Inappropriate Antibiotic Prescribing Leads to Increased Costs Complications

Research underscores importance of expanding outpatient antibiotic stewardship efforts

Complications with Inappropriate Antibiotic Prescribing

Inappropriate antibiotic prescribing in doctors’ offices and other outpatient settings in the U.S. is a widespread problem that accelerates the spread of antibiotic-resistant bacteria.

Among privately-insured patients diagnosed with Common bacterial infections 31%-36% of children ... received an inappropriate type of antibiotic. (i.e., not the recommended, or first-line, antibiotics based on medical guidelines). 43%–56% of adults  ... received an inappropriate type of antibiotic. (i.e., not the recommended, or first-line, antibiotics based on medical guidelines)…Common viral infections 4%–70% of children received unnecessary antibiotics:  Bronchitis: 70%, Nonsuppurative middle ear infection: 48%, Viral upper respiratory infection: 12%, Bronchiolitis: 9%, Influenza: 4%. 7%–66% of adults received unnecessary antibiotics: Bronchitis: 66%, Nonsuppurative middle ear infection: 52%, Viral upper respiratory infection: 32%, Bronchiolitis: N/A, Influenza: 7%
Inappropriate prescribing of these drugs also has measurable costs, both in terms of health care dollars and patient safety. Increased health care costs In 2017, inappropriate prescribing of antibiotics for patients with common infections resulted in $74 million in excess health care costs for pediatric patients. Nearly $69 million in excess health care costs for adult patients. Inappropriate antibiotic prescriptions for common infections are major drivers of avoidable health care costs: Suppurative middle ear infections, $25.3 million (children), Pharyngitis (sore throat) $21.3 million (children), $49.6 million (adults). Sinusitis (sinus infections), $7.1 million (children), $19.1 million (adults). Viral upper respiratory infections (the common cold), $19.1 million (children).
Adverse patient outcomes. Inappropriate antibiotics were associated with an increased risk of adverse drug events: Clostridioides difficile infection (C. diff), formerly known as Clostridium difficile, is a potentially life-threatening infection that can be caused by antibiotic exposure. The Centers for Disease Control and Prevention classifies C. diff as one of the top five most urgent pathogens. Patients who received inappropriate antibiotics for pharyngitis (sore throat) were significantly more likely to get a C. diff infection: 8x higher risk (children), 3x higher risk (adults). Other adverse events that increase with inappropriate antibiotics include: Anaphylaxis, Diarrhea, General allergic reaction, Nausea/vomiting/abdominal pain. Solutions. Health care organizations, including payers and health systems, have a key role to play in increasing antibiotic stewardship efforts and improving prescribing practices in outpatient settings, which research shows will protect patients and save money. Stakeholders can: Leverage data to assess antibiotic prescribing practices and share personalized feedback with providers. Incentivize prioritization and expansion of antibiotic stewardship efforts by incorporating stewardship into health care quality improvement efforts. Educate patients and providers on antibiotic resistance and the need for antibiotic stewardship.
