The referral module is described as mmlRe:ReferralModule. For easier use, an unstructured, flat form was adopted for the elements included in this module. Since the referral module considers MML as a higher-level standard, the provisions included in the MML specification apply to the referral module as well.
The referral module specifies a data exchange method for linking hospitals and local clinics, based on letters of referral. Although letters of referral are documents offering clinical information written in Form 6, the form of each referral letter issued by a given medical facility may differ slightly from Form 6. Here, based on Form 6, the minimum data sets for data exchange are defined and presented. The minimum data sets refer to the minimum vocabularies used for definitions for letters of referral in the newly established module in MML. When a letter of referral is actually written, for example, the patient information module already defined in MML is used for patient information. More specifically, an element group defined by the mmlPi:PatientModule is used for patient information such as name, birth date/year, address, and telephone number, etc.
Data such as images, test results, and prescriptions that may be attached to letters of referral are already classified by the mmlCm:medicalRole in the MML common format, the external reference format. For these data, it is recommended that external files viewed from the MML instance be referred to, similarly using the mmlCm:extRef element of the external reference format. On the other hand, it is possible to standardize the mmlRe:testResults with XML by using the test history information module. Furthermore, as for prescriptions, it is possible to describe the mmlRe:medication in a different CLAIM module, which is a data exchange method for linking electronic medical charts and clinical accounting systems. Using this module also makes it possible to standardize the element with XML.
Similarly, for the creator of a letter of referral, the mmlCi:CreatorInfo in the MML common format (Creator information format) is used to match the creator information in the referral module instance with the actual creator of the letter. The mmlPsi:PersonalizedInfo in the MML common format (Personal information format) is used for the medical institution and department of the doctor who creates the letter of referral.
Namespace declaration of this module is as follows.
xmlns:mmlRe="http://www.medxml.net/MML/ContentModule/Referral/1.0"
The "referral" value from table MML0005 is specified in the contentModuleType attribute.
A title that indicates the content of the referral letter should be entered.
For the generationPurpose attribute, the "consult" value from table MML0007 must be specified.
This is the referral module creation date.
The document creator in the referral module is the writer of a letter of referral. The persons who introduces the patient (mmlRe:referFrom) and writes the letter (mmlCi:CreatorInfo) may not be the same due to the use of a substitute writer, for instance.
The mmlCm:extRef element in the referral module is described. The element should be repeated only the same number of times as the number of external link information items.
Only a single referral module should be entered in a single content.
Description: referral module. A single act of a creation of a referral letter by a single doctor is described in a single module.
Description: patient information, such as name, birth date/year, address, and telephone number. Refer to the MML module (Patient information module) for the structure.
Description: parent element for the input of information on a person who introduces a patient.
Description: person who introduces a patient. Refer to the mmlPsi:PersonalizedInfo in the MML common format (Personal information format) for the structure.
Description: title of a letter, such as letters of referral, clinical information offering forms, etc. This element has been set up on the assumption of test request forms in future.
Description: diagnosis. Within this element, diagnoses are written in an unstructured form using XHTML. If a structured diagnosis is required, a diagnosis record information module is created separately and linked with the referral module by the groupId.
Description: past history. This can be present together with text data (#PCDATA) and the mmlCm:extRef.
Description: external reference. When a figure or graph is attached, the MML common format (External reference format) is used.
Repetition: allowed. If multiple external references are available, the element should be repeated the number of times.
Description: family history. This can be present together with text data (#PCDATA) and the mmlCm:extRef.
Description: external reference. When a figure or table is attached, the MML common format (External reference format) is used.
Repetition: allowed. If multiple external references are available, the element should be repeated the number of times.
Description: progress of condition. This can be present together with text data (#PCDATA) and the mmlCm:extRef.
Description: external reference. When a figure or table is attached, the MML common format (External reference format) is used.
Repetition: allowed. If multiple external references are available, the element should be repeated the number of times.
Description: test result. This can be present together with text data (#PCDATA) and the mmlCm:extRef.
Description: external reference. When a figure, graph, or table is attached, the MML common format (External reference format) is used.
Repetition: allowed. If multiple external references are available, the element should be repeated the number of times.
Description: progress of treatment. Refer to the mmlSm:clinicalCourse of the MML module (Clinical summary information module) for the structure.
Description: current prescription. This can be present together with text data (#PCDATA) and the mmlCm:extRef.
Description: external reference. When a figure, file, or table is attached, the MML common format (External reference format) is used.
Repetition: allowed. If multiple external references are available, the element should be repeated the number of times.
