- See LOINC collaboration with IEEE for information on the Medical Device Code Mapping Table, which provides linkages between LOINC terms and IEEE EMB/11073 standard.
- ISO/IEEE 11073 is a family of standards for point-of-care medical device communication, with specific standards within the 11073 family that support collection of vital signs from medical devices, including:
- IEEE P11073-10404: Device Specialization - Pulse Oximeter
- IEEE 11073-10406: Device Specialization - Basic electrocardigraph (ECG)
- IEEE P11073-10407: Device Specialization - Blood Pressure Monitor
- IEEE 11073-10408: Device Specialization - Thermometer
- IEEE P11073-10415: Device Specialization - Weighing Scale
- IEEE 11073-10417: Device Specialization - Glucose Meter
- IEEE 11073-10201: Implantable Cardiac Devices

Preserving Clinical Context
General Comments: USCDI specifies lots of clinical data classes and data elements- Resolving to myriad de-coupled fragments
- With vanishingly little focus on:
- Clinical context and vital inter-relationships, e.g., between problems, diagnoses, complaints, symptoms, encounters, history and physical findings, allergies, medications, vaccinations, assessments, goals/objectives, clinical decisions, orders, results, diagnostic procedures, interventions, observations, treatments/therapies, referrals, consults, outcomes, protocols, care plans and status...
- Elements and context + purpose of capture: e.g., blood pressure, its measurement (systolic, diastolic), its unit of measure (mm/Hg), its reason for capture, its context of capture (sampling site, sampling method, patient position, at rest/during/post exercise...
It is crucial to consider, determine and resolve how clinical content and context are bound together and preserved in USCDI. The ultimate end user (often a clinician) must be able to readily discern context and inter-relationships – otherwise USCDI places an undue (and often unresolvable) burden on this user. Only the source EHR/HIT system can structure clinical content and context properly. Once data is stuffed into the USCDI framework and related exchange artifact (e.g., FHIR resources) this opportunity is forever lost.
