A Diagnostic report - a combination of request information, atomic results, images, interpretation, as well as formatted reportsThe findings and interpretation of diagnostic tests performed on patients, groups of patients, devices, and locations, and/or specimens derived from these. The report includes clinical context such as requesting and provider information, and some mix of atomic results, images, textual and coded interpretations, and formatted representation of diagnostic reports.This is intended to capture a single report, and is not suitable for use in displaying summary information that covers multiple reports. For example, this resource has not been designed for laboratory cumulative reporting formats nor detailed structured reports for sequencing.
identifierBusiness identifier for reportIdentifiers assigned to this report by the performer or other systems.Usually assigned by the Information System of the diagnostic service provider (filler id).
basedOnWhat was requestedDetails concerning a service requested.Note: Usually there is one test request for each result, however in some circumstances multiple test requests may be represented using a single test result resource. Note that there are also cases where one request leads to multiple reports.

categoryService categoryA code that classifies the clinical discipline, department or diagnostic service that created the report (e.g. cardiology, biochemistry, hematology, MRI). This is used for searching, sorting and display purposes.Multiple categories are allowed using various categorization schemes. The level of granularity is defined by the category concepts in the value set. More fine-grained filtering can be performed using the metadata and/or terminology hierarchy in DiagnosticReport.code.

encounterHealth care event when test orderedThe healthcare event (e.g. a patient and healthcare provider interaction) which this DiagnosticReport is about.This will typically be the encounter the event occurred within, but some events may be initiated prior to or after the official completion of an encounter but still be tied to the context of the encounter (e.g. pre-admission laboratory tests).
effective[x]Clinically relevant time/time-period for reportThe time or time-period the observed values are related to. When the subject of the report is a patient, this is usually either the time of the procedure or of specimen collection(s), but very often the source of the date/time is not known, only the date/time itself.If the diagnostic procedure was performed on the patient, this is the time it was performed. If there are specimens, the diagnostically relevant time can be derived from the specimen collection times, but the specimen information is not always available, and the exact relationship between the specimens and the diagnostically relevant time is not always automatic.

Scope and Usage

This resource is an event resource from a FHIR workflow perspective - see Workflow. It is the intent of the Orders and Observation Workgroup to align this resource with the workflow pattern for event resources.

A diagnostic report is the set of information that is typically provided by a diagnostic service when investigations are complete. The information includes a mix of atomic results, text reports, images, and codes. The mix varies depending on the nature of the diagnostic procedure, and sometimes on the nature of the outcomes for a particular investigation. In FHIR, the report can be conveyed in a variety of ways including a Document, RESTful API, or Messaging framework. Included within each of these, would be the DiagnosticReport resource itself.

The DiagnosticReport resource has information about the diagnostic report itself, and about the subject and, in the case of laboratory tests, the specimen of the report. It can also refer to the request details and atomic observations details or image instances. Report conclusions can be expressed as a simple text blob, structured coded data or as an attached fully formatted report such as a PDF.

The DiagnosticReport resource is suitable for the following kinds of diagnostic reports:

The DiagnosticReport resource is not intended to support cumulative result presentation (tabular presentation of past and present results in the resource). The DiagnosticReport resource does not yet provide full support for detailed structured reports of sequencing; this is planned for a future release.

Background and Context

Diagnostic Report Names

The words "tests", "results", "observations", "panels" and "batteries" are often used interchangeably when describing the various parts of a diagnostic report. This leads to much confusion. The naming confusion is worsened because of the wide variety of forms that the result of a diagnostic investigation can take, as described above. Languages other than English have their own variations on this theme.

This resource uses one particular set of terms. A practitioner "requests" a set of "tests". The diagnostic service returns a "report" which may contain a "narrative" - a written summary of the outcomes, and/or "results" - the individual pieces of atomic data which each are "observations". The results are assembled in "groups" which are nested structures of Observations (traditionally referred to as "panels" or " batteries" by laboratories) that can be used to represent relationships between the individual data items.

Boundaries and Relationships

Note that many diagnostic processes are procedures that generate observations and diagnostic reports. In many cases, such an observation does not require an explicit representation of the procedure used to create the observation, but where there are details of interest about how the diagnostic procedure was performed, the Procedure resource is used to describe the activity.

In contrast to the Observation resource, the DiagnosticReport resource typically includes additional clinical context and some mix of atomic results, images, imaging reports, textual and coded interpretation, and formatted representations. Laboratory reports, pathology reports, and imaging reports should be represented using the DiagnosticReport resource. The Observation resource is referenced by the DiagnosticReport to provide the atomic results for a particular investigation.

If you have a highly structured report, then use DiagnosticReport - it has data and workflow support. Details about the request for a diagnostic investigation are captured in the various "request" resources (e.g., the ServiceRequest) and allow the report to connect to clinical workflows. For more narrative driven reports with less work flow (histology/mortuary, etc.), the Composition resource would be more appropriate.

Image and media representations of the report and supporting images are referenced in the DiagnosticReport resource. The details and actual image instances can be referenced directly in Diagnostic report using the "imaging" element or by indirect reference through the ImagingStudy resources which represent the content produced in a DICOM imaging study or set of DICOM Instances for a patient.

Notes:

Identifiers

The identifier datatype has a type element that may be used to distinguish the identifiers assigned by the requester and the performer of the request (known as the 'Placer' and 'Filler' in the HL7 Version 2 Messaging Standard). Use the identifier type code "PLAC" for the Placer Identifier and "FILL" for the Filler identifier as is shown in the example below:

<!-- Placer identifier-->
<identifier>
<type>
<coding>
  <system value="http://terminology.hl7.org/CodeSystem/v2-0203"/>
  <code value="PLAC"/>
</coding>
<text value="Placer"/>
</type>
<system value="urn:oid:1.3.4.5.6.7"/>
<value value="2345234234234"/>
</identifier>
<!-- Filler identifier-->
<identifier>
<type>
<coding>
  <system value="http://terminology.hl7.org/CodeSystem/v2-0203"/>

</coding>
<text value="Placer"/>
</type>
<system value=" http://terminology.hl7.org/CodeSystem/v2-0203"/>
<value value="567890"/>
</identifier>

Clinically Relevant Time

If the diagnostic procedure was performed on the patient directly, the effective[x] element is a dateTime, the time it was performed. If specimens were taken, the clinically relevant time of the report can be derived from the specimen collection times, but since detailed specimen information is not always available, and nor is the clinically relevant time always exactly the specimen collection time (e.g. complex timed tests), the reports SHALL always include a effective[x] element. Note that HL7 v2 messages often carry a diagnostically relevant time without carrying any specimen information.

Associated Observations

Associated Images

ImagingStudy and ImageObjectStudy and the media element are somewhat overlapping - typically, the list of image references in the image element will also be found in one of the imaging study resources. However each caters to different types of displays for different types of purposes. Neither, either, or both may be provided.

Diagnostic Report Status

Report Content

Typically, a report is either: all data, no narrative (e.g. Core lab) or a mix of data with some concluding narrative (e.g. Structured Pathology Report, Bone Density), or all narrative (for example a typical imaging report, histopathology). This resource provides for these 3 different presentations:

Note that the conclusion and the coded diagnoses are part of the atomic data, and SHOULD be duplicated in the narrative and in the presented form if the latter is present. The narrative and the presented form serve the same function: a representation of the report for a human. The presented form is included since diagnostic service reports often contain presentation features that are not easy to reproduce in the HTML narrative. Whether or not the presented form is included, the narrative must be a clinically safe view of the diagnostic report; at a minimum, this could be fulfilled by a note indicating that the narrative is not proper representation of the report, and that the presented form must be used, or a generated view from the atomic data. However consumers of the report will best be served if the narrative contains clinically relevant data from the form. Commonly, the following patterns are used:

Note that the nature of reports from the various disciplines that provide diagnostic reports are changing quickly, as expert systems provide improved narrative reporting in high volume reports, structured reporting brings additional data to areas that have classically been narrative based, and the nature of the imaging and laboratory procedures are merging. As a consequence the patterns described above are only examples of how a diagnostic report can be used.

Genetic Observations

Genetic reporting makes heavy use of the DiagnosticReport and Observation resources. An implementation guide describing how to represent genetic results can be found here.
