Welcome to the 14th annual Healthcare Informatics 100. Here you will find the top 100 companies ranked by 2006 healthcare IT revenue. Collectively, these companies sold over $115 billion in IT products and services to health plans, provider organizations and other business entities, offering everything from highly specialized best-of-breed applications to comprehensive enterprise-wide solutions.
As you peruse our annual ranking, keep in mind that data is self-reported. As such, we rely on the honor system, asking companies to report only healthcare IT-generated revenues and to do it accurately. Though not perfect, we have faith our survey provides a valuable resource to the industry.
The always-changing composition of this annual list reflects the nature of a dynamic, mercurial industry fueled by strategic acquisitions, market consolidation, and the fierce entrepreneurial drive of newcomers. Some companies may have a significantly different ranking than previous years because of changes in how IT revenues were attributed or defined as a result of reorganization. And absent entirely are some large industry players due to limits on the granularity of information they are willing to share.

In the tables below are some slices of data you may find interesting, such as the largest movers in both percentage and dollar amount increase and decrease. After the ranking, check out pages 60 through 95 which contain profiles of companies making our Headliners (10 companies from the top 40), Up and Comers (eight companies selected from the bottom 60), and Others To Watch (six companies that submitted, but didn't make the cut) lists, as well as a story on mergers and acquisitions by HCI Editorial Board Member Ben Rooks. We rely on the vendors and service providers to make this list a solid resource. So for those companies that have a large presence in healthcare IT but decline to enter, we ask them to reconsider. And for those that entered but didn't make the cut, we ask them to try again next year. Perhaps a suggestion from you — our readers/their customers — might bring about their appearance on next year's list. — The Editors
