Summary

This study adapted a psychiatric symptom scale for respiratory conditions like cough and dyspnea. The modified scale accurately identified obstructive lung disease and correlated symptom severity with reduced lung function.

Area of Science:

  • Pulmonary Medicine
  • Clinical Assessment
  • Respiratory Health

Background:

  • Quantitative symptom recording is crucial for assessing respiratory conditions.
  • Existing methods may not adequately capture the nuances of symptoms like cough, breathlessness, wheezing, and dyspnea.
  • A validated, efficient tool is needed for clinical and research settings.

Purpose of the Study:

  • To adapt and evaluate a quantitative symptom recording method for respiratory symptoms.
  • To assess the method's reliability and validity in distinguishing between healthy individuals and patients with pulmonary disorders.
  • To explore the relationship between symptom scores and objective lung function measures.

Main Methods:

  • Modified a psychiatric symptom scale for four key respiratory symptoms: cough, breathlessness, wheezing, and dyspnea.
  • Evaluated the modified method in a survey of 193 healthy subjects and 186 patients with pulmonary disorders.
  • Assessed symptom scores for accuracy in discrimination and correlation with peak expiratory flow rate.

Main Results:

  • The adapted method required an average of six minutes to score four symptoms with minimal inconsistencies.
  • Cough scores differentiated healthy individuals based on smoking habits.
  • Wheezing scores were more accurate than cough, breathlessness, or dyspnea scores in distinguishing healthy individuals from those with obstructive lung disease.
  • Higher dyspnea and cough scores correlated with significantly reduced predicted peak expiratory flow rates (12% and 7% decrease per score point, respectively).

Conclusions:

  • The modified quantitative symptom recording method is a reliable and efficient tool for assessing respiratory symptoms.
  • The method demonstrates potential for clinical use in differentiating lung disease and monitoring disease impact.
  • Symptom severity, particularly dyspnea and cough, is directly associated with reduced pulmonary function.
