The introduction of an information technology (IT) system that mandates order entry by physicians had significant and often unexpected effects on medical education at the University of Virginia Medical Center. The system was deactivated briefly after the introduction of laboratory ordering, and frustration with the pharmacy ordering pathways provoked a major confrontation between the residents and medical center management. With time and experience, however, the housestaff have adjusted to the system and developed facility in using it. Much of the dissatisfaction was derived from the perception that "doctors spend too much time on the computer." In fact, less than 10% of the physicians spent more than an hour each day. However, a small group of residents on call for the busier services were sometimes at the computer for more than four hours each day. Changes in responsibilities, patterns, and priorities of work introduced by the system also contributed significantly to the general dissatisfaction. These issues had not been thoroughly considered in the planning stage, but it was only after accommodation was made to these changes that integration of the technology into routine practice could proceed. The author emphasizes the importance of extensive involvement and leadership of attending physicians in the planning and implementation of such a system. He presents a set of recommendations to those considering similar IT initiatives and wishing to reduce the disruptions that may accompany their introduction.
