**Aliases:** SubjectOfCare Client Resident
**Cardinality:** 0..*
**Mappings:** rim=Patient[classCode=PAT]; interface=ParticipantLiving; cda=ClinicalDocument.recordTarget.patientRole; w5=administrative.individual; dicom=DICOM Tag Mapping
## Patient.identifier
An identifier for this patient
**Definition:** An identifier for this patient.
**Comments:** Systems MAY use identifier for user identities (using the type='USER'). Refer to the [Security and Privacy](administration-module.html#secpriv) section for additional guidance on representing user identities.
**Requirements:** Patients are almost always assigned specific numerical identifiers.
**Cardinality:** 0..*
**Type:** [Identifier](/Identifier)
**Summary:** true
**Mappings:** w5=FiveWs.identifier; v2=PID-3; rim=id; interface=Participant.identifier; cda=.id; dicom=Patient Identifier (0010,0020)
## Patient.active
Whether this patient's record is in active use
**Definition:** Whether this patient record is in active use.
Many systems use this property to mark as non-current patients, such as those that have not been seen for a period of time based on an organization's business rules.
It is often used to filter patient lists to exclude inactive patients
Deceased patients may also be marked as inactive for the same reasons, but may be active for some time after death.
**Comments:** If a record is inactive, and linked to an active record, then future patient/record updates should occur on the other patient.
**Requirements:** Need to be able to mark a patient record as not to be used because it was created in error.
**Meaning if Missing:** This resource is generally assumed to be active if no value is provided for the active element
**Cardinality:** 0..1
**Type:** [boolean](/boolean)
**Summary:** true
**Is Modifier:** true (Reason: This element is labelled as a modifier because it is a status element that can indicate that a record should not be treated as valid)
**Mappings:** w5=FiveWs.status; rim=statusCode; interface=Participant.active; cda=n/a
## Patient.name
A name associated with the patient
**Definition:** A name associated with the individual.
**Comments:** A patient may have multiple names with different uses or applicable periods. For animals, the name is a "HumanName" in the sense that is assigned and used by humans and has the same patterns. Animal names may be communicated as given names, and optionally may include a family name.
**Requirements:** Need to be able to track the patient by multiple names. Examples are your official name and a partner name.

## Patient.telecom
A contact detail for the individual
**Definition:** A contact detail (e.g. a telephone number or an email address) by which the individual may be contacted.
**Comments:** A Patient may have multiple ways to be contacted with different uses or applicable periods. May need to have options for contacting the person urgently and also to help with identification. The address might not go directly to the individual, but may reach another party that is able to proxy for the patient (i.e. home phone, or pet owner's phone).
DO NOT use .telecom properties to represent user identities. Refer to the [Security and Privacy](administration-module.html#secpriv) section for additional guidance on representing user identities.
**Requirements:** People have (primary) ways to contact them in some way such as phone, email.
**Cardinality:** 0..*
**Type:** [ContactPoint](/ContactPoint)
**Summary:** true
**Mappings:** v2=PID-13, PID-14, PID-40; rim=telecom; interface=ParticipantContactable.telecom; cda=.telecom
## Patient.gender
male | female | other | unknown
**Definition:** Administrative Gender - the gender that the patient is considered to have for administration and record keeping purposes.
See the [Patient Gender and Sex section](patient.html#gender) for additional information about communicating patient gender and sex.
**Comments:** The gender might not match the biological sex as determined by genetics or the individual's preferred identification. Note that for both humans and particularly animals, there are other legitimate possibilities than male and female, though the vast majority of systems and contexts only support male and female. Systems providing decision support or enforcing business rules should ideally do this on the basis of Observations dealing with the specific sex or gender aspect of interest (anatomical, chromosomal, social, etc.) However, because these observations are infrequently recorded, defaulting to the administrative gender is common practice. Where such defaulting occurs, rule enforcement should allow for the variation between administrative and biological, chromosomal and other gender aspects. For example, an alert about a hysterectomy on a male should be handled as a warning or overridable error, not a "hard" error.
**Requirements:** Needed for identification of the individual, in combination with (at least) name and birth date.
**Cardinality:** 0..1
**Type:** [code](/code)
**Binding:** required:[administrative-gender](/valueset-administrative-gender)

## Patient.deceased[x]
Indicates if/when the individual is deceased
**Definition:** Indicates the date when the individual died, or, if the date is not known or cannot be estimated, a flag indicating the patient is known to be deceased.
**Comments:** If there's no value in the instance, it means there is no statement on whether or not the individual is deceased. Most systems will interpret the absence of a value as a sign of the person being alive.
**Requirements:** The fact that a patient is deceased influences the clinical process. Also, in human communication and relation management it is necessary to know whether the person is alive.
**Cardinality:** 0..1
**Type:** [boolean](/boolean), [dateTime](/dateTime)
**Summary:** true
**Is Modifier:** true (Reason: This element is labeled as a modifier because once a patient is marked as deceased, the actions that are appropriate to perform on the patient may be significantly different.)

## Patient.multipleBirth[x]
Whether patient is part of a multiple birth
**Definition:** Indicates whether the patient is part of a multiple (boolean) or indicates the actual birth order (integer). This count is relative to the total of live births and fetal losses, which MAY be tracked in the `patient-multipleBirthTotal` extension.
The boolean option for this property can also be used to track that there are known to be multiple fetuses prior to birth.
**Comments:** Where the valueInteger is provided, the number is the birth number in the sequence.
E.g. The middle birth in triplets would be valueInteger=2 and the third born would have valueInteger=3.
If a boolean value was provided for this triplets example, then all 3 patient records would have valueBoolean=true (the ordering is not indicated).
`valueBoolean` can be used to track fetuses. `valueInteger` should only be used after live birth.
**Requirements:** For disambiguation of multiple-birth children, especially relevant where the care provider doesn't meet the patient, such as labs.
**Cardinality:** 0..1

## Patient.communication
A language which may be used to communicate with the patient about his or her health
**Definition:** A language which may be used to communicate with the patient about his or her health.
**Comments:** If no language is specified, this *implies* that the default local language is spoken. If you need to convey proficiency for multiple modes, then you need multiple Patient.Communication associations. For animals, language is not a relevant field, and should be absent from the instance. If the Patient does not speak the default local language, then the Interpreter Required Standard can be used to explicitly declare that an interpreter is required.

For example, "en" for English, or "en-US" for American English versus "en-AU" for Australian English, sgn-US for American Sign Language, sgn-NL for Dutch Sign Language, etc.
Not all systems actually code this but instead have it as free text. Hence CodeableConcept instead of code as the data type.
**Requirements:** Most systems in multilingual countries will want to convey language. Not all systems actually need the regional dialect.
**Cardinality:** 1..1
**Type:** [CodeableConcept](/CodeableConcept)

It is not to be used to record Care Teams, these should be in a CareTeam resource that may be linked to the CarePlan or EpisodeOfCare resources.
Multiple GPs may be recorded against the patient for various reasons, such as a student that has his home GP listed along with the GP at university during the school semesters, or a "fly-in/fly-out" worker that has the onsite GP also included with his home GP to remain aware of medical issues.
Jurisdictions may decide that they can profile this down to 1 if desired, or 1 per type.
