Successful implementation of an integrated physician order entry application: a systems perspective.

Direct physician order entry is required for effective implementation of an integrated electronic medical record. This effort involves multi-level changes in the whole system of care, from physicians attitudes to interdepartmental relations. This study reports the findings of a follow-up study that quantified dimensions associated with successful implementation identified in a previous study. Results identified several implementation strategies associated with success. These include an interdisciplinary implementation group, involvement of large numbers of regular staff, early and intensive training and support, and 24 hour available assistance as important to success. In addition, attitudes of physicians and their level of involvement were found to be associated with success.
