The Coronavirus disease 2019 (COVID-19) pandemic increased the burden of critically ill patients who required hospitalization in the intensive care unit (ICU). Bacterial and fungal co-infections, including bloodstream infections (BSIs), increased significantly in ICU patients with COVID-19; this had a significant negative impact on patient outcomes. Reported data pertaining to BSI episodes from the ICU setting during the COVID-19 pandemic were collected and analyzed for this narrative review. We searched the PubMed database for articles published between March 2020 and October 2023; the terms “COVID-19” AND “bloodstream infections” AND “ICU” were used for the search. A total of 778 articles were retrieved; however, only 27 were exclusively related to BSIs in ICU patients with COVID-19. Data pertaining to the epidemiological characteristics, risk factors, characteristics of bacterial and fungal BSIs, patterns of antimicrobial resistance, and comparisons between ICU and non-ICU patients during and before the COVID-19 pandemic were obtained. Data on antimicrobial stewardship and infection-control policies were also included. The rates of BSI were found to have increased among ICU patients with COVID-19 than in non-COVID-19 patients and those admitted during the pre-pandemic period. Male gender, 60–70 years of age, increased body mass index, high Sequential Organ Failure Assessment scores at admission, prolonged hospital and ICU stay, use of central lines, invasive ventilation, and receipt of extracorporeal membrane oxygenation were all defined as risk factors for BSI. The use of immune modulators for COVID-19 appeared to increase the risk of BSI; however, the available data are conflicting. Overall, Enterococci, Acinetobacter baumannii, and Candida spp. emerged as prominent infecting organisms during the pandemic; along with Enterobacterales and Pseudomonas aeruginosa they had a significant impact on mortality. Multidrug-resistant organisms prevailed in the ICU, especially if antimicrobial resistance was established before the COVID-19 pandemic and were significantly associated with increased mortality rates. The unnecessary and widespread use of antibiotics further increased the prevalence of multidrug-resistant organisms during COVID-19. Notably, the data indicated a significant increase in contaminants in blood cultures; this highlighted the decline in compliance with infection-control measures, especially during the initial waves of the pandemic. The implementation of infection-control policies along with antibiotic stewardship succeeded in significantly reducing the rates of blood contamination and BSI pathogens. BSIs considerably worsened outcomes in patients with COVID-19 who were admitted to ICUs. Further studies are needed to evaluate adequate preventive and control measures that may increase preparedness for the future.

Summary: Background: The United States Food and Drug Administration recently announced a national blood culture (BC) bottle shortage; the exact date of restoration is still being determined. Aim: Implement a workflow to mitigate the BC bottle shortage at our hospital. Methods: We created the following clinical decision support workflow in electronic medical record to help mitigate BC bottle use: (a) limit to two BC in 24 hours, (b) only repeat BC if 72 hours have passed from the prior sets, (c) do not repeat BC for coagulase-negative Staphylococcus bacteremia when considered a contaminant (i.e., no implanted vascular device), (d) do not repeat BC for Streptococcus bacteremia, (e) do not repeat cultures for Gram-negative rod bacteremia unless an unknown source, immunosuppression, or clinical worsening. Findings: Post implementation, our weekly average BC bottle use decreased to 29.5%. Conclusion: Within three weeks of the BC bottle shortage announcement, we successfully deployed evidence-based BC restrictions in the electronic medical record (EMR), reducing our BC orders by 29.5%. We encourage others to consider and potentially replicate our workflow to contribute to diagnostic stewardship.

Background: The mass gathering in Hajj (Islamic pilgrimage) makes the spread of infectious diseases inevitable. Antibiotics are frequently prescribed during this season. We aimed to measure antimicrobial utilization during the 2022 Hajj and evaluate the practice using quality indicators. Methods: Antimicrobial utilization by Hajj medical facilities (77 primary clinics and 7 hospitals) was measured using the anatomic therapeutic classification defined daily dose (DDD) and DDD/1,000-inhabitant/day (DID), where inhabitants were the Hajj 2022 pilgrims (n = 899,353). Quality indicators included percentages of consumption of different antibiotic classes of the total consumption of antibacterials for systemic use in DID. Results: During Hajj, there was 87,173 outpatient visits and 740 hospitalizations (215 critically ill). Amoxicillin was the most prescribed antibiotic (DID=11.708) followed by azithromycin (DID=7.395). Penicillins fell in the second quartile (i.e., highly prescribed) with a quality indicator value (J01_CE%) of 48.149. The consumption of other antibacterials, including fluoroquinolones, fell in the first quartile (

Introduction: Chronic Obstructive Pulmonary Disorder (COPD) was estimated to be the sixth leading cause of death in 2019, and second most common cause of non-communicable disease-related deaths in India. Systemic or inhaled corticosteroid use must be assessed against any known toxicities risk to determine potential benefits. Thus, there should be a system to streamline the utilization of corticosteroids in COPD patients. Objective: To highlight the potential of clinical markers in promoting steroid stewardship. Additionally this study also emphasizes the need to identify more clinical markers that could determine steroid efficacy and help in tailoring the therapy for patients with COPD. Methodology: Two independent researchers conducted a systematic review to recognize the markers affecting COPD therapy. A literature search was conducted using a thorough search strategy, including search terms “COPD,” “corticosteroids,” “biomarkers,” and related MeSH terms to recruit all relevant literature between 2007 and 2023. In total, 919 PubMed, Embase, and Scopus articles were screened, and 16 were finalized. Results: After thoroughly screening articles, two biomarkers were identified from the review. The majority (n = 13) stated that blood eosinophil count (BEC) could impact steroid therapy in COPD patients, further strengthened by the latest Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines. Fractional Exhaled Nitric Oxide (FeNO) is another component captured from (n = 3) studies presenting its benefit in directing corticosteroid therapy in COPD patients. Conclusion: This study showed that with an understanding of patient history, using BEC and FENO to determine steroid therapy in COPD could benefit. Although more studies are required, it is believed these markers can individualize steroid therapy, leading to better patient care and shaping the core of the steroid stewardship program.

Livestock associated antimicrobial resistance (AMR) can reduce productivity and cause economic losses, threatening the livelihoods of poor farming communities in low-income settings. We investigated the practices and risk factors for increased antibiotic use, and AMR in Escherichia coli including resistance to human critically important antibiotics like cefotaxime and colistin in semi-intensive and free-range poultry farms in Uganda. Samples and farm management data were collected from 402 poultry farms in two districts between October 2021 to March 2022. Samples were processed to isolate E. coli and to quantify cefotaxime (CTX) and colistin (COL) resistant coliforms. The identification of presumptive E. coli isolated on MacConkey agar without antibiotics, was confirmed by matrix-assisted laser desorption/ionization-time of flight mass spectrometry and subjected to antimicrobial susceptibility testing by disk diffusion using EUCAST guidelines. Our models indicated that antibiotic use was associated with production intensity, and type of feed used. Moreover, semi-intensive farmers had better knowledge on antibiotic use compared to farmers in the free-range system. In semi-intensive farms, 52% harbored COLR and 57% CTXR coliforms. In free-range farms, 54% had COLR and 67% CTXR coliforms. Resistance to tetracycline, ampicillin and enrofloxacin were more frequent in semi-intensive farms compared to the free-range farms. Multi-drug resistant E. coli were identified in both poultry production systems despite different management and antibiotic use practices. There was no significant relationship between antibiotic use and resistance for the six antibiotics tested.

Summary: Introduction: Historically, antimicrobial stewardship (AMS) has considered the judicious use of antibiotics. AMS is widely adopted across Europe and the US; recently antifungal AMS is gaining momentum but antiviral AMS has been little described. Here we describe the introduction of AMS virology reviews at University Hospitals Birmingham (UHBFT); a novel concept and an opportunity to broaden the beneficial aspects of AMS to virology, termed anti-viral stewardship (AVS). Method: In June 2022, a UK supply issue with aciclovir injection (ACV IV) was announced. In order to review and preserve parenteral ACV for those in greatest need, UHBFT pharmacist and virologists implemented a specialist review for patients prescribed more than 48 hours of treatment. This review initially lasted 10 weeks and data was collected on the advice offered, whether it was accepted, and time required completing the review. Results: AVS rounds halved IV ACV consumption, compared to pre or post intervention levels, with more than half of patients advised to stop or switch to oral therapy. Diagnostics and sampling guidance was offered in one quarter of reviews, whilst the remaining interventions were more stewardship focused. In almost all cases stewardship advice was readily accepted by clinical teams. Due to positive feedback from clinicians and its effective management of supply, the anti-viral stewardship (AVS) programme was re-introduced in June 2023. Conclusions: Antiviral AMS rounds provide an opportunity to optimise sampling, diagnosis and improve patient management. Introduction of regular AVS at UHBFT are now well established and plan to be implemented in other hospitals.

Background: Overuse or misuse of antimicrobials is common in pediatric intensive care units (PICU) and may be associated with poor clinical outcomes. Although an antimicrobial stewardship program (ASP) has been found to improve this practice, the required expertise in infectious diseases may be limited in some centers. We aimed to evaluate the effect of telehealth ASP on the rate of PICU antimicrobial use in a center without a local Infectious Diseases consultation service. Methods: A retrospective cohort study was performed between October 1st, 2018, and October 31st, 2020, in Farwaniya Hospital PICU, a 20-bed unit. All pediatric patients who were admitted to PICU and received systemic antimicrobials during the study period were included and followed until hospital discharge. The ASP team provided weekly prospective audit and feedback on antimicrobial use starting October 8th, 2019. A pediatric infectious diseases specialist joined the ASP rounds remotely. Descriptive analyses and a pre-post intervention comparison of days of therapy (DOT) were used to assess the effectiveness of the ASP intervention. Results: There were 272 and 156 PICU admissions received systemic antimicrobial before and after the initiation of ASP, respectively. Bronchiolitis and pneumonia were the most common admission diagnoses, together compromising 60.7% and 61.2% of cases pre- and post-ASP. The requirement for respiratory support was higher post-ASP (76.5% vs. 91.5%, p

Background: The ageing population poses significant challenges to healthcare systems, necessitating the establishment of high-functioning, integrated frameworks for elderly healthcare. This study aimed to explore the key challenges associated with the stewardship of elderly care in Iran and to develop a holistic stewardship framework. Methods: For this qualitative study, thirty semi-structured interviews were conducted with key Iranian healthcare stakeholders, utilizing purposive and snowball sampling during 2021–2022. Inductive open coding was utilized to generate new concepts related to key stewardship challenges. The World Health Organization's conceptual framework, outlining the three stewardship tasks, served as the basis for crafting a tailored framework for elderly healthcare stewardship in Iran. Results: Fourteen main challenges and 38 sub-challenges were identified for elderly healthcare stewardship in Iran, categorized according to the WHO framework's three stewardship tasks. Challenges related to WHO stewardship task 1, involving health policy formulation and vision definition, included challenges in vision definition, planning, policymaking, and intergovernmental institutional superiority. Challenges related to WHO stewardship task 2, delineating governance and stewardship through control and regulation, encompassed issues such as support for the elderly, system responsiveness, behavior of healthcare providers, organizational structure, and cross-sectoral leadership challenges. Challenges associated with WHO stewardship task 3, about the use of collective intelligence, explored stakeholder collaboration, information for decision-making, and challenges within the elderly information system, covering data documentation, reporting, analysis, accessibility, distribution, and circulation. Subsequently, a framework was developed, covering areas like defining the vision and direction of health policy, managing information systems, evidence-informed policymaking, and delivering elderly health services with a holistic approach. Conclusion: The present framework shows how a management information system, guided by evidenced-informed policymaking and the formulation of customized health policies, can facilitate the provision of elderly health services based on identified needs. It presents a governance and stewardship pathway that can be adopted by Iranian health policymakers and similar middle-income countries facing analogous challenges in ageing and aged care system stewardship, serving as a model for developing their own frameworks.

Background: The use of anticoagulant medications is complex and prone to inappropriate prescribing that impacts patient safety. Anticoagulation stewardship is a growing field that requires more focus and attention. Aim: This review aimed to retrieve and synthesise the available research studies on the clinical and economic value of Anticoagulation Stewardship Programmes (ASPs) in line with the Anticoagulation Forum Core Elements of Anticoagulation Stewardship. Methods: A comprehensive electronic literature search was conducted using three databases (Cochrane Central Register of Controlled Trials (CENTRAL), Embase and PubMed) from inception up to and including January 2023. Inclusion criteria were primary research studies where the purpose of the study was any hospital ASP intervention applicable to optimising antithrombotic drug use, across all anticoagulation medications and in adult hospital inpatients. Results: A total of 787 records were identified after duplicates were removed. Twenty-eight papers were included in this review. Twenty-four of these studies were single-centre studies; four of these studies were multi-centre studies. Eleven studies took a prospective approach, fifteen took a retrospective approach and two were quasi-experimental studies. Interventions implemented by either multidisciplinary ASP teams or pharmacist-led anticoagulation services included the provision of education to healthcare professionals and patients, undertaking medication reviews and implementing guidelines and protocols, and interventions to facilitate transitions of care. Clinical benefits to patients and cost savings were observed across many studies. Conclusion: Implementing multidisciplinary ASP teams and pharmacist-led anticoagulation services is associated with an overall improvement in the safe use of anticoagulation among hospital patients. Studies identified incorporated some of the core elements of ASP, however further work and research are necessary to standardise the adoption and implementation of ASP and ensure that it is prioritised among healthcare professionals, in the healthcare setting, and among health systems and policy-makers.

ABSTRACT: Introduction: Antibiotic resistance is a global health crisis. Ensuring responsible, appropriate use (stewardship) is an important for keeping antibiotics working as long as possible. Around 10% of antibiotics across health care are prescribed by oral health care professionals, with high rates of unnecessary use. To maximise the value from research to optimise antibiotic use in dentistry, this study developed international consensus on a core outcome set for dental antibiotic stewardship. Methods: Candidate outcomes were sourced from a literature review. International participants were recruited via professional bodies, patient organisations, and social media, with at least 30 dentists, academics, and patient contributors in total. Outcomes scored “critical for inclusion” by >70% of the participants (dentists, academics, and patients) after 2 Delphi rounds were included in the core outcome set following a final consensus meeting. The study protocol was registered with the COMET Initiative and published in BMC Trials. Results: A total of 33 participants from 15 countries, including 8 low- and middle-income countries, completed both rounds of the Delphi study. Antibiotic use outcomes (eg, appropriateness of prescribing), adverse or poor outcomes (eg, complications from disease progression), and a patient-reported outcome were included in the final, agreed core set. Outcomes relating to quality, time, and cost were not included. Conclusions: This core outcome set for dental antibiotic stewardship represents the minimum which future studies of antibiotic stewardship in dentistry should report. By supporting researchers to design and report their studies in a way meaningful to multiple stakeholders and enabling international comparisons, the oral health profession's contribution to global efforts to tackle antibiotic resistance can be further improved.

We explored the self-reported antibiotic stewardship (AS), and infection prevention and control (IPC) activities in intensive care units (ICUs) of different income settings. A cross-sectional study was conducted using an online questionnaire to collect data about IPC and AS measures in participating ICUs. The study participants were Infectious Diseases–International Research Initiative (IDI-IR) members, committed as per their institutional agreement form. We analyzed responses from 57 ICUs in 24 countries (Lower-middle income (LMI), n = 13; Upper-middle income (UMI), n = 33; High-income (HI), n = 11). This represented (~5%) of centers represented in the ID-IRI. Surveillance programs were implemented in (76.9%−90.9%) of ICUs with fewer contact precaution measures in LMI ones (p = 0.02); (LMI:69.2%, UMI:97%, HI:100%). Participation in regional antimicrobial resistance programs was more significantly applied in HI (p = 0.02) (LMI:38.4%,UMI:81.8%,HI:72.2%). AS programs are implemented in 77.2% of institutions with AS champions in 66.7%. Infectious diseases physicians and microbiologists are members of many AS teams (59%&50%) respectively. Unqualified healthcare professionals(42.1%), and deficient incentives(28.1%) are the main barriers to implementing AS. We underscore the existing differences in IPC and AS programs’ implementation, team composition, and faced barriers. Continuous collaboration and sharing best practices on APM is needed. The role of regional and international organizations should be encouraged. Global support for capacity building of healthcare practitioners is warranted.

Background: It is unclear what is responsible for the large variations in the prevalence of meningococcal resistance to cephalosporins and quinolones. Methods: We used mixed-effects linear regression to assess if country-level prevalence of reduced susceptibility to cefotaxime and ciprofloxacin was associated with the population-level consumption of cephalosporins and quinolones in 13 European countries. Results: Positive correlations were found between the prevalence of reduced susceptibility to ciprofloxacin and the consumption of quinolones (coef. 0.16, 95% CI 0.05–0.27; P = 0.003). The same positive association was found for cefotaxime/cephalosporins (coef. 0.1, 95% CI 0.04–0.15; P = 0.001). Conclusions: Meningococcal reduced susceptibility to cefotaxime and ciprofloxacin is linked to homologous class antimicrobial consumption. This finding provides additional motivation for strengthening antimicrobial stewardship programs.

ABSTRACT: Objectives: Little is known about the benefits of timely switch from intravenous (IV) to oral antibiotic therapy in children. We evaluated the appropriateness of IV-to-oral switch of antibiotic therapy in remote and regional areas of Australia following the implementation of a multifaceted package of interventions. Methods: The intervention package, including clinician guidelines, medication review stickers, patient information leaflets and educational resources, was implemented in seven facilities in Queensland, Australia. Children with community-acquired pneumonia and skin and soft-tissue infections were switched to oral therapy if they met the required ‘IV-to-oral switch’ criteria. Data were collected for a 7-month period from May to November for the baseline (2018) and intervention (2019) phases. Results: A total of 357 patients were enrolled in the study, including 178 in the baseline phase and 179 in the intervention phase. The percentage of patients who switched to oral therapy or stopped IV antibiotics, within 24 h of eligibility, increased from 87.6% (156/178) in the baseline phase to 97.2% (174/179) in the intervention phase (P = 0.003). The average number of extra IV days decreased from 0.45 days in the baseline period to 0.18 days in the intervention period (P < 0.001). The median patient length of stay was 2 days for both phases. The only adverse events recorded were line-associated infiltration, with a decrease from 34.3% (61/178) (baseline) to 17.9% (32/179) (intervention) (P < 0.001). Conclusion: A multifaceted intervention package to enhance timely IV-to-oral switch of antibiotic therapy for children in remote and regional facilities is effective.

Introduction: Antimicrobial stewardship aims to slow the emergence of antimicrobial resistance. We conducted a systematic review on the use of digital antimicrobial stewardship programmes (ASP) on antimicrobial usage, cost, length of stay (LoS) and mortality. Methods: We identified, quality appraised using the Newcastle-Ottawa scale, and descriptively and narratively synthesised data on primary research articles that implemented an ASP(s) for adult inpatients for at least six months, and reported antimicrobial usage as defined daily dose (DDD) per 1000 patient days and at least one of: LoS, mortality or cost. Our review was registered with PROSPERO: CRD42020154124 and adhered to the PRISMA guideline. Results: Our searches retrieved 3,997 titles, from which 13 studies were included. The risk of bias assessment resulted in 10 studies receiving a rating of 7 stars or over. A range of ASPs were implemented using computerised decision support (CDS) systems, including those that combined audit and feedback, guidelines and approval, computerised approval processing, computerised recommendations and surveillance. All studies found a decrease in antimicrobial usage (DDD range, −8.42% to −61.29%). All six studies that considered costs also showed a decrease (range, −8.12% to −69.19%). Six studies reported a decrease in mortality and one showed no change. Discussion: The digital ASP programmes investigated appeared to have a positive impact on antimicrobial usage and clinical outcomes. Our review found that ASPs that utilised an audit and feedback approach showed a promising and consistent reduction in DDD.

Background: Community-acquired pneumonia (CAP) is a leading cause of morbidity and mortality worldwide. Limited evidence is available on the most effective diagnostic approaches, management strategies, and long-term outcomes for CAP in patients who have undergone solid organ transplantation., Research Question: What is the acute and long-term morbidity and mortality after CAP in organ transplant recipients?, Study Design and Methods: We retrospectively analyzed hospitalizations for CAP in solid organ recipients at the largest German transplant center. The study included patients admitted between January 1, 2010, and May 31, 2021. The reported outcomes are in-hospital and 1-year mortality, risk of cardiovascular events during hospitalization and at 1 year, admission to the ICU, and risk of pneumonia with Pseudomonas aeruginosa. Multivariable binary logistic regression using stepwise forward selection was performed to determine predictive factors for pneumonia with P aeruginosa., Results: We analyzed data from 403 hospitalizations of 333 solid organ recipients. In > 60% of cases, patients had multiple comorbidities, with cardiovascular and chronic kidney disease being the most prevalent. More than one-half of the patients required oxygen supplementation after admission. In-hospital mortality (13.2%) and the death rate at 1 year postevent (24.6%) were higher than data reported from immunocompetent patients. We also observed high rates of acute cardiovascular events and events occurring 1 year after admission. Early blood cultures and bronchoscopy in the first 24 h significantly increased the odds of establishing an etiology. In our low-resistance setting, the burden of antimicrobial resistance was driven by bacteria from chronically colonized patients, mostly lung transplant recipients., Interpretation: This comprehensive analysis highlights the high morbidity associated with CAP after transplantation. It also emphasizes the need for prospective multicenter studies to guide evidence-based practices and improve outcomes for these vulnerable patients., Competing Interests: Financial/Nonfinancial Disclosures None declared., (Copyright © 2024 The Author(s).

Urban tree planting is a key climate change resilience strategy for many municipalities, but remains challenged by establishment mortality in semi-arid regions. Street trees offer shade benefits to adjacent structures and pavement, and enable public works departments to implement heat island reduction interventions to exposed communities. But in Los Angeles, resident approval and written agreement to water for 3–5 years is required to plant street trees in residential public rights of way. Historically, 10% of residents contacted agreed to adopt street trees, and 50% of trees planted survived. Community engagement strategies, shown to improve tree acceptance rates and survival elsewhere, had not been tested here. This mixed-methods evaluation of a street tree planting and public education project in 2018 evaluated a novel youth outreach strategy to engage residents. Regular watering was provided post-transplant for varying periods. Residents were surveyed and project partners were interviewed; tree health was assessed visually. Resident feedback on the engagement strategy was strongly positive. Residents surveyed demonstrated measured learning outcomes, and satisfaction with education was associated with improved tree survival. Project partners identified numerous co-benefits, primarily among youth educators, and revealed an increased capacity for future urban greening work. Univariate logistic regression identified tree species, weeks of watering, and drought exposure as predictors of tree health (p < .05), but in a multivariate model, only certain tree species were significant (p < .05). This evaluation identifies multiple strategies to inform future tree planting projects, increase street tree acceptance and establishment survival, and support community co-benefits.

ABSTRACT: Objectives: This study aimed to identify the status of antimicrobial stewardship programmes (ASPs) in small to medium-sized Korean hospitals as well as the awareness and demands about ASPs of physicians. Methods: A questionnaire was designed based on a questionnaire from a previous nationwide survey in 2018 targeting large hospitals in Korea and modified to reflect the results of in-depth interviews with non-infectious diseases (IDs) physicians at secondary care hospitals. The survey targeted all hospitals with ≥150 beds in South Korea and was performed in May–June 2020. Only one ASP-associated physician per hospital participated in the survey. Results: The survey response rate was 31.9% (217/680). ID specialists comprised the majority of medical personnel participating in ASPs in tertiary care hospitals. Conversely, in secondary and primary care hospitals there was no predominant medical personnel for ASPs and the median full-time equivalent was 0 for all types of medical personnel. Tertiary care hospitals, more than secondary and primary care hospitals, tended to perform ASP activities more actively. ‘Workforce for ASPs’, ‘Establishment of healthcare fees for ASPs’ and ‘Development of tools for ASPs’ were the most important required support for ASP improvement. Conclusion: The level of ASP establishment was more limited in primary care hospitals than in secondary and tertiary care hospitals in Korea. To improve ASPs in Korean hospitals, a supporting workforce and the establishment of a healthcare fee for ASPs appear to be necessary.

Purpose: To outline hospital pharmacy practices across the Gulf Cooperation Councils (GCC) countries’ hospitals. Methods: A modified survey questionnaire was prepared from the original 2019 American Society of Health-System Pharmacist (ASHP) survey questions. Survey details were discussed with some pharmacy directors for clarity and relevance. A list of hospitals were obtained from the Ministry of Health of each of the targeted GCC countries. A secure invitation link containing a survey questionnaire was sent to the participants directly. Results: Sixty four hospitals responded to this survey. The overall response rate was 52%. About 47% of the surveyed hospitals considered their drug formularies as closed, and strict. Additionally, only 44% of hospitals compare the effectiveness of products, when taking formulary decisions for drug inclusion. Forty-four percent of hospitals have computerized prescriber order entry (CPOE / EHR) system functionality for formulary system management. At about 39.1% hospitals, pharmacists have the responsibility for managing medication therapies, majority were engaged in providing anticoagulation therapies. About 61% of hospital pharmacies in GCC countries receive medication orders electronically, through CPOE/EHR. Majority (66%) of the hospitals in GCC countries have an active Antimicrobial Stewardship Program (ASP) while only 40% of pharmacists have a key role in providing clinical support. About 57.8% of hospital pharmacy directors reported that pharmacists do not provide ambulatory care clinical pharmacy services in their hospitals. Conclusion: In GCC countries’ hospitals, there are major areas for improvement to patient care of which pharmacists are uniquely qualified as the medication experts to have the most meaningful outcomes in all of the domains of safe medication use, medication therapy management, antimicrobial stewardship program and participation in outpatient clinics.

Antimicrobial resistance (AMR) continues to exert a substantial toll on the global health and world economy and is now expected to be hidden by COVID-19 for a while. The wrong consumption of antibiotics during the COVID-19 pandemic will raise disastrous effects on AMR management and antibiotic stewardship programs. This is related to the concerns extrapolated due to an increase in mortality rates in patients with bacterial coinfections. Importantly, the immune system of COVID-19 patients in regions with high AMR may be fighting on two fronts altogether, the virus and MDR bacteria. Current control policies to manage AMR and prioritization of antibiotic stewardship plans are mandatory during this pandemic. This review aims to discuss the rising concerns of the excess use of antibiotics in COVID-19 patients highlighting the role of bacterial coinfections in these patients. Types of prescribed antibiotics and the development of antibiotic resistance is addressed as well.

Objectives: Observational and experimental studies suggest that the use of antibiotics close to administration of immune checkpoint inhibitors (ICI) can have a negative effect on tumour response and patient survival, due to microbiome dysbiosis and the resultant suppression of host immune response against neoplastic cells. Methods: A systematic search of PUBMED and EMBASE was undertaken for studies published between 1 January 2017 and 1 June 2020, evaluating the association between the use of antibiotics and clinical outcomes in patients with cancer treated with ICIs. A meta-analysis of the association between the use of antibiotics and clinical outcomes was also performed. Results: Forty-eight studies met the inclusion criteria (12,794 patients). Use of antibiotics was associated with shorter overall survival [hazard ratio (HR) 1.88, 95% confidence interval (CI) 1.59–2.22; adjusted HR 1.87, 95% CI 1.55–2.25] and progression-free survival (HR 1.52, 95% CI 1.36–1.70; adjusted HR 1.93, 95% CI 1.59–2.36), decreased response rate [odds ratio (OR) 0.54, 95% CI 0.34–0.86] and more disease progression (OR 2.00, 95% CI 1.27–3.14). The negative association between the use of antibiotics and progression-free survival was stronger in patients with renal cell carcinoma or melanoma compared with lung cancer. Only antibiotic administration >1 month prior to ICI initiation was associated with increased disease progression. Heterogeneity was substantial for all outcomes. Conclusions: Recent use of antibiotics in patients with cancer treated with ICIs was associated with worse clinical outcomes. Such patients may benefit from dedicated antimicrobial stewardship programmes.

Antimicrobials including antibiotics, antiparasitic, and antifungals, are subjected to resistance. In this context, Public Health Organizations called for a One Health approach because antimicrobials used to treat different infectious diseases in animals and plants may be the same than those used in humans. Whereas mechanisms of resistance transmission from animals or environment to humans should be considered differently if related to prokaryotic or eukaryotic pathogens, their impact can be considered as a whole. In that respect, we discussed the use of anti-parasitic in animals including anticoccidials, anthelmintics, and insecticides-acaricides, and the use of azoles in the environment that may both favor the development of drug resistance in humans. In light of the current situation, there is an urgent need for a transdisciplinary approach through anti-parasitic and antifungal stewardship programs in humans, animals, and environment, especially in the era of COVID-19 pandemic that will probably aggravate antimicrobial resistance.

Objectives: Recurrent urinary tract infections (rUTIs) occur frequently after kidney transplantation (KT), however their optimal management remains undefined. This study aimed to identify risk factors for rUTI and to validate a protocol for UTI and rUTI treatment after KT. Methods: This retrospective cohort study involved patients undergoing KT between January 2013 and July 2016. Patients were followed-up from day of KT until graft loss, death or end of follow-up (31 December 2018). We analysed all episodes of symptomatic UTI. The main outcome measure was rUTI after KT. Analysis was done per episode in a multilevel approach; patient features were considered in the distal level and UTI features in the proximal level. Univariate and multivariate analyses were performed by Cox regression. A propensity score was used to adjust the risk of patients with carbapenem-resistant Enterobacteriaceae. Results: During the study period, 787 patients underwent KT, of whom 152 (19.3%) developed 356 UTI episodes. The most common micro-organisms wereEscherichia coli (165/356; 46.3%) and Klebsiella pneumoniae (101/356; 28.4%). Multidrug-resistant micro-organisms were isolated in 161 UTIs (45.2%). Risk factors for rUTI were diabetic nephropathy as the cause of end-stage renal disease (P = 0.02), UTI in first 180 days after KT (P = 0.04), anatomic alteration of the urinary tract at UTI diagnosis (P = 0.004) and length of time to effective therapy (P = 0.002); UTI treatment duration according to institutional protocol (P = 0.04) was the only protective factor identified. Conclusion: Appropriate therapy duration has an impact on rUTI prevention after KT.

Objectives: The prevalence of Neisseria gonorrhoeae NG-MAST genogroup G1407, associated with decreased susceptibility to extended-spectrum cephalosporins and fluoroquinolone resistance, has declined in Europe and it switched from circulating predominantly in men who have sex with men (MSM) in 2009–2010 to heterosexuals in 2013. We hypothesise that changes to gonorrhoea treatment guidelines combined with differences in country-level consumption of cephalosporins and quinolones contributed to this shift. Methods: Linear regression was used to evaluate the association between changes in prevalence of G1407 between 2009–2010 and 2013 and country-level consumption of quinolones and cephalosporins in 2011/12 in 20 European countries. Results: Whilst the prevalence of G1407 declined between 2009–2010 and 2013 in the EU/EEA, its absolute prevalence increased by 10% or more in three countries. The national prevalence of G1407 in 2013 was positively associated with population-level general cephalosporin and quinolone consumption in the preceding 2 years. The association between the prevalence of G1407 and proportion of the national sample derived from MSM was non-significant in 2009–2010 and was negative in 2013. Conclusions: Our results are broadly compatible with the hypothesis that changes in gonorrhoea therapy to the more efficacious ceftriaxone (plus azithromycin) from 2010 to 2011 onwards resulted in a reduced prevalence of the resistance-associated G1407 overall but in MSM in particular. High population-level consumption of quinolones and cephalosporins in certain countries then contributed to the selection of G1407 predominantly in heterosexuals in these countries.

Background: The reasons underpinning the large variations in the prevalence of childhood obesity are inadequately understood. Individual level studies have found that macrolide consumption at a young age increases the risk of subsequent obesity. We hypothesized that differences in population level consumption of macrolides may explain part of the variation in the prevalence of childhood obesity. Methods: Mixed effects beta regression was used to assess the association between the prevalence of childhood obesity in countries in Europe/ states in the United States and population level consumption of macrolides and total antibiotics. Different time lags between consumption and obesity measurement were used. Results: We found that in both the USA and Europe, population level consumption of macrolides was positively associated with subsequent childhood obesity prevalence. According to our model, the observed differences in population-level macrolide consumption in Europe/USA would translate into a 13%/72% higher odds of childhood obesity 5 years later. The association held regardless of the lag period used between exposure and outcome. The association with total antibiotic consumption was more equivocal. Conclusions: Reducing macrolide consumption to that of low consumption countries may result in considerable reductions in childhood obesity.

Introduction: Stewardship programs have been developed to optimize the use of antibiotics, but programs focusing on antifungal agents are less frequent. Objective: To evaluate the quality of antifungal prescriptions in a tertiary care hospital, and to test if a simple educational activity could improve the quality of prescriptions. Methods: The study comprised three phases: 1) Retrospective audit of all antifungal prescriptions in a 6-month period, applying a score based on six parameters: indication, drug, dosage, route of administration, microbiologic adequacy after results of cultures, switching to an oral agent, and duration of treatment; 2) Creation of text boxes in the electronic medical records with information about antifungal agents, shown during prescription; 3) Retrospective audit of all antifungal prescriptions in a 6-month period, applying the same 6-parameters score, and comparison between the two periods. Results: Among 333 prescriptions, fluconazole was the most frequently (80.5%) prescribed agent. Hematology (26.7%), Infectious Diseases Department (22.8%), Internal Medicine (15.9%) and Intensive Care Unit (14.4%) were the units with most antifungal prescriptions. The median score for the 333 prescriptions was 8.0 (range 0 – 10), and 72.7% of prescriptions were considered inappropriate. The median and mean scores in the first and second audit were 8.0 and 6.9, and 8.0 and 7.9, respectively (p

Antimicrobial resistance must be recognised as a global societal priority - even in the face of the worldwide challenge of the COVID-19 pandemic. COVID-19 has illustrated the vulnerability of our healthcare systems in co-managing multiple infectious disease threats as resources for monitoring and detecting, and conducting research on antimicrobial resistance have been compromised during the pandemic. The increased awareness of the importance of infectious diseases, clinical microbiology and infection control and lessons learnt during the COVID-19 pandemic should be exploited to ensure that emergence of future infectious disease threats, including those related to AMR, are minimised. Harnessing the public understanding of the relevance of infectious diseases towards the long-term pandemic of AMR could have major implications for promoting good practices about the control of AMR transmission.

We present a new concept, Punt Politics, and apply it to the COVID-19 non-pharmaceutical interventions (NPI) in two epicenters of the pandemic: Mexico and Brazil. Punt Politics refers to national leaders in federal systems deferring or deflecting responsibility for health systems decision-making to sub-national entities without evidence or coordination. The fragmentation of authority and overlapping functions in federal, decentralized political systems make them more susceptible to coordination problems than centralized, unitary systems. We apply the concept to pandemics, which require national health system stewardship, using sub-national NPI data that we developed and curated through the Observatory for the Containment of COVID-19 in the Americas to illustrate Punt Politics in Mexico and Brazil. Both countries suffer from protracted, high levels of COVID-19 mortality and inadequate pandemic responses, including little testing and disregard for scientific evidence. We illustrate how populist leadership drove Punt Politics and how partisan politics contributed to disabling an evidence-based response in Mexico and Brazil. These cases illustrate the combination of decentralization and populist leadership that is most conducive to punting responsibility. We discuss how Punt Politics reduces health system functionality, providing lessons for other countries and future pandemic responses, including vaccine rollout.

Background: Earlier studies have reported high antibiotic use in patients hospitalised for coronavirus disease 2019 (COVID-19), resulting in concerns of increasing antimicrobial resistance with increase antibiotic use in this pandemic. Point prevalence survey (PPS) can be a quick tool to provide antibiotic prescribing information to aid antimicrobial stewardship (AMS) activities. Objectives: To describe antibiotic utilization and evaluate antibiotic appropriateness in COVID-19 patients using PPS. Methods: Adapting Global-PPS on antimicrobial use, the survey was conducted in COVID-19 wards at 2 centres in Singapore on 22 April 2020 at 0800h. Patients on systemic antibiotics were included and evaluated for antibiotic appropriateness. Results: Five hundred and seventy-seven patients were screened. Thirty-six (6.2%) patients were on antibiotics and which were started at median of 7 days (inter-quartile rate (IQR), 4, 11) from symptom onset. Fifty-one antibiotics were prescribed in these patients. Overall, co-amoxiclav (26/51, 51.0%) was the most often prescribed antibiotic. Thirty-one out of 51 (60.8%) antibiotic prescriptions were appropriate. Among 20 inappropriate prescriptions, 18 (90.0%) were initiated in patients with low likelihood of bacterial infections. Antibiotic prescriptions were more appropriate when reviewed by infectious diseases physicians (13/31 [41.9%] versus 2/20 [10.0%], p = 0.015), and if reasons for use were stated in notes (31/31 [100.0%] versus 16/20 [80.0%], p = 0.019). Conclusions: Despite low prevalence of antibiotic use among confirmed and suspected COVID-19 patients at 2 centres in Singapore, there was significant proportion of inappropriate antibiotics use where bacterial infections were unlikely. AMS teams can tailor stewardship strategies using PPS results.

Nanotechnology has increasing applications in numerous markets, particularly in additive processing (3D printing) and manufacturing, which is important for consumer products, medical devices, construction, and general research and development across many other industries. Nanomaterials are desirable in many products due to their unique properties, but those same properties have made evaluating the risk and regulation of these materials challenging. For risk-based regulations, new applications and nanomaterials should be assessed for both human and environmental hazards and exposure to ensure protection. In general, many risk assessments to date have focused on the non-nano versions of chemicals. The lack of guidance on assessing the hazard and exposure of nanomaterials in 3D printing is apparent, and these areas of assessment are actively being evaluated. Industry in most cases will now need to provide specific additional information for assessing the risk of nanomaterials in 3D printing. This review paper focuses on the use of nanomaterials in 3D printing for industrial and manufacturing applications, summarizes the current literature on human health and safety related to 3D printing and inhalation exposure, and the regulations relating to 3D printing in the U.S., Canada, and Europe for this industry.

The WHO Model List of Essential Medicines (EML) prioritizes medicines that have significant global public health value. The EML can also deliver important messages on appropriate medicine use. Since 2017, in response to the growing challenge of antimicrobial resistance, antibiotics on the EML have been reviewed and categorized into three groups: Access, Watch, and Reserve, leading to a new categorization called AWaRe. These categories were developed taking into account the impact of different antibiotics and classes on antimicrobial resistance and the implications for their appropriate use. The 2023 AWaRe classification provides empirical guidance on 41 essential antibiotics for over 30 clinical infections targeting both the primary health care and hospital facility setting. A further 257 antibiotics not included on the EML have been allocated an AWaRe group for stewardship and monitoring purposes. This article describes the development of AWaRe, focussing on the clinical evidence base that guided the selection of Access, Watch, or Reserve antibiotics as first and second choices for each infection. The overarching objective was to offer a tool for optimizing the quality of global antibiotic prescribing and reduce inappropriate use by encouraging the use of Access antibiotics (or no antibiotics) where appropriate. This clinical evidence evaluation and subsequent EML recommendations are the basis for the AWaRe antibiotic book and related smartphone applications. By providing guidance on antibiotic prioritization, AWaRe aims to facilitate the revision of national lists of essential medicines, update national prescribing guidelines, and supervise antibiotic use. Adherence to AWaRe would extend the effectiveness of current antibiotics while helping countries expand access to these life-saving medicines for the benefit of current and future patients, health professionals, and the environment., (Copyright © 2024 World Health Organization.

Background: The mass gathering in Hajj (Islamic pilgrimage) makes the spread of infectious diseases inevitable. Antibiotics are frequently prescribed during this season. We aimed to measure antimicrobial utilization during the 2022 Hajj and evaluate the practice using quality indicators., Methods: Antimicrobial utilization by Hajj medical facilities (77 primary clinics and 7 hospitals) was measured using the anatomic therapeutic classification defined daily dose (DDD) and DDD/1,000-inhabitant/day (DID), where inhabitants were the Hajj 2022 pilgrims (n = 899,353). Quality indicators included percentages of consumption of different antibiotic classes of the total consumption of antibacterials for systemic use in DID., Results: During Hajj, there was 87,173 outpatient visits and 740 hospitalizations (215 critically ill). Amoxicillin was the most prescribed antibiotic (DID=11.708) followed by azithromycin (DID=7.395). Penicillins fell in the second quartile (i.e., highly prescribed) with a quality indicator value (J01&#95;CE%) of 48.149. The consumption of other antibacterials, including fluoroquinolones, fell in the first quartile (<25%). The overall ratio of broad- to narrow-spectrum antibiotic prescribing (J01&#95;B/N) was 1.49., Conclusion: Although the prescribing of β-lactams over fluoroquinolones indicates a good practice, clinicians should be reminded that most infections spreading in mass gatherings are viral; hence, do not require antibiotics. Implementation of antimicrobial stewardship is recommended to improve antimicrobial utilization., Competing Interests: Declaration of Competing Interest The authors declare no competing interests., (Copyright © 2023 The Authors.

This study intended to reduce prescriptions of antimicrobials for pharyngitis in a district general emergency department. “FeverPAIN” score has been found to reduce prescribing by 30%.Prescribing behaviours were examined in 2 separate periods before and after clinician education.The ‘no prescription’ strategy rose from 20% to 56% for low fever pain score. Immediate prescribing declined from 93% to 55% in the intermediate group, with one use of delayed prescription. Antimicrobial prescribing was down 29% overall.Clinicians reduced prescriptions for milder presentations, but delayed prescribing was underutilised. FeverPAIN scoring in secondary care is potentially efficacious when used correctly.

Background: The Stewardship Framework (Framework) was developed by an expert clinician group and was designed to provide a mechanism for continuous monitoring of improvement in opioid prescribing in acute hospitals. The aim of this study was to modify the Framework into an Opioid Stewardship Self-Assessment Tool (Self-Assessment Tool), and pilot test the acceptability and its use in a variety of acute hospital settings., Methods: The Framework was converted into the Self-Assessment Tool to allow hospitals to undertake a gap analysis of their current opioid stewardship activities. To participate hospitals were required to establish a small team and complete the Self-Assessment Tool. Participating sites were recruited using purposive sampling. Responses were tabulated and coded to enable assessment. 'Acceptability' was defined as the completion of the Self-Assessment Tool (response rate, proportion of questions answered) and responder feedback relating to its content. The use of the Tool was categorised based on the level of detail of responses., Results: Nineteen of the 20 facilities approached, agreed to participate. The 16 sites which established a small team to facilitate survey completion are included in the final analysis. The overall response rate was 96 % (413/432) for the (27 survey questions across 16 participating sites), 4 % (19/432) of questions were left unanswered or were not interpretable by the study team. Opportunities were identified to enhance the use of the Self-Assessment Tool, particularly to support its potential to assist reflection and planning of local strategies., Conclusion: This study demonstrated that the Self-Assessment Tool was an acceptable method of assessing a facility's opioid stewardship capabilities in a real-world setting. The next iteration will be modified using the insights on how the Tool was used by study participants., Competing Interests: Declaration of competing interest All authors have confirmed they have no sources of competing interests to declare., (Copyright © 2023 Elsevier Inc.

Introduction: Fighting against antimicrobial resistance is a current priority, and further efforts need to be made to improve antimicrobial prescribing and reduce the spread of infections in paediatric care settings., Methods: We conducted a prospective longitudinal study on the use of antimicrobials from the time the antimicrobial stewardship programme (ASP) was introduced in January 2016 to December 2017 (period 2 [P2]) in our children's hospital. We compared the obtained results on antimicrobial prescribing with retrospective data from the period preceding the introduction of the ASP (2014-2015, period 1 [P1]). The sample consisted of paediatric inpatients who received broad-spectrum antimicrobials, antifungals or intravenous antibiotherapy lasting more than 5 days. We compared the use of antimicrobials in P1 versus P2., Results: A total of 160 patients were included during P2. The antibiotics for which a recommendation was made most frequently were meropenem (41.6%) and cefotaxime (23.4%). In 45% of care episodes, the consultant recommended "no change" to the prescribed antimicrobial. The final rate of acceptance of received recommendations by the prescribing physicians was 89%. We found average decreases of 27.8% in the days of treatment per 1000 inpatient days and 22.9% in the number of antimicrobial starts per 1000 admissions in P2. The use of carbapenems, cephalosporins and glycopeptides decreased in P2 compared to P1. The average annual cost of antimicrobial treatment decreased from є150 356/year during P1 to є98 478/year in P2., Conclusion: Our ASP achieved a significant decrease in the use of broad-spectrum antibiotics and antifungals. The costs associated with antimicrobial prescribing decreased following the introduction of the ASP, which was a cost-effective action in this study period., (Copyright © 2023 Asociación Española de Pediatría.

Tourism as an economic activity has grown substantially and is increasingly adding to local and seasonal pressures on water supply systems of tourist destinations around the world. Based on data from the AQUASTAT and EarthCheck tourist accommodation databases, this research analysed tourism-related water use in 21 countries and compared it with other municipal use. Tourists׳ water use on a per guest night basis was found to differ substantially, with water usage being highest (up to 956 l per guest night in China) and most diverse in developing countries. The disparity between tourist water use and that of locals is also greatest in low or mid-income countries. Industrialised countries, in contrast, are characterised by high tourism water efficiencies, with no apparent discrepancy in water use between tourism and non-tourism users. Implications of this research for managing potential water conflicts and the need for broader tourist destination stewardship for water resources are discussed.

Background: Overuse or misuse of antimicrobials is common in pediatric intensive care units (PICU) and may be associated with poor clinical outcomes. Although an antimicrobial stewardship program (ASP) has been found to improve this practice, the required expertise in infectious diseases may be limited in some centers. We aimed to evaluate the effect of telehealth ASP on the rate of PICU antimicrobial use in a center without a local Infectious Diseases consultation service., Methods: A retrospective cohort study was performed between October 1st, 2018, and October 31st, 2020, in Farwaniya Hospital PICU, a 20-bed unit. All pediatric patients who were admitted to PICU and received systemic antimicrobials during the study period were included and followed until hospital discharge. The ASP team provided weekly prospective audit and feedback on antimicrobial use starting October 8th, 2019. A pediatric infectious diseases specialist joined the ASP rounds remotely. Descriptive analyses and a pre-post intervention comparison of days of therapy (DOT) were used to assess the effectiveness of the ASP intervention., Results: There were 272 and 156 PICU admissions received systemic antimicrobial before and after the initiation of ASP, respectively. Bronchiolitis and pneumonia were the most common admission diagnoses, together compromising 60.7% and 61.2% of cases pre- and post-ASP. The requirement for respiratory support was higher post-ASP (76.5% vs. 91.5%, p < 0.001). Average monthly antimicrobial use decreased from 922 (95%CI 745-1000) to 485 DOT/1000 patient-days (95%CI 246-722, P < 0.05). A decline in DOT was observed across most antibiotic classes, except for ceftriaxone. No effect on the length of PICU stay, length of hospitalization, or mortality was observed. Most (89.7%) ASP recommendations were followed either fully or partially., Conclusion: In settings where Infectious Diseases consultation services are unavailable, PICU telehealth ASP can be effectively implemented and associated with significantly reducing antimicrobial use., Competing Interests: Declaration of Competing Interest We have a competing interest to declare: Jesse Papenburg: AbbVie (Grant/Research Support, Other Financial or Material Support, Personal fees), AstraZeneca (personal fees), Medimmune (Grant/Research Support), Merck (Grant/Research Support, personal fees), and Seegene (Grant/Research Support, Other Financial or Material Support, Personal fees).

Abstract Objectives: The need to improve access to good health care for Aboriginal and Torres Strait Islander people has been the subject of policy debate for decades, but progress is hampered by complex policy and administrative arrangements and lack of clarity about the responsibilities of governments. This study aimed to identify the current legal basis of those responsibilities and define options available to Australian governments to enact enduring responsibility for Aboriginal health care. Methods: This study used a framework for public health law research and conducted a mapping study to examine the current legal underpinnings for stewardship and governance for Aboriginal health and health care. More than 200 pieces of health legislation were analysed in the context of the common and statutory law and health policy goals. Results: Very little specific recognition of the needs of Aboriginal people was found, and nothing that creates responsibility for stewardship and governance. The continuing absence of a legislative framework to address and protect Aboriginal health can be traced back to the founding doctrine of terra nullius (unoccupied land). Conclusions: We considered the results applying both a human rights perspective and the perspective of therapeutic jurisprudence. We suggest that national law for health stewardship would provide a strong foundation for progress, and should itself be based on recognition of Australia's First Peoples in the Australian Constitution, as is currently proposed.
