A systematic review of Antimicrobial Stewardship Program implementation in Middle Eastern countries

Antimicrobial resistance: Linking molecular mechanisms to public health impact

BACKGROUND

Antimicrobial resistance (AMR) develops into a worldwide health emergency through genetic and biochemical adaptations which enable microorganisms to resist antimicrobial treatment. β-lactamases (blaNDM, blaKPC) and efflux pumps (MexAB-OprM) working with mobile genetic elements facilitate fast proliferation of multidrug-resistant (MDR) and exttreme drug-resistant (XDR) phenotypes thus creating major concerns for healthcare systems and community health as well as the agricultural sector.

OBJECTIVES

The review dissimilarly unifies molecular resistance pathways with public health implications through the study of epidemiological data and monitoring approaches and innovative therapeutic solutions. Previous studies separating their attention between molecular genetics and clinical outcomes have been combined into our approach which delivers an all-encompassing analysis of AMR.

KEY INSIGHTS

The report investigates the resistance mechanisms which feature enzymatic degradation and efflux pump overexpression together with target modification and horizontal gene transfer because these factors represent important contributors to present-day AMR developments. This review investigates AMR effects on hospital and community environments where it affects pathogens including MRSA, carbapenem-resistant Klebsiella pneumoniae, and drug-resistant Pseudomonas aeruginosa. This document explores modern AMR management methods that comprise WHO GLASS molecular surveillance systems and three innovative strategies such as CRISPR-modified genome editing and bacteriophage treatments along with antimicrobial peptides and artificial intelligence diagnostic tools.

CONCLUSION

The resolution of AMR needs complete scientific and global operational methods alongside state-of-the-art therapeutic approaches. Worldwide management of drug-resistant infection burden requires both enhanced infection prevention procedures with next-generation antimicrobial strategies to reduce cases effectively.

Impact of an antimicrobial time-out program on antimicrobial consumption rate in hospitalized patients: a quasi-experimental study on the national antimicrobial stewardship program in Iran : Iranian antimicrobial stewardship program

BACKGROUND

This study evaluated the impact of the national antimicrobial stewardship program (NASP) on the consumption of antimicrobial agents.

METHODS

A quasi-experimental study was conducted on hospitalized patients at a referral hospital in Tehran, Iran. We compared the antimicrobial-defined daily dose (DDD) and antimicrobial consumption index (ACI) between the third quarter of 2022 (before the implementation of NASP after the COVID-19 pandemic in October 2022) and the same timeframe in 2023, following the NASP implementation. The NASP was based on antimicrobial time-out assessment. Within 72 h of prescribing meropenem, imipenem, linezolid, vancomycin, voriconazole, caspofungin, and amphotericin B liposomal, infectious disease specialists audited the clinical and microbiological evidence of patients to assess whether it was consistent with the correct prescription.

RESULTS

The antimicrobial consumption rate was assessed in 13,794 and 15,030 hospitalized patients during the third quarter of 2022 and the third quarter of 2023, respectively. The mean length of hospital stay and mortality rate showed no significant differences. The consumption of all restricted antimicrobials decreased. This reduction was significant for imipenem, caspofungin, vancomycin, and linezolid. The total cost of antimicrobial agents had a 22.24% reduction after the NASP implementation (P = 0.01).

CONCLUSIONS

The antimicrobial time-out program was associated with a reduction in the use of antimicrobials, including imipenem, linezolid, and vancomycin and antifungals, such as caspofungin without increasing the length of stay and mortality rate. The NASP implementation can be recommended as a beneficial method for reducing the use of broad-spectrum antimicrobials.

The ongoing antibiotic resistance and carbapenemase encoding genotypes surveillance. The first quarter report of the INVIFAR network for 2024

INTRODUCTION

Antimicrobial resistance surveillance plays an important role in generating information about the prevalence of resistant microorganisms. In this study, we summarize a surveillance of antimicrobial resistance and carbapenemase-encoding genes for selected pathogens in Mexican healthcare centers.

METHODS

Databases of identification and susceptibility results collected from January 1 to March 31, 2024, from forty-one centers were gathered and analyzed using the WHONET software. Some relevant gram-negatives and gram-positives, which were isolated from relevant clinical specimens were included. Isolates were stratified by patient´s age, clinical specimens, and site of attention, and were classified as multidrug-resistant (MDR). Clinical isolates were collected from January 1 to June 30 and were genotyped for carbapenemase-encoding genes by a polymerase chain reaction test.

RESULTS

In total, 8 708 strains were included. Escherichia coli had a higher resistance to carbapenems (p < 0.05) in the 0-17 years group and Klebsiella pneumoniae (p = 0.017), Pseudomonas aeruginosa, and Acinetobacter baumannii (p < 0.05) in the 18-59 years group. P. aeruginosa had higher resistance to ceftazidime-avibactam, ceftolozane-tazobactam, cefepime, and imipenem (p < 0.05) in the 18-59 years group. K. pneumoniae had the highest resistance to carbapenems (p < 0.05) and cefepime (p < 0.001) in clinical isolates recovered from blood. For P. aeruginosa, the highest resistance to cefepime (p = 0.012) and ceftazidime (p < 0.018) was seen in isolates from urine. For Staphylococcus aureus, a higher resistance was observed for cefoxitin in lower respiratory tract specimens (p < 0.05). E. coli had the highest resistance to carbapenems (p < 0.01), and P. aeruginosa for ceftazidime (p = 0.005), cefepime (p = 0.003), piperacillin-tazobactam (p = <0.01), IPM (p = 0.006), and meropenem (p = <0.01) in clinical isolates recovered from patients in the intensive care unit (ICU). For K. pneumoniae, the highest resistance to ertapenem was observed in clinical isolates from the ICU area (p < 0.035). Finally, 67.9% of A. baumannii and 53.8% of E. coli strains were Multidrug-resistant. Candida albicans isolated from blood had susceptibility to caspofungin 100% and 90.2% for voriconazole. Regarding E. coli non-susceptible to meropenem, 16 (59.2%) were carriers of blaNDM, and the blaKPC gene was detected in 2 (40%) strains of K. pneumoniae. In conclusion, carbapenem resistance was higher for E. coli in the 0-17 years group and for K. pneumoniae, P. aeruginosa, and A. baumannii in the 18-59 years group. K. pneumoniae has the highest resistance to carbapenems in blood isolates and the ICU area. E. coli and P. aeruginosa had the highest carbapenem resistance in the intensive care unit. A high multidrug resistance was observed for A. baumannii and E. coli strains. A high susceptibility to caspofungin and voriconazole was observed for Candida albicans collected from blood.

Detection of antimicrobial resistance via state-of-the-art technologies versus conventional methods

Antimicrobial resistance (AMR) is recognized as one of the foremost global health challenges, complicating the treatment of infectious diseases and contributing to increased morbidity and mortality rates. Traditionally, microbiological culture and susceptibility testing methods, such as disk diffusion and minimum inhibitory concentration (MIC) assays, have been employed to identify AMR bacteria. However, these conventional techniques are often labor intensive and time consuming and lack the requisite sensitivity for the early detection of resistance. Recent advancements in molecular and genomic technologies-such as next-generation sequencing (NGS), matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), lateral flow immunoassays (LFIAs), PCR-based diagnostic methods, and CRISPR-based diagnostics-have revolutionized the diagnosis of AMR. These innovative approaches provide increased sensitivity, reduced turnaround times, and the ability to identify genetic resistance mechanisms. This review seeks to examine the advantages and disadvantages of both emerging technologies and traditional methods for detecting AMR, emphasizing the potential benefits and limitations inherent to each. By understanding the strengths and limitations of these technologies, stakeholders, including researchers, healthcare professionals, regulatory agencies, health authorities, financial managers, and patients, can make informed decisions aimed at preventing the emergence and dissemination of antibiotic-resistant strains, thereby ultimately increasing patient safety.

Implementation of Antimicrobial Stewardship Programs in Saudi Arabia: A Systematic Review

BACKGROUND

Antimicrobial resistance has highlighted the need for effective infectious disease strategies. Antimicrobial stewardship programs (ASPs) may reduce antibiotic resistance, adverse reactions, and treatment failures. This systematic review examines ASPs in Saudi Arabia, assessing their efficacy, challenges, and outcomes to improve antimicrobial use and patient care.

METHODS

Searches were carried out in the Ovid, MEDLINE, Embase, PsycInfo, Scopus, and Web of Science Core Collection databases for studies published from 2007 to July 2024, in Saudi Arabia, following the PRISMA guidelines. Studies that assessed ASPs' implementation, effectiveness, and outcomes in hospital settings were included.

RESULTS

Out of the 6080 titles identified, 14 studies met the inclusion criteria, covering different regions of the country, including Riyadh, Jeddah, Dhahran, Makkah, Al-Kharj, and a multi-regional study in Qassim and Riyadh. Various interventions were implemented by the ASPs, such as educational programs, audit and feedback, switching from intravenous to oral administration, and enhanced policies. These interventions collectively led to a decrease in the overall antimicrobial consumption and cost, and a reduction in cases with multidrug-resistant bacteria.

CONCLUSIONS

The findings of this review highlight the positive impact of ASPs in Saudi Arabia. However, addressing challenges such as data limitations and training gaps is essential to enhance their effectiveness. Expanding education and refining implementation strategies are crucial for ensuring their long-term success.

Epidemiology of urinary tract infections in the Middle East and North Africa, 1990-2021

OBJECTIVE

This research reports the incidence, mortality, and disability-adjusted life years (DALYs) associated with urinary tract infections (UTIs) in the Middle East and North Africa (MENA) region, stratified by sex, age, and Socio-demographic Index (SDI) from 1990 to 2021.

METHODS

Data were sourced from the Global Burden of Disease 2021 study, encompassing all 21 countries in the region. Metrics such as absolute counts, age-standardised rates, and percentage changes from 1990 to 2021 are presented with 95% uncertainty intervals (UIs).

RESULTS

In 2019, the MENA region recorded an incidence rate of 4,033.4 per 100,000 (95% UIs: 3,553.7-4,548.7) and 7,687 deaths (95% UIs: 6,663-8,969). The DALY rate was 41.3 per 100,000 (95% UIs: 36.1-47.2), which was highest among older adults, reaching a peak in the 80-89 age range, and increasing with age, particularly from the 50 + age groups. A non-linear relationship was identified between the burden of UTIs and the SDI, with higher-than-expected rates in lower SDI countries such as Syria and Lebanon.

CONCLUSION

Despite a substantial increase in the total number of UTI cases and DALYs in the region from 1990 to 2021, the age-standardised rates remained stable. The larger burden in lower SDI countries highlights the urgent need for targeted public health interventions. Improving healthcare access and antibiotic stewardship is crucial to mitigating the growing burden of UTIs, particularly among older populations in the region.

Evaluation of antimicrobial selective pressure using the multicenter semiautomatic surveillance system Japan surveillance for infection prevention and healthcare epidemiology

BACKGROUND

Evaluating the selective pressure of antimicrobials on bacteria is important for promoting antimicrobial stewardship programs (ASPs). The aim of this study was to assess the selective pressure of antimicrobials by evaluating their use (carbapenem [CBP] and CBP-sparing therapy) over time and the detection status of CBP-resistant organisms using multicenter data.

METHODS

Among the facilities whose data were registered in the Japan Surveillance for Infection Prevention and Healthcare Epidemiology from 2017 to 2020, those that had data on the use of CBP and CBP-sparing therapy (fluoroquinolones [FQs], cefmetazole [CMZ], piperacillin-tazobactam [PIP/TAZ], ampicillin-sulbactam [ABPC/SBT], ceftriaxone/cefotaxime [CTRX/CTX], CAZ (ceftazidime), cefepime [CFPM], and aminoglycosides [AGs]) as well as on CBP-resistant Enterobacterales (CRE) and CBP-resistant Pseudomonas aeruginosa (CRPA) detection were included. Alcohol-based hand rubbing (ABHR) usage was also analyzed. Regression analyses, including multivariable regression analysis, were performed to evaluate trends. The association of antimicrobial use density (AUD) with CRE and CRPA detection rates was evaluated.

RESULTS

In 28 facilities nationwide, CBP, FQ, CAZ, AG, and PIP/TAZ use decreased over the 3-year period, whereas the use of CMZ, ABPC/SBT, CTRX/CTX, CFPM, and ABHR as well as the rates of CRE and CRPA detection increased. The average AUD did not significantly correlate with CRE and CRPA detection rates. The multivariable regression analysis did not reveal any significant correlation between each AUD or ABHR and CRE or CRPA detection.

CONCLUSION

CBP and ABHR use showed a decreasing and an increasing trend, respectively, while CRPA and CRE detection rates exhibited a gradual increase. The considerably low CRE and CRPA detection rates suggest that slight differences in numbers may have been observed as excessive trend changes. Further investigation is warranted to evaluate selective pressure while considering the characteristics of ASP and the mechanisms underlying resistance.

Stewardship: it's going viral

Introduction

Historically, antimicrobial stewardship (AMS) has considered the judicious use of antibiotics. AMS is widely adopted across Europe and the US; recently antifungal AMS is gaining momentum but antiviral AMS has been little described. Here we describe the introduction of AMS virology reviews at University Hospitals Birmingham (UHBFT); a novel concept and an opportunity to broaden the beneficial aspects of AMS to virology, termed anti-viral stewardship (AVS).

Method

In June 2022, a UK supply issue with aciclovir injection (ACV IV) was announced. In order to review and preserve parenteral ACV for those in greatest need, UHBFT pharmacist and virologists implemented a specialist review for patients prescribed more than 48 hours of treatment. This review initially lasted 10 weeks and data was collected on the advice offered, whether it was accepted, and time required completing the review.

Results

AVS rounds halved IV ACV consumption, compared to pre or post intervention levels, with more than half of patients advised to stop or switch to oral therapy. Diagnostics and sampling guidance was offered in one quarter of reviews, whilst the remaining interventions were more stewardship focused. In almost all cases stewardship advice was readily accepted by clinical teams. Due to positive feedback from clinicians and its effective management of supply, the anti-viral stewardship (AVS) programme was re-introduced in June 2023.

Conclusions

Antiviral AMS rounds provide an opportunity to optimise sampling, diagnosis and improve patient management. Introduction of regular AVS at UHBFT are now well established and plan to be implemented in other hospitals.

Antimicrobial Resistance: Stewardship and One Health in the Eastern Mediterranean Region

Antimicrobial resistance (AMR) is a major threat in the Eastern Mediterranean region (EMR) due to factors such as the high prevalence of infectious diseases, weak health systems, and the misuse of antimicrobials. This paper aims to discuss how interdisciplinary action and collaboration, specifically through antimicrobial stewardship (AMS) and the One Health approach, can effectively address AMR in the EMR. The review focuses on successful AMS initiatives and the adoption of the One Health approach in countries within the EMR, including the Gulf Cooperation Countries (GCC), Egypt, Iran, Jordan, and Pakistan. The goal is to highlight the potential for progress in combating AMR and identify challenges and opportunities for strengthening interdisciplinary collaboration. The results showcase successful AMS programs and One Health initiatives in various EMR countries, demonstrating their potential to address AMR challenges. The paper also discusses the challenges faced by these nations, such as limited resources, fragmented health systems, and knowledge gaps. Additionally, opportunities for enhancing interdisciplinary action through regional cooperation, international partnerships, and research and innovation are outlined. In conclusion, this paper emphasizes the importance of a comprehensive and collaborative response to combat AMR in the EMR. It advocates for the One Health approach as a crucial framework to guide these efforts, promoting coordinated action, improved surveillance, responsible antimicrobial use, and enhanced interdisciplinary collaboration to effectively mitigate the threat of AMR.

Exploring determinants of antimicrobial prescribing behaviour using the Theoretical Domains Framework

BACKGROUND

Few theoretically-based, qualitative studies have explored determinants of antimicrobial prescribing behaviour in hospitals. Understanding these can promote successful development and implementation of behaviour change interventions (BCIs).

OBJECTIVE

(s): To use the Theoretical Domains Framework (TDF) to explore determinants of clinicians' antimicrobial prescribing behaviour, identifying barriers (i.e., impediments) and facilitators to appropriate antimicrobial practice.

METHODS

Semi-structured interviews with purposively-sampled doctors and pharmacists with a wide range of specialties and expertise in Hamad Medical Corporation hospitals in Qatar. Interviews based on previous quantitative research and the TDF were audio-recorded, transcribed and independently analysed by two researchers using the TDF as an initial coding framework.

RESULTS

Data saturation was achieved after interviewing eight doctors and eight pharmacists. Inter-related determinants of antimicrobial prescribing behaviour linked to ten TDF domains were identified as barriers and facilitators that may contribute to inappropriate or appropriate antimicrobial prescribing. The main barriers identified were around hospital guidelines and electronic system deficiencies (environmental context and resources); knowledge gaps relating to guidelines and appropriate prescribing (knowledge); restricted roles/responsibilities of microbiologists and pharmacists (professional role and identity); challenging antimicrobial prescribing decisions (memory, attention and decision processes); and professional hierarchies and poor multidisciplinary teamworking (social influences). Key facilitators included guidelines compliance (goals and intentions), and participants' beliefs about the consequences of appropriate or inappropriate prescribing. Further education and training, and some changes to guidelines including their accessibility were also considered essential.

CONCLUSIONS

Antimicrobial prescribing behaviour in hospitals is a complex process influenced by a broad range of determinants including specific barriers and facilitators. The in-depth understanding of this complexity provided by this work may support the development of an effective BCI to promote appropriate antimicrobial stewardship.

Evaluation of Hospital Antimicrobial Stewardship Programs: Implementation, Process, Impact, and Outcomes, Review of Systematic Reviews

Antimicrobial Stewardship Programs (ASP) were introduced in healthcare as a public health priority to promote appropriate prescribing of antimicrobials, to reduce adverse events related to antimicrobials, as well as to control the escalating challenges of antimicrobial resistance. To deliver aimed outcome objectives, ASPs involve multiple connected implementation process measures. A systematic review was conducted to evaluate both concepts of ASPs. Guided by PRISMA frames, published systematic reviews (SR) focusing on ASPs restricted to secondary and tertiary healthcare were evaluated over the past 10 years involving all age groups. Out of 265 identified SR studies, 63 met the inclusion criteria. The majority were conducted in Europe and North America, with limited studies from other regions. In the reviewed studies, all age groups were examined, although they were conducted mainly on adults when compared to children and infants. Both process and outcomes measures of ASPs were examined equally and simultaneously through 25 different concepts, dominated by efficacy, antimicrobial resistance, and economic impact, while information technology as well as role of pharmacy and behavioral factors were equally examined. The main broad conclusions from the review were that, across the globe, ASPs demonstrated effectiveness, proved efficacy, and confirmed efficiency, while focused evaluation advocated that developed countries should target medium- and small-sized hospitals while developing countries should continue rolling ASPs across healthcare facilities. Additionally, the future of ASPs should focus on embracing evolving information technology to bridge the gaps in knowledge, skills, and attitude, as well as to enhance appropriate decision making.

The Impact of Antifungal Stewardship on Clinical and Performance Measures: A Global Systematic Review

BACKGROUND

Antimicrobial stewardship programs (ASP) have been proposed as an opportunity to optimize antifungal use. The antifungal resistance is a significant and emerging threat. The literature on antifungal stewardship (AFS) and its influence on performance and clinical outcome measures is scarce. This study aimed to examine global evidence of the impact of AFS on patients and performance measures.

METHODS

The "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" (PRISMA) was used for the flow of identification, screening, eligibility, and inclusion. PubMed and MEDLINE were searched using the term ''antifungal stewardship'' on 15 February 2023. Search terms included antifungal stewardship, antimicrobial stewardship, candida, candidemia, candiduria, and invasive fungal disease. Of the 1366 records, 1304 were removed since they did not describe an antifungal stewardship intervention. Among the 62 full texts assessed, 21 articles were excluded since they were non-interventional studies and did not include the outcome of interest. Thus, 41 articles were eligible for systematic review. Eligible studies were those that described an AFS program and evaluated clinical or performance measures.

RESULTS

Of the 41 included studies, the primary performance measure collected was antifungal consumption (22 of 41), and mortality (22 of 41), followed by length of stay (11 of 41) and cost (9 of 41). Most studies were single-center, quasi-experimental, with varying interventions across studies. The principal finding from most of the studies in this systematic review is a reduction in mortality expressed in different units and the use of antifungal agents (13 studies out of 22 reporting mortality). Antifungal consumption was significantly blunted or reduced following stewardship initiation (10 of 22). Comparing studies was impossible due to a lack of standard units, making conducting a meta-analysis unfeasible, which would be a limitation of our study.

CONCLUSION

It has been shown that AFS interventions may improve antifungal consumption and other performance measures. According to available published studies, antifungal consumption and mortality appear to be the possible performance measures to evaluate the impact of AFS.

A Narrative Review of Antibiotic Prescribing Practices in Primary Care Settings in South Africa and Potential Ways Forward to Reduce Antimicrobial Resistance

There are concerns with the current prescribing of antibiotics in both the private and public primary care settings in South Africa. These concerns need to be addressed going forward to reduce rising antimicrobial resistance (AMR) rates in South Africa. Concerns include adherence to current prescribing guidelines. Consequently, there is a need to comprehensively summarise current antibiotic utilization patterns from published studies as well as potential activities to improve prescribing, including indicators and antimicrobial stewardship programs (ASPs). Published studies showed that there was an appreciable prescribing of antibiotics for patients with acute respiratory infections, i.e., 52.9% to 78% or more across the sectors. However, this was not universal, with appreciable adherence to prescribing guidelines in community health centres. Encouragingly, the majority of antibiotics prescribed, albeit often inappropriately, were from the 'Access' group of antibiotics in the AWaRe (Access/Watch/Reserve) classification rather than 'Watch' antibiotics to limit AMR. Inappropriate prescribing of antibiotics in primary care is not helped by concerns with current knowledge regarding antibiotics, AMR and ASPs among prescribers and patients in primary care. This needs to be addressed going forward. However, studies have shown it is crucial for prescribers to use a language that patients understand when discussing key aspects to enhance appropriate antibiotic use. Recommended activities for the future include improved education for all groups as well as regularly monitoring prescribing against agreed-upon guidelines and indicators.

A Multicenter Cross-Sectional Survey of Knowledge, Attitude, and Practices of Healthcare Professionals towards Antimicrobial Stewardship in Ghana: Findings and Implications

Antimicrobial stewardship (AMS) programs are part of the key activities that contribute to reducing antimicrobial resistance (AMR). Good knowledge, attitudes, and practices (KAP) among healthcare professionals (HCPs) are essential to improving future antimicrobial use and reducing AMR, which is a priority in Ghana. A multicenter cross-sectional survey was conducted in six public hospitals in Ghana among key HCPs to assess their level of KAP towards AMS using a validated self-administered electronic questionnaire. Data analyses included descriptive and inferential statistics using STATA version 14. Overall, 339 out of 355 HCPs responded to the questionnaire, giving a response rate of 95.5%. Most responders were nurses (n = 256, 78.2%), followed by medical doctors (n = 45, 13.3%). The study recorded both poor knowledge (8.9%) and practice levels (35.4%), as well as a good attitude (78.8%) towards AMS. Ongoing exposure to AMS structured training, exposure to continuous professional development training on AMS in the previous year, and the number of years of working experience were predictors of the HCPs' level of knowledge (aOR = 3.02 C.I = 1.12-8.11), attitude (aOR = 0.37 C.I = 0.20-0.69) and practice (aOR = 2.09 C.I =1.09-3.99), respectively. Consequently, concentrated efforts must be made to address current low levels of knowledge and poor practices regarding AMS among HCPs in Ghana as part of ongoing strategies in the National Action Plan to reduce AMR.

Ongoing Strategies to Improve Antimicrobial Utilization in Hospitals across the Middle East and North Africa (MENA): Findings and Implications

Antimicrobial resistance (AMR) is an increasing global concern, increasing costs, morbidity, and mortality. National action plans (NAPs) to minimize AMR are one of several global and national initiatives to slow down rising AMR rates. NAPs are also helping key stakeholders understand current antimicrobial utilization patterns and resistance rates. The Middle East is no exception, with high AMR rates. Antibiotic point prevalence surveys (PPS) provide a better understanding of existing antimicrobial consumption trends in hospitals and assist with the subsequent implementation of antimicrobial stewardship programs (ASPs). These are important NAP activities. We examined current hospital consumption trends across the Middle East along with documented ASPs. A narrative assessment of 24 PPS studies in the region found that, on average, more than 50% of in-patients received antibiotics, with Jordan having the highest rate of 98.1%. Published studies ranged in size from a single to 18 hospitals. The most prescribed antibiotics were ceftriaxone, metronidazole, and penicillin. In addition, significant postoperative antibiotic prescribing lasting up to five days or longer was common to avoid surgical site infections. These findings have resulted in a variety of suggested short-, medium-, and long-term actions among key stakeholders, including governments and healthcare workers, to improve and sustain future antibiotic prescribing in order to decrease AMR throughout the Middle East.

A Narrative Review of Healthcare-Associated Gram-Negative Infections Among Pediatric Patients in Middle Eastern Countries

INTRODUCTION

Gram-negative bacteria (GNB) have become prominent across healthcare and community settings due to factors including lack of effective infection control and prevention (ICP) and antimicrobial stewardship programs (ASPs), GNB developing antimicrobial resistance (AMR), and difficulty treating infections. This review summarizes available literature on healthcare-associated infections (HAIs) in Middle Eastern pediatric patients.

METHODS

Literature searches were performed with PubMed and Embase databases. Articles not reporting data on GNB, HAIs, pediatric patients, and countries of interest were excluded.

RESULTS

The searches resulted in 220 publications, of which 49 met the inclusion criteria and 1 additional study was identified manually. Among 19 studies across Egypt reporting GNB prevalence among pediatric patients, Klebsiella species/K. pneumoniae and Escherichia coli were typically the most common GNB infections; among studies reporting carbapenem resistance and multidrug resistance (MDR), rates reached 86% and 100%, respectively. Similarly, in Saudi Arabia, Klebsiella spp./K. pneumoniae and E. coli were the GNB most consistently associated with infections, and carbapenem resistance (up to 100%) and MDR (up to 75%) were frequently observed. In other Gulf Cooperation Council countries, including Kuwait, Oman, and Qatar, carbapenem resistance and MDR were also commonly reported. In Jordan and Lebanon, E. coli and Klebsiella spp./K. pneumoniae were the most common GNB isolates, and AMR rates reached 100%.

DISCUSSION

This review indicated the prevalence of GNB-causing HAIs among pediatric patients in Middle Eastern countries, with studies varying in reporting GNB and AMR. Most publications reported antimicrobial susceptibility of isolated GNB strains, with high prevalence of extended-spectrum beta-lactamase-producing K. pneumoniae and E. coli isolates. A review of ASPs highlighted the lack of data available in the region.

CONCLUSIONS

Enhanced implementation of ICP, ASPs, and AMR surveillance is necessary to better understand the widespread burden of antimicrobial-resistant GNB and to better manage GNB-associated HAIs across Middle Eastern countries.

Association Between Antimicrobial Stewardship Programs and Antibiotic Use Globally: A Systematic Review and Meta-Analysis

IMPORTANCE

Antimicrobial resistance continues to spread rapidly at a global scale. Little evidence exists on the association of antimicrobial stewardship programs (ASPs) with the consumption of antibiotics across health care and income settings.

OBJECTIVE

To synthesize current evidence regarding the association between antimicrobial stewardship programs and the consumption of antibiotics globally.

DATA SOURCES

PubMed, Web of Science, and Scopus databases were searched from August 1, 2010, to Aug 1, 2020. Additional studies from the bibliography sections of previous systematic reviews were included.

STUDY SELECTION

Original studies of the association of ASPs with antimicrobial consumption across health care and income settings. Animal and environmental studies were excluded.

DATA EXTRACTION AND SYNTHESIS

Following the Preferred Reporting Items in Systematic Reviews and Meta-Analyses guideline, the pooled association of targeted ASPs with antimicrobial consumption was measured using multilevel random-effects models. The Effective Public Health Practice Project quality assessment tool was used to assess study quality.

MAIN OUTCOMES AND MEASURES

The main outcome measures were proportion of patients receiving an antibiotic prescription and defined daily doses per 100 patient-days.

RESULTS

Overall, 52 studies (with 1 794 889 participants) measured the association between ASPs and antimicrobial consumption and were included, with 40 studies conducted in high-income countries and 12 in low- and middle-income countries (LMICs). ASPs were associated with a 10% (95% CI, 4%-15%) reduction in antibiotic prescriptions and a 28% reduction in antibiotic consumption (rate ratio, 0.72; 95% CI, 0.56-0.92). ASPs were also associated with a 21% (95% CI, 5%-36%) reduction in antibiotic consumption in pediatric hospitals and a 28% reduction in World Health Organization watch groups antibiotics (rate ratio, 0.72; 95% CI, 0.56-0.92).

CONCLUSIONS AND RELEVANCE

In this systematic review and meta-analysis, ASPs appeared to be effective in reducing antibiotic consumption in both hospital and nonhospital settings. Impact assessment of ASPs in resource-limited settings remains scarce; further research is needed on how to best achieve reductions in antibiotic use in LMICs.

A Comparative Piloting of Determinants of Self-Medication Among University Students in the MENA Region; UAE and Jordan as an Example

PURPOSE

Unsupervised self-medication (SM) is a global public health concern. University students are particularly vulnerable due to misperceptions of improved academic performance and thus are at risk of dependence, addiction, and drug overdose. Past studies have shown an alarming prevalence of SM among university students in the Middle East and North Africa (MENA) region. However, there is a scarcity of reports from the region dissecting determinants of SM. Therefore, this study aimed to determine the prevalence and epidemiological correlates of SM among university students and its perceived impact on their academic performance.

METHODS

Two countries in the MENA region were surveyed in a cross-sectional design; UAE and Jordan. Through a stratified sampling technique, undergraduate students in both healthcare and non-healthcare majors of study were recruited to participate. A structured, self-administered questionnaire developed for the purpose of this study was distributed to consented participants via the university's official email. Statistical analyses were performed using SPSS. Descriptive and inferential statistics were used to analyze data. A p-value <0.05 was considered statistically significant.

RESULTS

A total of 362 students participated in the study (74% were females, 60% were from the UAE, and 59% were in healthcare majors). Significantly higher prevalence rates and adjusted odds of SM were found among females, students from Jordan, and those in healthcare majors, particularly for paracetamol (90.2% of females [p=0.001], 88.3% from Jordan [p=0.03], 92.5% in healthcare majors [p=0.001]) and antibacterial drugs (48.9% of females [p=0.01], 60.7% from Jordan [p=0.001], 53.3% in healthcare majors [p=0.001]). Majoring in healthcare fields was the most consistent determinant of such practice, while social influences of family and friends represented the chief source of recommendation. Only 21% of respondents assumed SM boosts their academic performance.

CONCLUSION

Our pilot study underlines the predominant determinants of SM among university students in the MENA region, namely female gender, students from Jordan, and those in healthcare majors. Informed data-driven awareness campaigns to mitigate such practice should be designed to focus on these susceptible populations.

Current Status of Antibiotic Stewardship and the Role of Biomarkers in Antibiotic Stewardship Programs

The importance of antibiotic stewardship is increasingly emphasized in accordance with the increasing incidences of multidrug-resistant organisms and accompanying increases in disease burden. This review describes the obstacles in operating an antibiotic stewardship program (ASP), and whether the use of biomarkers within currently available resources can help. Surveys conducted around the world have shown that major obstacles to ASPs are shortages of time and personnel, lack of appropriate compensation for ASP operation, and lack of guidelines or appropriate manuals. Sufficient investment, such as the provision of full-time equivalent ASP practitioners, and adoption of computerized clinical decision systems are useful measures to improve ASP within an institution. However, these methods are not easy in terms of both time commitments and cost. Some biomarkers, such as C-reactive protein, procalcitonin, and presepsin are promising tools in ASP due to their utility in diagnosis and forecasting the prognosis of sepsis. Recent studies have demonstrated the usefulness of algorithmic approaches based on procalcitonin level to determine the initiation or discontinuation of antibiotics, which would be helpful in decreasing antibiotics use, resulting in more appropriate antibiotics use.

The Impact of a Post-Prescription Review and Feedback Antimicrobial Stewardship Program in Lebanon

Antimicrobial stewardship programs (ASPs) are effective means to optimize prescribing practices. They are under-utilized in the Middle East where many challenges exist for ASP implementation. We assessed the effectiveness of infectious disease physician-driven post-prescription review and feedback as an ASP in Lebanon. This prospective cohort study was conducted over an 18-month period in the medical, surgical, and intensive care units of a tertiary care hospital. It consisted of three phases: the baseline, intervention, and follow-up. There was a washout period of two months between each phase. Patients aged ≥16 years receiving 48 h of antibiotics were included. During the intervention phase, the AMS team reviewed antimicrobial use within 72 h post-prescription and gave alternate recommendations based on the guidelines for use. The acceptance of the recommendations was measured at 72 h. The primary outcome of the study was days of therapy per 1000 study patient days. A total of 328 patients were recruited in the baseline phase (August−October 2020), 467 patients in the intervention phase (January−June 2021), and 301 patients in the post-intervention phase (September−December 2021). The total days of therapy decreased from 11.46 during the baseline phase to 8.64 during the intervention phase (p < 0.001). Intervention acceptance occurred 88.5% of the time. The infectious disease physician-driven implementation of an ASP was successful in reducing antibiotic utilization in an acute care setting in Lebanon.

Antibiotic Stewardship in Disaster Situations: Lessons Learned in Lebanon

A post-prescription review and feedback program was implemented as an antimicrobial stewardship intervention in Lebanon as the country grappled with complete economic collapse, the COVID-19 pandemic, and a large blast in Beirut. We describe the implications of antimicrobial use in disaster preparedness and crisis situations, the sequelae related to increasing antimicrobial resistance, and our lessons learned in Lebanon. We explore opportunities and potential solutions for future disaster preparedness.

Global Resilience and New Strategies Needed for Antimicrobial Stewardship during the COVID‐19 Pandemic and Beyond

Resilience is having the ability to respond to adversity proactively and resourcefully. The coronavirus disease 2019 (COVID‐19) pandemic's profound impact on antimicrobial stewardship programs (ASP) requires clinicians to call on their own resilience to manage the demands of the pandemic and the disruption of ASP activities. This article provides examples of ASP resilience from pharmacists and physicians from seven countries with different resources and approaches to ASP—The United States, The United Kingdom, Canada, Nigeria, Lebanon, South Africa, and Colombia. The lessons learned pertain to providing ASP clinical services in the context of a global pandemic, developing new ASP paradigms in the face of COVID‐19, leveraging technology to extend the reach of ASP, and conducting international collaborative ASP research remotely. This article serves as an example of how resilience and global collaboration is sustaining our ASPs by sharing new “how to” do antimicrobial stewardship practices during the COVID‐19 pandemic.

What does antimicrobial stewardship look like where you are? Global narratives from participants in a massive open online course

Background

Whilst antimicrobial stewardship (AMS) is being implemented globally, contextual differences exist. We describe how the use of a massive open online course (MOOC) platform provided an opportunity to gather diverse narratives on AMS from around the world.

Methods

A free 3 week MOOC titled ‘Tackling antimicrobial resistance: a social science approach’ was launched in November 2019. Learners were asked specific questions about their experiences of AMS via 38 optional free-text prompts dispersed throughout the modules. Content analysis was used to identify key emerging themes from the learners’ responses in the first three runs of the MOOC.

Results

Between November 2019 and July 2020, 1464 learners enrolled from 114 countries. Overall, 199 individual learners provided a total of 1097 responses to the prompts. The diverse perspectives describe unique challenges present in different contexts including ill-defined roles for pharmacists and nurses in AMS; inadequate governance and policy inconsistencies in surveillance for antibiotic consumption and antimicrobial resistance (AMR) in some countries; lack of ownership of antibiotic decision-making and buy-in from different clinical specialties; and human resource and technological constraints. Patients’ knowledge, experiences and perspectives were recognized as a valuable source of information that should be incorporated in AMS initiatives to overcome cultural barriers to the judicious use of antibiotics.

Conclusions

Analysis of learner comments and reflections identified a range of enablers and barriers to AMS implementation across different healthcare economies. Common challenges to AMS implementation included the role of non-physician healthcare workers, resource limitations, gaps in knowledge of AMR, and patient engagement and involvement in AMS.

Challenges to Antimicrobial Stewardship in the Countries of the Arab League: Concerns of Worsening Resistance during the COVID-19 Pandemic and Proposed Solutions

The COVID-19 pandemic is expected to worsen the global problem of antimicrobial resistance (AMR). There is a heightened interest in understanding this effect and to develop antimicrobial stewardship (AMS) interventions accordingly to curb this threat. Our paper aims to evaluate the potential magnitude of COVID-19 on AMR and AMS with a focus on the countries of the Arab league, given the social, political, and economic environments. We also evaluate obstacles in applying the rational use of antibiotics, monitoring resistance trends in the midst of the pandemic, and evaluating the impact of the economic crisis in some countries. We aim to raise awareness about the potential effects of antibiotic overuse during the pandemic and to propose practical approaches to tackle this issue.

Exploring Information Available to and Used by Physicians on Antibiotic Use and Antibiotic Resistance in Jordan

Evidence based information sources for physicians are needed for informed antibiotic prescribing practices. The aim of this study was to explore physicians' preferred sources of information and evaluate physicians' awareness of available information and initiatives on prudent antibiotic prescribing in Jordan. A cross-sectional study was conducted utilizing an online questionnaire and included physicians (n = 409) from all sectors and specialties in Jordan. Published guidelines (31.8%), the workplace (25.7%), colleagues or peers (20.0%), group or conference training (18.3%), and the medical professional body (18.1%) were the main sources of information about avoiding unnecessary antibiotic prescribing, with the influence of these sources on changing prescribers' views being 34.7%, 17.1%, 11%, 13.4%, and 7.6%, respectively. One-third of physicians (33.7%) reported no knowledge of any initiatives on antibiotic awareness and resistance. Regarding awareness of national action plans on antimicrobial resistance, 10.5%, 34%, and 55.5% of physicians were aware, unaware, and unsure of the presence of any national action plans, respectively. Physicians showed interest in receiving more information on resistance to antibiotics (58.9%), how to use antibiotics (42.2%), medical conditions for which antibiotics are used (41.3%), prescribing of antibiotics (35.2%), and links between the health of humans, animals, and the environment (19.8%). The findings can inform interventions needed to design effective antimicrobial stewardship, enabling physicians to prescribe antibiotics appropriately.
