Abstract
Background: Perioperative antibiotic prophylaxis is perceived to reduce intraoperative bacteraemia and prevent surgical site infections, however, the evidence for its use in burns surgery is limited. Excessive use of perioperative antibiotics has become a growing concern. The authors aimed to audit the prescribing practices of perioperative antibiotic prophylaxis at the Victorian Adult Burns Service and determine whether the duration of antibiotic prophylaxis influenced the risk of postoperative wound infection, bacte-raemia and antibiotic resistance.
Methods: This retrospective chart review included all acute adult burns patients who had an operation between November 2018 and November 2019. Basic demographic data, burn specific data and data on perioperative antibiotic use were collected. The outcome measures were wound infection, bacteraemia, other infections and presence of resistant organisms.
Results: Results demonstrated that almost all patients (98.6%) received perioperative antibiotic prophylax-is. In comparison, there was no significant difference between the rate of postoperative wound infection, bacteraemia or antibiotic resistance between patients receiving a short or long course of antibiotics.
Conclusion: The results of our study demonstrate variable use of perioperative antibiotic prophylaxis with-in one burns unit. There were many cases of unsubstantiated use of long courses of antibiotics without apparent benefit for clinical outcomes of wound infection or bacteraemia. With the growing concern over antibiotic overuse and development of resistance, there is an increasing need for development of clear guidelines for antibiotic use in burns surgery.

Antibiotic use among surgical inpatients at a tertiary health facility: a case for a standardized protocol for presumptive antimicrobial therapy in the developing world. Infect Prev Pract 2020; 2:100078. [PMID: 34368721 PMCID: PMC8336176 DOI: 10.1016/j.infpip.2020.100078] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2020] [Accepted: 07/17/2020] [Indexed: 11/28/2022] Open
Abstract
Background Indiscriminate antimicrobial use is one of the greatest contributors to antimicrobial resistance. A low level of asepsis in hospitals and inadequate laboratory support have been adduced as reasons for indiscriminate use of antimicrobials among surgical patients. At present, there are no guidelines for presumptive antibiotic use in Nigeria and sub-Saharan Africa. Aim Surgical inpatients at the study hospital were surveyed to determine the level of antimicrobial use and degree of compliance with prescription quality indicators. Methods A cross-sectional survey was conducted among all surgical inpatients in May 2019 using a standardized tool developed by the University of Antwerp to assess the point prevalence of antimicrobials. Inpatients who were admitted from 08:00 h on the day of the survey were included. Data on patients' demographics, indication for antimicrobial use, reason for antimicrobial use, stop/review date, adherence to guidelines and laboratory use were collected. The prevalence of antimicrobial use in the surgical department was estimated. Results Eighty-two inpatients were included in the survey. Of these, 97.6% were receiving at least one antimicrobial agent. Only 5.4% of the prescriptions were targeted, and 37.6% of prescriptions were for empirical treatment of infections. Approximately half (50.7%) of the patients were receiving presumptive antibiotics, and 6% were receiving prophylactic antibiotics. In total, 58.7% of prescriptions were administered parenterally, and 98.2% of patients had documentation of a stop/review date. Metronidazole (P=32.3%, T=29.2%), ceftriaxone (P=28.4%, T=19.8%) and ciprofloxacin (P=14.2%, T=14.6%) were the most common antimicrobials used. Conclusions There is a high rate of antimicrobial use among surgical inpatients, and the rate of indiscriminate antimicrobial prescribing among these patients needs to be reduced. This can be achieved by developing antimicrobial guidelines for presumptive antimicrobial therapy.

Abstract
The colon is the second most commonly injured intra-abdominal organ in penetrating trauma. Management of traumatic colon injuries has evolved significantly over the past 200 years. Traumatic colon injuries can have a wide spectrum of severity, presentation, and management options. There is strong evidence that most non-destructive colon injuries can be successfully managed with primary repair or primary anastomosis. The management of destructive colon injuries remains controversial with most favoring resection with primary anastomosis and others favor colonic diversion in specific circumstances. The historical management of traumatic colon injuries, common mechanisms of injury, demographics, presentation, assessment, diagnosis, management, and complications of traumatic colon injuries both in civilian and military practice are reviewed. The damage control revolution has added another layer of complexity to management with continued controversy.

Abstract
Objective To confirm the role of X-ray exposure in treating infected wound fractures at the lower limb and determine X-ray exposure times. Methods Fifty-one wound swabs were collected from patients with infected open fractures at the lower limb with grade II, IIIA, B, and C according to the Gustilo and Anderson classification system and then cultured. The bacterial isolates were identified by biochemical tests and the VITEK-2 System and tested against several antibiotics. The X-ray exposure was done for open fractures by radiography (at kV133 and 5 milliambers). Results The higher isolation rate was recorded for Staphylococcus aureus with 21 (41.2%) isolates, and most of them (20, 95.2%) were isolated from grade II fractures. The isolation rate of Gram-negative bacteria was 25.5% for Escherichia coli with 13 isolates, 19.6% for Pseudomonas aeruginosa with 10 isolates, and 13.7% for Klebsiella pneumoniae with 7 isolates, most of which were isolated from grade III fractures. The isolation rate of P. aeruginosa was 60% (6 isolates) from grade IIIA and 71.4% (5 isolates) from grade IIIB for K. pneumoniae, while for E. coli it was 69.2% (9 isolates) from grade IIIC. All the bacterial isolates recorded high levels of antibiotic resistance against most tested antibiotics. Wound cultures of grade II fractures appeared sterile after the first X-ray exposure, and these wounds were infected with S. aureus or P. aeruginosa. However, cultures of grade IIIA and IIIB fractures appeared sterile after the second X-ray exposure for all isolated bacteria, except for S. aureus (grade IIIA fractures) (after the third X-ray exposure). Grade IIIC fractures showed sterile culture after the third X-ray exposure for wounds infected with P. aeruginosa and E. coli. Conclusions The study concluded that X-ray exposure showed high effectiveness in treating infected open fractures.

Abstract
Purpose: Prophylactic antibiotic therapy is a standard of care for patients who present with open fractures due to the risk of infectious complications. This study was conducted to characterize the use of initial prophylactic antibiotic use in open fractures, guideline compliance, and its impact on care. Methods: Retrospective chart review of adult patients presenting with an open fracture to a Level 1 Trauma Center Emergency Department over a 12-month period was conducted. Results: Of the 202 patients meeting inclusion criteria, overall compliance with guideline recommendations for antibiotic prophylaxis was found to be 33.2%. The duration of prophylactic therapy was significantly longer in the noncompliant group and among those who received a secondary antibiotic (P < .05 for both comparisons). The duration of therapy was found to be significantly longer in those patients who developed an infection (P < .001). Those who developed an infection had a longer hospital length of stay (LOS) (P < .001) and intensive care unit LOS (P = .002). In addition, those who developed an infection had significantly more surgeries (P < .001) and received more red blood cell transfusions (P < .001). Correlation analysis confirmed a significant association between infection and duration of antibiotic prophylaxis (P = .02), number of surgeries (P < .0001), and number of transfusions (P < .0001). Conclusion: Guideline compliance was exceedingly low due to the extended duration of initial antibiotic therapy and did not appear to yield any clinical benefits. Infection was significantly associated with longer duration of initial prophylactic therapy and morbidity. Opportunities exist to elevate compliance with guidelines and to reevaluate prophylactic antimicrobial therapy in this setting.

Abstract
Damage control orthopaedics (DCO) originally consisted of the provisional immobilisation of long bone - mainly femur - fractures in order to achieve the advantages of early treatment and to minimise the risk of complications, such as major pain, fat embolism, clotting, pathological inflammatory response, severe haemorrhage triggering the lethal triad, and the traumatic effects of major surgery on a patient who is already traumatised (the “second hit” effect). In recent years, new locations have been added to the DCO concept, such as injuries to the pelvis, spine and upper limbs. Nonetheless, this concept has not yet been validated in well-designed prospective studies, and much controversy remains. Indeed, some researchers believe the indiscriminate application of DCO might be harmful and produce substantial and unnecessary expense. In this respect, too, normalised parameters associated with the acid-base system have been proposed, under a concept termed early appropriate care, in the view that this would enable patients to receive major surgical procedures in an approach offering the advantages of early total care together with the apparent safety of DCO. This paper discusses the diagnosis and treatment of severely traumatised patients managed in accordance with DCO and highlights the possible drawbacks of this treatment principle.

Abstract
Purpose A task force appointed by the Korean Society of Acute Care Surgery reviewed previously published guidelines on antibiotic use in patients with abdominal injuries and adapted guidelines for Korea. Methods Four guidelines were assessed using the Appraisal of Guidelines for Research and Evaluation II instrument. Five topics were considered: indication for antibiotics, time until first antibiotic use, antibiotic therapy duration, appropriate antibiotics, and antibiotic use in abdominal trauma patients with hemorrhagic shock. Results Patients requiring surgery need preoperative prophylactic antibiotics. Patients who do not require surgery do not need antibiotics. Antibiotics should be administered as soon as possible after injury. In the absence of hollow viscus injury, no additional antibiotic doses are needed. If hollow viscus injury is repaired within 12 hours, antibiotics should be continued for ≤ 24 hours. If hollow viscus injury is repaired after 12 hours, antibiotics should be limited to 7 days. Antibiotics can be administered for ≥7 days if hollow viscus injury is incompletely repaired or clinical signs persist. Broad-spectrum aerobic and anaerobic coverage antibiotics are preferred as the initial antibiotics. Second-generation cephalosporins are the recommended initial antibiotics. Third-generation cephalosporins are alternative choices. For hemorrhagic shock, the antibiotic dose may be increased twofold or threefold and repeated after transfusion of every 10 units of blood until there is no further blood loss. Conclusion Although this guideline was drafted through adaptation of other guidelines, it may be meaningful in that it provides a consensus on the use of antibiotics in abdominal trauma patients in Korea.

Abstract
OBJECTIVES The optimal duration of perioperative antibiotic prophylaxis (PAP) for open fractures remains controversial because of heterogeneous or unclear guidelines and highly variable prophylactic regimens in clinical practice. We aimed at testing different PAP durations under controlled conditions in a contaminated rabbit fracture model. METHODS A complete humeral osteotomy in 18 rabbits was fixed with a 7-hole locking compression plate and inoculated with Staphylococcus aureus. Cefuroxime was administered in a weight-adjusted dosage equivalent to human medicine (18.75 mg/kg). PAP was administered as a single shot only; for 24 hours; or for 72 hours in separate groups of rabbits (n = 6 per group). Infection was assessed after 2 weeks by quantitative bacteriological evaluation of the tissues and hardware. RESULTS Postoperative duration of PAP had a significant impact on the success of antibiotic prophylaxis in this model. Whereas the single-shot regimen completely failed to prevent infection, the 24-hour regimen showed a reduced infection rate (1 of 6 rabbits infected), but only the 72-hour course was able to prevent fracture-related infection in all animals in our model. CONCLUSIONS When contamination with high bacterial loads is likely (eg, in an open fracture situation), a 72-hour course of intravenous cefuroxime seems to be superior in preventing fracture-related infection in our rabbit model compared with a single-shot or 24-hour antibiotic regimen.

Abstract
When serious infections are suspected, patients are often treated empirically with broad-spectrum antibiotics while awaiting results that provide information on the bacterial class and species causing the infection, as well as drug susceptibilities. For deep-seated infections, these traditional diagnostic techniques often rely on tissue biopsies to obtain clinical samples which can be expensive, dangerous, and has the potential of sampling bias. Moreover, these procedures and results can take several days and may not always provide reliable information. This combination of time and effort required for proper antibiotic selection has become a barrier leading to indiscriminate broad-spectrum antibiotic use. Exposure to nosocomial infections and indiscriminate use of broad-spectrum antibiotics are responsible for promoting bacterial drug-resistance leading to substantial morbidity and mortality, especially in hospitalized and immunosuppressed patients. Therefore, early diagnosis of infection and targeted antibiotic treatments are urgently needed to reduce morbidity and mortality caused by bacterial infections worldwide. Reliable pathogen-specific bacterial imaging techniques have the potential to provide early diagnosis and guide antibiotic treatments.

Abstract
Open distal radius fractures are rare injuries with few studies to guide treatment. Degree of soft tissue injury and contamination may be a primary consideration to dictate timing and operative intervention. Antibiotics should be started as early as possible and include a first-generation cephalosporin. Surgical fixation remains a matter of surgeon preference: although studies support the use of definitive internal fixation, many surgeons address contaminated injuries with external fixation. Although postoperative outcomes are similar to closed injuries for low-grade open distal radius fractures, high-grade injuries with more complex fracture patterns carry a high risk of complications, poor outcomes, and repeat surgical procedures.

Abstract
Three therapeutic principles most substantially improve organ dysfunction and survival in sepsis: early, appropriate antimicrobial therapy; restoration of adequate cellular perfusion; timely source control. The new definitions of sepsis and septic shock reflect the inadequate sensitivity, specify, and lack of prognostication of systemic inflammatory response syndrome criteria. Sequential (sepsis-related) organ failure assessment more effectively prognosticates in sepsis and critical illness. Inadequate cellular perfusion accelerates injury and reestablishing perfusion limits injury. Multiple organ systems are affected by sepsis and septic shock and an evidence-based multipronged approach to systems-based therapy in critical illness results in improve outcomes.

Abstract
The Middle East region is plagued with repeated armed conflicts that affect both civilians and soldiers. Injuries sustained during war are common and frequently associated with multiple life-threatening complications. Wound infections are major consequences of these war injuries. The microbiology of war-related wound infections is variable with predominance of Gram-negative bacteria in later stages. The emergence of antimicrobial resistance among isolates affecting war-related wound injuries is a serious problem with major regional and global implications. Factors responsible for the increase in multidrug-resistant pathogens include timing and type of surgical management, wide use of antimicrobial drugs, and the presence of metallic or organic fragments in the wound. Nosocomial transmission is the most important factor in the spread of multidrug-resistant pathogens. Wound management of war-related injuries merits a multidisciplinary approach. This review aims to describe the microbiology of war-related wound infections and factors affecting their incidence from conflict areas in Iraq, Syria, Israel, and Lebanon.

Abstract
Open fractures are complex injuries associated with high morbidity and mortality. Despite advances made in fracture care and infection prevention, open fractures remain a therapeutic challenge with varying levels of evidence to support some of the most commonly used practices. Additionally, a significant number of studies on this topic have focused on open tibial fractures. A systematic approach to evaluation and management should begin as soon as immediate life-threatening conditions have been stabilized. The Gustilo classification is arguably the most widely used method for characterizing open fractures. A first-generation cephalosporin should be administered as soon as possible. The optimal duration of antibiotics has not been well defined, but they should be continued for 24 hours. There is inconclusive evidence to support either extending the duration or broadening the antibiotic prophylaxis for type Gustilo type III wounds. Urgent surgical irrigation and debridement remains the mainstay of infection eradication, although questions persist regarding the optimal irrigation solution, volume, and delivery pressure. Wound sampling has a poor predictive value in determining subsequent infections. Early wound closure is recommended to minimize the risk of infection and cannot be substituted by negative-pressure wound therapy. Antibiotic-impregnated devices can be important adjuncts to systemic antibiotics in highly contaminated or comminuted injuries. Multiple fixation techniques are available, each having advantages and disadvantages. It is extremely important to maintain a high index of suspicion for compartment syndrome, especially in the setting of high-energy trauma.

Abstract
Open tibial fractures are common injuries after high-energy trauma such as road traffic accidents. Infection is one of the main complications of open fractures. Broad-spectrum antibiotics have been used for prophylaxis and treatment of infection in these fractures. The duration of antibiotic prophylaxis remains controversial, especially for the different types and grades of open fractures. No complete review, to date, has been performed of published studies to demonstrate the wide variety of duration of antibiotic use in practice to prevent infection, especially in open tibial fractures. The purpose of the present study was to review the evidence in the current data regarding the duration of prophylactic antibiotic administration in open tibial fractures and to identify the optimum duration of administration of antibiotics to minimize the risk of infection in these fractures. We reviewed and evaluated all published clinical trials claiming or cited elsewhere as being authoritative regarding the duration of prophylactic antibiotic use in open tibial fracture management. A large number of studies reported antibiotic prophylaxis in open fractures; however, only 8 met the inclusion criteria set out for our review. Only 1 randomized, double-blind, prospective study examined the duration of prophylactic antibiotic administration in open tibial fractures. That study suggested a short course of antibiotics is as effective as a long course in infection prophylaxis. The results of the present review highlight the need for a rigorous randomized, double-blind, multicenter trial to establish an agreed protocol for the optimal length of prophylactic antibiotic administration in open tibial fractures.

Abstract
BACKGROUND Ventilator-associated pneumonia (VAP) remains a common complication in critically ill surgical patients, and its diagnosis remains problematic. Exhaled breath contains aerosolized droplets that reflect the lung microbiota. We hypothesized that exhaled breath condensate fluid (EBCF) in hygroscopic condenser humidifier/heat and moisture exchanger (HCH/HME) filters would contain bacterial DNA that qualitatively and quantitatively correlate with pathogens isolated from quantitative BAL samples obtained for clinical suspicion of pneumonia. METHODS Forty-eight adult patients who were mechanically ventilated and undergoing quantitative BAL (n = 51) for suspected pneumonia in the surgical ICU were enrolled. Per protocol, patients fulfilling VAP clinical criteria undergo quantitative BAL bacterial culture. Immediately prior to BAL, time-matched HCH/HME filters were collected for study of EBCF by real-time polymerase chain reaction. Additionally, convenience samples of serially collected filters in patients with BAL-diagnosed VAP were analyzed. RESULTS Forty-nine of 51 time-matched EBCF/BAL fluid samples were fully concordant (concordance > 95% by κ statistic) relative to identified pathogens and strongly correlated with clinical cultures. Regression analysis of quantitative bacterial DNA in paired samples revealed a statistically significant positive correlation (r = 0.85). In a convenience sample, qualitative and quantitative polymerase chain reaction analysis of serial HCH/HME samples for bacterial DNA demonstrated an increase in load that preceded the suspicion of pneumonia. CONCLUSIONS Bacterial DNA within EBCF demonstrates a high correlation with BAL fluid and clinical cultures. Bacterial DNA within EBCF increases prior to the suspicion of pneumonia. Further study of this novel approach may allow development of a noninvasive tool for the early diagnosis of VAP.

Abstract
BACKGROUND Haemophilus species bacteria (HSB) are known pathogens responsible for early pneumonia in intubated trauma patients. The primary goal of this study was to examine the incidence and extent of hypoxemia in intubated trauma patients who develop early ventilator-associated pneumonia (VAP) secondary to HSB. On the basis of our clinical experiences, we hypothesized that patients with Haemophilus species bacteria pneumonia (HSBP) would have a high rate of hypoxemia but that the effect would be transient. METHODS Retrospective review of intubated trauma patients from an urban level I trauma center with HSBP diagnosed by deep tracheal aspirate or bronchoalveolar lavage from April 2007 to November 2012. Collected variables included day of HSBP diagnosis; PaO2 to FIO2 ratio (P:F) at HSBP diagnosis as well as HSBP day three and HSBP day seven; injury severity score (ISS) and its component parts; admission Glasgow Coma Scale (GCS) score; and mortality. Hypoxemia was defined as P:F <200. χ(2) Tests were utilized to assess factors that differed between hypoxemic and non-hypoxemic patients; data are presented as median (interquartile range, IQR). RESULTS Sixty-nine patients were identified (80% male; age, 35 y [range, 24-49]; ISS 27 [9-59]). Diagnosis of HSBP occurred early (hospital day 4 [range, 3-5]). Forty-three percent of patients had acute respiratory distress syndrome (ARDS) on HSBP day 1; this decreased to 26% on day three and to 30% on day seven. Forty patients (77%) had a tracheostomy performed. Patients with hypoxemia were significantly less likely to have a severe head injury (GCS<9), p<0.05. Patients with hypoxemia had similar hospital length of stay and mortality to patients who did not develop hypoxemia. CONCLUSION Haemophilus species bacteria pneumonia in trauma patients is associated with high rates of transient hypoxemia and a high tracheostomy rate, although subsequent outcomes are not affected. Patients with head injuries had a lower incidence of hypoxemia from pneumonia.

Abstract
Infection is a major complication associated with combat-related injuries. Beside immobilization, wound irrigation, surgical debridement and delayed coverage, post-injury antimicrobials contribute to reduce combat-related infections, particularly those caused by bacteria of the early contamination flora. In modern warfare, bacteria involved in combat-related infections are mainly Gram-negative bacteria belonging to the late contamination flora. These bacteria are frequently resistant or multiresistant to antibiotics and spread through the deployed chain of care. This article exposes the principles of war wounds antimicrobial prophylaxis recommended in the French Armed Forces and highlights the need for high compliance to hygiene standard precautions, adapted contact precautions and judicious use of antibiotics in French deployed military medical treatment facilities (MTF).

Abstract
First described more than 60 years ago, the open abdomen has now become a relatively common entity in surgical ICUs. Although the indications for an open abdomen have evolved since the original description of the damage control laparotomy, the goal remains to provide an unstable or critically ill patient time to correct their physiologic derangements. Temporary abdominal closure is thus used as a bridge to definitive repair and closure. Unfortunately, the open abdomen is associated with significant morbidity and mortality, and recent studies have suggested an overuse of the technique. Once the decision is made to proceed with an open abdomen, multiple options exist for temporary abdominal closure. The hope is to obtain definitive closure shortly thereafter in an attempt to reduce potential complications including intra-abdominal infection or enteroatmospheric fistula. Options for temporary closure range from the Bogotá bag to vacuum-assisted techniques; a combined technique of sequential fascial closure with vacuum assistance has recently been shown to result in 100% fascial approximation. In situations where fascial closure is unattainable, temporary coverage with a skin graft may be employed, followed by late abdominal closure via complex abdominal herniorrhaphy. Even using advanced methods such as component separation or a “pork sandwich” technique, the complication and recurrence rates remain high. A careful understanding of the indications, optimal management, and potential complications of the open abdomen is necessary to limit its overuse and ultimately reduce some of the challenges associated with it.

Abstract
Traumatic injuries cause 5.8 million deaths per year globally. Before the advent of antibiotics, sepsis was considered almost inevitable after injury. Today infection continues to be a common complication after traumatic injury and is associated with increases in morbidity and mortality and longer hospital stays. Research into the prevention of post-traumatic infection has predominantly focused on thoracic and abdominal injuries. In addition, because research on sepsis following musculoskeletal injuries has predominantly been on open fractures. There is a paucity of research into the prevention of soft tissue infections following traumatic injuries. This review analyses the evidence for the role of prophylactic antibiotics in the management of soft tissue injuries. Emphasis is placed on assessing the strength of the presented evidence according to the Oxford Level of Evidence scale.

Abstract
CONTEXT Prophylactic antibiotics, paired with wound care and surgical intervention, is considered the standard of care for patients with open fracture. Guidelines from the Eastern Association for the Surgery of Trauma (EAST) recommend specific prophylactic antimicrobial therapy based on the type of open fracture. AIMS We quantified adherence to EAST guideline recommendations and documented the incidence of infection in patients with open fracture. SETTINGS AND DESIGN A retrospective, observational study of all patients with open fracture admitted to our facility from January 2004 to December 2008 was conducted. MATERIALS AND METHODS Patients were divided into compliant and noncompliant groups according to the EAST guideline recommendations. Compliance was defined as an appropriate spectrum of therapy for guideline suggested duration. We assessed for surgical and non-surgical site infections, and morbidity outcomes. STATISTICAL ANALYSIS Nominal data were explored using summary measures. Continuous variables were compared using the Student t-test or the Mann-Whitney U-test. Dichotomous data were compared using χ(2) statistic or Fisher's exact test. RESULTS The final analysis included 214 patients. Prophylactic antibiotics were guideline compliant in 28.5% of patients, and ranged from 10.0% in type 3b fractures to 52.7% in type 1 fractures. The most common reason for non-compliance was the use of guideline recommended coverage that exceeded the suggested duration (71.2%). Patients who received non-compliant therapy required prolonged hospital lengths of stay (6 vs. 3 days, P = 0.0001). The overall incidence of infection was similar regardless of guideline compliance (17.0% vs. 11.5%, P = 0.313). CONCLUSIONS Prophylactic antibiotics for open fracture frequently exceeded guideline recommendations in duration and spectrum of coverage, especially in more severe fracture types. Non-compliance with EAST recommendations was associated with increased in-hospital morbidity.

Abstract
Despite advances in resuscitation and surgical management of combat wounds, infection remains a concerning and potentially preventable complication of combat-related injuries. Interventions currently used to prevent these infections have not been either clearly defined or subjected to rigorous clinical trials. Current infection prevention measures and wound management practices are derived from retrospective review of wartime experiences, from civilian trauma data, and from in vitro and animal data. This update to the guidelines published in 2008 incorporates evidence that has become available since 2007. These guidelines focus on care provided within hours to days of injury, chiefly within the combat zone, to those combat-injured patients with open wounds or burns. New in this update are a consolidation of antimicrobial agent recommendations to a backbone of high-dose cefazolin with or without metronidazole for most postinjury indications, and recommendations for redosing of antimicrobial agents, for use of negative pressure wound therapy, and for oxygen supplementation in flight.

Abstract
Trauma-associated injuries of the thorax and abdomen account for the majority of combat trauma-associated deaths, and infectious complications are common in those who survive the initial injury. This review focuses on the initial surgical and medical management of torso injuries intended to diminish the occurrence of infection. The evidence for recommendations is drawn from published military and civilian data in case reports, clinical trials, meta-analyses, and previously published guidelines, in the interval since publication of the 2008 guidelines. The emphasis of these recommendations is on actions that can be taken in the forward-deployed setting within hours to days of injury. This evidence-based medicine review was produced to support the Guidelines for the Prevention of Infections Associated With Combat-Related Injuries: 2011 Update contained in this supplement of Journal of Trauma.

Abstract
BACKGROUND Resistance to broad-spectrum antibiotics by gram-negative organisms is increasing. Resistance demands more resource utilization and is associated with patient morbidity and death. We describe the implementation of infection reduction protocols, including antibiotic stewardship, and assess their impact on multi-drug-resistant (MDR) healthcare-acquired gram-negative infections. METHODS Combined infection reduction and antibiotic stewardship protocols were implemented in the surgical and trauma intensive care units at Vanderbilt University Hospital beginning in 2002. The components of the program were: (1) Protocol-specific empiric and therapeutic antibiotics for healthcare-acquired infections; (2) surgical antibiotic prophylaxis protocols; and (3) quarterly rotation/limitation of dual antibiotic classes. Continuous healthcare-acquired infection surveillance was conducted by independent practitioners using National Heath Safety Network criteria. Linear regression analysis was used to estimate trends in MDR gram-negative healthcare-acquired infections. RESULTS A total of 1,794 gram-negative pathogens were isolated from healthcare-acquired infections during the eight-year observation period. The proportion of healthcare-acquired infections caused by MDR gram-negative pathogens decreased from 37.4% (2001) to 8.5% (2008), whereas the proportion of healthcare-acquired infections caused by pan-sensitive pathogens increased from 34.1% to 53.2%. The rate of total healthcare-associated infections per 1,000 patient-days that were caused by MDR gram-negative pathogens declined by -0.78 per year (95% confidence interval [CI] -1.28, -0.27). The observed rate of healthcare-acquired infections per 1,000 patient days attributable to specific MDR gram-negative pathogens decreased over time: Pseudomonas -0.14 per year (95% CI -0.20, -0.08), Acinetobacter-0.49 per year (95% CI -0.77, -0.22), and Enterobacteriaceae -0.14 per year (95% CI -0.26, -0.03). CONCLUSION Implementation of an antibiotic stewardship protocol as a component of an infection reduction campaign was associated with a decrease in resistant gram-negative healthcare-acquired infections in intensive care units. These results further support widespread implementation of such initiatives.

Abstract
Combat injuries to the foot and ankle are challenging to treat due to frequent high-energy mechanisms, environmental contamination, and soft tissue and bony damage. Prevention and treatment of infections in injuries to the foot and ankle are critical to achieving the goals of tissue healing and restoration of function. The guidelines for treatment of these foot and ankle injuries are similar to those in place for civilians; however, allowances must be made for the realities of combat including an often austere environment, the need for evacuation, and limitations on resources available for treatment.

Abstract
Sepsis is a major cause of mortality and morbidity in the trauma patient. Sepsis following traumatic injury is related to the type of injury, together with the extent of injury and the anatomical location. Burn injuries are associated with the highest risk of sepsis. The diagnosis of sepsis in the trauma patient remains difficult. Interpretation of abnormal results is key to successful diagnosis, particularly in conjunction with clinical findings. This review will consider the specific features of sepsis in the context of trauma relating to epidemiology, risk factors, diagnosis and management.

Abstract
Mortality from battlefield wounds has historically declined, thanks to better surgical management, faster transport of casualties, and improved antibiotics. Today, one of the major challenges facing U.S. military caregivers is the presence of multidrug-resistant organisms in orthopaedic extremity wounds. The most frequently identified resistant strains of bacteria are Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter calcoaceticus-baumannii complex. Overuse of broad-spectrum antibiotics may be an important factor in building resistant strains. Acinetobacter infections appear to hospital-acquired and not from an initial colonization of the injury. More research is required to give military physicians the tools they require to reduce the infection rate and defeat multidrug-resistant organisms.

Abstract
BACKGROUND There is a paucity of data regarding whether sterile handling of endotracheal tubes (ETTs) impacts the incidence and prevalence of pneumonia in the emergency, urgent, or elective clinical scenarios. Intensive care units employ infection control and reduction schemes to reduce pneumonia rates. METHODS A MEDLINE search of the English-language literature for the last 30 years was performed using the keywords "endotracheal intubation," "intubation," "pneumonia," "sinusitis," "tracheobronchitis," "nosocomial infection," and "infection." Data were limited to those papers addressing the role of sterile handling or passage of ETTs, infection with antibiotic-resistant micro-organisms, antibiotic prophylaxis, and the role of virulence determinants in supporting invasive infection. Also, a convenience sample of a single author's patients requiring tracheal intubation was undertaken. Data were acquired on tube handling, success of insertion, and subsequent occurrence of pneumonia. RESULTS Virtually no data exist on the impact of sterile ETT handling, but unsterile manipulation of the ETT prior to insertion is common (112 of 154 intubation events). Within the limited patient sample, no conclusions may be drawn regarding the impact of unsterile handling on pneumonia rates, although sinusitis after nasotracheal intubation clearly increases the incidence of pneumonia. Biofilm generation as a facilitator of bacterial colonization of artificial airway surfaces is a ubiquitous virulence determinant that is not ameliorated by antibiotic administration. CONCLUSIONS Unsterile ETT handling and insertion techniques are not clearly associated with pneumonia induction, but physiologically sound approaches that retard biofilm production may decrease pneumonia rates.

Abstract
Violent trauma and road traffic injuries kill more than 2.5 million people in the world every year, for a combined mortality of 48 deaths per 100,000 population per year. Most trauma deaths occur at the scene or in the first hour after trauma, with a proportion from 34% to 50% occurring in hospitals. Preventability of trauma deaths has been reported as high as 76% and as low as 1% in mature trauma systems. Critical care errors may occur in a half of hospital trauma deaths, in most of the cases contributing to the death. The most common critical care errors are related to airway and respiratory management, fluid resuscitation, neurotrauma diagnosis and support, and delayed diagnosis of critical lesions. A systematic approach to the trauma patient in the critical care unit would avoid errors and preventable deaths.

Abstract
BACKGROUND Prolonged courses of broad-spectrum antibiotics are often cited as the standard of care for prevention of infective complications of open fractures. The origins of these recommendations are obscure, however, and multi-drug-resistant systemic infections attributable to antibiotic overuse are common life-threatening problems in current intensive care unit practice. OBJECTIVE To review systematically the effects of prophylactic antibiotic administration on the incidence of infections complicating open fractures. DATA SOURCES Computerized bibliographic search of published research and citation review of relevant articles. STUDY SELECTION All published clinical trials claiming to evaluate, or cited elsewhere as being authoritative regarding, the role of antibiotics in open fracture management were identified and then evaluated according to published guidelines for evidence-based medicine. Only small studies (<20 patients), practice surveys, pharmacokinetic studies, and reviews or duplicative publications presenting primary data already considered were excluded from analysis. DATA EXTRACTION Information on demographics, study dates, fracture grade, antibiotic type, duration and route of administration, surgical interventions, infection-related outcomes, and the methodologic quality of the studies was extracted by the authors. The primary results were submitted to the Therapeutic Agents Committee of the Surgical Infection Society for review prior to creation of the final consensus document. DATA SYNTHESIS Current antibiotic management of open fractures is based on a small number of studies that generally are more than 30 years old and do not reflect current management priorities in trauma and critical care. With a few noteworthy exceptions, these primary studies suffer from a variety of methodologic problems, including co-mingling of prospective and retrospective data sets, absence of or inappropriate statistical analysis, lack of blinding, or failure of randomization. CONCLUSIONS The data support the conclusion that a short course of first-generation cephalosporins, begun as soon as possible after injury, significantly lowers the risk of infection when used in combination with prompt, modern orthopedic fracture wound management. There is insufficient evidence to support other common management practices, such as prolonged courses or repeated short courses of antibiotics, the use of antibiotic coverage extending to gram-negative bacilli or clostridial species, or the use of local antibiotic therapies such as beads. Large, randomized, blinded trials are needed to prove or disprove the value of these traditional approaches. Such trials should be performed in patients with high-grade fractures who (1) are well-stratified according to the degree of local injury and (2) undergo standardized fracture and wound management. Trials also must be powered to study the effects of extended antibiotic coverage on nosocomial infections. Antibiotic regimens confirmed to improve local fracture outcomes in such studies could then be used rationally, balancing the risks of local fracture-related infections and of multi-drug-resistant systemic infections to achieve optimal global outcomes.

Abstract
This article examines the epidemiology and risk factors for the development of surgical site infections (SSIs), the importance of appropriate administration of prophylactic antibiotics, nonpharmacologic strategies, and the role of new "active" devices in reducing SSIs. A review of the pertinent English-language literature shows that many factors contribute to the risk of a patient developing an SSI. These include the patient's health status, preparation of the patient before surgery, and the use of appropriate antibiotic prophylaxis. Careful preparation of the patient and care after surgery is especially important. The use of new "active" antibacterial devices may reduce risk further. Surgeons can minimize the risk to the patient of the development of SSI through strict adherence to established surgical guidelines for perioperative care.

Abstract
OBJECTIVE To characterize the pattern of surgical antimicrobial prophylaxis in the Czech Republic. METHOD Cross sectional survey with a self-administered postal questionnaire. Data collected included use of antimicrobial prophylaxis, surgical site infection rate, pathogens causing surgical site infection and demographics of the institution. Descriptive and multivariate analyses were performed. SETTING Hospital, surgical departments in the Czech Republic. MAIN OUTCOME MEASURE Prevalence of surgical antimicrobial use, factors associated with use, the profile of antimicrobial use, timing, route, dosage regimen and duration of initiated prophylaxis. RESULT The response rate was 55.5%. Surgical antimicrobial prophylaxis was used in 97.5% of departments, and 85% departments justified prophylaxis based on guideline. The timing of the first dosage was within 2 h of operation in 95.0% of departments and 36.7% of all departments administered more than 2 doses of SAP in operations that lasted less than 4 h of all respondents. The three most common prophylactic antimicrobial agent used were cefazolin, co-amoxiclav and cefuroxime amongst the 26 single antimicrobial agents and 16 antimicrobial combinations. Penicillins and enzyme inhibitor was the most frequent class used. Surgical antimicrobial prophylaxis was administered intravenously in 82.5% of all cases. The regimen used varied markedly in dose and duration prescribed. The surgical site infection rate occurred. 1-5% in 71.7% of departments. Most departments identified the causative pathogen at all times. Staphylococcus aureus was the most frequent pathogen of surgical site infection and was detected in 90.8% of all departments. There was significant association between Pseudomonas aeruginosa with cefuroxime use and Bacteriodes fragilis with co amoxiclav use. CONCLUSION This survey has identified several areas for improvement in surgical antimicrobial prophylaxis in the Czech Republic. Particular areas of concern include route of administration, duration and timing of first dosage of SAP, and the inappropriate use of broad-spectrum antimicrobials.

Abstract
BACKGROUND Despite a large body of evidence describing care processes known to reduce the incidence of surgical site infections, many are underutilized in practice. METHODS Fifty-six hospitals volunteered to redesign their systems as part of the National Surgical Infection Prevention Collaborative, a 1-year demonstration project sponsored by the Centers for Medicare & Medicaid Services. Each facility selected quality improvement objectives for a select group of surgical procedures and reported monthly clinical process measure data. RESULTS Forty-four hospitals reported data on 35,543 surgical cases. Hospitals improved in measures related to appropriate antimicrobial agent selection, timing, and duration; normothermia; oxygenation; euglycemia; and appropriate hair removal. The infection rate decreased 27%, from 2.3% to 1.7% in the first versus last 3 months. CONCLUSIONS The Collaborative demonstrated improvement in processes known to be associated with reduced risk of surgical site infections. Quality improvement organizations can be effective resources for quality improvement in the surgical arena.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) continues to plague our hospitals. With the appearance of isolates that are resistant to vancomycin, now, more than ever, we must direct our efforts to controlling its development and spread. New antimicrobials have become available for treatment, but may only be a short-term answer. Our efforts towards control must be directed towards infection control measures such as improved hand hygiene with user-friendly products, such as alcohol-based hand disinfectants. Intranasal mupirocin may have a place in prevention of surgical site infection, although this role has not yet been clearly defined. Other areas where MRSA control may be effected include prudent controlled use of antibiotics, including surgical prophylaxis.

Abstract
In a previous study in the intensive care unit (ICU) of the Alfred Hospital, Melbourne, Australia, it was demonstrated that trauma patients were at particular risk of becoming colonized by methicillin-resistant Staphylococcus aureus (MRSA). We examined risk factors for MRSA acquisition in these patients using a cohort study comparing the 31 patients who acquired MRSA with 65 who did not. Data collected included ICU length of stay (LOS), mechanism of trauma, site of injury, type of surgery, trauma severity and antibiotic usage. Odds ratios (OR) were determined and adjusted for LOS. LOS in the ICU was a significant univariate predictor of MRSA acquisition (OR 13.7). When adjusted for LOS, mechanism of trauma (OR 10.4), laparotomy (OR 6.3) and administration of ticarcillin/clavulanic acid (OR 4.5) or glycopeptides (OR 5.9) remained significant. We confirmed our previous finding that LOS was associated with MRSA acquisition. Receipt of antibiotics correlated with reported literature. Novel associations were road trauma as a mechanism and laparotomy.

Abstract
Background The aim of this study was to determine whether prior antimicrobial therapy is an important risk factor for extended antimicrobial therapy among critically ill children. To evaluate other predisposing factors influencing the usage of antibiotics in a pediatric intensive care unit (PICU) setting. To examine the relationship between the extent of antimicrobial treatment and the incidence of nosocomial infections and outcome. Methods This prospective observational cohort study was conducted at a university-affiliated teaching hospital (760 beds) in Athens. Clinical data were collected upon admission and on each consecutive PICU day. The primary reason for PICU admission was recorded using a modified classification for mutually exclusive disease categories. All administered antibiotics to the PICU patients were recorded during a six-month period. Microbiological and pharmacological data were also collected over this period. The cumulative per patient and the maximum per day numbers of administered antibiotics, as well as the duration of administration were related to the following factors: Number of antibiotics which the patients were already receiving the day before admission, age groups, place of origin, the severity of illness, the primary disease and its complications during the course of hospitalization, the development of nosocomial infections with positive cultures, the presence of chronic disease or immunodeficiency, various interventional techniques (mechanical ventilation, central catheters), and PICU outcome. Results During a six-month period 174 patients were admitted to the PICU and received antibiotics for a total of 950 days (62.3% of the length of stay days). While in PICU, 34 patients did not receive antimicrobial treatment (19.5%), 69 received one antibiotic (39.7%), 42 two (24.1%), 17 three (9.8%), and 12 more than three (6.9%). The number of antibiotics prescribed in PICU or at discharge did not differ from that at admission. Indications for receiving antibiotics the day before admission and throughout during hospitalization into PICU were significantly correlated. Although the cumulative number of administered antibiotics did not correlate with mortality (9.8%), it was significantly related to the severity scoring systems PRISM (p < .001), TISS (p < .002) and was significantly related to the number of isolated microorganisms (p < .0001). Multiple regression analysis demonstrated that independent determinants of the cumulative number of antibiotics were: prior administration of antibiotics, presence of a bloodstream infection, positive bronchial cultures, immunodeficiency, and severity of illness. Conclusion Prior antimicrobial therapy should be recognized as an important risk factor for extended antimicrobial therapy among critically ill children. Severity of illness, immunodeficiency, and prolonged length of stay are additional risk factors.

Abstract
Traumatic injury is common, and accounts for a large health care burden. Trauma and in particular haemorrhagic shock are closely related to the onset of multiple organ failure, the systemic inflammatory response and sepsis. Despite overall improvements in the care of septic critically ill patients there has been little impact on morbidity and mortality. In recent years our understanding of sepsis both as an illness and at a molecular level has led to the development of a number of therapeutic interventions. This article outlines the current evidence for such interventions and points to possible future research that is required in the diagnosis and management of trauma-related sepsis.

Abstract
BACKGROUND The overall incidence of surgical site infection (SSI) has been estimated to be 2.8% in the United States, according to the U.S. Centers for Disease Control and Prevention, although the data may underrepresent the true incidence of such infections owing to inherent problems with voluntary self-reporting by surgeons of infections that occur in the ambulatory surgical setting. This review analyzes the reasons why patients are at risk and what can be done to minimize the risk. METHODS Review of the pertinent English-language literature. RESULTS Factors that contribute to the development of SSI include those that arise from the patient's health status, those that relate to the physical environment where surgical care is provided, and those that result from clinical interventions that increase the patient's inherent risk. Careful patient selection and preparation, including the judicious use of antibiotic prophylaxis, can decrease the overall risk of infection, especially following clean-contaminated and contaminated operations. However, antibiotics are not a substitute for attention to detail and meticulous surgical technique, and can increase the risk of nosocomial infection following injudicious use (that is, overuse). CONCLUSION Most SSIs can be attributed to risk factors inherent to the patient, rather than to inherently flawed surgical care. Nonetheless, the surgeon can minimize the risk to the patient through careful patient selection and preparation, attention to technical details and awareness of the operating room environment, and the selective use of short-duration, narrow-spectrum antibiotic prophylaxis for appropriate patients.
