Screening for frailty in older adults using a self-reported instrument

Area of Science:

• Gerontology
• Public Health
• Clinical Assessment

Background:

• Frailty syndrome is a significant health concern in older adults.
• Accurate screening tools are crucial for timely intervention.
• Existing frailty assessments can be time-consuming or complex.

Purpose of the Study:

• To validate a self-reported screening instrument for frailty syndrome in individuals aged 75 years and older.
• To assess the reliability and validity of a novel, simplified frailty assessment tool.

Main Methods:

• Cross-sectional study utilizing data from 433 older adults (≥75 years).
• A self-reported questionnaire assessing frailty phenotype components (weight loss, fatigue, activity, strength, walking speed).
• Psychometric analysis including Cronbach's alpha, sensitivity, and specificity.

Main Results:

• Decreased walking speed and strength showed good internal consistency (α=0.77, 0.72).
• The tool demonstrated high sensitivity (89.7%) for identifying the 'process of frailty' (pre-frail and frail).
• Sensitivity for frail individuals was 63.2%, with specificity of 71.6%.

Conclusions:

• Self-reported frailty assessment is a valid screening tool for older adults.
• The instrument is simple, rapid, cost-effective, and suitable for various healthcare professionals.
• This tool facilitates the identification of frailty syndrome, enabling prompt management.
