Postoperative Frailty Trajectories and One-Year Mortality in Older Surgical Patients

China4,417 participantsStarted 2020-04-01

Plain-language summary

Frailty is a key predictor of adverse outcomes in older surgical patients, yet its longitudinal evolution and potentially reversible nature remain underexplored in perioperative settings. This study aimed to characterize postoperative frailty trajectories in older patients and to examine their association with one-year mortality, as well as factors influencing trajectory group.
