Factors Associated with Non-Adherence to Self-Management Among Patients with Chronic Obstructive Pulmonary Disease: A Survey Using the Delphi Technique and Analytic Hierarchy Process

Background: The relevant factors and patterns of non-adherence to self-management among patients with chronic obstructive pulmonary disease (COPD) need to be elucidated to improve self-management.
Purpose: This study was a survey to prioritize the relevance of factors associated with non-adherence to COPD self-management using the Delphi technique and analytic hierarchy process (AHP).
Patients and Methods: A total of 15 expert panels were established to determine the priority of relevant factors in a three-round Delphi survey and an AHP. To develop the preliminary conceptual framework for non-adherence to COPD self-management, findings from a systematic literature review, a qualitative study using in-depth interviews with COPD patients, and the first round of the Delphi survey were integrated. Based on the preliminary framework, the content validity ratio (CVR) was analyzed to examine the consensus among expert panels in the second and third rounds of the Delphi survey, and the relative weight was determined by pairwise comparisons between alternative factors in the AHP.
Results: In developing the preliminary conceptual framework, 8 factor categories and 53 factors were identified as relevant to non-adherence to COPD self-management. Of the 53 factors, 22 factors with a CVR of 0.49 or higher were identified in the Delphi survey. A total of 14 of the 53 factors were common to both the Delphi survey and AHP with high weights. The most notable factors were prolonged treatment, experience of treatment failure, and unknown effects of medication.
Conclusion: Through consensus decision-making by experts, 14 factors were identified as relevant factors associated with non-adherence to COPD self-management. A hierarchical and systematic framework incorporating factors associated with non-adherence to COPD self-management was developed in this study. Further research is needed to develop intervention strategies based on factors associated with non-adherence to COPD self-management.
