based on patient's history, neurologic examination, and findings of initial head CT scan. These guidelines must be used as supplement to good clinical examination while managing patients with traumatic brain injury. Prospective validation of the BIG is warranted before its widespread implementation.Epidemiologic study, level III.

Smartphones can be used to record and transmit high-quality clinical photographs. The aim of this study was to describe our experience with smartphone telephotography in the care of trauma patients. We hypothesized that smartphone telephotography can be safely and effectively implemented on a trauma service.We performed a 2-year (January 2011-December 2012) prospective analysis of all patient photographs recorded by members of our trauma team at our Level I trauma center. All members of the trauma team recorded patient photographs and e-mailed them to a secure e-mail account. An administrative assistant uploaded a copy of each photgrapho into the patient's electronic medical record. We assessed the number of photographs collected and uploaded, as well as the success, failure, and complication rates.Our trauma team sent 7,200 photographs to a secure e-mail account. Of those, 6,120 (85%) were considered, after an initial review, to be of good quality. Of these, 3,320 photographs (54%) were successfully uploaded into a patient's electronic medical record; the remaining 2,800 photographs lacked adequate labeling and could not be uploaded. The average interval to uploading was 3 months. In total, 10 photographs were uploaded into the wrong patient's electronic medical record, for an error rate of 0.003%. We received only three complaints during the study period.Telephotography can be safely and effectively implemented in trauma clinical practice. Fears of Health Insurance Portability and Accountability Act violations are not valid, as the incidence of patient complaints is minimal when telephotography is implemented under strict guidelines and rules. Dedicated administrative personnel are essential for effective implementation of smartphone photography.

Background Gunshot wounds to the brain are the most lethal of all firearm injuries, with reported survival rates of 10% to 15%. The aim of this study was to determine outcomes in patients with gunshot wounds to the brain, presenting to our institution over time. We hypothesized that aggressive management can increase survival and the rate of organ donation in patients with gunshot wounds to the brain. Study Design We analyzed all patients with gunshot wounds to the brain presenting to our level 1 trauma center over a 5-year period. Aggressive management was defined as resuscitation with blood products, hyperosmolar therapy, and/or prothrombin complex concentrate (PCC). The primary outcome was survival and the secondary outcome was organ donation. Results There were 132 patients with gunshot wounds to the brain, and the survival rates increased incrementally every year, from 10% in 2008 to 46% in 2011, with the adoption of aggressive management. Among survivors, 40% (16 of 40) of the patients had bi-hemispheric injuries. Aggressive management with blood products (p = 0.02) and hyperosmolar therapy (p = 0.01) was independently associated with survival. Of the survivors, 20% had a Glasgow Coma Scale score ≥ 13 at hospital discharge. In patients who died (n = 92), 56% patients were eligible for organ donation, and they donated 60 organs. Conclusions Aggressive management is associated with significant improvement in survival and organ procurement in patients with gunshot wounds to the brain. The bias of resource use can no longer be used to preclude trauma surgeons from abandoning aggressive attempts to save patients with gunshot wound to the brain.

Anticoagulation agents are proven risk factors for intracranial hemorrhage (ICH) in traumatic brain injury (TBI). The aim of our study is to describe the epidemiology of prehospital coumadin, aspirin, and Plavix (CAP) patients with ICH and evaluate the use of repeat head computed tomography (CT) in this group. We performed a retrospective study from our trauma registry. All patients with intracranial hemorrhage on initial CT with prehospital CAP therapy were included. Demographics, CT scan findings, number of repeat CT scans, progressive findings, and neuro-surgical intervention were abstracted. A comparison between prehospital CAP and no-CAP patients was done using χ2 and Mann-Whitney U test. A total of 1606 patients with blunt TBI charts were reviewed of whom 508 patients had intracranial bleeding on initial CT scan and 72 were on prehospital CAP therapy. CAP patients were older ( P < 0.001), had higher Injury Severity Score and head Abbreviated Injury Scores on admission ( P < 0.001), were more likely to present with an abnormal neurologic examination ( P = 0.004), and had higher hospital and intensive care unit lengths of stay ( P < 0.005). Eighty-four per cent of patients were on antiplatelet therapy and 27 per cent were on warfarin. The CAP patients have a threefold increase in the rate of worsening repeat head CT (26 vs 9%, P < 0.05). Prehospital CAP therapy is high risk for progression of bleeding on repeat head CT. Routine repeat head CT remains an important component in this patient population and can provide useful information.

The frailty index (FI) has been shown to predict outcomes in geriatric patients. However, FI has never been applied as a prognostic measure after trauma. The aim of our study was to identify hospital admission factors predicting discharge disposition in geriatric trauma patients.We performed a 1-year prospective study at our Level 1 trauma center. All trauma patients 65 years or older were enrolled. FI was calculated using 50 preadmission variables. Patient's discharge disposition was dichotomized as favorable outcome (discharge home, rehabilitation) or unfavorable outcomes (discharge to skilled nursing facility, death). Multivariate logistic regression was performed to identify factors that predict unfavorable outcome.A total of 100 patients were enrolled, with a mean (SD) age of 76.51 (8.5) years, 59% being males, median Injury Severity Score (ISS) of 14 (range, 9-18), median head Abbreviated Injury Scale (h-AIS) score of 2 (2-3), and median Glasgow Coma Scale (GCS) score of 13 (12-15). Of the patients, 69% had favorable outcome, and 31% had unfavorable outcome. On univariate analysis, FI was found to be a significant predictor for unfavorable outcome (odds ratio, 1.8; 95% confidence interval, 1.2-2.3). After adjusting for age, ISS, and GCS score in a multivariate regression model, FI remained a strong predictor for unfavorable discharge disposition (odds ratio, 1.3; 95% confidence interval, 1.1-1.8).The concept of frailty can be implemented in geriatric trauma patients with similar results as those of nontrauma and nonsurgical patients. FI is a significant predictor of unfavorable discharge disposition and should be an integral part of the assessment tools to determine discharge disposition for geriatric trauma patients.Prognostic study, level II.

One third of US adults are obese. The impact of obesity on outcomes after blunt traumatic injury has been studied with discrepant results. The aim of our study was to evaluate outcomes in morbidly obese patients after blunt trauma. We hypothesized that morbidly obese patients have adverse outcomes as compared with nonobese patients after blunt traumatic injury.We performed a retrospective analysis of all blunt trauma patients (≥18 years) using the National Trauma Data Bank for years 2007 to 2010. Patients with recorded comorbidity of morbid obesity (body mass index ≥ 40) were identified. Patients transferred, dead on arrival, and with isolated traumatic brain injury were excluded. Propensity score matching was used to match morbidly obese patients to non-morbidly obese patients (body mass index40) in a 1:1 ratio based on age, sex, Injury Severity Score (ISS), Glasgow Coma Scale (GCS), and systolic blood pressure on presentation. The primary outcome was mortality, and the secondary outcome was hospital complications.A total of 32,780 patients (morbidly obese, 16,390; nonobese, 16,390) were included in the study. Morbidly obese patients were more likely to have in-hospital complications (odds ratio [OR], 1.8, 95% confidence interval [CI], 1.6-1.9), longer hospital stay (OR, 1.2; 95% CI, 1.1-1.3), and longer intensive care unit stay (OR, 1.15; 95% CI, 1.09-1.2). The overall mortality rate was 2.8% (n = 851). Mortality was higher in morbidly obese patients compared with the nonobese patients (3.0 vs. 2.2; OR, 1.4; 95% CI, 1.1-1.5).In a cohort of matched patients, morbid obesity is a risk factor for the development of in-hospital complications and mortality after blunt traumatic injury. The results of our study call for attention through focused injury prevention efforts. Future studies are needed to help define the consequences of obesity that influence outcomes.Prognostic study, level III.

Alcohol use may alter mental status and vital signs in injured patients, leading to increased testing during emergency department (ED) evaluation. We hypothesized that alcohol use increases the hospital charges when caring for these injured patients.The National Hospital Ambulatory Medical Care Survey collects weighted population-based estimates of ED use. We analyzed injury-related visits of adult patients, and resource use and admission rates were compared by the presence of alcohol.Alcohol was involved in 6.0% of injury-related ED visits. Alcohol-present patients arrived by ambulance more frequently (45% vs 21%, P.001), had a 26% longer ED stay (211 vs 167 minutes, P.001), and underwent more diagnostic testing. They were twice as likely to be admitted (14.0% vs 6.5%, P.001). Additional ED charges were over $217 million.Patients with alcohol-related injuries use significantly more resources, with a significant added financial burden. Insurance companies in many states can deny coverage for injuries caused by alcohol use, shifting these expenses to trauma centers.

BACKGROUND: Coagulopathy in patients with traumatic brain injury (TBI) is a well-studied concept. Prothrombin complex concentrate (PCC) has been shown to be an effective treatment modality for correction of TBI coagulopathy. However, its use and effectiveness compared with recombinant factor VII (rFVIIa) in TBI has not been established. The purpose of this study was to compare PCC and rFVIIa for the correction of TBI coagulopathy. METHODS: All patients with a TBI and an induced or acquired coagulopathy whom received rFVIIa or PCC at our Level I trauma center during a 4-year period were reviewed. Data collected included demographics, changes in international normalized ratio and blood products transfusion, craniotomy rates, and time to neurosurgical intervention, thromboembolic complications, and mortality differences. RESULTS: The study was composed of 85 TBI patients, of whom 64 patients received PCC while 21 patients received rFVIIa. PCC group were more likely to be on coumadin (44% vs. 14%, p = 0.01). There was a significant decline in packed red blood cell transfusion and fresh frozen plasma after PCC administration (p < 0.01). There was no statistically significant difference in the craniotomy rate (28% vs. 10 %, p = 0.1) or the mean time to intervention between the two groups (201 [33] vs. 230 [10], p = 0.9). Mortality rates were lower in the PCC group compared with rFVIIa (67% vs. 47%, p = 0.02). Subsequent thromboembolic event was seen in one patient on rFVIIa. Mean cost of treatment per patient on PCC was $1,007 compared with $5,757 for rFVIIa (p < 0.01). CONCLUSION: PCC is safe and effective for treating coagulopathy in TBI patients, while reducing costs and resource use. PCC should be considered as an effective therapy to treat both acquired and induced coagulopathy in TBI with or without prehospital coumadin use. LEVEL OF EVIDENCE: Therapeutic study, level IV.

Early seizures after severe traumatic brain injury (TBI) have a reported incidence of up to 15 %. Prophylaxis for early seizures using 1 week of phenytoin is considered standard of care for seizure prevention. However, many centers have substituted the anticonvulsant levetiracetam without good data on the efficacy of this approach. Our hypothesis was that the treatment with levetiracetam is not effective in preventing early post-traumatic seizures. All trauma patients sustaining a TBI from January 2007 to December 2009 at an urban level-one trauma center were retrospectively analyzed. Seizures were identified from a prospectively gathered morbidity database and anticonvulsant use from the pharmacy database. Statistical comparisons were made by Chi square, t tests, and logistic regression modeling. Patients who received levetiracetam prophylaxis were matched 1:1 using propensity score matching with those who did not receive the drug. 5551 trauma patients suffered a TBI during the study period, with an overall seizure rate of 0.7 % (39/5551). Of the total population, 1795 were diagnosed with severe TBI (Head AIS score 3–5). Seizures were 25 times more likely in the severe TBI group than in the non-severe group [2.0 % (36/1795) vs. 0.08 % (3/3756); OR 25.6; 95 % CI 7.8–83.2; p

BACKGROUND For patients who present to the emergency department (ED) with symptomatic cholelithiasis, surgery is indicated only if they are diagnosed of acute cholecystitis (AC). We hypothesized that, because preoperative signs and diagnostic tests are not sensitive enough to diagnose AC, coupled with the potential health care burden of non-AC gallbladder, surgery may be offered sooner. METHODS We prospectively evaluated 200 patients who presented to ED with clinical suspicion of gallbladder disease, including a right upper quadrant/epigastric abdominal pain and cholelithiasis, and who underwent laparoscopic cholecystectomy. We correlated the preoperative clinical findings, including ultrasonography results, with the surgeon's intraoperative assessment (OR-GB) and with the pathology report (PA-GB). A multiple logistic regression model was performed. RESULTS Of the gallbladders, 116 were declared AC by OR-GB but only 54 by PA-GB, (r = 0.31, p < 0.001). The median time to surgery was 17 hours; 75% of the patients underwent surgery within 24 hours. The sensitivity of ultrasonography for AC according to PA-GB was 38%, and 16% when combined all preoperative findings. Both figures dropped to 27% and 11% when correlated to OR-GB. Our regression identified persistent abdominal pain, positive ultrasonography result, and a body mass index of greater than 40 to be significant predictors of AC according to PA-GB; however, only the persistent abdominal pain remained significant according to OR-GB. CONCLUSION The study confirmed the lack of sensitivity of signs and diagnostic tools to diagnose AC. Because of the acute care surgery model, we believe that the approach to the patients who present to the ED with suspected gallbladder disease is to offer them surgery as soon as feasible, with or without AC. This approach will avoid an unnecessary delay as well as quickly relieve patient's pain and suffering; the health care system will benefit from a cost-effective reduction in number of outpatient referrals and repeated ED visits. LEVEL OF EVIDENCE Diagnostic study, level II.

OBJECTIVES: The popularity of all-terrain vehicles (ATVs) continues to increase, but this form of recreation is not as well regulated and can impact children disproportionately. This study examines the epidemiology of ATV injuries in Arizona with emphasis on pediatric injuries and compares ATV injuries to those associated with motorcycle (MCC) and motor vehicle crashes (MVC). METHODS: The trauma registry of a level 1 trauma center was used to identify all ATV crashes during a 5-year period (2004-2008) in patients younger than 16 years. Registration data of ATV were obtained from the state DMV. All-terrain vehicle-related injuries were compared with both MVC and MCC. RESULTS: A total of 250 pediatric ATV crashes were observed during the 5-year period, rising from 29 in 2004 to 53 in 2008. The median age of patients with ATV-related injuries was 13 years, which is higher than that of patients with MVC-related injuries (9 years). Only 34% of the patients with ATV-related injuries were helmeted, compared with 55% of patients with MCC-related injuries. All-terrain vehicle-related crashes were at least 30 times more likely than MVCs and almost 20 times more likely than MCCs. Statewide pediatric ATV deaths rose during the study period. CONCLUSIONS: All-terrain vehicle-related crashes have increased during this study period and have become a significant source of injuries. Public education and awareness of the dangers associated with ATV use need to be targeted toward both parents and children likely to use ATVs. Language: en

Background The aim of this study was to prospectively duplicate previous retrospective findings showing that prestorage leukoreduction blunts the detrimental effect of aging on banked packed red blood cells transfused after injury. Methods Over 19 months, trauma patients transfused with ≥4 U of packed red blood cells and surviving ≥24 hours were followed. The age of each unit was collected. Results The cohort consisted of 153 patients. All models showed no association between advancing blood age and the likelihood of developing multiple-organ dysfunction syndrome or infections, regardless of whether the mean age of blood was analyzed as a continuous variable, as a percentage of blood received that was 14 or Conclusions This prospective study duplicates previous retrospective findings of an abrogation of the detrimental effects of advancing mean packed red blood cell age on outcomes after trauma by performing prestorage leukoreduction.

The use of pulmonary artery catheter (PAC) is controversial. The purpose of this study was to document the changing pattern of PAC use and to determine its effect on outcome.The use of PAC was analyzed in patients ≥16 years old admitted to the surgical intensive care unit (SICU) over a 9-year period starting in 2000. Patients with SICU length of stay exceeding 30 days were excluded. For the evaluation of PAC's effect on outcome, PAC and no-PAC patients were matched utilizing propensity scores.During the 9-year study period, a total of 5,192 trauma patients were admitted to the SICU. Of these, 426 (8.2%) were16 years old, and 174 (3.4%) had a SICU length of stay that exceeded 30 days. For the remaining 4,592 patients, the mean ± SD age was 39.5 ± 18.8 years, and the mean ISS was 19.9 ± 12.4. PAC was utilized in 19.5% (n = 896) of all the patients admitted to the SICU. The trend for PAC use decreased significantly over the years (P value for trend0.001), from 38.6% in the year 2000 to 4.2% in the year 2008. This decrease was noted in all age and injury severity groups of patients. The overall mortality, however, remained at the same levels (P value for trend = 0.111). Patients managed with a PAC were significantly older, more severely injured, more frequently injured by a blunt mechanism, and were admitted more often in a hypotensive or comatose status. In the early part of the study, the PAC was utilized on the first day and for 4.1 days on average. In the later part of the study, however, the PAC was used on the second day and for a shorter period of time (3 days on average, P0.001). In the matched study population, patients in the PAC group had almost twofold higher odds for death, when compared to the no-PAC group [34.2% vs. 22.5%, Odds Ratio (95% CI): 1.78 (1.42, 2.26), P0.001]. Patients younger than 50 years of age who had an ISS ≥16 had worse outcome when managed with a PAC, whereas patients aged 30-69 years with an ISS16 had a higher survival. The overall complication rate was fivefold higher in patients receiving a PAC [46.3% vs. 14.2%, Odds Ratio (95% CI): 5.22 (4.04, 6.74), P0.001].The use of PAC has decreased almost 10-fold over the last decade at our institution. The PAC is being used later during the ICU course and for a shorter period of time. In a matched population, the use of PAC is associated with a significantly higher mortality and complication rate, but the reason for this association remains uncertain. The use of PAC is invasive and is associated with known complications and financial costs. While the use of PAC maybe useful in a select population, routine and widespread use of the PAC should be avoided.

Rural trauma care has been regarded as being the "challenge for the next decade." Trauma patients in rural areas face more struggles than their urban counterparts because of the absence of specialized trauma care, delay in providing immediate care to trauma victims, and longer transport times to reach a trauma center. Telemedicine is a promising tool for facilitating rural trauma care. This stellar tool creates a real-time link between a remotely located specialist and the local healthcare provider, especially during the initial management of the trauma patient, involving resuscitation and even intubation. However, the high cost of purchasing, setting up, and maintaining all the needed equipment has made telemedicine an expensive proposition for rural hospitals, which frequently have limited budgets. But recently, new improvements in communication technology have made smartphones an indispensable part of daily life, even in rural areas. These devices have great potential to improve patient care and enhance medical education because of their wide adoption and ease of use. In this article, we describe our initial teletrauma experience and the effect of smartphone implementation in patient care and medical education at the University of Arizona Medical Center in Tucson.

Background The infectious risks of parenteral nutrition (PN) in critical illness are well described, although most literature predates tight glucose control (TGC) practice. The authors hypothesized that PN-related complications are ameliorated by TGC and are equivalent to those in enteral nutrition (EN) patients. Methods A prospective cohort study of patients admitted to the surgical intensive care unit was conducted, comparing PN and EN patients. TGC target was 80 to 110 mg/dL. Univariate and multivariate logistic regression was used to explore the association between infectious outcomes and PN use. Results One hundred fifty-five patients were studied. Mean daily glucose values were lower for the PN group than for the EN patients (118.2 vs 125.6 mg/dL, P = .002). Nonetheless, the incidence of bloodstream infection and catheter-related bloodstream infection was significantly associated with the administration of PN. In a multivariate logistic regression model, PN was associated with a >4-fold increase in the odds of having a catheter-related bloodstream infection (odds ratio, 4.48; 95% confidence interval, 1.14–17.49; P = .03). Conclusions Despite the successful implementation of TGC, PN is still a significant risk factor for infectious complications among surgical intensive care unit patients.

Previous studies have demonstrated that the transfusion of older blood is independently associated with higher rates of infectious complications, multiple organ failure, and mortality. Putative mechanisms implicate leukocytes in stored blood that generate immunomodulatory mediators as the stored blood ages. The purpose of this retrospective cohort study was to describe the effect of prestorage leukoreduction (PS-LR) on the detrimental clinical effects of increasing age on blood products used in trauma patients.All patients receivingor=6 units of packed red cells and survivingor=48 hours since May 1999 when institutional universal PS-LR was begun were identified. Transfusion requirements, demographic data, and causes of death were collected. Blood bank records were reviewed to determine the age of each unit of blood transfused. Multivariate logistic regression was used to determine the relationship between the age of PS-LR transfused blood and mortality after adjusting for total transfusion requirement, patient age, Injury Severity Score, head Abbreviated Injury Score, mechanism of injury, and gender. A subgroup analysis was performed excluding those patients in whom care was withdrawn at 48 hours to 72 hours postinjury for brain death or neurologic devastation.A total of 399 patients, receiving 6,603 units of blood, met inclusion criteria. Mortality analysis showed that increasing Injury Severity Score, patient age, head Abbreviated Injury Score, and number of units of packed red cells transfused were all independently associated with an increased risk of death. When mean age of blood was analyzed as a continuous variable, a significant reduction in the risk of death with increasing mean age of transfused PS-LR blood was noted (odds ratio [OR], 0.959; 95% confidence interval [CI], 0.924-0.996). Both of these findings persisted when the mean age of blood was dichotomized at 14 days (OR, 0.426; 95% CI, 0.182-0.998) and 21 days (OR, 0.439; 95% CI, 0.225-0.857). The area under the curve for the receiver operating characteristics of our mortality model was 0.90. After excluding 13 patients in whom care was withdrawn 48 hours to 72 hours postinjury for brain death or neurologic devastation, the mortality analysis still showed that increasing injury severity, number of units of packed red cells transfused, and age were all independently associated with an increased risk of death. The protective effect of receiving older blood seen in the all-cause mortality analysis disappeared because no association was found between odds of dying and increasing age of packed red blood cells units transfused. This was true whether the mean age of transfused blood was dichotomized at 14 days (OR, 0.93; CI, 0.30-2.83) or at 21 days (OR, 0.54; CI, 0.25-1.16).Our data suggest that the deleterious effects of aging on banked blood are ameliorated by PS-LR. We are currently conducting a prospective observational study in an effort to duplicate the findings of this retrospective investigation.

Background: Trauma surgery is in constant evolution as is the use of damage control laparotomy (DCL). The purpose of this study was to report the change in usage of DCL over time and its effect on outcome. Methods: Trauma patients requiring laparotomies during a 3-year (2006-2008) period were reviewed. DCL was defined as laparotomy when fascia was not closed at the first operation. Results: There were 14,534 trauma patients evaluated, and 843 laparotomies were performed on 532 patients during the study period. The number of patients requiring open laparotomies slightly increased while the demographics and Injury Severity Score were similar during the study period. The number of patient requiring DCL significantly decreased from 36.3% (53 of 146) in 2006 to 8.8% (15 of 170) in 2008 (p < 0.001). During this same time period, the mortality rate for patients requiring open laparotomy significantly decreased from 21.9% in 2006 to 12.9% in 2008 (p = 0.05). The decreased use of DCL resulted in a 33.3% reduction in the number of laparotomies performed. The decrease in average costs and charges is projected to result in savings of $2.2 million and $5.8 million, respectively. Conclusions: The use of DCL was significantly decreased by 78% during the study with significantly improved outcome. The improved outcome and decreased resource utilization can reduce health care costs and charges. Although DCL may be a vital aspect of trauma surgery, it can be used more selectively with improved outcome.

Background: To examine police compliance with policies for the proper use of conductive electrical devices (CEDs) and, in turn, track any associated medical events following CED application. Methods: Prospective, population-based, 15-month study of police activations of CEDs after their introduction into the police force of a large U.S. city (residential population, 1.25 million). Local policy for use was consistent with the recommendations of International Association of Chiefs of Police. Data collected included age, sex, predefined rationale for use, target distance, activation duration, total energy delivered, policy compliance, and medical findings or events within the first 12 hours. Results: Among 426 consecutive CED activations (November 1, 2004 through January 31, 2006), the suspects' mean age (years ± standard deviation) was 30 ± 10 (range, 13-72) years and 90.4% were male. Suspects' mean distance from the officer was 5.0 ± 4.5 feet (range, 0-21). Reasons for use included: evading or resisting arrest (33.3%, n = 142), public intoxication or disorderly conduct (15.8%, n = 76), interrupting a felony in progress (9.3%, n = 45), and interrupting an assault on an officer or public servant (6.0%, n = 29). Mean total duration of exposures was 8.6 ± 5.9 seconds, and total energy delivered per suspect was 227 ± 156 joules. Officers followed policy in all cases and, accordingly, all suspects rapidly received medical evaluation or simple first aid. No suspect required further treatment except one who was later found to have severe toxic hyperthermia and who died within 2 hours of activation despite rapid on-scene intervention. In 5.4% of deployments (n = 23), CED use was deemed to have dearly prevented the use of lethal force by police. Conclusion: Police were compliant with policy in all cases, and, in addition to avoiding the use of lethal force in a significant number of circumstances, the safety of CED use was demonstrated despite one death subsequently attributed to lethal toxic hyperthermia. Collaborative nationwide research using similar registries is strongly recommended to document compliance and ensure ongoing safety monitoring.

Background Cardioprotection with beta-receptor antagonists improves outcome in high risk patients undergoing elective surgery. Recent trials have demonstrated an association between beta blocker (BB) use and improved outcomes after injury. The mechanisms through which BB result in improved outcomes remain poorly elucidated. In vitro evidence supports that BB modulates the postinjury inflammatory response. The purpose of this study was to examine the effects of BB on inflammatory profiles in injured patients at increased risk for heart disease. Methods A pseudo-randomized, controlled trial of injured patients over 55 admitted to the intensive care unit was conducted. Patients were randomized to receive continuous BB or standard of care. Patients with a reported history of prehospital BB use were enrolled into an observational arm of the trial, continued on BB, and analyzed with the continuous BB group. Plasma interleukin (IL)-6 and IL-1beta levels were measured by enzyme-linked immunosorbent assay at baseline and day 1, 2, and 4 after BB initiation. Cytokine data were log transformed for normality assumptions. Repeated measures analysis of variance was used to test for within-group differences in cytokine levels over time. Results Forty-two patients were enrolled. Seventeen patients were randomized to the control group and 25 patients received continuous BB (10 randomized/15 observational). There was no difference in gender, age, prior history of heart disease, or admission heart rate, systolic blood pressure or initial base deficit between groups. Baseline levels of IL-6 and IL-1beta did not differ between groups. Levels of IL-6, but not IL-1beta, decreased over time in patients receiving BB (p = 0.04), whereas levels in controls remained unchanged (p = 0.27). There were no BB related complications. Conclusions Use of BB decreases serum IL-6 levels over time in injured patients at risk for heart disease. This may contribute to improved outcomes noted in trauma patients receiving BB. Additionally, BB use in this population of patients is safe after endpoints of resuscitation have been met.

Background: Excessive volume resuscitation after injury is associated with severe complications. B-type natriuretic peptide (BNP) is secreted from myocardium under increased wall stretch and is used in medical intensive care units (ICUs) as a noninvasive method to detect heart failure. However, the use of BNP as a marker of fluid overload during resuscitation from injury has not been previously described. Methods: Serum BNP levels were prospectively followed in 134 trauma ICU patients. Levels were obtained at admission and at 12, 24, and 48 hours. Repeated measures analysis of variance was used to test for differences in BNP levels over time. Post hoc pairwise comparisons were made with Bonferroni correction when the omnibus test indicated significance. Chest films were obtained at 24 hours and scored for the presence of pulmonary edema by a radiologist blinded to BNP measurements (n = 45). Twenty-four hour BNP levels for patients with or without radiographic evidence of pulmonary edema were compared using nonparametric analysis (Mann-Whitney U). Results: Admission BNP levels were low and increased with fluid resuscitation over time in all patients (p = 0.002) as well as in a subgroup of patients

IMPORTANCE: Domestic violence is an extremely underreported crime and a growing social problem in the United States. However, the true burden of the problem remains unknown. OBJECTIVE: To assess the reported prevalence of domestic violence among trauma patients. DESIGN, SETTING, AND PARTICIPANTS: A 6-year (2007-2012) retrospective analysis of the prospectively maintained National Trauma Data Bank. Trauma patients who experienced domestic violence and who presented to trauma centers participating in the National Trauma Data Bank were identified using International Classification of Diseases, Ninth Revision diagnosis codes (995.80-995.85, 995.50, 995.52-995.55, and 995.59) and E codes (E967.0-E967.9). Patients were stratified by age into 3 groups: children ( DESIGN, SETTING, AND PARTICIPANTS: ≤18 years), adults (19-54 years), and elderly patients (≥55 years). Trend analysis was performed on April 10, 2014, to assess the reported prevalence of domestic violence over the years. PARTICIPANTS: Trauma patients presenting to trauma centers participating in the National Trauma Data Bank. MAIN OUTCOMES AND MEASURES: To assess the reported prevalence of domestic violence among trauma patients. RESULTS: A total of 16 RESULTS: 575 trauma patients who experienced domestic violence were included. Of these trauma patients, 10 224 (61.7%) were children, 5503 (33.2%) were adults, and 848 (5.1%) were elderly patients. The mean (SD) age was 15.9 (20.6), the mean (SD) Injury Severity Score was 10.9 (9.6), and 8397 (50.7%) we RESULTS: re male patients. Head injuries (46.8% of patients) and extremity fractures (31.2% of patients) were the most common injuries. A total of 12 515 patients (75.1%) were discharged home, and the overall mortality rate was 5.9% (n = 980). The overall reported prevalence of domestic violence among RESULTS: trauma patients was 5.7 cases per 1000 trauma center discharges. The prevalence of domestic violence increased among children (14.0 cases per 1000 trauma center discharges in 2007 to 18.5 case per 1000 trauma center discharges in 2012; P = .001) and adults (3.2 cases per 1000 discharges in 2007 RESULTS: to 4.5 cases per 1000 discharges in 2012; P = .001) over the 6-year period and remained unchanged for elderly patients (0.8 cases per 1000 discharges in 2007 to 0.96 cases per 1000 discharges in 2012; P = .09). On subanalysis of adults and elderly patients, the prevalence of domestic violenc RESULTS: e increased among both female (4.6 cases per 1000 discharges in 2007 to 5.3 cases per 1000 discharges in 2012; P = .001) and male patients (1.5 cases per 1000 discharges in 2007 to 2.8 cases per 1000 discharges in 2012; P = .001). CONCLUSIONS AND RELEVANCE: Domestic violence is prevalent among trauma patients. Over the years, the reported prevalence of domestic violence has been increasing among children and adults, and continues to remain high among female trauma patients. A robust mandatory screening for evaluating domestic violence among trauma patients, along with a focused national intervention, is warranted. Language: en

Background The use of prothrombin complex concentrate (PCC) to reverse acquired (coagulopathy of trauma) and induced coagulopathy (preinjury warfarin use) is well defined. Objective To compare outcomes in patients with traumatic brain injury without warfarin therapy receiving PCC as an adjunct to fresh frozen plasma (FFP) therapy compared with patients receiving FFP therapy alone. Methods All patients with traumatic brain injury coagulopathy without warfarin therapy who received PCC (25 IU/kg) in conjunction with FFP or FFP alone at our Level I trauma center were reviewed. Coagulopathy was defined as an international normalized ratio >1.5. The groups (PCC + FFP vs FFP alone) were matched using propensity score matching on a 1:2 ratio for age, sex, Glasgow Coma Scale score, Injury Severity Score, head Abbreviated Injury Scale score, and international normalized ratio (INR) on presentation. The primary outcome measure was time to craniotomy. Secondary outcome measures were blood product requirements, cost of therapy, and mortality. Results A total of 1641 patients were reviewed, 222 of whom were included (PCC + FFP, 74; FFP, 148). The mean ± standard deviation age was 46.4 ± 21.7 years, the median (range) Glasgow Coma Scale score was 8 (3-12), and the mean ± standard deviation INR on presentation was 1.92 ± 0.6. PCC + FFP therapy was associated with an accelerated correction of INR (P = .001) and decrease in overall pack red blood cell (P = .035) and FFP (P = .041) administration requirement. Craniotomy was performed in 26.1% of patients (n = 58). Patients who received PCC + FFP therapy had faster time to craniotomy (P = .028) compared with patients who received FFP therapy alone. Conclusion PCC as an adjunct to FFP decreases the time to craniotomy with faster correction of INR and concomitant decrease in the need for blood product requirement in patients with traumatic brain injury exclusive of prehospital warfarin therapy.

OBJECTIVES: To determine whether frail elderly adults are at greater risk of fracture after a ground-level fall (GLF) than those who are not frail. DESIGN: Prospective observational study. SETTING: Level 1 trauma center. PARTICIPANTS: All elderly (≥65) adults presenting after a GLF over 1 year (N = 110; mean age ± SD 79.5 ± 8.3, 54% male). MEASUREMENT: A Frailty Index (FI) was calculated using 50 preadmission frailty variables. Participants with a FI of 0.25 or greater were considered to be frail. The primary outcome measure was a new fracture; 40.1% (n = 45) of participants presented with a new fracture. The secondary outcome was discharge to an institutional facility (rehabilitation center or skilled nursing facility). Multivariate logistic regression was performed. RESULTS: Forty-three (38.2%) participants were frail. The median Injury Severity Score was 14 (range 9-17), and the mean FI was 0.20 ± 0.12. Frail participants were more likely than those who were not frail to have fractures (odds ratio (OR) = 1.8, 95% confidence interval (CI) = 1.2-2.3, P = .01). Thirty-six (32.7%) participants were discharged to an institutional facility. Frail participants were more likely to be discharged to an institutional facility (OR = 1.42, 95% CI = 1.08-3.09, P = .03) after a GLF. CONCLUSION: Frail individuals have a higher likelihood of fractures and discharge to an institutional facility after a GLF than those who are not frail. The FI may be used as an adjunct for decision-making when developing a discharge plan for an elderly adult after a GLF. Language: en

Sleep is an important physiologic process, and lack of sleep is associated with a host of adverse outcomes. Basic and clinical research has documented the important role circadian rhythm plays in biologic function. Critical illness is a time of extreme vulnerability for patients, and the important role sleep may play in recovery for intensive care unit (ICU) patients is just beginning to be explored. This concise clinical review focuses on the current state of research examining sleep in critical illness. We discuss sleep and circadian rhythm abnormalities that occur in ICU patients and the challenges to measuring alterations in circadian rhythm in critical illness and review methods to measure sleep in the ICU, including polysomnography, actigraphy, and questionnaires. We discuss data on the impact of potentially modifiable disruptors to patient sleep, such as noise, light, and patient care activities, and report on potential methods to improve sleep in the setting of critical illness. Finally, we review the latest literature on sleep disturbances that persist or develop after critical illness.

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.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 (ISS5) 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.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.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.Epidemiologic study, level III. Therapeutic study, level IV.

BACKGROUND: Trauma centers often receive transfers from lower-level trauma centers or nontrauma hospitals. The aim of this study wasto analyze the incidence and pattern of secondary overtriage to our Level I trauma center.METHODS: We performed a 2-year retrospective analysis of all trauma patients transferred to our Level I trauma center and dischargedwithin 24hoursof admission. Reasonfor referral,referring specialty, modeof transport,and intervention detailswere collected.Outcomes measures were incidence of secondary overtriage as well as requirement of major or minor procedure. Major proce-durewas defined as surgical intervention in the operating room. Minor procedureswere defined as procedures performed in theemergency department.RESULTS: A total of 1,846 patients were transferred to our Level I trauma center, of whom 440 (24%) were discharged within 24 hoursof admission. The mean (SD) age was 35 (21) years, 72% were male, and mean (SD) Injury Severity Score (ISS) 4 (4). Themost common reasons for referral were extremity fractures (31%), followed by head injury (23%) and soft tissue injuries (13%).Of the 440 patients discharged within 24 hours, 380 (86%) required only observation (268 of 380) or minor procedure (112of 380). Minor procedureswere entirely consisted offracture management (n = 47, 42%) and wound care (n = 65, 58%). Themean (SD) interfacility transfer distance was 45 (46) miles. Mean (SD) hospital charges per transfer were $12,549 ($5,863).CONCLUSION: A significant number of patients transferred to our trauma center were discharged within 24 hours; most of them requiredobservation and/or minor procedures.

Platelet dysfunction has been attributed to progression of initial intracranial hemorrhage (ICH) on repeat head computed tomographic (RHCT) scans in patients on prehospital antiplatelet therapy. However, there is little emphasis on the effect of platelet count and progression of ICH in patients with traumatic brain injury. The aim of this study was to determine the platelet count cutoff for progression on RHCT and neurosurgical intervention in patients on antiplatelet therapy.We performed a prospective cohort analysis of all traumatic brain injury patients with an ICH on prehospital antiplatelet therapy. Antiplatelet therapy was defined as aspirin, clopidogrel, or a combination of both. Admission platelet count was recorded and used for analysis. Receiver operating characteristic curves were plotted to identify the optimal platelet count for progression on RHCT scan and neurosurgical intervention in patients on antiplatelet therapy.A total of 264 patients were enrolled. Platelet count of 135,000/µL or less (area under the curve, 0.80) and platelet count of 95,000/µL or less (area under the curve, 0.92) were the optimal threshold points for progression on RHCT scan and neurosurgical intervention, respectively. Patients with platelet count of 135,000/µL or less were 12.4 times (95% confidence interval, 7.1-18.4) more likely to have progression on RHCT scan and patients with platelet count 95,000/µL or less were 31.5 times (95% confidence interval, 19.7-96.2) more likely to require neurosurgical intervention.A platelet count of less than 135,000/µL in patients on antiplatelet therapy is predictive of both radiographic and clinical worsening. This is a clinically relevant target intended to help tailor and improve management in patients on antiplatelet therapy.Therapeutic study, level III.

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).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).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 deficit4 were 21-times more likely to have a neurosurgical intervention.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.

Background Brain Trauma Foundation (BTF) guidelines recommend intracranial pressure (ICP) monitoring for traumatic brain injury (TBI) patients with a Glasgow Coma Scale score of 8 or less with an abnormal head computed tomography, or a normal head computed tomography scan with systolic blood pressure ≤90 mm Hg, posturing, or in patients of age ≥40. The benefits of these guidelines on outcome remain unproven. We hypothesized that adherence to BTF guidelines for ICP monitoring does not improve outcomes in patients with TBI. Methods All TBI patients with an admission Glasgow Coma Scale ≤8 admitted to our level I trauma center over a 3-y period were identified. Adherence to the individual components of our institutional TBI Bundle (ICP monitoring, SpO2 ≥95%, PaCO2 30–39 mm Hg, systolic blood pressure ≥90 mm Hg, cerebral perfusion pressure ≥60 mm Hg, ICP ≤25 mm Hg, and temperature 36°C–37°C) was assessed. Patients were stratified into two groups as follows: patients with ICP monitoring (ICP) and patients without ICP monitoring (no-ICP). Outcome measures were survival and discharge disposition. Multivariate regression analysis was performed. Results We identified 2618 TBI patients, 261 of whom met the BTF criteria for ICP monitoring. After excluding those with nonsurvivable injuries (n = 67), 194 patients were available for analysis. The two groups were similar in demographics and severity of head injury. Survival rate was higher in the no-ICP group compared with that in the ICP group (98% versus 76%, P
