RESUMEN

Antimicrobial resistance (AMR) poses a significant threat to global health, impairing the efficacy of treatments against various infections. The World Health Organization highlights the impact of AMR on healthcare outcomes, including increased morbidity, mortality, and costs. Vaccination is a pivotal strategy to counter AMR, promoting immune defenses against infections and subsequently reducing the need for antimicrobials. This article assesses the role of vaccination in managing AMR, particularly within the scope of antimicrobial stewardship programs (ASPs), by reviewing the effectiveness of existing vaccination strategies and their integration into the community. A comprehensive literature review was concluded using databases such as Google Scholar, Scielo, and PubMed, analyzing studies from 2005 to 2024. A total of 13 studies were included after screening 132 articles for relevance and eligibility. The studies highlight the substantial role of vaccines in reducing the reliance on antibiotics, especially for vulnerable populations, such as the elderly, children, and those with chronic conditions. For instance, the introduction of conjugate pneumococcal vaccines significantly decreased rates of drug-resistant Streptococcus pneumoniae infections. The review also discusses the indirect benefits of widespread vaccination, including herd immunity and decreased transmission of resistant strains. Vaccination is a critical element in the fight against AMR. Well-coordinated ASPs, by facilitating comprehensive vaccination programs, can significantly mitigate the rise of resistant infections, optimize antimicrobial usage, and improve patient outcomes in healthcare settings. The strategies outlined reflect global health objectives and emphasize the need for sustained efforts to enhance vaccine coverage and acceptance.

RESUMEN

BACKGROUND: With the advent of multiplex polymerase chain reaction (PCR) using samples from a positive blood culture, the time required to identify a pathogen has significantly shortened to a few hours. It can help us select appropriate antimicrobial agents more quickly. The present study aimed to assess the impact of using a multiplex PCR blood culture panel on the appropriate administration of antimicrobial agents. METHODS: Patients aged <16 years with culture-confirmed bacteremia at Tokyo Metropolitan Children's Medical Center were enrolled. A pre-intervention period (period I: December 2016 to December 2018) and a post-intervention period with multiplex PCR use for the confirmation of positive blood cultures (period II: December 2019 to December 2021) were compared for their effect on the use of antimicrobial agents for gram-positive cocci (GPC) and gram-negative rod (GNR) bacteremia. Data on patient background, blood culture results, and antimicrobial use were retrospectively collected from electronic medical records. RESULTS: Periods I and II had 174 and 154 patients, respectively. The median age at periods I and II was 14 (IQR 2-82) months and 12 (IQR 1-78) months, respectively. GPC bacteremia during periods I and II occurred in 140 and 115 patients, respectively. GNR during periods I and II occurred in 34 and 39 patients, respectively. Neither the vancomycin-resistance genes A/B nor the carbapenem-resistance gene were detected. The use of antimicrobial agents against anti-methicillin-resistant Staphylococcus aureus (MRSA) for GPC bacteremia decreased from 103/140 cases (73%) in period I to 56/115 cases (49%) in period II (p=0.047). The use of carbapenems for GNR bacteremia did not change significantly, at 23/34 (68%) in period I and 34/39 (87%) in period II (p=0.47). CONCLUSION: Introducing multiplex PCR for pediatric bacteremia decreased the use of anti-MRSA antimicrobial agents but not of carbapenems.

RESUMEN

BACKGROUND: AWaRe (Access, Watch, Reserve) classification proposed by the World Health Organization (WHO) holds potential for assessing antimicrobial stewardship programs (ASPs). However, increase in antibiotics for non-infectious treatment might undermine the effectiveness of using the AWaRe classification for assessing ASPs. The study aimed to evaluate the antimicrobial usage by AWaRe classification and specify issues for assessing ASPs. METHODS: The retrospective study was conducted in a single center within an 845-bed hospital. Antimicrobial usage data for outpatients were obtained from medical records used for billing purposes. Antimicrobials for non-infectious treatment were defined by smaller dose of macrolides, tetracyclines with pemphigoid, rifaximin, and prophylactic sulfamethoxazole-trimethoprim (ST) agent. RESULTS: The usage of antimicrobials for non-infectious treatment increased from 25.3 % to 50.1 % for the ratio of the amount to defined daily doses (DDDs) and from 46.3 % to 65.9 % for prescription days between January 2015 and March 2024. The usage of prophylactic sulfamethoxazole-trimethoprim (ST) agents increased by 2.4 times, and the usage of rifaximin increased by more than 100 times. Macrolides for non-infectious treatment was stable or fluctuated while that for infection treatment decreased to that amount for non-infectious treatment. The ratios for Access increased from 31.9 % to 58 % and 42 % to 78 % by excluding the antimicrobials for non-infectious treatment. CONCLUSIONS: The findings suggested that the AWaRe classification might not be appropriate for assessing ASPs and comparing them among hospitals.

RESUMEN

Background Antimicrobial resistance (AMR) is caused by inappropriate use of antimicrobials. India's high antibiotic use contributes significantly to AMR. Antimicrobial Stewardship Programs (AMSPs) are crucial for optimizing antimicrobial use. Knowledge, Attitude, and Practice (KAP) studies are essential for evaluating healthcare professionals' beliefs and conduct regarding AMR and AMSPs. Materials and methods A cross-sectional study at Saveetha Medical College and Hospital evaluated doctors' knowledge, attitudes, and practices regarding AMR and stewardship programs. The study involved 202 participants, including faculty members, postgraduates, and interns. Results The study involved 202 participants, with residents being the majority at 51.4%, followed by faculty at 26.7% and interns at 21.7%. Faculty members showed the highest overall knowledge, followed by residents and interns. Despite possessing knowledge, practitioners did not consistently implement their knowledge in their daily practices, with a statistically significant difference of p < 0.01. There was a substantial disparity in attitude between the departments, as evidenced by a statistically significant p-value of less than 0.01. Conclusion Positive trends in knowledge and attitudes exist, but there are areas for improvement in translating attitudes into clinical practices. There is a significant disparity among faculty members, residents, and interns, highlighting the urgent need for interventions to bridge the gap. Implementing antibiotic prescribing guidelines at the institutional level and enhancing knowledge, attitudes, and practices among healthcare professionals are crucial to addressing AMR.

RESUMEN

Timely pathogen identification in bloodstream infections is crucial for patient care. A comparison is made between positive blood culture (BC) pellets from serum separator tubes using a direct identification (DI) method and colonies on agar plates from a short-term incubation (STI) method with a matrix-assisted laser desorption/ionization Biotyper for the evaluation of 354 monomicrobial BCs. Both the DI and STI methods exhibited similar identification rates for different types of bacteria, except for Gram-positive and anaerobic bacteria. The DI method's results aligned closely with the STI method's results for Enterobacterales, glucose-non-fermenting Gram-negative bacilli (GNB), and carbapenem-resistant Enterobacterales. The DI method exhibited high concordance with the conventional method for GNB identification, achieving 88.2 and 87.5% accuracy at the genus and species levels, respectively. Compared with the STI method, the DI method showed a less successful performance for Gram-positive bacterial identification (50.5 vs. 71.3%; p < 0.01). The DI method was useful for anaerobic bacterial identification of slow-growing microorganisms without any need for colony growth, unlike in the STI method (46.7 vs. 13.3%; p = 0.04). However, both methods could not identify yeast in positive BCs. Overall, the DI method provided reliable results for GNB identification, offering many advantages over the STI method by significantly reducing the turnaround time and enabling quicker pathogen identification in positive BCs.

RESUMEN

Introduction: Recently, antimicrobial resistance has received considerable attention. Broad-spectrum antimicrobial agents are recommended as the initial therapy for post-operative intra-abdominal infections. However, at our institution, we have adopted a tactic of initially treating post-operative intra-abdominal complications with relatively narrow-spectrum antimicrobial agents, such as second-generation cephalosporins. In the present study, we aimed to retrospectively analyze the use of antimicrobial agents and the resulting treatment outcomes in patients with intra-abdominal complications after gastrectomy at our facility. Methods: We conducted a retrospective observational study of patients treated with antibiotic agents for intra-abdominal infectious complications after gastrectomy between 2011 and 2021. We determined the proportion of "initial treatment failures" associated with the initial administration of antibiotic agents for post-operative intra-abdominal complications. Results: Post-operative intra-abdominal infections were observed in 29 patients. Broad-spectrum antimicrobial agents were not administered. We successfully treated 19 patients. Initial treatment failure was observed in 10 patients, of whom five experienced failure due to bacterial resistance to the initial antimicrobial agent. All 10 patients who experienced initial treatment failure were discharged after drainage procedures or other treatments. There were no deaths due to post-operative complications. Cefmetazole was used as the initial antimicrobial agent in 27 of the 29 patients. Conclusions: Considering that all patients with post-gastrectomy intra-abdominal infections were successfully treated using relatively narrow-spectrum antimicrobial agents, and initial treatment failure due to antimicrobial-resistant pathogens was 17.2%, the use of narrow-range antimicrobial agents for intra-abdominal infections after gastrectomy can be deemed appropriate.

RESUMEN

Laboratories with a well-established diagnostic stewardship program for culture and the antimicrobial susceptibility test (C-AST) play a key role in guiding clinicians to institute specific targeted therapy. Blood culture is one of the most critical investigations performed at a microbiology laboratory. Therefore, it is particularly important to develop a robust diagnostic stewardship model for the blood culture laboratory division. Aiming at this hypothesis, this hospital-based clinical audit carried out within the Department of General Medicine, centered on the critical domain of antimicrobial stewardship (AMSP). The audit's primary objective was to systematically evaluate prevailing practices and pinpoint areas necessitating refinement in the administration of antimicrobial agents. Employing a meticulous approach involving exhaustive data scrutiny and feedback mechanisms, the audit unearthed strategic opportunities to optimize prescription patterns, curtail unwarranted antimicrobial utilization, and fortify adherence to established guidelines. The subsequent execution of targeted interventions, encompassing educational initiatives and routine performance feedback, culminated in a noteworthy enhancement of antimicrobial prescribing practices. These outcomes unequivocally underscore the efficacy of the audit in cultivating a milieu of judicious antimicrobial utilization, thereby augmenting patient care and mitigating antibiotic resistance within the department.

RESUMEN

Antimicrobial resistance (AMR) poses a significant threat to global health, compromising the effectiveness of treatments and increasing medical risks. In this crisis, the importance of vaccines in reducing AMR is being increasingly acknowledged, although not thoroughly explored. This literature review asserts that vaccines can significantly lessen the occurrence of infections, thereby reducing the need for antibiotics and limiting the emergence of resistance. Vaccines play a crucial role in antimicrobial stewardship programs by preventing diseases that would otherwise necessitate the use of antibiotics. Expanding vaccine coverage supports responsible usage of antimicrobials and aligns with global health priorities to maintain effective medical interventions. This review emphasizes the need for equitable funding and policy support for vaccine initiatives comparable to new antibiotics and diagnostic techniques. Moreover, it calls for more detailed investigations into vaccines' economic and health benefits in managing AMR, highlighting their potential as cost-effective solutions to this urgent health challenge. Through a careful analysis of existing literature, this review highlights the fundamental role of vaccines in transforming the landscape of AMR, shifting the focus from a protective approach to a preventive health strategy.

RESUMEN

BACKGROUND: We aimed to analyze the effects of an antimicrobial stewardship program (ASP) on the proportion of antimicrobial-resistant pathogens in bacteremia, antimicrobial use, and mortality in pediatric patients. METHODS: A retrospective single-center study was performed on pediatric inpatients under 19 years old who received systemic antimicrobial treatment from 2001 to 2019. A pediatric infectious disease attending physician started ASP in January 2008. The study period was divided into the pre-intervention (2001-2008) and the post-intervention (2009-2019) periods. The amount of antimicrobial use was defined as days of therapy per 1,000 patient-days, and the differences were compared using delta slope (= changes in slopes) between the two study periods by an interrupted time-series analysis. The proportion of resistant pathogens and the 30-day overall mortality rate were analyzed by the χ². RESULTS: The proportion of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae bacteremia increased from 17% (39 of 235) in the pre-intervention period to 35% (189 of 533) in the post-intervention period (P < 0.001). The total amount of antimicrobial use significantly decreased after the introduction of ASP (delta slope value = -16.5; 95% confidence interval [CI], -30.6 to -2.3; P = 0.049). The 30-day overall mortality rate in patients with bacteremia did not increase, being 10% (55 of 564) in the pre-intervention and 10% (94 of 941) in the post-intervention period (P = 0.881). CONCLUSION: The introduction of ASP for pediatric patients reduced the delta slope of the total antimicrobial use without increasing the mortality rate despite an increased incidence of ESBL-producing gram-negative bacteremia.

RESUMEN

Introduction: Antimicrobial resistance (AMR) is becoming a threat to global public health. Antimicrobial stewardship (AMS) program (ASP) is one of the 5 strategic areas in the Ghana National Action Plan to fight this menace. Assessment of the core elements of ASP in a hospital setting has been identified as a pragmatic way of identifying the barriers and facilitators for its effective implementation. Method: The World Health Organization's toolkit for assessment of the 7 core elements of ASP in hospitals in low and middle income countries was used for this situational analysis of public hospitals in 2 regions of Ghana. The core elements included leadership commitment, accountability and responsibility, pharmacy expertize, AMS actions and interventions, education and training, and periodic monitoring and surveillance. Data collected using a checklist were imported into STATA version 14 for descriptive and bivariate analyses. Results: 15 public hospitals were assessed with the toolkit. Most of them were primary health care facilities (n = 12, 80.0%), had bed capacities between 100 and 199 beds, less than 50 medical doctors (n = 12, 80.0%), less than 5 pharmacists (n = 10, 66.7%), and between 100 and 199 nurses. Performances in 4 out of the 7 core elements were most deficient and they included leadership commitment, pharmacy expertize, AMS actions (interventions) implemented, monitoring and surveillance of antibiotic use, and bacteria resistance rates. Pharmacist-led ASPs were also found to be associated with their formal training on AMS. Key barriers identified included lack of skilled human resources, lack of available time for AMS-related duties and poor laboratory infrastructure. Conclusion: There was sub-optimal performance for almost all the core elements of ASP in the public hospitals in Ghana hampered mostly by lack of skilled human and financial resources. Pharmacists must be empowered through formal training and certificate programs in infectious disease management and AMS principles and strategies to enhance their contribution toward ASPs in hospitals. The results from this study should encourage nationwide assessment of ASPs across hospital settings in Ghana to better evaluate the level of their implementation and address potential barriers to guide AMS policies and ASP strategy development toward the fight against AMR.

RESUMEN

A retrospective study at the 4th Military Clinical Hospital in Wroclaw, Poland, assessed PCR testing alongside blood cultures to guide antimicrobial therapy decisions in hospitalized patients, to determine how much time the results of the molecular tests preceded conventional methods. Among 118 patients, Staphylococcus aureus (37%) and Escherichia coli (21%) were the most common bloodstream infection agents. Blood cultures utilized the BacT/ALERT 3D system, and molecular diagnostics were conducted using the FilmArray platform with the BIOFIRE BCID2 panel. Methicillin susceptibility was observed in 66% of S. aureus strains, while 26% of Gram-negative bacilli exhibited an ESBL phenotype. Therapeutic decisions based on molecular test results were often incorrect for S. aureus infections, particularly MSSA (64.5%), but generally accurate for Gram-negative bacilli. The median times from positive blood culture to BCID2 and pathogen identification/susceptibility were 10 h and 52 h, respectively. Molecular diagnostics facilitated faster initiation of appropriate antibiotic therapy, highlighting the need to educate medical staff on proper interpretation. Consulting within an antimicrobial stewardship program (ASP) could enhance the benefits of implementing molecular methods in bloodstream infection diagnostics.

RESUMEN

BACKGROUND: Antimicrobial stewardship (ASP) is considered a key prevention strategy in addressing the worldwide concern of accelerating antimicrobial resistance. Limited research is available regarding healthcare providers' knowledge and attitude toward antimicrobial stewardship and the barriers for its implementation. METHODS: The present cross-sectional study was conducted on pharmacists and healthcare prescribers (HCPs) in different hospital sites across Jordan. A validated survey was used to evaluate HCPs and pharmacists' knowledge, and attitudes towards ASP and the barriers for its implementation. Logistic and linear regression were conducted to identify the factors associated with knowledge and attitude toward ASP, respectively. RESULTS: A total of 603 participants, 69 (11.4%) pharmacists and 534 (88.6%) HCPs completed the study questionnaire, with a response rate of 80.4%. The overall mean knowledge about ASP was 7.16 out of 10, ranging from 0 to 10 (SD 2.22). Being a pharmacist and increased awareness/familiarity about ASP were associated with improved ASP knowledge. The overall average attitude score was = 3.8 ± 0.49 (range: 1.8-4.8). Results revealed that being a pharmacist and improved knowledge were associated with improved attitude toward ASP. Lack of specialized staff with expertise in ASP and lack of access to education and training programs were the major barriers hinder ASP implementation. CONCLUSION: Despite the reasonable knowledge and the positive attitude toward the ASP, several barriers were reported, particularly by the pharmacists. Therefore, promoting the presence of adequately skilled healthcare personnel, creating easily accessible online courses, and establishing a comprehensive database of ASP resources are all suggested approaches to improve the application of ASP in healthcare settings.

RESUMEN

BACKGROUND: Antimicrobial resistance is associated with increasing mortality rates and the emergence of multidrug-resistant (MDR) organisms. There is scarcity of data on the short-term impact of Antimicrobial Stewardship Programs (ASP) on antibiotic usage, clinical outcome and MDR organisms' pattern following the COVID-19 pandemic. This study evaluated the short-term effects of ASP on antibiotic usage, clinical outcomes and MDR organisms' pattern in the post COVID-19 era. METHODS: Conducted at a tertiary academic health center, this observational study involved adult patients (≥18 years) in the general medical unit, treated with oral or intravenous antibiotics from May 1, 2021, to April 30, 2022. The applied ASP strategy was a prospective audit and feedback where a weekly meeting was held to discuss the antimicrobial therapy of admitted patient, after which recommendations were made regarding antimicrobial use. RESULTS: The study included 301 patients with 166 (55.1%) pre-ASP and 135 (44.9%) post-ASP. The median (IQR) age was 69 (55-77) years with 56.1% were female. Antibiotic usage dropped by 25.2% post-ASP. The length of hospital stay (LOS) was longer post-ASP (7 days vs. 7.9 days, p = 0.001), with MDR infections being a significant predictor (OR: 0.486, p < 0.001). There were no significant differences in 28-day readmission, recurrence of infections and all-cause mortality. Post-ASP, MDR pathogens increased (17.0% vs. 6.6%, p = 0.013), however, after separating post-ASP into two three-months periods, MDROs numbers decreased slightly (13 vs. 10). CONCLUSION: Short-term ASP implementation post COVID-19 reduced antibiotic usage while other clinical outcomes remained unchanged. Nonetheless an increase in MDR pathogens and LOS was observed. Further research is required to assess ASP's long-term impact on MDR infections rates and specific patient group outcomes.

RESUMEN

INTRODUCTION: One of the main causes of illness, mortality, and rising medical costs is antimicrobial resistance, which is a global healthcare concern. OBJECTIVES: This study explores the practice of physicians toward the effective implementation of Antibiotic Stewardship Programs (ASPs) in Najran city, Saudi Arabia. METHODOLOGY: This cross-sectional study was conducted among physicians working at primary care setting in Najran city, Saudi Arabia, between May and August 2023. A self-administered questionnaire was distributed among the physicians composed of three parts: socio-demographic data, a questionnaire about physicians' practice in the efficacy of ASP, and a questionnaire about physicians' practice regarding prescribing antibiotics. RESULTS: Of the 128 physicians who participated in the study, 60.2% were males, and 43.8% were aged between 36 and 45 years. Among the practices in implementing the ASP effectively, controlling the source of infection domain received the highest score (mean score: 4.83). Every practice domain mean score was greater than 3, indicating that study participants possessed a moderate level of ASP practice and implementation skills. The overall mean practice score in the effective implementation of ASP was 154.9 ± 25.5 out of 185 points, with good, moderate, and poor practices constituting 67.2%, 28.1%, and 4.7%, respectively. CONCLUSIONS: The physicians showed a moderate level of practice for the effective implementation of ASPs in Najran city. The factors significantly associated with increased practice score include older age, male gender, Saudi nationality, handling five or fewer infection cases daily, and infection-initiated antibiotic prescribing treatment managed per day. These findings suggest the need for targeted interventions and educational programs to enhance physicians' adherence to ASP guidelines and promote appropriate antibiotic prescribing practices, ultimately contributing to global efforts in combating antimicrobial resistance and improving patient outcomes.

RESUMEN

BACKGROUND: Antimicrobial stewardship programs (ASPs) are pivotal components of the World Health Organization's Global Action Plan to combat antimicrobial resistance (AMR). ASPs advocate rational antibiotic usage to enhance patient-centered outcomes. However, existing evidence on ASPs and their determinants is largely limited to well-equipped hospitals in high-income nations. OBJECTIVE: This scoping review aimed to examine the current state of hospital-based ASPs in low- and middle-income countries (LMICs), shedding light on barriers, facilitators, prescribers' perceptions and practices, and the impact of ASP interventions. DESIGN: Scoping review on ASP. METHODS: Adhering to PRISMA guidelines, we conducted electronic database searches on PubMed, Scopus, and Google Scholar, covering ASP articles published between January 2015 and October 2023. Our review focused on four key domains: barriers to ASP implementation, facilitators for establishing ASP, ASP perceptions and practices of prescribers, and the impact of ASP interventions. Three reviewers separately retrieved relevant data from the included citations using EndNote 21.0. RESULTS: Among the 7016 articles searched, 84 met the inclusion criteria, representing 34 LMICs. Notably, 58% (49/84) of these studies were published after 2020. Barriers to ASP implementation, including human-resources shortage, lack of microbiology laboratory support, absence of leadership, and limited governmental support, were reported by 26% (22/84) of the studies. Facilitators for hospital ASP implementation identified in five publications included the availability of antibiotic guidelines, ASP protocol, dedicated multidisciplinary ASP committee, and prompt laboratory support. The majority of the research (63%, 53/84) explored the impacts of ASP intervention on clinical, microbiological, and economic aspects. Key outcomes included increased antibiotic prescription appropriateness, reduced antimicrobial consumption, shorter hospital stays, decreased mortality rate, and reduced antibiotic therapy cost. CONCLUSIONS: The published data underscores the imperative need for widespread antimicrobial stewardship in LMIC hospital settings. Substantial ASP success can be achieved through increasing human resources, context-specific interventions, the development of accessible antibiotic usage guidelines, and heightened awareness via training and education.

RESUMEN

INTRODUCTION: Antimicrobial resistance is a global issue, and implementation of antimicrobial stewardship programs in outpatient settings is crucial. Japan has also focused on outpatient oral antimicrobial stewardship programs and difficulties in standardizing prescriptions have led to overprescription in primary emergency medical centers. There is a lack of research investigating the antibiotic prescription status of pediatric primary emergency medical centers and the benchmark prescription rates in pediatric outpatient settings. METHODS: We conducted a multi-center, cross-sectional study of seven pediatric primary emergency medical centers located in five prefectures of Japan. We retrospectively extracted data from health claims or directly obtained them from charts at each institution and evaluated trends in the antibiotic prescription rate based on the AWaRe classification between April 2016 and December 2019. RESULTS: Our study included 383,525 encounters, with the most common infectious disease diagnosis being acute upper respiratory tract infection in 93,449 cases (24.4 %). The antibiotic prescription rate during the study period was 7.4 %, representing a decrease of 46 %, from 10.2 % in 2016 to 5.5 % in 2019. The percentage of prescriptions in the Access group increased at all institutions; however, it exceeded 60 % in only three facilities in 2019. The percentage of third-generation cephalosporins varied among facilities, ranging from 1.7 % to 59.4 %, as of 2019. CONCLUSIONS: For pediatric primary emergency medical centers where antimicrobial stewardship programs are implemented, we suggest 5 % as a reasonable benchmark level for the antibiotic prescription rate. Prescribing the antibiotics in the Access groups less frequently remains a domestic challenge in Japan.

RESUMEN

Objective The novel coronavirus disease 2019 (COVID-19) pandemic has spread worldwide, and hospitals in Japan have been forced to respond to the situation. This study evaluated the broad-spectrum antimicrobial use before and during the COVID-19 pandemic in an acute tertiary-care hospital. Methods This single-center, retrospective study was conducted between January 2019 and June 2021. Patients We reviewed patients treated with three broad-spectrum antipseudomonal agents: carbapenems, tazobactam/piperacillin, and cefepime. Monthly aggregated hospital antimicrobial consumption was measured as days of therapy (DOTs) per 1,000 patient-days, and the monthly incidences of Clostridioides difficile infection (CDI), multidrug-resistant Pseudomonas aeruginosa (MRPA), and carbapenemase-producing Enterobacteriaceae (CPE) were recorded. Results The median monthly carbapenem-DOTs during the pre-pandemic and pandemic era were 8.4 and 8.2 per 1,000 patient-days, respectively. A time-series analysis showed non-significant changes in the level between periods (coefficients: 2.08; 95% confidence interval [CI]: -2.9 to 7.0; p=0.44). No change in the trend of monthly carbapenem-DOTs was observed after intervention. No post-intervention changes in the incidence of MRPA or CPE were observed; however, the trend in the incidence of CDI per 1,000 patient-days significantly differed between the two periods (coefficient: -0.04; 95% CI: -0.07, 0.00; p=0.01), and a downward trend was observed in the monthly CDI incidence during the COVID-19 period. Conclusion The consumption of broad intravenous antimicrobial agents has not changed significantly during the pandemic. We need to maintain the quality of medical care, including antimicrobial stewardship, even in specialized resource-limited facilities during a pandemic.

RESUMEN

The misuse of antibiotics in veterinary practices by farmers is harming livestock production and food safety and leading to the rise of antibiotic resistance (AMR). This can also transfer resistant bacteria from animals to humans, posing a serious public health threat. However, we have not paid enough attention to understanding how farmers behave in this regard. Our study aims to explore farmers' behaviors and identify the factors that influence their choices. To conduct this study, we used a questionnaire with 40 questions and surveyed 208 farmers in Jhunjhunu district, Rajasthan. We analyzed the data using SPSS. Here are the key findings: About 58.3% of the farmers have some awareness of antibiotics, and 49.5% are aware of antimicrobial resistance (AMR). Notably, as the level of education increases, so does awareness of antibiotics. Unfortunately, 63.9% of the farmers are not aware of the withdrawal time, and 64% have no idea about the presence of antibiotic residues during this period. Around 75% of farmers vaccinate their animals, but approximately 56.9% of individuals have never undergone an antibiotic sensitivity test (ABST) for milk. Around 48.6% of farmers are unaware of government testing centers. Several factors hinder farmers from implementing proper animal management practices, such as the high fees of veterinarians. When their animals become sick, their first choice is home remedies, followed by using old prescriptions. Additionally, 63.9% stop treatment once the animal looks better. A significant portion (83.8%) of farmers rely on local pharmacists for medicine. It has been determined that there is no significant correlation between education, experience, age, and the level of awareness concerning withdrawal periods, the existence of government antibiotic sensitivity test (ABST) centers, and entities responsible for sending samples for ABST. In our qualitative analysis, focus groups identified significant barriers to following best farm practices and spreading awareness about AMR. These findings suggest that addressing AMR in livestock requires a comprehensive approach. This should include targeted education and awareness programs for farmers, as well as improved access to veterinary services.

RESUMEN

We analyzed the accuracy and time efficiency of the FilmArray blood culture identification (FA-BCID) panel in identifying the pathogens in positive blood cultures. Two-hundred and seventy-two individuals were randomly assigned as the control (n = 212) and FA-BCID (n = 60) groups participating in this study. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was used to assess the control group. Meanwhile, the FA-BCID group was evaluated using both FA-BCID and MALDI-TOF, and the results were compared. The identification results from 73% (44/60) of the blood samples demonstrated agreement between FA-BCID and MALDI-TOF. The FA-BCID panel detected mecA genes in seven Staphylococcus species; six cases were confirmed using antimicrobial susceptibility testing. In addition, KPC genes were detected in one Escherichia coli and one Klebsiella pneumoniae, although only the latter corresponded with the result from antimicrobial susceptibility testing. The turnaround time (TAT) for identification through FA-BCID was shorter, with a median of 3.6 [2.4-4.6] hours (p < 0.05). No significant differences in the clinical and microbial outcomes following the ASP were observed between FA-BCID and MALDI-TOF. These results suggest that the FA-BCID panel provides an identification result that is as reliable as that provided by the routine identification procedure but with shorter TAT; thus, the FA-BCID method is considered an effective and beneficial method for therapeutic decision making and the improvement of the ASP for patients with bloodstream infection.

Objective. We aim to evaluate the adherence rate to an Antimicrobial Stewardship Program (ASP) in an Intensive Care Unit (ICU), and to assess its effect on the use of antibiotics, quality indicators and clinical outcomes. Patients and methods. Retrospective description of the interventions proposed by the ASP. We compared antimi crobial use, quality and safety indicators in an ASP versus a non-ASP period. The study was performed in a polyvalent ICU of a medium-size University Hospital (600 beds). We studied patients admitted to the ICU for any cause during the ASP pe riod, provided that a microbiological sample aiming to diag nose a potential infection has been drawn, or antibiotics have been started. We elaborated and registered of non-mandatory recommendations to improve antimicrobial prescription (audit and feedback structure) and its registry during the ASP peri od (15 months, October 2018-December 2019).
