A semantic framework to protect the privacy of Electronic Health Records with non-numerical attributes

Martínez S et al, Journal of biomedical informatics, 2012

Structured patient data like Electronic Health Records (EHRs) are a valuable source for clinical research. However, the sensitive nature of such information requires some anonymisation procedure to be applied before releasing the data to third parties. Several studies have shown that the removal of identifying attributes, like the Social Security Number, is not enough to obtain an anonymous data file, since unique combinations of other attributes as for example, rare diagnoses and personalised treatments, may lead to patient’s identity disclosure. To tackle this problem, Statistical Disclosure Control (SDC) methods have been proposed to mask sensitive attributes while preserving, up to a certain degree, the utility of anonymised data. Most of these methods focus on continuous-scale numerical data.

Empowering citizens with access control mechanisms to their personal health resources

Calvillo J et al, International Journal of Medical Informatics, 2012

Background
Advancements in information and communication technologies have allowed the development of new approaches to the management and use of healthcare resources. Nowadays it is possible to address complex issues such as meaningful access to distributed data or communication and understanding among heterogeneous systems. As a consequence, the discussion focuses on the administration of the whole set of resources providing knowledge about a single subject of care (SoC). New trends make the SoC administrator and responsible for all these elements (related to his/her demographic data, health, well-being, social conditions, etc.) and s/he is granted the ability of controlling access to them by third parties. The subject of care exchanges his/her passive role without any decision capacity for an active one allowing to control who accesses what.

Archetype Sub-Ontology: Improving Constraint-based Clinical Knowledge Model in Electronic Health Records

Sari AK et al, Knowledge-Based Systems, 2011

The global effort in the standardization of electronic health records has driven the need for a model to allow medical practitioners to interact with the newly standardized medical information system by focusing on the actual medical concepts/processes rather than the underlying data representations. An archetype has been introduced as a model that represents functional health concepts or processes such as admission record, which enables capturing all information relevant to the processes transparently to the users. However, it is necessary to ensure that the archetypes capture accurately all information relevant to the archetype concepts. Therefore, a semantic backbone is required for each of the archetype.

Ontology-driven health information systems architectures

Blobel B, Oemig F. Medical Informatics in a United and Healthy Europe, 2009

Following an architecture vision such as the Generic Component Model (GCM) architecture framework, health information systems for supporting personalized care have to be based on a component-oriented architecture. Representing concepts and their interrelations, the GCM perspectives system architecture, domains, and development process can be described by the domains’ ontologies.

[Information systems in health and health indicators: an integrating perspective]

Canela-Soler, Jaume et al, Medicina Clínica, 134 Suppl 1

Health Information Systems (HIS) are the core support to decision-making in health organizations. Within HIS, health indicators (HI) reflect, numerically, events measured in the health-illness continuum. The integrated health information system is intended to standardize, integrate and organize all the information available in health information systems through an accessible and secure repository, and to conveniently distribute information for decision-making. To standardize information it is necessary to define standards and semantic information to enable us to identify concepts and relate them uniquely to each other.

Ensuring the Continuity of Care of Cardiorespiratory Diseases at Home. Monitoring Equipment and Medical Data Exchange over Semantically Annotated Web Services

Spyropoulos, B. et al, Methods of Information in Medicine, 49(2)

Objectives:
A significant portion of care related to cardiorespiratory diseases is provided at home, usually but not exclusively, after the discharge of a patient from hospital. It is the purpose of the present study to present the technical means which we have developed, in order to support the adaptation of the continuity of care of cardiorespiratory diseases at home.

Meaningful use of pharmacogenomics in health records: semantics should be made explicit

Shabo Shvo, Amnon, Pharmacogenomics, 11(1)

The recent emphasis on ‘meaningful use’ of electronic health records in health information technology reforms (e.g., as in the US stimulus package) can leverage the pharmacogenomics field. In order for clinical trials outcomes, based on pharmacogenomics research, to be meaningfully and effectively used in clinical practice there is a need to make health semantics explicit. Often, semantics is merely implicit in both the research and practice worlds and is buried in unstructured and disconnected descriptions of the data or just in the heads of human experts.

Health care process and workflow in continuity of care

Mennerat, François et al, Medical Informatics in a United and Healthy Europe, 2009

Basically, the workshop aims to raise and collect input to Part 2 (”Health care process and workflow”), currently under development, of the European standard EN 13940 “Health informatics – System of concepts to support continuity of care”, the general objective of which is to enable communication at the semantic level between information systems in health care in the perspective of continuity of care. Its scope encompasses identifying the various processes and process objects involved, taking into consideration resource management aspects, responsibilities of health care providers, and means for patients’ participation.

Enhanced semantic interpretability by healthcare standards profiling

López, Diego M, and Bernd Blobel, eHealth Beyond the Horizon - Get IT There, 2008

Several current healthcare standards support semantic interoperability. These standards are far to be completely adopted in health information system development, however. The objective of this paper is to provide a method and necessary tooling for reusing healthcare standards by exploiting the extensibility mechanisms of UML, by that way supporting the development of semantically interoperable systems and components. The method identifies first the models and tasks in the software development process in which health care standards can be reused.

Improving Healthcare Middleware Standards with Semantic methods and technologies

Román, Isabel et al, Medical and Care Compunetics 5, 2008

A critical issue in healthcare informatics is to facilitate the integration and interoperability of applications. This goal can be achieved through an open architecture based on a middleware independent from specific applications; useful for working with existing systems, as well as for the integration of new systems. Several standard organizations are making efforts toward this target.
