An identified person that can be considered for inclusion in a study.


A person that has met the eligibility criteria for inclusion in a study.


A person is no longer receiving study intervention and/or being evaluated with tests and procedures according to the protocol, but they are being monitored on a protocol-prescribed schedule.


A person who did not meet one or more criteria required for participation in a study is considered to have failed screening or is ineligible for the study.

  not-registeredhttp://terminology.hl7.org/CodeSystem/research-subject-stateNot Registered

A person for whom registration was not completed.


A person that has ended their participation on a study either because their treatment/observation is complete or through not responding, withdrawal, non-compliance and/or adverse event.


A person that is enrolled or registered on a study.


The person is receiving the treatment or participating in an activity (e.g. yoga, diet, etc.) that the study is evaluating.


The subject is being evaluated via tests and assessments according to the study calendar, but is not receiving any intervention. Note that this state is study-dependent and might not exist in all studies. A synonym for this is "short-term follow-up".

  pending-on-studyhttp://terminology.hl7.org/CodeSystem/research-subject-statePending on-study

A person is pre-registered for a study.

  potential-candidatehttp://terminology.hl7.org/CodeSystem/research-subject-statePotential Candidate

A person that is potentially eligible for participation in the study.


A person who is being evaluated for eligibility for a study.


The person has withdrawn their participation in the study before registration.

Explanation of the columns that may appear on this page:

LvlA few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
