OBJECTIVE:  We aimed to reduce our monthly antibiotic usage rate (AUR, days of treatment per 1,000 patient-days) in the neonatal intensive care unit (NICU) from a baseline of 330 (July 2015-April 2016) to 200 by December 2018. STUDY DESIGN:  We identified three key drivers as follows: (1) engaging NICU charge nurses, (2) challenging the culture of culture-negative sepsis, and (3) reducing central-line associated bloodstream infections (CLABSI). Our main outcome was AUR...

Introduction. Resistance against macrolide antibiotics in Mycoplasma pneumoniae is becoming non-negligible in terms of both appropriate therapy and diagnostic stewardship. Molecular methods have attractive features for the identification of Mycoplasma pneumoniae as well as its resistance-associated mutations of 23S ribosomal RNA (rRNA). Hypothesis/Gap Statement. The automated molecular diagnostic sytem can identify macrolide-resistant M. pneumoniae . Aim. To assess the performance of an automated molecular diagnostic system, GENECUBE Mycoplasma, in the detection of macrolide resistance-associated mutations...

The coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread worldwide. Bacterial co-infections are associated with unfavourable outcomes in respiratory viral infections; however, microbiological and antibiotic data related to COVID-19 are sparse. Adequate use of antibiotics in line with antibiotic stewardship (ABS) principles is warranted during the pandemic. We performed a retrospective study of clinical and microbiological characteristics of 140 COVID-19 patients admitted between February and April 2020 to a German University hospital, with a focus on bacterial co-infections and antimicrobial therapy...

Antibiotic overprescribing is a global challenge contributing to rising levels of antibiotic resistance and mortality. We test a novel approach to antibiotic stewardship. Capitalising on the concept of "wisdom of crowds", which states that a group's collective judgement often outperforms the average individual, we test whether pooling treatment durations recommended by different prescribers can improve antibiotic prescribing. Using international survey data from 787 expert antibiotic prescribers, we run computer simulations to test the performance of the wisdom of crowds by comparing three data aggregation rules across different clinical cases and group sizes...

Artificial intelligence (AI) is a field of science and engineering concerned with the computational understanding of what is commonly called intelligent behavior. AI is extremely useful in many human activities including medicine. The aim of our narrative review is to show the potential role of AI in fighting antimicrobial resistance in pediatric patients. We searched for PubMed articles published from April 2010 to April 2020 containing the keywords "artificial intelligence", "machine learning", "antimicrobial resistance", "antimicrobial stewardship", "pediatric", and "children", and we described the different strategies for the application of AI in these fields...

Antibiotic use is a key driver of antibiotic resistance. Understanding the quantitative association between antibiotic use and resulting resistance is important for predicting future rates of antibiotic resistance and for designing antibiotic stewardship policy. However, the use-resistance association is complicated by "spillover," in which one population's level of antibiotic use affects another population's level of resistance via the transmission of bacteria between those populations. Spillover is known to have effects at the level of families and hospitals, but it is unclear if spillover is relevant at larger scales...

OBJECTIVE: Assess the effectiveness of a multifaceted stewardship intervention to reduce frequency and duration of inappropriate antibiotic use for emergency department (ED) patients with skin and soft tissue infections (SSTI). We hypothesized the antibiotic stewardship program would reduce antibiotic duration and improve guideline adherence in discharged SSTI patients. DESIGN: Nonrandomized controlled trial. SETTING: Academic EDs (intervention site and control site)...

BACKGROUND: The frameworks used by Health Technology Assessment (HTA) agencies for value assessment of medicines aim to optimize healthcare resource allocation. However, they may not be effective at capturing the value of antimicrobial drugs. OBJECTIVES: To analyze stakeholder perceptions regarding how antimicrobials are assessed for value for reimbursement purposes and how the Australian HTA framework accommodates the unique attributes of antimicrobials in cost-effectiveness evaluation...

Background: Verigene Blood-Culture Gram-Negative is a rapid diagnostic test (RDT) that detects gram-negatives (GNs) and resistance within hours from gram stain. The majority of the data support the use of RDTs with antimicrobial stewardship (AMS) intervention in gram-positive bloodstream infection (BSI). Less is known about GN BSI. Methods: This was a retrospective quasi-experimental (nonrandomized) study of adult patients with RDT-target GN BSI comparing patients pre-RDT/AMS vs post-RDT/pre-AMS vs post-RDT/AMS...

Maximum antibiotic usage within hospitals occurs in critical care areas. Reasons for this usage are the moribund state of patients, invasive devices, and protocol based necessity for empiric antibiotic initiation in most critical conditions. Although unavoidable, prudent use of antibiotics (empiric and therapeutic) should be tailored based on national or if available, unit-based hospital antibiogram. This forms the footstool of every antibiotic policy formulated at tertiary care hospitals. Strict adherence to antibiotic policy formulated based on hospital antibiogram largely benefits patients and hospital-wide antimicrobial stewardship is ensured...

This article summarizes the literature describing how antimicrobial stewardship and telemedicine interventions affect antimicrobial resistance. Discussion includes why we need stewardship, how to collaborate with team members, and the evidence of stewardship's and telemedicine's impact on resistance.

Introduction : Eradication of Helicobacter pylori (H. pylori) becomes more challenging due to increasing antimicrobial resistance. Consequently, the performance of clarithromycin-containing triple therapies is now declining to unacceptable levels and should be abandoned unless a prior susceptibility test precludes clarithromycin resistance. Areas covered : This review summarizes updated evidence concerning new and advancing pharmacotherapy options for H. pylori eradication. Expert opinion : Due to the declining efficacy of legacy triple therapies, most guidelines recommend bismuth quadruple therapy as the best initial empiric treatment...

BACKGROUND: Inappropriate antibiotics use is a global threat. Clinical microbiology laboratory testing can support optimal antibiotic prescribing for many conditions. The purpose of this study was to characterize antibiotic usage in the context of treatment of uncomplicated urinary tract infection (UTI) received through a Ghanaian Accident & Emergency, which found high rates of improper usage. METHODS: A prospective cohort study recruited patients ≥18 years of age who were admitted to a large Ghanaian teaching hospital with suspected UTI...

Pharyngitis (also known as sore throat) is a common, predominately viral, self-limiting condition which can be symptomatically managed without antibiotic treatment. Inappropriate antibiotic use for pharyngitis contributes to the development and spread of antibiotic resistance. However, a small proportion of sore throats caused by group A streptococcal (GAS) infection may benefit from the provision of antibiotics. Establishing the cause of infection is therefore an important step in effective antibiotic stewardship...

BackgroundWidespread ceftriaxone antimicrobial resistance (AMR) threatens Neisseria gonorrhoeae (NG) treatment, with few alternatives available. AMR point-of-care tests (AMR POCT) may enable alternative treatments, including abandoned regimens, sparing ceftriaxone use. We assessed cost-effectiveness of five hypothetical AMR POCT strategies: A-C included a second antibiotic alongside ceftriaxone; and D and E consisted of a single antibiotic alternative, compared with standard care (SC: ceftriaxone and azithromycin)...

BackgroundThe first cases of extensively drug resistant gonorrhoea were recorded in the United Kingdom in 2018. There is a public health need for strategies on how to deploy existing and novel antibiotics to minimise the risk of resistance development. As rapid point-of-care tests (POCTs) to predict susceptibility are coming to clinical use, coupling the introduction of an antibiotic with diagnostics that can slow resistance emergence may offer a novel paradigm for maximising antibiotic benefits. Gepotidacin is a novel antibiotic with known resistance and resistance-predisposing mutations...

Background: Despite increasing recognition of the importance of optimal antibiotic selection and expansion of antimicrobial stewardship activities to ambulatory settings, few studies have examined the frequency of parenteral antibiotic use among ambulatory children. We assessed the prevalence and patterns of parenteral antibiotic administration among ambulatory children in pediatric emergency departments (EDs). Methods: We conducted a cross-sectional assessment of parenteral antibiotic use among ambulatory children aged 0-18 years in 49 US children's hospital EDs in 2018...

OBJECTIVES: This study responds to calls for greater focus on nursing roles, and the need for nursing integration within the antimicrobial optimisation agenda. The objective of this study was to explore Australian hospital nurses' views on antimicrobial resistance and antimicrobial stewardship (AMS) in a hospital setting, in order to better understand the opportunities for and challenges to integration of nursing staff in antimicrobial optimisation within hospital settings. DESIGN: Qualitative one-on-one, semistructured interviews...

BACKGROUND/AIM: Public Health England (PHE) developed an antimicrobial stewardship (AMS) surveillance system and conducted a national pilot to test the feasibility of centrally collecting data from AMS audits performed by NHS Hospital Trusts. The system was simplified, focusing on requirements of the NHS AMR CQUIN (Commissioning for Quality and Innovation; a financial incentive quality improvement scheme). This study presents results and user feedback from the national pilot, and results from using the AMS surveillance system as part of the AMR CQUIN...

Misuse of antibiotics, including unnecessary use or inappropriate selection, may result in side effects and poor outcome in individual patients, as well as contribute to the spread of antimicrobial resistance. Antimicrobial stewardship programs exist to reduce such misuse of antibiotics and ill effect in order to promote patient outcome. The importance of diagnostics, antibiogram data, possible interventions, and impact are reviewed. It is essential for clinical microbiologists and other health care members to understand the field and scope of antimicrobial stewardship, actively participate in, and understand the value they bring to supporting their institution's efforts...
