This Implementation Guide defines the use of FHIR resources to convey measurements and supporting data
from acute care point-of-care medical devices (PoCD) intended for use by qualified professional to receiving systems for electronic medical records,
clinical decision support, and medical data archiving for aggregate quality measurement and research purposes.
It adds "deep metadata for device observations".
Key goals include supplementing the measurement values in an Observation resource with full provenance for traceability, and with
fuller details of device architecture and dynamically changing attributes such as
calibration history and battery state than is provided for in a FHIR Observation resource. This guide is intended to supplement — not replace — existing approaches such as HL7v2/IHE PCD-01 for communicating device data to device observation consumers.
The next release of this Guide intends to cover physiological and technical alerts from medical devices. Another related implementation guide focuses on home-based personal health devices.
The scope of this Implementation Guide is a FHIR-based treatment of quantitative and qualitative observations communicated from point-of-care medical devices. Devices without communications capabilities are out of scope. Imaging devices are also out of scope. Personal devices intented for home health and fitness purposes to be used by non-professional users are excluded because they are covered by a related Implementation Guide. See below.
This Implementation Guide is intended for
The "Getting Started" pages provide a general introduction to the concepts and approach used in this Implementation Guide, relevant to all potential users including clinical staff and system implementers. These pages include:
The Implementation Guide is organized around two main categories of implementers:
This Implementation Guide covers material related to work in other projects and guides including the Personal Health Device Implementation Guide, and IHE Patient Care Device (PCD) profiles.
The Personal Health Device Implementation guide focuses on wellness and chronic disease management devices used mainly by nonprofessionals in home and exercise settings.
This Point-of-Care Device Implementation Guide is focused on acute-care devices for professional use mainly in healthcare delivery facilities.
The Personal Health Device and Point-of-Care Device guides both use information models and nomenclature from the IEEE 11073 Medical Device Communications series of standards and the guides for these two kinds of devices are being developed cooperatively in the Devices On FHIR project with a goal of consistency and ease of use by receiving systems.
The IHE PCD domain has developed profiles for conveying acute care device data with context using HL7 V2. The base information system and nomenclature are based on the IEEE 11073 Medical Device Communications standards, also used in this FHIR Implementation Guide.
These profiles cover Device Enterprise Communications (DEC), reporting device observations to enterprise systems including near-real-time charting to electronic medical records, clinical decision support systems and patient data archive systems. That is similar to the scope of this FHIR Implementation Guide.
A planned future FHIR use case for the Devices on FHIR group is the near-real-time communication of physiological and technical alerts to clinicians, and internal device status and state transition information for systems designed to process such information. This is similar to IHE PCD Alert Communication Management (ACM) and Infusion Pump Event Communication (IPEC) profiles.
Other PCD profiles include Implantable Device Cardiac Observations (IDCO), Point-of-Care Infusion Verification (PIV) and Point-of-Care Identity Management (PCIM). Future versions of this Implementation Guide will extend scope to cover related functionality based on FHIR rather than HL7 V2.
The Observation resource is used to record data that is retrieved from a device. Some values that are
formalized in this resource are required to conform to the
Vital Signs Profile,
for example, heart rate or respiratory rate. Many of these are often provided by a PoCD patient-connected device.
It is possible that in rare cases using this Implementation Guide that a device or device gateway using only ISO/IEEE 11073 terminology codes may not have sufficient information to recognize a particular meaurement as within the the Vital Signs set and determine an equivalent LOINC code and UCUM unit code for the result. Therefor, provisions must be made to correctly make the mapping for these terms from 11073 to LOINC UCUM, and to ensure that this is done at the earliest possible point.
This is an area of necessary coordination between this IG and the Vital Signs Profile.
This Implementation Guide addresses device data modeling and representation in FHIR resources, but implementers must also consider the connectivity behavior and network characteristics required for safe and effective PoCD deployments. The following considerations are important for understanding how to deploy and operate PoCD systems in practice.
Point-of-care devices can generate data at widely varying rates. Some devices produce observations at discrete intervals (e.g., every few seconds or minutes), while others may produce continuous waveform data or high-frequency measurements requiring substantial bandwidth. Implementation planning must account for:
Different clinical use cases require different connectivity patterns:
The choice of connectivity model should be guided by clinical requirements, network reliability, and system architecture.
The requirements for PoCD connectivity vary significantly by clinical context:
Intensive Care Unit (ICU) and Operating Room (OR): These settings typically demand real-time or near-real-time visibility of device data with high reliability. Network infrastructure is usually robust, and clinical staff are trained to interpret continuous device streams. Systems in these settings should support persistent connections and handle high-frequency data transmission.
General Hospital Wards and Acute Care Settings: Clinical needs for data vary by department and patient acuity. Some observations benefit from continuous monitoring while others can be recorded at intervals. System design should accommodate mixed connectivity models.
Home and Ambulatory Settings: These settings often have less reliable network connectivity and different clinical workflows. Data may be collected and stored locally on the device or gateway, then transmitted when connectivity is available.
Understanding these differences is essential for designing systems that safely and effectively integrate PoCD data into diverse clinical environments.
Clinical decision-making depends on understanding both the immediate values of device measurements and their historical context. Implementation selection must consider:
This Implementation Guide focuses on the data models and FHIR representation necessary for exchanging PoCD observations. As experience accumulates from prototype implementations and real-world deployments, further guidance on optimal connectivity patterns, throughput profiling, and operational practices for different clinical settings will be developed. The interaction between multiple implementations, including considerations of performance under different network conditions and clinical workflow integration, will inform future versions of this guide.
