FRAIL ELDERLY PATHWAY AND FRAILTY IN THE ELDERLY
Dr. M. Ganeshananthan
Problem
Increasing numbers of frail older people are attending the Emergency Department
Frail older people have the highest ‘conversion rate’
High risk of adverse events Long stays High readmission rates High rates of long term care
Solutions
Generic interventions Better access to health care systems Better communication
Specific pathways for frail older people Based on comprehensive geriatric
assessment Outlined national policy documents
Frail Elderly Pathway
Aim- Integrated pathway for frail elderly patients Incorporating acute hospital care, community
care social care and old age psychiatry Objectives
Enhance health of frail older people Reduce unnecessary emergency admissions Reduce the need for long term institutional
care
Frail Elderly Pathway
Maintaining independence
Choosing to admit (Enhanced rapid assessment in ED/MAU and in the community)
Discharging to assess(Supported early discharge for complex frail elderly patients)
Frail Elderly Pathway
The pathway is delivered by:
Two geriatriciansIDT/OPALICT in the communityPart time community psychiatristDay assessment centre at MilfordRapid Response clinic
Frail Elderly Pathway
How do we deliver this service in the acute setting?
Comprehensive Geriatric Assessment (CGA)
What is GCA?
CGA
‘Multidimensional, interdisciplinary diagnostic process to determine the medical, psychological, and functional capabilities of a frail older person in order to develop a coordinated and integrated plan for treatment and long-term follow-up
CGA
‘Multidimensional, interdisciplinary diagnostic process to determine the medical, psychological, and functional capabilities of a frail older person in order to develop a coordinated and integrated plan for treatment and long-term follow-up
CGA- Evidence
Improves outcomes of older people in various settings
Reduced mortality or deterioration Improved cognition Improved quality of life Reduced length of stay Reduced readmission rates Reduced rates of long term care use Reduced costs
CGA
The main domains of CGA
Medical Mental health Functional capacity Social circumstances Environment
Frailty
The condition of being weak and delicate: the increasing frailty of old age
(weakness in character or morals: all drama begins with human frailty)
Who is frail?
Frailty
Syndrome which results from a multisystem reduction in reserve capacity to the extent that a number of physiological systems are close to or past the threshold of symptomatic failure
Increased risk of disability or death from minor external stresses
Frailty
Frailty
Small insult results in a striking and disproportionate change in health state
Independent to dependent Mobile to immobile Postural stability to proneness to falling Lucid to delirious
Frailty
Distinct syndrome
Growing old is not in itself a prerequisite to becoming frail
A disability does not lead to frailty in a robust older person
Clinical presentations
Non-specific
Extreme fatigue Unexplained weight loss Frequent infections
Falls Due to gait and balance impairment Hot fall
Clinical presentations
Delirium
Due to reduced integrity of the brain function
Independently associated with adverse outcome
Fluctuating disability Day-to-day instability
Pathophysiology
Normal ageing Gradual decrease in physiological reserve
Frailty Accelerated Homoeostatic mechanisms start to fail
Pathophysiology
Cumulative decline in several physiological systems
Determined by genetic and environmental factors
Loss of physiological reserve of the brain, endocrine system, immune system and skeletal muscle
Nutritional status
Pathophysiology
Frail Brain
Associated with increased risk of developing delirium and reduced survival
Associated Increased cognitive impairment Faster rate of cognitive decline
Independent association with dementia
Frail immune system
Reduced stem cells Blunting of antibody response Reduced phagocytosis Impaired antibody response to vaccines
Frail Immune system
Inflammation has a major role in the pathophysiology of frailty
Abnormal low-grade inflammatory response Hyper-responsive to stimuli Persists for a long period
Inflammation leads to anorexia and catabolism
Sarcopaenia
Frail skeletal muscle Progressive loss of muscle mass,
strength and power Reduction in functional ability
Frailty Models
Phenotype model
Cumulative deficit model
Phenotype model
Phenotype model
Detection of frailty in routine care Difficult to translate to clinical practice Those with cognitive impairment not
included Increased adverse outcome
Cumulative deficit model-Frailty Index CSHA 92 baseline variables (health deficits) Presence or absence of each variable as
a proportion of the total Defined as cumulative effect of
individual deficits Clinically attractive- frailty is gradable Strongly related to the risk of death and
institutionalisation
Prevalence
Systematic review Frail 9.9% Pre-frail 42% F>M Steadily increased with age
65-69 4% >85 26%
Outcomes
Most frail worst outcomes Frail more frail Higher risk of:
Worsening disability Falls Admission to hospital Death Admission to long term care
Association between frailty, disability and comorbidity
Assessments to identify frailty CGA CGA when linked to interventions has
superior outcomes Gold standard to assess frailty
Edmonton Frailty scale CSHA scale
Interventions
Inpatient CGA More likely to return home Less likely to have cognitive or functional
decline Lower in-hospital mortality
Community CGA Continuing to live at home
Interventions
Exercise
Effect sizes are small/moderate Intensity uncertain
Nutritional interventions Scarce evidence
Interventions
Drugs
ACEI Testosterone Vitamin D
Conclusion
Frailty is a state of vulnerability to poor resolution of homeostasis
Cumulative decline in many physiological systems during a life time
Minor stressor events trigger a disproportionate changes in health status
Landmark studies have been used to develop valid models of frailty
Association of frailty and adverse health outcomes
Conclusion
Care is organised around single organ disease
Frailty is a practical unifying notion Strongly associated with adverse
outcome Moving away from age to using frailty Best evidence is for comprehensive
geriatric assessment
