Abstract
Background Antimicrobial consumption continues to rise globally and contributes to the emergence and spread of antimicrobial resistance. This study aimed to evaluate antimicrobial prescribing patterns in a selected tertiary hospital in Tanzania. Methods This cross-sectional study was conducted for one year (September 2021-September 2022) at Mbeya Zonal Referral Hospital, a public hospital in the southern highlands zone of Tanzania. Data on clinical diagnosis, laboratory tests, prescribed antimicrobials, and prescribers' designations were collected through a custom eMedical system, aligning antimicrobials with the WHO's 2021 AWaRe classification. Descriptive analysis was performed to assess the pattern of antimicrobial prescriptions. Results Of 2,293 antimicrobial prescriptions, 62.41% were ACCESS, 37.42% were WATCH, and 0.17% fell in the RESERVE categories. Metronidazole, accounting for 23.8%, was the most commonly prescribed antimicrobial. More than 50% of the ACCESS and WATCH prescriptions were justified by laboratory diagnosis and were predominantly prescribed by clinicians. A very small proportion of prescriptions (<1%) were informed by culture and sensitivity (C/S) testing. The Paediatric department had the majority of WATCH prescriptions (72.2%). Conclusion The prescribing patterns at the study hospital generally align with WHO AWaRe guidelines, potentially mitigating antimicrobial resistance. Nevertheless, the scarcity of culture and sensitivity testing is a concern that warrants targeted improvement.

Abstract
Drug resistance in microorganisms is a serious threat to life and health due to the limited number of antibiotics that show efficacy in treating infections and the difficulty in discovering new compounds with antibacterial activity. To address this issue, the World Health Organization created the AWaRe classification, a tool to support global and national antimicrobial stewardship programs. The AWaRe list categorizes antimicrobials into three groups - Access, Watch, and Reserve - according to their intended use. The Reserve group comprises "last resort" medicines used solely for treating infections caused by bacterial strains that are resistant to other treatments. It is therefore necessary to protect them, not only by using them as prudently as possible in humans and animals, but also by monitoring their subsequent fate. Unmetabolized antibiotics enter the environment through hospital and municipal wastewater or from manure, subsequently contaminating bodies of water and soils, thus contributing to the emergence and spread of antibiotic resistance. This article presents a review of determination methods for the Reserve group of antimicrobials in water, wastewater, and manure. Procedures for extracting and determining these substances in environmental samples are described, showing the limited research available, which is typically on a local level.

Abstract
BACKGROUND Exposure to antibiotics has been shown to be one of the drivers of antimicrobial resistance (AMR) and is critical to address when planning and implementing strategies for combatting AMR. However, data on antibiotic use in sub-Saharan Africa are still limited. Using hospital-based surveillance data from the African Network for Improved Diagnostics, Epidemiology and Management of Common Infectious Agents (ANDEMIA), we assessed self-reported antibiotic use in multiple sub-Saharan African countries. METHODS ANDEMIA included 12 urban and rural health facilities in Côte d'Ivoire, Burkina Faso, Democratic Republic of the Congo, and Republic of South Africa. Patients with acute respiratory infection (RTI), acute gastrointestinal infection (GI) and acute febrile disease of unknown cause (AFDUC) were routinely enrolled, and clinical, demographic, socio-economic and behavioral data were collected using standardized questionnaires. An analysis of ANDEMIA data from February 2018 to May 2022 was conducted. Reported antibiotic use in the ten days prior to study enrolment were described by substance and by the WHO AWaRe classification ("Access", "Watch", "Reserve", and "Not recommended" antibiotics). Frequency of antibiotic use was stratified by location, disease syndrome and individual patient factors. RESULTS Among 19,700 ANDEMIA patients, 7,258 (36.8%) reported antibiotic use. A total of 9,695 antibiotics were reported, including 54.7% (n = 5,299) from the WHO Access antibiotic group and 44.7% (n = 4,330) from the WHO Watch antibiotic group. The Watch antibiotic ceftriaxone was the most commonly reported antibiotic (n = 3,071, 31.7%). Watch antibiotic use ranged from 17.4% (56/322) among RTI patients in Côte d'Ivoire urban facilities to 73.7% (630/855) among AFDUC patients in Burkina Faso urban facilities. Reported antibiotic use included WHO Not recommended antibiotics but no Reserve antibiotics. CONCLUSIONS Reported antibiotic use data from this multicenter study in sub-Saharan Africa revealed a high proportion of WHO Watch antibiotics. Differences in Watch antibiotic use were found by disease syndrome, country and health facility location, which calls for a more differentiated approach to antibiotic use interventions including further evaluation of accessibility and affordability of patient treatment.

Abstract
BACKGROUND The AWaRe tool was set up by the World Health Organization (WHO) to promote the rational use of antimicrobials. Indeed, this tool classifies antibiotics into four groups: access, watch, reserve and not-recommended antibiotics. In The Democratic Republic of Congo, data on antibiotic dispensing (prescribing) by health professionals according to the AWaRe classification are scarce. In this research work, we aimed to explore antibiotic dispensing pattern from health professionals according to the WHO AWaRe classification to strengthen the national antimicrobial resistance plan. METHODS For this purpose, a survey was conducted from July to December 2022 in the district of Tshangu in Kinshasa. From randomly selected drugstores, drug-sellers were interviewed and randomly selected customers attending those drugstores were included in the study for medical prescriptions collection. The prescribed antibiotics were classified into the access, watch, reserve and not-recommended antibiotics group and by antibiotics number by prescription among pharmacies surveyed. RESULTS 400 medical prescriptions were collected from 80 drugstores and among which, 301 (75.25%) contained antibiotics. Out of 301 prescriptions, we noticed 164 (54.5%) containing one antibiotic, 117 (38.9%) containing two antibiotics, 15 (5%) containing three antibiotics and 5 (1.6%) containing four antibiotics. A total of 463 antibiotics were prescribed and distributed as 169 (36.5%) were from the access group, 200 (43.2%) from the watch group and 94 (20.3%) from not-recommended antibiotics group, respectively. This can explain the fact of emerging bacterial strains, as, according to the WHO recommendations, the access group should be prioritized because of its activity against a wide range of commonly encountered pathogens and its showing low resistance susceptibility compared to antibiotics from other groups. Based on the anatomical, therapeutic and chemical (ATC) classifications, we observed that third generation cephalosporins represented 34.33% of the prescribed antibiotics, followed by penicillins (17.17%), macrolides (7.63%), aminoglycosides (7.36%) and Imidazole (7.36%), thus accounting approximately for 74% of the classes of antibiotics prescribed. Additionally, among them, the most frequently prescribed antibiotics were Ceftriaxone (21.38%), Amoxicillin (11.01%), Gentamycin (5.61%), Amoxicillin-clavulanic acid (5.61%), Azithromycin (4.97%) and Metronidazole (4.75%), thus accounting for approximately 54% of all the prescribed antibiotics. CONCLUSION These results highlight the importance of strict implementation of the national plan to combat antimicrobial resistance and the need to train health workers in the correct application of the WHO AWaRe classification.

Abstract
BACKGROUND Fixed-dose combinations (FDC) are medicine formulations that combine two or more ingredients in fixed ratios in a single dose form. Although advantageous in tuberculosis and malaria (efficacy, adherence, protection against resistance), only a few antibiotic FDC (FDC-AB) have been developed along full microbiological, pharmacological and clinical validation and safety studies. The World Health Organization (WHO) database of Access, Watch and Reserve (AWaRe) antibiotics contains, since 2021, a list of "Not Recommended" FDC-AB (n = 103) which are rejected for use in clinical practice. BODY: The share of non-recommended FDC-AB in global antimicrobial use (2000-2015) was < 3% but substantially higher in middle income countries. The share increases over time, but recent data particular concerning sub-Saharan Africa are rare. Along three non-recommended FDC-AB listed in the Tanzanian National Essential Medicine List (ampicillin-cloxacillin, flucloxacillin-amoxicillin and ceftriaxone-sulbactam) we discuss the concerns and reasons behind use of these products. Non-recommended FDC-AB have poor rationale (ratios of both ingredients), lack evidence of efficacy (pharmacological, microbiological and clinical), have difficulties in dosing (underdosing of the single ingredients, absence of pediatric dosing) and risks of safety (additive toxicity). They are expected to fuel antimicrobial resistance (unnecessary broad spectrum coverage) and are incompatible with antimicrobial stewardship. The specific context of low- and middle-income countries contributes to their increased use: at the side of prescriber and supplier are the lack of diagnostics, poor training in antibiotic prescribing, patients' preferences, role-model of senior prescribers and pharmaceutical promotion. International market mechanisms include economic motivation for development, branding and promotion, poor access to the single antibiotic forms and weak national regulatory capacity. CONCLUSION AND IMPLICATIONS There is an urgent need for monitoring consumption of non-recommended FDC-AB in low- and middle-income countries, particular in Sub-Saharan Africa. A multinational and multisectoral antimicrobial stewardship strategy is needed in order to abolish the use of non-recommended FDC-AB.
