Patient Reported Observations

Submitting WG/Project/Implementer Group

Orders and Observations


The HL7 Orders and Observation Work Group is interested in the readiness of the Observation resources to progress to a normative Maturity level. This tract is specifically focused on readiness of Observation to handle Patient reported data - in other words, observations that are reported directly by the patient. In many cases patients are asked to record and report clinical and nutritional data for example using an app on a smart phone. ('gateway'). The goal of this tract is to identify any potential issues and gaps in the Observation resource by stepping through a couple of simple scenarios described below. For example, we discovered that constraining the timing of events to only dateTimes did not account for patient's oftentimes reporting the events as occurring relative to another event - e.g., "before breakfast".

Expected participants


(Todo:Please include information here regarding how much advance preparation will be required if creating a client and/or server.)


Just work with the generic FHIR servers that support the Observation resource and the standard extensions for Observation listed below. These include the FHIR test servers listed here.

Standard extensions for Observation:

  • event-reasonCode reasonCode for Event Pattern HL7 Extensions
  • event-reasonReference reasonReference for Event Pattern HL7 Extensions
  • observation-bodyPosition bodyPosition for Observation HL7 Extensions
  • observation-eventTiming eventTiming for Observation HL7 Extensions
  • observation-focal-subject focal-subject for Observation HL7 Extensions


Clients should provide ability for manually entered patient data. ( i.e. having a patient take and report his/her own pulse , diet, exercise, etc. Alternatively, a patient takes a measurement with a medical device but record the results manually since the device has no direct communication capability )

Scenarios Below are two Sample Scenarios, Participant can elect to choose other Scenarios within the scope of this tract

Sample Scenario 1: Diet

Patient reports what they ate via their Iphone using a nutrition app or some other application ( Details pending ...)

Sample Scenario 2: Home Blood Glucose Monitoring

Patient reports the measurements from there home glucometer via their Iphone using some application supplied by there healthcare provider (Details Pending...)


- Send source of data ( Gataway information, who recorded etc) using the Provenance resource as well: Patient generated data needs good Provenance. And clients that utilize the Observation might want to look to Provenance to understand the source of the data. The server would be required to support Provenance as well.
