12.14 Resource ServiceRequest - Content

Orders and Observations Work Group Maturity Level : 2   Trial Use Compartments : Device , Encounter , Patient , Practitioner , RelatedPerson

A record of a request for service such as diagnostic investigations, treatments, or operations to be performed.

12.14.1 Scope and Usage

STU Trial-Use Note: In terms of scope and usage, the Patient Care and Orders and Observations workgroups wish to draw the attention of reviewers and implementers to the following issues:

  1. ReferralRequest and ProcedureRequest have been merged into ServiceRequest since their content was nearly identical and no clear distinction was identified for managing the transfer of care responsibility from one practitioner/organization to another (Note that for STU3 DiagnosticRequest and ProcedureRequest were merged). We are seeking input on:
    • How to represent whether a transfer of care is being requested
    • Which elements if any in the ServiceRequest resource might not be applicable for a referral.
  2. The following elements have been added to this resource:
  3. Based on the workflow request pattern changes, the following have been updated:
    • The definition element was renamed to instantiates
    • The requester collapsed into a single element ( requester.agent and request.onBehalfOf elements removed) and a reference to PractitionerRole added to the choices of reference targets
    • Additional reference targets added to the performer , and reasonReference elements.
    • Added a statusReason standard extension - We would like implementer input on whether extension should be promoted to an inline element.

This resource is a request resource from a FHIR workflow perspective - see Workflow .

ServiceRequest is a record of a request for a procedure or diagnostic or other service to be planned, proposed, or performed, as distinguished by the ServiceRequest.intent field value, with or on a patient. The procedure will lead to either a Procedure or DiagnosticReport , that in turn may reference one or more Observations , that summarizes the performance of the procedures and associated documentation such as observations, images, findings that are relevant to the treatment/management of the subject. This resource may be used to share relevant information required to support a referral or a transfer of care request from one practitioner or organization to another when a patient is required to be referred to another provider for a consultation /second opinion and/or for short term or longer term management of one or more health issues or problems.

Examples include:

  • diagnostic tests/studies
  • endoscopic procedures
  • counseling
  • biopsies
  • therapies (e.g., physio-, social-, psychological-)
  • (exploratory) surgeries or procedures
  • exercises
  • specialist consultation and assessments
  • community services
  • nursing services
  • pharmacist medication review
  • and other clinical interventions.

Procedures may be performed by a healthcare professional, a friend or relative or in some cases by the patient themselves.

The principal intention of ServiceRequest is to support ordering procedures for one patient (which includes non-human patients in veterinary medicine). However, in many contexts, healthcare related processes include performing diagnostic investigations on groups of subjects, devices involved in the provision of healthcare, and even environmental locations such as ducts, bodies of water, etc. ServiceRequest supports all these usages. The service request may represent an order that is entered by a practitioner in a CPOE system as well as a proposal made by a clinical decision support (CDS) system based on a patient's clinical record and context of care. Planned procedures referenced by a CarePlan may also be represented by this resource.

The general work flow that this resource facilitates is that a clinical system creates a service request. The service request is then accessed by or exchanged with a system, perhaps via intermediaries, that represents an organization (e.g., diagnostic or imaging service, surgical team, physical therapy department) that can perform the procedure. The organization receiving the service request will, after it accepts the request, update the request as the work is performed, and then finally issue a report that references the requests that it fulfilled.

The ServiceRequest resource allows requesting only a single procedure. If a workflow requires requesting multiple procedures simultaneously, this is done using multiple instances of this resource. These instances can be linked in different ways, depending on the needs of the workflow. For guidance, refer to the Request pattern

12.14.2 Boundaries and Relationships

ServiceRequest is a record of a proposal/plan or order for a service to be performed that would result in a Procedure , Observation , DiagnosticReport , ImagingStudy or similar resource. In contrast to ServiceRequest, Task which spans both intent and event and tracks the execution through to completion and is intended for "administrative" actions like requesting and tracking things to be done to a record, or keeping track of a checklist of steps such to be performed as part of a fulfilment process. A ServiceRequest can be higher-level authorization that triggered the creation of Task, or it can be the "request" resource Task is seeking to fulfill.

ServiceRequest and CommunicationRequest are related. A CommunicationRequest is a request to merely disclose information. Whereas a ServiceRequest would be used to request information as part of training or counseling - i.e. when the process will involve verification of the patient's comprehension or an attempt to change the patient's mental state. In some workflows both may exist. For example, upon receiving a CommunicationRequest a practitioner might initiate a ServiceRequest . ServiceRequest.

(Strength=Required) RequestStatus ! » Whether the request is a proposal, plan, an original order or a reflex order (this element modifies the meaning of other elements) intent : code [1..1] « The kind of service request request. (Strength=Required) RequestIntent ! » A code that classifies the service for searching, sorting and display purposes (e.g. "Surgical Procedure") category : CodeableConcept [0..*] « Classification of the requested service. (Strength=Example) Service Request Category ServiceRequestCategoryCodes ?? » Indicates how quickly the ServiceRequest should be addressed with respect to other requests priority : code [0..1] « Identifies the level of importance to be assigned to actioning the request request. (Strength=Required) RequestPriority ! » Set this to true if the record is saying that the service/procedure should NOT be performed (this element modifies the meaning of other elements) doNotPerform : boolean [0..1] A code that identifies a particular service (i.e., procedure, diagnostic investigation, or panel of investigations) that have been requested code : CodeableConcept [0..1] « Codes for tests or services that can be carried out by a designated individual, organization or healthcare service. For laboratory, LOINC is (preferred)[http://build.fhir.org/terminologies.html#preferred] and a valueset using LOINC Order codes is available [here](valueset-diagnostic-requests.html). (Strength=Example) Procedure Codes (SNOMED CT) ProcedureCodes(SNOMEDCT) ?? » Additional details and instructions about the how the services are to be delivered. For example, and order for a urinary catheter may have an order detail for an external or indwelling catheter, or an order for a bandage may require additional instructions specifying how the bandage should be applied orderDetail : CodeableConcept [0..*] « Codified order entry details which are based on order context. (Strength=Example) Service Request Order Details ServiceRequestOrderDetailsCod... ?? » An amount of service being requested which can be a quantity ( for example $1,500 home modification), a ratio ( for example, 20 half day visits per month), or a range (2.0 to 1.8 Gy per fraction) quantity[x] : Type [0..1] « Quantity | Ratio | Range » On whom or what the service is to be performed. This is usually a human patient, but can also be requested on animals, groups of humans or animals, devices such as dialysis machines, or even locations (typically for environmental scans) subject : Reference [1..1] « Patient | Group | Location | Device » An encounter or episode of care that provides additional information about the healthcare context in which this request is made context : Reference [0..1] « Encounter | EpisodeOfCare » The date/time at which the requested service should occur occurrence[x] : Type [0..1] « dateTime | Period | Timing » If a CodeableConcept is present, it indicates the pre-condition for performing the service. For example "pain", "on flare-up", etc asNeeded[x] : Type [0..1] « boolean | CodeableConcept ; A coded concept identifying the pre-condition that should hold prior to performing a procedure. For example "pain", "on flare-up", etc. (Strength=Example) SNOMED CT Medication As Neede...

This is often for billing purposes. May relate to the resources referred to in supportingInformation reasonCode : CodeableConcept [0..*] « Diagnosis or problem codes justifying the reason for requesting the service investigation. (Strength=Example) Procedure Reason ProcedureReasonCodes ?? » Indicates another resource that provides a justification for why this service is being requested.

This information includes diagnosis, clinical findings and other observations. In laboratory ordering these are typically referred to as "ask at order entry questions (AOEs)". This includes observations explicitly requested by the producer (filler) to provide context or supporting information needed to complete the order. For example, reporting the amount of inspired oxygen for blood gas measurements supportingInfo : Reference [0..*] « Any » One or more specimens that the laboratory procedure will use specimen : Reference [0..*] « Specimen » Anatomic location where the procedure should be performed. This is the target site bodySite : CodeableConcept [0..*] « Codes describing anatomical locations. May include laterality.

12.14.3.1 Terminology Bindings

Path Definition Type Reference
ServiceRequest.status The status of a service order. Required RequestStatus
ServiceRequest.intent The kind of service request request. Required RequestIntent
ServiceRequest.category Classification of the requested service. Example Service Request Category Codes ServiceRequestCategoryCodes
ServiceRequest.priority Identifies the level of importance to be assigned to actioning the request request. Required RequestPriority
ServiceRequest.code Codes for tests or services that can be carried out by a designated individual, organization or healthcare service. For laboratory, LOINC is (preferred)[http://build.fhir.org/terminologies.html#preferred] and a valueset using LOINC Order codes is available [here](valueset-diagnostic-requests.html). Example Procedure Codes (SNOMED CT) ProcedureCodes(SNOMEDCT)
ServiceRequest.orderDetail Codified order entry details which are based on order context. Example Service Request Order Details Codes ServiceRequestOrderDetailsCodes
ServiceRequest.asNeeded[x] A coded concept identifying the pre-condition that should hold prior to performing a procedure. For example "pain", "on flare-up", etc. Example SNOMED CT Medication As Needed Reason Codes SNOMEDCTMedicationAsNeededReasonCodes
ServiceRequest.performerType Indicates specific responsibility of an individual within the care team, such as "Primary physician", "Team coordinator", "Caregiver", etc. Example Participant Roles ParticipantRoles
ServiceRequest.locationCode A location type where services are delivered. Example v3.ServiceDeliveryLocationRoleType
ServiceRequest.reasonCode Diagnosis or problem codes justifying the reason for requesting the service investigation. Example Procedure Reason Codes ProcedureReasonCodes
ServiceRequest.bodySite Codes describing anatomical locations. May include laterality. Example SNOMED CT Body Structures SNOMEDCTBodyStructures

12.14.3.2 Constraints

id Level Location Description Expression
prr-1 : Rule (base) orderDetail SHALL only be present if code is present ( expression : orderDetail.empty() or code.exists() )

12.14.4 Notes:

  • Many service requests will create a need to specify a specimen, body site, or body system. The request code will often have this information embedded in it - for example, 'serum glucose' or 'chest x-ray'. Alternatively, the specimen or bodysite element may be used to specify it.
  • The ServiceRequest should only reference the Specimen resource directly when the diagnostic investigation is requested on already existing specimens. Conversely, if the request is entered first with an uncollected specimen, the Specimen resource will reference the ServiceRequest resource when it is created.
  • The reasonCode element is often for billing purposes. It may relate to the resources referred to in supportingInfo element and may be used to decide how a procedure or diagnostic investigation will be performed, or even if it will be performed at all
