FS often coexists with chronic diseases. It increases the risk of adverse health events and is strongly associated with a decrease in mobility, an increased risk of falls, polypharmacy, comorbidities, a decrease in cognitive function, and malnutrition.8 On the one hand, FS can be regarded as a consequence of aging, but on the other, it is associated with many chronic diseases that increase patient disability, hospitalization rates, costs of health care, and mortality. To date, frailty has been assessed in patients with many chronic diseases, such as cardiovascular diseases, obesity, renal insufficiency, but little is known about the coexistence of frailty with COPD in elderly patients.8–11 Moreover, the impact of FS on the acceptance of illness in elderly COPD patients remains unclear.
