model [8], which extended the technology acceptance model by adding social influence and facilitating conditions as direct predictors of user acceptance. Social influence refers to perceived norms in the social environment concerning the use of a technology; and facilitating conditions refer to objective factors that facilitate the use of a technology, such as training, support and compatibility between the new and existing systems. Another related model for management issue is the information system (IS) success model by DeLone and McLean [9]. They included user satisfaction in addition to usage (including user acceptance) in their IS success model because user satisfaction is an alternative measure of system value in cases of obligatory use. They subdivided success measures of IS into six distinct categories: 1) system quality; 2) information quality; 3) usage; 4) user satisfaction; 5) individual impact; and 6) organizational impact. Within each category, several attributes could contribute to success. The information processing system itself is assessed with system quality attributes (e.g., usability, accessibility, ease of use). Information quality attributes (e.g., accuracy, completeness, legibility), concern the input and output of the system. Usage refers to system usage or information usage after user accepted the system. In their view, system quality and information quality individually and jointly affect usage and user satisfaction. Individual impact is a measure of the effect of the system or the information on users’ behavior, and attributes can be information recall or the frequency of data retrieval or data entry. Organizational impact refers to the effects of the system on organizational performance. The IS success model has also been widely applied in HIT to identify the factors influencing user satisfaction in the areas of computerized physician entry system (CPOE) [10], clinical information Management Issues in Healthcare Information Technology
