The spending in healthcare is constantly increasing according to available data, and the resource consumption does not actually reflect expected improvement in the healthcare services. As a result there is urgent need for healthcare to reengineer their business process in order to achieve improvements in critical area such as cost and quality. To address this issue, this study proposed a method based on design science approach by integrating knowledge map, enterprise ontology and lean in order to find the non-value added transactions and subsequently reengineer them to enhance healthcare efficiency. Enterprise ontology provides a details and better understanding of dynamic nature of an organization as such was chosen for as basis for this study. The method was demonstrated in radiology department making it possible to find and addresses non-value added transactions and subsequently reengineer the department. Evaluation was carried out by means of descriptive method using Moody and Shank framework and interview with healthcare practitioners. The finding shows that the method has enhanced healthcare efficiency by eliminating non-value added transactions.

<p>As global spending on healthcare increases and service improvement is not adequately reflecting on resource consumption, many healthcare organizations therefore resolve to improving their services by implementing Business process reengineering (BPR). BPR is a business strategy adopted by so many healthcare organizations in order to efficiently and successfully manage their business using currently available technology. BPR has been a hot topic in Information Systems discipline and extensive research has been carried out in different settings with numerous methodologies and approaches. As a result of ever changing nature of BPR this paper intend to provide additional knowledge exploring the current level of development of BPR in healthcare. To achieve this, a total of 27 articles from Science Direct database, 15 from IEEE explore, 16 from Taylor &amp; Francis, 25 from SpringerLink and 8 from SAGE Hub database covering the period from 2005 to early 2014 were analyzed based on their setting and methodology. And finally the article concludes with suggestions for future research related to BPR in healthcare.</p>
