Research and Development Plan: With extensive experience in designing and evaluating health care informatics innovations, we have assembled a multi-disciplinary team with expertise from primary care internal medicine, clinical informatics, health services research, qualitative research, clinical pharmacy, nursing and industrial engineering. This team will carry out a formative evaluation and develop a prototype of a secure electronic message to facilitate medication reconciliation following hospital discharge. The proposed CIMIT project will leverage the resources and expertise of the e-Health QUERI (a national VA program for innovation and evaluation of the VA's e-Health programs) at VA Boston and other participating VA facilities nationwide. The figure below shows a very rough conceptualization of the SEC that will guide the qualitative research and participatory design of the prototype. This project will lay the foundation for a future rigorous evaluation of this approach to medication reconciliation and improving patient safety.
