Abstract
Process management technology has recently been employed not only in businesses but also in healthcare information systems. In particular, urgent requests and critical messages in these systems (referred to as alerts) have to delivered and handled timely. Presently, most systems cannot address urgency, and alerts are often handled in an ad-hoc manner. In this paper, we propose a sophisticated alert management system (AMS) for effective healthcare chain workflow management under urgent constraints. We develop a model for specifying alerts, in which alerts are associated with healthcare tasks and a set of parameters are captured for their routing and urgency requirements. Further, alerts also serve as a mechanism for both process and data integration. The AMS matches the specialties of healthcare personnel and functionalities of Web Services providers to receive an alert, based on the alert specification. We then propose a routing mechanism that is initiated when the alert message is not acknowledged or serviced within the deadline, so that the alert can be forwarded to other suitable personnel if necessary. Monitoring is especially essential to ensure timeliness and availability of services, otherwise suitable exceptions should be raised and handled. We outline our implementation framework with Web Services and mobile devices. We demonstrate the applicability of our approach with a pilot prototype medical house-call system (MHCS).
1. Introduction
Recent advances in Internet technologies have created a global platform for organizations and individuals to communicate among one another, carry out various commercial activities, and provide value-added services. E-services refer to these services provided over the Internet. In the current highly competitive and dynamic digital economy, E-services need to response actively and timely to customers’ needs. For example in a B2C scenario, when a product recommendation portal finds a suitable product for a customer, the customer should be alerted promptly with the search results because second-hand items and clearance stock might be sold out quickly. Similarly, business-to-business (B2B) interactions may also have such requirements. Timely communication of accurate information is a key success factor for the provision of quality E-services. In particular, for E-services with stringent urgency requirements, such as healthcare and security applications, E-service providers must response actively and very timely to requestors’ needs as this may be crucial to success or failure.
There are several issues to be considered in this problem. The alert model should include various alert types and parameters that qualify the E-service provider to receive an alert. Apart from service suitability, application specific considerations like costs, waiting time, service time, etc., may also be important.
