Abstract

In previous studies, the technology acceptance model(TAM) [1] has been widely used by informationtechnology researchers to gain a better understanding ofinformation technology (IT) adoption and its use inorganizations. While TAM has been applied and tested inacademic and corporate settings, involving students,business managers, clerical and administrative types assubjects, few studies have evaluated TAM in the healthcare environment.This study examines the applicability of the extendedTechnology Acceptance Model (TAM2) [2] in the contextof physicians' intention to adopt Internet-based healthapplications.Data were collected in a survey of pediatricians to seehow well the extended model, fits in the medical sector.Our results partially confirm the model, howeversignificant theoretical aspects were not supported. One ofthe core perception variables, perceived ease of use, didnot predict intention to use in this study. As theorized, theprimary predictor variable perceived usefulness was astrong determinant of intention to use. This paperdiscusses the implications, limitations, and possibleexplanations for the inconsistencies within the modelwhen applied to such professional users as physicians.
