Abstract

Background

Programs to improve quality of care and lower costs for the highest utilizers of health services are proliferating, yet such programs have difficulty demonstrating cost savings.

Objective

In this study, we explore the degree to which changes in Patient Activation Measure (PAM) levels predict health care costs among high-risk patients.

Participants

De-identified claims, demographic data, and serial PAM scores were analyzed on 2155 patients from multiple medical groups engaged in an existing Center for Medicare and Medicaid Innovation-funded intervention over 3 years designed to activate and improve care coordination for high-risk patients.

Design

In this prospective cohort study, four levels of PAM (from low to high) were used as the main predictor variable. We fit mixed linear models for log10 of allowed charges in follow-up periods in relation to change in PAM, controlling for baseline PAM, baseline costs, age, sex, income, and baseline risk score.

Main Measures

Total allowed charges were derived from claims data for the cohort. PAM scores were from a separate database managed by the local practices.

Key Results

A single PAM level increase was associated with 8.3% lower follow-up costs (95% confidence interval 2.5–13.2%).

Conclusions

These findings contribute to a growing evidence base that the change in PAM score could serve as an early signal indicating the impact of interventions designed for high-cost, high-needs patients.
