Physical frailty characteristics have a differential impact on symptoms as measured by the CAT score: an observational study.

Background: The physical frailty status affects the health status of patients with chronic obstructive pulmonary disease (COPD). The objective was to determine if the individual physical frailty characteristics have a differential impact on the CAT score.

Methods: This observational study included 137 patients with stable COPD.

Patterns and predictors of exhaustion episodes in patients with stable COPD: A longitudinal study.

Background And Objective: Exhaustion is the perception of low energy. Little is known about how exhaustion persists, remits or reappears over time in patients with chronic obstructive pulmonary disease (COPD) or how to predict these events. We determined the likelihood of transitions between states of exhaustion and no exhaustion among patients with stable COPD followed up for 2 years.

Determinants of each domain of the Short Physical Performance Battery in COPD.

Background: The Short Physical Performance Battery (SPPB) is an assessment tool with good prognostic value in COPD. It includes the following: standing balance, 4 m gait speed test (4MGS), and the timed five-repetition sit-to-stand test (5STS). The specific differences in determinants between these three tasks have not been adequately characterized in COPD patients.

Frailty is a predictive factor of readmission within 90 days of hospitalization for acute exacerbations of chronic obstructive pulmonary disease: a longitudinal study.

Background: Readmission after hospital discharge is common in patients with acute exacerbations (AE) of chronic obstructive pulmonary disease (COPD). Although frailty predicts hospital readmission in patients with chronic nonpulmonary diseases, no multidimensional frailty measures have been validated to stratify the risk for patients with COPD.

Aim: The aim of this study was to explore multidimensional frailty as a potential risk factor for readmission due to a new exacerbation episode during the 90 days after hospitalization for AE-COPD and to test whether frailty could improve the identification of patients at high risk of readmission.

The Short Physical Performance Battery is a discriminative tool for identifying patients with COPD at risk of disability.

Background: Limited mobility is a risk factor for developing chronic obstructive pulmonary disease (COPD)-related disabilities. Little is known about the validity of the Short Physical Performance Battery (SPPB) for identifying mobility limitations in patients with COPD.

Objective: To determine the clinical validity of the SPPB summary score and its three components (standing balance, 4-meter gait speed, and five-repetition sit-to-stand) for identifying mobility limitations in patients with COPD.
