title: Diffusion of telemedicine: a knowledge barrier perspective.
abstract: Telemedicine, broadly defined as the use of information technology (IT) to deliver medical services over distances, is one proposed solution to problems of accessibility, quality, and costs of medical care. Although telemedicine applications have proliferated in recent years, their diffusion has remained low in terms of the volume of consultations. In this study, we extend Attewell's theory of knowledge barriers to explain why diffusion of telemedicine remains low. A longitudinal, embedded multiple case study of telemedicine programs in three medical centers in Boston, Massachusetts, reveals that, in addition to technical knowledge barriers, as suggested by Attewell, there are economic, organizational, and behavioral knowledge barriers that inhibit the diffusion of telemedicine. The lowering of these barriers entails intensive learning efforts by champions of applications within adopter organizations. They need to develop technically feasible, medically valid, reimbursable, and institutionally supported applications in order to justify the value of telemedicine and engender consistent and frequent use by physicians.
