Providing a comprehensive set of relevant information at the point of care is crucial for making correct clinical decisions in a timely manner. Retrieval of scenario specific information from an extensive electronic health record (EHR) is a tedious, time consuming and error prone task. In this paper, we propose a model and a technique for extracting relevant clinical information with respect to the...
In the new network-centric healthcare IT environment, standardization of information representation, organization and dissemination is the first step towards achieving semantic interoperability among heterogeneous systems. In this paper, we discuss roadblocks encountered in a real-world project to integrate two disparate healthcare systems based on HL7 v3 standards. We propose a tool-assisted approach...
The variety and heterogeneity of legacy systems at the application level have contributed to the complexity of interoperability provision among different application domains. In this context, most research activities are focused towards standardization and interoperability among the legacy systems within the same domain. However, an emerging challenge is to address the communication of information...
International standardization in information representation, organization, and dissemination are meant to eliminate the discrepancies in communication among participating organizations and institutions in a particular domain. The management of domain information will then allow different participants to integrate their legacy information or application servers to a nation-wide network and use widely...
Privacy and security are critical requirements for using patient profiles in distributed healthcare environments. The amalgamation of new information technology with traditional healthcare workflows for sharing patient profiles has made the entire system vulnerable to security and privacy breaches. In this paper we present a novel access control model based on a framework designed for data and service...
View-based software development is well adopted in for techniques still consider a single view of a software system with restricted scope of analysis. In this paper, we propose a novel approach that amalgamates dynamic and static views of a software system. The dynamic view is represented through profiling information that is extracted from executing a set of task scenarios that cover frequently used...
Large organizations in various information domains are constantly facing the challenges of growing size, new business requirements, and customer demands for service agility. As an example, in the healthcare domain provision of unique electronic health record systems (EHR) for patient identification and health history, integration of regional systems into a nation-wide system, information and service...
Computer based clinical guidelines have been developed to help caregivers in practicing medicine. GLIF3 (Guideline Interchange Format 3) is one of several standards that specify the structure for defining guideline models. The decision making steps within the GLIF3 guidelines are limited to evaluation of basic logic expressions. On the other hand, data mining analyses aim at building descriptive or...
Alborz is a multi-view, interactive, and wizard-based software architecture reconstruction and evaluation toolkit that takes advantage of the Eclipse plug-in technology to provide feature extensibility, and uses GXL format to interoperate with other reverse engineering tools. The current version of Alborz toolkit supports static and dynamic views of a software system. For the static view, the toolkit...
Software system analysis for extracting system functionality remains as a major problem in the reverse engineering literature and the early approaches mainly rely on static properties of software. In this paper, we propose a novel technique for dynamic analysis of software systems to identify the implementation of the software features that are specified through a number of feature-specific task scenarios...
In this paper we propose a knowledge management framework for distributed health care systems consisting of data- and knowledge-bases that contain patient data and mined knowledge from health care institutions. The framework takes advantage of data mining techniques, enabling technologies and standards to provide decision making support for the health care personnel. The application areas of the new...
