Antimicrobial stewardship programs in health care systems

mHealth Apps Available in Italy to Support Health Care Professionals in Antimicrobial Stewardship Implementation: Systematic Search in App Stores and Content Analysis

Background

Antimicrobial resistance (AMR) is a major challenge of the 21st century. Digital technologies are now an increasingly effective means of supporting optimal health care delivery and public health.

Objective

The aim of this study was to explore the apps available to support health care professionals in the fight against AMR.

Methods

A total of 4 independent researchers conducted a systematic search of the App Store and Google Play Store using the following keywords: "antimicrobial resistance," "antibiotic resistance," "antimicrobial stewardship," "antibiotic stewardship," "antibiotic guide," "antibiotic therapy," and "antimicrobial therapy." The same keywords were also searched in Italian. The apps whose contents were in languages other than Italian or English, or apps which were games, or had multimedia or paid content and advertising, or apps for only specific pathologies were not considered. A set of basic information was collected for all apps found. After downloading the apps, they were evaluated using an 86-item checklist containing expert-validated criteria aggregated in the domains of pathogens and etiological agents, diagnosis and therapy support, AMR, dashboard function, antimicrobial stewardship (AMS), notes and recordings, network, and technical characteristics of the app.

Results

First, 115 apps were identified: 31 apps for Android and 84 apps for iOS. By applying the exclusion criteria, 31 apps were excluded (16 for Android and 15 for iOS) for the following reasons: not available in Italian or English (6 apps), not freely available (14 apps), required registration (5 apps), and games (6 apps). The remaining 84 eligible apps (15 for Android and 69 for iOS) were downloaded, installed, and further analyzed using the same criteria, excluding 57 apps (48 for iOS and 9 for Android) for the following reasons: required further registration (16 apps), language other than Italian or English (17 apps), pathology specific (5 apps), paid content (8 apps), specific to veterinarians (4 apps), recreational apps (2 apps), referred to only scientific articles (1 app), no longer available (1 app), and not health care objectives (3 apps). The remaining 27 apps (6 for Android and 21 for iOS) were selected for in-depth analysis. Of the 27 apps that met the inclusion criteria, most apps did not fulfill the desirable aspects and only 2 of them achieved a fulfillment score of 36%. The highest scores were achieved for support for diagnosis and therapy (37%) and technical characteristics of the app (23%). Lower scores were achieved for AMS (8%), pathogens and etiological agents (4%), notes and records (3%), network (2%), AMR (1%), and dashboard function (1%).

Conclusions

None of the apps examined successfully provided the desired features and functions. To better engage of prescribers in the fight against AMR, the development of an app that meets the requirements is needed.

Artificial intelligence-driven approaches in antibiotic stewardship programs and optimizing prescription practices: A systematic review

Antimicrobial stewardship programs (ASPs) are essential in optimizing the use of antibiotics to address the global concern of antimicrobial resistance (AMR). Artificial intelligence (AI) and machine learning (ML) have emerged as promising tools for enhancing ASPs efficiency by improving antibiotic prescription accuracy, resistance prediction, and dosage optimization. This systematic review evaluated the application of AI-driven ASPs, focusing on their methodologies, outcomes, and challenges. We searched all of the databases in PubMed, Scopus, Web of Science, and Embase using keywords related to "AI" and "antibiotic." We only included studies that used AI and ML algorithms in ASPs, with the main criteria being empirical antibiotic selection, dose adjustment, and ASP adherence. There were no limits on time, setting, or language. Two authors independently screened studies for inclusion and assessed their risk of bias using the Newcastle Ottawa Scale (NOS) Assessment tool for observational studies. Implementation studies underscored AI's potential for improving antimicrobial stewardship programs. Two studies showed that logistic regression, boosted-tree models, and gradient-boosting machines could effectively describe the difference between patients who needed to change their antibiotic regimen and those who did not. Twenty-four studies have confirmed the role of machine learning in optimizing empirical antibiotic selection, predicting resistance, and enhancing therapy appropriateness, all of which have the potential to reduce mortality rates. Additionally, machine learning algorithms showed promise in optimizing antibiotic dosing, particularly for vancomycin. This systematic review aimed to highlight various AI models, their applications in ASPs, and the resulting impact on healthcare outcomes. Machine learning and AI models effectively enhance antibiotic stewardship by optimizing patient interventions, empirical antibiotic selection, resistance prediction, and dosing. However, it subtly draws attention to the differences between high-income countries (HICs) and low- and middle-income countries (LMICs), highlighting the structural difficulties that LMICs confront while simultaneously highlighting the progress made in HICs.

Evolution of pharmacist roles in antimicrobial stewardship: A 20-year systematic review

INTRODUCTION

Whilst pharmacists are recognized as key contributors to antimicrobial stewardship (AMS) programs, the extent of their participation varies in different countries. We report a systematic review of pharmacist roles in AMS over 20 years.

METHODS

A systematic review of the literature describing pharmacist-led or driven AMS and its outcomes published in English between January 01, 2000, and June 30, 2020, was conducted across the main databases for research publication.

RESULTS

The analysis included 111 papers, of which 77.5% (86/111) were from high-income countries (HIC) predominantly from the USA. While pharmacist-led or driven AMS interventions were reported only from HICs in the early 2000s, the review found a progressive rise in such studies from all income settings with audit and feedback being the most frequent intervention reported. Between 2016 and 2020, studies on pharmacists-led or driven outpatient AMS and interventions related to beta-lactam or penicillin allergy were reported from HICs. Key outcomes reported include improved appropriateness of antimicrobial therapy and decreased consumption of antimicrobials.

CONCLUSION

Existing evidence demonstrates the positive impact of pharmacists' involvement in AMS. There needs to be a concerted effort in facilitating pharmacist roles in AMS across all countries, irrespective of income setting.

Correlation between carbapenem susceptibility in Pseudomonas aeruginosa and modified antibiotic heterogeneity index: a multicenter observational study using a surveillance platform

Objective

This study focused on exploring the relationship between antimicrobial use indicators, including the modified antibiotic heterogeneity index (mAHI), and the carbapenem susceptibility in Pseudomonas aeruginosa.

Design

Survey-based observational study conducted across multiple facilities.

Setting

Public community hospital institutions.

Methods

This survey was conducted in 15 community hospitals in Japan. Indicators, such as the defined daily doses (DDDs), days of therapy (DOTs), antibiotic heterogeneity index (AHI), and mAHI, were analyzed for P. aeruginosa carbapenem susceptibility using Spearman's rank correlation. The predictive accuracies of the AHI and mAHI for carbapenem susceptibility were compared using DeLong's test for the 2 correlated receiver operating characteristic curves.

Results

No significant correlations were observed between DDDs or DOTs and carbapenem susceptibility. However, a significant correlation was observed between carbapenem susceptibility and the mAHI (r = 0.261, P = .02), which also demonstrated a higher predictive accuracy for high susceptibility rates than that of the AHI (area under the curve: 0.75 vs 0.58, p < .01). The optimal mAHI cutoff value for predicting 90% susceptibility was 0.765, with a sensitivity of 67.7% and specificity of 76.5%.

Conclusions

The mAHI may be a better predictor of carbapenem susceptibility than other commonly used indicators. This study underscores the utility of the mAHI as an effective indicator of antimicrobial usage patterns for managing carbapenem susceptibility in P. aeruginosa. Incorporating the mAHI into antimicrobial stewardship programs could enhance the effectiveness of antimicrobial interventions across diverse healthcare settings.

Escherichia coli: An arduous voyage from commensal to Antibiotic-resistance

Escherichia coli (E. coli), a normal intestinal microbiota is one of the most common pathogen known for infecting urinary tract, wound, lungs, bone marrow, blood system and brain. Irrational and overuse of commercially available antibiotics is the most imperative reason behind the emergence of the life threatening infections caused due to antibiotic resistant pathogens. The World Health Organization (WHO) identified antimicrobial resistance (AMR) as one of the 10 biggest public health threats of our time. This harmless commensal can acquire a range of mobile genetic elements harbouring genes coding for virulence factors becoming highly versatile human pathogens causing severe intestinal and extra intestinal diseases. Although, E. coli has been the most widely studied micro-organism, it never ceases to astound us with its ability to open up new research avenues and reveal cutting-edge survival mechanisms in diverse environments that impact human and surrounding environment. This review aims to summarize and highlight persistent research gaps in the field, including: (i) the transfer of resistant genes among bacterial species in diverse environments, such as those associated with humans and animals; (ii) the development of resistance mechanisms against various classes of antibiotics, including quinolones, tetracyclines, etc., in addition to β-lactams; and (iii) the relationship between resistance and virulence factors for understanding how virulence factors and resistance interact to gain a better grasp of how resistance mechanisms impact an organism's capacity to spread illness and interact with the host's defences. Moreover, this review aims to offer a thorough overview, exploring the history and factors contributing to antimicrobial resistance (AMR), the different reported pathotypes, and their links to virulence in both humans and animals. It will also examine their prevalence in various contexts, including food, environmental, and clinical settings. The objective is to deliver a more informative and current analysis, highlighting the evolution from microbiota (historical context) to sophisticated diseases caused by highly successful pathogens. Developing more potent tactics to counteract antibiotic resistance in E. coli requires filling in these gaps. By bridging these gaps, we can strengthen our capacity to manage and prevent resistance, which will eventually enhance public health and patient outcomes.

Efficacy and safety of vancomycin compared with those of alternative treatments for methicillin-resistant Staphylococcus aureus infections: An umbrella review

OBJECTIVE

To summarize the evidence on the efficacy and safety of vancomycin compared with those of alternative treatments in adult patients with methicillin-resistant Staphylococcus aureus (MRSA) infection.

METHODS

PubMed, Embase, and Web of Science were searched up to December 15, 2023, for systematic reviews and meta-analyses comparing vancomycin with alternative MRSA treatments. Primary outcomes included clinical cure and microbiological eradication rates. Organ-specific safety outcomes were assessed. Summary estimates were recalculated using a random-effects model. Evidence was graded using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool. This study was registered in PROSPERO (CRD42022340359).

RESULTS

This umbrella review included 19 studies and 71 meta-analyses (46 efficacy and 25 safety) comparing vancomycin with 10 alternative treatments across different MRSA infection types and populations. GRADE assessment showed that 29.58% of the meta-analyses were of high quality. Linezolid and daptomycin showed higher efficacy in MRSA-induced skin and soft tissue infections and pneumonia (moderate evidence quality) and bacteremia (very low evidence quality), respectively, compared with that of vancomycin. Cephalosporins had a higher risk of nausea, whereas linezolid had a higher risk of nausea, diarrhea, and thrombocytopenia than that of vancomycin. Vancomycin posed a higher risk of rash, pruritus, red man syndrome, and nephrotoxicity than that of alternatives.

CONCLUSIONS

The quality of evidence supporting the higher efficacy of alternative treatment over vancomycin for MRSA infection was not high. Given varying safety profiles and advancements in therapeutic monitoring, careful consideration of patient-specific factors and pharmacokinetics is crucial when selecting treatment alternatives to vancomycin.

Regional Variation in Urinary Escherichia coli Resistance Among Outpatients in Washington State, 2013-2019

Escherichia coli (E. coli) is a predominant pathogen of urinary tract infections (UTIs) in the United States. We analyzed resistance patterns by geographic location in Washington State to assess the need for regional antibiograms. The study included urinary E. coli antibiotic susceptibility tests performed by Quest Diagnostics on Washington outpatient isolates from 2013 to 2019. We conducted logistic regressions with robust standard errors for five antibiotics (ceftriaxone, ciprofloxacin, gentamicin, trimethoprim-sulfamethoxazole), with isolates classified as "susceptible" or "resistant" for each antibiotic tested. Analyses were adjusted for sex, year of isolate collection, and age group (0-18, 19-50, >50). The state's nine Public Health Emergency Preparedness Regions (PHEPRs) were used as the geographic level for the analysis. The analysis included 40,217 isolates (93% from females, mean age 47 years). Compared to the Central PHEPR (containing Seattle), most other regions had significantly lower adjusted prevalence ratios (aPORs) of antimicrobial resistance (AMR), with aPORs as low as 0.20 (95% CI: 0.06-0.63) for ceftriaxone in the North Central region. Additionally, no regions had significantly higher aPOR of resistance for any antibiotic. Differences in resistance between the Central and other regions varied by antibiotic with the largest difference for ceftriaxone and smallest for ampicillin. The finding of regional variation of E. coli AMR calls for more specific community antibiograms to enable a precise approach to antibiotic prescribing and stewardship.

Antibiotic Prescribing Practices in a Tertiary Care Teaching Hospital: A Retrospective Cross-Sectional Analysis

Background Antibiotics are among the most frequently prescribed medications in hospitals, yet a significant portion of their use is inappropriate, contributing to the growing global threat of antimicrobial resistance (AMR). In Pakistan, AMR has reached alarming levels with the rise of multi- and extensively drug-resistant bacteria. This study evaluates antibiotic prescribing practices and the use of culture sensitivity (CS) testing to assess the appropriateness of antibiotic therapy. Methods This cross-sectional retrospective study was conducted in a 500-bed tertiary care teaching hospital in Islamabad, Pakistan, analyzing inpatient records from 2020 to 2022. From over 5000 patient files, 1012 met the inclusion criteria and were reviewed. The study assessed the rationality of antibiotic prescriptions based on the evidence of infection (EoI), clinical parameters, and the presence or absence of CS testing. Statistical analyses, including Chi-square tests, logistic regression, and Cox proportional hazards regression, were applied to determine the association between antibiotic use and patient outcomes. Results Among the 1,012 patients analyzed, 91.8% (n = 929) received one or more antibiotics. However, 30% (n = 274) of these prescriptions were issued without any documented EoI. Only 17.5% of patients underwent CS testing. Patients exposed to five or more antibiotics had a 2.5-fold increased risk of ICU mortality (HR = 2.50, p < 0.001). A positive correlation (r = 0.42, p < 0.001) was found between the number of antibiotics prescribed and the length of hospitalization. Conclusion The findings of this study reveal a high rate of inappropriate antibiotics prescribed without EoI and CS testing. The results emphasize the urgent need for comprehensive Antibiotic Stewardship Programs (ASPs) in hospital settings, particularly focusing on mandatory CS testing protocols. By reducing irrational antibiotic use, these initiatives can significantly mitigate the rise of AMR globally, especially in resource-limited settings. Implementing ASPs not only optimizes antibiotic use but also aligns with the WHO recommendations, demonstrating the effectiveness of multifaceted interventions in minimizing resistance and improving patient outcomes.

Evaluating a virtual facilitation workshop with antimicrobial stewardship teams within a cluster randomized stepped-wedge trial

BACKGROUND

Antimicrobial stewardship programs (ASP) often function naturally as facilitators within clinical hospital settings, by working with individuals and teams to reduce unnecessary antibiotics. Within implementation science, facilitation has been studied and evaluated as an implementation strategy that can accelerate and improve fidelity to implementation efforts. This study describes a novel, virtual facilitation strategy developed and served as an intervention within the optimizing perioperative antibiotics for children trial (OPERATIC trial). This paper: (1) describes ASP team's preferences for and use of a facilitation workshop and (2) describes sustained use of facilitation skills throughout the study period.

METHODS

Study participants included antimicrobial stewardship team members from the nine children's hospitals that participated in this study and completed facilitation training. All individuals who completed facilitation training were asked to evaluate the training through an online survey. Additionally, site leads were interviewed by the site coordinator every other month and asked about their team's use of facilitation skills throughout the rest of the study period. Survey data were managed and coded in R, and qualitative interview data were analyzed using rapid methodology.

RESULTS

30 individuals, including both physicians and pharmacists, completed the evaluation. Individuals largely rated themselves as novice facilitators (53%). Individuals reported satisfaction with virtual facilitation and identified different components of the workshops as valuable. An additional 108 interviews were performed throughout the study period. These interviews found that facilitators reported using all skills throughout the study period and described varied use of skills over time. All nine sites applied facilitation strategies, team building techniques, and communication/conflict skills at some point during the intervention phase.

CONCLUSION

We describe the use of virtual facilitation as an acceptable and appropriate strategy to enhance facilitation skills for ASP teams working to reduce unnecessary postoperative antibiotics. Participants reported different useful components of facilitation training and described using differing facilitation skills throughout the trial. Overall, the use of facilitation skills continued throughout the duration of the study period. This paper outlines how facilitation training can be conducted virtually in a way that is feasible and acceptable to clinicians.

Community pharmacists' knowledge and practices towards antimicrobial stewardship: findings and implications

BACKGROUND

Antimicrobial stewardship (AMS) programmes have been implemented around the world to optimally manage antimicrobial use to attenuate antimicrobial resistance (AMR). This study assessed the knowledge and practices of community pharmacists towards AMS strategies in the Lusaka District, Zambia.

METHODS

This cross-sectional study was conducted among 194 community pharmacists in the Lusaka district using a structured questionnaire from August 2022 to September 2022. Data analysis was done using Statistical Package for Social Science (SPSS) version 22.0.

RESULTS

Of the 194 participants, 86% of the community pharmacists had good knowledge of AMS. The present study found that 83.5% were aware of AMS strategies used in community pharmacy practice. Further, 83.5% of the CPs were familiar with the goals of AMS and 89.2% believed that AMS was necessary for their pharmacy practice. Furthermore, 66.7% of the participants exhibited good practice towards the AMS strategies. Finally, 61.3% frequently avoided the use of broad-spectrum antimicrobials that were not necessary.

CONCLUSIONS

According to the findings of this study, the majority of community pharmacists had good knowledge of the AMS strategies that were employed to combat AMR; nonetheless, some of them had poor practices. Therefore, there is a need for community pharmacists to have access to sufficient ongoing professional development programmes and educational activities through AMS programmes to address AMR.

Towards integrated cross-sectoral surveillance of pathogens and antimicrobial resistance: Needs, approaches, and considerations for linking surveillance to action

Pathogenic and antimicrobial-resistant (AMR) microorganisms are continually transmitted between human, animal, and environmental reservoirs, contributing to the high burden of infectious disease and driving the growing global AMR crisis. The sheer diversity of pathogens, AMR mechanisms, and transmission pathways connecting these reservoirs create the need for comprehensive cross-sectoral surveillance to effectively monitor risks. Current approaches are often siloed by discipline and sector, focusing independently on parts of the whole. Here we advocate that integrated surveillance approaches, developed through transdisciplinary cross-sector collaboration, are key to addressing the dual crises of infectious diseases and AMR. We first review the areas of need, challenges, and benefits of cross-sectoral surveillance, then summarise and evaluate the major detection methods already available to achieve this (culture, quantitative PCR, and metagenomic sequencing). Finally, we outline how cross-sectoral surveillance initiatives can be fostered at multiple scales of action, and present key considerations for implementation and the development of effective systems to manage and integrate this information for the benefit of multiple sectors. While methods and technologies are increasingly available and affordable for comprehensive pathogen and AMR surveillance across different reservoirs, it is imperative that systems are strengthened to effectively manage and integrate this information.

Knowledge of antimicrobial stewardship and the Access, Watch and Reserve (AWaRe) classification of antibiotics among frontline healthcare professionals in Akwa Ibom State, Nigeria: a cross-sectional study

BACKGROUND

Antimicrobial stewardship (AMS) aims to improve antibiotic use while reducing resistance and its consequences. There is a paucity of data on the availability of AMS programmes in southern Nigeria. Further, there is no data on Nigerian healthcare professionals' knowledge of the WHO 'Access, Watch and Reserve' (AWaRe) classification of antibiotics. This study sought to assess knowledge of AMS and the AWaRe classification of antibiotics among frontline healthcare professionals in Akwa Ibom State, Nigeria.

METHODS

This was a cross-sectional survey of 417 healthcare professionals, comprising medical doctors, pharmacists and nurses, across 17 public hospitals in Akwa Ibom State, Nigeria. A paper-based self-completion questionnaire was used to collect data from the participants during working hours between September and November 2023. Statistical analysis was done using SPSS version 25.0, with p < 0.05 indicating statistical significance.

RESULTS

Four hundred and seventeen out of the 500 healthcare professionals approached agreed to participate, giving an 83.4% response rate. Most of the participants were female (62.1%) and nurses (46.3%). Approximately 57% of participants were familiar with the term antibiotic/antimicrobial stewardship, however, only 46.5% selected the correct description of AMS. Majority (53.0%) did not know if AMS programme was available in their hospitals. 79% of participants did not know about AWaRe classification of antibiotics. Among the 87 (20.9%) who knew, 28.7% correctly identified antibiotics into the AWaRe groups from a given list. Only profession significantly predicted knowledge of AMS and awareness of the AWaRe classification of antibiotics (p < 0.001). Pharmacists were more likely to define AMS correctly than medical doctors (odds ratio [OR] = 2.02, 95% confidence interval [CI] = 1.16-3.52, p = 0.012), whereas nurses were less likely to be aware of the WHO AWaRe classification of antibiotics than medical doctors (OR = 0.36, 95% CI = 0.18-0.72, p = 0.004).

CONCLUSIONS

There was a notable knowledge deficit in both AMS and the AWaRe classification of antibiotics among participants in this study. This highlights the need for educational interventions targeted at the different cadres of healthcare professionals on the role of AMS programmes in reducing antimicrobial resistance and its consequences.

Hospitalised patients as stewards of their own antibiotic therapy: a qualitative analysis informing the strategic design of interventions to encourage shared decision-making in tertiary hospital settings in Singapore

Background

Shared decision-making (SDM) on antibiotic therapy may improve antibiotic use in tertiary hospitals, but hospitalised patients are apprehensive about being involved in it. Understanding the facilitators and barriers to SDM can inform the design and implementation of interventions to empower these patients to engage in SDM on their antibiotic therapies.

Methods

We conducted qualitative interviews with 23 adult patients purposively sampled with maximum variation from the three largest tertiary-care hospitals in Singapore (April 2019─October 2020). Thematic analysis was conducted using the Theoretical Domains Framework and Capability, Opportunity, Motivation, Behaviour (COM-B) model to identify areas for intervention.

Results

Hospitalised patients lacked comprehensive knowledge of their antibiotic therapies and the majority did not have the skills to actively query their doctors about them. There was a lack of opportunities to meet and interact with doctors, and patients were less motivated to engage in SDM if they had a self-perceived paternalistic relationship with doctors, trusted their doctors to provide the best treatment, and had self-perceived poor knowledge to engage in SDM. To empower these patients, they should first be educated with antibiotic knowledge. Highlighting potential side effects of antibiotics could motivate them to ask questions about their antibiotic therapies. Environment restructuring, as facilitated by nurses and visual cues to nudge conversations, could create opportunities for interactions and motivating patients into SDM on their antibiotic therapies.

Conclusion

Education and environmental restructuring should be explored to empower hospitalised patients to engage in SDM on their antibiotic therapies.

Enhancing drug therapy in ostomy patients: Best practice recommendations for medication management

BACKGROUND

Ostomy surgery is a common procedure that poses various challenges for patients and healthcare professionals. There are numerous guidelines addressing different ostomy-related problems (ORPs) and supporting an interdisciplinary approach for ostomy care, but evidence-based literature for optimizing drug therapy after ostomy surgery is lacking.

AIM

To investigate and characterize typical ORPs in relation to drug therapy and provide best practice recommendations from a pharmaceutical point of view.

METHODS

Patients with an ileo- or colostomy were consecutively enrolled in a prospective, interventional monocentric cohort study during hospitalization, with particular attention to medication. A clinical pharmacist assessed DRPs by performing level 3 medication reviews and patient interviews. Pharmacists' interventions (PIs) were evaluated by two senior clinical pharmacists and documented in DokuPIK (Documentation of Pharmacists' Interventions in the Hospital). Following interdisciplinary discussions, physicians either accepted or rejected the proposed changes in drug therapy. Comparisons were made between ileostomy and colostomy patients regarding type and extent of PIs.

RESULTS

Out of the 80 patients included in the cohort, 54 (67.5%) had an ileostomy and 26 (32.5%) a colostomy. In this study, 288 PIs were documented (234 ileostomy vs. 54 colostomy), of wich 94.0% were accepted and implemented by the physicians. The most common reason for PIs in both subgroups (29.6% ileostomy vs. 26.1% colostomy) was a missing drug although indicated (e.g. no loperamide, but high stoma output). The proportion of PIs associated with the ostomy was higher in ileostomy patients (48.3% ileostomy vs. 31.5% colostomy; p = 0.025). Typical ORPs were extracted and analyzed as case studies including recommendations for their respective management and prevention.

CONCLUSION

This study highlights the importance of clinical pharmacists being a part of interdisciplinary teams to collaboratively improve ostomy care and patient safety. Especially ileostomy patients are more vulnerable for ORPs in the context of drug therapy and need to be monitored carefully.

Antimicrobial Stewardship Programs in Neonates: A Meta-Analysis

BACKGROUND AND OBJECTIVES

Neonatal sepsis is a significant contributor to mortality and morbidity; however, the uncontrolled use of antimicrobials is associated with significant adverse effects. Our objective with this article is to review the components of neonatal antimicrobial stewardship programs (ASP) and their effects on clinical outcomes, cost-effectiveness, and antimicrobial resistance.

METHODS

We selected randomized and nonrandomized trials and observational and quality improvement studies evaluating the impact of ASP with a cutoff date of May 22, 2023. The data sources for these studies included PubMed, Medline, Embase, Cochrane CENTRAL, Web of Science, and SCOPUS. Details of the ASP components and clinical outcomes were extracted into a predefined form.

RESULTS

Of the 4048 studies retrieved, 70 studies (44 cohort and 26 observational studies) of >350 000 neonates met the inclusion criteria. Moderate-certainty evidence reveals a significant reduction in antimicrobial initiation in NICU (pooled risk difference [RD] 19%; 95% confidence interval [CI] 14% to 24%; 21 studies, 27 075 infants) and combined NICU and postnatal ward settings (pooled RD 8%; 95% CI 6% to 10%; 12 studies, 358 317 infants), duration of antimicrobial agents therapy (pooled RD 20%; 95% CI 10% to 30%; 9 studies, 303 604 infants), length of therapy (pooled RD 1.82 days; 95% CI 1.09 to 2.56 days; 10 studies, 157 553 infants), and use of antimicrobial agents >5 days (pooled RD 9%; 95% CI 3% to 15%; 5 studies, 9412 infants). Low-certainty evidence reveals a reduction in economic burden and drug resistance, favorable sustainability metrices, without an increase in sepsis-related mortality or the reinitiation of antimicrobial agents. Studies had heterogeneity with significant variations in ASP interventions, population settings, and outcome definitions.

CONCLUSIONS

Moderate- to low-certainty evidence reveals that neonatal ASP interventions are associated with reduction in the initiation and duration of antimicrobial use, without an increase in adverse events.

Determination of the Enablers and Challenges in the Implementation of Pharmacy-based Antimicrobial Stewardship (AMS) Program in a Level 3 Hospital in Manila

Background and Objectives

Antimicrobial resistance (AMR) is a global public health threat that results from misuse and overuse of antimicrobials. The Department of Health (DOH) institutionalized the Antimicrobial Stewardship (AMS) Program in hospitals, based on the core elements (1) Leadership, (2) Policies, Guidelines, and Pathways, (3) Surveillance Antimicrobial Use (AMU) & AMR, (4) Action, (5) Education, and (6) Performance Evaluation to ensure rational use of antimicrobials and improve patient outcomes. The program implementation will require the involvement of the AMS clinical pharmacist to positively influence the success of the program's implementation. This study aims to identify the enablers and challenges as perceived by AMS clinical pharmacists in the implementation of an AMS program in a level 3 hospital in Manila.

Methods

A quantitative descriptive study design was employed by administering an online 50-item survey questionnaire to AMS pharmacists, who have at least six (6) months of experience as an AMS pharmacist in the hospital. The survey questionnaire was validated by an expert consultant and underwent pre-testing (Cronbach α = 0.983) for acceptable internal consistency. Responses were collated, coded, and analyzed using median values and frequency distributions for each questionnaire item per Department of Health (DOH) Core Element. Items garnering a median of >3.50 up to 5 were considered as perceived enablers, while those ≤3.50 were identified as perceived challenges.

Results

Some perceived enablers by the AMS pharmacists include presence of a leader and/or clinician in the AMS team, Information Technology (IT) resource availability, clear roles of AMS pharmacists, readily available hospital AMS guidelines, engagement in AMR and AMU surveillance activities, regular performance of AMS interventions (e.g., IV-to-PO conversion, dose optimization, de-escalation of broad spectrum), regular monitoring and evaluating of prescriptions and prescribing behavior, and continuous education on infection, prevention, and control (IPC) and hygiene. On the other hand, some perceived challenges include insufficient funding, inadequate knowledge in interpreting antibiograms, lack of adequate and specialized training sessions, lack of coordination with medical and nursing staff to ensure timely drug administration and automatic stop order, prescribing of non-Philippine National Formulary (PNF) antimicrobials, lack of time to perform AMS activities, lack of qualified personnel, and lack of hospital management and information technology (IT) support.

Conclusion

Empowering AMS clinical pharmacists is vital to addressing the perceived challenges and maximizing the perceived enablers to ensure the successful implementation of the AMS program in the hospital.

Impact of mandatory indications for outpatient antibiotic orders on accurate tracking of antibiotic indications

OBJECTIVE

We sought to evaluate whether implementing mandatory indications for outpatient electronic antibiotic orders or using encounter International Classification of Diseases, Tenth Revision (ICD10) codes more accurately reflected clinicians' charted diagnosis in encounter notes. Secondarily, we examined the appropriateness of antibiotic prescriptions.

DESIGN

Cross-sectional study.

METHODS

Mandatory indications were added to all outpatient electronic antibiotic orders on May 18, 2022. A randomly selected convenience sample of 1300 outpatient encounters with antibiotics from walk-in clinics was reviewed. Adjusted logistic regression was used to compare the congruence between encounter ICD10 code and charted diagnosis for encounters from July 15 to September 15, 2021 (pre-implementation period) to the congruence between encounter ICD10 code, charted diagnosis, and mandatory indication for encounters from July 15 to September 15, 2022 (post-implementation period). Antibiotic appropriateness based on charted diagnosis was also evaluated.

RESULTS

Among 1300 outpatient encounters, congruence between charted diagnosis and ICD10 code significantly increased in the post-implementation period (87.7% (565/644)) versus pre-implementation (83.3% (540/648), adjusted odds ratio (aOR) 1.52; 95% CI 1.03-2.25). Congruence between charted diagnosis and mandatory indication during post-implementation was 95.2% (613/644) and >5 times more likely to be congruent than charted diagnosis and ICD10 code during pre-implementation (aOR 5.45; 95% CI 3.26-9.11). Antibiotic prescribing based on charted diagnosis was twice as likely to be appropriate in the post-implementation period (aOR1.99; 95% CI 1.32-2.98).

CONCLUSIONS

Mandatory indications within antibiotic orders show better congruence with charted diagnosis than ICD10 codes and may increase antibiotic appropriateness and congruence between ICD10 code and charted diagnosis.

Randomized control trial on impact of clinical pharmacist led interventions on antibiotic stewardship program in children 0 to 18 years age in a tertiary care hospital in southern India

A prospective randomized controlled interventional study was conducted at a quaternary care multispecialty hospital in South India with the primary objective of identifying opportunities to improve antibiotic prescribing patterns in neonates, children, and adolescents. The hospital has a robust clinical pharmacist program wherein antibiotic prescriptions were checked for appropriateness of antibiotic dose, route, formulation, duration of therapy, and IV to oral switch. These characteristics of antibiotic use were therefore similar in the 75 children in the control and 75 in the intervention group. The additional clinical pharmacist interventions analyzed in this study included checking if a provisional diagnosis had been made before initiating antibiotics, ensuring that appropriate cultures were sent before starting antibiotics, time taken to optimize antibiotic therapy in accordance to the culture sensitivity report and whether the indication for antibiotics use was as per Indian Acdemy of Pediatrics (IAP) Drug Formulary recommendations. The main outcomes were that all these parameters except the first (all children had a clinical diagnosis before initiating antibiotic/s) were better in the intervention group and there was a significant reduction in the total antibiotic days, an increase in antibiotic-free days, and an improvement in the appropriateness of duration of antibiotic therapy and frequency of the antibiotic dosing. However, since the incidence of severe sepsis was higher in the intervention group, broad-spectrum and restricted antibiotics were used, and thus treatment costs were higher in this group. The results indicate that despite already existing clinical pharmacist interventions, additional ones could further improve antibiotic prescription accuracy significantly; and re-emphasized the need to employ trained pediatric general and subspecialty clinical pharmacists in sufficient numbers to implement a successful pediatric antibiotic stewardship program in a hospital.

Introduction of Unit-Dose Care in the 1,125 Bed Teaching Hospital: Practical Experience and Time Saving on Wards

Purpose

The shortage of nursing staff as well as the slow progress in the German health care system's digitalisation has gained much attention due to COVID-19. Patient-specific medication management using the unit-dose dispensing system (UDDS) has the potential for a lasting and positive influence on both digitalisation and the relief of nursing staff.

Methods

Nursing staff UDDS-acceptance was determined via a validated online survey. For the evaluation of stock keeping on the wards, the delivery quantities were determined for a comparative period before and after the introduction of the UDDS. The time required for on-ward medication-related processes on ward before and after the introduction of UDDS was recorded based on a survey form and the nursing relief in full-time equivalent (FTE) was calculated using the data obtained.

Results

We show that nurses appreciate the UDDS and confirm a significant reduction in drug stocks on the wards. The UDDS reduces the time needed to dispense medications from 4.52 ± 0.35 min to 1.67 ± 0.15 min/day/patient. In relation to the entire medication process, this corresponds to a reduction of 50% per day and per patient. Based on 40,000 patients/year and a supply of 1,125 beds with unit-dose blisters, 7.36 FTE nursing staff can be relieved per year. In contrast, 6.5 FTE in the hospital pharmacy are required for supplying the hospitals.

Conclusion

UDDS is well accepted by nurses, reduces stock levels on ward, and fulfils criteria as a nursing-relief measure.

Hospital prescribing patterns of antibiotics in Zambia using the WHO prescribing indicators post-COVID-19 pandemic: findings and implications

Background

Antimicrobial resistance (AMR) is a global public health problem that is fuelled by the inappropriate prescribing of antibiotics, especially those from the 'watch' and 'reserve' antibiotic lists. The irrational prescribing of antibiotics is particularly prevalent in developing countries, including Zambia. Consequently, there is a need to better understand prescribing patterns across sectors in Zambia as a basis for future interventions. This study evaluated the prescribing patterns of antibiotics using the WHO prescribing indicators alongside the 'access, watch and reserve' (AWaRe) classification system post-COVID pandemic at a faith-based hospital in Zambia.

Methods

A cross-sectional study was conducted from August 2023 to October 2023 involving the review of medical records at St. Francis' Mission Hospital in Zambia. A WHO-validated tool was used to evaluate antibiotic prescribing patterns alongside the AWaRe classification tool.

Results

Out of 800 medical records reviewed, 2003 medicines were prescribed. Each patient received an average of 2.5 medicines per prescription. Antibiotics were prescribed in 72.3% of encounters, of which 28.4% were injectable. The most frequently prescribed antibiotics were amoxicillin (23.4%-access), metronidazole (17.1%-access), ciprofloxacin (8%-watch) and ceftriaxone (7.4%-watch), with 77.1% overall from the 'access' list. Encouragingly, 96.5% of the medicines were prescribed by their generic names and 98% were from the Zambia Essential Medicines List.

Conclusions

There were high rates of antibiotic prescribing, including injectable antibiotics, which needs addressing going forward. It is crucial to implement targeted measures, including antimicrobial stewardship programmes, to improve future antibiotic prescribing in Zambia and reduce the risk of AMR.

Innovative Approaches to Monitor Central Line Associated Bloodstream Infections (CLABSIs) Bundle Efficacy in Intensive Care Unit (ICU): Role of Device Standardized Infection Rate (dSIR) and Standardized Utilization Ratio (SUR)-An Italian Experience

In several settings, the COVID-19 pandemic determined a negative impact on the occurrence of healthcare-associated infection, particularly for on central lines associated bloodstream infections (CLABSI). In our setting, we observed a significant increase in CLABSI in our intensive care unit (ICU) during 2020 and 2021 vs. 2018 to 2019. A refresher training activity on central venous catheter (CVC) management bundles was carried out in September-October 2021 for the ICU health staff. We assessed the impact of bundle implementation by means of standardized indicators, such as the Device Utilization Ratio (DUR), in this case, the Central Line Utilization Ratio, the Standardized Utilization Ratio (SUR), and the device Standardized Infection Ratio (dSIR). Standardized ratios for device use and infection ratio were computed using data from 2018 and 2019 as expectation data. After bundle implementation, we observed a significant reduction of dSIR (p < 0.001), which dropped from 3.23 and 2.99 in the 2020-2021 biennium to 1.11 in 2022 (CLABSI in the first quarter only); no more CLABSI were observed afterwards. Standardized ratios proved helpful in identify increasing trends of CLABSI in the ICU and monitoring the impact of a simple effective tool, i.e., training on and implementation of a bundle for CVC management.

Prescribing of antivirals for COVID-19 in a South Australian local health network according to statewide guidelines

Antiviral drugs were rapidly implemented into clinical practice for the treatment of high-risk patients with COVID-19, prompting the development of statewide guidelines. This South-Australian study reviewed guideline adherence, assessed prescribing patterns and highlighted the inappropriate management of relative drug-drug interactions and dosing for renal function. Additionally, it evaluated the impact of inappropriate antiviral drug use and suggested methods to improve quality use of medicines.

Impact of Antimicrobial Stewardship on Reducing Antimicrobial Resistance

Antimicrobial resistance has become a serious global issue, posing a significant threat to public health and healthcare professionals. Since the advent of penicillin, many antibiotics have lost their effectiveness in combating microbes simply due to inappropriate, irrational, unnecessary, and unrestricted use. The ineffectiveness of an increasing number of antibiotics necessitates the utilization of more potent antimicrobial agents for combatting uncomplicated infections. In response to the escalating prevalence of multidrug-resistant pathogens and the imperative to curtail the demand for novel antibiotics, the Antimicrobial Stewardship Program was conceived and implemented. This initiative is characterized by a lead physician, ideally possessing expertise in infectious diseases, alongside a pharmacist serving as a secondary leader and a microbiologist with defined responsibilities to achieve several objectives. These objectives include reducing indiscriminate usage of antimicrobial agents, promoting selective antimicrobial utilization based on culture results, de-escalating therapy from broad-spectrum to targeted antimicrobial agents, and transitioning from parenteral to oral administration when feasible. These objectives are pursued through a combination of pre-prescription and post-prescription strategies. While the Antimicrobial Stewardship Program is widely established in developed nations, a pressing need exists for its more comprehensive implementation in less developed regions. This review aims to examine the strategies used in antimicrobial stewardship programs to evaluate their effectiveness in preventing the development of multidrug-resistant organisms (MDROs) based on existing research studies. Under the Antimicrobial Stewardship Program, education of healthcare professionals and continuous disposal of information about antimicrobial resistance have helped to restrict the emergence of multidrug-resistant organisms.

A national antimicrobial guide with local, customizable versions: how is it used? A two-year analysis

Objectives

Guideline adherence is one of the most important objectives for antibiotic stewardship. The Dutch Working Party on Antibiotic Policy (SWAB) developed an online national guide (SWAB-ID) in 2006. Every Dutch hospital is offered the opportunity to customize the national version to their local context and distribute it through an independent website. We studied user data to see how often the guidelines on therapy, prophylaxis and medication are used.

Methods

Data on usage between 19 June 2020 and 30 June 2022 were extracted through Google Analytics for the national site and the 53 hospitals using a customized version of the national guide. User data were divided into three main groups: users of the national guide SWAB-ID, and users of the sites of general hospitals and university hospitals.

Results

A total of 1 837 126 searches were analysed, of which 1 393 681 (75.9%) concerned therapy, 111 774 (6.1%) prophylaxis and 331 671 (18%) medication. Of these searches, 456 854 (24.9%) were performed on the national site, 950 887 (51.8%) by general hospitals and 429 385 (23.4%) by university hospitals. The most commonly searched tracts among all user groups were lower respiratory tract (21.8%), kidney and urinary tract (16.6%) and skin and soft tissues (11.8%). The most commonly searched conditions were community-acquired pneumonia (15.3%), cystitis (13.5%) and sepsis (11.3%). The top ranked pages on medication differed for the three categories of users.

Conclusions

The SWAB-ID antimicrobial guide is used extensively by both general and university hospitals. The online guide can help in prescribing therapy according to the guideline.

Frequent screening for asymptomatic chlamydia and gonorrhoea infections in men who have sex with men: time to re-evaluate?

There is increasing debate regarding the harms and benefits of frequent asymptomatic screening for Chlamydia trachomatis and Neisseria gonorrhoeae in men who have sex with men (MSM). One concern is that frequent asymptomatic screening could result in increased antimicrobial resistance in an array of sexually acquired infections and other pathogens, due to selection pressure exerted by frequent broad-spectrum antimicrobial usage within some sexual networks. Here, we outline the harms and benefits of frequent C trachomatis and N gonorrhoeae screening in MSM in high-income settings and propose that screening frequency be reduced. We describe the evidence gaps that should be further explored to better understand the implications of reducing the frequency of asymptomatic C trachomatis and N gonorrhoeae screening in MSM and the surveillance systems that should be in place to prepare for such changes.

Origin of Antibiotics and Antibiotic Resistance, and Their Impacts on Drug Development: A Narrative Review

Antibiotics have revolutionized medicine, saving countless lives since their discovery in the early 20th century. However, the origin of antibiotics is now overshadowed by the alarming rise in antibiotic resistance. This global crisis stems from the relentless adaptability of microorganisms, driven by misuse and overuse of antibiotics. This article explores the origin of antibiotics and the subsequent emergence of antibiotic resistance. It delves into the mechanisms employed by bacteria to develop resistance, highlighting the dire consequences of drug resistance, including compromised patient care, increased mortality rates, and escalating healthcare costs. The article elucidates the latest strategies against drug-resistant microorganisms, encompassing innovative approaches such as phage therapy, CRISPR-Cas9 technology, and the exploration of natural compounds. Moreover, it examines the profound impact of antibiotic resistance on drug development, rendering the pursuit of new antibiotics economically challenging. The limitations and challenges in developing novel antibiotics are discussed, along with hurdles in the regulatory process that hinder progress in this critical field. Proposals for modifying the regulatory process to facilitate antibiotic development are presented. The withdrawal of major pharmaceutical firms from antibiotic research is examined, along with potential strategies to re-engage their interest. The article also outlines initiatives to overcome economic challenges and incentivize antibiotic development, emphasizing international collaborations and partnerships. Finally, the article sheds light on government-led initiatives against antibiotic resistance, with a specific focus on the Middle East. It discusses the proactive measures taken by governments in the region, such as Saudi Arabia and the United Arab Emirates, to combat this global threat. In the face of antibiotic resistance, a multifaceted approach is imperative. This article provides valuable insights into the complex landscape of antibiotic development, regulatory challenges, and collaborative efforts required to ensure a future where antibiotics remain effective tools in safeguarding public health.

The burden of hospital acquired infections and antimicrobial resistance

The burden of Hospital care-associated infections (HCAIs) is becoming a global concern. This is compounded by the emergence of virulent and high-risk bacterial strains such as "ESKAPE" pathogens - (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter species), especially within Intensive care units (ICUs) that house high-risk and immunocompromised patients. In this review, we discuss the contributions of AMR pathogens to the increasing burden of HCAIs and provide insights into AMR mechanisms, with a particular focus on last-resort antibiotics like polymyxins. We extensively discuss how structural modifications of surface-membrane lipopolysaccharides and cationic interactions influence and inform AMR, and subsequent severity of HCAIs. We highlight some bacterial phenotypic survival mechanisms against polymyxins. Lastly, we discuss the emergence of plasmid-mediated resistance as a phenomenon making mitigation of AMR difficult, especially within the ICUs. This review provides a balanced perspective on the burden of HCAIs, associated pathogens, implication of AMR and factors influencing emerging AMR mechanisms.

Quality indicators of hospitalized children influenced by clinical pharmacist services: A systematic review

BACKGROUND

Care for children who are hospitalized can be optimized if the pharmacist, in conjunction with the multidisciplinary team, promotes the rational use of medicines. In this sense, the evaluation of the quality of these clinical services through indicators is important in the planning, decision making of pharmacists and managers of these services.

OBJECTIVE

To characterize which health indicators were influenced by the pharmaceutical clinical services for the care of children in hospitals.

METHODS

A systematic review was performed. The search for data was made on the bases: Cochrane, Embase, Lilacs, Pubmed and Web of Science. Then, the search included studies in which evaluated the impact of pharmaceutical clinical services on clinical, economic and humanistic outcomes.

RESULTS

The search resulted in 11 included studies. In this review, four pharmaceutical clinical services were found: pharmacotherapy review, multiprofessional team interventions, antimicrobial stewardship program and pharmaceutical services at discharge hospital. The most influenced outcome indicators were length of hospital stay, with average time in the group that received the pharmacotherapy review service, and interventions multiprofessional team with a 6.45-day vs. 10.83 days in the control group; hospital readmissions with a significant reduction of non-scheduled readmission of 30 days in the ntimicrobial stewardship program; reduction of hospital costs and caregiver satisfaction.

CONCLUSION

In this study, we can highlight that pharmacotherapy review, multiprofessional team interventions and Antimicrobial Stewardship Program that significantly reduced the clinical results of length of hospital stay and hospital readmission, as well as a significant reduction of hospital costs.

Exploring drivers and challenges influencing antibiotic prescribing in outpatient settings and possible mitigation strategies in the United Arab Emirates: a qualitative study

Objectives

Healthcare institutions implement antimicrobial stewardship (AMS) programmes to optimize the use of antibiotics. The focus is often on inpatient rather than outpatient settings. We aimed to explore perceptions of AMS stakeholders on effective interventions for appropriate antibiotic use in outpatient settings, and the role of clinical pharmacists in the AMS multidisciplinary team.

Methods

A qualitative semi-structured interview study using thematic analysis by two researchers independently. Participants that practice AMS programmes were recruited from healthcare facilities in the United Arab Emirates (UAE). Interviews were conducted face to face or online and transcribed verbatim.

Results

Four themes emerged: (i) Perceived factors leading to unnecessary or inappropriate antibiotic prescribing and their impact on patients and the community; (ii) current outpatient AMS activities and perceived barriers and facilitators for their sustainability; (iii) suggested outpatient AMS strategies to be implemented in outpatient settings; and (iv) perceived future AMS implementation barriers and suggested mitigation strategies.

Conclusions

Several AMS interventions, together with the presence of a clinical pharmacist, may be effective in improving antibiotic use in UAE outpatient settings. Future research should investigate the most appropriate AMS strategy considering barriers and possible mitigation strategies to ensure sustainability.

Situational analysis of antimicrobial stewardship program (ASP) among public and private sector tertiary care hospitals in Karachi, Pakistan: A qualitative case study

Objective

To assess the current status of implementation of the Antimicrobial Stewardship Program (ASP) across Tertiary Care Hospitals in Karachi, Pakistan.

Design

Exploratory qualitative case study.

Setting

Public and private tertiary care hospitals in Karachi, Pakistan.

Participants and Methods

The study data were collected from 3 public and 4 private tertiary care hospitals. Twenty-eight in-depth interviews were conducted from the Chief Executive Officer, Chief Medical Officer, Medical Superintendent, and departmental heads of internal medicine, general surgery, and pediatric, respectively. Purposive sampling was done to include higher and middle managers, whereas the infectious diseases consultant, infectious diseases/clinical pharmacist, and clinical microbiologist were interviewed through snowball sampling methodology. Analysis was done using NVivo. Data were source-triangulated within and among the study setting and study participants.

Results

We found that more than two-thirds (n = 5, 71%) of tertiary care hospitals in Karachi do not have a structured ASP which includes major public sector hospitals (n = 3, 43%) and half of the private sector hospitals (n = 4, 29%). The study results led to four broad themes, (1) ASP structure, (2) ASP interventions, (3) hospital medical record-keeping system, and (4) structured way for analyzing and reporting mechanism of data related to the ASP. At H1 and H2, there was a consistency in ASP structure and interventions, whereas paucity seen among remaining tertiary care hospitals.

Conclusion

There is an alarming need for ASP in the public and private sector hospitals in Karachi. This study can inform future stakeholders regarding ASP and strategies for structural change at hospitals.

Misconceptions and Knowledge Gaps on Antibiotic Use and Resistance in Four Healthcare Settings and Five European Countries-A Modified Delphi Study

Misconceptions and knowledge gaps about antibiotics contribute to inappropriate antibiotic use and antimicrobial resistance. This study aimed to identify and prioritize misconceptions and knowledge gaps about antibiotic use from a healthcare professionals' perspective. A modified Delphi study with a predefined list of statements, two questionnaire rounds, and an expert meeting was conducted. The statements were rated by healthcare professionals from France, Greece, Lithuania, Poland, and Spain, and from general practice, out-of-hour services, nursing homes, and pharmacies. A total of 44 pre-defined statements covered the following themes: (1) antimicrobial resistance in general, (2) use of antibiotics in general, (3) use of antibiotics for respiratory tract infections, and (4) use of antibiotics for urinary tract infections. Consensus was defined as ≥80% agreement between the professionals during the second Delphi round. For 30% of the statements, professionals from the four settings together reached consensus. In each setting individually, at least 50% of the statements reached consensus, indicating that there are still many misconceptions and knowledge gaps that need to be addressed. Six educational tools (leaflets, posters, checklists) were developed to address the knowledge gaps and misconceptions. These can be used by patients and healthcare professionals to improve the use of antibiotics in practice.

Acculturation and Subjective Norms Impact Non-Prescription Antibiotic Use among Hispanic Patients in the United States

Using antibiotics without medical guidance (non-prescription antibiotic use) may contribute to antimicrobial resistance. Hispanic individuals are a growing demographic group in the United States (US) with a high prevalence of non-prescription antibiotic use. We investigated the effects of acculturation and subjective norms on Hispanic individuals' intentions to use antibiotics without a prescription from the following sources: (1) markets in the United States (not legal), (2) other countries (abroad), (3) leftovers from previous prescriptions, and (4) friends/relatives. We surveyed self-identified Hispanic outpatients in eight clinics from January 2020 to June 2021 using the previously validated Short Acculturation Scale for Hispanics (SASH). Of the 263 patients surveyed, 47% reported previous non-prescription use, and 54% expressed intention to use non-prescription antibiotics if feeling sick. Individuals with lower acculturation (Spanish-speaking preferences) expressed greater intentions to use antibiotics from abroad and from any source. Individuals with more friends/relatives who obtain antibiotics abroad were over 2.5 times more likely to intend to use non-prescription antibiotics from friends/relatives (p = 0.034). Other predictors of intention to use non-prescription antibiotics included high costs of doctor visits and perceived language barriers in the clinic. Antibiotic stewardship interventions in Hispanic communities in the United States should consider the sociocultural and healthcare barriers influencing non-prescription use and promote language-concordant healthcare.

An Overview of Preventive Strategies and the Role of Various Organizations in Combating Antimicrobial Resistance

The rise of antimicrobial resistance (AMR) is a major global public health threat due to excessive and inappropriate use of antibiotics and is responsible for prolonged illness, longer hospital stays, and economic burden to society. This article aims to review the factors, role of antimicrobial stewardship, preventive strategies, and role of various organizations in combating AMR. Three major factors of AMR are inappropriate and excessive utilization of antibiotics, nonadherence to infection control measures, and the emergence of pathogens that are resistant to multiple drugs. Antimicrobial stewardship initiatives play a vital role in promoting judicious and targeted utilization of antimicrobials, thereby safeguarding their efficacy and mitigating the emergence of resistance. Implementing such programs optimizes patient outcomes by ensuring that individuals receive the most suitable therapeutic interventions. International organizations have a vital role to play in addressing AMR by promoting the responsible use of antimicrobials, developing new drugs, and improving surveillance systems. As AMR's impact grows, it is critical to take a collaborative and interdisciplinary approach to mitigate its consequences effectively.

Increase in the community circulation of ciprofloxacin-resistant Escherichia coli despite reduction in antibiotic prescriptions

BACKGROUND

Community circulating gut microbiota is the main reservoir for uropathogenic Escherichia coli, including those resistant to antibiotics. Ciprofloxacin had been the primary antibiotic prescribed for urinary tract infections, but its broad use has been discouraged and steadily declined since 2015. How this change in prescriptions affected the community circulation of ciprofloxacin-resistant E. coli is unknown.

METHODS

We determined the frequency of isolation and other characteristics of E. coli resistant to ciprofloxacin in 515 and 1604 E. coli-positive fecal samples collected in 2015 and 2021, respectively. The samples were obtained from non-antibiotic-taking women of age 50+ receiving care in the Kaiser Permanente Washington healthcare system.

RESULTS

Here we show that despite a nearly three-fold drop in the prescription of ciprofloxacin between 2015 and 2021, the rates of gut carriage of ciprofloxacin-resistant E. coli increased from 14.2 % to 19.8% (P = .004). This is driven by a significant increase of isolates from the pandemic multi-drug resistant clonal group ST1193 (1.7% to 4.2%; P = .009) and isolates with relatively few ciprofloxacin-resistance determining chromosomal mutations (2.3% to 7.4%; P = .00003). Though prevalence of isolates with the plasmid-associated ciprofloxacin resistance dropped (59.0% to 30.9%; P = 2.7E-06), the isolates co-resistance to third generation cephalosporins has increased from 14.1% to 31.5% (P = .002).

CONCLUSIONS

Despite reduction in ciprofloxacin prescriptions, community circulation of the resistant uropathogenic E. coli increased with a rise of co-resistance to third generation cephalosporins. Thus, to reduce the rates of urinary tract infections refractory to antibiotic treatment, greater focus should be on controlling the resistant bacteria in gut microbiota.

Bacterial Contamination of Mobile Phones Used by Healthcare Workers in Critical Care Units: A Cross-Sectional Study from Saudi Arabia

BACKGROUND

Healthcare-associated infections (HAIs) present a formidable challenge for healthcare institutions, resulting in heightened mortality, morbidity, and economic burden. Within healthcare settings, various equipment and materials, including mobile phones, can potentially act as sources of infection. This study sought to examine the occurrence of bacterial contamination on mobile phones utilized by healthcare workers (HCWs) in intensive care units (ICUs), pediatric intensive care units (PICUs), neonatal intensive care units (NICUs), and cardiac care units (CCUs) within a central hospital (CH) and two peripheral hospitals (PHs) situated in the southwestern province of Saudi Arabia.

MATERIALS AND METHODS

We collected a total of 157 samples from mobile phones utilized by HCWs across all ICUs in the CH and PHs. These samples underwent bacteriological analysis to evaluate the degree of bacterial contamination.

RESULTS

We found that 45 out of 55 samples from physicians (81.81%) and 58 out of 77 samples from nurses (75.32%) showed bacterial contamination. Contamination rates on HCWs' mobile phones in the ICU, PICU, and NICU departments of the CH were observed at 69.56%, 80.95%, and 70.27%, respectively. Furthermore, the overall contamination rates in the ICUs, NICUs, and CCUs of the PHs were 78.26%, 88.88%, and 66.66%, respectively. The overall contamination rates of mobile phones in the CH and PHs were 72.11% and 81.13%, respectively.

CONCLUSION

These findings underscore the necessity of routinely disinfecting the mobile phones of HCWs to mitigate the risk of cross-contamination. Implementing robust disinfection protocols can significantly contribute to curtailing the propagation of bacterial pathogens and reducing the incidence of HAIs in healthcare settings.

Behavioral Components and Context of Antimicrobial Prescription in a Tertiary Hospital in Portugal

Consumption of antimicrobials is an important driver of antimicrobial resistance. There is limited knowledge of the key determinants of antimicrobial prescribing behavior in hospitals. An understanding of these determinants is required for the successful design, adoption, and implementation of quality improvement interventions in Antimicrobial Stewardship Programs (ASP). This study aimed to describe the main factors that influence the doctor's decision on antimicrobials prescribing and to identify the behaviors that drive physicians' decision making. A structured web-based questionnaire focused on behavioral components of antimicrobial prescription was applied to the medical staff of three different departments-Internal Medicine, General Surgery, and Intensive Care Medicine-of a university hospital. All doctors agreed that inadequate use of antimicrobials increases AMR. A total of 77% of the surgeons and 100% of the internists and intensivists perceived antimicrobial prescription as a priority in the department. Full autonomy in antimicrobial prescription was preferred by internists (64%) but not by surgeons (18%) and intensivists (24%). Most physicians were keen to have ASP advice, but most did not want advice from colleagues of the same service. Almost all surgeons ask for advice when prescribing, but only 68% of the internists do it. Less than half of all physicians and only 25% of the surgeons felt free to prescribe contrary to guidelines. Most physicians, particularly in Intensive Care Medicine (94%), adopt the "wait and see" strategy when no microbiologic confirmation is available, but 27% of the surgeons start empirical therapy. In conclusion, the context of antimicrobial prescription, autonomy, and confidence in antimicrobial prescription demonstrated heterogeneity between the three departments and this should be considered when planning ASP.

A scoping review and behavioural analysis of factors underlying overuse of antimicrobials

Background

Overuse of antimicrobials is a challenging global issue that contributes to antimicrobial resistance. Despite widespread awareness of the problem among members of the medical community and various attempts to improve prescription practices, existing antimicrobial stewardship programmes are not always effective. In our view, this may reflect limited understanding of factors that influence prescription of antimicrobials as empirical therapy, implying a need to address the psychological mechanisms behind some of the specific behaviours involved.

Objectives

To identify factors that influence the antimicrobials prescription as empirical therapy, and to relate these factors to findings from behavioural science.

Methods

We conducted a scoping review of the literature on the factors underlying antimicrobial prescription decisions, following the protocol designed using PRISMA guidelines.

Results and conclusions

From a final sample of 90 sources, we identified ten factors important in antimicrobial prescription decisions. In the second stage of our analysis, we grouped them into five final categories: (1) nature of the decision, (2) social influences, (3) individual differences, (4) characteristics of the patient, (5) context. We analyse these categories using a behavioural science perspective.

Four years after the implementation of antimicrobial stewardship program in Jordan: evaluation of program's core elements

Objectives

To combat antimicrobial resistance, the World Health Organization (WHO) urged healthcare organizations in Low- and Middle-Income Countries (LMICs) to implement the core elements of the antimicrobial stewardship (AMS) programs. In response, Jordan took action and developed a national antimicrobial resistance action plan (NAP) in 2017 and commenced the AMS program in all healthcare facilities. It is paramount to evaluate the efforts to implement the AMS programs and understand the challenges of implementing a sustainable and effective program, in Low-Middle Income Country (LMIC) contexts. Therefore, the aim of this study was to appraise the compliance of public hospitals in Jordan to the WHO core elements of effective AMS programs after 4 years of commencement.

Methods

A cross-sectional study in public hospitals in Jordan, using the WHO AMS program core elements for LMICs was carried out. The questionnaire comprised 30 questions that covered the program's six core elements: leadership commitment, accountability and responsibility, AMS actions, education and training, monitoring, and evaluation, and reporting and feedback. A five-point Likert scale was employed for each question.

Results

A total of 27 public hospitals participated, with a response rate of 84.4%. Adherence to core elements ranged from (53%) in the leadership commitment domain to (72%) for AMS procedure application (actions). Based on the mean score, there was no significant difference between hospitals according to location, size, and specialty. The most neglected core elements that emerged as top priority areas were the provision of financial support, collaboration, access, as well as monitoring and evaluation.

Conclusion

The current results revealed significant shortcomings in the AMS program in public hospitals despite 4 years of implementation and policy support. Most of the core elements of the AMS program were below average, which requires hospital leadership commitment, and multifaceted collaborative actions from the concerned stakeholders in Jordan.

Perspectives of Statistician, Microbiologist, and Clinician Stakeholders on the Use of Microbiological Outcomes in Randomised Trials of Antimicrobial Stewardship Interventions

Microbiological data are used as indicators of infection, for diagnosis, and the identification of antimicrobial resistance in trials of antimicrobial stewardship interventions. However, several problems have been identified in a recently conducted systematic review (e.g., inconsistency in reporting and oversimplified outcomes), which motivates the need to understand and improve the use of these data including analysis and reporting. We engaged key stakeholders including statisticians, clinicians from both primary and secondary care, and microbiologists. Discussions included issues identified in the systematic review and questions about the value of using microbiological data in clinical trials, perspectives on current microbiological outcomes reported in trials, and alternative statistical approaches to analyse these data. Various factors (such as unclear sample collection process, dichotomising or categorising complex microbiological data, and unclear methods of handling missing data) were identified that contributed to the low quality of the microbiological outcomes and the analysis of these outcomes in trials. Whilst not all of these factors would be easy to overcome, there is room for improvement and a need to encourage researchers to understand the impact of misusing these data. This paper discusses the experience and challenges of using microbiological outcomes in clinical trials.

Behavior-change interventions to improve antimicrobial stewardship in human health, animal health, and livestock agriculture: A systematic review

Antimicrobial resistance (AMR) is an economic, food security, and global health threat accelerated by a multitude of factors including the overuse and misuse of antimicrobials in the human health, animal health, and agriculture sectors. Given the rapid emergence and spread of AMR and the relative lack of development of new antimicrobials or alternative therapies, there is a need to develop and implement non-pharmaceutical AMR mitigation policies and interventions that improve antimicrobial stewardship (AMS) practices across all sectors where antimicrobials are used. We conducted a systematic literature review per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify peer-reviewed studies that described behavior-change interventions that aimed to improve AMS and/or reduce inappropriate antimicrobial use (AMU) among human health, animal health, and livestock agriculture stakeholders. We identified 301 total publications- 11 in the animal health sector and 290 in the human health sector-and assessed described interventions using metrics across five thematic areas- (1) AMU, (2) adherence to clinical guidelines, (3) AMS, (4) AMR, and (5) clinical outcomes. The lack of studies describing the animal health sector precluded a meta-analysis. Variation across intervention type, study type, and outcome precluded a meta-analysis for studies describing the human health sector; however, a summary descriptive analysis was conducted. Among studies in the human health sector, 35.7% reported significant (p<0.05) pre- to post-intervention decreases in AMU, 73.7% reported significant improvements in adherence of antimicrobial therapies to clinical guidelines, 45% demonstrated significant improvements in AMS practices, 45.5% reported significant decreases in the proportion of isolates that were resistant to antibiotics or the proportion of patients with drug-resistant infections across 17 antimicrobial-organism combinations. Few studies reported significant changes in clinical outcomes. We did not identify any overarching intervention type nor characteristics associated with successful improvement in AMS, AMR, AMU, adherence, nor clinical outcomes.

Awareness and Knowledge of Antimicrobial Resistance, Antimicrobial Stewardship and Barriers to Implementing Antimicrobial Susceptibility Testing among Medical Laboratory Scientists in Nigeria: A Cross-Sectional Study

Background: Antimicrobial resistance (AMR) is now considered one of the greatest global health threats. This is further compounded by a lack of new antibiotics in development. Antimicrobial stewardship programmes can improve and optimize the use of antibiotics, thereby increasing the cure rates of antibiotic treatment and decreasing the problem of AMR. In addition, diagnostic and antimicrobial stewardships in the pathology laboratories are useful tools to guide clinicians on patient treatment and to stop the inappropriate use of antibiotics in empirical treatment or narrow antibiotics. Medical Laboratory Scientists are at the forefront of performing antibiotics susceptibility testing in pathology laboratories, thereby helping clinicians to select the appropriate antibiotics for patients suffering from bacterial infections. Methods: This cross-sectional study surveyed personal antimicrobial usage, the knowledge and awareness on AMR, and antimicrobial stewardship, as well as barriers to antimicrobial susceptibility testing among medical laboratory scientists in Nigeria using pre-tested and validated questionnaires administered online. The raw data were summarized and exported in Microsoft Excel and further analyzed using IBM SPSS version 26. Results: Most of the respondents were males (72%) and 25-35 years old (60%). In addition, the BMLS degree was the highest education qualification most of the respondents (70%) achieved. Of the 59.2% of the respondents involved in antibiotics susceptibility testing, the disc diffusion method was the most commonly used (67.2%), followed by PCR/Genome-based detection (5.2%). Only a small percentage of respondents used the E-test (3.4%). The high cost of testing, inadequate laboratory infrastructure, and a lack of skilled personnel are the major barriers to performing antibiotics susceptibility testing. A higher proportion of a good AMR knowledge level was observed in male respondents (75%) than females (42.9%). The knowledge level was associated with the respondent's gender (p = 0.048), while respondents with a master's degree were more likely to possess a good knowledge level of AMR (OR: 1.69; 95% CI: 0.33, 8.61). Conclusion: The findings of this study indicate that Nigerian medical laboratory scientists had moderate awareness of AMR and antibiotic stewardship. It is necessary to increase investments in laboratory infrastructure and manpower training, as well as set up an antimicrobial stewardship programme to ensure widespread antibiotics susceptibility testing in hospitals, thereby decreasing empirical treatment and the misuse of antibiotics.

Patient expectations do matter - Experimental evidence on antibiotic prescribing decisions among hospital-based physicians

BACKGROUND

The global public health crisis of antibiotic resistance is being driven in part by over prescription of antibiotics. We aimed to assess the relative weight of patient expectations, clinical uncertainty, and past behaviour on hospital-based physicians' antibiotic prescribing decisions.

METHODS

A discrete choice experiment was administered among hospital-based physicians in Tuscany, Italy. Respondents were asked to choose in which of two clinical scenarios they would be more likely to prescribe antibiotics, with the two cases differing in levels of clinical uncertainty, patient expectations, and the physician's past behaviour. We fitted a conditional logistic regression.

RESULTS

Respondents included 1,436 hospital-based physicians. Results show that the odds of prescribing antibiotics decrease when a patient requests it (OR=0.80, 95%CI [0.72,0.89]) and increase when the physician has prescribed antibiotics to a patient under similar circumstances previously (OR=1.15, 95%CI [1.03,1.27]). We found no significant effect of clinical uncertainty on the odds of prescribing antibiotics (OR=0.96, 95%CI [0.87, 1.07]).

CONCLUSIONS

We show that patient expectation has a significant negative association with antibiotic prescribing among hospital-based physicians. Our findings speak to the importance of cultural context in shaping the physician's disposition when confronted with patient expectations. We suggest shared decision-making to improve prudent prescribing without compromising on patient satisfaction.

Increase in the Rate of Gut Carriage of Fluoroquinolone-Resistant Escherichia coli despite a Reduction in Antibiotic Prescriptions

Background : Fluoroquinolone use for urinary tract infections has been steadily declining. Gut microbiota is the main reservoir for uropathogenic Escherichia coli but whether the carriage of fluoroquinolone-resistant E. coli has been changing is unknown. Methods . We determined the frequency of isolation and other characteristics of E. coli nonsuceptible to fluoroquinolones (at ³0.5 mg/L of ciprofloxacin) in 515 and 1605 E. coli -positive fecal samples collected in 2015 and 2021, respectively, from non-antibiotic- taking women of age 50+ receiving care in the Seattle area Kaiser Permanente Washington healthcare system. Results . Between 2015 and 2021 the prescription of fluoroquinolones dropped nearly three-fold in the study population. During the same period, the rates of gut carriage of fluoroquinolone-resistant E. coli increased from 14.4 % to 19.9% (P=.005), driven by a significant increase of isolates from the recently emerged, pandemic multi-drug resistant clonal group ST1193 (1.7% to 4.3%; P=.007) and those with an incomplete set of or no fluoroquinolone-resistance determining mutations (2.3% to 7.5%; P<.001). While prevalence of the resistance-associated mobile genes among the isolates dropped from 64.1% to 32.6% (P<.001), co-resistance to third generation cephalosporins has increased 21.5% to 33.1%, P=.044). Conclusion . Despite reduction in fluoroquinolone prescriptions, gut carriage of fluoroquinolone-resistant uropathogenic E. coli increased with a rise of previously sporadic lineages and co-resistance to third generation cephalosporins. Thus, to reduce the rates of antibiotic resistant urinary tract infections, greater focus should be on controlling the gut carriage of resistant bacteria.

Trimethoprim-sulfamethoxazole induced aseptic meningitis case report

RATIONALE

Drug-induced aseptic meningitis (DIAM) is an uncommon meningitis and trimethoprim with or without sulfamethoxazole is the most involved antibiotic. Although DIAM is easily treated with the discontinuation of the causative drug, the diagnosis is a big challenge for physicians, as it remains a diagnosis of exclusion. Here, we present a case report of trimethoprim-sulfamethoxazole induced aseptic meningitis in a woman with acute osteomyelitis.

PATIENT CONCERNS

A 52-year-old woman was admitted to the hospital for septic shock and acute osteomyelitis of the right homerus. She was started on antibiotic therapy with oxacillin and daptomycin, then oxacillin was replaced with cotrimoxazole, due to its excellent tissue penetration, including bone tissue. During cotrimoxazole therapy, the patient developed a fluent aphasia with ideomotor apraxia and muscle hypertonus.

DIAGNOSIS AND INTERVENTIONS

Having excluded infectious, epileptic and vascular causes of the acute neurologic syndrome of our patient, given the improvement and full recovery after discontinuation of cotrimoxazole, we hypothesized a DIAM.

OUTCOMES

After discontinuation of cotrimoxazole, in 48 hours the patient had a full recovery.

LESSONS

Although DIAM can be easily managed with the withdrawal of the causative drug, it can be difficult to recognize if it is not included in the differential diagnosis. An antimicrobial stewardship program with a strict monitoring of patients by infectious disease specialists is essential, not only to optimize the appropriate use of antimicrobials, but also to improve patient outcomes and reduce the likelihood of adverse events.

Health care systems administrators perspectives on antimicrobial stewardship and infection prevention and control programs across three healthcare levels: a qualitative study

INTRODUCTION

Antimicrobial stewardship (AMS) and infection prevention control (IPC) programs are proposed to address antimicrobial resistance. Nigeria's 5-years action plan for these programs is expiring by 2022. The objective of this study was to examine the perspectives, barriers and facilitators of these programs among health care managers and the current state of these programs in the three levels of healthcare facilities in Benin City, Nigeria.

METHODS

Fourteen in-depth interviews were conducted among hospital manager across primary, secondary and tertiary healthcare facilities. The interviews were guided by semi-structured questionnaire. Responses were audio-taped and hand written. Data were analyzed by transcribing recorded tapes into major themes.

RESULTS

Most of the participants viewed inappropriate prescribing as a problem both in the country and their facilities. None of the institutions have a formal AMS program, but participants believed that the presence of drug and therapeutic committee is a foundation for such programme. Majority of the participants acknowledged barriers to AMS to include lack of management backing, interprofessional rivalry, and poor laboratories. Only the tertiary institution has a formal IPC program. Some challenges to IPC across the healthcare institutions are inadequate waste disposal, lack of personal protective equipment and behavioral change among healthcare providers.

CONCLUSION

There is no AMS program across all facilities studied, although some forms of IPC activities are present in all healthcare institutions, only the tertiary facility has a formal IPC program. Effort should be made to strengthen AMS and IPC in the study facilities.

Impact of antimicrobial stewardship on antibiogram, consumption and incidence of multi drug resistance

INTRODUCTION

Antimicrobial stewardship programs are intended to improve patient outcomes, reduce side effects, bacterial resistance, and costs. Thus, it is important to assess their impact on an ongoing basis. We aimed to assess the impact of the antimicrobial stewardship program in two different hospitals which used different program approaches.

METHODOLOGY

This is a retrospective observational study in two private hospitals [4088 patient records] in Amman- Jordan. Antibiotic susceptibility using antibiogram results, consumption of antibiotics using Defined Daily Dose, and the incidence of Multi-Drug Resistance were recorded using patients' records during 2018, 2019, and 2020.

RESULTS

Antimicrobial stewardship program outcomes varied between the two hospitals. Bacterial susceptibility to antibiotics were improved in both hospitals. Moreover, the defined daily dose in Hospital "A" showed no significant change in Fluoroquinolones, Carbapenems, and Piperacillin- Tazobactam, Cephalosporins, and Colistin, while a significant change was observed among Anti-MRSA antibiotics. Finally, the incidence of Extended Spectrum Beta-lactamase [ESBL] E. coli, ESBL Klebsiella, and Vancomycin Resistant Enterococci [VRE] have decreased numerically over the study period, while Methicillin-Resistant Staphylococcus aureus [MRSA] showed an increase in incidence during the second year of the study.

CONCLUSION

The study emphasizes the positive impact of the AMS program throughout the three years of the study. Plus, the need to enhance the program through recruiting extra staff and applying extra regulations like implementing educational programs for the hospital staff, designing local guidelines for common ID diseases, and monitoring the program's outcomes which would eventually be more efficient, cost-effective, and safe.

Assessing antibiotic prescribing in nurse practitioners: Applied cognitive task analysis

Background

Prescribing antibiotics is a demanding and complex task where decision-making skills are of critical importance to minimize the risk of antimicrobial resistance. Despite its importance, little is known about the decision-making skills and cognitive strategies new Nurse Practitioners (NPs) use when prescribing antibiotics.

Objective

To identify the cognitive demands of antibiotic prescribing complexity and to explore the cognitive strategies that new NPs in New Zealand use when prescribing antibiotics.

Design

A qualitative approach using Applied Cognitive Task Analysis (ACTA) methodology.

Participants

A purposive sample was recruited consisting of five NPs who had been registered within the last five years and were prescribing antibiotics as part of their scope of practice.

Methods

In-depth face-to-face interviews consisting of a task diagram interview and a knowledge audit were conducted and analyzed following the ACTA protocol.

Results

Four cognitive elements were identified from the data which showed the cognitive demands of prescribing antibiotics, and the cues and strategies NPs use for safe practice. These were: 1 prescribing in the face of uncertainty (complex patients and diagnostic uncertainty); 2 making clinical decisions with insufficient/poor guidance (lack of guidelines, conflicting information); 3 producing an individualized treatment plan in view of clinical and non-clinical patient factors (patient demand/expectation, inadequate patient education, risks versus benefits of antibiotic treatment); 4 ensuring treatment efficacy and continuity of care (ineffective treatment, patient care follow up).

Conclusion

The ACTA framework has given insight into the current antibiotic prescribing practice of new NPs, identifying areas where professional development courses and treatment resources can be targeted to support antibiotic prescribing. NPs are likely to benefit from resources that are freely available and reflect national or local antimicrobial data. Further work is also warranted to determine whether targeted education resources and clinical pathways will help with diagnostic uncertainty, and how this could be embedded into existing curricula.

The impact of pharmacists' interventions within the Closed Loop Medication Management process on medication safety: An analysis in a German university hospital

Background: Single elements of the Closed Loop Medication Management process (CLMM), including electronic prescribing, involvement of clinical pharmacists (CPs), patient individual logistics and digital administration/documentation, have shown to improve medication safety and patient health outcomes. The impact of the complete CLMM on patient safety, as reflected in pharmacists' interventions (PIs), is largely unknown. Aim: To evaluate the extent and characterization of routine PIs performed by hospital-wide CPs at a university hospital with an implemented CLMM. Methods: This single-center study included all interventions documented by CPs on five self-chosen working days within 1 month using the validated online-database DokuPIK (Documentation of Pharmacists' Interventions in the Hospital). Based on different workflows, two groups of CPs were compared. One group operated as a part of the CLMM, the "Closed Loop Clinical Pharmacists" (CL-CPs), while the other group worked less dependent of the CLMM, the "Process Detached Clinical Pharmacists" (PD-CPs). The professional experience and the number of medication reviews were entered in an online survey. Combined pseudonymized datasets were analyzed descriptively after anonymization. Results: A total of 1,329 PIs were documented by nine CPs. Overall CPs intervened in every fifth medication review. The acceptance rate of PIs was 91.9%. The most common reasons were the categories "drugs" (e.g., indication, choice of formulation/drug and documentation/transcription) with 42.7%, followed by "dose" with 29.6%. One-quarter of PIs referred to the therapeutic subgroup "J01 antibacterials for systemic use." Of the 1,329 underlying PIs, 1,295 were classified as medication errors (MEs) and their vast majority (81.5%) was rated as "error, no harm" (NCC MERP categories B-D). Among PIs performed by CL-CPs (n = 1,125), the highest proportion of errors was categorized as B (56.5%), while in the group of PIs from PD-CPs (n = 170) errors categorized as C (68.2%) dominated (p < 0.001). Conclusion: Our study shows that a structured CLMM enables CPs to perform a high number of medication reviews while detecting and solving MEs at an early stage before they can cause harm to the patient. Based on key quality indicators for medication safety, the complete CLMM provides a suitable framework for the efficient medication management of inpatients.

Nurses' Perceptions, Involvement, Confidence and Perceived Barriers Towards Antimicrobial Stewardship Program in Pakistan: Findings from a Multi-Center, Cross-Sectional Study

Purpose

Antimicrobial resistance (AMR) is leading to greater therapeutic cost, length of hospital stays, adverse events, morbidity and mortality. Hospital-based antimicrobial stewardship programs (ASPs) engaging physicians, pharmacists, microbiologists and nurses are considered as effective way to ensure appropriate use of antimicrobial agents. The aims of our study were to assess nurses' perception, involvement, confidence and barriers towards hospital-based ASPs, and use the findings to provide future guidance.

Methods

A web-based, cross-sectional study was conducted among the nurses serving at eleven hospitals of Punjab province of Pakistan during a period of two months (December 2021-January 2022). Data were collected using a validated self-administered questionnaire. All data were analyzed using SPSS version 22.

Results

A total of 583 nurses participated in the study (response rate = 77.7%). All the participants were female staff nurses and 86% had a minimum of 3 years of working experience. The overall median score on the perception towards ASPs among the nurses was 18 (IQR: 16, 19) on a 0 to 20 scale whereas median score on the involvement in ASPs was 18 (IQR: 15, 37) on a 0 to 64 scale. Median perception and involvement score were statistically significantly differed by age (p < 0.001) and years of experience (p < 0.001). The overall median score on the confidence to perform ASP activities was 22 (IQR: 14, 24) on a 0 to 28 scale. Lack of knowledge, insufficient support from administration, and heavy workload were found to be the common barriers to perform ASP.

Conclusion

Our study concluded that Pakistani nurses have positive perception but limited involvement in ASPs. Moreover, they are confident to perform ASP besides many barriers.
