Because of the increasing development of antimicrobial resistance, there is a greater responsibility within the medical community to limit the exposure of patients to antibiotics. We tested the hypothesis that shorter courses of antibiotics are associated with similar or better results than longer durations. We also sought to investigate the difference between a fixed duration of therapy and one based on physiologic measures such as fever and leukocytosis. ⋯ Shorter courses of antibiotics were associated with similar or fewer complications than prolonged therapy. In general, adopting a strategy of a fixed duration of therapy, rather than basing duration on resolution of fever or leukocytosis, appeared to yield similar outcomes with less antibiotic use.

Influence of broad-spectrum antibiotic prophylaxis on intracranial pressure monitor infections and subsequent infectious complications in head-injured patients.
The benefit of antibiotic prophylaxis for intracranial pressure (ICP) monitors remains controversial, and clinical practice varies widely. Whether any antibiotic coverage, particularly broad-spectrum coverage, reduces monitor-related infections remains unproved, and exposure to antibiotics may affect the susceptibility patterns of pathogens producing subsequent infectious complications. Despite the lack of data supporting its use, our level I trauma center had a long-standing ICP monitor prophylaxis protocol that provided broad-spectrum coverage that included ceftriaxone. In April 2002, a protocol change was instituted that substituted cefazolin for ceftriaxone as single-agent prophylaxis for ICP monitors. ⋯ Broad-spectrum antibiotic prophylaxis of ICP monitors does not reduce CNS infections, but is associated with a shift to resistant gram-negative pathogens in subsequent infectious complications. Thus, broad-spectrum antibiotic prophylaxis of ICP monitors should be eliminated or minimized unless data from randomized trials prove its utility.

The open abdomen in trauma: do infectious complications affect primary abdominal closure?
One of the primary goals of damage control surgery in the trauma patient is primary closure of the abdomen. We hypothesized that extra-abdominal infections, such as those complicating injuries to the thorax, diaphragm, long bones, or musculoskeletal system, would decrease the likelihood of primary abdominal closure and increase hospital resource utilization in patients requiring open abdominal management. ⋯ Inability to achieve primary abdominal closure was associated with infectious complications (VAP, BSI, and SSI) and large transfusion requirements. Infectious complications also significantly increased ICU utilization and hospital charges. Death was associated with BSI, femur fractures, and large transfusion requirements, whereas infectious complications did not have a significant impact on discharge disposition.

ReviewSurgical Infection Society guideline: prophylactic antibiotic use in open fractures: an evidence-based guideline.
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. ⋯ 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.

Can the clinical pulmonary infection score impact ICU antibiotic days?
The Clinical Pulmonary Infection Score (CPIS) has been used in the intensive care unit (ICU) as a decision tool for initiation of antibiotics in suspected pneumonia and also for discontinuing antibiotics if the CPIS score is
6 on day one receiving antibiotics empirically for pneumonia. ⋯ This prospective evaluation confirms that 50% of antibiotic-days in our ICU are used empirically for pneumonia when that infection is not likely to be present by either CDC or CPIS criteria. Although the CPIS has good reliability and acceptable sensitivity and specificity, PC review and CPIS
