Introduction

Antibiotic resistance (ABR) is a critical global health issue that threatens the efficacy of antibiotics, leading to increased morbidity, mortality, and healthcare costs. The misuse and overuse of antibiotics in both human medicine and agriculture have accelerated the spread of resistant bacteria, posing severe challenges to public health systems worldwide.

Key Insights

Increased Morbidity and Mortality:
- Antibiotic resistance leads to higher rates of infections caused by multidrug-resistant and pan-resistant bacteria, resulting in increased morbidity and mortality .
- Patients with antibiotic-resistant infections have a significantly higher risk of mortality compared to those with susceptible infections.
Economic Impact:
- The economic burden of antibiotic resistance is substantial, with increased hospital stays and higher treatment costs .
- The global economic impact includes costs to patients, healthcare providers, pharmaceutical companies, and policymakers.
Spread and Mechanisms of Resistance:
- The spread of antibiotic resistance is fueled by the indiscriminate use of antibiotics in agriculture and human medicine, as well as the global movement of people and goods .
- Bacteria have developed resistance to all classes of antibiotics, often through horizontal gene transfer, creating multidrug-resistant strains.
Impact on Medical Procedures:
- Antibiotic resistance jeopardizes advanced medical procedures such as organ transplants and cancer treatments, where antibiotics are crucial for preventing infections.
Surveillance and Policy Gaps:
- There are significant gaps in the global surveillance of antibiotic resistance, and the international response has been inadequate .
- Effective measures to combat antibiotic resistance include better surveillance, development of new antibiotics, and prudent use of existing antibiotics .

Conclusion

Antibiotic resistance poses a severe threat to global health, leading to increased morbidity, mortality, and economic costs. The spread of resistant bacteria is driven by the misuse of antibiotics and global connectivity. Addressing this issue requires concerted efforts in surveillance, policy implementation, and the development of new antibiotics to ensure the continued efficacy of treatments and the safety of advanced medical procedures.
