Dear all, Within the Virgen del Rocio University Hospital we are analysing how to implement a EHR based on Dual Model Approach. When we analysed direct implementation a database based on of either OpenEHR Reference Model or ISO 13606, we have detected that it could have slow performance . Given that we are concerned about this problem, we would like to know possible strategies have been identified by implementers in order to fasten the performance of storage and query.
Also the granularity level is one open issue that impacts on the performance, I would like to know if the level of granularity of the archetypes contained within the OpenEHR CKM is able to satisfy the requirements of an EHR with more than 1 million records.
