Multimorbidity and functional status in older people: a cluster analysis

Area of Science:

• Gerontology
• Clinical Medicine
• Public Health

Background:

• Multimorbidity and frailty are prevalent and complex conditions in the aging population.
• Understanding disease patterns within these groups is crucial for effective healthcare.
• Previous research has not fully elucidated specific chronic disease clusters in relation to frailty status.

Purpose of the Study:

• To identify distinct clusters of chronic diseases in both robust and frail older individuals.
• To compare sociodemographic and health characteristics across these identified disease clusters.
• To inform clinical management strategies for older adults with multiple chronic conditions.

Main Methods:

• Cross-sectional study utilizing electronic health records and baseline assessments.
• The Timed Up and Go test was employed as a measure of physical performance and frailty.
• Multiple correspondence and cluster analyses were performed to identify disease groupings.

Main Results:

• 813 individuals (mean age 77.4 years) were analyzed, with 244 identified as frail.
• Three clusters were found in robust individuals and four in frail individuals.
• A novel cluster (FC4) among frail individuals showed high rates of cognitive and eye problems, indicating a particularly poor health status.

Conclusions:

• Chronic disease clusters, while showing some similarities, present unique profiles in robust versus frail older adults.
• The identification of specific clusters, especially the novel frail cluster (FC4), can aid in targeted clinical interventions.
• This research provides valuable data for the clinical management of older patients experiencing multimorbidity and frailty.
