Few appreciate the threat of antibiotic resistance to human medicine more than readers of this blog. You know antibiotics as lifesaving “miracle” drugs that treat sepsis, save victims of burns and trauma, and are crucial to survival of patients receiving transplants and cancer treatment. At the same time, you understand the devastating consequences when these drugs don’t work anymore—when infections become resistant.
The overuse of antibiotics breeds antibiotic-resistant infections that threaten patients, hospitals, and our entire health care system. Resistant infections mean more and longer hospitalizations, increased hospital costs, and higher mortality. As clinicians, it is our job to help our colleagues in the medical community and the American public better understand the risk posed by inappropriate use of antibiotics. Patients and the community benefit from more appropriate antibiotic use, which reduces risks for the individual patient as well as the entire community.
A new, first-of-its-kind analysis of antibiotic use in US doctor’s offices and emergency departments, published in the Journal of the American Medical Association (JAMA), highlights how common inappropriate antibiotic prescribing is. CDC, in collaboration with The PEW Charitable Trusts and other public health and medical experts, found at least a third of antibiotics are given when the patient does not need them. This overuse, largely due to overprescribing for relatively minor illnesses including common colds, sore throats, and ear infections – for which antibiotics are not effective – amounts to 47 million excess antibiotic prescriptions each year.
The report also notes that outpatient antibiotic prescribing varies dramatically by geographic region, with the highest rates in the South. In addition, patients many times get the wrong antibiotic, or the wrong dose, or for the wrong duration. Taking both overuse and misuse into account, estimates are that antibiotics are prescribed incorrectly about half the time.
While some patients may receive antibiotics unnecessarily, others may not receive them promptly enough – which is critical to combat fast-moving complications of infections, like sepsis. And we’ve now reached the point where antibiotic resistance leaves us with few or no antibiotics available to treat some infections, such as CRE, the nightmare bacteria.
Improving antibiotic use is a patient safety issue. Improved use will reduce adverse events such as Clostridium difficile infections, which cause almost half a million infections and at least 15,000 deaths each year. It can be done: in England, the number of C. difficile infections was reduced by well over 60 percent in recent years, largely due to improvements in antibiotic prescribing. This is one of the many reasons the President’s National Action Plan to Combat Antibiotic Resistant Bacteria calls for inappropriate antibiotic use to be halved in outpatient settings and reduced by 20 percent in inpatient settings.
CDC will continue to work with federal partners, state health departments, professional organizations, patient advocates, and the private sector to help health care providers and the public improve their understanding of when antibiotics are – and are not – needed. The fiscal year 2016 President’s budget allowed for $160 million in new antibiotic resistance funding, which CDC will use to transform how our nation tackles this problem, including improving antibiotic use and preventing infections. The additional $40 million proposed in the fiscal year 2017 budget will ensure the nation’s ability to stand up a full response faster, protecting Americans and today’s antibiotics from resistant germs sooner.
To slow the development and spread of antibiotic-resistant infections, it will be critical for every one of us to improve the way antibiotics are prescribed and used in this country. This is the only way we can preserve our dwindling arsenal of life-saving antibiotics and reduce the threat of resistant infections to improve the lives and health of Americans.
