Abstract

Picture Archiving and Communication Systems (PACS) is an important e-health application, playing a significant operational role within hospitals in electronically transmitting image-based data. Various authors have attributed a range of benefits to PACS, including diagnostic accuracy (Scott et al., 1995; Slasky et al., 1990), interpretation time savings (Kato et al., 1995), workflow (Gale, Gale, Schwartz, Muse & Walker, 2000) and user satisfaction (Philling, 1999). While there is general consensus that PACS brings some or all of these benefits, there is little agreement as to the mechanism through which these benefits are generated. The work of Delone and McLean (2003) provides a generalized model that attributes information systems success to benefits accruing from relationships between characteristics of the information system (e.g., information quality, system quality, service quality) and user intention to use and user satisfaction (see Figure 1). This chapter provides empirical evidence that the Delone and McLean (2003) model with modifications explains the source of PACS benefits. Not only do we suggest a new model, but we also recommend that each specific information system context may require specific modification of Delone and McLean’s (2003) model to explain the source of success.
