We need to think as per end users point view. What is a use of reference model to end user? will it simplify the transaction. This a thought I want to share with you.

It's basic and most important use is to provide reference to checkthe correctness of the arquetypes. 2. It is needed for some types of persistence design Why am I asking myself this? because once assertions are implemented,all that may be needed for validating real data may be included inarchetypes, can't it? am I missing something? thank you - Rodrigo FilgueiraAsistente Docente/InvestigadorNúcleo de Ingeniería Biomédica, FING - UDELAR __ Do You Yahoo!?

Thanks Gerard , This gives some understanding of RM. Will it be more useful if we can understand it in more end user perspective?

Thanks Sam, Your explanation has been very useful to understand RM. I work more in implementing EHR and HIS and deal with users. Gerard gave the technical explanation but I thought it will be useful if I can understand it in user?s point of view. Your explanation has solved my query. I think while system design and development, user perspective is very important. It should based on real life use cases and scenarios I thank you and Gerard for clarifications. Regards, Ankush --- Sam Heard wrote: - Ankush It is a recording model that contains features required for all legalrecording and audit trail, for tracing inputs and outputs and is thebasis for all software. The software has to know about the referencemodel. The reference model means that the EHR can accept anyinformation at all - the way specific information is recorded dependson the archetype (but it always uses the features of the referencemodel!). The clinical concepts are expressed in archetypes. Most software usingan EHR service will not need to know what is in archetypes - just howto work with archetypes. So data entry, display and other componentsneed to be archetype-aware but not understand the clinical concepts.The components for data entry can have archetype-specificspecifications (we call them templates for data entry and displayscripts for viewing) of how to present this to the user. Decision support and clinicians need to know what an archetypeexpresses - because the health care of a patient will depend on this.Some other smart software will as well - perhaps determining thebilling automatically - etc. Does this help?
