A variety of factors determine the successful implementation of clinical information systems such as EMR's. A major determinant of implementation success is clinical users' acceptance and willingness to use the system. Previous studies have looked at communicating with and addressing physician concerns during and post-implementation of an EMR. Our qualitative study looked at communicating with and addressing concerns of physician (housestaff and attending) users on prior to (eve of) EMR implementation as well as determining the preferred means of communication.
