Change Log

Page standards status: Informative

Major Updates in version 2.0.0 since version 1.1.0

Standards Foundation Updates

1. IEEE 11073-10206 Support: The IG now focuses on comprehensive support for IEEE 11073-10206 ACOM (Abstract Communication Object Model) specifications, moving away from the original IEEE 11073-20601 focus.

2. Bluetooth GHS Integration: Added support for Bluetooth Generic Health Sensor (GHS) specifications, broadening the scope of supported personal health devices.

Documentation and Profile Improvements

1. Enhanced Profile Consumer Documentation: Significantly rewritten consumer guidance with better explanations of how to use PHD-generated FHIR resources, including clearer guidance on measurement types, status handling, and device information.

2. Reorganized Technical Content:

   • Consolidated IEEE 11073 FLOAT/SFLOAT documentation
   • Integrated coincident timestamp content into profile documentation
   • Updated guidance for better clarity

Terminology Updates

1. Code System Migration: Updated to use official HL7 terminology server versions of ASN1ToHL7 and Continua Device Identifiers code systems.

2. Missing MDC Codes: Added support for MDC codes not yet available in standard terminology, including Spirometer device specialization.

Profile Enhancements

1. IEEE 11073-10206 Mapping: Added formal mappings showing how ACOM elements map to FHIR elements in the PhdDeviceMetric profile.

2. Profile Documentation: Enhanced explanations across all profiles with clearer guidance on when elements are used and how they relate to IEEE 11073 standards.

Example Updates

1. Improved Examples: Updated observation examples with better documentation and clarifications about identifier usage in real implementations.

Content Quality Improvements

The changes focus on improving documentation quality, clarifying the relationship between IEEE 11073 standards and FHIR profiles, and ensuring terminology consistency. The updates make the IG more consumable for implementers while expanding support for both IEEE 11073-10206 ACOM and Bluetooth GHS specifications.
