The FRAIL Scale: A Simple Tool for Screening Frailty
The FRAIL scale is a widely used and straightforward screening tool designed to quickly assess an individual's level of frailty. Developed by the International Association of Nutrition and Aging (IANA), its name is an acronym for its five components: Fatigue, Resistance, Ambulation, Illnesses, and Loss of Weight. While all five components contribute to the final frailty score, the 'Illnesses' section specifically lists a set of chronic diseases and is a key factor in the evaluation. A person is considered to be in the 'frail' category if they score three to five points, and 'pre-frail' with a score of one or two points. A higher score indicates a greater risk of disability, hospitalization, and mortality.
A Deeper Look at the 'Illness' Component
The Illness section of the FRAIL scale is specifically designed to account for the impact of multimorbidity, which is the co-occurrence of multiple chronic diseases in the same individual. This is one of the most critical aspects of the assessment, as the burden of disease significantly influences an individual's physiological reserve and overall health trajectory. For this component, one point is assigned if a patient reports having five or more of the designated chronic diseases. The scale identifies a specific list of 11 conditions for this assessment.
The Specific Diseases on the FRAIL Scale List
The designated diseases that contribute to the 'Illness' score on the FRAIL scale include:
- Hypertension (High Blood Pressure): A common chronic condition that increases the risk of heart attack, stroke, and kidney disease.
- Diabetes Mellitus: This metabolic disorder can lead to systemic complications, including heart disease, kidney damage, and nerve damage, which significantly impact physical function.
- Cancer (excluding minor skin cancer): A broad category of diseases that can drastically deplete a person's physiological reserves, especially during and after treatment.
- Chronic Lung Disease: This includes conditions like chronic obstructive pulmonary disease (COPD), emphysema, chronic bronchitis, and asthma, which restrict respiratory capacity and reduce physical activity.
- Heart Attack (Myocardial Infarction): A cardiovascular event that often leads to permanent heart damage and reduced cardiac function.
- Congestive Heart Failure (CHF): A progressive condition where the heart cannot pump enough blood to meet the body's needs, leading to fatigue and reduced physical capacity.
- Angina (Chest Pain): A symptom of coronary artery disease that limits physical exertion.
- Arthritis: Joint inflammation and stiffness, which directly impacts resistance and ambulation—two other components of the FRAIL scale.
- Stroke: A cerebrovascular event that can cause significant and permanent functional impairment, affecting mobility and overall independence.
- Kidney Disease: Conditions like chronic kidney disease (CKD) are associated with systemic inflammation, which is a known contributor to frailty.
- Asthma: While sometimes included in the broader 'chronic lung disease' category, it is specifically listed in some versions of the FRAIL illness checklist as a condition that can impact a person's resistance and ambulation.
Comparison with Other Frailty Assessment Tools
It is important to recognize that the FRAIL scale is just one method of assessing frailty. The term 'frail scale' can be misleading as other, more comprehensive tools incorporate a wider range of health deficits. Understanding these differences helps in gaining a complete picture of a senior's health.
| Assessment Tool | Assessment Focus | Inclusion of Diseases | Examples | Score Range |
|---|---|---|---|---|
| FRAIL Scale | 5 components: Fatigue, Resistance, Ambulation, Illness, and Loss of Weight. | Focuses on a specific list of 11 chronic diseases. | Used for quick, simple screening in clinical settings. | 0 (Robust) to 5 (Frail) |
| Clinical Frailty Scale (CFS) | Based on clinical judgment of an individual's overall fitness and function. | Integrates diseases into a broader assessment of functional status. | Uses a narrative scale from 'very fit' (1) to 'terminally ill' (9), with illustrative pictures. | 1 (Very Fit) to 9 (Terminally Ill) |
| Frailty Index (FI) | Accumulation of deficits model, counting health problems. | Incorporates a wide range of deficits, including chronic diseases, cognitive status, and social factors. | Uses a long checklist (e.g., 70+ items) to calculate a ratio of deficits. | 0 to 1 |
The Broader Impact of Chronic Disease on Frailty
While the FRAIL scale identifies a list of 11 diseases, the underlying connection between chronic illness and frailty is complex and goes beyond a simple checklist. Chronic diseases, especially when multiple are present (multimorbidity), place a significant burden on the body's physiological systems. This leads to a reduction in physiological reserves, which is a hallmark of frailty. Systemic inflammation, often associated with chronic diseases like cardiovascular disease and chronic kidney disease, further contributes to the decline in muscle mass (sarcopenia), exhaustion, and reduced physical activity seen in frailty. This creates a vicious cycle where chronic disease worsens frailty, and frailty increases the risk of adverse outcomes related to those diseases.
How to Manage and Potentially Reverse Frailty
Early detection and targeted intervention are crucial for managing and even reversing frailty, particularly by addressing the underlying chronic diseases. A tailored, multi-pronged approach is often recommended.
- Physical Activity: Regular, moderate-intensity exercise, especially resistance training, has been shown to be highly effective in preventing and reversing frailty. A personalized exercise plan can improve muscle strength, balance, and aerobic capacity, directly addressing some of the core deficits of frailty.
- Nutritional Support: Proper nutrition is essential, particularly adequate protein intake, to combat muscle wasting and support overall health. Consulting with a dietitian can help create a diet plan to meet the specific nutritional needs of older adults.
- Chronic Disease Management: Optimally managing chronic diseases like diabetes, heart failure, and hypertension is critical. Adhering to treatment plans can help stabilize health and prevent further physiological decline.
- Social and Psychological Engagement: The social and psychological aspects of frailty cannot be ignored. Providing opportunities for social engagement and addressing mental health concerns like depression can improve motivation and overall well-being.
The reversibility of frailty is possible through such comprehensive, personalized interventions, especially when identified early. This highlights why tools like the FRAIL scale are so important for routine screening.

Conclusion
While the search query asks what are the diseases on the frail scale, the term 'frail scale' can refer to a few different assessment tools. The specific list of 11 diseases is used in the 'Illness' component of the FRAIL questionnaire, a simple screening tool. However, other assessments, like the Clinical Frailty Scale and the Frailty Index, integrate chronic diseases into a much broader evaluation of an individual's overall health and functional reserves. Regardless of the tool used, the presence of chronic diseases is a critical factor in frailty. Proactive management of these conditions, combined with tailored interventions focusing on exercise, nutrition, and social engagement, is key to delaying, managing, and even reversing frailty, thereby improving health outcomes in older adults.
