Antibiotic practice patterns for extremity wound infections among blast-injured subjects
INTRODUCTION: We examined antibiotic management of combat-related extremity wound infections (CEWI) among wounded US military personnel (2009–2012). METHODS: Patients were included if they sustained blast injuries, resulting in ≥1 open extremity wound, were admitted to participating US hospitals, developed a CEWI (osteomyelitis or deep soft-tissue infections) within 30 days post-injury, and received ≥3 days of relevant antibiotic(s) for treatment. RESULTS: Among 267 patients, 133 (50%) had only a CEWI, while 134 (50%) had a CEWI plus concomitant non-extremity infection. In the pre-diagnosis period (4–10 days prior to CEWI diagnosis), 95 (36%) patients started a new antibiotic with 28% of patients receiving ≥2 antibiotics. During CEWI diagnosis week (±3 days of diagnosis), 209 (78%) patients started a new antibiotic (71% with ≥2 antibiotics). In the week following diagnosis (4–10 days after CEWI diagnosis), 121 (45%) patients started a new antibiotic with 39% receiving ≥2 antibiotics. Restricting to ±7 days of CEWI diagnosis, patients commonly received two (35%) or three (27%) antibiotics with frequent combinations involving carbapenem, vancomycin, and fluoroquinolones. CONCLUSIONS: Substantial variation in antibiotic prescribing patterns related to CEWIs warrants development of combat-related clinical practice guidelines beyond infection prevention, to include strategies to reduce use of unnecessary antibiotics and improve stewardship.

Early Infections Complicating the Care of Combat Casualties from Iraq and Afghanistan
Background: During the conflicts in Iraq and Afghanistan, more than 52,000 U.S. military members were wounded in action. The battlefield mortality rate was lower than in past conflicts, however, those surviving often had complex soft tissue and bone injuries requiring multiple surgeries. This report describes the rates, types, and risks of infections complicating the care of combat casualties. Patients and Methods: Infection and microbiology data obtained from the Trauma Infectious Disease Outcomes Study (TIDOS), a prospective observational study of infections complicating deployment-related injuries, were used to determine the proportion of infection, types, and associated organisms. Injury and surgical information were collected from the Department of Defense Trauma Registry. Multivariable Cox proportional hazards and logistic regression models were used to evaluate potential factors associated with infection. Results: From 2009–2012, 1,807 combat casualties were evacuated to U.S. TIDOS-participating hospitals. Among the 1,807 patients, the proportion of overall infections from time of injury through initial U.S. hospitalization was 34% with half being skin, soft tissue, or bone infections. Infected wounds most commonly grew Enterococcus faecium, Pseudomonas aeruginosa, Acinetobacter spp. or Escherichia coli. In the multivariable model, amputation, blood transfusions, intensive care unit admission, injury severity scores, mechanical ventilation, and mechanism of injury were associated with risk of infection. Conclusions: One-third of combat casualties from Iraq and Afghanistan develop infections during their initial hospitalization. Amputations, blood transfusions, and overall injury severity are associated with risk of infection, whereas more easily modifiable factors such as early operative intervention or antibiotic administration are not.

Osteomyelitis Risk Factors Related to Combat Trauma Open Tibia Fractures: A Case-control Analysis
OBJECTIVES: We assessed osteomyelitis risk factors in U.S. military personnel with combat-related open tibia fractures (2003–2009). METHODS: Patients with open tibia fractures who met diagnostic criteria of osteomyelitis were identified as cases using Military Health System data and verified through medical record review. Controls were patients with open tibia fractures who did not meet osteomyelitis criteria. Gustilo-Andersen (GA) fracture classification scheme was modified to include transtibial amputations (TTAs) as the most severe level. Logistic regression multivariable odds ratios (OR; 95% confidence interval [CI]) were assessed. RESULTS: A total of 130 tibia osteomyelitis cases and 85 controls were identified. Excluding patients with TTAs, osteomyelitis cases had significantly longer time to radiographic union compared to controls (median: 210 versus 165 days). Blast injuries, antibiotic bead utilization, ≥GA-IIIb fractures (highest risk with TTA [OR: 15.10; CI: 3.22–71.07]) and foreign body at fracture site were significantly associated with developing osteomyelitis. In a separate model, the Orthopaedic Trauma Association Open Fracture Classification muscle variable was significant with increasing risk from muscle loss (OR: 5.62; CI: 2.21–14.25) to dead muscle (OR: 8.46; CI: 3.31–21.64). When TTAs were excluded, significant risk factors were similar and included sustaining an injury between 2003 and 2006. CONCLUSIONS: Patients with severe blast trauma resulting in significant muscle damage are at the highest risk for osteomyelitis. The time period association coincides with a timeframe when several trauma system practice changes were initiated (e.g., increased negative pressure wound therapy, decreased high pressure irrigation, and reduced crystalloid use). LEVEL OF EVIDENCE: Prognostic Level III

Osteomyelitis Risk Factors Related to Combat Trauma Open Upper Extremity Fractures: A Case-control Analysis
OBJECTIVE: To determine risk factors for osteomyelitis in United States military personnel with combat-related, extremity long bone (humerus, radius, ulna) open fractures. DESIGN: Retrospective observational case-control study. SETTING: U.S. military regional hospital in Germany and tertiary care military hospitals in United States (2003-2009). PATIENTS/PARTICIPANTS: Sixty-four patients with open upper extremity fractures who met diagnostic osteomyelitis criteria (medical record review verification) were classified as cases. Ninety-six patients with open upper extremity fractures who did not meet osteomyelitis diagnostic criteria were included as controls. INTERVENTION: not applicable. MAIN OUTCOME MEASUREMENTS: Multivariable odds ratios (OR; 95% confidence interval [CI]). RESULTS: Among patients with surgical implants, osteomyelitis cases had longer time to definitive orthopaedic surgery compared to controls (median: 26 versus 11 days; p<0.001); however, there was no significant difference with timing of radiographic union. Being injured between 2003 and 2006, use of antibiotic beads, Gustilo Anderson [GA] fracture classification (highest with GA-IIIb: [OR: 22.20; CI: 3.60-136.95]), and Orthopaedic Trauma Association Open Fracture Classification skin variable (highest with extensive degloving [OR: 15.61; CI: 3.25-74.86]) were independently associated with osteomyelitis risk. Initial stabilization occurring outside of the combat zone was associated with reduced risk of osteomyelitis. CONCLUSIONS: Open upper extremity fractures with severe soft-tissue damage have the highest risk of developing osteomyelitis. The associations with injuries sustained 2003-2006 and location of initial stabilization are likely from evolving trauma system recommendations and practice patterns during the timeframe.

Is Bone Loss or Devascularization Associated With Recurrence of Osteomyelitis in Wartime Open Tibia Fractures?
BACKGROUND: During recent wars, 26% of combat casualties experienced open fractures and these injuries frequently are complicated by infections, including osteomyelitis. Risk factors for the development of osteomyelitis with combat-related open tibia fractures have been examined, but less information is known about recurrence of this infection, which may result in additional hospitalizations and surgical procedures. QUESTIONS/PURPOSES: (1) What is the risk of osteomyelitis recurrence after wartime open tibia fractures and how does the microbiology compare with initial infections? (2) What factors are associated with osteomyelitis recurrence among patients with open tibia fractures? (3) What clinical characteristics and management approaches are associated with definite/probable osteomyelitis as opposed to possible osteomyelitis and what was the microbiology of these infections? METHODS: A survey of US military personnel injured during deployment between March 2003 and December 2009 identified 215 patients with open tibia fractures, of whom 130 patients developed osteomyelitis and were examined in a retrospective analysis. No patients with bilateral osteomyelitis were included. Twenty-five patients meeting osteomyelitis diagnostic criteria were classified as definite/probable (positive bone culture, direct evidence of infection, or symptoms with culture and/or radiographic evidence) and 105 were classified as possible (bone contamination, organism growth in deep wound tissue, and evidence of local/systemic inflammation). Patients diagnosed with osteomyelitis were treated with débridement and irrigation as well as intravenous antibiotics. Fixation hardware was retained until fracture union, when possible. Osteomyelitis recurrence was defined as a subsequent osteomyelitis diagnosis at the original site ≥ 30 days after completion of initial treatment. This followup period was chosen based on the definition of recurrence so as to include as many patients as possible for analysis. Factors associated with osteomyelitis ...

Combat-Related Extremity Wounds: Injury Factors Predicting Early Onset Infections
We examined risk factors for combat-related extremity wound infections (CEWI) among U.S. military patients injured in Iraq and Afghanistan (2009–2012). Patients with ≥1 combat-related, open extremity wound admitted to a participating U.S. hospital (≤7 days postinjury) were retrospectively assessed. The population was classified based upon most severe injury (amputation, open fracture without amputation, or open soft-tissue injury defined as non-fracture/non-amputation wounds). Among 1271 eligible patients, 395 (31%) patients had ≥1 amputation, 457 (36%) had open fractures, and 419 (33%) had open soft-tissue wounds as their most severe injury, respectively. Among patients with traumatic amputations, 100 (47%) developed a CEWI compared to 66 (14%) and 12 (3%) patients with open fractures and open soft-tissue wounds, respectively. In a Cox proportional hazard analysis restricted to CEWIs ≤30 days postinjury among the traumatic amputation and open fracture groups, sustaining an amputation (hazard ratio: 1.79; 95% confidence interval: 1.25–2.56), blood transfusion ≤24 hours postinjury, improvised explosive device blast, first documented shock index ≥0.80, and >4 injury sites were independently associated with CEWI risk. The presence of a non-extremity infection at least 4 days prior to a CEWI diagnosis was associated with lower CEWI risk, suggesting impact of recent exposure to directed antimicrobial therapy. Further assessment of early clinical management will help to elucidate risk factor contribution. The wound classification system provides a comprehensive approach in assessment of injury and clinical factors for the risk and outcomes of an extremity wound infection.

Epidemiology of Trauma-Related Infections among a Combat Casualty Cohort after Initial Hospitalization: The Trauma Infectious Disease Outcomes Study
Background: The Trauma Infectious Disease Outcomes Study (TIDOS) cohort follows military personnel with deployment-related injuries in order to evaluate short- and long-term infectious complications. High rates of infectious complications have been observed in more than 30% of injured patients during initial hospitalization. We present data on infectious complications related to combat trauma after the initial period of hospitalization. Patients and Methods: Data related to patient care for military personnel injured during combat operations between June 2009 and May 2012 were collected. Follow-up data were captured from interviews with enrolled participants and review of electronic medical records. Results: Among 1,006 patients enrolled in the TIDOS cohort with follow-up data, 357 (35%) were diagnosed with one or more infection during their initial hospitalization, of whom 160 (45%) developed a trauma-related infection during follow-up (4.2 infections per 10,000 person-days). Patients with three or more infections during the initial hospitalization had a significantly higher rate of infections during the follow-up period compared with those with only one inpatient infection (incidence rate: 6.6 versus 3.1 per 10,000 days; p < 0.0001). There were 657 enrollees who did not have an infection during initial hospitalization, of whom 158 (24%) developed one during follow-up (incidence rate: 1.6 per 10,000 days). Overall, 318 (32%) enrolled patients developed an infection after hospital discharge (562 unique infections) with skin and soft-tissue infections being predominant (66%) followed by osteomyelitis (16%). Sustaining an amputation or open fracture, having an inpatient infection, and use of anti-pseudomonal penicillin (≥7 d) were independently associated with risk of an extremity wound infection during follow-up, whereas shorter hospitalization (15–30 d) was associated with a reduced risk. Conclusions: Combat-injured patients have a high burden of infectious complications that continue long after the initial ...
