Frailty and functional decline Flashcards
What is frailty
Risk of death increases with age, but not everyone of the same age has the same risk of dying. This observation led to the concept of frailty.
- Clinical frailty can occur at any age; frailty most often occurs in people older than 65 years
- Frailty is distinct but overlapping with both disability and comorbidity/multi- morbidity
NO DEFINITION
- Manifested as a loss of function and increased risk of inability to maintain homeostasis (e.g. function as a person)
- People at a particular age who, in consequence of multisystem impairments, are at higher risk of dying are said to be frail while those at lower risk are said to be fit
- A physiologic syndrome characterized by decreased reserve and resistance to stressors, resulting from cumulative decline across multiple physiologic systems, and causing vulnerability to adverse outcomes
The role of the aging process in frailty
• Sarcopenia - the age-related loss of skeletal muscle mass and function
• Decline in the functioning of endocrine system • Low level of chronic inflammation secondary
to age-related dysregulation of the immune system
Sarcopenia
Age-related changes to skeletal muscle; the progressive loss of skeletal muscle mass, strength and function that further contributes to mobility impairments and disability.
- Sarcopenia is therefore a marker of frailty
- Muscle mass can continue to build until a person is in their 50’s. However, between 30% and 50% of the skeletal muscle mass of a 30 year old may be lost by the time the person reaches their 90’s; disuse of muscles accelerates the loss of strength
- Risk factors: age, gender, levels of physical exercise, protein-calorie malnutrition
- Physical activity, particularly strength training and adequate intake of energy and protein can prevent or reverse sarcopenia
How frailty responds to stressors
Managing well
- External stressor (e.g. minor illness or injury)
- Resilience and ability to bounce back to baseline
Mild frailty
- Increased vulnerability to those who are frail
- Hard to go back to their previous state
Severe frailty
- Takes much longer to recover and after they could be at level that they are no longe4r independent
Consequences of frailty
Frailty is crucial because it can lead to adverse health outcomes:
• Disability
• Death
• Hospitalization
• Risk of iatrogenic disability which is defined as the avoidable dependence which often occurs during the course of care
Increasing frailty was associated with:
• A 4 times increased 5-year risk for death among mildly frail people and 7 times increase among severely frail people.
• Frailty was the most important predictor of institutionalization
Scope and risk factors of frailty
• Very common; hallmark of geriatric syndromes
- Frailty is a geriatric syndrome, but it can also cause other geriatric syndromes
• Community-dwelling older adults varies from 4.0% to 59.1%
- Increases with age
- Greater in women than in men
- Lower education and income,
- poorer health and high rates of co-morbid conditions
Older Canadians living with frailty
- 25% over 65
- 50% over 85
- That more than 1 million Canadians
- In 10 years, expected to be 2 million
Why measure frailty
- It informs clinical decision-making
- Failure to detect frailty potentially exposes patients to interventions from which they might not benefit or indeed be harmed
- Conversely, exclusion of non-frail elderly people merely on the basis of age is unacceptable
- FRAILTY IS ASSESSED, NOT ASSUMED
Why use a standardized tool to measure frailty
- To allow early identification of older adults at risk of geriatric syndromes and adverse outcomes to start interventions
- Common language
- Global assessment of functioning
- Ability to monitor changes over time
- The use of a short frailty screen allows selection of older adults that can undergo further assessment, comprehensive geriatric assessment
Canada’s population and acute care spending
Adults aged 65+
- 16.8% of population
- 60% of hospital spending
- Tend to use more money on older people because out healthcare system is not designed to look at people who have multi-system diseases
- Also at greater risks once hospitalized for other infections
Screening for frailty
• Screening – identifying those at risk; does not provide specific information. Indicates whether an assessment should be done
Occurs in three contexts:
(1) for specific populations – oncology, cardiology
(2) at times of unanticipated health care needs such as in emergency departments or pre-hospital care
(3) before elective procedures
How screening for frailty works
Categories (for older adults)
- Fit
- Pre-frail
- Mild/moderate frailty
- Severe/very severe frailty
1) Frailty case finding
2) Classification
3) Comprehensive assessment
4) Integrated care; individualized patient-centred care
- Medication
- Medical issues
- Physical capabilities
- Functional capabilities
- Psychological capabilities
- Social factors
- Environmental factors
Barriers to frailty screening: primary care
- Ideally situated to screen
- But often mistake frailty as “normal signs of aging”
- Risk factors like dementia are under recognized
- Most tools rely on self-reported deficits of function and health
- No consensus on tools.
Frailty screening: assisted living
- Protective environment that can offer increased supervision and assistance with activities of daily living
- High levels of cognitive and physical impairment found in this population
- Performance-based frailty criteria such as gait speed and grip strength can be difficult to measure
Frailty screening: long-term homes
- Residents are a frail or potentially frail group of vulnerable older adults and focus on preserving and enhancing quality of life in very late life
Screening can:
1) identify frailty or to serve as catalyst to measure its severity, or
2) support advance care planning. There are specific tools for the nursing home population
- Use of EMR data to detect frailty using predictive models
- Highest rates of frailty found in nursing homes; 24Hr supervision, focus on quality of live as opposed to interventions
Frailty screening: acute care
- Small proportion of OAs are high users of acute care services
- Those users tend to have multiple chronic conditions, at least one functional impairment, and inadequate social supports at home
• Almost half experience a decline in their functional abilities in the weeks before their admission
• Frailty screening in ER, prior to surgery - Screening should not be used in isolation but rather should be embedded in proactive systems of care that support immediate action
Frailty screening: critical care
- Frailty among people admitted to intensive care units has had little evaluation
• Frail people were more likely to suffer adverse events and have longer stays in ICU and hospital. Their probability of in-hospital death was almost double that of non-frail people.
• Much is unknown about frailty in the ICU
