Introduction: Why AMR and AMS Matter in 2024
Antimicrobial resistance (AMR) remains a pressing global health crisis, with its implications threatening the efficacy of life-saving treatments. In 2024, the urgency to address AMR has intensified, driven by its growing impact on healthcare systems worldwide. Antimicrobial stewardship (AMS) emerges as a pivotal strategy to mitigate the spread of resistance by promoting the judicious use of antibiotics and preserving their effectiveness for future generations.
This article highlights significant advancements in AMR and AMS from the past year, summarising key research findings and their implications for global health. By reflecting on these developments, we aim to provide actionable insights for advancing AMS strategies and addressing the ever-evolving challenges posed by AMR.

Study 3: Impact of COVID-19 on ‘Start Smart, Then Focus’ Antimicrobial Stewardship at One NHS Foundation Trust in England
Key Findings:
- Patient Profile: The study analysed 640 adult patients admitted for RTIs, including pneumonia and COVID-19 cases (2020), with the majority aged 66–85 years.

- Antibiotic Reviews: Reviews were conducted within 48–72 hours post-admission with no significant timing differences between 2019 and 2020.
- AMS Interventions: During the pandemic, significant differences were observed in ‘Continue Antibiotics’ (OR 3.36, p = 0.015) and ‘De-escalation’ (OR 2.77, p = 0.005) interventions, highlighting a shift in AMS practices.
Implications:
- The findings highlight the critical role of the ‘Start Smart, Then Focus’ framework in ensuring timely and effective AMS interventions during the pandemic.
- Enhanced AMS practices, including de-escalation, were vital in combating AMR risks amid increased antibiotic use during the pandemic.
- Comorbidities play a crucial role in AMS decision-making, underlining the need for tailored interventions for vulnerable populations.
Future Directions:
- Conduct further studies to explore the long-term impact of AMS adaptations during the pandemic on AMR trends.
- Investigate the scalability of SSTF guidelines across different healthcare settings.
- Develop targeted AMS strategies for high-risk groups, integrating digital tools to optimise antibiotic stewardship.
- Strengthen AMS training for healthcare professionals to ensure adherence to SSTF principles in crisis scenarios.

Study 4: An Evaluation of the Five Rights of Antibiotic Safety Before and During COVID-19 at an NHS Foundation Trust in the United Kingdom
Key Findings:
- Antibiotic Prescribing Practices:
- Increased instances of inappropriate dosing and administration routes during the pandemic.
- Slight improvement in prescribing durations, reflecting some adherence to AMS guidelines.
- Stable rates of appropriate antibiotic selection aligned with antimicrobial guidelines, despite other inappropriate practices.
- Impact of COVID-19: The pandemic exacerbated inappropriate prescribing patterns, highlighting challenges in maintaining AMS during health crises.
Implications:
- Strengthened AMS Practices:
- Findings underscore the critical role of the 'Five Rights of Antibiotics' (right patient, right drug, right dose, right route, right time) in maintaining antibiotic safety.
- Stable antibiotic selection rates reflect the potential for adherence to guidelines even under pandemic pressures.
- AMS Education and Oversight:
- Increased educational initiatives targeting appropriate dosing and administration practices are necessary.
- Systematic oversight is vital to address gaps in prescribing during emergencies like COVID-19.
Future Directions:
- Enhanced Training: Develop focused AMS training programmes for healthcare professionals to reinforce the principles of the 'Five Rights.'
- Real-Time Monitoring Tools: Introduce digital AMS tools for real-time prescribing guidance and error detection.
- Crisis Preparedness: Conduct scenario-based studies to simulate AMS challenges in future health crises and create resilient prescribing strategies.
- Broader Evaluations: Expand the study to assess AMS practices across multiple NHS Trusts for a comprehensive understanding of prescribing trends.
