Healthcare IS industry top 100. HBOC tops out 100

The Healthcare Informatics Top 100 ranks the leading information system software providers to the healthcare industry by revenues. Due to the limited focus of the healthcare IS industry, many Top 100 companies serve other markets in addition to IS or healthcare. Thus, to most accurately compare companies, we asked cross-industry companies and companies with non-IS specific offerings to separate out those revenues specific to healthcare information systems. For some companies this proved an impossible task. In such cases, we relied on estimated revenues provided by professional sources throughout the industry. (Such companies are marked by an asterisk on the Top 100 list). According to industry analyst Sheldon I. Dorenfest of Sheldon I. Dorenfest & Associates, Chicago, the healthcare information systems marketplace can be divided into three parts: sales of computer and networking equipment account for 62 percent of revenue, software and software associated management services account for 33 percent, and consultation and other management services account for 5 percent. The Healthcare Informatics Top 100 features companies offering software and software associated management services as primary source of revenue (this includes resales of hardware and networking equipment). Companies not eligible for the Top 100 include investment companies, and companies for which consulting, non-software management services, or hardware or medical equipment is the primary source of revenue.
