Background As concerns about the prevalence of infections that are resistant to available antibiotics increase, attention has turned toward the use of these medicines both within and outside of formal healthcare settings. Much of what is known about use beyond formal settings is informed by survey-based research. Few studies to date have used comparative, mixed-methods approaches to render visible patterns of use within and between settings as well as wider points of context shaping these patterns.
Design This article analyses findings from mixed-methods anthropological studies of antibiotic use in a range of rural and urban settings in Zimbabwe, Malawi and Uganda between 2018 and 2020. All used a ‘drug bag’ survey tool to capture the frequency and types of antibiotics used among 1811 households. We then undertook observations and interviews in residential settings, with health providers and key stakeholders to better understand the stories behind the most-used antibiotics.
Results The most self-reported ‘frequently used’ antibiotics across settings were amoxicillin, cotrimoxazole and metronidazole. The stories behind their use varied between settings, reflecting differences in the configuration of health systems and antibiotic supplies. At the same time, these stories reveal cross-cutting features and omissions of contemporary global health programming that shape the contours of antibiotic (over)use at national and local levels.
Conclusions Our findings challenge the predominant focus of stewardship frameworks on the practices of antibiotic end users. We suggest future interventions could consider systems—rather than individuals—as stewards of antibiotics, reducing the need to rely on these medicines to fix other issues of inequity, productivity and security.

What is already known?
Antimicrobial resistance is a key health challenge of our time, its rise attributed to widespread use of antibiotics.
Capturing the volume, types and stories of antibiotics used both within and outside formal prescriber settings is challenging but important to guide efforts to optimise antibiotic use.
Existing survey research in low- and middle-income countries contributes to a behaviour-oriented agenda by pinpointing demographic and educational associations with antibiotic use.
What are the new findings?
The most frequently used antibiotics among selected households in Malawi, Zimbabwe and Uganda were amoxicillin, cotrimoxazole and metronidazole.
The reasons for varying antibiotic use profiles between and within countries reflected particular histories, systems and relations.
Cross-cutting drivers of antibiotic use included gaps in public sector healthcare, the prominence of donor programmes, the lack of attention to disease prevention and deeply entrenched inequalities.
What do the new findings imply?
Research foregrounding individual characteristics and behaviour risks overlooking structural and systemic reasons for antibiotic use.
There is a need to consider systems - rather than individuals - as stewards of antibiotics ifsafe, sustainable reductions in antibiotic use are to be achieved within and beyond prescriber settings.
To mitigate against the predicted health and economic impacts of antimicrobial resistance (AMR), the WHO’s global action plan has called for improved surveillance of antibiotic use to inform antimicrobial stewardship strategies.1 Many low-income and middle-income countries (LMICs) have experienced steep rises in antibiotic use in recent decades2–6 and been identified as particular targets for interventions. Surveillance at national level has been challenging to implement, and has generally prioritised the collection of aggregated consumption data from sales and imports, accompanied by limited hospital data, and even more limited information outside of hospitals on how antibiotics are actually used by different provider types and patients.7 A particular area of concern is antibiotic use beyond formal prescriber settings (retail pharmacies, drug shops, markets, households and farms), an understanding of which is crucial for producing a comprehensive picture of antibiotic use in LMICs and for developing context-sensitive interventions, particularly in settings with large informal pharmaceutical markets.8 9 Such data, however, are more resource intensive to collect systematically than consumption and prescribing data and are made especially challenging by the fact that ‘antibiotic’ is a complex category with numerous classes and uses and does not translate well either linguistically or conceptually in many settings.10 11
A growing number of surveys, systematic reviews and meta-analyses have nonetheless begun to elucidate patterns and predictors of antibiotic use at the community level. Analyses of demographic and health surveys and multi-indicator cluster surveys suggest that the greatest rises in antibiotic use in LMICs have been among rural, the poorest and least educated populations, particularly in low-income countries and South-East Asia, although the greatest overall rates are seen in urban centres and among the most affluent and most educated demographics.3 12 Studies have further sought to capture the extent of the misuse of antibiotics, undergirded by benchmarking ‘(ir)rational’ practice against indicators of expected clinical need. Findings indicate high rates of inappropriate use across LMICs,13–16 and that non-prescription use or ‘self-medication’ can make up as much as 100% in some populations.16 A recent study identified a greater prevalence of and reliance on informal providers in Asian countries than in African countries, with self-medication generally considered a cheaper, more convenient option than attending healthcare facilities,17 although this and other studies show many factors affect if/where treatment is sought, including policy and health system context, symptoms, disease severity, distance to travel, age of patient and trust in medicines and providers.3 13 14 18 Some studies have also broken down use profiles by antibiotic type and, increasingly, have mapped these onto the WHO’s Access, Watch, Reserve (AWaRe) classification system.19 The majority of antibiotic use in LMICs appears to be predominated by substances in the Access group,13 17 20–23 although use profiles vary considerably by setting and Watch group antibiotics appear to be more widely used in Asia than in Africa.17
While quantitative survey data are important for targeting interventions to particular populations, qualitative methods are vital for explaining antibiotic use in context.24 25 A strength of social research, including the observational techniques of ethnography, is the ability to capture, analyse and articulate the often taken-for-granted backdrops that shape—and are reproduced by—the ways people live in the world. An expanding body of such research has demonstrated that many of the antibiotic use practices that would be considered ‘irrational’ from a biomedical perspective (eg, storing antibiotics for later, sharing them with others and using informal providers) are highly rational within the material and moral worlds inhabited by people living in contexts of scarcity and precarity.26–29 Anthropologists have shown that expectations for medicinal care and increasing reliance on antibiotics are tied to processes of pharmaceuticalisation that have disproportionately affected people living in LMICs, in which care has been progressively stripped to little more than the giving and receiving of medicines.26 30 31 The work of social scientists has contributed to a growing recognition of the wider structural processes shaping antibiotic use practices in LMICs and that these should be considered in stewardship strategies moving forward.32 33
In-depth qualitative approaches necessarily require a focus on particular sites and contexts. Few studies using such methods, however, have attempted the kind of multi-sited, comparative analyses more common in survey research to compare patterns of, and underlying reasons for, antibiotic use across different settings.17 18 Such research that can build in the power of comparative approaches—that render visible what might otherwise be taken for granted in a given setting—can enhance the ability of social research to contribute to interventions at multiple levels of scale. This article analyses findings from anthropological studies of household antibiotic use in Malawi, Uganda and Zimbabwe, which used mixed-methods research designs to capture, situate and compare the stories of antibiotics and their use in different settings. Our aim is both to increase understanding of patterns and reasons behind antibiotic use at community level and to contribute to ongoing debates around who or what should be considered antibiotic ‘stewards’ beyond the better-known architectures of formal prescriber settings.
Studies and settings
The data on which this article is based are drawn from anthropological research on antibiotic use in Malawi, Zimbabwe and Uganda, which took place within two projects—Febrile Illness Evaluation in a Broad Range of Endemicities (FIEBRE) and Antimicrobials in Society (AMIS)—between April 2018 and December 2020. The concept for this cross-site paper emerged during the analysis phase of both projects in late 2019. The multidisciplinary FIEBRE and AMIS teams were comprised of social scientists (mostly anthropologists), epidemiologists, clinical and laboratory scientists, pharmacists, postgraduate students, research assistants, project managers and administrators.
Malawi, Zimbabwe and Uganda are postcolonial states in sub-Saharan Africa with different historical relationships with biomedicine and antibiotics,34 but all have high rates of poverty, inequality and donor-dependent health systems. FIEBRE sites (Chikwawa District, Malawi, and suburbs of Harare, Zimbabwe) were selected to evaluate febrile illness in malaria-endemic and non-endemic settings, while AMIS sites (Kampala and Tororo District, Uganda) were selected purposively to compare urban and rural antibiotic use (figure 1). FIEBRE and AMIS focused on low-income residential areas, but there was also considerable heterogeneity between sites that enables comparison between a range of different urban and rural environments, health system contexts and degrees of poverty (table 1).
Data collection commenced with six household surveys, including two in each country (see table 2). In the FIEBRE settings (Zimbabwe and Malawi), the selection of households in the two larger surveys (ZU1 and MR1) followed the eligibility criteria for study’s clinical protocol. Specifically, community ‘controls’, matched by age, sex and residential proximity to patient cases attending outpatient facilities with febrile illness, were identified and invited to take part in the study. A survey of antibiotic use practices was conducted during the same visit as for the clinical activities among consenting households. The smaller, purposively sampled surveys (ZU2 and MR2) were conducted to include households in geographical areas of relevance to antibiotic use not captured in the larger surveys, which in ZU2 included a suburb with known informal markets for antibiotics (Mbare) and in MR2 included villages further from public healthcare facilities. The inclusion of households in these areas did not follow predefined demographic criteria, but we sought to iteratively capture a range of livelihoods and points of access to medicines and care in these settings. The AMIS surveys (UU and UR) were not attached to a clinical study and used the same sampling strategy as the smaller FIEBRE surveys within defined study areas in Uganda.
Surveys were conducted by postgraduate researchers and/or experienced research assistants. The questions asked of respondents were tailored towards each project’s aims, with AMIS seeking to understand the roles of antibiotics in lives, livelihoods and society more broadly, and FIEBRE more specifically focused on the relationship between febrile illness and antibiotic use. These differences aside, surveys commonly included questions about household context and demographics, acute illnesses frequently experienced by household members, medicines (including antibiotics) used to treat these common illnesses and challenges associated with accessing medicines and care. These core domains form the basis of the analysis we present here.
In asking households about antibiotics specifically, all surveys used a ‘drug bag’ method that we developed, methodological reflections of which are published elsewhere.11 This involved showing respondents physical samples of antibiotics to establish common referents with them without assuming that they use biomedical categories, both to stimulate deeper conversation within the interview itself and to quantitatively identify patterns of antibiotic use to be followed up on through further ethnographic fieldwork. Drug bags specific to each site were assembled by visiting all spaces where antibiotics could be acquired locally, including clinics and hospitals, retail pharmacies, drug shops, iterant drug sellers and market vendors. We included different modes of administration of the same drug where these existed, but this analysis only includes systemic formulations (ie, tablets, suspensions and injections, not topical creams or eye ointments). All drugs were clearly labelled with packaging included, so that respondents were able to recognise the drug in a number of different ways, including appearance, generic name and branding. A full breakdown of drug bag contents is provided as online supplemental material. During the surveys, a series of ‘pile sorting’ exercises were conducted to identify which antibiotics respondents recognised, had used before, used in the month preceding the survey, used ‘frequently’ (as they interpreted ‘frequently’) and were unable to access when needed (as they interpreted ‘need’). In designing these exercises, we avoided asking participants about non-prescription use unless they raised the topic themselves, to avoid imposing a normative biomedical framework that could have made respondents feel judged and thus feel reluctant to open up about the many other dimensions of antibiotic use. Quantitative data were produced by capturing the contents of the piles, while narrative qualitative data were produced through the conversations stimulated by the process.
The household surveys took place within a broader ethnographic methodology that included fieldwork in clinics, hospitals, pharmacies, markets and with residents, as well as with key stakeholders in antimicrobial use and resistance. Fieldwork, conducted by anthropologists, postgraduate researchers and research assistants, aimed to gain a deeper understanding of the social, economic and health system context of antibiotic use profiles identified during the surveys. Following Whyte et al’s observation that medicines have social lives analytically separable from those of human actors,35 our aim was to draw out the stories of antibiotics by following them as they circulated within and beyond formal healthcare settings in different countries. Households were purposively sampled for ethnogaphic research from among those who expressed interest during surveys. At each site, 15–25 households were purposively selected to capture a range of household contexts and environments. Healthcare providers accessible to these households were eligible for inclusion, including public, private and informal providers. Observation of antibiotic prescribing and dispensing took place with a total of 23 providers (4 in Malawi, 7 in Zimbabwe and 12 in Uganda). Key informants and stakeholders, including individuals with relevant knowledge and influence at local, district and national levels, were interviewed, totalling 113 over the study period (57 in Malawi, 34 in Zimbabwe and 22 in Uganda). Ethnographic observation entailed taking part in everyday routines, including management of ill health. Interviews followed tailored and regularly updated topic guides which drew on findings from other concurrent fieldwork activities. The studies in the three countries were designed collaboratively between the researchers in all three teams, who remained in frequent contact for the duration of the fieldwork and analysis to share insights, compare findings across sites and add further lines of inquiry stimulated by interim analyses.
Patient and public involvement
Participants and stakeholders were engaged throughout the research process across all settings. While protocols were being developed, key stakeholders were identified to help to refine research questions and to address ethical and logistical challenges; these same individuals, some of whom became participants in the research themselves, were regularly updated throughout the research on findings as they emerged. Preliminary findings were also shared with residents and health providers where possible, discussions which were iteratively fed back into data collection. On completion of data collection, findings were disseminated to all participants and stakeholders, a process which in turn fed back into analysis and writing of outputs, including the present article.
Data management and analysis
All data were captured and stored on encrypted devices. Data were collected using ODK and transferred to secure servers at the London School of Hygiene and Tropical Medicine (FIEBRE data) and the Infectious Diseases Research Collaboration, Kampala (AMIS data).
Quantitative data, which included quantitative survey data and basic prescribing data abstracted from field notes with antibiotic providers, was analysed using R.36 Data were analysed separately according to the protocols of each project, and when the concept for this article was developed, comparable variables were merged into unified dataframes, and descriptive statistics were reported for each variable. During the analysis, individual antibiotic substances were reclassified into antibiotic classes and WHO’s AWaRe categories to enable greater comparison between sites and to draw out implications for stewardship. Qualitative data, which included qualitative survey data as well as field notes and interview data from the ethnographic phase, were analysed using NVivo 12. Themes were generated by each country team on an iterative basis during which codes of progressively higher orders of abstraction were used to explain and theorise the data. Comparative analysis was achieved through frequent cross-site sharing of findings and discussions of themes emerging, with inter-project meetings held at least every 2 weeks for the duration of the 3.5-year projects.
Demographics and common illnesses
Across all sites, a total of 1811 households participated in the household surveys, of which 925 (51.0%) were in Malawi, 436 (24.0%) were in Zimbabwe and 450 (24.8%) were in Uganda. Demographic characteristics of households are summarised in table 3. The most common occupations across study settings were labouring (eg, building, making, fixing, cleaning or cooking), informal vending and subsistence farming, the latter the primary occupation of most rural households. Median household size varied but was greater in urban areas, with the largest households in ZU2 (median: 4). Overcrowding was especially common in high-rise flats in Mbare, where several households often occupied a single room separated by a divider. The primary respondents were predominantly female, ranging from 56.0% (UR) to 79.0% (ZU2), for various reasons, including surveys being conducted during weekday working hours, and men often referring our field team to women, who were seen to know more about care and medicines, especially for children. The median age of respondents ranged from 27 years (MR1) to 47 years (UR). The most common self-reported acute illnesses were colds, flus and coughs, but beyond this there were notable differences between settings, especially between urban and rural study sites. In urban settings, stomach pain and diarrhoea were a more regular occurrence likely due to contaminated water sources, while in rural areas, where malaria was endemic, malaria and fevers were self-reported as the most frequent causes of sickness. Households were asked how often they were able to get the medicines needed for these illnesses, the most common answer to which was ‘sometimes’ (MR1: 31.2%, ZU1: 58.9%, UU: 13.1%).
Patterns of antibiotic use
The drug bags were a source of considerable curiosity wherever we went. With word travelling quickly, surveys were usually conducted with several onlookers gathered around, attentively watching the pile sorting exercises. The main findings regarding patterns of antibiotic use are summarised in table 4. Antibiotics were widely recognised by respondents, but this varied considerably within and between settings (ranging from a median pile size of 4 in UR to 7.5 in ZU2). Some antibiotics were especially well recognised, the most familiar of which were amoxicillin, doxycycline, cotrimoxazole, metronidazole, ciprofloxacin, erythromycin and an ampicillin/cloxacillin combination drug (the latter only in Uganda). These were referred to by short-hand or brand name terms such as ‘amoxyl’ (amoxicillin), ‘cotri’ or ‘bactrim’ (cotrimoxazole), ‘doxy’ (doxycline) and ‘flagyl’ or ‘metro’ (metronidazole). These same antibiotics were most likely to have been used before, with a considerable proportion of households having used an antibiotic in the last month (range: 31.0% in ZU1–71.0% in UR). In Zimbabwe and Malawi, most households’ last antibiotic was prescribed at a public facility; in Uganda, private providers were more commonly used, particularly in Namuwongo (UU).
Aiming to determine which antibiotics featured most prominently in everyday life, we were especially interested in the category of self-reported ‘frequent use’. Most households reported frequently using at least one antibiotic, with a median of one antibiotic being frequently used in ZU1 and MR1 and two in all other surveys. Frequent use was heavily concentrated on three drugs—amoxicillin, cotrimoxazole and metronidazole—all of which belong to the WHO Access group. These drugs were the three most frequently used antibiotics in 4/6 surveys (MR1, ZU1, ZU2 and UR) and the remaining two surveys (MR2 and UU) had two of these drugs in their top three (see table 4). Expressed as a proportion of total frequent use (visualised in figure 2), amoxicillin made up the greatest proportion (range: 13.5% in UU–53.0% in ZU1), followed by cotrimoxazole (range: 8.1% in UU–37.9% in MR2) and then metronidazole (range: 6.1% in MR2–28.5% in UU). Across all our surveys, a greater proportion of households were frequently using one or more antibiotics from the Access group (range: 68.8% in ZU1–94% in UR) than from the Watch group (range: 8.3% in ZU1–25.0% in ZU2) (see table 4). The most frequently used drugs from the Watch group were ciprofloxacin, which also belongs to the Access group, and erythromycin (figure 2). We observed, however, that while frequent use of erythromycin was commonly reported in Malawi and this was the third most frequently used of all antibiotics in MR2 (table 4), its use seemed likely over-reported due to its very similar appearance and applications for pain and inflammation to ibuprofen.
With amoxicillin, cotrimoxazole and metronidazole the most frequently used antibiotics across all settings, three noteworthy features of their patterning prompted particular ethnographic attention as our research progressed: (1) amoxicillin was the most frequently used antibiotic in 4/6 surveys and in the top 3 in all (table 4), with the antibiotic making up the greatest proportion of frequent use in ZU1 (53.0%) relative to other surveys (figure 2); (2) cotrimoxazole made up a greater proportion of frequent use in the Malawian surveys than in other countries (MR1: 30.0%, MR2: 37.9%) (figure 2); and (3) metronidazole made up a greater proportion of frequent use in Uganda than in other countries, particularly Namuwongo (UU), where it was the most used antibiotic, making up 28.5% of all frequent use (figure 2). In the following sections, we home in on the biographies35 of these three antibiotics in different settings: amoxicillin in Zimbabwe, cotrimoxazole in Malawi and metronidazole in Uganda. Our aim is not to offer a representative analysis of antibiotic use in these countries, but to highlight both particular and cross-cutting features of health systems and supply chains that shape the use of these antibiotics at household level and that are pertinent for informing antimicrobial stewardship interventions.
Amoxicillin and the gaps in public sector healthcare
During ethnographic fieldwork in primary care clinics in Harare, Zimbabwe, nurses often referred to amoxicillin as the ‘drug of choice’. This is because of the drug’s centrality to the country’s national treatment guideline (EDLIZ), which specified which essential medicines should be available on the clinic shelves and how they should be used. A broad-spectrum penicillin, amoxicillin is crucial to the syndromic management approach taken by EDLIZ and is a first-line treatment for a wide range of conditions, including pneumonia, sinusitis, otitis media and urinary tract infections. In the two clinics in which we worked in Mbare and in Buduriro, amoxicillin was the most prescribed antibiotic, making up 107/253 (42.3%) and 88/258 (33.7%) of observed antibiotic prescriptions, respectively. Additionally, we found that consultations tended to gravitate around the norm and expectation of an antibiotic being given, which we similarly found in healthcare facilities in Malawi and Uganda. Because of its pervasive use in outpatient settings, amoxicillin was perhaps expectedly the most widely recognised and used across our household surveys.
However, stockouts of first-line antibiotics, including amoxicillin, were a regular occurrence in all of our study settings in Zimbabwe, Malawi and Uganda. In Zimbabwe, the situation analysis on AMR attributed stockouts to ‘a lack of finances at the national level and fragmented funding from donors, which are often interested in funding drugs for specific programmes rather than the workhorse antimicrobials’.37 As box 1 illustrates, residents in Zimbabwe like Sisi Betty were accustomed to a situation in which, more often than not, all they had to show for paying a steep user fee and queuing for hours at the clinic outpatient department was a ‘piece of paper’ with which to seek an antibiotic themselves. Purchasing from a retail pharmacy was, however, often not an option due to high medicine costs, driving people towards the informal marketplace for medicines. Indeed, with experience dictating that the clinic was unlikely to have medicines in stock, respondents reported that they were increasingly being forced to ‘bypass’ the clinic altogether to get the medicines they needed. In this process, residents used the information and experience available to them to source the correct medicine:
Amoxicillin use in Harare, Zimbabwe
Sisi Betty smiled as she quickly recognised and picked up a packet of amoxicillin as the first medicine that she recognised from a pile of antibiotics from the drug bag. This 35-year-old mother of 3 stayed just a street away from the busy marketplace of Mbare where medicines were a common sight in the hands of drug vendors. ‘This one, I bought very cheap at the market, I got two packets with 20 amoxicillin tablets for just a dollar. These days I never go to the clinic, it is a waste of time and money. The clinic shelves are empty. You only go there to pay for a card to see a nurse who only gives you a paper to go to the pharmacy. At the pharmacy, you will find everything but the prices there will tell you to go away. To get something, you are forced to buy very cheap medicine at the market like what I do. The marketplace is now my clinic’. (SM fieldnotes, Mbare, Zimbabwe, June 2018)
At times when a neighbour's child goes to the clinic and is given a prescription for a similar disease like flu you can just opt to go to the market and buy say amoxyl [sic]. You see what the medication the neighbour was told to buy, and you go to the market to buy the medication—you avoid paying consultation fee at the clinic if you check what someone else with the same condition was told to buy. The market has almost all the drugs; I buy there. (Grandmother, 49, Mbare, respondent in ZU2)
It must be stressed that the informal markets in Harare were widely viewed as a last resort, with some having realised that the cost of using a potentially substandard drug at the marketplace could eventually be even higher than the pharmacy-sourced medicines: ‘$1 for 10 pills when you buy from the street as compared with those that cost $3 from pharmacy the cost may be low but you end up going there a lot of times with no real change’ (female, informal food vendor selling mealies, Mbare). Additionally, our surveys suggest that residents reported their last antibiotic often to have been received at a clinic (37.6% in ZU1) or from a retail pharmacy (36.6% in ZU1). However, despite respondents’ observed attempts to be responsible medicines users, there was often simply no alternative than to use the informal sector given the gaps in the public healthcare system.
Cotrimoxazole and the programme landscape of ‘global health’
Unlike amoxicillin, an antibiotic that is comparatively well funded by international donors is cotrimoxazole. In Malawi, as in many LMICs, cotrimoxazole is primarily used in the management of HIV, having previously been more widely used in outpatient care (much like amoxicillin). Following WHO guidelines,38 cotrimoxazole is prescribed as part of antiretroviral therapy initiation and prescribed indefinitely afterwards as prophylaxis against opportunistic infections. In Chikwawa, such was the scarcity of essential medicines in government healthcare facilities, particularly those further away from the district hospital, that the only medicines consistently available were those funded by donor programmes. This included, most notably, antimalarials, TB medicines and HIV-related medicines, including cotrimoxazole. This meant that cotrimoxazole was routinely prescribed for acute illnesses, regardless of patients’ HIV status, simply because it was consistently in stock. Even though in Malawi, unlike in Zimbabwe, residents did not have to pay for public sector healthcare (table 1), with households surviving through subsistence farming and with almost no access to cash they were more heavily reliant on these few donor-funded medicines.
Surveys in Chikwawa revealed that cotrimoxazole accounted for a high proportion of household use, particularly MR2 which included households in more remote villages further from the district hospital. As we found, residents knew that febrile illness—an extremely common occurrence in this malaria-endemic region—would mean the prescription of either antimalarials or, if the rapid test was negative, cotrimoxazole:
My daughter had fever and general body pain, but she was not diagnosed malaria, so she was given cotrimoxazole and Panadol (paracetamol). (Female, 32, subsistence farmer, MR2)
We always get prescribed [cotrimoxazole] from the hospital when we go for treatment. (Male, 49, subsistence farmer, MR1)
However, given the considerable geographical inequalities in access to government health facilities (table 1), accessing healthcare and medications could be expensive for many. As the vignette in box 2 shows, central to household coping and care strategies was a moral economy of reciprocity that included the storing and sharing of medicines.28 Catastrophic healthcare costs could be mitigated through borrowing medicine to treat acute illness and reciprocating at a later date when one had leftover medicine. Securing access to cotrimoxazole could be further improved through having a household member or a neighbour living with HIV and who thus had a consistent supply of the medicine, a practice we also observed during ethnographic fieldwork in Uganda and Zimbabwe. The centrality of cotrimoxazole to prescribing in Malawi and, in turn, to household coping and care strategies stems from systemic prioritisation of HIV and malaria at the expense of more ‘mundane’ acute illnesses.
Cotrimoxazole use in Chikwawa, Malawi
At 21:00 one night, one of the neighbours called by the compound I was staying in. Her child had developed a fever, cough and fast breathing. The family I was staying with did not have any medicine stored that day. But one of the women in the nearby house gave them cotrimoxazole. I called by the next day to understand what had happened. The child’s mother narrated that all the local shops were closed. She had no money to hire a taxi to take the child to the hospital (approximately 8 km away on mostly dirt roads). The child’s father was away, and they couldn’t reach him because he could not afford a phone. She said her neighbour had given her 10 cotrimoxazole tablets. She was giving it to the child in the same dose they give you at the hospital—two in the morning, afternoon and evening. When I called by again, the child was better, and the mother decided not to take her to the clinic. She was relieved that the child had got better, because paying for transport had an impact on the household. They would not be able to afford food for two meals that day so they would have to go to bed on empty stomachs. When I probed around whether she would need to return the medicine, she explained that because it was cotrimoxazole it would be easy to replace. She said it was the one drug that the clinic always gives. In the household, once the patient is feeling better, she will be able to share the leftover dose. (AK fieldnotes, Chikwawa, Malawi, December 2019)
Metronidazole and the neglect of disease prevention
One consequence of the positioning of high-priority pathogens to be addressed through narrow pharmaceutical solutions is the systematic neglect of disease prevention measures, including water and sanitation infrastructure. In Namuwongo, Uganda (UU), such infrastructure was almost completely absent bar a few fee-for-use public latrines that were unaffordable to most and in any case were too dirty to use. Residents were forced to use buckets or plastic bags for toileting, disposed of in open drainage channels or community rubbish piles. Like many urban informal settlements globally, Namuwongo was portrayed in the media as an ‘illegal slum’ that was criminally inhabited. Thus, there was little more than sporadic political will to tackle these issues and, as a result, diarrhoea and the associated crippling stomach cramps were an almost daily occurrence for households. Similar struggles with persistent diarrhoea were faced by households in Harare. While many occupied legal structures in legitimate areas of the city, Harare has long been beset with dilapidated water infrastructure, which infamously caused a cholera outbreak in 2008–2009 that caused the deaths of thousands.39 With very little investment in water infrastructure since, Harare has experienced recurring and increasingly drug-resistant cholera and typhoid outbreaks to the present day.40
Metronidazole is an antibiotic and antiprotozoal drug commonly used in the treatment of anaerobic bacterial infections. In clinics in Harare, metronidazole was prescribed second only to amoxicillin. While Zimbabwe’s national treatment guideline recommends its use only for bloody diarrhoea, such was the anxiety of sending patients home without antibiotics given the cholera and typhoid situation that metronidazole was prescribed for almost all gastrointestinal symptoms. Metronidazole was widely recognised across our surveys, particularly in urban Uganda and Zimbabwe (UU and ZU1), but what surprised us was the extent of metronidazole use in Namuwongo, where three quarters of households regularly used the drug, in most cases the week preceding the survey. As box 3 illustrates, for the residents served by health providers like Maria and Martha, metronidazole was an essential antibiotic and one that could be purchased relatively cheaply and stored at home. Metronidazole made the symptoms, if not completely better, at least tolerable, and enabled the residents of Namuwongo to continue to get by. Metronidazole can, thus, be seen as a ‘quick fix’ for hygiene and productivity, enabling the everyday life to go on amid gaping structural inequalities.
Metronidazole use in Kampala, Uganda
I sat with Maria in her clinic for hours with no patients in sight. She told me she had not served any patients since she opened that morning. It had been raining all morning and according to Maria it was not surprising that she has not received any patients, ‘they do not come while it is raining.’ We talk about the flooding further down in the settlement during the rainy season. She tells me that when she first started living in Namuwongo close to 25 years ago, most of the area further downstream was a swamp with papyrus vegetation, explaining the flooding that happens when it rains. A few weeks back, I had spent some time with Martha, a long-term resident and community health worker who told me there had been a lot of diarrhoea in the area recently. She knew this because she was selling a lot of zinc and ORS that she buys at a subsidised price from an NGO that does health promotion and livelihoods improvement work within some communities in the country. I wondered if the increased diarrhoea was linked to infections from the aftermath of heavy rains and flooding that happens in the rainy season. Maria tells me she has plans to stock a lot of flagyl (metronidazole) as she expects many patients with diarrhoea now that the rains have started. (CN fieldnotes, Namuwongo, Uganda, December 2018)
Recognition of significant increases in antibiotic use in LMICs2–6 and its implications for rising AMR has led to urgent calls to understand reasons for antibiotic (mis)use, especially beyond prescriber settings.8 9 This article presents a mixed-methods, multi-country analysis of the patterns of and reasons behind household antibiotic use practices in a range of rural and urban settings in Malawi, Uganda and Zimbabwe. Embedding the use of a ‘drug bag’ survey tool11 within an overarching ethnographic methodology, we highlighted antibiotics being frequently used—most notably, amoxicillin, cotrimoxazole and metronidazole—before explaining their use in terms of systemic processes within and between settings that often elude attempts at quantification. In this discussion, we draw out the significance of our findings in relation to existing quantitative and qualitative scholarship before using our wide-angle lens to propose a decentring of individual behaviour in LMIC antimicrobial stewardship frameworks.
Quantitative data produced using the drug bag survey tool add to a growing understanding of the local contours of antibiotic use within and between study settings. Our findings are broadly consistent with Do et al’s multi-country analysis of antibiotic use in Africa and Asia, which found that access to antibiotics in African locations was generally restricted, particularly in Southern Africa.17 As the authors similarly observed in South Africa and Mozambique,17 most antibiotic use in Zimbabwe and Malawi stemmed from public sector prescribing, with use of private pharmacies and informal providers often forced by clinic stockouts. In Uganda, antibiotics were obtained from a wider range of sources, reflecting the country’s large private sector (table 1), yet even in this setting most antibiotics were oral antibiotics from the WHO’s Access group rather than classes of medicines with higher resistance potential that are to be used Watchfully.19 Our finding that antibiotic use was heavily concentrated on a limited number of Access group medicines across all our surveys is well supported in the literature. Amoxicillin, cotrimoxazole and/or metronidazole have been found to be the most widely used antibiotics by several multi-country surveys in African settings, including that by Vialle-Valentin et al in The Gambia, Ghana, Kenya, Nigeria and Uganda,13 Padget et al in Senegal and Madagascar,41 and Fink et al in Malawi, Namibia, Senegal, Tanzania and Uganda.14 In short, our quantitative data form part of a broader emerging picture in Africa of generally restricted antibiotic use with a public sector bias, predominated by use of a small number of first-line antibiotics.
In addition to the quantitative data produced during surveys, our analysis extends to in-depth ethnographic data that enable us to tell the stories of the most widely used antibiotics.35 Our findings add to a small but growing body of work that locates antibiotic use as emergent of political and economic structures and systems, thereby decentring behaviour as the focal point of antibiotic use trends.42 The amoxicillin stories showed both the centrality of antibiotics to outpatient care and their persistent under-funding in LMICs not only by national governments but also the northern donors on whom public sector care in many LMICs has been rendered dependent. Thus, residents like Sisi Betty in Harare, Zimbabwe, were forced toward the informal sector in the frequent occurrence that this drug was out of stock. If amoxicillin is the story of under-funded public sector healthcare, cotrimoxazole is the story of that which has come to fill the gap: an antibiotic funded simply by virtue of its relationship to a ‘big’ disease like HIV.43 That public sector healthcare and household coping strategies alike in rural Malawi gravitate around this old antibiotic known to have limited efficacy44 can be read as a residual consequence of the more dramatic and widely documented ‘therapeutic citizenships’45 enacted by northern-funded donor programmes in Africa. Finally, the heavy reliance on metronidazole among residents of Namuwongo, Uganda, represents the story of what has been lost in the turn towards increasingly pharmaceuticalised forms of care: the older public health emphasis on disease prevention in the form of improved hygiene and sanitation infrastructure. While some aspects of these stories are particular to each setting, they also point toward deep-seated, transnational issues that many are aware of but that tend to get back-grounded in the practice of global health.46–48 With much at stake in the allocation of risk and responsibility for rising rates of AMR globally,25 49 making explicit connections between the use of antibiotics at household level and their entanglement within wider national and transnational systems has arguably never been more important.
Our data prompt questions about how antibiotic use data can inform AMR policy. Commentators have warned of a vicious cycle of surveillance and decision-making that results in the imposition of interventions to restrict and correct antibiotic use that may not be appropriate or a high priority in LMIC settings, including education and awareness campaigns, prescribing audits and formulary restrictions.50–52 These risks may be mitigated with more situated research and interpretation of data. There has been an increase in surveillance capacity in many LMICs to understand local use and resistance profiles, some of which is sensitive to socioeconomic and political factors driving high and rising antibiotic use and resistance.3 14 53 However, the epidemiological technologies and rationalities underpinning the majority of research and surveillance on which interventions are based—even those acknowledging wider structural factors—has tended to centre the behaviour of end users, aiming to factorialise and predict ‘misuse’ by different demographic groups. Our research demonstrates the need to decentre human behaviour and bring to the fore the systemic reasons for antibiotic use. This may be challenging, given the comparatively greater availability of expertise and templates for understanding and responding to antibiotic use through a knowledge–attitudes–practices lens.54 55 This challenge is compounded by a lack of resources and support in LMICs to develop and implement national action plans.51 This underscores the need for embedded social research expertise in AMR policy and programme implementation roles.
How might antibiotic stewardship decentre human behaviour? Following a growing number of commentators advocating for stewardship frameworks that extend beyond behaviour,51 54–56 we propose that it is systems, not individuals, that should be considered stewards of antibiotics. This is not a new or especially radical proposition; successful stewardship programmes in high-income countries rely on multiple resource and organisational components.57 However, these do not easily travel, and systems for supporting stewardship in LMICs will need to be constructed in response to local scenarios. As a first step, more sophisticated methods and metrics for knowing antibiotic use in context are needed. Our mixed-methods approach grounded in the drug bag survey tool and following antibiotics beyond the moment of use represents one among a growing number of research and surveillance protocols that produce both granular user-level data and connect use profiles to the deployment of antibiotics by the systems that are entrusted to deliver medicines and care.8 11 51 Such a wide-angle lens in turn expands possible pathways for interventions to include those that are ‘structural’ or ‘AMR sensitive’—for example, health system strengthening, infrastructural improvements and poverty alleviation strategies—which may be expensive in the short term but more cost-effective in the longer term.32 33 We further contend the importance of attending to transnational dynamics between global north and south as part of stewardship frameworks. Taking systems as stewards seriously means stepping outside the entrenched ‘grooves’ within which we collectively have come to operate and to design-out our reliance on antibiotics (and narrower techniques for evaluating their use) from the architecture of global healthcare.42 50 This is a tremendous challenge and will require bold interdisciplinary collaborations, including the emerging field of implementation science58 to develop stewardship strategies for particular LMICs. However, this is far more likely than narrow behavioural approaches to result in sustainable reductions in use both within and beyond formal prescriber settings.
The approach taken in this analysis had several limitations. First, our household surveys used purposive and semi-random sampling techniques which limit the generalisability of findings to wider populations. The quantitative findings, however, are consistent with other research in sub-Saharan Africa,13 14 17 and this approach enabled us to follow a more in-depth analysis of antibiotic stories. The drug bags were time and resource intensive to assemble and implement and, particularly as part of an overarching ethnographic methodology, may not be feasible to implement in the context of routine surveillance, although elsewhere we have considered ways in which the drug bag tool could be used to generate representative data with fewer resources.11 Finally, working with different protocols in each country meant that some data, for instance, regarding household demographics, were collected differently or not at all for each dataset, limiting some of the comparability across different studies. At the same time, however, the combined analysis did not happen retrospectively; conducted within the same anthropology of AMR research group, social scientists in the FIEBRE and AMIS teams met fortnightly to compare, contrast and collectively learn from experiences in different settings. This both strengthened the immersive, single-site ethnographic studies of each country team and became the cornerstone of our cross-country analysis here. It further generated opportunities for forging not only north–south but also south–south connection and collaboration.
This article presented a mixed-methods, multi-country analysis of household antibiotic use. Drawing on survey and ethnographic data from Zimbabwe, Malawi and Uganda, the stories presented of the three most widely used antibiotics—amoxicillin, cotrimoxazole and metronidazole—illustrate cross-cutting characteristics and omissions of the national and transnational systems that are entrusted to deliver medicines and care. Our findings challenge the predominant focus of current stewardship frameworks on restrictive and corrective interventions aimed at antibiotic end users. We suggest future strategies could consider systems—not individuals—as stewards of antibiotics, reducing the need to rely on these medicines to fix other issues of inequity, productivity and security.
