Healthcare Stewardship 7

Antimicrobial Stewardship (AMS): Strengthening Infection Prevention and Control (IPC). 

Antimicrobial resistance (AMR) stands among the greatest existential threats to global health. As bacteria, viruses, fungi, and parasites evolve to resist the drugs designed to eliminate them, our arsenal of antibiotics, antifungals, and antivirals grows weaker. Without strategic antimicrobial stewardship (AMS), we risk losing the ability to treat common infections, rendering medical procedures—from surgery to chemotherapy—dangerous or even lethal. 

Why Antimicrobial Stewardship (AMS) Matters. 

Antimicrobial stewardship (AMS) is more than a public health policy—it is an integrated systems approach to optimizing the responsible and restrained use of antimicrobial agents to combat resistance while preserving the effectiveness of existing treatments.

At its core, AMS seeks to: 

1.      Ensure appropriate use of antibiotics to prevent unnecessary prescriptions that drive resistance. 

2.      Reduce transmission of antimicrobial resistant pathogens through rigorous infection prevention and control (IPC). 

3.      Preserve last-line treatments by minimizing exposure to broad-spectrum antimicrobials. 

4.      Promote research and innovation for novel therapeutics while protecting the efficacy of current drugs. 

Without immediate intervention, AMR could return modern clinical medicine to a pre-antibiotic era where minor infections become life-threatening.

The Implications of Antimicrobial Resistance (AMR) on Global Health Security.

Antimicrobial resistance (AMR) represents a serious and accelerating threat to global health security, altering the way infections are treated and public health emergencies are managed. Its impacts cut across healthcare systems, economies, and communities, underscoring the need for urgent, coordinated action.

1.      A Return to Pre-Antibiotic Medicine. AMR threatens to make routine infections untreatable, pushing medical care backward. Procedures such as surgeries, chemotherapy, and organ transplants rely on effective antibiotics to prevent infections. Without them, once-manageable diseases like pneumonia, tuberculosis, and malaria could become deadly again.

  2.      Increased Mortality and Morbidity. Resistant infections lead to higher death rates, prolonged illness, and greater suffering. Diseases that were previously controlled—such as multidrug-resistant tuberculosis and gonorrhea—are resurging due to ineffective treatments.

 3.      Strain on Global Healthcare Delivery Systems. Hospitals face longer patient stays, higher treatment costs, and greater demand for intensive care due to AMR-related complications. The burden is disproportionately high in low-income countries, where healthcare access is already limited. 

4.      Economic Consequences.  The global economy suffers as AMR infections increase healthcare costs for prolonged treatments and specialized care, reduce workforce productivity due to longer illnesses and fatalities, and threaten food security by weakening the effectiveness of antimicrobials in agriculture.  The World Bank estimates that AMR could reduce global GDP by 3.8% annually by 2050, causing economic losses comparable to the 2008 financial crisis.

 5.      Public Health Emergencies and Pandemics. AMR weakens our ability to respond to future pandemics and outbreaks. Resistant pathogens can spread rapidly, making treatment difficult and accelerating global health crises. 

 6.      Environmental Impact. Antimicrobial resistance (AMR) is fueled by the overuse of antibiotics in agriculture, healthcare, and wastewater contamination. Resistant bacteria spread through ecosystems, affecting animal health and human exposure via food and water sources. 

What Can Be Done? 

1.      Antimicrobial stewardship (AMS) is an imperative to regulate antibiotic use in hospitals and agriculture. 

2.      Infection prevention and control (IPC) strategies must be instituted now to reduce the spread of resistant bacteria. 

3.      Investment in new drugs and diagnostics by the global biomedical-industrial complex is already under way to combat emerging resistance. 

4.      Global cooperation throughout the healthcare sector is necessary to ensure equitable access to effective treatments. 

Without coordinated action, antimicrobial resistance (AMR) could undo a century of medical progress, making even minor infections life-threatening. Preserving the effectiveness of antimicrobials is a global responsibility—and the time to act is now. 

The Role of Infection Prevention and Control. 

Antimicrobial stewardship (AMS) must be coupled with robust infection prevention and control (IPC) measures to break the cycle of resistance.

Effective IPC strategies include: 

1.      Strengthening Hygiene and Sanitation: basic public health measures—such as hand hygiene, water sanitation, and sterilization protocols—form the frontline defense against the spread of resistant microbes. Hospitals, clinics, and long-term care facilities must enforce rigorous hygiene practices to reduce healthcare-associated infections (HAIs).

 2.      Surveillance and Rapid Diagnosis: a data-driven approach to detecting outbreaks of resistant pathogens enables swift intervention. Advances in genomic sequencing and AI-powered diagnostics allow healthcare professionals to track resistance patterns and tailor antimicrobial prescriptions accordingly.

3.      Responsible Prescribing and De-escalation Strategies: physicians play a crucial role in avoiding unnecessary antimicrobial use. Prescribing targeted therapies based on lab-confirmed diagnoses, rather than empirical treatment, reduces exposure to broad-spectrum agents. De-escalation strategies, which shift patients from broad to narrow-spectrum antibiotics based on response, further mitigate resistance risks.

4.      Public Awareness and Behavioral Change: combatting AMR requires a major societal shift. Patients must be educated on avoiding self-medication, completing full antibiotic courses, and understanding the risks of misuse. Public health campaigns should integrate clear, empirically-driven evidence-based messaging to counter both misinformation and disinformation surrounding antibiotic use.

 5.      Integrating Environmental Stewardship with One Health Approach and EcoHealth Framework: the spread of AMR extends beyond human healthcare—it is deeply interconnected with animal agriculture, wastewater contamination, and environmental degradation. A One Health approach and EcoHealth framework, which unites human, animal, and environmental health strategies, is essential for comprehensive antimicrobial stewardship (AMS).

A Call to Action. 

Antimicrobial stewardship (AMS) is not a responsibility limited to public health policymakers or healthcare professionals—it requires global collaboration across all sectors. Governments, researchers, and communities must work together to: 

1.      Support investment in antimicrobial research to replenish the drug pipeline. 

2.      Advocate for stronger regulation of antibiotic use in human and veterinary medicine.

3.      Uphold infection prevention and control (IPC) measures to prevent the spread of resistant pathogens.

4.      Combat misinformation/disinformation about antimicrobial resistance (AMR) to ensure public compliance. 

The response to antimicrobial resistance (AMR) will shape the future of global healthcare delivery. Without decisive action, we risk returning to a time when routine infections are no longer treatable. Strong antimicrobial stewardship (AMS) is essential to protecting the gains of modern medicine—today and for generations to come.
