Chronic bronchitis in childhood: what is it?

Area of Science:

• Pediatric Pulmonology
• Respiratory Medicine
• Clinical Practice Research

Background:

• Over 2.5 million children are affected by chronic bronchitis (CB) nationally.
• Understanding childhood CB characteristics and adult form similarities is limited.
• Current diagnostic and treatment approaches for pediatric CB require clarification.

Purpose of the Study:

• To investigate how pediatricians and family physicians diagnose childhood chronic bronchitis (CB).
• To evaluate current treatment strategies for CB in children.
• To compare childhood CB diagnostic criteria with established adult epidemiological criteria.

Main Methods:

• A survey was distributed to 103 pediatricians and family physicians in Tucson.
• Physicians were questioned on diagnostic criteria and common treatments for childhood CB.
• Response rate for the survey was 45%.

Main Results:

• Diagnostic criteria for CB varied among physicians; a chronic productive cough was key for only 55% of pediatricians but 74% of family physicians.
• Recurrent cough episodes (over two weeks) were important for 86% of pediatricians.
• Allergies were frequently cited as a cause, and bronchodilators were common treatments, suggesting overlap with asthma.

Conclusions:

• Pediatric CB diagnosis frequently deviates from standard adult epidemiological criteria.
• Childhood CB exhibits substantial overlap with asthma in etiology, pathophysiology, and treatment.
• Distinguishing between asthma and CB in children presents significant challenges.
