Antimicrobial resistance (AMR) is a global concern. Currently, the greatest mortality due to AMR is in Africa. A key driver continues to be high levels of dispensing of antibiotics without a prescription. A need to document current rates of dispensing, their rationale and potential ways forward including antimicrobial stewardship programmes (ASPs). A narrative review was undertaken. The highest rates of antibiotic purchasing were in Eritrea (up to 89.2% of antibiotics dispensed), Ethiopia (up to 87.9%), Nigeria (up to 86.5%), Tanzania (up to 92.3%) and Zambia (up to 100% of pharmacies dispensing without a prescription). However, considerable variation with no dispensing in a minority of countries and situations. Key drivers of self-purchasing included high co-payment levels for physician consultations and antibiotic costs, travel costs, convenience of pharmacies, patient requests, limited knowledge of antibiotics and AMR and weak enforcement. ASPs have been introduced in some African countries along with quality targets to reduce inappropriate dispensing, centering on educating pharmacists and patients. ASP activities need accelerating among community pharmacies alongside quality targets, with greater monitoring of pharmacists' activities to reduce inappropriate dispensing. Such activities, alongside educating patients and HCPs, should enhance appropriate dispensing of antibiotics and reduce AMR.

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

Background/Objectives: Antimicrobial resistance (AMR) is a major global health challenge, particularly in low- and middle-income countries (LMICs). Understanding the knowledge, attitudes, motivations, and expectations of community members regarding antimicrobial use is essential for effective stewardship interventions. This scoping review aimed to identify key themes relating to the critical areas regarding antimicrobial use among community members in primary healthcare (PHC), with a particular focus on LMICs. Methods: OVID Medline, PubMed, and CINAHL databases were searched using Boolean operators and Medical Subject Headings (MeSH) terms relevant to antimicrobial use and community behaviors. The Population, Intervention, Comparison, Outcome, and Study Design (PICOS) framework guided study selection, which focused on community members seeking care in PHC in LMICs. Data management and extraction were facilitated using the Covidence platform, with the Critical Appraisal Skills Programme (CASP) qualitative checklist applied for qualitative studies. A narrative synthesis identified and grouped key themes and sub-themes. Results: The search identified 497 sources, of which 59 met the inclusion criteria, with 75% of the studies conducted in outpatient primary care settings. Four key themes were identified: (1) the ’patient’ theme, highlighting beliefs, knowledge, and expectations, which was the most prominent (40.5%); (2) the ’provider’ theme, emphasizing challenges related to clinical decision-making, knowledge gaps, and adherence to guidelines; (3) the ’healthcare systems’ theme, highlighting resource limitations, lack of infrastructure, and policy constraints; and (4) the ‘intervention/uptake’ theme, emphasizing strategies to improve future antibiotic use and enhance access to and quality of healthcare. Conclusions: Stewardship programs in PHC settings in LMICs should be designed to be context-specific, community-engaged, and accessible to individuals with varying levels of understanding, involving the use of information and health literacy to effectively reduce AMR.

Background: Antimicrobial resistance (AMR) poses a global health threat, particularly in low- and middle-income countries (LMICs) including South Africa where limited resources and knowledge gaps exacerbate inappropriate antimicrobial use. To address this, the community antimicrobial use scale (CAMUS) was developed to assess patients’ knowledge, attitudes and behaviors regarding antimicrobial use in South African primary healthcare (PHC) settings, with the aim of informing antimicrobial stewardship (AMS) strategies.Methods: Development of the CAMUS was informed by a scoping review and theoretical constructs from the Health Belief Model, Social Cognitive Theory, and Theory of Planned Behavior. A pilot study was subsequently conducted in two South African districts, an urban and a rural district, with 30 adult participants to provide insights into patients’ understanding of the items. Data collection involved administering CAMUS alongside a health literacy test followed by cognitive interviews to refine clarity and ensure understanding. A feasibility assessment was also conducted to evaluate the practical use of CAMUS in PHC settings.Results: Participants demonstrated varied knowledge of antimicrobial use. While 60% correctly identified antibiotics as effective for bacterial infections, 93.33% incorrectly believed antibiotics could treat viral illnesses such as colds. Marginal health literacy was prevalent (86.67%). The CAMUS demonstrated feasibility, with an average completion time of 10 minutes. Questions were iteratively revised to improve future clarity and relevance based on the results of the cognitive interviews. Key findings highlighted misconceptions about antibiotics and the influence of social norms and systemic barriers on antimicrobial use behaviors.Conclusion: The CAMUS effectively captures the knowledge, attitudes and behaviors of antimicrobial use in South African PHC settings. Pilot testing demonstrated its feasibility to use it as a tool to assess patient knowledge, attitudes and behaviors related to antimicrobial use in a larger population, to subsequently guide AMS initiatives by addressing knowledge gaps and related barriers to improve future antimicrobial use. Future research will include development of a shorter version of the CAMUS, followed by validation in larger, more diverse populations and in local languages to enhance its usability when investigating antimicrobial use and AMR across LMICs.

Introduction: Inappropriate antibiotic use in (primary healthcare, PHC) settings fuels antimicrobial resistance (AMR), threatens patient safety and burdens healthcare systems. Patients’ knowledge, attitudes, motivations and expectations play a crucial role in antibiotic use behaviour, especially in low-income and middle-income countries including South Africa. There is a need to ensure measures of antibiotic use, interventions and future guidance reflect cultural, community and demographic issues associated with patient views to reduce inappropriate use of antibiotics and associated AMR. The objective of this scoping review is to identify key themes surrounding knowledge, attitudes, motivations and expectations among patients and community members regarding antimicrobial use in PHC settings especially in low-income and middle-income countries. Methods and analysis: This scoping review employs a comprehensive search strategy across multiple electronic databases, including OVID, Medline, PubMed and CINHAL, to identify studies addressing patients or community members seeking care at PHC facilities and exploring key drivers of antimicrobial use. The Covidence web-based platform will be used for literature screening and data extraction and the Critical Appraisal Skills Programme qualitative checklist will assess the quality of qualitative papers. Anticipated results will provide an overview of the current evidence base, enabling identification of knowledge gaps. A narrative synthesis of findings will summarise key themes and patterns in patients’ knowledge, attitudes, motivations and expectations related to antibiotic use across studies while considering methodological diversity and limitations. Ethics and dissemination: Ethics approval is not required for this scoping review. The findings of this scoping review will be disseminated through publication in a peer-reviewed journal, presentation at relevant conferences and workshops, and collaboration with policy-makers and healthcare stakeholders.

Background: Antimicrobial resistance (AMR) is now a critical issue in South Africa, enhanced by considerable inappropriate prescribing of antibiotics. There is currently variable dispensing of antibiotics without a prescription. Where this occurs, it is principally for urinary tract infections (UTIs) and sexually transmitted infections (STIs). Consequently, there is a need to comprehensively evaluate antibiotic dispensing patterns and factors influencing this to reduce AMR. Methods: A previously piloted questionnaire was administered to patients exiting three different categories of community pharmacies in a rural province. The questionnaire included data on the prevalence of antibiotics dispensed, whether without a prescription, and the rationale for this. Results: A total of 465 patients leaving community pharmacies with a medicine were interviewed. 54.4% of interviewed patients were dispensed at least one antibiotic, with 78.7% dispensed these without a prescription from either independent or franchise pharmacies. Metronidazole (36.1%) and azithromycin (32.7%) were the most dispensed antibiotics. STIs were the most common infectious disease for which an antibiotic was dispensed (60.1%), with 99.6% dispensed without a prescription. Upper respiratory tract infections (URTIs) were the most common infection where antibiotics were dispensed with a prescription (60.0%), with little dispensing without a prescription (7.1%). The most frequently cited reasons for obtaining antibiotics without a prescription were prior use (56.8%), long waiting times at PHC clinics (15.6%), and financial constraints (6.0%). Conclusions: There is an urgent need to review community pharmacists’ scope of practice, including allowing them to prescribe antibiotics for infectious diseases such as UTIs, similar to other countries. Concomitantly, utilise trained community pharmacists to engage with prescribers to improve future antibiotic use, especially for URTIs.
