Frailty and mortality: an 18-year follow-up study among Finnish community-dwelling older people.

ABSTRACT: BACKGROUND:There is a lack of agreement about applicable instrument to screen frailty in clinical settings. AIMS:To analyze the association between frailty and mortality in Finnish community-dwelling older people. METHODS:This was a prospective study with 10- and 18-year follow-ups. Frailty was assessed using FRAIL scale (FS) (n = 1152), Rockwood's frailty index (FI) (n = 1126), and PRISMA-7 (n = 1124). To analyze the association between frailty and mortality, Cox regression model was used. RESULTS:Prevalence of frailty varied from 2 to 24% based on the index used. In unadjusted models, frailty was associated with higher mortality according to FS (hazard ratio 7.96 [95% confidence interval 5.10-12.41] in 10-year follow-up, and 6.32 [4.17-9.57] in 18-year follow-up) and FI (5.97 [4.13-8.64]
