Detailed Descriptions for the elements in the ResearchSubject resource.

ResearchSubject
Element Id	ResearchSubject
Definition	A ResearchSubject is a participant or object which is the recipient of investigative activities in a research study.
Short Display	Participant or object which is the recipient of investigative activities in a study
Cardinality	0..*
Type	DomainResource
Alternate Names	Study Subject
Summary	false
Comments	Need to make sure we encompass public health studies.
ResearchSubject.identifier
Element Id	ResearchSubject.identifier
Definition	Identifiers assigned to this research subject for a study.
Short Display	Business Identifier for research subject in a study
Note	This is a business identifier, not a resource identifier (see discussion)
Cardinality	0..*
Type	Identifier
Summary	true
ResearchSubject.status
Element Id	ResearchSubject.status
Definition	The publication state of the resource (not of the subject).
Short Display	draft \| active \| retired \| unknown
Cardinality	1..1
Terminology Binding	PublicationStatus (Required)
Type	code
Is Modifier	true (Reason: This element is labeled as a modifier because it is a status element that contains status entered-in-error which means that the resource should not be treated as valid)
Summary	true
ResearchSubject.progress
Element Id	ResearchSubject.progress
Definition	The current state (status) of the subject and resons for status change where appropriate.
Short Display	Subject status
Cardinality	0..*
Summary	false
Comments	This is intended to deal with the confusion routinely created by haing two conflated concepts of being in a particular state and having achieved a particular milestone. In strict terms a milestone is a point of time event that results in a change from one state to another. The state before the milestone is achieved is often given the same name as the milestone, and sometimes the state may have the same description. For instance "Randomised" and "Visit 1" may be different milestones but the state remains at "on study" after each of them. It is likely that more than one "state" pattern will be recorded for a subject and a type has been introduced to allow this simultaneous recording.
ResearchSubject.progress.type
Element Id	ResearchSubject.progress.type
Definition	Identifies the aspect of the subject's journey that the state refers to.
Short Display	state \| milestone
Cardinality	0..1
Terminology Binding	Research Subject State Type (Example)
Type	CodeableConcept
Summary	false
ResearchSubject.progress.subjectState
Element Id	ResearchSubject.progress.subjectState
Definition	The current state of the subject.
Short Display	candidate \| eligible \| follow-up \| ineligible \| not-registered \| off-study \| on-study \| on-study-intervention \| on-study-observation \| pending-on-study \| potential-candidate \| screening \| withdrawn
Cardinality	0..1
Terminology Binding	Research Subject State (Required)
Type	CodeableConcept
Summary	false
ResearchSubject.progress.milestone

Definition	The milestones the subject has passed through.
Short Display	SignedUp \| Screened \| Randomized
Cardinality	0..1
Terminology Binding	Research Subject Milestone (Example)
Type	CodeableConcept
Summary	false
Comments	There can be multiple entries but it is also valid to just have the most recent. This should npt be rlied upon as the full path the subject has taken.
ResearchSubject.progress.reason
Element Id	ResearchSubject.progress.reason
Definition	The reason for the state change. If coded it should follow the formal subject state model.
Short Display	State change reason

ResearchSubject.progress.startDate
Element Id	ResearchSubject.progress.startDate
Definition	The date when the new status started.
Short Display	State change date
Cardinality	0..1
Type	dateTime
Requirements	This was originally defined as the date when the change in status occurred. This assumed all states were recorded which is not true. Hence the need to track the end of the state.
