OVERVIEW OF SOME METHODOLOGICAL PROBLEMS IN ASSESSMENT OF PACS

The purpose of technology assessment of picture archiving and communications systems (PACS) is to establish the need for the technology, provide a measure of functionality and to establish the costs and benefits associated with the introduction of the system. Given concerns about the clinical acceptability of PACS, it is unlikely that radiologists will change from existing film based systems until a clear demonstration of costs and benefits has been performed. The major need at present is to quantify the benefits which may flow from the introduction of PACS system in a standard manner which can be accepted by all parties involved.
