Developing a virtual patient record using XML and web-based workflow technologies.

Virtual patient records (VPR) provide a means for integrated access to patient information that may be scattered around different healthcare settings. Within the boundaries of a health district providing all levels of care, this concept can be implemented in a corporate Intranet environment to support longitudinal patient care activities across the participating healthcare providers. In this context, a VPR implementation enables autonomous healthcare providers to operate in a cooperative working environment and apply continuity of care. Workflow systems bring this collaboration and cooperation into effect by automatically routing the medical information needed by authorized actors in a healthcare process. This paper presents a VPR framework that allows integrating geographically dispersed medical information within a health district and enhancing collaboration and coordination of authorized workgroups by means of a web-based workflow system. An implementation of the proposed framework is also presented.

Specifying workflow process requirements for an emergency medical service.

Recent trends in healthcare delivery have led to a gradual shift in the conceptualisation of healthcare information systems towards supporting healthcare processes in a more direct way. The move towards integrated and managed care, which requires designing healthcare processes around patient needs and incorporating efficiency considerations has led to an increased interest in process-oriented healthcare information systems based on workflow technology. This means to actively deliver the tasks to be performed to the right persons at the right time with the necessary information and the application functions needed. Moreover, workflow technology promotes a component-oriented development whereby the process logic is separated from application logic. This paper presents an approach to capturing process logic requirements for healthcare workflow systems with a view to design a system that is easily adjustable to process changes and to evolving organizational structures at a reasonable cost.

Emergency healthcare process automation using workflow technology and web services.

Emergency healthcare delivery involves a variety of interrelated activities performed from the time of a call to the ambulance service until the time of patient's exit from the emergency department of a hospital. As these activities can be viewed as parts of inter-organizational healthcare processes that involve at least two organizations (e.g. an ambulance service and a hospital), there is a need to provide the appropriate technological infrastructure for automating and managing these processes even in cases where the organizations involved use heterogeneous systems to support their internal services. Web-based workflow systems in conjunction with web services present a new way for service-oriented integration (SOI) of disparate systems and for developing distributed applications within and between organizations. Thus, process automation with the use of web services can provide an appropriate infrastructure for the integration of pre-hospital and in-hospital emergency healthcare. A prototype development of such a system is presented in this paper.

An implementation of a virtual patient record using Web services.

Virtual patient records provide a means for integrated access to patient information that may be scattered around different healthcare settings. Within the boundaries of a health district providing all levels of care, this concept can be implemented in a corporate Intranet environment to support longitudinal patient care activities across the participating healthcare providers. In this context, a virtual patient record implementation enables autonomous healthcare providers to operate in a cooperative working environment and apply continuity of care. Workflow and web services technologies provide an appropriate infrastructure for satisfying collaboration and coordination requirements by integrating heterogeneous healthcare applications and by automatically routing the medical information needed to authorized actors in a healthcare process. This paper presents a virtual patient record architecture that allows integrating geographically dispersed medical information within a health district and enhancing collaboration and coordination of authorized workgroups using workflow and web services technologies. An implementation of the proposed architecture is also presented.

Developing a virtual patient record as a web-based workflow system.

A search engine for virtual patient records.

Virtual patient records provide a means for integrated access to patient information that may be scattered around different healthcare settings. Within the boundaries of a health district providing all levels of care, this concept can be implemented in an Intranet environment to support longitudinal patient care activities across the participating healthcare providers. Since medical information is stored on multiple Intranet sites in various forms (e.g. codified data, transcribed documents, and images), a suite of appropriate tools is needed to enable access to such information in combined form. In most cases, however, access to medical information should be restricted to authorized users. To serve this purpose, a prototype search engine incorporating an authorization and access control functionality has been developed and presented in this paper. The system is based on the signature file access method and an experimental implementation written in JAVA is also described.

A workflow-based approach to virtual patient record security.

Virtual patient records provide a means for integrated access to patient information that may be scattered around different healthcare organizations (or hospital departments). As Intranets provide, among others, secure access to medical information, they constitute an appropriate technological infrastructure for a virtual patient record implementation. In such cases, a security policy can be enforced by combining the security features of the Intranet with the security features of the intraorganizational systems. However, when a workflow system is implemented to automate interorganizational healthcare processes, an additional security layer is needed. An authorization architecture that serves this purpose is presented in this paper.
