Evaluation of frailty and influencing factors in old people in hospital institution: Evidence for a phenotype of frailty

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.
