First results with the software package CAPACITY for cost modeling of PACS

Abstract
An essential element in the decision of introducing a PACS will be its financial implication. We all hope PACS will come affordable at a certain point in time because of the decreasing hardware prices. However there is a wide variety of opinions about the moment the savings of PACS will exceed its costs. A software package for cost modelling of PACS, named CAPACITY, was developed by BAZIS in order to to get a better understanding of the cost characteristics of PACS. CAPACITY makes a cost comparison over the years thus indicating the moment of break even. User given input values are checked by a critique module and a file of cases can be maintained. One of the activities within the Dutch PACS project, a cooperative effort of BAZIS, the Utrecht University Hospital (UUH) and Philips Medical Systems is to indicate the costs of a PACS in the Utrecht University Hospital. A number of scenarios for a PACS in the Utrecht University Hospital have been defined and evaluated with the software package CAPACITY. The results will be discussed and it will be shown that the workstations play a major role.
