Relationship between frailty, physical performance and quality of life among nursing home residents: the SENIOR cohort

ABSTRACT

Background:
The aim of this study was to assess the relationship between frailty and a large number of indicators related to physical and muscular performance as well as quality of life.
Methods:
This is an analysis of data collected at baseline in the Sample of Elderly Nursing home Individuals: an Observational Research (SENIOR) cohort including nursing home residents. Subjects are volunteer, oriented and able to walk (walking assistance allowed) nursing home residents in Belgium. A large number of demographic and clinical characteristics, including physical and muscular performance, were collected from each patient. The prevalence of frailty in this population was assessed using Fried’s definition.
Results:
In total, 662 subjects are included in this analysis. The mean age of the sample is 83.2 ± 8.99 years, and 484 (73.1 %) are women. In this population of nursing home residents, the prevalence of frailty is 25.1 %, pre-frailty, 59.8 % and robustness, 15.1 %. Compared to non-frail subjects, frail subjects have lower physical and muscular performances and a lower quality of life.
Conclusion:
Frailty, according to Fried’s definition, seems to be associated with several clinical indicators suggesting a higher level of disability and an increased propensity to develop major clinical consequences. Follow-up data of the SENIOR cohort will be helpful in confirming these findings, establishing cause-effect relationships and identifying the most predictive components of physical frailty for adverse outcomes in nursing homes.
