Frailty Transitions in Older Persons With Lung Function Impairment: A Population-Based Study

Area of Science:

• Gerontology
• Pulmonology
• Clinical Medicine

Background:

• Aging populations increase healthcare burdens, necessitating early identification of individuals at risk for functional decline and mortality.
• Impaired spirometry, including Preserved Ratio Impaired Spirometry (PRISm) and chronic obstructive pulmonary disease (COPD), is common in older adults.
• Frailty is a key indicator of health status and a predictor of adverse outcomes in aging populations.

Purpose of the Study:

• To evaluate frailty transitions in individuals with impaired spirometry (PRISm or COPD).
• To assess the accuracy of frailty scoring for predicting mortality in patients with COPD.
• To understand the relationship between lung function impairment and the progression or recovery of frailty states.

Main Methods:

• Analysis of data from the population-based Rotterdam Study (mean age 69.1 years).
• Utilized multinomial regression models to examine frailty transitions (robust, prefrailty, frailty, death) in relation to PRISm and COPD status.
• Assessed the diagnostic accuracy of a frailty score for mortality prediction in COPD participants using c-statistics.

Main Results:

• Participants with PRISm were more likely to progress to frailty from robust or prefrailty states.
• Both PRISm and COPD were associated with reduced recovery from frailty and increased progression towards death.
• Adding a frailty score to traditional risk factors significantly improved mortality prediction accuracy in COPD patients (90.5% vs 77.9%).

Conclusions:

• Impaired spirometry (PRISm, COPD) is linked to increased frailty development and poorer reversibility.
• Physical frailty assessment improves risk stratification for mortality in individuals with impaired lung function.
• Early detection and management of frailty in patients with spirometry impairments can potentially improve life expectancy.
