Evaluation of frailty and influencing factors in old people in hospital institution

We assessed the frailty status of inpatients and analyzed the factors influencing frailty status to explore the reasons for frailty and identify feasible intervention strategies.A total of 1494 geriatric patients aged ≥60 years were recruited as subjects. All patients were hospitalized between September 2014 and August 2015 in the internal medicine units of 3 hospitals in Chongqing and Zunyi in the southwestern area of China. Patients' frailty status was evaluated using the Phenotype of Frailty scale, via face-to-face interviews coupled with physical examinations using simple equipment.Of the 1494 cases, 1400 (93.71%) were eligible for analysis. Participants' mean age was 75.52 ± 9.28 years. The overall prevalence of frailty was 18.0%, and was higher for frail females (9.4%) than males (8.6%). Increasing age and body mass index, low income (<1000 Ren Min Bi for per month), poor self-rated health, cognitive impairment, depression, polypharmacy (≥5 medications), disability, and a history of fall in the past 1 year were independently significantly correlated with frailty (P < .05 for each comparison).Numerous factors were associated with frailty. As treatment for frailty is focused on prevention in this study, intervention strategies should target a comprehensive list of physiological and psychological aspects of the older people.
