The success of information systems in healthcare contexts is becoming increasingly important as the healthcare profession continues to adopt information systems for its internal operations. Using the DeLone and McLean model of information systems success that has found traction in a variety of research contexts, we develop a model for examining the success of clinician information systems. Our research model, while grounded in prior literature on information systems success, also benefits from insights gained from preliminary interviews and surveys of healthcare professionals and clinicians. The pilot round of data collection is planned for next month and actual data collection for summer; we will present preliminary findings at the conference.
