PrescribeIT® Specification and Guide Version 5.0

 

Definitions for the profile-medicationorder-original Profile.

1. MedicationOrder
Definition

An order for both supply of the medication and the instructions for administration of the medication to a patient. The resource is called "MedicationOrder" rather than "MedicationPrescription" to generalize the use across inpatient and outpatient settings as well as for care plans, etc.

2. MedicationOrder.id
Definition

The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.

Control1..1
Typeid
Must Supporttrue
Comments

Usage Note: This will usually be a GUID and is assigned by the sending application.

Max Length0
3. MedicationOrder.meta
Definition

The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content may not always be associated with version changes to the resource.

Control0..1
TypeMeta
Max Length0
4. MedicationOrder.implicitRules
Definition

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content.

Control0..1
Typeuri
Is Modifiertrue
Comments

Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element as much as possible.

Max Length0
5. MedicationOrder.language
Definition

The base language in which the resource is written.

Control0..1
BindingThe codes SHALL be taken from http://tools.ietf.org/html/bcp47 A human language.

Typecode
Comments

Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).

Max Length0
6. MedicationOrder.text
Definition

A human-readable narrative that contains a summary of the resource, and may be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.

Control0..1 This element is affected by the following invariants: dom-1
TypeNarrative
Alternate Namesnarrative, html, xhtml, display
Comments

Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative.

Max Length0
7. MedicationOrder.contained
Definition

These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope.

Control0..*
TypeResource
Alternate Namesinline resources, anonymous resources, contained resources
Comments

This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again.

Definition

Allows pharmacies to indicate that the original prescription (for which adapted medication order is based on) has been inactivated in the DIS.

Control0..1
TypeExtension(Medication Order - Stop Notified) (Extension Type: boolean)
Must Supporttrue
Comments

Conformance Rule: Pharmacies are to set this flag to True when they are responsible for inactivating the original medication order on the DIS which the adapted prescription is replacing. If the pharmacy is not inactivating the original medication order on the DIS set this flag to false. This only applies in provinces where jurisdictional DIS exists and when the DIS of the Original Prescription exists. In provinces where a DIS does not exist this element can be omitted or set to false.

10. MedicationOrder.modifierExtension
Definition

May be used to represent additional information that is not part of the basic definition of the resource, and that modifies the understanding of the element that contains it. Usually modifier elements provide negation or qualification. In order to make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.

Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "/[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server.

TypeChoice of: Range, Quantity(SimpleQuantity)
[x] NoteSee Choice of Data Types for further information about how to use [x]
Comments

Note that this specifies the quantity of the specified medication, not the quantity for each active ingredient(s). Each ingredient amount can be communicated in the Medication resource. For example, if one wants to communicate that a tablet was 375 mg, where the dose was one tablet, you can use the Medication resource to document that the tablet was comprised of 375 mg of drug XYZ. Alternatively if the dose was 375 mg, then you may only need to use the Medication resource to indicate this was a tablet. If the example were an IV such as dopamine and you wanted to communicate that 400mg of dopamine was mixed in 500 ml of some IV solution, then this would all be communicated in the Medication resource. If the administration is not intended to be instantaneous (rate is present or timing has a duration), this can be specified to convey the total amount to be administered over the period of time as indicated by the schedule e.g. 500 ml in dose, with timing used to convey that this should be done over 4 hours.

68. MedicationOrder.dosageInstruction.rate[x]
Definition

Identifies the speed with which the medication was or will be introduced into the patient. Typically the rate for an infusion e.g. 100 ml per 1 hour or 100 ml/hr. May also be expressed as a rate per unit of time e.g. 500 ml per 2 hours. Currently we do not specify a default of '1' in the denominator, but this is being discussed. Other examples: 200 mcg/min or 200 mcg/1 minute; 1 liter/8 hours.

Comments

It is possible to supply both a rate and a doseQuantity to provide full details about how the medication is to be administered and supplied. If the rate is intended to change over time, depending on local rules/regulations, each change should be captured as a new version of the MedicationOrder with an updated rate, or captured with a new MedicationOrder with the new rate.

This indicates the validity period of a prescription (stale dating the Prescription).

Control0..1
TypePeriod
Requirements

Indicates when the Prescription becomes valid, and when it ceases to be a dispensable Prescription.

Comments

It reflects the prescriber perspective for the validity of the prescription. Dispenses must not be made against the prescription outside of this period. The lower-bound of the Dispensing Window signifies the earliest date that the prescription can be filled for the first time. If an upper-bound is not specified then the Prescription is open-ended or will default to a stale-date based on regulations.

76. MedicationOrder.dispenseRequest.numberOfRepeatsAllowed
Definition

An integer indicating the number of additional times (aka refills or repeats) the patient can receive the prescribed medication. Usage Notes: This integer does NOT include the original order dispense. This means that if an order indicates dispense 30 tablets plus "3 repeats", then the order can be dispensed a total of 4 times and the patient can receive a total of 120 tablets.

TypeQuantity(Duration)
Comments

In some situations, this attribute may be used instead of quantity to identify the amount supplied by how long it is expected to last, rather than the physical quantity issued, e.g. 90 days supply of medication (based on an ordered dosage) When possible, it is always better to specify quantity, as this tends to be more precise. expectedSupplyDuration will always be an estimate that can be influenced by external factors.
