Background: As healthcare recipients and individuals affected by antimicrobial resistance (AMR), patients and their carers can be engaged in infection prevention and control (IPC) and antimicrobial stewardship (AMS) initiatives to manage AMR. To effectively participate in these initiatives, patients and carers need to understand general terms used in infection care. We explored awareness of commonly used infection-related terms among patients and carers in the surgical out-patient of a tertiary academic hospital.

Article Synopsis
  • Effective communication and teamwork in the operating theater (OT) are crucial for successful surgical outcomes, so researchers examined OT team dynamics and infection control practices using visual methods.
  • The study involved observing gastrointestinal surgical teams, mapping communication through sociograms, and conducting focus group discussions, ultimately analyzing data through both qualitative and quantitative means.
  • Findings showed that senior surgeons impact team dynamics significantly, and highlighted the scrub nurse's role as a coordinator; inefficiencies like frequent door openings during procedures pose risks for infection control, pointing to a need for improved communication and adherence to safety protocols.

Antimicrobial resistance (AMR) is a critical health challenge in Nigeria as in many other countries in the sub-Saharan region of Africa. Our article describes how the challenges in the regulation and operations of Patent and Proprietary Medicine Vendors (PPMVs) in Nigeria provide a blind spot for the underuse of antimicrobials. This article also sheds light on how patients' antibiotic use and seeking behaviour facilitate this unwholesome practice.

Objective: To explore pharmacist roles in antimicrobial stewardship (AMS) in India, South Africa (SA), United Kingdom (UK) and the factors that contribute to their participation in the programme in these countries.

Methods: Data were collected between April 2019 and March 2022 through semi-structured interviews with key AMS stakeholders from India (Kerala); SA (Western Cape province) and the UK (England). Interviews were conducted face to face or via Zoom and Skype platforms, audio recordings were transcribed verbatim and thematically analysed using a grounded theory approach aided by NVivo 12 software.

Article Synopsis
  • - Mentorship in global health research is often neglected, yet it's essential for building effective partnerships and requires value-driven approaches across cultural and hierarchical barriers.
  • - Effective mentorship must confront power imbalances regarding funding, leadership, data, and capacity development, as current equity guidelines do not adequately address these complexities.
  • - The piece emphasizes the importance of local leadership and collaboration in strengthening human capacity, highlighting that transformative mentorship practices should be guided by shared values among research teams.

Objectives: Sub-Saharan African (SSA) countries are severely impacted by antimicrobial resistance (AMR). Due to gaps in access to diagnostics in SSA, the true extent of AMR remains unknown. This diagnostic gap affects patient management and leads to significant antimicrobial overuse.

Background: The link between healthcare worker (HCW) communication, teamwork and patient safety is well-established. Infection prevention and control (IPC) and antimicrobial stewardship (AMS) require multidisciplinary teamwork and communication.

Objectives: We conducted a scoping review of published evidence on effective mechanisms of HCW team communication in hospitals with the intention of transferring and tailoring learning to IPC and AMS team communication.

A cross-sectional survey among participants in India and South Africa to explore perceptions and awareness of SARS-CoV-2-related risks. Main outcome measures-proportion of participants aware of SARS-CoV-2, and their perception of infection risks as it related to their views and perceptions on vaccination, i.e.

At the 2015 World Health Assembly, UN member states adopted a resolution that committed to the development of national action plans (NAPs) for antimicrobial resistance (AMR). The political determination to commit to NAPs and the availability of robust governance structures to assure sustainable translation of the identified NAP objectives from policy to practice remain major barriers to progress. Inter-country variability in economic and political resilience and resource constraints could be fundamental barriers to progressing AMR NAPs.

Objective: The irrational use of antibiotics is a leading contributor to antibiotic resistance. Antibiotic stewardship (AS) interventions predominantly focus on prescribers. This study investigated the influence and participation of inpatients in infection-related care, including antibiotic decision-making, within and across two tertiary hospitals in South Africa (Cape Town) and India (Kerala).

Objective: To identify perceptions and awareness of changes in infection prevention and control (IPC) and antimicrobial stewardship (AMS) practices among healthcare workers (HCWs) during the COVID-19 pandemic in India and South Africa (SA).

Method: A self-administered online survey which included participant demographics, knowledge and sources of COVID-19 infection, perceived risks and barriers, and self-efficacy. Data were analysed using descriptive statistics.

We report an empirical analysis of the use of imagery by the key actors in global health who set policy and strategy, and we provide a comprehensive overview, particularly related to images used in reports on vaccination and antimicrobial resistance. The narrative currently depicted in imagery is one of power imbalances, depicting women and children from low-income and middle-income countries (LMICs) with less dignity, respect, and power than those from high-income countries. The absence of any evidence of consent for using intrusive and out-of-context images, particularly of children in LMICs, is concerning.

This article summarizes the consequences of the COVID-19 pandemic, on an international project to tackle antimicrobial resistance (AMR). The research leadership and process, the access to data, and stakeholders were deeply disrupted by the national and international response to the pandemic, including the interruption of healthcare delivery, lockdowns, and quarantines. The key principles to deliver the research through the pandemic were mainly the high degree of interdisciplinary engagement with integrated teams, and equitable partnership across sites with capacity building and leadership training.

Background: Whilst antimicrobial stewardship (AMS) is being implemented globally, contextual differences exist. We describe how the use of a massive open online course (MOOC) platform provided an opportunity to gather diverse narratives on AMS from around the world.

Methods: A free 3 week MOOC titled 'Tackling antimicrobial resistance: a social science approach' was launched in November 2019.

The SARS-CoV-2 infection, which causes the coronavirus disease (COVID-19), has affected lives, with very adverse outcomes in specific populations in the United States of America (USA), a high-income country, and two middle-income countries, Brazil and South Africa. This paper aims to discuss the relationship of race/ethnicity with COVID-19-associated factors in the three countries. The information is based on data collected from infectious disease/epidemiological centers in the USA, Brazil, and South Africa.

Background: The effect of team dynamics on infection management and antimicrobial stewardship (AMS) behaviours is not well understood. Using innovative visual mapping, alongside traditional qualitative methods, we studied how surgical team dynamics and communication patterns influence infection-related decision making.

Materials/methods: Between May and November 2019, data were gathered through direct observations of ward rounds and face-to-face interviews with ward round participants in three high infection risk surgical specialties at a tertiary hospital in South Africa.

Economic challenges associated with noncommunicable diseases (NCDs) and the sociocultural outlook of many patients especially in Africa have increased dependence on traditional herbal medicines (THMs) for these diseases. A cross-sectional descriptive study designed to determine the prevalence of and reasons for THM use in the management of NCDs among South African adults was conducted in an urban, economically disadvantaged area of Cape Town, South Africa. In a cohort of 1030 participants recruited as part of the existing Prospective Urban and Rural Epidemiological (PURE) study, 456 individuals were identified.
