Modeling and Recognizing Policy Conflicts with Resource Access Requests on Protected Health Information

This article discusses potential clashes between different types of security policies that regulate resource access requests on clinical patient data in hospitals by employees. Attribute-based Access Control (ABAC) is proposed as a proper means for such regulation. A proper representation of ABAC policies must include a handling of policy attributes among different policy types. In this article, we propose a semantic policy model with predefined policy conflict categories. A conformance verification function detects erroneous, clashing or mutually susceptible rules early during the policy planning phase. The model and conflicts are used in a conceptual application environment and evaluated in a technical experiment during an interoperability test event

A Description Model for Policy Conflicts for Managing Access to Health Information

Abstract. For a better business and IT alignment in hospitals an ontology-based description model for policy conflicts is introduced. Such a model is a necessary prerequisite for the subsequently domain-specific policy conflict handling as a hospital information management related activity

Aligning ABAC policies with information security policies using controlled vocabulary

Attribute-based Access Control (ABAC) policies are based on mutually processable policy attributes. Assigned permissions in such policies need to be reflected or combined with organizational constraints. Best practice in information security dictates having the operational need to access a particular information artifact independent from the function of the specific application systems. Consequently, any policy regulating the behaviour towards information access must adhere to a minimum degree of mutual semantic expressiveness to be combined and processed with the matching ABAC policy. We show how to detect policy attribute conflicts between ABAC policies and information access policies by means of controlled vocabulary and Semantic Web technologies

Open Identity Summit 2015: 10. - 11.11.2015, Berlin, Germany

Open standards and interfaces as well as open source technologies play a central role in the current identity management landscape as well as in emerging future scenarios in the area of electronic identification and trustworthy end-to-end encryption for example. While there are already plenty of successful applications in which those techniques are used to safeguard the authenticity, integrity and confidentiality, there are still many closely related areas which demand further research. The aim of the „Open Identity Summit 2015“ is to link practical experiences and requirements with academic innovations. Focus areas of this event are research and applications in the area of Identity Management, Trust Services, Open Source, end-to-end encryption and Cloud Computing

Evaluation einer elektronisch unterstützten pflegerischen Überleitung zwischen Krankenhaus und Pflegeheim unter Nutzung einer Test-Telematikinfrastruktur: eine Fallanalyse

Background: Improper information transmission can lead to compromised patient safety and quality of life when patients are transferred from one setting to another. Electronic instruments may improve this situation, however, they are rarely used. Objective: The aim of this study therefore was to investigate the technical and organizational feasibility, usability, usefulness and completeness of an electronic instrument that is based on the German HL7 CDA standard for eNursing Summaries.Materials and methods: To this end, a test health telematics infrastructure, which included the German electronic health card, was established and nursing summary application was developed that allowed summary documents to be communicated between a hospital and a nursing home. The users were asked to evaluate the usability of the nursing summary application as well as to compare the usefulness and completeness of electronically and paper transmitted information.Results: This study demonstrated the feasibility of implementing an electronic nursing summary application that was based on the German HL7 CDA standard eNursing Summary and that was integrated in a test health telematics infrastructure. It could also be shown that the users rated this application as usable and that electronically supported patient transfers were superior to paper based ones. The use of the German electronic health card was regarded as a barrier by the users.Discussion: This study emphasizes the feasibility, relevance and barriers of electronically supported transfers of patients with nursing needs. Nurses working in hospitals and long-term care can integrate an application based on the HL7 CDA Standard ePfgebericht into their working processes and get better and more complete information. To ensure continuity of care in a sustainable manner in the future, the German HL7 CDA based eNursing Summary standard should become part of the German telematics infrastructure

Evaluating a proof-of-concept approach of the german health telematics infrastructure in the context of discharge management

Although national eHealth strategies have existed now for more than a decade in many countries, they have been implemented with varying success. In Germany, the eHealth strategy so far has resulted in a roll out of electronic health cards for all citizens in the statutory health insurance, but in no clinically meaningful IT-applications. The aim of this study was to test the technical and organisation feasibility, usability, and utility of an eDischarge application embedded into a laboratory Health Telematics Infrastructure (TI). The tests embraced the exchange of eDischarge summaries based on the multiprofessional HL7 eNursing Summary standard between a municipal hospital and a nursing home. All in all, 36 transmissions of electronic discharge documents took place. They demonstrated the technical-organisation feasibility and resulted in moderate usability ratings. A comparison between eDischarge and paper-based summaries hinted at higher ratings of utility and information completeness for eDischarges. Despite problems with handling the electronic health card, the proof-of-concept for the first clinically meaningful IT-application in the German Health TI could be regarded as successful
