Guideline Alignment and Medication Concordance in COPD.

Area of Science:

• Pulmonary Medicine
• Health Services Research

Background:

• Provider adherence to COPD clinical guidelines is suboptimal.
• Successful patient-provider communication is crucial for guideline-aligned care and medication concordance.
• The rates of medication concordance and its clinical impact in COPD are not well understood.

Purpose of the Study:

• To assess guideline alignment and medication concordance in COPD patient care.
• To identify patient-specific factors associated with poor disease management outcomes.

Main Methods:

• Secondary analysis of the Medication Adherence Research in COPD study (2017-2023).
• Categorized participants by Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage.
• Classified medication regimens as aligned or nonaligned with 2017 GOLD guidelines, noting overuse/underuse.
• Determined medication concordance between provider and patient reports.
• Used logistic regression to evaluate factors associated with alignment and concordance.

Main Results:

• 51% of provider regimens were guideline-aligned; 86% of nonaligned regimens involved inhaled corticosteroid (ICS) overuse.
• 38% of patients reported different regimens than providers, primarily due to unreported medications.
• Greater symptom burden, lack of a pulmonologist, cognitive impairment, and Black race were linked to misalignment and/or discordance.

Conclusions:

• Guideline misalignment and medication discordance are prevalent in COPD management.
• Overuse of ICSs and unreported medications contribute significantly to these issues.
• Patient-level factors underscore the need for improved patient-provider communication to enhance COPD clinical outcomes.
