A questionnaire validated using local treatment guidelines may better predict future asthma risk: MARGIN study

Area of Science:

• Pulmonology
• Clinical Research
• Patient-Reported Outcomes

Background:

• Asthma patient satisfaction with treatment often contrasts with physician assessments of control.
• Discrepancies in evaluating asthma control levels between patients and physicians can impact risk prediction.
• Understanding these differences is crucial for optimizing asthma management strategies.

Purpose of the Study:

• To investigate discrepancies in asthma control evaluations between patients and physicians.
• To identify predictive factors for future asthma exacerbations.
• To enhance the assessment of asthma control and reduce future risks.

Main Methods:

• A 24-week follow-up study of 420 asthma patients on inhaled corticosteroid/long-acting beta-2 agonist therapy.
• Physician assessments using Japan Guideline (JGL) and Global Initiative for Asthma (GINA).
• Patient assessments using Japan Asthma Control Survey (JACS) and Asthma Control Questionnaire (ACQ6).

Main Results:

• Physician (JGL) and patient (JACS) assessments showed similar distributions of asthma control.
• Patient (ACQ6) and physician (JGL, GINA) assessments revealed significant differences in control evaluation.
• Predictors of exacerbation included unscheduled visits (GINA) and oral steroid use (JGL, JACS).

Conclusions:

• Utilizing treatment guidelines and validated local questionnaires improves asthma control assessment.
• Aligning physician and patient evaluations is key to reducing future asthma-related risks.
• This approach supports more accurate risk stratification and personalized asthma management.
