In Zambia, there is little information documented regarding the knowledge, attitude, and practices of poultry farmers on AMU and AMR. Therefore, this study assessed the knowledge, attitude and practices regarding AMU and AMR among poultry farmers in Kitwe, Zambia. Methods: This was a cross-sectional study conducted among 106 poultry farmers from November to December 2021 using a structured questionnaire. Data analysis was done using IBM Statistical Package for Social Sciences (SPSS) version 26. Results: Overall, of the 106 participants, 90.6% knew what antimicrobials were, but only 29.2% were aware of AMR. The study showed that 46.2% of the participants had low knowledge, 71.7% had negative attitudes, and 61.3% had poor practices regarding AMR. The prevalence of antibiotic use in poultry production was 83%. The most used antimicrobials were tetracycline (84%) and gentamicin (35.2%). The commonly reported reason for the use of antimicrobials was for the treatment (93.2%) and prevention (89.8%) of diseases. Further, 76.9% of the administered antimicrobials were usually done without veterinarian consultation or prescription. Conclusion: The study shows that there was high AMU in poultry farms in Kitwe. However, there was low knowledge, negative attitude, and poor practices towards AMU and AMR. Therefore, there is a need for educational and sensitisation programmes regarding AMU and AMR among poultry farmers in Kitwe, Zambia. Alongside this, antimicrobial stewardship and surveillance systems should be strengthened in the livestock production sector. This will ensure food safety and public health.展开更多

Pharmacy staffs have pivotal roles in facilitating the prudent use of antibiotics through antimicrobial stewardship programs. Due to limited information in Benin, this study assessed the knowledge and attitudes of pharmacy staffs on antibiotic use and resistance. Materials and Methods: This cross-sectional study was conducted among 159 pharmacy staffs using a structured questionnaire from August 2018 to December 2018 in Benin. Data analysis was done by using Stata version 13.0. Results: Of the 159 participants, 54.8% knew the definition of antibiotic therapy and 66.9% knew the definition of probabilistic antibiotic therapy. The majority (88.1%) of the participants thought that the choice of antibiotics was made according to the pathology, while 60.4% thought that it depended on the pathology and the germ involved. 49.02% of dispensers in pharmacies stated that half of the patients had requested treatment without providing a prescription at the pharmacy. The top three antibiotics that were dispensed without a prescription include amoxicillin (98.1%), cloxacillin (76.7%) and metronidazole (57.2%), all from the Access group of antibiotics. Conclusion: These results underscore the need for educational and training interventions targeting specific professional groups. There is an urgent need for regulatory measures and public awareness through improved antimicrobial stewardship to limit this practice.展开更多

As part of efforts to combat AMR, the World Health Organization has identified Antimicrobial Stewardship as one of the strategic objectives of its global action plan on antimicrobial resistance. This survey aimed to observe antimicrobial prescribing and usage patterns in the Rivers State University Teaching Hospital with the purpose of identifying gaps to inform the specific antimicrobial stewardship interventions necessary to address our specific needs. Methodology: A point prevalence survey was conducted using the protocol and web-based automated data management system designed by the Global Point Prevalence Survey of Antimicrobial Consumption and Resistance, University of Antwerp, Belgium, in November 2021. Results: A total of 69 adult medical and surgical patients were surveyed;27 males and 18 females. Antimicrobial prevalence was 65.2%. Third generation cephalosporins (24.4%;33.3%), fluoroquinolones (17.8%;22.2%) and imidazole derivatives (20%;36.1%) were most prescribed on the medical and surgical wards. Antimicrobial guidelines were completely unavailable, most antimicrobials (93.8%) were prescribed empirically and 64.4% of these remained empirical after 72 hours of commencement. Conclusion: Antimicrobial stewardship interventions are necessary to minimize sub-optimal antimicrobial prescribing practices in our facility. Most critical are education on appropriate use of antimicrobials, support for development of antimicrobial guidelines, diagnostic stewardship, and the drive for improved use of the laboratory to guide antimicrobial prescriptions. The antimicrobial stewardship committee and team must drive this, having the requisite support from the management and prescribers, with the primary outcomes being reduced antimicrobial prevalence and improved antimicrobial prescription patterns.展开更多

Antibiotic stewardship programmes(ASPs) aim to optimise appropriate antibiotic treatment whilst minimising antibiotic resistance. Different models of ASP in intensive care setting, include "standard" control of antibiotic prescribing such as "de-escalation strategies"through to interventional approaches utilising biomarkerguided antibiotic prescribing. A systematic review of outcomes related studies for ASPs in an ICU setting was conducted. Forty three studies were identified from MEDLINE between 1996 and 2014. Of 34 nonprotocolised studies, [1 randomised control trial(RCT), 22 observational and 11 case series], 29(85%) were positive with respect to one or more outcome: These were the key outcome of reduced antibiotic use, or ICU length of stay, antibiotic resistance, or prescribing cost burden. Limitations of non-standard antibiotic initiation triggers, patient and antibiotic selection bias or baseline demographic variance were identified. All 9 protocolised studies were RCTs, of which 8 were procalcitonin(PCT) guided antibiotic stop/start interventions. Five studies addressed antibiotic escalation, 3 de-escalation and 1 addressed both. Six studies reported positive outcomes for reduced antibiotic use, ICU length of stay or antibiotic resistance. PCT based ASPs are effective as antibiotic-stop(de-escalation) triggers, but not as an escalation trigger alone. PCT has also been effective in reducing antibiotic usage without worsening morbidity or mortality in ventilator associated pulmonary infection. No study has demonstrated survival benefit of ASP. Ongoing challenges to infectious disease management, reported by the World Health Organisation global report 2014, are high AMR to newer antibiotics, and regional knowledge gaps in AMR surveillance. Improved AMR surveillance data, identifying core aspects of successful ASPs that are transferable, and further well-conducted trials will be necessary if ASPs are to be an effective platform for delivering desired patient outcomes and safety through best antibiotic policy.展开更多

Basically, this approach directs the management of antimicrobials in terms of selection of appropriate drugs, determination of administration routes and standardization of both medication dosage and treatment duration. The program involves, but is not limited to, Hospital Staff Education, Pharmacodynamics Dose Optimization, Computer-Assisted Decision Support Programs, Pharmacist-Driven Intravenous to Oral Switch Programs, Pharmacy Dosing Programs and Antibiotic Cycling. A study was conducted to determine effectiveness of the ASP in significantly improving patient outcomes (e.g. decrease morbidity and mortality from infection). This was undertaken by collecting restrospective data on patient length of hospital stay, bed turnover rate and antibiotic consumption over a period of 2 years since the ASP was initiated. Periodic data were then compared and interpreted based on its clinical, quality and financial implications in order to measure effectiveness of the program implementation.展开更多

Some managers respond to human disturbance of sensitive species by closing beaches, but most have stewards monitor and restrict access to beaches or portions of beaches.

While most people came to see the shorebird and horseshoe crab spectacle (60%), many came for the scenery, tranquility, and recreation. Just over half of the people interviewed said that the stewards were helpful (58%), although most of those that answered this question later said that they provided conservation value (86%), but only 40% said they relied on the stewards for information. On a Likert rating scale of 1 to 5 (the highest value), the mean rating for whether it was important for stewards to be present was 3.87 ± 0.09, and the rating for the presence of stewards who can provide information was 3.71 ± 0.11. In contrast, protection of shorebirds was rated a mean of 4.79 ± 0.04. There were significant visitor type differences in how important stewards were, but not in the importance of stewards who can provide information. Fishermen, recreationists, and people coming for scenery and tranquility rated the presence of stewards higher than those visitors who were interested in either shorebirds or crabs (or both). Ratings also differed significantly as a function of age and gender;older adults and females rated characteristics higher than did people under 30 years and males. Information needs identified by stewards are also discussed. These data can be used by the managers developing a strategy for conservation of shorebirds and other species sensitive to disturbance, and for the implementation of an effective stewardship program.展开更多

Methods This study was carried out in the Pediatric Center of a tertiary hospital of Shandong Province, China. The study duration was separated into two periods according to introduction of ASP (began from April 2011). Before intervention: from April 2009 to March 2011;after intervention: from April 2012 to March 2014. The consumption of antibiotics, defi ned daily dose (DDD), isolation of multidrug-resistant organisms (MDRO) and resistance rate of antibiotics were analyzed and compared between the two study periods. Results Total antibiotics consumption (DDDs) reduced from 56,725 in 2011 to 31,380 in 2014;antibiotic use density (AUD) reduced from 93.8 to 43.5;mean (± SD) antibiotic costs per patient (per quarter) decreased from 637 (± 29) RMB to 462 (± 49) RMB;and the mean total drug consumption (g)/DDD (DDDs) for inpatients decreased from 90.4 (± 3.3) to 56.4 (± 9.5). Multidrug-resistant microorganisms isolation reduced signifi cantly from 463 (20.0) to 216 (6.9%). Resistance rate of general spectrum antibiotics reduced remarkably after intervention. The proportion of patients colonized or infected with Carbapenems-resistantAcinetobacter baumannii was correlated with DDDs of carbapenem. Conclusions Implementation of ASP leads to reduced medical expense, decrease of improper and abuse of antibiotics, and reduced antibiotics resistance rate and MDRO isolation. Continuous eff orts to improve antibiotic use are required.展开更多

While most people came to see the shorebird and horseshoe crab spectacle (60%), many came for the scenery, tranquility, and recreation. Just over half of the people interviewed said that the stewards were helpful (58%), although most of those that answered this question later said that they provided conservation value (86%), but only 40% said they relied on the stewards for information. On a Likert rating scale of 1 to 5 (the highest value), the mean rating for whether it was important for stewards to be present was 3.87 ± 0.09, and the rating for the presence of stewards who can provide information was 3.71 ± 0.11. In contrast, protection of shorebirds was rated a mean of 4.79 ± 0.04. There were significant visitor type differences in how important stewards were, but not in the importance of stewards who can provide information. Fishermen, recreationists, and people coming for scenery and tranquility rated the presence of stewards higher than those visitors who were interested in either shorebirds or crabs (or both). Ratings also differed significantly as a function of age and gender;older adults and females rated characteristics higher than did people under 30 years and males. Information needs identified by stewards are also discussed. These data can be used by the managers developing a strategy for conservation of shorebirds and other species sensitive to disturbance, and for the implementation of an effective stewardship program.
文摘How govemment think about regulation in the 21st century is changing. This workshop as the first session of Pacific Area Standards Congress 2019 will bring together standardizers and regulators to Look at how standards can play a part in regulatory stewardship, an innovative and proactive approach for government regulatory agencies.

文摘Objective To evaluate the effect of pharmacist-driven antimicrobial stewardship based on value-based healthcare in a tertiary hospital in China.Methods The application of plan-do-check-action(PDCA)cycle and antimicrobial stewardship(AMS)were respectively used to improve the rational use of antimicrobial agents in prophylactic and therapeutic.Data were collected and the effect was assessed during the management period(2016-2019).Results and Conclusion From 2016(before implementation)to 2019(after implementation),the rational use of antibiotics were obviously enhanced in outpatients,inpatients,and emergency department.For instance,the utilization rate in type I incision operation was decreased from 26.42%to 14.60%(P=0.000),the daily doses of antibiotic per 100 patient-days decreased from 49.34±2.97 to 35.89±4.96(P=0.000),and the average antibiotic expenditures dropped from 948.53 yuan to 526.30 yuan(P=0.000).There was no significant change in infection rate,nosocomial mortality rate,and the length of hospital stay.After the implementation of clinical pharmacist-driven antimicrobial stewardship based on value-based healthcare,the consumption and cost of antibacterial have been greatly reduced.Therefore,the pharmacist-driven antimicrobial stewardship increases its value。
文摘Pregnant and postnatal women are a high-risk population particularly prone to rapid progression to sepsis with significant morbidity and mortality worldwide.Moreover,severe maternal infections can have a serious detrimental impact on neonates with almost 1 million neonatal deaths annually attributed to maternal infection or sepsis.In this review we discuss the susceptibility of pregnant women and their specific physiological and immunological adaptations that contribute to their vulnerability to sepsis,the implications for the neonate,as well as the issues with antimicrobial stewardship and the challenges this poses when attempting to reach a balance between clinical care and urgent treatment.Finally,we review advancements in the development of pregnancy-specific diagnostic and therapeutic approaches and how these can be used to optimize the care of pregnant women and neonates.
文摘High resistance rates to antimicrobials continue to be a global health threat.The incidence of multidrug-resistant(MDR)microorganisms in intensive care units(ICUs)is quite high compared to in the community and other unitsin the hospital because ICU patients are generally older,have higher numbers of co-morbidities and immunesuppressed;moreover,the typically high rates of invasive procedures performed in the ICU increase the risk ofinfection by MDR microorganisms.Antimicrobial stewardship(AMS)refers to the implementation of coordinatedinterventions to improve and track the appropriate use of antibiotics while offering the best possible antibioticprescription(according to dose,duration,and route of administration).Broad-spectrum antibiotics are frequentlypreferred in ICUs because of greater infection severity and colonization and infection by MDR microorganisms.For this reason,a number of studies on AMS in ICUs have increased in recent years.Reducing the use of broadspectrum antibiotics forms the basis of AMS.For this purpose,parameters such as establishing an AMS team,limiting the use of broad-spectrum antimicrobials,terminating treatments early,using early warning systems,pursuing infection control,and providing education and feedback are used.In this review,current AMS practicesin ICUs are discussed.
文摘Background This study aimed to investigate the eff ect of antibiotic stewardship programs (ASP) on reducing antimicrobial resistance rate, antibiotics consumption and multi-drug resistance bacterial infections in the pediatric patients. Methods This study was carried out in the Pediatric Center of a tertiary hospital of Shandong Province, China. The study duration was separated into two periods according to introduction of ASP (began from April 2011). Before intervention: from April 2009 to March 2011;after intervention: from April 2012 to March 2014. The consumption of antibiotics, defi ned daily dose (DDD), isolation of multidrug-resistant organisms (MDRO) and resistance rate of antibiotics were analyzed and compared between the two study periods. Results Total antibiotics consumption (DDDs) reduced from 56,725 in 2011 to 31,380 in 2014;antibiotic use density (AUD) reduced from 93.8 to 43.5;mean (± SD) antibiotic costs per patient (per quarter) decreased from 637 (± 29) RMB to 462 (± 49) RMB;and the mean total drug consumption (g)/DDD (DDDs) for inpatients decreased from 90.4 (± 3.3) to 56.4 (± 9.5). Multidrug-resistant microorganisms isolation reduced signifi cantly from 463 (20.0) to 216 (6.9%). Resistance rate of general spectrum antibiotics reduced remarkably after intervention. The proportion of patients colonized or infected with Carbapenems-resistantAcinetobacter baumannii was correlated with DDDs of carbapenem. Conclusions Implementation of ASP leads to reduced medical expense, decrease of improper and abuse of antibiotics, and reduced antibiotics resistance rate and MDRO isolation. Continuous eff orts to improve antibiotic use are required.
文摘A growing number of research funding organizations(RFOs)are taking responsibility to increase the scientific and social impact of research output.Also reusable research data are recognized as relevant output for gaining impact.RFOs are therefore promoting FAIR research data management and stewardship(RDM)in their research funding cycle.However,the implementation of FAIR RDM still faces important obstacles and challenges.To solve these,stakeholders work together to develop innovative tools and practices.Here we elaborate on the role of RFOs in developing a FAIR funding model to support the FAIR RDM in the funding cycle,integrated with research community specific guidance,criteria and metadata,and enabling automatic assessments of progress and output from RDM.The model facilitates to create research data with a high level of FAIRness that are meaningful for a research community.To fully benefit from the model,RFOs,research institutions and service providers need to implement machine actionability in their FAIR RDM tools and procedures.As many stakeholders still need to get familiar with“human actionable”FAIR data practices,the introduction of the model will be stepwise,with an active role of the RFOs in driving FAIR RDM processes as effectively as possible.

文摘The emergence of the Anthropocene creates a new set of conditions for understanding the relationship between human power and the natural world.These conditions include an increasingly humanized and de-natured natural world,and greater responsibilities of stewardship for human beings.In current literature,there are diverse views on the meaning of the Anthropocene and the role of modem technology in future earth stewardship.Post-natural thought regards the Anthropocene as representing the end of nature,and thus appeals to disenchantment with respect to the idea that nature is an external moral norm.Although this approach correctly addresses the significance of locality and the mutuality between humans and the environment,it fails to provide us with adequate normative boundaries for preventing the endless artificialization of nature.Alternatively,this article defends the position that Confucianism is a more plausible philosophical ground for earth stewardship in the context of the Anthropocene.The Confucian approach is an inclusive humanism which is established on the cosmological ideal of realising the virtue of shengsheng生生(life generation)in all beings.Moreover,Confucian ethics draw much attention to the self-regulation of human beings as virtuous persons.This is indeed what is needed in the age of the Anthropocene.
