| Popis: | 93 Emergency response is a time critical work that needs team work from different organizations with various specialties. It also needs to integrate existing information system to collect and assemble necessary knowledge and resources for critical emerging tasks and use it to plan for collaborative problem solving In this study, we propose the methodology to automate the traditional emergency patient transfer process by connecting different organization’s information systems through Web services with BPEL4WS. Via Web services, the medical resources information can be requested according to patient conditions, and resource reservation decision can be made online. Via BPEL4WS, heterogeneous information systems in different organizations can be connected and executed automatically in any predefined process without limit human intervention. The willingness of hospitals to share various levels of resource availability information to Emergency Operation Center (EOC) to coordinate regional medical resource distribution is critical to make Web service platform work. Therefore, this study examines the correlation of individual hospitals’ performance in terms of resource utilization with hospital’s information sharing with EOC. We investigate the effects from sharing information to EOC which adopts three policies of releasing hospital status information through simulation under different conditions in emergency occurrence and occupied hospital resources. Our findings from the simulations imply that the best policy for EOC to adopt in order to make Web services workable in handling medical emergency is to accord different conditions to adopt different suitable policies. For hospitals, if they want to get the maximum resources utilization, it had better to refer to different condition to adopt different information sharing strategies. |
