Frailty Flashcards
What is phenotypic frailty vs. index frailty?
Phenotypic (physical) = due to dysregulation of physiologic processes causing vulnerability to adverse health outcomes
Index (cumulative deficit) = accumulation from a number of disease, impairments and other health conditions
What is the Fried definition of frailty?
A biologic syndrome due to
Cumulative declines across multiple physiologic systems
Leading to decreased reserve and resistance to stressors
Causing vulnerability to adverse outcomes
What are 5 characteristics of phenotypic frailty (Fried)?
- Shrinking - weight loss >10 lb 1 year or >5% body weight
- Weakness - grip strength lowest 20%
- Poor endurance/exhaustion - self reported questionnaire
- Slowness - gait speed lowest 20%
- Low activity - self report questionnaire
What are three instruments for measuring frailty?
- Physical frailty phenotype (Fried)
- Deficit Accumulation Index (Frailty Index)
- Clinical Frailty Scale (Rockwood)
Why are frailty instruments limited?
- Need to study validity
- Need to study feasibility
- No validated for clinical decision making or interventional target
SPRINTT results - effect of moderate intensity exercise and personalized nutrition counselling on mobility disability
Baseline SPPB score 3-7 (more frail)
Less incidence of mobility disability
What are 6 interventions to reduce frailty or prevent progression?
- Exercise (Strength, resistance)
- Nutrition (protein, calorie)
- Medication review
- Social engagement/supports
- Target sensory deficits
- CGA
List 9 nutritional deficits that may be associated with frailty?
Vit B12
Vit C
Vit D
Vit E
Folate
Carotenoids
Insufficient protein intake
Poor quality diet
Low antioxidant
What was the main finding of the DELIVER trail re: worsening CHF events or CVD death
Dapagliflozin decrease risk of primary end point
What did the DELIVER study find about the impact of dapagliflozin for more frail patients?
Associated with greater symptomatic improvement for more frail patient
In the DELIVER trial, compared with less frail pts what did the study find re: ADRs and treatment discontinuation for more frail pts?
ADRs and treatment discontinuation were not more common with dapagliflozin than placebo, irrespective of frailty
What is the CFS for bed bound, dependent all ADLs?
CFS 7 = Severe frailty
? 8 - may die within 6 months
CFS?
84 yo, home with wife, MNCD, uses cane, wife does IADLs, independent BADLs
CFS 5 = mild frailty
CFS?
87 yo M, PD, assistance with bathing and dressing, eats independent
CFS 6 = moderate frailty
Fried frailty scale pro and con
Pro: independently predicts falls, hospitalizations, disability and death
Con: doesn’t include psychosocial components of frailty
