The American College of Physicians (ACP) has issued Best Practice Advice with recommendations for the appropriate use of antibiotics for four common bacterial infections, as overuse, resistance, and long and unnecessary use remain major health care issues. “Appropriate Use of Short Course Antibiotics in Common Infections: Best Practice Advice from the American College of Physicians,” published in Annals of Internal Medicine, addresses best practices for prescribing appropriate and short-duration antibiotics for patients presenting with these infections.
ACP’s Best Practice Advice paper, authored by ACP’s Scientific Medical Policy Committee, defines appropriate antibiotic use as prescribing the right antibiotic at the right dose for the right duration for a specific infection. The paper was developed by conducting a narrative literature review of published clinical guidelines, systematic reviews, and individual studies that addressed uncomplicated bronchitis with COPD exacerbations, community-acquired pneumonia, urinary tract infections, and cellulitis. When clinically safe and supported by evidence, shortening antibiotic duration decreases overall antibiotic exposure, reducing the risk for resistant organisms to develop, as well as lowering a patient’s risk for adverse side effects.
The ACP’s Best Practice Advice addresses the appropriate use of short-course antibiotics in treating symptomatic adults with four common infections:
- COPD Exacerbation and Acute Uncomplicated Bronchitis: Clinicians should limit antibiotic treatment duration to five days when managing patients with COPD exacerbations and acute uncomplicated bronchitis who have clinical signs of a bacterial infection (presence of increased sputum purulence in addition to increased dyspnea and/or increased sputum volume).
- Community Acquired Pneumonia: Clinicians should prescribe antibiotics for community-acquired pneumonia for a minimum of five days. Extension of therapy after five days of antibiotics should be guided by validated measures of clinical stability, which include resolution of vital sign abnormalities, ability to eat, and normal mentation.
- Uncomplicated Urinary Tract Infection: In women with uncomplicated bacterial cystitis, clinicians should prescribe short course antibiotics with either nitrofurantoin for five days, trimethoprim-sulfamethoxazole (TMP-SMZ) for three days, or fosfomycin as a single dose. In men and women with uncomplicated pyelonephritis, clinicians should prescribe short course therapy either with fluoroquinolones (5-7 days) or trimethoprim-sulfamethoxazole (14 days) based on antibiotic susceptibility.
- Cellulitis: In patients with nonpurulent cellulitis, clinicians should use a 5-6 day course of antibiotics active against streptococci, particularly for patients able to self-monitor and who have close follow up with primary care.
In the United States, at least 30% of antibiotics use were considered unnecessary and often continued too long. The ACP and the Centers for Disease Control and Prevention (CDC) have recognized antibiotic resistant infections as a national threat.
“This guidance on appropriate use of antibiotics is important for practicing physicians when treating these common conditions in our patients,” said Jacqueline W. Fincher, MD, MACP, President, ACP. “As antibiotic resistance remains a huge issue in the U.S., educating our clinicians to adopt shorter course antibiotic therapy is paramount.”
