Musaiwale Kamfose

Antimicrobial resistance (AMR) poses a significant threat to global health, particularly in low- and middle-income countries (LMICs), where access to effective treatments and `healthcare resources is limited. Over 700,000 lives are lost globally annually due to AMR (O'Neill, 2017), with a high burden of lives lost on LMICs. The World Bank estimates a global domestic product per annum reduction of 1.1% to 3.8% by 2050 if AMR remains unchecked.

As of 2020, Malawi was estimated to have a population of 19.1 million inhabitants with a life expectancy of 64 years. The country has a high infectious disease burden, with a TB incidence of 141 per 100,000 and an HIV prevalence of 8.1%. The country has a physician density rate of 0.04 per 1,000 inhabitants and a nurse density rate of 0.44 per 1,000 inhabitants. 

In Malawi, Overuse and misuse of antimicrobials are crucial factors in the complex web of AMR causation. Widespread and unregulated antimicrobial usage exerts selective pressure by reducing some microorganisms' reproductive success and consequently accelerating the development of AMR. Close surveillance of how antimicrobials are utilised is crucial for a stewardship programme to stem AMR.

The solutions serve a variety of stakeholders, and these stakeholders include:

Healthcare Professionals: Our solution provides healthcare professionals with access to up-to-date information on antimicrobial resistance patterns, treatment guidelines, and best practices for antimicrobial stewardship. This assists them in making informed decisions regarding antibiotic prescribing and managing infections effectively.

Researchers: Researchers can leverage the solution to access vast amounts of data on AMR, including epidemiological trends, mechanisms of resistance, and novel treatment strategies. This helps them in research to develop new antimicrobial agents, diagnostic tools, and preventive measures.

Policymakers and Public Health Authorities: The solution offers policymakers and public health authorities insights into the magnitude of the AMR problem, enabling them to develop and implement evidence-based policies and interventions to combat AMR at national and global levels.

Pharmaceutical Industry: The pharmaceutical industry can benefit from the solution by gaining insights into the evolving landscape of AMR, identifying opportunities for developing targeted solutions, and optimising existing therapies to mitigate resistance.

Patients and the Public: Patients and the public will be able to utilise the solution to educate themselves about AMR, understand the importance of responsible antibiotic use, and adopt preventive measures to reduce the spread of resistant infections.

This solution to antimicrobial resistance (AMR) provides several significant public goods:

Preservation of Effective Antibiotics: The solutions will help preserve the effectiveness of existing antibiotics by promoting responsible use and reducing the emergence and spread of resistant bacteria.

Improved Healthcare Outcomes: By preventing and controlling antimicrobial-resistant infections, AMR solutions contribute to better healthcare outcomes for individuals and communities. Effective treatment of infections reduces morbidity, mortality, and the burden of an already fragile healthcare system, resulting in improved quality.

Global Health Security: Addressing AMR in Malawi and low-income countries is essential for global health security, as antimicrobial-resistant pathogens can spread across borders through travel, for example, during the COVID-19 pandemic.

Sustainable Agriculture and Food Safety: This solutions promote sustainable agriculture and food safety by addressing antimicrobial use in livestock, aquaculture, and crop production.

Economic Benefits: Combatting AMR yields economic benefits by reducing healthcare costs associated with treating resistant infections, hospitalisations, and complications. It also enhances productivity and economic growth by preserving the effectiveness of antibiotics for essential medical procedures, such as surgeries, cancer treatments, and organ transplants.

Environmental Protection: This solution contributes to environmental protection by minimising ecological contamination with antimicrobial residues and resistant bacteria, healthcare facilities, and agricultural activities. 

This proposed solution is comprehensive and goes to the core benefit of the user. For example, 

Education and Awareness Campaigns: Implementation of educational campaigns through various channels (e.g., community workshops, educational materials, social media) will achieve significant output in increased knowledge and awareness among the target population about the importance of responsible antibiotic use and the risks of AMR. It will also improve adherence to antibiotic prescriptions, reduce unnecessary antibiotic use, and increase recognition of the role of individuals in combating AMR.

Access to Healthcare Services: Enhancement of access to healthcare services through mobile clinics, telemedicine, or community health workers will increase the utilisation of healthcare services for timely diagnosis and appropriate treatment of infections. 

Strengthening Antimicrobial Stewardship in Healthcare Facilities: The implementation of antimicrobial stewardship programs in healthcare facilities serving vulnerable populations, including training for healthcare providers, development of treatment guidelines, and establishment of surveillance systems will result in improved antibiotic prescribing practices.

Integration with Community Health Programs: AMR interventions into community health programs targeting maternal and child health, HIV/AIDS, or tuberculosis programs will increase the coverage and effectiveness of AMR interventions.

Increased Awareness and Engagement: The program will raise awareness about AMR among key stakeholders. Awareness campaigns, educational workshops, and advocacy efforts will be intensified to highlight the urgency of addressing AMR and mobilizing support for action. 

Policy Development and Implementation: working closely with policymakers to develop and implement comprehensive policies and regulations to address AMR at national, regional, and global levels. This will include strategies to promote antimicrobial stewardship, regulate antibiotic use in healthcare and agriculture, and strengthen surveillance systems.

Capacity Building and Infrastructure Development: The program will invest in building the capacity of healthcare systems, laboratories, and health infrastructure to prevent, diagnose, and manage AMR effectively. 

Research and Innovation: More importantly, research initiatives will be scaled up to generate evidence-based solutions for addressing AMR, including novel diagnostics, treatments, and interventions to promote behavioUr change. Collaboration with academia, industry, and international research networks will be fostered to accelerate the development and translation of innovative technologies and interventions.

Global Collaboration and Partnership: Foster collaboration and partnership across sectors and borders to address AMR comprehensively, such as the World Health Organization (WHO), Food and Agriculture Organization (FAO), and World Organization for Animal Health (OIE) and Participation in global initiatives, 

Baseline Assessment: The proposed solution will use an initial assessment to establish baseline data on indicators related to AMR prevalence, antibiotic use, healthcare-associated infections, antimicrobial stewardship practices, public awareness, and policy implementation.

Key Performance Indicators (KPIs): The project will define specific, measurable indicators aligned with the program's impact goals. Examples of KPIs include:

• • Reduction in the incidence of healthcare-associated infections caused by antibiotic-resistant pathogens.
  • Decrease in inappropriate antibiotic prescribing.
  • Increased public awareness and knowledge about AMR.
  • Implementation of policy and regulatory measures related to antimicrobial stewardship.

Data Collection and Reporting: Establish a robust data collection system to capture relevant data on KPIs.

Monitoring Activities: Monitoring program activities and outputs to track progress towards achieving desired outcomes. 

Evaluation Framework: Framework to assess the program's impact on AMR-related outcomes over time. i.e., mixed-method approaches, including quantitative analysis and qualitative research.

Stakeholder Engagement: Healthcare providers, policymakers, researchers, and community members will be engaged in the monitoring and evaluation process.

Reporting and Dissemination: Regularly report program progress, achievements, and challenges through internal reporting mechanisms and public dissemination channels. 

Adaptive Management: Use M&E findings to inform adaptive management strategies and decision-making processes. 

Several barriers could impede achieving goals in addressing antimicrobial resistance (AMR).
