| − | MedMij specifies the format [http://www.pdfa.org/publication/pdfa-in-a-nutshell-2-0/ PDF/A] for exchanging unstructured documents containing health information. MedMij adopts as much as possible from the Mobile access to Health Documents (MHD) profile from Integrating the Healthcare Enterprise (IHE) that defines a RESTful/HTTP interface to an [http://wiki.ihe.net/index.php/Cross-Enterprise_Document_Sharing XDS] environment using HL7 FHIR STU3 resources. The MHD profile is written to be content agnostic and as such is suitable for much more than PDF/A. For the purposes of this use case we have limited the scope to PDF/A.
| |
| − | | |
| − | MedMij includes the IHE MHD profile as a framework to exchange PDF/A documents. The next section summarizes MHD and contains references to this specification. The following section provides an adaptation of the MHD profile to specify exchange of PDF/A documents in a MedMij context. For example, the MHD actors and transactions are put into perspective of the MedMij actors and systems. The essence of the MHD profile is outlined and example transaction messages have been added.

| − | =IHE MHD specification=
| |
| − | Mobile access to Health Documents (MHD) profile defines a simple HTTP interface to an XDS like environment. It defines four transactions:
| |
| − | # submit submission sets, folders, new documents, and document metadata from the mobile device to a document receiver (Provide Document Bundle),
| |
| − | # find submission sets matching query parameters (Find Document Manifest),
| |
| − | # find document entries containing metadata based on query parameters (Find Document Reference),
| |
| − | # retrieve a copy of a specific document (Retrieve Document).
| |
| − | These transactions leverage the document content and format agnostic metadata concepts from XDS, but simplify them for access by constrained environments such as mobile devices, or other resource constrained systems. The MHD profile does not replace XDS. It can be used to allow mobile devices, or other resource constrained systems, access to an XDS health information exchange.[http://wiki.ihe.net/index.php/Mobile_access_to_Health_Documents_(MHD)]

| − | | |
| − | ===Transactions in scope===
| |
| − | | |
| − | * Find Document Manifests – This transaction is used to issue parameterized queries that result in a list of Document Manifest resources.
| |
| − | * Find Document References – This transaction is used to issue parameterized queries that result in a list of Document Reference resources.
| |
| − | * Retrieve Document – This transaction is used to get documents.
| |
| − | | |
| − | ===Transactions out of scope===
| |
| − | The MHD profile specifies how to send documents from a Document Source to a Document Receiver using the Provide Document Bundle transaction. However sending PDF/A documents is currently out of scope for the MedMij context. The 'Afsprakenstelsel' first focuses on pulling data from a XIS to a PHE before considering push transactions. In the future, specifications of sending PDF/A documents from a PHE will be added.
| |
| − | | |
| − | ==Find and retrieve existing PDF/A document(s)==
| |
| − | | |
| − | ===Find PDF/A or PDF/A collection===
| |
| − | Discovery of PDF/A documents is done with the MHD defined transaction 'Find Document Reference' or 'Find Document Manifest'. The Find Document Reference retrieves FHIR DocumentReference Resources that represents a single reference to document per resource, for example one PDF/A file. The Find Document Manifest retrieves FHIR DocumentManifest Resources. A DocumentManifest Resourse gathers a set of DocumentReference Resources into a single package together with metadata that applies to the collection.
| |
| − | | |
| − | The Document Consumer requests DocumentReference or DocumentManifest Resources, matching a set of criteria, from the Document Responder. The Document Responder returns DocumentReference or DocumentManifest Resources that match the search criteria provided by the Document Consumer.
| |
| − | | |
| − | ====Request message====
| |
| − | '''Search'''
| |
| − | | |
| − | The Document Consumer executes an HTTP GET conform to the FHIR [http://hl7.org/fhir/http.html RESTfull] and [http://hl7.org/fhir/search.html search] specification. A search query would have the following format.
| |
| − |
| |
| − | <pre>
| |
| − | GET [base]DocumentReference?[parameters]{&_format=[mime-type]}
| |
| − | GET [base]DocumentManifest?[parameters]{&_format=[mime-type]}
| |
| − | </pre>
| |
| − | | |
| − | Example query to search for DocumentReferences of type Discharge summary.

| − | <pre>GET http://example.org/fhir/DocumentReference?type=http://loinc.org|18842-5</pre>
| |
| − | | |
| − | '''Search Parameters'''
| |
| − | | |
| − | The Document Consumer may supply, and the Document Responder shall be capable of processing, all query parameters listed below. These search parameters are a selection of the defined search parameters by the HL7 FHIR specification (search parameters: [http://hl7.org/fhir/STU3/documentreference.html#search DocumentReference] , [http://hl7.org/fhir/STU3/documentmanifest.html#search DocumentManifest]).

The Document Responder returns a HTTP Status code appropriate to the processing as well as a Bundle including the matching DocumentReference or DocumentManifest Resources. When the Document Responder needs to report an error or warning, it shall use HTTP error response codes and should include a FHIR [http://hl7.org/fhir/STU3/operationoutcome.html OperationOutcome] with more details on the failure or warning. If the request message is processed successfully, whether or not any DocumentReference or DocumentManifest Resources are found, the HTTP status code shall be 200.
| |

| − | ===Retrieve PDF/A document===
| |
| − | After obtaining the location of the PDF/A document in the DocumentReference.content.attachment.url, the Document Consumer requests the document from the Document Responder. The Document Responder sequentially serves the PDF/A document to the Document Consumer. The context that was established in the initial request shall also apply when retrieving/serving the document contents.
| |
| − | | |
| − | ====Request Message====
| |
| − | This message is an HTTP GET request to retrieve the document. See an example below.
| |
| − | | |
| − | <pre>GET http://example:9556/svc/fhir/Binary/1e404af3-077f-4bee-b7a6-a9be97e1ce32</pre>
| |
| − | | |
| − | The Document Consumer may provide a HTTP Accept header, according to the semantics of the HTTP protocols (see RFC2616, Section 14.1). The only MIME type assured to be returned is the
| |
| − | MIME type indicated in the 'DocumentReference.content.attachment.contentType'. The HTTP If-Unmodified-Since header shall not be included in the GET request
| |
| − | | |
| − | ====Response Message====
| |
| − | The Document Responder shall process the request message. The Document Responder returns a HTTP Status code appropriate to the processing as well as the content of the requested PDF/A document in the HTTP message-body.
| |
| − | | |
| − | The document may be placed inside a FHIR [http://hl7.org/fhir/STU3/binary.html Binary] resource if it is useful to handle pure binary content using the same framework as other resources. Binary resources behave slightly differently to all other resources on the RESTful API. Specifically, when a read request is made for the binary resource that doesn't explicitly specify the FHIR content types "application/fhir+xml" or "application/fhir+json", then the content should be returned using the content type stated in the resource. e.g. if the content type in the resource is "application/pdf", then the content should be returned as a PDF directly.[http://hl7.org/fhir/STU3/binary.html#rest]
| |
| − | | |
| − | When the Document Responder needs to report an error or warning, it shall use HTTP error response codes and should include a [http://hl7.org/fhir/STU3/operationoutcome.html OperationOutcome] with more details on the failure or warning. If the Retrieve Document message is processed successfully the HTTP status code shall be 200.
