Care of chronic cardiac patients requires information interchange between patients’ homes, clinical environments and the Electronic Health Record (EHR).

Abstract

Care of chronic cardiac patients requires information interchange between patients’ homes, clinical environments and the Electronic Health Record (EHR). Standards are emerging to support clinical information collection, exchange and management and to overcome information fragmentation and actors delocalization. Heterogeneity of information sources at patients’ homes calls for open solutions to collect and accommodate multi-domain information, including environmental data. Based on the experience gained in a European Research Program, this paper presents an integrated and open approach for clinical data interchange in cardiac telemonitoring applications. This interchange is supported by the use of standards following the indications provided by the national authorities of the countries involved. Taking into account the requirements provided by the medical staff involved in the project the authors designed and implemented a prototypal middleware, based on a Service Oriented Architecture (SOA) approach, to give a structured and robust tool to CHF (Congestive Heart Failure) patients for their personalized telemonitoring. The middleware is represented by a Health Record Management Service (HRMS), whose interface is compliant to the HSSP (Healthcare Services Specification Project) RLUS (Retrieve, Locate and Update Service) standard (Level 0), which allows communication between the agents involved through the exchange of CDA R2 (Clinical Document Architecture Release 2) documents. Three performance tests were carried out and showed that the prototype completely fulfilled all requirements indicated by the medical staff, however certain aspects, such as authentication, security and scalability, should be deeply analyzed within a future engineering phase.
