Predictors of Frailty Change in Home and Community-Based Services Populations

With unprecedented demand for Medicaid long-term services and supports, states are seeking to allocate resources in the most efficient way. Understanding the prevalence of frailty and how it varies across home and community-based services (HCBS) populations can assist states with more precise identification of individuals most in need of services. Early identification of individuals more likely to experience frailty changes could allow for enhanced care planning to prevent or slow the progression of decline.

Longitudinal study.

Data from Connecticut's assessment tool (based on interRAI-HC) were analyzed at 2 time points for 16,309 individuals receiving HCBS. The sample included assessments completed between November 1, 2017 and July 15, 2020 across 4 groups: older adults 65+ years old meeting nursing facility level of care (NF LOC), older adults 65+ years old not meeting NF LOC, individuals with acquired brain injury, and individuals <65 years old with physical disability.

We measured frailty using the Frailty Index (FI) and examined change in FI between baseline and follow-up. A change in FI score of at least ±0.03 was classified as a clinically meaningful change. We compared predictors of clinically meaningful decline or improvement using multivariate logistic regression.

In our sample, 54% of individuals experienced a clinically meaningful change: 42% declined and 12% improved. Individuals receiving in-home care services had lower odds of improvement across all HCBS groups and multiple frailty categories with odds ratios ranging from 0.35 to 0.68. Frail older adults 65+ years old meeting nursing facility level of care receiving physical therapy were 21% less likely to experience decline and 1.4 times more likely to improve.

The nature of HCBS support provided can impact changes in frailty status. More reactive services such as in-home care may contribute to frailty decline while rehabilitative services such as physical therapy may protect against decline.
