Frailty And Multimorbidity: 8 Practical Strategies

As people age, the likelihood of developing

frailty

and

multimorbidity

increases significantly. Around one in ten individuals over 65 is considered frail, while up to half may experience multiple chronic conditions, posing challenges to daily life and healthcare systems.

What is frailty?

In everyday terms, frailty describes a state of weakness, delicacy, and vulnerability, often stemming from health issues that heighten susceptibility to illness, falls, or hospitalization. Medically,

frailty

is a syndrome characterized by decreased physiological reserves and heightened vulnerability to adverse outcomes like disability, hospitalization, and mortality.

Frailty arises from multisystem declines linked to aging, exacerbated by factors such as oxidative stress, chronic inflammation, physical inactivity, and undernutrition. It differs from normal aging or specific diseases, representing a distinct clinical entity where small stressors can trigger major health declines.

What is multimorbidity?

**Multimorbidity** refers to the coexistence of two or more chronic conditions in an individual, increasingly common in older populations and presenting substantial care challenges. Common contributors include cardiovascular diseases, diabetes, arthritis, mental health disorders, sensory impairments, and frailty itself.

The prevalence rises with age and socioeconomic deprivation, with physical-mental comorbidities more frequent in deprived groups. Unlike single diseases, multimorbidity leads to fragmented care, polypharmacy, and reduced quality of life.

How common are frailty and multimorbidity?

Frailty affects about 10% of those over 65, rising sharply with age. Multimorbidity impacts up to 50% of older adults, with 72% of frail individuals also multimorbid and 16% of multimorbid people frail.

• Prevalence of multimorbidity in frail older adults: 72% (95% CI 63%–81%).
• Prevalence of frailty in multimorbid individuals: 16% (95% CI 12%–21%).
• In COVID-19 patients, frail multimorbid individuals had 75% in-hospital mortality vs. less than 2% in those without both.

Why are frailty and multimorbidity linked?

Frailty and multimorbidity frequently coexist, sharing risk factors like obesity, smoking, sedentary lifestyle, and inflammation. Frailty lowers the threshold for disease onset, while chronic conditions like cardiovascular disease, diabetes, and renal issues accelerate frailty via mechanisms such as sarcopenia and electrolyte imbalance.

Not all multimorbid individuals are frail, offering a window for preventive interventions. Their interplay forms a ‘geriatric triangle’ with polypharmacy, demanding holistic management.

What are the risks of frailty and multimorbidity?

These conditions amplify adverse outcomes:

• Increased hospitalization and mortality risk (e.g., CFS score increments raise death risk by HR=1.3).
• Reduced quality of life and functional decline.
• Falls, disability, and dementia (vascular/Alzheimer’s).
• Care fragmentation, multiple appointments, and high costs.
• Polypharmacy (59% in frail adults), increasing adverse drug reactions.

Condition Combination	In-Hospital Mortality (COVID-19 Example)
No multimorbidity or frailty	<2%
Multimorbidity only	28%
Frailty + Multimorbidity	75%

Assessing frailty

Frailty screening uses tools like the

Clinical Frailty Scale (CFS)

, a 9-point scale from 1 (very fit) to 9 (terminally ill), with ≥6 indicating moderate-severe frailty. Comprehensive Geriatric Assessment (CGA) evaluates medical, psychological, and functional abilities multidimensionally.

Other indicators: unintentional weight loss, exhaustion, weakness, slow gait, low activity. Early identification via CGA improves prognosis in multimorbid frail elders.

Assessing multimorbidity

No universal count exists; focus on impactful clusters (e.g., physical-mental). Tools consider socioeconomic factors, frailty, and care needs. NICE guidelines flag complex cases: ≥10 medications, frequent emergencies, or frailty/falls.

Prevention and management of frailty

Prevention targets modifiable risks:

• Exercise: Resistance/strength training, balance activities to combat sarcopenia.
• Nutrition: Protein-rich diet, address undernutrition.
• Lifestyle: Quit smoking, manage weight, stay active.
• Medical: CGA, treat inflammations early.

Management: Multidisciplinary CGA, deprescribing polypharmacy, frailty rehab programs.

Prevention and management of multimorbidity

Emphasize holistic care over disease silos:

• Coordinate care to reduce fragmentation.
• Prioritize patient goals, especially in limited life expectancy/frailty.
• Primary prevention reduces inequalities.
• Review medications, balance risks/benefits.

Polypharmacy in frailty and multimorbidity

**Polypharmacy** (multiple medications) affects 59% of frail elders, bidirectionally linked: drugs cause frailty (e.g., PIMs), frailty worsens disease needing more meds. Strategies: Deprescribe inappropriate meds, monitor adverse reactions.

The geriatric triangle

Frailty, multimorbidity, and polypharmacy interconnect bidirectionally, forming the ‘**geriatric triangle**’. Addressing one without others fails; holistic strategies targeting all are essential.

Comprehensive geriatric assessment (CGA)

CGA is pivotal: multidimensional evaluation optimizing outcomes in frail multimorbid patients. Improves function, reduces admissions.

Frequently Asked Questions (FAQs)

Q: How can I prevent frailty as I age?

A: Engage in regular exercise, eat a nutrient-rich diet, stay socially active, and get routine health check-ups to monitor reserves.

Q: Is multimorbidity inevitable with age?

A: No, while common, lifestyle changes and early interventions can delay or mitigate it, especially in non-frail individuals.

Q: What is the Clinical Frailty Scale?

A: A 9-point tool assessing fitness from 1 (very fit) to 9 (terminally ill); scores ≥6 signal need for intervention.

Q: How does polypharmacy affect frail seniors?

A: It increases adverse reactions and frailty risk; regular reviews and deprescribing are crucial.

Q: Can frailty be reversed?

A: Yes, with exercise, nutrition, and CGA, many improve, preventing progression to disability.
