Comparison of Two Frailty Assessment Methods and Their Association with Functionality in Subjects with Exacerbation of COPD.

Objectives: To verify the prevalence of frailty in patients hospitalized with acute exacerbation of COPD; to compare two frailty assessment methods: Edmonton Scale and the Fried Frailty Phenotype, and to associate frailty with functioning in these patients.

Methods: Patients hospitalized due to an acute exacerbation of COPD were included. The assessment of pulmonary function, frailty, and functioning was performed.
