America’s overuse of antibiotics is driven by unnecessary outpatient prescriptions, agricultural use in livestock, and patient-provider behavioral pressures. According to the Centers for Disease Control and Prevention, at least 30% of outpatient prescriptions for antibiotics are completely unnecessary.
Key Drivers of Overuse
- Unnecessary Outpatient Prescriptions: Millions of prescriptions are written annually for viral respiratory illnesses like colds, flu, and bronchitis that do not respond to drugs.
- Broad-Spectrum Choices: Doctors frequently choose broad-spectrum antibiotics instead of narrow-spectrum alternatives when older, cheaper drugs work better.
- Provider and Patient Pressure: Clinicians often overestimate how badly patients want antibiotics, leading to an “action bias” to satisfy expectations.
- Agricultural Practices: The heavy routine use of antimicrobial drugs to promote growth and prevent disease in livestock fosters resistant strains.
- Public Health Impacts
- Drug Resistance: More than 2.8 million antibiotic-resistant infections occur in the U.S. each year, causing over 35,000 deaths.
- Secondary Infections: Widespread use spikes cases of severe conditions like Clostridioides difficile colitis.
Data Finds These States Are Driving America’s Antibiotic Overuse
New research has highlighted significant regional differences in antibiotic use and resistance across the United States.
According to CDC data, Americans were prescribed 236.4 million antibiotic prescriptions in a single year*, equivalent to roughly 709 prescriptions per 1,000 people.
In light of this, health insurance experts at Compare the Market have analyzed where antibiotic use is highest and where resistance is becoming a growing public health concern.
Top 3 states driving highest antibiotic overuse and resistance:
- West Virginia: 1,253 prescriptions per 1,000, 53.6% MRSA & highest hospital infection rate (5.14 per 1,000)
- Kentucky: 1,128 per 1,000, 55.1% MRSA & 4.52 per 1,000 infections
- Louisiana: 1,097 per 1,000, highest MRSA resistance (57.4%) & 4.09 per 1,000 infections
Which U.S. states are driving antibiotic overuse & resistance?
Summary
The data shows that Mississippi, Louisiana, Kentucky, and West Virginia are among the worst-performing states, with lower index scores, meaning they are more reliant on antibiotics, and their germs are harder to treat.
Steven Spicer, Executive General Manager of Health, Life and Energy at Compare the Market, comments: “Antibiotic resistance is a growing issue, and we all have a part to play in tackling it. By making small lifestyle changes, such as improving diet, staying active, and reducing reliance on antibiotics, we can significantly impact our long-term health.“
“Managing our health better not only improves your well-being but also helps protect the effectiveness of antibiotics for future generations. Don’t forget to also consider your health insurance coverage to ensure you’re prepared for unexpected medical expenses.”
Methodology
https://archive.cdc.gov/www_cdc_gov/antibiotic-use/data/report-2022.html
This dataset includes antibiotic usage data, which was used to create an index ranking their use in the USA and Australian States/Territories. This includes 3 metrics, each normalised between 0 and 1, and an average was used to create the index, which is out of 1.
Metrics
- Antibiotic prescriptions per 1000 population
- Antibiotic resistance percentage (The percentage of Staphylococcus aureus infections which were found to be MRSA)
- Healthcare-associated bloodstream MRSA infections per 100,000 population
Population data was taken from World Population Review.
Indexing rules
- Lower is better for all factors
