Article
Purpose Public hospitals in China usually rely on revenues from medical services and medications to compensate for major costs given their nonprofit nature. The lack of government subsidies and unreasonable prices of medical services have led to high medical costs and unbalanced reimbursement system for public hospitals. There is a critical need of...

Medication errors are major safety concerns in all hospital settings. The insufficient knowledge about managerial and process improvement strategies required to reduce medication errors can be considered as one of the most important factors holding back hospitals from achieving the desired goals for patient safety. However, strategies for medicatio...

Supply chain is a complex system that involves many system elements from various functional areas. Performance of a supply chain heavily depends on the effectiveness of communication and coordination among these system elements and functional areas. However, a large and complex supply chain usually makes it difficult to coordinate and thus degrades...
Article
Systems engineering approach has been used in many applications to achieve major improvements in quality and safety in a wide range of manufacturing and service industries. Current research indicates that one of the major reasons causing risks for patient safety and creating wastes to the hospital is the poor design of medication delivery systems....
Article
Full-text available
In concurrent engineering projects, tasks are usually interdependent among each other that require much iteration before completion where the critical path method/program evaluation and review technique (CPM/PERT) may not be applicable to help estimate the project duration. In addition, carrying out a large-scaled project in a dynamic environment h...

Given the complexity of today’s healthcare delivery systems, achieving high patient safety and operating performance will require better coordination and management of various healthcare professionals as well as multiple streams of workflows across care settings. Therefore the right resources will be utilized in the right place at the right time, and the patient waiting and the quality of care will be significantly improved. A better workflow coordination and synchronization through workflow redesign will have significant impact on operations efficiency, quality of care and cost savings to healthcare systems in our nation.
