Do consumer-directed health plans drive change in enrollees' health care behavior?

Abstract

Using panel data from two surveys of employees at one large employer from 2004 and 2005, this paper examines consumer-directed health plans' (CDHPs') influence on the use of health-related information and health services. We compare enrollees in a high-deductible CDHP, a lower-deductible CDHP, and a preferred provider organization (PPO). Enrollees in the lower-deductible CDHP were more likely than enrollees in the other plans to start using information. Enrollees in the high-deductible CDHP were more likely than those in the PPO to start forgoing medical care to save money.
