The Effect of Alcohol Consumption on Geriatric Trauma Outcomes.

BACKGROUND: There is little consensus in the literature regarding the effect of ethanol intoxication on trauma outcomes. Data on its effect in the elderly are even sparser. Our aim was to better define the impact of alcohol use in the geriatric trauma population. MATERIALS AND METHODS: We conducted a retrospective review at a level I trauma center looking at admissions from January 2015 through December 2018. Patients were grouped by age: 15-64 y old (YOUNG) versus ≥ 65 y old (OLD). Blood alcohol content (BAC) ≤0.10 g/dL was ETOH (-), and BAC >0.10 g/dL was ETOH (+). These were then propensity matched by injury severity score and mechanism of injury. Fisher's exact test and linear regression were applied as appropriate. Significance was defined as P < 0.05. RESULTS: There were 8754 patients admitted during the study time frame. A total of 6106 patients were YOUNG and 2647 were OLD. A total of 146 (5.5%) OLD patients were ETOH (+), whereas 1488 (24.4%) YOUNG patients were ETOH (+) (P < 0.0001). To assess the impact of alcohol between the two age groups, 285 OLD patients were propensity matched with 285 YOUNG patients. Mortality was significantly higher in the OLD (11.9%) group than that in the YOUNG (3.5%) group (P < 0.001). Morbidity was also higher in OLD versus YOUNG patients overall (P < 0.05). The presence of ethanol did not significantly impact morbidity or mortality in YOUNG or OLD patients. CONCLUSIONS: Higher mortality and morbidity is unsurprising in geriatric trauma patients; however, alcohol does not appear to play a significant role in these outcomes.

Implementing and Evaluating SBIRT for Alcohol Use at a Level 1 Trauma Center: A Behavioral Medicine Approach.

To facilitate the early identification and treatment of alcohol misuse among trauma patients, the American College of Surgeons (ACS) requires ACS-accredited level 1 trauma centers to have an active alcohol screening and brief intervention program. The development, implementation, and evaluation of a screening, brief intervention, and referral to treatment as a new institutional standard of care for alcohol misuse at a level 1 trauma center is described. The Division of Behavioral Medicine, a health psychology-based service, was nominated to manage this initiative as a result of clinical training and expertise in assessment, evidence-based psychological interventions, and case management. Trauma patients with elevated blood alcohol concentrations were screened at the time of admission and several months post-hospitalization. Clinical data suggest that screening for alcohol misuse can help identify patients at risk for, and struggling with, alcohol use disorders, encourage positive changes in alcohol consumption patterns, and increase access to treatment. Recommendations for enhancing the effectiveness of this process, associated challenges and limitations, and considerations for future clinical and research endeavors are discussed.

Financial Impact of Minor Injury Transfers on a Level 1 Trauma Center.

BACKGROUND: Trauma centers frequently accept patients from other institutions who are being sent due to the need for a higher level of care. We hypothesized that patients with minor traumatic injuries who are transferred from outside institutions would impart a negative financial impact on the receiving trauma center. METHODS: We performed a retrospective review of all trauma patients admitted to our urban level I trauma center from October 1, 2011, through September 30, 2013. Patients were categorized as minor trauma if they did not require operation within 24 h of arrival, did not require ICU admission, did not die, and had a hospital length of stay <24 h. Transferred patients and nontransfers (those received directly from the field) were compared with respect to injury severity, insurance status, and hospital net margin. Student's t-test and z-test for proportions were performed for data analysis. RESULTS: A total of 6951 trauma patients were identified (transfer n = 2228, nontransfer n = 4724). Minor injury transfers (n = 440) were compared to nontransfers (n = 689). Hospital net margin of transferred patients and nontransferred patients were $2227 and $2569, respectively (P = 0.22). Percentages of uninsured/underinsured for transfers and nontransfers were 27.3% and 36.1%, respectively (P = 0.002). CONCLUSIONS: During our study period, 19.7% of transfers and 14.6% of nontransfers can be categorized as having minor trauma. Minor trauma transfer patients are associated with a positive hospital net margin for the trauma center that is similar to that of the nontransfer group. The data also demonstrate a lower percentage of uninsured/underinsured in the transferred group.

Outcomes of trauma victims with cardiac arrest who survive to intensive care unit admission.

BACKGROUND: The prognosis for patients with return of spontaneous circulation after trauma-related cardiac arrest (TRCA) is unclear. Our purpose was to (1) determine outcomes for patients with TRCA resuscitated and admitted to the intensive care unit (ICU), (2) identify ICU-based predictors of in-hospital death in this population, and (3) compare outcomes of patients resuscitated from TRCA and atraumatic cardiac arrest (ATCA). METHODS: We performed a cohort study using a registry of ICU admissions from 120 US hospitals from 2001 to 2005. Inclusion criteria were age >17 years, admission to ICU via the emergency department, and cardiopulmonary resuscitation preceding ICU arrival. The primary outcome measure was survival to hospital discharge. We compared TRCA and ATCA using binomial test and performed multivariable logistic regression to determine independent predictors of death among trauma subjects. RESULTS: A total of 4,048 subjects were included (309 TRCA and 3,739 nonTRCA). Forty percent of trauma subjects survived. Independent predictors of death among trauma subjects included persistent postresuscitation cardiovascular failure in the ICU and presentation to a nontrauma center. Despite being younger and having fewer comorbidities, subjects with TRCA had lower survival than subjects with ATCA (40% vs. 49%, p = 0.003). CONCLUSIONS: Despite lower survival than ATCAs, a significant percentage of TRCAs surviving to ICU admission were discharged alive. This suggests aggressive support of this population is not necessarily futile. Investigation into whether optimization of postresuscitation factors would improve outcome for these patients may be warranted.

Percutaneous versus open tracheostomy in the pediatric trauma population.

The purpose of this study was to determine the safety and efficacy of percutaneous versus open tracheostomy in the pediatric trauma population. A retrospective chart review was conducted of all tracheostomies performed on trauma patients younger than 18 years for an 8-year period. There was no difference in the incidence of brain, chest, or facial injury between the open and percutaneous tracheostomy groups. However, the open group had a significantly lower age (14.2 vs. 15.5 years; P < 0.01) and higher injury severity score (26 vs. 21; P = 0.015). Mean time from injury to tracheostomy was 9.1 days (range, 0 to 16 days) and was not different between the two methods. The majority of open tracheostomies were performed in the operating room and, of percutaneous tracheostomies, at the bedside. Concomitant feeding tube placement did not affect complication rates. There was not a significant difference between complication rates between the two methods of tracheostomy (percutaneous one of 29; open three of 20). Percutaneous tracheostomy can be safely performed in the injured older child.

Management of maxillofacial injuries with severe oronasal hemorrhage: a multicenter perspective.

BACKGROUND: Airway establishment and hemorrhage control may be difficult to achieve in patients with massive oronasal bleeding from maxillofacial injuries. This study was formulated to develop effective algorithms for managing these challenging injuries. METHODS: Trauma registries from nine trauma centers were queried over a 7-year period for injuries with abbreviated injury scale face >/= 3 and transfusion of >/=3 units of blood within 24 hours. Patients in whom no significant bleeding was attributed to maxillofacial trauma were excluded. Patient demographics, injury severity measures, airway management, hemostatic procedures, and outcome were analyzed. RESULTS: Ninety patients were identified. Median injury severity scores for 60 blunt trauma patients was 34 versus 17 for 30 patients with penetrating wounds (p < 0.05). Initial airway management was by endotracheal intubation in 72 (80%) patients. Emergent cricothyrotomy and tracheostomy were necessary in 7 (8%) and 5 (6%) patients, respectively. Seventeen (57%) patients with penetrating wounds were taken directly to the operating room for airway control and initial efforts at hemostasis versus 12 (20%) patients with blunt trauma (p < 0.05). Anterior or posterior or both packing alone controlled bleeding in only 29% of patients in whom it was used. Transarterial embolization (TAE) was used in 12 (40%) patients with penetrating injuries and 20 (33%) patients with blunt trauma. TAE was successful for definitive control of hemorrhage in 87.5% of patients. Overall mortality rate was 24.4%, with 6 (7%) deaths directly attributable to maxillofacial injuries. CONCLUSIONS: Initial airway control was achieved by endotracheal intubation in most patients. Patients with penetrating wounds were more frequently taken directly to the operating room for airway management and initial efforts at hemostasis. Patients with blunt trauma were much more likely to have associated injuries which affected treatment priorities. TAE was highly successful in controlling hemorrhage.

Delayed primary closure in damage control laparotomy: the value of the Wittmann patch.

Damage control laparotomy has become an accepted practice in trauma surgery. A number of methods leading to delayed primary closure of the abdomen have been advocated; complications are recognized with all these methods. The approach to staged repair using the Wittmann patch (Star Surgical Inc., Burlington, WI) combines the advantages of planned relaparotomy and open management, while minimizing the rate of complications. The authors hypothesized that use of the Wittmann patch would lead to a high rate of delayed primary closure of the abdomen. The patch consists of two sheets sutured to the abdominal fascia, providing for temporary closure. Advancement of the patch and abdominal exploration can be done at bedside. When the fascial edges can be reapproximated without tension, abdominal closure is performed. Twenty-six patients underwent staged abdominal closure during the study period. All were initially managed with intravenous bag closure. Eighty-three per cent (20 of 24) went on to delayed primary closure of the abdomen, with a mean time of 13.1 days from patch placement to delayed primary closure. The rate of closure using the Wittmann patch is equivalent to other commonly used methods and should be considered when managing patients with abdominal compartment syndrome or severe abdominal trauma.

Nonoperative management of epidural hematomas and subdural hematomas: is it safe in lesions measuring one centimeter or less?

BACKGROUND: Management of a patient with a closed head injury is based on neurologic status and computerized tomography scan results. We hypothesized that those patients with an epidural hematoma (EDH) or subdural hematoma (SDH) <1 cm in thickness could safely be treated nonoperatively. METHODS: We retrospectively reviewed charts of 204 consecutive patients with either an EDH or SDH. RESULTS: There were 122 lesions < or =1 cm and 82 lesions >1 cm. In the first group, 115 were managed nonoperatively, with 111 good outcomes (minimal deficit with a Rancho Los Amigos score [RLAS] > or =3), two poor outcomes (severely disabled with RLAS <3), and two deaths. Twenty-eight patients with lesions greater than 1 cm had concomitant cerebral edema (CE) with an 89% mortality rate. The mortality rate in this group without CE was 20%, demonstrating the presence of CE in this group may have adversely affected the mortality rate, regardless of intervention. CONCLUSIONS: This data suggests that EDH or SDH <1 cm thick can be safely managed nonoperatively unless there is concomitant CE.

Caring for critically injured children: An analysis of 56 pediatric damage control laparotomies.

BACKGROUND: Injury is the leading cause of death in children under 18 years. Damage control principles have been extensively studied in adults but remain relatively unstudied in children. Our primary study objective was to evaluate the use of damage control laparotomy (DCL) in critically injured children. METHODS: An American College of Surgeons-verified Level 1 trauma center review (1996-2013) of pediatric trauma laparotomies was undertaken. Exclusion criteria included: age older than 18 years, laparotomy for abdominal compartment syndrome or delayed longer than 2 hours after admission. Demographics, mechanism, resuscitation variables, injuries, need for DCL, and outcomes were evaluated. Independent t test, Mann-Whitney U test, Fisher's exact test, and single-factor analysis of variance assessed statistical significance. Study endpoints were hospital survival and DCL complications. RESULTS: Of 371 children who underwent trauma laparotomy, the median age (IQR; LQ-UQ) age was 16 (5; 11-17) years. Most (73%) were male injured by blunt mechanism (65%). Fifty-six (15%) children (Injury Severity Score [ISS], 33 (25; 17-42), pediatric trauma score 5 (6; 2-8), penetrating abdominal trauma index score [PATI] 29 (32; 12-44)) underwent DCL after major solid organ (63%), vascular (36%), thoracic (38%) and pelvic (36%) injury. DCL patients were older (16.5 (4; 14-18) vs. 16 (7; 10-17)) and were more severely injured (ISS, 33 [25; 17-42] vs. 16 [16; 9-25]), requiring greater intraoperative packed red blood cell transfusion (8 [13; 3.5-16.5] vs. 1 (0; [0-1] units) than definitive laparotomy counterparts. Nonsurvivors arrived in severe physiologic compromise (base deficit, 17 [17; 8-25] vs. 7 [4; 4-8]), requiring more frequent preoperative blood product transfusion (67% vs. 10%) after comparable injury (ISS survivors, 36 [23; 18-41] vs. nonsurvivors 26 (7; 25-32), p = 0.8880). Fifty-five percent of DCL patients survived (length of stay, 26 [21; 18-39] days) requiring 3 (2; 2-4) laparotomies during 4 (6; 2-8) days until closure (fascial, 90%; vicryl/split thickness skin grafting, 10%). DCL complications (surgical site infection, 18%; dehiscence, 2%; enterocutaneous fistula, 2%) were analyzed. When stratified by age (<15 years vs. 15-18 years) and period (1996-2006 vs. 2007-2013), no differences were found in injury severity or DCL outcomes (p > 0.05). After controlling for DCL, age, and gender, multivariate analysis indicated only ISS (odds ratio, 1.10 [95% confidence interval, 1.01 - 1.19], p = 0.0218) and arrival systolic blood pressure (odds ratio, 0.96 [95% confidence interval, 0.93-0.99], p = 0.0254) predicted mortality after severe injury. CONCLUSION: DCL is a proven, lifesaving surgical technique in adults. This report is the first to analyze the use of DCL in children with critical abdominal injuries. With similar survival and morbidity rates as critically injured adults, DCL merits careful consideration in children with critical abdominal injuries. LEVEL OF EVIDENCE: Therapeutic study, level IV.

Care of critically ill surgical patients using the 80-hour Accreditation Council of Graduate Medical Education work-week guidelines: a survey of current strategies.

As a result of the recently mandated work-hour restrictions, it has become more difficult to provide 24-hour intensive care unit (ICU) in-house coverage by the general surgical residents. To assess the current state of providing appropriate continuous care to surgical critical care patients during the era of resident work-hour constraints, a national survey was conducted by the Association of Program Directors of Surgery. The results revealed that 37 per cent of programs surveyed have residents other than general surgery housestaff providing cross-coverage and writing orders for surgical ICU patients. Residents in emergency medicine, anesthesia, family medicine, otorhinolaryngology, obstetrics/gynecology, internal medicine, urology, and orthopedic surgery have provided this cross-coverage. Some found it necessary to use physician extenders (i.e., nurse practitioners or physician assistants), thereby decreasing the burden of surgical housestaff coverage. The results indicated that 30 per cent use physician extenders to help cover the ICU during daytime hours and 11 per cent used them during nighttime hours. In addition, 24 per cent used a "night-float" system in an attempt to maintain continuous care, yet still adhere to the mandated guidelines. In conclusion, our survey found multiple strategies, including the use of physician extenders, a "night-float" system, and the use of nongeneral surgical residents in an attempt to provide continuous coverage for surgical ICU patients. The overall outcome of these new strategies still needs to be assessed before any beneficial results can be demonstrated.

Multicenter validation of American Association for the Surgery of Trauma grading system for acute colonic diverticulitis and its use for emergency general surgery quality improvement program.

BACKGROUND: The American Association for the Surgery of Trauma (AAST) has developed a new grading system for uniform description of anatomic severity of emergency general surgery (EGS) diseases, ranging from Grade I (mild) to Grade V (severe). The purpose of this study was to determine the relationship of AAST grades for acute colonic diverticulitis with patient outcomes. A secondary purpose was to propose an EGS quality improvement program using risk-adjusted center outcomes, similar to National Surgical Quality Improvement Program and Trauma Quality Improvement Program methodologies. METHODS: This was a retrospective study of 1,105 patients (one death) from 13 centers. At each center, two reviewers (blinded to each other's assignments) assigned AAST grades. Interrater reliability was measured using κ coefficient. Relationship between AAST grade and clinical events (complications, intensive care unit use, surgical intervention, and 30-day readmission) as well as length of stay was measured using regression analyses to control for age, comorbidities, and physiologic status at the time of admission. Final model was also used to calculate observed-to-expected (O-E) ratios for adverse outcomes (death, complications, readmissions) for each center. RESULTS: Median age was 54 years, 52% were males, 43% were minorities, and 22% required a surgical intervention. Almost two thirds had Grade I or II disease. There was a high level of agreement for grades between reviewers (κ = 0.81). Adverse events increased from 13% for Grade I, to 18% for Grade II, 28% for Grade III, 44% for Grade IV, and 50% for Grade V. Regression analysis showed that higher disease grades were independently associated with all clinical events and length of stay, after adjusting for age, comorbidities, and physiology. O-E ratios showed statistically insignificant variations in risk of death, complications, or readmissions. CONCLUSION: AAST grades for acute colonic diverticulitis are independently associated with clinical outcomes and resource use. EGS quality improvement program methodology that incorporates AAST grade, age, comorbidities, and physiologic status may be used for measuring quality of EGS care. High-quality EGS registries are essential for developing meaningful quality metrics. LEVEL OF EVIDENCE: Prognostic study, level V.

The impact of a multidisciplinary safety checklist on adverse procedural events during bedside bronchoscopy-guided percutaneous tracheostomy.

BACKGROUND: Bedside procedures are seldom subject to the same safety precautions as operating room (OR) procedures. Since July 2013, we have performed a multidisciplinary checklist before all bedside bronchoscopy-guided percutaneous tracheostomy insertions (BPTIs). We hypothesized that the implementation of this checklist before BPTI would decrease adverse procedural events. METHODS: A prospective study of all patients who underwent BPTI after checklist implementation (PostCL, 2013-2014, n = 63) at our Level I trauma center were compared to all patients (retrospectively reviewed historical controls) who underwent BPTI without the checklist (PreCL, 2010-2013, n = 184). Exclusion criteria included age less than 16 years, OR, and open tracheostomy. The checklist included both a procedural and timeout component with the trauma technician, respiratory therapist, nurse, and surgeon. Demographics and variables focusing on BPTI risk factors were compared. Variables associated with the primary end point, adverse procedural events, during univariate analysis were used in the multiple variable logistic regression model. A p ≤ 0.05 was significant. RESULTS: Of 247 study sample patients, no difference existed in body mass index, baseline mean arterial pressure, duration or mode of mechanical ventilation, cervical spine or maxillofacial injury, or previous neck surgery between PreCL and PostCL BPTI patients. PreCL patients were younger (48 [20] years vs. 57 [21] years, p < 0.01) but more often had adverse procedural events compared with PostCL patients (PreCL,14.1% vs. PostCL,3.2%, p = 0.020). After adjusting for age, vitals, BPTI risk factors, and intensive care unit duration after BPTI, multiple variable logistic regression determined that performing the safety checklist alone was independently associated with a 580% reduction in adverse procedural events (odds ratio, 5.8; p = 0.022). CONCLUSION: Our results suggest that the implementation of a multidisciplinary safety checklist similar to those used in the OR would benefit patients during invasive bedside procedures. LEVEL OF EVIDENCE: Therapeutic/care management study, level IV.

ICD-9-CM and ICD-10-CM mapping of the AAST Emergency General Surgery disease severity grading systems: Conceptual approach, limitations, and recommendations for the future.

The American Association for the Surgery of Trauma (AAST) recently established a grading system for uniform reporting of anatomic severity of several emergency general surgery (EGS) diseases. There are five grades of severity for each disease, ranging from I (lowest severity) to V (highest severity). However, the grading process requires manual chart review. We sought to evaluate whether International Classification of Diseases, 9th and 10th Revisions, Clinical Modification (ICD-9-CM, ICD-10-CM) codes might allow estimation of AAST grades for EGS diseases. The Patient Assessment and Outcomes Committee of the AAST reviewed all available ICD-9-CM and ICD-10-CM diagnosis codes relevant to 16 EGS diseases with available AAST grades. We then matched grades for each EGS disease with one or more ICD codes. We used the Official Coding Guidelines for ICD-9-CM and ICD-10-CM and the American Hospital Association's "Coding Clinic for ICD-9-CM" for coding guidance. The ICD codes did not allow for matching all five AAST grades of severity for each of the 16 diseases. With ICD-9-CM, six diseases mapped into four categories of severity (instead of five), another six diseases into three categories of severity, and four diseases into only two categories of severity. With ICD-10-CM, five diseases mapped into four categories of severity, seven diseases into three categories, and four diseases into two categories. Two diseases mapped into discontinuous categories of grades (two in ICD-9-CM and one in ICD-10-CM). Although resolution is limited, ICD-9-CM and ICD-10-CM diagnosis codes might have some utility in roughly approximating the severity of the AAST grades in the absence of more precise information. These ICD mappings should be validated and refined before widespread use to characterize EGS disease severity. In the long-term, it may be desirable to develop alternatives to ICD-9-CM and ICD-10-CM codes for routine collection of disease severity characteristics.

Comparison of atriocaval shunting with perihepatic packing versus perihepatic packing alone for retrohepatic vena cava injuries in a swine model.

BACKGROUND: Retrohepatic vena cava (RVC) injuries are technically challenging and often lethal. Atriocaval shunting has been promoted as a modality to control haemorrhage from these injuries, but evidence from controlled studies supporting its benefit is lacking. We hypothesised that addition of an atriocaval shunt to perihepatic packing would improve outcomes in our penetrating RVC injury swine model. METHODS: After a survivable atriocaval shunting model was refined in 4 swine without an injury, 13 additional female Yorkshire swine were randomised into either perihepatic packing and atriocaval shunt (PPAS, n=7) or perihepatic packing alone (PP, n=6) treatment arms prior to creating a standardised, 1.5 cm stab wound to the RVC. Haemodynamic parameters, intravenous fluid, and blood loss were recorded until mortality or euthanisation after 4h. Statistical tests used to test differences include the Wilcoxon rank sums test, Fisher exact test and analysis of covariance. A p-value ≤0.05 was considered statistically significant. RESULTS: Immediately before and after RVC injury, no difference in temperature, cardiac output, heart rate, mean arterial pressure or mean pulmonary artery pressure was detected (all p>0.05) between the two groups. While the RVC injury did affect measures parameters in PPAS swine over time, haemodynamic compromise and blood loss were not significantly greater in PPAS than PP swine. Survival time was significantly different with all PPAS swine dying within 2h (mean survival duration 39 (SD 58)min) while all 6 PP swine survived the entire 4h study period. CONCLUSIONS: While perihepatic packing alone slowed haemorrhage to survivable rates during the 4h study period, atriocaval shunt placement led to rapid physiologic decline and death in our standardised, penetrating RVC model.

Ultrasound is not a useful screening tool for acute acalculous cholecystitis in critically ill trauma patients.

Acute acalculous cholecystitis remains a diagnostic challenge in critically ill trauma patients. Laboratory studies are nonspecific and associated injuries or mental status changes may mask clinical signs and symptoms. We conducted a retrospective study to assess the utility of ultrasound in the diagnosis of acute acalculous cholecystitis. We hypothesized that ultrasound is inadequate as a screening tool for acute acalculous cholecystitis. The abdominal ultrasounds of all patients undergoing evaluation for acute acalculous cholecystitis in a 40-month period at our Level I trauma center were reviewed. Thickened gallbladder wall, pericholecystic fluid and emphysematous gallbladder were considered positive sonographic criteria. Sludge, cholelithiasis, and hydrops were considered suggestive. Patients who did not undergo cholecystectomy had their gallbladders evaluated either during subsequent laparotomy or at autopsy or they were discharged from the hospital without need for intervention. Sixty-two patients were included. Twenty-one patients underwent cholecystectomy for presumed acute acalculous cholecystitis. The data revealed a sensitivity of 30 per cent (6/20) and a specificity of 93 per cent (39/42) for ultrasound evaluation. Twenty patients had subsequent hepatobiliary scans [hepato-iminodiacetic acid (HIDA)] with a sensitivity of 100 per cent (12/12) and specificity of 88 per cent (7/8). Our data do not support ultrasound as a reliable routine screening tool for acute acalculous cholecystitis. Despite its convenience as a bedside procedure ultrasound has insufficient sensitivity to justify its use and a more sensitive diagnostic tool should be used.

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.

Skin closure after trauma laparotomy in high-risk patients: opening opportunities for improvement.

BACKGROUND: Although many surgeons leave laparotomy incisions open after colon injury to prevent surgical site infection (SSI), other injured patient subsets are also at risk. We hypothesized that leaving trauma laparotomy skin incisions open in high-risk patients with any enteric injury or requiring damage control laparotomy (DCL) would not affect superficial SSI and fascial dehiscence rates. METHODS: Patients who underwent trauma laparotomy (2004-2008) at two Level I centers were reviewed. To ensure a high-risk sample, only patients with transmural enteric injuries or need for DCL surviving 5 days or more were included. SSIs were categorized by the CDC (Centers for Disease Control and Prevention) criteria and risk factors were analyzed by skin closure (open vs. any closure). Significant (p < 0.05) univariate variables were applied to two multivariate analyses examining superficial SSI and fascial dehiscence. RESULTS: Of 1,501 patients who underwent laparotomy, 503 met inclusion criteria. Patients were young (median, 28.0 years; range, 22.0-40.0 years) with penetrating (74%) or enteric (80%) injuries, and DCL (36%) and SSI (44%; superficial, 25%; deep, 3%; organ/space, 25%) were common. While no difference in superficial SSI after loose (n = 136) or complete skin closure (n = 224) was detected (p = 0.64), superficial SSIs were less common with open skin incisions (9.8%), despite multiple risk factors, than with any skin closure (31.1%, p < 0.001). Predictors of superficial SSIs and fascial dehiscence were each evaluated with multiple-variable logistic regression analysis. After adjusting for multiple potential confounding variables, any skin closure increased the risk of superficial SSIs approximately nine times (odds ratio, 8.6; p < 0.001) and fascial dehiscence six times (odds ratio, 5.7; p = 0.013). CONCLUSION: Management of skin incisions takes careful consideration like any other step of a laparotomy. Our results suggest that the decision to leave skin open is one simple method to improve outcomes in high-risk patients. LEVEL OF EVIDENCE: Therapeutic study, level III.

"SCIP"ping antibiotic prophylaxis guidelines in trauma: The consequences of noncompliance.

OBJECTIVE: The Surgical Care Improvement Project (SCIP) established surgical antibiotic prophylaxis guidelines as part of a national patient safety initiative aimed at reducing surgical complications such as surgical site infection (SSI). Although these antibiotic prophylaxis guidelines have become well established in surgical patients, they remain largely unstudied in patients with injury from trauma undergoing operative procedures. We sought to determine the role of these antibiotic prophylaxis guidelines in preventing SSI in patients undergoing trauma laparotomy. METHODS: A retrospective review of all patients who underwent emergency trauma laparotomy at two Level I trauma centers (2007-2008) revealed 306 patients who survived more than 4 days after injury. Demographics and clinical risk SSI factors were analyzed, and patients were compared on the basis of adherence to the following SCIP guidelines: (1) prophylactic antibiotic given, (2) antibiotic received within 1 hour before incision, (3) correct antibiotic selection, and (4) discontinuation of antibiotic within 24 hours after surgery. The primary study end point was the development of SSI. RESULTS: The study sample varied by age (mean [SD], 32 [16] years) and injury mechanism (gunshot wound 44%, stab wound 27%, blunt trauma 30%). When patients with perioperative antibiotic management complying with the four SCIP antibiotic guidelines (n = 151) were compared with those who did not comply (n = 155), no difference between age, shock, small bowel or colon resection, damage control procedures, and skin closure was detected (p > 0.05). After controlling for injury severity score, hypotension, blood transfusion, enteric injury, operative duration, and other potential confounding variables in a multivariate analysis, complete adherence to these four SCIP antibiotic guidelines independently decreased the risk of SSI (odds ratio, 0.43; 95% confidence interval, 0.20-0.94; p = 0.035). Patients adhering to these guidelines less often developed SSI (17% vs. 33%, p = 0.001) and had shorter overall hospital duration of antibiotics (4 [6] vs. 9 [11] days, p < 0.001) and hospital length of stay (14 [13] vs. 19 [23] days, p = 0.016), although no difference in mortality was detected (p > 0.05). CONCLUSIONS: Our results suggest that SCIP antibiotic prophylaxis guidelines effectively reduce the risk of SSI in patients undergoing trauma laparotomy. Despite the emergent nature of operative procedures for trauma, efforts to adhere to these antibiotic guidelines should be maintained.

The use of emergency department thoracotomy for traumatic cardiopulmonary arrest.

Despite the establishment of evidence-based guidelines for the resuscitation of critically injured patients who have sustained cardiopulmonary arrest, rapid decisions regarding patient salvageability in these situations remain difficult even for experienced physicians. Regardless, survival is limited after traumatic cardiopulmonary arrest. One applicable, well-described resuscitative technique is the emergency department thoracotomy-a procedure that, when applied correctly, is effective in saving small but significant numbers of critically injured patients. By understanding the indications, technical details, and predictors of survival along with the inherent risks and costs of emergency department thoracotomy, the physician is better equipped to make rapid futile versus salvageable decisions for this most severely injured subset of patients.

Is low-molecular-weight heparin safe for venous thromboembolism prophylaxis in patients with traumatic brain injury? A Western Trauma Association multicenter study.

BACKGROUND: Venous thromboembolism (VTE) is a significant risk in trauma patients. Although low-molecular weight heparin (LMWH) is effective in VTE prophylaxis, its use for patients with traumatic intracranial hemorrhage remains controversial. The purpose of this study was to evaluate the safety of LMWH for VTE prophylaxis in blunt intracranial injury. METHODS: We conducted a retrospective multicenter study of LMWH chemoprophylaxis on patients with intracranial hemorrhage caused by blunt trauma. Patients with brain Abbreviated Injury Scale score of 3 or higher, age 18 years or older, and at least one repeated head computed tomographic scan were included. Patients with previous VTE; on preinjury anticoagulation; hospitalized for less than 48 hours; on heparin for VTE prophylaxis; or required emergent thoracic, abdominal, or vascular surgery at admission were excluded. Patients were divided into two groups: those who received LMWH and those who did not. The primary outcome was progression of intracranial hemorrhage on repeated head computed tomographic scan. RESULTS: The study included 1,215 patients, of which 220 patients (18.1%) received LMWH and 995 (81.9%) did not. Hemorrhage progression occurred in 239 of 995 control subjects and 93 of 220 LMWH patients (24% vs. 42%, p < 0.001). Hemorrhage progression occurred in 32 patients after initiating LMWH (14.5%). Nine of these patients (4.1%) required neurosurgical intervention for hemorrhage progression. CONCLUSION: Patients receiving LMWH were at higher risk for hemorrhage progression. We were unable to demonstrate safety of LMWH for VTE prophylaxis in patients with brain injury. The risk of using LMWH may exceed its benefit. LEVEL OF EVIDENCE: Therapeutic study, level IV.
