9.9 Resource ProcedureRequest - Content

Patient Care Work GroupMaturity Level: 1Compartments: Device, Encounter, Patient, Practitioner, RelatedPerson

A request for a procedure to be performed. May be a proposal or an order.

9.9.1 Scope and Usage

A Procedure Request is a record of a request for a procedure to be performed. It can be used to represent a procedure that is planned, that is proposed, or that is ordered, as distinguished by the value of the ProcedureRequestStatus field.

A procedure is an activity that is performed with or on a patient as part of the provision of care. Examples include surgical procedures, diagnostic procedures, endoscopic procedures, biopsies, counseling, physiotherapy, exercise, etc. Procedures may be performed by a healthcare professional, a friend or relative or in some cases by the patient themselves.

The procedure 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.

9.9.2 Boundaries and Relationships

ProcedureRequest is closely related to other types of "request" resources, particularly DiagnosticRequest and ReferralRequest. In fact, for some services, it may be appropriate to use any one of these resources to request that the procedure be performed. Which one is used may be driven by organization practice and by context. When it is unclear which to use, the following principles may be helpful:

  • ProcedureRequest or DiagnosticRequest are typically used when the requesting clinician has and wishes to exercise the authority (and expertise) to decide exactly what action will be done.
  • A ReferralRequest is used when the requesting practitioner is seeking another practitioner or organization to use their own expertise and/or authority to determine the specific action to take.
  • Whether an activity is deemed to be a procedure or only a diagnostic request is typically driven by how invasive the diagnostic process is. More invasive processes are typically represented as procedures, though the dividing line may vary by organization.

Irrespective of the guidance above, systems should be prepared for some degree of overlap between these resources and be prepared to execute searches against multiple resources in cases where differentiation cannot be guaranteed. As well, in some workflows more than one type of resource or even all three might exist; e.g. Upon receiving a ReferralRequest a practitioner might initiate a DiagnosticRequest. The diagnostic service might then initiate a ProcedureRequest.

The notion of ProcedureRequest and CommunicationRequest are also closely related. The boundary between determining whether an action is considered to be training or counseling (and thus a ProcedureRequest) as opposed to a CommunicationRequest is based on whether there's a specific intent to change the mind-set of the patient. A request to merely disclose information would be considered a CommunicationRequest. Invocation of a process that will involve verification of the patient's comprehension or an attempt to change the patient's mental state would be a ProcedureRequest.

PLANNED CHANGE:

ProcedureRequest is one of the Request resources in the FHIR Workflow specification. As such, it is expected to be adjusted to align with the Request workflow pattern which will involve adding a number of additional data elements and potentially renaming a few elements. Any concerns about performing such alignment are welcome as ballot comments and/or tracker items.
