Standard-compliant real-time transmission of ECGs: Harmonization of ISO/IEEE 11073-PHD and SCP-ECG

Abstract

Ambient assisted living and integrated care in an aging society is based on the vision of the lifelong Electronic Health Record calling for HealthCare Information Systems and medical device interoperability. For medical devices this aim can be achieved by the consistent implementation of harmonized international interoperability standards. The ISO/IEEE 11073 (x73) family of standards is a reference standard for medical device interoperability. In its Personal Health Device (PHD) version several devices have been included, but an ECG device specialization is not yet available. On the other hand, the SCP-ECG standard for short-term diagnostic ECGs (EN1064) has been recently approved as an international standard ISO/IEEE 11073-91064:2009. In this paper, the relationships between a proposed x73-PHD model for an ECG device and the fields of the SCP-ECG standard are investigated. A proof-of-concept implementation of the proposed x73-PHD ECG model is also presented, identifying open issues to be addressed by standards development for the wider interoperability adoption of x73-PHD standards.

Ambient Assisted Living Healthcare Frameworks, Platforms, Standards, and Quality Attributes

“…The ASTM F2761 defines requirements and procedures for design, verification and validation of integrated clinical environments incorporating model-based integration of systems. Similarly, the differences in medical device communication standards for ECG are investigated by Trigo et al [ 87 ]. They have proposed an x73-PHD model for an ECG device and evaluated other widely used ECG standards including, Standard Communication Protocol for Computer-assisted Electrocardiography (SCP-ECG), HL7 Annotated Electrocardiogram (aECG), Medical Waveform Format Encoding Rules (MFER), and Digital Imaging and Communications in Medicine (DICOM).…”

Using off-the-Shelf Medical Devices for Biomedical Signal Monitoring in a Telemedicine System for Emergency Medical Services

“…According to their clinical trials, 4 seconds is the maximum acceptable delay. Trigo et al [16] present a prototype implementation of real-time ECG transmission using the IEEE 11073 standards family, while harmonization for the ECG device specialization was still ongoing. This prototype is not clinically evaluated, but demonstrates general feasibility.…”

“…The majority of AAL related research studies are trying to achieve interoperability and integration [13]. Others studies focus on medical device communication and electronic health record standards [8,14]. Besides, wireless sensor networks are also investigated for AAL usage [15].…”
