Association of frailty Trajectories with Medical and Long-Term Care Costs
Description: Using up to 12 years of repeated-measures data, we identified aging trajectories for an index in frailty score among older Japanese and examined whether these trajectories were associated with all-cause mortality and healthcare costs. The total number of observations was 6373. Frailty was defined by criteria from Fried’s phenotype. We identified four aging trajectories for frailty. Specifically, 6.5%, 47.3%, 30.3%, and 16.0% of participants were in the high, second, third, and low trajectory groups, respectively. As compared with the low trajectory group, the high trajectory group had greater risks of death. Medical and long-term care costs greatly increased after age 80 years in the second and third trajectory groups. Medical and care needs greatly increased for the second and third trajectory groups when they progressed from pre-frailty to frailty.
