Book Description
Objective: To compare medical care costs and utilization in a consumer directed health plan (CDHP) to other health insurance plans. Study Design: We examine claims and employee demographic data from one large employer that adopted a CDHP in 2001. A quasi-experimental pre/post design is used to assign employees to three cohorts: 1) enrolled in an HMO from 2000 to 2002, 2) enrolled in a PPO from 2000 to 2002, or 3) enrolled in a CDHP in 2001 and 2002, after previously enrolling in either an HMO or PPO in 2000. Using this approach we estimate a difference-in-difference regression model for expenditure and utilization measures to identify the impact of CDHP. Principal Findings: By 2002, the CDHP cohort experienced lower total expenditures than the PPO cohort but higher expenditures than the HMO cohort. Physician visits and pharmaceutical use and costs were lower in the CDHP cohort compared to the other groups. Hospital costs and admission rates, for CDHP enrollees, as well as total physician expenditures, were significantly higher than for enrollees in the HMO and PPO plans. Conclusions: An early evaluation of CDHP expenditure and utilization reveals that the new health plan is a viable alternative to existing health plan designs. Enrollees in the CDHP have lower total expenditures than PPO enrollees, but higher utilization of resource-intensive hospital admissions after an initially favorable selection.
