Frailty
ThemeCategorySample statements

TimeOlder age and aging processRisk for frailty is age-related and increases over time
Over age 80; greater than 65 years; “old-old”; fourth age
Aberrancies in biologic and physiologic systems lead to frailty
Gradual and unpredictable in the aging process
Progressive physiologic dysregulationAging and impaired homeostasis and defense mechanisms adversely impact function
Ambiguous boundaries and cause-effect relationships exist between morbidity, disability, and frailty
Progressive, time-dependent changes in structure and function
Dynamic trajectoryMalleable and may be prevented, mitigated, or reversed
Frailty usually worsens over time; slow dwindling dying trajectory
Transitional; constantly changing and evolving
Exists on a continuum from robust to end-of-life

RelationshipsBiopsychosocial domains of functionDomains are interrelated; mutually interacting and inextricably linked; adverse events in one domain impact the other domains
Frailty is used to classify people to prioritize care and health and social services
Frailty has many forms due to deficits in biopsychosocial domains of function
Blurred boundaries between frail and nonfrail state; distinctions between feeling frail and being frail
Quality of life and well-beingFrailty is a threat to emotional integration and wholeness
Frailty is associated with social isolation, weakened social position
Unstable social support or psychological states can precipitate or worsen frailty
Connections and interdependenceDependence/interdependence between social network, services, resources, technology
Transactional process requiring negotiation of interdependency and care receiving needs
Failed adaptation to manage frailty and changing biopsychosocial needs

LossPhysical function declineObservable frailty markers: weight loss, weakness, low energy, unstable balance, slow movement, and mobility aids
Accumulation of chronic diseases
Sensory losses in vision or hearing
Cascading pathway with negative consequencesLosses are exacerbated across biopsychosocial domains of function
Leads to impaired physical mobility and dependence
Falls, disability, hospitalization, institutionalization, quality of life, self-care deficits, early mortality
Psychological and social identityStigma and negative connotations and labeling as frailty erode self-esteem and threaten identity
Medical classification denies psychological and social aspects
Disempowerment; loss of autonomy, control, and inner drive

VulnerabilityImpaired resilienceReduced reserve capacity and ability to resist and overcome intrinsic and extrinsic stressors
Failing homeostasis and risk for adverse outcomes
Increased healthcare needs and utilization
Precarious stateInstability, uncertainty, fragility
Delicate balance and tipping point; fragility
Frailty precipitates increased healthcare needs and service utilization
Psychologic and social copingNegative emotional reactions to frailty; diminished autonomy
High psychological and social support needs; negatively impacted by social isolation, living alone
Antonym for successful aging
