Frailty and functional decline Flashcards

1
Q

What is frailty

A

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

Q

The role of the aging process in frailty

A

• 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

Q

Sarcopenia

A

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

Q

How frailty responds to stressors

A

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

Q

Consequences of frailty

A

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

Q

Scope and risk factors of frailty

A

• 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

Q

Why measure frailty

A
  • 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

Q

Why use a standardized tool to measure frailty

A
  • 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

Q

Canada’s population and acute care spending

A

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

Q

Screening for frailty

A

• 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

Q

Barriers to frailty screening: primary care

A
  • 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.

Q

Frailty screening: assisted living

A
  • 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

Q

Frailty screening: long-term homes

A
  • 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

Q

Frailty screening: acute care

A
  • 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

Q

Frailty screening: critical care

A
  • 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

Q

Assessment of frailty

A
  • Assessment – in-depth assessment to create a care plan
  • There is many frailty assessments (67 different tools found)

• Comprehensive Geriatric Assessment is the gold- standard in assessment (CGA)
• Unlikely to be adopted in low resource settings
• Frailty scales are often used as one part of a CGA to help clinicians hone in on areas that need more evaluation
- If you screen someone and they are frail; it is likely that you will follow up with a CGA

  • Social
  • Demographic
  • Economic
  • Environmental
20
Q

Social aspects of frailty

A

In Canadian studies:
• Lower social position (education and income) was strongly associated with frailty
• Living situation - alone
• social vulnerability correlated moderately with frailty, with both contributing independently to risk of death
• Low socioeconomic status
• Having few relatives and neighbours or little contact with
them
• Low participation in community or religious activities (social engagement)
• Low social support

An understanding of social circumstances is necessary to reduce social risk factors for poor health outcomes from frailty
• Overall social vulnerability is linked to cognitive decline and mortality - even among the fittest older people
• Health care providers need a comprehensive, organized understanding of social circumstances, available resources, and supports.
• These are key to planning care for people identified as frail, particularly in care transitions such as hospital discharge and in making decisions about care needs and residence

Q

Clinical scales

A

• 3 of the most commonly used frailty clinical scales in Canada:

  1. Frailty Phenotype – Fried, 2001
  2. Frailty Index (Deficit accumulation) – Rockwood
  3. Clinical Frailty Scale
25
Frailty phenotype model
5 elements 1) Weakness - grip strength (<20th percentile) 2) Slowness - walking time (15 feet), slowest 20% by sex and height 3) Low level of physical activity - bottom 20th percentile of calculated kcal 4) Exhaustion - self reported 5) Weight loss - >10% of unintentional weight loss during the prior year - Need 2 to be pre-frail - 3 or more is frailty
26
Frailty: accumulation of deficits
Frailty index = number of deficits in an individual / total number of potential deficits measured • A deficit = a thing that is “wrong” with you (sign, symptom, impairment; diseases, conditions, and co- morbidities) • The more deficits you have, the more likely you are to be frail - Index: scale used on a population/institutional level, more research based instead of clinical - Specific quantification of frailty
27
Clinical frailty scale (CFS)
- Most commonly used scale - Nine categories of frailty 1) Very fit 2) Well - no active disease symptoms, active occasionally 3) Managing well - medical problems are well controlled, not regularly active 4) Vulnerable - not dependant, symptoms limit activities 5) Mildly frail - more evident slowing, need help in higher order IADLs 6) Moderately frail - all outside activities help, help keeping house, help with bathing 7) Severely frail - completely dependent for personal care 8) Very severely frail - don't have resilience to bounce back from illness 9) Terminally ill - a life expectancy <6months, not otherwise evidently frail
28
Limitations of traditional frailty screening
• No consensus, different settings will use different tools • Infrequent assessment – usually after a big change, or upon entry into the HC system • Subject to subjectivity, memory loss – those with cognitive decline may not accurate report • Complex, requires clinician’s supervision – measurement of performances; based on clinical judgement • No home-based remote assessment
29
Frailty home sensor system and prediction
- Want to address the problem that there is no home based assessment of frailty ``` - Examine in home; Gait speed Muscle strength Weight loss Physical activity Exhaustion - Frailty statuses: frail, pre-frail, non-frail ```
30
Interventions for frailty
``` • Don’t bail on the frail • Four treatments appear to have potential to manage physical components of frailty: 1) Exercise 2) Caloric and protein support 3) Vitamin D 4) Reduction of polypharmacy ``` • Multicomponent interventions, and individually-tailored geriatric care models
31
Potential interventions along the spectrum of frailty in older adults
Robust - Symptom relief - Patient-centred goal setting - Family/caregiver support - Exercise - Interventions Increasingly frail - Exercise - Interventions - CGA and treatment - Geriatric evaluation and management (GEM) - Acute care for elders unit (ACE) - Program for all-inclusive care fo the elderly (PACE) End stage frailty - Hospice care - Comfort - Dignity
32
What is functional decline
- A new loss of independence in self-care capabilities - Associated with deterioration in mobility and in the performance of activities of daily living (ADLs) such as dressing, toileting, and bathing
33
Age-related changes associated with functional decline
* Decline in muscle strength and aerobic capacity * Vasomotor instability * Reduced bone density * Diminished pulmonary ventilation * Altered sensory “continence”, appetite and thirst * A tendency toward urinary incontinence
34
Risk factors for functional decline
* Age * Cognitive status * Depression * Lifestyle factors such as inactivity
35
Concepts related to functional decline
* Disuse muscle atrophy – reduction in muscle mass and strength caused by muscle inactivity or disuse * Functional mobility decline: the capacity to execute safe, efficient walking (with or without a gait aid) within the environmental constraints encountered in everyday life - Functional decline; ability to do ADL in general - Functional ability; ability to get up from chair and walk the distance - adds to functional decline
36
Muscle atrophy
- Degradation of muscle | - "if you don't use it, you lose it"
37
Functional decline in acute care: how dangerous is it
- High up on lives lost per year vs. encounters per death - Close to that of driving ``` Other adverse and cascading consequences: • Delirium+ deconditioning • Increased LOS • Progressive functional decline • Re-admission • ALC • Institutionalization ```
38
Functional decline related to hospitalization
“It is common but not inevitable.” • Functional decline may occur a few days before hospitalization as a consequence of the acute medical illness • Functional losses can occur as early as the second day of hospitalization • 30-60% experience functional decline resulting in more dependency in ADLs and other adverse events • After hospital admission, approximately 20% experience significant functional improvement during their hospital stay • Deconditioning contributed to delayed discharge in more than 47% of older adult patients • At least 30% of patients ≥ 70 years old are discharged with an ADL disability they did not have before becoming acutely ill - Hospitalization-associated disability: During hospitalization, the acute medical issues are treated. However, the patient is discharged with a major new disability that was not present before the onset of acute illness • One year after discharge, fewer than half will recover to the pre-illness level of function.
39
Complications of hospitalization
``` Delirium: 25-60% Functional decline: 34-50% Adverse drug event: 54% Surgical complications: 52% Diagnostic and therapeutic mishap: 31% Nosocomial infections: 17% Physical injury/fall: 15% Pressure sores: 10% Pulmonary embolism: 3% ```
40
Care related factors that contribute to functional decline in hospitals
• Bedrest orders; consequences of Bedrest Table • Physical restraints • Mobility restricting devices; indwelling catheters, IVs, chest tubes • Insufficient nutrition and hydration; NPO (no food by mouth) orders; diet not preferred by the patient; new texture of food; inadequate access to water and fluids • Deconditioning; Decreased participation in own ADLS • Polypharmacy; new medications that can influence activity or mobility (e.g. sleep medications, pain medications, anti-depressives) • Late discharge planning
41
Behavioural and physical environmental factors that contribute to functional decline in hospital
* Social deprivation – socially isolated * Physical environment does not encourage mobility – cluttered, high beds, rails, meals served in bed; furniture on wheels, no handrails in rooms * Environment contributes to disorientation – can’t see the clock, no calendar in the room, lighting does not match time of day; shiny floors that cause glare = falls; noisy environment which disrupts sleep * Sensory deprivation – lost or broken hearing aid or glasses
42
Identification of seniors at risk; hospitalized patients (ISAR-HP)
The ISAR-HP is a recently developed screening instrument to predict 90- day functional decline in older patients who were acutely admitted to the department of internal medicine • Nurses should assess needs and risks to initiate interventions that can prevent functional decline • 4 different questions that assess needs and risks 1) Before hospital admission, did you need assistance for IADL on regular basis? 2) Do you use a walking device? 3) Do you need assistance for travelling 4) Did you pursue education after age 14? - Each score gets 1 or 0 - Total score 0 or 1 = not at risk - Total score >2 = patient is at risk for functional decline
43
Mobilization and exercise for functional decline
- Overall found a significant decline in all three functional mobility measures over a 2- months of usual care - Participation in a person-centred walking intervention reduced functional mobility decline and led to improvement - Participants were able to regain what they lost in the control period - Participants had improved scores after the MWI compared to baseline **knowing information and applying it to you patient can reduce functional decline**
44
Can we manage frailty and functional decline better?
• Can we mitigate the impact of hospitalization? - Yes: Senior Friendly Hospitals (SFH) • Can we prevent rehospitalization? - Yes: better discharge planning and transitional care • Can hospitalization be avoided in the first place? - Yes: interdisciplinary, Comprehensive Geriatric Assessment (CGA), including in primary care • Does Nursing have a role to play in the prevention of hospital aquired disability? - Yes. Assessment, advocacy, daily care to preventing deconditioning; person- centered care
