Community pharmacists as antimicrobial resistance stewards: a narrative review on their contributions and challenges in low- and middle-income countries.

Antimicrobial resistance (AMR) is a global public health crisis that impedes the therapeutic effectiveness of available antimicrobial agents. Due to the high burden of infectious diseases and limited resources, especially trained healthcare professionals, low- and middle-income countries (LMICs) are particularly susceptible to the detrimental effects of AMR. Sometimes, as the first and last point of contact for patients seeking treatment for infections, community pharmacists can play a pivotal role in the stewardship required for AMR. This review aims to highlight the contributions made by community pharmacists in LMICs as AMR stewards. The review considers the challenges from the perspectives of limited resources, inadequate training, a lack of policies and regulations, and issues related to patient behavior. Community pharmacists in LMICs could optimize their advocacy contributions by focusing on One Health AMR stewardship. Transformational and actionable patient and population-centric antimicrobial stewardship (AMS) is feasible with the synergy of policymakers and other healthcare providers in the implementation of AMS policies and programs that support community pharmacists in their efforts to promote rational antimicrobial use.

Coming of age: governance challenges in updated AMR national action plans in the EU.

BACKGROUND: National action plans (NAPs) are key instruments for governing antimicrobial resistance (AMR). In Europe, we can now observe many countries updating their NAPs which raise two key research questions; what substantial modifications are states opting for, and how do they wish to address challenges related to AMR governance in a comparative perspective? METHODS: Building on a previous analytical classification, we address these two questions by examining data of updated versions of NAPs in 13 European Union member states covering seventeen elements related to AMR governance. RESULTS: Our results substantiate the large variation with regard to both substantive issues and governance-related matters. Most tellingly, they highlight the growing importance of the One Health approach in updated versions of NAPs. Our analysis also shows that while substantive issues remain important, One Health and the coordination and collaboration issues it entails are becoming more salient in the second or third generation of NAPs. CONCLUSIONS: Updated NAPs suggest that EU member states are becoming increasingly knowledgeable on the causes and consequences of AMR and how it needs to be addressed. The enhanced level of knowledge also leads these countries to address the next set of issues and challenges; to improve domestic and international coordination and collaboration. Thus, the revised NAPs present a noticeable development from substantive issues towards governance issues.

Nurturing Tomorrow's Antibiotic Stewards: An Innovative School Campaign to Combat Antimicrobial Resistance in Delhi.

SUMMARY: Antimicrobials are lifesaving medicines, but their misuse drives antimicrobial resistance. Schools, as educational hubs wield transformative potential in fostering responsible antimicrobial behavior among students and the broader community. An online campaign targeted Delhi schools, training teachers as master trainers who, in turn, educated 359,940 students. Significant pre- to post-test score improvements were observed among teachers (6.98-8.14; P < 0.01) and students (5.20-6.56; P < 0.01). The campaign received excellent feedback (85%), with 966 students participating in the "IDEAthon" competition. While a single session improved knowledge, continuous engagement and activities are imperative for sustained behavioral change in antibiotic usage.

Increasing Guideline-Concordant Durations of Antibiotic Therapy for Acute Otitis Media.

OBJECTIVE: To compare the effectiveness of 2 interventions in improving prescribing of guideline-concordant durations of therapy for acute otitis media (AOM). STUDY DESIGN: This was a quasi-experimental mixed methods analysis that compared a bundled quality improvement intervention consisting of individualized audit and feedback, education, and electronic health record (EHR) changes to an EHR-only intervention. The bundle was implemented in 3 pediatric clinics from January to August 2020 and an EHR-only intervention was implemented in 6 family medicine clinics. The primary outcome measure was prescription of an institutional guideline-concordant 5-day duration of therapy for children ≥2 years of age with uncomplicated AOM. Propensity score matching and differences-in-differences analysis weighted with inverse probability of treatment were completed. Implementation outcomes were assessed using the Reach, Effectiveness, Adoption, Implementation, Maintenance Framework. Balance measures included treatment failure and recurrence. RESULTS: In total, 1017 encounters for AOM were included from February 2019 to August 2020. Guideline-concordant prescribing increased from 14.4% to 63.8% (difference = 49.4%) in clinics that received the EHR-only intervention and from 10.6% to 85.2% (difference = 74.6%) in clinics that received the bundled intervention. In the adjusted analysis, the bundled intervention improved guideline-concordant durations by an additional 26.4% (P < .01) compared with the EHR-only intervention. Providers identified EHR-prescription field changes as the most helpful components. There were no differences in treatment failure or recurrence rates between baseline and either intervention. CONCLUSIONS: Both interventions resulted in improved prescribing of guideline-concordant durations of antibiotics. The bundled intervention improved prescribing more than an EHR-only intervention and was acceptable to providers.

Long-Term Sustainability and Acceptance of Antimicrobial Stewardship in Intensive Care: A Retrospective Cohort Study.

OBJECTIVES: To evaluate long-term uptake of an antimicrobial stewardship audit-and-feedback program along with potential predictors of stewardship suggestions and acceptance across a diverse ICU population. DESIGN: A retrospective cohort study. SETTING: An urban, academic medical institution. PATIENTS: Patients admitted to an ICU who received an antimicrobial stewardship program suggestion between June 2010 and September 2019. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: The antimicrobial stewardship program provided 7,749 antibiotic assessments over the study period and made a suggestion to alter therapy in 2,826 (36%). Factors associated with a higher likelihood of receiving a suggestion to alter therapy included shorter hospital length of stay prior to antimicrobial stewardship program review (odds ratio 1.15 for ≤ 5 d; 95% CI 1.00-1.32), admission to cardiovascular (1.37; 1.06-1.76) or burn surgery (1.88; 1.50-2.36) versus general medicine, and preceding duration of antibiotic use greater than 5 days (1.33; 1.10-1.60). Assessment of aminoglycosides (2.91; 1.85-4.89), carbapenems (1.93; 1.54-2.41), and vancomycin (2.71; 2.19-3.36) versus ceftriaxone was more likely to result in suggestions to alter therapy. The suggestion acceptance rate was 67% (1,895/2,826), which was stable throughout the study period. Admission to a level 3 ICU was associated with higher likelihood of acceptance of suggestions (1.50; 1.14-1.97). Factors associated with lower acceptance rates were admission to burn surgery (0.64; 0.45-0.91), treatment of pneumonia (0.64; 0.42-0.97 for community-acquired and 0.65; 0.44-0.94 for ventilator-acquired), unknown source of infection (0.66; 0.48-0.92), and suggestion types of "narrow spectrum" (0.65; 0.45-0.94), "change formulation of antibiotic" (0.42; 0.27-0.64), or "change agent of therapy" (0.63; 0.40-0.97) versus "change of dose". CONCLUSIONS: An antimicrobial stewardship program implemented over a decade resulted in sustained suggestion and acceptance rates. These findings support the need for a persistent presence of audit-and-feedback over time with more frequent suggestions to alter potentially nephrotoxic agents, increased efforts toward specialized care units, and further work approaching infectious sources that are typically treated without pathogen confirmation and identification.

Evaluating Initial Empiric Therapy for Neutropenic Fever in Vancomycin-Resistant Enterococcus-Colonized Patients.

OBJECTIVES: Vancomycin-resistant enterococcus infections impact mortality in oncology patients. Given the low rate of vancomycin-resistant enterococcus bacteremia, low virulence of vancomycin-resistant enterococcus, and advent of rapid diagnostic systems, vancomycin-resistant enterococcus-directed empiric therapy in vancomycin-resistant enterococcus-colonized patients with neutropenic fever may be unnecessary, promoting increased antimicrobial resistance, drug-related toxicity, and cost. METHODS: Vancomycin-resistant enterococcus-colonized adults admitted for hematopoietic stem cell transplantation or induction therapy for acute leukemia/myeloid sarcoma with neutropenic fever were stratified by vancomycin-resistant enterococcus bacteremia development and empiric vancomycin-resistant enterococcus-directed antimicrobial strategy for first neutropenic fever (Empiric Therapy vs. non-Empiric Therapy). Primary endpoints included vancomycin-resistant enterococcus-related, in-hospital, and 100-day mortality rates. Secondary outcomes included vancomycin-resistant enterococcus bacteremia incidence for first neutropenic fever and the entire hospitalization, length of stay, Clostridioides difficile infection rate, and duration and cost of vancomycin-resistant enterococcus-directed therapy. RESULTS: During first neutropenic fever, 3 of 70 eligible patients (4%) developed vancomycin-resistant enterococcus bacteremia. Although all 3 (100%) were non-Empiric Therapy, no mortality (0%) occurred. Of 67 patients not developing vancomycin-resistant enterococcus bacteremia, 42 (63%) received Empiric Therapy and 25 (37%) non-Empiric Therapy. Empiric Therapy had significantly greater median duration (3 days vs. 0 days; P<.001) and cost ($1604 vs. $0; P<.001) of vancomycin-resistant enterococcus-directed therapy but demonstrated no significant differences in clinical outcomes. CONCLUSION: Available data suggest Empiric Therapy may offer no clinical benefit to this population, regardless of whether vancomycin-resistant enterococcus is identified in blood culture or no pathogen is found. Such an approach may only expose the majority of patients to unnecessary vancomycin-resistant enterococcus-directed therapy and drug-related toxicities while increasing institutional drug and monitoring costs. Even in the few patients developing vancomycin-resistant enterococcus bacteremia, waiting until the organism is identified in culture to start directed therapy likely makes no difference in mortality. This lack of benefit warrants consideration to potentially omit empiric vancomycin-resistant enterococcus-directed therapy in first neutropenic fever in many of these patients.

Antimicrobial stewardship: can we add pharmacovigilance networks to the toolbox?

BACKGROUND: Antimicrobial resistance (AMR) is no longer an expected upcoming threat; it has become a real public health concern, challenging all existing control tools, requiring multidisciplinary innovative solutions. Antimicrobial stewardship (AMS) programs require a set of tools and skills which can be put to service by health systems. However, there is an immense capacity gap between health systems in developed countries compared to developing ones. Systems in developed countries can rely on well-established laboratory services that can carry out microbial cultures and drug susceptibility tests. For many low- and middle-income countries (LMICs) with limited laboratory resources, it will take time and long-term investments to have systems that can timely and reliably perform laboratory-based AMR monitoring. In the meantime, we must explore the possibility of using other indirect measures that can provide estimates of the growing burden of AMR in settings with weak laboratory capacity. OBJECTIVES: In this point of view, we describe the potential contribution of the global pharmacovigilance (PV) networkers in the process of mapping and estimating the AMR burden in settings with less laboratory coverage and capacity, within the framework of AMS. CONCLUSION: The heavy toll caused by AMR will not be brought down by a singular interventional approach, it will require a multidisciplinary and multifaceted set of strategies. Closing the laboratory capacity gap will require tremendous long-term investments, but the AMR data scarcity is a question that cannot wait any longer. The global pharmacovigilance network is a robust scientific community with experience in tracking suspected adverse events caused by new and old medicinal products. As AMR becomes a global health issue, AMS programs need all available tools to address resistance data scarcity and inform appropriate of antimicrobials. The solid global pharmacovigilance infrastructure could play an important role in countries with limited laboratory coverage and capacity.

Successfully controlling the incidence of multidrug-resistant Pseudomonas aeruginosa through antibiotic stewardship and infection control programmes at a Chinese university hospital.

WHAT IS KNOWN AND OBJECTIVE: The purpose of this study was to investigate the effect of imposing infection control programmes (ICPs) and antimicrobial stewardship (AMS) by monitoring the antimicrobial resistance of Pseudomonas aeruginosa. METHODS: Antimicrobial susceptibility testing was performed in accordance with the Clinical and Laboratory Standards Institute and European Committee on Antimicrobial Susceptibility Testing guidelines. ICPs and AMS were initiated at the Fourth Hospital from 2013 to 2018. RESULTS AND DISCUSSION: A total of 2,886 P. aeruginosa isolates were assessed. The antimicrobial resistance trends of the P. aeruginosa strains improved after the intervention measures. Multidrug-resistant (MDR) and extensively drug-resistant (XDR) P. aeruginosa contributed to 18.5% and 3.5% of the total P. aeruginosa strains, respectively. Colistin was the most effective antibiotic against 97.6% of XDR-P. aeruginosa and 99.41% of MDR-P. aeruginosa. The consumption of alcohol-based hand gel (ABHG) increased from 0.6 L to 10.8 L per 1,000 patient-days (PD) (p = 0.005). The yearly consumption of antibiotics decreased from 45 to 37.5 defined daily doses (DDD) per 1,000 PD(p = 0.04). After 2013, the incidence rate of MDR-P. aeruginosa showed a significant decrease from 22% to 14.1% (p = 0.04), and XDR-P. aeruginosa decreased from 5.8% to 0.9%. The use of ABHG was negatively related to MDR-P. aeruginosa morbidity (r = -0.86; p = 0.021). The consumption of antibiotics was positively related to MDR-P. aeruginosa morbidity (r = 0.86; p = 0.021). WHAT IS NEW AND CONCLUSION: Successful control of MDR-P. aeruginosa resistance was achieved by imposing comprehensive ICPs and AMS.

Impact and barriers of a pharmacist-led practice with computerized reminders on intravenous to oral antibiotic conversion for community-acquired pneumonia inpatients.

WHAT IS KNOWN AND OBJECTIVE: Intravenous to oral (IV-PO) antibiotic conversion, one of the critical elements in antimicrobial stewardship (AMS), is not well implemented in China. Studies on the strategy to apply the IV-PO conversion are needed. Our objective was to evaluate the impact and its barriers of a pharmacist-led practice with computerized reminders on IV-PO antibiotic conversion for community-acquired pneumonia (CAP) inpatients. METHOD: This was a retrospective, observational pre- and post-intervention study. Interventions were introduced in 2 sequential 12-month phases: Phase 1: pharmacists implemented the conventional practice of reviewing patient charts and medication records every 24 h and verbally informed the prescribers on eligible IV-PO conversions; Phase 2: pharmacists implemented a new intervention practice to inform the prescribers with a computerized reminder in electronic medical record system on eligible IV-PO conversions. MAIN OUTCOME MEASURES: The primary outcome was the proportion of patients who converted to oral therapy on the day patients were eligible for the conversion. The secondary outcomes were length of IV antibiotic therapy days, total length of antibiotic therapy days and length of hospital stay. RESULTS: A total of 524 patients were studied (256 in phase 1 and 268 in phase 2). The proportion of patients who converted to oral therapy on the day patients were eligible for the conversion was significantly increased from 34.77% (89/256) in phase 1 to 62.69% (168/268) in phase 2 (p < 0.05). Length of IV antibiotic therapy days in phase 2 was shortened by 1.23 days, which was 5.52 days compared to 6.75 days in phase 1 (p < 0.05). Total length of antibiotic therapy days was 12.05 days in Phase 1, compared to 10.75 days in phase 2 (p > 0.05). Length of hospital stay for patients in phase 2 was significantly shorter, with a difference of 1.38 days (6.02 days vs. 7.40 days, p < 0.05). The most common barrier of not converting IV-PO was the presence of co-morbidity. CONCLUSION: The pharmacist-led IV-PO antibiotic conversion practice with computerized reminders was successful and feasible in Chinese hospitals. More IV-PO intervention studies in patients with other infections are needed in the future.

COVID-19 and the potential long-term impact on antimicrobial resistance.

The emergence of the Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) has required an unprecedented response to control the spread of the infection and protect the most vulnerable within society. Whilst the pandemic has focused society on the threat of emerging infections and hand hygiene, certain infection control and antimicrobial stewardship policies may have to be relaxed. It is unclear whether the unintended consequences of these changes will have a net-positive or -negative impact on rates of antimicrobial resistance. Whilst the urgent focus must be on controlling this pandemic, sustained efforts to address the longer-term global threat of antimicrobial resistance should not be overlooked.

Antimicrobial Stewardship in Hematological Patients at the intensive care unit: a global cross-sectional survey from the Nine-i Investigators Network.

A global cross-sectional survey was performed to gather data on the current treatment of infections caused by multidrug-resistant (MDR) bacteria among hematological patients admitted to ICUs worldwide. The survey was performed in April 2019 using an electronic platform (SurveyMonkey®) being distributed among 83 physicians and completed by 48 (57.8%) responders. ESBL Enterobacteriaceae, carbapenem-resistant K. pneumoniae and carbapenem-resistant P. aeruginosa were the main concerns. Previous MDR infection (34% of responders), MDR colonization (20%) and previous antibiotic exposure within the last 3 months (20.5%) were considered the most relevant risk factors of bloodstream infection (BSI) due to MDR bacteria. In 48.8% of the ICUs, there was no antimicrobial stewardship (AMS) team focused on hematological patients. Updates on local epidemiology of MDR pathogens were provided in 98% of the centers, using phone or verbal communications (56.1% and 53.7%, respectively). In presence of febrile neutropenia, initial therapy consisted of anti-Gram-negative plus anti-Gram-positive antibiotics for 41% of participants. Antibiotic de-escalation and/or discontinuation of therapy were considered as a promising strategy for the prevention of MDR development (32.4%). Factors associated with antibiotic de-escalation were clinical improvement (43.6%) and neutrophil count recovery (12.8%). Infectious Disease consultation and AMS interventions were not determining factors for de-escalation decisions (more than 50% of responders). Infection control and educational programs were valued as necessary measures for implementation by ICU practitioners. These findings should guide future efforts on collaborative team working, improving compliance with adequate treatment protocols, implementing antimicrobial stewardship programs in critically ill hematological patients, and educational activities.

Hospital physicians' experiences with procalcitonin - implications for antimicrobial stewardship; a qualitative study.

BACKGROUND: Procalcitonin is an inflammatory biomarker that is sensitive for bacterial infections and a promising clinical decision aid in antimicrobial stewardship programs. However, there are few studies of physicians' experiences concerning the use of PCT. The objective of this study was to investigate whether hospital physicians' experience with procalcitonin after 18 months of use can inform the PCT implementation in antimicrobial stewardship programs. MATERIALS/METHODS: We deployed a qualitative approach using semi-structured interviews with 14 hospital physicians who had experience with procalcitonin in clinical practice. Interviews were audio-taped, transcribed verbatim and analysed using thematic analysis. RESULTS: Physicians reported a knowledge gap, which made them uncertain about the appropriate procalcitonin use, interpretation, and trustworthiness. Simultaneously, the physicians experienced procalcitonin as a useful clinical decision aid but emphasised that their clinical evaluation of the patient was the most important factor when deciding on antibiotic treatment. CONCLUSIONS: Procalcitonin was regarded a helpful clinical tool, but the physicians called for more knowledge about its appropriate uses. Active implementation of unambiguous procalcitonin algorithms and physician education may enhance the utility of the test as an antimicrobial stewardship adjunct.

Control of antimicrobial resistance in Iran: the role of international factors.

BACKGROUND: Antimicrobial resistance (AMR) is currently causing various challenges for all countries around the world. Accordingly, the WHO is placing a great emphasis on the global partnership and allinaces to drive countries towards developing policy guidances and a strategic framework for AMR contatiment. This study thus seeks to elaborate on the international factors underlying AMR management in Iran. METHODS: Semi-structured interviews were conducted with managers from the Ministry of health (n = 14), Iran veterinary organization (n = 4), the national professional associations (n = 3) and researchers (n = 3), between November 2018 and July 2019. Participants were selected using purposeful and snowball sampling. Interviews were recorded and transcribed verbatim and were subsequently coded and analyzed thematically using MAXQDA software (V.18) and reported. RESULTS: International enabling and predisposing factors were identified in relation to the AMR control in the country. Enabling factors included knowledge transfer, facilitation in policy agenda setting, formulation and implementaion process, and AMR monitoring. Predisposing factors, alternatively, encompassed the migration of infectious patients, trafficking of medicine and livestock from neighboring countries, and the imposed sanctions. CONCLUSION: Nowadays, AMR is taken cognizance of as a global challenge, thus to be addressed effectively, needs an international consensus more than ever. This harmony would not certainly underrate national efforts, but instead, is needed to reinforce such efforts through e.g. technical and financial assistance. It is suggested for policymakers to use all available political and legal means such as health diplomacy to establish humanitarian channels in order to enhance global convention and remove possible barriers as the sanctions and reduce their adverse consequences for AMR control.

Promoting rational antibiotic prescribing for non-complicated infections: understanding social influence in primary care networks in Germany.

BACKGROUND: Primary care networks in Germany are formalized regional collaborations of physicians and other healthcare providers. Common goals are optimized healthcare processes and services for patients, enhanced communication, agency for professional concerns and strengthened economic power. In the ARena study (Sustainable reduction of antibiotic-induced antimicrobial resistance), 14 primary care networks in two federal German states aimed to promote appropriate antibiotics use for acute non-complicated infections by fostering awareness and understanding. Factors related to the role of primary care networks were to be identified. METHODS: For this study, audio-recorded telephone interviews were conducted with physicians, non-physician health professionals and stakeholder representatives. Pseudonymized verbatim transcripts were coded using thematic analysis. In-depth analysis was based on the inductive categories 'social support', 'social learning', 'social normative pressures' and 'social contagion' to reflect social influence processes. Data generated through a survey with physicians and non-physician health professionals were analyzed descriptively to foster understanding of the networks' potential impact on antibiotic prescribing. RESULTS: Social influence processes proved to be relevant regarding knowledge transfer, manifestation of best-practice care and self-reflection. Peer communication was seen as a great asset, the main reason for membership and affirmative for own perspectives. All interviewed physicians (n = 27) considered their network to be a strong support factor for daily routines, introduction of new routines, and continuity of care. They utilized network-offered training programs focusing on best practice guideline-oriented use of antibiotics and considered their networks supportive in dealing with patient expectations. A shared attitude combined with ARena intervention components facilitated reflective management of antibiotic prescribing. Non-physician health professionals (n = 11) also valued network peer exchange. They assumed their employers joined networks to offer improved and continuous care. Stakeholders (n = 7) expected networks and their members to be drivers for care optimization. CONCLUSION: Primary care networks play a crucial role in providing a platform for professional peer exchange, social support and reassurance. With regards to their impact on antibiotic prescribing for acute non-complicated infections, networks seem to facilitate and amplify quality improvement programs by providing a platform for refreshing awareness, knowledge and self-reflection among care providers. They are well suited to promote a rational use of antibiotics. TRIAL REGISTRATION: ISRCTN, ISRCTN58150046. Registered 24 August 2017.

Antimicrobial stewardship in the primary care setting: from dream to reality?

BACKGROUND: Clinicians who work in primary care are potentially the most influential healthcare professionals to address the problem of antibiotic resistance because this is where most antibiotics are prescribed. Despite a number of evidence based interventions targeting the management of community infections, the inappropriate antibiotic prescribing rates remain high. DISCUSSION: The question is how can appropriate prescribing of antibiotics through the use of Antimicrobial Stewardship (AMS) programs be successfully implemented in primary care. We discuss that a top-down approach utilising a combination of strategies to ensure the sustainable implementation and uptake of AMS interventions in the community is necessary to support clinicians and ensure a robust implementation of AMS in primary care. Specifically, we recommend a national accreditation standard linked to the framework of Core Elements of Outpatient Antibiotic Stewardship, supported by resources to fund the implementation of AMS interventions that are connected to quality improvement initiatives. This article debates how this can be achieved. The paper highlights that in order to support the sustainable uptake of AMS programs in primary care, an approach similar to the hospital and post-acute care settings needs to be adopted, utilising a combination of behavioural and regulatory processes supported by sustainable funding. Without these strategies the problem of inappropriate antibiotic prescribing will not be adequately addressed in the community and the successful implementation and uptake of AMS programs will remain a dream.

Do Neonatal Infections Require a Positive Blood Culture?

Neonatal sepsis is a major cause of worldwide morbidity and mortality. Blood cultures are considered the gold standard for diagnosis, but results are often delayed for 24 to 48 hours, and sensitivity, although improved by modern techniques, such as automated blood cultures, is variable and affected by the bacterial load. For these reasons, empiric antibiotics are frequently administered to avoid potential devastating consequences of untreated sepsis. Unnecessary antibiotic treatment has been associated with increased mortality and other adverse outcomes; therefore, antibiotics should be discontinued as soon as sepsis has been ruled out. Negative cultures pose a challenge to clinicians, who must distinguish between real sepsis and sepsis-like conditions (noninfectious or viral) which do not require antibiotics. Focal infections with negative blood cultures do require antibiotic treatment. Ultra-low bacteremia, primary or secondary to recent antibiotic exposure, is often associated with negative cultures, and some consider a short course of empiric antibiotics sufficient for clearing of bacteremia. Biomarkers and molecular methods based on polymerase chain reaction are important add-ons to clinical signs or symptoms for establishing the diagnosis of sepsis. Other promising future potential adjuvants are metabolomics. Antibiotic stewardship should be implemented to avoid or discontinue unnecessary treatment. Prevention of infection still remains the most important step for dealing with neonatal sepsis. KEY POINTS: · Blood cultures are the gold standard diagnosis of neonatal sepsis but sometimes may be negative.. · Other bacterial, viral, and noninfectious conditions may mimic sepsis, prompting initiation of empiric antibiotic treatments.. · Since a definition of neonatal sepsis is lacking, recognizing real septic episodes may be challenging..

A ROADMAP Plan to Address Research Needs for Gonococcal Antimicrobial Resistance in China.

Gonococcal antimicrobial resistance (AMR) has become a global threat significantly hampering the control of gonorrhea. Many socioeconomic, biological, behavioral, and programmatic factors have played an important role in driving the emergence, transmission and spread of gonococcal AMR. However, research to address these scientific and programmatic questions is limited in China. Here we propose a ROADMAP (acronym for resistance surveillance, outcomes due to AMR, antibiotic stewardship and application, diagnostic tools, mechanisms of AMR, antimicrobial assessment, and population pharmacokinetics and pharmacodynamics) plan for expanding interdisciplinary collaborations to address the research needs in China.

Long-Term Effects of Phased Implementation of Antimicrobial Stewardship in Academic ICUs: 2007-2015.

OBJECTIVES: Antimicrobial stewardship is advocated to reduce antimicrobial resistance in ICUs by reducing unnecessary antimicrobial consumption. Evidence has been limited to short, single-center studies. We evaluated whether antimicrobial stewardship in ICUs could reduce antimicrobial consumption and costs. DESIGN: We conducted a phased, multisite cohort study of a quality improvement initiative. SETTING: Antimicrobial stewardship was implemented in four academic ICUs in Toronto, Canada beginning in February 2009 and ending in July 2012. PATIENTS: All patients admitted to each ICU from January 1, 2007, to December 31, 2015, were included. INTERVENTIONS: Antimicrobial stewardship was delivered using in-person coaching by pharmacists and physicians three to five times weekly, and supplemented with unit-based performance reports. Total monthly antimicrobial consumption (measured by defined daily doses/100 patient-days) and costs (Canadian dollars/100 patient-days) before and after antimicrobial stewardship implementation were measured. MEASUREMENTS AND MAIN RESULTS: A total of 239,123 patient-days (57,195 patients) were analyzed, with 148,832 patient-days following introduction of antimicrobial stewardship. Antibacterial use decreased from 120.90 to 110.50 defined daily dose/100 patient-days following introduction of antimicrobial stewardship (adjusted intervention effect -12.12 defined daily dose/100 patient-days; 95% CI, -16.75 to -7.49; p < 0.001) and total antifungal use decreased from 30.53 to 27.37 defined daily doses/100 patient-days (adjusted intervention effect -3.16 defined daily dose/100 patient-days; 95% CI, -8.33 to 0.04; p = 0.05). Monthly antimicrobial costs decreased from $3195.56 to $1998.59 (adjusted intervention effect -$642.35; 95% CI, -$905.85 to -$378.84; p < 0.001) and total antifungal costs were unchanged from $1771.86 to $2027.54 (adjusted intervention effect -$355.27; 95% CI, -$837.88 to $127.33; p = 0.15). Mortality remained unchanged, with no consistent effects on antimicrobial resistance and candidemia. CONCLUSIONS: Antimicrobial stewardship in ICUs with coaching plus audit and feedback is associated with sustained improvements in antimicrobial consumption and cost. ICUs with high antimicrobial consumption or expenditure should consider implementing antimicrobial stewardship programs.

Adaptation of the WHO Essential Medicines List for national antibiotic stewardship policy in England: being AWaRe.

OBJECTIVES: Appropriate use of and access to antimicrobials are key priorities of global strategies to combat antimicrobial resistance (AMR). The WHO recently classified key antibiotics into three categories (AWaRe) to improve access (Access), monitor important antibiotics (Watch) and preserve effectiveness of 'last resort' antibiotics (Reserve). This classification was assessed for antibiotic stewardship and quality improvement in English hospitals. METHODS: Using an expert elicitation exercise, antibiotics used in England but not included in the WHO AWaRe index were added to an appropriate category following a workshop consensus exercise with national experts. The methodology was tested using national antibiotic prescribing data and presented by primary and secondary care. RESULTS: In 2016, 46/108 antibiotics included within the WHO AWaRe index were routinely used in England and an additional 25 antibiotics also commonly used in England were not included in the WHO AWaRe index. WHO AWaRe-excluded and -included antibiotics were reviewed and reclassified according to the England-adapted AWaRE index with the justification by experts for each addition or alteration. Applying the England-adapted AWaRe index, Access antibiotics accounted for the majority (60.9%) of prescribing, followed by Watch (37.9%) and Reserve (0.8%); 0.4% of antibiotics remained unclassified. There was unexplained 2-fold variation in prescribing between hospitals within each AWaRe category, highlighting the potential for quality improvement. CONCLUSIONS: We have adapted the WHO AWaRe index to create a specific index for England. The AWaRe index provides high-level understanding of antibiotic prescribing. Subsequent to this process the England AWaRe index is now embedded into national antibiotic stewardship policy and incentivized quality improvement schemes.
