Expansion based on AdverseEventCausalityAssessment v0.1.0 (CodeSystem)

All codes from system http://terminology.hl7.org/CodeSystem/adverse-event-causality-assess

certainCertaini) Event or laboratory test abnormality, with plausible time relationship to drug intake; ii) Cannot be explained by disease or other drugs; iii) Response to withdrawal plausible (pharmacologically, pathologically); iv) Event definitive pharmacologically or phenomenologically (i.e. an objective and specific medical disorder or a recognized pharmacological phenomenon); or v) Re-challenge satisfactory, if necessary.
probably-likelyProbably/Likelyi) Event or laboratory test abnormality, with reasonable time relationship to drug intake; ii) Unlikely to be attributed to disease or other drugs; iii) Response to withdrawal clinically reasonable; or iv) Re-challenge not required.
possiblePossiblei) Event or laboratory test abnormality, with reasonable time relationship to drug intake; ii) Could also be explained by disease or other drugs; or iii) Information on drug withdrawal may be lacking or unclear.
unlikelyUnlikelyi) Event or laboratory test abnormality, with a time to drug intake that makes a relationship improbable (but not impossible); or ii) Disease or other drugs provide plausible explanations.

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The 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
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
