Ontology
John, EMR and HIPAA
“I recently started to think about some of the implications associated with multiple languages in an EHR. One of my readers asked me how EHR vendors correlated data from those charting in Spanish and those charting in English. My first response to this question was, “How many doctors chart in Spanish?” Yes, this was a very US centric response since obviously I know that almost all of the doctors in Latin America and other Spanish speaking countries chart in Spanish, but I wonder how many doctors in the US chart in Spanish. I expect the answer is A LOT more than I realize.

Although the goal of achieving semantic interoperability of Electronic Health Records (EHRs) is pursued by many researchers, it has not been accomplished yet. In this paper we present a proposal that smoothes out the way towards the achievement of that goal. In particular our work focuses on medical diagnoses statements. In summary the main contributions of our ontology-based proposal are the following: First, it includes a canonical ontology whose EHR-related terms focus on semantic aspects.

Clinical Archetypes provide a means for health professionals to design what should be communicated as part of an Electronic Health Record (EHR). An ever-growing number of archetype definitions follow this health information modelling approach, and this international archetype resource will eventually cover a large number of clinical concepts. On the other hand, Clinical Terminology systems that can be referenced by archetypes also have a wide coverage over many types of health-care information.

Possibly the most important requirement to support co-operative work among health professionals and institutions is the ability of sharing EHRs in a meaningful way, and it is widely acknowledged that standardization of data and concepts is a prerequisite to achieve semantic interoperability in any domain. Different international organizations are working on the definition of EHR architectures but the lack of tools that implement them hinders their broad adoption. In this paper we present ResearchEHR, a software platform whose objective is to facilitate the practical application of EHR standards as a way of reaching the desired semantic interoperability.

With the exploding growth of the web, health websites have become a dominant force in the realm of health care. Technically savvy patients have been using the web not only to self inform but to self diagnose. In this paper we examine the trust relationship between humans and health websites by outlining the existing literature on trust in health websites. A total of 49 papers were examined using a meta-analytical framework.

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.

Objectives
(a) To determine the extent and range of errors and issues in the Systematised Nomenclature of Medicine – Clinical Terms (SNOMED CT) hierarchies as they affect two practical projects. (b) To determine the origin of issues raised and propose methods to address them.
Methods
The hierarchies for concepts in the Core Problem List Subset published by the Unified Medical Language System were examined for their appropriateness in two applications. Anomalies were traced to their source to determine whether they were simple local errors, systematic inferences propagated by SNOMED’s classification process, or the result of problems with SNOMED’s schemas. Conclusions were confirmed by showing that altering the root cause and reclassifying had the intended effects, and not others.

“During an ICMCC board dinner early 2005, Prof. Swamy Laxminarayan and I realized that the best way to solve the problem of unvalidated information on the internet was to link information from an EHR to health information platforms created by professional, reliable sources. The trick to do this was to base both the EHR and the information platform on the same coding/ontology standards like SNOMED, ICD and LOINC.

“Of the above, I think only point 2 might need an addition to openEHR. I think a very simple null-flavour vocabulary is preferable to the HL7 one, because the latter includes concepts that are very general with others that are very specific, and also does not achieve mutual exclusion.

Objectives:
We examine the potential of archetype patterns for upper-level ontology development in health information systems (HISs).
Methods:
Archetype patterns, based on the integration of archetype concepts and design patterns, are conceptualized and developed for ontology in the HIS domain. The UML provides the underlying modeling support.

Objectives:
Biomedical ontologies have been very successful in structuring knowledge for many different applications, receiving widespread praise for their utility and potential. Yet, the role of computational ontologies in scientific research, as opposed to knowledge management applications, has not been extensively discussed. We aim to stimulate further discussion on the advantages and challenges presented by biomedical ontologies from a scientific perspective.

“A vast computer based glossary of healthcare terms culled from so-called e-health tools, medical news sites, telemedicine applications, home care-management systems, internet-based public health records, and even health-oriented and medical blogs could help improve the relationship between patients and healthcare workers, according to research published in the International Journal of Electronic Healthcare.

Patient-centred healthcare subscribes to the belief that the patient has strengths, values and experiences that are important in the healthcare experience and relationship between those providing care and the patient. It requires patients to have the ability to obtain and understand health information, and make appropriate health decisions. The main problem here is that though the e-health applications provide patients and consumer with access to health information, each application is still individually used and the used and produced information remains within each system.

“At Aridhia we’ve begun to review and explore clinical ontologies. The ongoing research of specific ontologies has enabled us to begin the process of designing a healthcare domain specific semantic store that will allow components of the Aridhia health informatics platform to be referenced. Our goal is to develop a reference system that is beneficial to a wide range of healthcare professionals and can be used across many dynamic, clinical applications.

Ontologies can assist with translating information from an electronic health record to a clinical practice guideline and reformatting it into a compliance report. A 2009 literature search reviews publications on the use of ontologies to support automated reporting of compliance with clinical practice guidelines via electronic health records. Research stage, data-pulling capabilities, ontologies used, and issues raised are some of the comparative data pulled from 13 articles from the literature review results. Suggestions for further research are given.
