Semantization of the Electronic Medical Record

In recent years, in the health field, the value of having complete Electronic Medical Records has been seen and a lot of work has been done to improve and implement them in the clinical and hospital field. Specifically, a lot of work has been done at the level of interoperability, so that the EHR of a patient who moves through different health systems or hospitals can continue to be valid in the new destination. Different EHR standards have been defined, such as CEN/ISO EN13606, HL7 (RIM, CDA) and OpenEHR, where the characteristics that an EHR must meet both at the communication level with other EHRs and at the structure level have been marked. .


The results obtained at the level of both technological and medical research have been very positive, and although at the operational level these types of systems have not yet been fully transferred to all hospital environments, today they are a reality at the product level and there are a market in continuous growth that is improving health systems both nationally and internationally.

However, this vision of EHR does not take full advantage of the potential offered by these systems. In particular, all these patient records stored in the EHR implicitly reflect clinical decisions made by health professionals who have participated in the medical care offered to the patient, as well as the results of said decisions:


  • What parameters have been used for each patient for the decisions made about what tests to perform, what treatments to prescribe, what interventions to perform.

  • What criteria have been followed in those decisions (if the criteria have followed the guidelines set by the clinical guidelines or protocols of the corresponding health institutions)

  • What has been the result of the decisions made about the patient (effect of the treatments provided, fulfillment of the objectives of providing a specific treatment).

  • In this way, the exploitation of this information that is implicit in the EHR systems could also serve to improve the knowledge we have about the mechanisms of a disease or the effectiveness of the treatments provided.  

The SemanHis project wants to move EHR systems from being mere repositories of data to repositories of knowledge, which could serve to improve future decisions made on a patient. To this end, it is proposed to carry out a Semantic Clinical History that allows the extraction of implicit knowledge in the history and its exploitation both for the clinical field and for hospital management. Specifically, the development of a new version of the Hygehos Electronic Medical Record is proposed, shared by both companies in the consortium: a semantic Hygehos with the ability to offer decision support services.

Asunción Clínica and the VicomTech IK4 technology center work on the SemanHIS project and it is included in the Hazitek program for the Development of Business R&D of the Department of Economic Development and Infrastructure of the Basque Government.  

O bjectives

  • Develop a system that allows the exploitation of the information contained in the EHR of a health system, hospital and medical center with a secondary purpose, apart from storing all the medical history and interactions of a patient:

  • The evaluation of the effectiveness of the clinical practice carried out.

  • The explanation of the decision criteria carried out (vs the criteria established by the clinical guidelines or protocols).

  • The identification of patients who meet certain characteristics (for example, for the recruitment of patients in clinical studies).

  • Extract knowledge of EHR in the field of chronic patients.

  • Develop a prototype of the system (pre-commercial) that can serve the consortium participants to improve their commercial and research activity.
