Clinical decision support (CDS) is a process for enhancing health-related decisions and actions with pertinent, organized clinical knowledge and patient information that can significantly improve health outcomesand healthcare delivery. However, their impact on clinical outcomes has been inconsistent. Rigorous and continuous evaluation of CDS is necessary for improving CDS. An interface prototype designed based on User and Task analysis wasevaluated to measure its usability and effectiveness in evaluating CDSeffectiveness for improving quality outcomes based on the analysis. The results show that task of evaluating CDS effectiveness is relatively hard, and moreworkmay be needed to guide usersreach correct conclusions.
