Standardized Representation of Medical Data in AAL Applications

The Personal Healthcare Monitoring Report (PHMR) is a document format for representing measurements based on the HL7 Clinical Document Architecture (CDA), and thus a suitable document type for the storage of data from Ambient Assisted Living (AAL) applications. However, the characteristic of medical data in AAL applications differs fundamentally from the established view on medical data. Whereas clinical data are mostly single point measurements taken under well-controlled conditions in hospital, medical data in AAL applications are continuous, of a low sensor quality and often represent dynamic activities of human behaviour. This leads to a different representation of data in structured format.
