- ItemAndroid-based access to holistic emergency care record.(2013-07-04) Koufi, Vassiliki; Malamateniou, Flora; Prentza, Andriana; Vassilacopoulos, GeorgeThis paper is concerned with the development of an Emergency Medical Services EMS system which interfaces with a Holistic Emergency Care Record HECR that aims at managing emergency care holistically by supporting EMS processes and is accessible by Android enabled mobile devices
- ItemAn Android-enabled mobile framework for ensuring quality of life through patient-centric care.(2012-08-09) Koufi, Vassiliki; Malamateniou, Flora; Vassilacopoulos, GeorgeThe drive to achieve excellence in healthcare delivery while containing costs underlies the need for a new generation of applications which facilitate the realization of a patient centric care model Under this emerging care model healthcare delivery can be integrated across the continuum of services from prevention to follow up and care can be coordinated across all settings With care moving out into the community health systems require real time information to deliver coordinated care to patients The integration of leading edge technologies such as mobile technology with Personal Health Records PHRs can meet this requirement by making comprehensive and unified health information available to authorized users at any point of care or decision making through familiar environments such as Google s Android This paper presents a framework that provides ubiquitous access to patients PHRs via Android enabled mobile devices Where possible health information access and management is performed in a transparent way thus enabling healthcare professionals to devote more time on practicing medicine and patients to manage their own health with the least possible intervention This depends heavily on the context which is collected by both Android specific core system services and special purpose software agents with the latter being also responsible for preserving PHR data privacy
- ItemContext-aware access control for pervasive access to process-based healthcare systems.(2008-05-19) Koufi, Vassiliki; Vassilacopoulos, GeorgeHealthcare is an increasingly collaborative enterprise involving a broad range of healthcare services provided by many individuals and organizations Grid technology has been widely recognized as a means for integrating disparate computing resources in the healthcare field Moreover Grid portal applications can be developed on a wireless and mobile infrastructure to execute healthcare processes which in turn can provide remote access to Grid database services Such an environment provides ubiquitous and pervasive access to integrated healthcare services at the point of care thus improving healthcare quality In such environments the ability to provide an effective access control mechanism that meets the requirement of the least privilege principle is essential Adherence to the least privilege principle requires continuous adjustments of user permissions in order to adapt to the current situation This paper presents a context aware access control mechanism for HDGPortal a Grid portal application which provides access to workflow based healthcare processes using wireless Personal Digital Assistants The proposed mechanism builds upon and enhances security mechanisms provided by the Grid Security Infrastructure It provides tight just in time permissions so that authorized users get access to specific objects according to the current context These permissions are subject to continuous adjustments triggered by the changing context Thus the risk of compromising information integrity during task executions is reduced
- ItemA sophisticated mechanism for enabling real-time mobile access to PHR data.(2013-07-04) Koufi, Vassiliki; Malamateniou, Flora; Vassilacopoulos, GeorgeFaced with rapid changes such as growing complexity in care delivery health systems nowadays fall short in their ability to translate knowledge into practice Mobile technology holds enormous potential for transforming healthcare delivery systems which currently involve cumbersome processes that slow down care and decrease rather than improve safety However the limited computing energy and information storage capabilities of mobile devices are hampering their ability to support increasingly sophisticated applications required by certain application fields such as healthcare This paper is concerned with a framework which provides ubiquitous mobile access to comprehensive health information at any point of care or decision making in a way that efficient utilization of mobile device resources is achieved To this end a cloud based push messaging mechanism is utilized which draws upon and enhances Google Cloud Messaging service
