InterStudy Publications, a division of Decision Resources, announces the release of its Spring 2004 Competitive Edge HMO Directory. This resource is used by health care analysts around the country to track competing HMOs and compare HMO growth in various states or regions.

"The Competitive Edge HMO Directory is a critical resource for anyone making strategic managed care decisions," said Nicole Garberg, HMO project manager for InterStudy. "It supplies information on changes in providers and enrollment for the past three years and presents HMO profiles in a consistent manner for easy comparison."

InterStudy publishes the Competitive Edge series semiannually. The HMO Directory is the first of this three-part series on HMOs. Part II, The HMO Industry Report, analyzes plan growth and characteristics associated with growth in HMOs. Part III, The Regional Market Analysis, examines market structure and dynamics of metropolitan markets served by HMOs. These studies are built on the industry's most reliable research methods, with survey response rates of 90% or better.
