Abstract

Purpose of Review

Over half of the older adults in the USA have multimorbidity, defined broadly as the presence of two or more chronic diseases in an individual. Multimorbidity has significant overlap with disability and frailty. In this review, we broadly review the concepts of multimorbidity, disability, and frailty, as well as their interrelationships, and ability to predict future adverse health outcomes in older adults.

Recent Findings

Depending on the study, the prevalence of individuals with all three of multimorbidity, disability, and frailty ranges from 2 to 20%. Multimorbidity and patterns of multimorbidity are predictive of functional limitations, disability, health care usage, and mortality. The degree to which multimorbidity predicts these outcomes depends on many factors but partly upon the population examined and the presence of frailty and disability.

Summary

Multimorbidity is an emerging public health concern that is observed with and predictive of disability and frailty.

Also examined CHD comorbidity pairs and reported that the largest decrements in physical functioning occurred for the three pairs involving geriatric conditions (hip fracture, cognitive impairment, and frequent faller), underscoring the importance of including geriatric conditions in measures of multimorbidity among older adults.

Found that age modifies the association between number of chronic diseases and functional limitations; older participants (≥ 70 years old) relative to younger participants (60–69 years) had more functional limitations as the number of diseases increased. The explanation for this age modification suggested by the authors is consistent with the DPM
