All codes in this table are from the system

  overall-studyOverall studyUsed for documenting the start and end of the overall study, distinct from progress states.
  activeActiveStudy is opened for accrual.
  active-but-not-recruitingActive, not recruitingThe study is ongoing, and participants are receiving an intervention or being examined, but potential participants are not currently being recruited or enrolled.
  administratively-completedAdministratively CompletedStudy is completed prematurely and will not resume; patients are no longer examined nor treated.
  approvedApprovedProtocol is approved by the review board.
  closed-to-accrualClosed to AccrualStudy is closed for accrual; patients can be examined and treated.
  closed-to-accrual-and-interventionClosed to Accrual and InterventionStudy is closed to accrual and intervention, i.e. the study is closed to enrollment, all study subjects have completed treatment or intervention but are still being followed according to the primary objective of the study.
  completedCompletedThe study closed according to the study plan. There will be no further treatments, interventions or data collection.
  disapprovedDisapprovedProtocol was disapproved by the review board.
  enrolling-by-invitationEnrolling by invitationThe study is selecting its participants from a population, or group of people, decided on by the researchers in advance. These studies are not open to everyone who meets the eligibility criteria but only to people in that particular population, who are specifically invited to participate.
  in-reviewIn ReviewProtocol is submitted to the review board for approval.
  not-yet-recruitingNot yet recruitingThe study has not started recruiting participants.
  recruitingRecruitingThe study is currently recruiting participants.
  temporarily-closed-to-accrualTemporarily Closed to AccrualStudy is temporarily closed for accrual; can be potentially resumed in the future; patients can be examined and treated.
  temporarily-closed-to-accrual-and-interventionTemporarily Closed to Accrual and InterventionStudy is temporarily closed for accrual and intervention and potentially can be resumed in the future.
  terminatedTerminatedThe study has stopped early and will not start again. Participants are no longer being examined or treated.
  withdrawnWithdrawnProtocol was withdrawn by the lead organization.

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
