| Sumario: | The objectives of this study were: to describe the sociodemographic, clinical, health and functional capacity characteristics of the elderly; calculate the prevalence of frailty and describe its changes; to verify the predictors of frailty conditions and frailty phenotype (FF) components after four years of hospital discharge; verify the impairment of FF components as predictors of frailty conditions at follow-up; evaluate the condition of frailty as a predictor of increased readmissions and readmissions as a predictor of the condition of frailty; determine the association between frailty and mortality; and components of FF and mortality; and evaluate the condition of frailty as a predictor of quality of life at follow-up. Longitudinal survey with 99 elderly who completed the four-year follow-up. Were used: form for characterization of sociodemographic, economic and health data; Mini Mental State Examination; Scales (Geriatric Depression shortened, Katz, Lawton and Brody); World Health Organization Quality of Life - Bref, World Health Organization Quality of Life Assessment for Older Adults and FF. We proceeded to the descriptive analysis, Chi-square, Cochrane and McNemar tests; ANOVA; and binary, multiple, linear and multivariate Cox logistic regression models (p<0.05); and Kaplan-Meier survival. A higher prevalence of prefrail elderly individuals was identified, followed by non- frail and frail during the follow-ups. After four years of discharge there was an increase in frail elderly; and decrease in pre- frail and non- frail. Regardless of follow-up, there were higher percentages of non-frail elderly who changed to pre- frail, followed by frail to pre- frail; and death in the frail. Increased scores of the indicative for depression was a predictor of pre-frail and frail condition; while increasing the number of medications and decreasing IADL scores for the frail condition. Increased number of medications and decreased scores of IADL were predictors of decreased muscle strength; increased scores of the indicative for depression for self- reported exhaustion and/or fatigue and low level of physical activity; and the decrease in IADL scores on self-reported exhaustion and/or fatigue, slow walking speed and low level of physical activity. Exhaustion and/or fatigue self- report was a predictor for pre- frail and frail elderly; and decreased muscle strength for the frail. The condition of frailty was not a predictor of readmissions. However, the increase in readmissions was a predictor of the frail condition at follow-up. After four years of hospital discharge, the frail and pre-frail conditions were predictors of death, and the same occurred in elderly with slow walking speed, decreased muscle strength, self-reported exhaustion and/or fatigue, and low physical activity. The frail conditio n was associated with lower QoL scores, after four years of hospital discharge, in the physical and environmental domains; and facets autonomy, past, present and future activities and social participation. In the pre-frail condition, lower scores were identified in the facets autonomy and social participation. The results of this investigation may help in identifying the elderly groups that need early interventions, so that there is improvement and/or staging of frailty. |
