Physical, Psychological and Social Frailty in Prediction of Disability and Quality of Life

Association between physical, psychological and social frailty and health-related quality of life among older people

BACKGROUND

Studies on the association between frailty and health-related quality of life (HRQoL) are scarce and show contradictory results. This study aimed to evaluate the association between physical, psychological and social frailty and HRQoL among community-dwelling older people.

METHODS

A cross-sectional study was performed with baseline data collected in 2015 from the Urban Health Centers Europe (UHCE) project in five European countries, the United Kingdom, Greece, Croatia, The Netherlands and Spain. A total of 2325 participants were included in the baseline measurements of the Urban Health Centers Europe project; 2167 participants (mean age = 79.7; SD=5.6) were included in the analyses after excluding participants with missing data. The Tilburg Frailty Indicator measured overall frailty as well as physical, psychological and social frailty. The 12-Item Short-Form Health Survey was used to measured physical and mental HRQoL.

RESULTS

Regarding physical HRQoL, a large difference (d=1.29) between physically and not physically frail participants was observed. Regarding mental HRQoL, a large difference (d=1.20) between psychologically and not psychologically frail participants was observed. In the full model with all three domains of frailty and the covariates to explain physical HRQoL, physical (P <0.001) and social frailty (P <0.001) remained significant. In the full model to explain mental HRQoL, all three domains of frailty remained significant (P <0.001).

CONCLUSION

Physical frailty had the strongest association with physical HRQoL, and psychological frailty had the strongest association with mental HRQoL. The associations between social frailty and both physical and mental HRQoL remain significant when controlling for physical and psychological frailty.

Combating frailty and sarcopenia in aging populations: Switching to a more positive paradigm

Frailty may be used as a public health indicator of aging well for projection of health and social care resource allocation. Frailty assessments have been adopted by various medical as well as surgical specialties as part of prognosis in influencing choice of therapy, although the assessment tools are even more heterogeneous than those in the gerontological fields. Recently, the World Health Organization called for a life course approach to healthy aging, placing the emphasis on function, expressed as intrinsic capacity, which would address concerns with the negative image of frailty and with the overemphasis on deficits. The impact of social and physical environments is taken into account in the concept of resilience. These are all related concepts that differ in the setting in which they are used. Frailty may be more useful in clinical management in hospitals and residential care homes, as well as in community models of care. Intrinsic capacity could be used for development of health-promotion policies and service models across the life course; mainly primary care with low resource needs, using a step-care approach. Resilience could be considered an overarching holistic concept covering physical, psychological, and environmental domains, which is still in the research arena.

[Explaining discrepancies in self-reported quality of life in frail older people: a mixed-methods study]

Most research on (multidimensional) frailty focuses on deficits and risks of adverse outcomes. However, frail older people can still report positive outcomes, such as a relatively high QoL. In order to develop more positively oriented prevention strategies, this exploratory study aimed (a) to identify characteristics related to QoL among frail older people; and (b) to explain discrepancies between higher and lower levels of QoL, with a specific focus on strengths frail older people with a higher QoL still may have. Quantitative and qualitative data was gathered by means of semi-structured interviews with Flemish community-dwelling, frail older people with higher (n = 16) and lower QoL levels (n = 18). Quantitative analyses showed that frail older people with a higher QoL were older, had lower levels of psychological frailty, and reported higher meaning in life compared to those with a lower QoL. Outcomes of qualitative analysis showed that participants in the high QoL subgroup adapted more effectively to difficulties, had more things in prospect, performed more activities, and were more satisfied with their social network compared to the low QoL subgroup. To conclude, this exploratory study suggests possibilities to promote and improve QoL by strengthening specific resources among frail older people.Please note that an English version of this article has been published in BMC Geriatrics: van der Vorst A, Zijlstra GAR, De Witte N, Vogel RGM, Schols JMGA, Kempen GIJM, D‑SCOPE Consortium.

Explaining discrepancies in self-reported quality of life in frail older people: a mixed-methods study

Background

Most research on multidimensional frailty focuses on deficits and risks of adverse outcomes. However, although some frail older people report a low quality of life (QoL), others still report a relatively high QoL. More knowledge about these discrepancies might give new insight into developing frailty prevention strategies. Therefore, this mixed-method study aimed (a) to identify characteristics related to QoL among frail older people; and (b) to explain discrepancies between higher and lower levels of QoL, with a specific interest in identifying strengths frail older people with a higher QoL still have.

Methods

Semi-structured interviews were held with community-dwelling, frail older people with higher (n = 16) and lower levels of QoL (n = 18). Frailty was assessed with the Comprehensive Frailty Assessment Instrument, which measures environmental, physical, psychological, and social frailty. Other quantitative measures included socio-demographic characteristics, overall QoL, meaning in life, and mastery. The qualitative part focused on the meaning and maintenance of QoL (among other factors), despite being frail. Possible explanations for discrepancies in QoL were explored.

Results

Frail older people with a higher QoL were older, had lower levels of psychological frailty, and reported higher meaning in life compared to those with a lower QoL. Outcomes of qualitative analysis showed that participants in the high QoL subgroup adapted more effectively to difficulties, had more things in prospect, performed more activities, and were more satisfied with their social network compared to the low QoL subgroup.

Conclusion

This exploratory study suggests possibilities to promote and improve QoL by strengthening specific resources among frail older people.
