Antibiotics are powerful, lifesaving medicines. However, when overused they can become tragically powerless against harmful germs. Overuse – in humans, pets and in agriculture – makes antibiotic resistance much more likely. It is increasingly one of the most dangerous threats to public health.
Antibiotic resistance happens when germs develop the ability to overpower the antibiotics created to kill them. It’s not your body that becomes resistant to antibiotics, but the infection-causing germs that become resistant.
It is very difficult – if not impossible – to kill antibiotic-resistant germs. Getting an antibiotic-resistant infection likely means a long hospital stay, multiple follow-up doctor visits, and often costly and toxic alternative treatments to cure the infection.
At least 23,000 to 38,000 Americans die annually as a direct result of antibiotic-resistant infections. The additional cost of treating these infections is more than $70 billion a year.
What causes resistance?
Like no other drug, antibiotics used by one person can reduce their effectiveness in another person. That’s because the more antibiotics are used, the more quickly bacteria can mutate and develop resistance. Some bacteria can change every 40 minutes. Bacteria are emerging or changing faster than the development of new antibiotics. As soon as antibiotics were first developed about 75 years ago, bacteria began to develop resistance. Antibiotic resistance is part of the natural process of evolving bacteria. Resistance can be slowed, but not stopped.
When you take an antibiotic or even use antibacterial soap, bacteria are killed, but some resistant germs are left to grow, multiply and cause more illness. In addition to bacteria, many fungi, viruses and parasites have also changed and can no longer be stopped by antibiotics.
Here’s how resistance happens. Germs enter your body and, for several reasons (age, poor health, chronic conditions, recent surgery), they overwhelm your immune system. Your doctor prescribes antibiotics that kill most of the bacteria. But, the resistant bacteria continue to multiply. They can give their antibiotic-resistant traits to other bacteria, making them resistant, too.
Your doctor may prescribe a second antibiotic, but it may meet similar resistance. When first- and second-line antibiotics fail, third- or fourth-line antibiotics are used. These are more toxic, less effective and more expensive. Patients with resistant infections are much more likely to die. If they survive, they have significantly longer hospital stays, delayed recuperation and more long-term disability. Health care costs double when treating antibiotic-resistant infections.
More than 2.25 million people a year get a serious infection from bacteria that is resistant to one or more antibiotics. Several key antibiotics are already useless for specific infections such as pneumonia or staph. Patients receiving antibiotics have a seven- to 10-fold increased risk of developing a Clostridium difficile infection (CDI). CDI alone accounts for 453,000 infection cases and 15,000 deaths annually; plus $1 billion in direct health care costs. Methicillin-resistant Staphylococcus aureus (MRSA) kills more than 19,000 Americans every year – more than emphysema, HIV/AIDS, Parkinson’s disease and homicide combined.
Who’s at risk?
Every one of us faces the potential risk of antibiotic-resistant infections. Every time antibiotics are used, there is risk for resistance to develop.
Many of the advances in medical treatment such as joint replacements, cardiac bypass, organ and bone marrow transplants, cancer therapy, dialysis, and treatment of chronic diseases (diabetes, asthma and rheumatoid arthritis are examples) depend on the ability to fight infections with antibiotics. If that ability is lost, many of the life-saving and life-improving medical advances will be ineffective.
The threat caused by antibiotic resistance is especially dangerous in Arkansas. The Centers for Disease Control and Prevention (CDC) ranks Arkansas sixth in the nation in number of antibiotics prescribed to humans. The CDC says there are 1,155 antibiotic prescriptions per 1,000 Arkansans, compared to the national average of 835 per 1,000 Americans.
In addition to overprescribing, risk is increased because of the widespread use of antibiotics in agriculture and production of meat, poultry and fish. Veterinary medicine also contributes to resistance through overprescribing for our pets.
Prevention is best strategy
To prevent more antibiotic resistance, we must use proven public health strategies: vaccines, infection control, food supply protection, antibiotic stewardship, and consumer and provider education. Try these successful prevention tips:
Tips to prevent resistance
Relying on the drug industry to develop new antibiotics is not an immediate solution. There’s very little profit in developing a new antibiotic. The failure rate for antibiotics, from discovery to drug approval, is 97 percent. Hospitals tightly control the use of new antibiotics to prevent resistant bacteria. Drug companies cannot charge more for the new drugs to compensate for slow adoption. New drugs must be priced to compete with older and less expensive generic antibiotics. Only about 10 new antibiotics have been approved in the past 20 years. Each of them is already experiencing some degree of resistance.
Overuse and misuse of antibiotics is a growing threat to our nation’s health and security. Antibiotics can produce miracles, but some bacteria seem to be able to resist any antibiotic we throw at them. The only solution is to prevent infections and more carefully use the antibiotics we have. The safe use of antibiotics begins with YOU.
