Managing Technological Change in a Military Treatment Facility: A Case Study ofMedical Diagnostic Imaging Support (MDIS) System

摘要

Picture archiving and communication system (PACS) represents an enormouslyexpensive technological innovation in digital imaging which has the potential to alter the way in which radiology is practiced. The purpose of this thesis is to provide a better understanding of the requirements for PACS technology and the implementation of information systems in medical facilities. The objective of PACS technology is to improve access to radiographic images and reports throughout medical facilities while decreasing the cost of image production and storage. Medical Diagnostic Imaging Support (MDIS) system is the military tri-service project to install PACS in selected U.S. military medical treatment facilities (MTF) in an attempt to create a totally filmless environment. This thesis includes a case study of the implementation of the MDIS system at Madigan Army Medical Center and the change management issues that surround the introduction of an information system in a health care organization. The issues brought forth in this study are derived from two change models in the implementation of information systems.
