RLMedicationRequestOssigenoterapia

Identifiers associated with this medication request that are defined by business processes and/or used to refer to it when a direct URL reference to the resource itself is not appropriate. They are business identifiers assigned to this resource by the performer or other systems and remain constant as the resource is updated and propagates from server to server.

This is a business identifier, not a resource identifier.

Captures the reason for the current state of the MedicationRequest.

This is generally only used for "exception" statuses such as "suspended" or "cancelled". The reason why the MedicationRequest was created at all is captured in reasonCode, not here.

Identifies the reasons for a given status.

Indicates the type of medication request (for example, where the medication is expected to be consumed or administered (i.e. inpatient or outpatient)).

The category can be used to include where the medication is expected to be consumed or other types of requests.

A coded concept identifying the category of medication request. For example, where the medication is to be consumed or administered, or the type of medication treatment.

Indicates how quickly the Medication Request should be addressed with respect to other requests.

Note that FHIR strings SHALL NOT exceed 1MB in size

Identifies the level of importance to be assigned to actioning the request.

If true indicates that the provider is asking for the medication request not to occur.

If do not perform is not specified, the request is a positive request e.g. "do perform".

The version of the code system which was used when choosing this code. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.

Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

Indicates that this coding was chosen by a user directly - e.g. off a pick list of available items (codes or displays).

This has been identified as a clinical safety criterium - that this exact system/code pair was chosen explicitly, rather than inferred by the system based on some rules or language processing.

Amongst a set of alternatives, a directly chosen code is the most appropriate starting point for new translations. There is some ambiguity about what exactly 'directly chosen' implies, and trading partner agreement may be needed to clarify the use of this element and its consequences more completely.

A human language representation of the concept as seen/selected/uttered by the user who entered the data and/or which represents the intended meaning of the user.

The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source.

Very often the text is the same as a displayName of one of the codings.

The Encounter during which this [x] was created or to which the creation of this record is tightly associated.

This will typically be the encounter the event occurred within, but some activities may be initiated prior to or after the official completion of an encounter but still be tied to the context of the encounter." If there is a need to link to episodes of care they will be handled with an extension.

Include additional information (for example, patient height and weight) that supports the ordering of the medication.

References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.

Indicates the type of performer of the administration of the medication.

If specified without indicating a performer, this indicates that the performer must be of the specified type. If specified with a performer then it indicates the requirements of the performer if the designated performer is not available.

Identifies the type of individual that is desired to administer the medication.

The person who entered the order on behalf of another individual for example in the case of a verbal or a telephone order.

The reason or the indication for ordering or not ordering the medication.

This could be a diagnosis code. If a full condition record exists or additional detail is needed, use reasonReference.

A coded concept indicating why the medication was ordered.

Condition or observation that supports why the medication was ordered.

This is a reference to a condition or observation that is the reason for the medication order. If only a code exists, use reasonCode.

The URL pointing to a protocol, guideline, orderset, or other definition that is adhered to in whole or in part by this MedicationRequest.

see Canonical References

see http://en.wikipedia.org/wiki/Uniform_resource_identifier

A shared identifier common to all requests that were authorized more or less simultaneously by a single author, representing the identifier of the requisition or prescription.

Requests are linked either by a "basedOn" relationship (i.e. one request is fulfilling another) or by having a common requisition. Requests that are part of the same requisition are generally treated independently from the perspective of changing their state or maintaining them after initial creation.

The description of the overall patte3rn of the administration of the medication to the patient.

This attribute should not be confused with the protocol of the medication.

Identifies the overall pattern of medication administratio.

Insurance plans, coverage extensions, pre-authorizations and/or pre-determinations that may be required for delivering the requested service.

References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.

Indicates the order in which the dosage instructions should be applied or interpreted.

If the sequence number of multiple Dosages is the same, then it is implied that the instructions are to be treated as concurrent. If the sequence number is different, then the Dosages are intended to be sequential.

32 bit number; for values larger than this, use decimal

Free text dosage instructions e.g. SIG.

Free text dosage instructions can be used for cases where the instructions are too complex to code. The content of this attribute does not include the name or description of the medication. When coded instructions are present, the free text instructions may still be present for display to humans taking or administering the medication. It is expected that the text instructions will always be populated. If the dosage.timing attribute is also populated, then the dosage.text should reflect the same information as the timing. Additional information about administration or preparation of the medication should be included as text.

Note that FHIR strings SHALL NOT exceed 1MB in size

Supplemental instructions to the patient on how to take the medication (e.g. "with meals" or"take half to one hour before food") or warnings for the patient about the medication (e.g. "may cause drowsiness" or "avoid exposure of skin to direct sunlight or sunlamps").

Additional instruction is intended to be coded, but where no code exists, the element could include text. For example, "Swallow with plenty of water" which might or might not be coded.

Information about administration or preparation of the medication (e.g. "infuse as rapidly as possibly via intraperitoneal port" or "immediately following drug x") should be populated in dosage.text.

A coded concept identifying additional instructions such as "take with water" or "avoid operating heavy machinery".

Instructions in terms that are understood by the patient or consumer.

Note that FHIR strings SHALL NOT exceed 1MB in size

Identifies specific times when the event occurs.

In a Medication Administration Record, for instance, you need to take a general specification, and turn it into a precise specification.

A total count of the desired number of repetitions across the duration of the entire timing specification. If countMax is present, this element indicates the lower bound of the allowed range of count values.

Repetitions may be limited by end time or total occurrences.

If you have both bounds and count, then this should be understood as within the bounds period, until count times happens.

If present, indicates that the count is a range - so to perform the action between [count] and [countMax] times.

32 bit number; for values larger than this, use decimal

If present, indicates that the duration is a range - so to perform the action between [duration] and [durationMax] time length.

Some activities are not instantaneous and need to be maintained for a period of time.

For some events the duration is part of the definition of the event (e.g. IV infusions, where the duration is implicit in the specified quantity and rate). For others, it's part of the timing specification (e.g. exercise).

The number of times to repeat the action within the specified period. If frequencyMax is present, this element indicates the lower bound of the allowed range of the frequency.

32 bit number; for values larger than this, use decimal

If no frequency is stated, the assumption is that the event occurs once per period, but systems SHOULD always be specific about this

If present, indicates that the frequency is a range - so to repeat between [frequency] and [frequencyMax] times within the period or period range.

32 bit number; for values larger than this, use decimal

Indicates the duration of time over which repetitions are to occur; e.g. to express "3 times per day", 3 would be the frequency and "1 day" would be the period. If periodMax is present, this element indicates the lower bound of the allowed range of the period length.

Do not use an IEEE type floating point type, instead use something that works like a true decimal, with inbuilt precision (e.g. Java BigInteger)

If present, indicates that the period is a range from [period] to [periodMax], allowing expressing concepts such as "do this once every 3-5 days.

Do not use an IEEE type floating point type, instead use something that works like a true decimal, with inbuilt precision (e.g. Java BigInteger)

The units of time for the period in UCUM units.

Note that FHIR strings SHALL NOT exceed 1MB in size

A unit of time (units from UCUM).

If one or more days of week is provided, then the action happens only on the specified day(s).

If no days are specified, the action is assumed to happen every day as otherwise specified. The elements frequency and period cannot be used as well as dayOfWeek.

Specified time of day for action to take place.

When time of day is specified, it is inferred that the action happens every day (as filtered by dayofWeek) on the specified times. The elements when, frequency and period cannot be used as well as timeOfDay.

An approximate time period during the day, potentially linked to an event of daily living that indicates when the action should occur.

Timings are frequently determined by occurrences such as waking, eating and sleep.

When more than one event is listed, the event is tied to the union of the specified events.

Real world event relating to the schedule.

The number of minutes from the event. If the event code does not indicate whether the minutes is before or after the event, then the offset is assumed to be after the event.

32 bit number; for values larger than this, use decimal

A code for the timing schedule (or just text in code.text). Some codes such as BID are ubiquitous, but many institutions define their own additional codes. If a code is provided, the code is understood to be a complete statement of whatever is specified in the structured timing data, and either the code or the data may be used to interpret the Timing, with the exception that .repeat.bounds still applies over the code (and is not contained in the code).

BID etc. are defined as 'at institutionally specified times'. For example, an institution may choose that BID is "always at 7am and 6pm". If it is inappropriate for this choice to be made, the code BID should not be used. Instead, a distinct organization-specific code should be used in place of the HL7-defined BID code and/or a structured representation should be used (in this case, specifying the two event times).

Code for a known / defined timing pattern.

Body site to administer to.

A coded specification of the anatomic site where the medication first enters the body.

If the use case requires attributes from the BodySite resource (e.g. to identify and track separately) then use the standard extension bodySite. May be a summary code, or a reference to a very precise definition of the location, or both.

A coded concept describing the site location the medicine enters into or onto the body.

How drug should enter body.

A code specifying the route or physiological path of administration of a therapeutic agent into or onto a patient's body.

Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination.

A coded concept describing the route or physiological path of administration of a therapeutic agent into or onto the body of a subject.

Technique for administering medication.

A coded value indicating the method by which the medication is introduced into or onto the body. Most commonly used for injections. For examples, Slow Push; Deep IV.

Terminologies used often pre-coordinate this term with the route and or form of administration.

A coded concept describing the technique by which the medicine is administered.

The kind of dose or rate specified, for example, ordered or calculated.

If the type is not populated, assume to be "ordered".

Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination.

The kind of dose or rate specified.

The identification of the system that provides the coded form of the unit.

Need to know the system that defines the coded form of the unit.

see http://en.wikipedia.org/wiki/Uniform_resource_identifier

A computer processable form of the unit in some unit representation system.

Need a computable form of the unit that is fixed across all forms. UCUM provides this for quantities, but SNOMED CT provides many units of interest.

The preferred system is UCUM, but SNOMED CT can also be used (for customary units) or ISO 4217 for currency. The context of use may additionally require a code from a particular system.

Upper limit on medication per unit of time.

The maximum total quantity of a therapeutic substance that may be administered to a subject over the period of time. For example, 1000mg in 24 hours.

This is intended for use as an adjunct to the dosage when there is an upper cap. For example "2 tablets every 4 hours to a maximum of 8/day".

Upper limit on medication per administration.

The maximum total quantity of a therapeutic substance that may be administered to a subject per administration.

This is intended for use as an adjunct to the dosage when there is an upper cap. For example, a body surface area related dose with a maximum amount, such as 1.5 mg/m2 (maximum 2 mg) IV over 5 – 10 minutes would have doseQuantity of 1.5 mg/m2 and maxDosePerAdministration of 2 mg.

Upper limit on medication per lifetime of the patient.

The maximum total quantity of a therapeutic substance that may be administered per lifetime of the subject.

The context of use may frequently define what kind of quantity this is and therefore what kind of units can be used. The context of use may also restrict the values for the comparator.

The amount or quantity to provide as part of the first dispense.

The context of use may frequently define what kind of quantity this is and therefore what kind of units can be used. The context of use may also restrict the values for the comparator.
