Abstract
Background Antimicrobial stewardship programs can optimize antimicrobial use and have been federally mandated in all hospitals. However, best stewardship practices in immunocompromised patients with cancer are not well established. Methods An antimicrobial time out, in the form of an email, was sent to physicians caring for hospitalized patients reaching 5 days of therapy for targeted antimicrobials (daptomycin, linezolid, tigecycline, vancomycin, imipenem/cilastatin, meropenem) in a comprehensive cancer center. Physicians were to discontinue the antimicrobial if unnecessary or document a rationale for continuation. This is a quasi-experimental, interrupted time series analysis assessing antimicrobial use during the following times: period 1 (before time-out: January 2007-June 2010) and period 2 (after time-out: July 2010-March/2015). The primary antimicrobial consumption metric was mean duration of therapy. Days of therapy per 1000 patient-days were also assessed. Results Implementation of the time-out was associated with a significant decrease in mean duration of therapy for the following antimicrobials; daptomycin: -0.89 days (95% confidence interval [CI], -1.38 to -.41); linezolid: -0.89 days (95% CI, -1.27 to -.52); meropenem: -0.97 days (95% CI, -1.39 to -.56); tigecycline: -1.41 days (95% CI, -2.19 to -.63); P < .001 for each comparison. Days of therapy/1000 patient-days decreased significantly for meropenem (-43.49; 95% CI, -58.61 to -28.37; P < .001), tigecycline (-35.47; 95% CI, -44.94 to -26.00; P < .001), and daptomycin (-9.47; 95% CI, -15.25 to -3.68; P = .002). Discussion A passive day 5 time-out was associated with reduction in targeted antibiotic use in a cancer center and could potentially be successfully adopted to several settings and electronic health records.

Abstract
Early in its evolution, Enterococcus faecium acquired traits that allowed it to become a successful nosocomial pathogen. E. faecium inherent tenacity to build resistance to antibiotics and environmental stressors that allows the species to thrive in hospital environments. The continual wide use of antibiotics in medicine has been an important driver in the evolution of E. faecium becoming a highly proficient hospital pathogen.For successful prevention and reduction of nosocomial infections with vancomycin resistant E. faecium (VREfm), it is essential to focus on reducing VREfm carriage and spread. The aim of this review is to incorporate microbiological insights of E. faecium into practical infection control recommendations, to reduce the spread of hospital-acquired VREfm (carriage and infections). The spread of VREfm can be controlled by intensified cleaning procedures, antibiotic stewardship, rapid screening of VREfm carriage focused on high-risk populations, and identification of transmission routes through accurate detection and typing methods in outbreak situations. Further, for successful management of E. faecium, continual innovation in the fields of diagnostics, treatment, and eradication is necessary.

Abstract
BACKGROUND Cancer-related infections lead to increases in mortality, antibiotic use, and hospital stays. Other adverse outcomes include dose delays and reductions, which can result in suboptimal treatment outcomes. OBJECTIVES Effective implementation of risk assessment and evidence-based interventions for the prevention and treatment of infection are essential to improve care and reduce costs related to infections in patients with cancer receiving immunosuppressive therapy. METHODS The Oncology Nursing Society (ONS) Putting Evidence Into Practice (PEP) prevention of infection resource have been developed and updated to identify and disseminate the best available scientific evidence. FINDINGS Pharmacologic and nonpharmacologic interventions were evaluated, resulting in recommended for practice rating for catheter care bundles, antimicrobial prophylaxis, vaccination for specific populations, and implementation of contact precautions for resistant organisms.

Abstract
Background Vancomycin-resistant enterococci (VRE) cause severe infections among patients with malignancy, and these infections are usually preceded by gastrointestinal colonization. Methods We searched the PubMed and EMBASE databases (up to May 26, 2016) to identify studies that reported data on VRE gastrointestinal colonization among patients with solid or hematologic malignancy. Results Thirty-four studies, reporting data on 8391 patients with malignancy, were included in our analysis. The pooled prevalence of VRE colonization in this population was 20% (95% confidence interval [CI], 14%–26%). Among patients with hematologic malignancy, 24% (95% CI, 16%–34%) were colonized with VRE, whereas no studies reported data solely on patients with solid malignancy. Patients with acute leukemia were at higher risk for VRE colonization (risk ratio [RR] = 1.95; 95% CI, 1.17–3.26). Vancomycin use or hospitalization within 3 months were associated with increased colonization risk (RR = 1.92, 95% CI = 1.06–3.45 and RR = 4.68, 95% CI = 1.66–13.21, respectively). Among the different geographic regions, VRE colonization rate was 21% in North America (95% CI, 13%–31%), 20% in Europe (95% CI, 9%–34%), 23% in Asia (95% CI, 13%–38%), and 4% in Oceania (95% CI, 2%–6%). More importantly, colonized patients were 24.15 (95% CI, 10.27–56.79) times more likely to develop a bloodstream infection due to VRE than noncolonized patients. Conclusions A substantial VRE colonization burden exists among patients with malignancy, and colonization greatly increases the risk for subsequent VRE bloodstream infection. Adherence to antimicrobial stewardship is needed, and a re-evaluation of the use of vancomycin as empiric therapy in this patient population may be warranted.

Abstract
Infections due to resistant and multidrug resistant (MDR) organisms in haematology patients and haematopoietic stem cell transplant recipients are an increasingly complex problem of global concern. We outline the burden of illness and epidemiology of resistant organisms such as gram-negative pathogens, vancomycin-resistant Enterococcus faecium (VRE), and Clostridium difficile in haematology cohorts. Intervention strategies aimed at reducing the impact of these organisms are reviewed: infection prevention programmes, screening and fluoroquinolone prophylaxis. The role of newer therapies (e.g. linezolid, daptomycin and tigecycline) for treatment of resistant and MDR organisms in haematology populations is evaluated, in addition to the mobilization of older agents (e.g. colistin, pristinamycin and fosfomycin) and the potential benefit of combination regimens.

Abstract
AbstractHemodialysis-dependent patients are an important VRE source. After implementation of active surveillance for VRE targeting hemodialysis patients, the hospital-wide nosocomial VRE rate increased by 41%, but decreased by 41% among non-hemodialysis patients (P= .05). To assess the effectiveness of active surveillance, patients undergoing active surveillance should be analyzed separately from other patients.

Abstract
Consensus guidelines recommend antimicrobial stewardship in all hospitals with the following goals in mind: appropriate and judicious use of antimicrobial agents leading to increased drug safety, reduced antimicrobial utilization, reduction in the development and selection of resistant organisms, cost containment, and improved patient outcomes. Patients with cancer, especially those with hematologic malignancies and neutropenia, develop serious infections often and receive antimicrobial therapy frequently. Consequently, there is considerable opportunity to practice antimicrobial stewardship in this population. Several antimicrobial stewardship strategies such as antimicrobial restriction, cycling, prospective audit and feedback, and de-escalation have been evaluated in patients with cancer. The primary focus has been on the prevention and treatment of bacterial infections in febrile neutropenic patients. These efforts should be expanded to include fungal, viral, and other infections.

Abstract
Background Vancomycin resistant enterococcus (VRE) is a major cause of nosocomial infections in the United States and may be associated with greater morbidity, mortality, and healthcare costs than vancomycin-susceptible enterococcus. Current guidelines for the control of VRE include prudent use of vancomycin. While vancomycin exposure appears to be a risk factor for VRE acquisition in individual patients, the effect of vancomycin usage at the population level is not known. We conducted a systematic review to determine the impact of reducing vancomycin use through prescribing interventions on the prevalence and incidence of VRE colonization and infection in hospitals within the United States. Methods To identify relevant studies, we searched three electronic databases, and hand searched selected journals. Thirteen studies from 12 articles met our inclusion criteria. Data were extracted and summarized for study setting, design, patient characteristics, types of intervention(s), and outcome measures. The relative risk, 95% confidence interval, and p-value associated with change in VRE acquisition pre- and post-vancomycin prescription interventions were calculated and compared. Heterogeneity in study results was formally explored by stratified analysis. Results No randomized clinical trials on this topic were found. Each of the 13 included studies used a quasi-experimental design of low hierarchy. Seven of the 13 studies reported statistically significant reductions in VRE acquisition following interventions, three studies reported no significant change, and three studies reported increases in VRE acquisition, one of which reported statistical significance. Results ranged from a reduction of 82.5% to an increase of 475%. Studies of specific wards, which included sicker patients, were more likely to report positive results than studies of an entire hospital including general inpatients (Fisher's exact test 0.029). The type of intervention, endemicity status, type of study design, and the duration of intervention were not found to significantly modify the results. Among the six studies that implemented vancomycin reduction strategies as the sole intervention, two of six (33%) found a significant reduction in VRE colonization and/or infection. In contrast, among studies implementing additional VRE control measures, five of seven (71%) reported a significant reduction. Conclusion It was not possible to conclusively determine a potential role for vancomycin usage reductions in controlling VRE colonization and infection in hospitals in the United States. The effectiveness of such interventions and their sustainability remains poorly defined because of the heterogeneity and quality of studies. Future research using high-quality study designs and implementing vancomycin as the sole intervention are needed to answer this question.

Abstract
• Background Antibiotic misuse and noncompliance with infection control precautions have contributed to increasing levels of antimicrobial resistance in hospitals.
• Objectives To assess the extent to which resistance is monitored in infection control programs and to correlate resistance rates with characteristics of antimicrobial control policies, provider attitudes and practices, and systems-level indicators of implementation of the hand hygiene guideline of the Centers for Disease Control and Prevention.
• MethodsAn on-site survey of intensive care unit staff and infection control directors of 33 hospitals in the United States was conducted. The following data were collected: antimicrobial control policies; rates during the previous 12 months of methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, and ceftazidime-resistant Klebsiella pneumoniae; an implementation score of systems-level efforts to implement the guideline; staff attitudes toward practice guidelines; and observations of staff hand hygiene. Variables associated with resistance rates were examined for independent effects by using logistic regression.
• ResultsResistance rates for S aureus, enterococci, and K pneumoniae were 52.5%, 18.2%, and 16.0%, respectively. Ten (30.3%) hospitals had an antibiotic control policy. No statistically significant correlation was observed between staff attitudes toward practice guidelines, observed hand hygiene behavior, or having an antibiotic use policy and resistance rates. In logistic regression analysis, higher scores on measures of systems-level efforts to implement the guideline were associated with lower rates of resistant S aureus and enterococci (P=.046).
• Conclusions Organizational-level factors independent of the practices of individual clinicians may be associated with rates of antimicrobial resistance.

Abstract
The prevention of infection is an important outcome to measure in patients with cancer because infectious complications are a significant cause of morbidity and mortality. Nurses play a vital role in the prevention of infection in patients with cancer through nursing practice, research, and patient education. However, many common nursing interventions to prevent infection are based on tradition or expert opinion and have not been subjected to scientific examination. The 2005 Oncology Nursing Society Prevention of Infection Outcomes Intervention Project Team reviewed, critiqued, and summarized the research evidence for nursing interventions to prevent infections in patients with cancer. Pharmacologic and nonpharmacologic interventions were included because many advanced practice nurses prescribe medications. This article is an evidence-based review of nursing interventions to prevent infection in patients with cancer.

Abstract
Antibiotic misuse is associated with emergence of resistance and high expenditures. Fluoroquinolones (FQ) and carbapenems (CP) are drugs with considerable potential of resistance development and its disseminated use is a concern. We undertook a prospective clinical audit to evaluate prescriptions of FQ and CP in a multistep process. Each prescription was unfolded in the following steps: indication for antimicrobial therapy; adequacy of initial prescription, dosage and route; previous cultures; and parenteral-oral transition. There was no antibiotics indication in 8.9% of FQ and 1.5% of CP group (p = 0.07). In CP 25.8% of initial schemes were inappropriate (21% in FQ). Lack of switch to oral therapy comprised 25% of monthly costs of FQ. Inadequacy in initial choice accounted for 13.6% of CP expenses. We concluded that, in spite of infection control restrictive policies, inappropriateness of antibiotic usage is worrisome. Clinical audit in a multistep approach may identify possible flaws in this process.

Abstract
Antimicrobial misuse results in the development of resistance and superbugs. Over recent decades, resistance has been increasing despite continuing efforts to control it, resulting in increased mortality and cost. Many authorities have proposed local, regional and national guidelines to fight against this phenomenon, and the usefulness of these programmes has been evaluated. Multifaceted intervention seems to be the most efficient method to control antimicrobial resistance. Monitoring of bacterial resistance and antibiotic use is essential, and the methodology has now been homogenized. The implementation of guidelines and infection control measures does not control antimicrobial resistance and needs to be reinforced by associated measures. Educational programmes and rotation policies have not been evaluated sufficiently in the literature. Combination antimicrobial therapy is inefficient in controlling antimicrobial resistance.

Abstract
OBJECTIVES Comorbidities are often included in risk-factor models for nosocomial antibiotic-resistant bacterial infections, and aggregate comorbidity measures are valuable because they allow one variable to represent many. This study aimed to develop new aggregate comorbidity measures based upon the Chronic Disease Score (CDS) for assessing the comorbidity-attributable risk of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) nosocomial infections. STUDY DESIGN AND SETTING For each outcome, two retrospective cohort studies of hospitalized patients were conducted. Outcomes were a first MRSA or VRE positive clinical culture obtained 48 hours or more postadmission. Each cohort was divided into development (July 1998-2001) and validation (August 2001-2003) samples. New comorbidity measures were created for MRSA (CDS-MRSA), VRE (CDS-VRE), or any nosocomial infection outcome (CDS-ID) using logistic regression and subsequently validated. Model discrimination was measured using the c-statistic. RESULTS Discrimination of the CDS-MRSA (c=0.60), CDS-VRE (c=0.65), and CDS-ID (MRSA: c=0.57; VRE: c=0.64) was greater than that of the original CDS (MRSA: c=0.52; VRE: c=0.57). CONCLUSION The CDS-MRSA, CDS-VRE, and CDS-ID are new infectious disease specific comorbidity risk-adjustment measures that will be useful for the quality of future epidemiologic studies of MRSA, VRE, and other infectious diseases.

The study was carried out by reviewing all medical records of patients who received a glycopeptide in a hospital located in Italy. A total of 452 patients received glycopeptides, with a rate of inappropriate use of 90.9%. Appropriateness of glycopeptide prescriptions was significantly higher in Intensive Care Units compared with surgical wards (odds ratio (OR) = 0.03; 95% confidence interval (CI) = 0.01-0.14), in younger patients (OR = 0.97; 95% CI = 0.95-0.99) and in those patients who received the prescription for therapy rather than prophylaxis (OR = 0.2; 95% CI = 0.06-0.66). Models were also developed to predict appropriateness of glycopeptide indications for therapy and prophylaxis. The information obtained in our audit may enable development of strategies to improve physician prescribing patterns.

Abstract
Although at first sight the spread of glycopeptide-resistant enterococci (GREs) appears to be following the same unrelenting path as that of methicillin-resistant Staphylococcus aureus, closer inspection of the Literature indicates success of certain interventions, particularly the control of antibiotic usage. There are grounds for optimism that assiduous application of antibiotic control and other infection control measures may further reduce the prevalence of GREs.

Abstract
Glycopeptide-resistant enterococci (GRE) have become a focus of concern in many countries because options for antimicrobial therapy of GRE infection are limited. Several guidelines for the control and prevention of GRE colonization and infection have been developed for healthcare settings, and occasional journal articles now report "control" (usually relative reduction of incidence or prevalence rate rather than elimination) of GRE infections. Yet, rates of infection and colonization with GREcontinue to climb in many parts of the world, showing that true control has not been achieved. Programmes to control GRE will be effective only when they (1) are less expensive to implement; (2) are shown to be cost-effective despite the fact that they merely reduce prevalence levels rather than eradicating the problem; (3) do not require almost perfect implementation to be effective; (4) are shown to be sustainable; (5) are shown to work in acute-care settings other than selected academic centres; and (6) are shown to work in non-acute care settings. Until then, it is clear that guidelines for control of GRE have not worked. New guidelines that truly control GRE must be developed, and this must be done quickly.
