Clinical and molecular characterization of community-onset urinary tract infections due to extended-spectrum cephalosporin-resistant Enterobacteriaceae.
The objective of this paper was to evaluate risk factors for and molecular characteristics of community-onset extended-spectrum cephalosporin-resistant (ESC-R) Enterobacteriaceae (EB) urinary tract infections (UTIs) in a US health system. The investigators found that use of trimethoprim-sulfamethoxazole, older age, diabetes, and presentation to the emergency department were associated with community-onset ESC-R EB UTI, with a high prevalence of CTX-M among their community isolates.

Topical decolonization does not eradicate the skin microbiota of community-dwelling or hospitalized adults.
The authors compared microbial communities and levels of richness and diversity in community-dwelling subjects and in intensive care unit patients before and after the use of topical decolonization protocols. They found a reduction in S. aureus without eradicating endogenous microbiota.

Differences in prevalence of community-associated MRSA and MSSA among U.S. and non-U.S. born populations in six New York community health centers.
As part of a research collaborative, 6 New York City-area community health centers recruited patients with Skin and Soft Tissue Infections (SSTIs). This study found that although not statistically significant, immigrants had lower rates of Methicillin-Resistant Staphylococcus aureus (MRSA) infections than did native-born participants, and immigrants showed significantly higher rates of Methicillin-Susceptible Staphylococcus aureus (MSSA) wound cultures.

Impact of delays between Clinical and Laboratory Standards Institute and Food and Drug Administration revisions of interpretive criteria for carbapenem-resistant enterobacteriaceae.
The authors used their Regional Healthcare Ecosystem Analyst (RHEA) simulation model and found that the 32-month delay in changing carbapenem-resistant Enterobacteriaceae (CRE) breakpoints might have resulted in 1,821 additional carriers in Orange County, CA. They recommend that policymakers aim to minimize the delay in the adoption of new breakpoints for antimicrobials against emerging pathogens when containment of spread is paramount, ideally less than 1.5 years.

Implementing an antimicrobial stewardship program in out-patient dialysis units.
The purpose of this review is to highlight the key elements and interventions of antimicrobial stewardship programs (ASP). The Infectious Disease Society of America and the Society of Healthcare Epidemiology of America have provided evidence-based guidelines for the development and implementation of an ASP. Many of their recommendations can be adapted to the out-patient dialysis setting.

Identification of novel microbes associated with pelvic inflammatory disease and infertility.
The authors examined the relationship between select novel bacteria, pelvic inflammatory disease (PID), and long-term sequelae. They demonstrated that S. sanguinegens, S. amnionii, BVAB1 and A. vaginae are associated with PID and suggested that optimal antibiotic regimens for PID may require coverage of novel bacterial vaginosis-associated microbes.

What drives variation in antibiotic prescribing for acute respiratory infections?
This study sought to identify the underlying factors driving variation in antibiotic prescribing across clinicians and settings. The investigators concluded that poor-quality antibiotic prescribing was associated with feeling rushed, believing less strongly that antibiotics were overused, and believing that patient demand was not an issue, factors that can be assessed and addressed in future interventions.

Evaluating infection prevention strategies in out-patient dialysis units using agent-based modeling.
The researchers hypothesized that targeting patients receiving antimicrobial treatment would more effectively reduce transmission and acquisition of multidrug-resistant organisms (MDRO) and further that environmental contamination plays a role in the dissemination of MDRO in the dialysis unit. They found that reducing antimicrobial treatment markedly reduces overall colonization rates and also the levels of environmental contamination in the dialysis unit. They suggested that improving the environmental decontamination efficacy between patient dialysis treatments as an effective method for reducing colonization and contamination rates.

Pneumonia identification using nursing home records.
The researchers compared three established strategies for defining pneumonia using records from 1,119 residents across 16 nursing homes. They found that recorded diagnosis of pneumonia is a highly sensitive and pragmatic method to ascertain pneumonia in nursing homes, and is recommended for use in quality improvement and research.

Risk of infection following colonization with carbapenem-resistant Enterobactericeae: a systematic review.
The authors examined the risk of developing infection among those colonized with carbapenem-resistant enterobacteriaceae (CRE). They found an overall 16.5% risk of infection with CRE, with the most common site of infection being the lung. They concluded that, given the high mortality rate observed with CRE infection and the difficulty in treating these infections, research to investigate and develop strategies to eliminate the colonization state are needed.

Use of the health belief model to study patient perceptions of antimicrobial stewardship in the acute care setting.
The authors identified themes associated with patient perceptions of antibiotic use and the role of patients in inpatient antimicrobial stewardship. They found that general medicine inpatients receiving at least one anti-infective medication recognized antibiotic resistance as a serious public health threat but expressed low perceived susceptibility to being personally affected by antibiotic resistance. Few participants reported being offered the opportunity to engage in shared decision making while hospitalized. The researchers concluded that the likelihood of patient engagement in stewardship practices is currently limited by low perceived susceptibility and lack of cues to act.

Using clinical vignettes to assess quality of care for acute respiratory infections.
Overprescribing of antibiotics for acute respiratory infections (ARIs) is common. The objective of this study was to develop and validate a vignette-based method to estimate clinician ARI antibiotic prescribing. The researchers concluded that responses to 3 clinical vignettes can identify clinicians with relatively poor quality ARI antibiotic prescribing. Vignettes may be a mechanism to target clinicians for quality improvement efforts.

Long-term carriage of ciprofloxacin-resistant Escherichia coli Isolates in high-risk nursing home residents.
This paper's objective was to characterize the incidence and duration of carriage of ciprofloxacin-resistant Escherichia coli (CipREc) in nursing homes and to identify those in the O25b-ST131 lineage. The authors found that CipREc occurred frequently in nursing home residents and is carried for long durations, and that reacquisition following clearance is common.

Increased vancomycin exposure and nephrotoxicity in children: therapeutic does not mean safe.
The authors argue that a tenuous balance exists between the successful treatment of infection and the safe administration of vancomycin in the most vulnerable patients. Furthermore, prospective controlled trials are needed to identify and validate the optimal pharmacokinetic/pharmacodynamic (PK/PD) targets for vancomycin in children. Also, infectious diseases specialists need to be cognizant of the untoward effects of nephrotoxic acute kidney injury in children.

A nationwide analysis of antibiotic use in hospice care in the final week of life.
This study uses data form the 2007 National Home and Hospice Care Survey to estimate antibiotic utilization in hospice care patients and identify potential infectious indications and facility and patient characteristics associated with antibiotic use in this population. It found that 27 percent of hospice patients received an antibiotic during the last seven days of life, most without a documented infectious diagnosis.
