Abstract
BACKGROUND/PURPOSE The purposes of this study were to identify independent predictors of venous thromboembolism (VTE), to evaluate the relative impact of adult VTE risk factors, and to identify a pediatric population at high-risk for VTE after trauma. METHODS 1934 consecutive pediatric admissions (≤ 17 years) from 01/2000 to 12/2012 at a level 1 trauma center were reviewed. Logistic regression was used to identify predictors of VTE. RESULTS Twenty-two patients (1.2%) developed a VTE, including 5% of those requiring orthopedic surgery, 14% of those with major vascular injury (MVI), and 36% of those with both. Most (84%) were diagnosed at the primary site of injury. 86% of those who developed a VTE were receiving thromboprophylaxis at the time of diagnosis. Independent predictors were age (odds ratio (OR): 1.59, 95% confidence interval (CI): 1.11-2.25), orthopedic surgery (OR: 8.10, CI: 3.10-21.39), transfusion (OR: 3.37, CI: 1.26-8.99), and MVI (OR: 15.43, CI: 5.70-41.76). When known risk factors for VTE in adults were adjusted, significant factors were age ≥ 13 years (OR: 9.16, CI: 1.08-77.89), indwelling central venous catheter (OR: 4.41, CI: 1.31-14.82), orthopedic surgery (OR: 6.80, CI: 2.47-18.74), and MVI (OR: 14.41, CI: 4.60-45.13). CONCLUSION MVI and orthopedic surgery are synergistic predictors of pediatric VTE. Most children who developed a VTE were receiving thromboprophylaxis at the time of diagnosis.

Lost information during the handover of critically injured trauma patients: a mixed-methods study. BMJ Qual Saf 2015; 25:929-936. [PMID: 26545705 DOI: 10.1136/bmjqs-2014-003903] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2014] [Revised: 10/16/2015] [Accepted: 10/20/2015] [Indexed: 11/04/2022]
Abstract
BACKGROUND Clinical information may be lost during the transfer of critically injured trauma patients from the emergency department (ED) to the intensive care unit (ICU). The aim of this study was to investigate the causes and frequency of information discrepancies with handover and to explore solutions to improving information transfer. METHODS A mixed-methods research approach was used at our level I trauma centre. Information discrepancies between the ED and the ICU were measured using chart audits. Descriptive, parametric and non-parametric statistics were applied, as appropriate. Six focus groups of 46 ED and ICU nurses and nine individual interviews of trauma team leaders were conducted to explore solutions to improve information transfer using thematic analysis. RESULTS Chart audits demonstrated that injuries were missed in 24% of patients. Clinical information discrepancies occurred in 48% of patients. Patients with these discrepancies were more likely to have unknown medical histories (p<0.001) requiring information rescue (p<0.005). Close to one in three patients with information rescue had a change in clinical management (p<0.01). Participants identified challenges according to their disciplines, with some overlap. Physicians, in contrast to nurses, were perceived as less aware of interdisciplinary stress and their role regarding variability in handover. Standardising handover, increasing non-technical physician training and understanding unit cultures were proposed as solutions, with nurses as drivers of a culture of safety. CONCLUSION Trauma patient information was lost during handover from the ED to the ICU for multiple reasons. An interprofessional approach was proposed to improve handover through cross-unit familiarisation and use of communication tools is proposed. Going beyond traditional geographical and temporal boundaries was deemed important for improving patient safety during the ED to ICU handover.

Abstract
BACKGROUND Venous duplex ultrasound (VDU) is the modality of choice for surveillance of venous thromboembolism (VTE), but there is controversy about its appropriate implementation as a screening method. We hypothesize that VDU surveillance in trauma patients at high risk for VTE decreases the rate of pulmonary embolism (PE). STUDY DESIGN One thousand two hundred and eighty-two trauma ICU admissions were screened with Greenfield's Risk Assessment Profile from August 2011 to September 2014. Four hundred and two patients were identified as high risk for VTE (Risk Assessment Profile ≥10). Those who received weekly VDU to evaluate for deep vein thrombosis (n = 259 [64%]) were compared with those who did not (n = 143 [36%]). Parametric data are reported as mean ± SD and nonparametric data are reported as median (interquartile range). Statistical significance was determined at an α level of 0.05. RESULTS The overall study population was 47 ± 19 years old and 75% were male, 78% of injuries were blunt mechanism, Injury Severity Score was 28 ± 13, Risk Assessment Profile was 14 ± 4, and mortality was 14.3%. Deep vein thrombosis rate was 11.6% (n = 30) in the surveillance group vs 2.1% (n = 3) in the non-surveillance group (p < 0.001). Deep vein thromboses detected in the surveillance group were managed with systemic anticoagulation (43%) or with IVC filter placement (57%). In the surveillance group, the PE rate was 1.9% (n = 5) vs 7.0% (n = 10) in the non-surveillance group (p = 0.014). CONCLUSIONS Trauma patients at high risk for VTE and who received VDU surveillance and early management of deep vein thrombosis have decreased rates of pulmonary embolism.

Abstract
OBJECTIVES Other than automobiles, bicycles are connected to more pediatric injuries than any other consumer product. Whereas characterization of injury patterns following motor vehicle accidents has led to safety initiatives and treatment guidelines, knowledge related to bicyclist injuries is lacking. Our purpose is to identify major injury patterns and outcomes associated with pediatric bicycle accidents. METHODS From January 2000 to December 2012, 1934 consecutive pediatric admissions (≤17 years) at a level I trauma center were retrospectively reviewed for mechanism injury, demographics, and outcomes. Parametric data were analyzed with student's t test and are presented as mean ± standard deviation. Nonparametric data were analyzed with Mann-Whitney-U test and are presented as median (interquartile range). Analysis was performed to recognize injury patterns and outcomes significantly associated with bicycle related accidents. RESULTS 80 pediatric patients were admitted following bicycle related trauma (4% of all pediatric trauma admissions). The cohort was age 11 ± 4 years, ISS 11 ± 10, 48% black, and 81% male. Injury patterns included 21% isolated head, 21% isolated abdominal, 13% isolated extremity, and 34% multiple injuries. 5% were age 0-4 years, 35% were age 5-9 years, 45% were 10-14 years, and 15% were 15-17 years (p < 0.001). 16% required operative intervention (6% abdominal, 9% orthopedic, 1% vascular). Children under age 6 required an abdominal operation 20% of the time. Length of stay was 2 (4) days with a mortality of 2.5%. CONCLUSIONS Pediatric bicycle accidents more commonly occur in male children aged 10-14 years. Orthopedic injury is the most frequent overall indication for surgery, yet the youngest children more often required an abdominal operation. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Infection is the leading cause of death in burn patients. Historically, this was due to burn wound sepsis but pneumonia has now emerged as the most common source. In light of the increasing incidence of multi-drug-resistant organisms, the description of rare infections is paramount in continuing the fight against deadly pathogens. We aim to describe the second case of non-tuberculous mycobacterium (NTM) reported in a burn patient. Difficulties in diagnosis and management will also be highlighted. METHODS A 70-y-old Caucasian female, with a past medical history for type 2 diabetes mellitus, was transferred to our facility after a house fire. She had sustained a 28% total body surface area (TBSA) flame burn to her neck, torso, and all four extremities. She underwent excision and grafting on hospital day five with multiple subsequent attempts at excision and grafting due to graft loss. On hospital day 14, a tracheostomy was performed. Her hospital course was complicated by ongoing respiratory failure, renal injury, and sepsis. RESULTS Mycobacterium abscessus was found on blood cultures from central venous catheters and arterial line catheters as well as on tracheal aspirate and bronchoalveolar lavage (BAL) on hospital day 86. Imaging then revealed multiple pulmonary nodular densities with patchy ground-glass opacities. After multiple adjustments to the antibiotic regimen, tigecycline, clarithromycin, and cefoxitin therapy was started. She remained on this regimen for almost 4 wks. Her other infections included Acinetobacter baumanii treated with tobramycin and colistin, as well as Candida albicans for which she received fluconazole. Ultimately, her clinical state worsened leading to withdrawal of care. CONCLUSIONS Sepsis NTM is rare in burn patients with only one other case described in the English-language literature. Both cases reflect differences in diagnosis and management. This highlights the need to discuss rare infections in an attempt to broaden the clinician's awareness of such pathogens, as well as to collaborate to form a consensus about their management.

Abstract
We hypothesize there are coagulation profile changes associated both with initiation of thromboporphylaxis (TPX) and with change in platelet levels in trauma patients at high-risk for venous thromboembolism (VTE). A total of 1203 trauma intensive care unit patients were screened with a VTE risk assessment profile. In all, 302 high-risk patients (risk assessment profile score ≥ 10) were consented for weekly thromboelastography. TPX was initiated between initial and follow-up thromboelastography. Seventy-four patients were analyzed. Upon admission, 87 per cent were hypercoagulable, and 81 per cent remained hypercoagulable by Day 7 (P = 0.504). TPX was initiated 3.4 ± 1.4 days after admission; 68 per cent received unfractionated heparin and 32 per cent received low-molecular-weight heparin. The VTE rate was 18 per cent, length of stay 38 (25-37) days, and mortality of 17.6 per cent. In all, 76 per cent had a rapid clotting time at admission versus 39 per cent at Day 7 (P < 0.001); correcting from 7.75 (6.45-8.90) minutes to 10.45 (7.90-15.25) minutes (P < 0.001). At admission, 41 per cent had an elevated maximum clot formation (MCF) and 85 per cent had at Day 7 (P < 0.001); increasing from 61(55-65) mm to 75(69-80) mm (P < 0.001). Platelets positively correlated with MCF at admission (r = 0.308, R(2) = 0.095, P = 0.008) and at Day 7 (r = 0.516, R(2) = 0.266, P < 0.001). Change in platelet levels correlated with change in MCF (r = 0.332, R(2) = 0.110, P = 0.005). In conclusion, hypercoagulability persists despite the use of TPX. Although clotting time normalizes, MCF increases in correlation with platelet levels. As platelet function is a dominant contributor to sustained trauma-evoked hypercoagulability, antiplatelet therapy may be indicated in the management of severely injured trauma patients.

Abstract
BACKGROUND According to the 2002 Surgical Infection Society Guidelines on Antimicrobial Therapy for Intra-abdominal Infections, antimicrobial therapy is not recommended beyond 24 hours for the treatment of postoperative acute or gangrenous appendicitis without perforation. However, clinicians commonly consider gangrenous appendicitis to pose a greater risk of post-operative infectious complications, such as surgical site infections and intra-abdominal abscesses. This study examines the relative risk of post-operative infection between patients with simple and gangrenous appendicitis. METHODS A retrospective review of patients with either non-perforated gangrenous or simple appendicitis from 2010 to 2012 was performed at a large urban teaching hospital. RESULTS The rate of post-operative intra-abdominal abscess formation, which was diagnosed on patient readmission to the hospital, was significantly greater in patients with non-perforated gangrenous appendicitis in comparison to those with simple non-perforated appendicitis. Also, patients with non-perforated gangrenous appendicitis received extended courses of post-operative antibiotics, despite SIS recommendations. CONCLUSIONS The role of peri-operative antibiotics for non-perforated gangrenous appendicitis merits further study.

Abstract
BACKGROUND A massive transfusion protocol (MTP) presents a logistical challenge for most blood banks and trauma centers. We compare the ratio of packed red blood cells (PRBC) and plasma transfused over serial time points in those requiring MTP (10-30 U PRBC/24 h) to those requiring "super" MTP (S-MTP; >30 U PRBC/24 h) and test the hypothesis that changes in allocation of blood products with use of readily transfusable liquid plasma (LP) improves the ratio of PRBC and plasma during S-MTP. MATERIALS AND METHODS All transfused trauma patients (n = 1305) from January 01, 2009-April, 03, 2015 were reviewed. PRBC:plasma ratio was compared for MTP (n = 277) and S-MTP (n = 61) patients, before and after the availability of LP at our institution. Data are reported as mean ± standard deviation or median (interquartile range). RESULTS Age was 41 ± 19 y, 52% blunt mechanism, injury severity score 32 ± 16, and 46.3% mortality. In 24 h, requirements were 17 (14) U PRBC and 10 (11) U plasma, with a PRBC:plasma of 1.6 (0.8). Within the first hour, PRBC:plasma for S-MTP versus MTP was 2.1:1 versus 1.7:1 (P = 0.017). With LP, S-MTP patients received significantly lower PRBC:plasma at the first hour (P < 0.001). Before institutional changes, PRBC:plasma positively correlated with PRBC transfused at hour 1 (r = 0.410, R(2) = 0.168, P < 0.001); after institutional changes and the advent of LP, there was no correlation (r = 0.177, R(2) = 0.031, P = 0.219). CONCLUSIONS Within the first hour of transfusion, units of PRBC transfused positively correlated with PRBC:plasma, and patients receiving S-MTP had higher PRBC:plasma than those receiving MTP. Changes in our institution's MTP protocol to include LP improved the early PRBC:plasma transfused in patients requiring S-MTP.

Abstract
BACKGROUND The successful treatment of intraabdominal infection requires a combination of anatomical source control and antibiotics. The appropriate duration of antimicrobial therapy remains unclear. METHODS We randomly assigned 518 patients with complicated intraabdominal infection and adequate source control to receive antibiotics until 2 days after the resolution of fever, leukocytosis, and ileus, with a maximum of 10 days of therapy (control group), or to receive a fixed course of antibiotics (experimental group) for 4±1 calendar days. The primary outcome was a composite of surgical-site infection, recurrent intraabdominal infection, or death within 30 days after the index source-control procedure, according to treatment group. Secondary outcomes included the duration of therapy and rates of subsequent infections. RESULTS Surgical-site infection, recurrent intraabdominal infection, or death occurred in 56 of 257 patients in the experimental group (21.8%), as compared with 58 of 260 patients in the control group (22.3%) (absolute difference, -0.5 percentage point; 95% confidence interval [CI], -7.0 to 8.0; P=0.92). The median duration of antibiotic therapy was 4.0 days (interquartile range, 4.0 to 5.0) in the experimental group, as compared with 8.0 days (interquartile range, 5.0 to 10.0) in the control group (absolute difference, -4.0 days; 95% CI, -4.7 to -3.3; P<0.001). No significant between-group differences were found in the individual rates of the components of the primary outcome or in other secondary outcomes. CONCLUSIONS In patients with intraabdominal infections who had undergone an adequate source-control procedure, the outcomes after fixed-duration antibiotic therapy (approximately 4 days) were similar to those after a longer course of antibiotics (approximately 8 days) that extended until after the resolution of physiological abnormalities.

Abstract
BACKGROUND Obesity negatively affects outcomes after trauma and surgery; results after burns are more limited and controversial. The purpose of this study was to determine the effect of obesity on clinical and economic outcomes after thermal injury. METHODS The National Inpatient Sample was queried for adults from 2005-2009 with International Classification of Diseases-9 codes for burn injury. Demographics and clinical outcomes of obese and nonobese cohorts were compared. Univariate and multivariate analysis using logistic regression models were performed. Data are expressed as median (interquartile range) or mean ± standard deviation and compared at P < 0.05. RESULTS In 14,602 patients, 3.3% were obese (body mass index ≥30 kg/m(2)). The rate of obesity increased significantly by year (P < 0.001). Univariate analysis revealed significant differences between obese and nonobese patients in incidence of wound infection (7.2% versus 5.0%), urinary tract infection (7.2% versus 4.6%), deep vein thrombosis in total body surface area (TBSA) ≥10% (3.1% versus 1.1%), pulmonary embolism in TBSA ≥10% (2.3% versus 0.6%), length of stay [6 d (8) versus 5 d (9)], and hospital costs ($10,122.12 [$18,074.72] versus $7892.07 [$17,191.96]) (all P < 0.05). Death occurred less frequently in the obese group (1.9% versus 4%, P = 0.021). Significant predictors of grouped adverse events (urinary tract infection, wound infection, deep vein thrombosis, and pulmonary embolism) on multivariate analysis include obesity, TBSA ≥20%, age, and black race (all P ≤ 0.05). CONCLUSIONS Obesity is an independent predictor of adverse events after burn injury; however, obesity is associated with decreased mortality. Our findings highlight the potential clinical and economic impact of the obesity epidemic on burn patients nationwide.

Abstract
To our knowledge, this is the first comprehensive review on the subject of venous thromboembolism (VTE) and hypercoagulability in burn patients. Specific changes in coagulability are reviewed using data from thromboelastography and other techniques. Disseminated intravascular coagulation in burn patients is discussed. The incidence and risk factors associated with VTE in burn patients are then examined, followed by the use of low-molecular-weight heparin thromboprophylaxis and monitoring techniques using antifactor Xa levels. The need for large, prospective trials in burn patients is highlighted, especially in the areas of VTE incidence and safe, effective thromboprophylaxis.

Abstract
We aimed to determine the association between the presence ofAcinetobacter baumanniiin patient rooms and the carrier status of the occupants. Fifty-six (39%) of 143 rooms withA. baumannii– positive patients had results positive forA. baumannii.Only 49 (10%) of 485 rooms withA. baumannii-negative patients were positive (odds ratio, 5.72 [95% confidence interval, 3.66–8.96];P< .0001). Clinical and environmental isolates shared pulsed-field gel electrophoresis patterns.

Abstract
Objective.Potential transmission of organisms from the environment to patients is a concern, especially in enclosed settings, such as operating rooms, in which there are multiple and frequent contacts between patients, provider's hands, and environmental surfaces. Therefore, adequate disinfection of operating rooms is essential. We aimed to determine the change in both the thoroughness of environmental cleaning and the proportion of environmental surfaces within operating rooms from which pathogenic organisms were recovered.Design.Prospective environmental study using feedback with UV markers and environmental cultures.Setting.A 1,500-bed county teaching hospital.Participants.Environmental service personnel, hospital administration, and medical and nursing leadershipResults.The proportion of UV markers removed (cleaned) increased from 0.47 (284 of 600 markers; 95% confidence interval [CI], 0.42-0.53) at baseline to 0.82 (634 of 777 markers; 95% CI, 0.77-0.85) during the last month of observations (P < .0001). Nevertheless, the percentage of samples from which pathogenic organisms (gram-negative bacilli, Staphylococcus aureus, and Enterococcus species) were recovered did not change throughout our study. Pathogens were identified on 16.6% of surfaces at baseline and 12.5% of surfaces during the follow-up period (P = .998). However, the percentage of surfaces from which gram-negative bacilli were recovered decreased from 10.7% at baseline to 2.3% during the follow-up period (P = .015).Conclusions.Feedback using Gram staining of environmental cultures and UV markers was successful at improving the degree of cleaning in our operating rooms.

Abstract
Femoral vessel injuries are a familiar injury treated in busy urban trauma centers. The majority of peripheral vascular injuries to the lower extremity occur most commonly to the femoral vessels. The increasing incidence of civilian violence provides an opportunity to perform a comprehensive review and management of these injuries.

Abstract
BACKGROUND/PURPOSE The emergency department thoracotomy (EDT) is rarely utilized in children, and is thus difficult to identify survival factors. We reviewed our experience and performed a systematic review of reports of EDT in pediatric patients. METHODS Patients age ≤18 years who received an EDT from 1991 to 2012 at our institution and all published case series were reviewed. Data analyzed include age, sex, mechanism of injury (MOI), injury patterns, presence of vital signs (VS) or signs of life (SOL) in the field/ED, return of spontaneous circulation (ROSC), and survival. RESULTS A total of 252 patients were analyzed. 84% were male. 51% sustained penetrating injuries, and median age was 15 years. Upon arrival, 17% had VS, and 35% had SOL. After EDT, 30% experienced ROSC. The survival rate was 1.6% for blunt trauma, 10.2% for penetrating injuries, and 6.0% overall. CONCLUSION Survival of pediatric patients following EDT is comparable to recent analyses in adults. Children who sustain blunt injury and are without SOL have been uniformly unsalvageable. Children who sustain penetrating trauma and have SOL or are without SOL for a short time prior to arrival have been salvageable. There are no reported EDT survivors less than 14 years of age following blunt injury.
