Description of Databases
The Dorenfest Complete Integrated HEALTHCARE DELIVERY SYSTEM PLUS (IHDS+) DATABASE™ is a market intelligence tool that has profiled Hospital and Integrated Delivery System IT efforts from 1986 up to two years before the current year. From 1986 to 1995, Sheldon I. Dorenfest & Associates, Ltd. tracked demographic and information systems data for all non-federal acute care facilities with 100 beds or more in THE DORENFEST 3000+ DATABASE™.
In 1998, THE FIRST DORENFEST COMPLETE IHDS+ DATABASE™, which included all integrated healthcare delivery systems (IHDSs) that own at least one short term, acute care, non-federal hospital with at least 100 beds, was published. This product contains 1,467 IHDSs and data on over 32,000 facilities. The database provides a comprehensive picture of healthcare delivery in the United States. This was followed by updated versions in 1999, 2000, 2001, 2002, and 2003 (respectively, the SECOND, THIRD, FOURTH, FIFTH, and SIXTH DORENFEST COMPLETE IHDS+ DATABASE™).
