This document discusses the history and growth of outsourcing in healthcare IT. It describes how outsourcing allowed consulting firms like Superior and ACS to significantly increase their revenue by taking over hospital IT departments. Outsourcing became popular in the 1990s and spurred the growth of large consulting firms through acquisitions. Today, some of the largest HIS vendors and consulting firms generate billions in annual revenue, partly through IT outsourcing and system implementations. The document cautions hospitals to carefully consider a consulting firm's qualifications and potential conflicts of interest when engaging them for projects.
