Mapping the Antimicrobial Supply Chain in Bangladesh: A Scoping-Review-Based Ecological Assessment Approach.

Maintaining access to antimicrobials while preventing misuse is essential to combating the threat of antimicrobial resistance (AMR). The study objectives are to propose a framework of 16 indicators that can be used at the national level to assess the capacity to ensure access and curtail inappropriate use and to profile the antimicrobial supply chain for Bangladesh. Using a framework based on a rational construct, we assessed the antimicrobial supply chain of Bangladesh, with a focus on key players and products using a scoping review to obtain and describe information on 16 indicators. With players, we mapped linkages, manufacturers' production capacity, and ownership, among others, and demand point characteristics-pharmacy and pharmacist density, pharmacy/medicine outlets dispersion, veterinary clinic/hospitals, veterinarians' density, product quality, and regulation. We assessed product characteristics including listing on the World Health Organization (WHO) Model Essential Medicines List (EML) and WHO Access, Watch, and Reserve (AWaRe) classification of the major (top 10) antibiotics for human use; the proportion of medically important antimicrobials (MIAs) in veterinary use; and pricing. Production capacity and price controls were used to assess access and listing on the WHO EML, AWaRe/MIA classification, and a calculated pharmacy-to-pharmacist ratio to assess use. Bangladesh has a high (98%) local antibiotic production capacity with pricing controls indicating the ability to ensure access. The presence of a high proportion of medicine outlets not under the control of pharmacists (4:1) and the high percentages of WHO Watch (54%) and MIAs (90%) of the major antibiotics are indicators of possible misuse. Most of the data used in the framework were publicly available. Bangladesh has the capacity to ensure access but needs to strengthen its ability to regulate the quality of antimicrobials and prevent their inappropriate use through antimicrobial stewardship at the community (medicine outlet) levels to check AMR. There may also be a need for more regulations on licensing of MIAs.

Hospital Antibiotic Prescribing Pattern in General Surgery Specialty: Analysis Based on the WHO Access, Watch and Reserve (AWaRe) Classification

Background: Surgical site infections are a prevalent cause of nosocomial infections that require antibiotic prophylaxis. Emergence and spread of antimicrobial resistance is a major global public health issue that must be addressed. Eventually, antibiotic prescribing pattern should be examined in order to ensure that antibiotics are used appropriately and that their effectiveness is preserved.
 Objective: To evaluate hospital antibiotic prescribing pattern emphasizing on cephalosporins in general surgery specialty using the WHO Access, Watch, and Reserve (AWaRe) classification.
 Methodology: A cross-sectional study was carried out in 658 hospitalized patients who received prophylactic antibiotics in general surgery specialty for six months. The data were analysed using the ‘WHO prescribing indicators’ and examined for the WHO ‘AWaRe’ categories. The acquired data was subjected to descriptive statistics.
 Results: Per encounter, the average number of drugs and antibiotics prescribed were 3.8 and 1.3, respectively. 83.4% encounters were with at least one antibiotic and 94.5% encounters had parenteral antibiotics. 31.3% and 77.8% antibiotics were prescribed by generic name and from the Essential Medicines List, respectively. The most frequently prescribed antibiotics were the third generation cephalosporins (36.8%) wherein ceftriaxone (22.0%) and cefoperazone (7.2%) were the two most commonly prescribed. A total of 14 specific antibiotics, ‘Access’ 5 and ‘Watch’ 9 were prescribed. Based on the WHO AWaRe classification, 42.3% ‘Access’ and 57.7% ‘Watch’ group antibiotics prescribed. All the prescribed cephalosporins (100%) were from the ‘Watch’ category. Amikacin (13.5%) and ceftriaxone (22.0%) were the most commonly prescribed ‘Access’ and ‘Watch’ group antibiotics, respectively. Amoxicillin index was 7.5 and ‘Access-to-Watch’ index was 0.7, which were much below the priority values.
 Conclusion: The antibiotic prescription pattern seen in this study did not entirely meet the WHO recommendations. Antibiotics from the ‘Watch’ category, notably cephalosporins, were commonly prescribed. To retain antibiotic effectiveness and encourage rational antibiotic use, as well as to overcome antibiotic resistance, changes and surveillance antibiotics prescribing are required.

P–679 Magnetic resonance imaging (MRI), an alternative method to evaluate the ovarian reserve

Abstract Study question Is magnetic resonance imaging (MRI) a valid method to access antral follicles count (AFC) compared to two-dimensional (2D) transvaginal ultrasonography (USG) and Anti-Mullerian Hormone (AMH) to evaluate the ovarian reserve? Summary answer AFC has a high agreement between MRI and USG methods, as well as with AMH. MRI can be an alternative method to evaluate ovarian reserve. What is known already In fact, two methods are the most used today to assess ovarian reserve: USG and AMH. The USG is considered the gold standard method for AFC, and contributes to predict and tailor treatment strategies, such as in-vitro fertilization. The major limitations of USG are its user dependency and equipment. Also, there are limitations in displaying a global view of the pelvis and large ovarian lesions. Magnetic resonance imaging (MRI), with its excellent soft-tissue contrast resolution and characteristics, is a useful non-invasive alternative modality to USG. Just one study evaluated MRI and revealed more small size antral follicles compared to 3D-USG. Study design, size, duration A prospective cross-sectional observational study was performed in an assisted reproduction techniques (ART) post-graduation program setting from an assisted reproductive center in Sao Paulo, Brazil, which ran throughout 2019–2020, with a total number of 59 patients that were in fertility treatment and needed to undergo to a MRI procedure to evaluate uterine or pelvic diseases as, Myoma, Adenomyosis, endometriosis, and adnexal cysts. Participants/materials, setting, methods Patients were evaluated to access the AFC by the MRI method and 2D transvaginal USG, and Anti-Mullerian Hormone (AMH) concentration to evaluate the ovarian reserve. Comparison between methods was done through Wilcoxon signed ranks test and Bland-Altman analysis. Ovarian reserve was classified as follows: very low (<4 follicles/AMH<0.5); low (5–7 follicles/AMH=0.5–1.1); normal (8–15 follicles/AMH=1.1–3.5); normal-high (>15 follicles/AMH>3.5). Weighted Cohen’s kappa was used to verify agreement between MRI, USG and AMH classifications of ovarian reserve. Main results and the role of chance Average AFC for USG were 5,55±4.01 for left ovary and 5.55±3.8 for right ovary. Average follicle count for both ovaries was 10±7.07. Regarding MRI, mean counts were 6.44±4.81 for left ovary, 5.65±3.85 for right ovary, and a 11.89±7.89 follicle sum mean count. Average concentration of AMH was 1.79±1.44. The Wilcoxon test and Bland-Altman analyses found differences and systematic biases for comparison between USG and MRI for both ovaries (–2.58; limits of agreement=–14.56 to 9.40, Wilcoxon p = 0,008) and for the right ovary (–1.48; limits of agreement=–8.32 to 5.35, Wilcoxon p = 0,031). There was no difference between methods for the left ovary. Weighted Cohen Kappa coefficients showed substantial agreement between ovarian reserve classifications based on AMH levels, USG, and MRI. The conducted paired comparisons were USG with MRI (k = 0.676), AMH with MRI (k = 0.760) and USG (k = 0.609). Limitations, reasons for caution The systematic biases found when comparing USG to MRI methods may suggest a consistent detection of more follicles with MRI procedures in comparison to the USG method. This bias found warrants caution as it must be confirmed, in future studies. Wider implications of the findings: The MRI method reveals similar ovarian reserve to USG when used the same classification, and a higher agreement to AMH. This suggests that MRI is a reliable method of quantifying antral follicles and can also be adopted when the patient will need to evaluate pelvic pathologies.

Progress towards antibiotic use targets in eight high-income countries.

ObjectiveTo compare antibiotic sales in eight high-income countries using the 2019 World Health Organization (WHO) Access, Watch and Reserve (AWaRe) classification and the target of 60% consumption of Access category antibiotics.MethodsWe analysed data from a commercial database of sales of systemic antibiotics in France, Germany, Italy, Japan, Spain, Switzerland, United Kingdom of Great Britain and Northern Ireland, and United States of America over the years 2013–2018. We classified antibiotics according to the 2019 AWaRe categories: Access, Watch, Reserve and Not Recommended. We measured antibiotic sales per capita in standard units (SU) per capita and calculated Access group sales as a percentage of total antibiotic sales.FindingsIn 2018, per capita antibiotic sales ranged from 7.4 SU (Switzerland) to 20.0 SU (France); median sales of Access group antibiotics were 10.9 SU per capita (range: 3.5–15.0). Per capita sales declined moderately over 2013–2018. The median percentage of Access group antibiotics was 68% (range: 22–77 %); the Access group proportion increased in most countries between 2013 and 2018. Five countries exceeded the 60% target; two countries narrowly missed it (> 55% in Germany and Italy). Sales of Access antibiotics in Japan were low (22%), driven by relatively high sales of oral cephalosporins and macrolides.ConclusionWe have identified changes to prescribing that could allow countries to achieve the WHO target. The 60% Access group target provides a framework to inform national antibiotic policies and could be complemented by absolute measures and more ambitious values in specific settings.

Comparison of antibiotics included in national essential medicines lists of 138 countries using the WHO Access, Watch, Reserve (AWaRe) classification: a cross-sectional study

The WHO Model List of Essential Medicines classified antibiotics into Access, Watch, and Reserve (AWaRe) categories for the treatment of 31 priority bacterial infections as a tool to facilitate antibiotic stewardship and optimal use. We compared the listing of antibiotics on national essential medicines lists (NEMLs) to those in the 2019 WHO Model List and the AWaRe classification database to determine the degree to which NEMLs are in alignment with the AWaRe classification framework recommended by WHO. In this cross-sectional study, we obtained up-to-date (data after 2017) NEMLs from our Global Essential Medicines (GEM) database, WHO online resources, and individual countries' websites. From the 2019 WHO Model List we extracted, as a reference standard, a list of 37 antibiotics (44 unique antibiotics after accounting for combination drugs or therapeutically equivalent drugs as specified by WHO) that were considered essential in treating 31 of the most common and severe clinical infectious syndromes (priority infections). From the WHO AWaRe Classification Database, which contains commonly used antibiotics globally, we extracted a list of 122 AWaRe antibiotics listed by at least one country in the GEM database. We then assessed individual countries' NEMLs for listing of the 44 essential and 122 commonly used antibiotics, overall and according to AWaRe classification group. We also evaluated and summarised the listing of both first-choice and second-choice treatments for the 31 priority infections. A total coverage score was calculated for each country by assigning a treatment score of 0-3 for each priority infection on the basis of whether first-choice and second-choice treatments, according to the 2019 WHO Model List, were included in the country's NEML. Coverage scores were then compared against the score of the 2019 WHO Model List and across World Bank income groups and WHO regions. As of July 7, 2020, we had up-to-date NEMLs for 138 countries. Of the 44 unique essential antibiotics, 24 were Access, 15 were Watch, and five were Reserve. The median number of total essential antibiotics listed across the 138 NEMLs was 26 (IQR 21-32). 102 (74%) countries listed at least 22 (50%) of the 44 essential antibiotics. The median number of total AWaRe antibiotics listed by the 138 countries was 35 (IQR 29-46), of Access antibiotics was 18 (16-21), of Watch antibiotics was 16 (11-22), and of Reserve antibiotics was one (0-2). 56 (41%) countries did not list any essential Reserve antibiotics. 131 (95%) countries had coverage scores of at least 60, equivalent to at least 75% of the score of the 2019 WHO Model List, which was 80. Nine (7%) countries listed fewer than 12 of 24 essential Access antibiotics, and seven (5%) did not list sufficient first-choice and second-choice treatments for priority infections (ie, they had coverage scores lower than 60). Of the 31 priority infections, acute neonatal meningitis and high-risk febrile neutropenia did not have enough listed treatments, with 82 (59%) countries listing no treatment for acute neonatal meningitis and 84 (61%) countries listing only a first-choice treatment, only a second-choice treatment, or no treatment for high-risk febrile neutropenia. Coverage scores differed between countries on the basis of World Bank income groups (p=0·025). Our findings highlight potential changes to the antibiotics included in NEMLs that would increase adherence to international guidance aimed at effectively treating infectious diseases while addressing antimicrobial resistance.

Antibiotic Prescribing Practices in Primary Care Settings Using 2019 WHO AWaRe Framework

Background: Bacteria have ability to rapidly evolve, develop strategies to resist antibiotics, and reduce the effectiveness of antibiotics. The emergence and spread of antimicrobial resistance is an important global public health challenge to tackle. Studying antibiotic prescribing practices would allow rational use and preserve effectiveness of antibiotics.
 Objective: To study prescribing practices of antibiotics in out-patients in primary care settings using the WHO AWaRe framework.
 Methodology: A prospective cross-sectional study was conducted to evaluate prescribing practices of antibiotics in the primary care facility of three private hospitals using the WHO ‘core prescribing indicators’ and Access, Watch, and Reserve (AWaRe) classification. A systematic sampling technique was employed to collect the prescriptions at each hospital for three months. Descriptive statistics were applied to the collected data.
 Results: A total of 2685 prescriptions were systematically evaluated. 1280 encounters had at least one antibiotic (47.7%), of which 1041 consist of only one antibiotic (81.5%). Among 1280 antibiotic encounters, the average number of antibiotics per encounter was 1.2 and 14.6% were prescribed with a parenteral antibiotic. 26.6% and 78.6% antibiotics were prescribed using generic names and from the WHO Essential Medicines List, respectively. Amoxicillin/clavulanic acid, ceftriaxone, azithromycin, cefoperazone, and amoxicillin were the five most commonly prescribed antibiotics. According to the WHO AWaRe classification, a total of 27 specific antibiotics (Access 11, Watch 14, and Reserve 2) were prescribed. 38.4%, 53.7%, 0.3%, and 10.5% of antibiotics prescribed were from the ‘Access’, ‘Watch’, ‘Reserve’, and ‘Not Recommended’ categories, respectively. Third generation cephalosporins (24.0%) were prescribed in high rate among ‘Watch’ category. The most commonly prescribed ‘Access’ and ‘Watch’ antibiotics were amoxicillin/clavulanic acid (12.5%) and ceftriaxone (10.6%), respectively. Amoxicillin index was 19.5% and ‘Access-to-Watch’ index was 0.76, which were below the priority values.
 Conclusion: Except few indicators, still better prescribing practices of antibiotics are needed to fully meet the WHO recommendations. Antibiotic prescribing guidelines as per the WHO AWaRe framework, changes in prescription patterns and preference of “Access” over ‘Watch’ antibiotics are crucial to preserve effectiveness and promote rational use of antibiotics.

Classification of residual oil reserves and methods of its recovery

Many oil and gas fields are currently at a late stage of development, while most of them are being developed using flooding. These fields are characterized by the decreasing oil and liquid flow rates and accelerating water-cut. During the development process, the majority of oil reserves are extracted not using methods of production enhancement. Though, oil reserves within undeveloped areas are a valuable source for recovery. To involve residual reserves in active development, it is necessary to make a reasonable justification and a choice of the most effective geological and technical measures that take into account various geological field and well reservoir characteristics. Residual oil reserves at the late stage of development are classified as hard-to-recover and are mainly concentrated in areas not covered by flooding laterally and vertically. They belong to various categories that differ in the geological and technological characteristics. In this regard, it is necessary to plan various geological and technical measures taking into account the structure of residual reserves and patterns of their distribution. Studies of complex oil and gas fields were performed and a detailed analysis of the geological and physical characteristics, parameters of reservoir heterogeneity along with operational, geological and commercial assessment of reserves development were conducted.

Evaluation of Prescribing Patterns of Antibiotics Using Selected Indicators for Antimicrobial Use in Hospitals and the Access, Watch, Reserve (AWaRe) Classification by the World Health Organization

Antibiotic resistance poses a significant threat to the world, and irrational use of antibiotics is a major contributing factor. Evaluation of antimicrobial use is underway with the help of indicators and the World Health Organization (WHO) classification of antibiotics into Access, Watch, and Reserve (AWaRe) categories. We aimed to evaluate the prescribing pattern of antibiotics using the AWaRe classification by the WHO and selected indicators for antimicrobial use in hospitals. A total of 1.000 prescriptions were analyzed during the study for antibiotic prescribing patterns. Antibiotic consumption was calculated using defined daily dose (DDD) methodology. The prescribing pattern was evaluated using the WHO classification of antibiotics into the categories AWaRe and using selected indicators (hospital and prescribing) for antimicrobial use in hospitals. A total of 1.128 antibiotics were prescribed during the study. The 19-44 age group was prescribed a high number of antibiotics (n=510). Females were prescribed a high number of antibiotics compared with males (n=602). Azithromycin was the most commonly consumed antibiotic (14.97 DDD/1000/day). Four antibiotics from the Access category and five from the Watch category were prescribed in the study. The Watch category of antibiotics were consumed in a high number. There were no standard treatment guidelines in the hospital. In all, 98.0% of antibiotics were consistent with the hospital formulary and prescribed under generic names. The average number of antibiotics prescribed per patient was 1.12. The average duration of antimicrobial treatment was 5.24 days. The percentage of patients prescribed antimicrobials for pneumonia in accordance with treatment guidelines was 13.28%. Irrational use of antibiotics exists in hospitals. There is a need to maintain standard treatment guidelines in the hospital because it prevents irrational use of antibiotics.

Variations in the Consumption of Antimicrobial Medicines in the European Region, 2014-2018: Findings and Implications from ESAC-Net and WHO Europe.

Background: Surveillance of antimicrobial consumption (AMC) is important to address inappropriate use. AMC data for countries in the European Union (EU) and European Economic Area (EEA) and Eastern European and Central Asian countries were compared to provide future guidance. Methods: Analyses of 2014–2018 data from 30 EU/EEA countries of the European Surveillance of Antibiotic Consumption network (ESAC-Net) and 15 countries of the WHO Regional Office for Europe (WHO Europe) AMC Network were conducted using the Anatomical Therapeutic Chemical (ATC) classification and Defined Daily Dose (DDD) methodology. Total consumption (DDD per 1000 inhabitants per day) of antibacterials for systemic use (ATC group J01), relative use (percentages), trends over time, alignment with the WHO Access, Watch, Reserve (AWaRe) classification, concordance with the WHO global indicator (60% of total consumption should be Access agents), and composition of the drug utilization 75% (DU75%) were calculated. Findings: In 2018, total consumption of antibacterials for systemic use (ATC J01) ranged from 8.9 to 34.1 DDD per 1000 inhabitants per day (population-weighted mean for ESAC-Net 20.0, WHO Europe AMC Network 19.6, ESAC-Net Study Group, and WHO Europe AMC Network Study Group). ESAC-Net countries consumed more penicillins (J01C; 8.7 versus 6.3 DDD per 1000 inhabitants per day), more tetracyclines (J01A; 2.2 versus 1.2), less cephalosporins (J01D; 2.3 versus 3.8) and less quinolones (J01M; 1.7 versus 3.4) than WHO Europe AMC Network countries. Between 2014 and 2018, there were statistically significant reductions in total consumption in eight ESAC-Net countries. In 2018, the relative population-weighted mean consumption of Access agents was 57.9% for ESAC-Net and 47.4% for the WHO Europe AMC Network. For each year during 2014–2018, 14 ESAC-Net and one WHO Europe AMC Network countries met the WHO global monitoring target of 60% of total consumption being Access agents. DU75% analyses showed differences in the choices of agents in the two networks. Interpretation: Although total consumption of antibacterials for systemic use was similar in the two networks, the composition of agents varied substantially. The greater consumption of Watch group agents in WHO Europe AMC Network countries suggests opportunities for improved prescribing. Significant decreases in consumption in several ESAC-Net countries illustrate the value of sustained actions to address antimicrobial resistance.

An Assessment of the Impact of Coronavirus Disease (COVID-19) Pandemic on National Antimicrobial Consumption in Jordan.

Coronavirus disease 2019 (COVID-19) has overlapping clinical characteristics with bacterial respiratory tract infection, leading to the prescription of potentially unnecessary antibiotics. This study aimed at measuring changes and patterns of national antimicrobial use for one year preceding and one year during the COVID-19 pandemic. Annual national antimicrobial consumption for 2019 and 2020 was obtained from the Jordan Food and Drug Administration (JFDA) following the WHO surveillance methods. The WHO Access, Watch, and Reserve (AWaRe) classification was used. Total antibiotic consumption in 2020 (26.8 DDD per 1000 inhabitants per day) decreased by 5.5% compared to 2019 (28.4 DDD per 1000 inhabitants per day). There was an increase in the use of several antibiotics during 2020 compared with 2019 (third generation cephalosporins (19%), carbapenems (52%), macrolides (57%), and lincosamides (106%)). In 2020, there was a marked reduction in amoxicillin use (−53%), while the use of azithromycin increased by 74%. National antimicrobial consumption of the Access group decreased by 18% from 2019 to 2020 (59.1% vs. 48.1% of total consumption). The use of the Watch group increased in 2020 by 26%. The study highlighted an increase in the use of certain antibiotics during the pandemic period that are known to be associated with increasing resistance. Efforts to enhance national antimicrobial stewardship are needed to ensure rational use of antimicrobials.

Antibiotic Prescribing Practice in Chronic Kidney Disease Patients in a Tertiary Care Teaching Hospital: Analysis Based on 2019 WHO AWaRe Classification

Chronic kidney disease (CKD) patients are prone to infections and inevitably require antibiotics. Antimicrobial resistance (AMR) is a global threat to humans. Indeed, the most important cause for spread of AMR is irrational use of antibiotics. Therefore, the present study evaluates prescribing practice of antibiotics in CKD patients. A cross-sectional study was carried out in 382 CKD in-patients prescribed with antibiotics. The data were analysed using the WHO prescribing indicators and the WHO Access, Watch, and Reserve (AWaRe) classification. The average number of drugs prescribed per encounter was 3.1. Antibiotics prescribed by generic name and prescribed from the Essential Medicines List were 52.9% and 47.1%, respectively. % Encounters with antibiotics and parenteral antibiotics were 59.2% and 77.4%, respectively. Third generation cephalosporins (76.9%), particularly cefoperazone (40%) and ceftriaxone (21.2%), were the most commonly prescribed antibiotics. A total of 19 specific antibiotics (Access 5, Watch 13, Reserve 1, and Not Recommended 0) were prescribed. According to WHO AWaRe classification, 10.6%, 89%, and 0.4% of antibiotics prescribed were from the ‘Access’, ‘Watch’, ‘Reserve’ categories, respectively. ‘Watch’ category antibiotics, particularly cephalosporins (98%), were prescribed in high rate. The most commonly prescribed ‘Access’ and ‘Watch’ category antibiotics were amikacin (37%) and cefoperazone (44.9%), respectively. Amoxicillin index was 1.6 and ‘Access-to-Watch’ index was 0.1, which were below the priority values. Prescription pattern of antibiotics observed in this study was not fully met the WHO recommendations. Additionally, ‘Watch’ category antibiotics, particularly cephalosporins, were prescribed frequently. Changes in prescription pattern and monitoring of antibiotic use are essential to preserve effectiveness and promote rational use of antibiotics, and to overcome AMR.

Increase and Change in the Pattern of Antibiotic Use in Serbia (2010-2019).

The aim of this study was to determine and describe trends in antibiotics utilization in Serbia over a ten-year period. Data were retrieved from publicly available annual reports (2010–2019). The results were expressed as Defined Daily Dose (DDD) per 1000 inhabitants per day (DID). All calculations were performed using the DDD values for the 2020 Anatomical Therapeutic Chemical/Defined Daily Dose (ATC/DDD) version for each year of the study, to account for the DDD changes during the study period. Antibiotics were classified using the WHO Access, Watch, Reserve (AWaRe) classification. Total utilization of antibacterials for systemic use increased from 17.25 DID in 2010 to 28.65 DID in 2019. A statistically significant increasing trend in the use of the Watch category antibiotics was observed. A tendency towards use of broad-spectrum antibiotics, apparent by a statistically significant increase in the rate of utilization of broad-spectrum macrolides, quinolones and third-generation cephalosporins vs. narrow-spectrum ones, as well as a significant increasing trend in the use of quinolones was identified. Total antibiotic utilization was found to be well above the European average. Several specific problem areas were identified, which requires further efforts to improve antibiotic prescribing. The present study provides the information needed to facilitate antibiotic stewardship in Serbia further and proposes specific interventions to optimize antibiotic use in Serbia.

Hospital antibiotic prescribing patterns in adult patients according to the WHO Access, Watch and Reserve classification (AWaRe): results from a worldwide point prevalence survey in 69 countries

ObjectivesThe WHO Access, Watch and Reserve (AWaRe) classification has been developed to support countries and hospitals in promoting rational use of antibiotics while improving access to these essential medicines. We aimed to describe patterns of worldwide antibiotic use according to the AWaRe classification in the adult inpatient population.MethodsThe Global Point Prevalence Survey on Antimicrobial Consumption and Resistance (Global-PPS) collects hospital antibiotic use data using a standardized PPS methodology. Global-PPS 2015, 2017 and 2018 data, collected by 664 hospitals in 69 countries, were categorized into AWaRe groups to calculate proportional AWaRe use, Access-to-Watch ratios and the most common indications for treatment with selected Watch antibiotics. Only prescriptions for systemic antibiotics on adult inpatient wards were analysed.ResultsRegional Access use ranged from 28.4% in West and Central Asia to 57.7% in Oceania, whereas Watch use was lowest in Oceania (41.3%) and highest in West and Central Asia (66.1%). Reserve use ranged from 0.03% in sub-Saharan Africa to 4.7% in Latin America. There were large differences in AWaRe prescribing at country level. Watch antibiotics were prescribed for a range of very different indications worldwide, both for therapeutic and prophylactic use.ConclusionsWe observed considerable variations in AWaRe prescribing and high use of Watch antibiotics, particularly in lower- and upper-middle-income countries, followed by high-income countries. The WHO AWaRe classification has an instrumental role to play in local and national stewardship activities to assess prescribing patterns and to inform and evaluate stewardship activities.

Introduction of Biological Parameters for Environmentally Sensitive Area (ESA) Classification for Permanent Forest Reserve: A Case Study Based on Small Vertebrates’ Assessments in Selangor

Environmentally sensitive areas (ESAs) is vital for seeking the balance between biodiversity conservation and land use planning based on the concept of sustainable development. However, the classification of ESA in Malaysia grounded on physical attributes and the biological elements neglected. Therefore, the aim of the study is to propose a new approach of ESA for permanent forest reserve classification by integrating biological parameters based on small vertebrates with the existing physical attribute of ESA classification. Three forest reserves in northern Selangor selected and four taxa of small vertebrate e.g. small mammals, birds, amphibians and reptiles assessed to develop the biological parameters. Forty potential biological parameters were listed which were thoroughly screened and examined before final ten parameters were finalised. These parameters were composed of four categories including species diversity, trophic composition, origin of species and conservation status. An initial threshold values for each biological parameter were determined. The finding indicates the parameters are promising and the research need to further fine-tuned by conducting verification tests in various landscapes or regions before being integrated with physical attributes to enhance the existing classification of ESA in Malaysia.

Classification of residual recoverable and non-recoverable oil reserves by the reservoir complexity index (RCI)

The paper considers a new engineering analytical tool for express oil reserves assessment. Proposed method is based on classifying oil reserves by complexity – reservoir complexity index (RCI). It allows to optimize the development system and form a well interventions program.
 The method is suggested to use three main parameters for development complexity estimation: reservoir permeability, start watercut (which contains the parameters of the curve of relative permeability, saturation and viscosity) and geological heterogeneity (pattern efficiency).
 An economic estimation of the well profitability is carried out by calculating PV UDC indicator (unit development cost, CAPEX / total oil production). The advantages of this indicator is that it allows to determine the economic attractiveness and does not require macro parameters and costs for the building well pads
 Due to the economic assessment and well ranking, it is possible to obtain profitable well pads and select candidates for sidetracking.
 The novelty of the work lies in the use of an updated methodology for the reservoir complexity index estimation for the remaining recoverable reserves classification.
 As a result, high-quality tool is created that integrates RCI and economic model. It is aimed for solving reservoir engineering problems and increasing the project cost
 The proposed method can be applied to other fields with minor modifications.

BUSINESS STRUCTURES IN THE AGRO-INDUSTRIAL COMPLEX AS A FACTOR OF INCREASING COMPETITIVENESS

The purpose of the research is to develop theoretical, scientific, methodological and practical provisions for the formation of a production management system of innovative potential based on increasing the competitiveness of the agricultural industry, aimed at ensuring food security in Kazakhstan. Originality of the research. The article shows that the innovative type of economic development requires the development of a competitive innovative potential product, the implementation of the principles of continuous improvement, the search and use of production organization for its effective production. The necessity of forming mechanisms for identifying and using organizational reserves to increase the efficiency of production of innovative potential products is also determined. This opened up the possibility of creating and developing conditions conducive to the mobilization of domestic reserves. Research result. Despite the solution of many theoretical and applied problems reflected in the works of these authors, a General approach to the classification of organizational reserves for improving the efficiency of production of scientific-intensive products is not currently formed, and the issues of forming a mezzanine for identifying and using, and evaluating the level of production efficiency require further improvement.

Formation of an effective policy for the repayment of accounts receivable at the enterprise

Introduction. Trade enterprises in modern conditions have significantly increased the volume of their activities. However, the uncertainty of the external environment and the presence of a number of different problems in the economy as a whole create obstacles to the timely fulfillment of obligations. This necessitates the formation of an effective policy for the repayment of accounts receivable at the enterprise.Objective. The objective of the article is to substantiate the theoretical foundations and develop practical recommendations for the formation of an effective policy for the repayment of receivables at trade enterprises.Methods. To establish the stages of the formation of the policy of repayment of receivables and its constituent elements, analytical empiricism was used with an orientation to the existing initial conditions and foreign experience. The study used the method of assessment and generalization to develop and substantiate proposals aimed at solving the problem of recognizing receivables as uncollectible, as well as to substantiate the approach to the classification of reserves and the calculation of reserves for doubtful debts.Results. A conceptual approach to the formation of an effective policy for the repayment of accounts receivable from trade enterprises has been formed. The study substantiates that the effective development of a trading enterprise is possible due to the combination of such important components of its activities as a good information base of management and an effective policy for repayment of receivables. The result of the study is also the substantiation of the stages of formation of the policy of repayment of receivables, the development of proposals for its assessment and the formation of reserves for doubtful debts.Discussion. A promising area of further research is the development of methods of analysis of receivables by actual indicators, the study of opportunities to improve communication and the formation of information support for trade and technological processes based on the use of modern information systems.

Evaluation of Antibiotic Use in Kazakhstan for the Period 2017-2019 Based on WHO Access, Watch and Reserve Classification (AWaRe 2019).

The purpose of this study is to conduct a comparative analysis of the consumption of antibiotics for systemic use reimbursed by the state in Kazakhstan for 2017–2019 with the Access, Watch, and Reserve classification (AWaRe 2019) of the World Health Organization (WHO). The evaluation of the consumption of antibiotics for systemic use in Kazakhstan for 2017–2019 was carried out using the ATC/DDD methodology in accordance with the WHO AWaRe classification. The study used data on all antibiotics that were centrally purchased by a single purchaser during the study period. To understand how often Access group antibiotics are taken in Kazakhstan, the top-10 most consumed antibiotics were additionally studied. The results of a comparative analysis of the antibiotics for systemic use consumption for 2017–2019 by the Access, Watch, and Reserve groups showed a negative trend of a decrease in the consumption of Access group drugs from 1.17 defined daily dose (DDDs) per 1000 inhabitants per day (DID) (39%) in 2017 to 0.59 DID (30%) in 2019. There is an increase in consumption of Watch group antibiotics from 1.84 DID (61%) in 2017 to 1.37 DID (68%) in 2019, as well as an increase in consumption of Reserve antibiotics from 0.001 DID (0.03%) to 0.4 DID (2.11%). In recent years in Kazakhstan, there has been a decrease in the consumption of Access group antibiotics. In addition, the Watch group antibiotics are widely consumed with a certain upward trend. In 2019, one Reserve antibiotic was included in the top-10 most commonly consumed antibiotics. There is a predominant consumption of parenteral forms of antibiotics for systemic use in the country.

The purpose of this work is formation of a quality control program for geological exploration at the field and geological control of mineral resources evaluation. The study is based on modeling and interpretation of the content of the useful component and the lithology of the field. The contents were assessed by the ordinary kriging method. The substantiation of the upper and lower limits of the con-tent of the useful component is carried out on the basis of laboratory research data using the methods of statistical analysis. Grade estimates were verified by statistical comparison of drilling data with vis-ual grade grades based on modeling data. Relevant factors were taken into account that determine the degree of consistency of geological structures and the category of reserves of the field. The lithologi-cal features that determine the promising zones of mineralization have been established. Implemented data quality check procedures to monitor contamination, reliability and accuracy of analyzes. The pro-cedure for determining the factors that negatively affect the consistency of grades and the parameters of geological characteristics has been implemented. The development and verification of the block model of the field was carried out and the comparison of the volume of the useful component of the block model with the volumes of the formed frames was carried out. As a result of the research car-ried out, the classification of reserves was carried out, taking into account the initial set of available data on the geological structures of the field, analytical sampling data and the content of the useful component.

Optimized allocation method of the VSC-MTDC system for frequency regulation reserves considering the cost

In recent years, the interconnection of asynchronous power grids through the VSC-MTDC system has been proposed and extensively studied in light of the potential benefits of economical bulk power exchanges and frequency regulation reserves sharing. This paper proposed an optimized allocation method for sharing frequency regulation reserves among the interconnected power systems and the corresponding frequency regulation control of the VSC-MTDC system under emergency frequency deviation events. Firstly, the frequency regulation reserve classification is proposed. In the classification, the available frequency response capacity reserves of each interconnection are divided into commercial reserves and regular reserves. While the commercial reserves are procured through long-term contracts, the regular reserves are purchased based on market prices of frequency regulation services. Secondly, based on the proposed frequency regulation reserve classification, a novel frequency regulation control is then introduced for the VSC-MTDC system. This control method could minimize the costs of the disturbed power grid for the needed frequency response supports from the other power grids. Simulation verifications are performed on a modified IEEE 39 bus system and a highly reduced power system model representing the North American grids. The simulation verification indicates that the developed frequency regulation control significantly reduced ancillary service costs of the disturbed power grid.
