Abstract：This study aimed to systematically define the concept of“new⁃onset disability in older adults”
using Rodgers’evolutionary concept analysis approach. Through a systematic literature search in both Chinese
and international databases，34 articles were included for analysis. Five core attributes of new⁃onset disability in
older adults were identified: sudden functional disruption，vulnerability in psychological adaptation，uncertainty
of rehabilitation trajectories，discontinuity of caregiving resources，and time ⁃ sensitive nature of rehabilitation
interventions. A conceptual framework was developed integrating multilevel antecedents（individual，family，
community，societal）and multidimensional outcomes（physical，psychological，social）. A representative case was
used to validate the recognizability and clinical applicability of this concept，revealing that the target population
is situated in a critical transition period from functional independence to dependence，with substantial potential
for recovery and intervention. This study fills a theoretical gap in the current literature and provides a scientific
foundation for early identification，evidence ⁃ based intervention，and the optimization of health management
strategies tailored to this high⁃risk aging population.
