Web application for data exchange and follow-up in Heart Rate Turbulence

Cardiovascular risk stratification is widely used in clinical practice. Heart Rate Turbulence (HRT) is an example of a sudden cardiac death prediction index with clear and concise guidelines. We developed a web application based on a previously built HRT archetype for data exchange and follow-up for the HRT domain. The goal was to build a web tool to collect HRT related data from different HIS to clinical decision support. CEN/ISO EN13606 standard aims to define an information architecture for communicating EHR between heterogeneous systems. It is based on a dual model that defines separation between information and knowledge. The information is supported by a Reference Model containing the basic entities for representing any information of a specific domain. The knowledge is supported by an Archetype Model, a structured and constrained combination of entities from a Reference Model that represents a particular clinical concept. The nodes (clinical terms) and constraints (such as ranges of allowed values) of the built HRT archetype are used to define this domain in the web application. This web application not only allows to collect and manage HRT data, but also it provides functionalities like editing or viewing the information related to a patient. HRT follow-up to be used by the clinical community independently of technical limitations is obtained by combining web technologies and archetypes.
