Clinical Severity, Multidimensional Assessment, and Functional Impairment in COPD Patients Undergoing Specialized Functional-Capacity Assessment

Background/Objectives: Chronic obstructive pulmonary disease (COPD) causes functional consequences that may not be fully captured by conventional measures of disease severity.

Methods

This retrospective cross-sectional study explored associations between clinical-functional characteristics and limitations in activities of daily living (ADL) among 184 patients with COPD undergoing specialized functional-capacity evaluation. Associations of clinical severity, forced expiratory volume in one second (FEV1), dyspnea, exercise capacity, and the BODE index with ADL limitation were evaluated using multivariable ordinal regression models.
