FHIR R4 ServiceRequest Library

Overview

This asset is a component of MuleSoft Accelerator for Healthcare.

MuleSoft Accelerator for Healthcare enables healthcare providers to unlock critical patient data to build a patient 360 within Salesforce Health Cloud, faster and easier than ever before. The solution includes pre-built APIs, connectors, integration templates, and prescriptive end-to-end reference architecture to bring patient demographics information and COVID-19 test results from any EHR into Health Cloud using HL7 V2 or FHIR standards.

The solution also provides a library of United States Core Data for Interoperability (USCDI) and FHIR R4 resources to help healthcare developers adhere to interoperability needs and jumpstart the development of healthcare digital transformation initiatives.

Use case covered

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, which in turn may reference one or more Observations, which summarize 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
