Abstract
Introduction This study aimed to address the issue of antibiotic prescription processes in an Indian Intensive care unit (ICUs). Materials and methods In a prospective longitudinal study, all adult patients admitted in the ICU for 24 hours or above between 01 June 2020 and 31 July 2021 were screened for any new antibiotic prescription throughout their ICU stay. All new antibiotic prescriptions were assessed for baseline variables at prescription, any modifications during the course, and the outcome of antibiotic prescription. Results A total of 1014 patients fulfilled entry criteria; 59.2 and 7.2% of days they were on a therapeutic and prophylactic antibiotic(s). Patients, who were prescribed therapeutic antibiotic(s), had worse ICU outcomes. A total of 49.5% of patients (502 of 1,014) received a total of 552 new antibiotic prescriptions during their ICU stay. About 92.13% of these prescriptions were empirical and blood or other specimens were sent for culture in 78.81 and 60.04% of instances. A total of 31.7% of episodes were microbiologically proven and were more likely to be prescribed by an ICU consultant. A total of 169 modifications were done in 142 prescription episodes; 73 of them after sensitivity results. Thus, the overall rate of de-escalation was 13.95%. Apart from the negative culture result (36.05%), an important reason for a relatively low rate of de-escalation was the absence of sampling (12.32%). Longer ICU stay before antibiotic prescription, underlying chronic liver disease (CLD), worse organ dysfunction, and septic shock were independently associated with unfavorable treatment outcomes. No such independent association was observed between antibiotic appropriateness and patient outcome. Conclusion Future antibiotic stewardship strategies should address issues of high empirical prescription and poor microbiological sampling hindering the de-escalation process.

Abstract
INTRODUCTION This systematic review aimed to assess antibiotic use in Brazilian hospitals in the 21st century, as well as to understand the different drug utilization metrics adopted to assess the consumption of these drugs. METHODS We systematically reviewed five databases (MEDLINE [Medical Literature Analysis and Retrieval System Online], CENTRAL [The Cochrane Central Register of Controlled Trials], EMBASE® [Excerpta Medica Database], Scopus [Elsevier's abstract and citation database], and LILACS [Literatura Latino-Americana e do Caribe em Ciências da Saúde]) for observational or experimental studies that assessed antibiotic utilization in Brazilian hospitals. The main outcomes were the drug utilization metrics and the consumption of antibiotics. RESULTS We included 23 studies, of which 43.5% were carried out in adult and pediatric care units, 39.1% in adult units, and 17.4% in pediatric units. Regarding the complexity of healthcare, 26.1% of the studies were performed in intensive care units. Two drug utilization metrics were used in these studies: the defined daily dose (DDD) and the percentage of antibiotic prescriptions. The most commonly used antibiotic classes were third-generation cephalosporins, carbapenems, fluoroquinolones, and combinations of penicillins when the DDD was the adopted drug utilization metric. CONCLUSIONS Although few studies have been conducted, existing data indicate a high use of broad-spectrum antibiotics. We found that the lack of standardized antibiotic utilization metrics impaired the mapping of drug consumption at the national level.

Abstract
Abstract
Background
Although inappropriate antibiotics prescribing in hospitals is a key factor in accelerating antibiotic resistance, inadequate data are available about antibiotics prescribing rate and appropriateness. Our study aimed to measure antibiotics prescribing rate, indications, appropriateness and predictors.
Methods
The study was conducted in two public children hospitals (five wards) in Jordan using one-week point prevalence survey to prospectively collect the data. Appropriateness of antibiotics therapy was assessed by a multidisciplinary committee and predictors of inappropriate prescribing were studied through multivariate logistic regression.
Key findings
The overall antibiotics prescribing rate was 75.6% (n = 501/663), where the highest rate of antibiotics prescribing was in the Pediatrics ward (82.2%, n = 222/270). However, the lowest rate was in the Pediatric Intensive Care Unit (30.0%, 9/30). The most common antibiotics classes prescribed were: Beta-lactams (57.5%, n = 492/855). The most common underlying condition for antibiotics prescribing was upper respiratory tract infections (25.5%, n = 128/501) followed by pneumonia (20.6%, n = 103/501). Around half of antibiotics were prescribed upon appropriate decision (49.5%, n = 423/855). However, 22.0% (n = 188/855) of antibiotics were wrongly chosen, and 9.5% (n = 81/855) were wrongly applied. Initially inappropriate decision for prescription occurred in 15.3% (n = 131/855) of antibiotics. Ceftriaxone (OR 3.1; 95% CI 2.6–4.1; P = 0.03) and patients with ≥3 medication orders (OR 2.6; 95% CI 1.7–3.5; P = 0.001) significantly predicted inappropriate antibiotics prescribing.
Conclusions
The incidence of antibiotics prescribing in Jordanian children hospitals was high compared to other countries. Further multi-centric studies are required to enhance the generalisability of results and better develop effective and efficient antibiotic stewardship programmes.

Antimicrob Resist Infect Control 2021; 10:15. [PMID: 33446279 PMCID: PMC7809737 DOI: 10.1186/s13756-021-00887-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Accepted: 01/05/2021] [Indexed: 12/20/2022] Open
Abstract
Background Antibiotic prescribing is common worldwide. There are several original studies about antibiotic prescribing in the healthcare setting of Iran reporting different levels of prescribing. The aim of this systematic review and meta-analysis was to determine the prevalence of antibiotic prescribing in both inpatient and outpatient settings in Iran, an example of a developing country. Methods To identify published studies on antibiotic prescribing, databases such as ISI, Scopus, PubMed, Google Scholar, and Electronic Persian were searched in Iran till January 2020. Eligible studies were those analyzing original data on the prescription and use of antibiotics in outpatient or inpatient settings in Iran. Moreover, all studies that used an intervention to improve antibiotic prescribing were included. The quality of the included studies was assessed using self-administered quality assessment criteria. The meta-analysis of prevalence of antibiotic prescribing was conducted based on the meta-analysis of observational studies in epidemiology guidelines. To calculate pooled rates, the random-effects model was used. Results A total of 54 studies (39 outpatients and 15 inpatients) were included in this study. The median of antibiotic prescribing in the outpatient and inpatient settings accounted for 45.25% and 68.2% of patients, respectively. The results of meta-analysis also showed that the antibiotic prescribing accounted for 45% of prescriptions in outpatient settings and 39.5%, 66%, and 75.3% of patients in all wards, pediatrics wards, and ICU wards of inpatient settings, respectively. The most commonly prescribed antibiotic classes in outpatient settings were penicillins, cephalosporins, and macrolides, while in inpatient settings, these were cephalosporins, penicillins, and carbapenems. There were seven studies using interventions to improve antibiotic prescribing pattern. It should be mentioned that intervention in a study had a statistically significant effect on improving antibiotic prescribing (p < .05). Conclusion Prevalence of antibiotic prescribing in Iran is high. Our findings highlight the need for urgent action to improve prescription practices. It seems that developing a national plan to improve antibiotic prescribing is necessary.

Abstract
Background The burden of bacterial infections is huge and grossly underrepresented in the current health-care system. Inappropriate use of antimicrobial agents (AMAs) poses a potential hazard to patients by causing antibiotic resistance. In addition, the field of antimicrobials is witnessing constant development and introduction of new drugs for which holistic utilization, effectiveness, and side-effects studies are the need of the hour. The current study aims at studying the prescription pattern of AMAs in patients on ventilator and focuses on their prescribing trends. Methodology A prospective, observational study was conducted in Medical Intensive Care Unit (ICU) of a tertiary care hospital of Western India for 6 months. Prescription pattern of AMAs was analyzed using predesigned format. Statistical Analysis Descriptive statistics was used being an observational study. Results Five-hundred and twenty patients who were on ventilator and were prescribed one or more AMAs were enrolled in the study with a mean patient age of 40.7 years. The intended purpose of the use of AMAs was prophylactic in 59% of patients. Empirical therapy was given in 92% of patients. β-lactams group of AMAs along with metronidazole were most frequently used. 73% required concurrent use of two or more AMAs. 9% of the patients required addition or substitution of one or more other AMAs on the basis of culture and sensitivity report or inadequate clinical response and expert opinion. The outcome of therapy with AMAs showed infection was effectively prevented in 34% of the patients. Conclusion This study provides a baseline data for improving the utilization of AMAs in ICU settings by rationalizing their use and also carrying out further studies on prescribing pattern of AMAs in a tertiary care unit.

Abstract
Anaesthesia, Critical Care and Pain Medicine is the journal of the French Society of Anaesthesia and Intensive Care Medicine (Société Francaise d'Anesthésie et de Réanimation), aimed at promoting the French approach to anaesthesiology, critical care and perioperative medicine. Here, the Intensive Care Committee of the French Society of Anaesthesia and Intensive Care Medicine provides an overview of the organisation of the 400 French Intensive Care Units (ICU), which are polyvalent (50%), surgical (20%), or medical (12%). Around 150,000 patients are admitted to these units each year. Law Decrees govern the frame of practices, including architecture, nurse staffing - two nurses for five patients and one nurse-assistant for four patients - and 24/7 medical coverage. The daily cost of ICU hospitalisation is around 1425 €, entirely ensured by the National Health System. The clinical practices are variable but guidelines produced by intensivists are invited to adhere to guidelines available and freely accessible. End-of-life practices are framed by a Law Decree (Claeys Léonetti) aiming at protecting patients against stubbornly and unreasonable cares. The biomedical research plays a critical role in the French ICU, and practices are performed under the supervision of the Jardé Law. An Institutional Research Board approval is required for prospective studies. In conclusion, the French ICU practice is surrounded by a legal frame.

Abstract
Objective.To examine the effect of restricting ciprofloxacin on the resistance of nosocomial gram-negative bacilli, including Pseudomonas aeruginosa, to antipseudomonal carbapenems.Design.Interrupted time-series analysis.Setting.Tertiary care teaching hospital with 11 intensive care and intermediate care units with a total of 295 beds.Patients.All nosocomial isolates of P. aeruginosa.Intervention.Restriction of ciprofloxacin.Results.There was a significant decreasing trend observed in the percentage (P = .0351) and the rate (P = .0006) of isolates of P. aeruginosa that were resistant to antipseudomonal carbapenems following the restriction of ciprofloxacin. There was also a significant decreasing trend observed in the percentage (P = .0017) and the rate (P = .0001) of isolates of ciprofloxacin-resistant P. aeruginosa. The rate of cefepime-resistant P. aeruginosa isolates declined (P = .004 ) but the percentage of cefepime-resistant P. aeruginosa isolates did not change. There were no significant changes observed in the rate or the percentage of piperacillin-tazobactam-resistant P. aeruginosa isolates. There were no significant changes observed in the susceptibilities of nosocomial Enterobacteriaciae or Acinetobacter baumannii isolates that were resistant to carbapenems. Over the study period there was a significant increase in the use of carbapenems (P = .0134); the use of ciprofloxacin decreased significantly (P = .0027). There were no significant changes in the use of piperacillin-tazobactam or cefepime.Conclusion.Restriction of ciprofloxacin was associated with a decreased resistance of P. aeruginosa isolates to antipseudomonal carbapenems and ciprofloxacin in our hospital's intermediate care and intensive care units. There were no changes observed in the susceptibilities of nosocomial Enterobacteriaciae or A. baumannii to carbapenems, despite increased carbapenem use. Reducing ciprofloxacin use may be a means of controlling multidrug-resistant P. aeruginosa.

Abstract
BACKGROUND It is widely acknowledged that the presence of infection is an important outcome determinant for intensive care unit (ICU) patients. In fact, antibiotics are one of the most common therapies administered in the ICU settings. AIM To evaluate the current usage of antibiotics in Latin American ICUs. SUBJECTS AND METHODS A one-day p-oint prevalence study to investigate the patterns of antibiotic was undertaken in 72 Latin American (LA) ICUs. Data was analyzed using the Statistix 8 statistical software, version 2.0 (USA). Results were expressed as proportions. When applicable, two tailed hypothesis testing for difference in proportions was used (Proportion Test); a P value of <0.05 was considered significant. RESULTS Of 704 patients admitted, 359 received antibiotic treatment on the day of the study (51%), of which 167/359 cases (46.5%) were due to hospital-acquired infections. The most frequent infection reorted was nosocomial pneumonia (74/359, 21%). Only in 264/359 patients (73.5%), cultures before starting antibiotic treatment were performed. Thirty-eight percent of the isolated microorganisms were Enterobacteriaceae extended-spectrum β-lactamase-producing, 11% methicillin-resistant Staphylococcus aureus and 10% carbapenems-resistant non-fermentative Gram-negatives. The antibiotics most frequently prescribed were carbapenems (125/359, 35%), alone or in combination with vancomycin or other antibiotic. There were no significant differences in the "restricted" antibiotic prescription (carbapenems, vancomycin, piperacillin-tazobactam, broad-spectrum cephalosporins, fluoroquinolones, tigecycline and linezolid) between patients with APACHE II score at the beginning of the antibiotic treatment <15 [83/114 (72.5%)] and ≥15 [179/245 (73%)] (P = 0.96). Only 29% of the antibiotic treatments were cultured directed (104/359). CONCLUSION Carbapenems (alone or in combination) were the most frequently prescribed antibiotics in LA ICUs. However, the problem of carbapenem resistance in LA requires that physicians improve the use of this class of antibiotics. Our findings show that our web-based method for collection of one-day point prevalence was implemented successfully. However, based on the limitations of the model used, the results of this study must be taken with caution.

Abstract
OBJECTIVES To determine the rate of documented infections and prevalence of antimicrobial use among pediatric patients admitted to the PICU. To assess the appropriateness of antimicrobial prescribing according to clinical and microbiological findings, Infectious Disease Consult recommendations, and formulary guidelines. DESIGN Prospective point prevalence study. SETTING Cardiac and medical-surgical critical care units (CCCU-PICU) in a tertiary care pediatric teaching hospital in Toronto, Canada. PATIENTS All patients admitted to the CCCU-PICU during the week of October 27, 2008 (period A) and February 9, 2009 (period B) were followed until completion of their antimicrobial course(s). Data were collected on infection types and indications, frequency, and types of antimicrobials used. Appropriateness of antimicrobial prescribing was assessed according to predefined criteria by four blinded clinician assessors. MEASUREMENT AND MAIN RESULTS Forty-two of 60 patients (70%) received antimicrobials in period A and 42 of 53 patients (79%) received antimicrobials in period B. Of the patients on antimicrobials, 45% in period A and 52% in period B had a definitive diagnosis of infection. Pneumonia and sepsis were the most common infections in period A, whereas pneumonia and other respiratory tract infections were the most common in period B. Antimicrobials were commonly prescribed for documented infection (38%) during period A and empiric therapy (47%) during period B. Cefazolin, cefuroxime, vancomycin, and gentamicin were the commonly used antimicrobials during both periods. Inappropriate antimicrobial use ranged from 16.7% to 61.9%, depending on assessors and surveillance period. The most common reasons for inappropriate use were overly broad spectrum, wrong dosage, and unwarranted overlap of spectrum. CONCLUSIONS There was a high prevalence of antimicrobial use in CCCU-PICU patients. Because a significant proportion of antimicrobial use was deemed inappropriate, interventions are required to optimize antimicrobial use in critically ill children.

Abstract
BACKGROUND Mortality rates among patients with sepsis, severe sepsis or septic shock are highly variable throughout different regions or services and can be upwards of 50%. Empirical broad-spectrum antimicrobial treatment is aimed at achieving adequate antimicrobial therapy, thus reducing mortality; however, there is a risk that empirical broad-spectrum antimicrobial treatment can expose patients to overuse of antimicrobials. De-escalation has been proposed as a strategy to replace empirical broad-spectrum antimicrobial treatment by using a narrower antimicrobial therapy. This is done by reviewing the patient's microbial culture results and then making changes to the pharmacological agent or discontinuing a pharmacological combination. OBJECTIVES To evaluate the effectiveness and safety of de-escalation antimicrobial treatment for adult patients diagnosed with sepsis, severe sepsis or septic shock caused by any micro-organism. SEARCH METHODS In this updated version, we searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 10); MEDLINE via PubMed (from inception to October 2012); EMBASE (from inception to October 2012); LILACS (from inception to October 2012); Current Controlled Trials; bibliographic references of relevant studies; and specialists in the area. We applied no language restriction. We had previously searched the databases to August 2010. SELECTION CRITERIA We planned to include randomized controlled trials (RCTs) comparing de-escalation (based on culture results) versus standard therapy for adults with sepsis, severe sepsis or septic shock. The primary outcome was mortality (at 28 days, hospital discharge or at the end of the follow-up period). Studies including patients initially treated with an empirical but not adequate antimicrobial therapy were not considered for inclusion. DATA COLLECTION AND ANALYSIS Two authors planned to independently select and extract data and to evaluate methodological quality of all studies. We planned to use relative risk (risk ratio) for dichotomous data and mean difference (MD) for continuous data, with 95% confidence intervals. We planned to use the random-effects statistical model when the estimate effects of two or more studies could be combined in a meta-analysis. MAIN RESULTS Our search strategy retrieved 493 studies. No published RCTs testing de-escalation of antimicrobial treatment for adult patients diagnosed with sepsis, severe sepsis or septic were included in this review. We found one ongoing RCT. AUTHORS' CONCLUSIONS There is no adequate, direct evidence as to whether de-escalation of antimicrobial agents is effective and safe for adults with sepsis, severe sepsis or septic shock. This uncertainty warrants further research via RCTs and the authors are awaiting the results of an ongoing RCT testing the de-escalation of empirical antimicrobial therapy for severe sepsis.

Abstract
Background Antibiotic surveillance is mandatory to optimise antibiotic therapy. Our objectives were to evaluate antibiotic use in our pediatric intensive care unit (PICU) and to implement a simple achievable intervention aimed at improving antibiotic therapy. Method Prospective, 3 months surveillance of antibiotic use on PICU (phase I) and evaluation according to the CDC 12-step campaign with development of an attainable intervention. 3 months surveillance (phase II) after implementation of intervention with comparison of antibiotic use. Results Appropriate antibiotic use for culture-negative infection-like symptoms and targeted therapy for proven infections were the main areas for potential improvement. The intervention was a mandatory checklist requiring indication and recording likelihood of infection at start of antibiotic therapy and a review of the continuing need for therapy at 48 h and 5 days, reasons for continuation and possible target pathogen. The percentage of appropriate empiric antibiotic therapy courses for culture-negative infection-like symptoms increased from 18% (10/53) to 74% (42/57; p<0.0001), duration of therapy <3 days increased from 18% (10/53) to 35% (20/57; p=0.05) and correct targeting of pathogen increased from 58% (7/12) to 83% (20/24; p=0.21). Conclusions Antibiotic surveillance using the CDC 12-step campaign can help to evaluate institutional antibiotic therapy. Development of an attainable intervention using a checklist can show improved antibiotic use with minimal expense.

Abstract
The pharmacokinetics of beta-lactam antibiotics in intensive care patients may be profoundly altered due to the dynamic, unpredictable pathophysiological changes that occur in critical illness. For many drugs, significant increases in the volume of distribution and/or variability in drug clearance are common. When “standard” beta-lactam doses are used, such pharmacokinetic changes can result in subtherapeutic plasma concentrations, treatment failure, and the development of antibiotic resistance. Emerging data support the use of beta-lactam therapeutic drug monitoring (TDM) and individualized dosing to ensure the achievement of pharmacodynamic targets associated with rapid bacterial killing and optimal clinical outcomes. The purpose of this work was to describe the pharmacokinetic variability of beta-lactams in the critically ill and to discuss the potential utility of TDM to optimize antibiotic therapy through a structured literature review of all relevant publications between 1946 and October 2011. Only a few studies have reported the utility of TDM as a tool to improve beta-lactam dosing in critically ill patients. Moreover, there is little agreement between studies on the pharmacodynamic targets required to optimize antibiotic therapy. The impact of TDM on important clinical outcomes also remains to be established. Whereas TDM may be theoretically rational, clinical studies to assess utility in the clinical setting are urgently required.

Abstract
PURPOSE The aim of this work was to study the use of systemic antibacterials and its possible determinants in Hungarian intensive care units (ICUs). METHODS Hospital pharmacy. departments provided package level dispensing data for their corresponding ICU (2006). Data were converted into defined daily doses (DDDs) and expressed as DDD per 100 patient-days and DDD per 100 admissions. Antibiotics were ranked by volume of DDDs, and the agents responsible for 90% of total use (DU90%) were noted. To explore differences and relationships between antibiotic use and antibiotic policy elements/ICU characteristics, the analysis of variances or the Pearson correlation analysis was performed. RESULTS Valid data were obtained for 44 ICUs. Antibiotic use varied widely (from 27.9 to 167.8 DDD per 100 patient-days and from 104.7 to 1784.6 DDD per 100 admissions). In total, 11-34 different antibacterials per ICUs were used, of which, 5-15 were in the DU90% segment. The proportional use of parenteral agents ranged from 46.2 to 98.3%. The mean of overall antibiotic use was highest for penicillins with beta-lactamase inhibitors, followed by quinolones and third-generation cephalosporins. Of the studied factors, only the ICU category (i.e., level of care) showed significant association with total antibacterial use. CONCLUSIONS The striking differences in total antibiotic use and the extensive use of the oral agents in some ICUs may indicate room for improvement. As none of the antibiotic policy elements were accompanied by lower antibiotic use in the pooled analysis, it suggests that--beside the ICU category--other unrevealed factors determine antibiotic use.

Abstract
INTRODUCTION Few studies have addressed the decision-making process of antibiotic therapy (AT) in intensive care unit (ICU) patients. METHODS In a prospective observational study, all consecutive patients admitted over a one-month period (2004) to 41 French surgical (n = 22) or medical/medico-surgical ICUs (n = 19) in 29 teaching university and 12 non-teaching hospitals were screened daily for AT until ICU discharge. We assessed the modalities of initiating AT, reasons for changes and factors associated with in ICU mortality including a specific analysis of a new AT administered on suspicion of a new infection. RESULTS A total of 1,043 patients (61% of the cohort) received antibiotics during their ICU stay. Thirty percent (509) of them received new AT mostly for suspected diagnosis of pneumonia (47%), bacteremia (24%), or intra-abdominal (21%) infections. New AT was prescribed on day shifts (45%) and out-of-hours (55%), mainly by a single senior physician (78%) or by a team decision (17%). This new AT was mainly started at the time of suspicion of infection (71%) and on the results of Gram-stained direct examination (21%). Susceptibility testing was performed in 261 (51%) patients with a new AT. This new AT was judged inappropriate in 58 of these 261 (22%) patients. In ICUs with written protocols for empiric AT (n = 25), new AT prescribed before the availability of culture results (P = 0.003) and out-of-hours (P = 0.04) was more frequently observed than in ICUs without protocols but the appropriateness of AT was not different. In multivariate analysis, the predictive factors of mortality for patients with new AT were absence of protocols for empiric AT (adjusted odds ratio (OR) = 1.64, 95% confidence interval (95%CI): 1.01 to 2.69), age ≥60 (OR = 1.97, 95% CI: 1.19 to 3.26), SAPS II score >38 (OR = 2.78, 95% CI: 1.60 to 4.84), rapidly fatal underlying diseases (OR = 2.91, 95% CI: 1.52 to 5.56), SOFA score ≥6 (OR = 4.48, 95% CI: 2.46 to 8.18). CONCLUSIONS More than 60% of patients received AT during their ICU stay. Half of them received new AT, frequently initiated out-of-hours. In ICUs with written protocols, empiric AT was initiated more rapidly at the time of suspicion of infection and out-of-hours. These results encourage the establishment of local recommendations for empiric AT.

Abstract
BACKGROUND Mortality rates among patients with sepsis, severe sepsis or septic shock ranges from 27% to 54%. Empirical broad-spectrum antimicrobial treatment is aimed at achieving adequate antimicrobial therapy and thus reducing mortality. However, there is a risk that empirical broad-spectrum antimicrobial treatment can expose patients to overuse of antimicrobials. De-escalation has been proposed as a strategy to replace empirical broad-spectrum antimicrobial treatment with a narrower antimicrobial therapy. This is done by either changing the pharmacological agent or discontinuing a pharmacological combination according to the patient's microbial culture results. OBJECTIVES To evaluate the effectiveness and safety of de-escalation antimicrobial treatment for adult patients diagnosed with sepsis, severe sepsis or septic shock caused by any micro-organism. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2008, Issue 8); MEDLINE via PubMed (from inception to August 2010); EMBASE (from inception to August 2010); LILACS (from inception to August 2010); Current Controlled Trials and bibliographic references of relevant studies. We also contacted the main authors in the area. We applied no language restriction. SELECTION CRITERIA We planned to include randomized controlled trials comparing de-escalation (based on culture results) versus standard therapy for adults with sepsis, severe sepsis or septic shock. The primary outcome was mortality (at 28 days, hospital discharge or the end of the follow-up period). Studies including patients initially treated with an empirical but not adequate antimicrobial therapy were not considered for inclusion. DATA COLLECTION AND ANALYSIS Two authors planned to independently select and extract data and evaluate methodological quality of all studies. We planned to use relative risk (risk ratio) for dichotomous data and mean difference (MD) for continuous data, with 95% confidence intervals. We planned to use the random-effects statistical model when the estimate effects of two or more studies could be combined in a meta-analysis. MAIN RESULTS We retrieved 436 references via the search strategy. No randomized controlled trials testing de-escalation antimicrobial treatment for adult patients diagnosed with sepsis, severe sepsis or septic shock could be included in this review. AUTHORS' CONCLUSIONS There is no adequate, direct evidence as to whether de-escalation of antimicrobial agents is effective and safe for adults with sepsis, severe sepsis or septic shock. Therefore, it is not possible to either recommend or not recommend the de-escalation of antimicrobial agents in clinical practice for septic patients. This uncertainty warrants further research via randomized controlled trials or cohort studies.

Dramatic increase of third-generation cephalosporin-resistant E. coli in German intensive care units: secular trends in antibiotic drug use and bacterial resistance, 2001 to 2008. Crit Care 2010; 14:R113. [PMID: 20546564 PMCID: PMC2911759 DOI: 10.1186/cc9062] [Citation(s) in RCA: 123] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2009] [Revised: 12/10/2009] [Accepted: 06/14/2010] [Indexed: 12/02/2022] Open
Abstract
Introduction The objective of the present study was to analyse secular trends in antibiotic consumption and resistance data from a network of 53 intensive care units (ICUs). Methods The study involved prospective unit and laboratory-based surveillance in 53 German ICUs from 2001 through 2008. Data were calculated on the basis of proportions of nonduplicate resistant isolates, resistance densities (that is, the number of resistant isolates of a species per 1,000 patient-days) and an antimicrobial usage density (AD) expressed as daily defined doses (DDD) and normalised per 1,000 patient-days. Results Total mean antibiotic use remained stable over time and amounted to 1,172 DDD/1,000 patient-days (range 531 to 2,471). Carbapenem use almost doubled to an AD of 151 in 2008. Significant increases were also calculated for quinolone (AD of 163 in 2008) and third-generation and fourth-generation cephalosporin use (AD of 117 in 2008). Aminoglycoside consumption decreased substantially (AD of 86 in 2001 and 24 in 2008). Resistance proportions were as follows in 2001 and 2008, respectively: methicillin-resistant Staphylococcus aureus (MRSA) 26% and 20% (P = 0.006; trend test showed a significant decrease), vancomycin-resistant enterococcus (VRE) faecium 2.3% and 8.2% (P = 0.008), third-generation cephalosporin (3GC)-resistant Escherichia. coli 1.2% and 19.7% (P < 0.001), 3GC-resistant Klebsiella pneumoniae 3.8% and 25.5% (P < 0.001), imipenem-resistant Acinetobacter baumannii 1.1% and 4.5% (P = 0.002), and imipenem-resistant K. pneumoniae 0.4% and 1.1%. The resistance densities did not change for MRSA but increased significantly for VRE faecium and 3GC-resistant E. coli and K. pneumoniae. In 2008, the resistance density for MRSA was 3.73, 0.48 for VRE, 1.39 for 3GC-resistant E. coli and 0.82 for K. pneumoniae. Conclusions Although total antibiotic use did not change over time in German ICUs, carbapenem use doubled. This is probably due to the rise in 3GC-resistant E. coli and K. pneumoniae. Increased carbapenem consumption was associated with carbapenem-resistant K. pneumoniae carbapenemase-producing bacteria and imipenem-resistant A. baumannii.

Abstract
Patients in the intensive care unit (ICU) have many risk factors for resistant pathogens such as prolonged length of stay, frequent and broad-spectrum antimicrobial therapy, presence of foreign materials, and proximity with other patients. However, of the risk factors associated with acquisition of resistant pathogens, inappropriate use of antimicrobial agents has been the most implicated. Thus, many health care institutions have adopted antimicrobial stewardship programs (ASPs) as a mechanism to ensure more appropriate antimicrobial use. ASPs can have a significant impact in the ICU, leading to improved antimicrobial use and resistance patterns and decreased infection rates and costs, due to the inherent nature of infections encountered and high and often inappropriate antibiotic utilization in this setting. However, certain challenges exist for ASPs in the ICU including issues with infrastructure and personnel, information technology, the core ASP strategy, patient-specific factors, conversion of intravenous to oral therapy, and dose optimization. The combination of comprehensive infection control (IC) and effective antimicrobial stewardship can prevent the emergence of resistance among microorganisms and may decrease the negative consequences associated with antimicrobial misuse.

Abstract
PURPOSE To report initial results from a European ICU surveillance programme focussing on antibiotic consumption, microbial resistance and infection control. METHODS Thirty-five ICUs participated during 2005. Microbial resistance, antibiotic consumption and infection control stewardship measures were entered locally into a web-application. Results were validated locally, aggregated by project leaders and fed back to support local audit and benchmarking. RESULTS Median (range) antibiotic consumption was 1,254 (range 348-4,992) DDD per 1,000 occupied bed days. The proportion of MRSA was median 11.6% (range 0-100), for ESBL phenotype of E. coli and K. pneumoniae 3.9% (0-80) and 14.3% (0-77.8) respectively, and for carbapenem-resistant P. aeruginosa 22.5% (0-100). Screening on admission for alert pathogens was commonly omitted, and there was a lack of single rooms for isolation. CONCLUSIONS The surveillance programme demonstrated wide variation in antibiotic consumption, microbial resistance and infection control measures. The programme may, by providing rapid access to aggregated results, promote local and regional audit and benchmarking of antibiotic use and infection control practices.

Abstract
Emphysematous pyelonephritis (EPN) is a serious and often life-threatening condition due to a gas-producing and necrotizing infection involving the renal parenchyma and perirenal tissue. The infection is almost exclusively seen in diabetic patients, and the main feature of its presence is finding gas within the kidney. Patients usually present with fever, chills, flank pain, and dysuria. Laboratory testing usually reveals hyperglycemia, leukocytosis, pyuria, an elevated blood urea nitrogen (BUN) level, and high serum creatinine level. Other, nonspecific symptoms such as abdominal pain, nausea, vomiting, and diarrhea can accompany acute pyelonephritis, as found in the reported case. The appropriate management of such serious infection requires combined medical and surgical treatment. In severe infection, nephrectomy should not be delayed. We report a case of EPN in a diabetic patient who presented with gastrointestinal symptoms. A high index of suspicion, coupled with a good imaging study [preferably computed tomography (CT) scanning] of the abdomen can lead to early diagnosis. Appropriate medical and surgical management have resulted in a successful outcome.

Abstract
BACKGROUND Intensive care units (ICUs) are hot zones for emergence and spread of antibiotic resistance because of frequent invasive procedures, antibiotic usage and transmission of bacteria. We report prospective data on antibiotic use and bacterial resistance from 14 academic and non-academic ICUs, participating in the ICU-STRAMA programme 1999-2003. METHODS The quantity of antibiotics delivered to each ICU was calculated as defined daily doses per 1,000 occupied bed days (DDD(1,000)). Specimens for culture were taken on clinical indications and only initial isolates were considered. Species-related breakpoints according to the Swedish Reference Group for Antibiotics were used. Antibiotic resistance was defined as the sum of intermediate and resistant strains. RESULTS Mean antibiotic use increased from 1,245 DDD(1,000) in 1999 to 1,510 DDD(1,000) in 2003 (P = 0.11 for trend). Of Staphylococcus aureus, 0-1.8% were methicillin resistant (MRSA). A presumptive extended spectrum beta-lactamase (ESBL) phenotype was found in <2.4% of Escherichia coli, based on cefotaxime susceptibility, except a peak in 2002 (4.6%). Cefotaxime resistance was found in 2.6-4.9% of Klebsiella spp. Rates of resistance among Enterobacter spp. to cefotaxime (20-33%) and among Pseudomonas aeruginosa to imipenem (22-33%) and ciprofloxacin (5-21%) showed no time trend. CONCLUSION MRSA and cefotaxime-resistant E. coli and Klebsiella spp strains were few despite high total antibiotic consumption. This may be the result of a slow introduction of resistant strains into the ICUs, and good infection control. The cause of imipenem and ciprofloxacin resistance in P. aeruginosa could reflect the increased consumption of these agents plus spread of resistant clones.
