A Theoretical Model of Observed Health Benefits of PACS Implementation

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.
