29、ange of information in machine readable and machine processable formats. As automated interchange of information in healthcare increases, it is essential to provide appropriate information interchange standards. Computer systems are now used by many healthcare professionals for the storage and proce
30、ssing of information. Healthcare professionals request specialist services from one another by a process commonly called “referral”. The request for a service is usually accompanied by a relevant subset of the information held by the requesting healthcare professional about the referred patient. The
31、 recipient of a referral request usually reports on the progress and outcome of the requested service to the requester and to other healthcare professionals involved in the care of the patient. These reports may be made when the requested service is complete (commonly referred to as “discharge”) or
32、at other significant points in the delivery of the requested service. The information that is transferred in the requests and reports passing between healthcare professionals typically forms part of the administrative and clinical record of the patient held by each of the communicating parties. Elec
33、tronic transfer of these requests and reports reduces the need for manual data entry and the risk of transcription errors. It also results in greater efficiency leading to better healthcare provision. Standards are required to facilitate electronic transfer of requests for and results of the deliver
34、y of healthcare services between the many systems currently used. Implementation of this European Prestandard will therefore: a) facilitate the electronic transfer of requests for specialist services from requesting healthcare parties, to healthcare parties providing specialist services; b) facilita
35、te the electronic transfer of reports of specialist services from healthcare parties providing specialist services to requesting healthcare parties and to other healthcare parties involved in the care of a patient; c) reduce the need for human intervention in information interchange between applicat
36、ions used by specialist service providers and those used by other healthcare parties; d) minimise the time and effort required for the introduction of information interchange agreements; e) reduce the development effort required by suppliers to allow communication between a wide range of application
37、s in this field; f) reduce (in consequence of the foregoing) the cost of information interchange between specialist service providers and parties requesting specialist services. When implementing information exchange based upon this European Prestandard data protection and secrecy principles must be
38、 guaranteed according to the laws actually in force in the different CEN member countries. The method by which this European Prestandard has been developed is based on the recommendations of the CEN Technical Report “Investigation of Syntaxes for Existing Interchange Formats to be used in Healthcare
39、” (CR 1350:1993), and as extended in the First Working Document produced by PT3-025. This standard is intended for use by message developers. Its provisions are directly relevant to suppliers of computer systems for use in diagnostic service departments, hospitals, general practices, clinical depart
40、ments and specialist clinics. Its provisions are also relevant to those planning, specifying, procuring or implementing information systems for use in hospitals, general practices, clinical departments and specialist clinics. The main normative provisions in this European Prestandard are expressed i
41、n clauses 4 and 5 and apply to the General Message Descriptions (GMDs), clause 7. The symbols used in this Prestandard have the meaning as defined in normative Annex A for the purposes of this Prestandard only. Informative Annex B provides additional explanation to the General Message Descriptions.
42、Informative Annex C gives a number of example scenarios of message use. A supplementary document to this pr-ENV, called “Generic EDIFACT message implementation guide”, provides in its first chapters the method and conformance information on how the EDIFACT messages meet the requirements of the Gener
43、al Message Descriptions of the pr-ENV.ENV12538:1997 6 BSI 06-1999 1 Scope This European Prestandard specifies general messages for electronic information exchange between computer systems used by healthcare parties requesting specialist services or receiving reports from specialist service departmen
44、ts. 1.2 Examples of requests for healthcare specialty services include: referral of a patient from a GP to a hospital clinical specialist; referral of a patient for direct entry for an open access procedure; referral of a patient for direct entry onto an operation waiting list; referral of a patient
45、 for emergency hospital admission (acute referral); referral of a patient for treatment by a paramedical specialist; referrals within a hospital from one specialist to another (tertiary referral); referrals between hospitals or GPs and a community health service provider. 1.3 Examples of reports of
46、healthcare specialty services include: issue of a report including the planned action and information relating to appointment and patient transport arrangements; issue of a preliminary discharge report following a patients admission to hospital; issue of a final discharge report following a patients
47、 admission to hospital; issue of report arising from a single out-patient attendance by a patient (this may be considered to include attendance at a daycare facility); issue of a report summarising a series of out-patient attendances; issue of a report giving information about a patient when no imme
48、diate patient contact occurred (for example, to communicate the result of investigations that were not available at the time of an earlier report, or to make suggestions about treatment when no direct treatment occurred); notification of a referral by one specialist to another specialist (tertiary r
49、eferral notification); notification of the admission of a patient to hospital; notification of the death of a patient in hospital. 1.4 The messages are also applicable to modifications or cancellations of previously issued requests or reports. 1.5 While the messages specified in this European Prestandard may convey clinical and administrative information concerning patients, the way in which this information is treated in this European Prestandard does not c
