Launch Date: August 5, 2025
Expires: August 31, 2027

Course #1002
15 Credits/Hours

Course Overview

Chronic cough is a prevalent and often debilitating condition, affecting a significant portion of the adult population. Characterized by a cough lasting longer than eight weeks, it is frequently resistant to initial treatments and can persist for years. Despite repeated clinical evaluations, many patients continue to suffer without a clear diagnosis or effective therapeutic plan. Modern research has identified that hypersensitivity of the vagal afferent neurons—both in the airway and in central nervous system projections—plays a central role in chronic cough, regardless of the initial cause or any concurrent conditions. This physiological shift redefines chronic cough as a distinct clinical entity rather than a mere symptom of another disorder. Recognizing this distinction is essential for clinicians in selecting appropriate diagnostic and therapeutic strategies (Source: National Institutes of Health).

Course Objective

Chronic cough is notoriously difficult to diagnose and manage, often leading to delays in treatment and a significant decrease in patient quality of life. This course aims to equip healthcare professionals with comprehensive, evidence-based knowledge for identifying and managing chronic cough, irrespective of the underlying cause. The content is based on current clinical guidelines and incorporates up-to-date research findings from leading health organizations and peer-reviewed studies.

Learning Objectives

By the end of this course, participants will be able to:

• Define and explain chronic cough, including associated terminology and clinical definitions.
• Assess and apply standardized measures for evaluating cough severity.
• Describe the prevalence, demographics, and risk factors related to chronic cough.
• Analyze the multifaceted impact of chronic cough on physical, psychological, and social well-being.
• Outline the natural progression and long-term implications of chronic cough in adults.
• Explain the neurophysiological mechanisms underlying chronic cough.
• Conduct a structured clinical evaluation of patients presenting with chronic cough.
• Identify and manage common and uncommon causes of chronic cough, including respiratory and gastrointestinal etiologies.
• Compare available treatment strategies for various forms of chronic cough, guided by clinical evidence.
• Evaluate management options for refractory chronic cough, including pharmacologic, non-pharmacologic, and investigational interventions.
