PHD Profiles

Profiles for mapping 11073 20601 Personal Health Devices to FHIR resources

  •  PhdBaseObservation Observation elements that are common to all the Continua PHD Observation profiles
  •  PhdNumericObservation StructureDefinition for Observation Resources representing measurement data coming from a medical device where the measurement is number.
  •  PhdCompoundNumericObservation StructureDefinition for Observation Resources representing measurement data coming from a medical device where the measurement is described by a set of numbers such as the x, y, and x components of an acceleration.
  •  PhdCodedEnumerationObservation StructureDefinition for Observation Resources representing measurement data coming from a medical device where the measurement itself is an enumerated code.
  •  PhdBitsEnumerationObservation StructureDefinition for Observation Resources representing measurement data coming from a medical device where the measurement is an ASN1 BITS value.
  •  PhdRtsaObservation StructureDefinition for Observation Resources representing measurement data coming from a medical device where the measurement is a waveform.
  •  PhdStringEnumerationObservation StructureDefinition for Observation Resources representing measurement data coming from a medical device where the measurement itself is an enumerated human readable string.
  •  PhdCoincidentTimeStampObservation StructureDefinition for Observation Resources representing the coincident time stamp. This report is a measurement of the current time of the sensor at the current time of the PHG. The purpose of this observation is to record the difference in the time lines between the PHG and PHD and to be able to recover the original measurement time stamps reported by the PHD should the PHG correct them because the sensor clock is in error.
  •  PhdDevice StructureDefinition for the Device Resource representing a PHD
  •  PhgDevice StructureDefinition for the Device Resource representing a PHG (gateway)
  •  PhdPatient Structure definition for the patient information reported from personal health gateways (PHG)

Value Sets

Value Sets used and defined in this Implementation Guide

  •  CodeableConcept11073MDC Value set for those MDC attribute codes whose values are represented by CodeableConcepts. These codes are used as slicing discriminators.
  •  Quantity11073MDC Value set for those MDC attribute codes whose values are represented by Quantities. These codes are used as slicing discriminators.
  •  Range11073MDC Value set for those MDC attribute codes whose values are represented by Ranges. These codes are used as slicing discriminators.
  •  String11073MDC Value set for those MDC attribute codes whose values are represented by Strings. These codes are used as slicing discriminators.
  •  MDCnotObject Value set for those Observation component elements that come from compound and BITs measurements. These attributes come from several partitions but NOT the MDC Object partition. These codes are used as slicing discriminators to distinguish between those components that represent measurement values in the compound and ASN1 BITs profiles from those components providing additional information about the values. For example, the supplemental types would give an extra description about the measurement such as 'duration average' whereas the measurement itself might be acceleration values.
  •  ASN1attribute Value set for those Asn1ToHL7 codes whose PHD source is an attribute, such as the regulation status or time capabilities.
  •  ASN1measurement Value set for those Asn1ToHL7 codes whose source is a measurement attribute; one of the Enum-observed-value attributes.

Code Systems

Code Systems defined in this Implementation Guide

  •  ContinuaDeviceIdentifiers Codes that identify the device 'identifier', such as whether an EUI is a system id, Bluetooth address, or Ethernet MAC address
  •  ASN1ToHL7 Codes for the IEEE 11073 20601 BITs measurement bit values. For example, 150604.0 is the code for Mder bit 0 in measurement type 150604 which is a pulse oximeter device and sensor status. The description of that code is 'Indicates the device is not connected with the sensor'. This code system will grow as more BITs measurements are defined in specializations
  •  ContinuaHFS Codes for the Continua Health and Fitness interfaces
  •  ContinuaPHD Codes for the Continua certified PAN interfaces. These codes indicate that the respective platform has been certified for certain transports (Bluetooth, USB, Bluetooth Low Energy, ZigBee) and device specializations.

Capability Statements

Capability Statements defined in this Implementation Guide

  •  PhdServerCapabilityStatement Capability statement. This statement indicates what the server must support and accept to work with this Guide. Though the CapabilityStatement indicates, for example, that the server must support the Device resource, it does not mean the server must save the Device resource. The use case may only be interested in the Observation and Patient resources. What it does mean is that the server cannot generate an error when the PHG uploads a Device resource or references a Device resource that it has uploaded.

Examples

Examples of resources following the Implementation Guide Profiles

  •  Example of a first time Bundle upload This example shows a full transaction Bundle containing Patient, Device, and Observation resources. In subsequent uploads, the Patient and Device resources would not need to be present.
  •  Example of PHD Device This example PHD Device resource is referenced by other examples and is present for the validator.
  •  Example Bundled upload This example is an upload from a Bluetooth Low Energy Pulse oximeter device streaming data. In this case the gateway has previously uploaded measurements and saved the logical ids of the Patient and Device resources so they are not re-uploaded.
  •  Example of a numeric. This example is a simple numeric observation of a pulse rate from a pulse oximeter. This particular example also has a component as the original measurement has a Supplemental Types attribute indicating that this is a SPOT measurement (a stable average).
  •  Example of an Rtsa. This example is an RTSA observation of a pleth signal from a pulse oximeter. This very short waveform maps to a valueSampledData element.
  •  Example of a NaN case This example contains a NaN (not a number) measurement.
  •  Example of coded enumeration This example contains measurement that is itself a code. The measurement comes from a Glucose meter and indicates that the glucose measurement was taken after lunch or dinner. It is also known as the meal context.
  •  Example of a ASN1 BITs measurement This example is a device and sensor status measurement from a pulse oximeter. This measurement indicates one or more issues the sensor had attempting to take the measurement, for example, finger poorly positioned, cannot get a sufficiently strong signal, etc.
  •  Example of Compound measurement This example is from a Blood Pressure cuff.
  •  Example of String measurement This example is some arbitrary text from a Glucose meter explaining the failure of the measurement.
  •  Example of a Coincident Time Stamp This example is a Coincident Time stamp where the PHG is better synchronized to NTP time than the PHD. This situation is the most prevalent.
  •  Example of a Coincident Time Stamp with a Time Fault This example is a Coincident Time stamp where the PHD has a time fault; it's current time line is unknown and it reported time stamps in its measurements.
  •  Example of a Blood Pressure PHD This example maps the MDS data from a Blood Pressure PHD. This device did not report Reg-Cert-Data-List information.
  •  Example of a Glucose Monitor PHD This example maps an Glucose monitor PHD. It is referenced by a coded Glucose meal context observation
  •  Example of a Coincident Time Stamp This Coincident Time Stamp observation is referenced by the Blood Pressure Observation
  •  Example of a Coincident Time Stamp referenced by the Glucose Meal Context Observation This Coincident Time Stamp observation is referenced by the the Glucose meal context Observation
  •  Example of a Gateway This example maps an Android Gateway
  •  Example of a Patient This example maps a patient where an optional patient name is included
