0. INTRODUCTION
This specification provides the definition of the Medical
service request message (MEDREQ) to be used in Electronic Data
Interchange (EDI) between trading partners involved in
administration, commerce and transport.
1. SCOPE
1.1 Functional Definition
A Medical Service Request message is sent from a service
requester to the service provider to order investigations, to
modify a previous order or ordered investigation or to cancel a
previous order.
1.2 Field of Application
The Medical service request message may be used for both
national and international applications. It is based on
universal practice related to administration, commerce and
transport, and is not dependent on the type of business or
industry.
1.3 Principles
The message fulfills the requirements of the European
pre-standard concerning messages for exchange of laboratory
information within clinical chemistry, clinical biochemistry,
toxicology, clinical immunology, immunohaematology, haematology
and clinical microbiology. The message may, however, also be
used for other purposes as long as the user requirements are
meet.
The CEN prENV New Laboratory Service Order message and the CEN
prENV Laboratory Service Order Cancellation message may be
considered as special cases of the CEN prENV Laboratory Service
Order Modification message. The Laboratory Service Order
Modification message may contain a mixture of new, change,
cancel and other service types for the order itself and for the
various requested investigations whereas the New Laboratory
Service Order message only contains the new service type for
the order itself and the various requested investigations and
the Laboratory Service Order Cancellation message only contains
the cancel service type for a complete order.
The overall structure of the message is:
- One message may include one or more service orders.
- The service order is connected to one service provider, one
service requester and optionally one or more parties to receive
copies of the order and/or subsequent result message(s).
- Every service order is related to one main subject of
investigation (patient, animal or material), but may also
include information about several related subjects of
investigation.
- Every service order may request services concerning one or
more samples (from the same subject of investigation) or the
subject of investigation itself.
- Every sample may have one collection site.
- A requested investigation may be connected to one or more
samples or to the subject of investigation itself.
With the exception of information in FTX segments, all
information should primarily be expressed as codes.
