BACKGROUND Exchange of Electronic Health Record (EHR) data between systems from different suppliers is a major challenge. EHR communication based on archetype methodology has been developed by openEHR and CEN/ISO. The experience of using archetypes in deployed EHR systems is quite limited today. Currently deployed EHR systems with large user bases have(More)
BACKGROUND EHR systems are widely used in hospitals and primary care centres but it is usually difficult to share information and to collect patient data for clinical research. This is partly due to the different proprietary information models and inconsistent data quality. Our objective was to provide a more flexible solution enabling the clinicians to(More)
The translation and localization of SNOMED CT (Systematized Nomenclature of Medicine - Clinical Terms) have been initiated in a few countries. In Sweden, we conducted the first evaluation of this terminology in a project called REFTERM in which we also developed a software tool which could handle a large scale translation with a number of translators and(More)
With the introduction of EHR two-level modelling and archetype methodologies pioneered by openEHR and standardized by CEN/ISO, we are one step closer to semantic interoperability and future-proof adaptive healthcare information systems. Along with the opportunities, there are also challenges. Archetypes provide the full semantics of EHR data explicitly to(More)
In addition to the meaning as Health Informatics Society of Australia, HISA is the acronym used for the new European Standard: Health Informatics - Service Architecture. This EN 12967 standard has been developed by CEN - the federation of 29 national standards bodies in Europe. This standard defines the essential elements of a Service Oriented Architecture(More)
1. Foreword This is the third draft of a paper that aims to clarify the apparent contradictions in the views presented in certain standards and other specifications of health informatics systems, contradictions which come to light when the latter are evaluated from the perspective of realist philosophy. One of the origins of this document was Klein's(More)
Computer support for health care started in Sweden in the mid-1960s, with a series of pilot tests using clinical records at the Karolinska Hospital. This had very little impact in health care due to its limited volume and scope. In addition, the first automation of chemistry laboratories that created many benefits in the form of increased efficiency from(More)
In many countries today, an important challenge for health care is the fact that the population is mixed as regards cultural background and not the least with regard to preferred language. In our country Sweden almost 20% of the population has some connection to another country and many patients seeking health care do not have sufficient mastering of the(More)
Smart glasses, defined as a computerized communicator with a transparent screen and a video camera, wearable as a pair of glasses, have started to be tested for a variety of health related applications. This poster reviews some of the early experiences and gives a series of proposals for possible uses in medicine with a particular emphasis on medical(More)
