Role crisis, risk and trust in Australian general public narratives about antibiotic use and antimicrobial resistance

Ethical bioprospecting and microbial assessments for sustainable solutions to the AMR crisis

Antimicrobial resistance (AMR) has been declared one of the top 10 global public health challenges of our age by the World Health Organization, and the World Bank describes AMR as a crisis affecting the finance, health, and agriculture sectors and a major threat to the attainment of Sustainable Development Goals. But what is AMR? It is a phenotype that evolves in microbes exposed to antimicrobial molecules and causes dangerous infections. This suggests that scientists and healthcare workers should be on the frontline in the search for sustainable solutions to AMR. Yet AMR is also a societal problem to be understood by everyone. This review aims to explore the need to address the problem of AMR through a coherent, international strategy with buy-in from all sectors of society. As reviewed here, the sustainable solutions to AMR will be driven by better understanding of AMR biology but will require more than this alone to succeed. Some advances on the horizon, such as the use of bacteriophage (phage) to treat AMR infections. However, many of the new technologies and new therapeutics to address AMR require access to biodiversity, where the custodians of that biodiversity-and the traditional knowledge required to access it-are needed as key partners in the scientific, clinical, biotechnological, and international ventures that would treat the problem of AMR and ultimately prevent its further evolution. Many of these advances will be built on microbial assessments to understand the extent of AMR in our environments and bioprospecting to identify microbes that may have beneficial uses. Genuine partnerships for access to this biodiversity and sharing of benefits accrued require a consideration of ethical practice and behavior. Behavior change is needed across all sectors of culturally diverse societies so that rapid deployment of solutions can be implemented for maximum effect against the impacts of AMR.

Milk consumers in Pakistan and Italy: a comparative study on the effects of geographical affiliation, socio-demographic characteristics and consumption patterns on knowledge, attitude and perception of antimicrobial resistance

Antimicrobials are extensively used in livestock to treat common diseases, including mastitis and other bacterial infections, with around 80% of food-producing animals receiving such treatments. Despite a ban in the EU since 2006, antibiotics are still used globally for growth promotion, exacerbating antimicrobial resistance (AMR). From the consumers' point of view, the potential exposure to resistant zoonotic bacteria in animal-derived food products may represent a threat to public health. However, consumers' knowledge and attitude vary across socio-demographic characteristics and geographical location. This study aims to evaluate the knowledge, attitudes, and perceptions (KAP) of milk consumers regarding AMR in Pakistan (as a representative of low-to-middle income countries (LMICs)), compared to Italy (as a representative of high-income countries (HICs)).Data were collected via surveys from 401 Pakistani and 550 Italian milk consumers, focusing on socio-demographics, milk purchasing habits, and awareness of antibiotic residues and AMR. The study identified three principal components (PCs) influencing milk consumption: milk quality attributes and tradition, family-dependence, and eating style-dependence. A cluster analysis categorized consumers into four groups: "Attentive to milk quality attributes," "Loyal to milk," "Undecided consumer," and "Milk is essential in my food pattern."Italian consumers predominantly belonged to the "Attentive to milk quality attributes" group, valuing safety and health benefits, and were the most informed about AMR. Pakistani consumers, primarily belonging to the "Loyal to milk" group, exhibited high purchasing frequency influenced by family size but showed limited awareness about AMR risks. The "Undecided consumer" group, a mix of Italian and Pakistani individuals, lacked strong preferences and displayed moderate awareness of AMR, influenced by habitual consumption patterns.This research underscores the need for targeted educational campaigns to raise awareness about AMR and antibiotic residues in milk, particularly in LMICs. Survey findings can help to identify targeted action plans and boost policy development on AMR. Enhancing consumer knowledge through the One-Health approach could mitigate AMR risks and promote informed decision-making in milk consumption across different socio-economic contexts.

Patient and public understanding of antimicrobial resistance: a systematic review and meta-ethnography

Objectives

To further develop an understanding of laypeople's (adult patients and public) beliefs and attitudes toward antimicrobial resistance (AMR) by developing a conceptual model derived from identifying and synthesizing primary qualitative research.

Methods

A systematic search of 12 electronic databases, including CINAHL, MEDLINE, PsycINFO, PubMed and Web of Science to identify qualitative primary studies exploring patient and public understanding of AMR published between 2012 and 2022. Included studies were quality appraised and synthesized using Noblit and Hare's meta-ethnographic approach and reported using eMERGe guidance.

Results

Thirteen papers reporting 12 qualitative studies were synthesized. Studies reported data from 466 participants aged 18-90 years. Five themes were identified from these original studies: the responsible patient; when words become meaningless; patient-prescriber relationship; past experience drives antibiotic use; and reframing public perception. These themes supported the development of a conceptual model that illustrates the tension between two different assumptions, that is, how can antibiotics be used for the collective good whilst balancing the immediate needs of individual patients.

Conclusions

Findings suggest that AMR is a distinct ethical issue and should not be viewed purely as a prescribing problem. The meta-ethnography-generated conceptual model illustrates many factors affecting the public's perception of AMR. These include laypeople's own knowledge, beliefs and attitudes around antibiotic use, the relationship with the healthcare provider and the wider context, including the overwhelming influence of the media and public health campaigns. Future research is needed to explore effective health messaging strategies to increase laypeople's baseline awareness of AMR as a public threat.

The impacts of knowledge and attitude on behavior of antibiotic use for the common cold among the public and identifying the critical behavioral stage: based on an expanding KAP model

BACKGROUND

This study aims to explore the impacts of knowledge and attitude on the behavior of antibiotic use during the treatment of the common cold based on the expanding KAP model, and then identify the critical behavioral stage.

METHODS

A cross-sectional study was conducted on 815 public from 21 community health centers (CHCs) in Chongqing, China. Based on the expanding KAP model, a self-administered questionnaire was designed to measure knowledge, attitude, multi-stage behavior, and perceived threat, in which multi-stage behavior was divided into pre-use antibiotic behavior, during-use antibiotic behavior, and post-use antibiotic behavior. A structural equation model was used to examine the model fit and the direct, indirect, mediating effects, and moderating effect of the variables.

RESULTS

The expanding KAP showed good model fit indices with χ²/df = 0.537, RMSEA = 0.033, CFI = 0.973, GFI = 0.971, NFI = 0.934, TLI = 0.979. Knowledge had a positive effect on attitude (β = 0.503, p < 0.05), pre-use antibiotic behavior (β = 0.348, p < 0.05), during-use antibiotic behavior (β = 0.461, p < 0.001), and post-use antibiotic behavior (β = 0.547, p < 0.001). Attitude had a positive effect on during-use antibiotic behavior (β = 0.296, p < 0.001), and post-use antibiotic behavior (β = 0.747, p < 0.001). The mediating effect of attitude was positive among knowledge, during-use antibiotic behavior (β = 0.149, p < 0.05), and post-use antibiotic behavior (β = 0.376, p < 0.001). Perceived threat also had a positive moderating effect between knowledge and post-use antibiotic behavior (β = 0.021, p < 0.001).

CONCLUSIONS

Knowledge, attitude and perceived threat had different effects on different stages of antibiotic behavior. The critical behavioral stage prioritized the post-use antibiotic behavior and during-use antibiotic behavior over pre-use antibiotic behavior.

Identifying and Prioritising Behaviours to Slow Antimicrobial Resistance

As a nation with relatively low levels of AMR, due to both community and agricultural stewardship, as well as geographical isolation, Australia is somewhat unique. As this advantage is being eroded, this project aimed to investigate the spectrum of human behaviours that could be modified in order to slow the spread of AMR, building upon the argument that doable actions are the best-targeted and least complex to change. We conducted a workshop with a panel of diverse interdisciplinary AMR experts (from sociology, microbiology, agriculture, veterinary medicine, health and government) and identified twelve behaviours that, if undertaken by the public, would slow the spread of AMR. These were then assessed by a representative sample of the public (285 Australians) for current participation, likelihood of future participation (likelihood) and perceived benefits that could occur if undertaken (perceived impact). An impact-likelihood matrix was used to identify four priority behaviours: do not pressure your doctor for antibiotics; contact council to find out where you can safely dispose of cleaning products with antimicrobial marketing; lobby supermarkets to only sell antibiotic free meat products; and return unused antibiotics to a pharmacy. Among a multitude of behavioural options, this study also highlights the importance of tailoring doable actions to local conditions, increasing community education, and emphasizing the lack of a one-size fits all approach to tackling this global threat.

Parents' awareness of antimicrobial resistance: a qualitative study utilising the Health Belief Model in Perth, Western Australia

OBJECTIVE

This study aimed to determine local factors that promote or prevent parents' responsible use of antibiotics for their children in Perth, Western Australia.

METHODS

The Health Belief Model was used to guide this study. Four focus group discussions were conducted, with 26 participants. Participants were recruited purposively through a parent group organisation. The Framework Method was utilised to analyse the data.

RESULTS

Participants agreed that antimicrobial resistance (AMR) is a serious health problem. However, participants admitted that they lacked awareness of AMR, inhibiting their ability to assess the risks of developing AMR infections among their children. Participants knew the indications and risks of antibiotic use but still viewed antibiotics as a time-saving solution that minimised disruption to their routine. Participants' previous experiences in managing their children's illness increased their confidence and linked their positive and negative experiences with their general practitioners in their judicious use of antibiotics.

CONCLUSIONS

While parents demonstrated awareness of the indications of antibiotics, they continue to lack AMR awareness and overvalue antibiotics.

IMPLICATIONS FOR PUBLIC HEALTH

The findings highlight that incorporating parent empowerment and participation in decision-making regarding antibiotics use, and maintaining a positive relationship with healthcare providers, were important strategies to encourage the appropriate use of antibiotics.

Comparing public attitudes, knowledge, beliefs and behaviours towards antibiotics and antimicrobial resistance in Australia, United Kingdom, and Sweden (2010-2021): A systematic review, meta-analysis, and comparative policy analysis

BACKGROUND

Social and behavioural drivers of inappropriate antibiotic use contribute to antimicrobial resistance (AMR). Recent reports indicate the Australian community consumes more than twice the defined daily doses (DDD) of antibiotics per 1000 population than in Sweden, and about 20% more than in the United Kingdom (UK). We compare measures of public knowledge, attitudes and practices (KAP) surrounding AMR in Australia, the UK and Sweden against the policy approaches taken in these settings to address inappropriate antibiotic use.

METHODS

National antimicrobial stewardship policies in Australia, Sweden, and the UK were reviewed, supplemented by empirical studies of their effectiveness. We searched PubMed, EMBASE, PsycINFO, Web of Science and CINAHL databases for primary studies of the general public's KAP around antibiotic use and AMR in each setting (January 1 2011 until July 30 2021). Where feasible, we meta-analysed data on the proportion of participants agreeing with identical or very similar survey questions, using a random effects model.

RESULTS

Policies in Sweden enact tighter control of community antibiotic use; reducing antibiotic use through public awareness raising is not a priority. Policies in the UK and Australia are more reliant on practitioner and public education to encourage appropriate antibiotic use. 26 KAP were included in the review and 16 were meta-analysable. KAP respondents in Australia and the UK are consistently more likely to report beliefs and behaviours that are not aligned with appropriate antibiotic use, compared to participants in similar studies conducted in Sweden.

CONCLUSIONS

Interactions between public knowledge, attitudes and their impacts on behaviours surrounding community use of antibiotics are complex and contingent. Despite a greater focus on raising public awareness in Australia and the UK, neither antibiotic consumption nor community knowledge and attitudes are changing significantly. Clearly public education campaigns can contribute to mitigating AMR. However, the relative success of policy approaches taken in Sweden suggests that practice level interventions may also be required to activate prescribers and the communities they serve to make substantive reductions in inappropriate antibiotic use.

Antibiotics in the Community During the COVID-19 Pandemic: A Qualitative Study to Understand Users' Perspectives of Antibiotic Seeking and Consumption Behaviors in Bangladesh

INTRODUCTION

The COVID-19 pandemic is thought to have led to increased "inappropriate" or "unjustified" seeking and consumption of antibiotics by individuals in the community. However, little reference has been made to antibiotic seeking and using behaviors from the perspectives of users in Bangladesh during this health crisis.

PURPOSE

This study seeks to document how antibiotic medicines are sought and used during a complex health crisis, and, within different contexts, what are the nuanced reasons why patients may utilize these medicines sub-optimally.

METHODS

We used an exploratory, qualitative design. Forty semi-structured telephone interviews were conducted with people diagnosed with COVID-19 (n=20), who had symptoms suggestive of COVID-19 (n=20), and who had received care at home in two cities between May and June 2021 in Bangladesh. In this study, an inductive thematic analysis was performed.

RESULTS

The analysis highlighted the interlinked relationships of antibiotic seeking and consumption behaviors with the diversity of information disseminated during a health crisis. Antibiotic-seeking behaviors are related to previous experience of use, perceived severity of illness, perceived vulnerability, risk of infection, management of an "unknown" illness and anxiety, distrust of expert advice, and intrinsic agency on antimicrobial resistance (AMR). Suboptimal adherence, such as modifying treatment regimes and using medication prescribed for others, were found to be part of care strategies used when proven therapeutics were unavailable to treat COVID-19. Early cessation of therapy was found to be a rational practice to avoid side effects and unknown risks.

CONCLUSION

Based on the results, we highly recommend the take up of a pandemic specific antimicrobial stewardship (AMS) program in the community. To deliver better outcomes of AMS, incorporating users' perspectives could be a critical strategy. Therefore, a co-produced AMS intervention that is appropriate for a specific cultural context is an essential requirement to reduce the overuse of antibiotics during the COVID-19 pandemic and beyond.

Understanding antibiotic use: practices, structures and networks

In this article, we consider how social sciences can help us to understand the rising use of antibiotics globally. Drawing on ethnography as a way to research how we are in the world, we explore scholarship that situates antibiotic use in relation to interactions of pathogens, humans, animals and the environment in the context of globalization, changes in agriculture and urbanization. We group this research into three areas: practices, structures and networks. Much of the public health and related social research concerning antimicrobial resistance has focused on antibiotic use as a practice, with research characterizing how antibiotics are used by patients, farmers, fishermen, drug sellers, clinicians and others. Researchers have also positioned antibiotic use as emergent of political-economic structures, shedding light on how working and living conditions, quality of care, hygiene and sanitation foster reliance on antibiotics. A growing body of research sees antibiotics as embedded in networks that, in addition to social and institutional networks, comprise physical, technical and historical connections such as guidelines, supply chains and reporting systems. Taken together, this research emphasizes the multiple ways that antibiotics have become built into daily life. Wider issues, which may be invisible without explication through ethnographic approaches, need to be considered when addressing antibiotic use. Adopting the complementary vantage points of practices, networks and structures can support the diversification of our responses to AMR.

Changes in the Framing of Antimicrobial Resistance in Print Media in Australia and the United Kingdom (2011-2020): A Comparative Qualitative Content and Trends Analysis

Educating the public about antimicrobial resistance (AMR) is considered a key part of an optimal public health response. In both media depictions and policy discourses around health risks, how a problem is framed underpins public awareness and understanding, while also guiding opinions on what actions can and should be taken. Using a mixed methods approach we analyse newspaper content in Australia and the United Kingdom (UK) from 2011 to 2020 to track how causes, consequences and solutions to AMR are represented in countries with different policy approaches. Analyses demonstrate greater variability in the frames used in UK newspapers reflecting large hospital and community outbreaks and a sustained period of policy reform mid-decade. Newspapers in Australia focus more on AMR causes and consequences, highlighting the importance of scientific discovery, whereas UK coverage has greater discussion of the social and economic drivers of AMR and their associated solutions. Variations in the trends of different frames around AMR in UK newspapers indicate greater levels of public deliberation and debate around immediate and actionable solutions; whereas AMR has not had the same health and political impacts in Australia resulting in a media framing that potentially encourages greater public complacency about the issue.
