Is there a role for REBOA? A system assessment.

INTRODUCTION: To analyze our experience to quantify potential need for resuscitative endovascular balloon occlusion of the aorta (REBOA). METHODS: Retrospective review of patients over a three-year period who presented as a trauma with hemorrhagic shock. Patients were divided into two groups: REBOA Candidate vs. Non-candidates. Injuries, outcomes, and interventions were compared. RESULTS: Of 7643 trauma activations, only 37 (0.44%) fit inclusion criteria, of which 16 met criteria for candidacy for potential REBOA placement. The groups did not differ in terms of injury severity, physiology, age, timing of intervention, nor massive transfusion. Survival was linked to TRISS (p = 0.01) and Emergency Room Thoracotomy (p = 0.002). Of Candidates, 8 (50%) had injuries that could have benefited from REBOA, while 7 (44%) had injuries that could be associated with potential harm. DISCUSSION: The volume of patients who would potentially benefit from REBOA appears to be small and does not appear to support system wide adoption in the studied region. LEVEL OF EVIDENCE: IV.

Nationwide Assessment of Factors Associated with Nonoperative Management of Pediatric Splenic Injury.

To evaluate variation in care nationwide for children with splenic injuries at pediatric trauma, adult trauma, and nontrauma centers. We used the National Inpatient Sample from 2001 to 2010 to identify pediatric patients with splenic injury. We analyzed demographic, clinical, and hospital status characteristics. The primary objective was comparison of splenectomy rates at pediatric, adult, and nontrauma centers. We identified 34,599 patients with splenic injury. Throughout the study, 3,979 (11.5%) patients underwent splenectomy: 8.2 per cent of patients at pediatric trauma, 17.6 per cent at adult trauma, and 14.5 per cent at nontrauma centers. Multivariate regression analysis demonstrated patients had decreased odds of splenectomy at pediatric trauma centers compared with adult and nontrauma centers (OR = 0.42, P < 0.001). In addition, children aged 14 to 17 years (OR = 2.5) with injury severity score > 14 (OR = 5.8) had increased odds of undergoing splenectomy. In this nationwide sample, children with splenic injury treated at adult trauma and nontrauma centers had significantly higher rates of splenectomy compared with children treated at pediatric trauma centers. We highlight the need for interventions that ensure all injured children receive appropriate and high quality trauma care.

Methods for Early Control of Abdominal Hemorrhage: An Assessment of Potential Benefit.

BACKGROUND: Noncompressible truncal hemorrhage (NCTH) after injury is associated with a mortality increase that is unchanged during the past 20 years. Current treatment consists of rapid transport and emergent intervention. Three early hemorrhage control interventions that may improve survival are placement of a resuscitative endovascular balloon occlusion of the aorta (REBOA), injection of intracavitary self-expanding foam, and application of the Abdominal Aortic Junctional Tourniquet (AAJT™). The goal of this work was to ascertain whether patients with uncontrolled abdominal or pelvic hemorrhage might benefit by the early or prehospital use of one of these interventions. METHODS: This was a single-center retrospective study of patients who received a trauma laparotomy from 2013 to 2015. Operative reports were reviewed. The probable benefit of each hemorrhage control method was evaluated for each patient based on the location(s) of injury and the severity of their physiologic derangement. The potential scope of applicability of each control method was then directly compared. RESULTS: During the study period, 9,608 patients were admitted; 402 patients required an emergent trauma laparotomy. REBOA was potentially beneficial for hemorrhage control in 384 (96%) of patients, foam in 351 (87%), and AAJT in 35 (9%). There was no statistically significant difference in the potential scope of applicability between REBOA and foam (ρ = .022). There was a significant difference between REBOA and AAJT (ρ < .001) and foam and AAJT™ (ρ < .001). The external surface location of signs of injury did not correlate with the internal injury location identified during laparotomy. CONCLUSION: Early use of REBOA and foam potentially benefits the largest number of patients with abdominal or pelvic bleeding and may have widespread applicability for patients in the preoperative, and potentially the prehospital, setting. AAJT may be useful with specific types of injury. The site of bleeding must be considered before the use of any of these tools.

Early mobilization of patients with non-operative liver and spleen injuries is safe and cost effective.

PURPOSE: There is no standard protocol for the management of non-operative liver or spleen injuries (LSI). In 2011, our institution changed the non-operative management (NOM) protocol of LSI from prolonged bed rest (PBR) to early mobilization (EM). We aim to show that EM safely decreases length of stay (LOS), ICU LOS, and cost. METHODS: We conducted a retrospective review in which non-operative LSI patients observed PBR from January 2008 through July 2011 and were mobilized early from August 2011 through December 2014. Endpoints assessed were length of bed rest, hospital LOS, ICU LOS, failure of NOM, cost, angiography/embolization, and mortality. RESULTS: There were a total of 184 patients with LSI who met study criteria and were not excluded. 77 patients utilized PBR between 2008 and 2011 and 107 followed EM protocol between 2011 and 2014. There was no significant difference in the male to female ratio, age, ISS, anticoagulant use, or MOI. Both groups had similar injury profiles. PBR included 34 liver injuries, 45 splenic injuries and two patients with both. EM included 63 liver injuries, 55 splenic injuries and 11 patients with both (for liver injury p = 0.053, for splenic injury p = 0.37, and for combined p = 0.08). LOS and cost were significantly decreased in the EM cohort. LOS was shortened by 1.07 days (p = 0.005) and cost of hospitalization was reduced by $7077 (p = 0.046). There was no difference in NOM failure, angiography/embolization, or mortality. CONCLUSION: EM in non-operative LSI is safe and cost-effective. It results in decreased LOS and cost without increasing failure of NOM, angiography, embolization, or mortality.

Nontrauma open abdomens: A prospective observational study.

BACKGROUND: Damage-control surgery with open abdomen (OA) is described for trauma, but little exists regarding use in the emergency general surgery. This study aimed to better define the following: demographics, indications for surgery and OA, fascial and surgical site complications, and in-hospital/long-term mortality. We hypothesize that older patients will have increased mortality, patients will have protracted stays, they will require specialized postdischarge care, and the indications for OA will be varied. METHODS: A prospective observational study of emergency general surgery OA patients from June 2013 to June 2014 was performed. Demographics, clinical/operative variables, comorbidities, indications for procedure and OA, wound/fascial complications, and disposition were collected. Patients were stratified into age groups (≤ 60, 61-79, and ≥ 80 years). Six-month and 1-year mortality was determined by query of the Social Security Death Index. RESULTS: A total of 338 laparotomies were performed, of which 96 (28%) were managed with an OA. Median age was 61 years (interquartile range [IQR], 0-68 years), and 51% were male. The median Charlson Comorbidity Index was 2 (IQR, 1.5-5.1), and the median hospital stay was 25 days (IQR, 15-50 days). The most common indications for operation were perforated viscus/free air (20%), mesenteric ischemia (17%), peritonitis (16%), and gastrointestinal hemorrhage (12%). The most common indication for OA was damage control (37%). In the 63 patients with fascial closure, there were 9 (14%) wound infections and 6 (10%) fascial dehiscences. A total of 30% of the patients died in the hospital, and an additional six patients died 6 months after discharge. Patients in the oldest age stratum were more likely to die at 6 months than those in the lower strata. CONCLUSION: Older patients were more likely to die by 6 months, the median hospital stay was 3 weeks, and there were multiple indications for OA management. With a 6-month mortality of 36% and 70% of survivors requiring postdischarge care, this population represents a critically ill population meriting additional study. LEVEL OF EVIDENCE: Prognostic and epidemiologic study, level III.

Decrease of morbidity in road traffic accidents in a high income country - an analysis of 24,405 accidents in a 21 year period.

BACKGROUND: The WHO initiated the "Decade of Action for Road Safety" because the fatality on road traffic accidents could become the fifth leading cause of death in 2030. On the contrary, fatalities continue to decrease in high income countries. The aim of the study was to find evidence for changes in injury severity of passenger car occupants after road traffic accidents in Germany over time, and to find contributing factors. METHODS: Data from the German In Depth Accident Study (GIDAS), representative for Germany, was used. A total of 24.405 accidents, reported from 1991 until 2011. 44.503 adult passenger car occupants were examined. A multivariable logistic regression model was developed to find reasons for observed trends over time. RESULTS: The relative decrease in mortality was 68.8% from 1991 until 2011. Between 2006 and 2011, the percentage of severely injured traffic victims was less than half, both in terms of the whole body and individual body regions. For injuries with an Abbreviated Injury Scale (AIS) ≥ 2, the percentage of persons with lower leg injuries declined by 72.5%, followed by the percentage of persons with pelvic injuries (61.5%), upper extremity injuries (57.7%), head injuries (54.3%), thorax injuries (50.0%), and abdomen injuries (40.0%). The multivariable regression model found 13 independent variables associated with injury prevention (e.g. seat belt use: OR 0.41, CI 95% 0.32-0.49; airbag: OR 0.86, CI 95% 0.75-0.99). The implementation of protective factors increased over time while accident constellations with a high probability for severe injury decreased over time. CONCLUSION: The decrease of severe injuries after road traffic accidents can be only attributed to a comprehensive approach including the enforcement of road safety policies and innovations in car engineering and emergency medicine. Traffic related measures and alcohol level control, and seat belt usage enforcement next to other technical advances are considered especially important.

Cell salvage in emergency trauma surgery.

BACKGROUND: Trauma is the leading cause of death in people under the age of 45 years. Over the past 20 years, intraoperative autologous transfusions (obtained by cell salvage, also known as intraoperative blood salvage (IBS)) have been used as an alternative to blood products from other individuals during surgery because of the risk of transfusion-related infections such as hepatitis and human immunodeficiency virus (HIV). In this review, we sought to assess the effects and cost of cell salvage in individuals undergoing abdominal or thoracic surgery. OBJECTIVES: To compare the effect and cost of cell salvage with those of standard care in individuals undergoing abdominal or thoracic trauma surgery. SEARCH METHODS: We ran the search on 25 November 2014. We searched the Cochrane Injuries Group's Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), Ovid MEDLINE, Ovid MEDLINE In-Process & Other Non-Indexed Citations, Ovid MEDLINE Daily and Ovid OLDMEDLINE, EMBASE Classic + EMBASE (OvidSP), PubMed, and ISI Web of Science (SCI-Expanded & CPSI-SSH). We also screened reference lists and contacted principal investigators. SELECTION CRITERIA: Randomised controlled trials comparing cell salvage with no cell salvage (standard care) in individuals undergoing abdominal or thoracic trauma surgery. DATA COLLECTION AND ANALYSIS: Two authors independently extracted data from the trial reports. We used the standard methodological procedures expected by The Cochrane Collaboration. MAIN RESULTS: Only one small study (n = 44) fulfilled the inclusion criteria. Results suggested that cell salvage did not affect mortality overall (death rates were 67% (14/21 participants) in the cell salvage group and 65% (15/23) in the control group) (odds ratio (OR) 1.07, 95% confidence interval (CI) 0.31 to 3.72). For individuals with abdominal injury, mortality was also similar in both groups (OR 0.48, 95% CI 0.11 to 2.10).Less donor blood was needed for transfusion within the first 24 hours postinjury in the cell salvage group compared with the control group (mean difference (MD) -4.70 units, 95% CI -8.09 to -1.31). Adverse events, notably postoperative sepsis, did not differ between groups (OR 0.54, 95% CI 0.11 to 2.55). Cost did not notably differ between groups (MD -177.81, 95% CI -452.85 to 97.23, measured in GBP in 2002). AUTHORS' CONCLUSIONS: Evidence for the use of cell salvage in individuals undergoing abdominal or thoracic trauma surgery remains equivocal. Large, multicentre, methodologically rigorous trials are needed to assess the relative efficacy, safety and cost-effectiveness of cell salvage in different surgical procedures in the emergency context.

A prospective observational study of abdominal injury management in contemporary military operations: damage control laparotomy is associated with high survivability and low rates of fecal diversion.

OBJECTIVE: This study describes the cause, management, and outcomes of abdominal injury in a mature deployed military trauma system, with particular focus on damage control, hollow visceral injury (HVI), and stoma utilization. BACKGROUND: Damage control laparotomy (DCL) is established in military and civilian practice. However, optimal management of HVI during military DCL remains controversial. METHODS: We studied abdominal trauma managed over 5 months at the Joint Force Combat Support Hospital, Camp Bastion, Afghanistan (Role 3). Data included demographics, wounding mechanism, injuries sustained, prehospital times, location of first laparotomy (Role 3 or forward), use of DCL or definitive laparotomy, subsequent surgical details, resource utilization, complications, and mortality. RESULTS: Ninety-four of 636 trauma patients (15%) underwent laparotomy. Military injury mechanisms dominated [44 gunshot wounds (47%), 44 blast (47%), and 6 blunt trauma (6%)]. Seventy-two of 94 patients (77%) underwent DCL. Four patients were palliated. Seventy of 94 (74%) sustained HVI; 44 of 70 (63%) had colonic injury. Repair or resection with anastomosis was performed in 59 of 67 therapeutically managed HVI patients (88%). Six patients were managed with fecal diversion, and 6 patients were evacuated with discontinuous bowel. Anastomotic leaks occurred in 4 of 56 HVI patients (7%) with known outcomes. Median New Injury Severity Score for DCL patients was 29 (interquartile range: 18-41) versus 19.5 (interquartile range: 12-34) for patients undergoing definitive laparotomy (P = 0.016). Overall mortality was 15 of 94 (16%). CONCLUSIONS: Damage control is now used routinely for battlefield abdominal trauma. In a well-practiced Combat Support Hospital, this strategy is associated with low mortality and infrequent fecal diversion.

Selective non operative management of gunshot wounds to the abdomen: a collective review.

BACKGROUND: Over the past four decades there has been a shift from operative to selective conservatism in trauma. Selective nonoperative management (SNOM) of stab wounds to the abdomen is widely accepted in trauma centres. However, selective conservatism with gunshot wounds to the abdomen is controversial. This collective review assesses the evidence of SNOM of gunshot wounds to the abdomen. METHODS: A Medline search between 1 January 1960 and 31 July 2013 was conducted identifying studies that investigated SNOM of gunshot wounds to the abdomen. Case reports, review articles and editorials were excluded. All other studies that investigated SNOM of gunshot wounds to the abdomen and its outcomes were included. RESULTS: A total of 37 studies were included of which 22 were prospective, 14 were retrospective and 1 case series. A total of 21330 patients with gunshot wounds to the abdomen were included, of which 6468 (30.3%) were managed nonoperatively. Successful SNOM was possible in 5510 (85.18%) patients and 958 (14.8%) failed SNOM and underwent delayed laparotomies. SNOM reduces rates of non-therapeutic laparotomies and the associated morbidity. Special aspects reviewed include the prehospital and nursing involvement in this modality of care. CONCLUSIONS: Current evidence supports SNOM of gunshot wounds to the abdomen. It is associated with a decreased rate of non therapeutic laparotomy. Careful patient selection and specially designed protocols should be established and adhered to.

Interhospital transfer of liver trauma in New Mexico: a state of austere resources.

BACKGROUND: There is debate in the trauma literature regarding the effect of prolonged prehospital transport on morbidity and mortality. This study analyzes the management of hepatic trauma patients requiring surgery and compares the outcomes of the group that was transferred to the University of New Mexico Hospital (UNMH) from outside institutions, to the directly admitted group. MATERIALS AND METHODS: The UNMH Trauma Database was queried from 2005-2012. Of 674 patients who sustained liver injuries, 163 required surgery: 46 patients (28.2%) underwent interhospital transfer, and 117 (71.8%) were directly admitted. Variables examined included transfer status, trauma mechanism, transport type, injury severity score (ISS), liver injury grade, and associated injuries. Outcome variables included length of stay (LOS) and 30-day mortality. Outcomes of the transfer group (TG) and direct admit group (DAG) were compared. RESULTS: Both TG and DAG had the same median age (31 y, P = 0.33). The blunt-to-penetrating ratio was the same for each group (48% blunt: 52% penetrating, P = 1.0). Median ISS was 25 for the TG and 26 for the DAG. Grade III or higher injury occurred in 29 (63%) of the TG and in 68 (58%) of the DAG (P = 0.56). Median hospital LOS was 14 d for TG and 9 d for DAG (P = 0.15). Median intensive care unit LOS was 4 d for both groups (P = 0.71). Thirty-day mortality was 20% in each group (P = 0.27). Using a multiple logistic regression model for the outcome of mortality, only age, ISS, and liver injury grade, not transfer status or transport type, had a significant effect on mortality. CONCLUSIONS: There was no significant difference in liver injury grade, ISS, LOS, and mortality between TG and DAG. In the patient population of our study, transfer status did not affect outcome.

Disparities in trauma: the impact of socioeconomic factors on outcomes following traumatic hollow viscus injury.

BACKGROUND: This piece aims to examine the relationships between hollow viscus injury (HVI) and socioeconomic factors in determining outcomes. HVI has well-defined injury patterns with complex postoperative convalescence and morbidity, representing an ideal focus for identifying potential disparities among a homogeneous injury population. MATERIALS AND METHODS: A retrospective review included patients admitted to a level I trauma center with HVI from 2000-2009, as identified in the Trauma Registry of the American College of Surgeons. Patients with concomitant significant solid organ or vasculature injury were excluded. US Census (2000) median household income by zip code was used as socioeconomic proxy. Demographic and injury-related variables were also included. Endpoints were mortality and outcomes associated with HVI morbidity. RESULTS: A total of 933 patients with HVI were identified and 256 met inclusion criteria. There were 23 deaths (9.0%), and mortality was not associated with race, gender, income, or payer source. However, lower median household income was significantly associated with longer intervals to ostomy takedown (P = 0.032). Additionally, private payers had significantly lower rates of anastomotic leak (0% [0/73] versus 7.1% [13/183], P = 0.019) and fascial dehiscence (5.5% [4/73] versus 16.9% [31/183], P = 0.016), while self-payers had significantly higher rates of abscess formation, both overall (24% [24/100] versus 10.2% [16/156], P = 0.004) and among penetrating injuries (27.4% [23/84] versus 13.6% [12/88], P = 0.036). CONCLUSIONS: Socioeconomic status may not impact overall mortality among trauma patients with hollow viscus injuries, but private insurance appears to be protective of morbidity related to anastomotic leak, fascial dehiscence, and abscess formation. This supports that socioeconomic disparity may exist within long-term outcomes, particularly regarding payer source.

[Evisceration of intestines following abdominal stab wounds: epidemiology and clinical aspects of emergency room management]. / Eviszeration von Darm nach Stichverletzung des Abdomens: Häufigkeit und klinische Aspekte des klinischen Schockraummanagements.

STUDY AIM: The aim of the study was an estimation of the incidence and clinical aspects of emergency room (ER) parameters of penetrating abdominal injury patients with bowel evisceration. STUDY DESIGN AND METHODS: The study involved a retrospective cohort analysis of ER data from the Chris Hani Baragwanath Academic Hospitals, Soweto, Johannesburg, South Africa between September 2000 to May 2005. RESULTS: Out of 9,010 ER patients, 4,390 suffered penetrating injuries with 8 out of 71 eviscerations due to a single gunshot wound, 60 out of 71 eviscerations due to single stab wounds and 3 further patients suffered multiple injuries. The ER mortality was 1 out of 71(1.6 %) with an average ER mortality of 4.2 %. The only death seen was a single abdominal gunshot wound with vascular injury. The causative mortality due to abdominal stab wounds with evisceration of the bowels was therefore zero. The heart rate in patients with abdominal stab wounds with and without bowel evisceration showed no significant difference, thus mesentery tearing or vagal overstimulation could not be seen, neither with bradycardia nor hypotension. CONCLUSION: Evisceration itself is not a cause for increased mortality or cardiovascular instability seen in the ER. There is ample time for diagnostic procedures before laparotomy is performed.

Predicting surgical exploration in renal trauma: assessment and modification of an established nomogram.

BACKGROUND: This study aimed to externally validate a previously described nomogram that predicts the need for renal exploration in the trauma setting. METHODS: The predicted probability of nephrectomy was manually calculated using prospectively collected data from consecutive patients with renal trauma who presented to our institution between May 2001 and January 2010. To assess nomogram performance, receiver operating characteristic curves against the observed exploration rate were generated, and areas under the curve were calculated. Calibration curves were generated to assess performance across the range of predicted probabilities. Logistic regression modeling was used to determine clinical factors predicting exploration in a contemporary setting, and a nomogram was derived and internally validated using bootstrapping. RESULTS: The established nomogram was applied to the 320 patients who presented during the 9-year period. The global performance of the established nomogram was very high, with an area under the curve of 0.95. However, the model performance was poor for higher predicted probabilities, thus lacking predictive ability in the population where the model has the greatest potential utility. A clinical tool was generated to better predict trauma nephrectomy in our contemporary population, using platelet transfusion within the first 24 hours, blood urea nitrogen, hemoglobin, and heart rate on admission. The global accuracy for the new model was similar to the previous nomogram, but it was significantly better calibrated for patients with higher probabilities of nephrectomy, with good predictive accuracy even in patients with Grade 5 injuries. CONCLUSION: Older nomogram fails to accurately predict renal exploration in high-grade injuries in the contemporary setting. A new nomogram that more accurately predicts the need for exploration is presented. LEVEL OF EVIDENCE: Therapeutic study, level IV; prognostic study, level III.

Early abdominal closure improves long-term outcomes after damage-control laparotomy.

BACKGROUND: The impact of initial clinical decisions on the long-term quality of life and functional outcome of patients who undergo damage-control laparotomy (DCL) is unknown. We hypothesized that early abdominal closure after DCL improves long-term outcomes. METHODS: Patients (2005-2011) who underwent DCL (n = 140) at our Level I trauma center were identified. A total of 108 patients survived their hospitalization, and 15 died following discharge. Of the remaining 93 survivors, 59 were unreachable and not present in the social security death index. Our final study population of 34 survivors prospectively completed a standardized study questionnaire, the SF-36 health survey, and inpatient and outpatient records were reviewed. Survivors were compared on the basis of time with final abdominal closure (early, <7 days vs. late, >7 days; either primary closure or Vicryl mesh), and study variables were analyzed. A p < 0.05 was considered significant. RESULTS: Our study population was primarily male (82%) of varying age (36 [13]) and mechanism (blunt 56%, penetrating 44%) with severe injuries (mean [SD] Injury Severity Score [ISS], 17 [8]). Despite no differences in age, sex, mechanism, ISS, admission Glasgow Coma Scale (GCS) score, or admission systolic blood pressure, early-closure patients (n = 13) had shorter hospital (25 days vs. 57 days) and intensive care unit (12 days vs. 20 days) stays and, upon long-term follow-up, higher physical (54 vs. 18), emotional (86 vs. 44), and general health (66 vs. 50) SF-36 scores than late-closure patients (n = 21) (all p < 0.05). Early-closure patients had less daily pain (38% vs. 95%), had higher overall SF-36 scores (66 vs. 46), and were more likely to return to work (54% vs. 10%) than late-closure patients (all p < 0.05). CONCLUSION: Early clinical decisions impact the lives of critically injured patients. Abdominal closure within 7 days of DCL improves long-term quality of life and functional outcome. LEVEL OF EVIDENCE: Therapeutic study, level IV.

[Objective assessment of trauma severity in patients with spleen injuries].

The work presents an analysis of condition severity of 139 casualties with isolated and combined spleen injuries on admission to a surgical hospital. The assessment of condition severity was made using the traditional gradation and score scale VPH-SP. The degree of the severity of combined trauma of the spleen was determined by the scales ISS. The investigation showed that the scale ISS and VPH-SP allowed objective measurement of the condition severity of patients with spleen trauma. The score assessment facilitated early detection of the severe category of the patients, determined the diagnostic algorithm and the well-timed medical aid.

National variation in outcomes and costs for splenic injury and the impact of trauma systems: a population-based cohort study.

OBJECTIVE: To measure national variation in splenectomy rates, mortality, and costs for hospitalized patients with splenic injury and the impact of state trauma systems on these outcomes. METHODS: Using the HCUP State Inpatient Database for 2001, 2004, and 2007, all patients hospitalized with splenic injury were identified from 19 participating states. Multivariate regression was performed to compare splenectomy rates, inpatient mortality, and costs between states. Inclusiveness of statewide trauma systems was categorized based on the proportion of hospitals designated as a trauma center. RESULTS: Of 33,131 patients, 26.2% underwent splenectomy, 6.1% died, and median hospital costs were $14,317. After adjusting for patient, injury, and hospital characteristics, there was a 1.7-fold variation (RR 1.67; 95% CI, 1.39-2.01) among the 19 states in rates of splenectomy. Adjusted inpatient mortality varied more than 2-fold between the highest and lowest states (RR 2.43; 95% CI, 1.76-3.37). Adjusted hospital costs varied over 60% between the highest and lowest states (cost ratio 1.61; 95% CI, 1.41-1.83). States with the most inclusive trauma systems had significantly lower splenectomy rate (RR 0.79; 95% CI, 0.68-0.92) and lower mortality (RR 0.71; 95% CI, 0.58-0.87), but similar hospital costs (CR 1.05; 95% CI, 0.95-1.16) compared to states with exclusive or no trauma systems. CONCLUSIONS: Significant geographic variation in the management, outcome, and costs for splenic injury exists in the United States, and may reflect differences in quality of care. Inclusive trauma systems seem to improve outcomes without increasing hospital costs.

[Application of standardized systems for assessment of prognosis of the traumatic process in patients with penetrating abdominal wounds and hepatic injuries].

There were examined 131 injured persons, suffering penetrating abdominal wounding and hepatic injury. Correlation analysis was done, basing on studying of the results of the injured persons state estimation, using prognostic scales, aiming to prognosticate the traumatic process course.

Assessment and outcome of 496 penetrating gastrointestinal warfare injuries.

AIM: The abdominal viscera are among the most vulnerable organs of the body to penetrating trauma. Proper management of such trauma in war victims at the first-line hospital where these victims are first seen is of paramount importance. We reviewed medical records of war victims suffering small bowel and colorectal injuries treated at first, second and third-line hospitals during the Iraq-Iran War (1980-88) to assess surgical outcomes. METHODS: The medical records of 496 Iranian war victims suffering penetrating gastrointestinal (GI) injuries treated at first, second and third-line (tertiary) hospitals, a total of 19 centres, were reviewed. Laparotomy had been performed at the 1st line hospitals for all patients who had an acute abdomen, whose wounds violated the peritoneum or whose abdominal radiographs showed air or shrapnel in the abdominal cavity. Stable patients were transferred from first-line to second-line or from second line to tertiary hospitals postoperatively. The treatments, complications and patient outcomes were documented and analyzed. RESULTS: There were 496 patients; 145, 220 and 131 victims underwent laparotomy for GI injuries at first, second and third-line hospitals respectively. The small intestine and colon respectively were the most prevalent abdominal organs damaged. Those first treated for GI injuries at front-line hospitals (145 victims) had more serious conditions and could not be transferred prior to surgery and presented a higher prevalence of complications and mortality. Overall mortality from GI surgery was 3.6% (18 patients). Eleven patients (7.5%) whose first GI operation was performed at frontline hospitals and 7 patients (3.2%) who underwent their first surgical operation at second-line hospitals died. The most common reason for these deaths was complications relating to the gastrointestinal operation such as anastomotic leak. Six missed injuries were seen at the frontline and one at second line hospitals. There were no deaths at the 3rd line hospitals. CONCLUSION: Penetrating abdominal injuries were common in Iranian victims of war often causing multiple organ injuries. The colon and small intestine were the more commonly injured organs and carried the most postoperative complications. Mortality at 1st line hospitals was more than double that of 2nd line hospitals; the complication rate was also greater as was the number of missed injuries. Adherence to the standard surgical protocols, prompt evaluation, proper triage and management are factors which may lower patient morbidity and complications.

Disparities in child abuse mortality are not explained by injury severity.

BACKGROUND: Unadjusted abuse-related mortality has been demonstrated to be nearly 4-fold higher for African American (AA) children. Little is known about the etiology of this disparity. This study examines the importance of injury severity and initial presentation in explaining the observed disparity. METHOD: Our trauma database was reviewed to identify all abused patients admitted over a 10-year period. Outcomes among white and AA children were compared with specific attention to injury severity scores and initial presentation. Logistic regression and Cox proportional hazard analyses were performed to evaluate the impact of race on outcome. RESULTS: There were 443 abused children identified. Thirty-eight percent of the group was AA. The overall mortality was 7.7%; however, the AA mortality was significantly higher than white children (14.8% vs 3.3%; P < .05). After controlling for injury severity and physiology at presentation, the odds ratio of mortality for an AA child was 9.14 (95% confidence interval, 1.97-42.43). Survival analysis confirmed the disparity after revealing a hazard ratio of dying for AA children of 6.51 (95% confidence interval, 2.74-15.47) compared with white children. CONCLUSION: Despite attempts to control for the clinical presentation and injury severity of abused children, significant differences in mortality persist between AA and white children.
