Determinants of Medication Nonadherence Among Diverse Adults With Chronic Obstructive Pulmonary Disease.

ABSTRACT:

Introduction

High rates of medication nonadherence contribute to poor outcomes in chronic obstructive pulmonary disease (COPD), but the mechanisms driving nonadherence remain poorly understood.

Participants overcame these barriers by requesting more affordable inhalers, keeping inhalers in strategic locations, routinizing inhaler use,
