Tan C, Ofner M, Candon HL, Reel K, Bean S, Chan AK, Leis JA. An ethical framework adapted for infection prevention and control. Infect Control Hosp Epidemiol 2023; 44:2044-2049. [PMID: 37424230 PMCID: PMC10755160 DOI: 10.1017/ice.2023.121] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 04/18/2023] [Accepted: 05/22/2023] [Indexed: 07/11/2023]
Abstract
OBJECTIVE The ethical implications of infection prevention and control (IPAC) are recognized, yet a framework to guide the application of ethical principles is lacking. We adapted an ethical framework to provide a systematic approach for fair and transparent IPAC decision making. METHODS We conducted a literature search for existing ethical frameworks in IPAC. Working with practicing healthcare ethicists, an existing ethical framework was adapted for use in IPAC. Indications were developed for application to practice, with integration of ethical principles and process conditions specifically relevant to IPAC. Practical refinements were made to the framework based on end-user feedback and application to 2 real-world situations. RESULTS In total, 7 articles were identified that discussed ethical principles within IPAC, but none proposed a systematic framework to guide ethical decision making. The adapted framework, named the Ethical Infection Prevention and Control (EIPAC) framework, takes the user through 4 intuitive and actionable steps, centering key ethical principles that facilitate reasoned and just decision making. In applying the EIPAC framework to practice, weighing the predefined ethical principles in different scenarios was a challenge. Although no hierarchy of principles can apply to all contexts in IPAC, our experience highlighted that the equitable distribution of benefits and burdens, and the proportional impacts of options under review, are particularly important considerations for IPAC. CONCLUSIONS The EIPAC framework can serve as an actionable ethical principles-based decision-making tool for use by IPAC professionals encountering complex situations in any healthcare context.

Abstract
BACKGROUND Patient isolation is widely recommended and used in healthcare institutions to prevent transmission of MDRO. However, its risk-benefit ratio is debated. AIM We undertook a systematic literature review and meta-analysis since 2009 to assess, based on the newly published studies, whether or not there are physical and psychological adverse events associated with patient isolation. METHODS Systematic literature review and meta-analysis were performed in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Studies were systematically searched from PubMed, from the 1st of may 2009 till the 31st of January 2020. The concepts of the research questions were defined as: "Adverse events", "patient isolation or cohorting", and "multi-drug resistant organisms colonized or infection patients". Three reviewers independently screened studies and extracted data. All statistical analysis was performed with Stata Software and R. FINDINGS After screening titles of 15921 articles, abstracts of 196 and reviewing full texts of 50 studies, we included 19 studies. Studies were divided into 3 groups: 4 qualitative studies, 7 observational studies suitable for meta-analysis and 8 other observational studies. Meta-analysis shows no adverse events related to clinical care or patient's experience associated with patient isolation. CONCLUSIONS More studies with correct methodology, including a control group and standardized inclusion criteria, must be conducted to confirm our results.

Abstract
Active surveillance cultures and contact precautions is a strategy to control the transmission of methicillin-resistant Staphylococcus aureus (MRSA) within healthcare facilities. Whether to implement this strategy to routinely screen and isolate inpatients with MRSA in non-outbreak (endemic) settings, or to remove it and use standard infection control precautions only is scientifically and ethically controversial, in view of the potential adverse effects of contact precautions on patients. To support the use of standard precautions only, it has been argued that active surveillance to identify patients who are asymptomatically colonised with MRSA to place them in contact precautions is unjust or unfair to these patients in various ways. This paper will unpack and examine four distinct arguments, which are advanced from a medical ethics or quality improvement ethical framework, for why this is so. Our analysis shows that while these arguments highlight the injustice of current practices, they do not provide strong ethical reasons for justifying the removal of active surveillance and contact precautions to control MRSA transmission and infection. An implication of our arguments is that the ethical frame for evaluating prevention and control strategies for MRSA, a multi-drug resistant bacteria, should shift from healthcare to primarily public health. From a public health ethics perspective, whether a strategy is unjust, or how ethically significant its lack of fairness is, depends on assessing the evidence for its public health effectiveness and necessity in a given setting, and the extent of the harms and burdens patients with MRSA bear when they are on contact precautions, which remain matters of scientific debate or uncertainty. As an ethical consideration in the debate, the chief normative implication of justice is to provide us further reasons to revise current active surveillance-contact precautions practices, and for the need for research and interventions to minimise their potential adverse effects on patients.

Abstract
Background: Multidrug-resistant organisms (MDROs) are an important health care issue. Patients in Western societies often present an increased morbidity of chronic conditions accompanied by poor immune status and the use of devices. In particular, patients in palliative care (PC) are at greater risk of MDRO colonization, due to accompanying special devices and being hospitalized. Objective: To gain an overview of the literature regarding MDROs in PC. Design: Systematic review Data sources: On the 19th of October 2019 the databases " PubMed" and " CINAHL" were used to identify studies reporting on MDROs in PC; the search was updated on 16th of May 2020. Results: Seventeen out of 486 articles were included. Six represent qualitative data, 10 quantitative data, and one a mixed methods approach. Prevalence data range from 4.0% to 18%. MDRO colonization has a negative impact on patients and families. It leads to uncertainties and higher workload by staff members. Strategies for the management of MDROs in the field of PC are predominantly available for methicillin-resistant Staphylococcus aureus. Not even half of institutions utilize existing protocols. Recommendations for dealing with MDROs indicate required staff and time resources as well as information, communication, and specific knowledge. Conclusion: There is a great need for studies examining the prevalence of all MDROs in the PC setting. Additionally, not only patients but also a public enlightenment on MDROs should be provided to decrease knowledge gaps and therefore reduce transmission on MDROs.

Abstract
The approach to public health, patient safety and quality of care has led to analysing health situations or problems from a population perspective, in a wide way and giving priority to factors that can normally be left in the background from a clinical point of view. For years, the problem of the use and abuse of antimicrobials, the increase and diffusion of microorganisms resistant to them, cross-transmission, and healthcare related infections have been prioritised both nationally and internationally. To combat these problems, various strategies are being developed and put into practice, from the policies of rational use and optimization of antimicrobials, surveillance, and control of infections related to health care, to training information and awareness strategies. One of the pillars of surveillance and control is the correct application of standard and specific precautions, which within the framework of these comprehensive programs aim to control the transmission of microorganisms of special microbiological and/or epidemiological interest through a series of measures. In hospitals, the application of these precautions (single room, barrier measures, restrictions on access to rooms, waste management…) in patients infected or colonised by these microorganisms can have different repercussions, both for patients and the professionals that attend them, and it is considered pertinent that the protocols and/or programs of specific precautions explicitly include the analysis of the ethical aspects in their preparation, implementation, and monitoring.

Abstract
OBJECTIVE To systematically review the literature exploring the impact of isolation on hospitalised patients who are infectious: psychological and non-psychological outcomes. DESIGN Systematic review with meta-analysis. DATA SOURCES Embase, Medline and PsycINFO were searched from inception until December 2018. Reference lists and Google Scholar were also handsearched. RESULTS Twenty-six papers published from database inception to December 2018 were reviewed. A wide range of psychological and non-psychological outcomes were reported. There was a marked trend for isolated patients to exhibit higher levels of depression, the pooled standardised mean difference being 1.28 (95% CI 0.47 to 2.09) and anxiety 1.45 (95% CI 0.56 to 2.34), although both had high levels of heterogeneity, and worse outcomes for a range of care-related factors but with significant variation. CONCLUSION The review indicates that isolation to contain the risk of infection has negative consequences for segregated patients. Although strength of the evidence is weak, comprising primarily single-centre convenience samples, consistency of the effects may strengthen this conclusion. More research needs to be undertaken to examine this relationship and develop and test interventions to reduce the negative effects of isolation.

Abstract
BACKGROUND Infection control is a critical aspect in the continuum of surgical care. Much of what is outlined in the literature pertains to hospital-based practice, with only recent attention paid to the more austere environments, particularly those faced during humanitarian or combat operations. OBJECTIVE This manuscript provides a brief historical review of the development of infection control practices and further identifies and outlines several aspects necessary to successful program applications in austere environments. RESULTS Hand hygiene remains the simplest form of infection control. Use of alcohol-based hand sanitizer is a logistically reasonable option for most circumstances, mitigating the requirement for clean running water to facilitate more traditional "soap and water" methods of hand disinfection. Environmental decontamination, patient cohorting, and patient isolation based on existing colonization/infection also has demonstrated efficacy in controlling cross-contamination and is feasible in most austere environments. Finally, senior leadership engagement with deliberate planning, antimicrobial stewardship, and vigorous quality and process improvement algorithms have resulted in reduced rates of critical infections in these settings. CONCLUSIONS Basic tenets of infection control can be achieved even in resource-poor environments. Meticulous attention to adhering to these principles, with support from senior medical and operational leadership, facilitates improvements in infection control outcomes. There remains, however, a need for additional robust outcomes data regarding best practices in these environments.

Abstract
Background Infection by multidrug-resistant (MDR) pathogens leads to poor patient outcomes in intensive care units (ICUs). Contact precautions are necessary to reduce the transmission of MDR pathogens. However, the importance of the surrounding environment is not well known. We studied the effects of ICU relocation on MDR respiratory pathogen detection rates and patient outcomes. Methods Patients admitted to the ICU before and after the relocation were retrospectively analyzed. Baseline patient characteristics, types of respiratory pathogens detected, antibiotics used, and patient outcomes were measured. Results A total of 463 adult patients admitted to the ICU, 4 months before and after the relocation, were included. Of them, 234 were admitted to the ICU before the relocation and 229 afterward. Baseline characteristics, including age, sex, and underlying comorbidities, did not differ between the two groups. After the relocation, the incidence rate of MDR respiratory pathogen detection decreased from 90.0 to 68.8 cases per 1,000 patient-days, but that difference was statistically insignificant. The use of colistin was significantly reduced from 53.5 days (95% confidence interval [CI], 20.3 to 86.7 days) to 18.7 days (95% CI, 5.6 to 31.7 days). Furthermore, the duration of hospital stay was significantly reduced from a median of 29 days (interquartile range [IQR], 14 to 50 days) to 21 days (IQR, 11 to 39 days). Conclusions Incidence rates of MDR respiratory pathogen detection were not significantly different before and after ICU relocation. However, ICU relocation could be helpful in reducing the use of antibiotics against MDR pathogens and improving patient outcomes.

Abstract
INTRODUCTION Ulceration of the foot is a common problem among diabetic patients. Infection is a major risk in diabetic foot ulcers (DFU) and many of these are caused by Staphylococcus aureus, in particular meticillin-resistant strains (MRSA). The control and management of MRSA remains a significant challenge and all healthcare organisations in England are required to meet Zero Tolerance Objectives for cases of MRSA bacteraemia (MRSAB). This paper describes a collaborative approach across the health economy to investigate factors contributing to the acquisition of MRSA and MRSAB among DFU patients and make improvements to care to reduce the risk of healthcare-associated infections. METHODS A collaborative approach between acute and community healthcare providers and commissioners was used to conduct Root Cause Analysis and drive improvement to prevent MRSA transmission in DFU patients. RESULTS Screening of all DFU patients was initiated after 6 MRSAB were found to be associated with in DFU. In total 15 patients with the same MRSA antibiogram were identified. Following the implementation of actions focused on isolation, wound management, screening and cleaning no further cases were identified. CONCLUSION This outbreak has demonstrated the value of cross-sector collaboration in investigating HCAI in patients with DFU, improving patient care and reducing the risk of MRSA transmission in these vulnerable patents.

Abstract
BACKGROUND Meticillin-resistant Staphylococcus aureus (MRSA; also known as methicillin-resistant S aureus) is a common hospital-acquired pathogen that increases morbidity, mortality, and healthcare costs. Its control continues to be an unresolved issue in many hospitals worldwide. The evidence base for the effects of the use of gloves, gowns or masks as control measures for MRSA is unclear. OBJECTIVES To assess the effectiveness of wearing gloves, a gown or a mask when contact is anticipated with a hospitalised patient colonised or infected with MRSA, or with the patient's immediate environment. SEARCH METHODS We searched the Specialised Registers of three Cochrane Groups (Wounds Group on 5 June 2015; Effective Practice and Organisation of Care (EPOC) Group on 9 July 2013; and Infectious Diseases Group on 5 January 2009); CENTRAL (The Cochrane Library 2015, Issue 6); DARE, HTA, NHS EED, and the Methodology Register (The Cochrane Library 2015, Issue 6); MEDLINE and MEDLINE In-Process & Other Non-Indexed Citations (1946 to June week 1 2015); EMBASE (1974 to 4 June 2015); Web of Science (WOS) Core Collection (from inception to 7 June 2015); CINAHL (1982 to 5 June 2015); British Nursing Index (1985 to 6 July 2010); and ProQuest Dissertations & Theses Database (1639 to 11 June 2015). We also searched three trials registers (on 6 June 2015), references list of articles, and conference proceedings. We finally contacted relevant individuals for additional studies. SELECTION CRITERIA Studies assessing the effects on MRSA transmission of the use of gloves, gowns or masks by any person in the hospital setting when contact is anticipated with a hospitalised patient colonised or infected with MRSA, or with the patient's immediate environment. We did not assess adverse effects or economic issues associated with these interventions.We considered any comparator to be eligible. With regard to study design, only randomised controlled trials (clustered or not) and the following non-randomised experimental studies were eligible: quasi-randomised controlled trials (clustered or not), non-randomised controlled trials (clustered or not), controlled before-and-after studies, controlled cohort before-after studies, interrupted time series studies (controlled or not), and repeated measures studies. We did not exclude any study on the basis of language or date of publication. DATA COLLECTION AND ANALYSIS Two review authors independently decided on eligibility of the studies. Had any study having been included, two review authors would have extracted data (at least for outcome data) and assessed the risk of bias independently. We would have followed the standard methodological procedures suggested by Cochrane and the Cochrane EPOC Group for assessing risk of bias and analysing the data. MAIN RESULTS We identified no eligible studies for this review, either completed or ongoing. AUTHORS' CONCLUSIONS We found no studies assessing the effects of wearing gloves, gowns or masks for contact with MRSA hospitalised patients, or with their immediate environment, on the transmission of MRSA to patients, hospital staff, patients' caregivers or visitors. This absence of evidence should not be interpreted as evidence of no effect for these interventions. The effects of gloves, gowns and masks in these circumstances have yet to be determined by rigorous experimental studies, such as cluster-randomised trials involving multiple wards or hospitals, or interrupted time series studies.

Cohen CC, Cohen B, Shang J. Effectiveness of contact precautions against multidrug-resistant organism transmission in acute care: a systematic review of the literature. J Hosp Infect 2015; 90:275-84. [PMID: 26051927 PMCID: PMC4486607 DOI: 10.1016/j.jhin.2015.05.003] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2014] [Accepted: 05/05/2015] [Indexed: 11/17/2022]
Abstract
Contact precautions are widely recommended to prevent multidrug-resistant organism (MDRO) transmission. However, conflicting data exist regarding their effectiveness. Prior systematic reviews examined contact precautions as part of a larger bundled approach, limiting ability to understand their effectiveness. The aim of this review was to characterize the effectiveness of contact precautions alone against transmission of any MDRO among adult acute care patients. Directed by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, comprehensive searches of four electronic scientific literature databases were conducted for studies published in English from January 2004 to June 2014. Studies were included if interventional, original research, evaluating contact isolation precautions against MDRO transmission among inpatients. Searches returned 284 studies, six of which were included in the review. These studies measured four different MDROs with one study showing a reduction in transmission. Whereas studies were of high quality regarding outcome operationalization and statistical analyses, overall quality was moderate to low due to poor intervention description, population characterization and potential biases. Where compliance was measured (N = 4), it presented a threat to validity because it included select parts of the intervention, ranged from 21% to 87%, and was significantly different across study phases (N = 2). The poor quality of evidence on this topic continues to limit interpretation of these data. Hence, this conflicting body of literature does not constitute evidence for or against contact precautions. We recommend that researchers consider power calculation, compliance monitoring, non-equivalent concurrent controls when designing future studies on this topic.

Abstract
BACKGROUND Routine microbiologic surveillance is a method of infection control, but its clinical significance in transplant recipients is not known. We analyzed microbiologic data to evaluate the influence of cultured microorganisms between the point of surveillance and infectious episodes in liver transplant recipients. METHODS We performed surveillance culture for sputum and peritoneal fluid in liver transplant recipients from January 2009 to December 2011, at the time of transplantation (T1), 5 days (T2), and 10 days (T3) postoperatively. RESULTS Of the 179 recipients, 32.9% had a positive sputum culture result and 37.4% had a positive peritoneal culture result during surveillance. In the culture surveillance of sputum, 37 organisms were isolated from 35 recipients at T1, and the most common organism was Staphylococcus aureus (n = 13). At T2, 45 organisms were isolated from 39 recipients, including Klebsiella pneumoniae (n = 10), S aureus (n = 8), and Acinetobacter baumannii (n = 6). At T3, 18 organisms were isolated from 15 patients, including Stenotrophomonas maltophilia (n = 5) and K pneumonia (n = 4). In the peritoneal fluid, 11 organisms were isolated from 10 recipients at T1, including Pseudomonas aeruginosa (n = 2) and Enterococcus species (n = 2). At T2, 39 organisms were isolated from 36 recipients, including coagulase-negative Staphylococcus species (CNS; n = 8) and Enterococcus species (n = 7). At T3, 54 organisms were isolated from 51 recipients, including CNS (n = 17) and Candida species (n = 8). Among the 59 patients with positive culture results for sputum surveillance, 16.9% developed pneumonia caused by the same organisms. Among the 67 patients with positive peritoneal fluid culture, 16.4% developed an intra-abdominal infection caused by the same organisms cultured. The recipients with positive surveillance culture had a higher risk of pneumonia (20.3% [12/59] vs 1.6% [2/120]; P < .001) and intra-abdominal infection (31.3% [21/67] vs 18.7% [21/112]; P = .05). CONCLUSIONS Periodic microbiologic surveillance may be useful in the prediction of post-transplantation pneumonia and intra-abdominal infection and could offer a potential target for empirical antimicrobial therapy in cases of infection.

Abstract
BACKGROUND The current data regarding the correlation between the methicillin-resistant Staphylococcus aureus (MRSA) clones carried in the nasal cavity and digestive tract are inadequate. METHODS MRSA strains were isolated from both the feces and nasal swabs of 21 nasal-MRSA carriers ranging from 10 to 104 days of age treated at the neonatal intensive care units of two hospitals. The molecular epidemiological characteristics of the isolates were determined: multilocus sequence types, spa-types, staphylococcal cassette chromosome mec (SCCmec) types, carriage of four exotoxin genes, and genes contained in commercially available kit. RESULTS The feces of all nasal carriers contained MRSA at levels ranging from 4.0 × 10(2) to 2.8 × 10(8) colony forming units/g feces. The MRSA clones isolated from the feces and the nasal swabs of each patient were the same. Four MRSA clones, clonal complex (CC) 8-SCCmec IVl, CC8-SCCmec IVb, CC1-SCCmec IVa and CC5-SCCmec IIa were identified from 21 patients. All CC8-SCCmec IVl strains and one of three CC5-SCCmec IIa strains carried the toxic shock syndrome toxin gene. CONCLUSIONS The feces of tested MRSA carriers contained the same MRSA clones as the nasal isolates in considerable amounts, suggesting that more careful attention should be paid for the handling of excrement in the case of newborn babies or infants than that of adults.

Abstract
Multiple papers have been published regarding the bacterial resistance theme over the last years. A variety of information has reached general and scientific public, daily bringing up data on new resistant microorganisms, new drugs, outbreaks, epidemiological news, resistance gene dissemination, and the lack of information in a particular field has caught our attention: the public health department. Most of researchers, physicians and government employees interpret the public health field as a separate department, not linked to this antibiotic resistance era that we are living nowadays. In this paper we carefully tried to fill in the blanks between public health and the bacteria resistance issue, also considering historical, social, economical and biological problematic that come with this possible pre-antibiotic era.

Abstract
Due to the nature of their underlying illness and treatment regimens, cancer patients are at increased risk of infection. Though the advent and widespread use of anti-infective agents has allowed for the application of ever-greater immune-suppressing therapies with successful treatment of infectious complications, prevention of infection remains the primary goal. The evolutionary changes of microorganisms, whereby resistance to anti-infective therapy is increasingly common, have facilitated a paradigm shift in the field of healthcare epidemiology. No longer is the focus on "control" of infection once established in a healthcare environment. Rather, the emphasis is on prevention of infection before it occurs. The most basic tenet of infection prevention, and the cornerstone of all well-designed infection prevention and control programs, is hand hygiene. The hands of healthcare workers provide a common potential source for transmission of infectious agents, and effective decontamination of the hands reduces the risk of transmission of infectious material to other patients. Once infection is suspected or established; however, implementation of effective control strategies is important to limit the spread of infection within a healthcare environment. This chapter outlines the basic tenets of infection prevention, principles of isolation precautions and control measures, and elements for a successful infection control and prevention program.

Abstract
Background. Infectious diseases seem to be an important and independent risk factor for renal failure, but the underlying mechanism of renal involvement during some kinds of infectious diseases is still unclear, even if the literature data report immunomediated and/or autoimmune mechanisms to explain the pathogenic relationship between the two diseases. In paediatric patients, Chlamydia pneumoniae is a rare cause of renal complications and it may manifest in several ways, mainly involving the respiratory system, even if also renal and glomerulalr complications, have been described. Case Diagnosis/Treatment. Herein we report a case of a 3-year-old child who developed an acute glomerulonephritis that was chronologically, clinically, and biologically related to a previous Chlamydia pneumoniae infection. On our knowledge, in the literature it is the youngest patient with renal involvement during course of Chlamydia pneumoniae infection ever reported. Conclusions. The present case supports the hypothesis of a rather close causal relationship between this infective agent and renal and glomerular symptoms occurred in this child, during an acute episode of respiratory disease.

Abstract
Multidrug-resistant organisms are an established and growing worldwide public health problem and few therapeutic options remain available. The traditional antimicrobials (glycopeptides) for multidrug-resistant Gram-positive infections are declining in efficacy. New drugs that are presently available are linezolid, daptomicin and tigecycline, which have well-defined indications for severe infections, and talavancin, which is under Phase III trial for hospital-acquired pneumonia. Unfortunately the therapies available for multidrug-resistant Gram-negatives, including carbapenem-resistant Pseudomonas aeruginosa, Acinetobacter baumannii and Enterobacteriaceae, are limited to only colistin and tigecycline. Both of these drugs are still not registered for severe infections, such as hospital acquired pneumonia. Consequently, as confirmed by scientific evidence, a multidisciplinary approach is needed. Surveillance, infection control procedures, isolation and antimicrobial stewardship should be implemented to reduce multidrug-resistant organism diffusion.

Abstract
BACKGROUND The aims of our study were analysis of the occurrence of infections by members of the Enterobacteriaceae family in 6 Polish neonatal intensive care units in 2009, their drug resistance, the epidemiology of extended-spectrum β-lactamase (ESBL)-producing strains and the possibility of using modern tools of microbiology diagnosis in infection control, especially for the reduction of antimicrobial resistance. METHODS A prospective surveillance covered 910 newborns. Case patients were defined as neonates with very low birth weight who had clinical signs of septicemia, pneumonia or necrotizing enterocolitis. Early-onset infection was defined as infection diagnosed within 3 days after delivery. RESULTS The incidence of Enterobacteriaceae infections was 2.6/1000 patient-days. The risk of Enterobacteriaceae pneumonia increased with the length of hospitalization (P = 0.0356). The most common pathogen was Escherichia coli (12.4% of all strains, in early-onset infection 18.5%) and Klebsiella spp. (9.1% of all). The ESBL phenotype was found in 37% of isolates, of which 89.3% were producing CTX-M-type, 70.2% TEM-type and 8.5% SHV-type. Epidemic clones were detected in the 2 studied neonatal intensive care units: 6 of the 9 ESBL-positive Enterobacter cloacae and 16 of the 18 ESBL-positive Klebsiella pneumoniae strains were classified into 1 epidemic clone, which showed resistance to penicillin without inhibitors, amoxycillin/clavulanic acid, cephalosporins, aztreoname, aminoglycosides and trimethoprim/sulfamethoxazole. CONCLUSIONS Enterobacteriaceae bacilli are a significant problem in neonatal intensive care units, especially in early-onset infection and for long hospitalized very low birth weight infants. The observed high drug resistance was in large part related to the dominance of epidemic strains as a result of horizontal transmission. The best way to reduce drug resistance would be adequate procedures of isolation and hand hygiene.

Abstract
Isolation or cohorting of infected patients is an old concept. Its purpose is to prevent the transmission of microorganisms from infected or colonized patients to other patients, hospital visitors, and health care workers, who may subsequently transmit them to other patients or become infected or colonized themselves. Because the process of isolating patients is expensive, time-consuming, often uncomfortable for patients and may impede care, it should be implemented only when necessary. Conversely, failure to isolate a patient with multidrug-resistant microorganisms may lead to adverse outcomes, and may ultimately be expensive when one considers the direct costs of an outbreak investigation and the indirect costs of lost productivity. In this review, we argue that contact precautions are essential to control the spread of epidemic and endemic multidrug-resistant microorganisms, and discuss limitations of some available data.

Abstract
Background Methicillin-resistant Staphylococcus aureus (MRSA) is among the most important nosocomial pathogens in the intensive care unit (ICU) worldwide, including Taiwan. Since 1997, our neonatal ICUs (NICUs) had become endemic for MRSA. Methodology/Principal Findings To control MRSA spread in our NICUs, we implemented a series of infection control measures stepwise, including reinforcement of hand hygiene since January 2000, augmentation of aseptic care over the insertion site of central venous catheter since July 2001, introduction of alcohol-based handrubs since April 2003, surveillance culture for MRSA and cohort care for the colonized patients between March 2003 and February 2004, and surveillance culture with subsequent decolonization of MRSA between August 2005 and July 2006. After implementation of these measures, MRSA healthcare-associated infection (HAI) density reduced by 92%, from 5.47 episodes per 1000 patient-days in 1999 to 0.45 episodes per 1000 patient-days in 2006; MRSA bloodstream infection reduced from 40 cases in 1999 to only one case in 2006. Compared to those obtained during the period of surveillance culture without decolonization, both rates of MRSA colonization (8.6% vs. 41%, p<0.001) and infection (1.1% vs. 12%, p<0.001) decreased significantly during the period of surveillance and decolonization. Molecular analysis of the clinical isolates during the study period showed that the endemic clone, which dominated between 1998 and 2005, almost disappeared in 2006, while the community clones increased significantly in 2006–2007. Conclusion/Significance Through infection control measures, MRSA HAIs can be successfully controlled, even in areas with high levels of endemic MRSA infections such as our NICUs.

Abstract
PURPOSE OF REVIEW Attention to patient safety has made hospital infection prevention and control strategies a subject of increasing focus from healthcare personnel, patients and families, accrediting organizations, and government. This review highlights recent literature and new successes in the prevention of healthcare-associated infections in children. RECENT FINDINGS Emerging evidence about risk factors for various healthcare-associated infections in children will help target available adjunctive preventive interventions. Multicenter pediatric collaborative efforts to emphasize best practices have resulted in decreases in infection rates, particularly for central line-associated bloodstream infections. A low prevalence of colonization or infection with multidrug-resistant organisms in hospitalized children, combined with a lack of compelling evidence of effectiveness for active surveillance and decolonization, have made decisions about routine screening challenging. SUMMARY A renewed interest in infection prevention by multiple stakeholders has energized our field and contributed to impressive successes in reducing rates of healthcare-associated infections. Nevertheless, important knowledge gaps remain and an emphasis on funding of high-quality, rigorous studies to answer unresolved questions will be critical to our efforts to further prevent infections for hospitalized children.

Abstract
Given that anti-tuberculosis medication itself has antibacterial activity and that broad-spectrum antibiotics are frequently used, the emergence of multidrug-resistant (MDR) bacteria among patients being treated for tuberculosis (TB) is likely. We used a case-control design to study the clinical predictors of MDR bacterial infection among TB patients. Both cases and controls were selected from among patients who were diagnosed and treated as having TB between 1 January 1996 and 31 August 2006. TB patients with MDR bacterial infection were included as cases and those with non-MDR bacterial infection were included as controls. Multiple logistic regression analysis was performed to elucidate the risk factors for MDR bacterial infection. During the study period 3667 patients were diagnosed with, and treated for, TB. A total of 123 experienced episodes of bacterial infection, of whom 59 (48.0%) were infected by an MDR strain at least once. The presence of chronic renal failure [adjusted odds ratio (OR): 4.96; 95% confidence interval (CI): 1.37-18.01] and the use of antimicrobials other than typical anti-TB drugs within three months (adjusted OR: 4.37; 95% CI: 1.74-10.95) were independent risk factors for MDR bacterial infection. Bacterial infection in TB patients is commonly multidrug resistant. Clinicians should be aware of the possibility of MDR bacterial infection among TB patients with chronic renal failure or recent use of other antimicrobials.

Abstract
In Germany, recommendations on dealing with patients who are colonised with methicillin-resistant S. aureus (MRSA) for the inpatient sector have been published in 1999 by the Commission for Hospital Hygiene and Infection Prevention (KRINKO). Some challenges arise with regard to the practical implementation of the KRINKO recommendations. These challenges do not principally question the benefit of the recommendations but have come into criticism from users. In this commentary the German Society for Hospital Hygiene (DGKH) discusses some controversial issues and adds suggestions for unresolved problems regarding the infection control management of MRSA in healthcare settings.
