Chronic cough, lasting over 8 weeks, often stems from post-nasal drip, asthma, or GERD. A new model suggests chest X-ray and spirometry initially, acknowledging multiple causes and guiding effective treatment strategies.

Area of Science:

  • Pulmonology and Gastroenterology
  • Internal Medicine

Context:

  • Chronic cough is defined as a cough lasting longer than 8 weeks.
  • Common causes include post-nasal drip (PND), bronchial asthma, and gastro-esophageal reflux (GERD), accounting for 90% of cases.
  • Medical history, physical examination, and exclusion of post-infectious cough or ACE inhibitor-related cough are crucial initial steps.

Purpose:

  • To present a systematic investigative model for chronic cough.
  • To emphasize the frequent multifactorial nature of chronic cough (at least two etiologies in 25% of cases).
  • To guide clinicians toward effective diagnostic and therapeutic strategies, reducing the incidence of idiopathic or psychogenic cough diagnoses.

Summary:

  • A new evaluation model for chronic cough recommends chest X-ray and spirometry as initial investigations.

  • Systematic investigation of PND, asthma, and GERD is essential.
  • Effective treatment often involves multiple medication trials, and a multidisciplinary approach is advised.

    • Impact:

    • Facilitates a more accurate and efficient diagnosis of chronic cough.
    • Improves patient outcomes by identifying underlying causes and guiding targeted therapies.
    • Reduces the likelihood of misdiagnosing chronic cough as idiopathic or psychogenic, ensuring appropriate management.
