Abstract
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.Entities:

Figure 1Map showing study settings and population density in Malawi, Uganda and Zimbabwe. Maps were generated using ESRI ArcMap 10.8.1 (ESRI 2020; Redlands, California, USA). Population data were sourced from www.worldpop.org and consists of 2020 population estimates for each country at the scale of 100 m2 grid cells.
Overview of study settings and healthcare context
| Malawi | Zimbabwe | Uganda |
| Malawi, a country with a population of 17.6 million, is among the poorest countries in the world. | Zimbabwe has a population of 14.6 million, of which 1.5 million live in the capital of Harare. Zimbabwe ranks 150 of 189 countries in the human development index and in 2019 had a per capita GNI of $1200. | Uganda has a large population of 44.2 million and ranks 159 of 189 in the human development index, with a per capita GNI in 2019 of $780. |

†The number indicates how many different antibiotic substances were included. Where possible, we also included different modes of administration for the same substances to maximise the chances of recognition by respondents; however, these fine-grained differences are not explicitly represented in our quantitative analyses to avoid overcomplication. See online supplemental material for breakdown of drug bag contents by antibiotic substance and mode of administration.

*Respondents across all three countries generally indicated that medicines were challenging to access for reasons including affordability, stockouts and inability to obtain a prescription. Even where medicines were available, this was often at considerable expense to the household.
†In the Ugandan surveys, 'cold/flu' and 'cough' are grouped together because participants used language that combined these categories of illness.

*In MR1 and ZU1, a smaller subset of households who reported using an antibiotic during a prior fever episode were asked where the antibiotic was obtained from. In MR2, all respondents were asked about where the last antibiotic used in the household was obtained from. In UU and UR, respondents were asked to list the sources from which they generally obtain medicines, including antibiotics.
†A common theme among respondents was that the clinic shelves were perceived as often being empty, and so they felt pushed towards retail pharmacies and the informal sector to obtain antibiotics—discussed in section ‘Amoxicillin and the gaps in public sector healthcare’.
‡In Uganda, both public clinics and public hospitals were grouped together under public facilities.
