Abstract
OBJECTIVE We compared the effectiveness of antibiotic postprescription review and authorization (PPRA) determined by infectious disease (ID) clinical fellows with that of trained general pharmacists. METHODS We conducted a noninferiority cluster-randomized controlled trial in 6 general medical wards at Siriraj Hospital in Bangkok, Thailand. Three wards were randomly assigned to the intervention (ie, the pharmacist PPRA group), and another 3 wards were assigned to the control (ie, the fellow PPRA group). We enrolled all patients in the study wards who received 1 or more doses of the targeted antibiotics: piperacillin/tazobactam, imipenem/cilastatin, and meropenem. The noninferiority margin was 10% for the favorable clinical response and 1.5 defined daily doses (DDDs) for the targeted antibiotics. RESULTS We enrolled 303 patients in the pharmacist PPRA group and 307 patients in the ID fellow PPRA group. The baseline and clinical characteristics were similar in the 2 groups. The difference in the favorable response of patients who received the targeted antibiotics (ie, the pharmacist PPRA group minus the fellow PPRA group) was 5.15% (95% confidence interval [CI], -2.69% to 12.98%); the difference in the DDD of targeted antibiotic use (ie, the pharmacist PPRA group minus the fellow PPRA group) was 0.62 (95% CI, -1.57 to 2.82). We observed no significant difference in the DDD of overall antibiotics, 28-day mortality, 28-day ID-related mortality, favorable microbiological outcome, or antibiotic-associated complications. CONCLUSIONS We confirmed the noninferiority of pharmacist PPRA in terms of favorable clinical response; however, noninferiority in targeted antibiotic consumption could not be established. Therefore, using trained general pharmacists rather than ID clinical fellows could be an alternative in a resource-limited setting.

Abstract
OBJECTIVES To report the extent and components of global efforts in antimicrobial stewardship (AMS) in hospitals. METHODS An Internet-based survey comprising 43 questions was disseminated worldwide in 2012. RESULTS Responses were received from 660 hospitals in 67 countries: Africa, 44; Asia, 50; Europe, 361; North America, 72; Oceania, 30; and South and Central America, 103. National AMS standards existed in 52% of countries, 4% were planning them and 58% had an AMS programme. The main barriers to implementing AMS programmes were perceived to be a lack of funding or personnel, a lack of information technology and prescriber opposition. In hospitals with an existing AMS programme, AMS rounds existed in 64%; 81% restricted antimicrobials (carbapenems, 74.3%; quinolones, 64%; and cephalosporins, 58%); and 85% reported antimicrobial usage, with 55% linking data to resistance rates and 49% linking data to infection rates. Only 20% had electronic prescribing for all patients. A total of 89% of programmes educated their medical, nursing and pharmacy staff on AMS. Of the hospitals, 38% had formally reviewed their AMS programme: reductions were reported by 96% of hospitals for inappropriate prescribing, 86% for broad-spectrum antibiotic use, 80% for expenditure, 71% for healthcare-acquired infections, 65% for length of stay or mortality and 58% for bacterial resistance. CONCLUSIONS The worldwide development and implementation of AMS programmes varies considerably. Our results should inform and encourage the further evaluation of this with a view to promoting a worldwide stewardship framework. The prospective measurement of well-defined outcomes of the impact of these programmes remains a significant challenge.

Abstract
Background In July 2007, the Pharmacy Department at Suburban Hospital implemented an antimicrobial stewardship program (ASP) using existing clinical pharmacy resources that did not include an on-site infectious diseases (ID) pharmacist. Medical staff personnel were supportive of the ASP, but there were no ID physician resources actively dedicated to the program. Remote access to an ID pharmacist was available. Objectives This program evaluated the impact of a pharmacy-driven ASP on cost, antimicrobial utilization, and quality indicators in a community hospital with limited ID professional resources. Methods The tenets of the program were adopted from recommendations in the most current Infectious Diseases Society of America/Society for Healthcare Epidemiology of America antimicrobial stewardship guidelines. Antimicrobial utilization, cost, prospective medication use data, and interventions were tracked using customized spreadsheets. Three years of utilization and cost data were captured to provide a baseline and post implementation comparison. Results Antimicrobial utilization decreased 5.2% compared to baseline ( P < .001) as measured by the defined daily dose (DDD) per 1,000 patient days. The associated cost reduction during the period was 24% compared to baseline ( P < .001), resulting in estimated savings of approximately $290,000. Quality of care indicators improved, and physicians were responsive to daily clinical pharmacist review and pharmacy interventions. Conclusions An ASP can be implemented in a community hospital setting with existing clinical pharmacy resources that do not include an ID specialist dedicated full time to the program. Prospective monitoring of antimicrobial usage resulted in decreased antimicrobial cost and utilization and improvements on key quality of care indicators. Based on this evidence of success, the program continues.

Abstract
Antibiotic stewardship is important to address the problem of antimicrobial resistance, but a practical and sustainable strategy to provide stewardship in a large hospital setting is lacking. We developed a hospital-wide computerised antimicrobial approval system (HCAAS) to guide the use of antimicrobial agents in late 2004 in a 3500-bed medical centre in Taiwan. The objective of this study was to evaluate the impacts of HCAAS on the hospital from 2003 to 2009. Following HCAAS deployment, the gradients of consumption over time during the study period of third- and fourth-generation cephalosporins, fluoroquinolones and glycopeptides fell significantly, whilst that of carbapenems increased. The amount and expenditure of antimicrobial use did not increase with the overall healthcare-associated infection rate, and inpatient mortality rate remained stable with a slight decreasing trend. The rate of meticillin-resistant Staphylococcus aureus started to decline in 2002 and continued after HCAAS deployment. There was an increasing isolation of extended-spectrum β-lactamase-producing Escherichia coli and Klebsiella pneumoniae, presumably leading to the increased use of carbapenems. The isolation rate of Clostridium difficile from patients who developed diarrhoea after antimicrobial therapy did not change over the years, with a mean annual rate of 10.0% after the implementation of HCAAS. HCAAS along with strict infection control measures is necessary to reduce the spread of resistant organisms within the hospital. HCAAS is a sustainable system for providing antibiotic stewardship and exerts a positive impact on the hospital by reducing antimicrobial consumption and expenditure whilst not compromising healthcare quality.

Abstract
BACKGROUND Antibiotic overuse and resistance have become a major threat in the last 2 decades. Many programs tried to optimize antibiotic consumption in the inpatient setting, but the outpatient environment that represents the bulk of antibiotic use has been challenging. Following a significant rise of Clostridium difficile infections, all the health care stakeholders in the province of Quebec, Canada initiated a global education program targeting physicians and pharmacists. METHODS A bundle approach was used; 11 user-friendly guidelines were produced by a group of experts and sent to all physicians and pharmacists in Quebec in January 2005. Downloadable versions of guidelines were posted on a dedicated Web site. They were promoted by professional organizations, universities, and experts during educational events, and there was strong acceptance by the pharmaceutical industry with a willingness to follow the recommendations in their marketing. The Intercontinental Medical Statistics (IMS) database was used to analyze and compare Quebec's total outpatient prescriptions per 1000 inhabitants with those in the other Canadian provinces for 2 time periods: preintervention (January 2003 to December 2004), and postintervention (February 2005 to December 2007). RESULTS In 2004, antibiotic consumption per capita was 23.3% higher in Canada generally than in Quebec. After the guidelines dissemination, the gap between Quebec and the other Canadian provinces increased by 4.1 prescriptions/1000 inhabitants (P = .0002), and the trend persisted 36 months later. Antibiotic costs fell $134.5/1000 inhabitants in Quebec compared with the rest of Canada (P = .054). CONCLUSIONS The implementation of guidelines significantly reduced antibiotic prescriptions in Quebec compared with the rest of the country, and there was a strong trend toward significant cost reduction.

Impact of dose de-escalation and escalation on daptomycin's pharmacodynamics against clinical methicillin-resistant Staphylococcus aureus isolates in an in vitro model. Antimicrob Agents Chemother 2011; 55:2160-5. [PMID: 21321148 PMCID: PMC3088203 DOI: 10.1128/aac.01291-10] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2010] [Accepted: 01/27/2011] [Indexed: 11/20/2022] Open
Abstract
De-escalation and escalation therapeutic strategies are commonly employed by clinicians on the basis of susceptibility results and patient response. Since no in vitro or in vivo data are currently available to support one strategy over the other for daptomycin, we attempted to evaluate the effects of dose escalation and de-escalation on daptomycin activity against methicillin-resistant Staphylococcus aureus (MRSA) isolates using an in vitro pharmacokinetic/pharmacodynamic (PK/PD) model with simulated endocardial vegetations. Three clinical MRSA isolates, including one heterogeneous vancomycin-intermediate S. aureus (hVISA) isolate and one vancomycin-intermediate S. aureus (VISA) isolate, were exposed to daptomycin at 10 or 6 mg/kg of body weight/day for 8 days using a starting inoculum of ∼10(9) CFU/g of vegetations, with dose escalation and de-escalation initiated on the fourth day. Daptomycin MIC values ranged from 0.5 to 1 μg/ml. In the PK/PD model, high-dose daptomycin (10 mg/kg/day) and de-escalation simulation (10 to 6 mg/kg/day) appeared to be the most efficient regimens against the three tested isolates, exhibiting the fastest bactericidal activity (4 to 8 h) compared to that of the standard regimen of 6 mg/kg/day and the escalation therapy of 6 to 10 mg/kg/day. The differences in the numbers of CFU/g observed between dose escalation and de-escalation were significant for the hVISA strain, with the de-escalation simulation exhibiting a better killing effect than the escalation simulation (P<0.024). Although our results need to be carefully considered, the use of high-dose daptomycin up front demonstrated the most efficient activity against the tested isolates. Different therapeutic scenarios including isolates with higher MICs and prolonged drug exposures are warranted to better understand the outcomes of escalation and de-escalation strategies.

Abstract
More than 177 000 potentially preventable healthcare‐associated infections (HAIs) occur per annum in Australia with sizable attributable mortality. Organizational systems to protect against HAI in hospitals in Australia are relatively poorly developed. Awareness and practice of infection control by medical and other healthcare staff are often poor. These lapses in practice create significant risk for patients and staff from HAI. Excessive patient exposure to antimicrobials is another key factor in the emergence of antibiotic‐resistant bacteria and Clostridium difficile infection. Physicians must ensure that their interactions with patients are safe from the infection prevention standpoint. The critical preventative practice is hand hygiene in accord with the World Health Organization 5 moments model. Improving the use of antimicrobials, asepsis and immunization also has great importance. Hospitals should measure and feed back HAI rates to clinical teams. Physicians as leaders, role models and educators play an important part in promoting adherence to safe practices by other staff and students. They are also potentially effective system engineers who can embed safer practices in all elements of patient care and promote essential structural and organizational change. Patients and the public in general are becoming increasingly aware of the risk of infection when entering a hospital and expect their carers to adhere to safe practice. Poor infection control practice will be regarded in a negative light by patients and their families, regardless of any other manifest skills of the practitioner.

Abstract
BACKGROUND AND OBJECTIVE Judicious use of antibiotics is essential considering the growth of antimicrobial resistance and escalating costs in health care. This intervention study used treatment guidelines to improve antibiotic therapy by changing prescribing practice. METHODS A before-after intervention study was performed in a 550-bed tertiary care teaching hospital in Switzerland, with an additional follow-up analysis 1 year later. The pre-intervention phase included chart analysis of current antibiotic use in 100 consecutive patients from the representative medical and surgical wards included in the study. Treatment guidelines were defined, taking into account published guidelines, the local antibacterial sensitivity of the pathogens, and the hospital antibiotic formulary defined by the drug and therapeutics committee. The guidelines were presented to the medical residents on a pocket card. They were informed and educated by the pharmacist (intervention). In the post-intervention phase immediately after the instruction, and in the follow-up phase 1 year later, a prospective analysis of antibiotic prescription was performed by chart review of 100 antibacterial treatments in consecutive patients to detect changes in antibiotic prescribing (treatment) and to determine whether these changes were sustained. RESULTS The pre-intervention review of antibiotic use showed the need for therapy improvements in urinary tract infections (UTI) and hospital-acquired pneumonia (HAP). In the post-intervention phase 100% of UTI were treated as recommended, compared to 30% before the intervention (P < 0.001). The follow-up analysis showed a decrease in guideline adherence to 39% in patients with UTI. Before implementation of the clinical guidelines, HAP was inappropriately treated like community-acquired pneumonia (CAP). Immediately after the intervention, 50% of HAP patients were treated as recommended, and 1 year later (follow-up phase) 56% of HAP patients received the recommended antibiotic medication. This change in prescription practice was significant (P < 0.05). CONCLUSION Antibiotic treatment guidelines for the infections most commonly occurring in hospitalized patients resulted in a significant increase in appropriate antibiotic use. The program was successful in changing prescription practice and achieved a sustained optimization of HAP therapy. Implementing, teaching and monitoring treatment guidelines can have a major impact on patient care.

Abstract
BACKGROUND The problem of antimicrobial resistance requires common strategies at the European level. METHODS We report on an EU initiative fostering antibiotic (AB) stewardship (ABS) in hospitals. RESULTS The project 'ABS International: implementing antibiotic strategies for appropriate use of antibiotics in hospitals in member states of the EU' started in September 2006 in Austria, Belgium, the Czech Republic, Germany, Hungary, Italy, Poland, Slovenia and Slovakia. A training program for national ABS trainers was prepared and standard templates for ABS tools (AB list, guidelines for AB treatment and surgical prophylaxis, and AB-related organization) and valid process measures as well as quality indicators for AB use were developed. Specific ABS tools are being implemented in up to five health care facilities per country. CONCLUSION ABS International is the first EU-funded initiative focusing on the implementation of structural measures in hospitals to promote the prudent use of ABs.
