0research-study-prim-purp-typeResearch Study Primary Purpose Type
1  treatmentTreatmentOne or more interventions are being evaluated for treating a disease, syndrome, or condition.
1  preventionPreventionOne or more interventions are being assessed for preventing the development of a specific disease or health condition.
1  diagnosticDiagnosticOne or more interventions are being evaluated for identifying a disease or health condition.
1  supportive-careSupportive CareOne or more interventions are evaluated for maximizing comfort, minimizing side effects, or mitigating against a decline in the participant's health or function.
1  screeningScreeningOne or more interventions are assessed or examined for identifying a condition, or risk factors for a condition, in people who are not yet known to have the condition or risk factor.
1  health-services-researchHealth Services ResearchOne or more interventions for evaluating the delivery, processes, management, organization, or financing of healthcare.
1  basic-scienceBasic ScienceOne or more interventions for examining the basic mechanism of action (for example, physiology or biomechanics of an intervention).
1  device-feasibilityDevice FeasibilityAn intervention of a device product is being evaluated to determine the feasibility of the product or to test a prototype device and not health outcomes. Such studies are conducted to confirm the design and operating specifications of a device before beginning a full clinical trial.
0research-study-phaseResearch Study Phase
1  n-aN/ATrials without phases (for example, studies of devices or behavioral interventions).
1  early-phase-1Early Phase 1Designation for optional exploratory trials conducted in accordance with the United States Food and Drug Administration's (FDA) 2006 Guidance on Exploratory Investigational New Drug (IND) Studies. Formerly called Phase 0.
1  phase-1Phase 1Includes initial studies to determine the metabolism and pharmacologic actions of drugs in humans, the side effects associated with increasing doses, and to gain early evidence of effectiveness; may include healthy participants and/or patients.
1  phase-1-phase-2Phase 1/Phase 2Trials that are a combination of phases 1 and 2.
1  phase-2Phase 2Includes controlled clinical studies conducted to evaluate the effectiveness of the drug for a particular indication or indications in participants with the disease or condition under study and to determine the common short-term side effects and risks.
1  phase-2-phase-3Phase 2/Phase 3Trials that are a combination of phases 2 and 3.
1  phase-3Phase 3Includes trials conducted after preliminary evidence suggesting effectiveness of the drug has been obtained, and are intended to gather additional information to evaluate the overall benefit-risk relationship of the drug.
1  phase-4Phase 4Studies of FDA-approved drugs to delineate additional information including the drug's risks, benefits, and optimal use.

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

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
