Acute Bronchitis Management

Initial Assessment and Diagnosis

The American College of Physicians recommends ruling out pneumonia by evaluating for tachycardia, tachypnea, fever, and abnormal chest examination findings in patients with suspected acute bronchitis 1
Acute bronchitis is characterized by cough with or without phlegm production lasting up to 3 weeks, with normal chest radiograph findings, and is caused by respiratory viruses in 89-95% of cases 1

The American Academy of Family Physicians recommends against routine prescription of antibiotics for uncomplicated acute bronchitis, as they provide minimal benefit and contribute to antibiotic resistance 1
Purulent sputum does not signify bacterial infection and is present in 89-95% of viral cases, according to the American College of Physicians 1
The American Thoracic Society recommends against routine use of β2-agonist bronchodilators for cough in most patients with acute bronchitis 1
Expectorants, mucolytics, and antihistamines lack evidence of benefit in treating acute bronchitis, according to the American College of Chest Physicians 2

Codeine or dextromethorphan may provide modest effects on severity and duration of cough in patients with acute bronchitis, as recommended by the American Academy of Family Physicians 1
β2-agonist bronchodilators may be useful in select adult patients with wheezing accompanying the cough, according to the American College of Physicians 1

The Centers for Disease Control and Prevention recommend prescribing a macrolide antibiotic, such as erythromycin or azithromycin, for confirmed or suspected pertussis 1
Patients with pertussis should be isolated for 5 days from the start of treatment, as recommended by the American Academy of Pediatrics 1

The American Geriatrics Society recommends considering antibiotics only in high-risk patients with significant comorbidities, such as age ≥75 years with fever, cardiac failure, insulin-dependent diabetes, immunosuppression, or serious neurological disorders 1, 2
The Infectious Diseases Society of America recommends doxycycline 100 mg twice daily for 7-10 days as a first-line treatment for moderate severity bacterial bronchitis in high-risk patients 1

The American Academy of Family Physicians recommends informing patients that cough typically lasts 10-14 days after the office visit, even without antibiotics 1
Key communication strategies include referring to the condition as a "chest cold" rather than bronchitis, explaining that patient satisfaction depends more on physician-patient communication, and discussing the risks of unnecessary antibiotic use, as recommended by the American College of Physicians 1
