Study Notes
- Prior to the use of antibiotics in the 1930s, even minor bacterial infections could be fatal.
- Antibiotics have saved millions of lives by treating common bacterial infections and making surgery safer.
- Some bacteria have evolved to be resistant to antibiotics, as many antibiotics are derived from fungi.
- Antibiotic resistance is a major global health threat that can spread rapidly due to international travel.
- Data from 76 countries between 2000 and 2015 was used to analyze global trends and predict future growth in antibiotic consumption.
- All antibiotic consumption was converted into a standard amount called defined daily dose (DDD) to facilitate comparison between countries.
- Countries were divided into income groups for analysis: high-income, upper-middle-income, and low-and-middle-income.
- A mathematical model was developed to predict global consumption by 2030 under three different scenarios.
- In 2015, global antibiotic consumption was estimated at 42 billion DDDs, a 65% increase since 2000.
- Economic growth was linked to increased antibiotic consumption in lower-income countries.
- High-income countries experienced slight overall consumption increases but decreasing per capita rates.
- Antibiotic consumption in low-and-middle-income countries more than doubled and is rapidly closing the gap with high-income countries.
- Consumption rates of last-resort antibiotics have been increasing in all countries around the world.
- Inaction could lead to a post-antibiotic era where common bacterial infections cause deadly epidemics.
- Many poorer countries are gaining access to antibiotics as they get richer, but inequities in access persist.
- We need to ensure access to lifesaving drugs while preventing excessive and inappropriate usage in low-and-middle-income countries.
