Assessing antimicrobial stewardship governance in Northeast Brazilian hospitals: a survey-based analysis.

Background: Effective governance of antimicrobial stewardship (AMS) and infection prevention control (IPC) in healthcare facilities is crucial for safeguarding patients against healthcare-associated infections and enhancing patient outcomes by optimizing antibiotic use and curbing the spread of antimicrobial-resistant (AMR) pathogens.

Objectives: To assess the current AMS governance in two public hospitals in Northeast of Brazil, specifically focusing on identifying institutional antibiotic policies and operational practices.

Methods: A survey was conducted by team leaders of both hospitals from 2020 to 2022 using a questionnaire adapted from the Pan American Health Organization (PAHO) recommendations for implementing AMS programmes (ASP) in Latin America and the Caribbean, alongside criteria from the National Health Surveillance Agency (ANVISA) and CDC.

Antimicrobial Stewardship: Leveraging the "Butterfly Effect" of Hand Hygiene.

It is vital that there are coordinated, collaborative efforts to address the threat of antimicrobial resistance (AMR) and to prevent and control the spread of hospital-onset infections, particularly those due to multidrug-resistant (MDR) pathogens. The butterfly effect is a concept in which metaphorically speaking, small, seemingly trivial events ultimately cascade into something of far greater consequence, more specifically by having a non-linear impact on very complex systems. In this regard, antimicrobial stewardship programs (ASP), when implemented alongside infection prevention control (IPC) interventions in hospitals, particularly hand hygiene (HH), are significantly more effective in reducing the development and spread of AMR bacteria than implementation of ASP alone.

Microbiology Assessments in Critically Ill Patients.

The prevalence of suspected or proven infections in critically ill patients is high, with a substantial attributable risk to in-hospital mortality. Coordinated guidance and interventions to improve the appropriate microbiological assessment for diagnostic and therapeutic decisions are therefore pivotal. Conventional microbiology follows the paradigm of "best practice" of specimen selection and collection, governed by laboratory processing and standard operating procedures, and informed by the latest developments and trends.

Clinical management of severe infections caused by carbapenem-resistant gram-negative bacteria: a worldwide cross-sectional survey addressing the use of antibiotic combinations.

Objectives: Optimal treatment of carbapenem-resistant Gram-negative bacteria (CR-GNB) infections is uncertain because of the lack of good-quality evidence and the limited effectiveness of available antibiotics. The aim of this survey was to investigate clinicians' prescribing strategies for treating CR-GNB infections worldwide.

Methods: A 36-item questionnaire was developed addressing the following aspects of antibiotic prescribing: respondent's background, diagnostic and therapeutic availability, preferred antibiotic strategies and rationale for selecting combination therapy.

Best practice: antibiotic decision-making in ICUs.

Purpose Of Review: A major challenge in the ICU is optimization of antibiotic use. This review assesses current understanding of core best practices supporting and promoting astute antibiotic decision-making.

Recent Findings: Limiting exposure to the shortest effective duration is the cornerstone of antibiotic decision-making.

The role of appropriate diagnostic testing in acute respiratory tract infections: An antibiotic stewardship strategy to minimise diagnostic uncertainty in primary care.

Antibiotic resistance has increased worldwide to the extent that it is now regarded as a global public health crisis. Interventions to reduce excessive antibiotic prescribing to patients can reduce resistance and improve microbiological and clinical outcomes. Therefore, although improving outpatient antibiotic use is crucial, few data are provided on the key interventional components and the effectiveness of antibiotic stewardship in the primary care setting, in South Africa.

Emergence of plasmid-mediated colistin resistance (MCR-1) among Escherichia coli isolated from South African patients.

The polymyxin antibiotic colistin is an antibiotic of last resort for the treatment of extensively drug-resistant Gram-negative bacteria, including carbapenemase-producing Enterobacteriaceae. The State of the World's Antibiotics report in 2015 highlighted South Africa (SA)'s increasing incidence of these 'superbugs' (3.2% of Klebsiella pneumoniae reported from SA were carbapenemase producers), and in doing so, underscored SA's increasing reliance on colistin as a last line of defence.

Updated recommendations for the management of upper respiratory tract infections in South Africa.

Background: Inappropriate use of antibiotics for non-severe upper respiratory tract infections (URTIs), most of which are viral, significantly adds to the burden of antibiotic resistance. Since the introduction of pneumococcal conjugate vaccines in 2009 in South Africa, the relative frequency of the major bacterial pathogens causing acute otitis media (AOM) and acute bacterial rhinosinusitis (ABRS) has changed.

Recommendations: Since URTIs are mostly viral in aetiology and bacterial AOM and ABRS frequently resolve spontaneously, the guideline includes diagnostic criteria to separate viral from bacterial causes and hence, those patients not requiring antibiotics.
