This report describes the evolution of the electronic clinical decision support system (CDSS) and feedback methods at our center and the challenges and lessons learned. The electronic blood product order with integrated CDSS ensures collection of data regarding the patient's clinical condition and the justification for the blood product order. An alert is generated in real time if the order is placed outside agreed guidelines. We have provided feedback in several ways. We began with monthly review meetings with the junior hematology clinicians responsible for ordering blood. This was successful in reducing unjustified transfusions in this setting. We expanded the feedback to the rest of our hospitals in two ways. First, a dashboard was developed allowing visualization of ordering data by clinicians. Second, these data were summarized on a quarterly basis into a report circulated to the senior clinical staff by e-mail. Finally, a daily report collates all orders placed for blood products that have triggered a CDSS alert from the previous day. A multidisciplinary team reviews these daily. If an order appears unjustified the specialist transfusion clinician contacts the prescribing clinician to ask for further information and, if necessary, provides education. The CDSS and feedback, allied with other patient blood management measures, have reduced total blood product costs for our hospitals by 26% over 6 years. The description of how we have developed and implemented CDSS and feedback to influence transfusion practice may be of particular value to others developing their own systems.
