Chronic bronchitis terminology causes confusion. Replacing it with chronic mucus hypersecretion, which reflects airflow limitation and prognosis, is recommended for clarity in obstructive airway disease.

Area of Science:

  • Pulmonology
  • Respiratory Medicine
  • Clinical Terminology

Background:

  • The term 'chronic bronchitis' has a precise clinical definition since the 1960s.
  • Terminology for nonasthmatic, nonemphysematous obstructive airway disease remains confusing.
  • Histological studies reveal widespread bronchial inflammation in this condition.

Purpose of the Study:

  • To address the confusion surrounding terminology for obstructive airway disease.
  • To advocate for simple, descriptive terminology that emphasizes airflow limitation.
  • To propose a preferred term that accurately reflects the condition's pathology and prognostic implications.

Main Methods:

  • Review of existing clinical definitions and terminology.
  • Analysis of histological findings related to bronchial inflammation.

  • Evaluation of the impact of terminology on prognosis and clinical understanding.

    • Main Results:

    • A recent international survey indicated ongoing confusion regarding obstructive airway disease terminology.
    • Airflow limitation is a key factor influencing prognosis in these conditions.
    • Histological evidence supports the presence of bronchial inflammation.

    Conclusions:

    • The term 'chronic bronchitis' should be replaced by 'chronic mucus hypersecretion'.
    • This change would provide a clearer, more descriptive terminology for obstructive airway disease.
    • The proposed terminology better reflects the condition and its impact on prognosis.
