The Use of Figurative Language to Describe Frailty in Older Adults

INTRODUCTION

Frailty affects 15% of non-institutionalized older adults in the United States, yet confusion remains in defining and, in turn, assessing frailty. Figurative language, such as metaphor, can help to explain difficult scientific concepts and to form new theories. We aimed to examine the use of figurative language to describe frailty and to identify themes in the way figurative expressions are used. Understanding how frailty is described figuratively may offer insights for developing useful communication approaches in research settings.

METHODS

We performed a comprehensive review of editorials in the scientific literature to explore figurative language used to describe frailty in older adults. We categorized themes among the figurative expressions, which may help to inform how to effectively communicate about frailty.

RESULTS

We found 24 editorials containing 32 figurative expressions. The figurative expressions conceptualized frailty in six ways: 1) a complex, multifaceted concept; 2) an important issue in health and medicine; 3) indicative of something that is failing or faulty; 4) indicative of fragility; 5) representative of vulnerable, ignored persons; and 6) an opportunity for self-awareness and reflection.

DISCUSSION

Our review highlights the heterogeneity in depictions of frailty, which is consonant with the lack of a standardized definition of frailty. We also found a novel aspect to the concept of frailty, which merits attention: frailty characterized as an opportunity for self-awareness and reflection. Figurative language, which often juxtaposes familiar with challenging, complex concepts, can offer insights on issues in frailty research and holds potential as a tool for researchers to improve communication about this important and debated medical condition.

An Empirical Comparison of the EQ-5D-5L, DEMQOL-U and DEMQOL-Proxy-U in a Post-Hospitalisation Population of Frail Older People Living in Residential Aged Care

OBJECTIVE

To empirically compare the measurement properties of the DEMQOL-U and DEMQOL-Proxy-U instruments to the EQ-5D-5L and its proxy version (CEQ-5D-5L) in a population of frail older people living in residential aged care in the post-hospitalisation period following a hip fracture.

METHODS

A battery of instruments to measure health-related quality of life (HRQoL), cognition, and clinical indicators of depression, pain and functioning were administered at baseline and repeated at 4 weeks' follow-up. Descriptive summary statistics were produced and psychometric analyses were conducted to assess the levels of agreement, convergent validity and known group validity between clinical indicators and HRQoL measures.

RESULTS

There was a large divergence in mean (SD) utility scores at baseline for the EQ-5D-5L and DEMQOL-U [EQ-5D-5L mean 0.21 (0.19); DEMQOL-U mean 0.79 (0.14)]. At 4 weeks' follow-up, there was a marked improvement in EQ-5D-5L scores whereas DEMQOL-U scores had deteriorated. [EQ-5D-5L mean 0.45 (0.38); DEMQOL-U mean 0.58 (0.38)]. The EQ-5D and CEQ-5D-5L were more responsive to the physical recovery trajectory experienced by frail older people following surgery to repair a fractured hip, whereas the DEMQOL-U and DEMQOL-Proxy-U appeared more responsive to the changes in delirium and dementia symptoms often experienced by frail older people in this period.

CONCLUSIONS

This study presents important insights into the HRQoL of a relatively under-researched population of post-hospitalisation frail older people in residential care. Further research should investigate the implications for economic evaluation of self-complete versus proxy assessment of HRQoL and the choice of preference-based instrument for the measurement and valuation of HRQoL in older people exhibiting cognitive decline, dementia and other co-morbidities.

How important is health status in defining quality of life for older people? An exploratory study of the views of older South Australians

BACKGROUND

Cost-effectiveness analyses of interventions for older adults have traditionally focused on health status. However, there is increasing recognition of the need to develop new instruments to capture quality of life in a broader sense in the face of age-associated increasing frailty and declining health status, particularly in the economic evaluation of aged and social care interventions that may have positive benefits beyond health.

OBJECTIVE

To explore the relative importance of health and broader quality of life domains for defining quality of life from the perspective of older South Australians.

METHODS

Older adults (n=21) from a day rehabilitation facility in Southern Adelaide, South Australia attended one of two audio-recorded focus groups. A mixed methods (qualitative and quantitative) study design was adopted. The study included three main components. First was a general group discussion on quality of life and the factors of importance in defining quality of life. Second was a structured ranking exercise in which individuals were asked to rank domains from the brief Older People's Quality of Life (OPQOL-brief) questionnaire and Adult Social Care Outcomes Toolkit (ASCOT) in order of importance. Third, participants were asked to self-complete the EuroQol five-dimension (EQ-5D), a measure of health status, and two broader quality-of-life measures: the OPQOL-brief and ASCOT.

RESULTS

Mean scores on the EQ-5D, OPQOL-brief and ASCOT were 0.71 (standard deviation [SD] 0.20, range 0.06-1.00), 54.6 (SD 5.5, range 38-61) and 0.87 (SD 0.13, range 0.59-1.00), respectively, with higher scores reflecting better ratings. EQ-5D scores were positively associated with OPQOL-brief (Spearman's Rho: 0.730; p<0.01), but not ASCOT. Approximately half (52.4%) of the participants ranked either 'health' or 'psychological and emotional well-being' as the domain most important to their quality of life. However, one-third (33.3%) of the total sample ranked a non-health domain from the ASCOT or OPQOL-brief (safety, dignity, independence) as the most important contributing factor to their overall quality of life. Qualitative analysis of focus group transcripts supported the high value of both health-related (health, psychological well-being) and social (independence, safety) domains to quality of life.

CONCLUSIONS

Older adults value both health and social domains as important to their overall quality of life. Future economic evaluations of health, community and aged-care services for older adults should include assessment of both health-related and broader aspects of quality of life.
